background application, action to do on PC shutdown (and suspend?)

[Torsten Mohr]

Hi,

i'd like to write an application that stays in the background
and has an icon in the taskbar to access it.  This part works
fine.

That application should also do some small tasks when the PC
is shut down.  I wonder now what callback i could use for that.

wxApp::OnExit() did not seem to work, i did not find any other.

The application does not need to be portable, it would be ok
if it would work only on Windows.

It would also be great if i could do some actions on other
events like: Suspend to Disk, Suspend to RAM, Low Battery, ...

It would be great if anybody could give me some hints here.


Best regards,
Torsten.
