匈牙利命名规则(转载)

1.匈牙利命名规则

变动   前缀     类型

       a       Array                                                  

        bl     Boolean                        //b       Boolean                                                 

        b       Byte                            //by      Byte                                                        

        c       Char                           //有符号型字符                    

        cb      Char Byte                  //无符号型字符（没多大用处）      

        cr      ColorRef                     //颜色参考值                      

        cx,cy   Length of x,y (ShortInt)        //坐标差（长度）                  

        dw      Double Word                                                    

        fn      Function                                                         

        h       Handle                                                          

        i       Integer                                                           

        m_      Member of a class                                                 

        n       Short Integer                                                     

        np      Near Pointer                                                      

        p       Pointer                          lp      Long Pointer              

×(str) s       String                                                           

        sz      String with Zero End              //以字符'/0'结尾的字符串          

        tm      Text                                    //文本内容                        

        w       Word                                                          

        x,y     Coordinate                          //坐标                            

  2.系统命名约定

2.1 VC中变量命名时的前缀约定

Array       a...                        //例：CStringArray saText                                       

BOOL     b...

UINT       n...

int          i...

short       n...

long        l...

WORD     w...

DWORD     dw...

float         f...

char         c...

char*        psz...

TCHAR*     psz...

LPCTSTR    lpsz...

CString      str...

COLORREF cr...

LPLOGPALETTE lp...  (包括LP开头的类型都是这样)

POINT      pt...

CPoint      pt...

HANDLE   h...

HGLOBAL  h...       (包括H开头的类型都是这样)

说明：

     1.如果是指向上述类型的指针，就在上面规范前加 "p" ;

     2.如果是指向上述类型的双重指针，就在上面规范前加 "pp" ;

     3.如果是类成员变量，则在上面规范前加 "m_";

     4.全局变量,则在上面规范前加 "g_";

     5.在类型前加了"const",命名约定不变;  //最好在其中加个c,比如psz --> pcsz.

 

2.2 VC中变量命名时的后缀约定

1.MFC类

CWnd*  p...Wnd  省去的地方一般为该类的用途 (如果是某一个类的成员，则还应该在前加 "m_")又如：CView* p...View

 

2.3 局部变量应尽量易懂简洁，使用常见的变量，如Num,nCount,i,j,k,n,len,pos, offset,nReadNum,index,nRet,ret, string,filename临时变量，如ltmp,ftmp,tmpStr,tempStr 。。。

2.4 函数命名也应该见名知意。如CalcAllDataStyle(),ReadDocDataFromTime(),GetIndexInfo()
常见的函数Init_, Open_, Create_, Get_, Set_, Read_, Load_, Write_, Start_, Stop_, Check_, Test_, Fill_, Process_, Sort_, Do_, Select_, Is_, Exist_,_Ex…

2.5 禁止使用汉语拼音来命名；

2.6在代码中尽量不用具体的大小数值，定义成宏，便于以后维护,如：

#define MAX_DOWNLOADNUM 20
struct DownInfo m_DownInfo[MAX_DOWNLOADNUM];

2.7 VC中一些控件的缩写：

ComboBox  cmb

Edit        edt

Dialog      dlg

ListBox     lst

Picture      pic

Animate     ani
