Compile FreeCAD on Windows[Email protected]1.IntroductionFreecad is a parametric three-dimensional modeling software, mainly used for arbitrary size of the actual model design. Parametric modeling allows you to easily modify your design by modifying the relevant parameters. FREECAD is open source software and provides a convenient way to customize and also provides scripts to expand functionality to suit yo
Freecad is an open-source CAD software. Although its functions are not perfect yet, it demonstrates how to build a complete CAD System-cross-platform.
I have also studied how to build a CAD System in Windows to imitate the software that I am working on, but it involves MFC, VBA, and COM. Although I have always felt that the behaviors that use Microsoft's technologies and advocate Mac and Linux are very em
Original: Http://www.codeproject.com/Articles/633/Introduction-to-COM-What-It-Is-and-How-to-Use-ItThe purpose of this article is to provide programming guidance to programmers who have just contacted COM and to help them understand the basic concepts of COM. The content includes a description of the COM specification ,
COM objects are encapsulated entities that provide services to users. This should be similar to the Class Object in C ++. But sometimes the COM object is treated as the class that provides services. The COM Object also encapsulates the data and provides interfaces. But there are some differences with the class. The data in the class can be declared as public, and

1, COM +
Because of historical reasons, COM, DCOM and MTS are not very harmonious with each other, it is difficult to form a unified whole. COM + has effectively unified these three, forming a new, powerful component architecture.
COM + is not a new version of COM, but a n

All the best programmers do their best to make their written programs more reusable, because it allows you to quickly write more robust and scalable programs.
There are two choices to make code reusable:
1. White box: The simplest one is to copy your program to another file.
2. Black box: It involves connecting a compiled piece of the program. So the compiled black box class library that the client can invoke is called a component.
. NET also provides dev
Part of this section requires the reader to be familiar with the message invocation principle of COM, and the principle of this is as shown in Mr. Yang's column.

The encapsulation characteristics of COM objects are very thorough, all object state information must be accessible through an interface, while COM polymorphism is fully represented by the interface, and
Yesterday saw the first chapter of "com Essence", "com is a better C + +", feel it is necessary to do some notes, so organized into this article, I believe you deserve to have.The main content of this article is: A class faststring that implements the fast lookup function, which slowly evolves into a COM component after a small requirement. Class Faststring imple

Because COM originated in the Microsoft Windows platform, the COM implementation part (that is, the COM library) uses some of the features of the Windows system directly, such as the system registry, the dynamic Connection library, and so on

felt like I was playing jigsaw puzzles. Beginning with a programming language, the system eventually includes C, C + +, Java, SDK, MFC, VxD, Win32 OS, multithreading, C + + STL, Internet Protocol .... I looked at this puzzle and felt that all the changes in the world were almost in my hands. No matter what new things are being exhibited to the language, what application the framework, or what the new driver model, the new protocol, I feel that because I have mastered the basic knowledge, I have
I. In-process components and out-of-process Components
As mentioned above, COM components support both in-process components and out-of-process components. The advantage of in-process components is fast and convenient. However, if any component crashes, the main process will crash. Components outside the process are slow but stable. If a component crashes somewhere, at most there is no result and the main process will not crash (for example, if the
For beginners, COM is not a very clear definition. It represents both a component specification and an implementation. In short, COM is a component model at the language layer, because different development environments often need to cooperate with each other to complete a certain function, thus promoting the emergence of COM.
