GetProcessID from Handle

[Cliff Nichols]

I have spent the good part of a day looking for how to get the PID when all I have is a Handle. There seems to be tons of examples how to get the Handle when all you have is the PID, but not the other way around.

So far my best lead is my own code from the Source Code Forum (ok, wo that will be the blind leading the blind, thank god I commented as much as I did). Unfortunately it uses all the "Undocumented" API's

So I wondered if there is a documented and more reliable way to get the PID of a program already running, and I did not start it, but I am looking for it.

Any ideas????

Hence my post of The deceptively-named "GetProcessID" which should be found in Kernel32.dll but I have not found by default any *.inc files that have this???

The docs are elusive to how to declare it if it was an oversight, and Win32Api.inc does not seem to have it, so I thought I would post before complaining some sort of "Bug" when clearly its an oversight

DECLARE FUNCTION GetProcessId LIB "KERNEL32.DLL" ALIAS "GetProcessId" ( _
   BYVAL Process AS DWORD _                             ' __in HANDLE Process
 ) AS DWORD                                             ' DWORD

It needs Windows XP SP1 or greater, and the include files distributed with the compiler are only updated up to Windows 2000.

Win32API.INC is not a valid source for Windows API Information. It is a convenience for users of the PowerBASIC, Inc. compilers. (a LARGE convenience!)
