Display an "&" in a button

How do you display an "&" symbol in a button?

&&

Label1.Caption = "&&foo"

Label1.Caption = "&&foo"

Thanks... but whats "foo"

and whats the "therory" behind the "&&" to make it work?

"foo" is a string of three letters. ;)

"&&" is an escape sequence. One ampersand makes an underlined character and makes that character an access key. Two ampersands displays a single ampersand and no underline nor access key is created. For the full description, read about the caption property in the MSDN.

so would three ampersands make an underlined ampersand?

No, the "&" can't be used as an access key. If you put in "&&&File" You end up with &File.
