Properties

Fields As PdfAnnots (Read-only)

Returns a PdfAnnots collection of PdfAnnot objects representing individual top-level form fields.

NeedAppearances As Boolean (Read/Write)

Returns or specifies a flag controlling whether to construct appearances for all form fields in the document. False by default.

SigFlags As Long (Read/Write)

Returns or specifies signature flags. The following flag bits are defined:
Bit 1: If set, the document contains at least one signature field.
Bit 2: If set, the document contains signatures that may be invalidated if the file is saved (written) in a way that alters its previous contents (such as with the "optimize" option). Merely updating the file by appending new information to the end of the previous version is safe.

Methods

Function FindField (Name As String) As PdfAnnot

Finds and returns a top-level form field specified by Name. If no fields under this name are found, the method returns Nothing.
This method is useful for automatic form fill-out purposes.
The Form Field Finder online application enables you to determine which field names your PDF form supports.
Usage:
Set Doc = Pdf.OpenDocument("c:\1040nr.pdf")
Set Field = Doc.Form.FindField("txtFirstName")
Field.SetFieldValue "John", font

Usage:
Set Doc = Pdf.OpenDocument("c:\1040nr.pdf")
Doc.Form.RemoveXFA
' Fill in the form
