An event can being raised only from the declaration space in which it is declared. Therefore, a class cannot raise events from any other class, even one from which it is derived. An event can only be used in the declaration space (class) it declares. Therefore, it cannot be thrown from any other class, even if the class is the inheriting class of the class in which the event resides. So how can we trigger the events in the base class and giv

debugging DLL When there will be a thing more annoying, is the DLL loaded address is not very fixed (the default setting of the DLL base is always 0x10000000, multiple DLLs with the base address is loaded, the following will definitely be relocated), this gives a lot of debugging when the comparison results caused some trouble, There are two ways to solve this problem.Method One: Directly modify the DLL fil

1. What is an interface?A: The interface indicates a group of function members (or methods) without the reference type of the members. This sentence has two meanings.First, the interface includes a group of function members but is not implemented.Second, the interface is a reference type. 2. What can an interface do for us?A: You can use the interfaceImplement Multi-inheritance.Because we can only inherit one base class, but we can inherit multiple

time complexity of the Search Algorithm Based on comparison is O (logn ). Such as semi-query, balanced binary tree, and red/black tree. However, the hash table has an O (c) linear query efficiency (in case of no conflict, the query efficiency reaches O (1 )). Let's take a good look at it: Is there a perfect combination of hash table ideas and bucket sorting? Base sort The above problem is the sorting of multiple keywords, but this method can still be

derived classes cast to base classThis address: http://blog.csdn.net/caroline_wendy/article/details/24268821in the case of polymorphic use, A pointer to a derived class or a reference to a pointer or reference that can be converted to a base class, that is, pointer to base class can point to base class part of a derive

directives, even though their advantages are far greater than disadvantages, making programming easy and efficient. iv. ExtensionSuddenly thought of C + + polymorphism, a phrase "assign a pointer to a subclass type to a pointer to the parent class type," polymorphism is implemented through a virtual function. The principle of the virtual function and its related content, the detailed understanding will not elaborate.My simple understanding is that there is a

The substituted base attribute refers to the number of substituted bases on the selected atom. In Chembiodraw software, a substituted base is defined as a non-hydrogen atom connected by any key. Instead of cardinality the atomic property allows you to specify the number of keys on an atom in the target structure, including those that the query structure has drawn. This tutorial will take the substitution

Many of the same questions that have been asked in the course of a previous tour are how to effectively remember the experiences and methods that are commonly found in working or in books or interacting with netizens. Said often in the work met some problems déjà vu, but can not think of the previous solution, is very distressed. In fact, this is everyone will encounter, not a personal problem. Especially for our network management of this industry, involved in a very wide range of knowledge, ca

Access | Data in writing data access layer code, always have to write on one side of the writing: read the database connection string, establish the database connection object, open the connection, create a Command object, create a data adapter, create a dataset, fill the dataset, close the connection. This kind of duplicate code writes one or two times to be OK, writes many to be unavoidable to have some annoyance. After summarizing the previous code, decide to refactor the code for the data me

We know that in C #, inheritance allows a base class with common data and methods to be widely used to reduce the amount of code, so that derived classes have all members of the base class (except constructors, etc.), and we can naturally use the members of the base class through derived class instances. So how do we use base
