hi,
I'm trying to write a multi client chat app using remoting. however atm, I'm
stuck when a userA tries to send userB a msg... say there're userA, userB
and userC. on the server side how do I know which user is userB when I
recieve message from userB ?
what should the process be. I know I need to store a reference of the
clients somehow on the server. but how can this be done ?

I’m trying to build a generic Publisher-Subscriber that will work over the
net, so I’m using the Remoting.
I wish that the subscriber user will be notify about the messages sent by
the remote publisher, so I used delegate that the user will be able to set on
it his own function for that purpuse.
The trouble is that this delegate must not be static because there may be
many subscribers, and each subscriber may have different...

I don't know where is the right place to ask this so I will start here.
Can someone explain to me what these represent? I think they all have to do
with the middleware level, but I really don't understand what a DCOM Server
is or a Microsoft Transaction Server, etc. I have no idea....

Hi All,
I am just trying to get an opinion here. I know this is always a tough
choice to make.
We are in the process of converting our VB6 based Healthcare Information
System (a full-fledged package) to .NET. Our clients have been asking for
lot of new stuff namely being able to send patient information to devices,
being able to fix appointments online, etc.

I'm programming in VS C++.NET 2005 using cli:/pure syntax. In my code I have
a class derived from Form that creates an instance of one of my custom
classes via gcnew and stores the pointer in a member. However, I set a
breakpoint at the destructor of this instance's class and it was never
called!!! I can see how it might not get called at a deterministic time. But
NEVER?
So, I guess I need to know the rules about destructors. I would...

I'm reading the book "Programming .NET Components" by Juval Lowy, a renowned
..NET expert as recognized by MSFT. In the book he provides a base class
example that implements a pattern for safely cleaning up your objects
(handling "IDisposable", etc.). His class calls a (do-nothing) virtual
"Cleanup()" function from its destructor however (we're supposed to override
it) and I'd like to confirm that this is in fact safe. Presumably it is but...

Hi
I have a problem with the .Net-Securty-Functions.
I've got a client and a server.
When I try to register a channel at the server with this line:
ChannelServices.RegisterChannel(chan, false);
I get the following error - doesn't matter if I try it local from my machine
or from a remote machine.
(After the Errormessage is more text ;))

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
