Non-Data aware controls and ADO

Hi,

I just got my form working with ADO thanks to some posts in this news group,
but I have a couple of questions.

I need to load a graphic based on a value that is returned but not
displayed.

1. How do return a recordset?
2. How do I get data without using data aware controls?

Thanks

Use the OnDataChange event of the datasource to change the contents of the
image.

ps. The parameter passed by OnDataChange is nil if the entire record changed
(when cursor moves) or a field if only that field changed.

If you use a query to get the data from a database table(s), for
example, you can refer to any of the returned values several ways:
dataset.fieldbyname('myfield').value
dataset.fields[2].asstring (the third field in the dataset)
etc...
Look up tquery, ttable, in help. browse thru the properties and 'see
also' lists.
