TCHAR and char Manipulation

1. Reset string: memset

char cReaderResponse[300];
memset(cReaderResponse, 0, sizeof(cReaderResponse));


TCHAR tcTmp[300];
memset(tcTmp, 0, sizeof(TCHAR)*300);

2. Copy

strncpy
_tcsncpy

3. Conversion:

MByteToWChar(cReaderResponse, tcTmp,
sizeof(tcTmp)/sizeof(tcTmp[0])); //convert char to TCHAR

//Description:
// This function maps a character string to a wide-character (Unicode) string
//
//Parameters:
// lpcszStr: [in] Pointer to the character string to be converted
// lpwszStr: [out] Pointer to a buffer that receives the translated string.
// dwSize: [in] Size of the buffer
//
//Return Values:
// TRUE: Succeed
// FALSE: Failed
//
//Example:
// MByteToWChar(szA,szW,sizeof(szW)/sizeof(szW[0]));
//---------------------------------------------------------------------------------------
inline BOOL MByteToWChar(LPCSTR lpcszStr, LPWSTR lpwszStr, DWORD dwSize)
{
// Get the required size of the buffer that receives the Unicode
// string.
DWORD dwMinSize;
dwMinSize = MultiByteToWideChar (CP_ACP, 0, lpcszStr, -1, NULL, 0);

if(dwSize < dwMinSize)
{
return FALSE;
}


// Convert headers from ASCII to Unicode.
MultiByteToWideChar (CP_ACP, 0, lpcszStr, -1, lpwszStr, dwMinSize);
return TRUE;
}

//Description:

// dwSize: [in] Size of the buffer

/*
使用方法也很简单,示例如下:
wchar_t wText[10] = {L"函数示例"};
char sText[20]= {0};
WCharToMByte(wText,sText,sizeof(sText)/sizeof(sText[0]));
MByteToWChar(sText,wText,sizeof(wText)/sizeof(wText[0]));
