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;
}
#endregion
Locally, it runs fine. However, when I put it on a GoDaddy server, I get the error:
"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. "
My stracktrace points to line 256, which is the ending french bracket of my GetMimiFromFile function.

A socket operation was attempted to an unreachable host 208.101.14.59:80
I tried the same url by pasting it on address bar and works fine. When I call my vendor they r saying that there is no any problem from their side. Someone has suggested me that there may be some settings in web.config.

I am getting an exception that child actions are not allowed to perform redirect actions. Although I can understand that this might is true in most situations I do believe that the framework might allow this to pass when a Child Action is calling another child action like in this example:
I have this code in my CountryController (I compacted it a bit but the main concept remains that I have a controller with Child Actions only):
[Code]....
This exception is being thrown:
Server Error in '/' Application.
Child actions are not allowed to perform redirect actions. Description:An unhandled exception occurred during the execution of the current web request. Review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.InvalidOperationException: Child actions are not allowed to perform redirect actions.

I am working on a government site and am having some problems with my local security policy interferring with my web application. There is a setting called "System cryptography: Use FIPS 140 compliant cryptographic algorithms, including encryption, hashing and signing algorithms" which is enabled on my server.
Since that has been enabled, most of my aspx pages are returning the error "This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms." These pages aren't accessing any cryptographic methods. They do communicate with another database server, but that's it.
My problem is similar to the one described here. However, I don't have the option of disabling this FIPS security setting.
I am using .NET 4.0, IIS 7.0, and Windows Server 2008 R2, if that matters. Has anyone encountered this problem before?
Update
Unfortunately, correcting the machine key element to use a FIPS compliant algorithm did not completely solve my problem. I am still getting the error on alot of my pages.
I found two hotfixes which may be related. I will try to install these and see what happens.
SQL Server Reporting Services R2 hotfix ScriptManager Control hotfix

I'm working on a SharePoint solution which makes use of a third party dll (Telerik for Asp.Net Ajax - Telerik.Web.UI.dll) for rich experience. Since Telerik dll is a common assembly i have to deploy it to the bin folder of the webapplication instead of GAC. So here comes the problem.
WSPBuilder automatically deploys the dll to gac if the dll presents in the GAC folder. To deploy the telerik dll in bin i created the folder 80in and copied the dll there. I tried to build the wsp again and then went through the manifest.xml created. Great. The deployment target for the dll changed to WebApplication and wspbuilder was smart to create the cas policy itself.
<CodeAccessSecurity>
<PolicyItem>
<PermissionSet class="NamedPermissionSet" version="1" Description="WSPBuilder generated
[code]....
But Wspbuilder was not smart enough to put the four part name of SharePointPermission IPermission class. But i learnt that CAS actually requires the four part name. So i decided to make use of the -CustomCAS command line option of wspbuilder.exe to pass my custom cas policy file.
Here is my custom policy file -
<IPermission class="AspNetHostingPermission" version="1" Level="Minimal" />
<IPermission class="System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Flags="Execute" />[code]....
After i deployed the wsp i verified
* the dlls going to bin
* the trust level changed to custom trust level
* custom policy file being added to config folder
But when i run the page i get the following error -
screen shot -
Error -Execution Permission Denied
I've checked my entire application for any assembly references of the dll. But i was not able to find one.

If you enable the "Use FIPS compliant algorithms for encryption, hashing, and signing" security policy option in Windows, attempting to use many of the cryptographic classes in the .NET Framework will result in an InvalidOperationException. By default, ASP.NET uses AES to encrypt the ViewState blob, so it fails. You can work around this by adding a key like this to web.config:
<machineKey validationKey="AutoGenerate,IsolateApps" decryptionKey="AutoGenerate,IsolateApps" validation="3DES" decryption="3DES"/>
And that covers you for basic ASP.NET use. My problem is this: I have a large, complex ASP.NET web applications that makes heavy use of ScriptManagers (the foundation of ASP.NET AJAX) and needs to be deployed by a government customer who must enable this FIPS policy setting. Any ASP.NET page with a ScriptManager on it throws this exception:
[InvalidOperationException: This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms.]

Even adding the <enforceFIPSPolicy enabled="false"/> element to web.config does not resolve the exception.
Is there any way to configure ASP.NET such that ScriptManager can be used with the Windows FIPS security policy?

These types of exceptions always irritate me because they are almost impossible to reproduce consistently and have almost no documentation other than the cryptic error itself to have any idea on how to fix the problem. So I have a Windows Service that makes a call to a .asmx web service over https on a polled interval every 20 minutes. Once in a great while the following exception message is returned:
Message: The underlying connection was closed: An unexpected error occurred on a receive.
Inner Message: System.IO.IOException: The decryption operation failed, see inner exception. ---> System.ComponentModel.Win32Exception:
The specified data could not be decrypted --- End of inner exception stack trace --- at
System.Net.Security._SslStream.ProcessReadErrorCode(SecurityStatus
errorCode, Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest, Byte[] extraBuffer) at System.Net.Security._SslStream.ProcessFrameBody(Int32 readBytes, Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at
System.Net.Security._SslStream.StartFrameBody(Int32 readBytes, Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security._SslStream.StartFrameHeader(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest)
at System.Net.Security._SslStream.StartReading(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security._SslStream.ProcessRead(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.TlsStream.Read(Byte[]
buffer, Int32 offset, Int32 size) at System.Net.PooledStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Net.Connection.SyncRead(HttpWebRequest request, Boolean userRetrievedStream, Boolean probeRead)
So from reading the above message there was an error on receive and the data could not be decrypted. The does not occur consistently, so I don't have a good way of reproducing it. I also lack at low level messaging knowledge and I feel that this is the answer behind this exception; i.e. dropped packets and an incomplete message not appearing to be the same message as sent from the service or something. Any .asmx gurus out there that can give insight and possibly prevention suggestions for the above issue?

I ahev seen many discussion related to this , but I could not find proper answer , I have live web site set up on IIS 6, and set virtual path MYSite and then phisical path to the web.config file on actual location.
I have copy this site to another server for the purpose of further development, so I need to run production site exactly same as live site , i can do edit in production and update pages to live.
Once I have copied the site give this error virtual path '/includes/menu.htm' maps to another application, which is not allowed
i have master page include menu as html files <!--#include file="../includes/topmenu.htm"-->
I have open site in IIS 7 and add virtual directory and gave a name (not same as live) and choose physical path to the root folder of the site. In IIS 7 I cannot give web.config file for the path, it should be folder. and I have change identity in apppool to Network Service and gave readaccess permission to folder.
