Hello!

Im using OpenGL in a .NET-based application (just for fun). As the title mentions in the following function wglCreateContext returns 0:

private void Form1_Load(object sender, EventArgs e)
{
GL.PIXELFORMATDESC desc = new GL.PIXELFORMATDESC();
desc.nSize = (ushort)Marshal.SizeOf(desc);
desc.nVersion = 1;
desc.dwFlags = (uint)(GL.PixelFormatDesc.PFD_DRAW_TO_WINDOW | GL.PixelFormatDesc.PFD_DOUBLEBUFFER | GL.PixelFormatDesc.PFD_SUPPORT_OPENGL);
desc.iPixelType = (int)GL.PixelFormatDesc.PFD_TYPE_RGBA;
desc.cColorBits = 24;
desc.cAlphaBits = 8; // also tried with 0
desc.cDepthBits = 16;
desc.iLayerType = (int)GL.PixelFormatDesc.PFD_MAIN_PLANE;

hDCWindow = GL.GetDC(panel1.Handle);
int fmt = GL.ChoosePixelFormat(hDCWindow, ref desc);
if (GL.SetPixelFormat(hDCWindow, fmt, ref desc) == 0)
MessageBox.Show(Marshal.GetLastWin32Error().ToString());

hGLRC = GL.wglCreateContext(hDCWindow);
if(hGLRC == IntPtr.Zero)
MessageBox.Show(Marshal.GetLastWin32Error().ToString());
GL.wglMakeCurrent(hDCWindow, hGLRC);

timer.Interval = 22;
timer.Tick += Render;

timer.Start();
}




The errorcode is 2000 (incorrect pixelformat). SetPixelFormat returns true, and fmt is 4.

Isnt OpenGL running in FORMS-based applications?

Greetings
