Question

How can I create a VB6 client connect to WCF web service?

Is there any better solution to create web service instead of using WCF, so that it is lot more easier to connect from VB6?

Answer 1

You can find articles on writing a SOAP client in VB6 – such as this one

I would make some suggestions for you to look at alternative client or web-service technologies:

1. Why go for a different web service technology in order to write the client in a 10 year old technology. I used to be a VB6 programmer, so I’m not anti it – but it seems a strange design choice to engineer a different service, for the purpose of using quite an old client technology. You must have your reasons, but I’d just like to challenge them a bit.
2. I’ve written a WCF client application recently – using an auto-generated proxy in c# – worked fine. That said, a REST architecture for a web service is sometimes a little easier to understand and may be an alternative that would work better with VB6. Does your web service have to use a SOAP like architecture?

My recommendation is that if you are stuck with VB6 – and flexible for the web-service end – have a look at a REST architecture. If you want to go down the SOAP way – WCF has worked great for me, and you should be able to get something to work in VB6, but I would look for articles about using SOAP with VB6, as there will not be many about VB6 and WCF.
