Good morning/evening. I am trying to use the new PB2022R2 PDF Builder feature to add page numbers and a table of contents to a new PDF document that I generate. The documentation that describes the feature (PDF Builder enhancements - - What's New (appeon.com)) mentions "Creating links in a PDF document that points to other areas of the document"
I have reviewed the examples that describe creating PDF documents (Examples - - Application Techniques (appeon.com)) but:
- Cannot get most of them to work
- Do not see a part where you can create a page number and how to reference that page number in a table of contents (TOC)

I also can't really see whether you can reference an imported datawindow in the same way that you can reference another page in the PDF Document. I have been able to use the PDF Builder datawindow import feature to create a PDF file that has the following format:

- Title page 
- Main Table of Contents (a datawindow)
- Consolidated Summary Report
-- Each department from the main TOC
-- TOC for the department listing the financial statements 
-- Consolidated summary for the dept
--- List of individual financial statement reports

So, it is a nested format and is made up of imported datawindow reports. From the help documentation on the Appeon site, I see that the PDF Document image contains a PDFPage object which contains the PDFText objects which I guess will be used for the page numbering. I do not see PDF Datawindow Import on the PDF Builder overview page (https://docs.appeon.com/pb2022r3/application_techniques/ch08s04s01.html) but each imported DW seems to be counted as individual PDF pages when I run a PDF pagecount. 

Could anyone provide a simple example of a PDF builder script that:
- Adds a page number to an imported datawindow
- Creates a table of contents with a link to the imported datawindow's page

Thank you very much for any help or further documentation that you can provide!

Dennis

I think that I have a workable script. I can add the text object (Chapter) to the imported datawindow and then click the Table of Contents item to go to it. Hope this helps.

long 					ll_return, ll_page
string					ls_name, ls_text

PDFdocument 			        lpdf_doc
PDFpage					lpdf_page, lpdf_current_page
PDFtext 				lpdf_text, lpdf_title, lpdf_chapter
PDFTableofContents		        lpdf_toc
PDFtableofContentsitem	                lpdf_tocitem



ll_return = dw_1.Retrieve()
IF ll_return < 0   THEN
	MessageBox('Retrieve', 'Failed')
END IF

lpdf_doc 		= Create PDFdocument
lpdf_page 		= Create PDFpage
lpdf_text  		= Create PDFtext
lpdf_title  	        = Create PDFtext
lpdf_chapter 	        = Create PDFtext
lpdf_toc 		= Create PDFtableofContents

//Get the page count to locate the newly imported DW. Should be zero
ll_page = lpdf_doc.getpagecount( )
	
ll_page ++	
	
//Import the DW that we retrieved earlier	
lpdf_doc.importdatawindow( dw_1)

//Assign the DW page to lpdf_current_page
lpdf_current_page	= lpdf_doc.getPage(ll_page)
ls_name 		= lpdf_current_page.Name

//Create TOC page - From the Help Docs
lpdf_title.content = "TableOfContents"
lpdf_title.font.fontsize = 36
lpdf_title.x = lpdf_page.getwidth( )/2 -lpdf_title.width/2

lpdf_toc.setstyle(PDFTableOfContentsStyle_Classic!)
lpdf_toc.setrightmargin( 100)
lpdf_toc.setleftmargin( 100)
lpdf_toc.settopmargin( 50)
lpdf_toc.settitle(lpdf_title)

lpdf_chapter.content = "Chapter1"
lpdf_tocitem         = lpdf_toc.additem(lpdf_chapter)	//Add to the table of contents

lpdf_current_page.addcontent(lpdf_chapter)	//Add the Chapter 1 heading to the imported DW page

lpdf_doc.settableofcontents( lpdf_toc)

ll_return = lpdf_doc.save( "c:\share\pdftest.pdf")

MessageBox("Generate", "Done")

RETURN SUCCESS
