COM (formerly known as OLE) represents Microsoft's "Component Object Model" (Component object models), which is the basis for all ActiveX technologies, including ActiveX controls, automation, and ActiveX documents. But COM also contains more stuff. It is a special specification that the component objects that it develops can be "interoperable" through the specialized features of the operating system. In pra

From: http://blog.163.com/junby2004@126/blog/static/9714233120091105308843/ People familiar with object-oriented programming and network programming must be familiar with ActiveX, Ole, and COM/DCOM concepts, but the relationship between them is still vague to many. The difference between components and objects should be clarified first. A component is a reusable module that consists of a set of processing

Thursday, March 15,200 1 By ish Singh Introduction: Com is sometimes referenced as common object model but Microsoft officially callit Component Object Model. microsoft also developed DCOM as an extension of COM. DCOM was designed with Distributed Computing in perspective. CORBA stands for Common Object Request Broker Architecture and developed by Object Management Group (OMG ).

problem of COM Object running under CLR. First, compare COM Object and. Net object.1. The customer of COM object must manage the life time of COM object by themselves;. Net object is managed by CLR (GC)2. The customer of COM ojbect calls QueryInterface to query whether

The COM component has three basic interface classes: iunknown, iclassfactory, and idispatch.The COM specification specifies that all components and interfaces must be inherited from iunknown. iunknown contains three functions: QueryInterface, addref, and release. These three functions are extremely important, and their order cannot be changed. QueryInterface is used to query other interfaces implemented by

Recently, this registry-free COM technology was used in our work, that is, free registration of COM. The COM component we provide will be used by multiple products, and these products may: Installed on the same machine The COM component used is of different versions. In this way, if you use a common registered

in the "Big talk design mode C + + version-abstract Factory mode", we save the world attempted, leaving little regret, in this article we will give a solution--com component technology, but also pull the factory model in the application of COM component technology.The root cause of the Factory mode violation of the open-closed principle is that the object generation cannot be controlled by the data outside

the object-oriented idea is difficult to adapt to this distributed software model, so the componentized Program design idea has developed rapidly. According to the idea of componentized programming, complex applications are designed into small, single-functional component modules that can run on the same machine, it can also run on different machines. In order to implement such an application, some extremely detailed specifications are required between the build program and the build program.

The problem starts with this: I need to write a COM + to connect to different databases. Some friends might say that you should build a COM + for each database, but not in my system. We are doing an education-assisted system, the user is a school (including school teachers, students, parents), we build a database for each school, these databases are the same structure. Of course, we also have a management d

Introduction to window| Functions COM functions built into PHP4 are quite attractive for us to develop programs in the Win32 environment, but there is still not much relevant technical documentation. This article will deal with MS office Word, Excel, and Adobe Distiller in three examples to illustrate how to use COM functions in PHP. COM technology was presente

People who are familiar with object-oriented programming and network programming must not be unfamiliar with the concepts of ActiveX, OLE, and com/dcom, but what is the relationship between them is rather vague for many people.Between the specific descriptions of their relationships, we will first identify the difference between the component (Component) and the object. A component is a reusable module that is a business object (Rules object) that con

In addition to providing back-compatible,. NET Framework also supports forward compatibility, which is meant to be exposed. NET assembly is possible for COM utilization. Now let's see how we can get COM to leverage. NET assembly. Calling. NET assembly from COM Now let's look at the principle of using. NET assembly from COM
