Ed,
Just a question for clarification. In VFP, when using ActiveX controls, the LockScreen property of the form doesn't work. We have to use the LockWindowUpdate function as well but use the hWnd property of the control. Would this be the same in VB?

>LockWindowUpdate 0 ' Unlock refresh

>>I'm dynamically adding columns to a listview control inside a tab page at runtime that's displaying each column being added. Is there a way to turn off screen refreshes while the columns are being added and only refresh when all columns are added?
