   #include <Winhttp.h>
   
   
   using namespace std;
   
   void main()
   {
   WINHTTP_CURRENT_USER_IE_PROXY_CONFIG MyProxyConfig;
   if(!WinHttpGetIEProxyConfigForCurrentUser(&MyProxyConfig))
   {
   //check the error
   DWORD Err = GetLastError();
   cout << "WinHttpGetIEProxyConfigForCurrentUser failed with the following error number: " << Err << endl;
   switch (Err)
   {
   case ERROR_FILE_NOT_FOUND:
   cout << "The error is ERROR_FILE_NOT_FOUND" << endl;
   break;
   case ERROR_WINHTTP_INTERNAL_ERROR:
   cout << "ERROR_WINHTTP_INTERNAL_ERROR" << endl;
   break;
   case ERROR_NOT_ENOUGH_MEMORY:
   cout << "ERROR_NOT_ENOUGH_MEMORY" << endl;
   break;
   default:
   cout << "Look up error in header file." << endl; 
   
   }//end switch
   }//end if
   else
   {
   //no error so check the proxy settings and free any strings
   cout << "Auto Detect is: " << MyProxyConfig.fAutoDetect << endl;
   if(NULL != MyProxyConfig.lpszAutoConfigUrl)
   {
   wcout << "AutoConfigURL is: " << MyProxyConfig.lpszAutoConfigUrl << endl;
   GlobalFree(MyProxyConfig.lpszAutoConfigUrl);
   }
   if(NULL != MyProxyConfig.lpszProxy)
   {
   wcout << "AutoConfigURL is: " << MyProxyConfig.lpszProxy << endl;
   GlobalFree(MyProxyConfig.lpszProxy);
   }
   if(NULL != MyProxyConfig.lpszProxyBypass)
   {
   wcout << "AutoConfigURL is: " << MyProxyConfig.lpszProxyBypass << endl;
   GlobalFree(MyProxyConfig.lpszProxyBypass);
   }
   
   }//end else
   cout << "finished!";
   }//end main
