How to profile a piece of code? VS2013 C++

Question

I can profile the complete application by clicking "Actions, Start profiling" in performance explorer.

But I wish to profile only a piece of code, so I followed this answer and came up with this code:

StartProfile(PROFILE_PROCESSLEVEL, PROFILE_CURRENTID);
testcode();
StopProfile(PROFILE_PROCESSLEVEL, PROFILE_CURRENTID);

so I use the "Start With Profiling Paused" but the profiler never starts profiling.

I've tried all levels (PROFILE_GLOBALLEVEL, PROFILE_PROCESSLEVEL and PROFILE_THREADLEVEL) - none of them work.

Any ideas?
