Change the data type to "System.Byte[]".
Switch to "Solution Explorer" and add a new "Report" item.
Create a new "Report" item and insert a table to the report.
Add three columns in the dataset to the report table details section.
Drag and drop "Image" item to the last column and name it "Barcode".

     {
     // load data to the data table this.vProductAndDescriptionTableAdapter.Fill 
     this.vProductAndDescriptionTableAdapter.Fill(this.AdventureWorks.vProductAndDescription);
     // create a linear barcode object 
     BarCode code39 = new BarCode();
     // set barcode type 
     code39.Symbology = KeepAutomation.Barcode.Symbology.Code39;

Frequently Asked Questions

What purposes do Code 39 barcodes serve?

Code 39 barcode also known as Code 3 of 9 too, handles digits and letters and is most often used in inventory work, government agencies, the military, and electronics businesses.

How are Code 39 and Code 128 barcodes different?

Code 128 uses a mandatory checksum for data integrity, damage to it may not stop scanning. In contrast, Code 39 typically forgoes a checksum, so any damage to the barcode usually makes it unreadable.

What makes Code 39 and Code 93 barcodes different?

Code 93 is a revised version of Code 39, offering greater data capacity in a smaller symbol. This makes it a more space-efficient barcode solution.

Can lowercase letters be encoded in Code 39 barcodes?

Lowercase letters cannot be encoded in a standard Code 39 barcode, but the extended version is able to.

How small can a Code 39 barcode be?

code 39 has minimum size rules:

Narrow element width (X): The smallest bar width is set by the app's specifications.
Barcode height: At least 5.0mm, or 15% of the symbol's width (not including quiet zones) - whichever is greater.

The valid ratio of narrow to wide bars in Code 39 is from 1:2 to 1:3.
