ControlSend is sending keys everywhere

[WalrossGreat]

Hi, I have problem with au3.
For example i have code like it:

ControlSend($game, "", "", "S")
Script is sending S, but when i open firefox, he is sending it to $game and to Firefox. After 5 minutes keyboard are getting bug. Keyboard is having press space/shift all the time etc. What is wrong? Is it au3 bug?

You are not the only one. When I experimented with ControlClick, it was really weird as well. If you have any alternative, I would recommend you not to use ControlSend

Try SendMessage, this should only click / send the window.

Ok, I'm having

Local $hWnd = WinGetHandle("Notepad")
MsgBox("", "", $hWnd)
    If @error Then
        MsgBox("", "", "An error occurred when trying to retrieve the window handle of Notepad.")
        Exit
    EndIf
While 1
	_SendMessage($hWnd, 32)
	Sleep(300)
WEnd

But it is doing nothing after run script.
I found only it:

https://www.autoitscript.com/autoit3/docs/libfunctions/_SendMessage.htm

and the second parametr - $iMsg should be a number. It mean number of key, or what?

[alpines]

No, it's the number of the message. w and l Param define the keys and position. There are plenty examples on the internet.

you should use Control Get Handle

;#Example
$Hwnd = WinGetHandle("[ACTIVE]","") ;click on active window
$Cwnd = ControlGetHandle($Hwnd, "", "")

controlsend($Cwnd, "", "", "")

just example. not correct code ofcourse.
