I Have a simple OpenGL program using MFC that works in an SDI environment. I am trying to port it to an MDI environment without much success. Can anyone recommend a good tutorial or example shell program that uses openGL in an MDI environment, and give me advice on setting it up, or flame me and tell me that this is a bad idea ? I am trying to create a simple drawing program that uses one window like a floating tool box or palette, and allows the user to draw on the main area. Again, as I am new to MFC am I doing the right thing, or is there a much better / more elegant way of creating a program like this ? Thanks in Advance.
