WM_Hotkey und WndProc - Error : Ungültiges Fensterhandle !?!

[Assun]

Hi !

Edit //

Also der error is nur weg und es lässt sich kompilieren...

jedoch kommt nun beim start des Programmes der error "ungültiges Fensterhandle" und das Prog killt sich selbst wieder

hier mein kompletter Code :

Delphi-Quellcode:

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, XPMan, ComCtrls, jpeg, ExtCtrls, Menus, ButtonComps;

type
  TForm1 = class(TForm)
    Image1: TImage;
    ImageButton1: TImageButton;
    ImageButton2: TImageButton;
    ImageButton3: TImageButton;
    Bezeichnung: TEdit;
    Aktion: TEdit;
    Aktion2: TEdit;
    Button1: TButton;
    procedure Button1Click(Sender: TObject);
    procedure ImageButton2Click(Sender: TObject);
    procedure ImageButton1Click(Sender: TObject);
    procedure Image1MouseDown(Sender: TObject; Button: TMouseButton;
      Shift: TShiftState; X, Y: Integer);
    procedure FormDestroy(Sender: TObject);
    procedure FormCreate(Sender: TObject);
  private

  public
    procedure WMHotKey(var msg: TMessage); message WM_HOTKEY;
    procedure WndProc(var mymsg: TMessage); override;
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

const
  MY_MENU_ID = 999;

procedure TForm1.WndProc(var mymsg: TMessage);
var
  hMenu        : THandle;
begin
  // Unnötige Systemmenü-Punkte entfernen
  hMenu := GetSystemMenu(Handle, False);
  if hMenu <> 0 then
  begin
    if not DeleteMenu(hMenu, 6, MF_BYPOSITION) then
      ShowMessage(SysErrorMessage(GetLastError));
    DrawMenuBar(hMenu);
  end;
end;


// Auf die HotKeys reagieren
procedure TForm1.WMHotKey(var msg: TMessage);
begin
  Case msg.WParam of
    01: ShowMessage('F1');
    02: ShowMessage('F2');
  end;
end;

procedure TForm1.FormCreate(Sender: TObject);
begin
// HotKeys registrieren
RegisterHotKey(Handle,01,0,vk_F1);
RegisterHotKey(Handle,02,0,vk_F2);
end;

procedure TForm1.FormDestroy(Sender: TObject);
begin
// HotKeys wieder freigeben
UnregisterHotKey(Handle,01);
UnregisterHotKey(Handle,02);
end;




procedure TForm1.Image1MouseDown(Sender: TObject; Button: TMouseButton;
  Shift: TShiftState; X, Y: Integer);
begin
ReleaseCapture;
Form1.Perform(WM_SYSCOMMAND, $F012, 0);
end;

procedure TForm1.ImageButton1Click(Sender: TObject);
begin
Application.Terminate;
end;

procedure TForm1.ImageButton2Click(Sender: TObject);
begin
Application.Minimize;
end;


end.
