Why have you commented out the lines
from the button 2 handler - unless you have pressed Button1 first, the connection has not been established and it will likely throw an exception - probably the one you are complaining about.
Personally, I would have a "Connect" method, which checked if you are connected and does so if not - and call it from both click events. (I would probably also make it return the stream instead of using a class level variable directly in the two event handlers).
If you get an email telling you that you can catch Swine Flu from tinned pork then just delete it. It's Spam.

I put back the
clientSocket.Connect("127.0.0.1", 8888);
serverStream = clientSocket.GetStream(); and it worked it connects now but the problem is with the button1 which send the text to the server, it stops at this line
clientSocket.Connect("127.0.0.1", 8888);

That's why I suggested that you had a routine which checked if you were connected - you don't need (or want) to connect if you are connected already!

Hope Im not requestion to much but would you like to write that if-statemant?
|
|

I dunno - it's soooo difficult....
if (!clientSocket.Connected)
{
...
}

I changed it to
private void button1_Click(object sender, EventArgs e)
{
if (serverStream == null)
{
MessageBox.Show("Please connect to a server.");
return;
}
readData = "Conected to Chat Server ...";
msg();
clientSocket.Connect("127.0.0.1", 8888);
serverStream = clientSocket.GetStream();
byte[] outStream = System.Text.Encoding.ASCII.GetBytes(sendTextBox.Text + "$");
serverStream.Write(outStream, 0, outStream.Length);
serverStream.Flush();
Thread ctThread = new Thread(getMessage);
ctThread.Start();
}
But still the same

Well yes - what did you expect.
The logic I suggested is not what you did:
if (not connected)
connect
TalkToServerWhat you did was
if (not connected)
Complain
else
{
connect
TalkToServer
}

Thank you mate I appreciate your help, I changed it to this code,
the reason I commented out
because the compiler stops there when I debugg telling me that a socket is already connected, now the compiler runs withour errors but the server consoleAppplication doesn't receive any msg at all when I send it from sendTextBox..
private void button1_Click(object sender, EventArgs e)
{
if (serverStream == null)
{
MessageBox.Show("Please connect to a server.");
return;
}
else
{
readData = "Conected to Chat Server ...";
msg();
serverStream = clientSocket.GetStream();
byte[] outStream = System.Text.Encoding.ASCII.GetBytes(sendTextBox.Text + "$");
serverStream.Write(outStream, 0, outStream.Length);
serverStream.Flush();
Thread ctThread = new Thread(getMessage);
ctThread.Start();
}
}
The compiler stops on this code under the getMessage method
serverStream.Read(inStream, 0, buffSize);

The compiler? What error message does it give?

"Failed to read data from the transport connection: An existing connection was forced to close by the remote host." It havens because I closed the Server... Anyway this project is driving me crazy man I can't see why it's not working and the Server doesn't get and show the string on the server prompt from the Client

I am going to write a C# 2010 application as a console application to start with. Eventually I will change the application to compile as a windows application so I do not get the dos pop windows. When this application goes into production, it will be executed by a windows scheduler. My question is the best way to pass parameters to this application.
Thus can you show me the following:
1. Code on how to accept values from parameters?
2. When the application runs as an executable, can you show me in code how to pass the values to this executable?

How to access command line parameters[^]. To execute a program with parameters you use a command line of the form:
program_name parameter1 parameter2 "a string parameter with spaces" parametr4 ...
|
|
|
|
|
There are several articles on here regarding parsing command line parameters. Here's one of the more recent ones:
Implementing command execution in a console application[^]
However, I caution you against expecting a Scheduled Task to be able to run a Windows application or anything that needs user interaction.
|
|
|
|
|
I would suggest that you are also likely to need a way to report on failures. So you might want to investigate that as well.
|
|
|
|
|
I see the others have you given you plenty to read regarding the parsing of parameters, so I will just add that it would be best to do ONLY the parsing of parameters and possibly writing of the help text in the Console application and put all actual program logic in a dll. That way you can plug any interface you want into your app: console window, windows UI, WPF, Web Service or whatever.

In a C# 2008 desktop application, I want to be able to check for a directory folder existing in a specified location. The directory path will look like C:\\main_folder\mm_yyyy. The mm_yyyy stands for the month and year.
Thus can you should be code on how to check if a folder actually exists?
|
|
|
|
|
|
I strongly recommend YYYY_MM instead.
|
|
|
|
|
I strongly agree!
To the OP: If you store file files as MM_yyyy, then the sort order is useless to you, no matter what you chose to sort by - because all the Januaries come before all the Februaries, and the years are then sorted within the month.
If you store by year first, you can retrieve the file names in "oldest first" or "newest first" without any additional processing.

Hi All, I've seen the reading of text from and writing of text to a file using C# StreamReader and StreamWriter. Also the file created is of type text. I was wondering if I can create various file types like CSS, HTML, JavaScript, etc simply by giving each file name an appropriate extension it requires. I don't have visual studio on hand so I can not test my idea. Thank you in advance for your reply.

You can create almost any type of file using StreamReader and StreamWriter.
|
|
|
|

Giving the file a valid extension will create that file. But the real question would be contents of the file. If you put valid html in a .html file than it is all fine but the moment you go ahead and start creating .exe files you will have to think how valid it is since you can not put a valid binary data in it.
So the answer to your question is yes but be careful about the file type you create.
Twenty years from now you will be more disappointed by the things that you didn't do than by the ones you did do. So throw off the bowlines. Sail away from the safe harbor. Catch the trade winds in your sails. Explore, Dream. Discover.
