DLL Error

rbuser

Hi,

I have a main program with report builder components calling a DLL with
report builder components. When I run the program I get this message: Class
EFileError with message 'A class named TraCodeModule already exists.'
The Report builder component names are all defaults for both the main
program and the DLL called.
I am using RB 6.

Thanks,
Clem

Try redesigning your application to be built with run-time packages rather
than using a .dll. Delphi packages (i.e. .bpl's) are .dll's that have a
special format that makes them easy to use. When you build your application
you can have a small .exe that contains only your app code. All of the
Delphi and RB classes can reside in their current packages. You can also
build your own packages that require the Delphi and RB packages. Using this
strategy the RB classes will only be loaded a single time.

Here are some options:

1. Compile your project using the Delphi run-time packages option. This will
create a small .exe. You then distribute the runtime packages along with
your executable file.

2. Store you report definitions to .rtm files or a database. Thus the report
definitions are stored outside the .exe and only loaded as needed. If you
have a large number of reports, this can drastically reduce the size of the
.exe.

3. Compile all of your reports into a Delphi package. Then your application
only loads the package as needed.
