DWinProgramming - D WinAPI programming

This is a collection of samples from Charles Petzold's Programming Windows book, translated into the D programming language. It also contains a small collection of other Windows API samples.

See examples.txt for a description of the samples.

This project has been created by Andrej Mitrovic. Project Homepage:

Building Requirements

  • Windows XP or newer.
  • Compiler: DMD v2.065 or GDC 2.065.


Compile the build script:

$ make_build.bat

And then to build all samples via DMD call:

$ build.exe

Alternatively to build all the samples via GDC call:

$ build.exe GDC

Note: Building all samples is quite slow with GDC at the moment.

To build only a single example, CD to its directory and run:

$ ..\..\..\build.exe filename.d (filename being the main file)

Other options are: clean, debug.

Useful Scripts

  • Use dbg.bat to quickly invoke the ddbg debugger on an executable. ('dbg main.exe')
  • Use gdmd.bat to invoke the GDMD perl script. ('gdmd main.d -ofmain.exe')
  • Use where.bat to find out the location of an exe/batch file. ('where dmd')

Optional Tools

  • HTOD: HTOD needs to be in your PATH. It's probably best to put it in the \DMD2\Windows\Bin directory.

  • Microsoft RC compiler and header files. Without these the build script will use precompiled .res files.

    • Unless you have Visual Studio installed, get it from:
    • RC needs to be in your PATH if you want to compile resources. If you have Visual Studio installed, you can use the Visual Studio Command Prompt.

      Note: This is a big download, depending on what you select in the setup. Note: DigitalMars has a resource compiler, but it still requires header files. See the "Using Resources in D" Tutorial in the Links section.

    • Create the RCINCLUDES environment variable and add paths to the header files needed by the RC resource compiler. On an XP system these paths could be: C:\Program Files\Microsoft SDKs\Windows\v7.1\Include C:\Program Files\Microsoft Visual Studio 10.0\VC\include C:\Program Files\Microsoft Visual Studio 10.0\VC\atlmfc\include

      Typically the include paths for resource header files are different on each system, so you will have to adjust these.

      Note: The build script will attempt to find these default paths if you don't have RCINCLUDES already set up. Note: Setting up an environment variable might require you to log off and log on again before the build script can pick up the new changes.

  • The uncrustify executable bundled with UniversalIndentGUI could be outdated compared to the latest Uncrustify version. Please see the Uncrustify homepage in the Links section in this Readme to get the latest binary or to compile from source.

Thanks to the authors of the WindowsAPI translation project:

Big Thanks to Charles Petzold for writing a great Windows API programming book and for allowing me to host these code samples online.


Simen Endsjø tested the project on an x64 Win7 system and found several issues. Leonardo Maffi created a Python script that got rid of stray parens.

Thanks goes out to all contributors.
