MS-Access

I am creating a connection string using ms access and saving the record in ms access data base.

My code is as follows in global function(Class file);

private string Accessconncetionstring ="Provider= microsoft.jet.OLEDB.4.0;Data Source=Data\\HIMTTESTing.mdb";

public void BindAccessConn()
{
      con = new SqlConnection();
      con.ConnectionString = Accessconncetionstring;
      con.Open();
}

public void InsertAccessData(string SQL)
{
      try
      {
          BindAccessConn();
          cmd = new SqlCommand(SQL, con);
          cmd.ExecuteReader();
      }
      catch (Exception e1)
      {
          Error = e1.Message.ToString();
      }
}

public SqlDataReader ReadAcessSql(string SQL)
{

      con = new SqlConnection(Accessconncetionstring);
      con.Open();
      cmd = new SqlCommand(SQL, con);
      dr = cmd.ExecuteReader();
      return (dr);
}

public string CntAcessString()
{
     return Accessconncetionstring;
}

//Save record code as follows;

private GlobalFunction GFun = new GlobalFunction();
private string sql;


private void BtnSaves_Click(object sender, EventArgs e)
{
      SaveDetails();
}

private void SaveDetails()
{
      //save coding starts
      try
      {
          string sql;
          for (int i = 0; i < datagridView.RowCount; i++)
          {
              for (int j = 2; j < datagridView.ColumnCount; j++)
              {
                    if(datagridView[j, i].Value != DBNull.Value && datagridView[j, i].Value !=  "" && datagridView[j, i].Value != null )

                  {
                      sql = "insert into Tb_SCh_TIme_Table(Date,Session,Course,Faculty_Code)" + " values ('" + Convert.ToDateTime(datagridView.Rows[i].Cells[0].Value.ToString()) + "', '" + int.Parse(datagridView.Rows[i].Cells[1].Value.ToString()) + "', '" + datagridView[j, i].Value.ToString() + "','" + datagridView.Columns[j].HeaderText.ToString() + "')";
                      try
                      {
                          GFun.Error = "";
                          GFun.InsertAccessData(sql);
                          if (GFun.Error.ToString() != "")
                          {
                              MessageBox.Show(GFun.Error.ToString(), "Error");
                              return;
                          }
                      }

                      catch (Exception Ex)
                      {
                          MessageBox.Show(Ex.ToString(), "Error");
                      }
                  }
              }
          }
      }
      catch (Exception Ex1)
      {
          MessageBox.Show(Ex1.ToString(), "Error", MessageBoxButtons.OK);
      }
}

In run time, all records are entered and the save button is clicked.
Error shows as follows;

KEYWORD NOT SUPPORTED 'PROVIDER';

I THINK IN THE BELOW LINE IS PROBLEM AS FOLLOWS.

private string Accessconncetionstring ="Provider= microsoft.jet.OLEDB.4.0;Data Source=Data\\HIMTTESTing.mdb"; <br />

HIMTTESTing is ms access data base name. In that database tables are there.

From my above code, what is the the mistake? How can i do? Help me.
