MFC & OpenGL

I would like to create a MFC App that use an OpenGL window in a Mfc Dialog. I have found a good example at:

http://www.steinsoft.net/index.php?site=Programming/Projects/OpenGL/opengldialog

However i would like to include a drop menu in the window. Can someone help me ?

I tried to create an SDI and used CFormView as base class but i am now stuck.

You will find information about this in the MFC documentation or at msdn.microsoft.com
