Hi All,

I have successfully implemented the progress bar example below but would like to eliminate the need for the start button !

I would like the progressBar to start as soon as the application is launched & close when the progress bar has been completed ??

Is this possible ? Can you please give a little detialed answers of how to implement this please ?

Many thanks in advance,

Fassage
