Adding page numbers to pdf through VBA and Acrobat IAC

I am trying to do the following thing from Excel vba:

1. Export certain worksheets to pdf
2. Take an existing pdf document and insert it in the newly generated pdf at a specific place (not necessarily at the end or at the beginning)
3. Number the pages of the merged pdf, omitting two title pages

I already figured out the first step. For the second and third step, I have Adobe Acrobat XI Pro at my disposal. Since I want to do this in one go from vba, I have downloaded the Acrobat SDK. From some quick Googling, I think I should be able to figure out the second step now, using the IAC, but the third step (oddly) seems the most difficult. Any suggestions would be welcome.

Best, NiH

In the meantime, I found a solution for adding page numbers. For anyone who might be interested, here's an example of how it can be done:

Sub addPageNumbers()

    Dim acroApp As Acrobat.acroApp
    Dim myDocument As Acrobat.AcroPDDoc
    Dim jso As Object

    Dim strPath As String
    Dim strFileName As String
    Dim intPages As Integer
    Dim i As Integer

    Set acroApp = CreateObject("AcroExch.App")
    Set myDocument = CreateObject("AcroExch.PDDOc")

    strPath = "C:\"
    strFileName = "myDoc.pdf"

    'Open file and load JSObject
    Set myDocument = CreateObject("AcroExch.PDDOc")
    myDocument.Open (strPath & strFileName)
    Set jso = myDocument.GetJSObject

    ' get number of pages
    intPages = myDocument.GetNumPages

    'Write page numbers to all pages
    For i = 1 To intPages
        jso.addWatermarkFromText _
            cText:=Str(i) & "  ", _
            nTextAlign:=1, _
            nHorizAlign:=2, _
            nVertAlign:=4, _
            nStart:=i - 1, _
            nEnd:=i - 1
    Next i

    'Save document
    Call myDocument.Save(1, strPath & strFileName)

    'Clean up
    Set jso = Nothing
    Call acroApp.CloseAllDocs
    Set myDocument = Nothing
    Call acroApp.Exit
    Set acroApp = Nothing

End Sub

Keep in mind that you need to have Acrobat (not only the reader) installed on your computer, and the reference to Acrobat has to be enabled in the vba editor.

I did not add error handling; obviously you should.
