Lockscreen

[Zach Ahmed]

Hi All:
Is there a similar function to Lockscreen in VB? In VFP you could use Lockscreen when the code needs to refresh lots of text boxes or comboboxes. The Lockscreen prevent screen flickering. I was wondering if there is a similiar function in VB.

Thanks

There isnt one built in, but it is easy to use the Windows one, all it takes is a simple API call. Unfortunately only one window can be locked at a time, but you wont get errors if it fails (you just wont get the locking effect).

'Add this to the declarations section of a form/module:
Declare Function LockWindowUpdate Lib "user32" Alias "LockWindowUpdate" (ByVal hwndLock As Long) As Long
 
 
'Usage:
             'Lock
  LockWindowUpdate Me.hWnd
 
             'Unlock
  LockWindowUpdate False
