How to

Dear Friends
i wish to put my program name and directory path into the registry and later on retreive it back from the registry? how can i do this

thanks to all :)

Merry X'mas and Happy New Year for all

You don't need to save the path & title, it's always accessable via the

Code:

---

App.Path 'path to exe
App.Title 'name of exe

---

If you really want to do that, check getsetting and savesetting.

Hey! Outruner2000, here is the sample code to put the App.Path and App.Title in to the registry path:

\\HKEY_CURRENT_USER\Software\Outruner2000\Path
and
\\HKEY_CURRENT_USER\Software\Outruner2000\Title

Code:
