Hi, I'm new with VB. NET but I have been using GL and C++ for 10 years.
I installed OpenTK. The thing is that VB .NET can't compile my code because it says it can't recognize SwapBuffers.
Can some tell me what I need to #include?
Or perhaps a sample project, an example, anything at all.
Thanks in advanced.
PS : I'm using Visual Studio 2010 Express.
Opengl And Visual Basic .Net
1. Have you added OpenTK as a reference?
2. You say it doesn't recognize 'SwapBuffers', of what class?
3. You did add a statement like 'Imports OpenTK' ?
3. Could you show us the code? this might help us.

The code is short since I just started.
"2. You say it doesn't recognize 'SwapBuffers', of what class?"
I come from a C++, VB6, Win32 API, MFC, OpenGL. SwapBuffers is a windows API function. It is in gdi32.dll
I don't know how things are done in VB.NET, that's why I ask.
