Hi There

I want to stop all paiting on a form while I do some processing.

SuspendLayout and ResumeLayout does not seem to work, and after digging
around, I found that I needed to make an interop call to
LockWindowUpdate.

Is there a better way ?

Thanks
Bill
 
Only the ListView and TreeView controls have the BeginUpdate/EndUpdate
methods. For others, you have to resort to P/Invoke.

P/invoke with 'SendMessage' + 'WM_SETREDRAW' ;-).
