Monitoring Drives with WMI

由 醉酒当歌 提交于 2019-12-09 00:46:52

I wrote a quick proof of concept using the ManagementOperationObserver and it partially works. Right now (with the code below), I am getting all sort of events. I would like to get only events when a drive is connected and disconnected. Is there a way to specify this in the Wql Query? Thanks! private void button2_Click(object sender,

问题 I have a workgroup of web servers running Server 2008 R2 in which I'm trying to manage a script that checks the disk space of all of them.

The script is a C# ASP.NET page, though I've tried comparable calls in PowerShell and it gives the same error. The script works fine to access the information for the

问题 Okay, so I've read up on calling functions and passing parameters in powershell but maybe I'm not understanding something. I am calling a function and passing a couple parameters and everything works fine. It is variable defined within the function that seems to be null when it isn't.
