Hi,

loRegisterCustomer = loWSHandler.SetupClient("http://domain&5MyUserName:MyPassword@ip address:8081/3connect/services/RegisterCustomerV1?wsdl", "RegistrationCustomerService", "RegisterCustomer")

This should be "http://domain%5cMyUserName:MyPassword@....
(ie %5c as escape character = 5CH = CHR(92) = "\")
It doesn't work as a URL in IE (you'll get a 'Page cannot be displayed') but it should work as a parameter for .SetUpClient()

>>
THIS.wsObject.ConnectorProperty("AuthUser") = "MyUserName"

I believe you said it was not needed but, for reference, if a domain name is required this line should be:
THIS.wsObject.ConnectorProperty("AuthUser") = "DomainName\MyUserName"
