简单问题，给分很多啊！！

Question

我想在一个edit中限制输入的键，我是定义一个集合，里面放可输的键，如：backspace的#8，还有一些数字，然后在onkeypress里判断，不在集合里的key：=#0；现在我有些键的键值（哈哈我也不知道是不是叫键值啦，总之#...的），如Tab键是#几，谁能告诉我最好给我一个所有键盘键值的表，我将不胜感激，并给分多多的，谢谢！！！

Answer 1

我不记不住啊，可是我可以教你怎么得到
加一个Edit，在他的keypress事件，写上ShowMessage((int)Key);你看到的就是他的ASCII代码，你也可以随便找本书，比如C语言程序设计等，后面附录都有啊

Answer 2

procedure TForm1.FormKeyUp(Sender: TObject; var Key: Word;
  Shift: TShiftState);
begin
  label1.Caption:=intToStr(key);
end;

Answer 3

每个键对应其Ascii码，如tab1的键值为#41，1的键值为＃49，你可以查ASCII表来验证我的答案

Answer 4

goomoo的方法可以得到键值。。
但我记得大学的C语言书后就有一张表，是ASCII码的，查找很好。
