匈牙利命名法规则.doc

匈牙利命名法规则一般情况下，变量的取名方式为： + + 。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LmClass LmObject表示类型本身不与范围前缀结合使用IInterface 接口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LmSketPoint表示草图点的类定义，而它的两个实例 _StartPoint,_EndPoint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.凡围前缀:前缀类型例子备注g_全局作用域g_Serversm_成员变量m_pDoc, l_局部作用域l_strName少用注：编程时尽量少用全程变量，对于全程变量还应在类型前缀后加上如下关键字：特征模块 ： Fea草图模块 ： Sket装配模块 ： Asm工程图模块： Lay曲面模块 ： Surf界面模块 ： Ui常用的一般数据类型的前缀前缀类型内存规格描述例子chchar8-bit characterchGradechTCHAR16-bit character if _UNICODE is definedchNamebBOOLBoolean valuebEnablednintInteger (size dependent on operating system)nLengthnUINTUnsigned value (size dependent on operating system)nLengthwWORD16-bit unsigned valuewPoslLONG32-bit signed integerlOffsetdwDWORD32-bit unsigned integerdwRangep*Ambient memory model pointerpDoclpFAR*Far pointerlpDoclpszLPSTR32-bit pointer to character stringlpszNamelpszLPCSTR32-bit pointer to constant character stringlpszNamelpszLPCTSTR32-bit pointer to constant character string if _UNICODE is definedlpszNamehhandleHandle to Windows objecthWndlpfn(*fn)()callbackFar pointer to CALLBACK functionlpfnAbort常用Windows对象名称缩写Windows 对象例子变量MFC类例子对象HWNDhWnd;CWnd*pWnd;HDLGhDlg;CDialog*pDlg;HDChDC;CDC*pDC;HGDIOBJhGdiObj;CGdiObject*pGdiObj;HPENhPen;CPen*pPen; HBRUSHhBrush;CBrush*pBrush; HFONThFont;CFont*pFont; HBITMAPhBitmap;CBitmap*pBitmap; HPALETTEhPalette;CPalette*pPalette; HRGNhRgn;CRgn*pRgn; HMENUhMenu;CMenu*pMenu; HWNDhCtl;CStatic*pStatic; HWNDhCtl;CButton*pBtn;HWNDhCtl;CEdit*pEdit; HWNDhCtl;CListBox*pListBox;HWNDhCtl;CComboBox*pComboBox;Visual C+常用宏定义命名列表前缀符号类型符号例子范围IDR_标识多个资源共享的类型IDR_MAINFRAME1 to 0x6FFFIDD_对话框资源(Dialog)IDD_SPELL_CHECK1 to 0x6FFFIDB_位图资源(Bitmap)IDB_COMPANY_LOGO1 to 0x6FFFIDC_光标资源(Cursor)IDC_PENCIL1 to 0x6FFFIDI_图标资源(Icon)IDI_NOTEPAD1 to 0x6FFFID_IDM_工具栏或菜单栏的命令项ID_TOOLS_SPELLING0x8000 to 0xDFFFHID_命令上下文帮助(Command Help context)HID_TOOLS_SPELLING0x18000 to 0x1DFFFIDP_消息框提示文字资源IDP_INVALID_PARTNO8 to 0xDFFFHIDP_消息框上下文帮助(Message-box Help context)HIDP_INVALID_PARTNO0x30008 to 0x3DFFFIDS_字符串资源(String)IDS_COPYRIGHT1 to 0x7FFFIDC_对话框内的控制资源(Control)IDC_RECALC8 to 0xDFFFVISUAL C+ 下的数据类型类型含义ATOMAtom.
