Poll Info Every 0.5 Seconds

Hai!

======== Details ========

I made a program to poll some info relative to what the user typed.

[as the user types; no submit button]

Since it was a loop, it polled a bazillion time per second. :)

My program took a chunk of CPU power to run [not really, but a hundred times more than it should], so I need a way to have it poll like every second.

I tried sleep, but it lagged the program extremely bad.

When I want to escape it, I hit Esc, but even set to sleep(500), it takes a good 7 seconds to stop [i have to mash or hold esc o.O].

Not sure why it would do that.

Is there a way to fix this loop delay?

======== Summary ========

So to summarize:

The program is working perfectly, except I want to delay its refresh rate.

When I delay it's refresh rate, user inputs are delayed extremely long.

O.o?

======== Code's syntax ========

//  Basically syntax looks like this:

Do{
    poll crap loads of info
    GUISetState()
    sleep(500)      // I'm pretty sure there is a different form of sleep that I dont know
}

Thanks for reading

RandomClown,

First, welcome to the AutoIt forums.

As you have discovered, using Sleep can make a script very unresponsive - basically because nothing happens during that pause.

There are a couple of ways to make your script a bit more responsive:

1. You could try using something along these lines:

While 1
    ; Poll user input
    $iBegin = TimerInit() ; Get current time
    While TimerDiff($iBegin) < 500 ; Loop until 500 ms have passed
        ; Look for exit buttons etc
    WEnd
WEnd

The inner loop allows you to look for other keypresses etc while waiting and the user input polling will only take place every .5 sec

2. Use Adlib to run a function every 500ms which polls the user input. Look in the Help file for more details on how to use it - the syntax is very easy.

I hope this helps.

Thanks! That seems to be exactly what I need.

I will try it when I get the chance

PS:

Thanks for the welcome!

I was actually a user on the forums before.

It seems the forums got an upgrade; I had to register my email address again.

I found something else in the help system. [the help feature sucks at finding things]

From the help system, I added a single line to the menu:

GUISetOnEvent($GUI_EVENT_CLOSE,"Quit")

& magic happens.

Its awesome

@OP

why don't you try the adlib functions. There you can specify after how many second should the function for polling data be called. Please check help file for :

AdlibEnable ()
