What control are you using ?
I assume that you are not using the ado.net  !


you can connect excel file using OLED and read the data , then u can able to display it.

take a look at the following url.

http://vb.net-informations.com/excel-2007/vb.net_excel_oledb.htm

also u can read the data in usual way .

http://vb.net-informations.com/excel-2007/vb.net_excel_2007_open_file.htm


Heres some code I use to connect to an excel data range  :-



Using m_connexcel As OleDbConnection = New OleDbConnection(String.Format("Provider=Microsoft.Jet.OLEDB.4.0;" & _

         "Data Source={0};" & _

         "Extended Properties=""Excel 8.0;HDR=NO""", SPREADSHEET_NAME))

 m_connexcel.Open()

   Using cmd As OleDbCommand = New OleDbCommand(String.Format("SELECT  * FROM [{0}]", DATARANGE), m_connexcel)

    Using oRDR As OleDbDataReader = cmd.ExecuteReader

       While (oRDR.Read) 

          If Not oRDR.IsDBNull(oRDR.GetOrdinal("F1")) Then

            MsgBox(oRDR.GetString(oRDR.GetOrdinal("F1")))

          End If      

        End While

     End Using

   End Using

   m_connexcel.Close()

End Using



Set 'HDR' in the connection string to 'YES' if you want to use the first row as the field names, otherwise the fields will be calledF1, F2, F3 etc...

>> I´m not using excel, It´s Access file.

almost the same as provided for excel


See: http://www.startvbdotnet.com/ado/msaccess.aspx
Code for retrieving records 



Imports System.Data.OleDb

Public Class Form1 Inherits System.Windows.Forms.Form

Dim cn As OleDbConnection

Dim cmd As OleDbCommand

Dim dr As OleDbDataReader

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e as _

System.EventArgs) Handles MyBase.Load

End Sub



Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As_

System.EventArgs) Handles Button1.Click

Try

cn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;_

Data Source=C:\emp.mdb;")

'provider to be used when working with access database

cn.Open()

cmd = New OleDbCommand("select * from table1", cn)

dr = cmd.ExecuteReader

While dr.Read()

TextBox1.Text = dr(0)

TextBox2.Text = dr(1)

TextBox3.Text = dr(2)

' loading data into TextBoxes by column index

End While

Catch

End Try

dr.Close()

cn.Close()

End Sub

End Class

have you installed Windows 7 64-bits?
If this is the case, your VS2008 solution needs to target the x86 platform.
