Do not forget XE2 $IFDEF VER230

Fri, 16 Sep 2011 18:51:01 -0500

Don't forget $IFDEF VER230 : when migrating to XE2 the sources of DiSqlLite3, many "E2251 : Ambiguous Overload" compiler errors were detected. The previous XE compiler however worked like a charm. The DiSqlLite3 contained units with "compatibility" code with functions like code UTF8ToUnicodeString to accomodate pre-Delphi-6 compilers. Those parts were excluded from compilation by $IFNDEF for Delphi 6, Delphi 7, up to Delphi XE. But of course, not yet for Delphi XE2 ! Therefore the XE2 compiler rightly complied those parts, which then rightly clashed with the XE2 RTL equivalents, displaying the dreaded "Ambiguous Overload" error. Simply adding the appropriate XE2 VER230 defines to remove those parts ALSO from the XE2 compiler fixed the problem. Certainly the DEFINEs could be organized to fall back automatically on the LAST version for which the code was written, VER220 (and not on one of the first Delphi version, VER80). This would allow this library to automatically compile for XE2, XE3, XE4 etc. Anyway, no doubt Delphi Inspiration will update their product shortly, and add it to the fast growing "XE2 compatible 3rd party component" list.

Turned down for Ekon Spring Generics presentation

Wed, 27 Feb 2008 18:51:01 -0500

End of January, I offered to present the Genercis at the Ekon-Spring conference which was scheduled end of February. I surely was later than the "Call For Paper" deadline, but I naively assumed that when a product has 4 major innovations (dbx4, Blackfish, Asp.Net 20 and the Generics), it would not be too difficult to add an hour to the schedule, which as far as I know did not include any Generics presentation. Well, I was badly wrong. So maybe next time, I'll try to be within deadlines, and they might consider my offer. Meanwhile, since I still believe that Generics are a very important topic for Delphi developers, I took some of the examples I had prepared, and changed the slides into <%delphi_generics_tutorial>an article on this site.
