Create a dedicated "control" window for the OpenGL rendering. Register this as custom control and put that into the dialog.

At least, that's how I remember, how it's done. It's been 20 years since I've used OpenGL together with the MFC.

Why are you using the MFC at all anyway, they've been deprecated for ages.
