This function reads data from the bar code input device. This method per-
forms the same function as IADC::Read () except that it provides addi-
tional information about data received such as bar code symbology used,
data type, and time stamp of received data.
Syntax
HRESULT IBarCodeReaderControl::Read ( BYTE
rgbDataBuffer[],DWORD dwDataBufferSize, DWORD
pnBytesReturned,ITC_BARCODE_DATA_DETAILS
pBarCodeDataDetails, DWORD dwTimeout );
Parameters
rgbDataBuffer
dwDataBufferSize
pnBytesReturned
pBarCodeDataDetails [in]
typedef struct tagITCBarCodeDetails
{
WORD wStructSize,
ITC_BARCODE_SYMBOLOGY_ID eSymbology,
ITC_BARCODE_DATATYPE eDataType,
SYSTEMTIME stTimeStamp,
}ITC_BARCODE_DATA_DETAILS;
typedef enum tagBarCodeDataType
{
BARCODE_DATA_TYPE_UNKNOWN = 1,
BARCODE_DATA_TYPE_ASCII,
BARCODE_DATA_TYPE_UNICODE,
}ITC_BARCODE_DATATYPE;
where:
S wStructSize
Size of structure. Used for versioning structure.
S eSymbology Symbology of the returned data.
S eDataType Identifies data types as ASCII, UNICODE, etc.
S stTimeStamp Timestamp of the received data.
