I use dynamic currency symbol(Doller,£,etc.,) for that the web config is updated in locally but in site I can not modifiy the web config file and I get the following error
"Attempted to perform an unauthorized operation."
I have a function that finds a files MIME type for download purposes. I use this DllImport:
Code:
[DllImport("urlmon.dll", CharSet = CharSet.Unicode, ExactSpelling = true, SetLastError = false)]
static extern int FindMimeFromData(IntPtr pBC,
[MarshalAs(UnmanagedType.LPWStr)] string pwzUrl,
[MarshalAs(UnmanagedType.LPArray, ArraySubType = UnmanagedType.I1, SizeParamIndex = 3)] byte[] pBuffer,
int cbSize,
[MarshalAs(UnmanagedType.LPWStr)] string pwzMimeProposed,
int dwMimeFlags,
out IntPtr ppwzMimeOut,
int dwReserved);
I use this function:
Code:
#region GetMimeFromFile(string)
public static string GetMimeFromFile(string file)
{
IntPtr mimeout;
if (!File.Exists(file))
{
throw new FileNotFoundException(file + " not found.");
} //if
int maxContent = (int)new FileInfo(file).Length;
if (maxContent > 4096)
{
maxContent = 4096;
} //if
byte[] buff = new byte[maxContent];
using (FileStream fs = new FileStream(file, FileMode.Open))
{
fs.Read(buff, 0, maxContent);
} //using
int result = FindMimeFromData(IntPtr.Zero, file, buff, maxContent, null, 0, out mimeout, 0);
string mime = Marshal.PtrToStringUni(mimeout);
Marshal.FreeCoTaskMem(mimeout);
return mime;

I have been struggling with an issue that sounds like it should be quite common but I can't seem to get the thing working no matter how much I research it!
I am using an AJAX file uploader to upload files (up to 100MB) to the webserver and when the user clicks a button to complete navigate to the next page, I then attempt to move the files off the webserver onto a file server on Page_Load. Both servers are WinServer 2003. There just isn't enough space on the webserver to hold all the uploads once we go live with this solution so I have to get the files off the webserver.
Uploading the file and creating a new subdirectory on the webserver (to hold the file) works no problem at all. When I do the file copy to our file server locally on VS2008, again, no problem. However, when I delopy to the live server and try the same thing, the upload happens ok, but the file copy does not. I get an UnauthorizedAccessException. I don't have access to the webserver myself (but can request it if absolutely necessary) and our file server sits within the same domain (Active Directory).
I do not want to use Impersonation at a high level (web.config), so I tried it programmatically for the purposes of the copy file but it did not work. I used one of our general clerical accounts to pass in the credentials and gave full permission to this account on the file server to create/modify files.

in my case, It is the windows service which in running the long running insert/update on a table and I need to cancel the operation from my ASP.NET application. In the above link Burnsys suggests that one should kill the Sql server session. Is that really only way and a goood practice to do this? Also, in the same poset can use SqlCommand.Cancel to cancel. However, I am not sure how can I cancel the command from the windows service from ASP.NET application.

My code can be found here http://stackoverflow.com/questions/3604864/c-asp-net-ftp-error I am trying to download a file from an FTP server when I try to download it it says I do not have access I have been googling this all morning and have not had any luck. I went to the designated folder and added Everyone with full permissions hoping I was missing a user and that did not work. I tried giving full permissions to myself, Anonymous user, network service, and a few other users that I have found. I have tried using
<identity impersonate="true" /> and
<identity impersonate="true" userName="myfullusername" password="mypassword"/>
I am still not having any luck the full error I get is:

I am facing an error when requesting to WEBPageMethod using jquery and get 401 Unauthorized response and here is code for that
[code]....
I keep redirected to a "401 Unauthorized" page, which is the Login page. It first loads a 302 Found (Failed to load source for: http://localhost:4558) page then
the redirection.
<!--<authentication mode="Forms">
<forms loginUrl="~/Login" timeout="2880"/>
</authentication>-->
Everything works well when I comment the attribute Authentication at web.config or if after I logged-in.
Before this happens, I delete all files at (C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files). Don't you think this is the reason?
I'm under MVC, even if I remove the action filter Authorize(), I still get redirected to 401.

I use VWD 2008 SP1 and MSSQL2005.
I'm trying to connected to a third-party server, that allows API access via XML post/response. I've created just a very simple test page with a button to press.... the button should just go to the URL, log in with basic authentication and then return the response. if I use a browser and go to the URL, I see the XML response. Usuing my app, I'm still getting 401 unauthorized. I've been at this for hours, I've searched the forums and googled extensively, still no luck. Also, this is an internal app to internal server so security is not the highest priority. I'm setting the UN and PWD for authentication in a simple form.
Here's my VB code behind:
Dim request As HttpWebRequest
Dim response As HttpWebResponse = Nothing
Dim reader As StreamReader
Dim result As String
'disables self-signed SSL cert errors
[Code] ....
And the username and password are 100% accurate - as I mentioned above the code (well, implied).
I feel like this SHOULD be pretty easy: Overall request for testing: Submit a web request to a URL, disable the SSL check (self-signed certs used), login with basic UN and PWD I supply, return the response to a textbox.
