Addresses the issue of opening a view in maximized mode the proper way in MFC.
Override CFrameWnd::ActivateFrame and pass SW_SHOWMAXIMIZED to the base class function.
 
Code:
class CChildFrame : public CMDIChildWnd
{
// ...
   // Overrides
   // ClassWizard generated virtual function overrides
   //{{AFX_VIRTUAL(CChildFrame)
   public:
   virtual void ActivateFrame(int nCmdShow = -1);
   //}}AFX_VIRTUAL
// ...
};
 
void CChildFrame::ActivateFrame(int nCmdShow) 
{
// TODO: Add your specialized code here and/or call the base class
    if (nCmdShow == -1)
    {
        // Show the window in maximized mode 
        // if and only if it is the very first frame
        // Otherwise, do default for user conveniences
        // The user may prefer to keep a previously created view and 
        // frame in restored (not maximized) mode
        // So, it is advisable to keep the newly created view and frame 
        // in the same state as already created views
        if(GetNextWindow() == NULL && GetNextWindow(GW_HWNDPREV) == NULL)
        {
            nCmdShow = SW_SHOWMAXIMIZED;
        }
    }   
   CMDIChildWnd::ActivateFrame(nCmdShow);
}
