HOW TO CREATE A SIMPLE INTEREST CALCULATOR IN VB6

SIMPLE INTEREST CALCULATOR

Below is the interface of the calculator:

TOOL	CAPTION	NAME
Label1	Enter principal	Label1
Label2	Enter rate	Label2
Label3	Enter time	Label3
Label4		lblResult
Textbox1		txtPrincipal
Textbox2		txtRate
Textbox3		txtTime
Command1	Compute	cmdCompute
Command2	Reset	cmdReset

Below are the code:

Dim principal As Double
Dim rate As Double
Dim time As Double
Dim interest As Double

Private Sub cmdcompute_Click()
principal = Val(txtprincipal.Text)
rate = Val(txtrate.Text) / 100
time = Val(txttime.Text)

interest = (p * r * t) / 100
lblresult.Caption = interest
End Sub

Private Sub cmdreset_Click()
txtprincipal.Text = " "
txtrate.Text = " "
txttime.Text = " "
lblresult.Caption = " "
End Sub

at the first step, we declare our variable using dim and give it a data type double. double has decimal point.

In the second step, we assign our variable to text box and calculate them and also display the result in lblresult (label4)

caption is the name that appear on the form.
