I don't mean to post this again but no one is giving me what i need, so can someone please give me some code to disable the control panel through api? (and code to bring it back again of course) I downloaded a code tutorial on how to do this, even a demo project, but it doesn't work, this is very frustrating. Any help would be much appreciated, thanx!

Function RegQueryStringValue(ByVal hkey As Long, ByVal strValueName As String)

Dim lResult As Long

On Error GoTo 0

Usage


Private Sub Command1_Click()

'Save a Value to the Registry
savestring HKEY_CURRENT_USER, "Software\Myapp", "Testing", "Hello"

End Sub

Private Sub Command2_Click()

'Get a value from the Registry
Retval = GetString(HKEY_CURRENT_USER, "Software\Myapp", "Testing")
Print Retval

End Sub
