Да, как обычно, перехватываем WM_SYSCOMMAND.
type TForm1 = class(TForm) private { Private declarations } procedure WMSysCommand(var Msg: TWMSysCommand); message WM_SYSCOMMAND; public { Public declarations } end; var Form1: TForm1; implementation {$R *.DFM} procedure TForm1.WMSysCommand; begin if (Msg.CmdType = SC_MINIMIZE) or (Msg.CmdType = SC_MAXIMIZE) then MessageBeep(0) else inherited; end; |
