我如何使用 VBA 代码合并多个 pdf 文件 [英] how i can merge multi pdfs files by using VBA code

问题描述

我有一个包含多个 pdf 文件路径的表...现在我需要一个 VBA 代码来将所有这些文件合并为一个 pdf 文件.注意:-要合并的pdfs文件的数量会不时变化.

I have a table that contains a paths of multi pdfs file...now I need a VBA code to merge all these files to a single pdf file. Notice:-the number of pdfs files to be merged varies from time to time.

Sub Combine_PDFs_Demo()
Dim i As Integer 'counter for records
Dim x As Integer
Dim strNPDF As String
Dim bSuccess As Boolean
Dim DB As Database
Dim RS As Recordset
Set DB = CurrentDb
Set RS = DB.OpenRecordset("SELECT[paths] from scantemp ")
strNPDF = CurrentProject.Path & "\request_pic\" & (request_no) & ".pdf"
RS.MoveLast
DB.Recordsets.Refresh
i = RS.RecordCount
RS.MoveFirst
Dim strPDFs() As String
ReDim strPDFs(0 To i)
strPDFs(0) = RS![paths]
RS.MoveNext
For i = 1 To i - 1
strPDFs(i) = RS![paths]
bSuccess = MergePDFs(strPDFs, strNPDF)
Next i
If bSuccess = False Then MsgBox "Failed to combine all PDFs", vbCritical, "Failed to Merge PDFs"
DoCmd.SetWarnings False
DoCmd.RunSQL "delete from scantemp" 'delete all paths from table scantemp after converted it to pdf
DoCmd.SetWarnings True
  RS.Close
    Set RS = Nothing`enter code here`

public Function MergePDFs(arrFiles() As String, strSaveAs As String) As Boolean
Dim objCAcroPDDocDestination As Acrobat.CAcroPDDoc
Dim objCAcroPDDocSource As Acrobat.CAcroPDDoc
Dim i As Integer
Dim iFailed As Integer

On Error GoTo NoAcrobat:
'Initialize the Acrobat objects
Set objCAcroPDDocDestination = CreateObject("AcroExch.PDDoc")
Set objCAcroPDDocSource = CreateObject("AcroExch.PDDoc")
 'Open Destination, all other documents will be added to this and saved with
'a new filename
objCAcroPDDocDestination.Open (arrFiles(LBound(arrFiles))) 'open the first file
 'Open each subsequent PDF that you want to add to the original
  'Open the source document that will be added to the destination
    For i = LBound(arrFiles) + 1 To UBound(arrFiles)
        objCAcroPDDocSource.Open (arrFiles(i))
        If objCAcroPDDocDestination.InsertPages(objCAcroPDDocDestination.GetNumPages - 1, objCAcroPDDocSource, 0, objCAcroPDDocSource.GetNumPages, 0) Then
          MergePDFs = True
        Else
          'failed to merge one of the PDFs
          iFailed = iFailed + 1
        End If
        objCAcroPDDocSource.Close
    Next i
objCAcroPDDocDestination.save 1, strSaveAs 'Save it as a new name
objCAcroPDDocDestination.Close
Set objCAcroPDDocSource = Nothing
Set objCAcroPDDocDestination = Nothing

NoAcrobat:
If iFailed <> 0 Then
    MergePDFs = False
End If
On Error GoTo 0
End Function
