Hiding a Label without repainting?

Hi everybody.
I have a Label1 visible on Form1. When I make
   Label1.Visible:=false;
the form Form1 is repainted. Is it possible to hide the label without repainting the form Form1? And if possible, how? The problem is relevant when the painting takes much time.
Regards, Alex.

I don't know if this helps, as I guess the painting is automated from the Label.Visible property, but the message

WM_SETREDRAW

and

InvalidateRect( handle, @rect, FALSE ) ;

may help you...( the false stops the whold form repainting, only the bit in the rect...)

hmm,

just an idea,

does the form repaint if you use the form-color as tfont.color of your label instead of hide it.

you could also try
LockWindowUpdate(form1.handle)

Hi Tim.
I tried your idea, more precisely
  "InvalidateRect"
because I didn't know to send a message
wm_SetRedraw. But, as the other ideas didn't help much, I shall try the way you suggested me.

Thanks also to Meikl and Rene.
