string sqlquery = "insert ati_log_io (date, connect_time, disconnect_time, ati_rep, reason_for_access, property_contact, case_number, comments, property_id)"; sqlquery += " values (@today, @connect, @disconnect, @rep, @reason, @contact, @casenum, @comments, @propertyid)"; using (sqlconnection dataconnection = new sqlconnection(connectionstring)) {     using (sqlcommand datacommand = new sqlcommand(sqlquery, dataconnection))     {         datacommand.parameters.addwithvalue("today", datetime.today.tostring());         datacommand.parameters.addwithvalue("connect", txtindate.text + " " + fromhrs.text + ":" + frommins.text + ":00");         datacommand.parameters.addwithvalue("disconnect", txtoutdate.text + " " + tohrs.text + ":" + frommins.text + ":00");         datacommand.parameters.addwithvalue("rep", repid);         datacommand.parameters.addwithvalue("reason", txtreason.text);         datacommand.parameters.addwithvalue("contact", txtcontact.text);         datacommand.parameters.addwithvalue("casenum", txtcasenum.text);         datacommand.parameters.addwithvalue("comments", txtcomments.text);         datacommand.parameters.addwithvalue("propertyid", lstproperties.selectedvalue);          dataconnection.open();         datacommand.executenonquery();         dataconnection.close();     } }

copy-paste should trick
