Using a timer to update form - VB.Net - vb.net

Question

I want to display the status of aspects of my application on a form.
I tried adding a timer to the form. Every 10 seconds the timer runs and checks a database for a particular status, then changes elements on the form based on the status.
This works fine for changing the colour of menu items, but when I try and make an image (in)visible on the form, I get a cross-thread error.
Should I be using a timer, Backgroundworker or something else?
Does someone have a basic bit of code that will do this elegantly?
Private WithEvents tmrMain As New System.Timers.Timer(10000)
Private Sub frmMaster_Load(sender As Object, e As EventArgs) Handles Me.Load
tmrMain.Enabled = True
tmrMain.Start()
End Sub
Private Sub tmrMain_Elapsed(ByVal sender As Object, ByVal e As System.Timers.ElapsedEventArgs) Handles tmrMain.Elapsed
Dim TRunning As Boolean = True
TRunning = BTools.CheckImportRunningStatus '' This gets the on/off status from the DB
If TRunning Then
miFileMYOBImport.ForeColor = Color.Red '' Change menu color
pbMYOBDownload.Visible = True '' Make image visible
Else
miFileMYOBImport.ForeColor = Color.DarkGreen
pbMYOBDownload.Visible = False
End If
End Sub

Try:
Private Sub MakeImageVisible(ByVal control As Control, ByVal visible As Boolean)
If control.InvokeRequired Then
control.BeginInvoke(New Action(Of Control, Boolean)(AddressOf MakeImageVisible), control, visible)
Else
control.Visible = visible
End If
End Sub
Private Sub tmrMain_Elapsed(ByVal sender As Object, ByVal e As System.Timers.ElapsedEventArgs) Handles tmrMain.Elapsed
Dim TRunning As Boolean = True
TRunning = BTools.CheckImportRunningStatus '' This gets the on/off status from the DB
If TRunning Then
miFileMYOBImport.ForeColor = Color.Red '' Change menu color
Else
miFileMYOBImport.ForeColor = Color.DarkGreen
End If
MakeImageVisible(pbMYOBDownload, TRunning) ' Make image visible or invisible
End Sub
