Timeout help

[Ryan]

I have a script that pulls variables from other programs.

But every now & then, one of the programs will suddenly terminate or just freeze.

So what im looking for is:

1. When the program freezes, the data on the script will also freeze, so i need to make a "timeout" future, so when the variables haven't changed for a minute, then it will inform me about it.

2. When the program terminates, there script wont receive a variable, so how do i make it so when, that script dosent have a variable, then it informs me.

I know its something like If $var ="" then. or something like that, but i cant get anything to work.

You could just code a loop based on TimerInit()/TimerDiff().

You could create an AdLib function (Prod: AdLibEnable(), Beta: AdLibRegister()).

You could add timers to your GUI with _Timer_SetTimer().

Exactly how are you retrieving the variables from the other apps? For example, if you use ControlGetText(), it will return @error if the GUI or control doesn't exist any more.

Im using ControlGetHandle.

But what im looking for is.

I have a "X: $Var" and that $var should be changing ever 1 second. But if the program that im getting the var from freezes, Then the var will stay the same.

So if "X:35" and it stayed like that for 30 seconds, then the script would inform me about a possible problem.

Hi there,

And what about the process if it is an exe file?

Just an idea... we have few info about all your reality

Wish you the best.

Well, there's not much to that... this demo monitors for the window closing, failing to read the control, or a 30sec timeout. Note that AdLibRegister() is Beta, use AdLibEnable() for Prod.
