I'm a M2 UNIX programmer and programming in MS Windows is pretty new to me. I'm writing a program that can allow a user to select a record from a listbox. Now this list of record can easily exceed the 64K barrier. So my questions are: 1. How can I interrupt the user when he's trying to scroll down/up, so I can load the next/prev 64K segment from the file ? 2. And even if that can be done, how do I maintain the scrollbar to show the position of the bar within the whole database, but not just within the 64K segment ?? 3. If that is totally impossible, can anyone tell me where can I find information (books maybe) about writing a widget ( or whatever it's called in MS Windows ) ? Thanks! _______________________________ End of Message _________________________________ Yours Sincerely, |\ |||| ||||||||| (tm) |||\ |||| |||| Samuelson S.
