Enumerate COM object (IDispatch) methods using ATL?

阅读更多关于 Enumerate COM object (IDispatch) methods using ATL?

问题 Using ATL (VS2008) how can I enumerate the available methods available on a given IDispatch interface ( IDispatch* )? I need to search for a method with a specific name and, once I have the DISPID , invoke the method (I know the parameters the method takes.) Ideally I would like to do this using smart COM pointers ( CComPtr<> ). Is this possible? 回答1: You can't enumerate all the available methods unless the object implements IDispatchEx. However, if you know the name of the method you want to

前段时间，帮人改了个项目，里面明明感觉是MFC，但是却调用C#的类函数，用的都是gcnew指针，凭借着对C#的熟悉，一点一点的实验，终于帮人把程序改好了，但是却不知道到底是什么东西，C#和MFC的混合编程？感觉也不像，现在发现原来是CLR，找了两篇文章，标记一下，便于以后学习。文章和代码需要后续验证。文章1 ATL用于编写COM程序，CLR是.NET的公共语言运行库，MFC是指MFC类库，MFC程序是用这些类库做出的程序，WIN32常规就是不用 MFC，使用API函数编的程序。 MFC、ATL和CLR是VC2005内置的3大库，涵盖了windows的各种开发方法和开发应用。当然关于C++开发的库不止这3个，不过这3个是微软推荐。从编程所处层次而言，WIN32为最底层,其次是MFC.然后是CLR. WIN32 winAPI MFC MFC类库 CLR .net库. WIN32常规就是不用MFC，使用API函数编的程序。 MFC库有很多年的历史了，MFC是基于Windows API 的简单封装。其核心架构基于”Document/View”架构（20年前被认为很潮流的一种概念）和消息流动机制。这个库自从VC6开始到现在都没有多大改动。MFC封装的范围包括GUI，IO，数据库，网络编程等等方面。但是很多系统开发必须的api都没有封装，这样开发者一般都在MFC的基础上自己

问题 Does anyone here have experience with/in developing IE extensions that can share their knowledge? This would include code samples, or links to good ones, or documentation on the process, or anything. I really want to do this, but I\'m hitting a giant wall with lousy documentation, lousy code/example code/lack thereof. Any help/resources you could offer would be greatly appreciated. Specifically, I would like to start with how to get access to/manipulate the DOM from within a IE extension.
