Put simply as possible, I have an SDI application in which, on a certain menu command, I want to pop up another frame window which displays some information. &nbsp;I have derived my own class from CFrameWnd, implemented a simple message map which handles WM_PAINT, and added a constructor which calls the Create() and ActivateFrame() functions. &nbsp;Then, I added a menu command and a handler in my view class which creates a new object of my class. and what do I get? nothing! not a single pixel. &nbsp;What exactly am I missing here?
