Stop Script Box Display During Ping Test

I am using a standard piece of code for a ping test but i would like to do it in the background without displaying the command box - how do i modify the script?

Function SystemOnline(ByVal ComputerName As String)

Dim oShell, oExec As Variant
Dim strText, strCmd As String
 
strText = ""
strCmd = "ping -n 3 -w 1000 " & ComputerName
Set oShell = CreateObject("WScript.Shell")
Set oExec = oShell.Exec(strCmd)
 
Do While Not oExec.StdOut.AtEndOfStream
    strText = oExec.StdOut.ReadLine()
    If InStr(strText, "Reply") > 0 Then
        SystemOnline = True
        Exit Do
    End If
Loop

End Function

Thanks
