Help - my VB.net form goes "blurred" when performing a large if the user switches to another windows application

How do I avoid this as the form makes the program look like it has crashed  (after it goes blurred) until it finishes the active and appears correctly.

Thanks

Hi rwallacej,

If the activity is a loop then you can use application.doevents inside the loop to allow the processor to be freed up during the cycles of the loop. This will allow the form to repaint. Alternatively you can start your activity on a seperate thread which will have a similar effect.

The BackgroundWorker control (.NET Framework 2.0) gives you easy asynchronous capability with Windows Forms.
