RAP problem in a specific machine

rbuser

I run into a RAP problem which occurs in a SPECIFIC machine only. It does
not depend on Delphi/RB versions because I tried two different applications
that have been developed with Delphi5 and Delphi6. The problem has something
to do with the global variables. In some cases the reports run and when I
open them for editing and go to calc page I see the event handler in red
with the message "Variables cannot be compiled". If the report is
complicated it may not be able to run.
I do not have the RAP code to put any diagnostic messages and run it in that
specific machine so I am just asking for any possible explanation. Maybe RAP
uses something that is not correctly installed?
This problematic machine runs on Win2000.

Have not heard of this before. There is nothing in RAP that requires any
special version or capabilities of Windows. I use Windows 2000 on my Tech
Support machine and Windows XP on my R&D machine but never encountered any
differences. (However, I know you described in a prior thread that you have
some very complex RAP reports).

Does the problematic machine have a different language setting? I am just
trying to guess why it might behave differently.

Nard,
We run several Win2000 and XP machines so there is no problem with that. I
use RB the last 5 years and never had a similar problem. As you mention I
recently encountered a problem (see
thread 21/07/04) but it happened in all machines. It is a complex report and
the problem went away when I reduced the depth of nesting of procedures. I
have no explanation. However the present situation is different - seems to
be that it has something to do with the specifc machine.
Language settings are the same with other machines that work fine.
Anyway if I had the RAP source then I would be able to do some debugging.
Any chance that digital-metaphors will make RAP source available in the
future?
Thanks

Unfortunately we cannot make the source code to RAP available. The
competition blatantly copies our trade secrets when this occurs. To date no
competitors have anything close to RAP or RB Server. The reason for this is
that they do not have the source code. I'm not being paranoid, this has
historically proved itself out. Borland does not release the source to the
Delphi compiler or the Delphi IDE. Though I wish that they did. I know
exactly how you feel. ReportBuilder has to integrate into Delphi and we
encounter many AV's and weird behaviors that we have to work around to get
things to work.

The difference between us and Borland is that if you send us an example of
something that causes an issue, we will research it and try to fix it.
