What I took this to mean is that you will have to build a stack of your =

for all client connections and then when you call TcpListener.Stop(),
you'll have to loop through your stack and Stop() all of those =

that you can run across). I forget how the work-around went, but there =

some issue with the .NET framework where it reads in the *.config file =

sure that others on this list would know far more about these aspects of
Mono than I. In recent work for a software monitoring app which I have
written at work, I have forced a re-read on every cycle of the thread

things easier). =20

Subject: [Mono-list] Hello
Hello all,
=20
I just thought I'd introduce myself to the list before asking questions.
I'm a software developer by profession and I work on a free game server =
tool
in my spare time. After adding a server-side portion to my app, I got
several requests for Linux support and I started looking at C/C++ and C# =
as
an option. A co-worker told me about Mono and I started working with =
the
0.23 release. Great job! I'm very impressed with the progress so far -
it's a huge thrill for me to take a binary and watch it work on both =
Windows
and Linux. I'm very excited about the future!
=20
It's a simple TCP server that allows admins to have remote access to =
their
game consoles. So far, it's working pretty well, but I've come across a
couple things that, as far as I can tell, should be operational, but =
isn't
working for me. =20
=20
I just installed 0.24 on RH8 without garbage collection. The "make" =
failed
with an invalid "-lgc" option (problem with configure?). I've run into =
two
problems with TcpListener and FileSystemWatcher....
=20
[Newbie flame suit on]
I have a thread that calls "TcpListener.AcceptSocket()" and keeps =
looping
handling the new connection requests. This works great. However, when =
I go
to shut down, I call "TcpListener.Stop()" from a different thread and =
then
"Join" to wait for the server thread to exit. It never exists because =
the
server thread is still blocking on the "AcceptSocket()" call. Shouldn't
calling "Stop" interrupt the "AcceptSocket()" call? Or is that an =
invalid
assumption?
=20
Also, I want to use FileSystemWatcher to watch for changes to my cfg =
files,
but after setting things up, it appears that after making changes to =
files
in the watched directory, the changed event never fires. It does work =
on
Windows, however. I do not get an exception - nothing happens. I'm =
using
the "FileSystemWatcher/FileSystemEventHandler" method rather than the
"WaitForChanged" method (I see that's not implemented yet :-).
[Newbie flame suit off]
=20
I can post code if it's relevant...
=20
Thanks,
Terry
