五：本文示例的SOAP代码：

#include <stdio.h>
　　
#import "msxml3.dll"
using namespace MSXML2;
　　
#import "C:Program FilesCommon FilesMSSoapBinariesMSSOAP1.dll"
exclude("IStream", "ISequentialStream", "_LARGE_INTEGER",
"_ULARGE_INTEGER", "tagSTATSTG", "_FILETIME")
using namespace MSSOAPLib;
　　
void main()
{
　CoInitialize(NULL);
　　
　ISoapSerializerPtr Serializer;
　ISoapReaderPtr Reader;
　ISoapConnectorPtr Connector;
　　
　// 连接服务器
　Connector.CreateInstance(__uuidof(HttpConnector));
　Connector->Property["EndPointURL"] = "http://www.allesta.net:51110/webservices/soapx4/isuseronline.php";
　Connector->Connect();
　　
　// 启动消息机制
　Connector->Property["SoapAction"] = "uri:allesta-YahooUserPing";
　Connector->BeginMessage();
　　
　// 创建SoapSerializer对象
　Serializer.CreateInstance(__uuidof(SoapSerializer));
　　
　// 与输入流连接
　Serializer->Init(_variant_t((IUnknown*)Connector->InputStream));
　　
　// 制作SOAP信息
　Serializer->startEnvelope("","","");
　Serializer->startBody("");
　Serializer->startElement("isuseronline","uri:allesta-YahooUserPing","","m");
　Serializer->startElement("username","","","");
　Serializer->writeString("laghari78");
　Serializer->endElement();
　Serializer->endElement();
　Serializer->endBody();
　Serializer->endEnvelope();
　　
　// 向服务器发送信息
　Connector->EndMessage();
　　
　// 读取回应
　Reader.CreateInstance(__uuidof(SoapReader));
　　
　// 连接输出流
　Reader->Load(_variant_t((IUnknown*)Connector->OutputStream), "");
　　
　// 显示结果
　printf("Answer: %sn", (const char *)Reader->RPCResult->text);
　　CoUninitialize();
}
