-------------以上错误

-------------下面正确

hFile = CreateFile("D:\\dev\\fmt\\res\\face1.png", 0, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);

hFile = CreateFile(_T("D:\\dev\\fmt\\res\\face1.png"), GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, FILE_FLAG_BACKUP_SEMANTICS, NULL);

hFile = CreateFileW(L"D:\\dev\\fmt\\res\\face1.png", GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, FILE_FLAG_BACKUP_SEMANTICS, NULL);

hFile = CreateFile(".\\test.iobj", 0, FILE_SHARE_READ, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);

前面注释的都是错误的，对路径的写法有要求，一定要是\\
