'Declaration
 
Protected Overridable Function NameHitTest( _
   ByVal testPoint As AnnPoint, _
   ByVal buffer As Integer _
) As Object

'Usage
 
Dim instance As AnnObject
Dim testPoint As AnnPoint
Dim buffer As Integer

   AnnPoint testPoint,
   int buffer
)

   testPoint ,
   buffer 
)

   AnnPoint testPoint,
   int buffer
) 

Parameters

testPoint

The AnnPoint to be tested.

buffer

Threshold buffer value, in pixels.

Return Value

This method is called internally by the annotation framework whenever the HitTest method is called. You do not need to call this property directly.

testPoint should be in physical coordinates.

buffer is used to make the test point "bigger" to compensate for errors and provide smoother hit-testing. For example, if buffer is 2, a square with a length of 4 pixels around testPoint will be used to perform the hit-testing.

If the name of this object is invisible (NameVisible is set to false), this method will not be called.

By default, an annotation object will return NameHitTestValue if hit-testing the name was satisfied

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
