發行項
10/29/2008

傳回值，這個值表示此 Tablet 物件是否支援使用全域唯一識別項 (GUID) 識別的 PacketProperty 欄位。

命名空間： Microsoft.Ink
組件： Microsoft.Ink (在 Microsoft.Ink.dll 中)

語法

'宣告
Public Function IsPacketPropertySupported ( _
    id As Guid _
) As Boolean
'用途
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

參數

id
型別：System.Guid
所檢查之 PacketProperty 的 Guid (英文) 識別項。

傳回值

型別：System.Boolean
傳回值，這個值表示此 Tablet 物件是否支援使用全域唯一識別項 (GUID) 識別的 PacketProperty 欄位。

值	意義
true	此 Tablet 物件支援 PacketProperty 欄位。
false	此 Tablet 物件不支援 PacketProperty 欄位。

備註

這個方法會判斷 Tablet 物件是否支援 PacketProperty 類別的各種欄位。

注意事項：
如果在特定訊息處理常式內呼叫的話，可能會重新輸入這個函式，造成非預期的結果。處理下列訊息時，請小心避免使用可重新進入的呼叫：WM_ACTIVATE、WM_ACTIVATEAPP、WM_NCACTIVATE、WM_PAINT、WM_SYSCOMMAND (如果 wParam 設定為 SC_HOTKEY 或 SC_TASKLIST) 和 WM_SYSKEYDOWN (處理 ALT+TAB 或 ALT+ESC 組合鍵時)。不過在單一執行緒 Apartment Model (STA) 應用程式中會發生問題。
