EKON 15 conference news and discount (German text at the end of the blog post): Cary Jensen presents the keynote @caryjensen #ekon

Posted by jpluimers on 2011/10/11

EKON 15 – first day has many English sessions

From 26 till 28 of October, I’ll be speaking at the 15th EKON conference at the Renaissance Hotel in Düsseldorf, Germany.

I just sat next to the conference organizer, and he proudly announced that well known and long time Delphi guru Cary Jensen will be presenting the keynote on the evolution of Delphi from Delphi 1 to XE2.

I still have the disks marked “Wasabi” and “Mango” from the early 90s (and funny that Microsoft is using the same name for a 7.5 product, where Delphi 1 was a real revolution).

Next to the German sessions, there will be English sessions as well: Cary also does his other sessions that day (on cross platform development, windows services, and RESTful webservices).

Being a German conference, most of the other sessions will be in German, but it is good that the English ones are all in one day: you get a one-day visit to conference as a non-German speaker, get a discount and visit the beautiful city of Dusseldorf (especially the Altstadt is recommended).

Contact me for more information on discounts: there are both discounts for the English day and the full the whole conference.

On the EKON 15 site there is a nice conference planner and session overview.

Last but not least, on friday after the conference, Edwin van der Kraan and I will present a full day Delphi XE2 workshop covering x64, new VCL and of course FireMonkey cross platform development (so bring your Mac and iOS devices with you!).

15. EKON Konferenz – Delphi XE2 und mehr…

Vom 26. bis zum 28. Oktober findet die 15. Entwickler Konferenz (EKON) im Renaissance Hotel in Düsseldorf statt. Ich werde als Speaker ebenfalls vor Ort sein.

Als ich gerade mit dem Organisator der Konferenz zusammen saß, verkündete er mir stolz, dass Cary Jensen, bekannter und langjähriger Delphi-Guru, auf der EKON 15 eine Keynote zu Delphis Evolution von Delphi 1 zu XE2 halten wird.

Ich bin immer noch im Besitz von Disketten aus den frühen 90er Jahren, die mit „Wasabi“ und „Mango“ beschriftet sind (witzig dabei ist, dass Microsoft den gleichen Namen für ein 7.5-Produkt nutzt, während es bei Delphi 1.0 eine richtige Revolution gab).

Neben den deutschen Sessions werden auf der EKON auch Sessions auf English angeboten: Cary wird unter anderem auch über Cross-Plattform-Entwicklung, Windows Services und RESTful Web Services sprechen.

Zwar werden die meisten Sessions auf Deutsch gehalten, jedoch gibt es diesmal eine Besonderheit bei den englischen Sessions: Diese finden an einem Tag statt!
Somit können auch die Nicht-Deutschsprachigen für ermäßigten Eintritt an den Sessions auf Englisch teilnehmen und ganz nebenbei die schöne Innenstadt Düsseldorfs erkunden
(besonders die Altstadt ist sehr empfehlenswert).

Zu guter Letzt präsentieren Edwin van der Kraan und ich am Freitag einen ganztägigen XE2 Power Workshop zu x64, New VCL und natürlich zur FireMonkey Cross-Plattform-Entwicklung (bringen Sie also Ihre Macs und iOS-Geräte mit!).

Bei weiteren Fragen, Interesse und Infos über die Ermäßigungen können Sie mich gerne kontaktieren (Ermäßigte Preise gibt es sowohl für den English-Day als auch für die Gesamtkonferenz). Auf der Website finden Sie eine übersichtlichen Zeitplaner, die Sessions im Überblick und alle weiter Informationen zur Entwickler Konferenz.

Bring back support for Smart Device Extensions – Customer Feedback for Microsoft

Posted by jpluimers on 2011/10/11

Having done quite a bit of Windows CE development work in .NET, I totally support the below UserVoice request: re-add support for Windows CE in Visual Studio 2010.

Please vote both the underlying Microsoft connect request, and the uservoice entryif you support it too!

Bring back support for Smart Device Extensions

Microsoft caused outrage when without warning or explanation they dropped support for the Smart Device Extensions. Meaning that there is no support for both managed (Compact Framework) and unmanaged (C++) development for the Windows CE platform.

Microsoft promised support would be added by the time VS2010 was released but then back tracked, to date the official line is use VS2008. This product is nearly 4 years old, it is becoming increasingly more impractical to use VS2008 solely for the purpose of developing for the Windows CE platform. Many development teams invested heavily in the benefit of having a single UI for both embedded and desktop development, with the advent of the Compact Framework skill sets and more importantly the code base could easily be shared across platforms. This is now no longer true, as the desktop development/source control/build/test environments have moved on the embedded development environment is stuck in the past. This means duplication of code, duplication of effort and increased cost.

Anyone wanting to start developing for Windows CE has to first buy an MSDN subscription because you can no longer buy VS2008 retail.

As support for Smart Devices has been inherent in VS since VS2003 many people have been caught out when upgrading to VS2010, in many cases those who make their living in the embedded world are now stuck with no upgrade path. Microsoft has refused to comment or discuss the future of embedded development, this silence has forced many to look at alternative platforms.

One of the top voted suggestions on the Connect site was to restore Smart Device Extension support in VS2010, Microsoft has ignored this in typical fashion.

See the Connect Item.

Forcing decimal dot (.) for number parsing

Posted by jpluimers on 2011/10/11

Small but useful, especially in countries that have something else than a dot (.) as decimal digit separator (all of the green countries: probably more than you’d thought).

The C# sourcecode is really simple use a NumberFormatInfo instance (or an instance of another class implementing IFormatProvider) in a Single.ToString call:

                float number = 3.1415;
                NumberFormatInfo numberFormatInfo = new NumberFormatInfo();
                numberFormatInfo.NumberDecimalSeparator = ".";
                numberFormatInfo.NumberGroupSeparator = string.Empty;
                string numberString = number.ToString(numberFormatInfo);

The classes implementing IFormatProvider are CultureInfo, DateTimeFormatInfo and NumberFormatInfo.
