今天项目中60秒倒计时模块需要用到GetTickCount(),这个函数,在此做下整理和总结. 1.定义 For Release configurations, this function returns the number of milliseconds since the device booted, excluding any time that the system was suspended. GetTickCount starts at 0 on boot and then cou
最近做了个项目用到了数据库登录,A登陆后把登录状态保,个人信息存在Session里,但是奇怪的是,只要有一个用户登录后在其他电脑上打开上述页面,则也显示A登录状态,注销也不管用了.以前还号的.求大神啊. 以下是BasePage的代码,其他需要验证登录的页面继承该类 public class BasePage : System.Web.UI.Page { //protected User_Info Uinfo = new User_Info(); //登录的判断 public static Use
GetTickCount(),这个函数,在此做下整理和总结.1.定义For Release configurations, this function returns the number of milliseconds since the device booted, excluding any time that the system was suspended. GetTickCount starts at 0 on boot and then counts up from there.在
函数的计算结果类型是double,单位是秒. 要使用更精确的计时,就需要使用getCPUTickCount(),不过现代计算机CPU的频率会随着负载而变化所以没大有必要使用该函数,可以参看函数的介绍[Also, since a modern CPU varies the CPU frequency depending on the load, the number of CPU clocks spent in some code cannot be directly converted to t
