Hi All.
In preparation for exam 70-310, i've been working a chat
application (refer to Lab 4 in MCAD/MCSD Self-Paced
Training Kit) that consists of a server-activated
remotable object (ChatCoordinator.dll), a console
application that configures the ChatCoordinator object
(Server.exe), and a client console application
(Client.exe) that sends messages to the ChatCoordinator
which then sends the messages to other clients.
The application works fine while running on my local
machine, but when I try to run the Client from a machine
on my network I get the following error:
Unhandled Exception: System.IO.FileNotFoundException: File
or assembly name ChatCoordinator, or one of its
dependencies, was not found.
File name: "ChatCoordinator"
at ChatClient.Run()
at ChatClient.Main()
Does anyone have any ideas? I can post the Class modules
and/or the configuration files.
Regards,
Chad

Yes, you must deploy the ChatCoordinator assembly with your client even
though the ChatCoordinator will run on another machine. Your client must be
able to access the metadata of the remote object you are creating, the
ChatCoordinator. I have this book and this example tries to keep things
simple in order to understand the basics. There are ways around deploying
your remote object's assembly with your client. Check out step #5 on this

Thanks Sam,
That was very helpful. Hopefully you can help me again. I've expanded upon the example in the book. I've replaced the Server.exe with a Windows Service name HomeChatServer that calls RemotingConfiguration.Configure(Central.config) when the service starts. I've replaced Client.exe with a multi-class/module Windows Application. The initial form (SelectNameForm.vb) displays a listbox of usernames (populated by an Xml Web Service). Once the user select a username they are sent to another form (ChatClientForm.vb) that has two RichTextBoxes (one displays all the messages and one is for data entry of a new message). There is a class (ChatClient.vb) that interacts with ChatCoordinator.dll in much the same way as in the example in the book, except that instead of writing messages to the console it raises an event that is handled by the ChatClientForm which then writes the message to the Display RichTextBox.
My problem is compiling. How do I reference the ChatCoordinator.dll when compiling an assembly? In the books example they compiled a single file, like so:
vbc /r:ChatCoordinator.dll Client.vb
Thank you very much for your time and your help.
Many Regards,
Chad

It should work the same way essentially. The /r option on the vbc command
is short for /reference which means the assembly files listed after the /r
command will be referenced as part of the compile of the main assembly or
executable being compiled. Copy the ChatCoordinator.dll assembly to the
directory where you are compiling your Client.vb program. If you are
developing within Visual Studio you can also simply add the
ChatCoordinator.dll as a reference in your References folder underneath your
project.
Thanks,
Sam
