To quote the Apple statement:
we are relaxing all restrictions on the development tools used to create iOS apps, as long as the resulting apps do not download any code. This should give developers the flexibility they want, while preserving the security we need.
Which seems to mean you can use both Mono (using MonoTouch) and Flex to develop your Apple iPhone and iPad apps.

Recently, I was at a client where in a project strings had to be split from:
'FI-150 1U; FI-049-I L=20 MM;LET OP LASVORM'
Into:
'FI-150 1U''FI-049-I L=20 MM''LET OP LASVORM'At first sight, this looks simple: Semicolon Separated Values and you are done.
Not so fast Mr Smart Alec: watch the optional spaces!
The best thing for problems like these is to start with an empty implementation that some units tests covering it.
I use DUnit for Delphi unit testing.
Unit testing should go with code coverage, but there are few Delphi code coverage articles.
I’ll get into code coverage later on, as I’m working with two of the code coverage people to get this to work nicely with Delphi 2010.
Mock objects can be a good addition to unit testing too, so in a future article, I will cover using mock objects with Delphi.

While writing this blog entry, I’m installing my new copy of Delphi XE (formerly called Delphi 2011 by some people).
Delphi XE and RAD Studio XE got RTM today, and are now available for purchase.
Contact my colleague Gwan Tan if you want to order it from Dutch speaking countries, and Thorsten Nannen if you want to order it from German speaking countries. Read the rest of this entry »

Anthony Frazier mentions two very true paths for optimizing your Delphi compile times:
To get rid of the second, you should split your interface and your implementation.
Often, one of these two solutions work for that well:
Only if those options do not work, then start using Delphi SpeedUp by Andreas Hausladen.

Be sure to watch the radstudiodemos project at sourceforge.
It contains the RAD Studio Demos from Embarcadero in this SVN repository.
Which means that the demos of the current RAD Studio version are there, and Embarcadero is filling it with the Demos from the upcoming Delphi XE version.
In fact, quite a few Delphi XE demos have been checked in already.
John Kaster will put on the C# version of DbxUtils on-line there soon.

When you write .NET 4 software, you want to deploy it to your clients, so they need to install the .NET Framework 4.
On fully patched Windows Server 2003 x86 installations, the (optional) Windows Update for Microsoft .NET Framework 4 for Windows Server 2003 x86 (KB982671) usually results in this error:
Installation Failure
Error Code: 0x80246002
Try to install the update again, or request help from one of the following resources.
It fails during download, so it does not even reach the install phase.
Don’t loose too much time resolving this: The usual solution for 0x80246002 as described in KB958056 does not work.
The systems affected don’t have anti-virus or similar software installed, so disabling those won’t work: there is nothing to disable.
What does work is the suggestion a bit lower in the 0x80246002 update fails search results Read the rest of this entry »

Next week, I’ll be speaking at Delphi Live 2010 in San Jose, California.
, USA.
At the end of september, I’ll be speaking at EKON 14, in Darmstadt, Germany. My 14th appearance at EKON!
Delphi Live (sessions in English):
EKON 14 (Sessions auf Deutsch / in German):
Hope tho see some of you people at one of those events.
I will bring some USB audio equipment, so I might do a bit of geek stuff doing ASIO audio on those events too.

On the Embarcadero forum, Jolyon Smith asked about the underlying meaning of the 64-bit Pulsar statements in the updated Roadmap.
He did not ask for an exact date, but what level of 64-support is the current goal.
Allen Bauer (Chief Scientist at Embarcadero) was kind enough to put up a few answers.
A few quotes are below, please read the full thread titled Embarcadero Discussion Forums: Roadmap: Clarification Required Please … for the exact answers.
It basically boils down to this: Read the rest of this entry »

It is good to see the cross breeding effect works:
Last week, the Visual Studio 2010 Productivity Power Tools added Quick Access Extension, which is the Visual Studio equivalent of the Delphi RAD Studio IDE Insight.
It is a keyboard shortcut (Delphi: F6 or Ctrl-.; Visual Studio: Ctrl+3) to search and execute things defined by the environment:
Delphi has a few options that Visual Studio hasn’t and vice versa, but it comes really close.

One of the toughest parts on creating a new [Archive.is] CodePlex project is choosing a license.
As Jeff Attwood wrote a couple of years ago, choosing a license – any license – is important, because if you don’t, you declare an implicit copyright without explaining how others could use your code.
In addition to that, Jeff published a list of licenses with a one-line phrase describing them, so it becomes easier to start making a choice.
Last year, ShreevastaR extended that list in his answer to this StackOverflow.com question on CodePlex licensing.
Brian Campbell did the same a few months later on another StackOverflow question about CodePlex licensing.
There are many more StackOverflow.com threads like those 2, and they give similar results.
The reason I want to put up a CodePlex project, is to put my sample code for conferences, blog articles and course examples on-line so they are easier to share with other people.
Most is from Visual Studio or Delphi projects using languages C#, VB.NET and Delphi.
Some of it are batch-files, XSD, XSLT, or other small snippets to get stuff working. Read the rest of this entry »
