Stopping events from being processed

[YiDing]

Hi,

I'm trying to do some type ahead searching. Each search operation is
rather expensive however, so I would like to be able to deactivate/stop
etc, the events that were raised previously. Is there any way I could
do this?

Thanks,
Yi

In addition to my previous question, I am also experiencing an issue
when scrolling through a listview. In this case, it seems like .NET
cannot process the events fast enough and therefore there are keyboard
events long after the user has lifted his hand from the key down
button. Is there a way to work around this?

Thanks,
Yi
