GetSystemMenu

  • Article

This function is implemented as a macro to maintain compatibility with existing code. Use the menu handle returned by this macro to disable the Close button. There is no other use for the return value.

HMENU GetSystemMenu(
  HWND hWnd, 
  BOOL bRevert 
);

Parameters

  • hWnd
    [in] Handle to the window that will own a copy of the window menu.

  • bRevert
    [in] Boolean that specifies the action to be taken. If this parameter is FALSE, GetSystemMenu returns the handle to the copy of the window menu currently in use. The copy is initially identical to the window menu, but it can be modified.

    If this parameter is TRUE, GetSystemMenu resets the window menu back to the default state. The previous window menu, if any, is destroyed.

Return Values

If the bRevert parameter is FALSE, the return value is the handle to a copy of the window menu. If the bRevert parameter is TRUE, the return value is NULL.

Remarks

Use the following code to disable the Close button.

EnableMenuItem (GetSystemMenu(hwnd, FALSE), SC_CLOSE,MF_BYCOMMAND | MF_GRAYED);

Requirements

OS Versions: Windows CE 1.0 and later.
Header: Winuser.h.
