If there is a match, the macro displays a message box similar to the following, stating that the document is currently open in Word: If there is no match, 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
