I have had a problem with a 3rd party out-of-process com object that has a
tendency to crash. Of course, it causes problems when this exe crashes, so
I had to watch to determine when the exe exited. All I did was spin up a
thread that used something simliar to the following:

public void ThreadFunc()
{
Process[] processList =
System.Diagnostics.Process.GetProcessesByName("PROCESS.EXE");
if (processList.length > 0)
{
processList[0].WaitForExit();
// The process has exited
}
else
{
// could not find the process
}
}

Not sure if this is what you are looking for but hope this helps.

I'm running the new application by creating a new instance
this.mi = new MapInfo.MapInfoApplicationClass();
my project has a reference to a MapInfo dll - and when I create this
instance it starts the MapInfo app. It's separate process and
therefore I'm expecting it's running on separate thred - on the other
side - my app halts until the loading of MapInfo finishes so maybe
they're both running on the same thread?
I can get the MapInfo process using (I have a pointer - handler to
it):
Int32 pid = win32.GetWindowProcessID(this.miWin.ToInt32());
mapInfoProcess = Process.GetProcessById(pid);
but when I subscribe to Exited event it never gets fired?

I also tried to "subscribe" to the messages coming from MapInfo so I
can catch WM_CLOSE message but I can't get it working.
My code looks like this:
public delegate IntPtr MessageProc(int code, IntPtr wParam, IntPtr
lParam);
IntPtr hookHandle = SetWindowsHookEx(WH_GETMESSAGE,
hookFunction,IntPtr.Zero, AppDomain.GetCurrentThreadId());
public IntPtr NameOfYourFunction(int code, IntPtr wParam, IntPtr
lParam)
{
Message test =
(Message)Marshal.PtrToStructure(lParam,typeof(Message));
return new IntPtr();
}

Hi,
Is there any way in .NET how to capture WIN API messages that belong
to different application? We have a Windows Form app written in .NET
2.0 and from our application we're running another application called
MapInfo using Interop. We need to be able to somehow figure out when
the user exits the MapInfo applicaiton so we can close our own app as
well.
I was looking on SetWindowsHookEx function but couldn't make it work.
Thanks for any help
Jan
