C# - Can Get WCF FaultException When Server Returns An HTTP 401
Jan 11, 2010
I 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?

I have a WCF client test harness where I'm using a "client message inspector" endpoint behavior to "pick off" raw requests and response messages going to and from a service and save them for later display in the UI.
This works great, except for the use case where invalid credentials are passed (Basic Authentication). The server returns an HTTP 401 along with a SOAP fault in the body containing details of what happened. I have no control over the service, so this behavior cannot be changed.
Because the HTTP 401 is returned as a WebException, my message inspector never fires and I can't get to the raw response. This exception eventually gets to the UI in the form a MessageSecurityException.
Is there any way to suppress this so the message inspector's AfterReceiveReply still fires? or is there somewhere else I can access the entire raw response?

I have created a web service that interacts with my DAL. It has the usual kind of methods, create, retrieve, update and delete. I have published this web service to our live Windows Server and I can see the web serice URL. The web service works on a few method calls but does not work specifically for one object. I am getting the following error: Fault Exception was unhandled by user code. "Server was unable to process request. ---> Data is Null. This method or property cannot be called on Null values."
To summarise: Web service is live, I can see it in my browser. Some method calls work. One specific one does not. I have verified that the method works (it is just calling a SQL stored proc that does return data).

I have a webservice (ASMX) which I have tested locally using built-in VS web server. It works fine in the Dev environment, and there was no configuration of anything in IIS for this kind of webservice to work.
Today when I deployed my site on the live server, I got a 500 error when the webservice is being called. The website doesn't work, and unfortunately the client did not test this on staging (same server)
Here's the sample call to my service.
$.ajax({
type: "POST",
url: 'http://www.mydomain.com/services/someservice.asmx/MyMethod',
data: "someid=564",
dataType: "xml",
success: function(msg){
}
In Firebug, http://www.mydomain.com/services/someservice.asmx/MyMethod returns error 500 internal server.
I called the service using jQuery AJAX, the live server is Windows Server 2008 Standard.

In my asp.net web site I have custom error pages defined as following in my web.config file.
<customErrors mode="On" defaultRedirect="~/defaulterror.htm" >
<error statusCode="404" redirect="~/404.htm" />
When file is not found it correctly display 404.htm page but the issue is when I do Fiddler trace it returns 302 as HTTP status code.This is a big issue for search engine page indexing due to this lot of broken links still have been indexed recently because of this in my web site. how can I prevent returning 302 as HTTP status code for file not found errors and return 404 for file not found errors.I am using asp.net 3.5.

I have a HTTP handler that returns a GeoRSS feed (type of XML) when called. This handler is called from a javascript and the returning xml is consumed directly by a Virtual Earth (bing) map control on the same page. I am Encrypting/Decrypting URL parameters but any one can see the source html, copy the url and get access to the xml feed.Since the call is from javascript how can I prevent unauthorized access to the HTTP handler?

I wrote a web services with Windows authentication, when i consume this WS from my app inside my network all work great, but when I consume this WS outside my network the WS return "The request failed with HTTP status 401: Unauthorized"I'd try the URL in an explorer page and all works great.In my app I use this:
webservice.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;
What alternatively can I use to get credential inside and outside of my net?

I have a webapplication based on MonoRail, where we utilize the routing feature from MonoRail. On the first request after the application has started, the routing isn't initialized. To circumvent this, I have the following code in Application_OnError():
public virtual void Application_OnError()
{
if ( // identified as routing error )
Server.TransferRequest( Context.Request.RawUrl, false );
return;
}
Problem beeing that on our development server (which runs server 2008 R2, with IIS 7.5 and .NET 3.5) returns a blank page without headers, but on my workstation (which runs win7, IIS 7.5 and .NET 3.5) it works fine.
What could be the cause of this? If the code in Application_OnError() throws an exception, what would be the expected output?
I have verified the following:
The access-log shows one entry, I'm not sure if a TransferRequest would show up as a second entry when invoked successfullyThe application actually do some work according to my internal logs, and it doesn't die since a subsequent requests works flawlessly (because routing will be active)

I have a Stored Proceedure which DID return the Scope_Identity when this was executed in SQLServer 2000.
Now I am porting this over to SQLServer 2008, and this always returns 0, and not the Scope_Identity which it should.
Here is the Stored Proceedure which will pass null for the parameter @pProjId for an insert:
[Code]....
Here is the script which creates the hip_Project Table:
[Code]....
What do I need to change for SQLServer 2008?
Again, this executed fine in SQLServer 2000 and always returned the Scope_Identity as expected. This problem has come up with other stored proceedures as well for which I need the Scope_Identity returned.

using ASP.NET 2.0 SqlDataAdapter update returns 0 records. I have a simple application that stores Passenger's ticket info in a sql database.
when a user clicks "Create Reservation" I add a Passenger Information (name, destination, PNR) to dataset
and save dataset in ViewState.
Then when user clicks update, I pull the dataset from viewState and try to update database. The update is returning 0. what i am doing incorrectly?
protected void btn_CreateReservation_Click(object sender, EventArgs e)
{
DataRow dr ;
dr = dt.NewRow();
dr["Name"] = txtBox_Name.Text; dr["Destination"] = txtBox_Destination.Text;
dr["PNR"] = Convert.ToInt32(txtbox_PNR.Text); dt.Rows.Add(dr);
dt.AcceptChanges();
ViewState["MyTable"] = dsPassengers;

I have a routine that submits a SOAP request using HttpWebRequest and WebResponse. If the SOAP Request fails the server sends back HTTP/1.1 500 Internal Server Error. When I trap the error I have yet to find a way to view the body of the reply which contains the fault code. Is there a way to retrieve the message body when the server returns a 500 internal Server Error? In body of the reply which I am not able to retrieve.
faultstring xml:lang="en-US" Specified argument was out of the range of valid values.

I have a table line (ID, LineNo, LineName) having values as :
1, 1, <blank>
2, 2, <blank>
3, 3, <blank>
ID is PK with Auto-Increment and LinNo(I am manually incrementing through ASP.Net Page while record insertion) Now i have to write a query such that it updates LineName column from line table which is blank(as shown above) with values from table linet(linenamet) having values as :
a
b
c
My trial query is :
update line set LineName = (select linenamet from linet);
It gives ERROR as : Subquery returns more than 1 row
Expected Result : After Updation it should show line table as :
1, 1, a
2, 2, b
3, 3, c

My ASP.NET MVC web app has a weird issue. In VS debugging mode it works as expected, but when I publish it to dedicated web server (windows 2003, IIS6) a sql query returns previous data even though underlying data was already updated through the same connection. It looks like as if a query returns cached data. What might be the problem?

I'm trying to mock Server.HtmlEncode(), but I keep having a null reference exception.I'm pretty new to the Moq framework, here is my code:
var context = new Mock<HttpContextBase>();
var request = new Mock<HttpRequestBase>();
var response = new Mock<HttpResponseBase>();
var session = new Mock<HttpSessionStateBase>();
var server = new Mock<HttpServerUtilityBase>();
server.Setup(svr => svr.HtmlEncode(It.IsAny<string>())).Returns((string s) => s);
context.Setup(ctx => ctx.Request).Returns(request.Object);
context.Setup(ctx => ctx.Response).Returns(response.Object);
context.Setup(ctx => ctx.Session).Returns(session.Object);
context.Setup(ctx => ctx.Server).Returns(server.Object);
I've also tried the following:
context.Setup(ctx => ctx.Server.HtmlEncode(It.IsAny<string>())).Returns((string s) => s);
I've found a solution but it seems an outdated solution as expect is replaced with setup.

I am running an Update statement against an SQL database on server 2008. The update runs but does not update the record, but returns no errors.The database is part of a commercial help desk package called TrackIt 8.5 which was just a fresh install on a new web server and a new sql server. The update is running from a web form we use to automatically create active directory accounts. After the account is created the web form closes out the work order in the Trackit db. This was working fine when the system was running on Server 2003 and SQL server 2005. Running Trackit version 7.02.The login use to access the database has full permissions to read and write to the database, just as it did on the old server which never had an issue updating. Odd thing is, if I log onto the SQL server and make a change to any single field in that record. I can then run the web form and it updates the record normally.

I have a web application in ASP.NET 4.0. I've added an asmx service, primarily as a source for the autocomplete extender's lookup values.
When I debug on my machine locally, everything works fine. However, when I deploy the web application to IIS 7.5, I get a HTTP 404 response when trying to send data to the service.
I am able to browse to the service definition, see the available operations. Tellingly, however, when I use the test pages to test the service using POST, I receive an HTTP 404 again.
I'm not sure what is going on. I did create the asmx file within my web application and it is deployed in the virtual directory of my otherwise working production application. Is there an issue with the .asmx file being deployed in the same virtual directory, perhaps?

I'm new to .net, and I've noticed that when viewing my HTML source code generated by a .net application the carriage returns are removed from the head tag when it has runat="server" attribute on it.
I remove the runat="server" and the returns... return.
This really looks nasty when you have a few javascript and css files in your header because it ends up making the entire contents of the head tag 1 big line.
Just wondering if there's a way to control this or tell .net through configuration not to mangle the output?

Using vs.net 2005 and sql server 2005.
Hope this makes sense: I need to create a stored procedure that I am going to use as a datasource for a crystal report in vs.net.
The issue is that the data is stored in 2 different kinds of databases, one is sql server and the other is plb files.
I have an odbc connections created for each separately however I need to make one query that joins data fields from both the sql server db tables and the plb db, how do I do this in one query that I will use in a stored procedure?

I have an ASP.NET page (using ASP.NET AJAX and the Telerik RAD components) that provides a data table and an option to download data in CSV format.I have a requirement that a single button allow the user to download a data set. I have a system set up that's nearly working for me based off the solution in
http://stackoverflow.com/questions/104601/asp-net-response-redirect-to-new-window
<asp:Button ID="ExportCsvButton" runat="server" Text="Download to CSV/Excel"
byte[] csvBytes = someLongOperation();
Session[EXPORTED_SESSION_KEY] = csvBytes;
Response.Redirect("myexportpage.aspx", true);
protected void Page_Load(object sender, EventArgs e)
{
Response.Clear();
Response.ClearHeaders();
Response.ClearContent();
Response.AppendHeader("content-disposition", "attachment; filename=" + "file.csv");
Response.ContentType = "text/csv";
Response.AddHeader("Pragma", "public");
Response.BinaryWrite(Session[OtherPage.EXPORTED_SESSION_KEY] as byte[]);
Response.Flush();
Response.End();
}
This actually works quite well. When I click the 'Export to CSV' button, the page's UpdateProgress kicks in and my loading overlay appears (it's a CSS div that covers the window when visible). This can take some time depending on the data set (potentially several minutes), at which point I'm getting a window popup with my file.
