detect if a new process has started

[sheduler]

How to detect if a new process or application has been started system wide? One way is to get then full list of processes and the just wait for changes. But it requires a timer, what I want to bypass... Maybe there are some other ways?
And the same with the active window. One way is to set Ontimer GetForeGroundWindow and just wait for it changes but again it takes much more cpu... Maybe here is an other answer too?

Hi, have a look at API Hooks. You only have to hook the CreateProcess API.

For windows use just window hooks and catch the respective message to get notified of activation.

CreateProcess hooks may be nice but are ugly, not supposed to work on Vista and not sufficient if you want to catch any process start. :stupid:
