Get a process's child processes

[Agnes]

Hi,

Is there a way to get the current process's child processes?

Or given a user, get all the processes that are running as that user using
C#?

Thank you in advance!

Agnes

Hello Agnes,

Use WMI

WMI isn't installed by default on Win2003 Server so if that's a target OS
then it's an issue. I'm not sure what C# classes are available for doing
this if any, but the WinAPI is certainly available (e.g.,
"CreateToolhelp32Snapshot()", "EnumProcesses()", etc.)

Not sure where you got this from. WMI is installed per default (more it's a
required service on W2K3 and higher) on W98me, W2K, XP, W2K3, it's an
optional install on NT4 (no longer supported anyway) and W98.

Unless MSFT changed things recently this just isn't the case. On Windows
Server 2003 (not sure about the R2 version), you have to explicitly active
it via "Add/Remove Windows Components" on the "Add or Remove Programs"
panel. I'm certain of this not only having seen official MSFT documentation
on the subject, but having personally installed it many times (the OS itself
that is). WMI was definitely off by default after a fresh install and we
explicitly avoided its use for that reason. This is going back perhaps 1-2
years however but it seems unlikely MSFT would have changed it. If they did
then I stand corrected (though it's still an issue for anyone using the
older versions).

You must be referring to something else I'm afraid, WMI is not an optional
component on WS2003 SP1 and R2, can't check WS2003 pre-SP1 though, but I
don't believe that it was an optional install on WS2003 pre-SP1, since it's
considered a system component on Windows 2000 and higher (up to and
including Longhorn).
The only optional components (for WMI on WS2003) are the WMI SNMP Provider
and the WMI Windows Installer Provider (default on XP). Note that, MSFT
removed the WMI ODBC Adapter and ADSI WMI Provider from WS2003.
