[t.roller]

Mit XE7, WIN8.1 geht folgender Test-Code:

Delphi-Quellcode:

unit Unit1;

interface

uses
  Winapi.Windows, Winapi.Messages, System.SysUtils, System.Variants, System.Classes, Vcl.Graphics, Vcl.Controls, Vcl.Forms, Vcl.Dialogs, Vcl.StdCtrls, Vcl.ExtCtrls;

type
  TForm1 = class(TForm)
    Timer1: TTimer;
    Button1: TButton;
    procedure Timer1Timer(Sender: TObject);
    procedure Button1Click(Sender: TObject);
  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Form1: TForm1;

implementation

{$R *.dfm}

procedure SetCursorToControl(Control: TControl);
var P: TPoint;
begin
  P.X := Control.Width div 2;
  P.Y := Control.Height div 2;
  P := Control.ClientToScreen(P);
  SetCursorPos(P.X, P.Y);
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
  Timer1.Enabled:= TRUE;
  Button1.Enabled:= FALSE;
  Self.WindowState:= wsMinimized;
end;

procedure TForm1.Timer1Timer(Sender: TObject); // interval:= 10000;
begin
  Timer1.Enabled:= FALSE;
  Button1.Enabled:= TRUE;

  Application.BringToFront; //Setzt das zuletzt aktive Fenster auf dem Desktop in den Vordergrund
  Self.WindowState:= wsNormal; // besser als: Application.Restore;

  SetCursorToControl(self);
  mouse_event(MOUSEEVENTF_LEFTDOWN, 50, 50, 0, 0);
  mouse_event(MOUSEEVENTF_LEFTUP, 50, 50, 0, 0);
end;

end.
