wpf - Visual Tree Finder is returning null while searching for Data Grid -

I have a tab control in which there are several tab items, I calculate the data grid item while closing tab gates. For the first time it works fine (I mean walk first). After closing a tab item, DTG is zero in selling second frequency. Does anyone know why this is happening? I am in the subject that this UI is a problem, layout is not being refreshed. Please help me or show directions.

  while (tc.HasItems) {TabItem ti = tc.selectedItem TabItem; If (Tiwari == "Ð ?? Ñ ?? оÐ'Ð ° жР°") {Microsoft.Windows.Controls.DataGrid sellDtg = FindChild & lt; Microsoft.Windows.Controls.DataGrid & gt; (TC, "SellDataGrid"); If (sellDtg.Items.Count> gt; 0) {Sell sl = new Sell (); If (Sell.basketfromSellDateListBox == incorrect) {sl.ClearBasket (sellDtg); Sell.ClearFromSellBasket ((int) sellDtg.Tag); }}} If (TI! = Null) TC ITEMS. Rev. (TI); }   
 Thanks advance!  
  
 
 
 I did  LogicalTreeHelper  in a simple  analog for FindHildLogical The  function is written:  
  Public Fixed T FindChildLogical & lt; T & gt; (DependencyObject parent, string childName) where T: dependency object {if (parent == zero) returns to the return; Var kids = LogicalTreeHelper.FindLogicalNode (parent, childName); Return (t) children; }   
 And you say it in this form:  
  Microsoft.Windows.Controls.DataGrid sellDtg = FindChildLogical & lt; Microsoft.Windows.Controls.DataGrid & gt; (Ti, "SellDataGrid");   
 I hope you will be there where you want to.   

 

Outputing backslash in a C++ macro -

Is macro possible to write in C ++, which will return the after extension backslash?

I am currently using a code:

  # SOME_ENUM (XX) \ xX (first value), \ xX (second value), \ xX (some Other value = 50) \ XX (OneMoreValue, = 100) \   
 But I want to write a macro, which will generate the above code, so I want to be able to write:  
  ENUM_BEGIN (name) // It should be output: # DEFINE SOME_ENUM (XX) \ ENUM (ONE) // It should be output: XX (ONE,) \ // ...   
 but I'm not able to write a macro like  ENUM_BEGIN  Was it because it should finally expand to something with backslash, is it possible in C ++?   
 
 
 No, this is not possible. According to the translation phase 2, described in ISO / IEC 14882: 2011 (E), this will be § 2.2.1.  
 
 The example of each backslash character () is immediately removed after a new line character is removed, separating the physical source lines to create logical source lines. Only the last backslash on any physical source line will be eligible to be part of this kind of sacrifice. If, as a result, a character sequence that matches the syntax of a universal-character-name, is produced, behavior is undefined. A source file that is not blank and that does not end in a new-line character, or that ends immediately after a backslash character of such type of partition that ends in the character of a new line, processed it As if an additional new line line was added to the file.   
 What will be actually  \\\ n  (where  \ n  is physically in the source, not an escape) Will be considered as a  \  character, followed by a line benzene, the remaining  \  can be in a syntax error (there may be situations where it is legal , But I no longer see it in any way), and during the subsequent translation steps the line is not treated as benzene (line different There is only a step # 2).   

 

image - Is there a equivalent of Android's BitmapFactory.Options isDecodeBounds for TIFF in Java/JAI? -

I am trying to improve the performance of my system (a Java app running in Tomcat) and now a barrier In operation, we need the dimensions of TIFF images to read and read, so we use the JSD ImageDecoder and ImageDecoder decoder = ImageCodec.createImageDecoder ("TIFF", input, The ultimate); RenderedImage r = decoder.decodeAsRenderedImage (); Int width = r.getWidth (); Int height = r.getHeight ();

By sampling data, much time is spent in createImageDecoder. My assumption (without going to ImageCodec's source code) is it possibly trying to decode input stream

Coming from Android land, I'm hoping that BitmapFactory.Options Similar to the installation of .inJustDecodeBounds = true , there is a solution similar to the direct explanation, but there is no luck finding any other library so far. (I know that hard support on Android is missing in AOP, but it is a matter of another day.)

Anybody knows this library which does this? Or is there any way to achieve the same goal of using Jai / IdiIio?

It seems that the groups of this information together in a title, so that you Can read:

  Private static dimensions getTiffDimensions (InputStream tiffFile) throws IOException {readableByteChannel channel = Channels.newChannel (tiffFile); Bytebuff buffer = Bytebuffer.Olock (12); Balrade (channel, buffer, 8); Byte endian = buffer.get (); If (endian! = Buffer.get () || (endian! = 'I' and endian! = 'M')) (new iOxation ("not a quarrel file.");} Buffer.scer (endian == ' I '? Byteorder. LittelIne: Byteorder. BigADIN; if (buffer.Tet!) = 42) {New IOXation ("No Tiff File."); } // Go to the first image directory. Note that we have already read 8 bytes. TiffFile.skip (buffer.getInt () - 8); Int width = -1; Intensity height = -1; // The first two byte fields of IFD are the number of bytes. Balrade (channel, buffer, 2); (At field count = buffer.Tet (); field count & gt; 0 & amp; amp; amp; amp; amp; amp; amp; amp; amp; & amp; (width & lt; 0 height & lt; 0); -fieldcode) {forceRead (Channel, buffer, 12); Switch (buffer.at ()) {case 0x0100: // image width width = refill (buffer); break; Case 0x0101: // image "length", height of height = reading field (buffer); break; }} Return new dimensions (width, height); } Private stationary zero force reads (readable channel channel, byte buffer buffer, int n) throws IOException {buffer. (0); Buffer.limit (n); While (buffer HSrmaning ()) {channel.read (buffer); } Buffer. Flip (); } Private Static Integrated Field (byte buffer buffer) {int type = buffer.getShort (); Int count = buffer.getInt (); If (calculation! = 1) {new runtime expedition ("expected to count 1 for given field."); } Switch (type) {case 3: // word reffer buffer.tat (); Case 4: // Int Refer Buffer.GetInt (); Default: // char (not used here) Return buffer. Gate () & amp; 0xFF; }}   
 I tested it with some different quarrel files (black and white color with transit, encoded length) and it works fine. Depending on the layout of your TIFF file, it needs to read a lot of streams before getting the size (one of the previously tested files, saved from Apple's preview, at the end of the file was this) Could.   

 

Generating really big Java code -

I have to fill ~ 20k underlying function and constant with a list of CHM files. First of all I tried to list them, but deserialization takes 1500ms (too early to get code-complete, even on the first hit).

Tried the code generation using string templates, which generates valid code. But this will not compile because the "initEnums () method exceeds the size limit of 65536" (and my eclipse ends soon)

The generated method looks like this:

  Public XModelField [] initEnums () {New XModelField {New XModelField ("Aname", "aType", ...), ... // approximately 4'000 more entries}; }   
 If this limit is limited to source code, then I can use another library to generate a class file (maybe codemodel) directly. I would like to keep my code, if possible, any suggestions without rewriting the output generator again from scratch?   
 
 
 I think you should reconsider your strategy, model your data structures and methods accordingly and You do not need to generate code. Instead of generating Java code for 4000 constants, store your data in a file or database and write that data to read that data in the initial time to fill a list with your data object.  
 Generating code is a powerful tool, but you should use it carefully. I do not think it is also necessary for your use case, but if you think that this is it, you can try to reduce the portion of the code so that to keep things simple, there is a minimum minimum Possible. Often you can extract a lot of generic codes in an intangible superclass so that you only have to code for some methods in subclasses. And generating codes for 4000 constants is really unnecessary, keep the data in the form of data and dynamically work on your data.   

 

backbone.js - Should all Backbone on/off events be replaced with listenTo/stopListening? -

जहां तक ​​मैं बताता हूं, listenTo और stopListening क्रमशः पर और बंद को बदलना चाहिए। क्या मैं सही ढंग से समझता हूं? क्या listenTo / stopListening के बजाय पर बंद का उपयोग किया जाना चाहिए, जहां कोई भी स्थिति है < P> संपादित करें:

जैसा कि मैंने अपने कोड को रिफैक्टर चलाया, यह स्पष्ट हो गया कि पर के लिए कुछ कोड हैं listenTo । यह बहुत स्पष्ट है कि जब एक ऑब्जेक्ट अन्य ऑब्जेक्ट को सुनता है:

एक ऑब्जेक्ट को किसी विशेष घटना को अन्य ऑब्जेक्ट।

इसलिए, जब कोई संग्रह या मॉडल एक घटना को अपने आप सुन रहा है, तो हमें listento के बजाय पर

मान लें कि मुझे यह सही है ...

listenTo और stopListening राज्य का ट्रैक रखें यह थोड़ी सी कोड ओवरहेड की लागत पर आपके लिए सफाई का ख्याल रखेगा। बस के बारे में हर मामले में मैं सोच सकता हूँ कि आप अपने विचारों के लिए यह व्यवहार चाहते हैं, लेकिन आप खुद को / बंद कॉल को संभालने के लिए गलती नहीं करेंगे; वे को और बंद किसी भी समय जल्द ही नापसंद करेंगे।



PHP, regex, and capitalization -

But this Preg_replace (and I do not think it helps in changing the case in a backfirst) Suggestion: < P>

You can use it like this:

  $ string = Preg_replace_callback ('# (? & Lt) ; = -) (.) # ', Create_function (' $ matches', 'return strtoupper ($ matches [1]);', $ string);   
 Or, with an anonymous function (using PHP ver> gt; = 5.3.0):

resources - Java closing/cleaning up -

I have a class in which there are some large objects:

  public class MyClass { BigObject bo; Public MyClass () {...}}   
 Should I make a close approach like the following:  
  public zero-off () {bo = Null; }   
 I think this is good for garbage collection (?) Am I on the right track? How should I go for cleaning this class?  
 
 
 I think this is good for garbage collection   
 No, it just masers the code.  
 What is the catchover of the example of MyClass ? If you need an example of  MyClass  to stay alive but is not  Big Object  then - and only then - can you  BO  Setting should be bothering zero But at the same time, you should consider your design. Generally, all states of one class are important for its lifetime. There are exceptions to that rule, but they are relatively rare.  
 When the example of  MyClass  is eligible for garbage collection, its  BO  variable will be irrelevant to whether the  BigObject Example of  is eligible for garbage collection, so it does not matter if it is not empty or not ... but it  does  clean up after you manually To try, write a large difference in the context of the  not  code. They may have.  
 You should clear resources such as currents, country handles etc. - but usually you can handle the garbage collector with the memory.   

 

Creating a startup daemon for a shell script in FreeBSD -

I am trying to create a file in rc.d / which I wrote a / bin / sh script initially Will do it. I've followed some examples found here:

  #! / Bin / sh -x # Available: copyfiles /etc/rc.subr name = copyfiles rcvar = copyfiles_enable pidfile = "/ var / run / $ {name} .pid" command = "/ var / etc / copy_dat_files.sh -f /var/etc/copydatafiles.conf "command_orge =" & amp; " Load_rc_config $ name run_rc_command "$ 1"   
 It seems that I have a problem with the PDF file, should my script be one that creates a PID file, or is it automatically Is made from? I have tried both ways, and whether I make my script a PID file or not, I get an error that the PID file is not readable  
 if my script is about to make it , Then what is the correct way to create a PID file?  
 Thanks   
 
 
 For example, look at existing daemons (like / etc / rc .d / mountd). Then look at the sub-routine in /etc/rc.subr - there is a code to see the PID-file but nothing creates it.  
 In other words, you can declare the daemon-initially the script, the pid-file, but by making it depend on the daemon, speaking of daemon, you use daemon (8) utility If your demon is actually a shell script, utility will take care of creating a PID-file for you (if you have been typed in daemon C, you can use the daemon (3) function.)  
 BTW, Mary In health, even during the opening of the demons, PID-files, Em> Lock  with them (the flock (3) or Fsiantiel (2) or Lokf (3)). In this way, if there is an instance crash (or killed) without removing the PID-file, then there will be no problem determining the next instance, the file is stale.

 And my download activation, where I try to get it:  
  ArrayList & lt; MetaDados & gt; Fulllist = (arrelisted & lt; metadando & gt;) getIntent (). GetParcelableExtra ("Metadascusful"); (Metadado Metadados: FullList) for {Log D.

GetParcelableExtra ("Metadosporters"); (Log D. for Metadados Metadado: Prestist) (Constants.DOWNLOAD_SELECTED_ACTIVITY, MetadataGetname ()); }    
 
 
 Use Intent.putParcelableArrayListExtra () instead of putExtra (), and getParcelableArrayListExtra ( ) Instead of getParcelableExtra () you can also lose the stopper, so that's where it's flying.

facebook graph api - FQL does not return all news feeds -

I used FQL to retrieve all my news feeds (as recently as 50 or 30-day documents) I am using. However, I can not get back only a few feeds for the past 30 days, is there any one problem? I use FQL to retrieve feeds:

  from SELECT filter_key in SELECT filter_key with stream WHERE filter_key created_time, updated_time, message, attachment, preferences, where shared number UID = me () and created_time & lt; = Now ()   
 In addition, I have read that the graph API returns more results than FQL. I read some graph API examples, but do not understand what my query looks like if I want to just list the photos posted on my news feed?   
 
 
 I will start with easy:  
 to return only the posts There are photos, add  and type = 247  in the  WHERE  section of your query, this is something that you can not do with the graph API.  
 For other questions you have, the  stream  is one of the toughest of the queries for the table and the result you want.  
 To not get enough results, the internal boundaries of Facebook do not work as an advertisement in my internal experience. If you explicitly request for many posts by adding  LIMIT 100  at the end of your query, then you can usually get close to the actual number of items you expected.  
 The Facebook filtering algorithm works on your results  followed by  queries, so you can view on your newsfeed within the Facebook web app, ending with so few posts May be. It must be done with your friends having privacy settings enabled. And no, there is no way of testing for them.

 < Code> import StringIO f = StringIO.StringIO () # Create an object like a file wbk = xlwt.Workbook () earnings_tab = wbk .add_sheet ('Earnings') wbk.save (f) # write stdout   
 Some suggestions might be given that  StringIO  instead of  cStringIO , but in the former Please note that  cStringIO  when I last checked that Unicode is not properly handled  
 It is also worth noting that  StringIO  has been changed to  io  in Python 3.   

 

Combining two regular expressions in boost regex -

I have two regular expressions that look at the URL and determine that the URL is a watchlite video URL

1. The URL should contain at least one of these extensions, where .isma, .ismv, .isml

   Regex: .ism (a | v | l) < / P>

   1. URL "string" / quality level ({bitrate) / pieces (audio = {start-time} ) Should be "

      Regex: / quality level (\ d +) / pieces (\ b (o) Dio | Video | Text) \ b = \ d +)

      How do I add these two stars in one and ensure that both the conditions are satisfied?

        is_silverlight_livestream_url (const char * url) {/ * * xxx.isml / QualityLevels (& lt; bitrate & gt;) / pieces ( = & lt; timecode & Gt;) "* On-demand stream has an extension" .isml "* / static boost :: regex regex (my_regex_str); Try (if (boost :: regex_match (url, regex) == true) {back to true ;}} Hold (std :: runtime_error e) {} return false;}   
       satisfaction   
       
       
       You have to do something where you search for a string, after that (optional) additional characters (you can be more specific if you know that this How to see the URL) and then file extension at the end:  
        / quality (\ D +) / pieces (\ b (audio | video | text) \ b = \ d + ) (. +?)?. Ism (a | v | l)

see - & gt; Property Manager, then use a property sheet for that build configuration to expand a project and create the configuration. Right-click on the property sheet and select Properties to modify the property sheet. I do not recommend modifying the underlying asset sheet, although for this purpose there is a .user property sheet. You can also create your own property sheet that defines a preprocessor macro, then add your new property sheet to the list for each build configuration.

sql - Is it possible to rollback create_all in sqlalchemy? -

According to the question for some DBMS, it is possible that it is possible to prepare rollback table statements. Especially it is possible for SQLite (although it is undocumented).

So my question is, is it possible to rollback everyone in sub-section? I was trying to write some test codes, but it does not look like:

  & gt; & Gt; & Gt; Engine = Creating_Agin ('sqlite: ///: Memory:') & gt; & Gt; & Gt; Engine engine (sqlite: ///: memory :) & gt; & Gt; & Gt; Session = session maker (bind = engine) & gt; & Gt; & Gt; Connection = engine.connect ()> gt; & Gt; & Gt; Session = session (dam = connection) & gt; & Gt; & Gt; Engine.table_names () []> & Gt; & Gt; Transaction = connection.begin () & gt; & Gt; & Gt; Base = declarative_base ()> gt; & Gt; & Gt; Class test (base): ... __tablename__ = 'test' ... id = column (integer, primary_key = true) ... & gt; & Gt; & Gt; Base.metadata.bind = Engine & gt; & Gt; & Gt; Base.metadata.create_all () & gt; & Gt; & Gt; Engine.table_names () [u'TEST '] & gt; & Gt; & Gt; Transaction.rollback ()> gt; & Gt; & Gt; Session.close () & gt; & Gt; & Gt; Connection.close () & gt; & Gt; & Gt;  
 
 Use Postgresql or SQL Server MySQL supports DDL for Oracle  not  transaction Although recent versions of SQLite have DDL support of transactions Python.   
 
 Simple recipe:  
 with  engine. (Like) conn: metadata.create_all (conn)   
 If you increase an exception inside "with:", the transaction will be brought back.   
 
 Want to see it yourself, okay:   to inspect sqlalchemy import from  need to run 0.8 with the engine is. Conn: trans = conn.begin () metadata.create_all (conn) inspector = inspection (conn) table_names = to gain an understanding of the transactional scope, inspector.gate_table_name () trans. Rollback () inspector = inspection (con) rolled_back_table_names = inspector.get_table_names ()

How to display all columns associated with duplicate emails in SQL server 2008 -

I did some research on finding a way to filter duplicate emails, so all the columns connected to these duplicate emails But I can not find any answer to help me with it.

I have currently pulled the data using the following code:

  Select Email, COUNT (email) AS email from dup_count [cem_farmers_masterinvitelist]. [Dbo]. Email by email (Email)> 1) Order by email   
 This gives me the  xxxxxx  amount of rows I then pull any data (column) I want to be able to connect to these duplicate emails - and only duplicate.  
  SELECT * FROM [marks_party_MasterInvite] [Dbo]. [Invitation list] Where in the email (select [marks_party_MasterInvite] by email. [Dbo]. [InviteList] Email hosting COUNT (email)> 1)   
 I know that I'm doing something wrong, because  
 thanks guys,  
 post -text itemprop = "text"> 
 you window functions Want to use. The following combines the count in each row, then you can use a  where to get all the columns  filter:  
  SELECT il. * FROM (select IL *, count (*) over (via email partitions) as [cem_farmers_masterinvitelist] to cnt. [Dbo]. Inverted list) IL where CNT & gt; 1 order by email does not count   
, because when you receive each line, you are going to get a duplicate in the first query, you are getting specific emails.   

 

Regex for Valid Email address or Valid alpha numeric check -

Hello, I have a field named Username in my MVC 3 model. This proposal may be a valid email address or be valid alphanumeric. How can I write Reggae Express to check both things (valid email or valid alpha numeric)

The valid email expression I am using

  "^ [_ _A-zA -Z0-9 \ '-] (\ [_ one-zA-Z0 -9 \. '-]) * @ [one-zA-Z0-9 -.] + (\ [One-zA-Z0-9 -] +) *. (([0-9] {1,3 }} | ([A-zA-Z] {2,3}) | (name)) $ "  assuming that instead of an email address you want to match the alphanumeric string, It's actually just  AZ  
 
 
 0-9 , which you already have Only you can take ...  
  ^ [_ a-zA-Z0- 9 \ '-] + (\. [_a-zA-Z0-9 \' -]) * @ [One-zA-Z0-9 -] (\ [one-zA-Z0-9 - ..] +) * (([0-9] {1,3}) | ([a-zA-Z ] {2,3}) | (name)] $   
 ... and wrap it in a bracket with a pipe to indicate it as an optional group ...  
  ^ ([_ a-zA-Z0 -9 \ '-] + (\. [_A-zA-Z0-9 \' -] +) * @ [one-zA-Z0-9 -] (\ [one-zA-Z0-9 -]) * \ (([0-9] {1,3} ..) | ([A-GA-Z] {2,3}) | (name) | [A-GA-Z0-9] +) $   
 Which looks like a very simplified solution, give that which you have done so far, which makes me wonder if there is something on it ???   

 

perl - regex with variable part -

How can I merge these 2 regex into a single regex string string (all available on the basis of the last 3 fields Captures parts) are optional in $ s and they should be captured if they exist)? I could not find any work solution using (? = ...)

  $ s = '1.2.3.4 - Example [10 / Dec / 2007: 21: 07: 20 +0100] "GET /x.htm HTTP / 1.1" 401 488'; $ Re = qr / \ A (\ d +) \. (\ D +) \. (\ D +) \. (\ D +) [] (\ S +) [] (\ S +) [] + \ [(\ d +) \ / (\ S +) \ / (\ d +): (\ d +): (\ D +): (\ d +) [] (\ S +) \] [] "(\ S +) [] (. *?) [] (\ S +)" [] (\ S +) [] (\ S +) \ z / x; Print "[" .join ('], [', $ s = ~ $ re]. "] \ N \ n"; $ S = '1.2.3.4 - - [13 / Jun / 2007: 01: 37: 44 +0200] "GET /x.htm HTTP / 1.0" 404 283 "-" "Mozilla / 5.0 ..." "- '; $ Re = qr / \ A (\ d +) \. (\ D +) \. (\ D +) \. (\ D +) [] (\ S +) [] (\ S +) [] + \ [(\ d +) \ / (\ S +) \ / (\ d +): (\ D +): (\ d +): (\ d +) [] (\ S +) \] [] "(\ S +) [] (. *?) [] (\ S + ) "[] (\ S +) [] (\ S +) []" (. *) "[]" (. *?) "[]" (. *?) "\ Z / x; print" [".join ('], [', $ s = ~ $ re].]] \ N \ n";    
 
 
 a lookahead  (? =)  You can match a non-capturing group  (?)  and zero or an event Are:    $ re = qr / \ a (\ d +) \. (\ D +) \. (\ D +) \. (\ D +) [] (\ S +) [] (\ S +) [] + \ [(\ d +) \ / (\ S +) \ / (\ d +): (\ D +): (\ d +) [] (\ S +) \] [] "(\ 'S) [] (. *?) [] (\ S +)" [] (\ S +) [] (\ S +) (?: [] "(. *?)" [ ] ". (? *)?" [] "(. *?)") ?? Z / X;   
 This will capture fixed-range boundaries of captures, but if the optional capture If the group does not match, then the last 3 eggs will be if you want to match between 1 and 3 optional fields, then each of your non-capturing groups has zero or more (? ) I also tried to do this, but it does not work:  
  (?: [] "(. *?)") {0}}   
 It matches and occupies each of the previous three areas, but each capture caption overwrites the last position in the capture array, so after capturing it only The final area is there.  
 Be careful that you are using a very strict expression that may not be suitable for all web logs: in particular, the IP address will not handle the IPv6 address for the IP address, and Based on the user agent for match user agents, the   characters, how they survive (lighttpd 1.4.28, for example, does not save them).

using map in python 3 -

Hi This code works on Python 2.7, but not in Python 3

  import Itertools def product (a, b): return map (list, iterolol. Product (a, repeat = b) print (sorted (product ({0,1}, 3)))   
 It outputs  
  [[0, 0], [0, 0, 1], [0, 1, 0], [0, 1, 1] , [1, 0, 0] in Python 2.7, [1, 0, 1], [1, 1, 0], [1, 1, 1]]   
 but Python 3 It gives a map object at 0x028DB2F0, anyone know how it works for Python 3 So that the output should remain similar to Python 2.7.   
 
 
 Just wrap it with a list:   itertools def product (a, b): return list (map, list, itertools.product (a, repeat = b)) print (sorted (product ({0,1}, 3)))   
 Find more  
 In two words in Python 3 map  
 
 Return an Iterator, which works in every object Implemented, provides results.   
 In Python 2.7,  
 
 Apply the job of every object and return a list of results.    

 

IOS In App Purchase: can I let the user buy again same product? -

To successfully follow the guidance of some of the IAP tutorials for iOS, such as:

> My problem is that: I want the user to buy the same product he has already bought - is this possible on the consumable method? (I am searching for 2 days for an answer for this, and so far nothing.)

The target user has to buy from hundreds of products of the product (hence I do not want to make it. There are hundreds of product identifiers, so I'm using the same product ID for all products and internally support internal products (as far as Apple knows that using She has bought the same product again ...))

Thank you in advance ...

"post-text" itemprop = "text">

OK After spending some time about this issue - I just realized that this is not an issue: Apparently Apple does not ask for an Apple ID or password if you buy the item immediately after the first purchase.

You know what it means (actually you know - I did not:)), I will keep my son away from my son after buying something from now ...) / P>

c# - Input text control disappears on postback -

I have some input controls (text) that have been created as part of the code-behind such a dynamic radiobutanist (So ​​that a textbox is next to Radiobootton):

  Radio button list radiooption = new radio button list (); Radiobuttonlist.Items.Add (new listing ITM (DT.ROS [I] [9] .restring () + "input id = \" + + + name + "\" runat = \ "server \" type = \   
 All controls are within the update panel.  
 Every time there is a postback, " Text within the input  
 Any thoughts? Very much appreciated!   
 
 
 control tree Must be rebuilt on  every  postback, in which partial postbay - or allow it to be regenerated through the controlstate / viewstate. In this case, in the later postback  
 For such cases, I will contact it like this:  
 
 Enable ViewStat on the radio button list  and  make sure it does not add more than load  1 , or  
 Container control Store a viewstate of a proper collection on it and then the consumer databa Nd G control - to set it see a clear way. I like this approach because it is consistent, easy to predict and control.    
  1  it  should  work but it probably is not. I am generally confused about which control  actually  supports the viewstate, and to what extent does the use kill me as usual .. Incompatible. In any case, this   will not be  will not  - remember that disabling the viewstrate for page (or parent control) disables ViewState all the way down Additionally,  and  should control  and  in the control with the same control path / id (usually init or load) in order to ensure that it works correctly.  
 
 Any ideas for # 2:  
 Save the visual control in that user control (this control should be vestostat enabled):  < Pre>  // ListItem is a proper serial and // works well for automatic binding for various list controls. & Lt; ListItem & gt; Name {// May receive return tap {return (list & lt; ListItem & gt;) ViewState ["name"]; } Set {ViewState ["name"] = Value; }}   
 In the GenericDataSourceControl (if it is a good id, put the GDS in the markup) Select the event:  
  Zero SelectEvent (Sender E, GenericSelectArgs Args) {args.SetData (name); }   
 Dynamically add a radio button list (say, in  Control.OnLoad ):  
  // Unless it Do not need to be dynamic, move it into declarative markup // dynamic control * should be added to the same place * it was before // postback or ugly invalid control tree construction will be exceptions. Var radio list = new radio button list ; SomeControl.Controls.Add (radioList); // This should be unusual for reducing the problem of making the control tree and // should be consistent for the dynamic control. Radio list.id = "radio list"; // The binding for DS "declarative" usually works better I've got a radio list. DataSourceID = "idOfTheGDS"; // You - Databank is required based on certain factors - I will usually call Databank in the prerenders, but generally the load is fine / liked. // If it already binds, do not call it manually radioList.DataBind ();   
 If databanding is working correctly, it is possible for the radio button to disable  disable  viewstate. But occasionally the use of the viewtest When the controlstate was supposed to be done, so make sure it works as desired.   

 

java - Recalling an Int from a method? -

I need to return an int to use 4 random fraction points (any repeated) for the main method so that I can not use string methods for the rest of my work. I want to print it random number.

It is what I have:

  public static zero main (string [] args) {int generatedSecretNumber; System.out.print ("Random number is:" + software generated;); } Public static int generateSecretNumber (int w, int x, int y, int z, int secretNumber) {random race = new random (); W = ran.nextInt (); X = Run Next (); Y = ran. NnextInt (); Z = ran.nextInt (); While (w == x || w == y || w == z) {w = ran.exit (); } While (x == w || x == y || x == z) {x = ran.nextInt (); } While (y == w || y == x || y == z) {y = Run. Nxit (); } While (z == w || z == x || z == y) {z = ran.exit (); } If (w! = X & x! = Y & y! = Z) {secretNumber = w + x + y + z; } Secret return number; }}    
 
 
 In your code, you really never have your  generSecretNumber Calling ()  Method, you're declaring a variable then instead. Remove the announcement in your head, and change the printing line to  System.out.print ("random number is:" + created number ("++"); .  
 Next, Code> generateSecretNumber ()  must not have any argument in the method, because it determines what it is going to do entirely on its own, and no external data is required because logic remains , You need to declare it as  int w, x, y, z; .  
 Other , You are generating a random integer without the upper bound is not exactly what you want, instead, your upper limit for  rand.nextInt ()  calls must be 10, resulting in  Rand.nextInt (10) . It can choose a random integer anywhere from 0 to 9.  
 And finally, you return the amount of digits instead of the actual four digit number Instead, return the sum of each of their points to their place For example, the fourth digit should be  w * 1000 .  
 Example of the result:  
  public class RandUniqueFourDigits {public static zero major (String) [] Args) {System.out.println ("Random number is:" + Creator number ()); } Public static int generateSecretNumber () {random rand = new random (); Int w = 0, x = 0, y = 0, z = 0; // generate each digit until all of them are unique (w == x || w == y || w == z || x == y || x == z || y == z) { W = Rand.nextInt (10); X = rand.nextInt (10); Y = RAND Xxit (10); Z = rand.nextInt (10); } // Generate each digit until they are all exclusive = rand.nextInt (10); Do x = rand.nextInt (10); While (x == w) // add them to an integer and return return w * 1000 + x * 100 + y * 10 + z; }}   
 for a more efficient loop (each number is reproduced only when your initial code should be resized), this time with a completely loop Replace:    w = Rand NXIT (10); Do x = rand.nextInt (10); Whereas (x == w); Do y = rand.nextInt (10); Whereas (y == w || y == x); Do z = rand.nextInt (10); While (z == w || z == x || z == y); Results in   
:  
  public class RandUniqueFourDigits {public static zero major (string [] args) {System.out.println (GenerateSecretNumber ()); } Public static int generateSecretNumber () {random rand = new random (); Int w = 0, x = 0, y = 0, z = 0; // Generate each digit until they are all exclusive = rand.nextInt (10); Do x = rand.nextInt (10); Whereas (x == w); Do y = rand.nextInt (10); Whereas (y == w || y == x); Do z = rand.nextInt (10); While (z == w || z == x || z == y); // Give them an integer and return return w * 1000 + x * 100 + y * 10 + z; }}    

 

c - Having trouble using if statement with for loop and arrays -

I have a problem in one of my tasks here is the code:

  included & Lt; Stdio.h & gt; Include & lt; Math.h> Include & lt; Stdlib.h & gt; Int inputount (int i); Zero input (double data [], int j); Double Fartole (double data [], int j); Zero output fahr (double data [], int nuffar); Zero Output Allowed (Double Data [], Intimate Nuffarrs); Zero Output Highlight (Double Data [], Int Newfahar); Zero Outputgrad (double data [], int NFhurs); Int main (zero) {int i, j, numfahrs; Double data [i], * ptr = & amp; Data [i]; I = inputAmount (i); Printf ("% d \ n \ n", i); InputFairers (and data [i], i); Data [j] = fartosel (and data [i], j); Printf ("% 1f", data [j]); Return 0; } Int inputAmount (int i) {printf ("Please enter the amount of quantities to be used. \ N \ n"); Scanf ("% d", & amp; i); While (i and lt; 1 || i> 25) {printf ("Value is out of range, please enter other values. \ N \ n"); Scanf ("% d", & amp; i); } Came back; } Zero inputfrom (double data [], int i) {int j; Printf ("Enter the temperature values ​​in the range of -175 to 175 degrees F. \ n \ n"); For (j = 0; j  175} {printf ("the price of the temperature is out of range. Please re-enter"); Scanf ("% F", and data [ja]); }}} Double Fertosel (double data [], int j) {int i; Printf ("test"); {Data {i] = (((data (i)) - 32) * (5.0 / 9.0) for (J = 1; J & lt; = I; J ++); } Return figure [i]; }   
 Basically the issue in my code is that if I leave this code entirely  if  leave the statement I want to go to the program  loop and If the user enters the value outside a certain range, then I want the  if  statement to start a statement  inside a loop, but a statement of statement in the statement  if  If there is something wrong with it then I can replace the location of  if   has also tried  to loop   
 
 
 The problem is that you  
 
 i   
 j Using a subscript will work  
 
 scanf ("% f", and data [j])  
 if (data [j]  175)   
 should work because the data [i] is not a possible subcript value, because I have the array size  
 and why you use the line Have done  
  data [i] = data [i];   
?

 Have you tried to use some index to speed up your query? I also propose to use a prepared and parameter query because it is too heavy to generate new commands in the loop.  
 In addition, from my experience, the SQLite database becomes very slow when there are many rows in it. We used to clean the SQLite database of old data, we used to store it in another database  
 BTW, MS SQL Server CE (this is an embedded in-cock database, no setup required) only Behaves very accurately when there are so many data in the table We have used the Windows service as a caching database, which has been dealt with by thousands of clients. When the size of the database exceeds 1 GB, it starts slowing down.

java - whats wrong with this code? -

For some reasons I keep anything blank which I keep in empty lines, I try to create a program I'm reading the input, removes all the unnecessary white spaces but a place between each word. Then print all the lines

  import java.util.Scanner;  
 Do not use any sentinels to close. Import java.lang.Character; Import java.lang.String; Public class trim {public static zero main (string [] args) {string namename = ""; String sound = ""; Int i = 0; Int count = 0; Scanner scan = new scanner (System.in); While (scan.hasNextLine ()) {count ++; Scan.nextLine (); }; (; I    
 
 
  while (scan.hasNextLine ()) {count ++; Scan.nextLine (); }   
 This will also read all the inputs before your program actually starts.  
 After that (if the program also goes away, STDIN usually does not lock on the console) There is nothing else to read in the second loop in the scan.  
 In addition, the names of lower-case class are confused as upper-case variable names. At least you are consistent here; -)

paperjs - Hit test with a radius on a point -

The following code in the paper.js structure performs a hit at the point of coordinate of mouse coordination. Function OnMouseUp (Events) {var hitOptions = {Stroke: Wrong, Fill: Correct, Tolerance: 2}; Var hitResult = project.hitTest (event.point, hitOptions); }

I want to do this that I have to do this exam within the given radius of event.point (), but I have not found any way yet.

Any thoughts?

UPDATE

I think the way I was setting the option should be ignored. The following code works:

  var hitOptions = {fill: true, stroke: true, Segment: true, tolerance: 200}; Var hitResult = project.hitTest (event.point, hitOptions); Alert (hitResult);  
 
 It seems that due to a bug the tolerance option is not read. You can manually change the tolerance by modifying the line 3631 (at night). For example, if you want a test radius of 200 points:  
  Tolerance: paper.project.options.hitTolerance || 2   
 to:  
  Tolerance: paper.project.options.hitTolerance || 200

jquery - having trouble convert getJSON data to model -

I can not seem to be working knockout when I get the storage from getJSON. Here is an example of my code

  function MyTestDodel () {this.modelProperty = ko.observable (); This.myCompute = ko.computed (function () {return "test";}); } MyViewModel () {var} = this; Self.myTestModels = ko.observableArray (); } Var vm = new MyViewModel (); Ko.applyBindings (VM); $ (Document) .ready (function () {$ .getJSON ("http://MyUrl.com/api/MyController", function (data) {var viewable data = to.mapping.fr JS (data); Var array = observation data (); Vm.myTestModels (array);});}); & Lt; Tbody data-bind = "foreach: myTestModels" & gt; & Lt; TR & gt; & Lt; Td data-bind = "text: model property" & gt; & Lt; / Td> & Lt; Td data-bind = "text: myCompute" & gt; & Lt; / Td> & Lt; / TR & gt; & Lt; / Tbody & gt; [{"ModelProperty": "My Property 1"}, {"Model Property": "My Property 2"}]   
 What is the data for model property show, but chrome javascript The console says: Unacceptable error: Unable to parse binding message: ReferenceAir: My computer is not defined; Binding Value: Text: Microdoot  
 It appears to me.mapping.fromJS is not converting it into MyTestModel. I'm thinking because Knockout does not know about my test model, but I'm not sure How is that to tell about my model?  
 Still, thanks for everyone!   
 
 
 You did not specify that array items should be converted to MyTestModel.  
 It converts each array item into MyTestModel:  
  $ (document) .ready (function () {$ .getJSON ("http: // MyUrl. Com / api / MyController ", function (data) {var array = ko Utils.arrayMap (data, function (item) {new MyTestModel (item.modelProperty);}); vm.myTestModels (array);});   
  
 I hope this helps.   

 

mysql - GROUP BY DAY(FROM_UNIXTIME) unexpectedly changes count -

I am accumulating session IDs, IP addresses and timestamps of individual website visits, and all associated pageviews in the database. This includes more data, but related data has been removed from this query:

  SELECT page views .id, visitors.time, visitors, visitors. Pageviews on visitors coming from visitors. Session = Pageviews.session Order by visitors. Time ASC   
 There are some such results:  
  ID time session IP 1048 1371473496 nhie5sh2tiufs2ufupcremc6c2 x88.xxx. Kskskskksksks 1050 1371474103 8hfphqvq5ri6muc84oidp7q195 X6xkkskskskkskskskksksks 1062 1371474 9 56 hhgssr4v26pjbilkg8d81olqj7 Xxxkks3xkkskskskksksks 1066 137147633 9 ic8iqd0a4mpoelni15n4tq3404 Xlxkkskskskkskskskksksks 1067 137147662 9 ockivrm61upk7ss5ni4n8muv23 X2xkkskskskkskskskksksks 1070 +1371477856 5tdj9rrd1qsvafovufnkgh8r26 Xxxkksksks .

 The total number of visitors (different IPs), visits (different sessions) And the pageviews (separate pageview id), I ask the database like this:  
  select count (differentiate (visitors.IP)) as 'visitors', count (individually) (Visitorship)), 'Visits' joins visitors with 'Pageview' in the form of Count (PageviewId). = Pageviews Session   
 which gives something similar to the following:  
  Visitor Visit Pageviews 211 244 412   
 However, I Use archived timestamps for those years, months and days. To get that data, I wrote the following question:  
  SELECT DAY (FROM_UNIXTIME (Visitors.time)) as 'de', MONTH (FROM_UNIXTIME (visitors.time)) 'Month' Year ('FROM_UNIXTIME' (Visitors.time)) as 'Year', Count as 'Visitors' (separate (Visitor.IP)), Count as 'Visits' (Separate (Visitorship) )), Count (Visitors on Visitors from Visitors to Pageviews 'Pageviews') = Pageviews C By year, month, year order of year, month, day DESC   
 This works very well, at that date, pageviews and visits are correct:    Day Month Year Visitors Visits Page Views 20 6 2013 40 43 59 19 6 2013 80 90 112 18 6 2013 62 66 173 17 6 ​​2013 43 45 68   
 As you can see, here the pageview reaches up to 412 and up to 244. What has kept me at night, however, is that of visitors Is not increased Nkya 211, as it should be, but instead of 225. I do not know why this is happening only for visitors  
 Sorry for the long question Any ideas will be highly appreciated.   
 
 
 Since you are counting a different IP, when you group groupings per month (months) The number of different IPs, i.e., if they travel in months, people can be counted more than once. For example: 12.123.456.78 visits in March and April, this is a specific IP counted each month, but if there is only one separate IP if the group is not from month to month, then you do not want to aggregate total COUNT (DISTINCT) Can not add results of a grouped COUNT (DISTINCT) only.  
 This functionality can be helpful because it puts some light on repeat visitors.   

 

CodeIgniter redirect to another function when request is made by cURL -

I have a function, "Function A", a codeigner controller that contains a function redirect, "Function B "to send an email when this data is collected to collect my problem is that when I enter the function A URL in the browser, the function works as expected and the redirect to function B works. .. But curl scroll to function a Is called by IV, and is it possible to redirect function in this scenario is used to do the function belongs but redirect function B does not work (when the request is made by curl)?

Can you show your curl code? I think you use something like this:

  $ ch = curl_init (); Curl_setopt ($ ch, CURLOPT_URL, $ url); Curl_setopt ($ CH, CURLOPT_HEADER, true); Curl_setopt ($ CH, CURLOPT_FOLLOWLOCATION, true); Curl_setopt ($ CH, CURLOPT_RETURNTRANSFER, TRUE); $ Result = curl_xac ($ CH); Curl_close ($ ch);   
 Check this string (it must be set to true):  
  curl_setopt ($ ch, CURLOPT_FOLLOWLOCATION, true);   
 And you can use the next thing (in the example of topperren):  
  function first_function () {ob_start (); // do stuff $ this- & gt; Second_function (); Ob_end_flush (); } Function second_function () {// send email}    

 

python - Using Property to duck type two models -

I have a dynamic model that can have one of two objects through its related foreign key (call them Click on object1 and object2 ). Two other classes are functionally nearly identical, but this involves a little different information, on the suggestion of another Stack Overflow question, I am setting up Python method property () and which I am also receiving the object that exists. It looks like the following:

  class master (models.Model): object 1 = model. Exotic (Object 1, Blank = True) object2 = Model Forwardkey (object 2, empty = true) def get_object (self): if self.object2_id: return self.object2 else: return self.object1 def set_object (self, example): if isinstance (example, object 2): self.object2 = Example self.object1 = None else: self.object2 = None self.object1 = Example Object instance = Property (get_object, set_object)   
 This is a simplified version of the class. I thought everything was working properly. I was able to set, and was able to get the information, and could display data organized in  objectInstance  on many of my pages. I am using django-tables2 to display information in tables, and it Was also able to show all the information. However, when I try to solve the data (using the provided convenient arrows) I get the field error:  
  on field error / workflow / list / request / keyword u_objectInstance The farm can not be solved. The options are: Object 1, Object 2   
 What is happening with any idea? Or what is the code snippet for you to see what is the reason?  
 EDIT:  
 It seems that I am not the only one with this problem. This post seems to indicate that it is a problem with django-tables2  
 It seems that when the table can display information placed in a  property  It has trouble troubleshooting   
 
 
 If you want to use a decorator, see.  
 But the best way  
  Edit   
 It may be that:  
  class Master (models.Model): content_type = models.ForeignKey (ContentType) object_id = models.PositiveIntegerField () objectInstance = generic.GenericForeignKey ('content_type', 'object_id')   
 Therefore, you You can do this:  
  & gt; & Gt; & Gt; T = Master (object instance = object2 ()) & gt; & Gt; & Gt; T.save ()> gt; & Gt; & Gt; T.objectInstance & lt; Object2: a_description & gt; & Gt; & Gt; & Gt; T.objectInstance = Object1 ()> gt; & Gt; & Gt; T.save ()> gt; & Gt; & Gt; T.objectInstance & lt; Object1: a_description & gt;   
 Hope it helps!

c# - Getting a singleton instance using SimpleInjector for a class which implements a generic type, not actually returning a singleton -

I have to face some strange code-issues, and in the end it has seen that as a singleton It is considered to be working in the form, actually there is not a singleton, it is a cash-class, so I'm ending multiple versions of the same cash. I have written some test codes below, and this should work in my eyes. Am I doing something wrong, or have I stumbled into a bug?

  Public Class GenericClassesNotRegisteredAsSingletonTest {Public Interface ICacheManager & lt; T & gt; {} Public Square SettingsData {} Public Category Settings Cache: CacheManager & lt; SettingsData & gt; {} Public Class Cash Manager & lt; T & gt; : ICacheManager & lt; T & gt; {} [Test] Public Zero Test () {var Container = New Container (); Var registration = Lifestyle. Signalton .CreateRegistration (typefacetch), typef (settingscatch), container); Container.Update registration (typef (ICK manager, & lt; settings data & gt;), registration); Container.Verify (); Var cache1 = container.GetInstance & lt; SettingsCache & gt; (); Var cache2 = container.GetInstance & lt; SettingsCache & gt; (); Bool sameRef = cache1 == cache2; Notice. That (sameRef == true); }}    
 
 
 You made the following registration:  
  _container.AddRegistration (service type: type (ICacheManager , registration: registration);   
 And you are following the following solutions:  
  _container.getInstance & lt; Settings cache & gt; ();   
 You have not explicitly registered  SettingsCache , but only  ICacheManager & lt; SettingsData & gt; Since  SettingsCache  is a solid square, the simple injector will solve it for you as a transient example.  
 To resolve the solution either  SettingsCache  or  ICacheManager & lt; SettingsData & gt; Instead, you can register another one using the same  registration  example, for example:  
  _container.AddRegistration (service type: type (settingscatch), registration: registration);   
 will warn you about this.   

 

Eliminating part of arrays in matlab -

Assume that we have a 100 * 4 array.

We also have a 100 * 1 array, say 1 and 0, assuming that N1 is.

We want to create an array * 4 from the array 100 * 4, where we include only those columns for which the second array is 1.

One way to do this is through a double for the loop. Is there an easier way?

Then, we have

  A = [332 44 33 22 33 55 33 211 ..... [823 44 12 98 1] 23 32 9 11. ... .... .... ....   
 and  
  b = [0 0 0 0 0 0 ...]   
 and we want  
  c = [[332 22 ... [823 98 ... ... ... .]    
 
 
 You should use:  
  C = A (:, B == 1);    

 

how to add a dynamic date filter to Access report -

I am accessible and very new to VBA.

I have created an access database and report. One of the columns in the report is a date column and I want to create a dynamic user filter where the user can enter the date range and the query can accept that filter.

I am using Access 2013. On the property sheet I see a lookup section, where I can select a textbox, listbox or combo box. I also see a section 'input mask'. Do I need to use these, and if so, how? Do I need a VBA code anywhere?

I usually make that form in which the user can keep any dynamic information Can be added. Even if this is only one date field, then it's okay.

The query behind the report will be the date fields you use, and you can

  = [form] in the criteria! [MyFormName]! [MyTextBoxName]]   
 Where MyFormName is the name of the form mentioned above, and MyTextboxName is the name of the text box that the user adds the date.  
 Then press a button that opens the report on the form!   

 

r - Shiny Binary Check boxes -

I was thinking that for a glossy check box it is possible to inspect each other in the UI, if I One should be examined, the other should be unchecked, exactly the opposite.

I came to the Function Updates checkbox but the example shown is used for server side, is it possible to check the check box between each other on the UI side?

Thanks,

How is this commonly used for radio buttons Is ? Watch RadioButtons Is there any reason that will not work here?



standards - Does the top-level value in JSON have to be an array or object? -

यह वस्तु सचमुच मान्य JSON है:

  {"foo": "bar"}   
 और इसलिए यह सरणी शब्दशः है:  
  ["foo", "bar", 1, 2, 3, null]  < / Pre> 
 लेकिन स्वयं के द्वारा एक तार के बारे में क्या?  
  "foo"   
 या स्वयं के द्वारा कोई संख्या?  
  0    
 
 
 संक्षिप्त उत्तर  हाँ  है 
 JSON को वस्तु के रूप में स्ट्रिंग के रूप में प्रतिनिधित्व करने के लिए और स्ट्रिंग को ऑब्जेक्ट में कनवर्ट करने के लिए प्रयोग किया जाता है। 
 यदि आप स्ट्रिंग को ऑब्जेक्ट या एरे में बदलने की आवश्यकता नहीं है तो यह JSON से संबंधित नहीं है।   

 

asp.net - jQuery: adding a class to child elements x number of times -

I have a Dave star performs the racquet which displays 5 graded-out stars. I have been given a number and depending on the number, I need to add a CSS class which turns the grade-out star into a colorful color. Is there anything that I can complete for a loop or with it? what?

Here's HTML:

  & lt; Div id = "star rating" & gt; & Lt; Div class = "jquery-ratings-star" & gt; & Lt; / Div & gt; & Lt; Div class = "jquery-ratings-star" & gt; & Lt; / Div & gt; & Lt; Div class = "jquery-ratings-star" & gt; & Lt; / Div & gt; & Lt; Div class = "jquery-ratings-star" & gt; & Lt; / Div & gt; & Lt; Div class = "jquery-ratings-star" & gt; & Lt; / Div & gt; & Lt; / Div & gt;   
 And this is what I am trying to do. It seems that I am engaging it.  
  $ ('.jquery-ratings-star'). Each (function () {for (var i = 0; i & lt; nbrStarsVoted; I ++) {$ (this) .addClass ('.jquery-ratings-full');}});    
 
 
 Simple in this form,  
  $ ( '#RarRetting Div: LT (' + NBR StarWit + ')' ' Adquass ('jquery-ratings-full');   
   

 

php - Array_Push AutoComplete -

I have a form that receives the "from" field for the flight:

 < Code> & lt; P & gt; & Lt; Label & gt; & Lt; / Labels & gt; & Lt; Input type = 'text' name = 'nerene' value = '' class = 'auto' id = "1" & gt; & Lt; / P & gt;   
 And I have the autocomplete method:  
 $ return_arr = array ();  
  if ($ conn) {$ ac_term = "%" Get $ _ ['word'] "%"; $ Query = "SELECT table2.CityName, table2.CountryName, table2.AirportName from Table 2 where CityName: word"; $ Result = $ conn- & gt; Ready ($ query); $ Result-> BindValue (": word", $ ac_term); $ Result-> Executed (); / * Retrieve and store results in the query. For $ / ($ i = 0; $ i & lt; 3; $ i ++) {if (get $ line = $ result-> (PDO: FETCH_ASSOC)) {Array_push ($ return_arr, array ( 'Label' = & gt; $ line ['cityname'], 'value' = & gt; $ line ['citcode'])); Array_push ($ return_arr, array ('label' = & gt; $ row ['CityName'] + "" + $ row ['AirportName'], 'value' = & gt; $ line ['citcode'])); }}   
 This code works fine when I exclude the + $ line ['airportname'] but as a dummy example to auto-complete it Want to show: Athens, Athens Airport  
 Row names, connections are all right How can I do this?  
 Thanks   
 
 
 In PHP, this . , No  + . The line ['airportname'], 'line', 'array_push' ($ return_arr, array ('labels' = & gt; $ line ['cityname']]. "" $ Line ['airportname'], '' lang-php prettyprint-override " Value '= & gt; $ line [' citcode ']));    

 

Java: read bytes from a utf-8 file -

I have a file that contains UTF-8 data in this file for every Unicode word / line any BOM ( Byte order mark) and neither any length / size information.

I have to read the offsets offset (yes bytes!) Length. If the functions of the API work offset by reading the bytes, reading bytes or reading bytes, it will really be helpful.

Example Content - "100 degree information", the length of this material is 9, if I request to read 9 bytes, then he should read everything. Currently it is only reading 8. It seems that the API is treating the Unicode character as 2 characters.

How to read the content correctly? Which API is used for the same API?

But Unicode characters for the degree are actually two bytes when encoded UTF-8. A degree symbol is represented by bytes c2 b0 . If you really want to read bytes on a specific offset in a file, then you can use RandomAccessFile in Java, but I doubt what you really want. Perhaps the easiest way to do it seems that you want to use FileReader and either read an array of 9-letter characters, or a large Read only 9 characters in the character array. For example: Try

  (Reader Reader = New Input Strieder Reader (New File Inputstream (File Name), "UTF-8")) {char [] buffer = new Charge [1024 ]; Reader Read (buffer, 0, 9); }    

 

jquery - Placing image in front of background -

I have a section that slides with a blue background, I try to put a picture in the upper left corner I am doing it but it is hard to see and the blue background disappears.

HTML part:

  & lt; Header ID = "Main" & gt; & Lt; A href = "#" id = "stackoverflow" class = "symbol" & gt; & Lt; / A & gt; & Lt; / Header & gt; & Lt; Section id = "stack" category = "news" & gt; & Lt; / Section & gt; Click (function () {$ ('# stack'). Toggle ('Slow')   
, $ St); $ ('# Stack') CSS ({'background': 'url (stack.jpeg) no-repeat', 'position': 'absolute', 'z-index': '1'});});   
 CSS:  
  #stack {float: left; } .news {status: Completed; Z-index: -1; Width: 600px; Background color: # 0000FF; Padding: 10px; Range radius: 10px; Box-shadow: 3px 2px 3px # 000; }. A {status: absolute; Text-decoration: None; Color: #fff; }. News: Hover {Color: # DC-692e; } .news td {padding: 5px 10px; Border bottom: 2px #fff solid; }   
 By putting an image in the corner I do not try to:   
 When I try to add an image to the corner, here's a picture:   
 Thanks!   
 
 
 Due to the blue back ground is disappearing, due to overwriting your background. What you can get after:  
  $ ('# stackoverflow'). Click (function () {$ ('# stack') toggle ('slow' $ st); $ ('# stack'). CSS ({'background': 'url (stack.jpeg) No-racquet blue ',' Position ':' complete ',' z-index ':' 1 '});}); Apart from this, after placing the image in the background, I say that adding some padding at the top of the element means that the text does not eliminate your image. .  
 A better solution is to actually inject that image into a particular element. IE:  
  $ ('# stack'). Prepaid ('& lt; img id = "theImg" src = "theImg.jpg" / & gt;')    

 

linux - Fastest way to create animated gifs from mp4 -

I get the batch process in animated GIFs in a very high number (200,000 +) small MP4 (less then 10s) have to keep. I think I have tried every possible command line to do this, but it still takes a lot of time to produce quality gifs. Currently I use FFPAP to open the image (JPG), and the image magikk converts them to collect. It creates a high-quality GIF, but takes a lot of time and uses a lot of memory and CPU, even with tile-to-memory storage and map boundaries.

I have also tried to create animated GIF using FFPAG, but the quality is awesome in the best. Besides, I tried to use gifsicle, which appears to be fast, but It only takes gifs as input, and uses ffmpeg to produce poor quality gifs.

Does anyone have some high quality command line dishes, GIF creation?

For the first time you should create a maximum quality JPG image using the mplayer And jpeg option set 100 (jpeg: quality = 100).

  mplayer -ao null -ss 0:00:00 -endpos 10 mts .flv -vo jpeg: outdir = jpeg_dir: quality = 100   
 next , You need to convert by using  convert  to generate from JPG, just type:  
  for i /Jpeg_dir/ * .jpg; Change "$ I" "$ {i% .jpg} .gif";   
 and finally use  gifsicle  Animated GIF:  
  gifsicle --delay = 10 --loop ./jpeg_dir / * .gif & gt; Anim.gif   
 In addition, you can use the customizable level flag  - customizable = 03 . File size may be helpful in reducing:  
  gifsicle --delay = 10 --optimize = 03 --loop * .gif> In addition, Anim.gif   
 In addition, you can manipulate with the number of colors  - color of the current color num  and  - color scheme < / Code> to determine the most suitable palette.   
 
    
 
 
 < P> Apart from this, I try to manipulate with the described flag and found the most useful option to get better quality of GIF-image generated:  
  gifsicle - delay = 3 - optimize Do = 03 - Color-mode mid-cut --loop * .gif & gt; Anim.gif   
 To be consistent with the animation speed, be accurate with  - delay = NUM ​​, depending on the FPS of the original video.   

 

asp.net mvc - RESTful application -

Roy fielding came with this idea and many applications have been made around this, but I am really confused Where is it called Representative State Transfer? In almost every application, we do not go from one page to another and when we go from one page to another, the application changes.

After reading some articles, I know 1. The build is on HTTP, 2. Allows caching. 3. Resources can be accessed using URI.

What are the other benefits of regular ASP.NET web form application? Please help why and where will i need cool application.

BTW I have been programming ASP.NET web forming for a long time and in fact I do not know about new technologies.

Thanks in advance.

I see that this trend is:

1996 - Classic ASP

2002 - ASP.NET

2009 - ASP.Net MVC

2012 - ASP.Net Web API and Single Page App < Maybe you mean a single-page application through "restful application":

This is where the trend is going, I believe - Instead of creating a UI and business logic on the server side, you can use the Rich Protocol Types can only create rich client side UI communicating with the server, through business logic and tragic closure on the server side), so that you can provide a better experience to your users. In addition, you can create multiple UIs for various platforms (web UI, iOS, Android, Windows Phone, Windows 8 app, etc.), all of which are consuming the same API service.
