connecting and using access to store data from .net

This can be used in either a windows application OR an asp.net file.

NOTICE: if using with asp.net file the access file MUST be placed and refered to in the ROOT directory of IIS.


ok, first make the reference

using System.Data.OleDb;

to open and close connection....

OleDbConnection thisConnection = new OleDbConnection(
@"Provider=Microsoft.Jet.OLEDB.4.0;" +
@"Data Source=E:/WEB_SERVER/server_user_database.MDB");
thisConnection.Open();
//work here//
thisConnection.Close();

to add data...

OleDbCommand new1 = new OleDbCommand("INSERT INTO tablename (column(s)) values('valueshere')", thisConnection);
new1.ExecuteNonQuery();

to retrieve data...

OleDbDataReader myReader=null;
OleDbCommand test = new OleDbCommand("select * from tablename, thisConnection);
myReader = test.ExecuteReader();
while(myReader.Read())
{Label1.Text=(myReader["columnnamehere"].ToString());};
myReader.Close();

always close connection!!!...

thisConnection.Close();
