Am trying to develop a application that either Sum or gives Product of numbers 1 to 20. It outputs results into lstoutput. Using 2 radio buttons. 1 for SUM, 1 for PRODUCT. in a textbox you list a number 1 to 20, click calculate. from there, depending on which radio button selected, it will give results in a lstoutput listbox below. Question selecting a setting controls for radio buttons, is there a selection in property window that i sent for each radio button so that i do not need to add code in the form for either SUM or PRODUCT?

This is my first time using VB Forums. please be patient if i post something incorrect. hints and guidance are always welcome

Are you asking if there is a shortcut way to do this calculation by using some sort of built-in properties of a radio button? If so, the answer is no.

Presumably, this homework assignment has been assigned in conjunction with learning about using loops, so that's where you'll want to start.

Good luck.

Even if there was, you would almost certainly not get any marks for that because the whole point of the assignment is to write that code. Beginner assignments often expect you to do things in ways that you never would in a real application because they are trying to teach you something specific about the fundamentals of programming. In this case, you could use Enumerable.Range().Sum() to calculate the sum but that's not the point of the assignment so you'd justifiably get no marks for doing so.

Also, the title you wrote has not connection at all to the question you asked. Try to summarise the topic of the question in the title.

I'd recommend adding a class for your calculations...

Public Class calc

    Public Shared Function getSum(n as integer) as Integer
        Dim result as integer = 0
        ' put your loop here

        Return result
   End Function

    Public Shared Function getProduct(n as integer) as Integer
        Dim result as integer = 0
        ' put your loop here

        Return result
   End Function

End Class

Then in your Button_Click

Public Sub Button1_Click(sender as Object, e as EventArgs) Handles Button1.Click
    yourLabel.Text = if(RadioButton1.Checked, "The sum of the numbers 1 to " & number & " is " & calc.getSum(number), _
                                                                   "The product of the numbers 1 to " & number & " is " & calc.getProduct(number))
End Sub
