Insert Into Visual Foxpro Error...

Question

I am trying to insert data into a vfp table named tblVFP1.dbf, which has 142 fields. I just want to insert the first 2 fields while leave other 14o fields intact, but I got the following infomation: ro_stock is not allowed to be empty.... When I include this fileld in string---s another similar error info prompt indication other fields are not allowed to be empty... It seem that all fields are required to insert one record to my table, so I changed my code to: //// all the 142 fields are included in string s. string s="insert into tblVFP1 (ro_repref,ro_account,ro_stock..........)" + "values ('"+s_repref+"','"+ro_account.............+"')"; try { OleDbCommand cmdt=new OleDbCommand(); OleDbCommand cmdt0=new OleDbCommand(); cmdt0.CommandText="SET NULL OFF"; cmdt0.Connection=connt; cmdt0.ExecuteNonQuery(); cmdt.CommandText=s; cmdt.Connection=connt; int i=cmdt.ExecuteNonQuery(); operaConnt.Close(); MessageBox.Show("rows inserted into opera PPO="+i.ToString()); } catch(Exception ee) { MessageBox.Show(ee.Message); } but when implementation, I got the following error: too many argument. What is wrong with my program? I am sure the connection I built is right.. thanks
