Re: Intercept messages of an app.

Note that this assumes the text being displayed is represented as a string; if it were an
owner-draw listbox it will also require reverse-engineering the ItemData field. (Example:
my "logging listbox" is an owner-draw control where each type of line is a different
subclass of the abstract log message class)

Is there a way for a separate application to log strings
sent to this listbox (and send the strings into a text file)?

What APIs should I look after.. what about spy++?

Yes, you can do it by using hooks (SetWindowsHookEx). In this case you
will have a process wide hook. Look at MSDN to see what type of hook
would be needed.
