This property is read-only.
For more information about the VARIANT and BSTR data types, see Using the Automation Library.
Return Value
| HRESULT value | Description |
|---|---|
| S_OK | Success. |
| E_POINTER | The parameter pointer was invalid. |
| E_INK_EXCEPTION | An exception occurred inside the method. |

Remarks
For a complete list of available packet properties, see the PacketProperty constants.
In Visual Basic 6.0, if you try to access the PacketDescription parameter's GUID array data by using the IDispatch interface, run-time error 451 occurs. This error occurs because Visual Basic treats the "(0)" in "theStrokes.PacketDescription(0)" as a parameter being passed to the PacketDescription property rather than as an index into the array contained in the PacketDescription parameter. To avoid this error, you can assign the array to a temporary variable dimensioned as a BSTR array and then index the variable or you can declare the containing object directly with a Dim x As Type statement instead of through the IDispatch interface using a CreateObject() call.
Example
[Visual Basic 6.0]
This Visual Basic 6.0 example returns the packet data GUID of an IInkStrokeDisp object, theStroke.
[Visual Basic]
Dim thePacketDescription(0) As Variant
thePacketDescription(0) = theStroke.PacketDescription(0)
