Documentation (Custom Data View Templates)

rbuser

Is there any better developer orientated documentation for the
classes involved in creating custom Data view templates?

The standard BDE and core classes are listed briefly in the developers
guide,
but I was looking for something which had either examples of how to
implement data views and what is acheivable, along with information for the
ADO and interbase classes aswell?

I am trying to implement some custom data views for our application, which
is database independant, so that our customers have template reports which
they can modify to their own ends without having to get too close to SQL.

One approach is to use custom dataviews. With this approach the end-user
selects File | New from the Data workspace and selects one of your data
templates from the New... dialog.

Another approach is to use the Data workspace and the visual Query tools to
create dataviews and then export them to a .dtm file or a database template.
With this approach the end-user selects File | Import... from the Data
workspace and then imports one your TdaDataModules.

There are some tech tip articles in the DADE thread of the Tech Tips
newsgroups that provide an overview of the DADE architecture.For more
details on Custom DataViews, check out the RBuilder\Demos\EndUser\Custom
DataViews examples.
Beyond that, there is the ReportBuilder source code.

The daDBBDE.pas unit contains some ancestor custom dataview template classes
that are used in the Custom DataViews examples. These clases could be copied
and implemented for ADO or IBExpress.
