I want to build a program to look up a sentence in a database (DBF or SQL 7) like MSDN do by 'index topic', i.e. program will looking up after each character typed, and display the most matched sentence.
Who know about how to do this, please help me.
I have not done this, however, I would check into the InteractiveChange event and the KeyPress method. You can get it to then run a program or SQL statement each time the user enters a stroke from the keyboard. Also, make sure that your form is refreshed each time there is code run, else the user may never see any change.
A neat site for VFP 6 (or other) is at: ourworld.compuserve.com/homepage/rhendricks/misclang.htm#VFOXPRO
