How SendKeepActive does really work ?

[Rickname]

Hi,

Im wondering how the function "SendKeepActive" does really work - and I mean not how to use the function, but instead what's the C/C++ code behind this function ?

I'm asking because I want to create a very fast program that keeps a specific window active whenever looses focus, and activate it back. Tried a While loop with WinActivate but is not even close as fast as SendKeepActive . So how can SendKeepActive keep a window focused that fast ? ?

It saves the Handle of the window you want to SendKeepActive and performs an SetForegroundWindow() before each Send after checking whether or not it still exists.
