System.IO.IOException

Hi all,

Yesterday we upgraded our server to the 1.1 Framework. (from 1.0)
Our project was also converted in Visual Studio to 1.1

Since we have uploaded the project, we are getting an error with one of our
pages which is trying to read a list of files from a network share and
populate a dropdownlist.

The error is:

System.IO.IOException: The specified network name is no longer available.

OR

System.IO.IOException: The specified network password is not correct.

The code is:

Dim fileEntries As String() = Directory.GetFiles(targetDirectory)

where targetdirectory is "\\192.168.1.1\data\General\Documents\"

If we try to view the page on our own machines ie http://localhost the page
works fine!!

So is there any fixes/ideas why this is happening!!

Thanks!How would you get TWO different error messages from the same code?

If I knew that then I wouldn't have the problem ;)

System.IO.IOException: Cannot create a file when that file already exists.

Getting the following error on my production server whether the file exists
or not:

"System.IO.IOException: Cannot create a file when that file already exists."

Here's the code generating the error (seems to be happening when I try
creating a directory)

If dirmgr.Exists("s:\blah\" & txt_name.Text) Then
lblerror.Text = lblerror.Text & "Unable to build physical path. " &
txt_name.Text & " & Contact Dev Team. "
Else
dirmgr.CreateDirectory("s:\blah\" & txt_name.Text)

This code runs fine on my development server (only the path is c:\blah\blah
instead of S). Also, my production server has failover cluser, and the s
drive is the failover drive. I can't imagine that could be a problem, but
thought I would mention it.

Asside from that, the only other thing I can think of is that the framework
version on my dev box says 1.1, and the one on my production server says:
1.0.37 - surely that's not the cause is it? Permissions shouldn't be an
issue (i've even tried as domain admin)

I would appreciate any help on this, as I'm out of ideas, and can find no
other documentation on this.

I agree with Natty. The problem you are having is most likely caused by
having no right to access network resources. Willy address a similar
problem before. See

Thanks for the response.

I understand that, but I'm trying to create a directory on the local drive.
This isn't a mapped share. The drive is physically present on the web
server, and if that web server fails, the other system physically takes over
the drive (ie, a cluster). I've also added the local ASPNET account to the
NTFS permissions on the folder, and it still fails.

It doesn't work creating folders under the same directory as the web
application... same issue.

I'm going to try figuring out why that server is showing that it's running
version 1.03 of the dotnet framework. It shows that v1.1 was installed.

Thanks,
Chad

Chad, was the problem resolved? It seems that you installed both v1.03 and
v1.1 on the same web server. If so, it might be helpful to look at the
article "Compatibility Considerations and Version Changes" on
http://www.gotdotnet.com/team/changeinfo/default.aspx. Try configuring your
web application to run V1.03 and V1.1 specifically to see how it works.

Allen,

Thanks for the followup. I actually got my program working late last night.
The problem was the framework version.

I tried simply configuring the web application to use version 1.1, but that
didn't help. I also tried uninstalling then reinstalling framework version
1.1, but that also didn't get IIS to start using version 1.1 by default. I
consequently uninstalled versions 1.1 *and* version 1.03, then only
reinstalled version 1.1 again, and this took care of the problem.

Thanks again for all the help everyone!

- Chad

System.IO.IOException: The filename, directory name, or volume label syntax is incorrect.

System.IO.IOException: The filename, directory name, or volume label
syntax is incorrect.

I have hit a problem for which I can find no solutions. Has anyone any
ideas?

I am writing XML into a Memory STream and using a Transform to make
HTML. This works fine normally, but I have no the above stated error.

I did get some odd chars in the HTML name which caused a problem,
which I corrected. The current error seems to random. I am wondering
if memory is the problem, or disk space.

Last Trace - html 2-->../Grohe/Grohe-Sundries-Handles-Handles-Automatic-2000-47255000.html<--
shows the filename

Code:

string HTMLName = xmlName;

Trace.Warn ("html--" + HTMLName);

string thisManNameDir = thisManName;
thisManNameDir = thisManNameDir.Replace(" ","");

HTMLName = "../" + thisManNameDir + "/" + HTMLName;
Trace.Warn ("html 2-->" + HTMLName + "<--");
//Trace.Warn("writing html" + HTMLName );
XmlUrlResolver resolver = new XmlUrlResolver();

string thisURL1 = Request.Url.ToString();
Trace.Warn("header " + thisURL1);
thisURL1 = thisURL1.Replace("/myxml/Xml1.aspx","");
string thisURL = thisURL1.Replace("http://","");

thisURL1 = thisURL1.Replace(".co.uk","");
thisURL1 = thisURL1.Replace(".com","");
thisURL1 = thisURL1.Replace(".biz","");

thisURL1 = thisURL1.Replace("http://www.","");
string thisDomain = thisURL1.Replace("http://","");

NetworkCredential cred = new
NetworkCredential(thisDomain,"pwd",thisURL);

thisStream.Position = 0;
Trace.Warn("a");
//XmlTextReader myTxtReader = new XmlTextReader (thisStream);

Trace.Warn("a1");
string xslPath = Server.MapPath("myXSL.xsl");
Trace.Warn("a2");
string htmlPath = Server.MapPath(HTMLName);
Trace.Warn("a3");
XPathDocument aXPathDocument = new XPathDocument(thisStream);
Trace.Warn("a4");
XslTransform transform = new XslTransform();
Trace.Warn("a5");
transform.Load(xslPath, resolver);

StreamWriter aStreamWriter = new StreamWriter(htmlPath);

Trace.Warn("a6");

transform.Transform(aXPathDocument,null,aStreamWri ter, resolver);

aStreamWriter.Flush();
aStreamWriter.Close();

Trace.Warn("a7");
//Trace.Warn("ending html");

}I solved this.

Hello. I know it's been almost 3 years since this post, but I'm experiencing the same problem that you had and you're the only person who seems to have an idea on how to fix it. Do you remember what your problem was and how you resolved it?

Thanks in advance.
