Code:

---

                        try
                        {
                                foreach( DataRow dtrow in ds.Tables[0].Rows)
                                {
                                       
                                        string mmicr,msortcode,maccount,msrl,mserial,mamount ;
                                        mmicr = dtrow["micr"].ToString().PadLeft(6,'0') ;
                                        maccount = dtrow["account"].ToString().PadLeft(6,'0') ;
                                        msortcode = dtrow["sortcode"].ToString() ;
                                        msrl = dtrow["srl"].ToString() ;
                                        mamount = dtrow["amount"].ToString().PadLeft(13,'0') ;
                                        mserial = dtrow["serial"].ToString() ;
                                        OleDbDataAdapter danew = new OleDbDataAdapter(
                                                "UPDATE " + dbfname + " set micr = '" + mmicr + "',account = '" + maccount + "',sortcode = '" + msortcode + "',amount = '" + mamount + "',srl = '" + msrl + "' where serial == '" + mserial  , Dconn);
                                        DataTable dtnew = new DataTable() ;
                                        danew.Fill(dtnew) ;
                                }
                        }
                        catch (Exception exp)
                        {
       
                                MessageBox.Show(exp.Message) ;
                        }

You're creating a DataAdapter and passing it the SQL for an UPDATE command. No, no, no! When creating a DataAdapter in that manner you must pass it the SQL for a query, i.e. a SELECT command. The SelectCommand property, which is created from the SQL that you pass, is used to Fill a DataTable and the DeleteCommand, InsertCommand and UpdateCommand are used to commit changes back to the database when you call Update. You need to read up in the help or on MSDN about the OleDbDataAdapter and OleDbCommand classes, and perhaps take a look at some of the tutorials and/or 101 samples from my signature.

Thanks for your reply,

i am on the wrong way, i think i have to read a lot . but please wait for my next reply .

hi jmcilhinney,

i have a doubt, the way i tried to update the table is wrong as you said and i must agree with that ,. but the fact is , the coding is updating the table (syntax error is there in query string) , it is a free table of foxpro . can you please say how can this happen
