Specialised task manager
-
I was thinking of creating a simple, specialised task manager. It seems quite easy to use the Diagnostics.Process class to get processes memory and CPU usage. But I also need to get GDI and USER objects per process. Is there any similar class for that or is it performance counters or WMI I need to look into?

Hi Heath, thanks for your answer. I did look into the performance objects in PerfMon (I have a XP Home WS at home and a Win2K WS at work) and could not find any counters for the process object. Actually I could not find any counter for this. I have looked with exctrlst.exe and could not find any disabled counters. So I have to ask if you can point me in the right direction on how to proceed: 1. Do I have to do something to add more counters to the process object (or they might just not are available in WS PerfMon). 2. Is there any other performance object I should look into (but I still want the count per process as in the Task manager).

If you can't find performance counters that suit your needs, you'll need to P/Invoke native APIs when appropriate, like
GetPerformanceInfoorGetProcessMemoryInfo, both defined in psapi.dll on XP and newer. I recommend reading the native performance monitoring and Processes sections of the Platform SDK at http://msdn.microsoft.com/library[^]. The .NET BCL by no means provides a full set of diagnostic APIs for issues like this. This posting is provided "AS IS" with no warranties, and confers no rights.
