Functions and headers

Question

I am currently working on an assignment and it's asking me to use a function with the header Function DayofWeek(dt As Date) As String . This program would be finding the day of the week for a specific date, if someone could explain to me how to implement this function it would be greatly appreciated.

Answer 1

As far as using the function, you'd probably end up doing something like this. I agree with plutonix that you should ideally not really have much in the way of code inside an event handler like code to handle a button click. Rather you should write code in a separate Sub and then invoke the sub from the button click handler - a bit like this maybe

Public Class Form1

    Function DayofWeek(dt As Date) As String
        'your code here ofc :)
    End Function

    Private Sub showWhatDayItIs()
        Dim todaysDay As String
        todaysDay = DayofWeek(Date.Now)
        MessageBox.Show("It's " + todaysDay + " today!")
    End Sub

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        showWhatDayItIs()
    End Sub

End Class

I'm not trying to be condescending, but this article on the Code Project is a pretty good starter for Object Oriented Programming :-

Answer 2

You could do this:

Public Function DayofWeek(dt As Date) As String
    Return dt.DayOfWeek.ToString()
End Function
