时间:2008-04-17

声明:

Private Declare Function GetSystemMenu Lib "user32" Alias "GetSystemMenu" (ByVal hwnd As Long, ByVal bRevert As Long) As Long

Private Declare Function DeleteMenu Lib "user32" (ByVal hMenu As Long, ByVal nPosition As Long, ByVal wFlags As Long) As Long

Private Declare Function GetMenuItemCount Lib "user32" (ByVal hMenu As Long) As Long Private Const MF_BYPOSITION = &H400&

使用:

Private Sub Form_Load()

Dim hwndMenu As Long
Dim c As Long
hwndMenu = GetSystemMenu(Me.hwnd, 0)
c = GetMenuItemCount(hwndMenu)
DeleteMenu hwndMenu, c - 1, MF_BYPOSITION
c = GetMenuItemCount(hwndMenu)
DeleteMenu hwndMenu, c - 1, MF_BYPOSITION
End Sub
