""Cross-thread operation not valid: Control 'listView1' accessed from a thread other than the thread it was created on.""
I found this problem. How can I solve it.
My code:

ListViewItem item1 = new ListViewItem(sKW,0);

item1.SubItems.Add(sPos);
item1.SubItems.Add(sDate);

listView1.Items.AddRange(new ListViewItem[]{item1});
}

for(int i = 0 ; i < listView1.Items.Count;i++)
{

string sKW = listView1.Items[i].SubItems[0].Text; // i got error here
SearchKWinGoogle(sKW,i);
progressBar1.Value = i+1;

Accessing UI element from different thread is not possible. Most possibly your code is running under different thread. If so then you can change your code and run it under main (ui) thread. If you need to access it from different thread then simply read the value as you normally do. Only to update the control, you need to switch to GUI thread.
