            }
            listBox1.SetSelected(0, true);
listBox2.SetSelected(0, true);

int lineNum = 1;

foreach (string line in System.IO.File.ReadAllLines(myFilePath))
{
    if (lineNum <= 100)
    {
        listBox1.Items.Add(line);
    }
    else
    {
        listBox2.Items.Add(line);
    }

    lineNum++;
}
