If you open one of the .CC files in the dUFLP in the source code editor

This will help you find a lot of items ... it's not perfect, but what is? :)
To use the controls, before opening the form designer:
set procedure to :dUFLP:FormCntl.cc
Then create a new form, and the controls should be on the Component
Palette. You don't need to copy FormCntl.cc (or other files from the
dUFLP) into your application folder, that's poor design. This kind of

your own library folder and use the same controls in multiple
applications, allowing consistency ... a change in the original control
will appear in all forms (apps, etc.) that use that control. If you put
them in the folder with your application, then changes do not "trickle
