Hi -
I have a piece of Delphi source code here that is calling the 'qwinsta'
utility and parses its output, in order to detect the presence of a Remote
Desktop login session.
This has always worked well on Windows XP (except on some XP-Embedded images
where 'qwinsta.exe' was not pre-installed).
Now I have a new Vista x64 Ultimate system. I have verified that 'qwinsta'
is installed, and it works properly from a command prompt.
However, the routine in my test program fails to access 'qwinsta' - here is
the commandline I use to invoke it:
'cmd.exe /c qwinsta.exe /server'
(this is invoked using CreateProcess) - which returns the following message:
-> "'qwinsta.exe' is not recognized as an internal or external command,
operable program or batch file."
PATH for the system has been set to include %systemroot%\System32, and just
to be sure, I've set the "start in" directory for this command to
c:\Windows\System32 - which is where qwinsta.exe is installed. Using the
same commandline invocation format on the same system, I am able to
succesfully invoke other utilities in the same directory, e.g. SYSTEMINFO.
My account is member of the "Administrators" group, and I've even tried
running the test program "As Administrator" (from the context menu) but no
difference.
I have completely turned off UAC. The last bit of 'relevant' information I
can think of is that all this testing is taking place using a Remote Desktop
connection. The 'qwinsta' output I get from the Command Prompt (i.e.
manually) is as follows:
SESSIONNAME USERNAME ID STATE TYPE DEVICE
services 0 Disc
console 1 Conn
Please, if someone has an idea what I'm doing wrong, let me know!
Also, if there's a better forum somewhere to ask this question - -
TIA, Kristofer
