About code. Mostly on C++
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 The first thing you’ll notice is that msvcrXX.dll has been replaced by three new DLLs: appcrtXX.dll, desktopcrtXX.dll and vcruntimeXX.ddl (where XX stands for the version number so in this version it’s appcrt140.dll,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
Visual Studio 2012 introduced a new framework for writing debugger visualizers for C++ types that replaced the old autoexp.dat file. The new framework offers xml syntax, better diagnostics, versioning and multiple file support. Visualizers are defined in XML files with extension .natvis. These visualizers are loaded each time the debugger starts. That means if you … 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
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
The C++ REST project provides a modern asynchronous C++ API for cloud-based client-server communication. It is available on codeplex and works with Visual Studio 2010 and 2012, but it is now distributed with Visual Studio 2013. The preview version of VS2013 deploys version 1.0 of the SDK. Since its release a new version of the … Read more
CPtrArray is a nasty MFC container that should not be used. However, if you deal with legacy code you may not have a choice and have to work with it. Unfortunately, the Visual Studio debugger is not able to display its elements, since these are pointers to void and that can be anything. In this … Read more
A WinForms DataGridView control has the ability to automatically generate its columns and populate from a specified data source (which can be a DataSet, a simple list or something else). All you have to do is something like this: var list = new List<Record>() {new Record() {Id = 1, Name = “item 1”, Date = … Read more
