如何在程序中友好提示错误

昨天装配脑袋在交流会上讲了2005的新功能可以友好定义错误提示，我们也可以在vs2002/3中实现(所有代码参考sharpdevelop)http://www.icsharpcode.net

1.定义一个静态函数

static void ShowErrorBox(object sender, ThreadExceptionEventArgs eargs)
        {
            DialogResult result = new ExceptionBox(eargs.Exception).ShowDialog();

            switch (result) 
            {
                case DialogResult.Ignore:
                    break;
                case DialogResult.Abort:
                    Application.Exit();
                    break;
                case DialogResult.Yes:
                    break;
            }
        }

2.程序启动之前：

Application.ThreadException += new ThreadExceptionEventHandler(ShowErrorBox);

3.最后是ExceptionBox的定义
