Is ar able to synchronize the three threads?

ListViewItem item = listView1.Items[0]
string val = item.Text;
string desc = item.SubItems[0].Text

// Given code will get value for 1st column 
 string txt = listView1.Items[listView1.FocusedItem.Index].SubItems[0].Text;

string txt1 = listView1.Items[listView1.FocusedItem.Index].SubItems[0].Text; // For 1st column
string txt2 = listView1.Items[listView1.FocusedItem.Index].SubItems[1].Text; // For 2nd column
