QTP - Controlling if a date is later than another one

Hello everyone!

I'm writing a lot of scripts these days at work but now I'm stuck...

Basically I need to analyze a parameter (a String) and see if the date it contains is later than another one...

I know it could be a "nooby" question, but the fact that the parameter is a string and the control is on a date totally confuses me...

Is it something as simple as: if parameter("DataAct") > 01/01/2010 ?!?!
