Guys I am trying to use this to insert records into a database but I am getting this error: -
OleDbCommand dbComm = new OleDbCommand(strSql, objConnection);
Line 60: dbComm.Parameters.Add("@CategoryName", OleDbType.NVarChar, 15);
Line 61: dbComm.Parameters.Add("@Description", OleDbType.NText);
Line 62:
