截屏、闪屏(Timer)、输入窗口--DFL for D2.053

这个小练习用D2.053+DFL完成了以下功能：
1.截屏（Chris的例子）；
2.用截屏做闪屏,Timer（用Chris的例子）；
3.数据库登陆窗口（数据库连接部分暂没做）；
4.输入窗口模块module inputbox,从窗口输入中获得一个字符串和一个整数可以这样：

string input=inputBox.getString("用户自定义提示","用户自定义默认值");
int anInt=inputBox.getInt("","");

省略参数则使用默认参数值。
对类型转换未进行错误检查。
5.菜单的创建(Chris的例子）
6.Chris的MemoryGraphic例子收录（只是试了一下）；
