说明：  SelfDelete(可以删除自身的VC++源码(巳通过了调试)) 为了实现程序自删除功能，我们可以通过多进程的方法解决这个问题。可执行文件在结束返回前，创建一个运行命令窗口的新进程（在Windows98中为Command进程，在Windows2000/XP中为CMD进程），当然该命令窗口以隐藏方式执行，并通过传递参数执行删除功能。为了避免可执行文件的映像还在内存中就执行删除，需要把当前进程设置为实时优先级，而命令窗口进程设置为很低的IDLE优先级，这样首先可执行文件结束返回，再运行命令窗口的删除命令，就实现了该文件自身的删除功能。
(SelfDelete (you can delete its own VC++ source code (had passed debugging)) In order to achieve the program from the delete function, we can multi-process methods to solve this problem. Return before the end of the executable file, run the command window to create a new process (in Windows98 process for the Command, in Windows2000/XP process for CMD), of course, the command window to hide the manner and to perform delete functions by passing a parameter . In order to avoid the executable file image still in memory on the implementation of delete, you need to set the current process for real-time priority, and the command window to set the process priority to low IDLE, so the end of the first return to the executable file, then run the command window delete command, the file itself to achieve the delete function. )
