Note In Microsoft Excel 2002, you do not need the FindWindow or GetActiveWindow API statements as in earlier versions of Excel because the Application object has a new Hwnd property. Declare Function GetSystemMenu Lib &quot;user32&quot; (ByVal hwnd As Long, _  ByVal bRevert As Integer) As Integer

Declare Function DeleteMenu Lib &quot;user32&quot; (ByVal hMenu As Integer, _  ByVal nPosition As Integer, ByVal wFlags As Integer) As Integer Private Declare Function SetWindowLong Lib &quot;user32&quot; Alias _ &quot;SetWindowLongA&quot; (ByVal hwnd As Long, ByVal nIndex As Long, _     ByVal dwNewLong As Long) As Long

Private Declare Function GetWindowLong Lib &quot;user32&quot; Alias _ &quot;GetWindowLongA&quot; (ByVal hwnd As Long, ByVal nIndex As Long) _ As Long

Const WS_MINIMIZEBOX = &H20000 Const WS_MAXIMIZEBOX = &H10000 Const GWL_STYLE = (-16)

'The following procedure makes the window control menu unavailable.

Sub Disable_Control Dim X As Integer For X = 1 To 9 'Delete the first menu command and loop until 'all commands are deleted. Call DeleteMenu(GetSystemMenu(Application.hwnd, False), 0, 1024) Next X

End Sub

'The following procedure restores the control menu. 'Note that to run this procedure, the Declare statements above 'must be in the module.

Sub RestoreSystemMenu 'restore system menu to original state hMenu% = GetSystemMenu(Application.hwnd, 1)

End Sub

'The following procedure makes the Minimize and Maximize commands 'on the window control menu, and the Minimize and Maximize window 'control buttons in the upper-right corner of the Excel window unavailable.

Sub HideMinimizeAndMaximizeButtons Dim L As Long

L = GetWindowLong(Application.hwnd, GWL_STYLE) L = L And Not (WS_MINIMIZEBOX) L = L And Not (WS_MAXIMIZEBOX) L = SetWindowLong(Application.hwnd, GWL_STYLE, L)

End Sub

'The following procedure restores the Minimize and Maximize commands on the 'control menu, and the Minimize and Maximize window control buttons 'in the upper-right corner of the Excel window.

Sub RestoreMinimizeAndMaximizeButtons

Dim L As Long L = GetWindowLong(Application.hwnd, GWL_STYLE) L = SetWindowLong(Application.hwnd, GWL_STYLE, WS_MINIMIZEBOX _     Or WS_MAXIMIZEBOX Or L)

End Sub The commands on the control menu are numbered, starting at zero. The default control menu items are as follows: Restore is item 0, Move is item 1, Size is item 2, Minimize is item 3, Maximize is item 4, and Close is item. Even if items are deleted, the first item always starts at 0 (zero).

To delete individual items from the control menu without deleting the whole menu, you can specify the menu command to delete. For example, the following two lines of code, when used instead of the For ... Next loop in the Disable_Control macro, delete the Maximize (item 4) and Minimize (item 3) commands and also disable the Maximize and Minimize buttons: Call DeleteMenu(GetSystemMenu(Application.Hwnd, False), 4, 1024) Call DeleteMenu(GetSystemMenu(Application.Hwnd, False), 3, 1024)
