Application events

Events for the Application object occurs when a workbook is created, opened or when a sheet in any workbook is changed. If you want to write event procedures for the Application-object, you will have to create a new object with the keyword WithEvents in a class module. After the new class module is created you can attach macros to the following events:

Create eventmacros for the Application object

Start the Visual Basic editor.
Select the desired project in the Project-window.
Insert a new class module by selecting the menu Insert | Class Module.
Activate the new class module and rename it, e.g. AppEventClass
Copy and paste these example macros to the new class module:

Public WithEvents Appl As Application


Private Sub Appl_NewWorkbook(ByVal Wb As Workbook)
    ' your code here
    MsgBox "A new workbook is created!"
End Sub


Private Sub Appl_WorkbookBeforeClose(ByVal Wb As Workbook, _
    Cancel As Boolean)
    ' your code here
    MsgBox "A workbook is closed!"
End Sub


Private Sub Appl_WorkbookBeforePrint(ByVal Wb As Workbook, _
    Cancel As Boolean)
    ' your code here
    MsgBox "A workbook is printed!"
End Sub


Private Sub Appl_WorkbookBeforeSave(ByVal Wb As Workbook, _
    ByVal SaveAsUI As Boolean, Cancel As Boolean)
    ' your code here
    MsgBox "A workbook is saved!"
End Sub


Private Sub Appl_WorkbookOpen(ByVal Wb As Workbook)
    ' your code here
    MsgBox "A workbook is opened!"
End Sub

After you have finished editing the event macros for the Application object, you have to add some code to the module ThisWorkbook to activate the new event macros:

Dim ApplicationClass As New AppEventClass


Private Sub Workbook_Open()
    Set ApplicationClass.Appl = Application
End Sub

After you run the Workbook_Open procedure, the events attached to the Application object are activated.
