private void btnLoad_Click(object sender, EventArgs e)
{
using (OleDbConnection oleDbConnection = new OleDbConnection())
{
oleDbConnection.ConnectionString = this.tbCS.Text;
OleDbCommand oleDbCommand = new OleDbCommand();
oleDbCommand.CommandText = this.tbCT.Text;
oleDbCommand.Connection = oleDbConnection;
using (OleDbDataAdapter da = new OleDbDataAdapter(oleDbCommand))
{
DataTable dt = new DataTable();
da.Fill(dt);
dataGridView.DataSource = dt;
