split pdf based on the text using vba acrobat api - vba

Question

I am trying to split pdf, based on the pages where it finds ".pdf" however when I try to save the pdf with a dynamic string variable, it do not save the pdf but when I write hardcode file path it output the pdf. do not know what is going on here.
the following code is not finished yet I am stuck in creating new pdf with deleted pages:
Function Extract_PDF()
Dim aApp As Acrobat.CAcroApp
Dim av_Doc As Acrobat.CAcroAVDoc
Dim pdf_Doc As Acrobat.CAcroPDDoc '
Dim newPDFdoc As Acrobat.CAcroPDDoc
Dim Sel_Text As Acrobat.CAcroPDTextSelect
Dim i As Long, j As Long
Dim pageNum, Content
Dim pageContent As Acrobat.CAcroHiliteList
Dim found As Boolean
Dim foundPage As Integer
Dim PDF_Path As String
Dim pdfName As String
Dim folerPath As String
Dim FileExplorer As FileDialog
Set FileExplorer = Application.FileDialog(msoFileDialogFilePicker)
With FileExplorer
.AllowMultiSelect = False
.InitialFileName = ActiveDocument.Path
.Filters.Clear
.Filters.Add "PDF File", "*.pdf"
If .Show = -1 Then
PDF_Path = .SelectedItems.Item(1)
Else
PagesLB = "Catch me Next Time ;)"
PDF_Path = ""
Exit Function
End If
End With
Set aApp = CreateObject("AcroExch.App")
Set av_Doc = CreateObject("AcroExch.AVDoc")
If av_Doc.Open(PDF_Path, vbNull) <> True Then Exit Function
While av_Doc Is Nothing
Set av_Doc = aApp.GetActiveDoc
Wend
av_Doc.BringToFront
aApp.Show
Set pdf_Doc = av_Doc.GetPDDoc
For i = pdf_Doc.GetNumPages - 1 To 0 Step -1
Set pageNum = pdf_Doc.AcquirePage(i)
Set pageContent = CreateObject("AcroExch.HiliteList")
If pageContent.Add(0, 9000) <> True Then Exit Function
Set Sel_Text = pageNum.CreatePageHilite(pageContent)
Content = ""
found = False
For j = 0 To Sel_Text.GetNumText - 1
Content = Content & Sel_Text.GetText(j)
If InStr(1, Content, ".pdf") > 0 Then
found = True
foundPage = i
pdfName = Content
Exit For
End If
Next j
If found Then
PDF_Path = Left(PDF_Path, InStrRev(PDF_Path, "\")) & ValidWBName(pdfName)
Set newPDFdoc = CreateObject("AcroExch.PDDoc")
Set newPDFdoc = av_Doc.GetPDDoc
If newPDFdoc.DeletePages(0, i - 1) = False Then
Debug.Print "Failed"
Else
Debug.Print "done"
End If
If newPDFdoc.Save(PDSaveFull, PDF_Path) = False Then
Debug.Print "Failed to save pdf "
Else
Debug.Print "Saved"
End If
newPDFdoc.Close
End If
Next i
av_Doc.Close False
aApp.Exit
Set av_Doc = Nothing
Set pdf_Doc = Nothing
Set aApp = Nothing
End Function
ValidWBName:
Function ValidWBName(agr As String) As String
Dim RegEx As Object
Set RegEx = CreateObject("VBScript.RegExp")
With RegEx
.Pattern = "[\\/:\*\?""<>\|]"
.Global = True
ValidWBName = .Replace(agr, "")
End With
End Function
in above function when it finds the word pdf it try to create a new instance of pdf and remove previous pages.
If found Then
PDF_Path = Left(PDF_Path, InStrRev(PDF_Path, "\")) & ValidWBName(pdfName)
Set newPDFdoc = CreateObject("AcroExch.PDDoc")
Set newPDFdoc = av_Doc.GetPDDoc
If newPDFdoc.DeletePages(0, i - 1) = False Then
Debug.Print "Failed"
Else
Debug.Print "done"
End If
If newPDFdoc.Save(PDSaveFull, PDF_Path) = False Then
Debug.Print "Failed to save pdf "
Else
Debug.Print "Saved"
End If
newPDFdoc.Close
End If
this line "Failed to save pdf"
If newPDFdoc.Save(PDSaveFull, PDF_Path) = False Then
but when I write hardcode path it create the pdf
If newPDFdoc.Save(PDSaveFull, "C:\Users\MBA\Desktop\PDF Project 2\Murdoch_Michael__Hilary_PIA_19.pdf") = False Then

Answer 1

the culprit HAD to be in ValidWBName() function, which didn't handle all possible not allowed chars for a valid file name
since it came out vbCr char was one of them, you could change it as follows:
Function ValidWBName(agr As String) As String
Dim RegEx As Object
Set RegEx = CreateObject("VBScript.RegExp")
With RegEx
.Pattern = "[\\/:\*\?""<>\|" & Chr(13) & "]" ' <-- added vbCr
.Global = True
ValidWBName = .Replace(agr, "")
End With
End Function
