Hi,
When you main form is minimized the Application objects OnMinimize is called. Respectively when you press the application icon on the taskbar Application's OnRestore event is triggered. Seek TApplication from Delphi Help and find OnMinimize event example.

Inter is a hundered percent right, here is a code snippit to show a message when the form is minimized and maximized...

first add this to the type section (looks like this)
type
  TForm1 = class(TForm)
    procedure FormCreate(Sender: TObject);
    procedure AppMinMessage(Sender: TObject);//here is first
    procedure AppMaxMessage(Sender: TObject);//here is secound

then pass the procedures like so...

procedure TForm1.FormCreate(Sender: TObject);
begin
 Application.OnMinimize  := AppMinMessage;
  Application.OnRestore := AppMaxMessage
end;

procedure TForm1.AppMinMessage(Sender: TObject);
begin
 ShowMessage('Minimize');
end;

procedure TForm1.AppMaxMessage(Sender: TObject);
begin
 ShowMessage('Maximize');
end;

Hope this helps...

Good cutting and pasting there, how about using your own code to answer this question or don't answer it at all...(Orginal, but un-called for...)

michaue, wake up!  I think BoRiS added a comment instead of an answer because he didn't want to step on Inter's toes!  (Unlike some people...)

OK OK, but still then this question just lies there and gets historic or should I say pre-historic.
