AdlibRegister time intervall too short

Recommended Posts


I have an Adlib function "runAdlib" which normally takes 0.1 seconds.

The function is registered to run every 2 seconds.

Under certain circumstances the Adlib function has to do some more work, running between 0.5 and perhaps 3 seconds.

To prevent the function to be run while active, I do a


as 1st statement in the function.

The function is registered before exit of the function:

AdlibRegister("runAdlib", 2000)

See also attached sample program "AT1.au3".

However, it appears that the duration of the function runAdlib is accumulated to the interval time between I want the function to be run.

This ends up in an interval way below 2 seconds if the adlib function takes more time.

The system is WinXP/SP3 and AutoIt-

What am I doing wrong?

Do I misunderstand the AdlibRegister call?

Attached is a sample code (AT1.au3) to describe the issue.

The logfile AT1.log, produced by AT1.au3, shows the following:

17:04:45.078 runAdlib-in after=21892.276251

17:04:47.203 runAdlib-out elapsed=2.152

17:04:49.234 runAdlib-in after=2.007809 <--- ok, 2 seconds

17:04:51.375 runAdlib-out elapsed=2.159

17:04:51.406 runAdlib-in after=0.020625 <--- too soon

17:04:53.515 runAdlib-out elapsed=2.130

17:04:53.562 runAdlib-in after=0.020682 <--- too soon

17:04:55.671 runAdlib-out elapsed=2.123


Thanks for hints and enlightment :-)

Another approach is to leave the adlib registered rather than unregister it, but use a global variable like this.

Global $Busy = false

   if $busy then return

   $Busy = true


   $Busy = false
