Using dataset. OleDbConnection OleDbCon = new OleDbConnection( "Your Connection Strig" ); string strQuery = "SELECT COUNT(*) AS nCount FROM tblYourTable" ; if (OleDbCon.State == ConnectionState.Closed) { OleDbCon.Open(); } OleDbCommand OleDbCmd = new OleDbCommand(strQuery, OleDbCon); OleDbDataAdapter OleDbDa = new OleDbDataAdapter(OleDbCmd); DataSet dsData = new DataSet(); OleDbDa.Fill(dsData); OleDbCon.Close(); lblCount.Text = dsData.Tables[0].Rows[0][ "nCount" ].ToString(); Let me know its working or not.
