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 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;
}

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.

In the above code, am facing a prob in skt.Available. If i dont give the thread.sleep, it is not repeating the while loop and it exits after onetime. And if i dont give skt.Available line, sometimes it throws socket Exception. I do not want to use thread.sleep. Does anyone knows why this is happening and how can i resolve this?

I have both VS 2005 and 2008 installed on my machine. 2005 is fine. For 2008, literally any asp.net project I try to create gets this eror. I try stepping into the code, and the error occurs apparently before anything that I can trap is loaded. There is no information written to the event log. I have tried this with a "Hello World" webpage with nothing else going on. Seems unique to my Windows Server 2003 machine.
View 3 Repliesin 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.
View 1 RepliesI'm about ready to deploy an MVC web application that I've been tasked with managing (I did not create the application). The project is now compiling in production mode with no errors, however I have some warnings - 9 to be precise.
Now 6 are to do with the test project which is fine, however there are two that involve the Web project. these errors are:
Unreachable code detected
In both instances these warnings are thrown on the Return value, e.g.
protected override ValidationResult IsValid(object value, ValidationContext validationContext)
{
if (true)
{
return new ValidationResult("Passwords don't match", new string[] { OriginalProperty });
}
return null;
}
In the above example, the "return null" line throws the unreachable code warning.
This might be a silly question (so please go easy ;-) ), but how important are these warnings to the functionality of the application? Obviously they are there for a reason, but they're not errors, so would I be relatively okay to ignore them and deploy?
I'm having a problem with downloading excel file created by server side. I keep getting the following error:
Could not complete the operation due to error c00ce514.
I'm getting the above error message in my C# code on my asp backend pages.
here is the line:
Chart1.Legends["Default"].FontColor = this.LegendFontColorPicker.Color == null ? Color.Black : this.LegendFontColorPicker.Color;
The error message occurs on every line that uses this ?: expression format, but MSDN says it's legit.
I am using static class to do every job related to Database. In this class Connection Object is static but i am creating command object in the method. I read a form post here [URL] about creating connection object local. If we do like that how can we use Connection pooling? There is an example code below.
I am creating a connection object with pooling (Validate Connection=True; Min Pool Size=10; Max Pool Size=200; Incr Pool Size=10; Decr Pool Size=5;). I am expecting to use connection pool by static connection object (this obje has a connection poll) with dynamicly created commands. Am I wrong? Sometimes i am getting "System.InvalidOperationException: Operation is not valid due to the current state of the object." error. Is it because static connectin object?

I have the following query:
Dim roommates = From p In dbroom.Residents _
Where p.room = queryStudent.First.r.id _
Where p.building = queryStudent.First.b.id _
Where p.year = year _
Where p.semester = term _
Select p.person_name
It currently returns no results. I was getting an error when attempting to bind this resultset (since it was empty) to a repeater in ASP.NET, so I attempted to escape it:
If roommates.Count() = 0 Then
Dim nomates As String = "No current roommates."
rptrRoommates.DataSource = nomates
rptrRoommates.DataBind()
Else
rptrRoommates.DataSource = roommates
rptrRoommates.DataBind()
End If
But I still get the same error:
The method 'First' can only be used as a final query operation. Consider using the method 'FirstOrDefault' in this instance instead.
guys, i have an application that uses Active Directory Authentication and deployed the application several days ago without any error. Today, I got this error.please refer to the image. I find it weird because I didn't change any code to my webconfig file since i deployed the application to the server. I've notice that it's working if it's [URL](by opening the source file in server and debug it) however when i try to access the application through [URL] I'm getting this error. I'm using 2.0 framework And here's my web.config
