Question elapsed time calculation b/w two click events

[chandrubngit]

I have a start button, pause button and end button.when user clicks on start button the timer should start, when they press pause button,

timer should pause and should able to store the elapsed time in terms of minutes...later again if the user press the resume button (the same

pause button) the timer should continue from the elapsed time..finally after clicking end button the total duration of the elapsed time (before

pause and after resume click events) in minutes should get stored in access database field..

I need to do this in vb.net 2003 with access database 2003...

thanks a lot for ur valuable suggestion....

regards
