推荐使用的数据访问对象 (DAO) 的前缀

用下列前缀来指示数据访问对象。

数据库对象	前缀	例子

一些例子：

Dim dbBiblio As Database
Dim recPubsInNY As Recordset, strSQLStmt As String
Const DB_READONLY = 4            ' 设置常量。
'打开数据库。
Set dbBiblio = OpenDatabase("BIBLIO.MDB")
' 为SQL 语句设置文本。
strSQLStmt = "SELECT * FROM Publishers WHERE _
   State = 'NY'"
' 创建新的记录集对象。
Set recPubsInNY = db.OpenRecordset(strSQLStmt, _
   dbReadOnly)

推荐使用的菜单前缀

应用程序频繁使用许多菜单控件，对于这些控件具备一组唯一的命名约定很实用。除了最前面 "mnu" 标记以外，菜单控件的前缀应该被扩展：对每一级嵌套增加一个附加前缀，将最终的菜单的标题放在名称字符串的最后。下表列出了一些例子。

菜单标题序列	菜单处理器名称
File Open	mnuFileOpen
File Send Email	mnuFileSendEmail
File Send Fax	mnuFileSendFax
Format Character	mnuFormatCharacter
Help Contents	mnuHelpContents

当使用这种命名约定时，一个特定的菜单组的所有成员一个接一个地列在 Visual Basic 的“属性”窗口中。而且，菜单控件的名字清楚地表示出它们所属的菜单项。
