VC从Multi Byte字符串转换为UNICODE字符串的函数

wchar_t *FromANSIToUNICODE(char *pData){int nLength = MultiByteToWideChar(CP_ACP, 0, pData,  - 1, NULL, 0);wchar_t *pwBuffer = new wchar_t[nLength + 1];memset(pwBuffer,0,sizeof(wchar_t)*(nLength + 1));MultiByteToWideChar(CP_ACP, 0, pData,  - 1, pwBuffer, nLength);return pwBuffer;}
