Only a public derived class is a true subtype of the base class, and it inherits the functionality of the base class completely. There is an assignment-compatible relationship between the base class and the derived class object, because the derived

This article will explain how to manipulate LUA arrays and string types in C + +, as well as how to store the LUA State (registry and Upvalue) in C + + functions, and Registry is useful when using C + + custom types. You can easily specify metatable

Recently encountered a need to implement export PDF file, the Internet to check the following code summary of the code, you can successfully export PDF file. You need to download a itextsharp.dll on the web before coding, this assembly is a must.
