IBarCodeReaderControl::TriggerScanner

This function turns the scanner on and off. The client application must
coordinate control of the scanner with the user.
Syntax
HRESULT IBarCodeReaderControl::TriggerScanner ( BOOL
fScannerOn );
Parameters
fScannerOn [in] Set TRUE to turn the scanner on. Set FALSE to turn
the scanner off.
Return Values
HRESULT that indicates success or failure.
Remarks
The scanner will be turned on or off independent of the actions of the us-
ers. The client application must coordinate control of the scanner with the
user. When the scanner is turned on, its behavior is controlled by the trig-
ger mode. That is, in one shot mode, the laser turns off when a label is
scanned; in auto-trigger mode, the laser remains on.
