There is little to no reliance on MFC in the article I provided. The author just used it as a convenience rather than a necessity. If you read through it, you will surely find the important parts, namely the parent/child hierarchy and which one to send the message to.

Can you please suggest me some way how to get the view Id ?
I suspect the answer will be in the form of sending a LVM_GETVIEW message.

Hello all,
I have made an MFC application with invisible window and invisible in Applications tab of taskmanager designed to run in different sessions depending upon the number of users who are logged into the system. Thus, according to user events the instances used to capture logoff/Shutdown/Logon events for that particular session.Also, I have made one instance of this executable to run in 'SYSTEM' account to capture scheduled shutdown in cases when no user was logged on the machine. However in this case 'WM_QUERYENDSESSION' is never recieved by this running instance of my application which runs in 'SYSTEM' account.Can some one tell me how to abort scheduled shutdown in Windows from an application running in system account , in a case when no user is logged on in the machine.
Regards,
Kushagra

I'm not sure that WM_QUERYSESSION is sent to apps running in system account. You could try SetConsoleCtrlHandler() and catch the CTRL_SHUTDOWN_EVENT. I don't think this allows you to stop the shutdown.

I got your point, but how do we use SetConsoleCtrlHandler in an MFC application..I can always do shutdown -a inside it if I recieve a CTRL_SHUTDOWN MEssage. Please Detail me how to include it in an MFC application ?

The MSDN article has a link at the bottom to an example. It's not MFC, but you should be able to use it in an MFC app.

Thanks Hans,
But yes we can only intercept the message here and not abort shutdown here

It will sound funny, where actually are you catching WM_QUERYENDSESSION Message?

Hey Alok,
I am trapping the message in WndProc(Windows Procedure Method) of the application. Then using the message handler for WM_QUERYENDSESSION I am returning false to abort logoff/shutdown and doing my functionality in between.

Where is this message being sent from? Is that process sending it to your window directly, or to all top-level windows via HWND_BROADCAST?

Hello David,
Generally when windows receives shutdown event it broadcasts WM_QUERYENDSESSION to all top level windows applications , here the issue is as my MFC application is running silently from 'System' account somehow the broadcasted message from Windows is not able to identify this as a Top level windows application.Hence, this application never recives the message whcih is why I am stuck here. All i need to do is to stop scheduled shutdown from a process running in 'System' account. I am open to suggestions , if this can be done in any other way too.
Regards,
Kushagra

I'm very familar with all of this. I was inquiring about the WM_QUERYSESSION message.

Most likely a typo since the heading of the post says WM_QUERYENDSESSION, don't you think?

One can choose to make assumptions, or not. I've been around long enough to know that folks don't always ask the right question.

I'm well aware of that and you are not the only one.
For the record my post wasn't meant as criticism as you seem to have understood it.

I am sorry It was a TYPO from my side  . But kindly suggest some way so that I can achieve my goal.

Do you receive the message if the window is visible? What about if it's running in a non-SYSTEM account?

I have made it invisible , and I recieve this message for all accounts other than SYSTEM account and they are working pretty neat , but only for this particular case for monitering scheduled shutdowns through system account my logic goes for a toss as the message WM_QUERYENDSESSION never comes to the application.

With services, there is the "Allow service to interact with desktop" option. Is there a similar option for an app running as the SYSTEM account?

I am afraid , I did not found any thing of such kind with an application running from System account.

You might want to also pose this question to the folks in the microsoft.public.vc.language newsgroup. Several sharp folks are active there.

From MSDN: "Console applications receive shutdown notifications in their handler routines. To register a console handler, use the SetConsoleCtrlHandler function.
Service applications receive shutdown notifications in their handler routines. To register a service control handler, use the RegisterServiceCtrlHandlerEx function."
Maybe that helps.
