I'm trying to use TIdTCPClient directly and not in association with any form.
I'm using (or trying to) it within another class.

My class constructor goes something like this:

void __fastcall classSimulator::InitCommSystem() {
    busy = true;
    TCPClient = new TIdTCPClient(this);
    IOHandler = new TIdIOHandlerStream(NULL);
    TCPClient->IOHandler = IOHandler;
    TCPClient->OnDisconnected = MainForm->DisconnectHandler;
    busy = false;
}

Now the line:
TCPClient = new TIdTCPClient(this);
Dies during compile because "Could not find a match for TIdTCPClient::
TIdTCPClient(classSimulator* const)", which is perfectly reasonable.
That's why I'd changed it from "this" to NULL like the IOHandler below it.

Now while calling it with (NULL) compiles, it doesn't actually appear to work.

When I do this:
TCPClient->Host = "localhost";
TCPClient->Port = 5500;

and then 

ShowMessage(TCPClient->Host);

The dialog shows nothing.

I can call TCPClient->Connect() and get no exception, yet 
TCPClient->Connected() returns false.

Calling TCPClient->IOHandler->Connected() (or anything else under 
TCPClient->IOHandler) just pitches an access violation exception.

What do I need to do in order to make this thing work?

thanks all

g.
