 WM_MENUCOMMAND

The WM_MENUCOMMAND message is sent when the user makes a selection from a menu.

Syntax

    WM_MENUCOMMAND
        WPARAM wParam
        LPARAM lParam;

Parameters

• wParam
  Specifies the zero-based index of the item selected. Windows 98/Me: The high word is the zero-based index of the item selected. The low word is the item ID.
• lParam
  Handle to the menu for the item selected.

Return Value

No return value.

Remarks

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.

The WM_MENUCOMMAND message is sent only for menus that are defined with the MNS_NOTIFYBYPOS flag set in the dwStyle member of the MENUINFO structure.

Notification Requirements

• Minimum DLL Version None
• Header Declared in Winuser.h, include Windows.h
