Hi all,

How can I know if the session ID that a certain process is running on is
actually the active session that he consol is connected to. I can get the
session id of a process by

Process P = Process.GetCurrentProcess();

And then check P.SessionID property.

Anyone has an idea?

Thanks

If you are asking whether the process is running under Terminal Services or
local console then: If the SessionID is not 0 then it is running under TS.

HTH

Hi, thanks for the reply. Actually, I want to know if a certain process is
running on the session (desktop) that has the keyboard and mouse. I
understand that there might be more than one user session (using the fast
user switch capability on WinXP) but I want to check for the session with
the user currently interacting with the computer.

I found the function "WTSGetActiveConsoleSessionId" from the terminal
services, but it's an unmanaged code, and I was wondering if there is any
.NET managed way to get the same info.

Thanks for the help,

Thanks for the reply. I tried the PInvoke solution and it works. The
problem it is unmanaged code that need to run in full-trust mode. I was
looking for a managed code solution that would run in a lower privilege.

Cheers
