Lesson 19 : Creating A Web Browser

Basically everyone likes to navigate the Internet using commercially produced web browsers such the Internet Explorer produced by Microsoft or those open source browsers designed by the experts such FireFox , Opera and the latest Chrome created by Google. However, isn't it cool that if you can create your very own web browser that you can customize to your own taste ? Yes, you can do that in Visual Basic 2012, and pretty easy too. In this chapter, I will show you how to create a simple web browser and get it running in a few minutes.

First of all, start a new project in Visual Basic 2012 and name it with any name you like. Here I am just using the name Web Browser. Change the name of Form1 to MyWebBrowser and the text property to Web Browser and set its size property to 640,480. Next, you need to add an engine so that your web browser can connect to the Internet, and this very engine is the WebBrowser control, located on the Toolbox on the left side, set the size property to 600,400. Next, drag a text box and place it at the top of the WebBrowser control, this will be the address bar where the user can enter the URL. Lastly, place a command button beside the text box and label it as Go and change its name to Go as well. The design interface is shown below:

The code for the web browser is surprisingly simple, it is only a single line code! Double click on the Go button and key in the following code:

Public Class Form1
Private Sub Go_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
End Sub
End Class

Now run the the program , type in any URL and click the Go button. You will be able to browse any web page you want.
