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.
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.

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
DWORD
Value identifying the good read beep duration in ms.
Valid range for S9C: 0`2550
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.
6 — Scanner Support
ms (Default: 80).
