C# How to display all instances of a loop in a label?

To fix the issue you can do My code check the 1st 3 messages of the twitter wall and looks for a string called "code". if its there it will echo "code available" and if its not it will echo "no code". Right now it echos 3 times for each message. , How about this:

function echo_messages($url,$max = 1) {
     $data = json_decode(file_get_contents($url));
     $counter = 0;
     foreach($data->data as $post) 
     {
        preg_match("/code/", $post->message, $code);        
        if (strlen($code[0])!= 0){
            echo '<div id="facebook">Facebook: Code Available</div>';
            return;
        }
        $counter++;
        if($counter >= $max) break;
    } 
    echo '<div id="facebook">Facebook: No Code</div>'; 
}

echo_messages('https://graph.facebook.com/234265435775/posts',3);

function hasCode($url,$max=1) {/*...*/}
echo "<div id=\"facebook\">Facebook: ".
    (hasCode('https://graph.facebook.com/234265435775/posts',3)?
      "Code Available":"No Code").
     "</div>";

this will help I am really not sure what you are wanting, but if it is to add all of your Mutants dangerQuotient to your label you will need to change your foreach statement to something like this. You are currently replacing the label's contents every iteration of your foreach loop.

label12.Text = ""; // or just delete the text in the designer
foreach(Mutant mutant in mutants)
{
    label12.Text += mutant.displayInfo() + "\n"; //  This will create a seperate line for each displayInfo
   // label12.Text += mutant.displayInfo();  //This will add them on the same line
}

help you fix your problem I am new to programming world, kindly be gentle and my question is why the label control does not displaying file name one by one when it is called in for each loop. My task is to read the folder which contains more files I need to read the file name and display in the label control but it is not working well for me, it is simple for all but I am a beginner Why I don't know find how to find out the mistake? , Here is a sample code using the background worker process

BackgroundWorker bw = new BackgroundWorker();
public Form1()
{
    InitializeComponent();

    bw.WorkerReportsProgress = true;
    bw.DoWork += bw_DoWork;
    bw.ProgressChanged += bw_ProgressChanged;
}

void bw_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
   label1.Text = "File Scanning --> " + e.UserState as string;     
}

void bw_DoWork(object sender, DoWorkEventArgs e)
{
    string imageloc = @"D:\Image";
    string[] files = Directory.GetFiles(imageloc);
    foreach (var item in files)
    {
       bw.ReportProgress(0, item);
       Thread.Sleep(1000);
    }
 }

protected void button1_Click(object sender, EventArgs e)
{
   if (!bw.IsBusy)
   {
       bw.RunWorkerAsync();
   }
}

it fixes the issue , Try this, this should work:

<div *ngFor="let item of requests; index as ix">
    ix: {{ix}} FirstName:<b>{{item.name}}</b>&nbsp;
    <button (click)="HandleRequest(true, ix)">Accept</button>
    <button (click)="HandleRequest(false, ix)">Decline</button>
    <label>{{requesStatus[ix]}}</label>

    <!-- or -->
    <label>{{(isAccepted[ix]) ? 'accepted' : 'declined'}}</label>
</div>

                     // in class level declare this
   requesStatus: string[] = [];
                     // or
   isAccepted: boolean[] = [];

                     // function to set and use in template
   HandleRequest(accepted, ix) {
      this.requesStatus[ix] = (accepted) ? 'accepted' : 'declined';
                     // or
      this.isAccepted[ix] = accepted;
   }
