Send virtual key codes

[patrik2991]

Is there a way, like send, controlsend, to "emulate" a button press with virtual key code?

Virtual key codes

(_IsPressed get these virtual key codes, if someone don't know)

[Zibit]

i think this has to work with memory... i have no idea how you could do this but i hope you do cuz this would be a whole new step to autoit.

[Zibit]

try to use dllcall... that might be the way.

This post by Authenticity points in the direction you should go...

Sends 0x41 ("A") key.

DllCall('user32.dll', 'int', 'keybd_event', 'int', 0x41, 'int', 0, 'int', 0, 'ptr', 0)
DllCall('user32.dll', 'int', 'keybd_event', 'int', 0x41, 'int', 0, 'int', 2, 'ptr', 0)

Is there a more convenient way to send virtual keys?

[Melba23]

socap,

Just wrap those 2 lines in a function:

_Send_Virtual_Key(0x41)

Func _Send_Virtual_Key($iCode)
    If Not IsInt($iCode) Then Return
    DllCall('user32.dll', 'int', 'keybd_event', 'int', $iCode, 'int', 0, 'int', 0, 'ptr', 0)
    DllCall('user32.dll', 'int', 'keybd_event', 'int', $iCode, 'int', 0, 'int', 2, 'ptr', 0)
EndFunc

How much more convenient would you like it to be?

Mmm.... spoonfed code is delicious!

This works fine, but how can I direct to a specific window?

[Nine]

Depends on the application you are trying to send keys to : ControlSend is one way or _SendMessageA could work too. Otherwise, you will have to resort to put the application in foreground...

[Jonatas]

Thanks for the quick reply Nine!
Isn't there a way to use the specific "keybd_event" for a window?
Could you demonstrate an example of using with _SendMessage with notepad?

I researched it but didn't understand it very well

[Jonatas]

About _SendMessage, I found this perfect example of Oasis375

 

#include <SendMessage.au3>
#include <WindowsConstants.au3>

Run("notepad.exe")
$hWnd = WinWait("[CLASS:Notepad]", "", 10)
$hControl = ControlGetHandle($hWnd, "", "Edit1")
$text = "this is a line"
$struct_string = DllStructCreate("char[" & StringLen($text) + 1 & "]")
DllStructSetData($struct_string, 1, $text)
_SendMessageA($hControl, $WM_SETTEXT, 0, DllStructGetPtr($struct_string))

please tell me how to send a virtual key combination,

for example, Alt+a, "^a", "{LCTRL}a"

  When I send $VK_SELECT (SELECT key) nothing happens

_Send_Virtual_Key(0x29) ; -> VK_SELECT - SELECT key

Func _Send_Virtual_Key($iCode)
    If Not IsInt($iCode) Then Return
    DllCall('user32.dll', 'int', 'keybd_event', 'int', $iCode, 'int', 0, 'int', 0, 'ptr', 0)
    DllCall('user32.dll', 'int', 'keybd_event', 'int', $iCode, 'int', 0, 'int', 2, 'ptr', 0)
EndFunc

virtual key combination (Left CONTROL key + A)

DllCall('user32.dll', 'int', 'keybd_event', 'int', 0xA2, 'int', 0, 'int', 0, 'ptr', 0)  ;~  Left CONTROL key
DllCall('user32.dll', 'int', 'keybd_event', 'int', 0x41, 'int', 0, 'int', 0, 'ptr', 0)  ;~ A
DllCall('user32.dll', 'int', 'keybd_event', 'int', 0x41, 'int', 0, 'int', 2, 'ptr', 0)
DllCall('user32.dll', 'int', 'keybd_event', 'int', 0xA2, 'int', 0, 'int', 2, 'ptr', 0)

Thanks for the quick reply
It works very well!
I want to make this message more reliable, but I don't know how to send a combination to a control in a window.
Like this:

#include <SendMessage.au3>
#include <WindowsConstants.au3>

Run("notepad.exe")
$hWnd = WinWait("[CLASS:Notepad]", "", 10)
$hControl = ControlGetHandle($hWnd, "", "Edit1")
$text = "this is a line"
$struct_string = DllStructCreate("char[" & StringLen($text) + 1 & "]")
DllStructSetData($struct_string, 1, $text)
_SendMessageA($hControl, $WM_SETTEXT, 0, DllStructGetPtr($struct_string))

first sets input focus to a given control on a window using ControlFocus
then try your virtual key combination

If it's not feasible, I probably don't have a choice.
