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
Called by the framework when the user has clicked the right mouse button (right clicked) in the window. 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.
