Please explain what "Empty path has no directory" means with Server.MapPath

Hello,

I have the following line of code in a script...

litMsg.Text = Server.MapPath("/");

where litMsg is an ASP.Net Literal control. When I try and run this
page, I get the error ...

System.ArgumentException: Empty path has no directory.

Anyone any idea what this means? I have used Server.MapPath many times
before without error, I'm not sure why it suddenly stopped working here.

I'm sure I'm missing something blindingly obvious and would be grateful
if anyone could point it out!! TIA.

(anything added below this line is nothing to do with me)IN case it's of any use to anyone, I found out that the problem was
caused by me having the following two lines in Page_Load...

HttpContext myContext = HttpContext.Current;
myContext.RewritePath("/");

I'm not actually sure *why* I had those lines there, they must have been
from something I was doing before. As soon as I removed them, the
Server.MapPath worked fine.

If anyone has an explanation, I would like to hear it ;-)

Please help - weird problem

Hi,
While trying to create new directory i recieve the following error
message:
"System.IO.DirectoryNotFoundException: Could not find a part of the path
"\\premfs16\sites".
The path exists, even when i check the path
with the code: Directory.Exists(...) the result is true.

Here is the code:
http://www.adeo.co.il/test.aspx

Notice that in the line before the code throws exception
i create new file to the same path and no error
occurs - only when trying to create directory
the error appears.

Any idea?Yoni,

This is a security problem. You need to grant read permission for
\\premfs16\sites to the ASP.NET user.

So how do you explain that the code succeeded creating
a file (which needs to read the same path...) and only
creating a directory failed?

Yoni,

Probably file creating doesn't require read permission but directory
creating does. I don't know exactly how all these permissions work.

Security and permission setting is a complicated matter. You don't really
need to understand fully the theoretical background. For your immediate
problem it's enough to know how other people solved the same problem. If you
wish to investigate - you are welcome to invest your time in that.

The problem is much more sophisticated.
My web site host at shared hosting company.
No hosting company will allow users to have read
permissions on their root directory.
So what you are actually saying is that you can not
open directories on web sites which hosts on shared servers.
Is that correct?

Well, I don't think you need read permissions for the root directory, only
for those under yours. Speak to your host and ask again on security
newsgroups.

Good luck,

Please help a newbie...

I cannot for the life of me figure out why I cannot run an ASP.NET app. Everytime I try to view in browser/debug I get the error:

maps to a directory outside this application, which is not supported.

I am using Visual Studio 2003. Could someone please enlighten me on what is going wrong here. I am a newbie so if the solution is simple please forgive my ignorance...thanksI have never heard of this error, and it isn't documented in MSDN. My guess is there is a mis-configuration in IIS. Sorry I can't be more specific.
Can you show sources for the page you are trying to view? Especially parts referring to elsewhere (like trying to reference user control etc)

Maybe you can have a look at the following post:

App_GlobalResources maps to a directory outside this application, which is not supported

Hope this helps,

Regards

thanks for posting that link...that is exactly what the problem was. I had a "\" at the end of the file path for the home directory...

thanks again, you saved me

That is so cool

I am happy you solved your problem.

Regards

Hi,

I have just deployed my private assembly in the bin directory of my ISP and
I am getting the following error. I am pretty sure it is able to find my
assemblyPLEASE tell me how can I find which dependencies are not being
found( is there a way to trace the dependencies which are not found).
I Just have ftp access to my isp server.

Thanks you in advance,
Peace,
Raj.
