There is no such concept as default, in that sense. More exactly, the default is empty string, but you are talking about something else; and this is nothing but just setting some text to the label, just the opposite, not default, but new text. You are talking about showing different text after you start the same application again. It means that you need to
persist the text. In other words, write the current states to some file and read it when the application started. Where to write it and read from? Your application should behave nicely and not contaminate the OS with its data file and, at the same time, not face access violation. So, you can use so called "special folder".
