>Hi to everyone, someone knows a way to make the Dropdown Combos to work similar to the Quick Books ones, meaning, when you enter a portion of the name, it shows the rest (if it exists) and also, the remaining portion of the searched record is highlighted. Seems quiet laborious to be developed.

I've seen this in several frameworks. I know the combos in VFE have the .AutoFill property (which activates this sort of behavior), and there was also a (public domain one?) by Doug Hennig. Look for "autofill combo", probably even here in downloads.
