Seems great but you didt really explain what to start with. I have no idea where I put the second code. All cred due this is what I need. But its a bit vague. You have a combo box in there but what the hell is the combo box for. Its really confusing.
Darkkid, I recommend you buy a book and read up. Some times you shouldn't have to be told where to put things to know where to put them.
For example, if I told you to make a messagebox after the user clicked a button, most likely the first thing you would do is go to the Button's click event, wouldn't you?
It is amazingly simple to do this if you've migrated from a language such as VB6 where there is next to no object-orientation, wouldn't you agree? I don't code either, but I work with .Net (C#, etc) quite often, so I can make sense of your code quite thoroughly.
Edit: Sorry I forgot to comment.
Its nice and simple, and simple is the way things should be.
Dim browse As New WebBrowser
TabControl1.TabPages.Add(i, "Page " & i)
TabControl1.SelectTab(i - 1)
browse.Name = "vb"
browse.Dock = DockStyle.Fill
TabControl1.SelectedTab.Controls.Add(browse)
i = i + 1
