Hello, @lemfaki Thanks for your feedback! About your issue, apparently, your data source does not support TWAIN2 mode, although it reports this. Try check it out using TWAIN1.x.
It seems so yes.. Do you have any TWAIN1 samples i can try out?
See Use TWAIN 2.x wiki page, Saraff.Twain.NET CS Samples and Saraff.Twain.NET Outproc Samples
Btw i tried this just to test this out.TWAIN 2.5 Specification from https://twain.org/specification/ This seems to work with the scanner i am having the problem.. Maybe i am not doing something right? I already used the [Saraff.Twain.NET CS Samples] as a tempalte for my program.
With the [Saraff.Twain.NET Outproc Samples] i can see that Twain 1.x can read the values of the scanner while 2.x indeed recieves the same error as me..
Sorry for the spamm.. I found the problem.. Didn't have the latest TWAINDSM.dll files.. After i updated them, it worked like a charm
Hello there.. I have created an app which works like a charm with your amazing library.. I tried using a second scanner for feedback but i am getting this error .
TwainException Unrecognized MSG DG DAT combination. at Saraff.Twain.Twain32._RegisterCallback() at Saraff.Twain.Twain32.OpenDataSource()
Scanner i am using is Epson DS-410. Before calling OpenDataSource() i am checking twain321.IsTwain2Supported twain321.IsTwain2Enable
both return true
Thank you in advance.. i really love your work
