How to find last active window ?

Recommended Posts

 

Simplified with the Winapi UDF:

#include <WinAPI.au3>
 $hPriorActiveWindow = _WinAPI_GetWindow(WinGetHandle("[ACTIVE]"),$GW_HWNDNEXT)
 WinActivate($hPriorActiveWindow)

Hi jdelaney, Thanks alot. That worked.. Thank you all for helping me.

My function is a bit different, because it returns only a visible Window.
You can try this code, it should return different values for the two functions :
 

#include <WinAPI.au3>
$hPriorActiveWindow = _WinAPI_GetWindow(WinGetHandle("[ACTIVE]"),$GW_HWNDNEXT)
$aPos = WinGetPos($hPriorActiveWindow)
ConsoleWrite("# Previous Window with _WinAPI_GetWindow: " & @CRLF & "HWND = " & $hPriorActiveWindow &  @CRLF & "Title = " &  WinGetTitle($hPriorActiveWindow) & @CRLF)
ConsoleWrite("Size : x=" & $aPos[0] & "; y=" & $aPos[1] & "; w=" & $aPos[2] & "; h=" & $aPos[3] & @CRLF & @CRLF)


$hPreviousWindow = _WinGetNextWindow("[ACTIVE]" , "", 2)
$aPos = WinGetPos($hPreviousWindow)
ConsoleWrite("# Previous Window with _WinGetNextWindow: " & @CRLF & "HWND = " & $hPreviousWindow &  @CRLF & "Title = " &  WinGetTitle($hPreviousWindow) & @CRLF)
ConsoleWrite("Size : x=" & $aPos[0] & "; y=" & $aPos[1] & "; w=" & $aPos[2] & "; h=" & $aPos[3] & @CRLF)

Thanks. Let me try. :)

      Hi everyone.
      I want to ask about this : 
      I want it runs from 1 to 100 and It opens 10 firefox profiles then access youtube. After I close a firefox window, the loop runs and wait for another window close until loop ends
      I have a loop like this.
      Func launch() Local $from = Int(GUICtrlRead($input1)) Local $to = Int(GUICtrlRead($input2)) If $to <> "" Then While $from <= $to Local $profile = $to _RunDos("start firefox.exe -p " & $profile & " -no-remote youtube.com") $to=$to+1 WEnd Else Local $profile = $to _RunDos("start firefox.exe -p " & $profile & " -no-remote youtube.com") EndIf EndFunc Is there any solution?
      Thank you!

      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!

      Good morning everyone

      I was playing a little bit with "Screen Capture" UDF, and I was trying to make a "Window" capture, but, since I made a GUI which through I fire the event "Capture", my GUI is captured as well, and I don't want to
      This is the line of code that makes the capture:
       
      _ScreenCapture_CaptureWnd($strScreenCaptureFileName, $objActiveWindow, 0, 0, -1, -1, False) And these are the lines of code which select the "active" window:
       
      Local $objCurrentWindow = 9999 If _IsPressed("01") Then $objCurrentWindow = WinGetHandle("[ACTIVE]") If $objCurrentWindow <> $objMyGUI Then $objActiveWindow = $objCurrentWindow EndIf EndIf Sorry If I made stupid mistakes
      Thanks in advance.

      Francesco
