Sounds like you are ignorning my earlier advice and setting "Visible"
to false. Don't. Leave "Visible" set to true and put the component
underneath another one (Right click, Control.., Send to back). It'll
still be visible as far as Windows is concerned but the user won't be
able to see it because it's covered up.

You're right that most are pretty bad and it's another pet hate of
mine. A progress bar should give the user an idea of how long before
they can give the next command. Most of the time this is the point at
which the process stops but it doesn't have to be. Just so long as it
gives me a good idea when to put my book down and reach for the
keyboard :)

Yeah but then we're back to losing [Space] activation on a button plus
users can see the focus border around the button and might wonder
what's going on.

/That's/ why I've set the form's Keypreview to true (knew there was a
reason <g>). By setting that it gets first dibs on keypresses..but only
grabs them when the TEdit has the focus:

void __fastcall TfrmViewer::FormKeyDown(TObject *Sender, WORD &Key,
      TShiftState Shift)
{
  if( MyVariables.MyViewerFocusedF )
  {
    bool updateF=ViewerSupport_FormKeyDown( Key, Shift,
                                            MyVariables,
                                            sbBlockView );

    if( updateF )
    {
      setNewBlockPosition( MyVariables.MyCurrentBlockNumber );

      Key='\0';
    }
  }
}

If the viewer doesn't have the focus the function does nothing and the
keypress gets handed on to someone else to deal with.

Ah..it's all coming back to me now :)

Or Windows networking, or RS232 connections :)
