PostRead | The BarcodeReader has finished reading the barcode symbologies. The input parameters are: The symbologies to be read which can be obtained through the BarcodeReadSymbologyEventArgs.GetSymbologies method and the associated read options that are in the BarcodeReadSymbologyEventArgs.Options property. The resulting parameters are: The barcode data found which is in the BarcodeReadSymbologyEventArgs.Data property that may contain a valid BarcodeData object or null (Nothing in Visual Basic) when an error occurs or no barcode of this type is found. In case of an error, the exception is in the BarcodeReadSymbologyEventArgs.Error property (Refer to BarcodeReader.ErrorMode for more information). |
