Visual Java is a network-centric programming language, and many tasks that are difficult to accomplish with ASP scripts can be easily implemented in Java. At the same time, the best way to extend ASP applications is to join COM components. So, can you use Java to develop components for ASP? This paper illustrates the specific process of developing COM components in Visual J + + environment through examples.

. NET technology is the next-generation platform technology that Microsoft vigorously promotes. Since the formal release of. NET Technical Architecture Beta2, this technology has gradually become mature and stable. According to Microsoft's platform system occupancy rate, we can easily imagine that in the next year or two. NET technology is bound to become a mainstream technology platform, and the most important premise for a new technology platform to develop rapidly is: he will not abandon the

Window|word Using the PHP4 COM functions with MS Excel As for the Word example above, study the code and the help from the Visual Basic Editor objectbrowser for Excel. #Set the workbook to use and its sheet. In the example we use a spreadsheet that #comes with the Excel installation Called:solvsamp. Xls $workbook = "C:\Program Files\Microsoft Office\office\samples\solvsamp. XLS "; $sheet = "Quick Tour"; #Instantiate the Spreadsheet component. $ex =

I. Create COM components with VC 1, VC new Project-> ATL project, enter name Comtest,comtest will be the name of the COM component. 2, to the ATL Project Wizard, do not need to change, complete the wizard. After the wizard completes, VC will automatically generate a series of programs. 3. Switch to Class View, right-click on

This article supporting source code First, the preface My COM component runs with a window, and when the user double-clicks the window, I need to notify the caller; My COM component downloads a file on the network in a threaded way, and when I finish the task, I need to notify the caller; My COM component completes a clock function, and when the scheduled tim

　　1. Defining interfaces COM is called by an external application by throwing an interface, and each interface, component has a GUID, and developing COM components in. NET is no exception. [Guid ("0bb13346-7e9d-4aba-9ff2-862e0105489a")] public interface Imyservice { Defines an interface method or attribute, each of which has a DispID property for use by VBScript, etc. [DispId (1)] void Method1 (args

What is an interface? When it comes to COM, you have to say interface; In the process of COM development, it can be said that I have been dealing with a variety of interfaces. What's the interface? For COM, an interface is a memory structure that contains an array of function pointers, each containing an address of a function implemented by the component, so for

As the saying goes, the rainbow after the storm, but after the financial turmoil, the rainbow in all walks of life need their own to create. In the economic stability but lack of growth momentum of the situation, each industry is a surprise, want to in the post-crisis era to create a better future for themselves, so as to keep pace with the times to maintain steady growth. In the face of such an economic environment, the domain name industry has also been frequent moves, set off a wave of waves,

Part 1 What is com and how to use com Preface: The purpose of this article is to provide a programming guide for programmers who have just come into contact with COM and help them understand the basic concepts of COM. The content includes the com standard introduction, impor

Software reuse is the goal pursued by the industry. People always hope to "Assemble" applications as they build blocks, and component objects act as building blocks. The so-called component object is actually a predefined service or interface that can complete certain functions. The question is, how do these component objects coexist with applications and other component objects and communicate and interact with each other? So what should I do? Standards, allowing these component objects to work

Com is the abbreviation of Component Object Model. What kind of software products do users need? This is a multi-choice question, but it is highly efficient and robust. How can a software developer meet users' needs? Ensure that the backward compatibility with previous versions is not damaged during application upgrade. System services must be extended without a specific operating system. Object-orientedProgramDesign is obviously a revolution

Com is the abbreviation of Component Object Model. What kind of software products do users need? This is a multi-choice question, but it is highly efficient and robust.

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

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

Details about com single-threaded suites 1 Introduction Advanced com projects often need to pass objects across threads to call these object methods in different threads to stimulate their events. The following article is intended for junior com developers who have basic com knowledge (such as understanding the iunkown
