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.此程序不足之处:不能响应键盘事件,没有程序的等待状态,由于LIST控件的先天不足进程列表看上去有点闪烁。当然程序的等待状态可以随机产生但由于没有太多时间专注于此,只好等以后再完善了。希望大家指出不足之处!-the function of this procedure to the procedures set out in the help menu a difficult process : the creation of Windows xp which button style solution : use labeling controls and controls together form the shape of this pattern shortcomings of this approach : no TAB labeling the incident, so we can not use the keyboard to control the button. This solution shortcomings : the interception of the keyboard, in response to the incident TAB (limited time, which did not materialize) procedures difficult 2 : real-time and time-sharing applications mixed solution : Purchase a TIMER FOR cycle, we judge and respond to real-time process, and when the home of another cycle in TIMER, no real-time when the implementation of time-sharing process. Difficulties three procedures : paging memory management so
