定义

命名空间:
EnvDTE80
程序集:
EnvDTE80.dll
程序集:

尝试显示文本点的位置。

bool TryToShow(EnvDTE::vsPaneShowHow How = EnvDTE.vsPaneShowHow.vsPaneShowCentered, winrt::Windows::Foundation::IInspectable const & PointOrCount);
[System.Runtime.InteropServices.DispId(50)]
public bool TryToShow (EnvDTE.vsPaneShowHow How = EnvDTE.vsPaneShowHow.vsPaneShowCentered, object PointOrCount);
[<System.Runtime.InteropServices.DispId(50)>]
abstract member TryToShow : EnvDTE.vsPaneShowHow * obj -> bool
Public Function TryToShow (Optional How As vsPaneShowHow = EnvDTE.vsPaneShowHow.vsPaneShowCentered, Optional PointOrCount As Object) As Boolean

参数

How
vsPaneShowHow

可选。 一个 vsPaneShowHow 常数，该常数确定代码的显示方式。

PointOrCount
Object

可选。 要显示的文本选定范围的终结点。 可以是 TextPoint 或整数。

返回

Boolean

如果文本的跨距在当前代码编辑器内，则为 true；否则为 false。

实现

TryToShow(vsPaneShowHow, Object)
属性
DispIdAttribute

示例

Sub TryToShowExample(ByVal dte As DTE2)  

    ' Before running this example, open a text document.  
    Dim win As Window = dte.ActiveWindow  
    Dim textWin As TextWindow = CType(win.Object, TextWindow)  

    ' Split the text document window.  
    Dim cmd As Command = dte.Commands.Item("Window.Split")  
    dte.Commands.Raise(cmd.Guid, cmd.ID, Nothing, Nothing)  

    ' Display the beginning of the document in the top pane and the   
    ' end of the document in the bottom pane.  
    Dim sel As TextSelection = textWin.Panes.Item(2).Selection  
    sel.StartOfDocument()  
    sel.ActivePoint.TryToShow()  
    sel = textWin.Panes.Item(1).Selection  
    sel.EndOfDocument()  
    sel.ActivePoint.TryToShow()  

End Sub  

public void TryToShowExample(DTE2 dte)  
{  
    // Before running this example, open a text document.  
    Window win = dte.ActiveWindow;  
    TextWindow textWin = (TextWindow)win.Object;  

    // Split the text document window.  
    Command cmd = dte.Commands.Item("Window.Split", -1);  
    object dummy = null;  
    dte.Commands.Raise(cmd.Guid, cmd.ID, ref dummy, ref dummy);  

    // Display the beginning of the document in the top pane and the   
    // end of the document in the bottom pane.  
    TextSelection sel = textWin.Panes.Item(2).Selection;  
    sel.StartOfDocument(false);  
    sel.ActivePoint.TryToShow(vsPaneShowHow.vsPaneShowCentered, null);  
    sel = textWin.Panes.Item(1).Selection;  
    sel.EndOfDocument(false);  
    sel.ActivePoint.TryToShow(vsPaneShowHow.vsPaneShowCentered, null);  
}

注解

TryToShow 在代码视图中调整缓冲区的位置，以便在代码编辑器中显示指定范围内的文本（如果可能）。 TryToShow 与 TextPane 对象的方法类似， Activate 不同之处在于，它尝试显示窗口和指定范围的文本。
