I made a simple vb.net application that does this; download a file to c:\2312.tmp, read the content, delete the file in a forever while 1 loop. My form completely freezes, with me.refresh I can get the labels refreshed, but moving the form is impossible. System.Threading.Thread.Sleep(1000) didnt helped, so how can fix this so it wont freezes the form while doing the forever looped function ?

Hi Octalys;

It sounds like you will need to add a statement like the following in the while loop.

        Application.DoEvents()

This will allow the program to handle other events such as paint and mouse move and many others.

Thanks for the answer, it works alot better, still abit laggy but atleast I can move the window abit and click on stop :)

If the loop takes a long time to complete 1 loop you may try putting more then one DoEvents at different locations in the loop.
