I also use barcode scanner. But I never consider about the resolution problem, for the barcode reading tool can read it clearly and easily. I use this barcode scanner to read barcodes. It supports various barcode types, including rich linear barcode types and 2D barcode types, like QR Code, etc. Maybe a good barcode reader can reduce many problems.
yeah, barcode reader can be found anywhere for its convenience!

Hi, nicky. I find some sample codes for barcode recognition in VB.NET.
QR Code:Dim barcodes() As string = BarcodeScanner.Scan(“qr-code-barcode-image.gif”, BarcodeType.QRCode);
Code 39: Dim barcodes() As string = BarcodeScanner.Scan(“code-39-barcode-image.gif”, BarcodeType.Code39);thanx for sharing!i’m also interested in whether it helps!

Sorry for this late reply. As no one replied on this, I would like to share my view on this. I am not sure if Twain supports to read barcode in .net at that time. But it seems that it is ok now. If it does not support to do this, you can also try some other ways, like employing a third party control (.net barcode reader) to read the barcode in .net. You can just add the tool your program and do a few steps to finish the barcode reading. Many tools support to read many barcode types, including QR Code, PDF417, Code 39, Code 128, etc. Hope this would be helpful for others.
so old post,maybe the problem is solved,but i’d like to share another barcode tool for you,where you can find the similar barcode recognition that i do not know whether it is better than that of twain,or you can check another reader tool for data matrix
i’ve generated barcode in vb.net,but as for barcode reader for vb.net ,i just know .net barcode reader and do not know whether it can help?

Do you know that not all scanners can get information about barcodes on acquired page? Only professional scanners can get an extended image info.
Do you want to develop application for a professional scanner or for all scanners? You need use a barcode reading SDK if you want to develop application for all scanners.
Best regards, Alexander
yeah,it’s right. and i recently generated a barcode in .net , and later i also want to add the matched barcode reader ,which scan and recognize barcodes from any directions in C#, VB class and console application.
well,many people are wondering your question between barcode reader and barcode generator. ok, if sth.related, you can refer to both barcode readerand barcode generator to help yourself out…Good luck!
