如何将应用程序作为COM服务器或独立应用程序执行 [英] How to the Application is executing as COM srever or Standalone app

问题描述

我有一个可以作为独立服务器或com服务器执行的应用程序.现在，在应用程序内部有没有办法知道当前实例是否作为独立应用程序或COM服务器运行.

如果应用程序/服务器是使用CWinApp编写的，则可以调用ParseCommandLine方法，如果m_bRunAutomated是服务器

IUnknown的内部QueryInterface怎么样?如果它的计数为2，则说明它是COM服务器-但要确保它已释放.如果遇到未初始化COM之类的错误，则不是这样.

Hi,
I have an application which can be executed as a standalone or a com server.Now, is there any way, inside application to know wether the current instance is running as standalone application or COM server.

解决方案

if the app/server is written using CWinApp, you could call the ParseCommandLine method, and m_bRunAutomated will be set if it''s a server

How about Internal QueryInterface for IUnknown? If it works with a count of, say, 2 then its a COM server - but make sure its released. If you get an error like COM not initialised, it''s not.
