I would like to determine the process id of the parent process for an arbitrary process in Windows.

I need this method to work on both x64 and x32.

Any ideas / sample code to make this happen. System.Diagnositics.Process does not include this info.

I am a bit worried about using the toolhelp apis cause they are 32 bit specific.

The Performance counter solution in the FAQ: (PerformanceCounter(‘Process’, ‘Creating Process ID’, procName);) scares me, cause it does not allow you to enter a process id, instead you specify a process by name so it all can go pear shape when you have multiple children.

  1. WIN32_Process has processid and parent processid. Getting the WMI data on 64-bit is a bit more difficult, but still possible by changing the provider flags.
