Is library running on Citrix or Terminal Server? - Testing on existence/value of environment variable SESSIONNAME - Solution

[bub]

Hi Dough,

We have some personal settings that are saved as txt file in the
application folder.  This folder is shared on Terminal Server so settings
are less personal to say the least.  Even if i move my settings file to a
'home directory', i have issues as they make a kind of group login for
Terminal Server and further user login is through my app.  I am currently
looking into this, i don't know if i can insist with the hosting guys that
all login is 100% individual

All the best
Bruno

hi Phil/Bruno…

Just out of interest……  what reasons make you want to know if you are
running on terminal services???


A number of our customers run under terminal services — and we have had no
reason in the past to want to know.   so the underlying purpose is of
interest to me — in case I should want to know :)

thanks in advance.
