Blog		 If you're still using Paradox for any of your business database applications, you need to put a plan together now for converting to another development tool or at least understand what the future is likely to hold. If you're a power-user or researcher working with data, stick with Paradox at least for now.

JavaScript uses functions and loosely typed parameters. Function definitions must come before their usage so the usual preference when adding JavaScript to HTML pages is to include them between the head tags.

Tip		 If you are a single developer, try to find someone else to exercise your program. As the programmer, you have certain ideas of how a user will use your application. These ideas probably apply to about half the users.

KB Post		 Use a file server (not a workstation) to store your data, disable Oplocks on the filer server, and configure the BDE (local share to true and optimize if desired). Finally, if workstations are crashing, fix em so they don't. You want clean running computers that don't crash.
