VB6.0禁止修改系统时间的源代码，Windows系统时间有时是自动更新的，如果不选择自动更新，可以手动去修改它，但目前有一些流行的恶意程序为了自己软件方便会强制修改系统时间，本程序可禁止用户或程序修改系统时间，虽然主窗口打开后什么也没，但此时你双击右下角的Windows系统时间，弹出面板内修改时间的话，你会发现修改过的时间会自动恢复，无法修改。本程序的用意并不是在于让用户就这么运行着要程序，而是让VB编程者可从代码中提取出有用的代码，作为一个模块来用，实现禁止修改Windows系统时间的功能。(VB6.0 prohibit changes to the system s source code, Windows system automatically updates the time and sometimes, if you do not choose to automatically update, you can manually to modify it, but there are some prevalent malicious software programs for their own convenience will force changes to the system, this program can prevent users from modifying the system or program time, although the main window opens after nothing but time to time you double-click on the Windows system the lower right corner to bring up the panel s modification time, you will find the modified time will be automatically restored, can not be modified. This program is not intended that allows users to program running on so, but let VB programmers can be extracted from the code of useful code as a module to use, modify the Windows system time to achieve a ban functio)
