Sending a mouse click to a window without focus

[Keikopute]

Hello all,

I know this topic has already been discussed multiple times but I can't figure out what is wrong with my code.
I would like to send a mouse click to a window without focus.

The following piece of code is creating a GUI with a "test" button. Clicking on the "test" button print a "ok" to the console.
When pressing the keys CTRL + P, the VirtualMouseClick() function is called.
This function calls the following :

_SendMessage($hwnd, $WM_LBUTTONDOWN, 1, _WinAPI_MakeLong($x1, $y1))
_SendMessage($hwnd, $WM_LBUTTONUP, 0, _WinAPI_MakeLong($x1, $y1))

Which should do what I want.. but it doesn't. Could you help me with it please ?
Thank you

Here is the code:

expandcollapse popup

#include <WinAPI.au3>
#include <WindowsConstants.au3>
#include <GUIConstantsEx.au3>

Opt("GUIOnEventMode", 1)
;~ Opt("MustDeclareVars", 1)

HotKeySet("^p", VirtualMouseClick)

Global $gui
Global $size[2] = [300, 300]

$gui = GUICreate("", $size[0], $size[1])
GUISetOnEvent($GUI_EVENT_CLOSE, "quit", $gui)
GUICtrlCreateButton("Test", 10, 10, 100, 80)
GUICtrlSetOnEvent(-1, "TestOk")
GUISetState(@SW_SHOW, $gui)

ConsoleWrite($gui & @CRLF)


While(True)
    Sleep(200)
WEnd

Func _ArrayFind($array, $item)
    Local $retour = False
    For $i = 0 To UBound($array) -1
        If($array[$i] = $item) Then
            $retour = True
            ExitLoop
        EndIf
    Next
    Return $retour
EndFunc

Func quit()
    Exit
EndFunc

Func TestOk()
    ConsoleWrite("ok" & @CRLF)
EndFunc

Func VirtualMouseClick()
    Sleep(100)
    Local $hwnd = WinGetHandle("[ACTIVE]")
    Local $x1 = 30
    Local $y1 = 50
    Local $isDown = 1
    ConsoleWrite("$hwnd = " & $hwnd & @LF)
;~  _SendMessage($hwnd, $WM_MOUSEMOVE, 0, _WinAPI_MakeLong($x1, $y1))
;~  Sleep(50)
    _SendMessage($hwnd, $WM_LBUTTONDOWN, 1, _WinAPI_MakeLong($x1, $y1))
;~  Sleep(50)
;~  _SendMessage($hwnd, $WM_MOUSEMOVE, 1, _WinAPI_MakeLong($x1, $y1))
    Sleep(50)
    _SendMessage($hwnd, $WM_LBUTTONUP, 0, _WinAPI_MakeLong($x1, $y1))

EndFunc

inactive window -> window without focus

[BrewManNH]

The handle you're getting in the function is the ACTIVE window's handle, not an inactive window, doesn't sound right to me.

 

[Keikopute]

Yes, it's because I want to keep it simple for now. Making it work in the active window, then I could do the same for an "inactive" window.

[BrewManNH]

How are you determining that it's not clicking the window? Is it clicking somewhere that it would indicate that it was clicked? Also, have you looked at ControlClick?

[Keikopute]

The (x,y) position I am sending are, accordingly to AutoIt Window Info, the position of the "test" button. That is why I think it should be working.

I tried ControlClick and it worked fine, but I specifically want to use SendMessage because I will need to send a click to a SDL window.

is this for game?

[Keikopute]

No, it's for interfacing with Cinderella software : http://www.cinderella.dk/csdl.html which is detected as a "SDL_App" by AutoIt Window Info Tool thus ControlClick doesn't work on client area.

Hello,

Can anyone help me please ? :-)

[232showtime]

so im guessing, if i press ctrl+p it will click the test button???

[Keikopute]

Yes exactly, it's supposed to click it because of those 2 messages :

_SendMessage($hwnd, $WM_LBUTTONDOWN, 1, _WinAPI_MakeLong($x1, $y1))
    _SendMessage($hwnd, $WM_LBUTTONUP, 0, _WinAPI_MakeLong($x1, $y1))

But it doesn't and I don't understand why. Do you have any idea ?

[BrewManNH]

Just out of curiosity, have you tried using ControlClick instead of using _SendMessage on the application? Just do something like this in you VirtualMouseClick function to see if it works with the application you're trying to automate.

Func VirtualMouseClick()
    Sleep(100)
    Local $hwnd = WinGetHandle("[ACTIVE]")
    Local $x1 = 30
    Local $y1 = 50
    Local $isDown = 1
    ConsoleWrite("$hwnd = " & $hwnd & @LF)
;~  _SendMessage($hwnd, $WM_MOUSEMOVE, 0, _WinAPI_MakeLong($x1, $y1))
;~  Sleep(50)
;~  _SendMessage($hwnd, $WM_LBUTTONDOWN, 1, _WinAPI_MakeLong($x1, $y1))
;~     ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') :  _WinAPI_MakeLong($x1, $y1) = ' &  _WinAPI_MakeLong($x1, $y1) & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console
;~  Sleep(50)
;~  _SendMessage($hwnd, $WM_MOUSEMOVE, 1, _WinAPI_MakeLong($x1, $y1))
;~  Sleep(50)
;~  _SendMessage($hwnd, $WM_LBUTTONUP, 1, _WinAPI_MakeLong($x1, $y1))
    ControlClick($hwnd, "", "", "left", 1, $x1, $y1) ;<<<<<<<<<<<<<<<<<<<<<<<<<<<<
EndFunc   ;==>VirtualMouseClick

This should click in the correct location of the window, regardless of whether it can see the control or not.

Just a quick reply... I was able to made it by sending PostMessage instead of SendMessage.
