Catching cassia errors in VB 2010
Robert Gijsen
I've written a tool for non-admin users to be able to remote-assist
other users based on permissions per group, rather than per server.
Works great for what I want. To be able for Cassia to read/enumerate a
Terminal Server the user needs at least the 'query information'
permission on the RDP listener. Now when a user doesn't have that,
Visual Basic 2010 which I use crashes in an unhandeld exception.
A very basic 'proof of concept':
Dim TSManager As New TerminalServicesManager()
Dim TSServer As ITerminalServer
Dim TSSession As ITerminalServicesSession
Dim numberofsessions as integer
TSServer = TSManager.GetRemoteServer(<TSservername which you
don't have access to>)
TSServer.Open()
NumberOfSessions=TSServer.getsessions.count
This would create an exception in the last line. That's not a problem
as that user is actually not allowed to enumerate that info. But how
do I catch that error from VB? It doesn't generate an error in err.
Any help is appreciated.

Are you using the legacy On Error statement in VB.NET? If so, try using a Try/Catch block instead. The exception thrown by Cassia will be of type Win32Exception.

Guess I stared blind on this one. Thanks a lot!
