using datamodules

[domkop]

i am working with a paradoxdatabase.
now someone sugested to use datamodules to keep all the datasources and tables on one place.
now i want to try to use this but how do i change the objects on a datamodule on runtime.
some tables have filtering or indexes that need to change when changing the working form, orcan i use datamodules only if the data does not change.
i use different forms that use the same database
does anyone knows a site for this??
i never used datamodules before, i always placed the objects on the forms i am working with.

You just need to refer to the datamodule in the implementation section of the unit:

implementation
Uses Datamodule1,Unit1;

The data module is ideal for sharing a data connection, imagelist, actionlist/menus or any other non-visual components across forms. Changing data at runtime is no different in a data module than if you place the table/query/etc... on the form.
