The short answer is you can't, Shell.Exec can't be hidden, only Shell.Run supports that feature, the problem is you can't use Shell.Run to return info.

For the longer answer...
You can direct the output from Shell.Run to a text file and parse it from there:
Option Explicit

Function SystemOnline(ByVal ComputerName As String) As Boolean

    Dim oFSO As Object, oShell As Object
    Dim oTextFile As Variant
    Dim strName As String, strTempFile As String, strText As String, strcomspec As String

    Set oFSO = CreateObject("Scripting.FileSystemObject")
    Set oShell = CreateObject("Wscript.Shell")
    strcomspec = oShell.ExpandEnvironmentStrings("%comspec%")
    strName = oFSO.GetTempName
    strTempFile = strName
    oShell.Run strcomspec & " /c ping -n 3 -w 1000 " & ComputerName & " > " & strTempFile, 0, True
    Set oTextFile = oFSO.OpenTextFile(strTempFile, 1)
    Do While oTextFile.AtEndOfStream <> True
        strText = oTextFile.ReadLine
        If InStr(strText, "Reply") > 0 Then
            SystemOnline = True
            Exit Do
        End If
    Loop
    oTextFile.Close
    oFSO.DeleteFile (strTempFile)
End Function

Open in new window
