Hi All, I have a problem regarding SOAP & ISAPI_Filter. Now, I'm trying to write an ISAPI Filter(Dll), I'd like to call the function of Soap_Server(DLL) via ---.WDSL. But my ISAPI Filter can't CONNECT to Soap_Server. My Soap_Server is for some data manipulation, using MS SOAP Toolkit 2.0 & VC++ 6 . I can call it's functions from other Soap_Client programs(MFC/VB exe). But my ISAPI Filter can't call. So, How can ISAPI_Filter call the functions of Soap_Server? Anyone have the sample code for that? Any article about that? The following Connect() function of ISAPI Filter can't CONNECT to my Soap_Server bool CPlugIn_IIS5Filter::Connect() { HRESULT hr; CString NewWSDL="http://MyWebServer/SoapSvr/MyDBSOAP.WSDL"; if(m_WSDLConnected != NewWSDL) { if (m_pSoapClient != NULL) m_pSoapClient.Release(); hr = m_pSoapClient.CreateInstance(__uuidof(SoapClient)); if(FAILED(hr)) { // DisplayHResult(_T("Cannot create SoapClient."), hr); return false; } try { m_pSoapClient->mssoapinit((LPCTSTR)NewWSDL, _T(""), _T(""), _T("")); } catch(_com_error err) { // DisplayFault(_T("Cannot initialize SoapClient. ")); return false; } m_WSDLConnected = NewWSDL; } return true; } If you have any info, pls forward to me. Any other way to connect Soap_Server? Thanks and best regards Aung aungns@sensecurity.com
