Upload Data from Local System Ms Access to Web Sql Server? -

i have windows forms application maintains billing details of company's employees. application stores , manipulates data in ms access database. have send data every sql server web database employees can see monthly reports on website. code :

private sub uploaddata()    dim conn new oledb.oledbconnection("connection string ms access db")    dim scon = new sqlconnection(" web sql sever connection")         try             scon.open()         catch ex exception             msgbox(ex.message)             exit sub         end try    dim qcmd new sqlcommand("select query", scon)    dim cmd new oledbcommand("select id,acc,newacc,city,name,billduedateamt,oldbalance records city = 'delhi'", conn)    dim mrdr oledbdatareader = cmd.executereader         try             while mrdr.read                 qcmd.commandtext = "insert billing (acc,newacc,city,name,billduedateamt,oldbalance) values (" + _                         mrdr.item(0) + "," + mrdr.item(1) + ... on ")"                 qcmd.executenonquery()             end while         catch ex exception             msgbox(ex.message)                     if scon.state <> connectionstate.closed                 scon.close()             end if             conn.close()         end try  end sub 

it's slow, there better code so?

here short of code showing bulkcopy.

private static void performbulkcopydifferentschema() {     string connectionstring = @"server=         localhost;database=northwind;trusted_connection=true";     datatable sourcedata = new datatable();     // source data     using (sqlconnection sourceconnection =                     new sqlconnection(connectionstring))     {         sqlcommand mycommand =             new sqlcommand("select top 5 *              products_archive", sourceconnection);         sourceconnection.open();         sqldatareader reader = mycommand.executereader();         // open destination data         using (sqlconnection destinationconnection =                     new sqlconnection(connectionstring))         {             // open connection             destinationconnection.open();             using (sqlbulkcopy bulkcopy =                 new sqlbulkcopy(destinationconnection.connectionstring))             {                 bulkcopy.columnmappings.add("productid", "productid");                 bulkcopy.columnmappings.add("productname", "name");                 bulkcopy.columnmappings.add("quantityperunit", "quantity");                 bulkcopy.destinationtablename = "products_topselling";                 bulkcopy.writetoserver(reader);             }         }         reader.close();     } }
