[AccessD] Populating a form with attributes of a class

If the string contains the library and class names he could use a string just like you would in: 
	CreateObject("Excel.Application")

or in the case of a custom object:
	CreateObject("MyLibrary.MyClassObject")

Arthur,

Are you wanting to use data in an object to populate a form?  Or am I
misreading you?  AFAIK, there is no way to pass an object as a form
parameter.  You can pass a string, but that's about it.  And I don't
think you can reference an object by such a string value.  You would
need some kind of container, like a collection, for your objects, which
you could then reference by a key name.  Note this collection would need
to be global, but if you look at it like any other application-wide
collection, it's really the same thing.  The Forms or Tabledefs
collections are really nothing more that "system" global collections. 
While globals are typically considered a "bad thing" by most developers,
sometimes you can't get around them.  I think in this case, where you're
not keeping an armada of global objects available and just a single
collection, it shouldn't be too painful for you. :)
