Answer 1

i solve my problem time ago but i saw many user visiting this Question so i think i should answer my question to help others

1. I have 64 bit operating system

2. having 32 bit MS Office so for this we can not sure that what oledb connection version we have to use so for this we have alternate library from Microsoft to integrate ms office products to our applications.

   Microsoft.Office.Interop

to download and install this library follow this link Interop

and bellow is my code sample for further help

    Dim table As New DataTable("CurrencyRate")
    Dim OFD As New OpenFileDialog
    Dim strDestination As String
    With OFD
        .Filter = "Excel Office|*.xls;*.xlsx"
        .FileName = ""
        If .ShowDialog() <> Windows.Forms.DialogResult.OK Then
            Return False
        End If
        strDestination = .FileName
    End With

    Dim xlApp As Microsoft.Office.Interop.Excel.Application
    Dim xlWorkbook As Microsoft.Office.Interop.Excel.Workbook
    Dim xlWorkSheet As Microsoft.Office.Interop.Excel.Worksheet
    Dim xlRange As Microsoft.Office.Interop.Excel.Range

    Dim xlCol As Integer
    Dim xlRow As Integer

    Dim Data(0 To 3) As String

    With table
        .Clear()
        If strDestination <> "" Then
            xlApp = New Microsoft.Office.Interop.Excel.Application
            xlWorkbook = xlApp.Workbooks.Open(strDestination)
            xlWorkSheet = xlWorkbook.ActiveSheet()
            xlRange = xlWorkSheet.UsedRange

            If xlRange.Columns.Count > 0 Then
                If xlRange.Rows.Count > 0 Then
                    For xlRow = 2 To xlRange.Rows.Count 'here the xlRow is start from 2 coz in exvel sheet mostly 1st row is the header row
                        For xlCol = 1 To xlRange.Columns.Count  
                            Data(xlCol - 1) = xlRange.Cells(xlRow, xlCol).text
                        Next
                        .LoadDataRow(Data, True)
                    Next
                    xlWorkbook.Close()
                    xlApp.Quit()
                    KillExcelProcess()
                End If
            End If
        Else
            MessageBox.Show("Please Select Excel File", "Information", MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
        End If
    End With

by doing this you will have you excel data in your DataTable and then its on you where you want to save like save it in the sql server or storage area. let me know for further clarification.
