[Solved] Word VBA force save as .docm

by


In order to hijack the native “SaveAs” dialog in Word, you need to lever the Application-level event for DocumentBeforeSave, and then call the FileDialog manually, in order to validate the extension.

1. Create a standard code module and name it modEventHandler. Put the following code in it.

Option Explicit
Public TrapFlag As Boolean
Public cWordObject As New cEventClass

'You may not need these in a DOCM, but I needed to implement this in an ADD-IN

Sub TrapEvents()
If TrapFlag Then
    Exit Sub
End If
Set cWordObject.DOCEvent = Application
TrapFlag = True

End Sub
Sub ReleaseTrap()
If TrapFlag Then
    Set cWordObject.DOCEvent = Nothing
    Set cWordObject = Nothing
    TrapFlag = False
End If
End Sub

2. Create a Class Module called cEventClass and put this code in the module:

Option Explicit
Public WithEvents DOCEvent As Application

Private Sub DOCEvent_DocumentBeforeSave(ByVal Doc As Document, SaveAsUI As Boolean, Cancel As Boolean)
' Do not prevent SAVEAS for *other* documents
If ObjPtr(Doc) <> ObjPtr(ThisDocument) Then
    Exit Sub
End If

If SaveAsUI Then
    ' The user has invoked SAVE AS command , so we will hijack this and use our own FileDialog
    Call CustomSaveAs(Doc)
    ' Prevent duplicate appearance of the SAVEAS FileDialog
    Cancel = True
End If
End Sub

Private Sub CustomSaveAs(ByRef Doc As Document)
Dim fd As FileDialog
Dim filename$

Set fd = Application.FileDialog(msoFileDialogSaveAs)
fd.Show
If fd.SelectedItems.Count = 0 Then Exit Sub
filename = fd.SelectedItems(1)
If Not Right(filename, 4) = "docm" Then
    ' ### DO NOT EXECUTE this dialog unless it matches our .DOCM file extension
    MsgBox "This document should only be saved as a DOCM / Macro-Enabled Document", vbCritical, "NOT SAVED!"
Else
    fd.Execute
End If
End Sub

3. In ThisDocument module, do the following code:

Private Sub Document_Close()
Call modEventHandler.ReleaseTrap
End Sub

Private Sub Document_Open()
Call modEventHandler.TrapEvents
End Sub

How Does This Work?

ThisDocument raises the Document_Open event which calls on the TrapEvents procedure.

TrapEvents procedure creates a WithEvents instance of Word.Application class, exposing additional events to automation. One of these is DocumentBeforeSave.

We use the DocumentBeforeSave event to trap the SaveAs operation. If the User has requested a SaveAs, then we force the dialog with logic as created in CustomSaveAs procedure. This uses simple logic to test the file extension provided, and prevents the document from being saved if it is not a DOCM extension. If the FileDialog does receive a valid DOCM extension, then we Execute the dialog which saves the file as the new name.
