a.) Pay Attention what happens if you press button1_Click more than one time...you should fix this also.
b.) Set ProgressBar's Maximum to your Counter value (which you have declared twice, you should also fix this).

I'd suggest you post that as a solution - it's the right approach!

Also beware in the Eventhandler method, counter--; could go below 0.
