Recursiveness of HotKeySet Handlers

[Zohar]

Hi

 

If you create a small program with several HotKeys, for example for Alt-F1, Alt-F2, Alt-F3, Alt-F4, Alt-F5,

and then write a Handler function for them, you will notice this phenomenon:

 

If the actions that you do in response to these HotKeys are long actions,

by long actions I mean not something that take 1 second to finish, but more like 1 minute or so,

such as doing IE operations, playing amelody, or whatever,

then I found out that If you press one Hotkey, and it's being performed,

then you can press another one, while the first is still being performed, and the second one will be performed now, halting the first one that started.

Only when the second hotkey will finish, then the original first hotkey that was pressed, will resume.

 

My questions regarding this are:

1) How many keys can we press recursively? (is there a limit?)

2) Is there a way to tell AutoIt to stop one of them?

Like If I pressed Alt-F1, it's now working,

then I press Alt-F2, and in some cases Alt-F2 should Stop Alt-F1...

Is there a way to tell AutoIt that?

 

Thank you

Zohar,

- 1. There is indeed a limit - and AutoIt will tell you about ending the script to "Prevent stack overflow" or similar - but it is up in the several thousands depending on the specific machine. Read the Recursion tutorial in the Wiki to learn more.

- 2. To learn how to stop functions, read the Interrupting a running function tutorial in the Wiki which will explain all.
