如何点击单选按扭输出相应的话？
如上。比如我打算点一下单选按扭然后输出一句话。一共4个按扭，比如按下a键输出“你好”，按下b键输出“再见”等等。应该如何弄？

用vb 或 delphi吧
太简单了
1、建个工程
2、建个窗体或表单
3、拉上几个按钮，分别命名
4、双击各个按钮，并生成的函数段中加入代码：
以 vb为例。
private sub command1_click()
textbox1.text = "哈哈，文字输出其不意" ' 输出到文本框
debug.print "哈哈，文字输出" ' 输出到调试栏
? " 哈哈" ' 输出到窗体表单
end sub
5、其它类推。
够明白了吧。
