读取本机硬件信息的VBA代码

今天被朋友问到，如何在VB或者VBA代码中读取诸如硬盘或者CPU等硬件设备的序列号这一类信息。我写了一个范例如下

1. 在我的机器上运行的效果。我这个例子读取了四部分信息（CPU,物理硬盘，逻辑磁盘，网卡）

2.代码如下。代码的原理是使用WMI接口。需要管理员权限才能执行该代码

Private Type OSVERSIONINFO
                  dwOSVersionInfoSize   As Long
                  dwMajorVersion   As Long
                  dwMinorVersion   As Long
                  dwBuildNumber   As Long
                  dwPlatformId   As Long
                  szCSDVersion   As String * 128                   '     Maintenance   string   for   PSS   usage
  End Type
  Private Declare Function GetVersionEx Lib "kernel32" Alias "GetVersionExA" (lpVersionInformation As OSVERSIONINFO) As Long
  Private Declare Function GetComputerName Lib "kernel32" Alias "GetComputerNameA" (ByVal lpBuffer As String, nSize As Long) As Long
  Private Const VER_PLATFORM_WIN32_NT = 2
  Private Const VER_PLATFORM_WIN32_WINDOWS = 1
  Private Const VER_PLATFORM_WIN32s = 0
'''这个范例程序是读取CPU，物理硬盘，逻辑磁盘，和网卡的有关序列号的
