如何：控制“输出”窗口

项目
08/12/2011

**“输出”窗口在集成开发环境 (IDE) 中显示各种功能的状态消息。这些消息包括在编译项目时发生的生成错误，以及对照目标数据库检查存储过程中的 Transact-SQL 语法时的结果。某些 IDE 功能（如外部工具功能或“命令”窗口中调用的命令）将输出传递到特殊的“输出”窗口窗格。来自外部工具（如 .bat 或 .com 文件）的输出通常在 Windows 命令提示符窗口中显示，但也可以在“输出”**窗口中显示。

Visual Studio 自动化模型提供以下可用于控制**“输出”**窗口的对象。

对象名	说明
OutputWindow	表示“输出”窗口。
OutputWindowPanes	一个包含“输出”窗口中的所有窗格的集合。
OutputWindowPane	表示“输出”窗口中的一个窗格。
OutputWindowEvents	使您可以响应“输出”窗口中发生的事件。

除了控制**“输出”**窗口的内容之外，还可以控制窗口的宽度和高度等特性。有关更多信息，请参见如何：更改窗口特性。

通过使用 TextDocument 对象、EditPoint 对象和类似的对象，可以用 Visual Studio 编辑器自动化模型操作**“输出”**窗口窗格中的文本，就如同可以在代码编辑器中操作代码一样。有关更多信息，请参见如何：控制代码编辑器 (Visual Basic)。

提示

显示的对话框和菜单命令可能会与“帮助”中的描述不同，具体取决于您现用的设置或版本。这些过程是在“常规开发设置”处于活动状态时开发的。若要更改设置，请在“工具”菜单上单击“导入和导出设置”。有关更多信息，请参见使用设置。

示例

此示例演示了如何将新的窗口窗格添加到**“输出”**窗口，以及如何向其添加文本。有关如何运行本示例的更多信息，请参见如何：编译和运行自动化对象模型代码示例。

Public Sub OnConnection(ByVal application As Object, ByVal _
  connectMode As ext_ConnectMode, ByVal addInInst As Object, _
  ByRef custom As Array) Implements IDTExtensibility2.OnConnection
    _applicationObject = CType(application, DTE2)
    _addInInstance = CType(addInInst, AddIn)
    ' Pass the applicationObject member variable to the code example.
    OutputWindowTest(_applicationObject)
End Sub

Sub OutputWindowTest(ByVal dte As DTE2)
    ' Create a tool window reference for the Output window
    ' and window pane.
    Dim ow As OutputWindow = dte.ToolWindows.OutputWindow
    Dim owP As OutputWindowPane

    ' Add a new pane to the Output window.
    owP = ow.OutputWindowPanes.Add("A New Pane")
    ' Add a line of text to the new pane.
    owP.OutputString("Some Text")
End Sub

public void OnConnection(object application, ext_ConnectMode 
  connectMode, object addInInst, ref Array custom)
{
    _applicationObject = (DTE2)application;
    _addInInstance = (AddIn)addInInst;
    // Pass the applicationObject member variable to the code example.
    OutputWindowTest(_applicationObject);
}

public void OutputWindowTest(DTE2 dte)
{
    // Create a tool window reference for the Output window
    // and window pane.
    OutputWindow ow = dte.ToolWindows.OutputWindow;
    OutputWindowPane owP;

    // Add a new pane to the Output window.
    owP = ow.OutputWindowPanes.Add("A New Pane");
    // Add a line of text to the new pane.
    owP.OutputString("Some Text");
}

此示例向**“输出”窗口的“生成”**窗格添加文本，然后检索此文本。

Public Sub OnConnection(ByVal application As Object, ByVal _
  connectMode As ext_ConnectMode, ByVal addInInst As Object, _
  ByRef custom As Array) Implements IDTExtensibility2.OnConnection
    _applicationObject = CType(application, DTE2)
    _addInInstance = CType(addInInst, AddIn)
    ' Pass the applicationObject member variable to the code example.
    writeReadOW(_applicationObject)
End Sub

Sub writeReadOW(ByVal dte As DTE2)
    ' Add-in code.
    ' Create a reference to the Output window.
    ' Create a tool window reference for the Output window
    ' and window pane.
    Dim ow As OutputWindow = dte.ToolWindows.OutputWindow
    Dim owP As OutputWindowPane
    ' Create a reference to the pane contents.
    Dim owPTxtDoc As TextDocument

    ' Select the Build pane in the Output window.
    owP = ow.OutputWindowPanes.Item("Build")
    owP.Activate()
    owPTxtDoc = owP.TextDocument

    ' Put some text in the pane.
    owP.OutputString("Testing 123.")
    ' Retrieve the text contents of the pane.
    MsgBox("Startpoint: " & owPTxtDoc.StartPoint.DisplayColumn)
    MsgBox(owPTxtDoc.StartPoint.CreateEditPoint. _
      GetText(owPTxtDoc.EndPoint))
End Sub

using System.Windows.Forms;
public void OnConnection(object application, ext_ConnectMode 
  connectMode, object addInInst, ref Array custom)
{
    _applicationObject = (DTE2)application;
    _addInInstance = (AddIn)addInInst;
    // Pass the applicationObject member variable to the code example.
    writeReadOW(_applicationObject);
}

public void writeReadOW(DTE2 dte)
{
    // Add-in code.
    // Create a reference to the Output window.
    // Create a tool window reference for the Output window
    // and window pane.
    OutputWindow ow = dte.ToolWindows.OutputWindow;
    OutputWindowPane owP;
    // Create a reference to the pane contents.
    TextDocument owPTxtDoc;
    EditPoint2 strtPt;

    // Select the Build pane in the Output window.
    owP = ow.OutputWindowPanes.Item("Build");
    owP.Activate();
    owPTxtDoc = owP.TextDocument;
            
    // Put some text in the pane.
    owP.OutputString("Testing 123.");
    // Retrieve the text contents of the pane.
    System.Windows.Forms.MessageBox.Show("Startpoint: " + 
      owPTxtDoc.StartPoint.DisplayColumn);
    strtPt = (EditPoint2)owPTxtDoc.StartPoint.CreateEditPoint();
    System.Windows.Forms.MessageBox.Show
      (strtPt.GetText(owPTxtDoc.EndPoint));
}
