Creating

There is no point creating a dialog box that does exactly the same as one of the applications standard built-in dialog boxes
To create a new userform (Insert > Userform) or right mouse click in the Project Window and press ( ?? )
A userform can have horizontal and vertical gridlines to help you align your controls
All forms are based on the Userform object
Userforms are actually classes so you can include Lets and Gets.
You can also include private variables to a form (just like classes).

Initialising

Private Sub UserForm_Initialize() 

End Sub
