Run my Application Only Once

To run your application only once (i.e. the first time the user inserts your CD-ROM, and no other time), place the following code in the On Startup event of your project:

--retrieve value from the registry. If the key does not exist, result = ""

result = Application.LoadValue("Application_Name", "First_Time");

 

--if there was no key, the program has never been run

if result == "" then

   Application.SaveValue("Application_Name", "First_Time", "yes");

   Dialog.Message("title", "this is the first time this program has run");

else

   Application.Exit();

end

Tip: You can also use Window.Close(Application.GetWndHandle(), CLOSEWND_TERMINATE) in place of Application.Exit().  This will close the window before the window draws itself (i.e. the user will see nothing).
