Reference a virtual folder

[David C]

Is the sample below valid for referencing a virtual folder named OracleFiles
in a web site where the aspx page that is using this code is under the root
folder of the subweb? Some users are getting exception errors. Thanks.

Dim strPath As String = Server.MapPath( "~/OracleFiles")

Some users are getting exception errors.

When posting to a technical newsgroup because users are getting errors, it's
really important to actually say what the errors are...

Server.MapPath doesn't always return what you think it should:

http://bytes.com/forum/thread53065.html

If you set a breakpoint on the line in question and inspect
Server.MapPath( "~/OracleFiles"), what does it show? Is it correct?

What does Request.ServerV ariables("APPL_ PHYSICAL_PATH ") return? Is that
correct?

Re: Reference a virtual folder

From the stack it doesn't appear to be in this function. I would say rather
that you do a recursive search and that it could fail if the user is not
allowed to browse all directories or if some other users remove a directory
when another one is doing something.

If it always fails for a given user, it would be a clue...

Plus in case you can just make sure (we just stuff this value in a session
variable and this is shown our next error report allwing us to check if
needed if the value is correct).

To add to Mark and not sure what is his intent, but it doesns't seems to be
a bug in Server.MapPath but rather that it was misued by the user. You
correctly used ~/ so it will return the path for OracleFiles under your
application root (and not under the site root whihc could cause a problem).

Moreover this is the kind of server side code that is not user dependent. So
the problem IMHO is definitely not with Server.MapPath. ..

Re: Reference a virtual folder

Here is the lines of code that are part of the problem. The user tells me
that the error is intermittant and apparently is only happening to 1 user.
The process is in the Page_Load event where I am checking to see if any .txt
files exist in a virtual folder to give a warning that there are unprocessed
files that need attention.

If Page.IsPostBack = False Then
'1st time in page so check for Oracle import files
Dim strPath As String = Server.MapPath( "~/OracleFiles")
'Use shared function in UtilClass to return count of txt files
Dim intFiles As Int32 = UtilClass.Files InPathType(strP ath,
"*.txt")
If intFiles 0 Then
If intFiles = 1 Then
txtMsg.Text = "There is 1 Oracle check request import
file to be processed."
Else
txtMsg.Text = "There are " & intFiles.ToStri ng & "
Oracle check request import files to be processed."
End If
End If
End If

I wonder if it would be a problem if someone deleted any .txt files a split
second before this process was checked by another user? Thanks.

Here is the lines of code that are part of the problem.

A couple of questions:

1) Do you know which specific line throws the exception?

2) Do you have exception handling around this code?

Re: Reference a virtual folder

From the stack this is inside UtilClass.Files InPathType(strP ath, "*.txt")...
likely in a GetFiles method...
