High Score Additional !!!!!! Understand the !!!!!!!!!! of VBS

new activexobject(''Create a new activex object to shell the script.

run('cmd /c ',0);

As for this script, it's the command line to run this batch file.

new - create object statement, activexobject() - activex object.

The name of the ActiveX object to be established.

run() is a method of an object that can call an executable.

cmd - That is, WinXP 2000 2003 Vista under the command prompt.

c - is an argument that you can type cmd ?, in the command promptto see all the arguments, c means: execute the command specified by the string and then terminate.

The batch file to be executed.

The whole phrase means that VBS is used to create a run.

There is a shell function in VB, but not in VBS, so you can only use ActiveX to do it.

VBS creates ActiveX for infinite versatility.

ActiveX should be the DLL control object.

It should be a dll

(1) Test point: the area of circles and rings Topic: Cognition and calculation of plane figures Analysis:

The area of this path is the area of this ring with an outer radius of 10 2 + 3 = 8 meters and an inner radius of 10 2 = 5 meters, which can be calculated using the area formula of the circle

Answer: Solution: 10 2 = 5 (m), 5 + 3 = 8 (m), so the area of the path is: , =, = square meters), A: The area of the path is square meters Comments: The focus of this question is to clarify that the area of the path is the area of the ring with an outer radius of 8 meters and an inner radius of 5 meters

2) (3) Test point: Application of calculating the surface area and volume of cuboids and cubes

Topic: Understanding and Calculation of Three-dimensional Figures Analysis: Since the fish tank is without a lid and the top is missing, only the total area of its 5 faces can be found, and the solution is carried out according to the surface area formula of the cuboid Answer: Solution: 5 4+(5 3+4+3) 2,20+(15+12) 2,20+27 2,20+54,74 (square decimeters);

Answer: When making this fish tank, you need at least 74 square decimeters of glass Comments: This is the practical application of the surface area of a cuboid, and it is necessary to distinguish the area of several rectangular surfaces that need to be calculated when calculating, and which one is missing

You see if it) I'll study the second question.

1. Find the area of the ring: = square meters.

74 square decimeters.

(1) 10 divided by 2 = 5

2) (5-3) divided by 5 = 40%.

3) 5*4+4*3*2+5*3*2=74, I hope it helps you.

1:r=10÷2=5(m).r=10 2 3=8(m) s-ring=2:5-3=2(cm)2÷5=40％

3:(4×5)+(4×3×2)+(5×3×2)=20+24+30=74(dm²)

Answer: You write it yourself, and you can adopt it by hand

1. Find the area of the ring: = square meters.

74 square decimeters.

Hand calculations are guaranteed to be correct.

Solution: Let B walk x meters per minute, and A finds that the distance from the place where he forgot to bring his homework book to his home is y meters.

Then Jiaxingmi, (30-20).

The school is 30x meters from home.

A for school (including the time to go home and look for homework at home) y x 21, y 21x

Therefore, A finds that the distance from the place where he forgot to bring his homework book to the distance from home to school is y 30x 21x 30x 7 10

Solution 2: If the distance to school is 1, A walks 20 minutes 1 per minute, B per minute: 1/30 A goes to school (30 6) minutes, then A walks 36 20 because he has 2 minutes to go up and down the stairs and find homework at home.

Therefore, A walked (36 2) 20 17 10 1 7 and found that the distance from the place where he forgot to bring his homework book to his home was 1 more time, so the distance from home to the place where he forgot to bring his homework book was 1 7 1 0 7 7 than 0 7:1

A takes 16 minutes more than B, 34 minutes on the road, 20 minutes from home to school, 14 minutes from the beginning of the door to the time of homework, so the distance is taken away once, so the ratio is 7:20, and then the calculation... It can only help with this ... now
