Error reading excel using asp.net

Question

In my requirement, I am successfull in opening & reading Excel(both 2003 & 07) data from Asp.net OLEDB.

But it works only when Excel Sheet Kept open in our PC , Otherwise it gives 'External Table format error' .What exactly the problem ?.Can anyone show me light please. Is this anything problem with access rights?

Am sure Its nothing to do with connection string . My code

protected void Page_Load(object sender, EventArgs e)
        {
            string path = @"C:\Users\abcd\Desktop\raj.xls";
            connStr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + absoluteDir + ";Extended Properties=\"Excel 8.0;HDR=YES;\"";

            OleDbConnection oledbConn = new OleDbConnection(connStr);
            try
            {

                oledbConn.Open();
                OleDbCommand cmd = new OleDbCommand("SELECT * FROM [Sheet1$]", oledbConn);
                OleDbDataAdapter oleda = new OleDbDataAdapter();
                oleda.SelectCommand = cmd;
                DataSet ds = new DataSet();
                oleda.Fill(ds);
                GridView1.DataSource = ds.Tables[0].DefaultView;
                GridView1.DataBind();
            }
            catch (Exception err)
            {

            }
            finally
            {
                // Close connection
                oledbConn.Close();
            } 
        }

Thanks in advance
