Identify process window

[Anteaus]

Requirement:

Launch a process wth Run()

Identify the window belonging to this process.

Wait until this window is in a minimised or trayed state.

Proceed with rest of code.

Bit I can't figure out is how to identify the window-title or other handle associated with the process-number, so as to determine the window state. Any ideas how to do this?

Since you are starting the process yourself, I would enumerate all the windows existing before running the process and then enumerate the windows after the process was initiated, then parse the list through the filter and get your new windows ID.

The filter is to make sure you are capturing the right window and not the one that was excedentally started by a user manually while you were waiting for the process to startup.

WinGetProcess() can filter it. For example, if your PID is 200, then you get the PIDs for the open windows and whichever one is 200 is your window.

Example:

$pPID = Run("notepad")
WinWait("Untitled")
$wPID = WinGetProcess("Untitled")

If $pPID = $wPID Then
    While Not WinState()
        Sleep(100)
    WEnd
EndIf

Func WinState()
    Return BitAND(WinGetState("Untitled"), 16)
EndFunc

Should've thought of that, yes, it's basically just a question of polling to find the right one.

Thanks.

Have a look at this:

Func _SetParentWindowPID($PID, $hGUI)
    $hWnd = 0
    $stPID = DllStructCreate("int")
    Do
        $winlist2 = WinList()
        For $i = 1 To $winlist2[0][0]
            If $winlist2[$i][0] <> "" Then
                DllCall("user32.dll", "int", "GetWindowThreadProcessId", "hwnd", $winlist2[$i][1], "ptr", DllStructGetPtr($stPID))
                If DllStructGetData($stPID, 1) = $PID Then
                    $hWnd = $winlist2[$i][1]
                    ExitLoop
                EndIf
            EndIf
        Next
        Sleep(100)
    Until $hWnd <> 0
    $stPID = 0

    If $hWnd <> 0 Then
        $nExStyle = DllCall("user32.dll", "int", "GetWindowLong", "hwnd", $hWnd, "int", -20)
        $nExStyle = $nExStyle[0]
        DllCall("user32.dll", "int", "SetWindowLong", "hwnd", $hWnd, "int", -20, "int", BitOR($nExStyle, $WS_EX_MDICHILD))
        DllCall("user32.dll", "int", "SetParent", "hwnd", $hWnd, "hwnd", $hGUI)
        WinSetState($hWnd, "", @SW_SHOW)
        _WinAPI_RedrawWindow ($hWnd)
    EndIf
    GUISetState()
EndFunc  ;==>_SetParentWindowPID

See if you adapt it. Can't remember where I got it from...
