If the CWnd object is associated with a menu, OnMenuSelect is called by the framework when the user selects a menu item.

afx_msg void OnMenuSelect( 
   UINT nItemID, 
   UINT nFlags, 
   HMENU hSysMenu  


Identifies the item selected. If the selected item is a menu item, nItemID contains the menu-item ID. If the selected item contains a pop-up menu, nItemID contains the pop-up menu index, and hSysMenu contains the handle of the main (clicked-on) menu.


Contains a combination of the following menu flags:

  • MF_BITMAP   Item is a bitmap.

  • MF_CHECKED   Item is checked.

  • MF_DISABLED   Item is disabled.

  • MF_GRAYED   Item is dimmed.

  • MF_MOUSESELECT   Item was selected with a mouse.

  • MF_OWNERDRAW   Item is an owner-draw item.

  • MF_POPUP   Item contains a pop-up menu.

  • MF_SEPARATOR   Item is a menu-item separator.

  • MF_SYSMENU   Item is contained in the Control menu.


If nFlags contains MF_SYSMENU, identifies the menu associated with the message. If nFlags contains MF_POPUP, identifies the handle of the main menu. If nFlags contains neither MF_SYSMENU nor MF_POPUP, it is unused.

If nFlags contains 0xFFFF and hSysMenu contains 0, Windows has closed the menu because the user pressed the ESC key or clicked outside the menu.

Note Note:

This member function is called by the framework to allow your application to handle a Windows message. The parameters passed to your function reflect the parameters received by the framework when the message was received. If you call the base-class implementation of this function, that implementation will use the parameters originally passed with the message and not the parameters you supply to the function.
