Re: How to access a scanner via TWAIN.
Posted: Tue Aug 01, 2017 11:00 PM

Estoy tratando de utilizar este dll con múltiples paginas y para escribir yo:
oScan:SetMultiTransfer(1) // Opción para escanear varias páginas
Pero está trabando el equipo cuando vacía la bandeja
Me di cuenta de que está bloqueando el equipo cuando se ejecuta: nDib := (oScan: AcquireToFile (cFilescan)).

Mi Tscan.prg está así:

METHOD AcquireToFile (cFileName) INLINE TW_ACQUIRETOFILENAME (:: hWnd, cFileName)

HB_FUNC( TW_ACQUIRETOFILENAME ) // hWnd, cFileName
{
hb_retni( TWAIN_AcquireToFilename( ( HWND ) hb_parnl( 1 ), hb_parc( 2 ) ) );
}

¿Alguien me puede ayudar?

Estoy usando FiveWin for xHarbour 13.07, Windows 7 32 bits.

Gracias amigos.

This sample is working fine here:

Code (fw): Select all Collapse

#include "Fivewin.ch"


FUNCTION MAIN()

    ? TWAIN_SCANNER( "This is a test.bmp" )

    RETURN NIL


FUNCTION TWAIN_SCANNER( cBmp )

    IF TWAIN_ISAVAILABLE() = 0
        ? "TWAIN is not installed in this computer."
        RETURN .F.
    ENDIF

    RETURN TWAIN_ACQUIRETOFILENAME( 0, cBmp ) = 0


DLL32 STATIC FUNCTION TWAIN_ACQUIRETOFILENAME( hWnd AS LONG, cFile AS LPSTR ) AS LONG;
      PASCAL FROM "TWAIN_AcquireToFilename" LIB "eztw32.dll"

DLL32 STATIC FUNCTION TWAIN_ISAVAILABLE() AS LONG;
      PASCAL FROM "TWAIN_IsAvailable" LIB "eztw32.dll"

Problem for me is, that I didn't obtain a licence at the time version 2 of this dll was available. Now they are only selling version numbers 3 and 4. This example however works only with the older dll

My function works fine with the free version of the EZTW32.DLL.

I didn't find any licence information saying that the dll itself is free. Just found, that the class tscan.prg is free. Do you have a link that clearly states the dll as free? That would be really great
