Trust Level Error

[kennyaidan]

Hi,
I am trying to create aspx files and folders on an IIS server and i got the following error

Security Exception
Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: Exception from HRESULT: 0x800A0046 (CTL_E_PERMISSIONDENIED).

The code i used was
outputfile = fso.CreateTextFile("C:\Inetpub\

http://wwwroot\news\"

& storydate & "\" & storyfile & ".aspx", True)

Does anyone know how to change the trust level permissions on an IIS server so that i am able to create files and folders on it. At the moment the trust level within the machine.config file is set to "high". I have tried setting that to low and i still get the same error. Any help greatly appreciated.
Thanks
Aidan

Is this on a .NET server (.aspx) and are you trying to create the folders at the same time as the textfile?

Yes it is on a .NET server and i tried to create the folders before I create files in the code. The create folder code comes first in the file, it checks that this folder doesn't exist already and if not it then creates a new directory

If Not fso.FolderExists("C:\Inetpub\

http://wwwroot\news"

& storydate) Then
f = fso.CreateFolder("C:\Inetpub\

http://wwwroot\news"

& storydate)

then further down the code it creates a new aspx file to be placed into the newly created folder.

outputfilex = fso.CreateTextFile("C:\Inetpub\

http://wwwroot\news\"

& storydate & "\" & storyfile & ".aspx", True)

The error message appears at the create folder section doesn't even get down to the create file piece of code.

thanks

Not got into .net yet, but in the code you posted the "\"is missing from the fso.CreateFolder(...\news & storydate)

try this, (works for IIS5)

Dim AbsPath
'creating folder,
AbsPath = Server.MapPath("news&quot & chr(92) & storydate
If Not FSO.FolderExists(AbsPath ) then
FSO.CreateFolder(AbsPath )
End If

'create text file,
AbsPath = Server.MapPath("news&quot
set OutputFile = FSO.CreateTextFile(AbsPath & chr(92) & storydate & chr(92) & storyfile & ".aspx",True)

I found that with IIS I had to use '& chr(92) &' in
place '& "\" & '

Thanks Chris but i got an erro when i tried running that code - Line 51

Line 49: AbsPath = Server.MapPath("news&quot & chr(92) & storydate
Line 50: If Not fso.FolderExists(AbsPath) then
Line 51: fso.CreateFolder(AbsPath)
Line 52: End If

Exception from HRESULT: 0x800A004C (CTL_E_PATHNOTFOUND).

Do i need to declare Server.MapPath somewhere

 

[ChrisHirst]

Server.MapPath is a standard method for getting the absolute path to the folder or so doesn't need to be declared. I am assuming that M$ have not taken some of these methods out in their efforts to shape the world the .net way.

The only thing I can think of right now is to look at the NTFS permissions for the C:\Inetpub folder tree, and to make sure that the Anonymous username (usually IUSR_computername) has permission to write to and create folders and files in the subfolders.

maybe should have thought of that first!
