C++ is the language of selection for millions of purposes and thousands of strains of code. With C++/CLI, builders can combine latest C++ code into the .NET platform with out rewriting their purposes. This booklet explores the C++/CLI syntax, teaches tips to combine local C++ and controlled .NET code, and indicates easy methods to combine C++ with home windows kinds, WPF (Avalon), and WCF (Indigo).

think taking a C++-based software you have been utilizing for a decade and giving it a snazzy new interface utilizing home windows Presentation origin. How approximately making your previous company purposes consult your new ones utilizing home windows communique origin. C++/CLI makes this--and more--possible. C++/CLI in Action indicates you ways to bridge the space among your latest C++ code and the .NET platform. C++/CLI in Action can assist you if:

  • You're hesitant emigrate to .NET since it potential rewriting code in C# or VB.
  • You have major C++ services that you really want to leverage within the .NET.
  • You merely have to use items of the .NET framework, equivalent to home windows varieties or internet services.

there isn't any fluff right here. Designed for readers who already comprehend C++, this ebook starts off via educating the original elements of the C++/CLI language. After a brief travel throughout the fundamentals, readers paintings via examples of integrating commonplace C++ into the .NET-based purposes and construction courses that blend C++ and .NET code for max functionality and efficiency.

.NET 2.0 Interoperability Recipes: A Problem-Solution Approach

. web represents a brand new and more desirable method of constructing software program for the home windows platform. Given the opportunity, youТd most likely rewrite your whole present code within the more moderen controlled code setting that . internet presents. however it is hard or most unlikely to throw out all latest legacy code and begin over while a brand new know-how arrives.

New dynamic languages like IronPython have gotten more and more renowned as builders stream clear of statically-compiled purposes. ASP. internet, Microsoft’s renowned net platform, can now aid builders losing in those dynamic runtimes, beginning up the platform to a large choice of builders and programmers who haven’t up previously been capable of use Microsoft applied sciences.

NET; and you can write managed c and native code b within the same application. NET Framework BCL class that belongs to the System namespace (hence the using namespace declaration on top), and WriteLine is a static method of the Console class. 1 uses native data types like TCHAR and DWORD as well as managed data types like String. Similarly, it uses a native Win32 API call (GetUserName) as well as a managed class (System::Console). The best part is that you do all this in a single application (within a single function, in this case).

5 Instantiating CLI classes In this section, you’ll see how CLI classes are instantiated using the gcnew operator. You’ll also learn how constructors, copy constructors, and assignment operators work with managed types. Although the basic concepts remain the same, the nature of the CLI imposes some behavioral differences in the way constructors and assignment operators work; when you start writing managed classes and libraries, it’s important that you understand those differences. Don’t worry about it, though.

N* pN = new N(); R* pR = new R(); The two calls to new (shown in bold) do completely different things. The new call on the native class N results in the C++ new operator being called, whereas the new call on the managed class R is compiled into the MSIL newobj instruction. The native object is allocated on the C++ heap, but the managed object is allocated on the garbage-collected CLR heap, which has the side implication that the memory address for the object may change every time there is a garbage-collection cycle or a heap-compaction operation.
