Project compatibility = No upgrade requiredOver the years, one of the challenges for our customers has been the cost of upgrading the New Visual Studio version. The cost is too high for Visual Studio 2010, especially for Visual C ++ customers who upgraded from Visual Studio in 2008, it is too troublesome to break compiler changes and completely new projects and build systems based on msbuild.In Visual Studio 11, we support compatibility between Visual

In the klayge development edition, some features of C ++ 11 were used for the first time. Currently, two functions are used: nullptr and enum. All these C ++ 11 only codes are put into # ifdef/# endif, and non-C ++ 11 ALTERNATIV
Guidance:This week,The Microsoft build Conference was officially opened in anhaheim, California.. In addition to the latest Windows 8 News, Microsoft also introduced the latest developments in development tools at this Conference: VisualStudio 11 and team Foundation Server 11.

Using CMake for the first time, we searched for a lot of tutorials, including "CMake practice", "CMake Handbook", etc., but there are a few problems with programming under the latest C++11 conditions, you need to experiment many times and search a lot of articles to solve the problem. Here with the Novice diary of the way to tell a cmake how to use the c++11 under the CMake.In general, reading documents dir

Problem
You want to define a built-in function used in eSQL and LINQ queries.
Solution
We want to use the IsNull function in the database, but EF has not released this function for eSQL or LINQ. Suppose we already have a WebProduct entity model, as shown in Figure 11-12

Rvalue reference is one of the most important improvements in the C++11 language core. Rvalue references bring "Move Semantics" ("Transfer Semantics") to C + + and solve the problem of perfect forwarding in template programming (Perfect forwarding). rvalue references enable C + + objects to identify what is (and can be considered) a temporary object, and to do some special processing of a copy of a temporary object, typically by simply passing the own
Erase in the loop:(1) For an associative container, nothing is returned after erase, and subsequent iterators cannot be down, that is, you cannot perform ++it or it--operations. What needs to be done is to it++ the iterator when it is deleted, so that it is OK to go down.(2) For a sequence container, the next iterator is returned after erase, but causes all subsequent iterators to fail, and if you want the loop to continue, save the return value of the iterator and start the iteration here.Regar
A few weeks ago, Dell released the new XPS 11 ultra-polar, which not only carries the latest Intel Haswell processor, but also has a 360-degree flip screen design similar to Lenovo Yoga, which is automatically disabled when the screen flips to the back of the fuselage. At the same time, this 11.6-inch screen resolution of up to 2560*1440 pixels, is undoubtedly the most noteworthy Haswell platform deformation of the present. At the Computex Taipei Comp
Today, I read the related development documents and Sample programs of Windows 8 provided by Microsoft, and found that the expression of a C ++ program is similar to that of tianshu, it turns out to be a new Lambda expression supported by C ++ 0x/11. I have never been too lazy to look at the C ++ 0x/11 instructions and want to study it later, today, I took this opportunity to take a look at the following ne
C++11 is not fresh technology, but for me, the work is not enough (the former club long-time use of gcc3.4.5, although last year rose 4.8.2, but the old module maintenance is still 3.4.5 majority; the new owner uses 4.4.6 and cannot fully support C + + 11, and there is an internal base library has already supported the C++11 STL part of the function), coupled wit
