Celsius To Fahrenheit in VB.NET

A simple program that I wrote using Visual Basic .NET to ask the user to give temperature value in Celsius and then our program will convert the given Celsius temperature into Fahrenheit equivalent.

Program Listing

Public Class Form1

Dim celsius As Integer

Dim fahrenheit As Double

Dim solve_fahrenhiet As Double

Private Sub Button4_Click(sender As Object, e As EventArgs) Handles Button4.Click

MsgBox("This program written By Jake Rodriguez Pomperada", vbInformation, "About This Program")

End Sub

Private Sub Button3_Click(sender As Object, e As EventArgs) Handles Button3.Click

End

End Sub

Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click

TxtCelsius.Text = ""

TxtFahrenheit.Text = ""

TxtCelsius.Focus()

End Sub

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

celsius = Val(TxtCelsius.Text)

fahrenheit = Val(TxtFahrenheit.Text)

solve_fahrenhiet = (9 / 5) * (celsius + 32)

TxtFahrenheit.Text = solve_fahrenhiet

End Sub
