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 VB2010,
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 VB2010 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
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.
