The Web Service Definition Language (WSDL) provides standard standards for services.

In soap, soap Toolkit and the Visual Studio. NET IDE perform similar functions. The difference is that the SOAP Toolkit object does not provide all the support the Visual Basic developer needs. In Figure 2, you can see intellisense® support (Visual Basic programmers think this kind of support is necessary). The IntelliSense drop-down
