It's not like an armchair, and now has the ability to implement real-world scenarios, and one of the best examples is porting Quake II to the. NET framework platform, and Visual C + + 2005 expands this functionality.In the local an

Of course, not all functions correspond to the full Community Content section. But some give some constant values, some give some struct definitions, in short, this part of content still has reference value. Note: MSDN installed on the local machine does

ComRegisterFunction property and the ComUnregisterFunction attribute, respectively. When COM assemblies are registered as COM interop, Registerfunction is called.

This technology enables developers to reuse existing managed or unmanaged builds and, depending on their needs, weighs the simplicity of managed code and the flexibility of unmanaged code, choosing a programming language that is appropriate for its own reality, without having to think too much about the language in which the reusable component is developed.
