I have an important technical query about COM....
I have a small project which requires some work to finish it off.
The scenario is as follows:
I have a VB6 application on server A (it has to be a VB6 app because it has
to respond to a DDE request) which needs to launch an application on server
B.
The application on server B is also a VB6 application and uses COM to
communicate with a third application on server B. The third application on
Server B has a GUI which is required to be displayed to the user on server
A. so far I have embedded a MSRDPCLIENT object in the application on server
A, which successfully launches the application on server B.
The problem comes when a new request is received by server A. The embedded
MSRDPCLIENT object only seems to have a disconnect function which doesn't
end the session on sever B - meaning that a new connection request creates a
new session - this eats up server resources and will bring server B to a
halt very quickly. What I need is a way of communicating to the already
established session, telling it of a revised parameter and allowing the
existing session to do it's stuff.
My research has led me to believe that there is something called
VirtualChannels which would allow this communication to take place, though I
am unsure if this is the case or not.
Hope you can help.
Thanks,
Darren
