VC MFC Webservices

1：先安装soapsdk3.0(http://download.microsoft.com/download/2/e/0/2e068a11-9ef7-45f5-820f-89573d7c4939/soapsdk.exe)
2：当然就是写代码

{

  WSWrapper wsWrapper("http://www.coopur.com/WebServiceDrawMoney.asmx",

        "SubmitInfo"
  );//当然是调用WSWrapper.cpp，其中http://www.coopur.com/WebServiceDrawMoney.asmx是服务器端给的webservice地址。"http://tempuri.org/"是命名空间，默认的命名空间都是此地址。SubmitInfo是服务端的方法名，与客户端无关

    string strName1 = "11,大大,s,dds";  //这个消息是要发送给服务端的，消息的格式是由服务端处理数据得要求决定的，本公司是要发送用户名，密码等四条信息，我以逗号分隔，服务端以逗号分隔处理数据
