Classic ASP: How to access HeadersFooters Class.LinkToPrevious Method?

I am practically done with my application and all I’m missing right now
is being able to unlink previous headers/footers so I can customize
each header/footer for each sectioned new page. I need to have total
control of the headers and footers. Please tell me that I can access
this class through Classic ASP? Thank you.

There are two overloads for this method in the API:

  • HeadersFooters.LinkToPrevious Method (Boolean),
  • HeadersFooters.LinkToPrevious Method (HeaderFooterType, Boolean).

Have you tried to access them LinkToPrevious and LinkToPrevious_2?

Look like there’s hope :slight_smile: But I’m still not sure how to access the LinkToPrevious method.



This is a short
code which tests the LinkToPrevious method, hopefully someone
can spot the error:



----BEGIN----


'Load a document

Dim Word, Doc

Set Word = CreateObject(“Aspose.Word.Word”)

Set Doc = Word.Open(“C:\Inetpub\wwwroot\template.doc”)



'Create a DocumentBuilder

Dim Builder

Set Builder = CreateObject(“Aspose.Word.DocumentBuilder”)



Builder.Document = Doc



'MAIN LOGIC

Builder.Writeln “Start Aspose.Word programming here”

Builder.InsertBreak 5 '–BreakType.SectionBreakNewPage

Builder.Writeln “The cursor is in the new page”

Builder.Writeln “Lets try to unlink the current header/footer”

Builder.HeadersFooters.LinkToPrevious = 0 ’ – ERROR



–END–



I tried changing the – ERROR line to various lines such as:

Builder.HeadersFooters.LinkToPrevious = 0

Builder.HeadersFooters.LinkToPrevious 0

Builder.LinkToPrevious = 0

Builder.LinkToPrevious 0

Doc.HeadersFooters.LinkToPrevious = 0

Doc.HeadersFooters.LinkToPrevious 0



But it says the object doesn’t support HeadersFooters or LinkToPrevious.

Ok, now I've got what your problem is. HeadersFooters is actually a document section property, not of the document itself. So you need to call it with Doc.Sections(0).HeadersFooters.

I tried changing it to:



Doc.Sections(1).HeadersFooters.LinkToPrevious 0

Doc.Sections(1).HeadersFooters.LinkToPrevious = 0

Doc.Sections(1).HeadersFooters.LinkToPrevious False

Doc.Sections(1).HeadersFooters.LinkToPrevious = False



But all four lines still generates an error saying that I’m using Sections improperly.



The good news is that at least Doc.Sections object works and that I’m
just using it improperly.



So what can I do to fix the code?

Sections is a 0-based array. Which means that if you want to address the first section you need to refer it as Doc.Sections(0). Use Doc.Sections.Count to check how many sections are actually in the document. Maybe you are just trying to address section that does not exist yet.

Doc.Sections.Count returned the value 3 so I guess I’m able to access
Doc.Sections(0-2). I tried all numbers between:



Doc.Sections(0 -
2).HeadersFooters.LinkToPrevious = 0

Doc.Sections(0 -
2).HeadersFooters.LinkToPrevious 0

Doc.Sections(0 -
2).HeadersFooters.LinkToPrevious False

Doc.Sections(0 -
2).HeadersFooters.LinkToPrevious = False


Doc.Sections(0 -
2).HeadersFooters.LinkToPrevious_1 = 0

Doc.Sections(0 -
2).HeadersFooters.LinkToPrevious_1 0


Doc.Sections(0 -
2).HeadersFooters.LinkToPrevious_2 = 0

Doc.Sections(0 -
2).HeadersFooters.LinkToPrevious_2 0


but still no success. The error still says I'm using Sections improperly.

I have also tried:



Doc.HeaderFooter(1).IsLinkedToPrevious = 0

Doc.HeaderFooter(1).IsLinkedToPrevious 0



Doc.HeadersFooters(1).LinkToPrevious = 0

Doc.HeadersFooters(1).LinkToPrevious 0




Still no luck.

LinkToPrevious is a method so I guess you need to refer it as

doc.Sections(0).HeadersFooters.LinkToPrevious(True)

doc.Sections(0).HeadersFooters.LinkToPrevious(True)

Stilll doesn't work. Same improper usage of "Sections" error.


In the wiki it says

Currently there are 4 publicly creatable COM objects. Their ProgIDs are:

* "Aspose.Words.Word"
* "Aspose.Words.Document"
* "Aspose.Words.DocumentBuilder"
* "Aspose.Words.License"

I looked under Aspose.Words.Document members and I can find the Sections Public Instance Properties. If I look at Sections Members I can't find a HeadersFooters Method but I did find a Count Property which explains why I could get a result from the section count I did earlier.

Since HeadersFooters is not a Public Instance Method of Aspose.Words.Document or Sections, is it to my dismay and realization that it is impossible to call the HeadersFooters.LinkToPrevious method?

To access an indexer propery from classic ASP you need to do this:

Doc.Sections.Item(0)

this code works for me:

Dim Section
Set Section = Doc.Sections.Item(0)
Section.HeadersFooters.LinkToPrevious true

If you have to deal with .NET components from a COM application, I suggest you read articles on MSDN related to .NET and COM Interop.

Yes, it works perfectly now! I suspected that I needed to Set Section = also but wasn’t sure, it would have been my last attempt. Thank you!
