19. Functions

In this tutorial, we cover the Function and how it works. Similar to the sub procedure, a function is also a method which stores code to be executed when called. The difference is, a function returns a value where a sub procedure doesn’t.

Code

Public Class Form1

    Dim labeltext As String = "functions are cool lol"

    Private Function changelabeltext()
        Return labeltext
    End Function

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Label1.Text = changelabeltext()
    End Sub

End Class
