I had the same problem the other day....

Does the config file that is in the project root directory differ from the one in the Debug directory? If I remember correctly, VS overrites the config file every time you compile or change some settings in the file.

Kind regards,

What about the <app name>.exe.config ? Is that perhaps different?

Otherwise run the Enterprise Library Configuration tool and set the values again in all config files....

Adding checkboxes in listbox in C#

Make sure you save your application. You will get this if the application is not saved OR if the app.config is missing.

Dynamic Actions based on dynamic command list

Re: Dynamic Actions based on dynamic command list

20-Aug-09 22:21

Hi all,

Okay, lets try to explain what I want to accomplish...

I have a multi threaded TCP/IP server. When a client connects and sends data to the server, the server responds with a 'ACK'. But I would like to be more specific with the client(s) request.

Lets say the client sends a command (which can be anything/dynamic) 'EVENT'. Now when the server receives this command, it must recognize it, and execute the code that is specific to the EVENT command. (maybe by using dynamic delegates or Action Confused | :confused:

)

The client must be able to have a variety of commands that it can send to the server ... this is already in place. The issue is, how can I dynamically accommodate the ever changing command(s) that the client(s) can send to the server? So that the server can execute the correct code based on the client(s) request?

I really hope that this makes sense.
Many thanks in advance.

kind regards,

I'd suggest to keep it as simple as possible;

ProcesCommand("EVENT", "Other params");

You'd have to write that method yourself, off course. It's easier to swap the contents of a variable then to swap the method that you're using.

You could also search CodeProject for some articles on creating scripts. You could then launch a (precompiled?) script, depending on the parameters that you receive Smile | :)

Is there any easy way to monitor the amount of bytes sent and received on http port 80? I don't want to monitor the content of packets, just number and size of packets is important to me.

Is TcpListener class suitable for this purpose?

Any help would be greatly appreciated

You can user PerformanceCounter component by setting CategoryName property to Network Interface and after selecting appropriate counter.

Hi
I`m trying to run timer on tick method after clicking the button and i dont really understand how it can be done.

can anyone help please D'Oh! | :doh:

??

for example :

private void button1_Click(object sender, EventArgs e)<br />
        {<br />
            myTimer.Enabled = true;  <br />
            //Run myTimer_tick  <br />
<br />
        }<br />
<br />
        private void myTimer_Tick(object sender, EventArgs e)<br />
        {<br />
          //Do something here<br />
        }<br />

Meysam Mahfouzi20-Aug-09 22:14

I suppose you are trying to do something like this:

private void button1_Click(object sender, EventArgs e)
{
    myTimer.Tick += new EventHandler(myTimer_Tick);
    myTimer.Interval = 2000; // once every two seconds
    myTimer.Enabled = true;
}

void myTimer_Tick(object sender, EventArgs e)
{
    MessageBox.Show("tick");
}

I want to open Firefox ever hour!

void myTimer_Tick(object sender, EventArgs e)<br />
        {<br />
            System.diragnostic.process.start("firefox);<br />
        }<br />
static void Listen()<br />
        {<br />
<br />
<br />
            while (true)<br />
            {<br />
                try<br />
                {<br />
                    data = new byte[1024];<br />
                    received = networkStream.Read(data, 0, data.Length);<br />
                    if (received == 0)<br />
                        break;<br />
<br />
                    string get = Encoding.ASCII.GetString(data, 0, received);<br />
                    var send = get.ToByteArray();<br />
                    //Console.WriteLine("Received from TCP Client: " + get);<br />
                    networkStream.Write(send, 0, send.Length);<br />
<br />
                    <br />
                    if (get == "rstartFirefox")<br />
                        timer1.Tick += new EventHandler(myTimer_Tick);<br />
                        timer1.Interval = 3600000; // once every two seconds<br />
                        timer1.Enabled = true;

here it doesn´t work! the code works great by a Button_Click!
What can i do that it works here?

musefan21-Aug-09 5:57

start by moving the following two lines to your constructor, and use it no where else

timer1.Tick += new EventHandler(myTimer_Tick);
timer1.Interval = 3600000

then after all the code you have posted add the following line to check what going on..

MessageBox.Show("get = " + get);

let me know what pops up and how many times.

                        timer1.Tick += new EventHandler(myTimer_Tick);<br />
                        timer1.Interval = open * 1000; <br />
                        timer1.Enabled = true;                                             <br />
                    }

what is the value of open?
How do you know that the Tick event is not being called?
