BN_DBLCLK notification code

Sent when the user double-clicks a button. This notification code is sent automatically for BS_USERBUTTON, BS_RADIOBUTTON, and BS_OWNERDRAW buttons. Other button types send BN_DBLCLK only if they have the BS_NOTIFY style.

The parent window of the button receives this notification code through the WM_COMMAND message.
