Barcode scanner sample

This sample shows how to create a barcode scanner, claim it for exclusive use, enable it to receive data, and read a barcode. This sample uses Windows.Devices.PointOfService API.

Specifically, this sample shows how to:

  1. Create the barcode scanner

    Uses the BarcodeScanner.GetDefaultAsync to get the first available barcode scanner.

  2. Claim the barcode scanner for exclusive use

    Uses the ClaimScannerAsync to claim the device.

  3. Add event handlers

    Uses DataReceived and ReleaseDeviceRequested events.

    When an application gets a request to release its exclusive claim to the barcode scanner, it must handle the request by retaining the device; otherwise, it will lose its claim. The second scenario in this sample shows the release and retain functionality. The event handler for ReleaseDeviceRequested shows how retain the device.

The app package manifest shows how to specify the device capability name for the Point of Service (POS) devices. All POS apps are required declare DeviceCapability in the app package manifest, either by using "PointofService" as shown in this sample or by using a device specific GUID, such as "C243FFBD-3AFC-45E9-B3D3-2BA18BC7EBC5" for a barcode scanner.

The following list shows the barcode scanners that were used with this sample:

  • Honeywell 1900GSR-2
  • Honeywell 1200g-2
  • Intermec SG20

In addition to the devices listed, you can use barcode scanners from various manufacturers that adhere to the USB HID POS Scanner specification.

Note The Universal Windows app samples require Visual Studio 2015 to build and Windows 10 to execute.

To obtain information about Windows 10 development, go to the Windows Dev Center

To obtain information about Microsoft Visual Studio 2015 and the tools for developing Windows apps, go to Visual Studio 2015

Build the sample

  1. If you download the samples ZIP, be sure to unzip the entire archive, not just the folder with the sample you want to build.
  2. Start Microsoft Visual Studio 2015 and select File > Open > Project/Solution.
  3. Starting in the folder where you unzipped the samples, go to the Samples subfolder, then the subfolder for this specific sample, then the subfolder for your preferred language (C++, C#, or JavaScript). Double-click the Visual Studio 2015 Solution (.sln) file.
  4. Press Ctrl+Shift+B, or select Build > Build Solution.

Run the sample

The next steps depend on whether you just want to deploy the sample or you want to both deploy and run it.

Deploying the sample

  • Select Build > Deploy Solution.

Deploying and running the sample

  • To debug the sample and then run it, press F5 or select Debug > Start Debugging. To run the sample without debugging, press Ctrl+F5 or selectDebug > Start Without Debugging.
