Temperature Converter

With winter around and daily temperature change has become a concern for many people especially those who travel a lot. They are constantly checking out temperature readings everyday However, different parts of the world often use different temperature scales, some of them use Fahrenheit and some use Celsius, so the readings can be confusing. Therefore, it is nice if we have a program that can convert Celsius to Fahrenheit and vice versa. And I have done just that using Visual Basic 6. The code is like this:

Private Sub Command1_Click()
Dim cel, Fah As Single
cel = Val(txtC.Text)
Fah = Val(txtF.Text)

If txtC.Text <> "" And txtF = "" Then
Fah = ((9 / 5) * cel + 32)
txtF.Text = Round(Fah, 1)
Else
cel = (5 / 9) * (Fah - 32)
txtC.Text = Round(cel, 1)
End If

End Sub

Private Sub Command2_Click()
txtC.Text = ""
txtF.Text = ""

End Sub

DataGrid Control

I have included a new lesson related to database management. In the previous chapters, we use textboxes to display data by connecting them to a database via Microsoft ADO data Control 6.0. The textbox is not the only control that can display data from a database, many other controls in Visual Basic can display data. One of the them is the DataGrid control. DataGrid control can be used to display the entire table of a recordset of a database. It allows users to view and edit the data. Please click on Lesson 21(b) to view the latest lesson.

Basic Programming- 30 years ago

Visual Basic have come a long way since the invention of the BASIC language. When I first started learning BASIC back in the late 70's of the last century, personal computers were not popular yet. I remembered I was using the punch card machine to key in the program code, each card represent a program statement. So, for a long program, we have to use many cards. We don't get the output immediately, what we do was to send our cards to the processing center when the technicians would feed the cards into the main frame computer. We would only get our printouts the following day . How slow was it! But we never complain, because we were the lucky ones who have access to the computer those days, many people out there were still ignorant about computer. So, see how lucky you are today, you can have a laptop with the computing power matching or better than the old mainframe, and you get your output instantly!

Financial Crisis Self Help

The financial crisis is getting more and more serious, many financial institutions and banks are going bust and stocks are sinking!
