Called by the framework when the user has clicked the right mouse button (right clicked) in the window.
afx_msg void OnContextMenu(
   CWnd* pWnd,
   CPoint pos 
);
Parameters
- pWnd 
 Handle to the window in which the user right clicked the mouse. This can be a child window of the window receiving the message. For more information about processing this message, see the Remarks section.
- pos 
 Position of the cursor, in screen coordinates, at the time of the mouse click.
Remarks
You can process this message by displaying a context menu using the TrackPopupMenu.
If you do not display a context menu you should pass this message onto the DefWindowProc function. If your window is a child window, DefWindowProc sends the message to the parent. Otherwise, DefWindowProc displays a default context menu if the specified position is in the window's caption.
