关于 进程外 COM 服务器的 生命周期

[hbs_biscuit]

问题是这样的： 我要写一个 音视频的控制器，被网页控制。
由于控制器比较复杂，在 浏览器中生存不太靠谱。
所以我用 ATL 写了一个EXE 的 COM.
主模块 继承于 ATL::CAtlExeModuleT

然后构建了一个对象

lass ATL_NO_VTABLE CSipPhoneControl :
public CComObjectRootEx<CComSingleThreadModel>,
public CComCoClass<CSipPhoneControl, &CLSID_SipPhoneControl>,
public IConnectionPointContainerImpl<CSipPhoneControl>,
public CProxy_ISipPhoneControlEvents<CSipPhoneControl>,
public IDispatchImpl<ISipPhoneControl, &IID_ISipPhoneControl, &LIBID_VISSipPhoneLib, /*wMajor =*/ 1, /*wMinor =*/ 0>,
同时 指定宏 DECLARE_CLASSFACTORY_SINGLETON 做单实例。

在 WEB 中 嵌入一个 activex 作为客户端调用这个对象，目前控制非常好 ，方法调用和接收事件都可以 。

我的问题是： 当客户端都关闭后 我的这个 EXE 的com 实例也就销毁了，exe也就消失了，我有没有什么办法 保持这个COM 实例不销毁 ，需要在这个EXE com中 做哪些操作。

另外处于某些控制需求，可能需要我在这个EXECOM 中 控制关闭这个com 实例，我目前只能先 FIRE 一个事件通知所有的客户端，然后客户端都将连接点断开，并release， 若 某个客户端不release这个com 我就只能干等着，有没有办法，在EXE中硬性都release掉，优雅的关闭这个COM 呢 。

生成COM server。然后开辟run的循环。

Usually, each client/server pair covers an area of COM technology. Here is an overview of the technologies covered by the lessons. Basic Win32 application programming is covered in the APPUTIL, READTUT, EXESKEL, DLLSKEL, and DLLUSER lessons. APPUTIL provides a utility framework for building Win32 applications. It also contains some tools needed for tutorial purposes. READTUT is a very simple EXE application that shows how to link to the APPUTIL static library and call utility functions in it. READTUT also shows how to invoke the COM tutorial Web page reader that is used throughout the sample series. EXESKEL shows a basic Win32 skeleton EXE application built using APPUTIL. DLLSKEL and DLLUSER simularly show a basic Win32 DLL (Dynamic Link Library) skeleton and how to access it from an EXE user application. Basic COM object construction, custom interfaces, and techniques for coding their reuse using aggregation and containment are covered in COMOBJ and COMUSER. The implementation and use of the standard IUnknown interface is covered. The implementation and use of the custom ICar, IUtility, and ICruise interfaces is covered. Basic COM component construction, class factories, component object registration, and techniques for housing COM objects in COM component servers are covered in REGISTER, DLLSERVE, and DLLCLIEN. The implementation and use of the standard IClassFactory interface is covered. COM component Licensing is covered in LICSERVE and LICCLIEN. The implementation and use of the standard IClassFactory2 interface is covered. Out-of-Process local servers and the standard marshaling of custom interfaces are covered in MARSHAL, LOCSERVE, and LOCCLIEN. Explicit self-registration in the standard marshaling DLL is covered in MARSHAL2. The use of the MIDL language to specify custom interfaces is covered. The use of the MIDL compiler to produce proxy/stub marshaling servers is also covered. Apartment model server and client construction are covered in APTSERVE and APTCLIEN. Construction of multiple single-threaded apartments (STAs) in the same process is covered. DCOM (Distributed COM) with custom interfaces operating between client and server across machine boundaries is covered in REMCLIEN. Specifying the remote machine name in the COSERVERINFO structure is covered. Detailed DCOM security issues are not covered. Free-threaded COM components and their access by free-threaded clients are covered in FRESERVE and FRECLIEN. The use of several client worker threads in the multi-threaded apartment (MTA) is covered. The implementation and use of a custom IBall interface is covered. Connectable COM object technology is covered in CONSERVE and CONCLIEN. Event source and sink construction is covered. Implementation and use of the IConnectionPointContainer, IConnectionPoint, IEnumConnectionPoints, and IEnumConnections standard interfaces are covered. The implementation and use of the custom IBall and IBallSink interfaces is covered. Structured storage using COM's compound file technology is covered in STOSERVE and STOCLIEN. A COM-based scribble drawing application is used. Use of the IStorage and IStream standard interfaces is covered. The implementation and use of the custom IPaper and IPaperSink interfaces is covered. Persistent COM objects are covered in PERSERVE, PERTEXT, PERDRAW, and PERCLIEN. IPersistStream is covered in the PERSERVE components. IPersistStreamInit is covered in the PERTEXT components. IPersistStorage is covered in the PERDRAW components. The PERCLIEN client functions these various persistent objects and manages storage for all of them in various substorages and streams within one structured storage compound file. The implementation and use of the custom IPageList, ITextPage, IDrawPage, IPageListSink, ITextPageSink, and IDrawPageSink interfaces is covered. DCOM (Distributed COM) Security is covered in DCDMARSH, DCDSERVE, and DCOMDRAW. The use of CoInitializeSecurity is shown in the DCDSERVE and DCOMDRAW samples. Multiple clients accessing a shared single COM object across machine boundaries is shown in a simple network shared-drawing application. Process and activation security within NT network domains is discussed. Registry AppIDs and their LaunchPermission, AccessPermission, and RunAs named values are discussed. The use of the DCOMCNFG utility is covered. Back to page top © 1995-1998 Microsoft Corporation
