Removing the Control Menu and Application Window Controls

MORE INFORMATION

Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. You can use the following sample macro in conjunction with workbook protection, full-screen display, and a custom menu bar to remove the window controls on a Microsoft Excel workbook. The macro limits a user's ability to control the window by removing the maximize and minimize buttons and the window's control menu box, and by disabling the application switching keystrokes.

Macro Example

'Macro To Protect the Workbook and Limit User Control
'
Sub WbProtect()

     'Trap for the ALT+F4 (close application) key combination
     Application.OnKey "%{f4}", ""

   ' Note that if you are using Microsoft Excel for Windows 95,
   ' you are unable to override CTRL+ESC, ALT+TAB, and ALT+ESC.

     'Trap for the CTRL+ESC, ALT+TAB and ALT+ESC
     '(application switching) key combinations
     Application.OnKey "^{esc}", ""
     Application.OnKey "%{esc}", ""
     Application.OnKey "%{tab}", ""

     'Turn on error handling in case the Menu bar already exists
     On Error Resume Next

     'Make sure Microsoft Excel is Maximized
     Application.WindowState = xlMaximized

     'Make sure the workbook is maximized
     ActiveWindow.WindowState = xlMaximized

     'Protect the window
     ActiveWorkbook.Protect Structure:=True, Windows:=True
     With ActiveWindow
          .DisplayHorizontalScrollBar = False
          .DisplayVerticalScrollBar = False
          .DisplayWorkbookTabs = False
          .DisplayHeadings = False
     End With

     'Set the application to full screen view
     Application.DisplayFullScreen = True

     'Create a new blank menubar
     MenuBars.Add "mybar"

     'Show the blank menu bar
     MenuBars("mybar").Activate

End Sub
