Hi

I'm terying to programmatically determine information about scheduled task running in a Windows Server 2003 SP1 machine. I've created a vbscript (it will be run locally) which is failing at the following line

Set service = CreateObject("Schedule.Service")

error message is

Microsoft VBScript runtime error: ActiveX component can't create object: 'Scheduler.Service'

Now the same code works in a Vista machine. After googling I found out that an assembly called TaskScheduler.dll needs to be present in the machine for this code to work. I found this dll in the Vista machine (where its working) in the following location

C:\Windows\winsxs\msil_taskscheduler_31bf3856ad364e35_6.0.6001.18000_none_14fd1dd83f56d37e

But its absent in the 2003 machine. Does anybody know how you can get this dll? May be that will solve the problem. I found in one article that this dll comes from Microsoft Site Server 3.0. BTW, I tried putting the dll in the same location in the 2003 machine and registered it using regasm (regsvc was throwing error), although with a warning saying the tlb file was not registered. It still was not working.

Under OSs older than Vista you could use the code below. It uses schtask.exe
to obtain the details you're after.

'------------------------------------
'Display all selected scheduled tasks
'------------------------------------
Dim aTasks(100, 100), iTaskCount 'Array containing a list of all tasks
Set oWshShell = CreateObject("WScript.Shell")
Set oArgs = WScript.Arguments

AllTasks = (oArgs.Count = 0)
if not AllTasks then sTask = oArgs(0)
if sTask = "*" then AllTasks = True
If InStr(sTask, "?") > 0 Then Message "Usage: TaskLister [TaskName or *]
[Computer]"
if oArgs.count > 1 then sComputer = "/s """ & oArgs(1) & """" Else sComputer
= ""

Set oExec = oWshShell.Exec("schtasks.exe /query " & sComputer & " /v /fo
csv")
wscript.sleep 1000

oExec.StdOut.ReadLine 'Blank first line
ReadRecord aHeaders 'Read the headers record
ReadTasks
DisplayTasks

'--------------------------------------------
'Display full details of the selected task(s)
'--------------------------------------------
Sub DisplayTasks
found = False
For i = 0 To iTaskCount
If AllTasks Or (UCase(aTasks(i, 1)) = UCase(sTask)) Then
For j = 0 To UBound(aHeaders)
Desc = aTasks(i, j)
If Len(Desc) > 42 Then Desc = Left(Desc, 39) & "..."
WScript.Echo Left(aHeaders(j) & Space(37), 37) & Desc
Next
found = True
WScript.Echo
End If
Next
if not found then Message ("Task """ & sTask & """ not found.")
End Sub
'---------------------------
'Put all tasks into an array
'---------------------------
Sub ReadTasks
i = 0
Do While Not oExec.StdOut.AtEndOfStream
if i > 99 then Message "100 tasks processed - remaining taks (if any)
were ignored"
ReadRecord aTemp
For j = 0 To UBound(aTemp)
aTasks(i, j) = aTemp(j) 'Copy the temp array into the tasks array
Next
i = i + 1
Loop
iTaskCount = i - 1
End Sub
'-----------------------------------------------
'Read one record from the output of schtasks.exe
'-----------------------------------------------
Sub ReadRecord(aRecord)
aRecord = Split (oExec.StdOut.ReadLine, """,""") 'Split the CSV fields
For i = 0 To UBound(aRecord)
aRecord(i) = Replace(aRecord(i), """", "") 'Remove the remaining
quotes
Next
End Sub
'-------------
'Error message
'-------------
Sub Message (sLine)
WScript.Echo
WScript.Echo sLine
WScript.Quit
End Sub
