Hi, I''m using OpenGL in a win32-DLL (Visual C++6) to create a window and display some polygons. I''m not using the glMainLoop because I have my own loop to draw (I repaint the polygons in the WndProc of the OpenGL window that I have created - with CreateWindowEx -). The problem is that is painted. My Draw routine does like this: ClearGLScene(); ... glBegin(GL_POLYGON); .... glVertex3d(x,y,z); ... glEnd(); glFlush(); SwapBuffers(hDC); ... I''ve done it before in a different DLL but I don''t know why in this one doesn''t work. Please, if you have any idea, tell me before I throw the PC out of the window... Thanx all, guille

I don;t really understand what the problem is.. are the polygons not rendered?

It might be a bit massive, but you could check out the DemoGL sourcecode (www.demogl.com/sourcecode.asp) which renders opengl based effects from a dll on a window that is created by that DLL. But perhaps if you explain your problem a bit more I''m able to answer it right away
