lRet = mciSendString("set cdAudio door Closed", 0&, 0, 0)
得到计算机IP和计算机全名
Dim MYIP As System.Net.IPHostEntry = System.Net.Dns.GetHostByName(System.Net.Dns.GetHostName)
MsgBox("您的IP地址：" & (MYIP.AddressList.GetValue(0).ToString))
MsgBox("您的计算机全名：" & (MYIP.HostName.ToString))
使用win32_operatingSystem (wmi Class)得到计算机信息
'添加ListBox在Form1_Load事件里，并引用system.Managment
Dim opSearch As New ManagementObjectSearcher("SELECT * FROM Win32_OperatingSystem")
Dim opInfo As ManagementObject
For Each opInfo In opSearch.Get()
