PDF 417 Barcodes in MS Access Query

Encode PDF 417 Barcodes in Access Query

  • This tutorial shows how to encode the barcode value directly in a SQL query.
  • The query is based on a data table. It has all the same fields as the table, plus one barcode field.
  • The benefit of this method is the query can be used as data source to an Access Report, Form, or even other programs like MS Word or Publisher.
  • Any software which imports from an Access database can create PDF 417 barcodes.
  • Watch the video or follow the steps below.

Step 1. Import module with barcode functions

  • Click on Database Tools tab > Visual Basic (or press Alt + F11).
  • Right-click the database and Import File....
  • Select BarCodeWizPdf417.bas.
  • The default location of the file is:
    Program Files\BarCodeWiz\BarCodeWiz PDF 417 Fonts\BarCodeWizPdf417.bas
  • The following module should now be part of the Access file.
  • Create a new table or use an existing table. Our table has the following data:
  • item_sku is a Text field containing the barcode data we will encode.
  • item_name is a Text field with item description
  • item_price is a Number field with the item's price

Step 3. Create a new Query

  • Click on Create tab > Query Design

Step 4. Add our table to the query

  • Click on Query Design and select Add Tables
  • Double-click on Items in the Add Table dialog, and click Close.

Step 5. Edit Query

  • Add all items in the first column: Items.*
  • Add a new calculated field to show the encoded barcode:
    MyBarcode: Pdf417Encode([item_sku])

Step 6. Save the Query and preview

  • The field MyBarcode contains the encoded value of item_barcode. The function Pdf417Encode() encodes the text into the PDF 417 barcode.
  • This query may be used anywhere you'd normally use the Items table.
  • Change the Font Name and Size in the Report to display it as a barcode.

EXAMPLE: Using the query as a data source for a Report

  • Create a new report: Create > Report Wizard
  • Select the ItemsQuery as the source and select all fields.
  • Click Finish and edit the report in Design Mode.
  • Switch your report to Design View, by right-clicking it and selecting "Design View".
  • Edit the text box  (right-click on the text box and select: "Properties") to change the Font Name and Size:
    Font Name: BCW_PDF417
    Font Size: 4
  •  Set "Can grow" to Yes.
  • It may be necessary to make the column with the barcode a bit wider.

NOTE:  For smaller barcodes, you can set the point size as low as 2pt

  • You can now Print Preview the report.
