Description: 介绍两种方法来写自动化(IDispatch)接口的组件程序，一是用 MFC 方式编写“纯粹”的 IDispatch 接口；二是用 ATL 方式编写“双接口”的组件。这一回将讨论IDispatch 接口和双接口......
使用者要想调用普通的 COM 组件功能，必须要加载这个组件的类型库(Type library)文件 tlb(比如在 VC 中使用 #import)。-introduces two ways to write automation (IDispatch) interface components procedures with MFC First approach to the preparation of "pure" IDispatch interface; Two methods are used to prepare ATL "dual interface" components.IDispatch ......

Description: 特徵:
1.在客戶端使用IDispatch使appserver可以作为接口使用.可以有代碼輸入提示啦,哈哈
2.支援服務器廣播,由服務器觸發客戶端事件.(callback).
實現過程:
1.在服务器的TLB里面定义一个ICLIENT,在客户端应用程序实现ICLIENT的接口.
2.APPSERVER定义一个注册ICLIENT到服务器的方法,在服务器的需要的时候调用ICLIENT.即可以反映到客戶端
-Feature : 1. The client uses to make appserver IDispatch interface can be used. Code can be input prompts -- catheterization, 2. Broadcasting server support, client server trigger events. (Callback). Implementation process : 1. The server inside the TLB definition a ICLIENT the client application program interface ICLIENT. 2.APPSERVER definition of a registered ICLIENT server, the server needs of the call ICLIENT. that is reflected to the client

Description: IE工具栏扩展 就是如何使IE扩展组件可以响应事件。 在自己的程序中使用过WebBrowser控件的朋友都知道，WebBrowser控件定义了诸如BeforeNavigate、DownloadComplete 等事件，我们可以通过编写事件处理代码实现对WebBrowser控件的操作。那么如何实现对IE的事件响应和处理呢？同建立IE面板一样。我们需要建立一个实现IObjectWithSite接口的COM组件，不同的是，我们还需要实现IDispatch接口，在IObjectWithSite接口的SetSite方法中获得IE的WebBrowser接口并建立自身与WebBrowser的连接，然后如果在IE的Webbrowser对象中发生什么事件的话，那么IE就会回调连接的IDispatch接口的Invoke方法。我们通过在Invoke方法中编写代码就可以获得IE事件了。这个利用的是COM编程的回调接口原理。-IE toolbar expansion is how to make IE components can be extended to respond incident. In their own procedures used WebBrowser Control friends all know, WebBrowser control such as the definition BeforeNavigate, DownloadComplete incidents, we can handle the matter through the preparation of code to achieve WebBrowser control operation. So how to achieve the right IE incident response and handling? IE with the establishment of the same panel. We need to build an interface to achieve IObjectWithSite COM different is, we also need to implement the IDispatch interface, the interface SetSite IObjectWithSite method was IE WebBrowser interface and establish their own connections with the WebBrowser, then if the IE object pda.en.wapedia.org what happens incident, then IE the pullback would IDispatc

Description: WebBrowser的8个方法和13个属性，以及它们的功能：
方法 说明
GoBack 相当于IE的“后退”按钮，使你在当前历史列表中后退一项
GoForward 相当于IE的“前进”按钮，使你在当前历史列表中前进一项
GoHome 相当于IE的“主页”按钮，连接用户默认的主页
GoSearch 相当于IE的“搜索”按钮，连接用户默认的搜索页面
Navigate 连接到指定的URL
Refresh 刷新当前页面
Refresh2 同上，只是可以指定刷新级别，所指定的刷新级别的值来自RefreshConstants枚举表，
该表定义在ExDisp.h中，可以指定的不同值如下：
REFRESH_NORMAL 执行简单的刷新，不将HTTP pragma: no-cache头发送给服务器
REFRESH_IFEXPIRED 只有在网页过期后才进行简单的刷新
REFRESH_CONTINUE 仅作内部使用。在MSDN里写着DO NOT USE! 请勿使用
REFRESH_COMPLETELY 将包含pragma: no-cache头的请求发送到服务器
Stop 相当于IE的“停止”按钮，停止当前页面及其内容的载入
属性 说明
Application 如果该对象有效，则返回掌管WebBrowser控件的应用程序实现的自动化对象(IDispatch)。如果在宿主对象中自动化对象无效，这个程序将返回WebBrowser
控件的自动化对象
Parent 返回WebBrowser控件的父自动化对象，通常是一个容器，例如是宿主或IE窗口
Container 返回WebBrowser控件容器的自动化对象。通常该值与Parent属性返回的值相同
Document 为活动的文档返回自动化对象。如果HTML当前正被显示在WebBrowser中，则
Document属性提供对DHTML Object Model的访问途径
TopLevelContainer 返回一个Boolean值，表明IE是否是WebBrowser控件顶层容器，是就返回true
Type 返回已被WebBrowser控件加载的对象的类型。例如：如果加载.doc文件，就会返
回Microsoft Word Document
Left 返回或设置WebBrowser控件窗口的内部左边与容器窗口左边的距离
Top 返回或设置WebBrowser控件窗口的内部左边与容器窗口顶边的距离
Width 返回或设置WebBrowser窗口的宽度，以像素为单位
Height 返回或设置WebBrowser窗口的高度，以像素为单位
LocationName 返回一个字符串，该字符串包含着WebBrowser当前显示的资源的名称，如果资源
是网页就是网页的标题；如果是文件或文件夹，就是文件或文件夹的名称
LocationURL 返回WebBrowser当前正在显示的资源的URL
Busy 返回一个Boolean值，说明WebBrowser当前是否正在加载URL，如果返回true
就可以使用stop方法来撤销正在执行的访问操作
如何利用 WebBrowser 控件,显示 .GIF 动画?
要有一定的网页知识(HTML、JavaScript、CSS)
注意细节:
没有"滚动条"和"鼠标右键弹出的 IE 上下文菜单",".HTM 源文件" ...
我写了一个,效果还真不错!
