If you mean while your app is off, you can save your db's size and check it later. The chances are, if the db changes, the size will change too

While a table is running, use a callback function with the BDE.  It is called cbTABLECHANGED.  Also check out the DBICheckRefesh and DBIForceRefresh BDE functions.

BTW--check those all out in the BDE API Help file.

Need more help, just write,

Try the component on this page--here is the description:

Delphi table change notification component with example: This sample component does all the BDE API work for you to give notification when a Paradox table has changed.  Fully configurable; check interval time and custom event allows you to do anything you want when the table has changed. Simply install the new TTable component (TRegisterTable in RegisterTable.pas) and compile the included project. This component will work with all table types, but will only use the callback with Paradox table types.

If you like this, just reject the current answer and I'll post this as the answer.

Have fun,
Scott
