Application.doevents ()

Just do a small map tile download program, originally wanted to add a progress bar to show the progress of the download, but do not know how many pictures, ProgressBar will not be used, so directly added a lable tag count.

Found in the run time, lable tag does not show the results of the real-time display, the mouse drag form program will be stuck, so Baidu a bit, ok,application.doevents () so appear in the eyes, add to the back of the loop, running perfect.

Application.doevents (): Refresh form Information
