Hakan,

>Is there any example to use it?

I have never used it and it didn't come with any examples. You might try searching the forum.

Thanks James, Dutch.

Should I install any program to run this class? I have Xerox 3119 that has scanner. I can scan any document with its program.

Thanks again.

Dear Horiaon,

You must have EZTW32.DLL, FREEIMAGE.DLL. That's all.

Hi Dutch,

I have downloaded the EZTW32.dll and FreeImage.dll to my app. directory. When I start to my test application, it gives an error and application breaks and returns to os.

I try to register EZTW32.DLL using, but it gives an error when trying registering.

I use Vista, SP1. I try XP SP3. it is same error.

What can do more?
