关于soap的问题

Question

ISoapConnectorPtr pConnector;
pConnector.CreateInstance(__uuidof(HttpConnector));
在这里pConnector无法CreateInstance成功，pConnector总是为空，小弟搞SOAP新手，请大家帮忙解决一下。
详细代码参考http://blog.chinaunix.net/u2/68374/showart.php?id=703924

Answer 1

#import "msxml3.dll"
using namespace MSXML2;#import "C:\Program Files\Common Files\MSSoap\Binaries\MSSOAP1.dll" \
   exclude("IStream", "ISequentialStream", "_LARGE_INTEGER", \
    "_ULARGE_INTEGER", "tagSTATSTG", "_FILETIME")
using namespace MSSOAPLib;void CallService()
{
   ISoapSerializerPtr pSerializer;
   ISoapReaderPtr pReader;
   ISoapConnectorPtr pConnector;
   pConnector.CreateInstance(__uuidof(HttpConnector));
}
