Including Revision in BatchPDF Script

I'd basically like to include something like this, but not exactly sure how.  Basically what i want to do is take the script at the bottom and make it so that when it saves the PDF it actually saves it as FileName + Revision.pdf (or if the revision is - or blank) just the filename.

Dim swCustPrpMgr As SolidWorks.Interop.sldworks.CustomPropertyManager

swCustPrpMgr = swModel.Extension.CustomPropertyManager(

"")

Dim rev As String

swCustPrpMgr.Get3(

"Revision", False, "", rev)

If rev = "-" Then

rev =

""

Else

rev =

"_" + rev

End If

into the following BATCH PDF file:

Public Sub main()

Dim Drawing As ModelDoc2 = Nothing

Dim longstatus As Integer = 0

Dim longwarnings As Integer = 0

Dim FileToOpen As String

Dim SourcePath As String

'show a folder browser dialog to the user

Dim FolderDia As New FolderBrowserDialog

FolderDia.Description =

"Select a folder to process"

Dim diaRes As DialogResult = FolderDia.ShowDialog

'if the user clicks anything other than OK, exit

If Not diaRes = DialogResult.OK Then

Exit Sub

End If

'source path is the folder the user selected

SourcePath = FolderDia.SelectedPath

'use DirectoryInfo to get all drawing files in the selected folder

Dim SourceDir As New DirectoryInfo(SourcePath)

Dim sourceFiles() As FileInfo

sourceFiles = SourceDir.GetFiles(

"*.SLDDRW")

'loop through all drawing files in the sourceFiles array

For Each DrawingFile As FileInfo In sourceFiles

FileToOpen = DrawingFile.FullName

'simple SolidWorks call to open a file

Drawing = swApp.OpenDoc(FileToOpen, swDocumentTypes_e.swDocDRAWING)

Dim SaveAsPDFName As String

SafeAsPDFName = FileToOpen + rev

'change the file extension to PDF

Dim PDFName As String

PDFName = IO.Path.ChangeExtension(SaveAsPDFName,

".PDF")

'create the PDF and close the drawing

Dim ret As Boolean = Drawing.Extension.SaveAs(PDFName, 0, 0, Nothing, longstatus, longwarnings)

swApp.CloseDoc(FileToOpen)

Next

End Sub
