Flashing window when minimized :(

FlashWindow(Application.Handle, True);

If that doesn't work, try this unit (all it does is to import FlashWindowEx from User32.DLL):

unit WinFlash;

interface

uses windows;

type

  TFLASHWINFO = packed record

     cbSize:UINT  ;  //use sizeof function to get size of this structure

     hwnd:HWND  ;    //handle of window to flash (Use application.handle for taskbar button)

     dwFlags:DWORD ; //see constants below

     uCount:UINT  ;  //number of times to flash

     dwTimeout:DWORD ; //time to flash in milliseconds

  end;

  PFLASHWINFO = ^TFLASHWINFO;

const

user32 = 'user32.dll';

//dwFlag settings

FLASHW_STOP = 0; //Stop flashing. The system restores the window to its original state.

FLASHW_CAPTION = 1; //Flash the window caption.

FLASHW_TRAY = 2; //Flash the taskbar button.

FLASHW_ALL = 3; //Flash both the window caption and taskbar button. This is equivalent to setting the FLASHW_CAPTION | FLASHW_TRAY flags.

FLASHW_TIMER = 4; //Flash continuously, until the FLASHW_STOP flag is set.

FLASHW_TIMERNOFG = 12; //Flash continuously until the window comes to the foreground.

function FlashWindowEx(pfwi: PFLASHWINFO): BOOL; stdcall;

implementation

function FlashWindowEx; external user32 name 'FlashWindowEx';

end.
