    It would be nice to have the ability to decode bar codes by supplying an image from a source such as the user's webcam. I don't see anything like that in the barcode reader control since the control handles picking the image etc. as a closed solution. Do you have any plans to provide something like this?

    Hi Earnest,

    Indeed, we already have this on our radar. We plan to ship such component with the next release of RadControls -- Q2 2013.

    Kind regards,

    Hi Pradeep,

    RadBarcodeReader has been added in the latest release of Barcode suite of RadControls for WPF. I guess you are using an older version of RadControls for WPF. If then, update your RadControls to the latest version. Please have a look at the following code which demonstrates the usage of RadBarCodeReader.

    XAML:
    <telerik:RadBarcodeReader OpenButtonText="Choose Image" DecodeButtonText="Decode Image"/>

    The decoded text from the image can be obtained from ResultText.

    Thanks,
    Shinu.

    Hi Shinu,
    As per my query u replied like this,

    RadBarcodeReader has been added in the latest release of Barcode suite of RadControls for WPF. I guess you are using an older version of RadControls for WPF. If then, update your RadControls to the latest version. Please have a look at the following code which demonstrates the usage of RadBarCodeReader.

    The decoded text from the image can be obtained from ResultText.
     
    But, this control captures the existing QRcode image which is locally saved in the system. My requirement is, I want to read the QR code from webcam. is there any control to read the QRcode from webcam? plz let me know.

    Thanks & Regards
    Pradeep

    Hi Pradeep,

    As far as I know the latest release of Telerik RadControls suite for WPF does not have one such control to read the QR code directly from the webcam. Based on Ves reply, Telerik already have this on radar and they are planning to ship such component with the next release of RadControls -- Q2 2013.

    Thanks,
    Shinu.

    Can I get an update on this?  Has the functionality asked for in previous posts been added to the bar code reader?

    Hi Joel,

    You can use the BarcodeDecoder class. For example:
    BarcodeDecoder decoder = new BarcodeDecoder();
    decoder.ImageSource = new BitmapImage(uri);
    decoder.DecodingComplete += Decoded;
    decoder.StartDecoding();
