Whatever it does, does not contribute to the proper function of the component. :)

That's what it does.  ShowMessage(TCPClient->Host) creates a blank dialog box.

It would help if that kind of thing were documented..  Oh wait.  
I keep forgetting who this is from. :)

Ok, great.  Dropped the specific assignment of the IOHandler.

Well it apparently can't read your reply because it continues to do it in the
face of your opposition. :)  After leaving IOHandler unassigned, it 
continues to throw exceptions:
Simulator->TCPClient->IOHandler->WriteLn("foo!");
...results in an access violation.


Any suggestions as to how I can actualy make this work?  A C++ example would 
be great. 

I figure I'm either doing something really simple, really wrong, or their
software is terminally broken.  Either way I need it to work as advertised
or I need a pointer to a similar component that will actually WORK with CB2k7.

thanks.
