One option: Use a set up gif images and update the image periodically OR Use a canvas and redraw a rectangle slightly larger every time through the scanning loop. The first is easiest the second smoother but much more work! > 2. I got a while loop which does the port scan itself. How can I end > it while its working ? The best way is to have the loop running in a seperate thread to the GUI and checking a flag on each iteration. Then you can have a stop button on the GUI that sets the flag. Its generally a bad idea in a GUI to have long running processes within an event handler, better to put them in a separate thread. Unfortunately this is a lesson that Microsoft's programmers don't appear to have learned yet!
