yeah, it was AccessViolationException.
ptr not null (0 or some value).
for example, in case of TW_CAMERA it was not in a first pass – it read about 4 characters (but nonsense characters). I have tryied document with no barcode, with one barcode and also one with 48 barcodes…odd,.. that method only traces out info when the driver reports rc_success, but ok – I’ll add the catch block to the next release. lemme know if you see anything else strange.
Do you have any twain apps that report the correct barcode information on that device?

Hi, Zelvak.
Have you ever worked it out? I wonder whether it is the latest version of the Barcode Scanner? I am also looking for a fine barcode scanner whose way of processing is simple and fast to help me scan aztec barcode. It will be better if it offers free trials for users to check. Any suggestion will be appreciated. Thanks in advance.Best regards,
Peter
