adlibenable("Function",1000): How exactly does it work?

[rudi]

Hi.

I wrote a small script, that has to copy a drive ALMOST up to it's rim.

For doing so, I use the "\i386\" folder of the current windows installation's "sourcepath" from registry. (I always copy over the Win-Setup source files to HDD for any installation I'm doing...)

With "Adlibenable("WipeOld",1000)" I wanted to check, if the free space on that drive drops below the size of the "\i386\" folder. If that should be fact, then delete the oldest one of the folders out there. Then the next copy step has enough free space to copy data over and over again, stressing the disks of a newly created host drive. (RAID)

To get the result code of robocopy, I use a runwait("robocopy sourcedir nextdestdir switches switches")

It looks like the adlibenabled function is never called? Maybe, adlibenable() is only executed, when

1.) the given timeframe is met AND...

2.) when the script is right now stepping from one line of code to the next one?

Or maybe my usage of Adlibdisable() / Adlibenable() is the reason, why it's never executed, because (possibly) every time I do so the timer will start from "0", so that the 1000 ms can never be reached?

Regards, Rudi.

I can think of a few issues:

1. Robocopy doesn't shut down properly, making the script hang at "RunWait()"

2. AdlibEnable() takes 250ms to trigger by default. If your While loop takes less time than that it will disable and enable, resetting the timer again. (seems the more likely)

Adlib is set to operate every 1000ms or every second, so the default 250ms is not being used. The while doesn't need to end because as soon as the while loop starts the function MakeNextDir() is called and the adlib function is disabled.That will happen a fraction of a millisecond after AdlibEnble I expect.

Hi.

Adlib is set to operate every 1000ms or every second, so the default 250ms is not being used. The while doesn't need to end because as soon as the while loop starts the function MakeNextDir() is called and the adlib function is disabled.That will happen a fraction of a millisecond after AdlibEnble I expect.

MakeNextDir() does a

- adlibdisable()

- create new destination directory

- update the array

- adlibenable() again.

The following robocopy will take few minutes. (... in case there is enough free space. Otherwise it will return immediately with an error)

It looks to me as if during the external program robocopy.exe is run, the autoit script itself is "sleeping", waiting for the "runwait('robocopy....')" to end, without executing the adlibenabled function every second?

I've worked around this issue by starting a 2nd script watching the free space and doing the cleanup, but I'm hoping I'm using adlibenable() not correctly yet, so that I could do so from *ONE* script.

You can use Run() instead, save the process id and check with ProcessExists() and the PID. This way, the Adlib function may have a chance to be executed.

I've thought of that, too. But I can't see how to catch the exit code of a program started through run() instead of runwait()?

I was referring to the one inside the loop, but that doesn't seem to be the problem.

I don't know robocopy, but I imagine you might be able to use StdoutRead(), or StderrRead()?
