Barcode ActiveX Control
OptionalCheckChar
An optional checksum character may be calculated and added to increase scanning accuracy of a barcode. This property affects Code 39, Code 39 Extended, Interleaved 2 of 5, and Standard 2 of 5. It is ignored in all others.
Note that many symbologies (such as UPC-A) require an already-calculated checksum character. Do not use OptionalCheckChar property for that purpose - it will be ignored. BarCodeWiz ActiveX will verify the supplied checksum character, and will notify you if incorrect.
Syntax
BarCodeWiz1.OptionalCheckChar [ = enum]
The settings for enum are:
| Constant | Setting | Description |
|---|---|---|
| No_Check_Char | 0 | Default setting. Barcode is encoded as entered. No checksum character is added. |
| Barcode_Only | 1 | Optional checksum character is encoded into the bar code, but not shown in text. |
| Barcode_And_Text | 2 | Optional checksum character is encoded into the bar code. It is also shown in text. |
