How to add a barcode to a Visual Basic project
You can use ActiveBarcode in Visual Basic like any other control (e.g. like a button).
First you have to add the ActiveBarcode control into the development
1. Adding ActiveBarcode to the development environment
Go to the menu "Tools" and select the function
"Choose Toolbox items":
A dialog appears. As ActiveBarcode is a COM component first select the tab
A list of the available controls will be displayed. Select
"ActiveBarcode" and activate it. 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:
To add the ActiveBarcode Control to a form you select the function "Toolbox" from
the "View" menu first. This opens the toolbox.
Have a look for the ActiveBarcode Control in the toolbox now.
Click on ActiveBarcode there and move it the form you want to place the control.
The control will then be placed on this form.
You can change the barcode properties of the barcode control now or later.

Now add a "Textbox" to this form, too.
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.
That's it. Now launch this example application:
If you change the content of the textbox in the running application, the barcode will encode
Not 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.
Dim MyObject As Object
MyObject = CreateObject("BARCODE.BarcodeCtrl.1")
MyObject.text = "Example"
MyObject.typename = "Code 128"
MyObject.SaveAsBySize("example.bmp", 400, 100)
