This class is written for VDF15 and up.

Queensday in The Netherlands, but also a GOOD day for vdf-guidance because of an exciting new contribution called autocomplete written by David Martinko.
Speed user entry. See results matching what you type. Choose an entry from the list to complete your entry, or use it to make that the active record.
No DLL's, no ActiveX controls, written completely with native dataflex code. A sample view is included for the Order Entry Sample Workspace so you can start testing it right away and have a sample on how to use it. Another great feature is that the same code has worked from vdf7 thru vdf9.1 without ANY code changes. This makes an excellent portable control. Vdf6 required some minor changes to get it working (which will probably work in vdf5 also) however I have no plans on continuing support for the Vdf6.
