classes written in one language should be able to communicate directly with classes written in another language, especially:
Classes written in one language should inherit classes written in another language.
A class should be able to contain instances of another class, regardless of the language in which they are written.
An object should be able to directly call the method of another object written in other languages.
Objects should be passed between methods.

development using C++/CLI. Reading navigation ways to learn C++/CLI There are three aspects involved in designing C++/CLI language. This also applies to all other program development languages: One is the mapping of language-level syntax to the underlying generic type system (CTS), and the second is the level selection of the underlying detail structure of the CLI provided to the program developer; The third is direct support beyond the CLI, Prov

the client reads and writes data based on the timestamp, and reads the data, writing the data to the specified STS when the cell is written. Version time is wrong, This step ensures that different transactions do not conflict when writing data, that is, the ability to provide the unlocked update data.

Introduction: This article explains in detail how to enable and use Non-default encryption types such as "Aes128-cts" in the Kerberos settings (ibm®network authentication Service). Also explains why each step is performed. This content helps the Kerberos administrator use any Non-default encryption type in the Kerberos settings.
