why timer not fired in console application?

TheMSsForum.com: The Microsoft Software Forum

Hi, all,

I created one timer in one console application, and this timer associated
with one timer-function. This console application also printed some string
at console screen.

Now the problem is that the timer funcion never fired though the timer was
really created successfully because the timer ID was valid. But if I
created one separate thread and created the timer within this thread, then
all things OK.

Why? We shouldn't create timer in console thread that interacts with user?
Any one could answer me? Thanks.

For Windows timers (SetTimer) to work, you need a message loop. See the
documentation.

Windows calls timer callbacks while in GetMessage call. See timers in the
SDK documentation.
