Button text with shortcutkey letter (ATL)

Hi,
My first post ;-)

I have a custom ATL object that is like a button, I want to add a shortcut to that object, so I want to set a letter with the underscore in the button label,
for example

Push Me

so the u is like ALT+U shortcut (standard windows)

now I set the text on the button with
TextOut ( ... ) ;

But If I put the & in from of the letter I obviously see

P&ush Me

any idea?

Thanx a lot
