    In code or just for you?

    For you you can do it using the Task Manager (at least in the NT family).

    You have to use WMI calls - download WMI from:

    You might want to check if there is some CPU hog in your app.

    good point, but most programmers with my experience(Posts: 445) will know how to find that out. especially with my assembly knowledge, you get to know several opcodes that can find that out for you as well as taskmanager.
