Like When DelphiSpeedup cannot register itself in Delphi on Windows Vista/7/8, GExperts also had problems installing on Windows Vista and up when Delphi runs in a non-elevated account.
It said it installed fine, but it didn’t get included when Delphi was started. The reason was that it got installed in the wrong root key.
What happened is that GExperts installed itself into the HKLM root:
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Borland\BDS\5.0\Experts]
GExperts=C:\Program Files (x86)\GExperts for Delphi 2007\GExpertsDelphi2007.dll
But it should have installed itself in the HKCU root: Read the rest of this entry »

If you run FastMM4 in FullDebugMode, then here are two tips that new (and sometimes existing users) often overlook:
- If you set the
FullDebugMode directive in the IDE, build your project.
- Don’t forget to give your EXE access to FastMM_FullDebugMode.dll (x86), or FastMM_FullDebugMode64.dll (x64) which are stored in the FastMM4 download and in the precompiled directory of the source code.
Either put that DLL in your path, or copy it to your EXE directory.
- Make sure your EXE can write in the directory of the EXE.
The first makes sure all units are compiled with FullDebugMode (Delphi does not always do that automagically).
The second makes sure your EXE can access the DLL that writes out your *MemoryManager_EventLog.txt file containing memory leaks and other issues FastMM4 detected.

Every now and then I need to go back to an old Delphi version, which nowadays means try and get it and all the tools installed on something newer than Windows XP.
When installing on Windows Vista and up (I usually run Windows 7 or 8.1), the DelphiSpeedUp installer barfs with something like this:
---------------------------
Installdelphispeedup105
---------------------------
Cannot register DelphiSpeedUpLoader.bpl.
---------------------------
OK
---------------------------

In this series of PowerShell postings, the below quote by Don Jones from Concentrated Technology is a must:
Proper formatting, including a little whitespace here and there, can make your Windows PowerShell commands a heck of a lot easier to understand.
But please don’t limit this to PowerShell code.
I see too many code at clients, even at conferences and magazine articles that are badly formatted.
Even more important: when you ask or provide for help on a forum or community site: please properly format your code examples. That makes it much easier for your audience (often yourself) to grasp the meaning.
For PowerShell: note that most syntactic elements provide for a very natural line continuation (so you can write really readable code), except for CmdLets, so often you will see { at the end of a line to make the most readable code.

Just a reminder to Self after reading Predefined Conditions in Conditional compilation (Delphi) – RAD Studio.
On iOS, these conditional symbols are defined:
- IOS
- MACOS
- MACOS32
- POSIX
- POSIX32
For the (x86 based) iOS simulator, CPU386 and CPUX86 are defined.
For iOS physical devices, CPUARM is defined.
For OS X and the iOS Simulator, ALIGN_STACK is defined as some parameters (including Extended) require to be aligned on 16-byte boundaries. For explanation, see the Mac OS X Stack Alignment article by Eli Boling, as well as PC_MAPPED_EXCEPTIONS and UNDERSCOREIMPORTNAME (sometimes een PIC).

When writing the Spring4D unit tests for GetTypeSize to include as many TTypeKind values, I came across a few types that either did not compile, or were not supported by TypeInfo. I listed them below as I could not find them in the documentation.
I included a test named Test_EnsureAllTTypeKindsCoveredByCallsTo_Test_GetTypeSize_ that verifies that all TTypeKind values except tkUnknown are covered. So future extensions of TTypeKind will make the tests fail.
As a side issue, I really wanted to know if tkUnknown could be emitted by the compiler. It can sort of, for instance by defining discontiguous enumerations, but are incompatible with TypeInfo as well.
Types that do not compile at all: Read the rest of this entry »

This post lists a lot of links related to the history of Pascal / Object Pascal / Delphi Language / FreePascal / etc.
No mentioning of Pascal should start without Niklaus Wirth. At the time of writing he is still alive, hopefully he still is a the time of publication.
Link clearance.

There are (soon probably “were”) a few very interesting Q&A threads on Stack Overflow in the “Hidden Secrets of” series on Delphi related topics.
I sort of can get (but don’t agree: there is a very good voting system to de-emphasize material that is not useful, but who am I to argue with the minority of “the world is black and white, we just follow the rules” diamondss) that these get closed, but cannot get that very useful material gets deleted for anyone with less than 10-thousand reputation.

@Jeroen & David, I’ve deleted my off-topic comments from here. Could you do the same, please ? I’ve also asked moderators to delete my meta question as it seems the users there are not even humans. Never mind. Stack Overflow is not what it was few years ago as I observe. It’s getting worse. Another piece to this mosaic was running the portuguese version of Stack Overflow ideal for cross posting between the sites.
