I am using vb.net 2003.

How can i make a count down in vb.net?

I am using 2 textboxes and a timer and a checkbox.

TxtHours , Txtminutes

It should work like this that if user enter 0 in hours and 5 in minutes box and as soon user will select checkbox then it will start cont down.

00:05:00
00:04:59
00:04:58

Thanks in advance
