Actualización: noviembre 2007

Devuelve los datos de las métricas de un objeto PacketProperty conocido.

Espacio de nombres: Microsoft.Ink
Ensamblado: Microsoft.Ink (en Microsoft.Ink.dll)

Sintaxis

'Declaración
Public Function GetPropertyMetrics ( _
    id As Guid _
) As TabletPropertyMetrics
'Uso
Dim instance As Tablet
Dim id As Guid
Dim returnValue As TabletPropertyMetrics

returnValue = instance.GetPropertyMetrics(id)

public TabletPropertyMetrics GetPropertyMetrics(
    Guid id
)

public:
TabletPropertyMetrics GetPropertyMetrics(
    Guid id
)

public TabletPropertyMetrics GetPropertyMetrics(
    Guid id
)

public function GetPropertyMetrics(
    id : Guid
) : TabletPropertyMetrics

Parámetros

id
Tipo: System.Guid
El identificador Guid del objeto PacketProperty que está solicitando.

Valor devuelto

Tipo: Microsoft.Ink.TabletPropertyMetrics
Este método devuelve un objeto TabletPropertyMetrics de la propiedad solicitada que admite el Tablet PC.

Comentarios

Las propiedades para las que se recogen métricas pueden incluir la hora en que se generó un paquete o la presión de la punta de la pluma sobre la superficie del Tablet PC.

Nota

Esta función puede introducirse de nuevo si se llama en determinados controladores de mensajes, lo cual causa resultados inesperados. Procure evitar que se produzca una llamada reentrante al controlar alguno de los siguientes mensajes WM_ACTIVATE, WM_ACTIVATEAPP, WM_NCACTIVATE, WM_PAINT; WM_SYSCOMMAND si wParam se establece en SC_HOTKEY o SC_TASKLIST y WM_SYSKEYDOWN (al procesar las combinaciones de teclas Alt-Tab o Alt-Esc). Este problema se produce con las aplicaciones del modelo de subprocesamiento controlado simple.

Ejemplos

En este ejemplo se informa sobre las métricas de cada propiedad admitida del objeto Tablet predeterminado de la colección Tablets.
