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.
Today I went to SQL Server 2005 and installed it for research. The installation process was not very smooth, mainly due to COM + errors. I searched the internet and solved the problem as follows: The installation is successful as follows. Warning for COM + directory problems during sql2005 Installation The installation of sql2005 failed. I thought the problem was caused by the
1.COM Technology Overview COM represents the Component Object model, the software development technology that Microsoft promotes. The application software developed by COM specification has the powerful function, mainly has the following several points: COM is a binary programming specification that allows you to wri
COM + was already generated as early as the window2000 was released and integrated into the operating system, The runtime is in the form of a service. COM + adds a series of MTS (a system service that Used to manage persistent data in a database and also to handle persistent message queues and file systems in transactions Service 1, transaction services: It ensures the integrity of the data in the distribut

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
When I was working on a project a while ago, I encountered the call and use of the COM component. At that time, I had a good research, so I had to get through the intermediate link. Now I wrote it to help you, there are four types: 1. In vs2005, C # compiles a DLL and calls it using C ++. 2. Use vc6.0 to call the COM component written in C # In vs2005 3. Compile COM

The example should be taken to the original article link below. :) Http://dev.csdn.net/Develop/article/article/25/25203.shtm 3. Create a COM component manually1. From Project Creation to registrationIn this process, we will complete three steps: Create the DLL entry function, define the interface file, and implement the registration function.1
Iis Microsoft has tightly integrated the capabilities of IIS and COM +, which makes it very easy to leverage transactional applications in the process of programming the transaction Web page. There are many different ways to integrate the transaction characteristics of COM + and IIS, including the following:? Transactional ASP.? The ObjectContext in ASP.? Transactional events.Developers can use one or more
Method and property names of objects that enumerate COM objects in. Net Author:zee Well, I used to ask this question, no one said, or do it yourself better. Generally, when a COM object is provided, it usually provides a type library in which all the method names, parameter names, property names, and so on of the COM object are defined. All we have to do is ta

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

NET, or C #. For example, Visual Basic.
