• Windows 7: how to let AutoConfigURL change be effective immediately?

  - by Jeroen Pluimers

  I want to set both the script and the "Use automatic configuration script" checkbox in Windows 7 using a script that immediately affects anything using wininet.dll (Internet Explorer, Chrome, .NET apps, etc). I've done a before/after registry diff, and tried doing this through the registry, but things like the reg files below require the apps to be restarted. Chaning the settings by pressing the "LAN Settings" button through this Control panel shortcut has immediate affect: %windir%\system32\control.exe Inetcpl.cpl,,4 How can I script this immediate effect? These are the registry script files: [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings] “AutoConfigURL”=”http://www.company.com/proxy.pac” (registry scripts borrowed from http://danny.quantumspark.net/wordpress/) [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings] “AutoConfigURL”=- --jeroen (who is checking out the notify function at superuser.com)

• Remove Office 2010 Beta and Reinstall Office 2007

  - by Matthew Guay

  Have you tried out the Office 2010 beta, but want to go back to Office 2007?  Here’s a step-by-step tutorial on how to remove your Office 2010 beta and reinstall your Office 2007. The Office 2010 beta will expire on October 31, 2010, at which time you may see a dialog like the one below.  At that time, you will need to either upgrade to the final release of Office 2010, or reinstall your previous version of Office. Our computer was running the Office 2010 Home and Business Click to Run beta, and after uninstalling it we reinstalled Office 2007 Home and Student.  This was a Windows Vista computer, but the process will be exactly the same on Windows XP, Vista, or Windows 7.  Additionally, the process to reinstall Office 2007 will be exactly the same regardless of the edition of Office 2007 you’re using. However, please note that if you are running a different edition of Office 2010, especially the 64 bit version, the process may be slightly different.  We will cover this scenario in another article. Remove Office 2010 Click to Run Beta: To remove Office 2010 Click to Run Beta, open Control Panel and select Uninstall a Program. If your computer is running Windows 7, enter “Uninstall a program” in your Start menu search. Scroll down, select “Microsoft Office Click-to-Run 2010 (Beta)”, and click the Uninstall button on the toolbar.  Note that there will be two entries for Office, so make sure to select the “Click-to-Run” entry. This will automatically remove all of Office 2010 and its components.  Click Yes to confirm you want to remove it. Office 2010 beta uninstalled fairly quickly, and a reboot will be required.  Once your computer is rebooted, Office 2010 will be entirely removed. Reinstall Office 2007 Now, you’re to the easy part.  Simply insert your Office 2007 CD, and it should automatically startup the setup.  If not, open Computer and double-click on your CD drive.   Now, double-click on setup.exe to start the installation. Enter your product key, and click Continue…   Click Install Now, or click Customize if you want to change the default installation settings. Wait while Office 2007 installs…it takes around 15 to 20 minutes in our experience.  Once it’s finished  close the installer. Now, open one of the Office applications.  A popup will open asking you to activate Office.  Make sure you’re connected to the internet, and click next; otherwise, you can select to activate over the phone if you do not have internet access. This should only take a minute, and Office 2007 will be activated and ready to run. Everything should work just as it did before you installed Office 2010.  Enjoy! Office Updates Make sure to install the latest updates for Office 2007, as these are not included in your disk.  Check Windows Update (search for Windows Update in the Start menu search), and install all of the available updates for Office 2007, including Service Pack 2. Conclusion This is a great way to keep using Office even if you don’t decide to purchase Office 2010 after it is released.  Additionally, if you’re were using another version of Office, such as Office 2003, then reinstall it as normal after following the steps to remove Office 2010.

• Using a WPF ListView as a DataGrid

  - by psheriff

  Many people like to view data in a grid format of rows and columns. WPF did not come with a data grid control that automatically creates rows and columns for you based on the object you pass it. However, the WPF Toolkit can be downloaded from CodePlex.com that does contain a DataGrid control. This DataGrid gives you the ability to pass it a DataTable or a Collection class and it will automatically figure out the columns or properties and create all the columns for you and display the data.The DataGrid control also supports editing and many other features that you might not always need. This means that the DataGrid does take a little more time to render the data. If you want to just display data (see Figure 1) in a grid format, then a ListView works quite well for this task. Of course, you will need to create the columns for the ListView, but with just a little generic code, you can create the columns on the fly just like the WPF Toolkit’s DataGrid. Figure 1: A List of Data using a ListView A Simple ListView ControlThe XAML below is what you would use to create the ListView shown in Figure 1. However, the problem with using XAML is you have to pre-define the columns. You cannot re-use this ListView except for “Product” data. <ListView x:Name="lstData"          ItemsSource="{Binding}">  <ListView.View>    <GridView>      <GridViewColumn Header="Product ID"                      Width="Auto"               DisplayMemberBinding="{Binding Path=ProductId}" />      <GridViewColumn Header="Product Name"                      Width="Auto"               DisplayMemberBinding="{Binding Path=ProductName}" />      <GridViewColumn Header="Price"                      Width="Auto"               DisplayMemberBinding="{Binding Path=Price}" />    </GridView>  </ListView.View></ListView> So, instead of creating the GridViewColumn’s in XAML, let’s learn to create them in code to create any amount of columns in a ListView. Create GridViewColumn’s From Data TableTo display multiple columns in a ListView control you need to set its View property to a GridView collection object. You add GridViewColumn objects to the GridView collection and assign the GridView to the View property. Each GridViewColumn object needs to be bound to a column or property name of the object that the ListView will be bound to. An ADO.NET DataTable object contains a collection of columns, and these columns have a ColumnName property which you use to bind to the GridViewColumn objects. Listing 1 shows a sample of reading and XML file into a DataSet object. After reading the data a GridView object is created. You can then loop through the DataTable columns collection and create a GridViewColumn object for each column in the DataTable. Notice the DisplayMemberBinding property is set to a new Binding to the ColumnName in the DataTable. C#private void FirstSample(){  // Read the data  DataSet ds = new DataSet();  ds.ReadXml(GetCurrentDirectory() + @"\Xml\Product.xml");    // Create the GridView  GridView gv = new GridView();   // Create the GridView Columns  foreach (DataColumn item in ds.Tables[0].Columns)  {    GridViewColumn gvc = new GridViewColumn();    gvc.DisplayMemberBinding = new Binding(item.ColumnName);    gvc.Header = item.ColumnName;    gvc.Width = Double.NaN;    gv.Columns.Add(gvc);  }   // Setup the GridView Columns  lstData.View = gv;  // Display the Data  lstData.DataContext = ds.Tables[0];} VB.NETPrivate Sub FirstSample()  ' Read the data  Dim ds As New DataSet()  ds.ReadXml(GetCurrentDirectory() & "\Xml\Product.xml")   ' Create the GridView  Dim gv As New GridView()   ' Create the GridView Columns  For Each item As DataColumn In ds.Tables(0).Columns    Dim gvc As New GridViewColumn()    gvc.DisplayMemberBinding = New Binding(item.ColumnName)    gvc.Header = item.ColumnName    gvc.Width = [Double].NaN    gv.Columns.Add(gvc)  Next   ' Setup the GridView Columns  lstData.View = gv  ' Display the Data  lstData.DataContext = ds.Tables(0)End SubListing 1: Loop through the DataTable columns collection to create GridViewColumn objects A Generic Method for Creating a GridViewInstead of having to write the code shown in Listing 1 for each ListView you wish to create, you can create a generic method that given any DataTable will return a GridView column collection. Listing 2 shows how you can simplify the code in Listing 1 by setting up a class called WPFListViewCommon and create a method called CreateGridViewColumns that returns your GridView. C#private void DataTableSample(){  // Read the data  DataSet ds = new DataSet();  ds.ReadXml(GetCurrentDirectory() + @"\Xml\Product.xml");   // Setup the GridView Columns  lstData.View =      WPFListViewCommon.CreateGridViewColumns(ds.Tables[0]);  lstData.DataContext = ds.Tables[0];} VB.NETPrivate Sub DataTableSample()  ' Read the data  Dim ds As New DataSet()  ds.ReadXml(GetCurrentDirectory() & "\Xml\Product.xml")   ' Setup the GridView Columns  lstData.View = _      WPFListViewCommon.CreateGridViewColumns(ds.Tables(0))  lstData.DataContext = ds.Tables(0)End SubListing 2: Call a generic method to create GridViewColumns. The CreateGridViewColumns MethodThe CreateGridViewColumns method will take a DataTable as a parameter and create a GridView object with a GridViewColumn object in its collection for each column in your DataTable. C#public static GridView CreateGridViewColumns(DataTable dt){  // Create the GridView  GridView gv = new GridView();  gv.AllowsColumnReorder = true;   // Create the GridView Columns  foreach (DataColumn item in dt.Columns)  {    GridViewColumn gvc = new GridViewColumn();    gvc.DisplayMemberBinding = new Binding(item.ColumnName);    gvc.Header = item.ColumnName;    gvc.Width = Double.NaN;    gv.Columns.Add(gvc);  }   return gv;} VB.NETPublic Shared Function CreateGridViewColumns _  (ByVal dt As DataTable) As GridView  ' Create the GridView  Dim gv As New GridView()  gv.AllowsColumnReorder = True   ' Create the GridView Columns  For Each item As DataColumn In dt.Columns    Dim gvc As New GridViewColumn()    gvc.DisplayMemberBinding = New Binding(item.ColumnName)    gvc.Header = item.ColumnName    gvc.Width = [Double].NaN    gv.Columns.Add(gvc)  Next   Return gvEnd FunctionListing 3: The CreateGridViewColumns method takes a DataTable and creates GridViewColumn objects in a GridView. By separating this method out into a class you can call this method anytime you want to create a ListView with a collection of columns from a DataTable. SummaryIn this blog you learned how to create a ListView that acts like a DataGrid. You are able to use a DataTable as both the source of the data, and for creating the columns for the ListView. In the next blog entry you will learn how to use the same technique, but for Collection classes. NOTE: You can download the complete sample code (in both VB and C#) at my website. http://www.pdsa.com/downloads. Choose Tips & Tricks, then "WPF ListView as a DataGrid" from the drop-down.

• How to Assign a Static IP Address in XP, Vista, or Windows 7

  - by Mysticgeek

  When organizing your home network it’s easier to assign each computer it’s own IP address than using DHCP. Here we will take a look at doing it in XP, Vista, and Windows 7. If you have a home network with several computes and devices, it’s a good idea to assign each of them a specific address. If you use DHCP (Dynamic Host Configuration Protocol), each computer will request and be assigned an address every time it’s booted up. When you have to do troubleshooting on your network, it’s annoying going to each machine to figure out what IP they have. Using Static IPs prevents address conflicts between devices and allows you to manage them more easily. Assigning IPs to Windows is essentially the same process, but getting to where you need to be varies between each version. Windows 7 To change the computer’s IP address in Windows 7, type network and sharing into the Search box in the Start Menu and select Network and Sharing Center when it comes up.   Then when the Network and Sharing Center opens, click on Change adapter settings. Right-click on your local adapter and select Properties. In the Local Area Connection Properties window highlight Internet Protocol Version 4 (TCP/IPv4) then click the Properties button. Now select the radio button Use the following IP address and enter in the correct IP, Subnet mask, and Default gateway that corresponds with your network setup. Then enter your Preferred and Alternate DNS server addresses. Here we’re on a home network and using a simple Class C network configuration and Google DNS. Check Validate settings upon exit so Windows can find any problems with the addresses you entered. When you’re finished click OK. Now close out of the Local Area Connections Properties window. Windows 7 will run network diagnostics and verify the connection is good. Here we had no problems with it, but if you did, you could run the network troubleshooting wizard. Now you can open the command prompt and do an ipconfig  to see the network adapter settings have been successfully changed.   Windows Vista Changing your IP from DHCP to a Static address in Vista is similar to Windows 7, but getting to the correct location is a bit different. Open the Start Menu, right-click on Network, and select Properties. The Network and Sharing Center opens…click on Manage network connections. Right-click on the network adapter you want to assign an IP address and click Properties. Highlight Internet Protocol Version 4 (TCP/IPv4) then click the Properties button. Now change the IP, Subnet mask, Default Gateway, and DNS Server Addresses. When you’re finished click OK. You’ll need to close out of Local Area Connection Properties for the settings to go into effect. Open the Command Prompt and do an ipconfig to verify the changes were successful.   Windows XP In this example we’re using XP SP3 Media Center Edition and changing the IP address of the Wireless adapter. To set a Static IP in XP right-click on My Network Places and select Properties. Right-click on the adapter you want to set the IP for and select Properties. Highlight Internet Protocol (TCP/IP) and click the Properties button. Now change the IP, Subnet mask, Default Gateway, and DNS Server Addresses. When you’re finished click OK. You will need to close out of the Network Connection Properties screen before the changes go into effect.   Again you can verify the settings by doing an ipconfig in the command prompt. In case you’re not sure how to do this, click on Start then Run.   In the Run box type in cmd and click OK. Then at the prompt type in ipconfig and hit Enter. This will show the IP address for the network adapter you changed.   If you have a small office or home network, assigning each computer a specific IP address makes it a lot easier to manage and troubleshoot network connection problems.

• Securing an ASP.NET MVC 2 Application

  - by rajbk

  This post attempts to look at some of the methods that can be used to secure an ASP.NET MVC 2 Application called Northwind Traders Human Resources.  The sample code for the project is attached at the bottom of this post. We are going to use a slightly modified Northwind database. The screen capture from SQL server management studio shows the change. I added a new column called Salary, inserted some random salaries for the employees and then turned off AllowNulls.   The reporting relationship for Northwind Employees is shown below.   The requirements for our application are as follows: Employees can see their LastName, FirstName, Title, Address and Salary Employees are allowed to edit only their Address information Employees can see the LastName, FirstName, Title, Address and Salary of their immediate reports Employees cannot see records of non immediate reports.  Employees are allowed to edit only the Salary and Title information of their immediate reports. Employees are not allowed to edit the Address of an immediate report Employees should be authenticated into the system. Employees by default get the “Employee” role. If a user has direct reports, they will also get assigned a “Manager” role. We use a very basic empId/pwd scheme of EmployeeID (1-9) and password test$1. You should never do this in an actual application. The application should protect from Cross Site Request Forgery (CSRF). For example, Michael could trick Steven, who is already logged on to the HR website, to load a page which contains a malicious request. where without Steven’s knowledge, a form on the site posts information back to the Northwind HR website using Steven’s credentials. Michael could use this technique to give himself a raise :-) UI Notes The layout of our app looks like so: When Nancy (EmpID 1) signs on, she sees the default page with her details and is allowed to edit her address. If Nancy attempts to view the record of employee Andrew who has an employeeID of 2 (Employees/Edit/2), she will get a “Not Authorized” error page. When Andrew (EmpID 2) signs on, he can edit the address field of his record and change the title and salary of employees that directly report to him. Implementation Notes All controllers inherit from a BaseController. The BaseController currently only has error handling code. When a user signs on, we check to see if they are in a Manager role. We then create a FormsAuthenticationTicket, encrypt it (including the roles that the employee belongs to) and add it to a cookie. private void SetAuthenticationCookie(int employeeID, List<string> roles) { HttpCookiesSection cookieSection = (HttpCookiesSection) ConfigurationManager.GetSection("system.web/httpCookies"); AuthenticationSection authenticationSection = (AuthenticationSection) ConfigurationManager.GetSection("system.web/authentication"); FormsAuthenticationTicket authTicket = new FormsAuthenticationTicket( 1, employeeID.ToString(), DateTime.Now, DateTime.Now.AddMinutes(authenticationSection.Forms.Timeout.TotalMinutes), false, string.Join("|", roles.ToArray())); String encryptedTicket = FormsAuthentication.Encrypt(authTicket); HttpCookie authCookie = new HttpCookie(FormsAuthentication.FormsCookieName, encryptedTicket); if (cookieSection.RequireSSL || authenticationSection.Forms.RequireSSL) { authCookie.Secure = true; } HttpContext.Current.Response.Cookies.Add(authCookie); } We read this cookie back in Global.asax and set the Context.User to be a new GenericPrincipal with the roles we assigned earlier. protected void Application_AuthenticateRequest(Object sender, EventArgs e){ if (Context.User != null) { string cookieName = FormsAuthentication.FormsCookieName; HttpCookie authCookie = Context.Request.Cookies[cookieName]; if (authCookie == null) return; FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value); string[] roles = authTicket.UserData.Split(new char[] { '|' }); FormsIdentity fi = (FormsIdentity)(Context.User.Identity); Context.User = new System.Security.Principal.GenericPrincipal(fi, roles); }} We ensure that a user has permissions to view a record by creating a custom attribute AuthorizeToViewID that inherits from ActionFilterAttribute. public class AuthorizeToViewIDAttribute : ActionFilterAttribute{ IEmployeeRepository employeeRepository = new EmployeeRepository(); public override void OnActionExecuting(ActionExecutingContext filterContext) { if (filterContext.ActionParameters.ContainsKey("id") && filterContext.ActionParameters["id"] != null) { if (employeeRepository.IsAuthorizedToView((int)filterContext.ActionParameters["id"])) { return; } } throw new UnauthorizedAccessException("The record does not exist or you do not have permission to access it"); }} We add the AuthorizeToView attribute to any Action method that requires authorization. [HttpPost][Authorize(Order = 1)]//To prevent CSRF[ValidateAntiForgeryToken(Salt = Globals.EditSalt, Order = 2)]//See AuthorizeToViewIDAttribute class[AuthorizeToViewID(Order = 3)] [ActionName("Edit")]public ActionResult Update(int id){ var employeeToEdit = employeeRepository.GetEmployee(id); if (employeeToEdit != null) { //Employees can edit only their address //A manager can edit the title and salary of their subordinate string[] whiteList = (employeeToEdit.IsSubordinate) ? new string[] { "Title", "Salary" } : new string[] { "Address" }; if (TryUpdateModel(employeeToEdit, whiteList)) { employeeRepository.Save(employeeToEdit); return RedirectToAction("Details", new { id = id }); } else { ModelState.AddModelError("", "Please correct the following errors."); } } return View(employeeToEdit);} The Authorize attribute is added to ensure that only authorized users can execute that Action. We use the TryUpdateModel with a white list to ensure that (a) an employee is able to edit only their Address and (b) that a manager is able to edit only the Title and Salary of a subordinate. This works in conjunction with the AuthorizeToViewIDAttribute. The ValidateAntiForgeryToken attribute is added (with a salt) to avoid CSRF. The Order on the attributes specify the order in which the attributes are executed. The Edit View uses the AntiForgeryToken helper to render the hidden token: ......<% using (Html.BeginForm()) {%><%=Html.AntiForgeryToken(NorthwindHR.Models.Globals.EditSalt)%><%= Html.ValidationSummary(true, "Please correct the errors and try again.") %><div class="editor-label"> <%= Html.LabelFor(model => model.LastName) %></div><div class="editor-field">...... The application uses View specific models for ease of model binding. public class EmployeeViewModel{ public int EmployeeID; [Required] [DisplayName("Last Name")] public string LastName { get; set; } [Required] [DisplayName("First Name")] public string FirstName { get; set; } [Required] [DisplayName("Title")] public string Title { get; set; } [Required] [DisplayName("Address")] public string Address { get; set; } [Required] [DisplayName("Salary")] [Range(500, double.MaxValue)] public decimal Salary { get; set; } public bool IsSubordinate { get; set; }} To help with displaying readonly/editable fields, we use a helper method. //Simple extension method to display a TextboxFor or DisplayFor based on the isEditable variablepublic static MvcHtmlString TextBoxOrLabelFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression, bool isEditable){ if (isEditable) { return htmlHelper.TextBoxFor(expression); } else { return htmlHelper.DisplayFor(expression); }} The helper method is used in the view like so: <%=Html.TextBoxOrLabelFor(model => model.Title, Model.IsSubordinate)%> As mentioned in this post, there is a much easier way to update properties on an object. Download Demo Project VS 2008, ASP.NET MVC 2 RTM Remember to change the connectionString to point to your Northwind DB NorthwindHR.zip Feedback and bugs are always welcome :-)

• Image Preview in ASP.NET MVC

  - by imran_ku07

    Introduction :         Previewing an image is a great way to improve the UI of your site. Also it is always best to check the file type, size and see a preview before submitting the whole form. There are some ways to do this using simple JavaScript but not work in all browsers (like FF3).In this Article I will show you how do this using ASP.NET MVC application. You also see how this will work in case of nested form.   Description :          Create a new ASP.NET MVC project and then add a file upload and image control into your View. <form id="form1" method="post" action="NerdDinner/ImagePreview/AjaxSubmit">            <table>                <tr>                    <td>                        <input type="file" name="imageLoad1" id="imageLoad1"  onchange="ChangeImage(this,'#imgThumbnail')" />                    </td>                </tr>                <tr>                    <td align="center">                        <img src="images/TempImage.gif" id="imgThumbnail" height="200px" width="200px">                     </td>                </tr>            </table>        </form>           Note that here NerdDinner is refers to the virtual directory name, ImagePreview is the Controller and ImageLoad is the action name which you will see shortly          I will use the most popular jQuery form plug-in, that turns a form into an AJAX form with very little code. Therefore you must get these from Jquery site and then add these files into your page.          <script src="NerdDinner/Scripts/jquery-1.3.2.js" type="text/javascript"></script>        <script src="NerdDinner/Scripts/jquery.form.js" type="text/javascript"></script>            Then add the javascript function. <script type="text/javascript">function ChangeImage(fileId,imageId){ $("#form1").ajaxSubmit({success: function(responseText){ var d=new Date(); $(imageId)[0].src="NerdDinner/ImagePreview/ImageLoad?a="+d.getTime(); } });}</script>             This function simply submit the form named form1 asynchronously to ImagePreviewController's method AjaxSubmit and after successfully receiving the response, it will set the image src property to the action method ImageLoad. Here I am also adding querystring, preventing the browser to serve the cached image.           Now I will create a new Controller named ImagePreviewController. public class ImagePreviewController : Controller { [AcceptVerbs(HttpVerbs.Post)] public ActionResult AjaxSubmit(int? id) { Session["ContentLength"] = Request.Files[0].ContentLength; Session["ContentType"] = Request.Files[0].ContentType; byte[] b = new byte[Request.Files[0].ContentLength]; Request.Files[0].InputStream.Read(b, 0, Request.Files[0].ContentLength); Session["ContentStream"] = b; return Content( Request.Files[0].ContentType+";"+ Request.Files[0].ContentLength ); } public ActionResult ImageLoad(int? id) { byte[] b = (byte[])Session["ContentStream"]; int length = (int)Session["ContentLength"]; string type = (string)Session["ContentType"]; Response.Buffer = true; Response.Charset = ""; Response.Cache.SetCacheability(HttpCacheability.NoCache); Response.ContentType = type; Response.BinaryWrite(b); Response.Flush(); Session["ContentLength"] = null; Session["ContentType"] = null; Session["ContentStream"] = null; Response.End(); return Content(""); } }             The AjaxSubmit action method will save the image in Session and return content type and content length in response. ImageLoad action method will return the contents of image in response.Then clear these Sessions.           Just run your application and see the effect.   Checking Size and Content Type of File:          You may notice that AjaxSubmit action method is returning both content type and content length. You can check both properties before submitting your complete form.     $(myform).ajaxSubmit({success: function(responseText)            {                                var contentType=responseText.substring(0,responseText.indexOf(';'));                var contentLength=responseText.substring(responseText.indexOf(';')+1);                // Here you can do your validation                var d=new Date();                $(imageId)[0].src="http://weblogs.asp.net/MoneypingAPP/ImagePreview/ImageLoad?a="+d.getTime();            }        });  Handling Nested Form Case:          The above code will work if you have only one form. But this is not the case always.You may have a form control which wraps all the controls and you do not want to submit the whole form, just for getting a preview effect.           In this case you need to create a dynamic form control using JavaScript, and then add file upload control to this form and submit the form asynchronously  function ChangeImage(fileId,imageId)         {            var myform=document.createElement("form");                    myform.action="NerdDinner/ImagePreview/AjaxSubmit";            myform.enctype="multipart/form-data";            myform.method="post";            var imageLoad=document.getElementById(fileId).cloneNode(true);            myform.appendChild(imageLoad);            document.body.appendChild(myform);            $(myform).ajaxSubmit({success: function(responseText)                {                                    var contentType=responseText.substring(0,responseText.indexOf(';'));                    var contentLength=responseText.substring(responseText.indexOf(';')+1);                    var d=new Date();                    $(imageId)[0].src="http://weblogs.asp.net/MoneypingAPP/ImagePreview/ImageLoad?a="+d.getTime();                    document.body.removeChild(myform);                }            });        }            You also need append the child in order to send request and remove them after receiving response.

• Building an HTML5 App with ASP.NET

  - by Stephen Walther

  I’m teaching several JavaScript and ASP.NET workshops over the next couple of months (thanks everyone!) and I thought it would be useful for my students to have a really easy to use JavaScript reference. I wanted a simple interactive JavaScript reference and I could not find one so I decided to put together one of my own. I decided to use the latest features of JavaScript, HTML5 and jQuery such as local storage, offline manifests, and jQuery templates. What could be more appropriate than building a JavaScript Reference with JavaScript? You can try out the application by visiting: http://Superexpert.com/JavaScriptReference Because the app takes advantage of several advanced features of HTML5, it won’t work with Internet Explorer 6 (but really, you should stop using that browser). I have tested it with IE 8, Chrome 8, Firefox 3.6, and Safari 5. You can download the source for the JavaScript Reference application at the end of this article. Superexpert JavaScript Reference Let me provide you with a brief walkthrough of the app. When you first open the application, you see the following lookup screen: As you type the name of something from the JavaScript language, matching results are displayed: You can click the details link for any entry to view details for an entry in a modal dialog: Alternatively, you can click on any of the tabs -- Objects, Functions, Properties, Statements, Operators, Comments, or Directives -- to filter results by type of syntax. For example, you might want to see a list of all JavaScript built-in objects: You can login to the application to make modification to the application: After you login, you can add, update, or delete entries in the reference database: HTML5 Local Storage The application takes advantage of HTML5 local storage to store all of the reference entries on the local browser. IE 8, Chrome 8, Firefox 3.6, and Safari 5 all support local storage. When you open the application for the first time, all of the reference entries are transferred to the browser. The data is stored persistently. Even if you shutdown your computer and return to the application many days later, the data does not need to be transferred again. Whenever you open the application, the app checks with the server to see if any of the entries have been updated on the server. If there have been updates, then only the updates are transferred to the browser and the updates are merged with the existing entries in local storage. After the reference database has been transferred to your browser once, only changes are transferred in the future. You get two benefits from using local storage. First, the application loads very fast and works very fast after the data has been loaded once. The application does not query the server whenever you filter or view entries. All of the data is persisted in the browser. Second, you can browse the JavaScript reference even when you are not connected to the Internet (when you are on the proverbial airplane). The JavaScript Reference works as an offline application for browsers that support offline applications (unfortunately, not IE). When using Google Chrome, you can easily view the contents of local storage by selecting Tools, Developer Tools (CTRL-SHIFT I) and selecting Storage, Local Storage: The JavaScript Reference app stores two items in local storage: entriesLastUpdated and entries. HTML5 Offline App For browsers that support HTML5 offline applications – Chrome 8 and Firefox 3.6 but not Internet Explorer – you do not need to be connected to the Internet to use the JavaScript Reference. The JavaScript Reference can execute entirely on your machine just like any other desktop application. When you first open the application with Firefox, you are presented with the following warning: Notice the notification bar that asks whether you want to accept offline content. If you click the Allow button then all of the files (generated ASPX, images, CSS, JavaScript) needed for the JavaScript Reference will be stored on your local computer. Automatic Script Minification and Combination All of the custom JavaScript files are combined and minified automatically whenever the application is built with Visual Studio. All of the custom scripts are contained in a folder named App_Scripts: When you perform a build, the combine.js and combine.debug.js files are generated. The Combine.config file contains the list of files that should be combined (importantly, it specifies the order in which the files should be combined). Here’s the contents of the Combine.config file:   <?xml version="1.0"?> <combine> <scripts> <file path="compat.js" /> <file path="storage.js" /> <file path="serverData.js" /> <file path="entriesHelper.js" /> <file path="authentication.js" /> <file path="default.js" /> </scripts> </combine>   jQuery and jQuery UI The JavaScript Reference application takes heavy advantage of jQuery and jQuery UI. In particular, the application uses jQuery templates to format and display the reference entries. Each of the separate templates is stored in a separate ASP.NET user control in a folder named Templates: The contents of the user controls (and therefore the templates) are combined in the default.aspx page: <!-- Templates --> <user:EntryTemplate runat="server" /> <user:EntryDetailsTemplate runat="server" /> <user:BrowsersTemplate runat="server" /> <user:EditEntryTemplate runat="server" /> <user:EntryDetailsCloudTemplate runat="server" /> When the default.aspx page is requested, all of the templates are retrieved in a single page. WCF Data Services The JavaScript Reference application uses WCF Data Services to retrieve and modify database data. The application exposes a server-side WCF Data Service named EntryService.svc that supports querying, adding, updating, and deleting entries. jQuery Ajax calls are made against the WCF Data Service to perform the database operations from the browser. The OData protocol makes this easy. Authentication is handled on the server with a ChangeInterceptor. Only authenticated users are allowed to update the JavaScript Reference entry database. JavaScript Unit Tests In order to build the JavaScript Reference application, I depended on JavaScript unit tests. I needed the unit tests, in particular, to write the JavaScript merge functions which merge entry change sets from the server with existing entries in browser local storage. In order for unit tests to be useful, they need to run fast. I ran my unit tests after each build. For this reason, I did not want to run the unit tests within the context of a browser. Instead, I ran the unit tests using server-side JavaScript (the Microsoft Script Control). The source code that you can download at the end of this blog entry includes a project named JavaScriptReference.UnitTests that contains all of the JavaScripts unit tests. JavaScript Integration Tests Because not every feature of an application can be tested by unit tests, the JavaScript Reference application also includes integration tests. I wrote the integration tests using Selenium RC in combination with ASP.NET Unit Tests. The Selenium tests run against all of the target browsers for the JavaScript Reference application: IE 8, Chrome 8, Firefox 3.6, and Safari 5. For example, here is the Selenium test that checks whether authenticating with a valid user name and password correctly switches the application to Admin Mode: [TestMethod] [HostType("ASP.NET")] [UrlToTest("http://localhost:26303/JavaScriptReference")] [AspNetDevelopmentServerHost(@"C:\Users\Stephen\Documents\Repos\JavaScriptReference\JavaScriptReference\JavaScriptReference", "/JavaScriptReference")] public void TestValidLogin() { // Run test for each controller foreach (var controller in this.Controllers) { var selenium = controller.Value; var browserName = controller.Key; // Open reference page. selenium.Open("http://localhost:26303/JavaScriptReference/default.aspx"); // Click login button displays login form selenium.Click("btnLogin"); Assert.IsTrue(selenium.IsVisible("loginForm"), "Login form appears after clicking btnLogin"); // Enter user name and password selenium.Type("userName", "Admin"); selenium.Type("password", "secret"); selenium.Click("btnDoLogin"); // Should set adminMode == true selenium.WaitForCondition("selenium.browserbot.getCurrentWindow().adminMode==true", "30000"); } }   The results for running the Selenium tests appear in the Test Results window just like the unit tests: The Selenium tests take much longer to execute than the unit tests. However, they provide test coverage for actual browsers. Furthermore, if you are using Visual Studio ALM, you can run the tests automatically every night as part of your standard nightly build. You can view the Selenium tests by opening the JavaScriptReference.QATests project. Summary I plan to write more detailed blog entries about this application over the next week. I want to discuss each of the features – HTML5 local storage, HTML5 offline apps, jQuery templates, automatic script combining and minification, JavaScript unit tests, Selenium tests -- in more detail. You can download the source control for the JavaScript Reference Application by clicking the following link: Download You need Visual Studio 2010 and ASP.NET 4 to build the application. Before running the JavaScript unit tests, install the Microsoft Script Control. Before running the Selenium tests, start the Selenium server by running the StartSeleniumServer.bat file located in the JavaScriptReference.QATests project.

• I&rsquo;m sorry RPGs, it&rsquo;s not you, it&rsquo;s me: The birth of my game idea

  - by George Clingerman

  One of the things I’ve had to give up in order to have some development time at night is gaming. It’s something I refused to admit for years but I’ve just had to face the facts. I’m no longer a gamer. I just don’t have hours and hours of free time to pour into gaming and when I do have hours and hours of free time I want to pour them into game development. That doesn’t mean I don’t game at all! I play games pretty much every day. It just means I’ve moved more into the casual game realm. It’s all I have time for when juggling priorities in my life. That means that games like Gears of War 2 sit shrink wrapped on my shelf and although I popped Dragon Age into my Xbox 360 one time, I barely made it through the opening sequence and haven’t had time to sit down and play again. Instead I’m playing short games like Jamestown, Atom Zombie Smasher, Fortix or if I have time to jump in and play a few rounds maybe some Monday Night Combat or Team Fortress 2. These are games I can instantly get into and play for just a short period of time and then walk away. Breath of Death VII saved my life: Back in the day (way, way back in the day) I used to be a pretty big RPG fan. Not big by a lot of RPG gamers' standards (most of the RPGs RPG fans about I’ve never heard of) but I used to LOVE to play them on the NES, SNES and Genesis and considered that my genre. Final Fantasy, Shining in the Darkness, Bard’s Tale, Faxanadu, Shadowrun, Ultima, Dragon Warrior, Chrono Trigger, Phantasy Star, Shining Force and well the list could go on but those are the ones I remember off the top of my head. I loved playing RPGs and they were my games of choice. After my first son was born (this was just about 12 years ago), I tried to continue playing RPGs and purchased games like Baldur’s Gate I & II, Neverwinter Nights, Fable, then a few of the Final Fantasy’s then Kingdom Hearts. I kept buying these games and then only playing for about fifteen minutes and never getting back to them. I still loved RPGs but they just no longer fit into my life (I still haven’t accepted that since I still purchased Dragon Age II for some reason and convinced myself I’d find the time). Adding three more sons to the mix (that’s 4 total) didn’t help much to finding more RPG time (except for Breath of Death VII and other XBLIG RPG titles, thanks guys!) All work and no RPG: A few months ago as I was sitting thinking about the lack of RPGs in my life and talking to my wife about why I wish RPGs were different and easier for a dad like me to get into. She seemed like she was listening, so I started listing all the things that made them impossible for me to play. Here’s a short list I came up with. They take 15 billion hours to complete I have a few minutes at a time I can grab to play them if I want to have time to code. At that rate it would take me 9 trillion years to beat just one RPG. There’s such long spans of times between when I can play them I forget what I was even doing so I have to spend most of the playtime I have just figuring that out and then my play time is over. Repeat. I’ll never finish one and since it takes so long to get to the fun part in an RPG, I’m never having fun. RPGs aren’t fun if you don’t have hours to play them at a time. As you can see based on my science and math, RPGs aren’t fun for me any more. From there my brain started toying around with ideas of RPGs that would work for me. They would have to be a short RPG, you know one you could beat in a single play session. A dad sized play session. I started thinking, wouldn’t it be awesome if there was a fifteen minute RPG? That got me laughing and I took that as a good sign that it sounded fun and so I thought about it a little more. I immediately discarded the idea of doing a real RPG. I’m sure a short RPG like that could be done but it wasn’t the vibe that I had in my head. No this was going to be something that just had the core essence of an RPG. In reality what I’d be making would be more of an arcade style game. One with high scores and lots of crazy action on the screen. And that’s when it hit me. It would be a speed run RPG. That’s the basics of the game I’m working on.   The Elevator Pitch: It’s a 2D top down RPG themed arcade game focused on speed. It sounds like an RPG, smells like an RPG but it’s merely emulating an RPG. The game is focused on fun and mayhem in RPG form with players leveling up in seconds instead of hours and rushing to finish quests as quickly as possible because they’ve only got fifteen minutes before EVIL overtakes the world. If the player takes longer than fifteen minutes, it’s game over man. One to four player co-operative play to really see just how fast players can level up and beat the game. Gamers will compete on leaderboards for bragging rights for fastest 1, 2, 3, and 4 player speed runs, lowest leveled characters to beat the game, highest leveled characters to beat the game and so on. Times will be tracked for everything from how long a player sat distributing stats, equipping items, talking to NPCs to running around the level. These stats will be shown at the end of each quest/level so the players can work on improving their speed run for that part of the game next time around. It’s the perfect RPG for those of us who only have fifteen minutes of game time! Where I’m at: I’m still at the prototyping stage attempting to but all the basic framework pieces in place that will at minimum give me one level to rush through. I’ve been working on this prototype for about a month now though so I’m going to have to step it up a bit or I’m not going to get finished in time (remember I’ve only got 85 days left!) Lots of the game code is in place (although pretty sloppy) but I still can’t play through that first quest/level just yet. That’s my goal to finish up by the end of next Sunday (3/25/2012). You can all hold me to that and cheer me on or heckle me throughout the week. Either way that should help me stay a bit more motivated and focused. In my head this feels like it’s going to be a fun game so I’m looking forward to seeing how it actually plays!

• Why is Perl's smart-match operator considered broken?

  - by Sean McMillan

  I've seen a number of comments across the web Perl's smart-match operator is broken. I know it originally was part of Perl 6, then was implemented in Perl 5.10 off of an old version of the spec, and was then corrected in 5.10.1 to match the current Perl 6 spec. Is the problem fixed in 5.10.1+, or are there other problems with the smart-match operator that make it troublesome in practice? What are the problems? Is there a yet-more-updated version (Perl 6, perhaps) that fixes the problems?

• Apache2 worker mpm too many processes

  - by delerious010

  I've got Apache installed with the worker mpm which seems to have too many processes active in spite of the configurations in place. I'll detail the configs below : StartServers 2 MinSpareThreads 10 MaxSpareThreads 25 ThreadsPerChild 25 MaxClients 150 Based on these settings, we should be seeing a maximum of 1 Apache control process (uid:root) and 6 Apache client processes (uid:www). This being due to MaxClients/ThreadsPerChild. However, I'm seeing a total of 1 Apache control process and 9 Apache client processes. init -- apache2(root) -- -- apache2(www) -- -- apache2(www) -- 1 thread -- -- apache2(www) -- 26 threads -- -- apache2(www) -- 26 threads init -- apache2(www) -- 2 threads -- apache2(www) -- apache2(www) -- apache2(www) We do not make it a habit of restarting Apache nor the Server, and will perform a reload 2-3 times a day at times so as to add new VHOSTs. Would anyone be able to enlighten me as to what might be causing this ? enter code here

• Podcast: The Invisible UI : Natural User Interfaces with Josh Blake

  - by craigshoemaker

  Josh Blake of Infostrat joins Pixel8 to discuss NUI development in .NET. Josh is the author of the upcoming book Multitouch on Windows from Manning. Reaching far beyond theory and the niche market of Microsoft Surface, NUI development is now possible with Silverlight and WPF development on Windows 7 and Windows 7 Mobile devices. Subscribe to the podcast! The Natural User Interface (NUI) was a prominent force at MIX10. What is NUI? Wikipedia defines it as: Natural user interface, or NUI, is the common parlance used by designers and developers of computer interfaces to refer to a user interface that is effectively invisible, or becomes invisible with successive learned interactions, to its users. The word natural is used because most computer interfaces use artificial control devices whose operation has to be learned. A NUI relies on a user being able to carry out relatively natural motions, movements or gestures that they quickly discover control the computer application or manipulate the on-screen content. The most descriptive identifier of a NUI is the lack of a physical keyboard and/or mouse. In our interview Josh demystifies what NUI is, makes a distinction between gestures and manipulations, and talks about what is possible today for NUI development. For more from Josh make sure to check out his book: and watch his MIX Presentation: Developing Natural User Interfaces with Microsoft Silverlight and WPF 4 Touch Resources Mentioned in the Show Check out the following videos that show the roots and future of NUI development: Jeff Han's Multi-Touch TED Presentation Microsoft Surface Project Natal MIX10 Day 2 Keynote A few times during our talk Bill Buxton’s work is mentioned.

• How to Specify AssemblyKeyFile Attribute in .NET Assembly and Issues

  How to specify strong key file in assembly? Answer: You can specify snk file information using following line [assembly: AssemblyKeyFile(@"c:\Key2.snk")] Where to specify an strong key file (snk file)? Answer: You have two options to specify the AssemblyKeyFile infromation. 1. In class 2. In AssemblyInfo.cs [assembly: AssemblyKeyFile(@"c:\Key2.snk")] 1. In Class you must specify above line before defining namespace of the class and after all the imports or usings Example: See Line 7 in bellow sample class using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Reflection;[assembly: AssemblyKeyFile(@"c:\Key1.snk")]namespace Csharp3Part1{ class Person { public string GetName() { return "Smith"; } }}2. In AssemblyInfo.cs You can aslo specify assembly information in AssemblyInfo.cs Example: See Line 16 in bellow sample AssemblyInfo.csusing System.Reflection;using System.Runtime.CompilerServices;using System.Runtime.InteropServices;// General Information about an assembly is controlled through the following// set of attributes. Change these attribute values to modify the information// associated with an assembly.[assembly: AssemblyTitle("Csharp3Part1")][assembly: AssemblyDescription("")][assembly: AssemblyConfiguration("")][assembly: AssemblyCompany("Deloitte")][assembly: AssemblyProduct("Csharp3Part1")][assembly: AssemblyCopyright("Copyright © Deloitte 2009")][assembly: AssemblyTrademark("")][assembly: AssemblyCulture("")][assembly: AssemblyKeyFile(@"c:\Key1.snk")]// Setting ComVisible to false makes the types in this assembly not visible// to COM components. If you need to access a type in this assembly from// COM, set the ComVisible attribute to true on that type.[assembly: ComVisible(false)]// The following GUID is for the ID of the typelib if this project is exposed to COM[assembly: Guid("4350396f-1a5c-4598-a79f-2e1f219654f3")]// Version information for an assembly consists of the following four values://// Major Version// Minor Version// Build Number// Revision//// You can specify all the values or you can default the Build and Revision Numbers// by using the '*' as shown below:// [assembly: AssemblyVersion("1.0.*")][assembly: AssemblyVersion("1.0.0.0")][assembly: AssemblyFileVersion("1.0.0.0")]Issues:You should not sepcify this in following ways. 1. In multiple classes. 2. In both class and AssemblyInfo.cs If you did wrong in either one of the above ways, Visual Studio or C#/VB.NET compilers shows following Error Duplicate 'AssemblyKeyFile' attribute and warning Use command line option '/keyfile' or appropriate project settings instead of 'AssemblyKeyFile' To avoid this, Please specity your keyfile information only one time either only in one class or in AssemblyInfo.cs file. It is suggested to specify this at AssemblyInfo.cs file You might also encounter the errors like Error: type or namespace name 'AssemblyKeyFileAttribute' and 'AssemblyKeyFile' could not be found.

• A Look at the GridView's New Sorting Styles in ASP.NET 4.0

  Like every Web control in the ASP.NET toolbox, the GridView includes a variety of style-related properties, including CssClass, Font, ForeColor, BackColor, Width, Height, and so on. The GridView also includes style properties that apply to certain classes of rows in the grid, such as RowStyle, AlternatingRowStyle, HeaderStyle, and PagerStyle. Each of these meta-style properties offer the standard style properties (CssClass, Font, etc.) as subproperties. In ASP.NET 4.0, Microsoft added four new style properties to the GridView control: SortedAscendingHeaderStyle, SortedAscendingCellStyle, SortedDescendingHeaderStyle, and SortedDescendingCellStyle. These four properties are meta-style properties like RowStyle and HeaderStyle, but apply to column of cells rather than a row. These properties only apply when the GridView is sorted - if the grid's data is sorted in ascending order then the SortedAscendingHeaderStyle and SortedAscendingCellStyle properties define the styles for the column the data is sorted by. The SortedDescendingHeaderStyle and SortedDescendingCellStyle properties apply to the sorted column when the results are sorted in descending order. These four new properties make it easier to customize the appearance of the column by which the data is sorted. Using these properties along with a touch of Cascading Style Sheets (CSS) it is possible to add up and down arrows to the sorted column's header to indicate whether the data is sorted in ascending or descending order. Likewise, these properties can be used to shade the sorted column or make its text bold. This article shows how to use these four new properties to style the sorted column. Read on to learn more!

• ASP.NET MVC Postbacks and HtmlHelper Controls ignoring Model Changes

  - by Rick Strahl

  So here's a binding behavior in ASP.NET MVC that I didn't really get until today: HtmlHelpers controls (like .TextBoxFor() etc.) don't bind to model values on Postback, but rather get their value directly out of the POST buffer from ModelState. Effectively it looks like you can't change the display value of a control via model value updates on a Postback operation. To demonstrate here's an example. I have a small section in a document where I display an editable email address: This is what the form displays on a GET operation and as expected I get the email value displayed in both the textbox and plain value display below, which reflects the value in the mode. I added a plain text value to demonstrate the model value compared to what's rendered in the textbox. The relevant markup is the email address which needs to be manipulated via the model in the Controller code. Here's the Razor markup: <div class="fieldcontainer"> <label> Email: &nbsp; <small>(username and <a href="http://gravatar.com">Gravatar</a> image)</small> </label> <div> @Html.TextBoxFor( mod=> mod.User.Email, new {type="email",@class="inputfield"}) @Model.User.Email </div> </div>   So, I have this form and the user can change their email address. On postback the Post controller code then asks the business layer whether the change is allowed. If it's not I want to reset the email address back to the old value which exists in the database and was previously store. The obvious thing to do would be to modify the model. Here's the Controller logic block that deals with that:// did user change email? if (!string.IsNullOrEmpty(oldEmail) && user.Email != oldEmail) { if (userBus.DoesEmailExist(user.Email)) { userBus.ValidationErrors.Add("New email address exists already. Please…"); user.Email = oldEmail; } else // allow email change but require verification by forcing a login user.IsVerified = false; }… model.user = user; return View(model); The logic is straight forward - if the new email address is not valid because it already exists I don't want to display the new email address the user entered, but rather the old one. To do this I change the value on the model which effectively does this:model.user.Email = oldEmail; return View(model); So when I press the Save button after entering in my new email address ([email protected]) here's what comes back in the rendered view: Notice that the textbox value and the raw displayed model value are different. The TextBox displays the POST value, the raw value displays the actual model value which are different. This means that MVC renders the textbox value from the POST data rather than from the view data when an Http POST is active. Now I don't know about you but this is not the behavior I expected - initially. This behavior effectively means that I cannot modify the contents of the textbox from the Controller code if using HtmlHelpers for binding. Updating the model for display purposes in a POST has in effect - no effect. (Apr. 25, 2012 - edited the post heavily based on comments and more experimentation) What should the behavior be? After getting quite a few comments on this post I quickly realized that the behavior I described above is actually the behavior you'd want in 99% of the binding scenarios. You do want to get the POST values back into your input controls at all times, so that the data displayed on a form for the user matches what they typed. So if an error occurs, the error doesn't mysteriously disappear getting replaced either with a default value or some value that you changed on the model on your own. Makes sense. Still it is a little non-obvious because the way you create the UI elements with MVC, it certainly looks like your are binding to the model value:@Html.TextBoxFor( mod=> mod.User.Email, new {type="email",@class="inputfield",required="required" }) and so unless one understands a little bit about how the model binder works this is easy to trip up. At least it was for me. Even though I'm telling the control which model value to bind to, that model value is only used initially on GET operations. After that ModelState/POST values provide the display value. Workarounds The default behavior should be fine for 99% of binding scenarios. But if you do need fix up values based on your model rather than the default POST values, there are a number of ways that you can work around this. Initially when I ran into this, I couldn't figure out how to set the value using code and so the simplest solution to me was simply to not use the MVC Html Helper for the specific control and explicitly bind the model via HTML markup and @Razor expression: <input type="text" name="User.Email" id="User_Email" value="@Model.User.Email" /> And this produces the right result. This is easy enough to create, but feels a little out of place when using the @Html helpers for everything else. As you can see by the difference in the name and id values, you also are forced to remember the naming conventions that MVC imposes in order for ModelBinding to work properly which is a pain to remember and set manually (name is the same as the property with . syntax, id replaces dots with underlines). Use the ModelState Some of my original confusion came because I didn't understand how the model binder works. The model binder basically maintains ModelState on a postback, which holds a value and binding errors for each of the Post back value submitted on the page that can be mapped to the model. In other words there's one ModelState entry for each bound property of the model. Each ModelState entry contains a value property that holds AttemptedValue and RawValue properties. The AttemptedValue is essentially the POST value retrieved from the form. The RawValue is the value that the model holds. When MVC binds controls like @Html.TextBoxFor() or @Html.TextBox(), it always binds values on a GET operation. On a POST operation however, it'll always used the AttemptedValue to display the control. MVC binds using the ModelState on a POST operation, not the model's value. So, if you want the behavior that I was expecting originally you can actually get it by clearing the ModelState in the controller code:ModelState.Clear(); This clears out all the captured ModelState values, and effectively binds to the model. Note this will produce very similar results - in fact if there are no binding errors you see exactly the same behavior as if binding from ModelState, because the model has been updated from the ModelState already and binding to the updated values most likely produces the same values you would get with POST back values. The big difference though is that any values that couldn't bind - like say putting a string into a numeric field - will now not display back the value the user typed, but the default field value or whatever you changed the model value to. This is the behavior I was actually expecting previously. But - clearing out all values might be a bit heavy handed. You might want to fix up one or two values in a model but rarely would you want the entire model to update from the model. So, you can also clear out individual values on an as needed basis:if (userBus.DoesEmailExist(user.Email)) { userBus.ValidationErrors.Add("New email address exists already. Please…"); user.Email = oldEmail; ModelState.Remove("User.Email"); } This allows you to remove a single value from the ModelState and effectively allows you to replace that value for display from the model. Why? While researching this I came across a post from Microsoft's Brad Wilson who describes the default binding behavior best in a forum post: The reason we use the posted value for editors rather than the model value is that the model may not be able to contain the value that the user typed. Imagine in your "int" editor the user had typed "dog". You want to display an error message which says "dog is not valid", and leave "dog" in the editor field. However, your model is an int: there's no way it can store "dog". So we keep the old value. If you don't want the old values in the editor, clear out the Model State. That's where the old value is stored and pulled from the HTML helpers. There you have it. It's not the most intuitive behavior, but in hindsight this behavior does make some sense even if at first glance it looks like you should be able to update values from the model. The solution of clearing ModelState works and is a reasonable one but you have to know about some of the innards of ModelState and how it actually works to figure that out.© Rick Strahl, West Wind Technologies, 2005-2012Posted in ASP.NET  MVC   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();
