Uploading files to a virtual directory

[B Letts]

Hi -

I'm currently using the FileUpload control to allow people to upload
files to my website. This all works fine, as long as I'm going to a
physical path on my server.

However, I need to allow people to upload to a virtual directory. The
directory may or may not exist on the same server as the Web site.

I can't seem to figure out how to do this. If I pass the virtual
directory address to FileUpload.Save As, it tells me I need a rooted
directory. If I try to get the physical directory name from
Server.MapPath, it throws an exception.

Is there any way to either get the physical path to a virtual directory
so I can pass it to FileUpload.Save As, or an alternative method to
upload/delete files to and from a virtual directory?

Thanks in advance.

Server.MapPath should work. What exception do you have ? Could it be a
permission issue ?

It will have to be accessible at the file system level from the server to
upload it. You can use the MapPath() to convert the http path to a file
system path but the server has to have that file system path accessible to
it....

I don't get an exception from Server.MapPath, but I also don't get the
correct physical path.

I set up a virtual directory in IIS. Let's say I call it
MyVirtualDirect ory and it points to d:\MyFiles.

If I try to find the physical path of MyVirtualDirect ory like so:

Server.MapPath( "MyVirtualDirec tory")

It returns my current application physical directory with
"MyVirtualDirec tory" appended on the end, for example,
"C:\MyASPNETPro jects\ThisProje ct\MyVirtualDir ectory"

Maybe this is a setup issue? The ultimate goal is to allow the users to
upload files to wherever the virtual directory points - which may be a
directory on the same server, or a different one altogether.

What if you try "/MyVirtualDirect ory" or "~/MyVirtualDirect ory" instead ?

IMO Server.MapPath resolves the root and then add the relative path
resolving the relative path to a local directory.
Using an absolute path should hopefully solve this issue.

Try
Server.MapPath( "/MyVirtualDirect ory") and see what you get.

That's fine. I assume the server has to have the file system path
accessible in order to set it up as a virtual directory to begin with,
correct?

What, then, is the format I need to pass to MapPath to get the physical
address of the virtual directory? Everything I try appends the physical
directory of my ASP.NET project to the virtual directory.

IE: I have the virtual directory set as MyVirtualDirect ory, pointing to
D:\MyFiles.

My ASP.NET project lives in C:\MyProjects\P roject_1

If I try Server.MapPath( "MyVirtualDirec tory"), I get back
C:\MyProjects\P roject_1\MyVirt ualDirectory.

I need to get D:\MyFiles.

What am I doing wrong?

[Patrice]

Gave this a try and it works fine here even if relative ?

Does this physical directory exists ? If you have both a virtual and a
physical directory Server.MapPath might well favor the physical directory ?

Else double check your IIS configuration ? Is the site restarted since you
created the virtual directory ? If you type the URL in your browser can you
check if you reach the expected location ?

Good luck.

Nope. I get an InvalidOperatio nException if I try that.

Here's what I tried:

- Set up a Virtual Directory in IIS, called MyVirtualDirect ory. It
points to C:\temp. I gave it all permissions - read write browse execute
etc.

- pointing a browser to http://localhost/MyVirtualDirectory/ gives me a
file listing of the correct directory

- My ASP.NET project that I'm trying to acccess the virtual directory is
running from C:\MyProject
Server.MapPath( "MyVirtualDirec tory") gives me
"C:\\MyProject\ \MyVirtualDirec tory"

Server.MapPath( "\\MyVirtualDir ectory") gives me an
InvalidOperatio nException

Server.MapPath( "\MyVirtualDire ctory") gives me an unrecognized escape
sequence (no surprise)

Server.MapPath( "/MyVirtualDirect ory") gives me InvalidOperatio nException
and also says "Failed to map the path '/MyVirtualDirect ory'."}

Server.MapPath( "//MyVirtualDirect ory") gives me
InvalidOperatio nException and also says "Failed to map the path
'/MyVirtualDirect ory'."}
What else can I try? Could this be a permissions and/or setup issue?

That's odd, using :

Server.MapPath( "/MyVirtualDirect ory") works fine for me.

Server.MapPath( "/SomeOtherVirtua lDirectory/") works fine, too.

Server.MapPath( "/aDifferentVirtu alDirectory/somefile.ext") also works.
