检查计时器是否已经启动

Question

How do I know if the timer is running or already started? Without waiting the time is elapsed?

UINT_PTR nID = SetTimer(123, 60x1000, NULL);  // Info after 1 Min.
bool bTimerStarted = false;     // do I need this bool var to check the state of the timer? 
if (nID == 123)
   bTimerStarted = true;

  

Answer 1

You cannot. There is no API to query whether any given timer exists, without also resetting that timer (which SetTimer can do).

Then again, I cannot think of a situation where this would be required. Unless you've designed yourself into a corner previously. In that case, solve the architectural issue, and you'll find that you won't need this information either.
