Hi!

I'm trying to add items to listbox from another class,the information pass to the funtion but the listbox dosen't seem to update. this is my code:

Main class (FORM) :

C#

public partial class Form1 : Form
    {
        
        public Form1()
        {
            InitializeComponent();
            
        }
// the function that updates the listbox
public void logURI(string OutputLog, string Information, string JOB)
        {
            try
            {
                listBox1.BeginUpdate();
                listBox1.Items.Insert(0, DateTime.Now.ToString() + " : " + JOB + " " + Information);
                listBox1.Items.Add("1");
                listBox1.EndUpdate();
                textBox1.Text = JOB;
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

}

Second Class:

C#

 public class FtpFileSystemWatcherTS
    {
 Form1 logs = new Form1();
logs.logURI( "", "Found folder modefied today (" + FileName.TrimEnd(), ") ElectricaTS");

Dear Mitran,

As you are calling the function in Form1 in order to fill the list box but as the classes are different and the ListBox1 is located in one form hen you need to paas the Listbox as the parameter into the function in order to get it filled accordingly.

logs.logURI( "", "Found folder modefied today (" + FileName.TrimEnd(), ") ElectricaTS",listbox1);

I hope yo understand where you are going wrong.

Thanks
