How To: Combine PDFs Using InsertPages



Issue
How do I combine multiple PDFs into one PDF using Visual Basic?
Solution
This record contains VisualBasic code to demonstrate AcroExch.PDDoc InsertPages.

As far as InsertPages is concerned, the tricky part is to remember that the page number you will be inserting after is -1; in other words, you want to insert these pages before page 0, which is the first page of the document.

Private Sub Command1_Click()
Dim b As Boolean

Dim AcroPDDoc As CAcroPDDoc
Dim PDDoc As CAcroPDDoc

Set AcroPDDoc = CreateObject("AcroExch.PDDoc")
Set PDDoc = CreateObject("AcroExch.PDDoc")

b = PDDoc.Open("c:\testinsertpages.pdf")
b = AcroPDDoc.Open("c:\Tips.pdf")
b = AcroPDDoc.InsertPages(0, PDDoc, 0, 1, False)
b = AcroPDDoc.Save(1, "c:\Tips.pdf")

End Sub
