Non-implicit windows with no reference. Bad practice?

General
1

Simple (I think) question.

If I have a app where I want multiple instances of the same window, is it bad practice to not save references to those instances as properties somewhere?

I have no need to access anything on those windows from the main window, so do I need to keep references around that I need to clean up when the windows are closed?

It is not necessary.
Have a look at WindowCount in docu.

API2:
App.WindowCount
App.WindowAt

However, it will list every window of any type, including dialog boxes that are open etc.
You would have to do something like

if App.WindowAt( n ) IsA MyWindowClass then
   // You have one of your 'Document' windows
end if

There’s also an App.Windows iterable, you can use like this:

For each ThisWindow as DesktopWindow in App.Windows
   If ThisWindow IsA MyWindowClass Then
      MyWindowClass(ThisWindow).SomeMethodOrPropertySpecificMyWindowClass
   End If
Next

I actually don’t need to reference the windows after opening them, but it’s good to know that I can.

You both answered my question though.
Thanks
