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

People familiar with object-oriented programming and network programming must be familiarActiveX,OleAndCOM/DCOMThese concepts are not unfamiliar, but many people are still vague about the relationship between them. In the relationship between them, we should first clarify the components (Component) And object (Object. A component is a reusable module that consists of a set of processing processes, data encapsulation, and user interfaces (Rules object). The component looks like an object, but d

What is com?The so-called COM (componet object model, Component Object Model) is a specification that describes how to establish dynamically changing components. This SPECIFICATION provides a way to ensure interoperability, some binary and network standards that customers and components should follow. This standard allows communication between any two components without considering whether the operating env

Second, VC for COM programming, you must master what COM theory knowledge I have seen a lot of people learn com, after reading a book on the principle of COM more understand, COM also so much, but just do not know how to program, I have this situation, I have experienced suc

Fortunately, we can use COM components to maximize the functionality of the ASP. You know, anything that can be written in a language such as VB,VC and VJ and other programming languages can be applied to the development of your Web site, which is COM (Component Object model). COM can be used to write objects that can be invoked by ASP. When the programming envir

Recently a collaborative 973 project that needs to call someone else's interface. The other side gave a DLL file and function interface description, and then I looked through the traditional generated dll,loadlibrary to find function pointers, through function pointers to call, failed. Later found that the DLL is not a general DLL but a COM interface, need to register AH and so on. The purpose of COM is to

Use Visual C #. Net to generate an office com external program For the Microsoft Visual Basic. Net version in this article, see 302896. For Microsoft Visual Basic 6.0 in this article, see 238228.

COM programming In-process COM servers (in-process COM server) In-process COM server (in-process COM server) has been introduced briefly before, here, only some need to understand, understand the knowledge points, and then programming may be better; in-process servers are

COM (Component Object Model, Component Object Model) is a binary and network standard created by Microsoft. It is also a component standard that Microsoft has vigorously promoted and widely recognized. In the com standard, the COM object is well encapsulated, and the customer cannot access the implementation details of the object. The only access channel provided

I. BACKGROUND notesIn VS Environment, develop C + + code operation PPT, support the modification of PPT template. This includes modifying text labels, charts, and tables. To meet the requirements of most software-generated PPT reports, create PPT templates manually and modify the template data in the program.Second, the development environment constructionCreate a COM interface for PowerPoint and Excel through the VS2012 Class Wizard; Because you need

First create a COM component, insert a dual interface ITest, and implement the following three methods on this interface:STDMETHODIMP ctest::test (void) //No input/output parameter { //TODO: Add implementation code in this MessageBox (null,l "test", L "test", MB_OK); return S_OK;} STDMETHODIMP Ctest::test1 (BSTR A1) //have a string input parameter { //TODO: Add implementation code in this MessageBox (null,a1,l "test", MB_OK);

one of the principles and implementation of COM COM component is actually a special object system, follow a unified standard, so that each software can access the object in some way, can do component calls. COM is the unified standard-invoking COM components through interfaces. An interface is the only thing that a

If you are an active Server page (ASP) developer, it is believed that you may often use COM objects to create ASP pages. Even when you use it, you ignore that he is a COM object. For example: ADO. The only component with the highest call rate is the ability to extend unlimited functionality to your page. However, the ASP itself is an interpretative script that is not functional enough to

These external programs are called com external programs. This article gradually discusses the Office com external program and describes how to use Microsoft Visual

COM object createdAnd then how to call the COM component. Here is the method for calling the COM Object in C ++. There are generally three methods to create a COM object. You can create an object normally and use the cocreateinstance function. If you create an object in a remote system, use the cocreateinstanceex funct

1, the Linux server configuration switch environmentA, remotely connect to a Linux server over a network or use a Linux server locally, connect a Linux server's COM port to the console port of the switch, and install the Minicom software configuration switch on a Linux server.b, if the minicom is not installed, the Yum installation method is as follows:Yum install-y minicom installs COM serial communicatio

The current project is to develop an add-on for Excel to achieve financial-related business, and after a lot of factors are considered, decide to abandon C # and develop it in C + +. There are two ways to develop Excel add-ins in C + +, one is an Excel add-in XLL, and the other is to use ATL to make COM add-ins. The advantage of the XLL approach is that it is close to the bottom of Excel, executes quickly, and does not need to modify the registry, but

Using WMI to obtain system information procedures As an example of obtaining a native system, the process of obtaining system information is as follows: 1 initialization of the COM library Since the WMI application was written in C + + based on COM technology, the COM library must be initialized, when the call function CoInitializeEx is used to initialize the

The Oracle tutorial you are looking at is that Oracle uses Pl/sql to manipulate COM objects. The Pl/sql is extended by Oracle company to standard SQL, dedicated to programming in Oracle databases, and is a third-generation process programming language. Starting from Oracle8, it provides the process of calling external C language directly from Pl/sql, allowing developers to use PL/SQL for programming modules in C language. Starting with Oracle8i, Java
