Hi guys,

I've tried so many combinations, but I can't simply get the user name. What settings should I use in IIS and web.config to achieve this?

Basically I've created a simple web site that should sends an email, but the email address will be coming from the database based on the user's network login to that terminal server. Since I can't get the right value, I've simulated what is actually being extracted when the page loads. So in a test listbox I've added this:

ListBox1.Items.Add("Identity: " + HttpContext.Current.User.Identity);

ListBox1.Items.Add("Identity Name: " + HttpContext.Current.User.Identity.Name);

ListBox1.Items.Add("User Name: " + Environment.UserName);

ListBox1.Items.Add("Windows Identity name: " + System.Security.Principal.WindowsIdentity.GetCurrent().Name);

ListBox1.Items.Add("Page identity: "+ Page.User.Identity.Name);

AND THE OUTPUT I"M GETTTING...

 Identity Name: System.Security.Principal.WindowsIdentity

Identity Name: [empty string here]

User Name: IUSR

Windows Identity name: NT AUTHORITYIUSR

Page Identity: [empty string here]

Also, some of these work in my machine using local host, but when deployed in the intranet, those are the output. Any ideas please?

 Just want to add that my website's setting in IIS are: Allow all users under .Net Authorization rules; Anonymous Authentication and ASP.NET Impersonation are enabled under Authentication; In the file web.config, Authentication mode is "Windows".

ok i have no clue why i am getting this error.  i am simply trying to take some data entered into three different text boxes and upload it to a database once the submit button is clicked.  see below for my code sample and the error .  thank you in advance for any help you may be.  also if you see anything  i have wrong besides the error please let me know . 

thank you!

HI ,

I need to put 301 redirect in my web site. [Inner pages not the root domain]

Example: if someone hits http://wwww.testsite/AspNet/SDetails?id=3444

Redirect this to http://wwww.testsite/AspNet/SDetails?id=4000

Thank you.

Hi,

I built a Gridview and then added the Command Field to it, which has Edit, Delete, Select, and update functionalities.

When clicking on Edit link, textboxes open on the selected row to enable updating the row.  Users enter the text in the textbox and then click update to save it in the database.

I would like to add the ability for the users to add text and heyperlinks that will display as a hyperlink after its saved.  The way as it is now, the Gridview will only display it as a text after its saved.

Hope it is possible to do it ????

Thank you,

Hi all,

I am trying to run a basic auction website via VS2010 that I have downloaded from http://auctionsk.codeplex.com/

But cannot get it to run, recieving the error:

Line 26: </siteMap>

Line 27: <roleManager enabled="true"/>

Line 28: <compilation debug="true" targetFramework="4.0">

Line 29: <assemblies>

If I try to add a user via the Website/ASP.NET Configuration i get this:

An error was encountered. Please return to the previous page and try again. The following message may help in diagnosing the problem: Default Role Provider could not be found.

I have tried all sorts for the past few hours to resolve this, but to no luck!

Has anyone got any ideas?

Thanks

P.S. I am also unable to access the code behind! If I add a button and double click it I get "Could not complete the action"!  Is there a reason for this?

Hi All,

I have an application in which there will be urls like http://mywebsite.com/college.aspx?id=12 now i want this url to be http://mywebsite.com/college/12 what is the easiest way to do it.

Note: I am using request.QueryString to read the college ID and display the data. Will this work after the URL rewrite? If not how should I get the querystring value?

Any help will be greatly appreciated!!!

Thanks in advance, Ram

This is posted here because it might be module related. MVC 3+, Win7 (development)  (IIS7 production)

Using VS2010 Local server my HttpModule for exception handling works fine.  When going to IIS I get the yellow screen of death.

The example below is for MVC, but an extremely similar Module which worked for years for Asp.net applications is now failing the same way.  It differed by instead of returning a view, returned an embedded aspx page.

So I tried messing with the web.config by using httpErrors and I tried messing with the response by adding: TrySkipIisCustomErrors

But nothing is working.

Hey All,

I have some JSON that is dynamic, in that I don't know exactly what will be included, but need a way deserialize and parse the data. I have been using JSON.net up until now, but am really at a loss on how to do this as most examples I find have static JSON. I'm open to any method or technology that would make it easier.

I need to parse the JSON from C# and not Javascript.

Any thoughts or pointers to examples?

Thanks Jay

Shown Below are stored procedure and code. As a test example I want to plot utilization vs Month in a

hey, im working on a project and decided to start with the html layout first

i was wondering how can i make a clickable elements such as divs or even li insted of

using the <input> tags for example the menu here (asp.net) at the forums when a mouse hover is trigerd a sub menu

appears, 

another question -  take facebook header, when you click the tiny message icon a sub menu shows up

is that a javascript / jquery ? im not talking about the data that's obviously ajax, im talking about the html itself  

I have a really strange situation.  I have a single Model, and two templates that are both strong-typed on the type of this model.  The templates are nested, or in other words, I use DisplayFor on the second Template from within the first template.  If I use the model associated with the first template, in the DisplayFor call for the second template, the second template does not render.  If I use another instance of the same model type, everything works fine.  It seems like there is some sort of cycle checking on the models associated with nested templates.  

Model:

public class MyModel
    {
        public string Value { get; set; }
        public MyModel Copy
        {
            get { return (MyModel) this.MemberwiseClone(); }
        }

        public MyModel MySelf
        {
            get { return this; }
        }
    }

DisplayTemplate 1:

@model TestNestedTemplateSameReference.Models.MyModel

<div>Model1</div>
<div>@Model.Value</div>
<div>@Html.DisplayFor(x=>x, "ModelTemplate2")</div>

DisplayTemplate 2:

@model TestNestedTemplateSameReference.Models.MyModel

<div>Model2</div> <div>@Model.Value</div>

Interestingly if instead of calling 

@Html.DisplayFor(x=>x, "ModelTemplate2")

I call it with the Copy property

<div>@Html.DisplayFor(x=>x.Copy, "ModelTemplate2")</div>

everything works fine as the actual instance of the MyModel class is different.

Does anyone know why this is done.  Is there a viable workaround.  It seems like this is a perfectly legitimate usage which shouldnot cause a stack overflow, or any similar issues.  I could see how this could be used to protect against cycles for DisplayFor call without template name, but if I specify the template name seems like it should work fine.  

It seems like it would be dangerous to bind the same model to multiple EditFor templates, but DisplayFor seems safe.

I can of course create a separate model for nesting level, but that is creating redundand class.

Any help is appreciated.

I want the control to initially display a rating based on the average rating given so far.  Say customers are fairly happy with an item and have given it an average of 4 out of 5 stars.  The current user really likes the item, and rates it 5 stars.  So far so good, the 5 start rating is recognized and added to the database.

But what if the current user also thought the item deserved 4 out of 5 stars?  Because the control uses a OnChanged event, the current user is not able to rate the product.  The average rating is 4, and the user rates the item a 4, there is no change to trigger the OnChange event.

I would think this is a common use for the control, how is this handled?

I am looking to create this custom user control.  Know to create the custom control, but what I am having a hard time with is publishing it into a DLL so that I have distribute my other applications.

Can someone point me in the right direction?

Thanks in advance,

I am trying to send an email...it works fine on the development server but not on the production server.  I get the error "The SMTP host was not specified. " on the production server.  When I add the settings to the web.config file it doesn't work on the development or the production.  I get the error "Client doesn't have permissions..."  Any ideas?   Thx. 

I have the following in my web.config file:

  <system.net>

    <mailSettings>

      <smtp from="">

        <network defaultCredentials="false" host="" password="" userName="" />

      </smtp>

    </mailSettings>

  </system.net>

I'm trying to use the MaskedEditExtender and CalendarExtendar from the Toolkit.

I am having an issue when you type a date in the TextBox after the first time, it is not focusing to that date when you open the Calendar. It does not work in IE9. It does work in IE9+compatability mode. I can reproduce this on the Toolkit Demo site as well.

Steps to reproduce:

1. In IE9 (non-compatibility mode)
2. Go to http://www.asp.net/ajaxLibrary/AjaxControlToolkitSampleSite/MaskedEdit/MaskedEdit.aspx
3. In the 3rd field, type 12/12/2012
4. Click the Calendar icon
5. 12/12/2012 is selected in the Calendar
6. Now change your date text to 12/12/2010
7. Click the Calendar icon
8. 12/12/2012 is still selected in the Calendar
9. Repeat the steps in compatibility mode
10. In step 8, 12/12/2010 will be selected as expected

Anyone else have this issue? If so, has anyone found a work-around?

I'm receive it from a web service with the code that follows:

private void fillTextBox()
        {
            XNamespace te = "http://schemas.datacontract.org/2004/07/TesteWebService.Model";
            using (HttpClient client = new HttpClient("http://localhost:8080/teste/"))
            {
                using (HttpResponseMessage response = client.Get("games"))
                {
                    response.EnsureStatusIsSuccessful();
                    
                    XElement elementos = response.Content.ReadAsXElement();
                    lista.Text = "";


                    StringBuilder t= new StringBuilder();
                    var names = elementos.Descendants(te +"name").Select(element => element.Value);
                    foreach (string s in names)
                    {
                        t.AppendLine(s);
                    }
                    lista.Text= t.ToString();

                }
            }

That code just get the names, but a want to get the id, name and genre. Thank you for any help
