When you install our bar code plug-in extension in to 4D, you add a comprehensive range of powerful new bar code functions to 4th Dimension.
To install, simply use Windows Explorer to copy these plug-in files; CIAXCOM.4DX, CIAXCOM.RSR and ciabar32.dll to a directory named Win4DX. This directory is below the directory containing the 4D executable program file.
You must also install our bar code fonts. See: Installing TrueType bar code fonts in Windows
Step-by-step examples of use in 4D
New bar code functions;
f you are familiar with the 4D programming language, the following section describes how to access the plug-in bar code functions in your 4D program code; Methods, Triggers, Event handlers, Formulas, etc.
Note: Our plug-in contains functions that do not need a user interface, so our plug-in does not appear in the Plug-ins menu in 4D. Only plug-ins that need a user interface will appear in the Plug-ins menu.
In 4D, wherever you can select or enter 4D language statements, or 4D expressions (i.e. formula or calculation), you will now be able to view and select the new bar code functions.
For example, you can access bar code functions in; Database Methods, Form Methods and Triggers, Table Triggers, Project Methods, Event handlers, Formula editor, etc.
To view the list of functions in 4D, select the Barcode_CIAXCOM theme, or select the CIAXCOM plug-in.
Below you can see a Project Method being edited, and the following lists are being used; Table 1 CIAXCOM Commands by Themes
To add a list, right-click the title of any list and choose pop-up menu Add a list.
To change a list to the CIAXCOM list, right-click the title of any list you want to change, then choose pop-up menu Commands for the plug-in | CIAXCOM.

In the All plug-in commands list you can then expand the CIAXCOM plug-in, then expand the Barcode_CIAXCOM theme to view all available bar code functions.
