VB Programming Grade Enquiry System .

Add 2 buttons, 2 textboxes, 1 listbox, and you can't go wrong.

private sub command1_click()randomize

for i = 1 to 10

x = int(rnd * 71) -35)x

next i

end sub

private sub command2_click()val( +val(

end sub

private sub list1_click()static i

if i mod 2 = 0 then

else =

end if

i = i + 1

end sub

I have a grade check system designed by VB programming.

If you develop a query system alone, there is more content involved, common technical support, server support, ** support, etc., but also need high development costs, general schools and small enterprises are unable to support this cost, but also need a special person to maintain, so the independent development of a query system, for schools and small enterprises is not realistic! In fact, schools and enterprises can use the easy check score to generate a query system, and the above development projects do not need it, as long as the content that needs to be queried is made into excel and uploaded toEasy to check scores, it can be generated, and it can be done in 3 minutes! There is no need for special maintenance in the follow-up, and teachers can build a management background of their own school, which is very convenient!

You can try it

Create one in access with a Northwen database instance or create your own

1. Start the access empty database and name it "Student Files".

2. Create a table, if there is excel data, you can import it directly or build a table in the design view, field name: student number, name, gender, date of birth, home address, etc. Take the name "Student Profile" as for the record, and enter the situation of several people yourself.

3. Create a table named "Student Grades", and the field names are: Student ID, Course A, Course B, Course C, Course D, Course E, etc. As for the record, enter the situation of several people yourself.

4. Create the corresponding query. For example, in the design view, drag the student ID of the "Student Profile" to the student ID field of the "Student Grade".

The SQL statement is SELECT Student Profile. Student ID, Student Profile.

Name, [Student Grades]![Course A] + [Student Grades]![Course B] as Overall Grade from Student Profile Inner Join Student Number on Student Profile.

Student ID = Student Grade. Student number, you can check the student's grades.

5. Build a form (design view) to build some description labels and some function buttons: the click event of the button calls the corresponding macro event (or use vba**) (query, etc.), named "main form".

6. Create the corresponding macro (or use VBA**), there are functional prompts in the macro, such as openform (open form), opentable (open table), requery (open sql query on behalf of others), close (close), quit (exit) and so on.

7. Start macro in the main form: use openform"Main form", the macro name is autoexec.

A simple database is built, open the database under Windows, and you can enter the main form of "Student Profile". There are a lot of access functions, and one or two sentences are not clear, so look for this textbook.

System requirements analysis and feasibility analysis.

This chapter mainly introduces the overall design overview of the system, the factors that need to be considered in the design, the analysis of user requirements and design requirements, the system design and its feasibility analysis.

Design Brief. The computer management information system of performance analysis and statistics is developed for the performance management of school teaching classes, which mainly takes the front-end application of performance management and performance statistical analysis as the core, provides a simple and friendly user interface for performance managers, reduces the cumbersome and error of manual processing, can easily carry out performance inquiry, entry, modification and deletion, and can automatically carry out some routine data statistics and analysis, so as to improve the work efficiency of performance managers.

Considerations: According to the needs of practical application and the characteristics of the statistical program itself, I believe that the following aspects should be paid attention to in the design process:

Practicability. According to the practical feasibility of the scheme proposed in line with the mode of performance management of performance managers, the results can be well managed, so that the system can meet the requirements of performance management and general statistics and analysis of results, and give full play to the role of the system in practical work. The system interface is friendly and the staff operation is simple.

Reliability. It is necessary to ensure the stability of the system and the reliability and safety of the data. The system must have strong fault tolerance and complete security and confidentiality mechanism.

Stability. It should be achieved from the high quality of the hardware and the perfection of the software. The design of the software system, as well as the application database and software development language, must be based on the daily operation and stability of the system.

Requirements analysis. There is still a lot of information on the Internet for Sanqi graduation project, if you need it, you can go and see it, I hope it can help you.
