Problem reading excel data

I want to import an entire Excel into a DataGridView.

Public Sub Excel()
    Dim conn As OleDbConnection

    Dim dta As OleDbDataAdapter

    Dim OpenFileDialog As New OpenFileDialog

    Try
        OpenFileDialog.InitialDirectory = My.Computer.FileSystem.SpecialDirectories.MyDocuments
        OpenFileDialog.Filter = "All Files (*.*)|*.*|Excel files (*.xlsx)|*.xlsx|CSV Files (*.csv)|*.csv|XLS Files (*.xls)|*xls"

        If (OpenFileDialog.ShowDialog(Form1) = System.Windows.Forms.DialogResult.OK) Then

            Dim fi As New FileInfo(OpenFileDialog.FileName)
            Dim FileName As String = OpenFileDialog.FileName

            conn = New OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fi.FullName + ";Extended Properties=Excel 12.0;")
            dta = New OleDbDataAdapter("Select * From [" + FileName + "$]", conn)
            Dim ds As New DataTable("Excel")
            Dim dt As New DataTable
            dta.Fill(ds)
            Form1.DataGridView1.DataSource = ds
            conn.Close()

            With Form1.DataGridView1
                .RowHeadersVisible = False
                .Columns(0).HeaderCell.Value = "Direcciones"
            End With

            Form1.DataGridView1.ColumnHeadersDefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter
        Else
            Exit Sub
        End If
    Catch ex As Exception
        MsgBox(ex.ToString)
    End Try
End Sub

I see that I have problems with the name of the file or something similar...

At the moment I have copied the content to a notepad and read it from there line by line, but for future occasions I would like to know how to do it... Thanks! :)
