Class Collection Problem (Continued)

[Joshua Russell]

Hi,
I don't quite understand what you are suggesting here. Can you please give
me an example of some real world code.

[Please read the conversation below to see what I'm on about]

Thanx Josh

Hi Joshua,
Isn't it better if you keep a map between users and threads. Hashtable will
do or you may go for your own collection based on DictionaryBase. You can
use the user ID as a key in the dictionary. When conversaion is started for
the first time you add a new entry in the dictionary.

In this case Process class won't help because ProcessThreads property
returns collection of ProcessThread objects, which are equivalent to the
"physical" window threads. .NET threads (Thread class) at the other hand are
platform independent objects. One "physical" thread may execute more then
one .NET threads. Currently there is one to one mappings but it won't be
like that in future.

Basically, I'm writing an MSN like chat client.
On each incoming chat request a new thread is created which in turn connects
to the server specified by the incoming request. If a conversation is open
for a specific user from a previous conversation I do not want another
thread to be started. I want to reuse the current thread. If a new request
comes in specifying a new server I will of course need to tell the

thread

to
disconnect from the old server and connect to the new server.
On an incoming request I will need some way of checking whether or not a
conversation exists already and if one does, some way of returning an object
reference.

Any ideas?

Thanx Josh

Hi Joshua,

Threads are not guarantee to have name thus, it is not possible to

have
such

a method.
In addition to what Nicholas said I would add only that WindowsForms
controls are bound to threads for the current implementation of .NET.

It
may

not be true for the future versions of windows.

Anyways look at System.Diagnostics.Process class.
You may find Process.Threads and Process.MainWindowHandle interesting.

If you explain in more details what you are trying to do we may come

up
with

some other solution for your poroblem.

message Hi,
is there a function wherby I can find a find a thread by its name. For
example, I want to get hold of a class referance for a thread named "My
Thread". I woudl like some code that looks like this...

ClassName myClass = Thread.FindByName("My Thread");

Basicaly I want to be able to do things like (presuming that myClass

is

a
form): myClass.Text = "New Title";

Anyone know how I can do this?

Thanx Josh
