PrefaceSince Microsoft announced the COM technology for the first time in 1993, the development model on the Windows platform has undergone great changes. A series of software componentization technologies based on COM have brought Windows programming into the componentization era. Until now, COM technology is still thriving, and a large number of components and

First, create COM components with VC1, VC new Project, ATL project, enter the 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 is completed, the VC will automatically generate a series of programs. 3. Switch to Class View, right-click on the Comtest key, add Class, select ATL Simple Object, 4. Come to t

SQL Server's T-SQL programming language is powerful in data storage and recovery, but is less functional in terms of interacting with systems outside of the SQL Server database. However, we can overcome this limitation with SQL Server's built-in COM automation environment, which enables users to automate COM objects in stored procedures. With 7 extended stored procedures in SQL Server 7.0 and SQL Server 6.

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

The component object model com is composed of Execution Code published in the form of Win32 DLL or EXE. Com is composed of some objects and object interfaces. In COM, interfaces provide object operation mechanisms. Interfaces are composed of one or more related methods, attributes, and events. Here we develop a simple but fully functional

DeveloperI often want to talk about Microsoft's future strategies in the following aspects: COM, Microsoft Transaction Service (MTS), and its JIT engine and Object Buffer (ObjectPooling ),Microsoft Message Queue (MSMQ) and DCOM. What is the relationship between websites, application servers, ASP, and component integration? Since everyone is clamoring for answers, let's solve the problem once.These problems exist. First, let me explain the issues relat

If the COM + verification fails, there may be two reasons:1. the COM + service has not been started, or the COM + component itself has an error. The solution is to reinstall COM + (install/uninstall-> Windows Components. Do not change anything. Go to the next step, and then enable the

Com example (3) -- Component code This article focuses on this series of articles. The interfaces previously designed are only auxiliary, and have nothing to do with the com thread model. Because the imodule and imodulesite interfaces implemented by the customer and components are packaged with interface transmission, the interface packaging function of MFC is used for implementation. Therefore, all inter

Lifetime of processing COM objects When an object is created, the system allocates the required memory resources. When the object is no longer needed, the object should be destroyed so that the system can use the memory resources for other purposes. In C ++, you can use new and delete to directly control the lifetime of an object. However, the COM object cannot be directly created or destroyed. The reason i
