Question WMI equivalents in WMI.Net

[mellomel70]

Hi - I'm writing a script that will identify remote logons. I've done this before successfully with WMI, but I need to use WMI.Net this time around. For why, see WMI calls ignored outside of VisualStudio. Anyway, I have code that works, but I need to output some data, specifically a network user ID, and I'm not sure what I need to do in WMI.Net to accomplish this. Here's my old WMI code (objItem.Name is what I need to get at):

Dim strComputer As String = "."
Dim objWMIService As Object = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Dim colSessions As Object = objWMIService.ExecQuery("Select * from Win32_LogonSession Where LogonType = 10")
Dim objSession As Object
For Each objSession In colSessions
  Dim colList As Object
  colList = objWMIService.ExecQuery("Associators of " & "{Win32_LogonSession.LogonId=" & objSession.LogonId & "} " & "Where AssocClass=Win32_LoggedOnUser Role=Dependent")
  Dim objItem As Object
  For Each objItem In colList
    If objItem.Name = Session("UserEID") Then
      'Do Something
    End If
  Next

Here's the WMI.Net version:

Dim query As ObjectQuery
query = New ObjectQuery("Select * from Win32_LogonSession Where LogonType = 10")
Dim searcher As ManagementObjectSearcher
searcher = New ManagementObjectSearcher(query)
Dim queryCollection1 As ManagementObjectCollection = searcher.Get()
' Get the resulting collection and loop through it
Dim mo As ManagementBaseObject
For Each mo In queryCollection1
  query = New ObjectQuery("Associators of " & "{Win32_LogonSession.LogonId=" & mo("LogonId") & "} " & "Where AssocClass=Win32_LoggedOnUser Role=Dependent")
Next

Dim searcher2 = New ManagementObjectSearcher(query)
For Each objItem As ManagementObject In searcher2.Get()
   If objItem.Name = Session("UserEID") Then
      'Do Something
    End If
Next

In the .Net world objItem doesn't have a Name property. Where can I go to find what the properties of this object are in WMI.Net and which one I should be using to get the user's network ID?

Thanks!

Haven't tested it out but my kneejerk reaction is to say objItem("Name").

If you're going to be doing a large amount of WMI scripting this thread may be of use to you: http://www.vbdotnetforums.com/articles-interest/13972-wmi-code-creator-1-0-a.html

Matt - thanks, objItem("Name") is indeed the answer. Now I've got another problem: my query is no longer returning remote users. As a matter of fact, it's returning a user who isn't logged into the server at all, and not showing users who are actually logged in remotely (me, for example). Has WQL also changed in .Net? Any ideas are welcome, or any links to WMI.Net documentation that might actually be helpful. Thanks!

Never mind - a reboot of the server seems to have solved the problem. All is well, for now, at least. Thanks for your help.
