Answer 1

You might be able to use some of the suggestions from this question (if you don't mind using Win32 calls).

Answer 2

I found the soln.
1. Get handle of parent window A.
PerformanceCounter perId = new PerformanceCounter("Process", "Creating Process ID", Process.GetCurrentProcess().ProcessName);

2. Use GetLastActivePopup method to get last active popup (Last popup works in my case :) ) .
