Hi,

You will have to use a handler for each ping request. Probably now you get an error saying a previous Asynch request hasn't finished yet. Here's a part of your code and how I would handle it.

Add a tag to each panel with the name of the server.

So a for each panel loop

Code:

int i = 0;
            foreach (Panel p in this.Controls)
            {
                p.Tag = serverName.GetValue(i);
                i++;
            }

Create pinghandler (you have one so you can modify that one as needed):

Code:

        private void p_PingCompleted(object sender, System.Net.NetworkInformation.PingCompletedEventArgs e)
        {
            string server = (string)e.UserState;
            //server holds the name of the server and you can then find the right panel with that name as tag.
            //e.Reply.RoundtripTime.ToString() gives u pingtime if u want
            //e.Reply.Status.ToString() gives status in text

            if (e.Reply.Status == IPStatus.Success)
            {

                foreach (Panel panel in this.Controls)
                {
                    if (panel.Tag.ToString().ToLower() == server.ToLower())
                    {
                        //do your stuff ok
                        panel.BackColor = Color.FromArgb(128, 0, 256, 0);
                    }
                }
            }
            else
            {
                foreach (Panel panel in this.Controls)
                {
                    if (panel.Tag.ToString().ToLower() == server.ToLower())
                    {
                        //do your error stuff
                        panel.BackColor = Color.FromArgb(128, 128, 128, 128);
                    }
                }
            }

        }

And make a for each loop to loop through your servers and ping them:

Code:

foreach (var servername in serverName)
            {
                Ping p = new Ping();
                p.PingCompleted += p_PingCompleted;
                p.SendAsync(servername.ToString(), 1000, servername.ToString());
            }

cant understand the first part... and it ping all in same time ?!

cuz for example if a server has high latency it take several sec till app load fully .... and maybe people try to launche game on offline server before notice that ....
that's why i wanna send ping requests all at once ... BTW, if u expline first part ... since i don't use panel, i used an array .... i can't get panel and the tag ....

Hi I meant you use panels on your form where you color them. For the ping completed to know what panel to use, I use the tag of the panels to identify them. So the panels I mean are Panel1, Panel2 etc. I found them on the Form1.cs form. I assume that is the form that does the ping.

You fill an array of serverName (10 items max). And you have 10 panels.

Then add tag to Panel with:

Code:

            int i = 0; //counter for array of serverName
            foreach (Panel p in this.Controls) //loop through your 10 panels
            {
                p.Tag = serverName.GetValue(i); //set tag to serverName array entry with the number i
                i++; // go next i for next item in array
            }

The other ping completed code then has also the serverName for all the calls and you lookup[ the right panel and set the color to green (ok) or red (error).

And yes it does all the pings at the same time.

Code:

foreach (var servername in serverName) // loop through all servers
            {
                Ping p = new Ping(); // make new ping request
                p.PingCompleted += p_PingCompleted; // add handler
                p.SendAsync(servername.ToString(), 1000, servername.ToString()); //do asynch ping, so the loop keeps going because it is asynch. give max 1 second (1000ms) for a ping 
            }

I hope this clears it up

this function don't work ....
and give me error.. i tried this in refresh function and formload handler...


int i = 0;
foreach (Panel p in this.Controls)
{
p.Tag = realmList.GetValue(i);
i++;
}

and one more question, the way these things work, if the person filled 3rd server realm, and put empty for 1st and second... what will happen? it gonna show ping of 3rd realm in 3rd panel, while in listBox it's on 1st slot ?!

and the way u said it check all at once... so my application wont hang for min? since i still couldn't test that due to error ... it say "Unable to cast object of type 'System.Windows.Forms.ProgressBar' to type 'System.Windows.Forms.Panel'."


///////////
edit:
one more thing... what if i gonna add other panel to my application ?! since once may i need new functionallity that need other panel

[deadManN]

One more thing.. dunno why can't edit last post....

i see you use e server name to assign to ping class
but really serverName is teh name i show in listBox, but realmList is the IP or server Url .....
