calculation in text box

Question

let me know by anyone if i have three text boxes Text Box 1,2 and 3.
The First Text Box pick the gross salary from data base on the bases of selection from the combo box.
i want that the 2nd box calculate salary per day ( Gross Salary / 30). And the 3rd text box calculate salary per hour {(Gross salary/30)/8}.
I have try this code but it is not working.

Public Class Form1



    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Dim grsalry As Integer
        Dim ratprday As Integer
        grsalry = Val(TextBox1.Text)
        ratprday = grsalry / 30

        TextBox2.Text = ratprday

    End Sub
End Class

Thanks

Well if the contents of textbox1 depend on a combobox selection then you'll need to place this code in either the combobox's SelectedIndexChanged handler or textBox1's TextChanged handler if you want the figures to be updated dynamically. Apart from that the basic code looks OK (as long as you're only interested in whole currency units) and I've extended it below to include the 'rate per hour' calculation: Dim grsalry As Integer Dim ratprday As Integer Dim ratprhour As Integer grsalry = Val(TextBox1.Text) ratprday = grsalry / 30 ratprhour = ratprday / 8 TextBox2.Text = ratprday TextBox3.Text = ratprhour

Hi Please try the below code. public partial class Form1 : Form { int salarypM=0; int salaryD=0; public void calculateSalary() { textBox1.Text = 9000; salarypM = Convert.ToInt32(textBox1.Text) / 30; textBox2.Text = salarypM.ToString(); textBox3.Text = (salarypM / 8).ToString(); } public Form1() { InitializeComponent(); calculateSalary(); } } Hope this will help.
