Website Returns 302 Instead Of 200?

So, am i missing something here? I have not placed any redirect in any way.
So where the f#$% my website redirects? Is there a security hole?

C# - WCF Service Returns 400 Bad Request
Mar 18, 2011I've got this application that works locally and when deployed and using a .mdf SQL Express database file (which I usually use for testing purposes). However, when I change it to work with our SQL Server 2008 the app works but the service doesn't. For example if in my code behind of a page I have a button that adds data to a table such as this it works fine:
public static string connString = @"Data Source=server1;Initial Catalog=Project;Integrated Security=True";
protected void btnAddProj_Click(object sender, EventArgs e)
{
using (var sqlc = new SqlConnection(connString))
{
sqlc.Open();
var cmd = sqlc.CreateCommand();
int intProjectID;
// Add the project info to the database
cmd.CommandText = "INSERT INTO tblProject VALUES(@ProjName,@ProjTeam,@ProjStart,@ProjEnd)";
cmd.Parameters.Add("ProjName", System.Data.SqlDbType.NVarChar).Value = txtProjName.Text;
cmd.Parameters.Add("ProjTeam", System.Data.SqlDbType.Int).Value = ddlTeamSupported.SelectedValue;
cmd.Parameters.Add("ProjStart", System.Data.SqlDbType.NVarChar).Value = txtStartDate.Text;
cmd.Parameters.Add("ProjEnd", System.Data.SqlDbType.NVarChar).Value = txtEndDate.Text;
cmd.ExecuteNonQuery();
}
}
My web.config is setup to use impersonation on that server and all works perfectly well. However, for my service the query doesn't seem to return anything and I get a 400 Bad Request error. The code for the jquery is:
$.ajax({
type: "POST",
async: false,
url: "Services/ProjectService.svc/test",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (data) {
console.log(data);
}
});
And for the Service:
[ServiceContract]
public interface IProjectService
{
[OperationContract]
[WebInvoke(ResponseFormat = WebMessageFormat.Json)]
ArrayList test();
}
public static string connString = @"Data Source=server1;Initial Catalog=Project;Integrated Security=True";
public ArrayList test()
{
var sqlc = new SqlConnection(connString);
sqlc.Open();
var cmd = sqlc.CreateCommand();
cmd.CommandText = "SELECT ProjectID FROM tblProject";
var reader = cmd.ExecuteReader();
ArrayList temparray = new ArrayList();
while (reader.Read())
{
temparray.Add(reader[0]);
}
sqlc.Close();
return temparray;
}
If instead of querying the database I have the service just return static data then it works fine. What could cause my service not to be able to connect to the database when the rest of the code behind for the app works?

C# - SelectionList Always Returns NULL - How To Fix It
Jul 20, 2010I have a very strange issue where SelectionList always returns NULL when i try check its Selected Item/Value. I Googled a bit and I found out that when i click the submit button, the page is being refreshed and the SelectionList is being data bound again so it will revert back to its original behavior.
Then i tried enclosing the binding code in the Page_Load event in a !IsPostBack but still when i try to access the Selected property it is null and an exception is thrown.
My code goes something like this... (the braces are not matched properly)
static SelectionList[] Symptoms;
static string UserID = "";
cmbSymptoms1,cmbSymptoms2,cmbSymptoms3 and cmbSymptoms4 are SelectionLists. I took them in to an array of SelectionList and then set the properties.
I had to make them static or else when i click the button to update, they will not retain their values.
protected void Page_Load(object sender, EventArgs e)
{
if (this.IsPostBack == false)
{
//System.Diagnostics.Debug.WriteLine("Not IsPostBack");
if (Request.QueryString["id"] != null && Request.QueryString.ToString() != "")
{
//System.Diagnostics.Debug.WriteLine("id query string is not null :- " + Request.QueryString["id"]);

View 3 RepliesArray Returns 0 Instead Of Assigned Value?
Aug 18, 2010I assigned a int value to to one of the cells in an array and then output that value to a label. The label correctly displays that value however when I try to get that value later in a different method the cell returns a 0. I think that the problem is that I shouldn't of made the array on the outside of a method; I checked the code that deals with the array about 3 times and it all seems fine. how I should create, get, and set this array. I was setting the value of the cell like this
arrayForXps[0,1] =Convert.ToInt32(ddl_att_desLvl.SelectedValue); //This value is never zero.
I was getting the value like this Label.Text = Convert.ToString(arrayForXps[0,1]);

C# - 'Contains' Method Returns False?
Jan 16, 2011I've an EntityCollection< T > which contains an element but the Contains method returns false.
I've overriden T's 'Equals' method but the 'Contains' method does not call it (while it's said so in documentation).
When I do foreach (T x in coll), x.Equals(element) returns true.
code:
contains(object entCol, object val)
{
var coll = (ICollection<GraphicSockets>)entCol;
var socket = val as GraphicSockets;
foreach (GraphicSockets sock in coll)
socket.Equals(sock); //true for first element, GraphicSocket's Equals function called
coll.Contains(socket);//false, Equals function not called}
the code i'd actually like to use is
private static bool contains(object entCol, object val)
{
Type entColType = typeof(EntityCollection<>).MakeGenericType(val.GetType());
MethodInfo contains = entColType.GetMethod("Contains");
return (bool)contains.Invoke(entCol, new object[] { val });
}
this worked once but stopped when i started using wcf, i wonder how this contains method works.....

MVC :: Typing A URL Some How Returns /Home?
Mar 5, 2011I have a weird problem with my MVC application.In my _Layout.cshtml file I have created 3 menu links and each points to a location. On my personal PC clicking each link will browse to the specifc page without any issues. However, when I deployed my app to a hosting website. The first 2 links work fine but the 3rd one returns me to ~/Home
Using IE developer tools here is the network capture:
Request: GET /myapp/mylink HTTP/1.1
Accept: imaged/jped etc..
Refer: /myapp/home
The response is as follow:
Response: HTTP/1.1 302 Found
Location: /myapp/home
I am not really sure why am I getting a HTTP 302 and causing a redirect to /myapp/home.
Asp.net - Dataset Column Always Returns -1?
Aug 20, 2010I have a SQL stored proc that returns a dataset to ASP.NET v3.5 dataset. One of the columns in the dataset is called Attend and is a nullable bit column in the SQL table. The SELECT for that column is this:
CASE WHEN Attend IS NULL THEN -1 ELSE Attend END AS Attend
When I execute the SP in Query Analyzer the row values are returned as they should be - the value for Attend is -1 is some rows, 0 in others, and 1 in others. However, when I debug the C# code and examine the dataset, the Attend column always contains -1.
If I SELECT any other columns or constant values for Attend the results are always correct. It is only the above SELECT of the bit field that is behaving strangely. I suspect it has something to do with the type being bit that is causing this. So to test this I instead selected "CONVERT(int, Attend)" but the behavior is the same.
I have tried using ExecuteDataset to retrieve the data and I have also created a .NET Dataset schema with TableAdapter and DataTable.

View 16 RepliesVS 2010 - Returns A Comma Instead Of ID
Aug 5, 2014My problem is that all of a sudden the __EVENTTARGET isn't working. It returns a comma for some controls (that arent given that ID of coure). At first I didn't have the energy to investigate this, I just made sure the comma was handled. But that was before I needed another control (asp:button) to behave in a certain way. Now the button returns a comma as ID, which triggers an event that I don't want for the button_click.

so when I am trying to use ID in other functions it falls back to zero

MVC :: Static Content Returns A 500 Error?
Nov 16, 2010I think I might be missing something obvious but I'm not sure. The other day I was trying to run throught the windows live ID domain verification process on my asp.net mvc site. Part of the process requires you to download a text file and put it in the root of your site which your domain points to. When I would click the verify button in the windows live app verification process it would fail. In a browser, I could hit the request the text file and get a 200, which puzzle me. I then used this site http://www.internetofficer.com/seo-tool/redirect-check/ to check for any redirection issues. Suprisingly when I enter in the url to check, in my case http://www.whatitcoststobeme.com/741KXPjf42zgZRnV6O1LsO92.txt, it returns a 500 error. I ran this same test against a non-MVC site and the verificaton process passed plus the redirection checker return a 200 ("direct link" on their site). The environment this was tested in was IIS7.
why this is happening with static content on a ASP.NET MVC site? I want to say it's something to do with the url routing handlers.
C# - The IndexOf() Method Returns -1 All The Time
Aug 26, 2010i have two data tables with the same structure
the first one has one row of the second one
the second one has set of rows
what i want is to get the row which comes next to the row of the first data table in the second data table.
the first data table his name is :: temp
the second data table his name is :: dt
i do the following:
DataTable temp = new DataTable();
temp = dt.Clone();
DataColumn[] keyColumn = new DataColumn[1];
keyColumn[0] = temp.Columns["photoId"];
temp.PrimaryKey = keyColumn;
temp = (DataTable)(Session["currentImage"]);
DataRow[] drr = new DataRow[1];
index = dt.Rows.IndexOf(temp.Rows[0]);
but the index always comes with one value = -1
although the temp.rows[0] its contents changed all the time
when i write dt.Rows.IndexOf(dt.Rows[1]) for examble i get 1
but this is not what i want to do ,, what i want to do exactly is to get the datarow next to the datarow of the first dataTable in the second dataTable
Mvc Json - Color Always Returns Null
May 22, 2010I am working on a mvc project, and having problem with json. i have created a demo project with list of colors
public JsonResult GetResult()

ADO.NET :: SP From Linq Returns Empty Or Null Value
Feb 15, 2011I have a class library which has my LINQ doc in it. I added a stored procedure and I get the following in my .dbml.layout :
[Code]....
I include a reference to the dll of the class library to my web project and I get an error about value being returned as int where I am trying to put contents into a datalist or similar.
Code in class that calls this SP :
[Code]....
So I switched code to the following in my dbml.layout document :
[Function(Name="dbo.sp_newsSearch")]public IEnumerable<news_search_result> sp_newsSearch([Parameter(DbType="VarChar(200)")] string searchVal){IExecuteResult result = this.ExecuteMethodCall(this, ((MethodInfo)(MethodInfo.GetCurrentMethod())), searchVal);return ((IEnumerable<news_search_result>)(result.ReturnValue));}
And included the following in an external file news_search_result.cs
[Code]....
But now I just get nothing returned. Is this wrong way of calling a SP via LINQ? or have I just put the wrong return type on my LINQ class?
C# - Can Get WCF FaultException When Server Returns An HTTP 401
Jan 11, 2010I have a WCF based test harness client for a set of web services. The test client allows me to see raw requests and responses going to and from the services. A Message Inspector endpoint behavior is used to "pick off" the raw requests and response messages and save them for later display in the UI.
This works great, except for the use case where invalid credentials are passed. The server returns an HTTP 401 along with a SOAP fault containing details of what happened. This hurts me in a couple ways:
On the client this shows up as a MessageSecurityException not a FaultException, so I can't get the details from the fault. This exception appears to prevent the AfterReceiveReply event handler on my message inspector from firing, so I have no access to the raw response.
Is there any way I can handle this case so that the SOAP fault comes through as a FaultException and allow my message inspector to handle responses regardless of the HTTP status code that is returned?
Validation - Recaptcha Asp.net Always Returns Invalid?

I'm using localhost as the site but am not getting any public/private key errors which I did get when adding a bad key (as a test).I've seen this error reported a lot but no good answers. Some suggest to call the validate on the control before checking to see if it is valid but this did not work for me.
View 2 RepliesMVC :: RegularExpressionAttribute Validator Always Returns False?
Nov 17, 2010I'm using a model which receives some input from a form and has some validation logic attached via attributes. In one case I'm validating personal names, which should include only letters, apostrophes, spaces and dashes, and be no more than 50 chars long. So I have a model property like:
[Code]....
Everything works fine BUT the RegularExpression attribute: if I add it, I always get a validation error, even when what I type in my form is a valid name (e.g. "Foo"). No matter how I modify the regular expression or what I type, I always get an invalid name error.
(For some reason, I cannot see the regex posted correctly here: it is just ^ followed by the Unicode Letter class and []+ including a Unicode letter class, apostrophe, whitespace and dash, ended by dollar: i.e. start of string - any letter - any of the following: letter, apostrophe, whitespace, dash, 1 or more times; end of string).
