VB6 in ASP.NET Web Service

If you were to do this whole thing yourself, you would have to use the Win32 API socket functions to establish a socket connection to the server, send a request, then receive the response. You would also have to generate the request to send and process the response you get back using an XML DOM implementation. I recommend using a prebuilt solution. The first choice for non-.NET-enabled environments and older compilers without new SOAP support seems to be the Microsoft SOAP Toolkit version 3. This is a COM implementation that works with VB6.
