opengl causing c# application to close

[supagu]

i have a c++ dll in which i call
SDL_SetVideoMode with the flag:
SDL_OPENGL to init opengl for me.

Now i'm using this c++ dll in a c# project i create my opengl window/device then at the end of the c# method it closes the c# application (calls Dispose method, where normally it would call my paint method)

any ideas? maybe sdl is setting opengl up incorrectly for window mode for me or somehting?

Well, are you entering any message loop after you open the window ?

okay i debugged the sdl dll, and seems the problem is that they are making a temporary window init some OGL stuff then destroy the window. When this temporary window is destroyed it doing something bad in c# and then my c# application ends up calling dispose.

is there maybe a way i can hack things to dispose doesnt get called. ie. maybe unregister it with garbage collector while it sets up my engine window?

Not sure whether you've managed to solve your problem or not, but thought I'd mention this OpenGL wrapper for C#, which I've used for several projects. Its quite handy, doesn't require any additional DLLs or files, just a few .cs files to add to your project.

Of course, it is no use if you want to use SDL for more than just graphics, but its a good resource nonetheless.
