MSSOAP Toolkit v3 using SSL in VC 6 throwing exceptions.

[Trips]

Hi,
Firstly if this isnt the place to post this question, kindly point me to the right place and ill bother them with my problems

I am developing an application to consume a XML/SOAP service provided by a 3rd party, so there really isnt any scope for changing/testing anything at the server end (although i do access to a development/test server, but not to any source code etc).
I am writing the client in VC++ 6, (Visual Studio 6.0) and before everyone says why not use .Net, it just isnt an option, so I have to use VC++ 6. I am using the MSSOAP Toolkit v3.0. The client machine is a Windows XP Desktop and the webserver hosting the
service is running IIS on and XP desktop install (the server OS will probably be different in the wild).
The problem I am having is the service can be accessed using normal http, with no encryption/authentication and also using Server Side SSL Certs, but no client certs or client authentication (so SSL is being used purely for encryption, not validation). Everything
appears to work correctly when using plain http, but when using https I get an E_INVALIDARG exception/_com_error thrown.

Here is the abbreviated source code to make the connection and call to the service:

<div style="color:Black;background-color:White; <pre>

As you can see from the code, this is being run inside its own thread, but i dont think this should create the problem I am seeing here.
The code gets as far as sending, the request, but fails when trying to create a SoapReader30 object and attach it to the output stream of the connector (HttpConnector30) object.

Once again, I realise that im being forced into using out of date libraries, etc... but like most devs, I dont really get a say in that.

If you need more information to help me then please ask.
