网上有好多使用多线程弹出式等待窗口作为程序中较长时间后台运行提示的，但是做的都不完善，尤其是用 waitThread.Abort() 杀死线程时容易产生异常，进而出错。本程序是比较完善的改进，利用多线程弹出等待窗口，并根据后台程序的运行需要实时发出运行状态信息到等待窗口中，当后台程序运行结束时给弹出窗口线程发出结束信号，让线程自行终止。程序运行环境 vs.net 2010(There are many online multi thread pop-up waiting windows as a reminder for longer time running in the program, but they are not perfect, especially when using waitThread.Abort () to kill threads, it is easy to produce exceptions and make mistakes. This program is improved more perfect, the use of multi-threaded pop-up window to wait, and according to the needs of daemons running real-time running status information issued to wait for the window to signal the end, when the end of the thread popup daemon is running, let the thread to terminate.
