Acrobat 无法读取用 Excel VBA 编写的 .FDF

Question

我在 FDF 中导出了一个带有表单字段的 PDF，并编写了一个子程序来逐字输出另一个 FDF，其中包含表单字段值的单元格值。如果我在文本编辑器中编辑 FDF 并更改值，Acrobat 可以很好地读取文件，但带有 VBA 的文件输出会引发错误：

Adobe could not open whatever.fdf because it is either not a supported file type or because the file has been damaged

我试过两种不同类型的换行符，我试过一个类似的 xfdf 格式的 sub，它略有不同但结果相同。

Sub something()

Dim sht As Worksheet
Set sht = Sheets("owssvr")

Dim lastrow As Integer
lastrow = sht.Cells(sht.Rows.Count, "A").End(xlUp).Row

Dim fso As Object
Set fso = CreateObject("Scripting.FileSystemObject")
Dim Fileout As Object

Dim x As Integer
For x = 2 To lastrow
    Set Fileout = fso.CreateTextFile("C:\Users\blabla\" & x & ".fdf", True, True)
                Fileout.Write "%FDF-1.2" & vbCrLf & _
                "%âãÏÓ" & vbCrLf & _
                "1 0 obj" & vbCrLf & _
                "<</FDF<</F(MyDocument.pdf)/Fields[<</T(Adobe Form Field)/V(" & sht.Range("U" & x) & ")>>]/ID[<4ED54800AC4A3D41ABE4F4C7B12A3D23><609E705B7532334B8F914CFF4C09F2A0>]/UF(MyDocument.pdf)>>/Type/Catalog>>" & vbCrLf & _
                "endobj" & vbCrLf & _
                "trailer" & vbCrLf & _
                "<</Root 1 0 R>>" & vbCrLf & _
                "%%EOF" & vbCrLf
Fileout.Close

Next x

End Sub

Answer 1

简单地省略行：“%âãÏÓ”& vbCrLf & _”。/ID 和 /UF 键并不是真正需要的。

像这样的东西应该可以工作：

Fileout.Write "%FDF-1.2" & vbCrLf & _
            "1 0 obj<</FDF<<" & vbCrLf & _
            "/F(MyDocument.pdf)" & vbCrLf & _
            "/Fields" & vbCrLf & _
            "[<</T(Adobe Form Field)/V(xyValue)>>]" & vbCrLf & _            
            ">>>>" & vbCrLf & _
            "endobj" & vbCrLf & _
            "trailer" & vbCrLf & _
            "<</Root 1 0 R>>" & vbCrLf & _
            "%%EOF" & vbCrLf

Answer 2

虽然我很想打开它，希望有人能弄清楚为什么 VBA 搞砸了 unicode，但我的问题可以在根本不调用 fso 的情况下解决，只需使用 FreeFile 和字符串替换原始 FDF

Sub blabla()

Dim objAcroApp As Acrobat.AcroApp
Dim objAcroAVDoc As Acrobat.AcroAVDoc
Dim objAcroPDDoc As Acrobat.AcroPDDoc
Dim jsObj As Object
Dim boResult As Boolean
Dim oldPDF As String
Dim NewFilePath As String

    Dim sTemp As String
    Dim iFileNum As Integer
    Dim oldFDF As String
    Dim i As Integer
    Dim lastRow As Integer
    Dim sht As Worksheet
    Set sht = Sheets("owssvr")

    With sht
        lastRow = .Range("A" & .Rows.Count).End(xlUp).Row
    End With

    For i = 2 To lastRow

    oldPDF = "\mydoc.pdf"
    oldFDF = "\mydoc_data.fdf"
    newPDF = "\" & i & ".pdf"

    iFileNum = FreeFile
    Open oldFDF For Input As iFileNum

    Do Until EOF(iFileNum)
    Line Input #iFileNum, sBuf
    sTemp = sTemp & vbCrLf
    Loop
    Close iFileNum

    sTemp = Replace(sTemp, "<</T(some form field)/V( )>>", "<</T(some form field)/V(" & sht.Range("E" & i) & ")>>")

    iFileNum = FreeFile
    oldFDF = "\" & i & ".fdf"
    Open oldFDF For Output As iFileNum

    Print #iFileNum, sTemp

    Close iFileNum

            Set objAcroApp = CreateObject("AcroExch.App")
            Set objAcroAVDoc = CreateObject("AcroExch.AVDoc")
            boResult = objAcroAVDoc.Open(oldPDF, "")
            Set objAcroPDDoc = objAcroAVDoc.GetPDDoc
            Set jsObj = objAcroPDDoc.GetJSObject
            jsObj.ImportAnFDF oldFDF
            jsObj.SaveAs newPDF
            boResult = objAcroAVDoc.Close(True)
            boResult = objAcroApp.Exit

Next i


End Sub

您会在 Acrobat IAC 文档中找到它。这是一个快速的 vbs(vba) 示例。你只需要其中的两行：jso.getField 和 f.value =...祝你好运。

  '//-> Set a value for a form field via JSO
  '//-> Settings
FileNm = "d:\TestInput.pdf"
FieldNm= "Input1"
FieldValue= "50"
  '//-> let's start
Set App = CreateObject("Acroexch.app")
app.show
Set AVDoc = CreateObject("AcroExch.AVDoc")
    '//-> open the file and put the value in
If AVDoc.Open(FileNM,"") Then
    Set PDDoc = AVDoc.GetPDDoc()
    Set jso = PDDoc.GetJSObject
  '//-> Get the field and put a value in
    set f = jso.getField(FieldNm)
    f.value = FieldValue
end if
