This event occurs after a successful scan event.

The scanned data is variable length and consists of the PosBarcodeScannerDataReceivedEventData structure followed by ScanDataLength bytes of raw scan data followed by ScanDataLabelLength bytes of decoded scan data in which the header and footer information is removed, leaving only the scanner data. The data buffer for this event is as follows.

Syntax

typedef struct _PosBarcodeScannerDataReceivedEventData
{
    PosEventDataHeader Header;
