I'm not exactly certain what you want to happen when the file changes,
but here is one example that should give you all the pieces you
need ...
Dim objWMIService, objLatestEvent, colMonitoredEvents, _
objEvent, strComputer, oDisplay, sUserName, sTestName
sTestName = "test\jdoe"
strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" & _
strComputer & "\root\cimv2")
Set colMonitoredEvents = objWMIService.ExecNotificationQuery _
("SELECT * FROM __InstanceModificationEvent WITHIN 10 WHERE " _
& "TargetInstance ISA 'CIM_DataFile' and " _
& "TargetInstance.Name='C:\\scripts\\index.vbs'" )
Do
' Waits here for next event to occur
set objLatestEvent = colMonitoredEvents.NextEvent
'
With CreateObject("Scripting.FilesystemObject")
sText = .OpenTextFile("C:\scripts\index.vbs", 1).ReadAll
end with
sUsername = lcase(split(split(sText, "username=")(1), vbnewline)(0))
if sUsername <> sTestName then
sTestName = sUsername
set oDisplay = HTABox("lightgrey", 100, 300, 400, 500)
with oDisplay
.document.title = "Username Change"
.msg.innerHTML = "<input type=button id=btn " _
& "style='background-color:green' " _
& "value='Username Changed' title='Click to
close' " _
& "onclick='vbscript:done.value=true'><br>" _
& sUsername
wsh.sleep 3000 ' 3 second delay
.done.value = true
.close
end with ' oDisplay
end if
Loop
' Author Tom Lavedas, June 2010
Function HTABox(sBgColor, h, w, l, t)
Dim IE, HTA, sCmd, nRnd
randomize : nRnd = Int(1000000 * rnd)
sCmd = "mshta.exe ""javascript:{new " _
& "ActiveXObject(""InternetExplorer.Application" ")" _
& ".PutProperty('" & nRnd & "',window);" _
& "window.resizeTo(" & w & "," & h & ");" _
& "window.moveTo(" & l & "," & t & ")}"""
with CreateObject("WScript.Shell")
.Run sCmd, 1, False
do until .AppActivate("javascript:{new ") : WSH.sleep 10 : loop
end with ' WSHShell
For Each IE In CreateObject("Shell.Application").windows
If IsObject(IE.GetProperty(nRnd)) Then
set HTABox = IE.GetProperty(nRnd)
IE.Quit
HTABox.document.title = "HTABox"

& "window.event.returnValue=false:" _
& "done.value=true:end if'>" _
& "<input type=hidden id=done value=false>" _
& "<center><span id=msg> </span><center></body>"
Exit Function
End If
Next
' I can't imagine how this line can be reached, but just in case
MsgBox "HTA window not found."
wsh.quit
End Function
It uses a display function that I wrote a while back that is based on
an HTA, rather than IE. It allows the removal of all of the 'chrome'
normally associated with the use of IE. I wouldn't advise messing
with the Function. Instead, make your changes to function's input
parameters and the definition of the oDisplay.msg element (an HTML
span block) that is exposed by the function.
Note that the script runs forever, as written. It can only be stopped
using the Task Manager, taskkill.exe at the command prompt or through
the WMI Win32_Process class. It normally sits at the line marked,
opens the display box and leaves it open for a period of time (note
the wsh.sleep line) when the file is changed and then closes the box.
The delay can be changed. As written, the user can also close the
window by pressing the button.
As I said, it may not be exactly what you wanted, but it's a start.
