Well, yes it does get the property from global::Properties.Settings.Default.MyConnection, however, the property is read-only. I do see some other functionality there, such as a Propteries and PropertyValues collection that are a member of this item. So, maybe
you can change it through some other method. But, in the 5 minutes I have had to look at it, I did not find it.
I will be looking at the Transaction piece tomorrow.
