[THIN] Re: NT4+Citrix Development Question

I have to agree. It sounds much more like an NT4 / W2K incompatibility issue
and they just don't want to fix it. I do a fair bit of application
development and I've never come across any differences between the TS API
and the Citrix APIs. Citrix has a wider range but it doesn't redefine any of
the TS calls, just adds new ones.

Quite vague...

Since you are on NT4 and they just released the update, I'll skip the normal
"a desktop program doesn't run under terminal services" stuff.

A problem with "system calls" often involves calls to the Windows Native
API, which changed in some incompatible ways between NT and the more recent
OS's.  It would be unusual for an application program to use the Native API
instead Windows API, which would be compatible - but who knows?  Assuming
that their software was working on NT prior to the upgrade, it really isn't
that hard to make it work both ways -- however they probably have no
incentive to do so.  By the way, I am unaware of anything Citrix would be
doing to cause a "system call" issue.

There's not been many dev questions, but hopefully someone might have some
experience on this..

We're working with a company called Star who have recently released an
update to their time and fees software which falls over horribly on
NT4+Citrix (we use 1.8). Through various other contacts of theirs, they've
managed to narrow the problem down to being the fact that Citrix apparently
doesn't handle the system calls (specifically as to what users are online)
as well as plain TS does, somehow..

A bit vague I know, but is anyone able to shed even a tiny ray of light?
