Use WMI to obtain system hardware and software related information in VB
Introduction:
WMI is a short written in English, which is mainly: access to some information and services to the local host, you can manage remote computers (of course you have to have enough permissions), such as: restart, shutdown, shut down process, create process Wait.
Examples are as follows:

Such as
Set wmiobjset = getObject ("WinMgmts: {ImpersonationLevel = Impersonate}"). _ Instancesof ("win32_printjob")
You can get information such as print task lists.
For VBs to get system hardware and software information, you use the API, and now use WMI to quickly implement our goal. If you get drive / graphics / sharing information, you will become convenient and effective.
