Openconnection Issue

[xtab]

Hi Friends,
i have written code for openconnection.show that if connection is really open it should simple return true.or if connection does not open.then it should return falso.but i am getting following errors.
The best overloaded method match for 'MakeConnection.Form1.OpenConnection(ref System.Data.OleDb.OleDbConnection)' has some invalid arguments D:\chash\MakeConnection\MakeConnection\Form1.cs
(2)Argument '1' must be passed with the 'ref' keyword
(3)No enclosing loop out of which to break or continue

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data.OleDb ;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace MakeConnection
{
    public partial class Form1 : Form
     {

       OleDbConnection conn = new OleDbConnection();


        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {   
         if ( ! OpenConnection(conn)== true) 
                {
               MessageBox.Show("Connection is Not Open");
               break;
                  }

        }
        private bool OpenConnection(ref OleDbConnection conn)
        {
            try
            {
                conn = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Imp\abc.mdb");
                conn.Open();
                return true;
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
                return false;
            }
        }

    }
