thx a lot.
well on my side,i've made use of a variable,incrementing it by 20 at each "timer interval".it worked but the problem is that only 3 bars are appearing on the progress bar.do I need to make use of a loop here so as it continues up to 100%?
You need to provide a bit more detail but I dont think there is any real need of using a timer just to update a status bar.
For example if your looping thru rows in a returned dataset or lines in a file, you want to start by simply setting the max value to your total count. Then within your loop increment each itteration by 1.
If you are unaware of count or how long something will take to process you can set the progress bar state to marquee which will give an non-stopping animation which you can deactivate when completed.
