Two Worlds unlimited brush method

In two world, killed the strange light is not refreshed, but as long as these strange in the left one, then load the next map (there read the disk symbol) when all these strange refresh, and the number of equipment random. Hatred with strange equipment from fixed so infinite, experience, money not an issue (provided that spend unlimited time).

Recommended Practice:

1, to find a group of criminals;

2, kill the last one left;

3, sent back to the city refuse (to read the disk tag appears, select a city far point);

4, repeat the process.

To note is. Archer when the equipment is very dangerous bad, as far as possible till they have killed. Strange hatred of the limited distance, you will not chase you Paoyuan up. Blame the equipment and your level and then synthesized more junk equipment also nb. Check with the stone to use when the mobile carrier, and sometimes if you put the stone and the culprits may appear too close to refresh you after the robbers did not take the initiative to attack the situation (and your grades may also be relevant. I have been in a long time.)

ps: personally feel is the easiest bows together, and now all over the world more boring brush, the caution be used with caution.

VC + + dynamic link library (DLL) program in layman's language (1)

1. Introduction

First to set out the DLL (Dynamic Linkable Library) concept, you can simply the DLL as a kind of warehouse, it offers you some of the variables can be used to use, function or class. History of the development in the warehouse through the "no library - static link library - Dynamic Link Library" era.

Static link library dynamic link library is shared with the way the code, if the static link library, whether you are willing, lib of the instructions are generated directly included in the final EXE file in the. However, if the use of DLL, the DLL not be included in the final EXE file, EXE file when the implementation of "dynamic" to quote and unload the DLL and EXE file independent. Static link library and the dynamic link library, another difference is that the static link library can not contain other dynamic-link library or static library, but also in the dynamic link library can be further contain other dynamic or static link library.

Dynamic link library, we must develop the following concepts:

(1) DLL's compiled with a specific programming language and compiler independent
Follow the convention of the DLL as long as the interface specification and the call mode, DLL written in various languages can call each other. For example, Windows provides a system DLL (which includes the Windows-API), in any development environment can be called, never mind its a Visual Basic, Visual C + + or Delphi.

(2) dynamic link library can be seen everywhere
We are in the Windows directory under the system32 folder to see kernel32.dll, user32.dll and gdi32.dll, windows most of the API are included in the DLL. kernel32.dll function in the main processing memory management and process scheduling; user32.dll function in the main control of the user interface; gdi32.dll in respect of the function is responsible for graphics operation.

Programmers are generally similar to MessageBox function used, in fact, that it is included in the dynamic link library user32.dll. This shows that DLL is not unfamiliar to us.

(3) VC classification of the dynamic link library
Visual C + + supports three DLL, namely the Non-MFC DLL (non-MFC dynamic libraries), MFC Regular DLL (MFC rules DLL), MFC Extension DLL (MFC extension DLL).

Non-MFC dynamic libraries do not use MFC class library structure, the export function for standard C interface, can be written in non-MFC or MFC application that calls; MFC rules DLL contains a class that inherits from CWinApp, but no message loop; MFC extension DLL using MFC to create a dynamic link version, it can only be prepared to use MFC class library calls the application.

As this lengthy, more content will definitely need to read this article on matters related note, the following questions and answers given in the form.
Q: What are the contents of this paper to explain?
A: This paper describes all aspects of DLL programming, to completion of this DLL should be able to have a more comprehensive grasp, and can write most of the DLL program.

Q: How do see this?
Answer: This explanation of each topic are included with the source code routine, with the text can be downloaded (each project by WINRAR compressed). All of these routines written by the author and debug by VC + +6.0.
Certainly not the readers understand the ultimate goal of this article, readers should be hands-on practice to really master the subtleties of DLL.

Q: What kind of learning this basic knowledge?
A: If you master C, and generally control the C + +, to understand that the knowledge of MFC, you can easily read this article.

2. Static Link Library
To explain the static link library is not the focus of this article, but the specific DLL before explaining, through the example of a static link library to help us quickly establish a "library" concept.

Figure 1, a static link library

Figure 1, in a VC + +6.0 in the new name for the libTest the static library project (click here to download the attachment in this project), and New lib.h and lib.cpp two files, lib.h and lib.cpp The source code is as follows:

/ / File: lib.h
# Ifndef LIB_H
# Define LIB_H
extern "C" int add (int x, int y); / / declared as a C compiler, the external connection function
# Endif

/ / File: lib.cpp
# Include "lib.h"
int add (int x, int y)
return x + y;

Compile this project to get a. Lib file, this file is a library, add the functionality it provides. The header files and. Lib file to the user, the user can directly use one of the add function of the.

Standard Turbo C2.0 in the C library functions (we use the scanf, printf, memcpy, strcpy, etc.) came from such a static library.

Here take a look at how to use the library, where the work of the project in libTest a libCall new project area. libCall project contains only one main.cpp file, it shows a static link library for calling the method, its source code is as follows:

# Include
# Include ".. lib.h"
# Pragma comment (lib, ".. \ debug \ libTest.lib") / / specify the connection with the static library
int main (int argc, char * argv [])
printf ("2 + 3 =% d", add (2, 3));

Static link library call is as simple as perhaps we use every day, but we do not understand the concept. Code # pragma comment (lib, ".. \ debug \ libTest.lib") means that in this paper generated. Obj file should be connected together with libTest.lib.

If you do not specify # pragma comment, you can set VC + +, as shown in Figure 2, choose tools, options, directories, library files menu or option, fill in the library path. Red circle in Figure 2 plus some added libTest.lib our path to the file.

Figure 2 is set in the VC library path

Examples of the static link library at least let us see how the library functions going on, they come from. We now have a vague understanding of the following:

(1) library is not a monster, the preparation of libraries of procedures and the preparation procedures generally little different, but libraries can not be executed;
(2) library provides to other procedures that can be called the East, another program to call it must be some way of specifying that it should be called.

From the above analysis of the static link library on the library get muddled concept can be extended to the dynamic link library, dynamic link libraries and static link library and call in the preparation of the different reflected in the library on the external interface definition and call a slightly different way .

3. The library and view the debugger

In specific detail into the various DLL's before, it is necessary to debug and view the library method look description, because the next section, we will be faced with a large number of examples of projects.

As the library file can not be executed, thus pressing F5 (start debug mode execution) or CTRL + F5 (run) the implementation of, its pop-up dialog box shown in Figure 3, requires users to enter the path of the executable file to start the library execution of the function. This time we enter the call the library path of EXE file can be debugged on the library, and its general application debugging skills and debug the same project.

Figure 3 library debugging and "Run"

The practice is usually better than debugging means that the library project and application engineering (call the library project) located in the same VC workspace, application engineering for debugging only, call the library at the application engineering function to set the statement Department breakpoint, execution, press F11, so step into the library function. Section 2 of the libTest and libCall project to put the same work area, the project structure shown in Figure 4.

Figure 4 library project and call the library project to debug into the same work area

The testing method and the static link library dynamic link library in terms of the same.鎵?互鏈枃鎻愪緵涓嬭浇鐨勬墍鏈夋簮浠g爜涓兘鍖呭惈浜嗗簱宸ョ▼鍜岃皟鐢ㄥ簱鐨勫伐绋嬶紝杩欎簩鑰呴兘琚寘鍚湪涓?釜宸ヤ綔鍖哄唴锛岃繖鏄瑪鑰呮彁渚涜繖绉嶆墦鍖呬笅杞界殑鐢ㄦ剰鎵?湪銆?br />

"Jingdong model" kept short board

The data from Analysys International show that in March this year, sales of Jingdong has more than 200 million yuan, even more than the traditional two-Dangdang and excellence Amazon. However, in direct sales where the profit is not high, Jingdong want to further enhancement of the non-profit directly above the breakthrough. Meanwhile, Jingdong have higher sales, but there are fewer problems in the number of users.

The second half of last year, e-commerce once again become the focus of all Chinese hot one. Analysys International in the "first quarter of 2009, China's B2C online retail market, quarterly monitoring," said in the first quarter of this year, China's B2C market reached 3.496 billion yuan. Taobao C2C market, compared to a dominate, starting earlier in the year because of China's B2C market, the entry of Jingdong Mall is more complicated.

With rapidly expanding 3C products and home appliances of Jingdong Mall recently announced that it will fully expand its investment in the appliance field, is proposed line from the microwave, hair dryer and other small appliances extends to refrigerators, washing machines and other large household appliances.

If Dangdang, excellence is to build a Wal-Mart online, and Jingdong choice is more like a copy via the Internet Suning success.

High per capita consumption of hidden

According to the China Electronic Chamber of Commerce quoted Deputy Secretary-General Lu Renbo statistical data, said home appliance business through the Internet last year, online mall number of commodities has exceeded 1,000, market size is about 20 billion yuan, accounting for household appliance market, 2% of total sales. The year 2009, the market scale is expected to exceed 800 yuan to 100 billion yuan.

As we all know, home appliances, especially large appliances are usually priced higher and lower sales profits. Jingdong Mall in March to break 200 million yuan of sales, for example, can be interpreted as "50 million people, each spending 4,000 yuan." The traditional B2C model is "4000 million people, each spending 50 yuan."

According to the current user's view of the majority of Jingdong, buy appliances online "prices lower than the mall," even to the store many users choose the right model, then to the on-line orders. Can be a very obvious problem is that such a giant compared to Suning, it is difficult to imagine the "new channel" Jingdong Mall from suppliers for lower purchase price. Even low-cost virtual store can be balanced to some extent, the spread between the two channels, but if can not find in other profit strong support, it is difficult to imagine Jingdong's "cheap" to last.

It is easy to think of another Chinese e-commerce in the area of a "martyr" E state. Many years ago, E China "to buy enough for 10 yuan to send Coke" approach to a large extent, allow users to realize the benefits of e-commerce, but unfortunately, you feel the benefits have not become a sufficient condition for the success of E state.

"Suning model" of imitation problems

Whether Jingdong mode or traditional e-business models, the source of profits generally fall into three categories.

"ABC profit by jargon is called." Certain e-commerce executives, said, "A profit is the profit generated by selling direct. B profits and sales is directly related to the non-profit. Generally channel obtained from the manufacturer business sales rebate or incentive. C profits and sales is directly related non-profits are usually embodied in the supermarket goods shelves fees. in the traditional retail industry, the larger shopping centers, B and C the profit contribution margin the higher. so you often can see some of the market in the promotional activities, sales of commodity prices than the manufacturers Chu Huojia even lower. This fact is to share with B and C to subsidize the profit A profits are. "

Suning Appliance stores have the traditional line under the interpretation of this model thoroughly, and to some extent Jingdong thinking very much in line with them.

The problem was arising. In the retail chain, suppliers and channel business has been a contradiction. When the channel business is strong enough, suppliers often have to ship price, channel management strategies on both the policy and even some adjustment. Bearing that in mind, if not strong commercial channels, they are very difficult to win from suppliers lower shipping prices, is also almost impossible to obtain in the leading position in procurement negotiations. This is the "Jingdong mode" now have to face the biggest challenge.

"Last year, the home network market share is still only 2%." The anonymous senior said, "even speeding up, we can hardly imagine that online channels can be Suning day as strong."

Difficult to break through the "B + C"

The data from Analysys, said the first quarter of 2009, China's B2C market is 3.496 billion yuan, C2C, compared with 44.071 billion yuan.

"As a whole, for various reasons, products sold through the network platform, whether B2C or C2C, its price is slightly lower than offline stores." Dangdang Chenteng Hua, vice president, said, "This is the e-commerce features, as virtual shop do not take a lot of line shop requires affordable cost. "lower the price of the original cost of the corresponding lower natural, but it also indicates a problem is that profit in the A, e-commerce and traditional retail practice the differences are small. "Lower cost" can not actually e-commerce businesses to secure the number of new profits. So in order to achieve a breakthrough in the profits, B and C profit is the profit of a breakthrough where e-commerce.

So, is the impact of 4000 million people are more likely to break through, or only affect the 50 million people?
