Just call this script from your application.

You may refer to these posts for sample code.

It's in the same package.

From the code I see, you are creating a TcpClient. If your question is how to use the same TcpClient object to send another message without recreating the instance, then, you need to store TcpClient instances in a List, say listOfActiveClients, then everytime before sending check if the client is connected or not, then send the data.

Apologies, my bad, please try updated solution.

Use TcpClient's Connected property to determine if the client is connected to host or not.

If you use Sockets for communication then, you can use the Poll method to determine if the socket is connected or not.

so basically you want to check if the client is connected or not before sending the message?

If yes, then you can queue the message and try sending, if client is disconnected or has closed the socket, then handle the exception and re-try.

Alternatively, in many architectures, it is client's responsibility to send keep-alive token to server at regular intervals so that server knows client is connected.

I believe you are not importing a namespace there when you say System.Collections.Generic.List(Of System.String), you should just try aliasing to import System.Collections.Generic or System.Collections.Generic.List

then, what's the problem here?

MVC is just a design pattern, it only changes the abstraction level, but the essence should be the same.

What did you try, a WIX setup?

I did not get your point here, out of multiple clients that connect to server, if a client does not specify whom to send data, how will sever determine that? You need to tell this to server somehow or build that logic in server that will hardwire C1 with C2.

You can put that information in the message body, the server can then parse this information from there. i.e.

C1 should send something like {"Receiver:"C2", "ReceiverIP":"a.b.c.d", "Message":"Hello, I am C1"}

then S can parse Receiver information and send the message to C2

{"Sender": "C1", "SenderIP": "1.2.3.4", "Message":"Hello, I am C1"}

Upon receiving this the client can parse the message and determine who sent the message and what is the message.

You may come up with a better architecture.

Well you did not mention "web" in your question, but, apparantly if you are using ASP .NET controls you'd be setting the runat property to server (runat="server"). This ensures that any value change in the textbox will cause a postback and will also hit your TextChanged event where you can add the behavior you require.

This should help you. It has an example as well.

Hmmm, I went by what Josh said, that, only ContactType is not a string and I believe that is the place where the implicit typecast would fail.

If that is the case, I need not ask him to provide the Contact class or the custom collection he has defined.

In essence, WriteLine automatically adds the new line after the text, you need not enter a newline. The reason it is not working is because what I mentioned above.

This will not work as StreamWriter is being disposed after writing to the file. Next time while writing the second line, new StreamWriter will again point to start of file i.e. line 1.

You would need to seek to the end of file and then write in this case. That is what the overload of StreamWriter does.

using (StreamWriter sw = new StreamWriter(@"C:\Users\MyPC\Desktop\test.txt", true))
{
sw.WriteLine(res);
sw.Flush();
}

I just gave an example for the tool, different tools might have different ways to integrate. You may find a tool that supports command line and then invoke it from your routine.

In case you want to write your own tool, you can take help from the suggestions here.

There are tools to do that, you can use them or write your own.
Here's a tool which does that. http://dbweigher.com/dbwscript.php

This will help you read tables from MS Access
http://stackoverflow.com/questions/1699897/retrieve-list-of-tables-in-ms-access-file

Once you have table schemas, you can create the same in SQL, then copy data.

unless you are targeting any OS specific assembly, this should not be a reason.

If the user/client is making modifications via your application then you may implement a custom service command to notify your service of the change.

you may try to dump the response stream just to check if the data returned is correct?
