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。其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插件 Connect 类创建的新 OutputWindowPane。文本是使用 OutputString 方法编写的。
这有效并且文本显示正确,但是,当执行返回到插件连接类时,它全部显示在一次更新中。我还注意到,在插件运行时 IDE 似乎冻结了。我是插件开发的新手,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在每次调用 OutputString 时更新输出窗口中的文本?我希望有某种更新方法,但我一直找不到。
更新
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 DTE2 _applicationObject;
private AddIn _addInInstance;
}
}
解决方案
基于@ShellShock 的答案,这是适合我的解决方案:
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) {}
}
