WM_MENUCOMMAND message
Sent when the user invokes a command from a menu. See Remarks.
#define WM_MENUCOMMAND 0x0126
Parameters
-
wParam
-
The zero-based index of the item selected.
-
lParam
-
A handle to the menu for the item selected.
Remarks
In most cases, you will listen for the WM_COMMAND message to respond when a user invokes a command in a menu. The WM_MENUCOMMAND message is sent instead of WM_COMMAND only for menus that are defined with the MNS_NOTIFYBYPOS flag set in the dwStyle member of the MENUINFO structure.
The WM_MENUCOMMAND message gives you a handle to the menu so you can access the menu data in the MENUINFO structure and also gives you the index of the selected item, which is typically what applications need. In contrast, the WM_COMMAND message gives you the menu item identifier.
