Do not use non-ASCII characters as identifiers – not all your tools support them well enough

Posted by jpluimers on 2018/04/05

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:

  1. create a new VCL forms application
  2. drop a label onto the form
  3. change the name of that label to lblÜberfall (note the U-umlaut)
  4. switch to view as text
  • exp: DFM content shown as text
  • act: first line is shown incorrectly (see screenhsot)

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

A Delphi Wizard that adds a menu item so the Delphi Icon will change into the icon of the currently loaded project.

Can be useful if you have many Delphi instances open.

Delphi 2009 syntax; not official, but a great start and complement to DelphiAST

Posted by jpluimers on 2018/01/30

A while ago, I found out that [WayBackToon Krijthe made a [Archive.isDelphi 2009 syntax sample which is a great complement to the DelphiAST parser given that Borland/CodeGear/Embarcadero/Idera never published one in the 22+years that Delphi is alive.

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 [WayBackWAV 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 »

Getting rid of [dcc32 Warning] W1029 Duplicate constructor ‘ClassName.ConstructorName’ with identical parameters will be inacessible from C++

Posted by jpluimers on 2017/11/30

Note that the below solution works for any project raising the W1029 warning (not just from projects using Delphi Mocks) like

[dcc32 Warning] W1029 Duplicate constructor 'ClassName.ConstructorName' with identical parameters will be inacessible from C++

From my original text at [WayBackGet rid of W1029 warning in Delphi compile mode · Issue #106 · VSoftTechnologies/Delphi-Mocks · GitHub:

By default the compiler will emit warnings like these for projects when using either of the Delphi.Mocks.Behavior or Delphi.Mocks.Expectation directly or indirectly:

[dcc32 Warning] W1029 Duplicate constructor 'TExpectation.CreateOnceWhen' with identical parameters will be inacessible from C++

They’re harmless as DUnitX doesn’t support C++. This particular warning type cannot be disabled on the unit or source line level which means you have to disable it on the project level by either:

  1. adding {$WARN DUPLICATE_CTOR_DTOR OFF} anywhere to your .dpr project file
  2. modifying the the Project Options for your project (easiest is in the All configurations - All platforms target):
    1. follow the path Delphi Compiler, Hints and Warnings in the treeview on the left
    2. expand the Output warnings node in the listview on the right
    3. set Duplicate constructor/destructor with identical parameters will be inacessible from C++ to Error

A screenshot of the second option is below.

Note that the spelling mistake in Duplicate constructor/destructor with identical parameters will be inacessible from C++ is how it is in the IDE, but that as Google search string it will give limited results, so here are some back-ground references:
