Examples

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);  
}  

Remarks

TryToShow adjusts the location of the buffer in the code view so that the indicated range of text is displayed in the code editor, if possible. TryToShow is similar to the TextPane object's Activate method except that it attempts to display the window and the specified range of text.
