Question : Button Click event fires only once

For winform application: (.net 2.0)
If a user press a button more than once (2, 3, 4 ... times in), I would like the click event to fire once only.
I have found this link already: (but the discussion discarded option 3 and besides I have a lot of buttons to protect against this scenario)

Is there any other way to achieve this? If so how and why is a better solution that the ones on the link shown above.
C# answer required, but VB.net is OK
