我的COM组件依赖于从Microsoft SOAP工具包3.0（您也可以选择使用SOAP工具包2.0）的SoapClient对象。 SoapClient对象本身是很简单的，但使用它在C + +程序可能会非常棘手，因为它“绑定”在运行时的Web服务。我公司开发的COM组件是包含在XYSoapClient.dll，它使用SoapClient的内部，但更加灵活和强大，并且可以使用C + +程序很容易。你甚至可以在C程序中使用它。最好的部分是，你并不需要生成并编译一个代理类，每次你想使用一个不同的Web服务！

-My COM component depends on the SoapClient object from the Microsoft SOAP Toolkit 3.0 (you may also choose to use Soap Toolkit 2.0). The SoapClient object is pretty simple by itself, but using it within a C++ program can be tricky, because it "binds" to a web service at runtime. The COM component I developed is contained in XYSoapClient.dll, it uses SoapClient internally but is more flexible and powerful, and you can use it easily from C++ programs. You can even use it in C programs. The best part is, you don t need to generate and compile a proxy class, every time you want to use a different web service!
