>The way Incremental Search is implemented in Tastrade, Order Entry looks good, but the coding is to steep for me. I copied the sample code from Solutions, and can adapt that to my own program. but it does not work quite in the same way as the Tastrade sample does.

What exactly do you want for a behavior (I'm not familiar with the TasTrade example).

Look in the Files section under classes for the two Auto-Complete classes you can use, File#1044 and File#9548

Also, depending on the Style and IncrementalSearch properties of your Combo, there is functinoality built in to the VFP Base Classes.
