ScanningManagerEvents.ScannerFound event

When the solution program calls ScanningManager.FindAndConfigureScanner, this event is fired each time a scanner is detected. The event can thus happen multiple times if the program skips the scanner.

ScanningManager.Ping() returns L_STATE_EVENTHANDLER_SCANNERFOUND

ScanEventArgs.ActiveScanner contains information about the scanner

ScanEventArgs.ActiveScanner.Port contains the port on which the scanner was found

ScanEventArgs.ActiveScanner.State contains L_SCANNER_STATE_AUTOCONFIGURED

ScanEventArgs.ActiveScanner.HardwareConfig contains info for the scanner found.

Following members are typically changed at this event to reflect solution use of hardware options:

• DisableBarcodeReader
• DisableSelectStacker
• DisableTransportPrinter
• WriteOperationsLog

The program can skip this scanner by setting ScanEventArgs.SkipPortOrScanner to true.

The program can cancel the process by setting ScanEventArgs. CancelScannerSearch to true.

Solution programs should handle this event for OpScan 2, 3 & 4/4U and iNSIGHT 2, 4 scanner models. ScanEventArgs.ActiveScanner.HardwareConfig returns false positives (TRUE) for HasSelectStacker and HasTransportPrinter. You can correct this problem as follows:

1. Ask the user to inform you of the presence or absence of these devices on the scanner, this is especially important for the select stacker
2. Update the properties DisableTransportPrinter and DisableSelectStacker within ScanEventArgs.ActiveScanner.HardwareConfig to reflect the user input
