adding page numbers when programatically merging PDFs with acrobat - vba

Question

Hi the code below merges pdfs using adobe acrobat. It works but I am looking to add page numbers to the document so that if I merge 2 documents that are 4 pages each the page numbers go from 1 to 8. How can that be done?
Here is the code:

Sub MergePDFs()

Const MyPath = "C:\mypath" '"C:\Temp" ' Path where PDF files are stored
Const MyFiles = "file1.pdf,file2.pdf" ' List of PDFs to ne merged
Const DestFile = "MergedFile.pdf" ' The name of the merged file
' <-- End of settings
Dim a As Variant, i As Long, n As Long, ni As Long, p As String
Dim AcroApp As New Acrobat.AcroApp, PartDocs() As Acrobat.CAcroPDDoc
If Right(MyPath, 1) = "\" Then p = MyPath Else p = MyPath & "\"
a = Split(MyFiles, ",")
ReDim PartDocs(0 To UBound(a))
On Error GoTo exit_
If Len(Dir(p & DestFile)) Then Kill p & DestFile
For i = 0 To UBound(a)
' Check PDF file presence
If Dir(p & Trim(a(i))) = "" Then
MsgBox "File not found" & vbLf & p & a(i), vbExclamation, "Canceled"
Exit For
End If
' Open PDF document
Set PartDocs(i) = CreateObject("AcroExch.PDDoc")
PartDocs(i).Open p & Trim(a(i))
If i Then
' Merge PDF to PartDocs(0) document
ni = PartDocs(i).GetNumPages()
If Not PartDocs(0).InsertPages(n - 1, PartDocs(i), 0, ni, True) Then
MsgBox "Cannot insert pages of" & vbLf & p & a(i), vbExclamation, "Canceled"
End If
' Calc the number of pages in the merged document
n = n + ni
' Release the memory
PartDocs(i).Close
Set PartDocs(i) = Nothing
Else
' Calc the number of pages in PartDocs(0) document
n = PartDocs(0).GetNumPages()
End If
Next
If i > UBound(a) Then
' Save the merged document to DestFile
If Not PartDocs(0).Save(PDSaveFull, p & DestFile) Then

Set PartDocs(0) = Nothing
' Quit Acrobat application
AcroApp.Exit
Set AcroApp = Nothing
End Sub

attached a stand-alone VBS/VBA script, which add the page number as footer to your pdf. You may took out the parts you need and write into your script just before you save the pdf or execute it afterwards.
Full Script:
File = "D:\Test.pdf"
Set App = CreateObject("Acroexch.app") '//start acrobat
app.show '//show Acrobat or comment out for hidden mode
Set AVDoc = CreateObject("AcroExch.AVDoc")
Set AForm = CreateObject("AFormAut.App") '//get AFormAPI to execute js later
If AVDoc.Open(File,"") Then
'//write JS-Code on a variable
Ex = " // set Date, filename and PageNo as footer "&vbLF _
& " var Box2Width = 50 "&vbLF _
& " for (var p = 0; p < this.numPages; p++) "&vbLF _
& " { "&vbLF _
& " var aRect = this.getPageBox(""Crop"",p); "&vbLF _
& " var TotWidth = aRect[2] - aRect[0] "&vbLF _
& " { var bStart=(TotWidth/2)-(Box2Width/2) "&vbLF _
& " var bEnd=((TotWidth/2)+(Box2Width/2)) "&vbLF _
& " var fp = this.addField(String(""xftPage""+p+1), ""text"", p, [bStart,30,bEnd,15]); "&vbLF _
& " fp.value = ""Page: "" + String(p+1)+ ""/"" + this.numPages; "&vbLF _
& " fp.textSize=6; fp.readonly = true; "&vbLF _
& " fp.alignment=""center""; "&vbLF _
& " } "&vbLF _
& " } "
'//Execute JS-Code
AForm.Fields.ExecuteThisJavaScript Ex
msgBox("Done")
end if
Set AVDoc = Nothing
Set APP = Nothing
The parts you really need if you only want to take over in your script:
Set AForm = CreateObject("AFormAut.App")
Ex = " // set Date, filename and PageNo as footer "&vbLF _
& " .....
& " .....
& " } "
'//Execute JS-Code
AForm.Fields.ExecuteThisJavaScript Ex
This also demonstrates how you can use/execute AcroJs via VBS/VBA without translating to JSO (Java Script Object).
Good luck, Reinhard
