Itp.WpfScanners 2.0.9

ITP WPF Barcode Scanner API

Keyboard-like incorporation of barcode scanners into WPF applications. Support for Serial and HID barcode scanners.

ScannerScopes are a container element which handles scans which occur when focus is within the scope.

Scanner scopes connect to a parent ScannerControlScope, which "owns" the scanner and interacts with hardware.

When focus is outside of any ScannerScopes, the scanner is disabled or ceded to other applications

            <TextBox Text="This side of the form is not scanner enabled" />
            <GroupBox Header="This side is enabled" Grid.Column="1">

                            <cscan:ScannerScope x:Name="scope2" ScanReceived="scope2_ScanReceived">
                                <StackPanel Orientation="Vertical">
                                    <Button Content="this is on the inside" x:Name="btS2" />
