Validate All Textbox Controls Without Control Arrays

This a small modification on Patrick Lockefeer's code, (http://www.freevbcode.com/admin/Admin.asp?ID=7514), to clear all textboxes. This time it checks that all the textboxes in a form are complete. If they are all complete it returns true, if any are incomplete it returns false. As with the original code, it is done without control arrays.
