Run script in background - windows-7

Question

I want to run following script as scheduled task on Windows 7 in background. Now, script displays cmd window and, can I run script without visible cmd window?
Option Explicit
Dim WshShell, oExec
Dim RegexParse
Dim hasError : hasError = 0
Set WshShell = WScript.CreateObject("WScript.Shell")
Set RegexParse = New RegExp
Set oExec = WshShell.Exec("%comspec% /c echo list volume | diskpart.exe")
RegexParse.Pattern = "\s\s(Volume\s\d)\s+([A-Z])\s+(.*)\s\s(NTFS|FAT)\s+(Mirror|RAID-5)\s+(\d+)\s+(..)\s\s([A-Za-z]*\s?[A-Za-z]*)(\s\s)*.*"
While Not oExec.StdOut.AtEndOfStream
Dim regexMatches
Dim Volume, Drive, Description, Redundancy, RaidStatus
Dim CurrentLine : CurrentLine = oExec.StdOut.ReadLine
Set regexMatches = RegexParse.Execute(CurrentLine)
If (regexMatches.Count > 0) Then
Dim match
Set match = regexMatches(0)
If match.SubMatches.Count >= 8 Then
Volume = match.SubMatches(0)
Drive = match.SubMatches(1)
Description = Trim(match.SubMatches(2))
Redundancy = match.SubMatches(4)
RaidStatus = Trim(match.SubMatches(7))
End If
If RaidStatus <> "Healthy" Then
hasError = 1
'WScript.StdOut.Write "WARNING "
MsgBox "Status of " & Redundancy & " " & Drive & ": (" & Description & ") is """ & RaidStatus & """", 16, "RAID error"
End If
End If
Wend
WScript.Quit(hasError)
Thanks a lot

Option 1 - If the task is running under your user credentials (if not, msgbox will not be visible)
There are two possible sources for the cmd window.
a) The script itself. If the task is executing cscript, the console window will be visible, avoid it calling wscript instead
b) The Shell.exec call. The only way to hide this window is to start the calling script hidden. On start of your script test for the presence of certain argument. If not present, make the script call itself with the argument, using Run method of the WshShell object, and indicating to run the script with hidden window. Second instance of the script will start with the special parameter, so it will run, but this time windows will be hidden.
Option 2 - Running the task under system credentials.
In this case, no window will be visible. All will be running in a separate session. BUT msgbox will not be seen. Change MsgBox call with a call to msg.exe and send a message to current console user.
