AnyLength: Decode lengths of any number.This property can be any of the following values: Once you know that it's supported, you can set the DecodeLengthKind, which is of type BarcodeSymbologyDecodeLengthKind. Setting the specific length of the data you require can prevent invalid scans.īefore setting the decode length, check whether the barcode symbology supports multiple lengths with IsDecodeLengthSupported. Barcodes of these symbologies can be located near each other containing different data often of specific length.

Some symbologies are variable length such as Code 39 or Code 128. bool success = await claimedBarcodeScanner.SetSymbologyAttributesAsync(īarcodeSymbologies.Upca, barcodeSymbologyAttributes) This method returns a bool, which is true if the attributes were successfully set. When you've finished modifying the attributes and are ready to set them, you can call SetSymbologyAttributesAsync. BarcodeSymbologyAttributes barcodeSymbologyAttributes =Īwait claimedBarcodeScanner.GetSymbologyAttributesAsync(BarcodeSymbologies.Upca) The following code snippet gets the attributes of the Upca symbology for a ClaimedBarcodeScanner. You can get the attributes of a given symbology with GetSymbologyAttributesAsync. With the BarcodeSymbologyAttributes class, you can get and set these attributes for a given ClaimedBarcodeScanner and barcode symbology. Var symbologies = new List Īwait claimedBarcodeScanner.SetActiveSymbologiesAsync(symbologies) ĭifferent barcode symbologies can have different attributes, such as supporting multiple decode lengths, transmitting the check digit to the host as part of the raw data, and check digit validation. The following example sets the active symbologies of a claimed barcode scanner to Code39 and Code39Ex: private async void SetSymbologies(ClaimedBarcodeScanner claimedBarcodeScanner) You can call SetActiveSymbologiesAsync to enable a specific set of symbologies while those omitted from your list are disabled. This can be done after you have established aĬlaimedBarcodeScanner object using ClaimScannerAsync. Once you know the symbologies that your scanner supports, you can set the symbologies that you want it to recognize.

For example, to ensure a user scans the right barcode, you could constrain scanning to UPC or EAN when acquiring item SKUs and constrain scanning to Code 128 when acquiring serial numbers. This is particularly useful to block symbologies that you do not intend to use in your application. In some cases, you may want to use a subset of symbologies that the barcode scanner supports. The following example checks if the barcode scanner supports the Code32 symbology: bool symbologySupported = await barcodeScanner.IsSymbologySupportedAsync(BarcodeSymbologies.Code32) To determine if the scanner supports a specific symbology you can call IsSymbologySupportedAsync. String symbology = BarcodeSymbologies.GetName(item) ĭetermine if a specific symbology is supported Var supportedSymbologies = await barcodeScanner.GetSupportedSymbologiesAsync() įoreach (uint item in supportedSymbologies) The following example gets a list of the supported symbologies of the barcode scanner, and displays them in a text block: private void DisplaySupportedSymbologies(BarcodeScanner barcodeScanner, TextBlock textBlock) Once you have a BarcodeScanner object by using BarcodeScanner.FromIdAsync, call GetSupportedSymbologiesAsync to obtain a list of symbologies supported by the device. This can be useful if your application requires a specific symbology that may not be supported by all scanners or you need to enable symbologies that have been either manually or programmatically disabled on the scanner. Since your application may be used with different barcode scanner models from multiple manufacturers, you may want to query the scanner to determine the list of symbologies that it supports. Determine which symbologies are supported

The Universal Windows Platform barcode scanner APIs allow an application to control how the scanner processes these symbologies without manually configuring the scanner. Some common symbologies include UPC, Code 128, QR Code, and so on. A barcode symbology is the mapping of data to a specific barcode format.
