DateTimePicker problem im Closeup Event

[toms]

Hallo!

So muesste es funktionieren:

Delphi-Quellcode:

const
  WM_DTPCloseUp = WM_USER + 111; // benutzerspez. Nachricht

type
  TForm1 = class(TForm)
    DateTimePicker1: TDateTimePicker;
    procedure DateTimePicker1CloseUp(Sender: TObject);
  private
    { Private declarations }
    procedure WmAfterShow(var Msg: TMessage); message WM_DTPCloseUp;
  public
    { Public declarations }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.WmAfterShow(var Msg: TMessage);
begin
  // Dein langer Code...
end;

procedure TForm1.DateTimePicker1CloseUp(Sender: TObject);
begin
  PostMessage(Self.Handle, WM_DTPCloseUp, 0, 0);
end;
