Parameters

  • PointOrCount
    Type: System.Object

    Optional. A variant representing the end of a range of text to show. If PointOrCount is a number of characters, the characters follow Point. If PointOrCount is a point before Point, then it will be at the top of the text pane if How is set to vsPaneShowTop.

    If How is set to vsPaneShowCentered, and the number of lines in the selected text is greater than the height of the pane, then the top line of the selected text is placed at the top of the pane.

Return Value

Type: System.Boolean
true if the text can be displayed; otherwise, false.

    and " & Str(objPane.Width) & " columns wide.")
    objStart = objPane.StartPoint
    MsgBox("It begins at line " & Str(objStart.Line) & ", column " & _
    Str(objStart.LineCharOffset) & ".")
    objPane.TryToShow(objStart, vsPaneShowHow.vsPaneShowCentered)
