Compile error: expected end of statement occurs when 'Handles' keyword is used

I'm sorry for asking what is probably a noob question, but I've just started learning VBA and don't understand why this happens. I'm trying to make a command button in a user form that initiates a sub routine when it is pressed, but when I start trying to code this subroutine using:

Private Sub CommandButton1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CommandButton1.Click

End Sub

I get the error message; 'Compile error: expected end of statement occurs' with the word 'Handles' highlighted.

Any help is much appreciated,
