  I am using the following code to connect to sql server with visual studio. i have added the ODBC source also as my database name: PermissionsTest.

  Actually when i debug the code then it gives error, but via wizards it is connecting to sql server.

  using System;

  using System.Collections.Generic;

  using System.ComponentModel;

  using System.Data;

  using System.Drawing;

  using System.Text;

  using System.Windows.Forms;

  using System.Data.SqlClient;

  using System.Data.Odbc;

  using System.Data.OleDb;

  using System.Data.Sql;

  namespace WindowsApplication5

  {

  public partial class Form1 : Form

  {

  public Form1()

  {

  InitializeComponent();

  SqlConnection myconn = new SqlConnection();

  myconn.ConnectionString =

  "Data Source =PERMISSIONSTEST;User ID=a;Password=a_password;app=Microsoft® Visual Studio® 2005;wsid=A-9";

  myconn.Open();

  SqlCommand cmd = new SqlCommand("select * from accountinfo",myconn);

  SqlDataReader myreader = cmd.ExecuteReader();

  myreader.Read();

  }

  }

  }

  IT GIVES ERROR:

  SqlException was unhandled

  It gives this error on the line : myconn.Open()
