用SOAP调用WEB SERVICE问题 [复制链接]

请问各位老大：
使用SOAP调用WEB SERVICE时调用mssoapinit函数的时候返回错误信息查看msdn是参数不对代码如下：

ISOAPClient *pSoapClient;

::CoInitializeEx(NULL,COINIT_MULTITHREADED);
HRESULT hr = CoCreateInstance(CLSID_SoapClient,NULL,CLSCTX_INPROC_SERVER,
IID_ISOAPClient,(void**)&pSoapClient);

BSTR bstrWSDLFile(L"http://192.168.1.14/firstwebservice/service.asmx?WSDL");

hr = pSoapClient->mssoapinit(bstrWSDLFile,CComBSTR(L""),CComBSTR(L""),CComBSTR(L""));

//出现的错误：0x80070057L
