using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class Default2 : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{

}
protected void Button1_Click(object sender, EventArgs e)
{
String Query = "Select meaning from words where word like '%" + TextBox1.Text + "%'";
String Query2 = "Select mufrid from words where word like '%" + TextBox1.Text + "%'";

String strConn = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\MUFRIDAT_UL_QURAN1.mdb;Persist Security Info=False";



OleDbConnection Conn = new OleDbConnection(strConn);
Conn.Open();
OleDbDataReader dr = null;
OleDbCommand cmd = new OleDbCommand(Query, Conn);
dr = cmd.ExecuteReader();
while (dr.Read() == true)
{
TextBox2.Text = (dr["meaning"].ToString());
}

dr = null;
