high cpu usage?

[Jabberwock]

Anyone want to try and explain why such a simple program is using soo much cpu load while running in the background? seems to do it with any hotkey.

HotKeySet("{F11}", "hello") 

While 1 
Wend
Func hello()
Send("Hello")
Send("{Enter}")
EndFunc

You need to add a sleep in your script, if all your doing is hotkeys you could do:

HotKeySet("{F11}", "hello") 

While 1
    Sleep(1000000)
Wend

Func hello()
    Send("Hello {ENTER}")
EndFunc

Or if you want to use things inside your loop as well you could just put a GuiGetMsg() in it, instead of a sleep.

That's a good point marf, I wonder if there is a default delay for GuiGetMsg() like there is for AdlibEnable().

Edit:

The test I did looks like 10 milleseconds... but I'm not sure if that was programmed that way. (I'm sure it was)

I always (most of the time ) do a

While 1
   $msg = GetGuiMsg()
   ; select switch or if
   if $msg = 0 then sleep(250) ; or as long as I dare, nothing to do anyway
WEnd

But as @SmoKe_N pointed out you don't need the GuiGetMsg when only using hotkeys.

and it's useless if using GUIOnEventMode.

[w0uter]

he just wants this. dont confuse him

HotKeySet("{F11}", "hello")

While 1
Sleep(10)
Wend
Func hello()
Send("Hello{Enter}")
EndFunc

and it's useless if using GUIOnEventMode.

That depends on 2 things, if 1, you actually have a reason for using Opt('GUIOnEventMode', 1) (like using a GUI) and 2, if you don't mind a Sleep(250) in Uten's example every time (which I agree is a waiste in that aspect), becuase with Opt('GUIOnEventMode', 1), then GUIGetMsg() returns 0 every time (thus the Sleep(250)).

Either way you need the loop and this script sample will probably grove. So why not learn "good" habits? Sleep as long as you dare (to off load your system) but not to much either because you will miss something important.
