This macro example loops through each document in the Documents collection and determines whether the path and name of the document you want to open match the path and name of a file already open in Word. If there is a match, the macro displays a message box stating that the document is currently open in Word. If there is no match, then the macro opens the document.

   Sub IsDocAlreadyOpen()
      Dim sDocToOpen As String
      Dim dDoc As Document
      ' Replace the following example document path and file
      ' with the path and file you want to open.
      sDocToOpen = "C:\My Documents\MyDoc.Doc"
      ' Loop through all open documents.
      For Each dDoc In Documents
         'Test for match.
         If UCase(sDocToOpen) = UCase(dDoc.Path & "\" & dDoc.Name) Then
            ' If open, display a message.
            MsgBox sDocToOpen & " is already open."
            Exit Sub
         Else
            On Error Resume Next
            ' Open the document.
            Documents.Open (sDocToOpen)
            ' If the document does not exist or the path/name is
            ' incorrect an error will occur. This error trap
            ' displays the error information.
            If Err <> 0 Then
               MsgBox Err.Description
            End If
            Exit Sub
         End If
      ' Loop to next document.
      Next dDoc
   End Sub
