The best way to approach the Win32 Internet functions is to jump right into the code. The code below is sample code, with error handling removed for readability.

HINTERNET hNet = ::InternetOpen("MSDN SurfBear",
                                PRE_CONFIG_INTERNET_ACCESS,
                                NULL,
                                INTERNET_INVALID_PORT_NUMBER,
                                0) ;

HINTERNET hUrlFile = ::InternetOpenUrl(hNet,
                                "http://www.microsoft.com",
                                NULL,
                                0,
                                INTERNET_FLAG_RELOAD,
                                0) ;

char buffer[10*1024] ;
DWORD dwBytesRead = 0;
BOOL bRead = ::InternetReadFile(hUrlFile,
                                buffer,
                                sizeof(buffer),
                                &dwBytesRead);

::InternetCloseHandle(hUrlFile) ;

::InternetCloseHandle(hNet) ;

The code listing above contains four Internet functions: InternetOpen, InternetOpenUrl, InternetReadFile, and InternetCloseHandle


BOOL GetFile (HINTERNET IN hOpen, // Handle from InternetOpen()
                 CHAR *szUrl,        // Full URL
                 CHAR *szFileName)   // Local file name
   {
       DWORD dwSize;
       CHAR   szHead[] = "Accept: */*\r\n\r\n";
       VOID * szTemp[25];
       HINTERNET  hConnect;
      FILE * pFile;

       if ( !(hConnect = InternetOpenUrl ( hOpen, szUrl, szHead,
             lstrlen (szHead), INTERNET_FLAG_DONT_CACHE, 0)))
       {
         cerr << "Error !" << endl;
           return 0;
       }

       if  ( !(pFile = fopen (szFileName, "wb" ) ) )
      {
           cerr << "Error !" << endl;
          return FALSE;
      }
       do
       {
          // Keep coping in 25 bytes chunks, while file has any data left.
          // Note: bigger buffer will greatly improve performance.
          if (!InternetReadFile (hConnect, szTemp, 50,  &dwSize) )
          {
              fclose (pFile);
             cerr << "Error !" << endl;
            return FALSE;
          }
          if (!dwSize)
              break;  // Condition of dwSize=0 indicate EOF. Stop.
          else
             fwrite(szTemp, sizeof (char), dwSize , pFile);
       }   // do
      while (TRUE);
      fflush (pFile);
      fclose (pFile);
      return TRUE;
   }

Good Luck
