modules.
Figure 2.1 implement the module as a group of concerns
By identifying system requirements and implementation, we can divide these concerns in the module into core concerns and cross-cutting concerns. For core concerns, the modules that implement these concerns are independent of each other. They fulfill the business logic required by the system, which is related to specific business needs. But for the log, security, persistence and other concerns, they are the common needs of the b
The writer is Gavin McLeod, a hardcore web geek trapped in the "World of Warcraft" video. The article lists 15 syntax highlighting tools that help developers quickly encode and optimize code, each with its own features. (the following are compiled content)
Developers and stubborn code geeks know that Code Syntax highlighter (hereinafter referred to as the "Code Syntax highlighting tool") is a form of level two notation that makes it easy to write in a structured language or markup langua
(i) three-color principle
In the physics class in the middle school we may have done the prism test, the white light through the prism is decomposed into a variety of color gradually transition of the color spectrum, the color is red, orange, yellow, green, green, blue, purple, this is the visible spectrum. One of the eyes of red, green, blue is the most sensitive, human eyes like a three-color receiver sy
By default, the WPF program's startup way specifies Starturi in the XAML of the app, and then the IDE automatically helps us generate a main method and then starturi the window specified in the new one out and serves as the main window for the application, but we composite Application Guidance for WPF (3)--Creates the first composite WPF application (if you do not understand how prism is started, it is recommended that you read) to change this way:
. For core concerns, the modules that implement these concerns are, in general, independent of each other, and they complete the business logic required by the system, which is related to specific business requirements. For the concerns of logging, security, and persistence, they are the common needs of business logic modules, which are distributed throughout the core concerns. In AOP, such as these modules, are called crosscutting concerns. The key to the application of AOP crosscutting technol
= (R2∗H−13H3) | R0=23r3 \frac{1}{8} V = \int_{0}^{r} (r^2-h^2) DH = (r^2*h-\frac{1}{3}h^3) |_{0}^{r} = \frac{2}{3} r^3Integration is too complex, we use a similar method in elementary school mathematics, assuming that this 1/8 volume is locked in a square with a side length of R, the extended section intersects with the cube, you can get the area between the cube and the cylinder intersection is H2 h^2. In addition to consider a bottom for the side length of the square of R, high for the four py
, where in fact should be "synthesized."
When it comes to synthesis, it should be said that the aggregation (Aggregation), which describes the relationship between the whole and the local, the synthesis is actually a "strong" aggregation, which has the same life cycle as the local, "holds" the local "object", and aggregation is only "hold" a local "pointer". For example, people and brains are synthetic, and cars and engines are aggregates, and modified cars can be replaced with better engines,
highlighting can also help developers quickly find bugs in their programs. For example, most editors use different colors to highlight string constants. So it's very easy to see if the separator is missing because it's different than the other text colors.
There are a variety of syntax highlighting tools that can be formatted and highlighted according to different programming languages. Whether it's an HTML page or a php,ruby,python or an ASP. In this article, we'll introduce the 15 best code
magnification of the refractive index of the magnifying glass, This way we can see through the magnifying glass some of the edges of the object has a true refraction effect, I believe in daily life you must have encountered these conditions. In fact, the refraction effect is very simple, in fact, is the original image of the R,g,b channel separate, and then to them using the magnifying glass we said earlier, and the magnification of these magnifying glass to make a little adjustment, such as 1.
effect of half the height of the piece chassis on the code. It is not difficult to find out the vertical axis of the center of the pawn chassis. And the position of the pawn Chassis Center is exactly the most wide part of the piece. So you can find the most width of the pieces of the vertical axis of the chess Pieces Chassis center ordinate. This gets rid of the dependency on the configuration file, allowing the code to function on any phone.
The second is for the Square Center coordinate posit

The next N lines each contains a integers, giving the (x, y) coordinates of the vertices of the convex polygon in Counte Rclockwise order. The absolute values of x and Y is at most 1 000. Assume that the tank have a positive capacity, and you never pour more water than the tank can hold.
Output

Some time ago I met someone ask me, in the prism, can put the module information in the XML file. This nature no problem, we do a modulecatalog of their own, but I have not done, today is just a simple realization of a moment, interested friends can refer to.
Why to divide the module, this of course has many advantages, such as independent development, independent testing, independent loading, and there is no direct reference between the modules, the
WPF Quick Start series (8) -- MVVM Quick Start, wpfmvvmI. Introduction
This section describes some of the core content of WPF, including the WPF layout, dependency attributes, routing events, binding, commands, resource styles, and templates. However, a good programming framework (WVVM) has also been developed in WPF. MVC has been developed on the Web Side and MVVM has been developed on the WPF client, among them, VM is equivalent to C (Control) in MVC ). On the Web side, Microsoft developed an

based on different categories. This function helps you to write structured languages, such as programming languages and Markup languages. syntax error display for these languages is different. Syntax highlighting does not affect the meaning of the text itself, and can well meet people's reading habits.
Syntax highlighting also helps developers quickly find errors in their programs. For example, most editors highlight string constants in different colors. Therefore, it is easy to find whether de
design for the application is relatively independent, and it is very easy to replace the uidesign ("whatever you want" to design your interface ). At the same time, when the UI and functions become increasingly loosely coupled, the functional testability is getting stronger and stronger.
Common open-source MVVM frameworks
Based on the structure separated by the front-end XAML of WPF and the back-end code, MVVM is the best design mode favored by WPF applications. There are also many MVVM mod
