UserControl Let/Get Property as Object

[gavio]

Here's my goal:

Option Explicit
  Private m_txt As TextBox

Public Property Let txt(new_txt As TextBox)
  Set m_txt = new_txt
End Property

Public Property Get txt() As Object
  Set txt = m_txt
End Property

Now,... i have tried everything but have not be able to figure out how to:

1. get this Property ("txt") to VB's "Properties" box and
2. get list of all TextBox-es on a Form where my UC is located into "Properties" box where "txt" Property is now shown (from 1.; if possible).

Hope this makes sence.
