在Access中如何用自定义的菜单代替Access自带的菜单,现在做一个简单的介绍: 1、打开您做的Access数据库; 2、单击工具栏,选择自定义; 3、在自定义窗口,单击工具栏选项卡; 4、单击新建(N),在弹出窗口中输入工具栏名称(如:系统管理),这个系统管理
在Access中如何用自定义的菜单代替Access自带的菜单,现在做一个简单的介绍:
1、打开您做的Access数据库;
2、单击工具栏,选择“自定义…”;
3、在“自定义”窗口,单击“工具栏”选项卡;
4、单击“新建(N)”,在弹出窗口中输入工具栏名称(如:系统管理),这个“系统管理”这个工具栏会出现[若弹出的是小窗体,只需把小窗体拖放在工具栏上即可]。
5、设置一级菜单:
(1)单击“命令”选项卡;
(2)选择“类别”中的“新菜单”项;
(3)将“命令”中的“新菜单”拖到您刚建立的“系统管理”的工具栏上。
(4)在“系统管理”工具栏上的“新菜单”上按右键,在“命名”中重新输入您想要的名字(如“基础设置”)
重复(1)—(4)可以设置多个一级菜单[或者在“类别”中选择除“新菜单”外相应的项目中“命令”拖入刚建立“系统管理”的工具栏上,这样就在一级菜单上直接功能置于顶级菜单]。
6、设置二级菜单:
(1)在“类别”中选择除“新菜单”外相应的项目;
(2)在右边“命令”中选择相应的项目,拖动到5(4)步骤建立的“基础设置”栏上;
(3)在刚拖动出来的菜单上按右键,在“命名”中重新输入您想要的名字。
依次类推可以设置多个二级菜单[如果有三级菜单,再重复5(1)—(4)步]。
7、单击“工具栏”选项卡,选中“系统管理”;
8、单击右边的“属性”;
9、在打开的“工具栏属性”窗口中,选择“工具栏属性”中的“类型”,设置为“菜单栏”。
10、关闭“工具框属性”窗口,关闭“自定义”窗口。
11、打开菜单栏“工具”-->“启动”。
12、输入“应用程序标题”
13、在“菜单栏”中选择您刚建好“系统管理”,将所有为选中情况的选项全部取消。
14、重启数据库。
这时您看到的就是您自己定义的菜单栏了。

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 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),
