    Tech Tip: Replacing Built-in Dialogs/Forms in ReportBuilder
    -----------------------------------------------------------

    ReportBuilder has an open architecture for replacing any of the built-in
    dialogs. You can replace any of the built-in dialogs by creating a new
    form that inherits from an abstract ancestor and then registering it as
    the new built-in dialog.

    For example to replace ReportBuilder's preview dialog you could

    1. Create a new Preview dialog by renaming ReportBuilder's default
    preview dialog, then doing a SaveAs to save it under another unit name.

    The default dialog resides in RBuilder\Source\ppPrvDlg.pas and the form
    is called ppPreviewDialog. You should assign your form a unique name,
    for example, myPreviewDlg, and save the unit to another name. Also save
    the unit to the directory where your other forms are stored (not
    RBuilder\Source).

    2. Make desired changes.

    You will notice that the preview dialog inherits from an ancestor
    TppCustomPreviewDialog - this ancestor resides in ppForms.pas (where all
    the abstract ancestor forms for ReportBuilder are defined).

    3. Register the new form.

    Declare an initializtion section at the bottom of the unit:

    initialization

    ppRegisterForm(TppCustomPreviewer, TmyPreviewDlg);


    4. Add the new unit to your project and compile.

    Now your preview dialog should be automatically created and destroyed by
    ReportBuilder. The two page preview dialog in the
    RBuilder\Demos\Reports\Demo.dpro was created this same way. The only
    difference is the ppRegisterForm call is in then OnClick event of the
    button.
