使用VB6编写的“动态托盘图标and防止多次运行”可在系统右下角托盘内实现动态图标，表明程序开始工作，工作结束后可转为静态图标。另一个功能是“防止程序多次运行”，当程序已经运行了，再双击运行程序时会自动切换到程序界面，防止同一个程序多次运行。-Using VB6 prepared " dynamic tray icon and prevent multiple runs"　to the lower right corner in the system tray to achieve dynamic icon, indicating that the program to work, after work can be converted to a static icon. Another function is to " prevent the program from running multiple times,"　when the program is already running, and then double-click to run the program will automatically switch to the program interface to prevent multiple runs of the same program.
