Using Case Select statement for beginners’ user Command Button – Visual Basic

Today I will share it to you another project in visual basic. This project is very easy to do if you know how to use Case Select statement. But if now, in this project you are going to learn using it, just follow the steps and procedures below!

The Case:

Weight (gram) Cost

0 - 50 1.4

51 - 100         2.7

101 - 250         4

251 - 500        7.5

The exceeding weight from 501 – up will be multiplied by 0.020.

In this project you are going to create a FRAME, 3 LABELS, A TEXTBOX, and A COMMAND BUTTON. Just look like the screenshot below. You can create your own if you want but if you want to follow my own work, also you can.

Don’t forget to rename your object in order your program works properly. I hope you know how to rename the object but if not you can go to Prefix Abbreviations for control names for your reference.

After you done creating those object I’ll mentioned and its looks like the screenshot above, you can go now to the coding.

To add the code, 

1. Simply Double Click the CALCULATE Command Button

2. Add the following code:

Dim Weight As Integer

Weight = txtweight

Select Case Weight

    Case Is <= 50

    lblamount = 1.4

    Case Is <= 100

    lblamount = 2.7

    Case Is <= 250

    lblamount = 4

    Case Is <= 500

    lblamount = 7.5

    Case Else

    lblamount = Weight * 0.02

       

End Select

3. After you add the code, test your program by pressing F5 key.

4. Enter an Integer in your Textbox and click Calculate

5. Once your program is working, your program looks like the screenshot below.

6. If you see that the screenshot is looks like with yours, Congratulations! You made it.

I hope it help to those beginners who want to know visual basic using Case Select Statement.

What is the meaning of Conductor and Insulator?

Everything in this world harms us if we don’t know how to use or handle it. Electricity is very important and useful one, if we don’t have electricity, we can’t operate computers, big machines, lights and other equipment using electricity. But on the other hand electricity can be a harmful one, if you don’t know how to it, it could be your end. 

So, properly handling and use is recommended to avoid any harmful effects. Electricity can flow to the materials called conductor. 

What is conductor? 

Conductor – is a material with plenty of free electrons, voltage or current can flow.

Example: iron, metal, nickel, silver, gold, aluminum, germanium, tungsten, nicrome, water, copper

Silver 

• is the best conductor.

• very low resistance.

SCAIL – is the descending order of conductivity of a conductor used in an electronic circuit. 

• S – Silver 

• C – Copper 

• A – Aluminum 

• I – Iron 

• L – Lead

Now you know the materials that conduct electricity, so you are now aware about it. If you can see any conductor materials with the presence of electricity don’t touch it without using insulator. 

If we have conductor, we also have insulator. 

I have a simple question, why birds can land to a power-line with 1000 volts presence without electrifying happens? A good question needs a good answer, because bird’s foot has an insulator. 

What is insulator? 

Non Conductor or Insulator – is a material lacks or no free-electrons, voltage or current cannot flow.

Example: rubber, plastic, paper, glass, cork, wood, cloth, porcelain

Glass

• is the best insulator at room temperature 

• it cools

Insulator can be use in troubleshooting deals with electricity.  It is safe to handle electricity when you are using insulator, rubber is a common insulator use in all aspect of dealing with electricity.
