The Dutch stop of the RAD Studio In Action LIVE! tour is on September 7th.
The venue location is via Holiday Inn Leiden Hotels: Haagse Schouwweg 10, 2332 KG Leiden, The Netherlands.
It is close to the advertised “Amsterdam Netherlands” (about half an hour drive), close to the A44 highway and close enough to public transport. And it is indeed on Saturday September 7, 2013

It has been in the queue for a really long time. In fact, all started when chatting with Anders Ohlsson during the inception of the Embarcadero MVP program.
But then the paper work (you know, the thing with written signatures, fax machines, etc) got buried under some projects that lasted both a lot longer than initially anticipated, and were far more consuming also meaning I could not make it to the developer conferences I originally planned.
Recently, I dug out the paper work, then found out that Jim McKeeth – now leading the MVP program at Embarcadero – could lessen the paperwork substantially.
A few manual steps were still involved on both sides, but now I am on the MVP Directory | General.
There is more to it. This fall, I will not only be making it to, but also speaking during at least 3, maybe more Delphi related events in Europe:
Given the time frame, and increase of information about a Delphi for Android product, it might be out or available for beta blogging by then. You can sign up for the beta here, and according to the roadmap it is estimated for release later this year. I hope to be able to play with that soon enough to at least demo a few bits and pieces of it using my Nexus 4 and HTC Sensation on some of those events.
Hope to see some of you there!

I might need this for some really old stuff, so here is a reminder: Unspecified Error in Delphi 2007 on Windows 8 | ACMer.
It does work on Windows 7: Problem installing Delphi 2007 on Windows 7 64 Bit Enterprise – Stack Overflow.

While researching some other historic information about Delphi, I bumped into this thread: New DPMI host – delphi.
If is a small thread describing what kinds and versions of DPMI hosts were available to run Turbo Pascal based programs.
DPMI stands DOS Protected Mode Interface: a way for real mode DOS programs to access protected mode features (mainly memory above the 1 megabyte barrier).
I had plainly forgotten that the DPMI host shipped with Delphi 1, and wasn’t aware you could have a 32-bit DPMI host at all.
Some other memory related abbreviations from that era: Read the rest of this entry »

Something overwrote the Browsing Path of my Delphi XE installation.
Symptoms:
It was faster to examine the Delphi XE Library registry settings from Ken White than comparing them with a backup or a fresh Delphi XE install.
Now it works fine…

Just found out this the hard way, glad I found it soon which prevented me from doing like Ondrej Kelle – Google+ – Wasted a few hours with this….:
Debugging 64 bit Delphi applications with Delphi XE2 on Windows 8 does not work
Problem: Debugging a 64 bit Delphi application using Delphi XE2 with Windows 8 results in the error Disconnected session.
Solution: Windows 8 is not a supported platform for versions of Delphi prior to Delphi XE3. To get debugger support for 64 bit applications on Windows 8, you must get Delphi XE3. If you are upgrade sensitive, Embarcadero recommends you get Support and Maintenance along with your next purchase. Support and Maintenance guarantees you all updates for 1 year and gets you 3 support incidents in addition.
The proposed solution is to upgrade to at lease Delphi XE3, but this project is not ready to upgrade just yet.
Anybody with a real workaround (apart from downgrading to Windows 7)?

Peter Leslie Morris asked if Delphi already incorporates the `yield` keyword that C# had introduced in C# 2.
Delphi doesn’t, but for the people interested what it does in C#:
Basically `yield` is syntactic sugar to make it a lot easier to write methods that return enumerators of some sort.
It delays (hence the yield keyword) execution until the enumerator as actually being used.
It is one of the hardest C# things to master (it is the most complicated transformation in the compiler, followed by anonymous methods – well maybe with the exception of async/await), but it can be very useful.
VB.NET doesn’t have it either (thanks André!) has it too, but and also has iterator blocks.
Some start posts on yield:

StackOverflow user opcOde wrote something interesting:
Writing device drivers in delphi is hard to impossible.
Here is an attempt to write drivers in delphi.
It is funny to see the link pointing to the DelphiBasics site: Advanced Delphi Driver Development Kit – DelphiBasics.
On my list of things to remember: might come in very useful one day (:
Note that opcOde also has an interesting blog: opc0de | just another enthusiastic coder.

I was called by a client that didn’t want to do maintenance on an old Delphi application, but wanted to get dir of an I/O Error 131:
I/O Error 131: ERROR_NEGATIVE_SEEK
MessageText: An attempt was made to move the file pointer before the beginning of the file.
Tough luck: psychic powers told me someone is using an unsigned 32-bit integer to access a file using traditional style Assign/Reset/Seek/Read/Close patterns that Delphi kept as intrinsic routines for Turbo Pascal backward compatibility, and that file has grown over 2 gigabyte in size.
I quickly found an import file had grown over the 2 gigabyte, so this was indeed the case.
The original developers didn’t do the file access using the 64-bit Seek/Position of the TStream descendant TFileStream.
Too bad, as now someone has to dig through the mothballs to find the sources (if they survived 3 different version control system switches), create a working development environment, and fix the bug.
Another instance where technical debt in IT raises its ugly head and the compound interest is really expensive.
