• What's the best software development conventions document you have seen?

  - by Pavel Radzivilovsky

  Google C++ development conventions outlaw exceptions, RAII, RTTI and bans the default parameter in parseInt(number, radix=10). Qt API style guide is brilliant, but only covers interfaces. The Robert C. Martin series Clean Code has M104 galaxy on the cover, but it is 462 pages long and based on Java, with no simple "do this" digest. Assuming that it is important to synchronize style and best practices across the organization, what is the smartest, most pleasant and useful conventions document you have worked with?

• How to export C++ function as a dll that throws exception?

  - by ShaChris23

  When I try to export the following function as a dll: extern "C" __declspec(dllexport) void some_func() { throw std::runtime_error("test throwing exception"); } Visual C++ 2008 gives me the following warning: 1>.\SampleTrainer.cpp(11) : warning C4297: 'some_func' : function assumed not to throw an exception but does 1> The function is extern "C" and /EHc was specified I need to extern "C" because I use Qt QLibrary to load the dll and resolve the function name. Without extern "C" it can't find the some_func() function.

• Cross platform GUI Programming with D

  - by Adam Hawes

  I want to start programming with D. I have a simple application in mind that needs a GUI but I want to make sure it's portable to Linux/Windows/Mac equally well and with minimal (no) change for each platform. wxD is looking like the contender of choice because I know the wx toolkit already. I see fltk4d as a contender and a (unfinished) wrapper around Qt. Are there any other truly cross platform GUI toolkits for D that will go where I want with little effort and what would the the toolkit of choice for people here?

• Developing multiple user interfaces for an application

  - by denizkocak

  I want to develop an application which has a graphical user interface that could be developed by using different widget toolkits. For example I want to use Qt, GTK+ or even ncurses as a building block for my user interface for the same application. Moreover users could choose which GUI implementation will be used during the next startup of the application without recompiling it first. I wonder what are possible design strategies and design patterns used in the implementation of this design?
