Hello
Which version of delphi are you using? if version >= 2007 you can use the set the style property of the progress bar to pbstMarquee, this way you get a nitty effect as shown below. This way you don't need to inform any information about completion.

Hope this helps

If this is not what you want then tell me please

this is supposed to work when button is pressed but its got no event foe a timer and it gives an error on the last bit of code,

procedure TForm1.Button1Click(Sender: TObject);
begin
 Timer1.Enabled := True;end;
procedure TForm1.Timer1Timer(Sender: TObject);
const  cnt: integer = 1;
begin
  ProgressBar1.Position := cnt;
 if cnt = 1 then Label1.Caption := 'Waiting...'  
else
 if cnt = 100 then begin    Label1.Caption := 'Done!';  
  Timer1.Enabled := False;
 end
else    
Label1.Caption := 'Working...';
  Inc(cnt);
end;
end.


error is on inc(cnt);

any ideas how to fix it ?

You can use this component
MarqueeProgressBar v.1.0

http://www.torry.net/vcl/indicat/meters/sgmarqueeprogressbar.zip

This component encapsulates the marquee style above.
Just install and test.

Hope this helps
