I'm trying to programmatically export a crystal report to a word document in VB.net. Here is the code that I found in help, but it isn't working. Any ideas?

code starts
************************************************** ********************
'' Declare variables and get the export options.
Dim exportOpts As New ExportOptions
Dim diskOpts As New DiskFileDestinationOptions
Dim wordFormatOpts As New ExcelFormatOptions

    exportOpts.ExportFormatType = ExportFormatType.WordForWindows
    exportOpts.FormatOptions = wordFormatOpts

'' Set the export format.
    exportOpts.ExportFormatType = ExportFormatType.WordForWindows
    exportOpts.ExportDestinationType = ExportDestinationType.DiskFile

'' Set the disk file options.
Dim newLast As String
    newLast = LastName
Dim posLast As Integer
    posLast = Len(LastName) - 1
    newLast = Microsoft.VisualBasic.Left(LastName, posLast)

    diskOpts.DiskFileName = newLast & "_" & Month(CDate(Now())) & Year(CDate(Now()))
    exportOpts.DestinationOptions = diskOpts

    UserExpenseReports2.Export()
