Reset My.Settings to values last saved - vb.net

Question

I'm currently using a "Settings" form to set various settings for my application. What I'm trying to do is to revert settings back to before any changes the user has made before opening and changing a field. I have a text box with a data binding to a setting and when I make a change and click okay it gets saved the next time I open it. When I hit cancel it also gets saved. Not quite sure if I'm approaching this correctly.
Public Class frmSettings
Private _mysettings As Configuration.SettingsBase
Private Sub frmSettings_Load(...) Handles Me.Load
_mysettings = My.Settings
End Sub
Private Sub btnCancel_Click(...) Handles btnCancel.Click
For Each p As Configuration.SettingsPropertyValue In _mysettings.PropertyValues
My.Settings(p.Name) = p.PropertyValue
Next
Me.Close()
End Sub
Private Sub btnOkay_Click(...) Handles btnOkay.Click
My.Settings.Save()
Me.Close()
End Sub
End Class

Rather than using databound control you can simply load the value of the setting when the settings form loads. It is simple doing it that way, and it works. Otherwise you would have to make a clone of My.Settings: doing _mysettings = My.Settings is only creating a pointer to My.Settings, not a copy of it.
For example, I have a Form named ChangeConnectionString which has OK/Cancel buttons and a TextBox control named connString:
Public Class ChangeConnectionString
Private Sub bnOK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles bnOK.Click
My.Settings.connectionString = connString.Text
My.Settings.Save()
Me.Close()
End Sub
Private Sub bnCancel_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles bnCancel.Click
Me.Close()
End Sub
Private Sub ChangeConnectionString_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
connString.Text = My.Settings.connectionString
End Sub
End Class
