Advantages and disadvantages of vb
Advantages: the most prominent word is "fast", object-oriented mode, perfect control components, many tutorials, and extremely high development efficiency at the application level.
Disadvantages: It involves the development of the underlying system and network. Compared with C and JAVA, the language is not concise enough. A small audience has a certain impact on employment.
That's it in a nutshell. There are many details on the internet. Just Baidu.
Advantages and disadvantages of VB? VB's support for underlying functions and indicators is not as good as VC++
In contrast, the development environment of Delphi is better than VB, and it can be cross-platform.
But VB has a very prominent advantage, that is, the software developed is particularly small. Neither VC++ nor Delphi has written any code, and has compiled several hundred KB, while VB has only 20KB. The function of VB program, which can reach several hundred KB, is quite perfect.
Advantages and disadvantages of vb vc++ bc++ delphi VC is now mainly used for bottom development and hardware-driven development.
When developing database management systems such as ERP, VC is rarely used, because the cost of developing ERP with VC is too high, which refers to the labor cost, while C++ develops ERP slowly and is difficult to maintain.
Relatively speaking, delphi C# is different. Developing ERP has the advantages of high speed, low cost and high natural profit.
For example, if you start a software company to develop an ERP system, it takes 8K/ month to find a C++ engineer and 5K/ month to find a delphi engineer, and the personnel are easy to find and the development speed is fast, so you definitely don't need C++ personnel.
Forget VB. Things that can't get on the table, even a standard DLL can't be written before, but now it's unclear. But VB is still possible.
BC++ combines the advantages of C++ language with the free and easy of DELPHI, which is very handsome.
But C# is very popular now. The birth of C # is mainly aimed at java, which has a virtual machine and C # has a platform.
And many people choose C# because of Microsoft, which programmer will find a company with an uncertain future.
What are the advantages and disadvantages of vf and vb? Vb code is simple and can realize small applications. But the online implementation is poor and not as powerful as C#
Advantages and disadvantages of bbs forum website
Including text and pictures, photo types.
Excellent: there are new posts and photos every day, and the user participation is high.
Lack: There are too few columns in the forum, which only meets the wishes of the sponsors. The narrow information space is easy to form small groups and circles, and a large number of users are excluded. Clicking on the points ranking of photos and posts will kill the website. The reason is that new information and hot spots can't compete with old information, and users always seem to be reading outdated magazines.
Advantages and disadvantages of JFreeChart: At present, the best java chart solution is powerful and basically covers all kinds of charts; Java implementation, powerful extension suite, relatively complete API, and support for multiple output modes.
Disadvantages: many classes and interfaces, long learning time; If it is output as a file or a response stream, it lacks interactive function. In order to realize the interactive function, it is necessary to use Frame or Applet, which has certain disadvantages.
Generally speaking, JFreeChart technology can be used to customize various charts according to requirements and realize various human-computer interaction functions in some way. JFreeChart is an open source charting technology based on java, which deserves further study.
Advantages and disadvantages of NUKE NUKE is recognized as the strongest synthetic software after SHAKE stopped developing, with high speed, low cost, good expansibility and high stability.
At present, the most professional nuclear forum in China is nukechina ... nuclear bomb China. They made a China version of NUKE, and the forum was officially certified. . .
Advantages and disadvantages of MIUI Hey!
MIUI V5 is by far the best MIUI. In addition to the exquisite and beautiful interface, there is a thoroughly remoulded connotation far better than the appearance, waiting for you to taste. At the same time, MIUI is not just a beautiful UI, but a huge project: 1 desktop system +5 common functions+18 gadgets +8 core applications.
The most obvious change of MIUI V5 is to redraw 1000 common application icons, and each icon adds freehand brushwork elements on the basis of simulacra. It is worth mentioning that V5 supports dynamic icons, and calendars, clocks, network assistants, compasses and weather can be displayed in real time.
In terms of calls, MIUI has a more user-friendly design: no answer for 30 seconds, * * * automatic amplification; Pick up the phone, * * * automatically weakened. It also has built-in functions such as marking strange incoming calls, preventing incoming calls from being disturbed, remembering in general, taking phone notes, recording designated contacts, and 35 innovations in short messages.
MIUI V5 also focuses on in-depth optimization of camera and photography functions, adding voice-activated camera function, which can not only shoot suspension, the moon, night scenes, but also take time-delayed photos.
Compared with the native Android4. 1 system, the standby time of MIUI V5 is doubled. For the reason of smart phone power consumption, Xiaomi said that it is mainly because the development of third-party applications is not standardized, such as quiet boot, timed wake-up, background networking and so on. MIUI V5 has been optimized in the aspects of self-starting management, networking control and alignment wake-up mechanism.

A more detailed description of the problem will help netizens understand your troubles and help you solve the problem more accurately. Thank you for supporting Xiaomi mobile phone!
Advantages and Disadvantages of FDI Xu Yisheng, director of the commentary department of China Business News, put forward a new view on the retained profits of FDI in China: the appreciation of RMB will turn China from a creditor country into a debtor country. On 20 11April1day, the state administration of foreign exchange issued the balance of payments for 20 10 under the new caliber, and revised the balance of payments for 2005-2009 by adjusting the caliber. This revision is of great significance, but it has not caused extensive discussion. The core of this revision of SAFE is to refer to international standards and bring the retained profits generated by foreign direct investment (FDI) in China market into the balance of payments. This makes the problem of retained profits of FDI, which has not entered the mainstream discussion for a long time, surface. According to the international investment position table of the foreign exchange bureau, by the end of 2009, the accumulated balance of FDI had reached 997.4 billion US dollars, close to 1 trillion US dollars. This 1 trillion dollar foreign assets in China are generating high profits every year, and most of these profits are not remitted to China, but stay in China. Because of its operation in China market, the profits of foreign direct investment exist in RMB, which has gradually become a "RMB hot money" divorced from the mainstream discussion. As for the retained profits of FDI in China, because it has not entered the official statistics, its scale is getting larger and larger, and it has become a "dark matter" for observing China's economy. As the foreign exchange bureau adjusted the balance of payments in 2005 to 20 10, this "dark matter" began to surface. The energy of "dark matter" is so great that it will change a lot of our qualitative understanding as soon as it surfaced. The scale of "dark matter" proposed by the foreign exchange bureau this time is 210 billion US dollars, or10.4 trillion RMB. The ownership of this part of funds belongs to FDI, but the form of expression is RMB. According to the international balance of payments management rules, this part of RMB funds can be unconditionally converted into foreign currency at any time and evacuated. According to the principle of this revision of the foreign exchange bureau, this revision is "according to the internationally accepted standards, the undistributed profits and distributed undistributed profits of foreign-invested enterprises are recorded in the financial account of the balance of payments for direct investment". Since both undistributed profits and distributed undistributed profits are in the form of RMB, RMB profits attributable to foreign direct investment in the balance of payments are converted into US dollars. It should be noted that, according to the data of the foreign exchange bureau, in 20 10, China's FDI inflow scale reached US$ 206.8 billion (up 42% compared with 2009), the outflow scale was US$ 21700 million, and the net inflow scale was US$ 185 1 0 billion (up from 2009) Among the inflow of $206.8 billion, the financial sector inflow was $654.38+02 billion, and the non-financial sector inflow was $654.38+09.48 billion (including the real estate industry inflow was $276.543+00 billion, an increase of 78%). The inflow of FDI in the balance of payments is much higher than the statistics of the Ministry of Commerce. According to the data of the Ministry of Commerce, in 20 10, 27,406 foreign-invested enterprises were newly approved nationwide, and the actual amount of foreign capital used was1057.35 billion US dollars (up 17.44% year-on-year). It can be found that the inflow of $206.8 billion from the balance of payments is nearly double that of $654.38+005.7 billion from the Ministry of Commerce (654.38+096%). It should be emphasized that the foreign exchange bureau's unveiling of "dark matter" is only a good start. At present, the balance of payments still underestimates the scale of retained profits of foreign direct investment. This reversal effect has actually come. How big is dark matter? In fact, because the accumulated FDI stock is close to 1 trillion dollars, its annual profit scale has exceeded the new increase of FDI annual net inflow. Is "dark matter" potentially destructive to the balance of payments security? The answer is obvious, yes. Due to the huge balance of foreign direct investment at present, its annual profit scale is enough to have an impact on China's balance of payments security. In the balance of payments, we will soon see the so-called "FDI's own net deficit effect", that is, the annual FDI inflow is less than the annual undistributed profit. This will be the beginning of the reversal effect of foreign direct investment on the balance of payments. More importantly, it should be noted that the remittance of foreign direct investment profits has increased significantly in recent years. After the appreciation of RMB is in place, it is bound to usher in the remittance of retained profits of FDI. At this time, because of its huge scale and unconstrained, it will have an impact on China's international balance of payments security. Why is the return on China's huge overseas assets so low, while the cost of external liabilities is so high? This is because China's external assets are mainly foreign exchange reserve assets, while its external liabilities are mainly high-cost liabilities such as FDI. The foreign exchange bureau only adjusted the retained profits of FDI and changed the net income of China's foreign investment. In fact, if the "retained profits of FDI are underestimated" is established, even if China's current net foreign investment is 2 trillion US dollars, the overall foreign investment income may still be negative. For various reasons, the current balance of FDI in China's balance of payments is calculated by "historical cost method". In the United States and other countries, the statistics of FDI are all "market value method". In almost all accounting statistical systems, "historical cost method" has long been replaced because it is out of touch with the development of the times, but it is still used in FDI projects in China's foreign investment position table. There are many statistical problems here. On the whole, although some foreign-invested enterprises have failed to operate, judging from the overall successful operation of foreign-invested enterprises in China, the current market value of domestic FDI is definitely greater than its historical cost. According to the historical cost method, 1 trillion US dollars of FDI has accumulated into a huge and incalculable "market value" in China, and together with its accumulated retained profits, * * * isomorphically becomes the "dark matter" of China's national balance sheet. It is very important to evaluate the market value of FDI assets, which will involve a major qualitative judgment, that is, is China the largest creditor country in the world at present? Is China still a net creditor? According to the current international investment position table, the net position of China's external assets in 2009 was $65,438 +0.8 trillion, of which FDI was valued at $997.4 billion by historical cost method. That is to say, if FDI assets are valued at $2.8 trillion according to the "market value method", then China will become a debtor country from the largest creditor country in the world. In international capital flows, foreign direct investment is usually considered to be stable and non-speculative. However, the retained profits in China's FDI system are obviously speculative. In addition, the experience of Latin American financial crisis and Asian financial crisis in the last century proves that FDI will also set off a wave of divestment during the crisis. For the security consideration of the national balance of payments, this is a "black swan" that has to be considered. In fact, in order to consider the security of China's balance of payments, it is urgent to evaluate the market value of foreign direct investment.
