Add full screen display for MFC applications

Add the following member variables and member functions (using classwizard) in the CMAINFRAME class. The following is the functional description of these variables and functions:

Member variables: BOOL m_bFullScreen; // full screen display signs CRect m_FullScreenWindowRect; // display a full-screen window RectWINDOWPLACEMENT m_wpPrev; // window position is saved for normal view information CToolBar * m_wndFullScreenBar; // full-screen display of a floating toolbar

Member function: void onmenufullscreen (); // full-screen display processing function void onlineMAXINFO (); // Capture the WM_GETMAXMAXINFO message to allow you to add window size void onupdateViewFullScreen (); // Update the Status of the "Full Screen Display" menu
