Tablet.PlugAndPlayId 屬性

取得 Tablet 物件的隨插即用識別項的字串表示。

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

語法

'宣告
Public ReadOnly Property PlugAndPlayId As String
'用途
Dim instance As Tablet
Dim value As String

value = instance.PlugAndPlayId

public string PlugAndPlayId { get; }

public:
property String^ PlugAndPlayId {
    String^ get ();
}

/** @property */
public String get_PlugAndPlayId()

public function get PlugAndPlayId () : String

屬性值

型別：System.String
Tablet 物件的隨插即用識別項。

備註

傳回值取決於 HIDD_ATTRIBUTES.ProductID (英文) 項目。手寫板裝置的製造商負責加入這個字串。如果手寫板裝置沒有識別項，則傳回值是空的。

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。

範例

這個範例會報告隨插即用 ID、硬體功能，以及 Tablets 集合中預設 Tablet 物件的最大輸入矩形。
