I. Introduction These two chapters mainly introduce some popular object-oriented models and some OOAD principles. The book only mentions the tip of the iceberg of these concepts, it is a very long process to grasp these concepts and principles. It may be difficult to fully understand these concepts and principles over the past two or two years. Therefore, I will not explain them too much here, I need to think about it myself.These concepts mainly include: Common design modesRecommended learni

Today, I learned how to delegate this chapter on msdn. Although I have seen some webcast videos about the entrusting party and some related introductions on the internet, I have never figured out what the entrusting is. Today, it took me a day to finally unlock her secret. Delegate. The English name is delegate. You can translate Chinese characters into representatives and act as proxies. As the name suggests, the delegate and the method assigned to

Smartclient (Smart Client) note 4, mainly learning vs2005 multi-threadProgramDevelopment support, Lecture 7 in the webcast series: use multithreading to create high-response Smart Client Applications. program developers should know that every program running on the system is a process. each process contains one or more threads. the process may also be the dynamic execution of the entire program or some programs. A thread is a set of commands or specia

(According to the msdn webcast courses) Object-oriented solution solves the problem of System Abstraction without compromising the system performance. However, in some special applications, because the number of objects is too large, adopting object-oriented will bring an unbearable internal overhead to the system. For example, metadata and other objects in graphics applications, character objects in word processing software, etc. If the solution i

The combination mode uses a tree structure to implement ubiquitous object containers. It converts a complex one-to-many relationship into a simple one-to-one relationship, so that a batch of objects can be processed in a consistent manner, make the customerProgramYou do not need to care about the specific imple

(According to the msdn webcast courses) Coupling directly determines the behavior of the software in the face of changes. When the coupling is tight, when a module changes, the relevant modules must be changed accordingly; the dependency is complex. When loosely coupled, the module is easier to replace or change, while other related modules can remain unchanged. Simple dependency (small dots represent interfaces) Do not be limited to a fixed

(According to the msdn webcast courses) Objects in different States often perform different actions. Usually, we can use the switch... Case statement to solve the problem. However, if the state changes frequently, this must cause tight coupling between the object and the object. Of course, we should not deliberately adopt the design pattern to use the design pattern, because In a single case, the adoption of the model may complicate the desig

(According to the msdn webcast courses) Mode classification: Purpose: Creational: Responsible for object Creation Structural: A combination of processing classes and objects. Behavioral: Responsibility Assignment in class-object interaction In terms of scope: Class Mode: process the static relationship between classes and subclasses. Object Mode: process the dynamic relationship between objects. Classes in single-piece mode ensure that the cl

(According to the msdn webcast courses) Direct and indirect: For complex systems, we often add an intermediate layer during use to shield some of the less commonly used functions or simplify some of the frequently used functions, in this way, a simple and flexible method can be used to meet specific needs. For example, when a accesses B, B needs to be called once every time B is accessed. Due to the complexity of B, the call overhead is high, espec

I first came into contact with programming in high school. At that time, I introduced QBASIC programming in the course. I don't know if anyone was the same as me. after entering the University in 03 years, most of the time the contact was mainly in C. I remember that on the basis of my self-study, I often ran to Microsoft's webcast to download videos to listen to and visit csdn forums, and read blogs in cnblogs (I felt that I was still diligent when I

Using this framework does not take a long time. However, several projects are basically applied. I would like to share with you how I set up this framework step by step. It also provides a simple example for beginners. You are welcome to discuss technical issues. [I am a rookie! Sorry for the shortcomings !] Step 1: First, let's take a look at the Layer 3 in my project, MVC, spring. net, and nhib.pdf. See the following figure: First, we will give you a general idea and understanding.

GPS intermediate driver Since the introduction of GPS intermediate driver (GPS intermediate driver) in Windows Mobile 5.0Program(Gpsid), it is much easier to develop a Windows Mobile Application Based on GPS (global positioning system. The reason is that it adds an intermediate layer between the application program compiled by the developer and the GPS device, so that the developer does not need to directly access the gps device through the serial port, but access the API function provided by

Developing with Atlas Control Toolkit Program, Prepared for a long time. The main difficulty is the design of the front-end page and the interaction with the back-end.

After introducing the basic concepts of programming in the previous lecture, we will focus on some important elements in game development, such as images, player input, sound, and network. We will discuss the use of 2D/3D images, vector images and bitmap images, keyboards, mice, Force Feedback Controllers, audio formats, 3D sound effects, network protocols, multiplayer games, comparison between point-to-point (P2P) mode and Client/Server mode and other game elements.
