Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. The following code will get the last modified date of a document and subtract it from the current date, and then compare it to a user-defined value.

Sub CompareDates()
   Dim aDocSaved
   Dim intNumDays
   On Error GoTo errHandler

   'Assigns date and time document last saved to a variable.
   aDocSaved= ActiveDocument.BuiltInDocumentProperties _
   (wdPropertyTimeLastSaved)

   'Compares variable to now then assigns the integer
   'difference to another variable.
   intNumDays = CInt(Now() - aDocSaved)

   'Compares difference in days to 7 and branches based on result.
   If intNumDays > 7 Then
      MsgBox ("This file is overdue")
   Else
      MsgBox ("This file is still current")
   End If
   errHandler:
   If Err <> 0 Then MsgBox ("Please save the active document.")
End Sub
