Vb.net Interop with Word 2010 printing Avery Labels

[waddellg]

Hi
I had written an app in VB.net that took addresses from a database put them into a csv file then took the csv file data and performed a mail merge in Word to allow the user to print them out on to an Avery L7163 label sheet.

The app was working fine until our company upgraded from Windows XP with office 2000 to Windows 7 with Office 2010.

Instead of getting the labels populated with the address data there are what appear to be form fields printed e.g. <<Address 1>>. Also they are not appearing in the order they should be but rather as a random mis-mash here is the code:

Sub PrintAvery(byref Printer as string, byref Tray as integer, byref CSVFile as String)
	Dim oWord As Object = CreateObject("Word.Application")
	Dim oDoc As Object  = oWord.Documents.add
	With oWord
		.visible = False
		.DisplayAlerts = wdAlertsNone
		.MailingLabel.DefaultPrintBarCode = False
	End With
	'suspect this part is not working as fields not coming in correct order
	With oDoc.MailMerge.Fields
		Dim MySelection = oWord.Selection.Range
                .Add(MySelection, "Address1")
                oWord.Selection.TypeParagraph()
                .Add(MySelection, "Address2")
                oWord.Selection.TypeParagraph()
                .Add(MySelection, "Address3")
                oWord.Selection.TypeParagraph()
                .Add(MySelection, "Address4")
                oWord.Selection.TypeParagraph()
                .Add(MySelection, "Address5")
                oWord.Selection.TypeParagraph()
                .Add(MySelection, "Address6")
                oWord.Selection.TypeParagraph()
                .Add(MySelection, "Address7")
                oWord.Selection.TypeParagraph()
                .Add(MySelection, "Country")
                oWord.Selection.TypeParagraph()
        End With
        Dim myContent = oDoc.Content
        oWord.NormalTemplate.AutoTextEntries.Add("MyLabelLayout", myContent)
        myContent.Delete() 'we no longer need this as we have added it as autotext or have we?	
	Dim ActiveDoc = oWord.ActiveDocument
 	With ActiveDoc.MailMerge
        	.MainDocumentType = 1
                .OpenDataSource(Name:=CSVFile, ConfirmConversions:=False, ReadOnly:=False, LinkToSource:=True, AddToRecentFiles:=False, PasswordDocument:="", PasswordTemplate:="", _
                                WritePasswordDocument:="", WritePasswordTemplate:="", Revert:=False, Format:=0, Connection:="", SQLStatement:="", SQLStatement1:="")
        End With
	Dim oDoc2 As Object = oWord.MailingLabel.CreateNewDocument(Name:="L7163", Address:="", AutoText:="MyLabelLayout", LaserTray:=Tray) 	
	With ActiveDoc.MailMerge
                .DataSource.QueryString = "SELECT * FROM " & CSVFile
                .Destination = 0
                .MailAsAttachment = False
                .MailAddressFieldName = ""
                .MailSubject = ""
                .SuppressBlankLines = True
                With .DataSource
                    .FirstRecord = 1
                    .LastRecord = -16
                End With
                .Execute(Pause:=True) 'data not coming in
       End With
        If InStr(oWord.ActivePrinter, Printer) = 0 Then
            With oWord.Dialogs.Item(wdDialogFilePrintSetup)
                .printer = Printer
                .donotsetassysdefault = True
                .Execute()
            End With
        End If
        ActiveDoc.PageSetup.FirstPageTray = MainTray
        ActiveDoc.PageSetup.OtherPagesTray = MainTray
        ActiveDoc.PrintOut(Range:=wdPrintAllDocument, Item:=wdPrintDocumentContent, Copies:=1)
        'wait for print out
        System.Threading.Thread.Sleep(1000)

        For Each Doc As Object In oWord.Documents
            Doc.close(False)
        Next
        oWord.quit()	
End Sub

I suspect either the part where I store the field layout as autotext is not working

 Dim myContent = oDoc.Content
 oWord.NormalTemplate.AutoTextEntries.Add("MyLabelLayout", myContent)

Or the part where I set it as the Autotext of the new label document

Dim oDoc2 As Object = oWord.MailingLabel.CreateNewDocument(Name:="L7163", Address:="", AutoText:="MyLabelLayout", LaserTray:=Tray)

And the Merge doesn't seam to pick up the data form the csv file even though the file exists and is populated.

Any ideas as to what's gone wrong or alternative methods?

Thanks in Advance G
