Send() in inactive window

Recommended Posts

Rhidlor

I was wondering if there was a library or something which provides the capability to Send() to inactive windows, and I know what you're thinking, I could just use ControlSend(); the reason I can't use that in this situation is because I need to hold down keys for specific prolonged periods of time. Also activating the window, Send()ing then de-activating the window isn't really an option here, I need the target window to always be in the background. I've looked around the forums for an adequate amount of time and didn't find anything useful, perhaps because the threads were all 10 years old, nevertheless, if anyone has any suggestions they would be greatly appreciated.

Thanks!

You could use _WinAPI_PostMessage() and send WM_KEYDOWN to hold the key down, sleep some time and WM_KEYUP to release it.

#include <WinAPISysWin.au3>
#include <WindowsConstants.au3>

$hWnd = WinGetHandle("Your window")
$iVkCode = 0x45 ; A key, see https://docs.microsoft.com/en-us/windows/desktop/inputdev/virtual-key-codes

_WinAPI_PostMessage($hWnd, $WM_KEYDOWN, $iVkCode, 0)
Sleep(100)
_WinAPI_PostMessage($hWnd, $WM_KEYUP, $iVkCode, 0)

However, please note that handling such messages is up to the receiving window. Some developers code their message receiving routine in such way that it only processes messages if their window is in foreground (active and in focus). Changing such behaviour is probably not possible with AutoIt, since you'd have to do some reversing on the application in order to hook and rewrite their message loop (and you would have to create a DLL for that).

Additionally, Windows includes an additional LLKHF_INJECTED flag in keystrokes sent by other applications, if it's not a keyboard driver. Thus, an application can find out whether a keystroke came from the user's keyboard or it was simulated by another application (and block these inputs) simply by setting a low level keyboard hook and checking for that flag. In this case, you would have to develop a driver.

      Hello all!   I'm stuck at a seemingly simple part of my script. Using IE, I'm filling out a web form that involves clicking a "Browse" button and selecting a file. Once the file explorer dialog opens, however, I am unable to control it.
      I have a string, which is the name of the file I want, and I'm trying to insert it into the 'File name:' text box in the dialog (which already has focus), but it doesn't get inserted. I've tried ClipPut and Send. 

      What's even more concerning is, when I close the dialog, the string is then pasted into the very next window that has focus, which is often SciTE. It's like that Browse's file open dialog halts all processes. Once it's closed, the script continues.
      ;~ Open a IE window and navigate to the login page. Global $oIE = _IECreate($urlBBLogin) _IELoadWait($oIE) ;~ Recognize the form on this page (login input boxes). Local $oForm = _IEFormGetObjByName($oIE, "login") Local $oTextLogin = _IEFormElementGetObjByName($oForm, "user_id") Local $oTextPass = _IEFormElementGetObjByName($oForm, "password") ;~ Enter the Automation user credentials into the form. _IEFormElementSetValue($oTextLogin, $bbUsername) _IEFormElementSetValue($oTextPass, $bbPassword) ;~ Click the Login button. _IEFormSubmit($oForm) _IELoadWait($oIE) ;~ Navigate to the feedfile upload page. _IENavigate($oIE, $urlUpload) _IELoadWait($oIE) ;~ Click the Browse button Local $Browse = _IEGetObjById($oIE, "feedFile_chooseLocalFile") _IEAction($Browse, "Click") Local $Browse = WinWait("Choose File to Upload") ;~ Open the file we created. WinActivate($Browse) Send($finalFile) Has anyone else experienced this problem? Any ideas to get around it? Am I approaching this the wrong way?
      Any support is greatly appreciated.
      Thank you.

      here's some PHP code to access AutoIt functions from php: 
      https://github.com/divinity76/autoit_php -
       
      as of writing, only 5 functions are added: MouseMove and MouseClick and _ScreenCapture_Capture and WinWaitActive and Send,

      it also has support for running in Cygwin (which is where i've developed it, but it *should*, in theory, run on normal php-cli for windows as well.), is there any community interest for this? 
       
      example usage
      <?php require_once("autoit.class.php"); $au = new AutoIt(); $au->MouseMove(10, 10, 5); $au->MouseClick("left"); echo "waiting up to 5 seconds for notepad window.."; if($au->WinWaitActive("[CLASS:Notepad]","",5)){ echo "found notepad!\n"; $au->Send("hello from autoit_php"); }else{ echo "timed out while waiting for notepad.\n"; } $imageBinary = $au->_ScreenCapture_Capture(); var_dump(strlen($imageBinary), imagecreatefromstring($imageBinary));  

      (i wanted to use some autoit functions from php-cli, and google wasn't of much help this time..)

      Hi,
      The FAQ proposed as a solution to keys getting stuck  to do this command
      ControlSend("", "", "", "text", 0) However this sends "text" to the last active control if I am not mistaken.I have tried this with
      controlsend("", "", "", "{altup}{shiftup}{ctrlup}", 0) This is already a lot better but still fails 1/10
      I cannot allow the script to send "text" to the last active control, and its a bit silly to let it send to somewhere where its harmless no?
      Are there any other methods of unstucking keys?

      Hello!
      I have made a program, that opens a folder, and then store the path ("C:\programFiles\etc") in a variable.
      Then i need to open the command panel as administrator, and write  in the stored path, and some other text.

      Can i somehow instantly copypaste the text i needed, instead of writing in the command panel with the Send commands?
       
      #RequireAdmin #include <MsgBoxConstants.au3> Global Const $sMessage = "Select a folder" ; Display an open dialog to select a file. Global $sFileSelectFolder = FileSelectFolder($sMessage, "") If @error Then MsgBox($MB_SYSTEMMODAL, "", "Nem választottál ki mappát!") Exit EndIf Global $Tiff_path = $sFileSelectFolder & "\TiffChecker_2_32" FileCopy( "C:\TiffChecker_2_32.exe" , $sFileSelectFolder) $CMD = $Tiff_path & " " & $sFileSelectFolder & " /s/d" Run("C:\WINDOWS\system32\cmd.exe") WinWaitActive("C:\WINDOWS\system32\cmd.exe") Send($CMD) Sleep(1000) Send("{ENTER}") sleep(1000) MsgBox(0,"Press OK", "Press OK to continue") FileCopy("C:\Tiffchecker.txt", $sFileSelectFolder) Also, how do i close the command panel, when the program is finished? (usually its under 1 second, so after the send i just put a Sleep function there)
