Hi,

Language : Delphi7

Question

Q1) CAP_SERIALNUMBER = $1024;

Scanner device command to obtain the serial number?

Q2) The scanner to detect whether or not the paper instruction

Q3) ImageEnView1.IO.Acquire command when an error occurs processing the scan to.

Q4) Want to save the image as a continuous scan. Scanner Model Avision AV176 +.
Compared to other scanners scanner application process is fast but slow to think this was wondering how to solve? Other programs I've used the program compared Ez-Twain becomes. I want to respond to.

ImageEn doesn't have a method to get device serial number.

Please look at TwainParams.PaperDetectable property (and maybe others TIETwainParams paper instruction properties).

Acquire returns False on capture failure. You can know the last error with LastError and LastErrorStr properties.

Are you using TImageEnMView (instead of TImageEnView) to acquire multiple pages?
