My code is the same with your code except (Environment.Exit(0); (I dont have this code) it works with this code but without it I got this message of e.ExceptionObject

System.ArgumentException: for test
at ConsoleApplication1.Program.Main(String[] args) in c:\users\apple\documents\visual studio 2010\Projects\Mydynamic\Mydynamic\Program.cs:line 17

and it shows this window

Close the program

when I click on the "Debug the problem" item, visual sutdio Just In-Time debugger asks "Do you want to debug using the selected debugger?" after yes it goes to my code exception details are

System.ArgumentException was unhandled

That is pretty much what I would expect. If you don't have the exception handler cause an program exit, then the system has no choice except to cause an abnormal termination - which is what your message shows.

Think about it: the exception is thrown from the Main method. The application cannot continue under any circumstances without restarting the whole program.

In Winforms et al., it is multithreaded, so a single thread can be terminated without necessarily killing the whole app - but your console app is a single thread. If it can't continue the only running thread, it can't continue the application.
In GUI apps, the Main function is executed in a thread, which fires off other threads to handle the UI for each form. They can be terminated without affecting the Main thread, since all it is doing is waiting for the others to die anyway! Laugh | :laugh:

}

static void MyException(object sender, UnhandledExceptionEventArgs e)

}

Works for me; displays the exception with the custom text in the console, and then switches to the debugger. What did you expect it to do, and what behaviour are you observing?

Doesn't contain much hints on what went wrong. I hope you're logging the full text of the exceptions?

Looks like it's (also) being run from Visual Studio, debugging on it's C-drive.

That seems to work as expected; the AppDomain-handler correctly gets the message and processes it. And no, it doesn't prevent the app from closing - you'll have to fix the exception.

Hello,

The problem is, when I run a method from other form (example: From form1 I call form2.mymethod) , it show me error in MessageBoxManager.cs
in:
hHook = SetWindowsHookEx(WH_CALLWNDPROCRET, hookProc, IntPtr.Zero, AppDomain.GetCurrentThreadId());

How can I solve this ?

Best regards

Disable the hook when debugging. It's not even related to the error you are reporting.

Why are you using AppDomain.GetCurrentThreadId()?? That's been obsolate since .NET 2.0 because it doesn't return the correct ID in all cases.

Any why are you setting this hook at all??

Hi, i'm trying to get OpenCvSharp runing and i couldn't manage to make it work. Google tutorials haven't help, or i just can't get it right. Anyone that can help me installing and a basic tutorial?

I'm trying to make my program recognize a PS3 Eye (hopefull could choose in the differents resolutions settings), and show live video.

What makes you think my tutorials are better than those of Google? What does "couldn't manage to make it work" mean? Did you get an exception, some kind of error? Did the library not compile?

Those from google are probably the same ones you or anyone here post, i just can make them work i think. Whenever i want to run a code for recognizing camera, an error pops about the P/invoke. Give me 3 possible solutions, but non of them of my understanding.

OpenCV's DLL files exist in the same directory as the executable file....
Visual C++ Redistributable Package has been installed....
The target platform(x86/x64) of OpenCV's DLL files and OpenCvSharp is the same as your project's....

Maybe i got a wrong OpenCvSharp.dll

The problem with other tutorials is that they'll use a comparable technique, and you'd be running into the same wall.

If the PC is 64 bits, might be a conflict with incompatible versions. What did the P/Invoke exception say?

Tehn you don't need MDI as it stands for MULTIPLE Document Interface. A single editor that let's you edit mulitple documents of the same type. That was it's intended design and you would be trying to make it do something it's NOT designed to do.

You don't need MDI for this and from the sounds of it, you don't even need a Windows Forms app.

Drawing a 3D polygon from coordinates (KML)

tokano13-Oct-12 5:20

13-Oct-12 5:20

Hello all!

I have to draw a 3D terain (polygon) using openGL and Tao Framework in C#. The problem is, i have never done such things before and i dont know how to start. I have my KML file and i wonder, how to read data or use coordinates, to draw a 3D terain of the path i've walked (or drove with a car).

Can anyoone give me any advice or help how to start making the 3D object of it?

Thnx.

The point of the program is, to create a 3D polygon which can rotate around, so i could see in 3D where i walked, if u can understand what i mean with that.

The thing was told to be 'easy' to make.

Any help given, will be apreciated, like your reply. Thnx.
