title: VBA: Detect changes in any textbox of the userform
body: <p>There is a userform that has many textboxes and I need to detect changes in each. So I have write a subroutine for every textbox in the form and it turns out a large piece of code.
  As the code for every textbox is the same I want to optimize it. So is it possible to write just one subroutine that detect changes in any textbox of the form?</p>
