OpenGL wglCreateContext fails when rendering onto a bitmap when not having rendered onto a window first

Hi,

I'm having a frustrating problem with the wglCreateContext call. I'm using DirectX for rendering on screen, and I'm using OpenGL to render the same thing onto a bitmap (for printing). When not using DirectX, the OpenGL bitmap creation works fine, but when using DirectX, the wglCreateContext call fails and GetLastError returns 8 ("Not enough storage is available to process this command"). Anybody got any thoughts on this A number of calls are succeeding before this call fails: getting the screen DC, CreateDIBSection, SetPixelFormat all succeed.

All help is appreciated!

You are very unlikley to get a good answer here especially now that you've identified that DirectX doesn't cause the issue.

Try http://www.opengl.org/cgi-bin/ubb/ultimatebb.cgi if you haven't already done that.

I'm just getting more insight in what the problem is. It doesn't have to do anything with DirectX, the problem seems to be trying to render on a bitmap, without having used OpenGL for rendering on the screen. I just created a small test console program to try and do OpenGL rendering on a bitmap, and it gives the same error.

Some more details:
OS: Windows XP Pro, graphics card NVIDIA GeForce 7600 Go (512 Mb memory).

Digging further!!!
