Screen Flicker 1

[RobS23]

I have a form containing 2 list boxes. These list boxes are being regularly updated. I need to try and stop the nasty flickering as they are repopulated. In Access there is the Echo method, which allows the screen updating to be turned off and back on after an operation is completed.

Can someone tell me the VB equivalent?

Here is one solution using the LockWindowUpdate API.


Put this declaration at the top of a module to make it global:

Public Declare Function LockWindowUpdate Lib "user32" (ByVal hwndLock As Long) As Long


To turn off refresh:

LockWindowUpdate frmWhatever.hWnd

To turn it back on:

LockWindowUpdate 0
