_IsPressed and Keyboard buffer

[Mikesch]

Hi,

the following will work fine for about 2 seconds, sending "x" and "y" alternating, then output will be sorted. So if I press the defined $hotkey for some seconds, I'll end up with something like

xyxyxxxxxxxxxxxxxxxxxyyyyyyyyyyyyyyyyyyy.

Guess it has to do with the keyboard buffer or message queuing, but I can't find out why this would happen or how to avoid it.

Could you point me to the right direction, please?

Func Sendkeys()
    While _IsPressed($hotkey, $dll) = 1

        Send("x")
        sleep(100)
        Send("y")
        sleep(100)
    WEnd
EndFunc   ;==>Sendkeys

Thanks,

Mike

This may work better:

HotKeySet("{F1}", "_Sendkeys")

While 1
    Sleep(28800)
WEnd

Func _Sendkeys()

    Send("xy")

EndFunc ;==>Sendkeys

Hi billo,

thanks for your reply. I know your code would work, and I even don't have issues when using F-Keys with _isPressed(), but in this case the function should really only run as long as the defined key ("z") is held down. (The 100 ms delay is crucial, too.)

Send("x") and 'y' will be replaced later, probably with some ControlSend() commands I need for video cutting.

While testing I came about that strange behaviour and still can't see what I'm missing.

No Problem...

Maybe one of the more experienced coders will shed some light on the issue...

good luck!

I dont have problem with this when it is in main loop, you did not post the script that can replicate problem so its hard to know where problem is

#Include <Misc.au3>
While 1
    If _IsPressed("74") Then ;74 = F5   try not to use F1 becose it is mented for help in most of programs
        Send("x")
        Sleep(100)
        Send("y")
        Sleep(100)
    EndIf
WEnd

Edit: ok i know what did you do wrong

You did something like this probably

#Include <Misc.au3>
HotKeySet("{F5}","Sendkeys")
While 1
;~  If _IsPressed("74") Then Sendkeys()
WEnd
Func Sendkeys()
    While _IsPressed("74") = 1

        Send("x")
        sleep(100)
        Send("y")
        sleep(100)
    WEnd
EndFunc   ;==>Sendkeys

So if thats your problem delite hotkey and put ispresed in main loop (probably my crystal ball is working )

Oh, re-reading the script I think the problem occurs because I launch the function by hotkey, so the problem is not within the function itself, but in the way it is called.

Thanks, you helped me very much. "Main Loop" was the correct keyword.

Regards,

Mike

EDIT: Got me! ;-) Even before I did. Crystal ball functioning properly. Thanks again.
