Hi Christof,

I've create a class holding two textboxes as

Public WithEvents SystemBox As TextBox
Public WithEvents DescriptionBox As TextBox

However, I get the message 'object does not source automation events'

Where did I go wrong?

You need to declare them As MSForms.TextBox, as Excel has its own
TextBox object.
