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.

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)
