Also remember you can pass anything from form to form even forms, or 
pass forms to code modules. Also you can declare a form

For example if  you used alot of say columnviews all over a large 
project and did the same sort of thing to the columnview in all the 
forms, simple example, allow the user to change the font of a columnview 
and save it to a settings file via a pop-up menu over the columnview, 
you could have a general module in your project, and pass the columnview 
to that module, do whatever on it you wanted. Then you have a single few 
lines of code you re-use in dozens and dozens of situations.

e.g I have a module I call modUtil and puts lots of stuff in it which is 
used all over the place

Public Sub Columnview_SetFont(cvw As Columnview, Settings_Section As String)
'----------------------------------------------------------------------------------------------------------------
    'Attempts to change the font of a columnview and save to settings
'---------------------------------------------------------------------------------------------------------------

    Dialog.font = cvw.font
    If Dialog.SelectFont() Then Return
    cvw.font = Dialog.Font
    Settings[Settings_Section & "/" & cvw.name & ".font"] = 
cvw.Font.ToString()

End
