Holy cow, I wrote a book!
A customer wanted to know if there was a way for their
application to invoke the
Aero Peek feature
so that their window appeared and all the other windows
on the system turned transparent.
No, there is no such programmatic interface exposed.
Aero Peek is a feature for the user to invoke,
not a feature for applications to invoke so they can
draw attention to themselves.
Yes, I realize you wrote a program so awesome that
all other programs pale in comparison,
and that part of your mission is to make all the other programs
literally pale in comparison to your program.
Maybe you can meet up with
that other program that is the
most awesome program in the history of the universe
and share your sorrows over a beer.
