1. How to create COM objects Clients can create COM through the CoCreateInstance function, and must know some basic things about the object before it is created, such as the CLSID of the object or the ProgID of the object. Another object creation method is created by a moniker (moniker), which is the use of object naming and binding techniques (i.e., name technology). 2, the status of the name technology

) Running as CGI COM tags in PHP4 Now let's start with PHP4 COM to instantiate a component that requires the new operator and the object's "OLE program ID": $instance = new COM ("$identifier"); ?> Because COM is a PHP4 reserved word that transmits the identity of this object to a constructor, and now gets an ins

calling CoInitialize will become the main STA, The worker thread may abort at any time, in which case the worker thread aborts the main STA and no longer exists, so you need to call CoInitialize in the main thread to initialize the main STA, even if the main thread does not use any COM components. mta multithreaded suite, all COM components run in the MTA suite of this thread. This

logical combination of a set of objects that share the same set of concurrency and re-entry restrictions. If a thread wants to use com, it must first enter a Suite. COM stipulates that only threads running in the object suite can access the Object.Categories of suites:COM defines two types of suites, STA (single-threaded suite), and MTA (multi-threaded suite).Th

executes within the process of the COM + application itself, while using concurrency to process components. 3. Library applications: Implemented within the process of a client application, loaded within the client application process, using task-based security, with the disadvantage of not supporting remote access and queue components. 4. COM + Pre-installatio

information is stored as resources in the dynamic link library. This function can read resources, write information into the registry, and useWhen regsvr32.exe registers the component, it actually calls the function output by the component. Dllunregisterserver: when a group is no longer used, this group should be capable of self-unloading. regsvr32.exe can call this function to achieve this step.Dllcanunloadnow: The global variable in the COM Service

can connect to an object instance and use the method Attribute. If you want to use the source code of the following example, please refer to my configuration. Windows 98-MS Office 2000 Apache 1.3.9 Windows PHP4.02 Dev (08-20-00) Running as CGI COM mark in PHP4 Now let's get started. to instantiate a component with COM of PHP4, we need the "OLE program identifier" of the new operator and object ": $

, it's all done by the framework.2 "program" is generally in the operation of the operating system directly or indirectlyA "managed program" is a program that requires access to the common language runtime (CLS) to access the operating systemUnmanaged programs do not have direct access to the operating system's programs by accessing the common language runtime (C

__event keyword on the interface declaration to declare the method of the interface as an event. These events are fired when you call the event of this interface as an interface method. The method on the event interface can have 0 or more parameters (all in Parameters). The return type can be void or any integral type.Defining an event handlerIn the event receiver class, you can define event handlers, which are methods that have signatures (return types, calling conventions, and parameters) tha

Create | object in this article, we will discuss the following questions: • Create a simple COM object using C # (using COM's interop attributes). • Access COM from VC + + client software. The client software uses the TypeLibrary (. tlb file). For simplicity and convenience for developers to use and test, we used the Northwind database in the default installation

" to a thread. Like what:Single-threaded Suite (STA): This House (STA) can only accommodate one person (suite thread), and may have multiple computers (COM objects). Of course, this person will only use one computer at a time. People outside the house (other suite threads or free threads) who want to access the computer (COM object) in this House, must make some
