• I can't get ExternalInterface.addCallback to work - trying to call an AS3 function from a js button

  - by Guillaume Riesen

  I'm trying to use ExternalInterface.addCallback to allow js to call an as3 method. My code is as follows: AS: ExternalInterface.addCallback("sendToActionscript", callFromJavaScript); function callFromJavaScript():void{ circle_mc.gotoAndStop("finish"); } JS: Switch to square function callToActionscript() { flashController = document.getElementById("jstoactest") flashController.sendToActionscript(); } It's not working. What am I doing wrong?

• NServiceBus specify order of Handlers execution

  - by John Simons

  Just wondering if this is the way to specify the order to run a handler (AuthorizationHandler) before all others? public void SpecifyOrder(Order order) { order.Specify(First<AuthorizationHandler>.Then<IHandleMessages<IMessage>>()); } It just feels odd to add Then<IHandleMessages<IMessage>>(). Is there a nicer way of saying to the Bus execute x handler before all others?

• WPF textbox derived control override drag&drop OnPreviewDrop (C sharp)

  - by Petr Klus

  Hi, I have been working on my custom control derived from the TextBox and I have encountered a problem I can not solve right now. Brief description of the problem: my textbox contains plain text which contains tags which I want to keep consistent - so far I have overriden text selection so they can be selected only as a whole tag etc. Right now I have moved to processing of drag&drop. If any text is dropped on the textfield and it is dropped on the tag, I want the insertion to be moved before or after the tag. The actual problem is with setting of the e.Handled=true. If I set it to true, it almost works - the text is inserted via my routine, but it is not removed from the source. If I set it to false, after executing my method the original textbox's insertion method is run. Is there any way to alter event routing? Or am I approaching this wrong from the start? Code of my method: protected override void OnPreviewDragEnter(DragEventArgs e) { base.OnPreviewDragEnter(e); e.Handled = true; // let us draw our very own caret... } protected override void OnPreviewDrop(DragEventArgs e) { base.OnPreviewDrop(e); fieldsReady = false; int selStart = this.SelectionStart; int selLength = this.SelectionLength; string droppedData = (string)e.Data.GetData(DataFormats.StringFormat); // where to insert Point whereDropped = e.GetPosition(this); int droppedIndex = GetCharacterIndexFromPoint(whereDropped, true); if (droppedIndex == this.Text.Length - 1) { double c = GetRectFromCharacterIndex(droppedIndex).X; if (whereDropped.X > c) droppedIndex++; } // only if the source was us, do this: if (this.SelectionLength > 0) // this means that we are dragging from our textbox! { // was there any selection? if so, remove it! this.Text = this.Text.Substring(0, selStart) + this.Text.Substring(selStart + selLength); e.Handled = true; // 2DO!! alter the indices depending on the removed selection // insertion this.Text = this.Text.Substring(0, droppedIndex) + droppedData + this.Text.Substring(droppedIndex); } }

• When inheriting a control in Silverlight, how to find out if its template has been applied?

  - by herzmeister der welten

  When inheriting a control in Silverlight, how do I find out if its template has already been applied? I.e., can I reliably get rid of my cumbersome _hasTemplateBeenApplied field? public class AwesomeControl : Control { private bool _hasTemplateBeenApplied = false; public override void OnApplyTemplate() { base.OnApplyTemplate(); this._hasTemplateBeenApplied = true; // Stuff } private bool DoStuff() { if (this._hasTemplateBeenApplied) { // Do Stuff } } }

• What hack can I use to suppress an unused function warning?

  - by Yuval A

  Consider a private method which is called from JNI and not used otherwise, generating a compiler warning about an unused method: private void someMethodCalledOnlyFromJNI() { // WARNING: method is never used // .... } This is some legacy code in Java 1.4 - so no dice on @SuppressWarnings. What hack would you use to suppress this compiler warning?

• slowing down a loop in a recursive function

  - by eco_bach

  I have a difficult problem with a recursive function. Essentially I need to 'slow down' a for loop within a function that repeatedly calls itself(the function); Is this possible, or do I need to somehow extract the recursive nature of the function? function callRecursiveFuncAgain(ob:Object):void{ //do recursive stuff; for (var i:int = 0; i < 4; i++) { _nextObj=foo callRecursiveFuncAgain(_nextObj); } }

• CodeMirror 2 - (readonly and editable code)

  - by Happy Hacking

  Can CodeMirror 2 be used to set part of the code to be uneditable? I do not wish to do it like fully editable code. Example: Code inline: example public static void main(String args[]){ //content } I hope to be able to make Line 1 and 3 uneditable BUT able to edit lines in between them adding characters/spaces increasing the number of lines inside the method as we speak AND still unable to edit the starting and closing bracket lines.

So every time I change the function name or add a new argument to the function, I have to go back the the .h file to do the same. Is there a VIM plugin that can automate this task?

• Linking a Text Box to a variable?

  - by cam

  I would like to have direct access to the text inside a textbox on another form, so I added a public variable _txt to a form and added an event like so: private void richTextBox1_TextChanged(object sender, EventArgs e) { _txt = richTextBox1.Text; } But the form is loaded like this: public FrmTextChild(string text) { InitializeComponent(); _txt = text; richTextBox1.Text = _txt; Text = "Untitled.txt"; } Is there a better way to directly link the two?

• Determining if types alias to the same underlying type in C++

  - by emchristiansen

  I'd like to write a templated function which changes its behavior depending on template class types passed in. To do this, I'd like to determine the type passed in. For example, something like this: template <class T> void foo() { if (T == int) { // Sadly, this sort of comparison doesn't work printf("Template parameter was int\n"); } else if (T == char) { printf("Template parameter was char\n"); } } Is this possible?
