Public Property Confidence As Long
The Confidence value is a diagnostic that is normally reported as:
-1 indicates that confidence not measured because it was not applicable
0 indicates failure to verify checksum or ECC. Some codes contain a checksum/ECC inherently which is always checked. For some other codes, such as Code39, there is an option to use (or not use) a checksum.
100 indicates successful recognition
1-99 indicate a value used for diagnostic purposes
