Code 128 Barcodes in Crystal Reports

• This tutorial shows how to add Code 128 B barcodes to your Crystal Reports.
• See the video or simply follow the steps below.

Step 1. Add a new formula

• In the Field Explorer, right click Formula Fields and click New...

• Enter a name for the new formula.

Step 2. Locate the Code 128 Functions

• The functions may be listed under one of these two locations:
  Functions > Additional Functions > Visual Basic UFLs (u2lcom.dll)
  Functions > Additional Functions > COM and .NET UFLs (u212com.dll)
• See here for function descriptions

Step 3a. (For Text Fields): Enter the function name in Formula Editor

• If your data field is text (string), enter the function as below:
• Code128B({Items.item_barcode})
• Items.item_barcode is the name of the table and field from your data source.
• Click on Save and close. Continue to Step 4.

Step 3b. (For Numeric Fields): Enter the function name in Formula Editor

• If your data field is numeric, it must be converted to text. This is done using the Crystal Function ToText(), as below:
• Code128B (ToText({Items.item_price}, 0, ''))
• Items.item_barcode is the name of the table and field from your data source.
• Click on Save and close.

Step 4. Add a barcode to the report

• Drag the formula from Field Explorer to the report

• Change the font properties to:
  Font Name: BCW_Code128B_2
  Font Size: 24

The report is now ready

• Click on Preview to see or print it.

Code128Auto()

• Code128Auto() Encodes data in the most efficient way possible, using a combination of subsets if necessary. Supports all 128 ASCII characters.
• This function should be used with one of the following fonts:
  BCW_Code128_1 through BCW_Code128_6 (does not show human readable text)
• This function requires the use of a barcode font without human readable text. However, the text can easily be displayed in a separate formula field with a font such as Arial.
• To encode a control character, enter it in the format: ^000, where 000 is its digital ASCII value. For example, ABC^009 encodes ABC followed by TAB. To encode FNC1, enter: ^F1

Code128A()

• Code128A() Encodes data using Code 128 Subset A only. It supports numbers, upper case letters, control characters (such as tab or new-line), space, and the following: !"#$%&'()*+,-./:;<=>?@[\]^_
• This function should be used with one of the following fonts:
  BCW_Code128A_1 through BCW_Code128A_6 (shows human-readable text under barcode)
  BCW_Code128_1 through BCW_Code128_6 (does not show human readable text)
• To encode a control character, enter it in the format: ^000, where 000 is its digital ASCII value. For example, ABC^009 encodes ABC followed by TAB. To encode FNC1, enter: ^F1

Code128B()

• Code128B() Encodes data using Code 128 Subset B only. It supports numbers, upper and lower-case letters, space, and the following characters: !"#$%&'()*+,-./:;<=>?@[\]^_`{|}~
• This function should be used with one of the following fonts:
  BCW_Code128B_1 through BCW_Code128B_6 (shows human-readable text under barcode)
  BCW_Code128_1 through BCW_Code128_6 (does not show human readable text)
• It is possible to encode control characters using the function Code128B() by temporarily shifting to Subset A. This process is automatic.
• To encode a control character, enter it in the format: ^000, where 000 is its digital ASCII value. For example, ABC^009 encodes ABC followed by TAB. To encode FNC1, enter: ^F1

Code128C()

• Code128C() Encodes data using Code 128 Subset C. It supports numbers only and must contain an even number of digits.
• The digits are encoded in pairs of two, resulting in a barcode about half as wide as subset A or B.
• This function should be used with one of the following fonts:
  BCW_Code128C_1 through BCW_Code128C_6 (shows human-readable text under barcode)
  BCW_Code128_1 through BCW_Code128_6 (does not show human readable text)
• To encode FNC1, enter: ^F1
