Christobal,

I got the error unresolved external

    HB_FUNC( DOWNLOADFILE )

            HRESULT hr;

            hr = URLDownloadToFile( NULL, hb_parc( 1 ), hb_parc( 2 ), 0, NULL ) ;

   local cFile := "C:\Work\Errori\download\storico_.zip"
   local cUrl  := "https://www.lottomatica.it/STORICO_ESTRAZIONI_LOTTO/storico.zip"

    DELETEURLCACHEENTRY( cUrl )

    URLDOWNLOADTOFILE( 0, cUrl, cFile )
 
RETURN NIL

DLL STATIC FUNCTION DELETEURLCACHEENTRY( cUrl AS LPSTR ) AS BOOL;
    PASCAL FROM "DeleteUrlCacheEntryA" LIB "wininet.dll"

DLL FUNCTION URLDOWNLOADTOFILE( pCaller AS LONG, cUrl AS LPSTR, cFileName AS LPSTR, nReserved AS DWORD, nFnCB AS LONG ) AS LONG;
