I'm working on a web browser and I need to know how to store history & bookmarks permanently as currently after the browser is closed all data is lossed.

Should I put it on a DB? Suggestions?

PS: They are currently being saved on a ListBox.

a database would probly be overkill for this, i believe most browsers just use text files or at most an xml to store favorites.

You can add/delete from it like any other list. Set it as the Listbox's DataSource.
ListBox1.DataSource = My.Settings.History

Just make sure that user settings is set to automatically save or do it in your code in the form closed event handler.

 Private Sub Form1_FormClosed(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosedEventArgs) Handles Me.FormClosed
   My.Settings.Save()
End Sub

Private Sub Form1_FormClosed(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosedEventArgs) Handles Me.FormClosed
My.Settings.Save()
End Sub

Well there were no syntax errors. Just when I published the project, I went to Google and I closed the program. I reopened it and found no records of me going to Google and I've done as @TnTinMN told me. :(

Hi,
Where do you actually write the entry to your setting? Are you saving the updated setting?

Yes in the main form just before it closes.

Here is a very crude webbrowser example that maintains two history listes. It may give you some ideas. This example uses datatables instead of a string collection.
