Report Explorer Not Seeing Database Name

rbuser

Hello,

For some reason we are having trouble getting Report Explorer to see the
"database name". We have established a connection to the NexusDB database,
but when we go into Report Designer and then go to the data tab, and then
click on File > Data Settings. The database name is not there, but Session
Type and Database Type are.

Any clues on how to resolve this, and get the database name seen? We have
already went through all settings and don't see anything that could be
wrong.

Thank you,
Larry

The database connection object should reside on the same form as the
TppDesigner component. Once you pick the session type, then the connection
object should appear in the database name list.

Try configuring the TppDesigner.Datasettings at Delphi design-time and then
check them at run-time.

The database component is on a data module. It used to work this way with
our older version of report builder. Are you saying that now I need to move
it to the same form? Does this apply only to the database component or
other connection components such as transport and server components?

The designer database settings show up in object inspector at design time,
but it just doesn't show in the designer at run-time.

- At Delphi design-time, the list of available database connection objects
is built by using a call to the Delphi IDE.

- At run-time there is code that can look thru the applications datamodules
(i.e. Screen.DataModules[] array). Make sure that an instance of the
datamodule is instantiated prior to instantiating the form containing the RB
components.

- It might be that the name of the object returned by the Delphi IDE is
prefixed by the datamodule name (i.e. myDataModule.Database1), at run-time
RB will not do that.

- At run-time you can trace the RB source code to see how this works. In
RBuilder\Source\daDB.pas, the method TdaSession.GetDatabaseNames.
