Postmessage Problem

[Serpentine]

Hi Leute, ich habe folgenden Quelltext geschrieben, er ließ sich auch kompilieren, aber die Main Funktion (Button1Click funktioniert einfach nicht richtig), VK_END und VK_INSERT drückt er wohl aber die Zahlen nicht.

Delphi-Quellcode:

unit Unit2;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls,ShellAPI, Menus, Appevnts, XPMan, ExtCtrls,
  ComCtrls,DateUtils;

const
  WM_TASKABAREVENT = WM_USER+1;

type
  TForm2 = class(TForm)
    PopupMenu1: TPopupMenu;
    disable1: TMenuItem;
    enable1: TMenuItem;
    close1: TMenuItem;
    CheckBox1: TCheckBox;
    Label1: TLabel;
    Label2: TLabel;
    Button1: TButton;
    Edit1: TEdit;
    Edit2: TEdit;
    Edit3: TEdit;
    Label3: TLabel;
    procedure Button1Click(Sender: TObject);
    procedure close1Click(Sender: TObject);
    procedure enable1Click(Sender: TObject);
    procedure disable1Click(Sender: TObject);
    procedure FormDestroy(Sender: TObject);
    procedure FormCreate(Sender: TObject);
  private
    procedure TaskbarEvent(var Msg: TMessage);
    Message WM_TASKABAREVENT;
  public
    procedure WMSysCommand(var Message: TWMSysCommand); message WM_SYSCOMMAND;
  end;

var
  Form2: TForm2;
  wnd:hwnd;

implementation

{$R *.dfm}

procedure delay(msec:longint);
var
  start,stop:longint;
begin
  start := gettickcount;
  repeat
  stop := gettickcount;
  application.processmessages;
  until (stop - start ) >= msec;
end;

procedure TForm2.WMSysCommand(var Message: TWMSysCommand);
begin
  if Message.CmdType and $FFF0 = SC_MINIMIZE then
  begin
    Hide;
  end
  else
    inherited;
end;

procedure TForm2.TaskbarEvent(var Msg: TMessage);
var Point : TPoint;
begin
  case Msg.LParam of
    WM_LBUTTONDBLCLK:
      begin
        form2.show;
      end;
    WM_LBUTTONUP:
      begin
      form2.show;
      end;
    WM_RBUTTONUP:
      begin
        SetForegroundWindow(Handle);
        GetCursorPos(Point);
        PopupMenu1.Popup(Point.x, Point.y);
      end;
  end;
end;



procedure TForm2.FormCreate(Sender: TObject);
var
  NotifyIconData: TNotifyIconData;
begin
  wnd := FindWindow(nil,pchar(edit3.text));
  Fillchar(NotifyIconData,Sizeof(NotifyIconData),0);
  NotifyIconData.cbSize := Sizeof(NotifyIconData);
  NotifyIconData.Wnd    := Handle;
  NotifyIconData.uFlags := NIF_MESSAGE
    or NIF_ICON
    or NIF_TIP;
  NotifyIconData.uCallbackMessage := WM_TASKABAREVENT;
  NotifyIconData.hIcon := Application.Icon.Handle;
  NotifyIconData.szTip := 'AFK Buffer';
  Shell_NotifyIcon(NIM_ADD, @NotifyIconData);
end;


procedure TForm2.FormDestroy(Sender: TObject);
var
  NotifyIconData: TNotifyIconData;
begin
  FillChar(NotifyIconData,Sizeof(NotifyIconData),0);
  NotifyIconData.cbSize := Sizeof(NotifyIconData);
  NotifyIconData.Wnd    := Self.Handle;
  NotifyIconData.uFlags := NIF_MESSAGE
    or NIF_ICON
    or NIF_TIP;
  NotifyIconData.uCallbackMessage := WM_TASKABAREVENT;
  NotifyIconData.hIcon := Application.Icon.Handle;
  NotifyIconData.szTip := 'Punkt';
  Shell_NotifyIcon(NIM_DELETE, @NotifyIconData);
end;

procedure TForm2.disable1Click(Sender: TObject);
begin
checkbox1.checked:=true;
end;

procedure TForm2.enable1Click(Sender: TObject);
begin
checkbox1.checked:=false;
button1.click;
end;

procedure TForm2.close1Click(Sender: TObject);
begin
form2.close;
end;

procedure TForm2.Button1Click(Sender: TObject);
var i,delay0r:integer;
begin
delay0r:= strtoint(edit1.Text);
wnd := FindWindow(nil,pchar(edit3.Text));
if wnd=0 then begin
showmessage('Client not found!');
exit;
end;
application.ProcessMessages;
   PostMessage(wnd, WM_Keydown, VK_END, 0);
   PostMessage(wnd, WM_Keyup, VK_END, 0);
   sleep(50);
   application.ProcessMessages;
   PostMessage(wnd, WM_Keydown, $31, 0);
   PostMessage(wnd, WM_Keyup, $31, 0);
   sleep(delay0r);
   application.ProcessMessages;
   PostMessage(wnd, WM_Keydown, $32, 0);
   PostMessage(wnd, WM_Keyup, $32, 0);
   sleep(delay0r);
   application.ProcessMessages;
   PostMessage(wnd, WM_Keydown, $33, 0);
   PostMessage(wnd, WM_Keyup, $33, 0);
   sleep(delay0r);
   application.ProcessMessages;
   PostMessage(wnd, WM_Keydown, $34, 0);
   PostMessage(wnd, WM_Keyup, $34, 0);
   sleep(delay0r);
   application.ProcessMessages;
   PostMessage(wnd, WM_Keydown, $35, 0);
   PostMessage(wnd, WM_Keyup, $35, 0);
   sleep(50);
   application.ProcessMessages;
   PostMessage(wnd, WM_Keydown, VK_INSERT, 0);
   PostMessage(wnd, WM_Keyup, VK_INSERT, 0);
//repeat
//delay(strtoint(edit2.text)*1000);
//buffen;
//until checkbox1.checked=true;
end;



end.

Ich verstehe einfach nicht warum -.-
