Font Encoder & Check Digit Calculator
(Visual Basic and Visual FoxPro Source Code Included)

IDAutomation's Font Encoder & Check Digit Calculator with Visual Basic source code works with IDAutomation's barcode fonts to create a string that, when combined with IDAutomation's barcode fonts, will create a correct barcode. The string used to create the barcode may also be copied to the clipboard, making it easy to paste bar codes into other Windows applications.

The following links will assist with implementation:

NOTE: The Font Encoder & Check Digit Calculator is not to be used with IDAutomation's Universal Barcode Fonts; use the encoder provided with that application.

Additional Font Tools: Microsoft Office Macros | Windows Font DLLs | Crystal Reports UFL | PDF417 Encoder

The compiled application is ready to install and is designed to calculate check characters for the barcode fonts available from IDAutomation. This application is distributed as shareware and is compatible with Windows 95 and greater including Windows 98, NT 3.51, NT 4.0, Windows 2000 and Windows XP. The Visual Basic (VB) 6.0 and Visual FoxPro (VFP) source code for the application allows developers to print barcodes directly from their applications without the use of DLL or OCX files. Programmers that are coding in another programming language can also use the source code as a guide.

 Barcode Check Digit Calculator & Printing Application Tutorial:


After the application is installed, it can be accessed by an icon placed in Start - Programs. In this example, IDAutomation creates a barcode encoding the data "Code 128 Test" in a Microsoft Word document. NOTE: Code 128 fonts MUST be used for version 2.0 and above for the Code 128 and UCC128 functions.
  1. After the application starts up, enter "Code 128 Test" in the "data to encode in barcode" field. Example, choose the "Copy to Clipboard" option and press the "Code 128 Set B" button.
  2. In the MS Word application, place the cursor on the area for the barcode and choose the IDAutomationC128M font.
    NOTE: When selecting the font from the pull down menu, please do not use the fonts that begin with the "@" Symbol. Instead, scroll down in the list and select the ones that begin with "IDAutomation".
    Paste bar codes into your Windows applications
  3. Choose Edit - Paste to place the barcode into the application.
    This is a Code 128 barcode pasted into MS Word.

This application can be used to print barcodes on other operating systems such as Macintosh. As an example, to place a UPC-A barcode in a Macintosh document: Start the Barcode Check Digit Calculator & Printing Application on a Windows PC. Enter the UPC-A number to encode in a barcode (in this case let's say it is "20348934382"). Then choose the UPC-A button. The "string to print the barcode" will display the characters to be typed on the Macintosh to create the barcode, in this case it displays "W(c03489*NONSMm(W". On the Macintosh application, select the font "IDAutomationUPCEANL" and then type the characters of the string into the document.

 Conversion to Other Languages:

To sign up for monthly updates about new products or upgrades, please click here.It is IDAutomation's intention to write IDAutomation's Visual Basic source code using as few functions as possible to allow for easy conversion to other programming languages. If a source code is created in another language and is designed to be shared with others, please contact IDAutomation. In some cases, discounts can be provided for IDAutomation products if a working source code is provided that would be beneficial to others. All of the barcode functions reside in the IDAutomationVBA.bas module of the Visual Basic application. The following table is a list of common Visual Basic functions used in IDAutomation's source code and what the codes do:

VB Function What it does
Asc(character) Converts a character to the ASCII value
Chr(n) Returns the character represented by the number n in ASCII
Len(string) Returns the length of a string
Mid(string, x, n) Returns n number characters from a string starting from location x
(number Mod n) Returns the remainder after number is divided by n
Right$(string, n) Returns n characters starting from the right of the string
RTrim(LTrim(string)) Removes spaces before and after a string
