I have made a wrapper with OpenGL. I'm trying to make a font wrapper as well, but to select the font in order to convert it for use with OpenGL, I have to have the HDC variable. That variable is created and used in the OpenGL window wrapper and I really don't want the two classes communicating, nor do I want to have to pass the HDC from the calling function(usually WINMAIN) into the setup function of the font. Is there a way to get the HDC value. I have seen GetModuleHandle(), but when you use a NULL argument to that function, it returns the HINSTANCE. That would work, if using the HINSTANCE, I could get the HDC. Can this be done or will I have to pass the HDC into the setup function? Thanks in advance.

I'm not really sure what you are doing but how about using a global HDC and GetDC(). However, I have a feeling that this is a horrible idea.

Well, the hwnd argument for the GetDC function is in the same class as the DC I'm trying to get. Though I just had an idea. I think maybe OpenGL itself has a function to get the DC. I'll try the OpenGL forum if I can't find it. Thanks for the help. I tried the GetDC with a NULL, but that didn't work.

Actually, I looked in the wgl functions that make OpenGL connect with windows. There is a function to get the current HDC their and it worked. Thanks for the help.
