Using Events with the Application Object in MS Word - vba

Question

Ms Word does not want to load my add-in. I want to call a userform on print event. Here is my code:
in module 1
Option Explicit
Private Sub App_DocumentBeforePrint(ByVal Doc As Document, Cancel As Boolean)
'Debug.Print Now & " " & "App_DocumentBeforePrint: " & Wb.FullName
Userform1.Show
End Sub
Sub InitializeApp()
Dim X As New EventClassModule
Set X.App = Word.Application
End Sub
in Document module
Private Sub Document_Open()
Call InitializeApp
End Sub
in EventClassModule
Public WithEvents App As Word.Application
in Userform1 Mode
Option Explicit
Private Sub UserForm1_Initialize()
End Sub
I used this 2 links to help me write this code
1) https://msdn.microsoft.com/en-us/library/bb221264%28v=office.12%29.aspx
2) https://msdn.microsoft.com/en-us/library/gg597509%28v=office.14%29.aspx
Can anyone tell why my code does not work?

Answer 1

As explained in the first link you show, the procedure App_DocumentBeforePrint needs to be in the CLASS module (EventClassModule, in your explanation), not in Module 1.
Other than that, it's not clear what you mean by "my add-in". Usually, I'd think of a template (or COM add-in) when this term is used that's being loaded as an add-in. I'm concerned whether Document_Open is actually being triggered to initialize your events. This event, in the ThisDocument module (in reality, it's a class) will only fire when the document containing this code is opened...

Answer 2

For anybody else who comes across this thread like I did, this is what worked for me:
in module 1
(your module shouldn't contain the event-based sub; also, X needs to be declared as a global variable rather than within the 'InitializeApp' sub)
Option Explicit
Dim X As New EventClassModule
Sub InitializeApp()
Set X.App = Word.Application
End Sub
in Document module
Private Sub Document_Open()
Call InitializeApp
End Sub
in EventClassModule
(your Class Module should contain the event-based sub)
Public WithEvents App As Word.Application
Private Sub App_DocumentBeforePrint(ByVal Doc As Document, Cancel As Boolean)
'''Your procedure here
End Sub
