How do you write VB code that saves itself each time it runs?

I want to write an exe app that would save the changes every time it runs, without having to have any resource files or saving anything to external files. How would I go about doing that?How do you write VB code that saves itself each time it runs?
Unfortunately there is no way to save the state of the current application w/o either a) using the registry or b) saving data in the users AppData area.



You cannot modify the executable (exe) itself.
