web services - How can I connect to a webservice through winIntet library in c++? -


i created webservice seems that:

[webservice(namespace = "http://tempuri.org/")] [webservicebinding(conformsto = wsiprofiles.basicprofile1_1)] // allow web service called script, using asp.net ajax, uncomment following line.  // [system.web.script.services.scriptservice] public class webservice : system.web.services.webservice {      public webservice()     {          //uncomment following line if using designed components          //initializecomponent();      }      [webmethod]     public string helloworld()     {         return "hello world";     } }

the service reference http://localhost:4653/webservice.asmx.

now, need access webservice through cpp project. that, i'm using wininet library way:

hinternet handle = internetopen("upload", internet_open_type_direct, null, null, 0); if (handle) {     hinternet handleconnect = internetconnect(handle, "localhost:4653", internet_default_http_port, null, null, internet_service_http, null, null);     if (handleconnect)     {         if (hinternet handleopenreq = httpopenrequest(handleconnect, text("post"), text("/webservice.asmx/helloworld"), null, null, null, internet_flag_keep_connection, 0))         {             if (httpsendrequest(handleopenreq, null, 0, null, 0))                 cout << "succeed" << endl;             else             {                 dword p = getlasterror();             }         }

however httpsendrequest not succeed , getlasterror returns 12029, i.e attempt connect server failed. how can fix problem, connect webservice? there parameters sending wrong? thanks,

instead of using internetconnect, try use internetopenurl()
