  [in]   BSTR IpTo,
  [out]  VARIANT_BOOL* pIsRangeIntersect
);

Parameters

  • IpFrom
    Required. BSTR that specifies the lower bound of the IP address range.

  • IpTo
    Required. BSTR that specifies the upper bound of the IP address range.

  • pIsRangeIntersect
    Pointer to a Boolean variable that is set on return to VARIANT_TRUE if the IP address range intersects any of the IP address ranges in the collection, or to VARIANT_FALSE if the IP address range does not intersect any of the IP address ranges in the collection.

Return Value

This method can return one of the following:

  • S_OK, indicating that the operation succeeded.
  • An error code, indicating that the operation failed.

Visual Basic

Syntax

Function IsRangeIntersect( _
  ByVal IpFrom As String, _
  ByVal IpTo As String _
) As Boolean

Parameters

  • IpFrom
    Required. String that specifies the lower bound of the IP address range.
  • IpTo
    Required. String that specifies the upper bound of the IP address range.

Return Value

This method returns a Boolean value that is set to True if the specified IP address range intersects any of the IP address ranges in the collection, or to False if the specified IP address range does not intersect any of the IP address ranges in the collection. If the call is unsuccessful, an error is raised that can be intercepted by using an error handler.
