Public Class Form1


    Private Sub KryptonButton2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles KryptonButton2.Click

Dim ftn as integer
dim stn as integer
ftn = TextBox1.Text
stn= val(ftn)
stn = TextBox2.Text
  End Sub
End Class

Is the intention to add all the digits of the number whatever its size? So 23456 would be 16, for example? In that case you need to split the text into single digits.

Dim i As Integer = 0
        For Each digit In TextBox1.Text 'takes advantage of nature of string as char array
            i += Val(digit)
        Next
        TextBox2.Text = i.ToString

And what would you do if the user entered 124, do you splut to 12+4 or 1+24. Think past smaller size values.

try this:

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim value As Integer
        If Integer.TryParse(TextBox1.Text, value) Then
            Dim numbers() As Integer = Array.ConvertAll(TextBox1.Text.ToArray, Function(c) CInt(c.ToString))
            Label1.Text = String.Join("+", Array.ConvertAll(numbers, Function(x) x.ToString)) & "=" & numbers.Sum.ToString
        Else
            Label1.Text = ""
        End If
    End Sub

End Class

see if user inputs values like 99 then 9+9=18 and 123 then 1+2+3=6 like this anything enters it is converted pls tel the code now

[charuwaka]

Not like that when i enter 16 then it should come as 1+6=7 and 256 then 2+5+6=13 like that out put should come
