Hi there .... A ProgressBar in one of my programs get's icreased by one during each loop that is made by a while() loop. If increase the ProgressBar by one until the while reaches 100 (or any other number) the window that contains the loop freezes. How can I keep the window active even when a loop works with the progressbar? with friendly regards.... Jens Luedicke <[EMAIL PROTECTED]> //PGP Public Keys: [EMAIL PROTECTED] <autoresponder>
