VBScript Permission Problem

I am trying to write some VBScript to cycle through all of the directories on my machine, find any files which have been modified in the last hour and output the full filename to a text file in it's current location. The file works fine when sat in a folder on my machine but as soon as I drop it on the root dir I get permission errors. I think this must be because I don't have read permissions on certain directories, is there a way around this? My code is below:

Dim sCurPath
sCurPath = CreateObject("Scripting.FileSystemObject").GetAbsolutePathName(".")
'createDirectory = "C:\Documents and Settings\T104ahe\Desktop\Menu\TestScript\myNewFolder"
createFile = "\Modified_Files_List.txt"

' Create the File System Object
Set createobjFSO = CreateObject("Scripting.FileSystemObject")

'Set createobjFolder = createobjFSO.CreateFolder(createDirectory)
Set createobjFile = createobjFSO.CreateTextFile(sCurPath & createFile)
Wscript.Echo "File: " & createDirectory & createFile & " successfully created."

'--------------------------------------------------------

hourAgo = DateAdd("h", -1, Now)
'destDir = "C:\Documents and Settings\T104ahe\Desktop\Menu\TestScript\filesModified"

strFolder = sCurPath
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFolder = objFSO.GetFolder(strFolder)
'WScript.Echo objFolder.Path

Set colFiles = objFolder.Files

For Each objFile In colFiles
      If objFile.DateLastModified > hourAgo Then _
            createobjFile.WriteLine(objFile.path)
Next

ShowSubFolders(objFolder)

Sub ShowSubFolders(objFolder)
Set colFolders = objFolder.SubFolders
For Each objSubFolder In colFolders
'WScript.Echo objSubFolder.Path
Set colFiles = objSubFolder.Files
For Each objFile In colFiles
       If objFile.DateLastModified > hourAgo Then _
            createobjFile.WriteLine(objFile.path)
Next
ShowSubFolders(objSubFolder)
Next
End Sub

The script will start at the current directory the script is in, given by this line:
sCurPath = CreateObject("Scripting.FileSystemObject").GetAbsolutePathName(".")

if you need the script in the root folder, but want to start at a subfolder, then use
sCurPath = "C:\MyFolder"

But, ultimately, if you don't have read permissions, you will need to use an account that does.

You could add error trapping so that the script would continue by skipping any file or folder it couldn't read, but it still relies on the permission your current account has.

Hi Rob, how would I do the error trapping as I'm not fussed to much about the ones I can't access but I want the script to continue to cycle through. At present it dies as soon as it hits an error.

Something like this should do. I've just added a simple error check to the ShowSubFolders routine.

Dim sCurPath
sCurPath = CreateObject("Scripting.FileSystemObject").GetAbsolutePathName(".")
'createDirectory = "C:\Documents and Settings\T104ahe\Desktop\Menu\TestScript\myNewFolder"
createFile = "\Modified_Files_List.txt"

' Create the File System Object
Set createobjFSO = CreateObject("Scripting.FileSystemObject")


'Set createobjFolder = createobjFSO.CreateFolder(createDirectory)
Set createobjFile = createobjFSO.CreateTextFile(sCurPath & createFile)
Wscript.Echo "File: " & createDirectory & createFile & " successfully created."

'--------------------------------------------------------

hourAgo = DateAdd("h", -1, Now)
'destDir = "C:\Documents and Settings\T104ahe\Desktop\Menu\TestScript\filesModified"

strFolder = sCurPath
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFolder = objFSO.GetFolder(strFolder)
'WScript.Echo objFolder.Path

ShowSubFolders(objFolder)

Sub ShowSubFolders(objFolder)
    On Error Resume Next
    Set colFiles = objSubFolder.Files
    For Each objFile In colFiles
         If objFile.DateLastModified > hourAgo Then _
            createobjFile.WriteLine(objFile.path)
    Next
  Set colFolders = objFolder.SubFolders
  For Each objSubFolder In colFolders
    'WScript.Echo objSubFolder.Path
    ShowSubFolders(objSubFolder)
  Next
  If Err.number <> 0 Then WScript.Echo "Error reading " & objFolder.Path
  Err.Clear
  On Error GoTo 0
End Sub

This script no longer works, it just tells me the errors and doesn't write the required data to the file. Can you have another look please?

Hi Rob, that's great, thanks. 2 minor points though when you get 5 then I'll close this thread....

1. I don't want it to echo the error, as there will be lots, can I just comment out these lines?
If Err.number <> 0 Then WScript.Echo "Error reading " & objFolder.Path
Err.Clear

2. What is this part doing?
If Right(sCurPath, 1) = "\" Then sCurPath = Left(sCurPath, Len(sCurPath) - 1)
createFile = "\Modified_Files_List.txt"

RobSampson

Hi,

1. Yes, but you can leave in Err.Clear...that only clears the error state

2. The first line there ensures that the value in sCurPath *does not* end in a backslash. This is done so that we *know* in the next line, we must put backslash then the file name. I just do this as a matter of practice because from experience, a lot of people will have, say
sCurPath = "C:\MyFolder\"
createFile = "\MyFile.txt"
and then, when those two are put together, you end up with two backslashes together, which results in an error.

Regards,

Rob.
