VC++获取计算机Hardware Information (CPU ID, MainBoard Info, Hard Disk Serial, System Information)

1.计算机名称

 1 //计算机名称
 2 void DisplayComputerNameEx()

 7     GetComputerNameEx(ComputerNameNetBIOS, scComputerName, &lnNameLength);
 8 
 9     _tprintf( _T("Computer name: %s
"), scComputerName);
10 }

2.获取当前用户名（当前登录用户名）

 1 CString GetCurrentUserName()

 8     strUserName=szBuffer;  
 9 
10     delete szBuffer; 
11 
12     return strUserName;
