語法

'宣告
Function TryToShow ( _
    How As vsPaneShowHow, _
    PointOrCount As Object _
) As Boolean

bool TryToShow(

    Object PointOrCount

參數

How
型別：EnvDTE.vsPaneShowHow
選擇項。vsPaneShowHow 常數，決定如何顯示程式碼。

PointOrCount
型別：System.Object
選擇項。要顯示之文字選取範圍的結束點。可能為 TextPoint 或整數。

傳回值

型別：System.Boolean
如果文字寬度符合目前的程式碼編輯器，則為 true，否則為 false。

實作

TextPoint.TryToShow(vsPaneShowHow, Object)

備註

TryToShow 會調整程式碼檢視下的緩衝區位置，以致指定範圍的文字能在程式碼編輯器中顯示。 TryToShow 與 TextPane 物件的 Activate 方法類似，不同之處在於前者是嘗試顯示視窗以及指定的文字範圍。

範例

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);
}
