OnTimer Application Exit problem

[AndrewX]

Hi, I need a timer to close my application after an hour so 3600000 ms.
I tried timers of all types including Global Timer Plugin, that I don't understand anyway.
My application has 5 pages, so jumping through the pages will restart the timer.

How I can exit on timer without problems?
Really thanks!

This will check your application's lapsed CPU time every minute, and then close your application at 60 minutes ...

Globals

i = os.clock()

Page On Show (for each page)

Page.StartTimer(60000, 10);

Page On Timer (for each page)

lapsed_secs =   os.clock() - i 
if lapsed_secs > 3600000 then
    Application.Exit(0);
end

Edit,

Oops, sorry - that's not quite correct. Lapsed CPU time gets measured in seconds (not millisecs) - so '3600000' should actually be adjusted to '3600' in the above example. And depending on how accurately you want things timed, you can also lose the variable from Globals, and instead just go with:

Page On Show (for each page)

Page.StartTimer(60000, 10);

Page On Timer (for each page)

i = os.clock();
if i > 3600 then
    Application.Exit(0);
end

So that fires each page timer every minute and shuts the application once elapsed CPU time has reached 3600 seconds (1 hour).

hello bio, how to reset the os.clock() to zero() if the time is reach?

@BioHazard
Thanks for the fast reply, I will try this new solution.
Hope i works!

hello bio, how to reset the os.clock() to zero() if the time is reach?

You don't reset os.clock() per se. It's a native Lua function which returns the number of seconds the CPU has been engaged by a given process. And resets to zero only after the process has been terminated. So instead, you'd write a count function and assign a dynamic variable to reset to zero at defined interval/s.

... My application has 5 pages, so jumping through the pages will restart the timer. How I can exit on timer without problems?

The os.clock() method posted above will work on multi-page apps, no problem. Is probably also the simplest & most concise method.

But you can use other methods across multiple pages, too. It doesn't matter that the timer gets restarted on page jumps - because values carry across pages, providing they're stored in global variables (all AMS variables are global in nature unless specified as local).

Attached is an example which demonstrates. This one uses a simple count-action to instruct the application when to close. Note how the variables are global in nature and carry their values across pages. Also, be sure to label the page timer correctly from each Page On Show event. (This example is set to close the application at '10' seconds. Just swap the relevant value for '3600' seconds if you want it to close after one hour).

telco,

Addendum to previous ...

hello bio, how to reset the os.clock() to zero() if the time is reach?

Attached for you is an example demonstrating how to reset a count to 'zero' at any predefined interval. (Uses a simple count-action attached to a dynamic variable). This is what you would use, not the os.clock() function.

Minor typos in above examples. (LOL, really must stop writing code when I'm tired).
Use these corrected versions instead:

Dear BioHazard, THANK YOU SO MUCH!
As usual, simple example, simple solution.
Very appreciated!

Only if you have time, how could this code operate a countdown?
From 10 seconds to 0 seconds time out, now it starts from 0 to 10 seconds.

I repeat, only if you have time.

Just simple maths

Globals
nCount = 10;

OnTimer
nCount = nCount - 1;
Paragraph.SetText("counter", nCount);
Paragraph.SetText("subheading", "Time Accrued:");
Audio.Load(CHANNEL_BACKGROUND, "AutoPlay\\Audio\\beep.wav", true, false);

if nCount == 0 then
    Paragraph.SetText("subheading", "Time Is Up!");
     Audio.Load(CHANNEL_BACKGROUND, "AutoPlay\\Audio\\timeup.wav", true, false);
     nCount = 10;
end

Good job, thanks for the suggestion.

I found an issue.
If I insert in the project a DialoEx, with the same Page code OnShow and On Timer, using DialogEx.StartTimer instead of page.StartTimer, all blocks!

Thanks for the suggestion but it seems doesn't solve my problem. I don't need another timer, I need dialogEx behavior the same as the page.

On each page I've

OnShow

Page.StartTimer(1000, 30);

OnTimer

nCount = nCount - 1;
if nCount == 0 then
Application.Exit(0);
end

OnGlobals I've

---Countdown 20 sec for testing
nCount = 20;
