How to add a barcode to a Visual Studio project


You can use the ActiveBarcode control in Visual Studio like you do with any other control, e.g. a button. First you have to add the ActiveBarcode control into the development environment.

1. Adding ActiveBarcode to the development environment

Go to the menu "Tools" and select the function "Choose Toolbox items":

Barcode, Visual Studio


A dialog appears. As ActiveBarcode is a COM component first select the tab "COM Components". A list of the available controls will be displayed. Select "ActiveBarcode" and activate it.

Barcode, Visual Studio


Then click OK. Now ActiveBarcode is added to your development environment.

2. Use ActiveBarcode in your project


Create a new project. Be aware that you select a project type that supports ActiveX controls:

Barcode, Visual Studio


To add the ActiveBarcode Control to a form you select the function "Toolbox" from the "View" menu first. This opens the toolbox. "Toolbox". Have a look or search for the ActiveBarcode Control in the toolbox now.

Barcode, Visual Studio


Click on ActiveBarcode there and move it the form you want to place the control. The control will then be placed on this form.

Barcode, Visual Studio


You can change the barcode properties of the barcode control now or later. In this example we change the background color to white:

Barcode, Visual Studio


Now add a "Textbox" to this form, too.

Barcode, Visual Studio


Double click this textbox now to open the source code for the event "Textchange". We will use this event to change the barcodes content every time the textbox changes.

Barcode, Visual Studio


This code example is for Visual Basic. With Visual C# you use the following code for the assignment og the text property:

axBarcode1.Text = textBox1.Text;
That's it. Now launch this example application:

Barcode, Visual Studio


If you change the content of the textbox in the running application, the barcode will encode this.

Optional: Non visual usage of ActiveBarcode

You also can create ActiveBarcode at run time and use the the control:

In the following example ActiveBarcode is created invisible, then a Code 128 with the encoded content "Example" is generated and saved as image file by using the SaveAsBySize function.

Visual Basic:
Dim MyObject As Object
MyObject = CreateObject("ACTIVEBARCODE.BarcodeCtrl.1")
MyObject.text = "Example"
MyObject.typename = "Code 128"
MyObject.SaveAsBySize("example.bmp", 400, 100)
Visual C#:
BARCODELib.Barcode ab = new ACTIVEBARCODELib.Barcode();
ab.Text = "123456789012";
ab.TypeName = "EAN 13";
ab.SaveAsBySize("example.bmp", 400, 150);
