procedure TForm1.FormActivate(Sender: TObject);
{設置一個日期型字段的輸入掩碼，
可以放到TField字段定義中。}
begin
  Table1.FieldByName('Birthday').EditMask:=

end;

procedure TForm1.Table1BirthdayGetText(Sender:

begin
  DateFieldGetText(Sender,Text);
end;

procedure TForm1.Table1BirthdaySetText(Sender:
TField; const Text: String);
begin
  if DateFieldSetText(Sender,Text)=False then
    Abort; {轉換不成功,日期非法}
end;
