Apple Script and Visual Basic

I have to merge a high number of .doc files and print the result to PDF. At the same time, I need to keep different datas of the .doc files to create bookmarks for the PDF files : for example, one of my .doc’s name is 890331.doc and it contains 36 pages : my bookmark will be “Friday, 29 March 1989 - 36 p.” in the PDF file.
Is there another solution to get the number of pages of each .doc. Presently, I have not succeeded in getting back it with Visual Basic and found another means, see below,(not very smart technically speaking !..)
Could someone tell me why I can’t get NbdePages with :
do Visual Basic “NbdePages = ActiveDocument.ComputeStatistics(Statistic:=wdStatisticPages)”
And, more generally, how to get a variable from Visual Basic ?
(NB : I must merge the .doc files before printing to PDF because I haven’t succeeded in changing the page setup with do Visual Basic " With ActiveDocument.PageSetup …" ) : I can’t set the “Landscape” orientation in the PDFwriter.

Thank you in advance for all your help,

Here is the handler that “works” but is not technically so smart :


on getnbpage(Filename)
	tell application "Microsoft Word"
		activate
		open (Filename)
		do Visual Basic "	Selection.WholeStory"
		copy
	---NbdePages = ActiveDocument.ComputeStatistics(Statistic:=wdStatisticPages)
		do Visual Basic "	If ActiveWindow.View.SplitSpecial = wdPaneNone Then
		ActiveWindow.ActivePane.View.Type = wdPageView
	Else
		ActiveWindow.View.Type = wdPageView
	End If"
		do Visual Basic "	Selection.EndKey Unit:=wdStory"
		set contents of selection to "MesPages"
		do Visual Basic "	Selection.Fields.Add Range:=Selection.Range, Type:=wdFieldEmpty, Text:= _
		"NUMPAGES ", PreserveFormatting:=True"
		set toto to (get last word)
		close document Filename saving no
	end tell
	return toto as string
end getnbpage

I do not have a solution for your questions or problems, though I do have some info that may help out a little.
