구차니의 잡동사니 모음

Gets a string from the list box of a combo box.

int GetLBText( 

   int nIndex, 

   LPTSTR lpszText  

) const;

void GetLBText( 

   int nIndex, 

   CString& rString  

) const; 

operator LPCTSTR

GetBuffer() 

(LPCTSTR)로 캐스팅하는 것과 거의 구현이 같은 GetString() 이란 메소드도 있습니다. 

CString str = L"английский"; //Russian Language

DWORD dwWritten=0;

WriteFile(pHandle , (void*) str, str.GetLength()*sizeof(TCHAR),&dwWritten , NULL);

char 형식의 좁은 문자 리터럴(예: 'a')

wchar_t 형식의 와이드 문자 리터럴(예: L'a')

char16_t 형식의 와이드 문자 리터럴(예: u'a')

char32_t 형식의 와이드 문자 리터럴(예: U'a') 

TEXT("")과 _T("")의 차이점은

TEXT("")는 WinNT.h에서 #define했고

_T("")는 tchar.h에서 TEXT가 4글자라서 _T이렇게 2글자로 #define했다. 

print repr(a).decode("unicode-escape") 

4.6.5. Tuples

Tuples are immutable sequences, typically used to store collections of heterogeneous data (such as the 2-tuples produced by the enumerate() built-in). Tuples are also used for cases where an immutable sequence of homogeneous data is needed (such as allowing storage in a set or dict instance). 

4.6.4. Lists

Lists are mutable sequences, typically used to store collections of homogeneous items (where the precise degree of similarity will vary by application).
