delphi – Is it possible to define {$IFDEF} for more than one directive at once? – Stack Overflow

Posted by jpluimers on 2021/06/24

[WayBack] delphi – Is it possible to define {$IFDEF} for more than one directive at once? – Stack Overflow:

  • use the {$IF Defined(xxx)} directive which allows boolean expressions like:
    • {$IF Defined(xxx) OR Defined(yyy)}
    • {$IF Defined(xxx) AND Defined(yyy)}
    • {$IF NOT Defined(zzz)}
  • it has been in Delphi since Delphi 6 (see [WayBack] conditional statements – Why {$IFDEF MSWINDOWS} is replaced with {$IF defined(MSWINDOWS)} in Delphi XE5? – Stack Overflow and many other references).
  • [WayBack] IF directive (Delphi)
    Type
    Conditional compilation
    Syntax
    {$IF expression}

    Compiles the Delphi source code that follows it if expression is true. expression must conform to Delphi syntax and return a Boolean value; it may contain declared constants, constant expressions, and the functions Defined and Declared.

“Don’t access VCL from a background thread” – how to demo that?

Posted by jpluimers on 2018/07/11

When accessing the VCL from multiple threads at the same time: adopted from ...\DEMOS\THREADS\THRDDEMO.DPR

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:

Wizard to change Delphi Icon so it used the Projects’ Icon

Delphi: playing Chimes.wav as an external file or embedded WAVE resource in Delphi XE5.

Posted by jpluimers on 2018/01/10

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 »
