Previewform looks strange

rbuser

Hi

Sometimes when the previewform is coming up it looks a little bit strange:
on the left side the printer-symbol is missing and on the right side there
is a big panel with a size of 1/4 of the whole screesize. Is that a known
problem and what can i do?

Best regards

You can try updating to RB 7.03 and you can updating your video driver.

I do not notice anything like that on my machine.

Another option would be to replace the preview form with a custom version of
our own. Most of the dialogs/forms in RB are replaceable (with the
exception of the report designer and its toolwindows and toolbars).

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.
