In an EditBox or TextBox, you can select the first occurrence of the search word in the string by positioning Control.SelStart = ATC(cVar,memo) and Control.SelLength = LEN(cVar). If you need to highlight each occurrence in a single EditBox, you'll need to use a RichTextBox to display it, and then insert formatting codes in the string to boldface or underline or italicize each occurrence by searching the string and using STUFF() or the equivalent to add control sequences as needed. See the MSDN Library documentation on the RichTextBox control; there are classes in the VFP6 FFC which might be useful for inserting the control codes.
