i i i

thanks in advance i got this code while googled but not working , in this code its giving errors like ManagementScope is not defined , ObjectQuery is not defined , I am not preferring this code, any help will be appreciated.

Imports System.Management

Public Class Form2

Private Sub Button1\_Click( \_
    ByVal sender As System.Object, \_
    ByVal e As System.EventArgs \_
) Handles Button1.Click

    Dim ms As New ManagementScope("\\root\\cimv2")
    Dim oq As New ObjectQuery("Select \* from Win32\_Session")
    Dim query As New ManagementObjectSearcher(ms, oq)
    Dim queryCollection As ManagementObjectCollection = query.\[Get\]()

    For Each mo As ManagementObject In queryCollection
        If mo("LogonType").ToString().Equals("2") Then
            '  2 - for logged on User
            MessageBox.Show("Started Time: " + mo("StartTime").ToString)
        End If
    Next
End Sub

End Class

Any suggestions

Like Eddy said, explain what is not working; nobody can guess what is happening on your PC.

d@nish[^] has the answer.

Asking for help begins with "I tried X and it did Y instead of Z, where am I going wrong?". Try to explain what functionality you're after, as opposed to dropping a snippet with your needs. Is your computer in a domain (validating your credentials against some Windows Server) or on a workgroup? (local credentials) Write a console-app that gets launched when the user logs in (put a link in the startup folder). You could keep it running, doing nothing, and write down the time again when Windows closes your application (on shutdown, Windows informs your app why it's being closed) I'm not sure whether the Active Directory keeps this information around, but the above should work under all circumstances.

I haven't seen much of your dedication yet. Most of the time your message boils down to: "I found this code. It does not work. Help!" :~

I have also posted a possible solution to the stated problem. Didn't it work?

It often is not clear what you want. You seem to have an idea or a need, don't provide much information, don't tell what you have tried nor what exact problem you encountered, and sometimes you don't even ask a question at all. example 1[^] example 2[^] example 3[^] I suggest you improve your enquiring style and show more of what you tried, it will result in more, better, and sooner answers. :)

You really need to sit down with a beginners book on .NET and work through it. It appears that you're missing a reference to System.Management.dll.

Using the functions of the Math class[^]; there's examples on the bottom of that page.

You'd get more reactions if you started a new thread, and formulated a specific question on what you want help with ("Math" is a bit general)

Wrong deadline, especially at this price.
