BN_DBLCLK  1PHDM3W 

The BN_DBLCLK notification message is sent when the user double-clicks a button that has the BS_OWNERDRAW or BS_RADIOBUTTON style. The parent window of the button receives this notification message through a WM_COMMAND message.

BN_DBLCLK

idButton = (int) LOWORD(wParam);    // identifier of button

hwndButton = (HWND) lParam;         // handle of button

BN_DBLCLK is the same as the BN_DOUBLECLICKED notification message.

This notification is provided for compatibility with applications written for versions of Windows earlier than version 3.0. New applications should use the BS_OWNERDRAW button style and the DRAWITEMSTRUCT structure for this task.
