如何从activewindow获取SOleUndoManager [英] How to get SOleUndoManager from activewindow

问题描述

我正在尝试在活动窗口(.cs文件)上获得SOleUndoManager的有效实例，我尝试了不同的方法，但尚未找到如何获取它的方法. 我正在使用VSPackage，并且具有对EnvDTE的引用，对于活动窗口也具有IVsWindowFrame的引用 拜托，您能告诉我向SOleUndoManager获取有效实例的正确方法是什么? 预先非常感谢您， (如果需要更多信息，我可以提供)

Hi, I'm trying to get a valid instance for SOleUndoManager on active window, (.cs file), I have tried different ways but not found yet how to get it I'm working on a VSPackage and have a reference to EnvDTE, also to IVsWindowFrame for active window Please, can you tell me what is the right way to get a valid instance to SOleUndoManager? Thank you very much in advance, (if you need further information I can provide)

推荐答案

耶稣，

您应该通过调用以下方法为给定的IVsWindowFrame检索IServiceProvider.具有VSFPROPID_SPFrame的IVsWindowFrame.GetProperty.然后，您可以构造一个新的ServiceProvider对象，从中应该可以从该对象调用GetService for SOleUndoManager.

例如，我使用了类似的方法在属性浏览器工具窗口上检索ITrackSelection接口:

Hi Jesus,

You should retrieve the IServiceProvider for the given IVsWindowFrame, by calling IVsWindowFrame.GetProperty with VSFPROPID_SPFrame. You can then construct a new ServiceProvider object, from which you should be able to call GetService for SOleUndoManager.

For example, I used something similar to retrieve the ITrackSelection interface on the property browser toolwindow:

 

IVsUIShell vsShell =( )serviceProvider.GetService( typeof )))；
Guid guidPropBrowser = 新 向导 ( .PropertyBrowser);
vsShell.FindToolWindow(( 很细 ) .FTW_fForceCreate， ref 输出 frameProperties);
objFrameSP;
frameProperties.GetProperty(( int ) __ VSFPROPID .VSFPROPID_SPFrame， 输出 objFrameSP);
frameSP = 新 (( IOleServiceProvider )objFrameSP);
ITrackSelection trackSelection = frameSP.GetService( typeof ( STrackSelection ITrackSelection ; IOleServiceProvider定义为:

使用 IOleServiceProvider = Microsoft.VisualStudio.OLE.Interop. IServiceProvider ;

   IVsUIShell vsShell = (IVsUIShell)serviceProvider.GetService(typeof(SVsUIShell));
   Guid guidPropBrowser = new Guid(ToolWindowGuids.PropertyBrowser);
   vsShell.FindToolWindow((uint)__VSFINDTOOLWIN.FTW_fForceCreate, ref guidPropBrowser, out frameProperties);

   object objFrameSP;
   frameProperties.GetProperty((int)__VSFPROPID.VSFPROPID_SPFrame, out objFrameSP);
   ServiceProvider frameSP = new ServiceProvider((IOleServiceProvider)objFrameSP);
   ITrackSelection trackSelection = frameSP.GetService(typeof(STrackSelection)) as ITrackSelection;where IOleServiceProvider is defined with:

   using IOleServiceProvider = Microsoft.VisualStudio.OLE.Interop.IServiceProvider;
