VB.Net Export Table to Excel

Following is my code. I want to Export my SQL table Finance into an Excel file. I am getting the error "File either does not exist or you do not have permission to access it". Whereas the file exists already. Let me tell you I already have the successful SQL session open.

' Imports

Imports System.Windows.Forms
Imports Microsoft.Office.Interop.Excel
Imports Microsoft.Office.Interop


' Class Code

        Dim objExcel As Excel.Application
        Dim objWorkBook As Excel.Workbook
        Dim objSheet As Excel.Worksheet

        Dim ExlCommand As SqlCommand
        Dim SQLCommand As String = ""
        Dim ExcelFile As String = ""

        SQLCommand = "SELECT * INTO [Excel 12.0;Database=D:\Finance\2012Jan_Mar.xlsx].[12JM] FROM FinanceTable"

        objExcel = CType(CreateObject("Excel.Application"), Microsoft.Office.Interop.Excel.Application)
        objWorkBook = CType(sobjExcel.Workbooks.Add, Microsoft.Office.Interop.Excel.Workbook)
        objSheet = CType(sobjWorkBook.Worksheets(1), Microsoft.Office.Interop.Excel.Worksheet)
        objSheet.SaveAs("D:\Finance\2012Jan_Mar.xlsx")
        objWorkBook.Close()
        sobjExcel.Quit()

        ExlCommand = New SqlCommand(SQLCommand, SQLConnection)
        ExlCommand.ExecuteNonQuery()
        objWorkBook.Save()
        objWorkBook.Close()
        sobjExcel.Quit()

Thanks.
