    Top As Long, _
    Left As Long, _
    Bottom As Long, _
    Right As Long _
)
      

Parameters

Top

[in] The top of the rectangle.

Left

Bottom

[in] The bottom of the rectangle.

Right

[in] The right of the rectangle.

Return Value

HRESULT value Description
S_OK Success.
E_POINTER A parameter contained an invalid pointer.
E_INK_EXCEPTION An exception occurred inside the method.

Example

[Visual Basic 6.0]

This Visual Basic 6.0 example draws a rectangle on the form with a red outline when the packets in the NewPackets event are within the rectangle or with a black outline when the packets are outside the rectangle. This demonstrates how to use the packet events to control application behaviors.
