>I'd like to implement a mechanism similar to Autocomplete , but i do not want new values to be entered into the Autocomp table, nor modified, nor deleted. The Autocomp table is, thus, just a lookup table. Can i tweak Autocomplete to do that, or should i mimic it's behaviour and create the whole stuff from scratch??

Hi Jaime,

It has been discussed in AutoComplete Table Update Help Thread #1039481. You can add your idea to VFP Wish List.
