You should use the BeginUpdate() and EndUpdate() methods. It would help here...

Simply using them would test the patience of the user. Then the ListView will only update when search has finished.
We'll have to set it to update after every 100 or so results.

But those are extra perks which I've left for the programmer to figure out. This thread basically shows how to do a file search and grab icons of the files to show them as if in Explorer.
