we have an windows XP embedded machine ( single session workstation )

This should only allow 1 session however when
Using WTSGetActiveConsoleSessionId this returns a value of 2.
How can this be?
I am logging in via RDP starting a process.
This process is returning my session = 2.
So I then cancelling it. becasue this is a non console session id.
Since the workstaion only takes 1 session.

How to ensure that my task is running on the systems consolesession.

Kind Regards,

RObert.

OK I have solved it.

After searching everywhere and finding nothing.

Step 1. Call kernel32.dll -> WTSGetActiveConsoleSessionId  to get
console session id.
Step 2. use jedi library function jwsclToken.JwGetProcessLogonSession
to get process session id.
Step 3. if( console session = process session ) or ( process session
is zero )then VICTORY!!!!

2 days of in depth searching to get the result.

Glad you solved it and that you documented the result here to save the
next unfortunate soul with this problem 2 days of searching.

Note: if you don't get any useful responses here, you can also try
asking in the FPC mailing list (or Lazarus mailing list).
