   1、如何修改SQL Server 2000身份验证模式和系统管理员?

  分析:由于千方百剂软件,在数据库安全方面采用了最安全的方式“混合模式”,它主要应用于网络主要是Novell网络或者对等网,,使用SPX/IP协议和SQL Server验证模式。

  优点如下:

  创建了Windows NT/2000之上的另外一个安全层次。

  支持更大范围的用户,例如非Windows NT客户、Novell网络等。

  一个应用程序可以使用单个的SQL Server登录和口令。

  下面以操作系统Windows 2000上的SQL Server 2000为例,对误将身份验证模式选择为“windows身份验证模式”的数据库进行修改,操作步骤为:

  1. 打开企业管理器,依次展开服务器组,用右键单击软件使用的服务器。

  2. 在弹出的快捷菜单,执行“属性”命令,出现“SQL Server属性”对话框。如图3所示。单击“安全性”标签,在“安全性”选项框中,将“仅Windows”改为“SQL Server和Windows”身份验证。

  3. 设置完成后,单击“确定”按钮,系统提示重新启动服务器。

  4. 单击“是”按钮,完成对身份验证模式的修改。

  说明:在 Windows XP操作系统与Windows 2000操作系统下修改SQL Server 2000身份验证模式相同,但在Windows 98操作系统下,却不能通过以上方法对身份验证模式进行修改。因为在Windows 98操作系统下,安装SQL Server 2000时,系统只支持“混合模式”身份验证模式。

  2、如何修改SQL Server 2000系统管理员Sa的登录密码?

  分析:SQL Server 2000系统管理员Sa的登录密码,一般在安装SQL Server 2000时就已经设置。在数据库管理系统中,用检查口令等手段来检查用户身份,合法的用户才能进入数据库系统。千方百剂系列需要通过验证Sa登录密码才能创建、删除账套,这样Sa的登录密码在此就显得尤为重要。

  操作步骤如下:

  1. 打开企业管理器,依次展开服务器组,然后展开服务器。

  2. 打开“安全性”文件夹,单击“登录”,然后用右键单击“Sa”,执行“属性”命令。

  3. 弹出“SQL Server登录属性”对话框,如图4所示。在“SQL Server身份验证”密码栏,输入最新密码。

  4. 单击“确定”按钮,弹出“确认密码”对话框,再输一遍登录密码。

  5. 单击“确定”按钮,完成对Sa登录密码的修改。

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
