DTE2事件不火 [英] DTE2 events don't fire

问题描述

在试图开发我的第一个VS插件，我有在射击DTE2事件的问题。

基本上，DocumentOpened和LineChanged事件不火出于某种原因。什么重要组成部分，我错过了。

 命名空间TestAddin {
公共类连接：IDTExtensibility2的{
私人的AddIn _addInInstance; 
私人DTE2 _applicationObject; 
 
公共无效的OnConnection（对象应用程序，ext_ConnectMode connectMode，对象addInInst，楼盘阵列定制）{
 _applicationObject =（DTE 2）申请; 
 _addInInstance =（外接程序）addInInst; 
 
 _applicationObject.Events.DocumentEvents.DocumentOpened + = InitializeFoldingOnDocument; 
 _applicationObject.Events.TextEditorEvents.LineChanged + = UpdateFoldingOnDocument; 
} 
 
私人无效UpdateFoldingOnDocument（TextPoint起点，终点TextPoint，诠释提示）{
 RegionFolding（_applicationObject.ActiveDocument）; 
} 
 
私人无效InitializeFoldingOnDocument（文档文件）{
 RegionFolding（文件）; 
} 
 
私人无效RegionFolding（文档_document）{
 //执行折叠[...] 
} 
 
 //其他成员IDTExtensibility2的[...] 
} 
} 
  

解决方案

您需要保存DocumentEvents类。
我想他们会desposed或垃圾收集东西。

在我的情况。

 私人solutionEvents solutionEvents; 
 
公共无效的OnConnection（对象应用程序，ext_ConnectMode connectMode，对象addInInst，楼盘阵列定制）
 {
 Globals.DTE =（DTE 2）申请; 
 Globals.Addin =（外接程序）addInInst; 
 
 solutionEvents = Globals.DTE.Events.SolutionEvents; 
 solutionEvents.Opened + =新_dispSolutionEvents_OpenedEventHandler（SolutionEvents_Opened）; 
 solutionEvents.BeforeClosing + =新_dispSolutionEvents_BeforeClosingEventHandler（SolutionEvents_BeforeClosing）; 
} 
  

While trying to develop my first VS Addin, I am having issues in firing DTE2 events.

Basically, the DocumentOpened and LineChanged events don't fire for some reason. What important part did I miss?

namespace TestAddin {
  public class Connect : IDTExtensibility2 {
    private AddIn _addInInstance;
    private DTE2 _applicationObject;

    public void OnConnection(object application, ext_ConnectMode connectMode, object addInInst, ref Array custom) {
      _applicationObject = (DTE2) application;
      _addInInstance = (AddIn) addInInst;

      _applicationObject.Events.DocumentEvents.DocumentOpened += InitializeFoldingOnDocument;
      _applicationObject.Events.TextEditorEvents.LineChanged += UpdateFoldingOnDocument;
    }

    private void UpdateFoldingOnDocument(TextPoint startpoint, TextPoint endpoint, int hint) {
      RegionFolding(_applicationObject.ActiveDocument);
    }

    private void InitializeFoldingOnDocument(Document document) {
      RegionFolding(document);
    }

    private void RegionFolding(Document _document) {
      // Do the folding [...]
    }

    // Other IDTExtensibility2 Members [...]
  }
}

解决方案

You need to save the DocumentEvents class. I think they will be desposed or garbage collected else.

In my case.

private SolutionEvents solutionEvents;

public void OnConnection(object application, ext_ConnectMode connectMode, object addInInst, ref Array custom)
{
    Globals.DTE = (DTE2)application;
    Globals.Addin = (AddIn)addInInst;

    solutionEvents = Globals.DTE.Events.SolutionEvents;
    solutionEvents.Opened += new _dispSolutionEvents_OpenedEventHandler(SolutionEvents_Opened);
    solutionEvents.BeforeClosing += new _dispSolutionEvents_BeforeClosingEventHandler(SolutionEvents_BeforeClosing);
}
