我为VS2010创建了一个插件，它使用一个单独的类来进行一些处理。结果是在“输出窗口”的新窗格中显示的文本。
此处理类的构造函数引用由addins Connect类创建的新OutputWindowPane。使用OutputString方法编写文本。
这样可以正确显示文本，但是，当执行返回到addins Connect类时，它会全部显示在一个更新中。我还注意到IDE似乎在addin运行时冻结。我是adin开发的新手，所以我错过了一些明显的东西吗？
有没有办法可以修改此过程，以便在每次调用OutputString时在输出窗口中更新文本？我希望有某种更新方法，但我一直无法找到它。
我注意到这与使用单独的类无关。以下示例说明了我的问题：
using System;
using Extensibility;
using EnvDTE;
using EnvDTE80;
using Microsoft.VisualStudio.CommandBars;
namespace MyAddin4
{
public class Connect : IDTExtensibility2, IDTCommandTarget
{
public void OnConnection(object application, ext_ConnectMode connectMode, object addInInst, ref Array custom)
{
_applicationObject = (DTE2)application;
_addInInstance = (AddIn)addInInst;
if(connectMode == ext_ConnectMode.ext_cm_UISetup)
{
object []contextGUIDS = new object[] { };
Commands2 commands = (Commands2)_applicationObject.Commands;
string toolsMenuName = "Tools";
CommandBar menuBarCommandBar = ((CommandBars)_applicationObject.CommandBars)["MenuBar"];
CommandBarControl toolsControl = menuBarCommandBar.Controls[toolsMenuName];
CommandBarPopup toolsPopup = (CommandBarPopup)toolsControl;
try
{
Command command = commands.AddNamedCommand2(_addInInstance, "MyAddin4", "MyAddin4", "Executes the command for MyAddin4", true, 59, ref contextGUIDS, (int)vsCommandStatus.vsCommandStatusSupported+(int)vsCommandStatus.vsCommandStatusEnabled, (int)vsCommandStyle.vsCommandStylePictAndText, vsCommandControlType.vsCommandControlTypeButton);
if((command != null) && (toolsPopup != null))
{
command.AddControl(toolsPopup.CommandBar, 1);
}
}
catch(ArgumentException) {}
}
}
public void OnDisconnection(ext_DisconnectMode disconnectMode, ref Array custom) {}
public void OnAddInsUpdate(ref Array custom) {}
public void OnStartupComplete(ref Array custom) {}
public void OnBeginShutdown(ref Array custom) {}
public void QueryStatus(string commandName, vsCommandStatusTextWanted neededText, ref vsCommandStatus status, ref object commandText)
{
if(neededText == vsCommandStatusTextWanted.vsCommandStatusTextWantedNone)
{
if(commandName == "MyAddin4.Connect.MyAddin4")
{
status = (vsCommandStatus)vsCommandStatus.vsCommandStatusSupported|vsCommandStatus.vsCommandStatusEnabled;
return;
}
}
}
public void Exec(string commandName, vsCommandExecOption executeOption, ref object varIn, ref object varOut, ref bool handled)
{
handled = false;
if(executeOption == vsCommandExecOption.vsCommandExecOptionDoDefault)
{
if(commandName == "MyAddin4.Connect.MyAddin4")
{
OutputWindow outputWindow = (OutputWindow) _applicationObject.Windows.Item(Constants.vsWindowKindOutput).Object;
OutputWindowPane outputPane = outputWindow.OutputWindowPanes.Add("Processor");
for (int i = 0; i < 10; i++)
{
System.Threading.Thread.Sleep(500);
outputPane.Activate();
outputPane.OutputString(i + "\n");
}
handled = true;
return;
}
}
}

private AddIn _addInInstance;
}
}
基于@ShellShock的答案，这是适用于我的解决方案：
using System;
using Extensibility;
using EnvDTE;
using EnvDTE80;
using Microsoft.VisualStudio.CommandBars;
namespace MyAddin4
{
public class Connect : IDTExtensibility2, IDTCommandTarget
{
public void OnConnection(object application, ext_ConnectMode connectMode, object addInInst, ref Array custom)
{
_applicationObject = (DTE2)application;
_addInInstance = (AddIn)addInInst;
if(connectMode == ext_ConnectMode.ext_cm_UISetup)
{
object []contextGUIDS = new object[] { };
Commands2 commands = (Commands2)_applicationObject.Commands;
string toolsMenuName = "Tools";
CommandBar menuBarCommandBar = ((CommandBars)_applicationObject.CommandBars)["MenuBar"];
CommandBarControl toolsControl = menuBarCommandBar.Controls[toolsMenuName];
CommandBarPopup toolsPopup = (CommandBarPopup)toolsControl;
try
{
Command command = commands.AddNamedCommand2(_addInInstance, "MyAddin4", "MyAddin4", "Executes the command for MyAddin4", true, 59, ref contextGUIDS, (int)vsCommandStatus.vsCommandStatusSupported+(int)vsCommandStatus.vsCommandStatusEnabled, (int)vsCommandStyle.vsCommandStylePictAndText, vsCommandControlType.vsCommandControlTypeButton);
if((command != null) && (toolsPopup != null))
{
command.AddControl(toolsPopup.CommandBar, 1);
}
}
catch(ArgumentException) {}
}
}
public void OnDisconnection(ext_DisconnectMode disconnectMode, ref Array custom) {}
public void OnAddInsUpdate(ref Array custom) {}
public void OnStartupComplete(ref Array custom) {}
public void OnBeginShutdown(ref Array custom) {}
public void QueryStatus(string commandName, vsCommandStatusTextWanted neededText, ref vsCommandStatus status, ref object commandText)
{
if(neededText == vsCommandStatusTextWanted.vsCommandStatusTextWantedNone)
{
if(commandName == "MyAddin4.Connect.MyAddin4")
{
status = (vsCommandStatus)vsCommandStatus.vsCommandStatusSupported|vsCommandStatus.vsCommandStatusEnabled;
return;
}
}
}
public void Exec(string commandName, vsCommandExecOption executeOption, ref object varIn, ref object varOut, ref bool handled)
{
handled = false;
if(executeOption == vsCommandExecOption.vsCommandExecOptionDoDefault)
{
if(commandName == "MyAddin4.Connect.MyAddin4")
{
OutputWindow outputWindow = (OutputWindow) _applicationObject.Windows.Item(Constants.vsWindowKindOutput).Object;
OutputWindowPane outputPane = outputWindow.OutputWindowPanes.Add("Processor");
Worker workerObject = new Worker(ref outputPane);
uint loops = 10;
System.Threading.Thread thread = new System.Threading.Thread(delegate() { workerObject.DoWork(loops); });
thread.Start();
handled = true;
return;
}
}
}
private DTE2 _applicationObject;
private AddIn _addInInstance;
}
public class Worker
{
private EnvDTE.OutputWindowPane _pcLintOutputWindowPane;
public Worker(ref EnvDTE.OutputWindowPane pcLintOutputWindowPane)
{
_pcLintOutputWindowPane = pcLintOutputWindowPane;
}
public void DoWork(uint loops)
{
for (int i = 0; i < loops; i++)
{
System.Threading.Thread.Sleep(500);
WriteText(i + "\n");
}
}
private void WriteText(string stringToWrite)
{
_pcLintOutputWindowPane.Activate();
_pcLintOutputWindowPane.OutputString(stringToWrite);
}
}
}
答案 0 :(得分：1)
这是我用来写入我的插件中的OutputWindowPane的内容，它会更新每个调用的文本。我正在使用VS2008，我不知道它在VS2010中的工作方式是否有所不同。
public class OutputPane
{
public string Name { get; private set; }
private OutputWindowPane _outputWindowPane;
private static object _outputWindowPaneLock = new object();
public OutputPane(string name)
{
Name = name;
}
public void Write(string text)
{
CreateOutputPane(Name); // Creates the OutputWindowPane if it does not already exist.
if (_outputWindowPane != null)
{
try
{
_outputWindowPane.Activate();
_outputWindowPane.OutputString(text);
}
catch (Exception ex1)
{
System.Diagnostics.Debug.WriteLine("Exception writing text '" + text + "': " + ex1.ToString());
// Exceeded maximum output pane size?
try
{
_outputWindowPane.Clear();
_outputWindowPane.OutputString(text);
}
catch (Exception ex2)
{
System.Diagnostics.Debug.WriteLine("Exception writing text '" + text + "': " + ex2.ToString());
}
}
}
}
编辑：我认为你还需要在后台线程上调用OutputWindowPane.OutputString，这是我在调用OutputPane.Write方法时所做的。所以使用你的代码，它将是这样的：
public void Exec(string commandName, vsCommandExecOption executeOption, ref object varIn, ref object varOut, ref bool handled)
{
handled = false;
if (executeOption == vsCommandExecOption.vsCommandExecOptionDoDefault)
{
if (commandName == "MyAddin4.Connect.MyAddin4")
{
OutputWindow outputWindow = (OutputWindow)_applicationObject.Windows.Item(Constants.vsWindowKindOutput).Object;
OutputWindowPane outputPane = outputWindow.OutputWindowPanes.Add("Processor");
System.Threading.Thread thread = new System.Threading.Thread(new System.Threading.ParameterizedThreadStart(OutputStringThread));
thread.Start(outputPane);
handled = true;
return;
}
}
}
private void OutputStringThread(object obj)
{
try
{
OutputWindowPane outputPane = (OutputWindowPane)obj;
for (int i = 0; i < 10; i++)
{
System.Threading.Thread.Sleep(500);
outputPane.Activate();
outputPane.OutputString(i + "\n");
}
}
catch (Exception ex)
{
// Handle exception
}
}
