How can i fill a C# listview by using foreach loop a column and another foreach for second column so that 2nd loop do not over write first

Instead of constructing a new ListViewItem you can construct it at the beginning:

 ListViewItem item = new ListViewItem();

Then if you want to set the first column:

 item.Text = "url ..." // Column 0 (Url)

To set the second column:

 item.SubItems.Add("time..."); // Column 1 (Time)

Then, at the end, add the ListViewItem to the list view:

 listViewCookies.Items.Add(item);

Edit, here's a modified example:

   listViewCookies.Columns.Add("TYPED URL", 300);
   listViewCookies.Columns.Add("TIME", 400);

        ListViewItem item = new ListViewItem();


        using (RegistryKey rk = Registry.Users.OpenSubKey(strSID + @"\Software\Microsoft\Internet Explorer\TypedURLs"))
        {
            try
            {
                foreach (string u in rk.GetValueNames())
                {

                    item.Text = rk.GetValue(u).ToString();


                }
            }
            catch { }
        }


        using (RegistryKey rk = Registry.Users.OpenSubKey(strSID + @"\Software\Microsoft\Internet Explorer\TypedURLsTime"))
        {
            try
            {
                foreach (string u in rk.GetValueNames())
                {

                    object val = rk.GetValue(u);

                    DateTime output = DateTime.MinValue;
                    if (val is byte[] && ((byte[])val).Length == 8)
                    {
                        byte[] bytes = (byte[])val;

                        System.Runtime.InteropServices.ComTypes.FILETIME ft = new System.Runtime.InteropServices.ComTypes.FILETIME();
                        int valLow = bytes[0] + 256 * (bytes[1] + 256 * (bytes[2] + 256 * bytes[3]));
                        int valTwo = bytes[4] + 256 * (bytes[5] + 256 * (bytes[6] + 256 * bytes[7]));
                        ft.dwLowDateTime = valLow;
                        ft.dwHighDateTime = valTwo;

                        DateTime UTC = DateTime.FromFileTimeUtc((((long)ft.dwHighDateTime) << 32) + ft.dwLowDateTime);
                        TimeZoneInfo lcl = TimeZoneInfo.Local;
                        TimeZoneInfo utc = TimeZoneInfo.Utc;
                        output = TimeZoneInfo.ConvertTime(UTC, utc, lcl);

                        item.SubItems.Add(output.ToString());

                    }
                }
            }

            catch { }
        }

        listViewCookies.Items.Add(item);

    }
