To read an excel file with Excel Class in vb.net

[nudrat]

I have added a reference Microsoft Excel 5.0 Object Library in my project.
the code is as follows:
Dim myExcel As Excel.Applicati on ' Interface to Excel
Dim myWorkBookColle ction As Excel.Workbooks ' Workbook-collection
Dim myWorkBook As Excel.Workbook ' Single Workbook (spreadsheet-collection)
Dim myWorkSheet As Excel.Worksheet ' Single spreadsheet

Dim fdlg As OpenFileDialog = New OpenFileDialog( )
fdlg.Title = "VB.NET Corner Open File Dialog"
'fdlg.InitialDi rectory = "c:\"
fdlg.Filter = "Excel Files (*.Xls)|*.Xls"
fdlg.FilterInde x = 2
fdlg.RestoreDir ectory = True
If fdlg.ShowDialog () = System.Windows. Forms.DialogRes ult.OK Then
txtFile.Text = fdlg.FileName
End If

myExcel = GetObject(, "Excel.Applicat ion")
If myExcel Is Nothing Then
MessageBox.Show ("Could not load Excel.exe")
Exit Sub
End If
' initialise access to Excel's workbook collection
myExcel.Visible = True
myWorkBookColle ction = myExcel.Workboo ks
'open spreadsheet from disk

myWorkBook = myWorkBookColle ction.Open(txtF ile.Text, , False)
'get 1st sheet from workbook
myWorkSheet = myWorkBook.Shee ts.Item(1)
'display the spreadsheet
'myExcel.Visibl e = True 'Read Cell A2
Dim myCell2 As Object = myWorkSheet.Ran ge("A2", System.Reflecti on.Missing.Valu e)
Me.Text = myCell2.Value 'save and get out
myWorkBook.Save ()
myExcel.Quit()

now its giving error at this line
" myWorkBook = myWorkBookColle ction.Open(txtF ile.Text, , False)"

it gives Member Not Found. whereas .open is there in the list.
plz find the solution.
