Windows Performance Analysis Tool usage as a profiler

Question

I have an application written in c++ using visual studio 2005. The application has certain performance problems. I would like to explore where. I need to drill down in which classes/methods/lines the application spends most of the time. Can this be done with the WPA? If yes, can you, please give me a pointer to documentation?

No, WPT leverages windows events, it would only help you diagnose a problem when Windows is the cause of your slow-down. You certainly won't get any diagnostics for your code. What you need is a real profiler. Good ones cost money. Check this thread for more advice.
