[VB6] Ubound error

[fox80129]

salve ragazzi,
Ho uno script che esegue un confronto tra due file di testo....
ma purtroppo mi da sempre un errore su Ubound:

Subscript out of range : "Ubound"

Questo è lo script completo...spero possiate aiutarmi:

Dim OggFile, origine, OggTextStream 
Set IISOBJ = getObject("IIS://LocalHost/W3SVC") 
origine="c:\textstream.txt" 
Set fso = CreateObject("Scripting.FileSystemObject") 
fso.CreateTextFile (origine) 
Set OggFile = fso.GetFile (origine) 
Set OggTextStream = OggFile.OpenAsTextStream(2) 
For each Object in IISOBJ 
         if (Object.Class = "IIsWebServer") then 
 WScript.Echo "WWW Site: " & Object.Name & " - " & Object.ServerComment

OggTextStream.WriteLine "WWW Site: " & Object.Name & " - " & Object.ServerComment
        end if 
Next 

OggTextStream.close 
dim filename1
dim filename2

filename1="c:\textstream.txt"
filename2="c:\sitelist.txt"


Set oFSO1 = CreateObject("Scripting.FileSystemObject")
Set oFSO2 = CreateObject("Scripting.FileSystemObject")

Set oTextFile1 = oFSO1.OpenTextFile(filename1, 1 , True)
Set oTextFile2 = oFSO2.OpenTextFile(filename2, 1 , True)

'riempiamo il primo array
dim newarray(1000)

	line1 = oTextFile1.ReadLine
	i = i +1
	if (line1<>"") then
		newarray(i) = line1
	end if
wend

'riempiamo il secondo array
dim oldarray()
i=0
While oTextFile1.AtEndOfStream <> True
	line1 = oTextFile2.ReadLine
	i = i +1
	if (line1<>"") then
		oldarray(i) = line1
	end if
wend

oTextFile1.close
oTextFile2.close

   i=i+1
   if newarray(i)<>"" then

			c = c+1
			if oldarray(c)<> "" then

				if newarray(i)=oldarray(c) then
					flag = false
					'exit while
				end if
end if
		wend
		if flag then
