If you want to create MS Access data base and to access it, and to display data in some component, like here i will show you.how to connect with MS Access Data Base and display data from data base in Label. First of all create any Access data base like here "PirFahimDataBase". Now in your Visual Studio go to the menu and do this

1. Click Data
2. Add New Data Base
3. Click Next
4. Click New Connection
5. Now change the Data Source by clicking Change and select Microsoft Access data base files
6. Click Browse for selecting your created data base

Now in Button ClickEvent paste these code which will get data from data base and will show it in the label

using System.Windows.Forms; //these two lines should be written before namespace at top of the program
using System.Data.OleDb;

private void button1_Click(object sender, EventArgs e)
    {        
      System.Data.OleDb.OleDbConnection conn = new System.Data.OleDb.OleDbConnection();
     conn.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;" +
    @"Data source= C:\Users\pir fahim shah\Documents\PirFahimDataBase.accdb";

    try
     {
     conn.Open();
     MessageBox.Show("connected successfuly");
     OleDbDataReader reader  = null;  // This is OleDb Reader
   OleDbCommand cmd = new OleDbCommand("select TicketNo from Table1 where Sellprice='6000' ", conn);
    reader = cmd.ExecuteReader();
    while (reader.Read())
    {
     label1.Text= reader["TicketNo"].ToString();           

    }

}
    catch (Exception ex)
{
    MessageBox.Show("Failed to connect to data source");
}
finally
{
    conn.Close();
}    
 }//end of button click event
