Answer 1

Finally solved :)

Private Function useSomeExcel(ByVal Excelfilename As String) 
  Dim objExcel As Excel.Application
  Dim objWorkBook As Excel.Workbook
  Dim objWorkSheets As Excel.Worksheet

  Dim datestart As Date = Date.Now
  objExcel = CreateObject("Excel.Application") 'This opens...  
  objWorkBook = objExcel.Workbooks.Open(Excelfilename) ' ... excel process
  Dim dateEnd As Date = Date.Now
  End_Excel_App(datestart, dateEnd) ' This closes excel proces
End Function

use this method

  Private Sub End_Excel_App(datestart As Date, dateEnd As Date)
    Dim xlp() As Process = Process.GetProcessesByName("EXCEL")
    For Each Process As Process In xlp
     If Process.StartTime >= datestart And Process.StartTime <= dateEnd Then
       Process.Kill()
       Exit For
     End If
    Next
  End Sub

This method closes especific process opened.

Answer 2

Try System.Runtime.InteropServices.Marshal.FinalReleaseComObject, that should help... also you should call xlWorkBook.Close() and xlapp.quit, if I recall correctly. First call them and then set them to nothing.
