Webbrowser URL

[Raoul]

Hello,
I am trying to change the webbrowser URL via the My.Settings

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        browser.Url = My.Settings.startpagina
    End Sub

With that I get:

Value of type 'String' cannot be converted to 'System.Uri'.

I tried new System.Uri() but then I had this error:

Invalid URI: The format of the URI could not be determined.

Can someone help me please??

Thanks
