Sounds like you're after a profiler, not a code coverage tool. I think most of them will do what you want.

Another one that's good is Ants from RedGate.

>Thanks Craig. Can the mentioned tools show which lines of code executed without us writing test (I'm using visual studio professional unfortunately)? I have 2 programs that are identical (supposedly), and I need to know if both programs are executing same lines. Bascally need a list of code line number that executed, but willing to use tool that highlight which line of code ran. Again, thanks for all your help
