rgbAttrBuffer Data Structures (continued)
Data Structure contained in rgbAttrBuffereAttr
ITC_RDRATTR_GOOD_READ_BEEPS_NUMBER ITC_GOOD_READ_BEEPS_NUMBER
An enumerator identifying the good read beeps number.
Valid range for S9C:
typedef enum tagGoodReadBeepsNumber
{
ITC_NUM_BEEPS_NONE = 0,
ITC_NUM_BEEPS_ONE = 1, // Default
ITC_NUM_BEEPS_TWO = 2
}ITC_GOOD_READ_BEEPS_NUMBER
ITC_RDRATTR_GOOD_READ_BEEP_DURATION DWORD
Value identifying the good read beep duration in ms.
Valid range for S9C: 0`2550 ms (Default: 80).
Note
: Value is divided by 10 for storage. On retrieval, the
scanner rounds the value to the nearest 10 ms, then multi-
plies the value by 10.
dwAttrBufferSize [in] The size of rgbAttrBuffer in bytes.
Return Values
HRESULT that indicates success or failure.
Remarks
Read ahead and non-read ahead clients can change the grid. Since
changing the grid changes the entire reader engine grid, use
IBarCodeReaderControl::QueryAttribute to retrieve the current reader
engine grid and grid changes before sending back using SetAttribute. The
grid structure is typedef struct tagBarCodeReaderGrid.
{
ITC_DI_GRID stDIGrid; // Device independent grid.
ITC_DDBARCODE_GRID stDDGrid; // Reader engine dependent grid
DWORD dwDataSourceTypeMask;
} ITC_BARCODEREADER_GRID;
ITC_DI_GRID
typedef struct tagItcBarCodeGrid
{
DWORD dwSymbologyMask; // Symbologies to be received.
} ITC_DDBARCODE_GRID;
When the scanner is enabled, it scans when the scan button is pressed or
the trigger is pulled. When the scanner is disabled, it does not respond
when the scan button is pressed or the trigger is pulled.
