RE: [PDFdev] Reading the Fields through the Automation object.

[Pete Koolish]

Quite some time ago I wrote a little utility which printed all the form field and their properties.  This was done back in the days of Acrobat 4 but I just tried it and it still runs fine with Acrobat 6, VB6 SP5, and XP Pro SP1.   Here is the code that opens up the form and iterates through the fields:   ************* BEGINNING OF CODE ******************** Dim AcroExchAVDoc As CAcroAVDoc Dim AcroExchApp As CAcroApp Dim AFormAut As AFORMAUTLib.AFormApp Dim Field As AFORMAUTLib.Field Dim Fields As AFORMAUTLib.Fields Dim OK As Boolean Dim Filename As String Dim FieldName As String   Private Sub Command1_Click()                Filename = "a.pdf"               Set AcroExchApp = CreateObject("AcroExch.App")               Set AcroExchAVDoc = CreateObject("AcroExch.AVDoc")               OK = AcroExchAVDoc.Open(App.Path & "\" & Filename, "")               Set AFormAut = CreateObject("AFormAut.App")                 Set Fields = AFormAut.Fields                    For Each Field In Fields ' Insert the code that will process each field FieldName = Field.Name    ‘ save off the field name               Next                       AcroExchAVDoc.Close (True)               Set AcroExchApp = Nothing               Set AcroExchAVDoc = Nothing End Sub **************** END OF CODE ***********************   Pete   --------------------------------------------------------------- Pete Koolish                              1036 Whitebick Drive Consultant                                 San Jose, CA  95129 The PDF Group                       408.446.3156 ---------------------------------------------------------------                                                       -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Yehuda Rosenblum Sent: Wednesday, August 06, 2003 9:50 AM To: [EMAIL PROTECTED] Subject: [PDFdev] Reading the Fields through the Automation object.     PDFdev is a service provided by PDFzone.com | http://www.pdfzone.com _____________________________________________________________   I am writing a proigram in VB (version 6.0 sp 5) that is attempting to read through the field on a PDF with the AFORMAUTLib class Fields.  The documentation says that it has a _NewEnum and therefore supports a call such as For Each Field in Fields (in fact this is the only way I can see to loop through the fields using VB 6.0).  This call worked fine in Acrobat 4.0 and 5.0.  However, when I upgraded to 6.0 I get the following Error:   Automation error Invalid access to memory location.   The object can see how many fields, but the _NewEnum property causes an Automation Error.  Does anyone know if something changed in Acrobat 6.0 that disables this functionality?  If so, is there any way to loop through the fields?   Thanks, Yehuda Rosenblum   To change your subscription: http://www.pdfzone.com/discussions/lists-pdfdev.html
