hWnd, PID and Exe under cursor

[KaFu]

For sure , but here's my little example... needed the func for an app.

expandcollapse popup

#include <WinAPI.au3>
#include <WindowsConstants.au3>
#include<GUIConstants.au3>
Opt('GuiOnEventMode', 1)

$hGui = GUICreate("hWnd, PID and Exe under cursor", 350, 67, 244, 160, BitOR($WS_POPUP, $WS_BORDER, $WS_SIZEBOX), BitOR($WS_EX_TOOLWINDOW, $WS_EX_TOPMOST))
GUISetOnEvent($GUI_EVENT_CLOSE, "_Exit")
$label = GUICtrlCreateLabel("", 0, 0, 350, 200, 0, $GUI_WS_EX_PARENTDRAG)

GUICtrlSetBkColor(-1, 0xEEF1F6)
GUICtrlSetColor(-1, 0x000000)
GUISetState(@SW_SHOW)

While Sleep(50)

    $hWndCtrl = HWnd(_WindowFromPoint())
    $hWndWin = _WinAPI_GetAncestor($hWndCtrl, $GA_ROOTOWNER)
    $hWndPid = WinGetProcess($hWndWin)
    $hWndExeLoc = _ProcessGetLocation($hWndPid)
    $hWndExe = StringRight($hWndExeLoc, StringLen($hWndExeLoc) - StringInStr($hWndExeLoc, "\", 0, -1))

    GUICtrlSetData($label, "$hWndCtrl " & @TAB & $hWndCtrl & @CRLF _
             & "$hWndWin " & @TAB & $hWndWin & @CRLF _
             & "$hWndPid " & @TAB & $hWndPid & @CRLF _
             & "$hWndExe " & @TAB & $hWndExe & @CRLF _
             & "$hWndExeLoc " & @TAB & $hWndExeLoc)

WEnd
