The 15 minute WWW browser
No attachments for this post
It took Netscape months to create their first browser, and Microsoft wasnt able to follow up that trick until years later. But you can create a world wide web browser in less than 15 minutes, even if you are a Visual Basic novice! The following tutorial will show you how to create an Internet browser using the Microsoft Internet Control (part of Internet Explorer). My only caveat is that if you end up putting the big-boys out of the Internet business with your creation, that you give me a litle credit in your About box! ;)

If you are running Visual Basic 5.0 or 6.0 the Microsoft Internet Controls are included with VB, so you don't need to do anything special to get them. If you are running an older version, you may still be able to get the controls for free from Microsoft's site at www.microsoft.com.
1)Create a new Visual Basic project.
2)Add the Microsoft Internet Controls to your project. In
VB6 you add new custom controls to a project by going to
the Project menu and choosing the Components sub-menu, and
choosing the control you want to add. In other versions of
VB, consult your help on adding custom controls. The name
of the custom control is: Microsoft Internet Control. This
will add two icons to your toolbox. Place the one that
looks like a globe (the Web Browser control) on your form
by double-clicking it. This control will display the web
page, so make sure you size it so that it looks presentable.
3)Next, place a text box on the upper portion of the form--
above the WebBrowser Control. This will be your browser's
address bar. To complete the address bar, place a button
next to it. Change the Caption property of the button to:&Go
4)Now add the following code to your form:
Private Sub Command1_Click()
That is it! Run your project and type www.microsoft.com
into the text box and press the GO button. (Dont forget to
start your Internet connection if its not already up). The
page will load and display just like a browser!
Now that you have an idea of how simple the control is to
use, you can take a little more time to create some more
sophisticated functionality for your browser:
1)Since the world wide wait can be taxing on your browser
users, you can create a status bar at the bottom of your
form that lets them know how much of their page has loaded.
You can use the following web browser events (see the
Microsoft Internet Controls help file, if you need examples)
2)Create a menu system on your form--just like IE and
Netscape. See the VB help if youve never done this before.
You'll want to at least create &File and &Exit.
3)Create a combobox instead of a text box that remembers
4)Let your imagination run wild!
5) For more features, check out the other browser
submissions to this site. An outstanding example is:

Here are some helpful button commands...
An answer to the questions about the favorites and the bookmarks:
1) Make a
2) Make a commandbutton cmdFav
3) Make a listbox
The code for cmdAdd:
Private Sub cmdAdd_Click()
Open "favs.txt" For Append As FN
Print #FN, txtUrl.Text &
The code for cmdFav:
On Error Resume Next
FN = FreeFile
"favs.txt" For Input As FN
lstFavs.Visible = True
Line Input #FN, NextLine$
The code for lstFavs:
txtUrl.Text = lstFavs.List(lstFavs.ListIndex)
lstFavs.Visible = False
Private Sub printmenu_Click()
Dim eQuery As OLECMDF
Error Resume Next
eQuery = WebBrowser1.QueryStatusWB(OLECMDID_PRINT)
If Err.Number = 0 Then
If eQuery And OLECMDF_ENABLED Then
WebBrowser1.ExecWB OLECMDID_PRINT, OLECMDEXECOPT_PROMPTUSER, "", ""
MsgBox "The Print command is currently disabled."
MsgBox "Print command Error: " & Err.Description
To open up new window:
Sub WebBrowser1_NewWindow2(ppDisp As Object, Cancel As Boolean)
Dim frmWB As Form1
Set frmWB = New Form1
ppDisp = frmWB.WebBrowser1.Object
frmWB.Visible = True
Set frmWB =
If you want to cancel the new window, Cancel = True.
For a proper progressbar:
Private Sub WebBrowser1_ProgressChange(ByVal
Progress As Long, ByVal ProgressMax As Long)
On Error Resume Next
ProgressBar1.Max = ProgressMax
ProgressBar1.Value = Progress
To show the percentage:
Progress * 100 / ProgressMax

You can easily view the source of the webpage you're
viewing by using 2
controls: A RichTextBox control,
and the microsoft internet transfer
If your internet transfer control is Inet1, and your
RichTextBox1, then use the following code
download and view a page's
RichTextBox1.Text = Inet1.OpenURL(" address ")
The address must be
the valid URL of an .htm or .html
