Answer 1

Try this:

Private Sub TextBox1_KeyDown(sender As System.Object, e As System.Windows.Forms.KeyEventArgs) Handles TextBox1.KeyDown
    If e.KeyCode = Keys.Enter Then
        fun()
    End If
End Sub

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

Private Sub fun()
    MessageBox.Show("Enter key pressed")
End Sub

Answer 2

on Form Misc Properties set the accept button to be Btn1. Equally, you can set a cancel button too to be executed whenever the user presses Esc button.

Code version (through the constructor):

Public Sub New()

    ' This call is required by the designer.
    InitializeComponent()

    ' Add any initialization after the InitializeComponent() call.
    Me.AcceptButton = Btn1
End Sub
