GetSupportedDecoders

Description

Retrieves the list of supported decoders.

Applies to

BarcodeScanner objects

Syntax

Integer scanner.GetSupportedDecoders ( intDecoders [ ] )

Argument	Description
scanner	The scanner object that is associated with the scanner for which you want to obtain a list of enabled decoders
intDecoders [ ]	Array of integers that correspond to the decoder IDs of the supported decoders

Returns

Integer. Returns 1 for success or one of the following negative values if an error occurs:

-1 Unspecified error
-2 Supporting DLL not loaded error
-3 Initialization error other than DLL not loaded
-4 Error in the passed in arguments
-5 Something in the object instance is inconsistent
-6 Call to the driver failed
-7 Error opening the specific scan device
-8 Error in the internal buffer allocation
-9 Incorrect scan state for the requested action (typically benign)
-10 Low level device error
-100 Feature not implemented

Usage

The supported decoders are defined by the firmware of the scanner device. The subset of decoders to use for a scanning operation can be obtained by a GetEnabledDecoders function call.

Examples

Example 1

The following example places the IDs of supported decoders in an array:

integer li_rtn, li_firstID, li_secondID, l_IDs[ ]

li_rtn = l_scanner.GetSupportedDecoders(l_IDs)

li_firstID = l_IDs[1]

li_secondID = l_IDs[2]
