Getting RAM usage of system processes (Windows)
Posted: Fri Mar 08, 2024 8:28 pm
In my app, I need to get the RAM usage of some processes, including system ones. I currently have this code. It works on some processes, but a pretty frustratingly small subset, even when running as administrator. What's the proper way to do this? I found a couple code samples here, but they were all old and used functions my PB couldn't find 
Thanks!
Code: Select all
Procedure GetRAMUsage(PID)
Protected PMC.PROCESS_MEMORY_COUNTERS
Protected Process = OpenProcess_(#PROCESS_ALL_ACCESS, #False, PID)
If Not Process
ProcedureReturn -1
EndIf
Protected Result = -1
If GetProcessMemoryInfo(Process, @PMC, SizeOf(PROCESS_MEMORY_COUNTERS))
Result = PMC\WorkingSetSize
EndIf
CloseHandle_(Process)
ProcedureReturn Result
EndProcedure
