CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).Navigate(My.Settings.homepage.ToString)

This gives me an error.

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

End sub

It says that "System.NullReferenceException was unhandled

Message="Object reference not set to an instance of an object.""

I have a value in for the setting, it is http://acedrive.tk/

<?xml version="1.0" encoding="utf-16"?>

</ArrayOfString>

What's the issue?

Please enter break mode and use Watch window to check which variable is null in this scenario. Have a look at the following link about how to use the QuickWatch Dialog Box:
