I run emacs on windows. I use cygwin and I have cygwin versions of ruby and rdebug installed as well. When I invoke M-x comint-run ENTER rdebug ENTER, I noticed that it is attempting to run rdebug.bat via the Microsoft Command prompt, instead of using bash to run rdebug (without the .bat). I'd like comint-run to use bash to invoke any pr...

Hi everyone. I'm having trouble emitting a call to a delegate whose type is unfinished at the time of the emit. I'll elaborate: I've declared the following delegate type: // Delegate type. The 'firstArgument' will be 'this', i.e., this is an open // instance method: the implicit argument is here given explicitly, in // 'firstArgument'. ...
I'm building a WPF application. I'm doing some async communication with the server side, and I use event aggregation with Prism on the client. Both these things results in new threads to be spawned which are not the UI thread. If I attempt to do "WPF operations" on these callback and event handler threads the world will fall apart, which...
In my WPF application I communicate asynchronously with a server. The callback will hence not be run in the UI thread, and as I need to do some WPF stuff there (create InkPresenter object) I need it to be run on the UI thread. Well, actually the requirement is that it is run on a thread with STA apartment mode. I tried creating a new thr...

I'm creating a system that takes readings from a hardware device that sends data via a serial port. Every time a "packet" comes in off the serial port, I update and redraw some GUI components to reflect the updated information. Since serial port events stem from a separate thread, I have to call Invoke(Invalidate) on several components t...
I've run into another problem using C# 4.0 with optional parameters. How do I invoke a function (or rather a constructor, I have the ConstructorInfo-object and I know it doesn't require any parameters, but I still can't invoke it. Here is the code I use now: type.GetParameterlessConstructor().Invoke(BindingFlags.OptionalParamBinding |...
There's a bug in delphi 6 which you can find some reference online for when you import a tlb the order of the parameters in an event invocation is reversed. It is reversed once in the imported header and once in TServerEventDIspatch.Invoke. you can find more information about it here: http://cc.embarcadero.com/Item/16496 somewhat rela...
I've got the following code: Public Delegate Sub SetStatusBarTextDelegate(ByVal StatusText As String) Private Sub SetStatusBarText(ByVal StatusText As String) If Me.InvokeRequired Then Me.Invoke(New SetStatusBarTextDelegate(AddressOf SetStatusBarText), StatusText) Else Me.labelScanningProgress.Text = StatusText ...
What is the best way to accomplish this: The main thread (Thread A) creates two other threads (Thread B and Thread C). Threads B and C do heavy disk I/O and eventually need to pass in resources they created to Thread A to then call a method in an external DLL file which requires the thread that created it to be called correctly so only T...

With the help of people on stackoverflow I was able to get the following working code of the simples GUI countdown (it just displays a window counting down seconds). My main problem with this code is the invokeLater stuff. As far as I understand the invokeLater send a task to the event dispatching thread (EDT) and then the EDT execute t...

Hi everyone. First of all, sorry if this has been asked before. I've done a pretty comprehensive search and found nothing quite like it, but I may have missed something. And now to the question: I'm trying to invoke a constructor through reflection, with no luck. Basically, I have an object that I want to clone, so I look up the copy co...
Not sure what I'm doing wrong: class MyClass { private EventInfo eventInfo; public void OnGenerateEvent(object sender, EventArgs e) { // Called from *main* thread // Load assembly and set eventInfo here eventInfo = ....GetEvent(...); eventInfo.AddEventHandler(source, handler); //...
I'm working on a heavily data-bound Win.Forms application where I've found some strange behavior. The app has separate I/O threads receiving updates through asynchronous web-requests which it then sends to the main/GUI thread for processing and updating of application-wide data-stores (which in turn may be data-bound to various GUI-eleme...
