摘要
当两个以上的进程互相要求对方已经占有的资源时,即会出现程序"无响应"现象,此时使用doevents方法,可以实现控制权转移,使操作系统可以处理其它的事件,防止界面停止响应,程序能被控制。
When two or above processes mutually require the resources already occupied by each other, that is, when there is no response, using doevents method can realize control transfer to enable operating system to process other events, so as to prevent the interface from ending response and thus control the program.
