Computer room charge System--the Power of information science

computer room charge system--the power of information science

Engine room has been dragged from the beginning to now has been a long time, feel that they are not much, and go back to see three

Layer, review the design pattern. Looking at Zhenhua, every step of learning good practical, progress duang up, I really

That's a shame!

Now that the network is so developed, the information is so full, but also worry about no giants? The key is to take the time to

Do, remember just came to improve the class, we learn O-easy video, content is to teach us how to better use

Search engines, which have learned, advanced search, image search, sound search, documents in various formats and so very

A variety of technologies to facilitate our search, so that we can quickly and accurately find the information we want later we understand

, met will not go online check, so we slowly have this consciousness, slowly rely on the network this

Giants, all say we have to stand on this shoulder of giants, indeed have it, many of our problems have been solved.

In fact, the essence is, will we encounter problems, let everyone do, people more powerful? Besides, there are people outside, mountain

There are mountains outside, where we are better than our great people.

This time to do the computer room charge system, let me more aware of the power of the network, the power of information technology. Front do

The student management system has the source code, we have what will not be able to take the source code to refer to, can not understand the source code

On the internet to find out, can be very simple to solve the problems we encountered. But this time, the computer room charge system

We use the knowledge we have learned to do. From the start of the analysis of the computer room charge system, to build data

Library, and then to the current writing program implementation functions, as well as the subsequent debug release and so on a series of steps. Do the computer room collection

Fee system, there is a feeling of being deterred, and when it comes to seeing what functions, the feeling deepens, but

Do it, but there is no, because information technology to help me a lot of busy, I have a network around, there is this giant.

In the process of refactoring, do before think is the problem of have, build table, different level of user login, student on machine, card

Checkout, export Excel form, normal down machine, force down machine, date time DTPicker control use

(It was not known at the time to have this control), combined relationship query, Checkout tab (not known at the time), report,

Print Preview, print and so on some superficial problems, these problems, some don't know there is this thing, some

is to look at the trouble complex. So the first feeling was the trouble and couldn't do it.

In the process of doing, have encountered a lot of problems, such as the data type of the table in the database and VB program number

According to the type of mutual conversion, consistency, etc., as well as the main form of mutual display, position adjustment, etc., the various tables in the checkout

The consistency of data in the database, there are no data in the consideration and so on, a lot of details of the problem.

In this process, the problem is many and many, but with the help of the network, one problem leads to the solution,

Some have found the former brother Siang of the blog, some have to find out with more Daniel on these problems of the solution, but also

There is learning more essential knowledge, these things, are from the Internet. One of the things that impressed me most was:

The export of the 1,excel table, at that time there was no thought, by looking, to see some solutions at night, but

For me the most help or brother Siang the blog will mshflexgrid table data into the Excel method;

Some of their own research in reading blog)

2, the report of the study, in the implementation of the day checkout and weekly checkout, the most headache is the use of the report, because it was not seen before

A The first is to search Tangchanghai Brother Siang's blog and nine of the Kang Lixian's blog, although written very good, but

The feeling is only to understand the macro (but this direction is very important), more importantly, they are downloading

Grid++report Report Designer, after the continuous practice of use, and constantly look at the help, only slowly learn to use it.

This is two pieces of my completely unfamiliar territory, but under the guidance of the computer room charge system, with the help of the network, I contacted

them, understand them, and use them, which may be called, learn in practice, grow in practice

it.

Of course, there are some other problems, are beginning to think complex, in fact, not so difficult, in the network and brother Siang Division

Sister's reminder, will be very easy to solve, for example, date Time control dtpicker use, print preview,

printing function and so on some, but they have not touched, but they are very simple. At that time through a search,

Network to give hints, coupled with their own experiments, a lot of problems solved.

Summary:

In the computer room system and other learning processes, I am more aware of the importance of information technology, he can help us

Solve the problem we can't solve, he can give us a clear hint on the way forward, he can change

Our life has been a mentor, it helps us, we learn from him constantly, progress

, accumulate, Grow ~ ~ ~

Although I now have a lot of specialized courses, but, or their own "heart", if they want to take the time to take,

The intention to accumulate, it is not impossible, believe in themselves, love themselves, around there are so many excellent pass

Permeability, there are brother Siang, more teachers, this is not a big problem!
