Hi,

I try as below to acquire images from scanner (Koda3400,sequential scans for 200 pages). It works well, also can catch the error like 'paper jam'.


If ImageEnMView1.MIO.Acquire = false then showmessage('Paper Jam');

How can I know it is completed by 'scan finished' or 'scan cancelled by user'? Since the value returned is only TRUE or FALSE, and TRUE means both of 'scan finished' and 'scan canceled by user'.

Thanks.

Hi

You would need to check whether an image has been acquired, e.g. by setting a value in OnAcquireBitmap, or comparing ImageEnMView1.ImageCount.
