What code will run my function in multiple threads?

Last Modified: 2016-07-05
Hello.  I have written a function here in VB.NET that basically remotely connects to a computer and checks on the percent bitlocker complete status on the machine which takes a long time encrypting a boot drive of course.  i'm having to encrypt many machines and wrote this to let me know the status of each one.  Can anyone add the code here that will basically let me pass a list of computer names to my function and have it run in separate threads?  one per name...the list of computer names can be in an array or i  may just put them in a listbox or something...not sure on that yet

Here is the function and i currently call it as: show_progress("211mt03", 15, 15)  ....("computername", x,y)  x and y are the positions of the progress bar which i haven't figured that out yet actually.

Private Function show_progress(ByVal cname As String, ByVal x As Integer, ByVal y As Integer)
        Dim p1 As New ProgressBar
        Dim myConnectionOptions As New System.Management.ConnectionOptions
        With myConnectionOptions
            .Authentication = System.Management.AuthenticationLevel.Connect
            .Authentication = System.Management.AuthenticationLevel.PacketPrivacy
        End With
        Dim strComputer = cname
        Dim colItems As ManagementScope
        colItems = New ManagementScope("\\" & strComputer & "\root\CIMV2\Security\MicrosoftVolumeEncryption", myConnectionOptions)
        If colItems.IsConnected = False Then
            MsgBox("Could not connect to WMI namespace")
        End If
        Dim query As ObjectQuery
        query = New ObjectQuery( _
            "SELECT * FROM Win32_EncryptableVolume")
        Dim searcher As ManagementObjectSearcher
        searcher = _
            New ManagementObjectSearcher(colItems, query)
        Dim queryCollection As ManagementObjectCollection
        queryCollection = searcher.Get()
        Dim m As ManagementObject
        For Each m In queryCollection
            Dim ConversionStatus As ManagementBaseObject = m.InvokeMethod("GetConversionStatus", Nothing, Nothing)
            Label1.Text = ConversionStatus("EncryptionPercentage").ToString & "%"
            '  ProgressBar1.Value = ConversionStatus("EncryptionPercentage")
            p1.Size = New Size(242, 24)
            p1.Location = New Point(x, y)
            p1.Value = ConversionStatus("EncryptionPercentage")
            p1.Visible = True
    End Function
