[英]The code to merge adjacent cells using VBA isn't working anymore and I can't seem to find the problem
[英]how i can merge multi pdfs files by using VBA code
我有一個包含多個pdfs文件路徑的表...現在我需要一個VBA代碼將所有這些文件合並為一個pdf文件。 注意:-要合並的pdf文件的數量有時會有所不同。
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
這使用PDF或PS文件列表來創建一個PDF。 抱歉,它在VB.net中,我真的沒有時間進行轉換。 但是,它說明了您可以嘗試的概念。 基本上,您將選項和文件名寫入文本文件,然后將該文件用作Ghostscript的參數。
Private Shared Sub ConvertToPDF(ByVal PSPathFileList As List(Of String), _
ByVal PDFPathName As String, _
ByVal WaitForExit As Boolean, ByVal DeletePS As Boolean)
'check that all files exist
PSPathFileList.ForEach(AddressOf CheckFiles)
'check old pdf file
If IO.File.Exists(PDFPathName) Then
Throw New ApplicationException( _
"PDF cannot be created. File already exists: " & PDFPathName)
End If
'convert engine
Dim myProcInfo As New ProcessStartInfo
myProcInfo.FileName = DanBSolutionsLocation & "Misc\GhostScript\GSWIN32C.EXE"
Debug.Print(myProcInfo.FileName)
'write file names to text file as the list can be very long
Dim tempPath As String = IO.Path.GetDirectoryName(PSPathFileList.Item(0))
Dim fiName2 As String = tempPath & IO.Path.GetFileNameWithoutExtension(PDFPathName) & ".txt"
Dim ft As New StreamWriter(fiName2)
ft.WriteLine("-sDEVICE=pdfwrite -q -dSAFER -dNOPAUSE -sOUTPUTFILE=""" & PDFPathName & """ -dBATCH ")
For i As Long = 0 To PSPathFileList.Count - 1
ft.WriteLine(Chr(34) & PSPathFileList.Item(i) & Chr(34))
Next
ft.Close()
'set args to text file
myProcInfo.Arguments = """@" & fiName2 & """"
'set up for output and errors
myProcInfo.UseShellExecute = False
myProcInfo.RedirectStandardOutput = True
myProcInfo.RedirectStandardError = True
Debug.Print(myProcInfo.Arguments)
'do the conversion
Dim myProc As Process = Process.Start(myProcInfo)
Debug.Print(myProc.StandardOutput.ReadToEnd)
Debug.Print(myProc.StandardError.ReadToEnd)
If WaitForExit Then
'wait for finish; (no more than 60 seconds)
myProc.WaitForExit(60000)
'delete PS
If DeletePS Then
PSPathFileList.ForEach(AddressOf DeleteFiles)
End If
End If
End Sub
這是單個PS到PDF的VBA代碼。 因此,希望在上面的VB.net和下面的VB.net之間可以找到有用的東西。
Private Sub printToPdfDemo()
'verify printer setup
'be sure to install the PsPrinterInstall module
Call PSPrinterSetup
Dim svPsFileName As String
Dim svPDFName As String
'define names
svPsFileName = "C:\Temp\Input 1.ps"
svPDFName = "C:\Temp\Output 1.PDF"
'save current printer
Dim PrinterInUse As String
PrinterInUse = Application.ActivePrinter
'print to PS
'If Fso.FileExists(svPsFileName) Then Call Fso.DeleteFile(svPsFileName)
Worksheets(1).PrintOut ActivePrinter:=PSPrinterName, PrintToFile:=True, _
PrToFileName:=svPsFileName
'revert to saved printer name
Application.ActivePrinter = PrinterInUse
'convert
Call ConvertToPDF(svPsFileName, svPDFName)
End Sub
Sub ConvertToPDF(ByVal svPsFileName As String, ByVal svPDFName As String)
Dim fso As New FileSystemObject
'Dim Fso: Set Fso = CreateObject("Scripting.FileSystemObject")
Dim folGS As Folder
Dim lcCmd As String
'check inputs
If svPsFileName = "" Or svPDFName = "" Then
Call MsgBox("PS file name or PDF file name is blank in ""ConvertToPDF"" macro", vbExclamation, "Error! Missing Inputs")
Exit Sub
End If
'check file
If Not fso.FileExists(svPsFileName) Then
Call MsgBox(svPsFileName & " file is not found", vbExclamation, "Error! Missing File")
Exit Sub
End If
'check variable
If DanBSolutionsLocation = "" Then DanBSolutionsLocation = GetDanBSolutionsLocation
'delete old file
If fso.FileExists(svPDFName) Then Call fso.DeleteFile(svPDFName)
'get files
Set folGS = fso.GetFolder(DanBSolutionsLocation & "Misc\GhostScript\") 'S:\DanB Solutions\Misc\GhostScript\GSWIN32C.EXE
'GS command
lcCmd = folGS.ShortPath & "\GSWIN32C.EXE " & _
"-q -dNOPAUSE -I" & folGS.ShortPath & "\lib;./fonts " & _
"-sFONTPATH=./fonts -sFONTMAP=" & folGS.ShortPath & "\lib\FONTMAP.GS " & _
"-sDEVICE=pdfwrite -sOUTPUTFILE=" & """" & svPDFName & """" _
& " -dBATCH " & """" & svPsFileName & """"
'convert
Debug.Print lcCmd
Call ShellWait(lcCmd)
'delete PS
If fso.FileExists(svPDFName) Then fso.DeleteFile (svPsFileName)
End Sub
