hi
 this is Pasted from the paqs:

I am using the eztw32.dll. It is very easy to use.
You just need this DLL in the directory of your
application. I downloaded this DLL some time ago from
the official TWAIN site www.twain.org, but I cannot find
it any longer there. Using Altavista I found another
 place:
http://www.i-rose.si/mare/programing/index.html.
 He provides also a Delphi interface. But you may also
  use mine:

function TWAIN_IsAvailable: integer; stdcall;
  external 'Eztw32.dll' index 26;

function TWAIN_SelectImageSource(Handle: hWnd): integer; stdcall;
  external 'Eztw32.dll' index 38;

function TWAIN_AcquireNative(Handle: hWnd;
  wPixTypes: integer): integer; stdcall;
  external 'Eztw32.dll' index 2;

function TWAIN_WriteNativeToFilename(Handle: THandle;
  FileName: pChar): integer; stdcall;
  external 'Eztw32.dll' index 49;

To scan an image and save it to a BMP file:

  Handle := TWAIN_AcquireNative(0, 0);
  if Handle > 0 then
  begin
    Result := TWAIN_WriteNativeToFileName(Handle, pChar(FileName)) = 0;
    GlobalFree(Handle);
  end;

Its really simple and unlike other interfaces AcquireNative only returns when the document is scanned.
