  • ASP.NET Development Server - Empty webResource.axd after conversion from 2.0 to 3.5

    - by David Casey
    I have moved a project from asp.net 2.0 to 3.5. The original project was using the atlas ajax extensions so I have modified the code to use the built in ajax features in 3.5. When running the project within the dev environemnt (VS2008 on Vista Business SP1) and using the asp.net dev server I receive javascript errors such as WebForm_PostBackOptions which point to a missing handler/module. If I deploy the project and run it stand alone within IIS or if I use Fiddler2 while running in VS2008 I do not see the errors and fiddler shows that the axd files are being downloaded correctly. Also deploying to a 2003 server does not show any issues. I could just carry on and forget this as it works when deployed but I would like to understand what is happening. Has anyone got an ideas as to what is going on here and how to get the same results accross all environments?

  • JavaScript replace with callback - performance question

    - by Tomalak
    In JavaScript, you can define a callback handler in regex string replace operations: str.replace(/str[123]|etc/, replaceCallback); Imagine you have a lookup object of strings and replacements. var lookup = {"str1": "repl1", "str2": "repl2", "str3": "repl3", "etc": "etc" }; and this callback function: var replaceCallback = function(match) { if (lookup[match]) return lookup[match]; else return match; } How would you assess the performance of the above callback? Are there solid ways to improve it? Would if (match in lookup) //.... or even return lookup[match] | match; lead to opportunities for the JS compiler to optimize, or is it all the same thing?

  • Overriding a function in Emacs Lisp

    - by scrapdog
    I would like to temporarily override the kill-new function. I have a way I want to reimplement kill-new that works in only in certain contexts, but I don't want to reimplement a special version of kill-region on top of that. (kill-new is called from kill-region) Since Emacs Lisp uses dynamic scoping, this should be possible, right? (On the other hand, it seems that this would be an unsafe thing to support, and it might make me a bit nervous knowing that it is possible...) I have experimented with using let and fset, but so far have found no way to get it to work as expected. So, hopefully someone can fill in the blank in the following pseudocode: (defun my-kill-new (string &optional replace yank-handler) (message "in my-kill-new!")) (defun foo () (some-form-that-binds-a-function (kill-new my-kill-new) (kill-region (point) (mark)))) What should some-form-that-binds-a-function be? Or am I barking up the wrong tree?

  • Should Java IOException have been an unchecked RuntimeException?

    - by Derek Mahar
    Do you agree that the designers of Java class java.io.IOException should have made it an unchecked run-time exception derived from java.lang.RuntimeException instead of a checked exception derived only from java.lang.Exception? I think that class IOException should have been an unchecked exception because there is little that an application can do to resolve problems like file system errors. However, in When You Can't Throw An Exception, Elliotte Rusty Harold claims that most I/O errors are transient and so you can retry an I/O operation several times before giving up: For instance, an IOComparator might not take an I/O error lying down, but — because many I/O problems are transient — you can retry a few times, as shown in Listing 7: Is this generally the case? Can a Java application correct I/O errors or wait for the system to recover? If so, then it is reasonable for IOException to be checked, but if it is not the case, then IOException should be unchecked so that business logic can delegate handling this exception to a separate system error handler.

  • Set focus and carret position in textarea according to mouse position, as if user had clicked

    - by JeanHuguesRobert
    Once a page with a textarea is loaded, I want some textarea to have the focus immediatly if the mouse cursor is inside that textarea. This is the easy part because a onmousehover handler can set the focus. Now, how to I also set the position of the caret? I would like the caret to be where it would be if the user had clicked using the mouse to set the focus/caret. The basic use case is : User clicks on a link and waits (mouse barely moves) A page is delivered, it contains a big textarea only, full of text User types using keyboard Characters are inserted right below the mouse cursor Today the user has to wait until the caret is visible (at the top left of the textarea) and then click to move the caret before typing. Thanks!

  • JsonResult shows up a file download in browser

    - by joshb
    I'm trying to use jquery.Ajax to post data to an ASP.NET MVC2 action method that returns a JsonResult. Everything works great except when the response gets back to the browser it is treated as a file download instead of being passed into the success handler. Here's my code: Javascript: <script type="text/javascript"> $(document).ready(function () { $("form[action$='CreateEnvelope']").submit(function () { $.ajax({ url: $(this).attr("action"), type: "POST", data: $(this).serialize(), dataType: "json", success: function (envelopeData) { alert("test"); } }); }); return false; }); </script> Action method on controller: public JsonResult CreateEnvelope(string envelopeTitle, string envelopeDescription) { //create an envelope object and return return Json(envelope); } If I open the downloaded file the json is exactly what I'm looking for and the mime type is shown as application/json. What am I missing to make the jquery.ajax call receive the json returned?

  • Asp.Net 3.5 Routing to Webservice?

    - by Maushu
    I was looking for a way to route http://www.example.com/WebService.asmx to http://www.example.com/service/ using only the ASP.NET 3.5 Routing framework without needing to configure the IIS server. Until now I have done what most tutorials told me, added a reference to the routing assembly, configured stuff in the web.config, added this to the Global.asax: protected void Application_Start(object sender, EventArgs e) { RouteCollection routes = RouteTable.Routes; routes.Add( "WebService", new Route("service/{*Action}", new WebServiceRouteHandler()) ); } ...created this class: public class WebServiceRouteHandler : IRouteHandler { public IHttpHandler GetHttpHandler(RequestContext requestContext) { // What now? } } ...and the problem is right there, I don't know what to do. The tutorials and guides I've read use routing for pages, not webservices. Is this even possible? Ps: The route handler is working, I can visit /service/ and it throws the NotImplementedException I left in the GetHttpHandler method.

  • Centralized error handling in VB6.

    - by AngryHacker
    I have the following method that all the error handlers call: Public Function ToError(strClass As String, strMethod As String) As String On Error GoTo errHandle ToError = "Err " & Err.Number & _ ", Src: " & Err.Source & _ ", Dsc: " & Err.Description & _ ", Project: " & App.Title & _ ", Class: " & strClass & _ ", Method: " & strMethod & _ ", Line: " & Erl Err.Clear exitPoint: Exit Function errHandle: oLog.AddToLog "Error in ToError Method: " & Err.Description, False Resume exitPoint End Function It turns out that because I declare an error handler in this function On Error GoTo errHandle, VB6 clears the error before I am able to record it. Is there a way to prevent the 'On Error GoTo errHandle' statement from clearing the error?

  • Authkit - deferring action for HTTP '401' response to client application

    - by jon
    Form, Redirect and Forward all send an unauthenticated user to a Form on a login page specified within an Authkit middleware application. I'd like to allow a client application to request a service via XHR and then present a custom 'client side' form if a HTTP status code of 401 is returned, which would then post to Authkit for authentication until valid authentication/authorization occured. Specifically, 1) a jquery $.get request might request a resource. 2) if an Authkit cookie check confirmed previous authorization the content would be returned. 3) if not I would like Authkit to simply return the '401 response' (and not redirect to another page, or return a form template) where a client side exception handler would notify the user and present an authentication form. Can Authkit work like this?

  • Creating a dynamic (video) Overlay on Google Maps on Android 2.1

    - by Soumya
    I'm trying to create a map overlay for displaying a video stream (MJPEG) on top of a Mapview. Currently I've a standalone activity that creates a data thread for fetching MJPEG video frames. I'm using a handler to send a frame (as a Bitmap) from the data thread to the main activity which then updates the UI. I'm not sure how I can implement "refresh" for updating my "overlayed" video stream. EDIT: What I mean by "refresh" is - how can I update the video portion (not the mapview) of my UI whenever I get a new video frame. I plan to paint the video frame (bitmap) in the "draw method" of my implementation of the Overlay subclass. But the "draw" method is not invoked by me directly. Thanks.

  • Calling Status Bar notification from method from other class.

    - by Jez Fischer
    Firstly, I am new to both android and Java. I have two classes, my main.class and Note.class. I am calling the notification method from my Note.class in my main.class when i press a button. The issue is with this line from the Note.class : PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent); When the method is called it force closes. I believe the problem to be with the "this" in PendingIntent.getActivity(this, 0, notificationIntent, 0);, but I am unsure what to change it to. The notification code works fine if it's in the main class. I would be very grateful for any guidance. Edit: Main class : http://pastebin.com/05Yx0a48 Note.class : package com.adamblanchard.remindme.com.adamblanchard; import com.adamblanchard.remindme.R; import android.app.Activity; import android.app.Notification; import android.app.NotificationManager; import android.app.PendingIntent; import android.content.Context; import android.content.Intent; import android.os.Bundle; public class Note extends Activity { public CharSequence note = "not changed"; int HELLO_ID = 1; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); setTitle("Remind Me!"); } //Notification Method public void callNotification() { // TODO Auto-generated method stub String ns = Context.NOTIFICATION_SERVICE; final NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns); int icon = R.drawable.launcher; CharSequence tickerText = "Remind Me!"; long when = System.currentTimeMillis(); final Notification notification = new Notification(icon, tickerText, when); notification.flags |= Notification.FLAG_AUTO_CANCEL; final Context context = getApplicationContext(); CharSequence contentTitle = "Remind Me!"; CharSequence contentText = note; Intent notificationIntent = new Intent(context, AndroidNotifications.class); PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent); mNotificationManager.notify(HELLO_ID, notification); HELLO_ID++; } } Debug Output : Thread [<1 main] (Suspended (exception IllegalStateException)) Note(Activity).getSystemService(String) line: 3536 Note.callNotification() line: 37 remindme$1$1.onClick(DialogInterface, int) line: 72 AlertDialog(AlertController$ButtonHandler).handleMessage(Message) line: 159 AlertController$ButtonHandler(Handler).dispatchMessage(Message) line: 99 Looper.loop() line: 123 ActivityThread.main(String[]) line: 3647 Method.invokeNative(Object, Object[], Class, Class[], Class, int, boolean) line: not available [native method] Method.invoke(Object, Object...) line: 507 ZygoteInit$MethodAndArgsCaller.run() line: 839 ZygoteInit.main(String[]) line: 597 NativeStart.main(String[]) line: not available [native method] This is the debug output I get, plus a force close popup on the device.

  • How can I set up .Net unhanlded exception handling in a windows service?

    - by Mike Pateras
    protected override void OnStart(string[] args) { AppDomain.CurrentDomain.UnhandledException += new UnhandledExceptionEventHandler(CurrentDomain_UnhandledException); Thread.Sleep(10000); throw new Exception(); } void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e) { } I attached a debugger to the above code in my windows service, setting a breakpoint in CurrentDomain_UnhandledException, but it was never hit. The exception pops up saying that it is unhandled, and then the service stops. I even tried putting some code in the event handler, in case it was getting optimized away. Is this not the proper way to set up unhandled exception handling in a windows service?

  • How to intercept capture TAB key in WinForms application?

    - by Axarydax
    Hi, could you please help me with this one? I'm trying to capture Tab key in Windows Forms application and do a custom action on it. I have a Form with several listViews and buttons, I've set Form's KeyPreview property to true and when I press any other key than tab, my KeyDown event handler does get called. But that's not true with the Tab key - I don't receive WM_KEYDOWN message even in WndProc. Do I need to set each control inside my form - its TabStop property - to false? There must be a more ellegant way that that. Thanks.

  • C#: Windows Forms: Getting keystrokes in a panel/picturebox?

    - by Rosarch
    I'm making a level editor for a game using windows forms. The form has several drop down menus, text boxes, etc, where the user can type information. I want to make commands like CTRL + V or CTRL + A available for working within the game world itself, not text manipulation. The game world is represented by a PictureBox contained in a Panel. This event handler isn't ever firing: private System.Windows.Forms.Panel canvas; // ... this.canvas = new System.Windows.Forms.Panel(); // ... this.canvas.PreviewKeyDown += new System.Windows.Forms.PreviewKeyDownEventHandler(this.canvas_PreviewKeyDown); What is the preferred way of doing this? Can a panel even receive keyboard input? I would like to allow the user to use copy/paste/select-all commands when working with the text input, but not when placing objects in the game world.

  • C#: Two forms, one is calling the other one

    - by Shaza
    Hey all, I have a problem like this, I have two Winforms, f1 and f2. f1 will start a loop on button click, this loop checks a condition and decide to call the other form which is f2 or not. The problem is, the loop may call f2 many times, so each time the other form f2 will be called the first form f1 should pause its execution. So, I solved it like this, I used backgroundWorker + AutoResetEvent. I placed the backgroundWorker in the first form and inside the DoWork event handler I called f2.Show() then I called WaitOne on the AutoResetEvent let it be A. In the other form "f2", on Exiting button I called Set on the same A. But, unfortunately f2 got freezed when clicking that button in f1, what should I change??

  • RichTextBox doesn't update caret position correctly

    - by shadeMe
    I have a handler consuming the keyDown event of a WinForms RTB, that has the following code: GetTextAtLoc(RTB->SelectionStart); // selects some text at the caret's position RTB->SelectedText = "SomeOfMyOwn"; GetTextAtLoc(RTB->SelectionStart); // selects the replacement string RTB->SelectionStart += RTB->SelectionLength - 1; While this code seems to do its job (SelectionStart/Length properties are updated correctly), the caret doesn't move to the end of the new string - It says right where it was at the time of GetTextAtLoc's first call. Redrawing the textbox does seem to have any effect either.

  • How can I pause a BackgroundWorker? Or something similar...

    - by juan
    I was using a BackgroundWorker to download some web sites by calling WebClient.DownloadString inside a loop. I wanted the option for the user to cancel in the middle of downloading stuff, so I called CancelAsync whenever I found that CancellationPending was on in the middle of the loop. But now I noticed that the function DownloadString kinda freezes sometimes, so I decided to use DownloadStringAsync instead (all this inside the other thread created with BackgroundWorker). An since and don't want to rewrite my whole code by having to exit the loop and the function after calling DownloadStringAsync, I made a while loop right after calling it that does nothing but checks for a variable bool Stop that I turn true either when the DownloadStringCompleted event handler is called or when the user request to cancel the operation. Now, the weird thing is that it works fine on the debug version, but on the release one, the program freezes in the while loop like if it were the main thread.

  • Restart IIS7 webapp for debug in VS2008

    - by spender
    I'm developing an ASP.NET asyc generic handler which uses a static System.Threading.Timer instance to feed data to the response output stream while the context is in the asynchronous phase. I'm having issues at startup that I'd like to debug. Currently, because of the long-lived nature of the timer, I'm manually killing w3wp.exe in order to cause the application to restart. I'm aware that there are other ways to do this, but this is the best workflow I can find! Isn't there a way to force a cold start when I hit f5, instead of the standard VS approach of attaching to the existing IIS process?

  • In Clojure - How do I access keys in a vector of structs

    - by Nick
    I have the following vector of structs: (defstruct #^{:doc "Basic structure for book information."} book :title :authors :price) (def #^{:doc "The top ten Amazon best sellers on 16 Mar 2010."} best-sellers [(struct book "The Big Short" ["Michael Lewis"] 15.09) (struct book "The Help" ["Kathryn Stockett"] 9.50) (struct book "Change Your Prain, Change Your Body" ["Daniel G. Amen M.D."] 14.29) (struct book "Food Rules" ["Michael Pollan"] 5.00) (struct book "Courage and Consequence" ["Karl Rove"] 16.50) (struct book "A Patriot's History of the United States" ["Larry Schweikart","Michael Allen"] 12.00) (struct book "The 48 Laws of Power" ["Robert Greene"] 11.00) (struct book "The Five Thousand Year Leap" ["W. Cleon Skousen","James Michael Pratt","Carlos L Packard","Evan Frederickson"] 10.97) (struct book "Chelsea Chelsea Bang Bang" ["Chelsea Handler"] 14.03) (struct book "The Kind Diet" ["Alicia Silverstone","Neal D. Barnard M.D."] 16.00)]) I would like to sum the prices of all the books in the vector. What I have is the following: (defn get-price "Same as print-book but handling multiple authors on a single book" [ {:keys [title authors price]} ] price) Then I: (reduce + (map get-price best-sellers)) Is there a way of doing this without mapping the "get-price" function over the vector? Or is there an idiomatic way of approaching this problem?
