Accessing collections with FSO

[Steve]

I have a folder object whose associated files collection I can iterate
through using a "for each / next" loop to retrieve all the file names
individually. I cannot however directly access the n'th item in the files
collection? Here is my code so far;

' create FSO & folder objects
Dim objFSO
objFSO = Server.CreateOb ject("Scripting .FileSystemObje ct")
Dim objFld 'folder object &
objFld = objFSO.GetFolde r(Server.MapPat h("/test"))

' now directly access file # 4 & return file name
Return objFld.Files.It em(4).Name

This code snippet gives me a "parameter is incorrect" on the "return" line.

Any ideas? Thanks

Steve

Re: Accessing collections with FSO

hiya...

for starters i would use the My.Computer.Fil eSystem object, because the
Scripting.FileS ystemObject is extremely slow in .NET.

' make a read-only collection:
Dim files As ReadOnlyCollect ion(Of String)

' use My.Computer.Fil eSystem.GetFile s to return a ReadOnlyCollect ion of all
files in a folder.
' you can change the 2nd and 3rd parameters to suit:
files = My.Computer.Fil eSystem.GetFile s( folderpath,
FileIO.SearchOp tion.SearchAllS ubDirectories, anyWildcards)

' Display the FIFTH item:
msgbox files.item(4)

Re: Accessing collections with FSO

Hi Steve,

It seems that Files.Item() property requires name of the file passed,
bot it's number, e.g.:

~
MessageBox.Show (fso.GetFolder( "C:\").Files.It em("BOOTLOG.TXT ").Path)
~

Indeed, what is file #4? The don't have any order.


Also, I strongly advice you to use System.IO.Direc tory class for such
kind of jobs.

Hope this helps,
Roman

Re: Accessing collections with FSO

Hi, and thanks for the response & ideas.

I seem only able to "Dim" my collections as "ReadOnlyCollec tionBase" &

your "files = My.Computer.... " assignment gives me the "Name 'my' is not
declared" error.

I probably should mention that I am trying to implement this functionality
into a web control.

Any other ideas? Thanks, Steve
