Call webservice in VB6 or ASP

Webservice is called in VB6 or ASP.

Web Services enables data sharing and communication between heterogeneous computing environments to achieve information consistency. We can use
Http post/GET and SOAP protocols are used to call Web Services.

1. Use the SOAP protocol to call Web Services in VB6

First, use. net to publish a simple Web Services.
<WebMethod ()> _
Public Function getString (ByVal str As String) As String
Return "Hello World," & str &"! "
End Function
This Web service only contains one getString method, which is used to return a string. When we call this Web Services, the SOAP message sent to the. asmx page is:
<? Xml version = "1.0" encoding = "UTF-8"?>
<Soap: Envelope xmlns: xsi = http://www.w3.org/2001/XMLSchema-instance
Xmlns: xsd = "http://www.w3.org/2001/XMLSchema" xmlns: soap = "http ://
Schemas.xmlsoap.org/soap/envelope/ ">
<Soap: Body>
<GetString xmlns = "http://tempuri.org/TestWebService/Service1">
<Str> string </str>
</GetString>
</Soap: Body>
</Soap: Envelope>
The returned SOAP message is:
<? Xml version = "1.0" encoding = "UTF-8"?>
<Soap: Envelope xmlns: xsi = http://www.w3.org/2001/XMLSchema-instance
Xmlns: xsd = "http://www.w3.org/2001/XMLSchema" xmlns: soap ="
Http://schemas.xmlsoap.org/soap/envelope/>
<Soap: Body>
<GetStringResponse xmlns = "http://tempuri.org/TestWebService/Service1">
<GetStringResult> string </getStringResult>
