How to ask for confirmation before allowing a Word document to close? - vba

Question

I work with 2 different keyboard layouts (qwerty and azerty), and am constantly switching between the two using Alt-Shift. Sometimes when I reach for Ctrl-Z to undo, I get instead Ctrl-W which closes the document. Generally speaking I would in these situations get a Save Prompt, which would alert me to my mistake. However, I am now using OneDrive, with Autosave on the documents I'm working on. As a result, there is never this save prompt. The document is instantly closed and, worse, the undo that I was trying to effect is no longer present when the document is re-opened.
I would like to use VBA attached to the Normal Template, such that, on closing any document created with the VBA template, I will check to see if Autosave is turned on, and if it is, confirm before closing with a messagebox.
Obviously if the user doesn't confirm (e.g. chooses Cancel) then the document should not be closed.
Initially I put my code on Document_Close, but soon realised that here it's too late to Cancel the close. This is no good to me.
Then, based on some online code, I put my code in a class module (EventClassModule). In the ThisDocument module, I initiate the class, and activate the event handler.
My code doesn't ever seem to run, or in anycase, breakpoints don't kick in.
I'm a little unsure of where Normal stops and my normal document begins...
In ThisDocument of Normal Template, I have this VBA
Dim X As New EventClassModule
Sub Register_Event_Handler()
Set X.App = Word.Application
End Sub
Private Sub Document_Open()
Register_Event_Handler
End Sub
And I have a class module called EventClassModule with the following
Public WithEvents App As Word.Application
Private Sub App_DocumentBeforeClose(ByVal Doc As Document, Cancel As Boolean)
Dim res As VbMsgBoxResult
If Me.AutoSaveOn Then
res = MsgBox("OK to Confirm", vbOKCancel, "Closing Document")
If res = vbCancel Then
Cancel = True
End If
End If
End Sub
I would like a prompt to confirm saving, any time a document is closed and the autosave option is turned off.

Answer 1

The Document_Open event handler will only fire if the Normal template is opened via File | Open. To get code to respond when starting Word you need to use an AutoExec routine. Simply rename your routine as below. You can find further info on Auto macros here
Public Sub AutoExec()
Register_Event_Handler
End Sub

Answer 2

Here is an easy way, include a method like this:
Public Sub DocClose()
' Disables Ctrl + W (but not other close methods, e.g. Alt + F4, menus, [X])
' Your code here:
ActiveDocument.Close
End Sub
Basically there are some method names that are used internally by MS-Word, and if you include them in your code they will prevent the default action. If you leave the sub empty it will effectively disable Ctrl + W.

Advantage 1 of this technique
If you use Public WithEvents App As Word.Application and your project gets reset for any reason, and fails to restart... App will be Nothing and none of the events will fire.
Advantage 2 of this technique
On the occasions that you actually want to close a document... with this technique you wont get bugged by a (soon to become) annoying confirmation message - just sayin ;-)
