OpenGL used in a subsection of an MFC CDialog

[PeterK]

I am trying to create a dialog using Visual C++ that has a small OpenGL "window" embedded inside it.

I have succeeded in enabling OpenGL to draw to the entire window but I want to confine it to a small subsection (so that MFC controls most of the dialog's background).

Is there a simple way of doing this?
Is ActiveX the answer?

OK, that can be tricky....

You should create a new class and use it as a custom control in your dialog box....

Concerning this new class you would create, you then have to put all your OpenGL inits in this class instead of in the CDialog-derived class of your application...

I know that can sound a bit messy but I assumed there that you are familiar with MFC and class-derivation...

Of course, you can also create an ActiveX control for this purpose but this is REALLY tricky (I have just finished one for my viewer...).

Make any control-element with an own DC.
You are able to render to all "elements" with an own DC in it. Modify the size of the DC, to the size you want.
