匈牙利命名法则

一般情况下，变量的取名方式为：

+ + vqualifier> 范围前缀_，类型前缀_,限定词

特殊的类型命名，前缀表示：

类、接口 前缀 类型 例子 备注 表示类型本身 不与范围前缀结合使用 Lm I Class In terface 接口 LmObject IUnknown 注：类名前缀改为Lm，对于非全局的类最好有语义表示其所属模块。类的 实例命名与类名大致相同，只是类名语义表示类的通用含义，而类名表示此实例 的具体语义。如类名LmSketPoi nt 表示草图点的类定义，而它的两个实例 _StartPoi nt,_E ndPoi nt 分别代表起点和终点的语义。类的实例命名带上前缀 。

特殊约定：

a. MouseTool的派生类的前缀为_Mt.

b .对话框类的前缀为CDlg. c.橡皮条类的前缀为_Rb. 范围前缀: 前缀 类型 全局作用域 成员变量 例子 备注「 g m l

g Servers m pDoc, 少用: 局部作用域 l strName 注：编程时尽量少用全局变量，对于全局变量还应在类型前缀后加上如下关
