Press a button programatically

Hi,
Is there a way to push a button programatically (and for
that matter to emulate any other key/mouse event).
For example when a button is pressed by a mouse/key it
caves in and events get fired.
How do I cause this to happen programatically?
Something like:

MyButton.ClickIt()-and the button caves in

The Windows calculator does it nicely-copy some numbers in
the clipboard and paste them in the calculator and its
buttons get clicked.

Thanks

Hello Herfried

Would Button1.PerformClick() do ?
rather simpler one, though I dont know how to generate mouse events (mousedown/up). For that, winapi would be the thing
to resort to

anyways, got a nice snippet of using winapi from your code (I am from VB background, now in c#) ;-)

It will work, but it won't /visually/ press the button. It will only
call the 'Click' event handlers.
