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 »

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:

Back in the .NET days, Delphi had an FINITEFLOAT compile option that came without a single-character shortcut.
It was about the handling of infinite float and other special float values in cases like overflow and underflow (including +Inf, -Inf and [Wayback] NaN).
At first – in the [Wayback] Delphi 8 (Octane) era of which few people want to be reminded off – it was the [Wayback] undocumented counterpart of the [Wayback] 8087 exception mask in x86 mode. Hallvard Vassbotn wrote an article about it and Chee Wee Chua documented it before it got documented in Delphi 2009 (that coincidentally dropped .NET support in the compiler – go figure):
Whereas the native Delphi compilers had exceptions turned on, Microsoft compilers (including .NET) had them turned off, hence the compiler option.
Like most new Delphi features in this century, FINITEFLOAT didn’t come without quirks. Often these are fleshed out in 2-3 product releases, but this one wasn’t:
The FINITEFLOAT compile option didn’t have a single-character shortcut. This made it impossible to use the {$IFOPT ...} construct as IFOPT only works for single-character compiler options.
Which means you get questions like [Wayback] Why doesn’t {$ifopt FINITEFLOAT ON} compile? – Stack Overflow (I actually got into writing this article because I found a {$DEFINE FINFINITEFLOAT_ENABLED} in some pretty old code) and compiler enhancement requests like [WayBack] QualityCentral – Please enhance the IFOPT directive for long switch names. It’s easier to read (which will likely never bee fixed).
For completeness some more information about exception masks in the native compiler:
- In the past you could only set the exception mask as part of the full control word using [Wayback] Set8087CW, nowadays you can use [Wayback] SetExceptionMask.
- Next to a precision mask, there are five exception masks you can set, see for instance this table from the [Wayback] Simply FPU Chap.1 Control Word section:
PM (bit 5) or Precision Mask
UM (bit 4) or Underflow Mask
OM (bit 3) or Overflow Mask
ZM (bit 2) or Zero divide Mask
DM (bit 1) or Denormalized operand Mask
IM (bit 0) or Invalid operation Mask
