Popup windows with CFrameWnd
I'm using the MFC CFrameWnd class as the base class for the main window of my application, an OpenGL based scenegraph viewer (OpenSceneGraph, specifically). I'm creating the window as a popup window (WS_POPUP), as that is the convention I've seen used everywhere for Windows 3D graphics. The problem is that the window is created with a border, which is something I don't want. I've tried specifying ~WS_BORDER as a dwStyle parameter for the Create method, but this simply causes the window to fail to show altogether. Anyone know of a way to get rid of the border, or do I need to use a different base class?
