Hello,

this simple script
Code:
#NoEnv
Loop,
{
   Process, Wait, AutoHotkey.exe
   Process, WaitClose, AutoHotkey.exe
}
ExitApp
produces a CPU load about 30 % on my office system.

Has anyone any idea why? Maybe a bug?

You haven't put any sleeps in your loop so it runs at extremely high frequency. This is not a bug, just bad practice.

Waits up to Param3 seconds (can contain a decimal point) for a matching process to exist. If Param3 is omitted, the command will wait indefinitely.

For Wait and WaitClose: Processes are checked every 100 milliseconds; the moment the condition is satisfied, the command stops waiting. In other words, rather than waiting for the timeout to expire, it immediately sets ErrorLevel as described above, then continues execution of the script. Also, while the command is in a waiting state, new threads can be launched via hotkey, custom menu item, or timer.

It works for me at 0% load (tested with notepad.exe). Have you tried using Process, Priority, , L and SetBatchLines in your script?

Hi,
I'm encountering an issue about this kind of commands and at the same time I saw this post and thought that this code may need correction :
Instead of this :
Code:
Loop,
{
   Process, Wait, AutoHotkey.exe
   Process, WaitClose, AutoHotkey.exe
}
ExitApp

this is enough :
Code:
   Process, Wait, AutoHotkey.exe
   Process, WaitClose, AutoHotkey.exe

No need to Loop then no CPU load.

Because the process command will wait by itself and proceed to the next line when the first contition (AutoHotkey.exe process existing) will be met.
The the second instruction will go to next line (wathever it is) , when the condition (AutoHotkey.exe process closing) will be met too.

Correct me if it's wrong
