Tablet.IsPacketPropertySupported 方法
返回一个值，表示此 Tablet 对象是否支持标有全局唯一标识符 (GUID) 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 ( _
id As Guid _
) As Boolean
用法
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
参数
- id
类型：System.Guid
您正在检查的 PacketProperty 的 Guid 标识符。
返回值
类型：System.Boolean
返回一个值，表示此 Tablet 对象是否支持标有全局唯一标识符 (GUID) 的 PacketProperty 字段。
值 |
含义 |
|---|---|
true |
此 Tablet 对象支持 PacketProperty 字段。 |
false |
此 Tablet 对象不支持 PacketProperty 字段。 |
备注
此方法确定 Tablet 对象是否支持 PacketProperty 类的各个字段。
备注
如果在某些消息处理程序内调用此函数，则可以重新进入此函数，从而导致意外的结果。在处理以下任一消息时，请注意避免可重入调用：WM_ACTIVATE、WM_ACTIVATEAPP、WM_NCACTIVATE、WM_PAINT；WM_SYSCOMMAND（如果 wParam 设置为 SC_HOTKEY 或 SC_TASKLIST）；以及 WM_SYSKEYDOWN（处理 Alt-Tab 或 Alt-Esc 组合键时）。这是单线程单元模型应用程序的问题。
