Значение свойства

Тип: System.String
The Plug and Play identifier of the Tablet object.

Заметки

The return value is based upon the HIDD_ATTRIBUTES.ProductID element. The manufacturer of the tablet device is responsible for adding this string. The return value is empty if the tablet device does not have an identifier.

Примечание.
This function can be re-entered if called within certain message handlers, causing unexpected results. Take care to avoid a reentrant call when handling any of the following messages: WM_ACTIVATE, WM_ACTIVATEAPP, WM_NCACTIVATE, WM_PAINT; WM_SYSCOMMAND if wParam is set to SC_HOTKEY or SC_TASKLIST; and WM_SYSKEYDOWN (when processing Alt-Tab or Alt-Esc key combinations). This is an issue with single-threaded apartment model applications.

This example reports on the Plug and Play ID, the hardware capabilities and the maximum input rectangle of the default Tablet object in the Tablets collection.

    Dim defTablet As Tablet = New Tablets().DefaultTablet

    SB.AppendLine("PlugAndPlayId: " + defTablet.PlugAndPlayId)

    If (defTablet.HardwareCapabilities And TabletHardwareCapabilities.CursorMustTouch) <> 0 Then
        SB.AppendLine("CursorMustTouch: YES")
    Else
        SB.AppendLine("CursorMustTouch: NO")
    End If

        SB.AppendLine("Integrated: YES")
    Else
        SB.AppendLine("Integrated: NO")
    End If

    SB.AppendLine("MaximumInputRectangle " + defTablet.MaximumInputRectangle.ToString())

    Return SB.ToString()
