You can use buf.RecNo and buf.FieldByName('field_name') OR buf.Fields[i].
This is not direct memory access.

The newer Delphi compilers are slower than D5 D7... Why? Because those old Delphi compilers only targeted one platform, and they could optimise the crap out of it because they hand no cross-platform worries. FPC is written with easy maintenance and extensibility in mind. So obviously you will take a small performance hit. I think that is a reasonable trade-off. Either way, I still don't think FPC is slow - compared to other compilers like GCC, Java etc. Also, 90% of the time FPC only needs to compile the actual units that changed - while you are developing your project.

Re: [fpc-pascal] GUI confusion
Hi Fred Yes ! I am evaluating both Lazarus and fpGUI. At the moment I am steering towards fpGUI. I like FLTK but I don't like C++ and the FLTK bindings are not so great. Understanding GTK or QT under the hood is a massive undertaking. So far fpGUI reminds me of FLTK(but it prettier) I can imagine, without heroic effort, that people would be able to look inside it and see what's going on. It looks to be 173K lines, while FLTK is about 100K(I forgot the exact number). However I am betting it will be much easier to read then C++ and of course I don't even have to read the source to understand it! It's just nice to know that it is possible for me. Being able to fix bugs yourself is important to me. A small readable codebase means autonomy, projects do get abandoned and/or people can get sick and are unable to maintain them. fpGUI seems like a really good project.

I tryed googling, but didn't have much luck ...
Rather late than never. ;-)
In your .lpr file, add the tiLog unit to the uses clause, and also the
unit representing the logging method you want to use. For this example,
lets say you want to log to a file, then include the tiLogToFile unit in
the uses clause too.
eg:
uses
{$IFDEF UNIX}
cthreads,
{$ENDIF}
Classes
,tiLog
,tiLogToFile
;
Log ago that would have been enough, and the class would have registered
itself. But we have since changed the design so the end-user can
specific which logging method they want (if multiple logging options are
enabled), and the developer can decide where for example a log file must
be created. Anyway, now register the log to file class.
The most basic one is...
gLog.RegisterLog(TtiLogToFile);
Or a more complex one could be...
gLog.RegisterLog(TtiLogToFile.CreateWithFileName('.',
ExtractFileName(ParamStr(0))+'.log', True));
Now your application is all set. Oh, if you compile your project under
Linux or FreeBSD, remember to enable threading support, because the
tiOPF log functionality uses threads.
Now to output log message, the tiLog unit must be in a uses clause, then
simply call:
Log('Some cool message', lsDebug);
or
LogError('Some big error occured', False);
Please see the various LogXXX methods in the tiLog unit. The parameter
names will describe what each parameter does.
Here is a more useful example that I use in my desktop applications. The
end-user can control what logging style they want. Multiple logging
styles can be enabled at the same time too. eg: Log to File and Log To GUI.

The problem is also that I'm trying to implement this hack in an old version of pascal, v2.2.2 for which I only have the compiler basic rtl stuff - that's why I'd just like some info for a quick hack eg some bullets or some idea what I need to do eg to read the no or string in eg cell x23 of sheet jim in fred.xls.

[fpc-pascal] fpGUI documentation
Apologies if this is a double post, I sent this, this morning but it does not seem to have made it to the list: Hi Graeme I am really impressed with fpGUI. Judging from the examples and the comments of others, this is exactly what I need. The examples will go a long way in helping me understand it but I seem to be hitting a number of roadblocks with the documentation. The class index on the site appears to be a dead link: http://fpgui.sourceforge.net/apidocs/index.html In the documentation folder this file is German only: layouting_de.html (I can try Google translate or Learn German!) I don't seem to be able to figure out how to generate the documentation in the folder, I tried running all three build scripts: :bash build_html.sh FPDoc - Free Pascal Documentation Tool Version 2.6.2 [2013/03/17] (c) 2000 - 2003 Areca Systems GmbH / Sebastian Guenther, s...@freepascal.org exception at 00483246: Unable to open file xml/corelib/fpg_cmdlineparams.xml. bash build_ipf.sh FPDoc - Free Pascal Documentation Tool Version 2.6.2 [2013/03/17] (c) 2000 - 2003 Areca Systems GmbH / Sebastian Guenther, s...@freepascal.org exception at 00483246: Unable to open file xml/corelib/fpg_cmdlineparams.xml. bash build_rtf.sh FPDoc - Free Pascal Documentation Tool Version 2.6.2 [2013/03/17] (c) 2000 - 2003 Areca Systems GmbH / Sebastian Guenther, s...@freepascal.org exception at 00483246: Unable to open file xml/corelib/fpg_cmdlineparams.xml. I found this PDF online: http://geldenhuys.co.uk/articles/fpgui.pdf It's from 2008 and it sound like you have done a lot of work since then, is this document still valid? Once I know what I am doing maybe I can help with the documentation a bit?
