Basically everyone have 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 we
can create our very own web browser that we can customize to our own taste ?
Yes, you can do that in VB2008, 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
VB2008 and name it with any name you like. Here I am just using the name
webbrowser. Change the name of Form1 to webbrowser and the text property to My
First 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.
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
Button1_Click(ByVal
sender As
System.Object,
ByVal e
As
System.EventArgs) Handles
Button1.Click
myWebBrowser.Navigate(TextBox1.Text)
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.
