Byte conversion, digital conversion string

Character and Numeric Conversion

TCHAR buff[100];

// 2. Numeric characters turn

// sprintf(); wsprintf() ,_stprintf()

_stprintf_s(buff,_T("%d"), number);

// 3. String integer conversion

// sscanf_s(); swscanf_s(), _stscanf_s();

int number2 = 0;

_stscanf_s(buff, _T("%d"), &number2);

MessageBox(NULL, buff, 0, 0);

return 0;

}

Multi-byte wide byte conversion

// wide character to a multi-character (Unicode -> ASCII) 

#define WCHAR_TO_CHAR(lpW_Char, lpChar) \

WideCharToMultiByte(CP_ACP, NULL, lpW_Char, -1, \

lpChar, _countof(lpChar), NULL, FALSE);

// multi-character converted to wide characters (ASCII -> Unicode) 

#define CHAR_TO_WCHAR(lpChar, lpW_Char) \

MultiByteToWideChar(CP_ACP, NULL, lpChar, -1, \

lpW_Char, _countof(lpW_Char));

// 4. Multibyte wide and byte conversion

char * szChar = "hello 15pb";

wchar_t szWchar[100];

char szBuff[100];

// multi-byte wide transfer byte

CHAR_TO_WCHAR(szChar, szWchar);

MessageBoxW(NULL, szWchar, NULL, NULL);

// wide byte conversion multibyte

WCHAR_TO_CHAR(szWchar, szBuff);

MessageBoxA(NULL, szBuff, NULL, NULL);
