dotnet interop: Hi.=20

I'm developing a C# app which is starting another, old,=20
c++ app using the Proces class in .NET. I have a problem=20
with the C++ app.=20
In the destructor of the c++ app, some methods is called=20
to free some external resources to some POS hardware=20
through OPOS. But this destructor does not seem to be=20
used when i do one of the following things:=20
1. Call the Kill() of the proces class=20
2. call the Close() on the proces class=20
3. call the dispose() on the proces class=20
4. call the CloseHandle(IntPtr handle) of the Kernel32=20
5. pres ctrl+alt+del and kill the proces manually.=20

no matter what i do it seems that the destructor of the=20
c++ app is never called.=20
Can this be true?=20

Well if you kill a process it doesn't get a chance to do cleanup work.
If you want it to clean up properly, don't kill it.

Neither of these should terminate the process.

Do they run when you launch the app in another way (from command line
or Explorer for example). If not, why do you think this is
framework/C# related? Perhaps you should post to a C++ group instead.
