How to find last active window ?

[kcvinu]

 

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.

Hi 

jguinch,

However, i am going to try your function.

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 :
 

expandcollapse popup

#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)

 
 
; #FUNCTION# ====================================================================================================================
; Name ..........: _WinGetNextWindow
; Description ...: Retrieves a handle to the next or previous visible window in the Z-Order.
; Syntax ........: _WinGetNextWindow($vWindow[, $sText = ""[, $iCmd = 0]])
; Parameters ....: $vWindow             - The title/hWnd/class of the window. See Title special definition.
;                  $sText               - [optional] The text of the window to check. Default is an empty string. See Text special definition.

;                                         This parameter can be either of the following values :
;                                          $GW_HWNDNEXT (2) : Returns a handle to the window below the given window.

; Author ........: jguinch
; Remarks .......: If the specified window is a topmost window, the function searches for a topmost window.

Thanks. Let me try.
