Answer 1

This will happen when your program quits too soon, before the profiler had a chance to collect any samples. Perhaps somewhat typical when you kick the tires to see how it works but haven't written any real code yet that can be profiled in a meaningful way.

For very short programs with little actual code, be sure to change the profiling mode. Use Analyze + Performance Wizard and switch from "sampling" to "instrumentation" mode. Instrumentation mode slows down the program a great deal but is a lot more accurate for very short programs.

Answer 2

Are you sure the process is still running when the profiler starts? Looking at the message about the process ID not being valid, it sounds like the process might have exited before the profiler had a chance to collect anything.
