I have a gallery with many photos. I fill the gallery with AddThumbnail, and use doevents so that the user can watch the gallery being filled and is not bored.
But when he decides to choose a picture (with onclick) during this process, I want to be able to react to this immediately. At the moment I have to wait until the loading process is complete.
Did not try ClsCustomGallery but if thumbnail source is slow , add a holder thumbnail which gets (updated) replaced with the real thumbnail after saving bitmap file .
