The script is uninterruptible as a result of Critical or Thread 'Interrupt/Priority'.

However, any other timers will continue to run by interrupting the thread that interrupted the first timer. If this happens and the interrupting thread takes a long time to finish, the interrupted timer will be effectively disabled for the duration.

The timer has been interrupted by another thread, namely another timed function, hotkey subroutine, or custom menu item (this can be avoided via Critical).

There are too many other competing timers.

The timer's function is still running when the timer period expires again.

Other applications are putting a heavy load on the CPU.

Reliability: A timer might not be able to run at the expected time under the following conditions: A shorter delay may be achieved via Loop+Sleep as demonstrated at DllCall+timeBeginPeriod+Sleep.

Timer precision: Due to the granularity of the OS's time-keeping system, Period is typically rounded up to the nearest multiple of 10 or 15.6 milliseconds (depending on the type of hardware and drivers installed). Reset: If SetTimer is used on an existing timer, the timer is reset (unless Priority is specified and Period is omitted) in other words, the entirety of its period must elapse before its function will be called again. If you wish the timer's first execution to be immediate, call the timer's function directly (however, this will not start a new thread like the timer itself does so settings such as SendMode will not start off at their defaults). Whenever a timer is created or updated with a new period, its function will not be called right away its time period must expire first. Instead, timed functions are treated just like other threads: they can interrupt or be interrupted by another thread, such as a hotkey subroutine.

Examples of their many uses include taking some action when the user becomes idle (as reflected by A_TimeIdle) or closing unwanted windows the moment they appear.Īlthough timers may give the illusion that the script is performing more than one task simultaneously, this is not the case. Timers are useful because they run asynchronously, meaning that they will run at the specified frequency (interval) even when the script is waiting for a window, displaying a dialog, or busy with another task. To change the priority of an existing timer without affecting it in any other way, omit Period. This optional parameter is an integer between -21474836483647 (or an expression) to indicate this timer's thread priority. The absolute value of Period must be no larger than 4294967295 ms (49.7 days).ĭefault: If this parameter is omitted and:ġ) the timer does not exist: it will be created with a period of 250.Ģ) the timer already exists: it will be reset at its former period unless a Priority is specified.

In any case, the timer's previous Period and Priority are not retained. If a thread started by this timer is still running, the timer is deleted after the thread finishes (unless it has been reenabled) otherwise, it is deleted immediately.

If Period is 0, the timer is marked for deletion.

For example, specifying -100 would call Function 100 ms from now then delete the timer as though SetTimer Function, 0 had been used.

If Period is less than 0, the timer will run only once.

If Period is greater than 0, the timer will automatically repeat until it is explicitly disabled by the script.

It can be set to repeat automatically or run only once: The absolute value of this parameter is used as the approximate number of milliseconds that must pass before the timer is executed. This parameter must be either given a non-empty value or completely omitted. Note: Passing an empty variable or an expression which results in an empty value is considered an error.

WORK TIMER AUTOHOTKEY UPDATE

For example, SetTimer, 0 can be used inside a timer function to mark the timer for deletion, while SetTimer, 1000 would update the current timer's Period. If Function is omitted, SetTimer will operate on the timer which launched the current thread, if any.

This occurs automatically for run-once timers, but can also be done by calling SetTimer with a Period of 0. SetTimer Function, Period, Priority Parameters FunctionĪ reference to the function object is kept in the script's list of timers, and is not released unless the timer is deleted.
