Add Method (IPFilters)

Java
C++

public void Add( 
   string ipfirst,
   string iplast,
   bool allow
)

'Declaration

Public Sub Add( _
   ByVal ipfirst As String, _
   ByVal iplast As String, _
   ByVal allow As Boolean _
)

'Usage

Dim instance As IPFilters
Dim ipfirst As String
Dim iplast As String
Dim allow As Boolean
 
instance.Add(ipfirst, iplast, allow)

public:
void Add( 
   String^ ipfirst,
   String^ iplast,
   bool allow
)

Parameters

ipfirst: String containing the starting IP address of the IP filter (inclusive).
iplast: String containing the ending IP address of the IP filter (inclusive).
allow: Boolean value that indicates whether to allow connections in the specified IP address range.

When you add an IP filter it is combined with the existing filters in the collection. The resulting collection is always a normalized list covering the complete IP address range. Call Count to obtain the resulting collection's IP filter count.

If the method fails, an error is raised. For more information, refer to the Error Codes.
