Toggling DWORD values in the registry

[paddydog]

I have managed to hide the address bar in IE8 by under HKEY_CURRENT_USER>Software>Policies>Microsoft adding the keys Internet Explorer> Toolbars> Restrictions> and then a DWORD entry NoNavBar.

If I set the DWORD value to ‘1’, hey presto, no address bar! If you then set the DWORD value back to ‘0’ the address bar re-appears.

I would like to be able to have a button on the desktop to toggle the DWORD value between '0' and '1' and a friend suggested VB which I know nothing about.

Anyone got any ideas?

Thanks

Private Const HKEY_CURRENT_USER = &H80000001
Const ERROR_SUCCESS = 0&
Const ERROR_BADDB = 1009&
Const ERROR_BADKEY = 1010&
Const ERROR_CANTOPEN = 1011&
Const ERROR_CANTREAD = 1012&
Const ERROR_CANTWRITE = 1013&

Const HKEY_LOCAL_MACHINE = &H80000002
Const REG_SZ = 1

Private Const REG_DWORD = 4
Dim nBufferKey As Long
Dim nVal As Long

First Function ::

Sub Hide_Drive(strDrv As String)
    RegOpenKey HKEY_CURRENT_USER, "SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\", nBufferKey

    RegSetValueEx nBufferKey, "NoNavBar", 0, REG_DWORD, nVal, Len(nVal)
    RegCloseKey nBufferKey
End Sub

Note : In Above code will add the Dword Value accordingly to what to hide the nav bar .
