Programatically sort pages in a Visio Document using VBA - vba

Question

Does anyone know a method to sort Visio pages alphabetically using VBA?
I looked to see if a method such as vzdVisioDocument.Pages.Sort exists, but found nothing in documentation or through internet searches.
Do I need to write my own sorting function using the Application.ActiveDocument.Pages.ItemU("Page Name").Index property? That seems to be the method suggested by recording a macro of the action.

Answer 1

So that wasn't as painful as expected. With vzdVisioDocument as an already defined Visio.Document:
' Make a collection of titles to iterate through
Dim colPageTitles As Collection
Set colPageTitles = New Collection
Dim intPageCounter As Integer
For intPageCounter = 1 To vzdVisioDocument.Pages.Count
colPageTitles.Add vzdVisioDocument.Pages.Item(intPageCounter).Name
Next intPageCounter
' For each title in the collection, iterate through pages and find the appropriate new index
Dim intPageIndex As Integer
Dim varPageTitle As Variant
For Each varPageTitle In colPageTitles
For intPageIndex = 1 To vzdVisioDocument.Pages.Count
' Check to see if the title comes before the index's current page title
If StrComp(varPageTitle, vzdVisioDocument.Pages.Item(intPageIndex).Name) < 0 Then
' If so, set the new page index
vzdVisioDocument.Pages.ItemU(varPageTitle).Index = intPageIndex
Exit For
End If
Next intPageIndex
Next varPageTitle
' Clean up
Set colPageTitles = Nothing

I mentioned this in another comment, but when I made some test pages, it was always shuffling the pages around when I ran it because I the way that this is implemented, I don't believe that Exit For should be in there.
I also swapped the comparison to StrCompare due to personal preference along with the order of the for loops.
Sub PageSort()
Dim titlesColl As Collection
Set titlesColl = New Collection
Dim i As Long
For i = 1 To ActiveDocument.Pages.Count
titlesColl.Add ActiveDocument.Pages.Item(i).Name
Next i
Dim title As Variant
For i = 1 To ActiveDocument.Pages.Count
For Each title In titlesColl
If StrComp(ActiveDocument.Pages.Item(i).Name, title, vbTextCompare) < 0 Then
ActiveDocument.Pages.Item(title).index = i
End If
Next title
Next i
Set titlesColl = Nothing
End Sub

Private Sub reorderPages()
Dim PageNameU() As String
Dim isBackgroundPage As Boolean
Dim vsoPage As Visio.Page
Dim vsoCellObj As Visio.Cell
'// Get All Pages
Dim i As Integer
For Each vsoPage In ActiveDocument.Pages
i = i + 1
ReDim Preserve PageNameU(i)
PageNameU(i) = vsoPage.NameU
Next vsoPage
For i = 1 To UBound(PageNameU)
Set vsoPage = vsoPages.ItemU(PageNameU(i))
Set vsoCellObj = vsoPage.PageSheet.Cells("UIVisibility")
isBackgroundPage = vsoPage.Background
'// Make foreground page to set page index
If isBackgroundPage = True Then
vsoCellObj.FormulaU = visUIVNormal
vsoPage.Background = False
End If
vsoPage.Index = NumNonAppSysPages + i
'// Set to background page
If isBackgroundPage = True Then
vsoCellObj.FormulaU = visUIVHidden
vsoPage.Background = True
End If
Next i
End Sub
