Here it is:
procedure TForm1.Edit1KeyPress(Sender: TObject; var Key: Char);
begin
  if not (Key in ['0' .. '9', #8, #13]) then
  begin
    //is it ctrl+..
    if HiWord(GetKeyState(VK_CONTROL)) <> 0 then //ctrl down
    begin
      if not (Key in [#3, #22, #24]) then Key := #0; //#3 = CTRL+C, #22 = CTRL+V, #24 = CTRL+X, 
    end
    else
      Key := #0;
  end;
end;

Open in new window

... for comma if number is decimal ... first line should be
if not (Key in ['0' .. '9', #8, #13, #44]) then...

Open in new window


...on torry.net you have lots of numeric edit components already
