Abstract: Listen to the replay and read the chat room log of Chris Hesik's interview on debugging in Delphi 2005
Listen to the audio replay.
This is a log of the chat room during the live audio chat from December 15, 2004 on
Delphi 2005 with Chris Hesik. Chris discusses debugging
support in Delphi 2005.
Note: This log is only the chat room
transcript. There is much additional information covered in the audio
replay that is not available in this chat log. For all previous and
upcoming live chats, see https://bdntv.borland.com/chat.html.

jkaster : "Using Non-Breaking Breakpoints in
Delphi" by Cary Jensen
jkaster : tx for reminder, mrpmorris

jkaster : is the QualityCentral web site
jkaster : davidi : "Is there a limit to
the number of processes I can debug?" - there
shouldn't be. The debugger doesn't limit you in any way.
jkaster : davidi : "Can you step from
managed code into native code?" - Not in Delphi 2005.
We're still actively investigating it.
jkaster : abauer : "What about true hybrid
managed/unmanaged debugging including stepping across that
boundary?" - for now, if you want to debug a mixed
application, you'll need to debug those sides separately. We do
this with the IDE itself. For example, set a breakpoint on the native
side, then detach from the native debugger, attach the managed process
and debug that, and so on.
jkaster : bmcgee : "Can we control where
things get logged? For example, logging the call stack on a breakpoint
to CodeSite or a text file." - All the log information goes
to the event log. You can save the event log to a file.
jkaster : davidi : "What's the
difference between "Multi-Process" and "Active
Process" Debugger Views" - I mentioned this in my
blog. Some views in the IDE will allow you to look at information from
more than one process at a time, such as the thread and modules views.
Most views use just the active process, like the CPU view, watch
jkaster : Atmapuri : "Are there any plans
to support user programmable debugger (watches and tooltips)?"
- part of a batch question ...
jkaster : basa : "VS.NET 2005 introduces
custom visualizers in the debugger
Is there a similar functionality in D2005? If so, how do I write my own
visualizers, if not, do you plan to add such a functionality to
Delphi?" - currently we don't support
visualizers. It got dropped from the list for this release, but
it's near the top of the list for a future release. We'd like
to make it as compatible as possible with the way VS will do it so
people don't need to learn two methods.
jkaster : davidi : "Do you have any
suggestions for debugging optimized native code (besides turning
optimizations off)?" - There is a blog entry on this.
jkaster : jkaster : "any plans to support
edit/continue?" - I think MS announced C# will have this as
well (as VB.NET). We'll look at doing this on the managed side
since the framework will evidently support it. Please put requests like
this in QC and vote on them.
jkaster : basa : "what happened to remote
debugging in D2005? I consider this as mission critical, do you have
any plans to integrate it again in the upcoming D2005 service
pack?" - It was removed from Delphi 2005 simply because it
was a resourcing issue. It's quite a bit of work, and since the
debugger changed drastically for Delphi 2005, we had to unfortunately
drop it. We haven't gotten a whole lot of feedback on its
importance, so again use QC to indicate its importance. There may also
be a survey coming up on this soon from Michael Swindell (Product
jkaster : aohlsson : "Why is the
"Thread Start" messages in Red? Isn't red for
errors?" - typically red IS for errors. I'm not
sure why it's red initially, but you can change the colors used in
the event log in IDE preferences
jkaster : Serge_d : "Do you plan to
support DEBUG/DEPLOY personalities/compile mods in Delphi
200x" - We do support it on the C# personality. It's
actually project manager rather than debugger related. Some other IDE
engineers are looking at this.
jkaster : jkaster : "CodeGuard is a great
debugging feature of C++Builder. Will we see anything like that for
Delphi applications?" - I don't know. We're not
working on it currently. There are some third party tools available for
this rignt now.
jkaster : Serge_d : "Do you plan to
support Inheritance chain in Exception class for Win32" -
Please clarify this question.
jkaster : basa : "could Borland help Simon
Kissel to bring us a remote debugger for CrossKylix?" -
we've certainly heard about this request
jkaster : from abauer: re: Debug/Release options; It was
on the list for Delphi 2005, but was one of the unfortunate victims of
jkaster : Tjipke : "(Just joining, so
sorry if it is allready asked) But is it normal that I can't change
values during .Net debugging? (like in win32)" - not
normal, just a limitation we need to address.
aohlsson : basa : "for remote debugging:
what is the QC-number?" - There doesn't seem to be one,
so please add one. When you add it, it should pop up here -
jkaster : Serge_d : "Exception when
reraised does not know about intercepted exception, there is no option
to do reraise with history like available in .Net" - I
might need an example or test case for this. Please submit a report to
QC and let us know the number.
jkaster : tx, serge. Let us know QC#, if it already
exists that's fine.

mrpmorris : Hi Anders
mrpmorris : Hello ladies
mrpmorris : John K, HowToDoThings.com is written in plain
ASP. Version 2 is in the works written with ECO + ASP.NET
mrpmorris : So I'll write the article once it is
mrpmorris : audio is good
Serge_d : Hi everybody
basa : suggestion for jkaster: it would be nice if
questions asked would also show up in text in the public chat window
Editor's Note: they don't appear until the response to
the question is completed.
Tjipke : Certainly need to address it!
Serge_d : I will follow up with QC, but I believe it was
in QC already. I will reraise question in NG and QC.NG
mrpmorris : thanks
Tjipke : bye
