Introduction

Word has a sophisticated Table of Contents feature that automatically creates a table of contents from designated headings in a document.  Access reports don’t have such a feature, but I managed to create one using VBA code, custom database properties and some Word features.

The Orders Report

The sample database for this article, Table of Contents Report (AA 236).accdb, has tables from the old Northwind sample database, and a standard stepped Orders report:

This is a long report, so it would be handy to have a table of contents listing the page for each Customer ID.  Here is a high-level description of how I did it:

1. Export the report to Word RTF format.
2. Using VBA code working with the RTF document and a recordset of CustomerIDs for customers who have orders, search for each CustomerID and get the number of the page it is on, and save the CustomerID and page number to a table.
3. Create a subreport (rsubTOC) whose record source is a query based on the table filled with current Customer ID and page number values.
4. Make a copy of rptOrders (rptOrdersWithTOC), and insert the subreport into the report header.
5. Make a complex expression to display Roman numerals for the TOC page numbers, and Arabic numerals (starting with 1) for the regular page numbers.

Here is the first page of the report with a Table of Contents:

And here is the first page of the body of the report:

The procedure listed below does the work of saving the page numbers to the table used as the subreport’s record source:

Public Function GetReportPages()

 On Error GoTo ErrorHandler

    'Close existing RTF file if necessary

    strCurrentPath = Application.CurrentProject.Path & "\"

    strWordRTFFile = strCurrentPath & "Orders.rtf"

    Debug.Print "Word RTF file: " & strWordRTFFile

 On Error Resume Next

    Set doc = appWord.Documents(strWordRTFFile)

    If Not doc Is Nothing Then

       doc.Close savechanges:=wdDoNotSaveChanges

    End If

 On Error GoTo ErrorHandler

    'Export Orders report to Word RTF file

    strReport = "rptOrders"

    DoCmd.OutputTo objecttype:=acOutputReport, _

       objectname:=strReport, _

       outputformat:=acFormatRTF, _

       outputfile:=strWordRTFFile, _

       autostart:=False

    Set doc = appWord.Documents.Open(strWordRTFFile)

    doc.Select

    appWord.Selection.WholeStory

    'Clear old TOC records

    strTOCTable = "tblTOCPageNos"

    strSQL = "DELETE * FROM " & strTOCTable

    DoCmd.SetWarnings False

    DoCmd.RunSQL strSQL

    'Set up recordsets of customer codes to search for and table

    'for storing Customer IDs and page numbers

    strQuery = "qryCustomerIDs"

    Set rstSource = CurrentDb.OpenRecordset(strQuery)

    Set rstTOC = CurrentDb.OpenRecordset(strTOCTable)

    appWord.Visible = True

    'Turn off spelling and grammar checking

    With appWord.Options

       .CheckGrammarAsYouType = False

       .CheckGrammarWithSpelling = False

       .ContextualSpeller = False

       .CheckSpellingAsYouType = False

    End With

    Do While Not rstSource.EOF

       strCustomerID = rstSource![CustomerID]

       With rstTOC

          .AddNew

          ![CustomerID] = strCustomerID

          'Find Customer ID in Word document

          appWord.Selection.Find.ClearFormatting

          With appWord.Selection.Find

             .Text = strCustomerID

             .Replacement.Text = ""

             .Forward = True

             .Wrap = wdFindStop

             .Format = True

             .MatchCase = False

             .MatchWholeWord = True

             .MatchWildcards = False

             .MatchSoundsLike = False

             .MatchAllWordForms = False

          End With

          appWord.Selection.Find.Execute

          Set sel = appWord.Selection

         'Retrieve page number from Word document

          intPageNumber = sel.Information(wdActiveEndPageNumber)

          Debug.Print "Customer ID " & strCustomerID _

             & " page no.:  " & CStr(intPageNumber)

          ![PageNumber] = intPageNumber

          .Update

       End With

       appWord.Selection.WholeStory

       rstSource.MoveNext

    Loop

See download code below for entire code including error handler.

The expression that creates the page numbers references several invisible textboxes in the report footer (the yellow ones – that is my convention for invisible controls):

The page number expression is:

 =IIf(([Page]>[txtTOCPages].[Value])=True,("Page " & [txtCorrectedPageNo].[Value] & " of " & [txtCorrectedNumPages].[Value]),"Page " & RomanNo([txtPage].[Value]))

As is often the case on Access reports, I sometimes found it necessary to reference the value of a textbox, rather than the actual value that is the control source of the textbox.  Here are the control sources of the txtCorrectedPageNo and txtCorrectedNumPages textboxes referenced in the above expression:

 =Val([txtPage].[Value])-Val([txtTOCPages].[Value])

 =Val([txtPages].[Value])-Val([txtTOCPages].[Value])

txtTOCPages has this control source:

 =GetProperty("TOCPages","")

This custom database property is saved from this procedure, which is run from the report’s Open event, which also puts up a message box asking if you want to recreate the Table of Contents, and runs the GetReportPages procedure if you click Yes.

 Public Function GetTOCPages() As Integer

 On Error GoTo ErrorHandler

    'Get number of TOC pages and save to a custom database property

    strReport = "rsubTOC"

    DoCmd.OpenReport reportname:=strReport, _

       View:=acViewPreview

    Set rpt = Reports(strReport)

    intTOCPages = CInt(rpt![txtNumPages].Value)

    Debug.Print "TOC Pages: " & intTOCPages

    DoCmd.Close objecttype:=acReport, _

       objectname:=strReport

    strPropertyName = "TOCPages"

    lngDataType = dbInteger

    Call SetProperty(strPropertyName, lngDataType, intTOCPages)

 ErrorHandlerExit:

    Exit Function

 ErrorHandler:

    MsgBox "Error No: " & Err.Number _

       & " in GetTOCPages procedure; " _

       & "Description: " & Err.Description

    Resume ErrorHandlerExit

 End Function

References

The code in the sample database needs the following references (in addition to the default references):

Microsoft Word 14.0 Object Library

Microsoft Forms 2.0 Object Library

Microsoft Scripting Runtime

If you import code or objects into a database of your own, you may need to set one or more of these references.  The version number may differ, depending on your Office version; check the version you have.  References are set in the References dialog, opened from the VBA window.  For more information on working with references, see Access Archon #107, Working with References.
