操作系统进程内存管理模拟 有关此程序的功能请见程序中的帮助菜单 程序难点1：创建Windows xp中按钮样式 解决方法：使用标签控件与形状控件一起形成此样式 此方法缺点：由于标签没有TAB事件，所以不能使用键盘控制按钮。 此缺点解方法：截取键盘事件，以响应TAB事件（时间有限，没有实现） 程序难点2:实时与分时混合应用 解决方法：置一FOR循环在TIMER中，先判断并响应时实进程，再置另一当循环在TIMER中，无时实时再执行分时进程。 程序难点3：分页式内存管理的调度方式 解决方法：具体方法见程序中的注释。 程序难点4:基于优先级的调度方式 解决方法：使用双重当循环，第一层判断优先级，第二层判断执行进程.-simulating the os process ang memory management on the function of the application please view the help menu of the application

difficult point 1: build a button style for Windows xp.the fault is because the mark has t TAB event,the keyboard can t control the button.Method for resolve :get the keyboard event,and respond the TAB event(for time limit,unsolved)

difficult point2 :real-time and time-sharing mixed

Method to resolve: set a FOR circle in TIMER event,judge and respond the real process,set another circle in TIMER event,do the time-sharing process if no real time one.

difficult point 3:Method for schedule memory management in seperate pages.

Method to resolve: show on the introduce in the application.

difficult point 4 schedule method base on priority,

Method to resolve: use the double circle ,the first can judge the priority the second judge execute process.
