Generate Code 39 in .NET WinForms Using C# or VB.NET
It is simple to generate Code 39 barcode image in .NET Windows Forms using C# or VB sample code. And "KeepAutomation.Barcode.Windows.dll" should be added to your project reference beforehand.
C# Sample code
     BarCode code39 = new BarCode();
code39.Symbology = KeepAutomation.Barcode.Symbology.Code39;
code39.CodeToEncode = "123";
code39.generateBarcodeToImageFile("C://barcode- code39-csharp.gif");

code39.CodeToEncode = "Code 39"

Generate Code 39 with Check Digit in .NET WinForms
Code 39 barcode is a self-checking linear barcode. However, it may use a modulo 43 checksum digit in applications that require very high level of accuracy, such as HIBC and LOGMARS. Users may add modulo 43 check digit using "ChecksumEnabled" property and display it as the last character in Code 39 data sequence with "DisplayChecksum" property enabled.
C# Sample code
     barcode.ChecksumEnabled = true;
barcode.DisplayChecksum = true;
VB Sample code
     barcode.ChecksumEnabled = true
barcode.DisplayChecksum = true
Generate Code 39 with Start and Stop Character in WinForms
Unlike other linear barcode, Code 39 may add a human-readable symbol "*" as the start and stop character. However, symbol "*" is not a part of encoded data and cannot be transmitted by the decoder. Users may display it in Code 39 barcode with "DisplayStartStop" property enabled.
C# Sample code
     barcode.DisplayStartStop = true;
VB Sample code
     barcode.DisplayStartStop = true
Generate Code 39 with I & N Value Customization in WinForms
"I", intercharacter gap, is a special value for Code 39 that stands for the space between each two character. The default value is 1, users may adjust it with "I" property. "N" value means the wide to narrow bar ratio, users are able to modify it by setting the "WideNarrowRatio" property. The default value is 2.
C# Sample code
     barcode.I = 1.0f;
barcode.WideNarrowRatio = 2.0f;
VB Sample code
     barcode.I = 1.0f
barcode.WideNarrowRatio = 2.0f
