Default BMI Calculate


Hi im trying to create vb bmi calculator for my class I did wrote a code for it but it don’t work whenever I debug it and enter a number. The output comes up as 0
This is the code


Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculate.Click
Dim hight, weight, bmi As Integer
hight = Int(txtheight.Text)
weight = Int(txtweight.Text)

bmi = Int(weight) / Int(weight ^ 2)

If weight < 1 And Height < 1 Then
MessageBox.Show("Please enter a positive number", "Input Error")
ElseIf weight = 0 Or Height = 0 Then
MessageBox.Show("Invalid Entry", "Input Error")
End If
lblmassindex.Text = bmi.ToString

Are you sure the line
Code:
bmi = Int(weight) / Int(weight ^ 2)
is correct? You are using weight for both parts.

You might also find that integers are going to round the results and lose precision, a decimal or double might be a more suitable data type to use.

I notice you have put this post in the Asp.Net section but you are also using a Messagebox.Show statement, is this a web or a windows app? If it is a web app then the messagebox will not be displayed on the client's pc.
