ansi和unicode互转工具--免杀版rar_unicode编码_unicode转ascii(2)

1. 不要出现在程序中出现这样的定义 wchar_t fullstop = L"hello";这是奇怪的定义，这个本意是想让字符fullstop等于字符"hello"，但是要知道"hello"只有在unicode编码文件中才能识别为hello这个单词。而vc6，它也是文本处理器，它默认的编码标准是ansi encoding,所以写上这样的一句表达示，会有些奇怪的问题出现，结果肯定是不对的。ansi和unicode互转工具--免杀版rar但是到了EVC 4.0 或者VS2005 中必须要这样写因为这两个开发环境是unicode 编码的。所以处理字符串的时候如CString 类型一定要进行多字节的转换，也就是告诉编译器把unicode(2字节) 转换到ansi(1字节)，经典转换方法有两种如下：

1. CString to ansi char

CString m_address;

char ansiRemoteHost[255];

ZeroMemory(ansiRemoteHost,255);

WideCharToMultiByte(CP_ACP,WC_COMPOSITECHECK,m_address,wcslen(m_address),

ansiRemoteHost,wcslen(m_address),NULL,NULL);

ansi char to CString

CString MyExam::CharToUnicode(BYTE* buf, DWORD bufSize)

{

CString csTemp;

WCHAR *UnicodeStr=new WCHAR[bufSize+1];

DWORD UnicodeSize=MultiByteToWideChar(CP_ACP,0,

(LPCSTR)buf,bufSize+1,UnicodeStr,(DWORD)bufSize+1);

csTemp=UnicodeStr;

delete [] UnicodeStr;

return (csTemp);

}

2. 利用wcstombs and mbstowcs

CString to ansi char

CString m_sendData;

char* sendBuf=new char[m_sendData.GetLength()*2];

wcstombs(sendBuf,m_sendData,m_sendData.GetLength());

ansi char to CString

CString GetLocalIP()

{

HOSTENT* LocalAddress;

char * Buff=new char[256];

TCHAR *wBuff=new TCHAR[256];

memset(Buff,'/0',256);

memset(wBuff,L'/0',256*sizeof(TCHAR));

if(gethostname(Buff,256)==0)

{

mbstowcs(wBuff,Buff,256);

LocalAddress=gethostbyname(Buff);

memset(Buff,L'/0',256);

sprintf(Buff,"%d.%d.%d.%d/0",LocalAddress->h_addr_list[0][0]&0xff,LocalAddress->h_addr_list[0][1]&0x00ff,LocalAddress->h_addr_list[0][2]&0x0000ff,LocalAddress->h_addr_list[0][3]&0x000000ff);

memset(wBuff,L'/0',256*sizeof(TCHAR));

mbstowcs(wBuff,Buff,256);

strReturn=wBuff;

}

delete [] Buff;

delete [] wBuff;

return strReturn;

}

只要掌握这两种转化方法在unicode 的环境中进行编程就不回出现问题了。
