Artikel
10/19/2012

Returns a value that indicates whether a PacketProperty field, identified with a globally unique identifier (GUID), is supported by this Tablet object.

Namespace: Microsoft.Ink
Assembly: Microsoft.Ink (in Microsoft.Ink.dll)

Syntax

'Declaration
Public Function IsPacketPropertySupported ( _
    id As Guid _
) As Boolean
'Usage
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 function IsPacketPropertySupported(
    id : Guid
) : boolean

Parameters

id
Type: System.Guid

The Guid identifier for the PacketProperty that you are checking.

Return Value

Type: System.Boolean
Returns a value that indicates whether a PacketProperty field, identified with a globally unique identifier (GUID), is supported by this Tablet object.

Value	Meaning
true	The PacketProperty field is supported by this Tablet object.
false	The PacketProperty field is not supported by this Tablet object.

Remarks

This method determines if a Tablet object supports various fields of the PacketProperty class.

Note

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.

Examples

This example reports which PacketProperty fields are available for the default Tablet object of the Tablets collection.
