[bitsetter]

Versuche es mal hiermit:

Delphi-Quellcode:

    procedure FormCreate(Sender: TObject);
  private
    { Private declarations }
    procedure MeineAppOnMessage(var Msg: TMsg; var Handled: boolean);
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.MeineAppOnMessage(var Msg: TMsg; var Handled: boolean);
begin
  case Msg.Message of
    WM_MouseMove:
      begin
      //mach was!
      beep;
      end;
    WM_LBUTTONUP:
      begin
      //
      end;
  end;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
  application.OnMessage:= MeineAppOnMessage;
end;

end.

Das onCreate Ereignis der Form nicht vergessen!
