Not exactly. When you double click on the Connected property value the
Object Inspector tries to set it to True; if LoginPrompt is True this
makes a login dialog appear. Whether you cancel the dialog or you don't
get connected for any other reason, an exception must occur, since the
desired assignment (MyConnection.Connected := True) couldn't be
performed.
This is consistent at run time too.
I hope I have made it clear enough.
