Somewhere in the drafts was a note to refer to an old Chris Bensen blog post on the Embarcadero server: blogs.embarcadero.com/cbensen/2005/12/07/22388
Alas, a lot of Embarcadero stuff is gone, some because of Idera not caring, others because as of Codegear, the team never was good at keeping infrastructure alive, nor cater for proper archiging at the Wayback Machine.
Luckily, the Borland days were different, as I found by browsing web.archive.org/web//http://blogs.borland.com/: almost 10k archived pages!
Searching for cbensen or 22388 then got me the actual post [Wayback/Archive] Delphi 2006 Hidden COM Registry Entries (the last link is dead, the others not indexed by search engines) and quoted below while adding some formatting: Read the rest of this entry »

When accessing the VCL from multiple threads at the same time: adopted from …\DEMOS\THREADS\THRDDEMO.DPR
Great question a while ago:
[WayBack] “Don’t access VCL from a background thread” – how to demo that? – Primož Gabrijelčič – Google+
For me, the ultimate way why not to access the VCL from a background thread is the precursor of the official threads demo that ships from Delphi 2 to Delphi XE6 in ...DEMOS\THREADS\THRDDEMO.DPR. where you’d think the thread isolation would be in ...DEMOS\THREADS\ThSort.pas but actually is in ...DEMOS\THREADS\SortThds.pas.
The first public showing of that demo did not include main thread protection. It originates from a session at the the 1995 Borland Developers Conference where Ray Konopka showed the below code from Bob Ainsbury.
That session reminded why this joke [WayBack] Via the EKON20 sessions… – Jeroen Wiert Pluimers – Google+ was so funny: “When Ray Konopka enters the room you have a Raize condition.“.
The question above also made me find back this reference to BorCon95 in San Diego:

For a very long time I’ve discouraged people from using non-ASCII characters in identifiers. It still holds.
In the past, transliterations messed things up. Even with increased support for Unicode, tools still screw non-ASCII characters up.
Delphi is not alone in this (the most important one is the DFM view as text support), see this report: [RSP-16767] Viewing a form as text fails with non ascii control or event names – Embarcadero Technologies (you need an account for this, but the report is visible for anyone):
Viewing a form as text fails with non ascii control or event names Comment
Steps:
- create a new VCL forms application
- drop a label onto the form
- change the name of that label to lblÜberfall (note the U-umlaut)
- switch to view as text
- exp: DFM content shown as text
- act: first line is shown incorrectly (see screenhsot)

As a by-effect, this article seems to one of the few that shows where Delphi uses the .dres file extension introduced around Delphi XE.
Recently I had to play some notification sounds in a Windows Delphi application where the application deployment should be as easy as possible: preferable copying the EXE around.
Playing a sound file seems easy, especially if it is a [WayBack] WAV file: just use the [WayBack] PlaySound or the (older) [WayBack] sndPlaySound API functions.
But if you start searching on the internet, you see lots of curious implementations for playing WAV resources through sndPlaySound.
The actual implementation is really really easy though, just make sure you follow the steps right and nothing can go wrong.
[WayBack] The full source code is on my BeSharp.net repository, here is how to to it step by step:
The steps depend on the MMSystem unit, so most of the code translates back to [WayBack] Turbo Pascal for Windows (yes, the 16-bit Pascal days when the MMSystem unit was introduced) with the exception of the SND_SENTRY flag.
The thing that more recent Delphi versions made a lot easier is embedding WAV files as WAVE resources, more on that further on. Read the rest of this entry »

At the end of April 2014, Roman Yankovsky started a nice [Wayback] discussion on Google+ trying to get upvotes for [Wayback] QualityCentral Report #: 124402: Compiler bug when comparing chars.
His report basically comes down to that when using Ansi character literals like #255, the compiler treats them as single-byte encoded characters in the current code page of your Windows context, translates them to Unicode, then processes them.
The QC report has been dismissed as “Test Case Error” (within 15 minutes of stating “need more info”) by one of the compiler engineers, directing to the [Wayback] UsingCharacterLiterals section of Delphi in a Unicode World Part III: Unicodifying Your Code where – heaven forbid – they suggest to replace #128 with the Euro-Sign literal.
I disagree, as the issue happens without any hint or warning whatsoever, and causes code that compiles fine in Delphi <= 2007 to fail in subtle ways on Delphi >= 2009.
The compiler should issue a hint or warning when you potentially can screw up. It doesn’t. Not here.
Quite a few knowledgeable Delphi people got involved in the discussion:

Every now and then you want to know what units your project is made of. Not just the units require to build your project, but actually the ones ending up in the executable (i.e. not removed by the compiler or linker).
I had long forgotten that Chris Hesik [WayBack] wrote in debugging – How can I find all the units in my Delphi app? – Stack Overflow [WayBack]:
you can have the Delphi compiler show you a list of used .dcus by passing –depends when you compile a project. It will output a .d file with a list of the .dcus (and .dcps) that were required.
This reminded me of that: The –depends option is supposed to work with the Delphi compiler, and it outputs a .d file. Does it still work in Berlin, and where is the file supposed to be output to? – David Nottage – Google+ [WayBack]
In the mean time, I wrote a batch file that parses the .MAP file to see which units actually made it into your .EXE [WayBack] which works only for Widows executables (as I hardly do cross-platform Delphi development).
Uwe Schuster [WayBack] reported the IDE won’t pass on the –depends switch in Delphi XE and up (version 15.0.3953.35171) [WayBack] which means you need to pass this from the command-line.
Ondrej Kelle (G+/SO) pointed out that:
msbuild hello.dproj /property:DCC_OutputDependencies=true
- It does work from the IDE if you check “use MSBuild externally”
The msbuild property setting is available in at least Delphi/C++Builder versions 2007 and 2010..Berlin as it is in CodeGear.Cpp.Targets and CodeGear.Delphi.Targets/RTL.Build.targets for BDS versions 5, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 and 18. It might be available in versions 2005/2006/2009 as well but I don’t have these lying around any more.

A few weeks ago in When you get “TfsScript.Execute” throwing a “Unregistered version of FastScript.” I wrote about “a process that explains any modules in the MAP file not resulting in DCU files”.
The below batch file aids in that process.
It takes a MAP file from your Delphi compiled executable that has debug information in text format which means you need to set your project linker options to generate detailed MAP files.
The Map Debug File (*.map) – RAD Studio documentation hasn’t much information but points to Detailed-Segments Map File – RAD Studio which has a bit more. Neither contain information on Delphi units as they focus too much on the C++ side of things. Then there is a tiny bit information in Understanding Delphi MAP File – Stack Overflow.
So I did some spelunking and came up with this batch-file which will likely work back until about the Delphi 7 era:

Something to remember: Delphi To Go: Include resource files in your Delphi build process
Note it’s not enough to add a line like this to your .dpr file:
{$R 'New1.res' 'New1.rc'}
The resources actually needs to be part of your .dproj file (which basically is an XML msbuild file adhering to the MSBuild Project File Schema Reference).
That way, the BrccCompile target in $(BDS)\bin\CodeGear.Delphi.Targets will automatically pick it up during build.
I just checked and these target files support BrccCompile:
...\Embarcadero\RAD Studio\7.0\bin\CodeGear.Delphi.Targets ...\Embarcadero\RAD Studio\8.0\bin\CodeGear.Delphi.Targets ...\Embarcadero\RAD Studio\9.0\bin\CodeGear.Delphi.Targets ...\Embarcadero\RAD Studio\10.0\bin\CodeGear.Delphi.Targets...\Embarcadero\RAD Studio\11.0\bin\CodeGear.Delphi.Targets...\Embarcadero\RAD Studio\12.0\bin\CodeGear.Delphi.Targets...\Embarcadero\Appmethod\13.0\bin\CodeGear.Delphi.Targets...\Embarcadero\Studio\14.0\bin\CodeGear.Delphi.Targets ...\Embarcadero\Studio\15.0\bin\CodeGear.Delphi.Targets ...\Embarcadero\Studio\16.0\bin\CodeGear.Delphi.Targets ...\Embarcadero\Studio\17.0\bin\CodeGear.Delphi.Targets ...\Embarcadero\Studio\18.0\bin\CodeGear.Delphi.Targets
Which means it’s available as of Delphi 2007 until at least Delphi 10.1 Berlin and might even work in Delphi 2006
It could be a little bit flakey in Delphi 2007 (I’ve had many msbuild issues there) but more recent versions should be fine.
