BN_DBLCLK

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 to button 
 

BN_DBLCLK is the same as the BN_DOUBLECLICKED notification message.

Note  This notification message is provided for compatibility with applications written for 16-bit versions of Windows earlier than version 3.0. Win32-based applications should use the BS_OWNERDRAW button style and the DRAWITEMSTRUCT structure for this task.
