Same way as you would do this in your application when you don't know in
advance which elements are visible.
Take a look at Platform SDK and messaging (SendMessage) for controls.
Of course you will need a lot of plumbing - find out another application,
its window(s), controls in windows etc.
It's not that complex but also not that simple - especially in general case.
