First, it's obvious you have no clue what you're doing or even how to talk about it. You have to define EXACTLY what you mean by an "online working program" because that can mean anything. Is this a Windows Forms application? WPF? A web application (ASP.NET)? What is this app supposed to do and under what circumstances.

Idk how to talk about it. It is an c# windows form application. I send a data from wfa-server to client by internet and when datas arrive to clients they do different jobs by coming datas means. But the biggest problem here is sending datas on internet. Server send 'a' to internet and then what ? Where should it go ? Idk how to online things works. o_o

What's a "wfa-server"?

Nothing is ever sent "to the internet". Data is sent over the internet using various protocols and formatting. Which protocols and which formatters you use depends on what your application is going to do. Without that definition, your just wandering aimlessly with target to write code to.

dude i know programming. Im not a beginner. i made this style program before but it was only working on lan. Now im working on a program which is communicating on internet.

Dave Kreskowiak 13-Sep-15 10:47am

Really? You're using a terms only a beginner would use and you're not providing any depth of knowledge of your problem at all, again, like a beginner would. You're just guessing at every turn.

Doing something over the internet is no different than doing it over a lan. The only minor difference is that there are probably NAT routers in the way that have to be configured properly to forward traffic to the appropriate machines.

Ok. What type of informations you need ?
"for solve my problem"

a little advise, read the yellow pannel located below the page -second item

2. Understand that English isn't everyone's first language so be lenient of bad spelling and grammar.

And im saying this again "like a begginer" im not a begginer

You really haven't been reading my posts. I already asked you a bunch of questions and considerations that you haven't said anything about.

Humaku 13-Sep-15 15:26pm

1.what you mean by "online working program"? --- online working program mean is a program which is sending different types of datas using internet to clients. It's not hard to understand

2.Is this a Windows Forms application? --- Yes its a Windows forms application.

3. What is this app supposed to do and under what circumstances.

For example : i have server application and the other person have the client. I send int "000" values to client. After values arrive, client trasfers it in a variable. Then its start to thinking what is "000" mean. Oh, its mean shut down the pc. After this logical codes client's pc will shutting down.Ofcourse client send a veriable to cliend to say "mission complated" Do you understand this. i know its some hard to understand this "with my bad english" isnt it ?

4.Which protocols and which formatters you use depends on what your application is going to do?

I dont know which protocols are necessary for this project. If you know you will say me.

it should support file transfering(*jpg ,*txt ...) but its not important for now. If i can send different types of variables its enough for me.

4. only minor difference is that there are probably NAT routers in the way that have to be configured properly to forward traffic to the appropriate machines.

if it's easy as you said, why don't you help me ?

Am i missed any question??

So the only thing you have this system doing is a server telling a client to shutdown. Well, that's going to prevent you from sending back a "success" message.

There's a bunch of different ways of doing this, but your clients will probably be "checking in" with a central server when your application starts. This check-in message should have the machine name and the current IP address to let the server know that the client is "alive", listening and on what address it's listening. It should then go into a "server" mode, listening for connections from the central server.

In all cases, your servers would probably be easiest to implement using a web service and all message passing done through XML formatted messages. This lets you easily implement passing various messages of whatever you want without worrying about the details of how the message is formatted and how to parse them.

Google for "C# web service" for more information.

As far as as how "easy" it is, that depends on your experience. Yeah, it's easy for me because I've been writing code for over 30 years. You?

Why haven't I helped you directly? Because I can't read your mind and up until now I haven't gotten any clue as to what your application was doing. YES, IT MATTERS. There is no one method for two way communication between machines. I f you have no idea what your application is going to be doing and how you want it to work it's pretty much impossible to write code to do it now, isn't it?

Humaku 13-Sep-15 21:21pm

Your answer is completely true. You answered all my questions which are i didn't asked :) .I'm feeling good because you read my mind. if, client send a "ok" variable, client program must have a server and servers must constantly check. But i didn't understand one thing. in all your messages you want to learn what I want to do. I dont have to complete a project or i dont have any idea what could this program do when it finish. if we can send a data correctly , we will be succeed. then we can do everything. if(comingData = "007") textbox1.text = "tnx dave"; :) can we do this with windows form aplicatins ?

And last thing is im a begginer against you.
I've been writing code for 4 years. i have a long time in my life. meybe im not a professional yet but im trying. One day me too help other people to write codes and i will say I've been writing code for over 30 years. That day i will remember you.when i look at you i see my future... i'm grateful for all your helps...
