VB.NET: Check to see if process is running for current user only

Question

_{Wednesday, November 23, 2016 9:11 PM}

I am pretty new to vb.net and programming in general.

I am trying to create a function that looks to see if a process  is running for the current user only. So far I am able to check if the process is running just fine. But, if the process is running for a separate user, I will get a false positive.

Here is what i have so far:

    Dim p() As Process

   Private Sub CheckIfRunning(processname As String)
        'processname = "SLDWORKS"
        p = Process.GetProcessesByName(processname)
        If p.Count > 0 Then
            ' Process is running
            Console.WriteLine("Solidworks Is Running")
            'Else boolstatus = False

            boolstatus = True

        Else
            ' Process is not running
            Console.WriteLine("Solidworks Is Not Running")
            boolstatus = False
        End If
    End Sub

There are two methods described here.

WMI is simpler - the time it takes is not likely to be an issue. You could convert that code using an on-line code converter, or just rewrite it in VB as query process is the only important bit.

Hi kodybr,

Thank you for posting in MSDN Forum.

Use the following code snippet you could find the processes for the current user.

        Dim CurrentSessionID As Integer = Process.GetCurrentProcess.SessionId
        For Each proc As Process In Process.GetProcesses
            If proc.SessionId = CurrentSessionID Then
                MessageBox.Show(proc.ProcessName & " is running as the currently logged on user")
            End If
        Next

And this thread is about list processes for the current user in VB. You could check and refer that if it helps. 

Hope it will be helpful to you.

Best Regards,

Neda Zhang

You can see which users own a service (an executable is always only running for the current user). 

However, a service (process) can also be started by other users and still be used by more persons. 

AFAIK is in the OS no information available which processes are used by a more users at that moment. 

Otherwise we would not every time if we close Windows since windows 7 see that message which tells that it is possible that other users are also busy. Sometimes they make at Microsoft lazy made software, but not on that level and not during such a long time.
