HTMLWindow3 接口
更新：2007 年 11 月
表示 Visual Studio 集成开发环境 (IDE) 中的 HTML 文档窗口。
命名空间： EnvDTE90
程序集： EnvDTE90（在 EnvDTE90.dll 中）

<GuidAttribute("BAD0A3DD-8109-4684-B806-A5282267BFE4")> _
Public Interface HTMLWindow3
用法
Dim instance As HTMLWindow3
[GuidAttribute("BAD0A3DD-8109-4684-B806-A5282267BFE4")]
public interface HTMLWindow3
[GuidAttribute(L"BAD0A3DD-8109-4684-B806-A5282267BFE4")]
public interface class HTMLWindow3
public interface HTMLWindow3
备注
当文档是 HTML 文档时，HTMLWindow3 由 Window 对象的 Object 属性返回。将 CurrentTab 属性设置为 vsHTMLTabsSource 时，Window.Selection 和 Document.Selection 返回一个 TextSelection 对象。
随着 Visual Studio 2008 HTML 编辑器中“拆分”视图的引入，增加了 HTMLWindow3、vsHTMLPanes 和 vsHTMLViews。“拆分”视图将 HTML 编辑器窗口的选项卡和视图元素分隔开来。切换视图（到“设计”或“源”视图）并不一定意味着切换选项卡（“设计”/“拆分”/“源”）。例如，当您单击“拆分”选项卡时，在“设计”和“源”之间切换视图不会更改选项卡，而只会在“拆分”视图中激活或取消激活“设计”和“源”部分。
Visual Studio 2008 HTMLWindow 对象现在还实现 HTMLWindow3 接口，该接口返回当前视图（“设计”或“源”）和当前窗格（“设计”、“源”或“拆分”选项卡）。
HTMLWindow3 规则
HTMLWindow3 的行为是：
获取
当前窗格（选项卡） |
当前视图返回 |
|---|---|
vsHTMLViewDesign 或 vsHTMLViewSource，具体取决于哪个部分处于活动状态。 |
设置
当前窗格（选项卡） |
