Book review: Mastering Windows 8 C++ App Development
- 08 August 2013
Disclaimer: I am a Microsoft MVP in Visual C++, so is Pavel Yosifovich, the author of the book. Mastering Windows 8 C++ App Development by Pavel Yosifovich is a new addition to the Windows Store development books. It took me a while to read (304 pages) but is well worth the time from the perspective of a C++ developer. The book obviously went through great lengths to be comprehensive, not only introduced the typical Windows Runtime (WinRT) APIs in a crisp manner but also added a refreshment of C++ 11, the Model View ViewModel (MVVM) pattern, and the Windows Runtime C++ Template Library (WRL). In addition, being a book for C++ developers, the author’s emphasis on performance can be found in several tips and discussions, which is a nice focus for C++ developers. There are also several weaknesses in the book. Introducing WRL before C++/CX may be a poor choice as it is difficult to inspire the reader with laborious code. Also the book could use a few more details on DirectX and some WinRT APIs such as GeoPosition. Nevertheless, the book is an excellent text for the subject and I recommend the book to C++ programmers who want to start developing Windows Store apps and can do research outside of the book.

How to: Migrating a CLR console Visual C++ project to Windows Forms
- 17 December 2012
Note: Windows Forms programming in new development is discouraged by Microsoft at this point as Microsoft wants to make full use of hardware accelerated drawing instead of using the CPU-intensive GDI. But maintaining old Windows Forms code in Visual C++ 2012 is still supported, GDI isn’t going anywhere anytime soon. Visual C++ 2012 removed the Windows Forms project template and I see people scramble to find ways to create a Windows Forms project. There is a walkaround that’s been around for years, that is, to convert a CLR console application to a Windows one, then add forms related code to the project. The basic steps are listed at http://support.microsoft.com/kb/317433, conveniently named “How to suppress the console window for a managed extensions to Visual C++ Windows Forms application”. Yes, the need to convert a C++ console application to windows forms is that old, back all the way back in the managed extensions for C++ days. So what I need to do to add Windows Forms support to a C++/CLI console application? Of course the System.Windows.Forms.dll reference is missing in a new console application, so I need to reference it:
Add the correct interface first in Adding an MFC Class from an ActiveX Control wizard.
- 04 December 2012
In good old times aka VC6, if you want to use an ActiveX in MFC, the Components and Controls Gallery would generate all the properties and methods of an ActiveX and pull dependent types and create wrapper classes for them as well. And it was good. It magically knows the main class of the Windows Media Player ActiveX is CWMPPlayer4 and that GetCurrentMedia method returns CWMPMedia.

What is the difference between int and System::Int32
- 22 November 2010
Some may say identical, at least that’s what the Visual C++ compiler tells you at the first glance when you turn on /oldsyntax public __gc class Class1 { public: void F1(int a){} void F1(System::Int32 a){} //Error 2 error 2535: void Class1::F1(int)’ : member function already defined or declared } Okay, so if I add & to the parameter types I should get the same error right?void F1(int&a){} void F1(System::Int32& a){} Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped Wait, didn’t I get an error just now? You are right, somehow the compiler treat the two types differently when passing by reference. look at the function signatures in MSIL. Int32 is passed by reference as expected

MFC更新Beta版
- 08 January 2008
一个面向Visual C++ 2008的MFC更新测试版已经发布，同时也提供了文档的下载。这个版本包含新的界面的特性，例如Office Ribbon、2003和XP风格,Visual Studio风格和MDI标签。另外，这个版本也包含部分TR1的实现，例如正则表达式、更加丰富的集合和智能指针。 另外，在下载页面居然说这个版本还不支持Visual Studio 2008 Service Pack 1的Beta版，正式版才出来几天SP1的测试版就出来了？

MSDN第9频道又采访了Visual C++类库组的项目经理Nikola Dudar和Sarita Bafna，以及质量控制组的Marina Polishchuk。尽管Visual C++项目组已经转移了工作重点，但是很少人注意到这一点。或许这些采访可以帮助你了解Visual C++项目组的工作。 为什么C++仍旧重要？

How to use Visual C++ with Perl
- 03 November 2005
Microsoft Visual C++ and later do not support perl scripts by default. That is, the Developer Studio does not associate any special significance to perl scripts without being informed otherwise. However, there are several viable options, namely custom build rules, which enable the creation of projects that depend directly upon perl scripts. The remainder of this article discusses the following three methods for adding perl script files to a Visual C++ project:
《转换指南: 将程序从托管扩展C++迁移到C++/CLI》译后
- 17 March 2005
终于把Stan Lippman先生的这篇文章译完了。从去年4月在全球MVP峰会上拿到这篇文章的手稿到现在，差不多一年过去了。虽然当时的Visual Studio 2005还不支持一些语法，但是我和董颖涛对新的C++/CLI语言都很感兴趣，在当时就讨论过翻译的问题。之后我就开始翻译这篇文章，但是进度一直很慢——主要是杂务太多、语言上的困难（尽量避免误解和词不达意的情况，以及斟酌用词的选择）。在1月份完成了全文之后，看到了Sunhui的一篇文章（http://community.csdn.net/expert/Topicview1.asp?id=3834281），觉得附录里面讲到的一些内容或许一些人也有兴趣，所以继续翻译附录的工作，幸好现在是春假，比较有时间，终于在今天完成了。译文目前在http://blog.csdn.net/jiangsheng/archive/2004/10/18/140450.aspx可以访问，希望读者指正。
