Hmm, that won't always work. What if the user doesn't have write
permission to the application bundle, or if the application is located
on some read-only media? The write will fail in either of these cases,
and the code won't be run.
You could write it to the Application Support folder, or since it's
something you're removing anyway, you could write it to /tmp as well.

I've found in the documentation that to launch a GUI application from

From previous discussion on this list it appears that NSTask

be used to run a GUI application but how would I run and pass command
line arguments to a GUI application?
In general, you don't; Most GUI apps aren't written with receiving
command line arguments in mind. Additionally, what would you do if the
application was already running? There are other ways to pass
information to GUI applications (Distributed Objects, AppleEvents,
POSIX Pipes, Raw Sockets, Shared Memory, etc.).

Thanks for your reply, it's saved me from scanning documentation and
pile of Cocoa books for hours on end thinking that I must have missed
something.
I've got around it by creating a thread that writes a UNIX command
line for the program I want to run then use chmod() to make it
executable and then use system() to run it before using unlink() to
remove the file.
system() has an advantage in that I wanted to do a [task
waitUntilExit]; anyway and system() causes the thread to wait until
the program exits.
The program I wanted to run is called by running:
/path/tp/myapp/myapp.app/Contents/MacOS/myapp
Thanks, again for your help.
Regards, Rob.
