About code. Mostly on C++
Visual Studio 2015 is out and comes with lots of new features and improvements (see details here) but it also surprised me with what I call a demoting of C++ again to a second-class citizen, after some years when it looked like it regained importance at Microsoft. I’m saying Microsoft has demoted C++ because they … Read more
This project has been moved to GitHub. New location: https://github.com/mariusbancila/mfccollectionutilities C++11 has provided support for range-based for loops. They allow iterating over the elements of a range without using an index. std::vector<int> v = {1, 2, 3, 4, 5}; for(auto& e : v) e *= 2; However, if you try the following MFC code you … Read more
A few days ago Bjarne Stroustrup has published a proposal paper (N4174) to the C++ standard committee called Call syntax: x.f(y) vs. f(x,y). The following excerpt from the paper summarizes the proposal: The basic suggestion is to define x.f(y) and f(x,y) to be equivalent. In addition, to increase compatibility and modularity, I suggest we explore … Read more
This article presents a list of good practices for C++ development. Obviously there are many other good practices that one should adhere to and perhaps some of them are more important than the ones in this list. The following list is a personal recommendation and should be taken as is. Thou shalt follow the Rule … Read more
Visual Studio “14” CTP ships with a refactored C Runtime. The first thing you’ll notice is that msvcrXX.dll has been replaced by three new DLLs: appcrtXX.dll, desktopcrtXX.dll and vcruntimeXX.ddl (where XX stands for the version number so in this version it’s appcrt140.dll, desktopcrt140.dll and vcruntime140.dll). You can see in this image that both desktopcrt140.dll and … Read more
In WPF, Silverlight and Windows Phone it is possible to render a visual object into a bitmap using the RenderTargetBitmap. This functionality, that I find pretty basic, was not available for Windows Store applications. Fortunately, Windows 8.1 provides that functionality for Windows Store applications too, through the same RenderTargetBitmap class. There are some limitations though: … Read more
A friend of mine recently proposed the following problem on twitter: Given f y z =108 – (815 – 1500/z)/y, x0 = 4, x1 = 4.25 and xN+1 = f xN xN-1 then what is x80? Note: This might not be as easy as it looks — Mårten Rånge (@marten_range) October 19, 2013 I didn’t … Read more
The larger a VC++ project is (or any project for that matter) the more time it takes to build. If you have solutions with many large projects the build times could get into your way. Starting a rebuild and going to lunch was a common scenario for me, as building took 20-25 minutes. Of course, … Read more
This project has been moved to GitHub. New location: https://github.com/mariusbancila/cppconlib Many years ago I published on my blog a helper class for working with the Windows console that was wrapping the Windows console API. Looking back at it I realized it was a pretty naive implementation. So I decided to start a new and make … Read more
UPDATE: for an updated version of this demo, using C++ REST SDK 2.10 see this blog post. In my previous post I shown how you can build a C++ application with the C++ REST SDK that fetches search results from a search engine. In this post, I will go a step further and develop a … Read more
