Syntaxe

'Déclaration
Public Function IsPacketPropertySupported ( _
    id As Guid _
) As Boolean
'Utilisation
Dim instance As Tablet
Dim id As Guid
Dim returnValue As Boolean

returnValue = instance.IsPacketPropertySupported(id)
public bool IsPacketPropertySupported(
    Guid id
)
public:
bool IsPacketPropertySupported(
    Guid id
)
public boolean IsPacketPropertySupported(
    Guid id
)
public function IsPacketPropertySupported(
    id : Guid
) : boolean

Paramètres

Valeur de retour

Type : System.Boolean
Retourne une valeur qui indique si un champ PacketProperty, ayant un identificateur global unique (GUID), est pris en charge par cet objet Tablet.

Valeur

Signification

true

Le champ PacketProperty est pris en charge par cet objet Tablet.

false

Le champ PacketProperty n'est pas pris en charge par cet objet Tablet.

Notes

Cette méthode détermine si un objet Tablet prend en charge différents champs de la classe PacketProperty.

ms570104.alert_note(fr-fr,VS.90).gifRemarque :

Cette fonction peut être exécutée à nouveau si elle est appelée dans certains gestionnaires de messages et provoquer des résultats inattendus. Prenez soin d'éviter un appel réentrant lors de la gestion de l'un des messages suivants : WM_ACTIVATE, WM_ACTIVATEAPP, WM_NCACTIVATE, WM_PAINT; WM_SYSCOMMAND si wParam a la valeur SC_HOTKEY ou SC_TASKLIST, et WM_SYSKEYDOWN (lors de l'utilisation des raccourcis clavier Alt+Tab ou Alt+Echap). Cette opération pose problème dans les applications de modèle de thread unique cloisonné.
