I have an XML content, for which I do not know which class it belongs to Need to create a dynamic Java object? Is it possible to do this? It can be a simple Java object, so we can use the Java Reflection to get value from that object. For example,

  & lt; Employee & gt; & Lt; Name & gt; Jack & lt; / Name & gt; & Lt; Designation & gt; Manager & lt; / Designation & gt; & Lt; Department & gt; Finance & lt; / Department & gt; & Lt; / Staff & gt;   
 So, with this XML, I need to convert to an employee object. But, I did not have an employee class in my class path, is it possible to create an object with XML?   
 
 
  file fxmlFile = new file "Employee.xml"); Documentbilder factory dbfc = documentbilderfactor.Newinstance (); DocumentBuilder debugger = DBFTC NE DocumentBuilder (); Document doctor = debugger Parse (fxma file); // Optional, but recommended // read this - http://stackoverflow.com/questions/13786607/normalization-in-dom-parsing-with-java-how-does-it-work.doc.getDocumentElement (). Normal ( ); System.out.println ("Root Element:" + doc.getDocumentElement (.) GetNodeName ()); Node list nList = doc.getElementsByTagName ("employee"); Println ("----------------------------"); (At Temp = 0; Temp & LT; NLIIT: ATLANMENT (); Temporary ++) {Node NND = NLIT. ITM (temporary); System.out.println ("\ n Current element:" + nNode.getNodeName ()); If (nNode.getNodeType () == node. ELEMENT_NODE) ​​{Element EElment = (Element) nNode; System.out.println ("name: -" + eElement.getElementsByTagName ("name"). Item (0) .getTextContent ()); System.out.println ("Designation: -" + eElement.getElementsByTagName ("Designation"). Item (0) .getTextContent ()); System.out.println ("Department: -" + eElement.getElementsByTagName ("Department"). Item (0) .getTextContent ()); }}    

 

I know there are so many questions on this topic, but they are all in accordance with a specific case. I am asking this question and hoping for an answer that everyone can use it while thinking about this matter.

Say that I have three functions that need to be executed in order, and they all do Async

For two tasks it is easy with callback: / P>

  var fOne = function (callback) {// do stuff callback (); }; Var fTwo = function () {// do stuff};   
 Calling:  
  fOne (fTwo);   
 The FOO makes it to run after completion, how does the FTH in this case connect, so that it can be run after FTO, which is run after FOn? 
 
 
 Actually, if I think your question is correct, then you can add a logic to the FTO If you want to pass Lambda, then FTO has to take a callback and call it.  
  var fOne = function (callback) {// do stuff callback (); }; Var fTwo = function (callback) {// do stuff callback (); }; Var fThree = function () {// do stuff}; Fun (function () {FTO (FT-2);}); // & lt; - Lambda    

 

visual studio 2012 - Why does select source for a SQL Schema Comparison cause VS2012 to crash? -

For instance, SQL & gt; Compare schema & gt; Visual Studio 2012 causes crash due to new schema comparison and then "attempting to select the source". Apart from trying to re-establish any possible solution there (hopefully for months it has been worked out)

I am using StringTemplate to create HTML and I use STGroupFile and STGroupDir This way I have a directory of group files. In this way I can include multiple templates in a file, but I can add templates from many files. It does not appear that there is support for it, but I thought that if I see something then I will see it.

If you are wondering why I would like to do this, see an example from the StringTemplate Docs:

  test (name) :: = "$ name: bracket () $ "// Apply bracket template in each name bracket (x): =" [$ x $] "// parameter parameter with square bracket   
 All the above one file (Test.st) and we are using  STGroupDir , it will be unable to resolve the "bracket (x)" template unless it is a separate file (bracket.st) Not in In this particular example, the bracket is like a local assistant that is useful for cleaning the main template. In this case, you probably do not want to show the bracket outside of the test.  
 However, if you want to create a library of simple supportive templates, you can find them all in one file and each of them is accessible to templates in other files.  
 "post-text" itemprop = "text"> 
  Disclaimer: I am using  StringTemplate  in C #   Em>  
 You have to use  .stg  files with a group of templates.  StringTemplate  groups can import groups of other templates or templates, and you can create those groups from a file or directory.   

 

It seems that I can only return the contents of a folder, but there is no information about the folder.

  Result = client.execute ({: api_method => drive.files.list,: q = & gt; "mimeType = 'app / vnd.google-apps.folder' and Trashed = false and title = '# {App_folder_name}' ",: maxResults => 1})   
 returned results. To_hash ["Item"] is populated with the contents of the array folder (sub folders and files). How do I get information about folders only? What I want to do, checks whether it exists or not. And it seems that more than one entry is being neglected in the array.   
 
 
 A folder Google Drive is like a regular file but a special MIME type ("app / vnd. Google-apps.folder "). After you have the ID of the folder, you can access the metadata with a request:  
  ## # Print the file's metadata # # the ultimate [Google :: epicilient] Client #Official Client Instance # @ PRAM [String] File_ID # To print the #RetinNil DRP print_file (client, file_id) drive = client. Diskped_pi ('drive', 'V2') result = client.execute (: api_method = & gt; @ drive.files.get ,: parameter = & gt; {'fileId' = & gt; file_id}) if result.status == 200 file = result.data "title: # {file.title}" puts "Description: # {file.description}" puts "MIME type: # {file.mime_type}" and adds "An error occurred: # {Result.data ['error'] ['message']} "end and end    

 

I have a large TSV file that I can not read in R due to its size.

I only want to read the header name in the selected column, e.g. "Health".

How can I go about doing this?

See a read.table code colClasses : df & lt; - read.table (header = TRUE, colClasses = c (NA, "NULL", NA), text = 'ABC 1 2 3 4 5 6') DF # AC # 1 1 3 # 2 4 6 < / Pre>

Update:

To select names, first read in the header and then create a vector for the callclass:

  Read the # header header; & Lt; - read.table (header = FALSE, nrow = 1, text = 'ABC 1 2 3 4 5 6') # We want to take the call & lt; - c ('A', 'B') # Create a vector for callclose lecols & lt; - ifelse (t (header) %%, na, 'toll') # selected column df & lt; - read.table (header = TRUE, colClasses = lecoles, text = 'ABC 1 2 3 4 5 6')    

 

I enable a QPushButton after another QPushButton Trying to click and I have participated in a problem first QPushButton one clicked () can remove the signal, while the second QPushButton has only the setEnabled (bool) slots and set to disable (boole) .

Actually, I am trying to do

  connect (ui-> pbViewVolume, signal (clicked)), UI-> pbSaveAsImage , Slot (setEnabled)));   
 Since it is not possible to send a signal with less parameters compared to the slot, how can I do this? My only way is my  main window  like  
  zero EnableSaveAsImageButton () {ui- & gt; PbSaveAsImage-> To create a public slot for setEnabled (true); }

I weakened an assembly using ILSPT, public class customsstream : Network Stream {Private Event Handler & lt; Custom Event Egg & gt; SomeEvent; Public events event handler & lt; Custom Event Egg & gt; Add SomePublicEvent {add {EventHandler & lt; CustomEventArgs & gt; EventHandler = this.someEvent; Eventhandler & LT; CustomEventArgs & gt; EventHandler2; Do {eventHandler2 = eventHandler; Eventhandler & LT; CustomEventArgs & gt; Value2 = (Event Handler & lt; CustomEventErgies & gt;) Representative Cobain (eventhandsler 2, value); EventHindler = Interlock Comprex Exchange and lieutenant; EventHandler; & Lt; CustomAventAge & gt; & Gt; (Referee this Somewant, Value 2, EventHandler 2); } While (eventHandler! = EventHandler2); } Remove {// Similar stuff ...}}}

In the next code, it seems that a real incident is set to fire a personal representative:

  if (some! = Null & amp; amp; something; ele =!) {This.someEvent (this, new CustomEventArgs (someArg)); }   
 Question: Can anyone guess what the idea behind this custom accessor could be, assuming that some "compile / divide magic" was not done? I am not very familiar with IL, BTW ...  
 (Side note: application is multi-threaded and uses networking, obviously.)   
 
 
 This is a new event handler code generated by the compiler. It was launched in C # 4 (C # version was different)  
 Interlock Comparx Exchange compares the first argument with the third, and if they are equal, then the second argument changes with the other. This is a thread-safe operation Loop is used for any case when a variable eventHandler2 and check Prior to this, a thread changes to this representative. In this case, interlock Compressed Exchange does not execute the exchange, the position of the loop is correct and does not evaluate the next attempt.  
 Generates simple code in C # 3 event handlers:  
 Add  lock (this) {changed = change = value;

ssl certificate - How to use multiple SSL Keys when using two different git servers? -

I have currently set up a personal installation on a private server for use on private repos.

I also have to use the company's GTBLT to set up projects for the company.

In a whole world, I will be able to use (like Geethabs) and can configure different SSP keys for each server. / P>

Unfortunately GitBlit has chosen to use SSL and has not used SSH. Installing a single SSL certificate for GIT is really simple.

  git config --global http.sslKey path / to / username.key   
 but the global feature in settings appears like I have This is the only way to override the  GIT_SSL_KEY  in this project, or can there be only one key, or whether there are two different types within the global setting (IE: pointing  http: sslKey  - There is a way to use different SSL keys) in  .keyig  file instead of  .config )   
 
 
 You can configure a project differently except the  - global  argument and run it in the folder for the project you want to configure.  
 For example:  
 
 
 Configure the company's SSL key as the global default key  
  git config - -global http.sslKey path / per / company.key    
 
 Configure each private repo with your private key  
  CD / My / Private / Repo Git config http.sslKey path / to / private.key      

 

php - alert only file names selected from file input -

I have this Ajax call that checks if the name of multiple file input in a file already exists, and if When they do, a message warns them by telling them this. The problem is that I can only get it to alert all the file names from the result loop. How can I edit it so that it can only alert file names that were selected? Thank you.

  var file = $ ('# file') [0]; $ .get ('existing-filenames.php', function) {for (var i = 0; i & lt; file.files.length; i ++) {var fname = file.files [i] .name ;; (~ Data.indexOf (fname)) {// Only alert selected file name warnings ("These files already exist:" + data); return false;}}}, 'json');   
 and existing-filenames.php  
  $ allfiles = $ db- & gt; Query ("Select file from files where email = '$ _SESSION [email]'); $ Result = []; While ($ files = $ allfiles -> fetch_assoc ()) {$ result [] = $ files ['filename']; } Echo json_encode ($ result);   
 and html  
  & lt; Input name = "file []" type = "file" id = "file" multiple / & gt;    
 
 
 In doubt, add more jQuery:  
  $ ('# File'). ('Change', function () {var self = this; $ .get ('existing-filenames.php', function (data) {$ .each (self.files, function () (if (data.indexOf (this .name)! = -1) {Warning ("These files already exist:" + + this.name);}});});});

I have a celery that is called, just ignite the execution of some parallel code inside a twisted reactor. is. For example, there is no sample (runan) code:

  def run_task_in_reactor (): # to do this takes some time do_something () do_something_more () @ celery.task def run_task () : The print "reactor was started" reactor calfarththread (run_task_in_rector)   
 (For simplicity, please assume that the reactor is already running when the worker gets the work;   As soon as the other thread in my reactor  
 When I call  run_task.delay () , the task is finished very quickly (because it  run_task_in_reactor ()  does not wait to finish, only determines its execution time in reactor). And, when  run_task_in_reactor ()  runs at the end,  do_something ()  or  do_something_more ()  can throw an exception, which will be untold.  
 To use  pika  to consume my line, for example, to inform the worker about the correct completion of the job, I  do_something_more ()  However, inside the celery, this does not seem possible (or, at least, I do not know how to make the same effect complete)  
 Also, I can not remove the reactor because it One requirement is using some third-party code. I also appreciate other ways to achieve the same result.   
 
 
  Use reactor. BlockingCallFromThread  instead.   

 

Are there downsides to using var more than once on the same variable in JavaScript -

Before asking my questions, I want to make a disclaimer I know what var does , I know about block scope, and I know about moving the variable I am not looking for answers to those topics

I'm just thinking that more than one variable within the function But using a variable declaration is a functional, memory or performance cost.

Here's an example:

  function foo () {var i = 0; Whereas (i ++ & lt; 10) {var j = i * i; }}   
 The last code can be easily written  j  variabled has been declared at the top:  
  function Foo () {Var i = 0, j; While (i ++ & lt; 10) {j = i * i; }}   
 I am thinking that there is no real difference between these two methods. In other words, does  var  do anything other than the scope of the keyword?  
 For this reason I have heard the second method to like:  
 
 The first method gives the scope of the block when it actually works scoped.  
 Variable dispersion is hoisted at the top of the scope, so it should be defined where.   
 I consider these reasons as good, but are primarily stylish other reasons which work more with functionality, memory allocation, performance etc.?   
 
 
 There will be no difference during the  execution time . Interpreting / compiling time can be a susceptible small difference, but surely implementation will depend. Some bytes in the file size can also be different, which can affect download time. I do not think there is any concern about any of these.  
 As you already know, any variable declaration will be hoisted at the top of the function. The important thing to note is that  is done during the interpretation / compilation process, not during execution. Before the   
 function is executed, the function   should be parsed after every function is parsed, all the variables will take declaration declarations to the top of which It means that they will be identical and there will be no execution time cost.  
 For this reason, there will be no memory cost differences after parsing,  no difference  will be.  
 
 Since you are not asking about style, I am not telling you what I think is better. But I would say that the only reason you should prefer more than one is style.   

 

Starting debugging only from a certain point in time in C# with Visual Studio -

I have a program that has a small Tetris like a game. I have a problem with my collision detector in some configurations, I want to debug it, but the game does not start in the "problematic" situation, I want to get the game in this situation and only want to start debugging. Since the collision detector runs very often, I can not put a breakpoint at a place that I will know that I will only run after the problematic situation, and the debugging process focuses on the game window, and allow me to give it Not input with keyboard.

Using Visual Studio 2012, is there a way to start the debugger shortly after, where initially it will ignore the breakpoint, and only after telling it it starts breaking on the break point To do?

Yes, you can start without debugging and then when you use the debug menu , You want to go to the state, select Attach the process when you are presented with the list, then double-click on your app.

Another potential solution is to disable the breakpoint and then when you want the state (in which you start with debugging), simply enable breakpoints with a breakpoint window.

regex - Find text string or part of text with dot in grepWin -

I am using grepWin on Windows 7 64

I have a folder with files and their duplicate copies.

The original files are named "FILENAME DOT FILETYPE" (without spaces), for example "cartonbox.shelf".

Copies of these files "FILENAME DOT 1 DOT FILETYPE" (without spaces), for example "cartonbox.1.shelf".

I am trying to find all the files containing the exact string:

"DOT 1 DOT FILETYPE" (without spaces), so in all those files For ".1.shelf".

How can I do this in grepWin?

If I did not get any result for ". 1 \ shelf " or ". 1 \ .shelf " example

What is my fault? By reading but can not come with the correct pattern.

How can I usually search for the exact portion of the filename in spite of symbols?

Actually if I want to find the file "garden_1.1.4-JE50.tree" in the example how do I tell grepWin to find this exact string of text, including underscore, dots, or other characters?

This file searches, files Do not search names

In the directory you want to find, you can do something like this:

  dir *. * / B / s> My_file.txt   
 Then you can do my regular expression with grepWin on my_file.txt  
 In Unix and Linux, you can normally go through the command line Command pipe:  
  LS-A | | Grep \ .ree $   
 In Windows you will use  
  dir * / b | Findstr \ .ree $

Eclipse Color Theme: "Color Theme" not showing up -









        
 
 
 
 I am trying to change how I work, so I can not get headache after 8 hours sitting on the computer I want to play with colors in Eclipse so that it can help.  
 I have appreciated this eclipse color theme plugin.  
 I am installing through Eclipse Marketplace, I drop an .xml file theme in the "dropins" directory in the eclipse directory located on my hard drive, window-> Prefrences-> Normal-gt; Apperence-> ??? Choose "color theme" where? It's not just there!  
 Does anyone know what can be the problem? I am running Eclipse Juno EE with another plugin EGIT.  
 Install manually? I have already re-installed the color theme plugin twice! [Solution] I just got a problem with the help of another post I was not running as an administrator because my program file directory is safe Answer: Always accept eclipse as administrator or linux Run on the system SUDO.    
 
 
 No, the correct answer is to open the eclipse at a location, where it is root / administrator access Can write without even Do not insert the eclipse in the "Program Files" folder.  
 Historically, the eclipse is designed to be modified in its own right, and when you can not establish it, do this and you can write it through eclipse.ini settings in the writeable area. Not indicated by.   

 











python - 'int' object is not subscriptable -









        
 
 
 
 My code for printing a matrix as a class is as follows:  
  i Range (1, lane (a [ii])): range (1, lane (a) for line = "\ t" "+ str (a [i] [0]) [I]): line = line + "\ t" + str (a [i] [j]) line = line + "|   
 Where there is a list [22, 38, 30, 58, 34, 69]  
 It should look  
 | 22 38 |  
 | 30 58 |  
 | 34 | 69 |  
 It is coming back 'int' is not responsible for the line in the object code :  
  line = "\ t" "+ str (a [i] [0])   
 How can I fix it?  
  
 
 
  A  is a list - a one-dimensional array  A [0]  is a  int , which is not subscriptable because of your error.  
 It is more natural to represent the matrix in the form of a two-dimensional list in Python, such as:  
  A = [[22, 38], [30, 58], [34, 69]]   
 or  
  A = [[22, 30, 34], [38, 58, 69]]   
 If you do this then your code will work, however it would be better to use the code like this:  
  def print_matrix (M): For M in M: print ("| {} |" .format ('\' for O for O (O))) print_matrix (a)   
 or Even the bus:  
  If you are tied to your single dimension for A, you can print it like this:  
  Def print_list_metrics (m, width): for i, zip (range (0, lane (m), width), range (skip, lane (m) + width, width)): print ('| {} |'   
 Or like it:   
 for O in (.frat ("str (hey)) for .format (" \ t " P>

swing - Class Structure and Location for MVC in Java -









        
 
 
 
 I am writing a GUI for the Sudoku program. I am trying to use an MVC framework, the following post was the basis of the basis of my current code: My question is where do the action listeners go? I think they go to the controller, but is that one class or many? Currently I have a single class with a single action listener and if there is any other argument to deal with each swing component which can fire an event. This code smells for me though. Is there a preferred way to structure code? I hope some more buttons and components have to be added and I want to make sure that I am doing it down properly. I've read a lot of posts and web tutorials, but have received this answer so far.  
 Thanks  
  The public class provides SudokuView JFrame {sudoku controller controller; // Sudoku Engine Sudoku Engine; Personal fixed final end yMar = 100; Private stable final int xMar = 25; Personal static final difference cellSize = 40; Private stable final interval grid space = 3; Private constant final integer secondspace = 9; Personal fixed final full width = 2 * xMar + 9 * cells + 2 * second space + 6 * gridspace + 10; Private stable final intensity height = 650; Public pocket [] [] gridbutton; Public sudoku () {controller = new sudoku controller (); // sudokuEngine = new Sudoku engine (); Gridbots = new pocket [9] [9]; SetTitle ("Sudoku Ninja 0.1"); SetSize (width, height); SetDefaultCloseOperation (JFrame.EXIT_ON_CLOSE); SetLayout (zero); SetBackground (Color.GRAY); SetResizable (wrong); DrawBlankGrid (); SetVisible (true); } Public Zero SetSudoku Implementation (SudokuInine Interface Listener) {Controller.

  count = 0; For X = 0.2: 0.1: 1 calculation = count + 1; One (count) = quadruple (h, 0.2, x) end    

 











android - How to implement search widget with a listview using
SherlockActionbar? -









        
 
 
 
 So, I'm trying to implement this code on my application, but no success yet.  
 This is my main activity. Java:  
  import java.util.List; Android Import Search manager; Import android.content.Context; Importroid.os.Bundle; Import android.widget.ArrayAdapter; Import android.widget.SearchView; Import com.actionbarsherlock.app.ActionBar; Import com.actionbarsherlock.app.SherlockListActivity; Import com.actionbarsherlock.view.Menu; Import com.actionbarsherlock.view.MenuItem; Public Class Main Activity Expands Sherlock Holistic Activism Options / Public Sector Main Activity List Extension Action ActionBar.TabListener {Private List & lt; Scos & gt; Scoss; ScosDataSource Datasource; @ Override protected void saved create (bundled Instansstet) {Suprknkret (saved Instensstet); SetContentView (R.layout.activity_main); Datasource = New ScosDataSource (this); Datasource.open (); Scaus = datasource.findal (); If (scoss.size () == 0) {createData (); Scaus = datasource.findal (); } RefreshPrint (); } @ Override Public Boolean On Crate Option Menu (Menu Menu) {// Enhancing Menu; It adds the item to the Action Bar if it exists GetSupportMenuInflater (). Flood (R.menu.options, menu); SearchManager searchManager = (SearchManager) getSystemService (Event.SEARCH_SERVICE); SearchView searchView = (SearchView) menu.findItem (R.id.menu_search) .getActionView (); If (null! = SearchView) {searchView.setSearchableInfo (searchManager .getSearchableInfo (getComponentName ())); SearchView.setIconifiedByDefault (wrong); } SearchView.OnQueryTextListener queryTextListener = new SearchView.OnQueryTextListener () {public boolean onQueryTextChange (string newText) {// This will be adapters filter that your adapter. (Filter) (newText); Back true; } Public Boolean onQueryTextSubmit (string query) {// This is your adapter that will be adapted by the adapter.fifter. Filter (query); Back true; }}; SearchView.setOnQueryTextListener (queryTextListener); Return Super.

 This is my option. Xml:  
  & lt; Menu xmlns: android = "http: // schemas Android.com/apk/res/android" & gt; & Lt; Item android: id = "@ + id / menu_search" Android: actionViewClass = "com.actionbarsherlock.widget.SearchView" Android: showAsAction = "ifRoom | collapseActionView" android: icon = "@ drawable / ic_action_search" android: title = "@ Search "& gt; & Lt; / Item & gt; & Lt; / Menu & gt;   
 
 "> 
 I hope that helps because I had only one problem.  < p> the best way to use adapters that class is applied to the SearchView.OnQueryTextListener and then you do not have to make this internal class and you'll have the adapter.  
 in your code it will:  
  public class Menaktiviti Sherloklist Aktiwwaiti Oplements extended takes SearchView.OnQueryTextListener   
 And then in the class you have to define the methods the adapter adapter will be in your class array adapter adapter. But you should define it in the class as private  
  public Boolean onQueryTextChange (string newText) {// This filter will be filtered (newText) to your adapter.getFilter (). Back to true;} Public boolean onQueryTextSubmit (string query) {// This is your adapter which is the adapter. Effil Filter will be filtered (query); return true;}   
 where the lines are set:  
  searchView.setOnQueryTextListener (queryTextListener);   
 should be:  
  searchView.setOnQueryTextListener (this);   
 If you have any problem tell me, today I am with a similar problem and read the answers without your question.

eclipse rcp - RCP P2 Update for base productin -









        
 
 
 
 I am developing an RCP P2 update.  
 
 I have created the RCP mail template application. (Com.project.app.mail)  
 I have added the product configuration file MailProduct.product  
 I have the ORGP. Org.eclipse.equinox.p2.ui.sdk added tabs as a dependency in reliance, after adding my plugin project to it, I found the Intall New Software and Update for Check option under the Help menu.  
 
 I've added the p2.inf file with the following content.  
 instructions.configure = \ AddRepository (type: 0, location: http $ {# 58} // localhost: 8080 / REPO /); \ AddRepository (type: 1, location: http $ {# 58} // local host: 8080 / REPO /);    
 
 I convert a product to convenience.   
 I have created a feature project (com.project.feature.mail)  
 I added com.project.app.mail to the plugin tab of the feature. Com.project.feature.mail  
 I launched the RCP product through the product file. It failed, I went to run the configuration, the required plugin added application was successfully launched after that.  
 I exported the product and the exported products worked fine.  
 I've made some changes to com.project.app.mail now.  
 Updated com.project.feature.mail verstion 1.0.100.quailfier (formerly version 1.0.0 .colfire)  
 Added an updated site project. Added mail feature with category code 1.0.100.qualifier added with com.project.category.mail.  
 Clicked on all, transfered generated features, plugin, artifact and repository.exam created in a local HTC server (Tomcat)  
 I updated to com.project.feature Tried to update .mail, check the update option.  
 It says that no updates have been found, while updated to the new software page com.project.feature.mail update verio. In progress with the installation, it indicates that the update is possible, while the update can not get the new update.   
 Please note how to provide updates for the base product.  
 If you have any other information I need to know.   
 
 
 Dear Priyaalank is your product (Mailpand.Product) version? The following suggestions will solve your problem.  
 
 You must also change the MailProduct.product version.  
 Re-export your product with generating metadata repository options.  
 Use this repository on your web-server to receive updates.  
 Software updates with updated site projects do not work so easily.    

 











How do I export a MS Access report to PDF with a formatted ID value as
the report name? -









        
 
 
 
 I am using Access 2007.  
 I have created a button that I want to know for my current invoice for a .pdf and in the name of it "invoice number plus client name" and i'm close but not yet it is currently The code exists and it works fine:  
  Personal sub Create_Document_Click () DoCmd.OutputTo acOutputReport, "Invoice", acFormatPDF, [Invoice_ID] & amp; "_" & Amp; [Client_id] & amp; ".pdf" and sub   
 This gives me a report called "1_1.pdf" which is called "1007735001_XYZCompany.pdf".  
 In my invoice table, I have formatted the invoice_ID field, which is an auto number field, "1007735" 00 but the report records the output as 1 as the formatted number, I First we need to know if I can change it to show this formatted value. Is this possible?  
 Then I would like to know that I can change client name from 1 to client name. My field name is Client_ID and Client_Name and the table is called Client.  
 I have searched through many forums and have tried many solutions but all have given me errors, any help would be greatly appreciated. Please tell me if I need to give more information.   
 
 
 You have committed many sins. You should not add formats to tables, as you have found, the format is just one format, this does not change the content of the field (). In the editor, you have a look for client ID, another anti-feature () Has added up  
 You will need to see the client again and reformat the number.  
  Customer = DlookUp ("ClientName", "ClientTable", "ClientID =" & [Client_ID]) Invoice = Format ([Invoice_ID], "" "1007735" "000") FileName = Invoice & amp; "_" & Amp; Customers & amp; ".pdf"

  9 जवाब     
  मैं कैसे करूँ 1 तालिका से 2 तालिकाओं में डालें?   
 मैं तालिकाओं में जमा करना चाहता हूं: गैलरी और बिल्ली।  
 यह केवल गैलरी में सबमिट करने वाला कोड है I मैं एक साथ बिल्ली तालिका में जानकारी कैसे जोड़ूं?  
  $ sql = 'गैलरी में शामिल करें (image_url, image_name, image_description) मूल्य (?,?,?)'; $ Stmt = $ conn- & gt; stmt_init (); ($ Stmt- & gt; तैयार ($ sql)) {$ stmt- & gt; bind_param ('sss', $ _FILES ['अपलोड'] ['नाम'], $ _POST ['image_name'], $ _POST [' चित्र का वर्णन']); $ ठीक = $ stmt- & gt; निष्पादित करें (); }   
 मैं इसके साथ क्या करूँ:  
  $ sql_2 = 'बिल्ली में प्रवेश करें (cat_name) मान (?)';    
 
 
 आपके ऊपर दिए गए कोड के बाद, बस एक नया स्टेटमेंट प्रारंभ करें, इसे बाइंड करें, और निष्पादित। आप मौजूदा कनेक्शन का उपयोग कर सकते हैं ( $ conn )।  $ sql  और  $ stmt  वेरिएबल्स ने पहले तालिका में डालने से पहले ही अपना काम किया है, इसलिए उन्हें दूसरी डालने के लिए रीसेट करें।  
 < कोड> ... आपका कोड ऊपर पोस्ट किया गया, इसके बाद: $ sql = 'INSERT BIT (cat_name) VALUES (?)'; $ Stmt = $ conn- & gt; stmt_init (); अगर ($ stmt- & gt; तैयार ($ sql)) {$ stmt- & gt; bind_param ('s', अपने cat_name मूल्य को यहाँ रख); $ ठीक = $ stmt- & gt; निष्पादित करें (); }   
 याद रखने के लिए महत्वपूर्ण बात ये है कि दूसरा डालने के लिए पहले की तरह ही है: आपको इसे प्रारंभ करना है, इसे बाइंड करना है और उसे निष्पादित करना है।   < / html>

 











latitude/longitude info in a GML Bounding box -









        
 
 Text after "
 
, for example, we are box bounding as given below in GML:  
 < Code> & lt; GML: envelope & gt; & Lieutenant; GML: Lower Corner & gt; 42,943-71,032 & lt; / Gml: Lower Corner & gt; & Lieutenant; GML: Upper Corner & gt; 43.039 -69.856 & lt; / Gml: Upper Corner & gt; & Lt; / GML: envelope & gt;   
 Now, for the lower corner, wood value is latitude and longitude wood. This information could not be found in the online document.  
 Thanks Stroller  
 GML is formatted in GeoRSS   
 
 < P> From the GML schema:  
  & lt; Complex type name = "envelopeType" & gt; And lieutenant; Options & gt; And lieutenant; Sequence & gt; & Lieutenant; Element name = "lowercondar" type = "gml: directpressation type" /> & Lieutenant; Element name = "upper corner" type = "gml: directpressation type" /> & Lt; / Sequence & gt; & Lieutenant; Element riff = "gml: mail" minicomers = "2" max ockers = "2" & gt; And lieutenant; Annotation & gt; And lieutenant; App Info & gt; Deprecated & lt; / App Info & gt; & Lt; / Annotation & gt; & Lt; / Element & gt; & Lieutenant; Element ref = "gml: coordinate" /> & Lt; / Options & gt; & Lieutenant; Specialty Group Referee = "GML: SRSERFRUS Group" /> & Lt; / ComplexType & gt; And lieutenant; Element name = "envelope" type = "GML: envelopeType" substitutionGroup = "GML: abstract object" & gt; And lieutenant; Annotation & gt; And lieutenant; Documentation & gt; The envelope defines an extent by using a pair of conditions defining the opposite edges in arbitrary dimensions. The first direct "lowest corner" (for all the points within each coordinate position of the coordinates of all the dimensions for continuous matter on the envelope), the second one "upper corner" (for a coordinate position of all the greater coordination The constant thing is for every point within the envelope for each dimension). The use of "coordinate" and "mail" properties is disliked. Clearly named properties "Lower Corner" and "Upper Corner" will be used instead. & Lt; / Documentation & gt; & Lt; / Annotation & gt; & Lt; / Element & gt;   
 Which leads to the SRS ArrayFure Group which contains the code so that you can see axis orders and units (among other things) about your coordinates.  
  & lt; Specialty Group Name = "SRSReferenceGroup" & gt; And lieutenant; Annotation & gt; And lieutenant; Documentation & gt; The specialty group SRSReferenceGroup is an alternative reference for the CRS used by this geometry, to simplify the processing of coordination with additional additional information when more complete definition of CRS does not normally require a CRS of specialty srsName GRL For example, indicates: Abstrack Coordinate Reference System. For famous contexts, it is not necessary that the CRS statement is present in place of the URI. If no srsName attribute is given, the CRS will be specified as part of a larger context. This is part of the geometry element. & Lt; / Documentation & gt; & Lt; / Annotation & gt; & Lieutenant; Attribute name = "srsName" type = "anyURI" /> & Lieutenant; Attribute name = "srsDimension" type = "positiveInteger" /> & Lieutenant; Specialty Group Rif = "GML: SRSI Group Group" / & gt; & Lt; / AttributeGroup & gt;   
 So it is impossible to answer your question without a specified SRS, we do not even know which unit your coordinates are   

 











javascript - How to stop redirect to API call result after form
submission? -









        
 
 
 
 When a user submits an article url, then I use the Clamp API () to return text summary I am trying. When the user submits a suitable URL, they are redirected to a new page with the JSON result. I want to keep the user on the page and parse the JSON string in Javascript. I'm assuming that this redirect has to do with the fact that the form is a link to the verb script, but I'm not sure what to do here. Below is the code  
   & Lt; Script src = "http://code.jquery.com/jquery-1.8.2.min.js" & gt; & Lt; / Script & gt; & Lt; / Head & gt; & Lt; Body & gt; & Lt; Form action = "http://clipped.me/algorithm/clippedapi.php?url=[URL]" method = "find" & gt; & Lt; Input type = "text" name = "url" /> & Lt; Input type = "submit" value = "submit" /> & Lt; / Form & gt; & Lt; / Body & gt; & Lt; Script type = "text / javascript" & gt; & Lt; / Script & gt; & Lt; / Html & gt;    
 
 
 Do not use form submissions to make API calls. Instead use AJAX calls.

jsp tags - Database gets updated with first entry only in liferay -









        
 
 
 
 I have a happy birthday, I display some data in JSP which comes from different tables from database. I have a radio button field on which the user needs to click and then must be updated when submitting a user's form. The problem I have is that the first value is updated every time only. I see some 5 entries, I click the radio button for each entry and then submit the form. Only the first entry is updated. Other values ​​are not taken, maybe what is the problem?  
 Here's my jsp: "method =" post "& gt;  
  & lt; Portrait: renderURL var =" viewEmployeeDataURL "/>  < / Pre> 
 "result =" & lt;% = ListUtil.subList (employee appearance details, searchContainer.getStart (), searchContainer.getEnd ())% & gt; "/ & gt;    & lt; Liferai -i: search-container-column-text name = 'employee's name' value = '& lt;% = string.valouf (search .getEmpFname ()) + + "+ String.valueOf (search.getEmpLname ()) % & Gt; 'Href = "" / & gt; & Lt; Lifer-ui: search-container-column-jsp name = "presence status" path = "/ admin / radio button dice.jsp" align = "center" /> & Lt ;! - Get attendance comments for each employee - & gt; & Lt; Liferai -ui: search-container-column-jsp name = "presence reminders" path = "/ administrator / presence details.

 Appearance in jsp above. Details.Jesp only shows the "Comment" column from the database and radio buttonTipPail.JSP: "method =" post "& gt; current absent  < 
 
 
 
 
 
 When I submit the form, it goes to the Action class in each entry. Update it to?   
 
 
 I got an answer to my question. Objosuli This database was not related to any problem Was Or was it that I was not running on the prices. I was getting the value from the database and marking the attendance for each employee. The reason for the update of only one entry was due to the fact that only one Element.  
 I used a loop in my action class to iterate at all prices and now it works fine !!   

 











Google Appengine Java - Get EXIF data from Image -









        
 
 
 
 I have already searched a lot about it but I have found results for python only.  
 I am trying to get EXIF ​​data from an image, and give it output as a JSON, but as far as I understand that only Python is supported.  
 The first thing I should know is confirmation.  
 I found this  
 
 Java support still in the API is still necessary.   
 I have not found any other updates about this, is not yet supported in version 1.8.1.1?  
 There is a regular document for the method of extracting, but the method for Java does not exist. Another point to understand is that Java still is not supported  
 What I am actually trying to do, but my application is completely written in Java and I have a version for it the wanted.  
 Can you confirm that Java is still not supported to get EXIF ​​data from an image, and there is no way with third-party libraries, because Java ImageIO API by GAE Not supported?  
 Thanks guys!  
 
 
 You can use Python in the second version of your application and your Java version queue your Python The version can be used to target the EXIF ​​information that extracted and archives.

 I need a tooltip display at the top of the icon.  
 OK, I can fix  margin  by adding to the style of  tooltip  like:

 But, it could break other tooltip status.  
 How can I determine the  margin  without the style of ? Tooltip ?

android - notifyDataSetChanged with SQLite -









        
 
 
 
 I have a simple problem that I'm sorry to ask this, but I'm looking for a solution for hours Now I can not stand it.  
 My app is very easy. I've got "Working in a SQLite DB", and I populate with the DB to the list:  
  _dataAdapter = new function adapters (_c, _taskDAO.getTasks ()); _listTask.setAdapter (_dataAdapter);   
 gives an array of work list.  
 The problem is, when I click on the dialog to delete the task, it removes it from DB, but it is still on the screen, so I need to refresh the list view.  
  issue DialogInterface.BUTTON_NEUTRAL: _taskDAO.removeTask (1); _dataAdapter.notifyDataSetChanged (); break;   
 But this does not work, I think it is due to the fact that I am removing the work from DB but not with the adapter, but I am not completely sure. Anyway, if someone has a solution ...   
 
 
 If your adapter is an arrayaddetter or base adapter , The data is the source of your ListView, not just DB but the list you provide to the adapter.  
 You will need to update your adapter's datasheet (give it a new list) then call  
  _dataAdapter.notifyDataSetChanged ();   
 Another solution would be to recreate the adapter:

php - Getting delimiter from a line -









        
 
 
 
 Can someone tell me the best method in PHP to find a non-whitespace delimiter from a given line?  
 Some examples are:  
 Ex 1:  zone, do, abc@gmail.com, 996655   
 Ex 2: < Code> abc@gmail.com; the deer; ; 996655 <3:  zone # doe # 996655 # abc@gmail.com   
 Ex 4:  Joan Doe 96655 < / Code>  
 Ex 5:  Joan Doe 996655 abc@gmail.com   
 Ex 6:  zone; Doe; ABC @ Gmail Com, 996655;   
 In the above 4 and 5, it should be returned without a delimiter.  
 Any help is appreciated.  
 
 
 
 
 If email is on the last column, then email it The first letter should be found before (excluding white space)). Once it finds the four, then it should be checked whether any of these is not one-zA-Z0- 9. \ R \ n \ f   
     

 











asp.net - Check for empty value in C# - Webmatrix -









        
 
 
 
 I am creating an input field value where sometimes the value exists and sometimes I do not need to check it That's what the value is empty and will not show anything if it is not. Using my current code .IsNullOrEmpty:  
  & lt; Input id = "Lead-entry" class = "Forms text box" type = "text" size = "5" name = "q15_2013Collections [0] []" value = "@ (queryinputvalue.FirstOrDefault (r = & gt; r .field_name.Equals ( "q15_2013Collections [0] []")) field_data.IsNullOrEmpty "":.? queryinputvalue.FirstOrDefault (r = & gt; R.field_name.Equals ( "q15_2013 resolution [0] []"))) .field_data) "/>   
 Which gives me the error:  
  Exception Details: Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: can not be binding order for a null reference < / Code>  
 Thanks  
 Edit: This is the code I used to end:  
  Helpers.cshtml   
  checkEmpty (IEnumerable & LT; dynamic & gt; queryinputvalue, string FIELD_ID) @helper {var reqValue = queryinputvalue.FirstOrDefault (r = & gt; r.field_name.Equals (FIELD_ID)); Var return_value = ""; If (reqValue! = Null) {return_value = reqValue.field_data; } And {return_value = ""; } @ Return_value}   
  On page   
  @ {IEnumerable & lt; Dynamic & gt; Queryinputvalue = db.Query ("select * document_data WHERE doc_id = @ 0", doc_id); } & Lt; Input type = "text" class = "Forms text box" id = Name = "Q4_arborLoan" size = "20" value "INPUT_4" = "@ Helpers.checkEmpty (queryinputvalue," q4_arborLoan ")" / & gt;    
 
 
 Why are you doing this in  view ? You'll need to check these conditions controller to be written down to their  ViewModel :  
  public class ViewModel {public string QueryValue {get; Set ;.}}   
 and in your controller method you will simply populate this model and return it to the View page  
  public ActionResult MyMethod () { ViewModel Model = New View Modell (); // Get some value from anywhere String Recovery = some value. FirstOver Default (R => R. FieldName.quals ("q15_2013 resolution [0] []")); String query value = string Empty (); If (queryValues! = Null) {queryValue = string.IsNullOrEmpty (reqValue.field_data)? "": Recall. Field_data; } Model.QueryValue = queryValue; See Return (Model); }   
 Then, your view will be just type  
  @model     

 

c# - Alternative to using a ternary operator in Lambda -

Currently .. My code looks like this. Phone Numbers = x.PhoneGune First and last ()! = Null? PhoneNumber.firstOrDefault (). PhoneNumber: string.Empty,

PhoneNumbers a ICollection & lt; PhoneNumber & gt;

This is a , so I can not actually create a variable for it.

Resharper is complaining that x.PhoneNumbers.FirstOrDefault () can be zero, and to be honest, is not sold on the idea that let me do it twice The bar must be set to default first.

Any other idea, I am thinking that there can be another lambda method, I can do something like that.

  phone number = x.phone phone. Select (PN = & gt; pn.PhoneNumber) .FirstOrDefault () ?? "",    

 

javascript - jQuery: selectors not working over ajax downloaded page -

I am trying to extract an element from an AJAX download page so that later it can be added to the DOM. I'm getting the page like this:

  $ .ajax ({url: pagePath, success: function) {// data is shown correctly in debugger, all Elements exist. $ Div = $ (data) .find ("[data-custom-attr]"). First (); // $ (data) is length; 0, although the length of $ div is 0! // $ (Data) .find ("#jjpagepage") also has 0 length!}, Datatype: "html"});   
 This is the received page:  
    
 I have tried with some different selectors and everyone fails. I think there should be a really silly mistake somewhere in the code, but can not see it.  
 What is the problem with those selectors?   
 
 
 The reason for this is that jQuery throws all the nonsense given by you, and only H2 Parsing the div with:  
  $ ("> DOCTYPE html> gt; & lt; html & gt; & lt; head & gt; & lt; / head & gt; ; & Lt; body & gt; & lt; div id = 'ajaxpage' data-custom-attr = 'ajaxpage' & gt; & lt; h2 & gt; Ajax download page!  
    
   
 > $ ("& lt; div id = 'ajaxpage' data-custom-attr = ' Ajaxpage '& gt; h2 & gt; Ajax download page! & Lt; / h2 & gt; & lt; / div & gt; ")   
 ($ jQuery "...") floods Do not make document documents, it will only create dom pieces)  
 Because the first element is already your div, you have to be in the  [data-custom-entry]  subtree, So the result will be []. If you do  search ("H2")  then it will work fine, because it is in the subtitle of your div, but you  find  Can not div yourself

python - Query website(that requires login information) with input parameters and retrieve results -

I'm a Noah on this, so someone can tell me how to enter a website and fill out the form and get results Can be parsed in .csv For example, a website where you enter some parameters and return the server product that best matches your input parameters. I need to retrieve the list of products along with their specifications and parse them in .csv To do this, I need to select some buttons on the webpage that look like javascript objects. I tried the machine but it does not work for javascript objects I would love to post my query in Python. Thanks!

You have two options that I can think of:

1) Figure Find out that fields generated by Javascript are named, or have their naming schemes, and submit the value directly to the form handler - also eliminate the need to deal with the input page.

2) Use a framework that emulates a "real" browser and is able to process JavaScript. There are some suggestions for the framework, but have never used anybody, I can not give any suggestions to myself.

c++ - What is the difference between "Linux Kernel API", "System Calls", "System Interfaces" and "GNU C Library"? -

After trying to implement system call , I am fully confused about Linux: D

Linux kernel API , system call , system interface and GNU C library ?

Linux kernel API

Linux system call

System Interface

GNU C Library < P>

I am confused about these tasks.

For example sprintf is present in Linux kernel API , but this function is also included in the System Interface functions list Some functions should not be used in kernel mode (such as printf ). Many tasks do the same thing with different names (like sys_open and open ), and so on ...

My question is this Is: What is the difference between Linux kernel API , system call , system interface and GNU C library ? Which function should I use, which function should I not use?

Oh! C standard library : forgot

• C library C language applies the standard. This standard output is done by calling the operating-specific function, to ask to write. The C library can be applied to many more systems, such as Linux, Windows, DOS and various micro controllers.

  The term "GNU C Library" has probably been referred to with a special implementation C library, perhaps with the GNU Compiler Collection.

• The operating system displays a standard interface, in which system calls in Linux. So for example, writing standard output is done by calling writing system call. Linux (and more generally Pox) systems provide a C library around the call so they are convenient to use.

  You can apply the C library using this system interface. For example, the system call file can be applied with the code descriptor 1 to the putc from the c library.

  MS Windows provides an analog system API, which is called the Windows API, it can also be used to implement the C library.

• The kernel is programmed inside the API kernel, e.g. For drivers to write or provide new system calls.
  
  

preloading - Loading script before all images have been preloaded -

I am creating a gallery of images with thumbnail string below. I would like to pre-load these images so that when the user clicks on the thumbnail, the image will appear immediately. Although there are quite a few photos, so long as not being able to click on all the thumbnails, I do not want to wait until all images are loaded. While allowing the user to click on the thumbnail and display that picture, how do I allow images to be loaded in the background?

Here is the page for reference:

If you use jQuery for example You can do something like "," IMG.thumbnail ", function (event) {...});

This will enable handler for now or future with any selector.

For example

A : shelf controller : books , : movies and : Music .

Now I want to root it so I have tried it earlier: localhost: 3000 / shelf / books / new

  Resources: Books ,: Shelf => 'Books'   
 but they do not work.  
 At this time someone's help would be appreciated.  
 Thanks   
 
 
 Try something like that  
  Resources: do shelf resources: end of books   
 then you can do something  
  Resources: do shelf resources: books resources : Movies ... End   
 This will be the path to localhost: 3000 / shelf / books  Hope it helps!  
  Update  If you want all book resources under one shelf, then you can use a namespace

c++ - Creating a mutex class using Allegro mutexes -

मैं एलियग्रे म्यूटक्स (क्रॉस-प्लेटफॉर्म) पर आधारित कस्टम म्यूटक्स क्लास बनाने की कोशिश कर रहा हूं। मैं नहीं सी ++ 11 का उपयोग कर रहा हूँ मैं इसे ऐसा करने की कोशिश कर रहा हूं, लेकिन ऐसा लगता है कि यह थोड़ा ज़्यादा ज़रूरत नहीं है:

  टेम्पलेट & lt; class T & gt; क्लास म्यूट एक्स {निजी: ALLEGRO_MUTEX * mutex = NULL; ALLEGRO_THREAD * स्वामी = नल; टी * डेटा = नल; सार्वजनिक: म्यूटक्स (); म्यूटक्स (टी * डेटा); ~ म्यूटक्स (); बुल लॉक (ALLEGRO_THREAD * धागा); बुल अनलॉक (ALLEGRO_THREAD * धागा); बूल टॉललॉक (); // यदि आप थ्रेड बूल सेट (T * डेटा, ALLEGRO_THREAD * थ्रेड) को लॉक कर सकते हैं तो यह सही है; बूल प्राप्त (टी ** डेटा, ALLEGRO_THREAD * थ्रेड); // पॉइंटर के पास संदर्भ}   
 कन्स्ट्रक्शंस  al_create_mutex ()  को कॉल करेंगे और, दूसरे के मामले में, डेटा पॉइंटर सेट करें। विध्वंसक कॉल  al_destroy_mutex () ।  
 लॉक विधि यह देखने के लिए जांच जाएगी कि क्या  स्वामी  है  NULL  (mutex का संकेत खुला है और कोई धागा नहीं है)। यदि यह  NULL  है, तो यह  स्वामी = धागा  सेट करेगा और म्यूट एक्स लॉक करेगा। अनलॉक विधि,  धागा == स्वामी  और  स्वामी = नल  सेट करता है तो म्यूट एक्स अनलॉक करता है।  
 ट्रालालॉग विधि केवल यह देखने के लिए जांचता है कि क्या  स्वामी == NULL , यह इंगित करता है कि म्यूट एक्स को किसी भी थ्रेड से लॉक नहीं किया जाता है।  
  सेट  और  प्राप्त करें  पद्धतियां सेट और वापस लौटेगी संग्रहीत पॉइंटर, केवल तभी जब कॉलिंग थ्रेड लॉक किए गए म्यूटक्स का स्वामी हो।  
 मुझे लगता है कि जब भी आप किसी पद्धति को कॉल करना चाहते हैं, मैं पूरी तरह से थ्रेड के साथ थोड़ा सा पानी में जा रहा हूं, लेकिन मैं यह क्लास थ्रेड-सुरक्षित बनाने का कोई अन्य तरीका नहीं देख रहा हूं, क्योंकि एलियग्रे में  al_get_current_thread ()  फ़ंक्शन या ऐसा कुछ नहीं है मुझे इस वर्ग के साथ क्या करना चाहिए?   
 
 
 मैं दृढ़ता से सुझाव देता हूं कि आप एक ऐसा वर्ग बनाते हैं जो केवल अलैग्रो Mutex कार्यक्षमता, और कुछ नहीं करता है फिर एक अलग टेम्प्लेट क्लास बनाओ जो एक डेटा के लिए विशिष्ट एक्सेस प्रदान करने के लिए एक म्यूट एक्स का उपयोग करता है।  
  Mutex :: owner  के लिए आपकी एक्सेस डेटा दौड़ से बचने के लिए सिंक्रनाइज़ेशन की आवश्यकता है। यदि आप वास्तव में पुनरावर्ती और / या टॉकलॉक व्यवहार प्रदान करना चाहते हैं, तो ऐसा करें कि एक अलग कक्षा या कक्षाएं जो अपने कार्यान्वयन में अपने बुनियादी म्यूटक्स का उपयोग करते हैं (संकेत:  स्वामी  क्षेत्र की रक्षा के लिए एक म्यूटक्स का उपयोग करें और दूसरा ग्राहक को वास्तविक पारस्परिक बहिष्करण प्रदान करने के लिए)।  
 मुझे संदेह है कि  ALLEGRO_THREAD के बिना एक बुनियादी RAII आवरण  तर्क है कि वास्तव में आप वास्तव में समाप्त हो जाएगा।   

 

c# - How do you compile the precompiled in ASP.NET -

इस सवाल का पहले से ही एक उत्तर है: < / P>

• 6 उत्तर

  मुझे एक "पूर्वकम्पल्ड किया गया था "Asp.net ऐप स्रोत कोड ठीक है, मैं यह कैसे कर सकता हूं कि मैं इसका उपयोग और डीबग कर सकता हूं? मैं एक प्रीकंपाइल ऐप कैसे संकलित कर सकता हूं?

  

  इस विंडो की पिछली बार क्लिक करने के बाद, और मैं अनुप्रयोग बनाने की कोशिश करता हूं, मुझे एक त्रुटि मिलती है, जो कहते हैं," यह एप्लिकेशन पहले से ही प्रीकंपाइल है "।

  मैं क्या कर सकता हूँ?

  एक precompiled आवेदन पहले से ही यह कोड है (सी #) में संकलित DLLs। ASP.NET precompilation के साथ कुछ विकल्प हैं जो आपको साइट को अपडेट करने की इजाजत दे सकते हैं, लेकिन किसी भी पूर्ववर्ती संस्करण के साथ किसी भी सी # को बदलना मुश्किल होगा। यदि साइट "अपडेट करने योग्य" ध्वज को सही पर सेट किया गया था, तो आप .aspx (वेब ​​फ़ॉर्म) और .ascx (उपयोगकर्ता नियंत्रण) फ़ाइलों को अपडेट कर सकते हैं। आपको अपनी साइट पर दिखाने के लिए इन अपडेट्स के लिए पूर्ण बिल्ड बनाने की आवश्यकता नहीं है, बस उन्हें सहेजें और ब्राउज़र में देखें।

  यदि अपडेट करने योग्य को सही पर सेट नहीं किया गया है, तो इन फ़ाइलों में सभी को संकलित किया जाएगा DLL में और आप ऐसा नहीं कर सकते यदि आपको कोड को देखने और कुछ भी अपडेट करने की आवश्यकता नहीं है, तो यह पता लगाने का एक तरीका है कि प्रत्येक .aspx और .ascx को संकलित किया गया था और आप आगे की जांच के लिए प्रतिबिंब (। NET प्रतिक्षेपक या समान) का उपयोग कर सकते हैं।

  इसका कारण आपको त्रुटि मिलती है क्योंकि साइट पहले ही संकलित हो चुकी है और इसलिए उसे पुनः कंपाइल नहीं किया जा सकता है।

 और यहाँ मेरा प्रश्न है: लूप के निष्पादन के लिए नेस्टेड होने से पहले मुझे चर जेइनलाइज़ करने की आवश्यकता क्यों है? जब मैं ऐसा नहीं करता हूं, कोड को एक त्रुटि से संकलित किया गया है।  
 अग्रिम धन्यवाद।   
 
 
 आपको  j  को इनिशियलाइज़ करना है क्योंकि कंपाइलर को यह नहीं पता है कि यह अंतिम  में प्रवेश करने से पहले आंतरिक  के लिए  पाश में आरंभ होगा अगर  स्टेटमेंट  
 जहां तक ​​कंपाइलर का संबंध है, बाहरी  के लिए  लूप का निष्पादन निष्पादित नहीं किया जा सकता है।   

 

json - Can I serialize an interface(_recordset) with TJSONMarshal? -

I'm trying to serialize objects with TJSONMarshal (XE4), but when the goods _recordset

like

My class:

  TFoo = class private FrsFoo: _recordset; FFooProp: integer; Published asset rsFoo: _recordset Read FrsFoo FrsFoo; Property FooProp: Write FFooProp FFooProp Integer; End;

 Can I do this serial? Or a range of TJSONMarshal   
 
 
 In my case I just want to order _recordsets was my solution? :  
 1) get all _Recordset type fields:

perl - Interpolate in YAML -

I am using Perl as my scripting language and am reading YAML config. Files There are some fields (such as memory addresses) that are often used and are related to the base area. Is it possible to launch an anchor value and it is possible to do any work on it within the YAML file? I am using YAML :: XS as a parser module in Perl.

For example, in file.cfg.yml

 % YAML 1.1 --- Base: & amp; ; Base 10001000 - reg: - abc: * base + 4 ...   
 Is it possible to do any work on bin, oct, or hex values?   
 
 
 No, but you can sort actions as codes. If you can not control the input, the desiilizing code is actually silly idea. Take it and take it to heart.  
  Use YAML :: XS qw (dump); $ YAML :: XS :: Usakode = 1; #Danger Danger OMG You are doing that you are dancing or my $ base = 10001000; My $ data = [{base = & gt; $ Base},]; Push @ {$ data}, {reg = & gt; [{ABC = & gt; Sub {$ data-> [0] {base} + 4},}]}; Print dump $ d; __END__ --- - Base: 10001000 - reg: - abc: !! Perl / code | - {$$ data [0] {'base'} + 4; }

Any help greatly appreciated $ check = $ _POST ['template']; If ($ check == wrong) {echo 'thankyou.php'; } Else {echo 'error.php'; Mail ($ $, $ theme, $ body); }

If you want to redirect them to the page usage headers ("Location: thankyou .php "). If you want to use pages then it includes "thankyou.php";

.net - Avoiding concurrency issues with DbContext and Entity Framework -

I am creating ASP Web API project, which is using SQL Server for storage, and the unit To connect to the framework.

In many tables in storage there are unique obstacles to implement the specificity of values ​​in them. Before adding values ​​to these tables, to ensure that my prices are not present, my application check

This application has been created so that a DBCNode is present on every request. It has happened to me, however, two can try to include the same value in the request table. Request A checks the existence of the value of the table, as the request b does. Both have to find out that the value is required to be added, and add it to DBST. When called SaveChanges, a request will be successful, and failure will fail due to one.

How can these types of issues be resolved by the entity framework? I am planning to create stored procedures to retrieve or create prices, which I think should solve it (stored procedures that guarantee nuclear), but I completely solve it with unit framework To be installed in a way I think I'm dabantex. Save Changel () is called, but clearly stored procedure solution will mean that SaveChanges () will be done before executing the database.

This problem is not specific to the unit framework (although the EF certainly limits other boundaries around unique obstacles Too) This is common with any similar server client model. Since the specification will be applied to the database server at the time of the request, if no one tries to condemn, then unless you try to insert it, no idiots will be there.

He said, checking in advance for uniqueness should be a very cheap operation (on SQL Server, a unique barrier will also give you an index on that column), depending on whether How often do you expect to try the duplicate entry of the application, in your case on a large scale, but if it is too rare to start the efforts to put a duplicate, Inserting images can escape the round-trip and so be able to handle the exception.

There is no need to handle the exception is very complex, especially if there is no way to modify the data for the end user and try again. In this case, as you said, you are stopping many entries in a transaction, you may have to check exceptions (or internal exceptions) for specific obstruction names, so that you know which unit object is a duplicate . (Again, EF does not really support the handling of unique obstacle exceptions, so this is probably the part that is causing you the most pain yet.)

Note: < / Strong> do not recommend putting in the stored procedure only, who try to get duplicate entries concurrently for rare occasions. You're better off making sure your app handles this (and other SQL exceptions, many of which can be), as much as possible. However, if you feel that there is really no other way in your case, then a sproc can be the easiest way to do now. Just keep in mind that this is probably the most cautious code to solve a very rare case.

jquery - Having trouble adding a textfield every time a key is pressed in the previous textfield -

I have just started, but I really like using jquery and here on other questions easily Looking for the answer but now the IM stuck with it. I have currently set it to alert: Pressed, but when a key is pressed I have tried to use ended to add a text field, but I'm coming with errors.

It should add a new taxfile down to the original Texfield when a user enters the key.

Thanks in advance.

  & lt; Script src = "https://ajax.googleapis.com/ajax/libs/jquery/2.0.2/jquery.min.js"></script> & Lt; Input type = "text" name = "keydown" id = "keypress" /> & Lt; Script & gt; $ (Document) .ready (function () {$ ("# keypress") keydown (function () {warning ("pressed");});}); & Lt; / Script & gt;  
 
 Add a class to your current textbox, still use event delegation: < / P> 
  & lt; Input type = "text" name = "keydown" id = "keypress" class = "textboxpress" /> $ (Document) .ready (function () {$ (document) .on ('keydown', '.textboxpress', function () {$ (this) .after ("& lt; input type = 'text' class = 'Textboxpress' / & gt; ");});});   
 After the focused box it will add a new textbox. If you have a specific container that you want to add, replace  $ (this)  with your container selector and after   with  append
