A program to auto click mouse over top a

Hi all just need alittle help... There is a flash game and I'd like to make an auto mouse clicker program that would in effect click the mouse button after a given amount of time... I want to be able to click on a mouse and release the button, and that when the auto click would happen after a specific amount of time.

Can i use VB to do this or am i wasting my time ?

Thanks

Steve
