Send shutdown command to an application?

[VAN0]

Hello.

Is there a way send shutdown command to a running process?

There are many intercept shutdown scripts, so I wonder if there is a way fake shutdown message and send it only to a specific process?

The process in question has no window, but has tray icon without menu.

 

Thank you.

Try WinClose() on the main menu.

Thank you.

It worked, but for some reason it "kills" the process, not gracefully shut it down...

How have you determined that as this is simply a Windows message being send to the Window and is the way to tell the application to gracefully close?
It is not like ProcessClose() which actually does hard kill the task.

[VAN0]

Well, when the application is killed via task manager or via winclose() the next time it started, it changes settings to default, when it closed gracefully via exit in tray menu (I lied about not having tray menu, because I don't want to use it), next time it launches it restores the settings.

This is what I've used:

Local $aProcessList = ProcessList("lcore.exe")
Local $aWinlist = Winlist()
For $i = 1 To $aProcessList[0][0]
    For $j = 1 To $aWinlist[0][0]
        If WinGetProcess($aWinlist[$j][1]) = $aProcessList[$i][1] Then
            ConsoleWrite("WinClose PID[" & $aProcessList[$i][1] & "] HWND[" & $aWinlist[$j][1] & "]: " & WinClose($aWinlist[$j][1]) & @CRLF)
        EndIf
    Next
Next

Ok, so guess you have the same issue when you hit the X at the right top of the window? 
Anyways, it is the Application not handling this correctly so you probably need to send the Exit option message to the window with WinMenuSelectItem().

[VAN0]

It doesn't have any GUI window that can close the application, just tray icon.

The reason why I don't want use tray menu, is because sometimes the application is not responding to right click, I was hoping it's not completely frozen and can still receive and handle shutdown commands. When it "freezes" and than system goes into reboot the application starts normally with all settings restored, so my hypotheses it's still responding to system's shutdown message.

So this is your own application you want to close?

[VAN0]

no, external application that giving me hard time, want create a script to restart it with a hotkey

[Jos]

Ok, so that external application still responds to the "Windows is shutting down" message but doesn't respond to the trayicon. 

You could try sending the .. to the app:

#include <WindowsConstants.au3>
$hWnd=WinGetHandle('your program window')
_SendMessage($hWnd, $WM_QUERYENDSESSION)

... maybe that works but haven't tested it.

Tested this on SciTE and seems to be working fine:

#include <SendMessage.au3>
#include <WindowsConstants.au3>
$hWnd=WinGetHandle('[CLASS:SciTEWindow]')
_SendMessage($hWnd, $WM_QUERYENDSESSION)
