I have a question. I have a scanning app that loads an aquired image to a ThumbnailView control. Once the MaxWorkerThreads has been reached, the thumbnails following say "Loading..." and the only way the TthumbnailView gets refreshed is if there is an "out of paper" or some other TWAIN/VRS error. It used to work with Applicaion.DoEvents() coded in, but I want to avoid doing that. Me.Refresh and Thread.Sleep(30) don't seem to be doing it - what am I doing wrong?
