How to gracefully end a process without using CloseMainWindow

Is there a way to gracefully end a process without using Process.CloseMainWindow()?

I have a bunch of processes in a list which I want to end. The process should be ended without Process.Kill() to make sure they clean up and end their child processes as well. I tried CloseMainWindow, but unfortunately it will make my process pop up a messagebox with "Do you really want to end the programm?"[Yes][No] which I want to avoid.

The processes have a message handler for WM_QUERYENDSESSION but when I tried to send a WM_QUERYENDSESSION message to the process, it didn't react on it. It just reacts on WM_QUIT, but the behaviour looks like the one when calling Process.Kill().

I couldn't find a proper solution yet. Hopefully I didn't overlooked things in here...

Well after a while I admit that there seems to be no real answer to this explicit problem.

Since I got control of both parts I just removed the "Do you really want to quit?" pop up like IInspectable assumed and send a message via the opened pipe to the child process like Sefe assumed.

Sending the WM_CLOSE message is pretty much the same as clicking the close button on a window. Applications will be able to block this request or put up a "Save your changes" confirmation dialog.

Anything beyond this and you risk loosing data. WM_QUIT is not something you should be sending.

WM_QUERYENDSESSION is a query, you would send that first and then WM_ENDSESSION but not all applications will handle these messages.

Win32 does not have a main-window property, it is a .NET concept.

Another thing you should look into is the restart manager feature if you plan on restarting these applications again when you are done with whatever you are doing.
