Control character of a bar code found in a BarCodes variable Hide the details
<Result> = BCCalculateControlCharacter(<Bar code>)
<Result>: Character string Control characters in the bar code.For more details on the error, use ErrorInfo. <Bar code>: BarCode variable Name of the BarCode variable containing the description of the bar code to analyze.
Control character of a specific bar code Hide the details
<Result> = BCCalculateControlCharacter(<Bar code type> , <Value of bar code> , <Extended code>)
<Result>: Character string Control characters in the bar code.For more details on the error, use ErrorInfo. <Bar code type>: Integer Type of bar code to analyze (the different types of bar codes supported by WINDEV are presented in Managing bar codes). | | | | BC_CODABAR | Codabar bar code. | Bar code that can be used with <Extended code> corresponding to BC_Check. | | BC_CODE11 | Code11 bar code. | | | BC_CODE39 | Code39 bar code. | Bar code that can be used with <Extended code> corresponding to BC_Extended or BC_Check
The value of the bar code can contain the start and end characters ("*" character). In this case, these characters will be added to the drawing of the bar code and will be printed in the text displayed below the bar code.
If these characters are not found in the value of bar code, they will be automatically added to the drawing of bar code.
However, they will not be printed in the text displayed below the bar code. | | BC_CODE93 | Code93 bar code. | Bar code that can be used with <Extended code> corresponding to BC_Extended or BC_Check). | | BC_CODE128 | Code128 bar code. | | | BC_EAN8 | EAN-8 bar code. | Possible values for the bar code:- 7 characters,
- 7 characters + 2 additional characters ("0123456+22" for example)

If this option is selected, the BC_ControlDigits and BC_Charsets constants are automatically taken into account. | | BC_ControlDigits | Bar codes containing control characters (valid for the BC_CODE128 and BC_EAN128 bar codes only). By default, control characters are enclosed between "<" and ">". To avoid interpreting these characters as control characters, simply double the first "<": - "<C40>" = control character,
