Hosting powershell import-module failure -
I'm trying to host PowerShell and the "ServerAdmin" module is required to run the Get-Windowsfeature OS server 2008 R2 is I can successfully run "import-module serverAdmin" on PS comamnd signal, so I know the machine config is good. However, I can not get it to work in my custom C # host. I've tried two approaches, first shown below, using the import-module command, the error says "specified module 'server admin 'Was not loaded because any module file was not found in any module directory. " The second approach, using InitialSessionState.ImportModule (), also fails. No error has been reported from that method, but the get-windowsfeature command is ignorant.
The first method:
var ps = PowerShell.Create (); Var cmd = ps.AddCommand ("import-module"); Cmd.AddArgument ("ServerManager"); Ps.Invoke (); Console.WriteLine ("Errors"); // produces "the specified module 'ServerAdmin' was not loaded because no valid module file was found in any module directory" foreach (var error in ps.streams.Error) {Console.WriteLine (error.ToString ( )); } The second approach:
var ps = PowerShell.Create (); Var initial = InitialSessionState.CreateDefault (); Initial.ImportPSModule (new [] {"ServerManager"}); Var Ranspace = Ranspace Factor. Criterion (initial); Runspace.Open (); Ps.Runspace = Ranspace; Ps.AddCommand ("Nights - WindowsFeature"); Var result = ps.Invoke (); // throws an exception because Get-WindowsFeature is not a foreach (result as a result of result) {Console.WriteLine (results); }
found the problem I was creating x86 or x64 or any Was obviously x86 default and of course server-2008 was happy to run it in wow, but the server admin module is not available in that context.
android - How can I test timed Notification? Or is my code somehow wrong? -
I want to distribute timed notifications (everyday, 5:00 AM), and this is the alarm code Tries to use:
Intent to appIntent = new intent (this, NotificationService.class); AlarmManager AlarmManager = (AlarmManager) getSystemService (ALARM_SERVICE); Pending Internet Penientent = Pending.text (this, 0, appointe, 0); AlarmManager.cancel (penIntent); Calendar cal = calendar.justinstance (); Cal.set (calendar.HOUR_OF_DAY, 5); Cal.set (calendar.min, 00); Cal.set (calendar. SECOND, 00); AlarmManager.Settering (alarmman.rtc, cal.getTimeInMillis (), alarmManager.INVAL_DAY, Penentent); NotificationService.class looks like this (least important part):
int id = 001; Information Manager mNotifyMng = (Notification Manager) getSystemService (NOTIFICATION_SERVICE); NotificationCompat.Builder mBuilder = New Notification Builder (main activity.) .setSmallIcon (R.drawable.icon) .setContentTitle ("Test") .setContentText ("Test!"); MNotifyMng.notify (id, mbuilder.build ()); StopSelf (); I can not seem to do this work. When I set the emulator clock to 4:59 or something else and wait to change at 5:00, no information is seen and I have no other way to test it. I hope you know a way to check it or find a bug in my code.
I believe the problem is that you cancel pending , But then you have to recreate it before setting it to alarmManager . // Pending pending AlarmManager AlarmManager = (AlarmManager) getSystemService (ALARM_SERVICE); Pending Internet Penientent = Pending.text (this, 0, appointe, 0); AlarmManager.cancel (penIntent); // Repeated pending attendant app entity = new intent (this, NotificationService.class); AlarmManager AlarmManager = (AlarmManager) getSystemService (ALARM_SERVICE); Pending Internet Penientent = Pending.text (this, 0, appointe, 0); Calendar cal = calendar.justinstance (); Cal.set (calendar.HOUR_OF_DAY, 5); Cal.set (calendar.min, 00); Cal.set (calendar. SECOND, 00); AlarmManager.Settering (alarmman.rtc, cal.getTimeInMillis (), alarmManager.INVAL_DAY, Penentent); To cancel pending you need to create it exactly as you do for the first time, then AlarmManager s Cancel () as you like but then you need to make it again to set an alarm to pending ** I hope you know some ways to test ...
may be a better way, but for testing purposes For, I will occasionally set up a global debug flag is changed between the testing and production. Then say it can be 4 hours and 2 minutes, it can be a bit more difficult during the day, but you can change the time, time, hours, minutes or whatever. Once you know that this is triggering at the right time, you can change it back and still test it when the time comes for that day but now you know that it should be done.
In C#, how do I initialize an Object with key/value from an Collection -
I am very lazy to type all the properties of my object, so instead:
myObj.property1 = value1; MyObj.property2 = Value2; MyObj.property3 = Value3; MyObj.property4 = value4; MyObj.property5 = value5; ... Is there any way to do this?
object myObj = new object (); Foreign currency (string quaprint in myCollection.AllKeys) {var curValue = collection [curProperty]; MyObj [curProperty] = ON; // ???????????? }
Yes, you will need to use the system. Reflection to work: For (int i = 1; i & lt; 6; i ++) {PropertyInfo prop = myObj.GetType (). GetProperty (string.Format ("property {0}", i); if (prop == null) {continue;} prop.SetValue (myObj, collection [prop.Name], null);} In this example, I'm assuming that there is a string indexer on the name of the property in the store (you may need to recover it in a different way). I also agree I have only 5 attributes ( i <6>), you have to set accordingly. But you get this idea.
Commented by Gimshikhel In spirit The ordering is also an option. 'I'm not working here as an example because I'm not 100% on code, but consider web services. Web Services (D) do their work with serialization.
So, you technically distribute an XML file to the object and you get all the benefits of Deserialization - and there are quite a few which I can think from the top of my head that the values of propertiesA new example of the object did not > - I do not believe how it outlines - but I know that this is because I have once Followed the bug !
ios - iPad app not laying out properly -
I have an iPad app for which I received the code.
I am relatively new for the development of the iPad, please bear with me ...
The app was compiled by the contractor in off-site in 2010. Since then, my company has been acquired and we are in the process of re-branding. I seem to have a simple task in this app to replace our logo with a new logo. It should take a few minutes - just drop a new logo into code, compile it, and bam! was done.
There is a problem compiling the code ... The working app launches in landscape mode and fills the entire screen with its interface when I compile the app in the simulator or use my iPad Run on USB cable via my Mac), the screen launches in landscape mode, but the view is in the picture mode, in intermittent locations during the app, from the scene landscape to the por Visit trait layout.
This is driving me crazy because I do not even know what to see. I need some references to AutoRotateToInterfaceOrientation - I think it has been deprecated. Can this cause problems?
I know that a lot has changed since 2010. I am currently running the latest version of XCode on a new Mac. (Which I think, my predecessor had never compiled the app here, but fully trusted the contractor ... what I can see, this can be a problem that is with everyone, but No one knew)
UPDATE I have to test with an old Mac (with an earlier version of XCode). I moved the app code to the old Mac, changed some settings, and it works correctly. I have also found that the layout is not perfect on any app on my new Mac. For example, leaving a button near the top of the form can be scrolled from above, so it is not visible either. Is there a setting in XCode that defines this behavior? The view controller turns into an iOS 6.0 probe for orientation position. // Override to allow Orientation other than the default portrait orientation.

Thanks in advance Yes, amber is a page app, because you only go to a page, this Loading the app, you no longer need to get more pages from the server that the amber app handles everything. Large apps such as you are suggesting, you put each object type (model, controller, route, template, scene, etc ...) in the own directory for the organization. emberjs for almost a week and I have studied the examples That was a single page app. I have been asked to work on a project which extends more than 30 pages and I do not know what the directory structure will be and if Amber is the best tool, as I have never seen an application which is the other Links to pages?

git - How do I overwrite my local repo with the one on github? -
I got an out-of-date repo with nothing to add on my machine. I got the latest stable branch from Gitub I want to draw
Should I Clone It? I'm not sure.
I think you should be able to fetch all the files, then reset them to the original :
git fetch --all git reset - hard root / master You can probably do it in any order, too.
If you added any files that have not been tracked, clear:
git clean -f The advantage of this approach when cloning a new directory is that you still have some history / if you do not care about that data exactly, then the approach is okay.
codea - How can I build an IOS app on IOS? -
I have created an app with Coda and exported the encoded project. Is there a way to create it on iOS (or Windows)?
Definitely.
Some people on Ininjas have successfully ported the CLAG-LLV Toolchain to run on iOS - Install DEB on your iOS device. You can access your desktop from your computer on the development surrogate ( (I do not remember there is any other package to install, but perhaps from Audiq. To Sidia, etc., just google it) After this, you Compile and link all files Of course, Xcode uses a proprietary format for project files, so you can not go ahead and expect to build compiler from Xcode project, but for example, all < Code> to specify Write a Mekfail. M files to be compiled. After this you will have an executable file, which you may or may not need to coding. iPhoneOSX. Y.sdk folder). The device also has to jailbrack.
javascript - Why use === instead of == when comparing a String -

एक स्ट्रिंग मान की जांच करते समय मैं '==' का उपयोग करता हूँ लेकिन मैंने ऐसे उदाहरणों को देखा है जहां '===' उपयोग किया जाता है उदाहरण के लिए,
के बजाय यदि ("true" == "true") {चेतावनी ('सच'); }इसका प्रयोग किया जाता है:
यदि ("true" === "true") {चेतावनी ('सच'); }इस के पीछे तर्क क्या है? दोनों का उपयोग मामलों की अपेक्षा के अनुरूप काम करने लगते हैं।

reporting services - Editing RDL Reports with SSDT (SQL Server Data Tools) -
I have some RDL reports that are hosted on my SharePoint 2010 website. I recently installed SSDT device for VS 2012, and I can create a new reporting project to revolve some reports with data sources, but what I really want to do is edit my existing reports on SharePoint Are hosted if I try to "open" the RDL file, then only I get the schema information of the "behind the scenes" report, Ain does not currently support.
I am running SharePoint 2010, with SQL Server Reporting Services 2012, SQL Server 2012 works best with SSRs 'Business Intelligence Development Studio', any assistance that is appreciated.
When you have bids, you can only keep your 'RDL' files in the place you save. Then say: "Add existing" and point to the location and get all the data from the code if you are familiar with the Report Builder, which is basically a water-down version of the bid BIDS, however, make the memory better Because it is an IDE created specifically to design SSIS, SSRS or SSAS applications.
So if you do not have any solutions, then create a 'Report Project', make a datasource (you need to know the database and how to connect it or other datasource) then go to the report folder and Select 'Add existing' and I mentioned above. You can only find your RDL files and they will be visible there.

Neo4j linked list - multiple nodes -
I am working on understanding how to improve performance and use linked lists to create activity feeds on Neo4j I'm still working on learning cipher, so I have a question. I have found an example of some linked lists, but I need a large number of lists so that in the end all the pieces together in my head
I used it The code is found to be more useful than the example of Neo 4G manual. Still I'm a bit confused ... Does anyone modify it so that seven nodes can speak seven items in the link list, and then insert a node in front of it?
Yes, I am trying to add the latest status update at the top of the linked list. This example does not really do this, but it is closed .. Then looking for some models .. No, I'm not really coding yet, Still trying to master Cypher for the first time - For the next two weeks, it will continue to study. There is Ruby on the Railways side work. Just need to understand the linked lists used with the SIEF / Neo.
create zero = {name: 0, value: 0}, two = {value: 2, name: 2}, zero - [: LINK] -> Two - [: LINK] - & gt; Zero ==== Zero ==== MATCH Zero - [: LINK * 0] - & gt; Before, after - [: LINK * 0 ..] - & gt; Zero, first- [old: LINK] - & gt; Before that WHERE.value? & Lt; = 1 and 1 & lt; = After.value? Dellie Old ==== Zero ==== MATCH P = Zero-New = Create = {Name: 1, Value: 1}, First - [: LINK] - & gt; New Value, New Valley - [: LINK] - & gt; [: Link * 1 ..] - & gt; List_length as zero return length (P)
Whatever I'm trying to do in my mind, it understands first and zero data sets - I approx. is it, but to see that it has been done with more than two early nodes on one set so that to clear any confusion, thanks!
The front node is special because there are no link links in it, usually you are concerned with the head node , So it's about taking this node on the head node and removing the head node one step further. Something like this:
user = node: connect to node_auto_index (user = "me") user [old: MESSAGES] - & gt; Make head old - new_heads = {title: "title", date: 2348972389, text: "text"}, user - [: MESSAGES] - & gt; New_head - [: LINK] - & gt; Head

llply (l.temp, function (l) {if ((unlist (strsplit (names (l), "_")) [3]) == " A (error) (List (L (L), A () (return (L)}}) This error I am receiving:
"_") In error (Stripspit (name (LLS), "_"): Error in evaluating argument 'x' in choosing a method for function 'unlist': character logic Help is appreciated on what I am doing wrong.
You list You can find patterns in names that give you an index:
grep ("_ A $", name (l.temp)) And then use it in the subset:

php - How to use multiple languages in one view in CodeIgniter? -
For example, I would load it as language (BTW. I think only the first of these two, the other in English Will be ignored):
$ this-> lang- & gt; Load ('module_messages', 'english'); $ This- & gt; Lungs-> Load ('module_message', 'check'); But I can only use something like this:
this $ $ echo-> lang- & gt; Line ('language_key'); This does not work:
$ echo-> lang-> line ('language_key', 'english'); Any ideas how to resonate both of the language translations in one view at the same time:
this $ echo-> lang- & gt; ; Line ('language_key', 'english'); Copy $ this- & gt; Lang- & gt; Line ('language_key', 'check'); How to get such a thing? Unfortunately there is no way to do this because the key is loaded for a language file.
is. This is not specific to loading multiple files.
However, there is a way around it and it is to use a prefix like this:
$ this-> lang - & gt; Load ('en_module_messages', 'english'); $ This- & gt; Lang- & gt; Load ('cs_module_messages', 'check'); Transcript $ this- & gt; Lang- & gt; Line ('en_language_key'); Transcript $ this- & gt; Lang- & gt; Line ('cs_language_key'); If you name the language files and keys, then they will definitely fight. Therefore, we add the ISO language prefix for language files and line keys. So that both languages should be allowed to use them both at the same time.
show new info on list click PHP -
I have a PHP page, which creates list-items when a form is submitted, form 5 in the form text If the value sends, two first values of the form are sent back and are displayed in the list element, it looks like:

For php ($ i = 0; $ i & lt; count ($ content_array); $ i ++) {$ value = explosion (';', $ content_array [$ i]); $ Heading = $ value [0]; $ Grade = $ value [1]; $ Link = $ value [2]; $ Pic = $ value [3]; $ Desc = $ value [4]; & Lt; Li '& gt;' $ Titel '& Lt; Span & gt; ' $ Grade '& Lt; / Span & gt; & Lt; / Li & gt; ';}? & Gt; & Lt; / Ul & gt; I do not know that to make the list element clickable and when you click all the values in the content_ar, it should be displayed and the list should be missing, Still the same page (index.php) but if you click on the first list-element then it is index.php? Page = First and second list-element index.php? Page = second and should be the same .. I think I should use the $ _ GET ['page'] in any way but I do not know much PHP, if If someone knows me in the right direction or knows any online manual for this then I will be happy! <
$ I & lt; Count ($ content_array); $ I ++) {$ value = explosion (';', $ content_array [$ i]); $ Heading = $ value [0]; $ Grade = $ value [1]; $ Link = $ value [2]; $ Pic = $ value [3]; $ Desc = $ value [4]; Echo '& lt; Li & gt; Echo '& lt; A href = "index.ph p?

android - How can I auto-pause the audio player in my app when another app starts to play audio? -
My app runs audio file I want my app to stop audio playback if another app audio starts playing I do not want two audio to interrupt each other. After the second app is playing audio, my app will start playing the audio again. How can I create it? Thank you.
Depending on how your app is running. While the application is running in the foreground (users are considering your screen) or if you have a "service" that is currently in the background and you want to continue the music (Ganga, Lazy Radio etc.) How are you going to handle these things different? Android uses internal system states, to determine which apps should put audio on the speaker. All these audio-manager requests are handled by Audio Focus () Release Audio Focus (), System Call would like to see you the most. For more detailed explanation see the Android Developer API, where you can explain it and document it quite well

Java: Recursively Finding the minimum element in a list -
I'll call it homework. I'm just looking for some points I'm ejecting my brain with this one, and I'm not getting it for my life. We are asked to find the minimum element in a list. I know that I need a novel here, but after that I'm not sure. Any hints would be great thanks.
/ ** Find the minimum element in the list. * * @ Ultimate * integer list * * * return the minimum element in the list / public static end minute (list & lt; integer & gt; t) {if (t.size () == 1) {return t.get ( 0); } And {list & lt; Integer & gt; U = T. SULIST (1, TCISE); In the most common sense, recursion is a concept based on breaking a job, and
- Breakdown of work How are you making each step "simple" ?
- Recursive call. At some point your function should call itself, but with less "work".
- What is the case of the base case one (usually trivial) that will stop the recursive process?
In your case, you are trying to create a function min which is a list. You are right in thinking that you can reduce your work by making a list short by one time (first thing can be taken out of the element). As others have mentioned, this idea is to check the first element (which you have just drawn) against the "rest of the list". Anyway, where the leap of faith comes. At this point, you can assume that your minute function will work on the novel, and just call a function on the novel (recursive call). Now you have to make sure all your calls will be back (i.e., make sure that it will not always buy again). This is where your base case comes. If your list size is 1, then only one element is the smallest in the list. There is no need to call again minutes , just return it (the part you already did in your original post).
jquery - AJAX and 200 OK messages: Are they required to complete a server side call? -
We are developing tracking systems that use the WordPress AJAX API, 3G calls on 3G AGX contracts and WordPress AJAX APIs This refreshes the page.
I see that sometimes my data entry efforts are failing at the back end and I agree (this is probably wrong) that this is happening because in our last AAGX call 200 is already clear, and breaks the connection, which means that the data is never stored.
Now I am under the assumption that as soon as a jQuery.ajax ({type: ' POST 'call has been issued, I can immediately close the page Even then my server side which I posted to receive, and
but my data test is showing that some data is not constantly being recorded. Do I have the right to think that this My last AJAX call should not be related to finishing (and before reloading the page) a pre-ajax call is cleared with 200 OK?
Thanks for any help!
Yes, yes If you send an AJAX request to the server, you can close the page, complete the server request (code execution).
But there is a point address, you do not know that your request has arrived at the server or not.
jQuery.ajax ("htpp: //", {type: 'POST'}); This is an asynchronous request, so it will execute the code in the background. Execution of this line of code does not mean that you have sent a request, after some time it works in the background.
- jQuery will parse your code, see what you want,
- This will create a xmlhttprequest object with the set option.
- And finally it will send the request to the server.
So if you close the page immediately, before the third step, the request will not be sent.
I recommend that you send a synchronize to the AJAX request and wait for any feedback on the fresh / closed page. Because Synchronous AJAX can temporarily lock the browser request, because the request is active.
JQuery.ajax ({url: url, success: function (r) {}, async, In this case, you must set an async fake to make it synchronous, : wrong});

The problem when I try to add a third series to illustrate a single vertical line (used as a "cursor", with a It does not display anything. I also tried to use two very close X values suggested by ACE donation: I also add Attempted 24 data points, 23 of which have a Y value of 0 and only one (on x position 5) is the Y value of 100. Since it is a cubic line chart, so my cursor appears with the "heel" below; On the lower part of the chart, other 23-digit cursors are also visible. Example: I have settings The nearest data indicates the x value of +/- 0.00001, but does not remove the high heel - which is as small as the smallest until I set it horizontally to the cursor position. . I am playing with this for the last hour or so, but I can not find a simple vertical line shown. any idea? The problem is that you are using scale = 2 for the vertical line series. Each scale calculates the visible data range and attempts to fit the data as it appears completely, I suggest that you add your vertical line data to a scale already present. OnTouchListener ) . This idea is to attract a 2-Datapoint series which will be presented as a single vertical line that I can use for my cursor. XYSeries cursorLine = new XYSeries ("", 2); Cursor Lean.ad (5, 0); CursorLine.add (5, 100); Dataset.addSeries (cursorLine);
XYSeries cursor lines = new XYSeries ("", 2); CursorLine.add (5.00000, 0); CursorLine.add (5.00001, 100); Dataset.addSeries (cursorLine); Unfortunately, it spreads the "cursor" line across the entire width of the chart, as if it assumes that it is made up of 24 data points instead of the specified 24 digits.

URL Schemes on iOS -
I try to launch an application (App1) from another application (App 2) using URL schemes I am here. Is there a way I can check the application name which is launching my app? Example App2 has launched App 1 (so can I check the name of app 2 1 app 1) Or can we get information on the source starting at App 1?
Thank you in advance
To apply to launch from any other application For, you need to configure "Supported URL Schemes" in your information plist file. You will be able to know the reasons for the following method in your app delegate along with your application launch.
- (BOOL) Application: (UIApplication *) Application FinishLaunchingWithOptions: (NSDictionary *) launchOptions
Here are the launch options
A dictionary indicating the application that was launched (if any). In this situation, the contents of this dictionary can be empty where the user started the application directly
are the possible keys
NSString * const UIApplicationLaunchOptionsURLKey; NSString * const UIApplicationLaunchOptionsSourceApplicationKey ; NSString * const UIApplicationLaunchOptionsRemoteNotificationKey; NSString * const UIApplicationLaunchOptionsAnnotationKey; NSString * const UIApplicationLaunchOptionsLocalNotificationKey; NSString * const UIApplicationLaunchOptionsLocationKey; NSString * const UIApplicationLaunchOptionsNewsstandDownloadsKey;
objective c - Game Center login -
My game players need to log in with the apple game center. If they are a new player for the game, then they must first sign in to the game center because I use the player ID as part of the data used to set up a new user account.
I have a game center class that I use to sign in to the player, or signs them to sign if they are not already, then here is the main code .
- (zero) setup {gameCenterAuthenticationComplete = NO; If (! IsGameCenterAPIAvailable ()) // // Game Center is not available NSLog (@ "Game Center is not available."); } And {nslog (@ "game center is available."); __Week type (self) weak Self = self; // Maintaining cycle error GKLocalPlayer * localPlayer = [GKLocalPlayer localPlayer]; // localPlayer public GKLocalPlayer __weak GKLocalPlayer * Vulnerable Player = Local Player; / Maintaining cycle error deletes weak player AuthenthenticateHandler = ^ (UIViewController * viewController, NSError * error) {if (viewController! = Null) {[weakSelf showAuthenticationDialogWhenReasonable: viewController]; } And if (weak player. Authentic) {[weak self certified player: weak player]; } And {{Weak gameman disabled]; }}; }} - (void) showAuthenticationDialogWhen appropriate: (UIViewController *) controller {[[UIApplication shared application] delegate] window] root view controller] PresentViewController: controller animated: Yes Full minus]; } - (void) certified player (Jikelokelpleyr *) Player {Anselog (@ "% @% @% @" player. Pleyraidi player. DisplayName, Kiladhiklias); LocalPlayer = player; GameCenterAuthenticationComplete = Yes; } - (zero) disableGameCenter {} And it works fine. But I have 2 problems
1) As I said that the player is new, they have to sign in to the Game Center before proceeding with the new user registration. This new registration is in the second category. So how do I hear GameCenter's variables gameCenterAuthenticationComplete = YES to other games? I read somewhere else that I can use a representative, but does he work in things? Will a notification be better in one object?
2) And more importantly, what if the player closes the modal to sign into the game center, where the call back / block where the modal is closed? So can I prompt them to sign in again or at least I can put a msg on the screen?
1) You gameCenterAuthenticationComplete by way of example that in your class header AppDelegate.m import and representatives of the interface can use your gameCenterAuthenticationComplete in (Appdelegate.h) in declaring an instance of that class came representative or you can reach sharedinstance class are the following measures adopted in your classroom Yourclass.h file

Any idea
If you have IP and traffic bytes in the file, So use the following to complete the work.

Javascript to enable, disable drop down menu in JSP file having Java code only, no HTML directly -
Let me introduce the design.
Each field in a JSP is created by a After writing the map, Now, the requirement: I have noticed that the JS function is called on Is there any way to get a job? Enabling and disabling should depend on the user how to select from one of the drop-downs. Sample code: Need immediate help, thanks. See the JSP page, it is clear that some areas of Change and On-HouseOut Event etc. , And in the So, instead of using the existing code I added my own method and introduced an on-change event. The type of " Now I added the following to JSP Where are the names of the criteria drop down menu, and Thus, the map . The name of the label, input type (drop down or other), input value, default value, etc. is added to map , say Map nameAttributes . Another class is general authors , which I do not have access to, which takes the value from map , parses them and writes the appropriate HTML code. writer.writeSelectBox (nameAttributes); It is called .
is a drop-down menu, depending on its chosen value, some other drop-down menus are disabled (shown in the UI but not modified) Or enable it. Since, I am not writing HTML code for additional fields, I can not write the function call event to do my work. onMouseOut event from the field, as shown in "View Source" . So I thought I could write my code to see the field value and affect other drop-down menu. But if I type warning in the JS function (check only), this will not warn me, this means that the function is not called and I can not write the enabled / debable code.
& lt;% map name = newHashmop (); NameAttr.put (GeneralConst.INPUT_MESSAGE, Const.MSG_FIELD_NAME); // ..... Author. All selected box (named etter); & Gt%; GeneralWriter class, those things are being written as outside stream like
out.println ("& lt; td Abrap> Selection Name = "+ strName"); Out.println ("style = \" width: "+ strWidth +" px \ ""); Out.println ("On Change =" + On Change); On Change " which you are looking for (right one) is java.lang.String and it was to be passed by JSP, as the behavior I wanted I want to do special work to call or call for a particular JSP.
& lt; Body & gt; & Lt; Script & gt; Window.onload = setModeForPara2 ('MemberTip','EmberState ',' Ceccestatus'); Function reset (event) {setModeForPara2 ('MEMBERTYPE', 'EMBARTSTATE', 'Ceccestatus'); } & Lt; / Script & gt; & Lt; / Body & gt; setModeForPara2 () is an incompetence / js function to enable because my requirement is in the original post I went . It checks whether the merchandise is 0, then the incompetent state and gray color to be presented in the Amberstate and Cequestats drop-down menu, otherwise enable them and remove the gray color.
resetevent (uri) There is also a JS function called when the reset button is clicked to present the state to the disabled state and the status field. setModeForPara2 () function is called whenever: 1 page has been loaded,
2. Change the value of the first drop-down (MMEBARTEEE) Is, and 3 The reset button is clicked. Solution of
cocoa - Running .app by double click on it and linking dylibs -
Will someone tell me how to run (run) .app (mac executable) xcode. And i try cocoa usage How, how Link or Load Designated Deals to AP.
and information using the DLDDLIRIBRRIAPP environment variable. How to give the relative path to the dial in the list.
Thank you in advance
It seems that you can store it directly You can run it by double-clicking "Explorer appel" in the organizer, and finally, you can copy it anywhere to run it.
By the way, when you first click on the Mac to launch this app for the first time, then only you will not run when you use "open" in the right-key menu to open it. So, it will work for you.
Line Detection openCV -
I'm running a code to find lines in OpenCV 2.1 in Visual Studio 2008, here's a part of the code :
IplImage * src = cvLoadImage ("parrot Pollock"); IplImage * dst = cvCreateImage (cvGetSize (source), 8, 1); IplImage * color_dst = cvCreateImage (cvGetSize (source), 8, 3); CvMemStorage * storage = cvCreateMemStorage (0); CVSeq * line = 0; Int i; Int choice = 0; CvCanny (source, DST, 10, 100, 3); Code compile the code correctly, but when run returns the following error: OpenCV error: the combination of formats (), file ........ \ Ocv in the unsupported format or unknown function \ Opencv \ src \ cv \ cvcanny.cpp, line 66
Any indication on how to fix it ...
By default when you load an image it loads as a color image. Kenny needs the image input and output of a channel. Therefore, I think that if you load your image as a gray scale or later change it into a gray scale, then it should work.
Either:
IplImage * src = cvLoadImage ("parr. .png", CV_LOAD_IMAGE_GRAYSCALE); or:
cvtColor (src, src, CV_RGB2GRAY);
jqGrid change formatter of cell when cell has no value -
I have a jqGrid that has one of the columns set formatter as hyperlink
{name: 'IDNumber', index: 'IDNumber', classes: 'hyperlink', search: correct, stype: 'text', formater: 'sholin', format options : {BaseLinkUrl: '#'}}, When a cell is not in the IDNumber value, then I want to change the format to string. The reason why I want to do this is when the cell has no value and does not display this gridline when it is linked as a formatter
Formatter showlink output and lt; for each input data containing strings (empty string) or number A & gt; element I'm not perfect, make sure I understand exactly what you want.
If I understand you correctly, then you need to make the link "clickable" even if the cell contains the empty string to do this so that you have all the columns in it Empty strings can replace some things like "& amp; nbsp; & amp; nbsp;" . Another option I can suggest is that you want to use my dynamic link format which I have described. It is very easy, but the predefined format is more powerful in the form of sholink . It shows how you can use it. Column {name: "mylink", width: 60, sortable: false, formatter: "dynamiclink", formatoptions: {cellValue: function cell valley , Line ID, row data, options) {return cell value! == ""? Cell Value: "& lt; span style = 'color: red' & gt; blank link & lt; / span & gt;"; }, URL: function (cell value, line ID, row data) {return / store / adapter? Id = '+ rowId +'? ' + $ .perm ({name: rowData.name}); }}} Allows to define the custom cell value and the URL used in the link. The source code of the formator that you can find displays the demo grid
Where I put some custom text (red text" blank link ") instead of empty string.

I created some Hello world basic app with phonegap, then in the terminal (Mac OS Sher) I run the following command:

What could be the problem with the connection?
And what are some other tools I can send on the Android device only through the device like USB?
Thank you: -)
I've got a solution if someone wants to know :
You have to use the device IP address and the developer is not found in the IP which is found in the developer settings on the device (where you see your developer token).
And then it will work (Don 'developer IP, annoying to lead the developers in the wrong direction, ask me.)
Some settings on device IP device were found in the entry (I do not remember which unfortunately, but it's there). Do not use the IP from the Developer menu that does not work: -)
android - How to specify HTTP headers for async imageloading in AQuery (AndroidQuery)? -
I have to specify a specific referrer to successfully load certain images on the remote host. (For example, the referrer should be "", otherwise the webserver will return HTTP 403)
The agency has a section on specifying HTTP headers for AJAX calls, but I do not have a piece Think how to do this for a simple async image call. For example, here is a normal AUTO code that is used to display an image on the network:
New AQuery (submodelphoto) .image (MyApplication.MEDIA_BASE_URL + getItem (status), True, truth, 0, r.drawable.default_image); How do I specify an HTTP Referrer for this call? Is it possible to set up to do this for each call during my app? (To do this I have not repeatedly tried to load an image)
after some Excavation (read more) I have come up with this solution:
BitmapAjackCollBack CB = new bitmapAccalbackBack (); Cb.header ("Referrer", "http://www.example.com"); Cb.url (MyApplication.MEDIA_BASE_URL + getItem (status)). Fallback (R.drawable. Default_image) .memCache (true). File cache (true); New AQuery (submodelphoto) .image (cb); It seems to work, just to think that for every request there can be a way to set up the referrer for AQuery.
validation - XML Schema restrictions on the current date -
Is it possible to restrict the date and time data types for the current date XSD? For example, if you want a maximum notification of the date on the current date:
& lt; Xs: element name = "DateOfBirths" type = "date of birth" /> & Lt; X: Simple Type Name = "Date of Birth" & gt; & Lt; Xs: restriction base = "x: date" & gt; & Lt; Xs: minInclusive value = "1920-01-01" /> & Lt; Xs: maxInclusive value = "current-date ()" fixed = "true" /> & Lt; / XS: Ban & gt; & Lt; / XS: simpleType & gt; If the default copy of this copy is not possible, is there an alternate solution? Any help would be appreciated.
XSD does not support XPath functions to set values in proximity, therefore (as That you probably already know) code in the work won in question.
The most obvious solution is
- Use XSD 1.1 and check constraint in one argument.
- Use schematron and check the constraint in a logic.
- Check the barrier at the application level.
-
Announcement of date of birth type is a schema document of its own; From time to time, prepare a new version of that schema document, using the hand or cron job or something similar in today's schema document
& lt; Xs: maxInclusive value = "2013-06-20" /> Will happen. and in the schema document prepared yesterday
& lt; Xs: maxInclusive value = "2013-06-21" /> Will happen.

java - Guide to implementing spring security password recovery with dynamic URL sent to email -
I find it hard to recover passwords, because I have never done such a thing before.
So far I have a web app:
Spring Security, where the password has been properly hacked and the user's roles are fully implemented and work correctly.
The strategy searches with the stack overflow:
- A user hits the forgotten password button, where he enters his email address.
- A dynamic link is sent to the email address
- The user opens the link in the email address >
- who redirects him to the password reset page
Is not known:
- How to link dynamic nature - methods of generation is close to the link - some questions here Met, but often include custom handler or spring security functionality
- such dynamics The request mapping method to answer the link
- temporary link collection methods - databases, sessions, etc.?
As you can see that this list is very serious for any sin, Gle question was then hoping that you could be able to provide guide resources how to do this step Take steps. I was surprised that I could not find a lot on this in the Spring security documentation. Thank you.
I am a student, so in particular in Java context, there are not really the best practices in the industry, so I really hope that anyone can help you. The problem does not really do much with spring security, provided that you configure the user database structure and password encoder. Know how to use it, it is actually implementing only data access, web controllers and an email sender workflow. The link should contain a random token string (for example,
SecureRandom and use a base 64 encoder) and it must be stored in a database with user ID and timestamp (validating that window For which the link is valid). The controller will only remove the token from the incoming request, using the token will load the data from the database. It will check the timestamp and then send the user to the password entry form. Depending on the requirements, you also want them to answer some other security questions. Then you want to validate the passwords and encode it and store it in the reset link table in the account matching the User ID stored in the table. It would also be wise for the batch to remove the link that ends with the database.The Grails Spring Security UI plugin already has an option that you can use directly or use as a reference.
database - Rails, passing an array as criteria to query -
I'm calling the database based on the criteria passed from the scene, so it must be dynamic.
Say I have 2 arrays:
column = ['col1', 'col2', 'col3'] vals = ['val1', 'val2 'Val3'] The query is easy to create, I can concatenation, such as
query = columns [0] + "= ( ?) And "+ .. But what about the parameters?
@finalValues = MyTable.find (: all, terms => [query, wal [0], wall [1] ...]) < / Pre> But I do not know how many parameters I get. Therefore, when the query problem is resolved with the loop and the inclusion, I can do something like this: @finalValues = MyTable.find (: All ,: conditions = & gt; [query, wal]) and the railroad will understand that I am not going to have an array for the IN (?) Segment, but to divide the values for each person (?)
Or is my only option to do a single complete raw string? >
You can create condition as the first element with the query and add all the Vel element to it.
query = columnss.map {| Col | "# {Col} =?"}. Join ("AND") @finalValues = MyTable.find (: All, Conditions => [Queries, * vals]) Point Alignment to Columns and Similar Values Must be number of elements.

c# - HtmlAgilityPack Attributes.Remove on Image Only Removes One, When There Are Two -
I am using in our project, so that we can display any other HTML in our system. I ran into my unit test on this issue, and want to make sure that I am not doing anything wrong if I have an image, and it has 2 "src" values, then I want to choose it, both of them Remove, and add back to the right path once more. I do not think it will be with our HTML, but just in case ....
So, here is an example image tag:
public static string fixHMMLinks (this string html) {var htmlDoc = new HtmlDocument () {OptionWriteEmptyNodes = true}; HtmlDoc.LoadHtml (HTML); Var ImagesToCheck = htmlDoc.DocumentNode.SelectNodes ("// img [@src! = '']"); Var image (var src = image.GetAttributeValue ("src", string.Empty); if (Uri. ISFFMmlRustring (src, UriKind.Relative)) {if the (null! = ImagesToCheck) {foreach (imagesToCheck.ToList ()) { image.Attributes.Remove ( "src"); Image.SetAttributeValue ( "src", Stringkformet (RELATIVE_IMAGE_PROTOCOL_AND_HOST, src));} else if (Urikaisvelafuaruarstring (src, UriKind.Absolute)) {image.Attributes.Remove ( "src"); Image.SetAttributeValue ( "src", src.Replace (ABSOLUTE_IMAGE_HOST_TO_REPLACE, IMAGE_PROTOCOL_AND_HOST));}}} Return htmlDoc.DocumentNode.OuterHtml;} when I debug And this line "removes the image quality." ("Src"); ", there are 2" src "values, as up Damage after the line, although there is one would assume "src", which begins with "/ knowledge", I was asked to summarize the expected removal of them have since been removed:
By removing a feature from the list, using its name. If there are more than one feature by this name, then all of them will be deleted.
I have checked for HtmlAttributeCollection in CodePlex, and remove method takes you through a loop to remove value
I use it wrong Am I doing this, or did I have the opportunity to give a patch to HTMLAgilitpack?
confirmed: image.Attributes.Remove only remove the first event gives. Remove multiple times to call a quick improvement. If it is called and the attribute is not found, then it does not do anything.
You may want to know about it by HtmlAgilityPack authors.

To change the shape, I have to go to vector and change the radius of every planet object there.
Does anyone know how I can do this? Each frame in the display function below draws the planets.

int scale = 1; If (changeScale) scale == 100; Then I will multiply the radius by scale if the changeScale is not set, then the planet should remain in the same size. If changeScale is selected which will grow to 100 in the size of planets. Is there no way in which to accept every planet? If this is not possible, how can I do this to duplicate the planets every frame? I'm not sure how I can modify the object inside my vector. Thank you!
You planet s in your vector Can modify. It will look something like this: planet [index] .mail = new_val; Or, if there are variables, then private and you have accessory methods, planet [index] .setMember ( New_val); So, if you want to change the radius, then it looks like one of the two lower statements:
if (changeScale) {for (Int I = 0; i & lt; Planetary size (); ++ i) {Planets [i] .radius * = 100; // this planet [i] .createdia (planets [i] .getRadius () * 100); // or}} Or, you can use iterator s: if (changeScale) {for (Std :: vector & gt; planet & gt; :: iterator = planetary. BgIN (); it! = Planets.and (); ++ this) {(* this). Radius * = 100; // It (* this) .setRadius ((* this) .getRadius () * 100); //}}}}
