Buttons

I am sure that on many applications you have seen buttons displaying "Previous", "Next" and "Finish" on their forms. That is exactly what buttons are for. To add a button to your form simply double click on the button control in your toolbox, usually located on the left side of your window. It looks something like this.

Figure 3: Toolbox

Now if you double click on the button control it will create a button on your form and name it Button 1. To open the properties dialog for the button control simply click once on the desired button on your form. In the properties dialog you can then change the text, name and other properties. In forms load event handler you can also specify your button as the forms accept/cancel button.
AcceptButton: The button recognizes a click when ever the user presses "Enter".
CancelButton: The button recognizes a click when ever the user presses "Escape".
Example:

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.AcceptButton = Button1
End Sub

Now to give our button a function. Lets use our button to change the Form.text from "Form1" to "My New Form". First double click on your desired button on your form to go to the click event handling for the chosen button. You should see something like this:

Public Class Form1

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Me.AcceptButton = Button1
End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

End Sub
End Class

Between the Private Sub Button1_Click and the End Sub enter me.text = "My New Form". The code should now look like this:

Press the "Start debugging" button and test your application.
