DocumentLibraryVersions Collection
DocumentLibraryVersions DocumentLibraryVersion |
The DocumentLibraryVersions property of the Microsoft Office Word 2003 Document, the Microsoft Office Excel 2003 Workbook, and the Microsoft Office PowerPoint 2003 Presentation objects returns a DocumentLibraryVersions object. The DocumentLibraryVersions object represents a collection of DocumentLibraryVersion objects.
Using the DocumentLibraryVersions Collection
Use the DocumentLibraryVersions object with documents stored in a Windows SharePoint Services document library on the server to determine whether versioning is enabled for the active document and, if versioning is enabled, to manage the document's collection of DocumentLibraryVersion objects.
Each DocumentLibraryVersion object represents one saved version of the active document. When versioning is enabled, a new version is created on the server when the actions listed below occur; additional versions are not created each time the user saves changes to the open document.
- Check In
- Save - A new version is created on the server when the user first saves the document after opening it. Additional changes saved while the document is open apply to the same version.
- Restore
- Upload
The DocumentLibraryVersions object model is available whether versioning is enabled or disabled on the active document. The DocumentLibraryVersions property of the Document, Workbook and Presentation objects does not return Nothing
when the active document is not stored in a document library or versioning is not enabled. Use the IsVersioningEnabled property to determine whether the document library is configured to save a backup copy, or version, each time the document is edited on the web site.
Example
The following example checks to see whether versioning is enabled for the active document and, if so, displays information about each saved version.
Dim dlvVersions As Office.DocumentLibraryVersions
Dim dlvVersion As Office.DocumentLibraryVersion
Dim strVersionInfo As String
Set dlvVersions = ActiveDocument.DocumentLibraryVersions
If dlvVersions.IsVersioningEnabled Then
strVersionInfo = "This document has " & _
dlvVersions.Count & " versions: " & vbCrLf
For Each dlvVersion In dlvVersions
strVersionInfo = strVersionInfo & _
" - Version #: " & dlvVersion.Index & vbCrLf & _
" - Modified by: " & dlvVersion.ModifiedBy & vbCrLf & _
" - Modified on: " & dlvVersion.Modified & vbCrLf & _
" - Comments: " & dlvVersion.Comments & vbCrLf
Next
Else
strVersionInfo = "Versioning not enabled for this document."
End If
MsgBox strVersionInfo, vbInformation + vbOKOnly, "Version Information"
Set dlvVersion = Nothing
Set dlvVersions = Nothing
