TdaSession.Getdatabaseforname during runtime

rbuser

I am using Intraweb 7 with Delphi 6 and RB 7. We are also using DBisam as
Database engine.
I just created a report using PPreport (queries and code were done in the
report ) object only (I used to add Query and Datapipeline components).
When I try to run it I get the following error:
TdaSession.Getdatabaseforname : no Tdbisam object found for specified name,
A separate Database connection is required for each thread.
is there a way to specify the database session used by the report during
runtime.
Thanks,

You need to create a thread-safe container for the report. I recommend that
you use a TDataModule. Place the TppReport and a TDBISAMDatabase component
on the datamodule. From the Data workspace of the Report Designer, select
File | Datasettings and configure the datasettings to use the
TDBISAMDatabase component. Now delete the old queries and create new ones
using the new datasettings. Each web request should create a separate
instance of datamodule - and thus a separete report instance and associated
database connection object.

1. If you are building a web application, you may want to consider using RB
Server Edition to implement the web reporting and then invoke it from your
intra web app.

2. There is some good information on thread-safety in the online help topic
for TppReport.BackgroundPrintSettings. The Background printing feature was
added as of RB 7.02...
