VB中使用WMI获取系统硬件和软件有关信息

在VB中使用WMI获取系统硬件和软件有关信息

简介:

      WMI是英文Windows Management
      Instrumentation的简写，它的功能主要是：访问本地主机的一些信息和服务，可以管理远程计算机（当然你必须要拥有足够的权限），比如：重启，关机，关闭进程，创建进程等。

实例如下:

'用WMI,先工程-引用 Microsoft WMI Scripting V1.1 Library

说明:

大家可能会发现一个规律,实际上WMI对信息的提取都是使用了WIN32_类库名这样的规律,下列表格就是微软的操作系统各种硬件类的描述

其它WMI管理的类的信息在

                          InstancesOf("Win32_PrintJob")

可以获得打印任务列表等信息

 

对于VB来讲获得系统硬件和软件信息大都使用API,现在使用WMI可以快速的实现我们的目标.如获取驱动器/显卡/共享信息等等都会变得方便和有效
