network is configured to require verification, the SNMP slave agent authenticates the group name and the IP address of the Management site. If the authentication fails, the SNMP proxy will send a trap message for authentication failure to the management site (see later ); Protocol Data Unit (PDU ):PDU indicates the Message Type and related parameters of SNMP. 2.

we only write two constructor functions of this class to return all data sets in the table, because the table inherits dbbaseclass. Similarly, we will write another subclass: topic, which is the abstraction of the table topic. Public class topic: dbbaseclass{Public topic (): Base ("topic "){}Public topic (string tablename): Base (tablename){}} Like a user, this class also provides the ability to return all datasets. During subclass instantiation, different types of objects are returned i

The condition for setting the hidden column in the B3 lattice is value () = null. If the input node is a leaf node in this province, name = null, and column B is hidden and not displayed. Column C to column F is the right half of the report. The kpi statistical value corresponding to ds2.name is displayed. To implement the report f

I once tried this and wanted to record it. I don't know if it is a good implementation method (I wanted to write the best implementation method, but it would be nice to think of these absolute words );This includes that two Ds tables have only one table, and their columns are the same. Each table has a unique column ID, but their datasets are different, I want to know that every ID of one of the DS tables appears in another DS table. Dataview dtv1 = Ds
