Tablets.IsPacketPropertySupported 方法

项目
10/28/2008

返回一个值，该值指示此 Tablets 集合中的所有 Tablet 对象是否都支持以全局唯一标识符 (GUID) 标识的 PacketProperty 字段。

命名空间： Microsoft.Ink
程序集： Microsoft.Ink（在 Microsoft.Ink.dll 中）

语法

声明
Public Function IsPacketPropertySupported ( _
    g As Guid _
) As Boolean
用法
Dim instance As Tablets
Dim g As Guid
Dim returnValue As Boolean

returnValue = instance.IsPacketPropertySupported(g)

public bool IsPacketPropertySupported(
    Guid g
)

public:
bool IsPacketPropertySupported(
    Guid g
)

public boolean IsPacketPropertySupported(
    Guid g
)

public function IsPacketPropertySupported(
    g : Guid
) : boolean

参数

g
类型：System.Guid
所请求的 PacketProperty 字段的 Guid 标识符。

返回值

类型：System.Boolean
返回一个值，该值指示此 Tablets 集合中的所有 Tablet 对象是否都支持以全局唯一标识符 (GUID) 标识的 PacketProperty 字段。

值	含义
true	此 Tablets 集合中的所有对象都支持 PacketProperty 字段。
false	不是此 Tablets 集合中的所有对象都支持 PacketProperty 字段。

备注

此方法确定 Tablets 集合是否支持 PacketProperty 类的各个字段。

备注

对 Tablets 集合调用此方法时，将查询系统上的所有 Tablet。如果其中任何一个 Tablet 不支持该属性，则返回 false。对单个 Tablet 对象调用 Tablet.IsPacketPropertySupported 方法以确定该设备是否支持某已知属性。

示例

此示例报告对于 Tablets 集合 allTablets 中的所有 Tablet 对象，有哪些 PacketProperty 字段可用。
