Aling,
You can create timers and implement the timer proc in a console application.
But -- you must implement a message pump to get the timer messages flowing.
It may be easier to to create a message-only window, create the timer for
that window, then implement a trivial message pump. Below, please find a
quick hack that I just threw together to demonstrate the capabilities of a
timer proc in a console app. It prints "hellooooo..." 5 times, then
disappears
That said, it may be easier to start with a straight windows based program
and create a NOT_VISIBLE window - then you don't have the ugly console
window hanging about. If the console window is a required or desired
feature, then disregard the last point.
