RE: How to unload all userforms when opening a new file?

[quote user="quasi_modo"]Is there a way to force all userforms to unload when the operator opens a new file?[/quote]

First, write a class that handles the OnDesignFileClosed event.  That would be the time to clean up UserForms.

Next, write something to close the open UserForms.  You need to iterate the forms collection.  I think you can do something like this...

Dim Obj As Object

For Each Obj In VBA.UserForms
  Debug.Print Obj.name
  End If
Next Obj
