采用VB6.0编程的MD5加密算法。MD5就是采用单向加密的加密算法，对于MD5而言，有两个特性是很重要的，第一是任意两段明文数据，加密以后的密文不能是相同的；第二是任意一段明文数据，经过加密以后，其结果必须永远是不变的。前者的意思是不可能有任意两段明文加密以后得到相同的密文，后者的意思是如果我们加密特定的数据，得到的密文一定是相同的。(Using VB6.0 programming of MD5 encryption algorithm. MD5 is the use of one-way encryption algorithm, for MD5, there are two characteristics is very important, the first is any two plaintext data encrypted ciphertext, later not to be the same second is an arbitrary piece of plaintext encrypted data, then, the results must always be the same. The meaning of the former is unlikely to have any two plaintext after getting the same ciphertext, which means if we encrypt specific data, the encryption must be the same. )

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)

** sBackUpfileName 恢复后的数据库存放目录 ** sDataBaseName 备份的数据名 ** sIsAddBackup 是否追加到备份文件中 **说 明：引用Microsoft ActiveX Data Objects 2.x Library **模 块 名：frestoredatabase_a **描 述：恢复数据库,返回出错信息,正常恢复,返回"" **调 用：frestoredatabase_a "备份文件名","数据库名" **参数说明： ** sDataBasePath 恢复后的数据库存放目录 ** sBackupNumber 是从那个备份号恢复 ** sReplaceExist 指定是否覆盖已经存在的数据 **说 明：引用Microsoft ActiveX Data Objects 2.x Library ">
