Q:
I want to hide the vertical scrollbar on a dbgrid when the record count
exceed a number. How can I do that?

A:
Make a descendent of the TDBGrid class. Add a handler for the
WM_NCCALCSIZE message.

*)

type
  
TNoScrollDBGrid = class(TDBGrid)
  private
    procedure 
WMNCCalcSize(var Msg: TMessage);
      message WM_NCCALCSIZE;
  end;

procedure TNoScrollDBGrid.WMNCCalcSize(var Msg: TMessage);
const
  
Scrollstyles = WS_VSCROLL or WS_HSCROLL;
var
  
Style: Integer;
begin
  
Style := GetWindowLong(Handle, GWL_STYLE);
  if (Style and Scrollstyles) <> 0 then
    
SetWindowLong(Handle, GWL_STYLE, Style and not Scrollstyles);
  inherited;
end;

//This removes both scrollbars. If you want to remove only the vertical one
//change the scrollstyles constant accordingly.
