Demos do not work since upgrade 10 10.05

rbuser

Hello

Since upgrading to 10.05 I notice that the demos (Interbase and BDE) do not
work. Also I notice that they have changed. plItem now using queries instead
of a table object. Has that been there a while.

I used to use the demo app and just point it to a copy of my live database
and it would work ok no problem. Always used to do this when I upgraded to
look at some of the new features in the the new release before doing things
on my live environment and code.

Am I missing something here? It has changed right ?

Hi Mark,

Which version of ReportBuilder are you upgrading from? The new end-user
architecture has been in place since RB 10.0 was released and should require
no action on your part (database wise) to get working. Is there something
special about your database that is different from the one I would be using
on my machine? What is happening when you run these demos? Are you
receiving any errors?

Looking at the database settings on euDatabase they are
PATH=D:\Program Files\Borland\Delphi7\RBuilder\Demos\Data
DEFAULT DRIVER=PARADOX
ENABLE BCD=FALSE

When I launch I get the following message:
"Error: FolderPipeline : 'plFolder' could not be opened"

I can usually use the Interbase demo and just change the alias to my
database or just enter the path on the database object and it has been fine.

You are correct in that I last did this when we were on 7.04 and we jumped
to 10.04 so did not notice the change. As 10.05 came out shortly after I am
now testing our app on 10.05 and am now going through things when I noticed
the difference.

I should have also said the the error in my previous post is when I turn off
the data dictionary. With the dictionay on I get the following error:
"Error:DataDictionary.TablePipeline 'pltable' could not be opened"

I have placed dbgrids on the form and set the table properties to active and
the data is displayed so my database is there and tables set correctly.

Any clues?

Hi Mark,

I am unsure about the cause of this error. We have also not heard of this
before from any other customers. Are you certain your library path is
pointing toward the correct source? There must be some difference between
your setup and mine. Are you able to drop a TTable on a form and
successfully access it from a report and pipeline?

I added a TTable, Datasource, Report and BDEPipeline. Connected table to
DBDEMOS alias and then made active.

Double clicked on the report component, added a dbfield and hey presto all
OK.

Still cant get the demos to work tho...

I have traced it so far to here

if (FDesigner.DataSettings.DataDictionary <> nil) and
(FDesigner.DataSettings.UseDataDictionary) and
not(FDesigner.DataSettings.DataDictionary.ValidSettings) then
begin
FErrorMessage := FDesigner.DataSettings.DataDictionary.ErrorMessage;
Exit;
end;

In the ValidateSettings Function

Its exits with the message i posted earlier

const aPropertyName: String): Boolean;
