You can use API function:

SystemParametersInfo(SPI_SETSCREENSAVEACTIVE, FALSE, 0, 0)

You can send any mouse message (WM_MBUTTONDOWN) to screensaver window. It handle you can find by using WindowFromPoint() function at any point of the screen.

unit Unit1;

 interface

 uses
   Windows, Messages, SysUtils, Classes,
   Graphics, Controls, Forms, Dialogs;

 type
   TForm1 = class(TForm)
   private
     procedure WMSysCommand(var Msg : TWMSysCommand);
               message WM_SYSCOMMAND;
   public
     { Public declarations }
   end;

 var
   Form1: TForm1;

 implementation

 {$R *.DFM}

 procedure TForm1.WMSysCommand(var Msg : TWMSysCommand);
 begin
   //trap the message and set its result to -1
   if (Msg.CmdType = SC_SCREENSAVE) then
 begin
    // Msg.Result := -1
    Close; //Close Down Program!
end
   else
     inherited;
 end;

 end.

This will close your delphi program down when the screen saver activates... exactly how you asked.... :)
