Unlike regular forms, forms don't expose the MinButton and MaxButton properties and these buttons are always displayed. You can suppress these buttons using the following code: Click here to copy the following block Private Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" _   (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" _   (ByVal hwnd As Long, ByVal nIndex As Long) As Long Const WS_MINIMIZEBOX = &H20000 Const WS_MAXIMIZEBOX = &H10000 Const GWL_STYLE = (-16) Private Sub MDIForm_Load()   SetWindowLong Me.hwnd, GWL_STYLE, GetWindowLong(Me.hwnd, _     GWL_STYLE) And Not (WS_MAXIMIZEBOX Or WS_MINIMIZEBOX) End Sub
