C++中char*转换为LPCWSTR的解决方案

int MultiByteToWideChar(  UINT CodePage,   // code page  DWORD dwFlags,   // character-type options  LPCSTR lpMultiByteStr, // string to map  int cbMultiByte,  // number of bytes in string  LPWSTR lpWideCharStr, // wide-character buffer  int cchWideChar  // size of buffer ); 

  char* szStr = "测试字符串"; WCHAR wszClassName[256]; memset(wszClassName,0,sizeof(wszClassName)); MultiByteToWideChar(CP_ACP,0,szStr,strlen(szStr)+1,wszClassName,  sizeof(wszClassName)/sizeof(wszClassName[0])); 

  char* szStr = "测试字符串";  CString str = CString(szStr); USES_CONVERSION; LPCWSTR wszClassName = new WCHAR[str.GetLength()+1]; wcscpy((LPTSTR)wszClassName,T2W((LPTSTR)str.GetBuffer(NULL))); str.ReleaseBuffer(); 

char* szStr = "测试字符串";  CString str = CString(szStr); USES_CONVERSION; LPCWSTR wszClassName = A2CW(W2A(str)); str.ReleaseBuffer();
