public void Remove( 
   int index
)

'Declaration

Public Sub Remove( _
   ByVal index As Integer _
)

'Usage

Dim instance As IPFilters
Dim index As Integer
 
instance.Remove(index)

public:
void Remove( 
   int index
)

Parameters

index: Zero-based index of the IP filter to remove.

This function toggles the "allow" permission for the specified IP filter and combines the new entry with the existing collection. This has the effect of deleting the entry. 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.
