Remote Desktop)?
Thanks,
franc

Check this:

How can my script / application detect if it is running in a Terminal
Services client session?

Re: How to check if a program runs unter terminal services?

Thank you Vera, that works:

BOOL bIsRemoteSession = GetSystemMetrics( SM_REMOTESESSION );

By the way, the GetSystemMetrics is in user32.dll

Yours,
franc
 
Re: How to check if a program runs unter terminal services?

And is there a way to prevent that a programm asks the user32.dll about
GetSystemMetrics( SM_REMOTESESSION )?
 
Re: How to check if a program runs unter terminal services?

I have no idea if/how to do that.
Just curious, but why would you want to prevent this?

Re: How to check if a program runs unter terminal services?

Some programs use this function to verify for not allowing to run under
shared environment
like TS for licensing purpose. Probably he wants to bypass this check to
make the software
can run under a remote session.

Re: How to check if a program runs unter terminal services?

Yes, that were my thoughts as well, Thomas, but I wasn't as brave
as you and didn't dare to ask in plain text if this was the reason
:-)

Ha ha ha, because you are a celebrity here, in these newsgroups and on the
net
but I'm not ;-), nobody know who am I, although I have been in these groups
since 2001 :-)

Yes, it's just like Thomas said:
there is a program, that needs a (very expensive) supplement-license
(only for the printing-engine) if it runs under TS.
So i have to use UltraVNC, but TS is more comfortable, therefore i am
looking for a trick to avoid this check.
Thank you anyway, Vera.

Regards, franc
 
Re: How to check if a program runs unter terminal services?

There is a way to do that, you have to use injecting technic to
inject your code into memory space of the program and check
if the function is called, but it required a good skill

But thank you, Thomas!
