  • Table prefix for MySqlMembershipProvider

    - by choudeshell
    I have MySqlMembershipProvider working with Asp.Net MVC. My question is how can I configure the table prefix... so instead of 'my_aspnet_' prefix on the tables, I want this to be either none or defined by me. My web.config: <?xml version="1.0"?> <add name="ApplicationServices" connectionString="server=localhost;user id=root;Password=*********;database=sparkSources" providerName="MySql.Data.MySqlClient"/> <authentication mode="Forms"> <forms loginUrl="~/Account/LogOn" timeout="2880" /> </authentication> <membership defaultProvider="MySqlMembershipProvider"> <providers> <clear/> <add name="MySqlMembershipProvider" type="MySql.Web.Security.MySQLMembershipProvider, MySql.Web, Version=6.3.4.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" autogenerateschema="true" tablePrefix="ss" connectionStringName="ApplicationServices" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" passwordFormat="Hashed" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" passwordStrengthRegularExpression="" applicationName="sparkSources" /> </providers> </membership> <profile> <providers> <clear/> <add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider" connectionStringName="ApplicationServices" applicationName="/" /> </providers> </profile> <roleManager enabled="false"> <providers> <clear/> <add name="AspNetSqlRoleProvider" type="System.Web.Security.SqlRoleProvider" connectionStringName="ApplicationServices" applicationName="/" /> <add name="AspNetWindowsTokenRoleProvider" type="System.Web.Security.WindowsTokenRoleProvider" applicationName="/" /> </providers> </roleManager> <pages> <namespaces> <add namespace="System.Web.Mvc" /> <add namespace="System.Web.Mvc.Ajax" /> <add namespace="System.Web.Mvc.Html" /> <add namespace="System.Web.Routing" /> </namespaces> </pages>

  • How to implement a caching model without violating MVC pattern?

    - by RPM1984
    Hi Guys, I have an ASP.NET MVC 3 (Razor) Web Application, with a particular page which is highly database intensive, and user experience is of the upmost priority. Thus, i am introducing caching on this particular page. I'm trying to figure out a way to implement this caching pattern whilst keeping my controller thin, like it currently is without caching: public PartialViewResult GetLocationStuff(SearchPreferences searchPreferences) { var results = _locationService.FindStuffByCriteria(searchPreferences); return PartialView("SearchResults", results); } As you can see, the controller is very thin, as it should be. It doesn't care about how/where it is getting it's info from - that is the job of the service. A couple of notes on the flow of control: Controllers get DI'ed a particular Service, depending on it's area. In this example, this controller get's a LocationService Services call through to an IQueryable<T> Repository and materialize results into T or ICollection<T>. How i want to implement caching: I can't use Output Caching - for a few reasons. First of all, this action method is invoked from the client-side (jQuery/AJAX), via [HttpPost], which according to HTTP standards should not be cached as a request. Secondly, i don't want to cache purely based on the HTTP request arguments - the cache logic is a lot more complicated than that - there is actually two-level caching going on. As i hint to above, i need to use regular data-caching, e.g Cache["somekey"] = someObj;. I don't want to implement a generic caching mechanism where all calls via the service go through the cache first - i only want caching on this particular action method. First thought's would tell me to create another service (which inherits LocationService), and provide the caching workflow there (check cache first, if not there call db, add to cache, return result). That has two problems: The services are basic Class Libraries - no references to anything extra. I would need to add a reference to System.Web here. I would have to access the HTTP Context outside of the web application, which is considered bad practice, not only for testability, but in general - right? I also thought about using the Models folder in the Web Application (which i currently use only for ViewModels), but having a cache service in a models folder just doesn't sound right. So - any ideas? Is there a MVC-specific thing (like Action Filter's, for example) i can use here? General advice/tips would be greatly appreciated.

  • Log4Net with ASP.NET MVC...nothing happens...

    - by twal
    I am trying to use log4Net with Asp.net MVC and I cannot get anything to happen with it. i created a config that is in my web project root. Here is that config file. <log4net> <root> <level value="INFO" /> <appender-ref ref="RollingLogFileAppender"/> </root> <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="C:\DWSApplicationFiles\AppLogs\app.log" /> <appendToFile value="true" /> <rollingStyle value="Size" /> <maxSizeRollBackups value="10" /> <maximumFileSize value="100KB" /> <staticLogFileName value="true" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%d [%t]%-5p %c [%x] - %m%n" /> </layout> </appender> <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="C:\DWSApplicationFiles\AppLogs\app.log" /> <appendToFile value="false" /> <datePattern value="-dddd" /> <rollingStyle value="Date" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%d [%t]%-5p %c [%x] - %m%n" /> </layout> </appender> </log4net> Before I am asked, yes the application has permissions to write to the directory. I use have tested this and the application has permissions to this directoy. here is where I am trying to use log4net. public class HomeController : Controller { readonly log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType); public ActionResult Index() { log.Error("In Index "); return View(); } } when I run the appliction and go to this controller. Log4net does nothing. it doesn't create the files in that directory or anything. I have enabled internal debugging for lognet and I get no output errors in the console.

  • What can't I build in Silverlight?

    - by Refracted Paladin
    First, I know that Silverlight needs to be embedded in a website, usually an asp page. I understand I need a delivery boy. My question is this; What types of apps/projects are so filled with technological hurdles as to make them ridiculous to do in Silverlight versus ASP.net? I know that with perseverance and flexibility I can probably make EVERY app in Silverlight, in some version or another, but which ones would be blatantly simple in, say ASP.net(or even WPF) but quite complicated in Silverlight? Basically what I am asking is if there is any reason I shouldn't consider Silverlight my first stop for every problem, obvious exceptions not with standing(a service or console). For me specifically, at this point, I am only building in house apps.

  • Can't find controls in FormView.InsertItemTemplate even on DataBound event

    - by abatishchev
    I have FormView in my page markup: <asp:FormView ruanat="server" ID="FormView1" OnDataBound="FormView1_DataBound" DataSourceID="SqlDataSource1"> <InsertItemTemplate> <uc:UserControl1 runat="server" ID="ucUserControl1" /> </InsertItemTemplate> </asp:FormView> <asp:SqlDataSource runat="server" ID="SqlDataSource1" SelectCommand="EXEC someSP" /> It's code-behind: protected void FormView1_DataBound (object sender, EventArgs e) { var c1 = ((FormView)sender).FindControl("ucUserControl1"); // returns null var c2 = FormView1.FindControl("ucUserControl1"); // also returns null } In theory, I'm able to find control on FormView after it being data bound. But I'm not. Why?

  • Can't get NUnit to work in Visual Web Develper 2010 express.

    - by UkraineTrain
    First off I was wondering whether it's possible to implement a functionality with Nunit where each time a project is created in Visual Web Developer 2010 I get a dialog asking whether I want to create a unit test project for current application like I saw it happen in the older versions of Visual Web Developer. I've tried just about everything to get NUnit 2.5.5 to work in Visual Web Developer 2010. For example, in nunit.exe.config I added under configuration <startup> <requiredRuntime version="v4.0.30319" /> </startup> and under runtime: <loadFromRemoteSources enabled="true" /> I then tried to launch nunit-console.exe in order to specify in the command line the option /framework=net-4.0, but the console would appear and instantly disappear. It didn't help when I tried running it as an administrator. I've also tried using Nunit as an external tool inside the Visual Web Developer by creating a toolbar as described in the following link: http://www.marthijnvandenheuvel.com/2010/06/09/using-nunit-in-visual-studio-2010/. It shows up as an icon in the toolbar. I ran my project called ToyStore and then clicked Nunit icon in order to launch it and it gave me a "System.IO.FileNotFoundException:Assembly not found:ToyStore.dll". So, needless to say, I'm pretty lost and don't know what to do and would greatly appreciate any help in getting Nunit to work.

  • Visual Studio Web Application edit source while running like in Tomcat\Eclipse\Java

    - by Bryan Migliorisi
    In an ASP.NET Web Site project, I've always been able to make changes to the underlying C# code and simply refresh the page in the browser and my changes would be there instantly. I can do the same thing when working with Java and Eclipse - edit my Java source and refresh the page and my changes are there. I cannot do this in ASP.NET MVC though and it is a real downer - I have to stop the running process and make my changes, and then restart debugging. This is a huge waste of time. Am I doing it wrong? What is the best approach to ASP.NET MVC development?

  • How can I edit an exe's resources (File Description, Icon, etc.) using a command line utility?

    - by Coder7862396
    The whole story: I have created a fancy .NET program which has an installer created by the Visual Studio Installer (VSI). The VSI creates 2 files (setup.exe and MyProgramSetup.msi). I understand the reasons for both files being needed, however, I only want to distribute a SINGLE executable installer to users. I do not want them to see 2 files and have to choose between them. In order to do this I have merged the 2 files into a self-extracting archive using IExpress (as seen in this answer: http://stackoverflow.com/questions/535966/merge-msi-and-exe). This works well, however, the self-extracting archive that gets created has an ugly icon and confusing file info (the File Description is "Win32 Cabinet Self-Extractor" with 43 black spaces after it). I need to replace the icon with my custom one and change some of the file properties like "Description", "Company", etc. I would like to have this automatically done as a build step so having a program which is a command line/console utility would be great. I've searched for a while now and can only find one program which does exactly what I want (ResourceTuner Console: http://www.heaventools.com/command-line_resource_editor.htm) but it costs an arm and a leg and my budget is $0. Does anyone know a better way to achieve what I want, or know of a program which can replace an executable's resources without having to use a GUI? By the way, I have also tried "SiComponents Resource Builder 3" which can't even open the executable, and "Julien Audo's ResEdit" which just crashes when I execute the command: "resedit.exe -convert "Modified Resources.rc" "MyProgramSetup.exe"

  • What VS Projecttype for Model and Database?

    - by Tim
    Hello folks, i've just started a new asp.net project which could increase fastly(a small erp-system for our company). So i thought it would be a good idea to split at least the model from the view/controller(the asp.net project). Because it could be that i need to access some classes and the database from a windows app in future, i dicided to put the Model into its own Project. What Visual Studio 2005 Professional Projecttype is most suitable for this requirement and why? SqlServerProject (DB is MS Sql Server 2005 EP) Class Library Web Service Application Database project no separate Project/other(keep in mind VS 2005 has no ASP.NET MVC-Project) Thanks

  • Why doesn't a LinkButton work with a table as it's content?

    - by Telos
    Using ASP.NET 3.5, you can create a LinkButton then define content inside of it. It works fine if I have div tags or any kind of text or anything, but if I use a table the click doesn't actually post back for some reason. This should take you to google (you'll get an error there but it should still go) for instance: <asp:LinkButton ID="lbTest" PostBackUrl="http://www.google.com" runat="server"> <table> <tr> <td>Test</td> <td>col2</td> <td>col3</td> </tr> </table> </asp:LinkButton> I could work around it by building a "table" with divs I guess, but I hate formatting with divs.

  • Circular Reference exception with JSON Serialisation with MVC3 and EF4 CTP5w

    - by nakchak
    Hi I'm having problems with a circular reference when i try and serialise an object returned via EF4 CTP5. Im using the code first approach and simple poco's for my model. I have added [ScriptIgnore] attributes to any properties that provide a back references to an object and annoyingly every seems to work fine if i manually instantiate the poco's, i.e. they serialise to JSON fine, and the scriptignore attribute is acknowledged. However when i try and serialise an object returned from the DAL i get the circular reference exception "A circular reference was detected while serializing an object of type 'System.Data.Entity.DynamicProxies.xxxx'" I have tried several ways of retreiving the data but they all get stuck with this error: public JsonResult GetTimeSlot(int id) { TimeSlotDao tsDao = new TimeSlotDao(); TimeSlot ts = tsDao.GetById(id); return Json(ts); } The method below works slightly better as rather than the timeslot dynamic proxied object causing the circular refference its the appointment object. public JsonResult GetTimeSlot(int id) { TimeSlotDao tsDao = new TimeSlotDao(); var ts = from t in tsDao.GetQueryable() where t.Id == id select new {t.Id, t.StartTime, t.Available, t.Appointment}; return Json(ts); } Any ideas or solutions to this problem? Update I would prefer to use the out of the box serialiser if possible although Json.Net via nuget is ok as an alternative i would hope its possible to use it as I intended as well...

  • Is it possible to reference a linkbotton outside an update panel as the update trigger?

    - by Selase
    I have a page based on a master page and as such i can only see the content place holders i used in the master page showing up in the aspx pages based on the master page. the source code shown below: <%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="CaseAdmin.aspx.cs" Inherits="Prototype4.CaseAdmin" %> <%@PreviousPageType VirtualPath="~/Account/Login.aspx"%> <asp:Content ID="Content1" ContentPlaceHolderID="HeadContent" runat="server"> </asp:Content> <asp:Content ID="CaseRightNews" ContentPlaceHolderID="RightNewsItem" runat="server"> </asp:Content> <asp:Content ID="CaseLeftNav" ContentPlaceHolderID="LeftNavigation" runat="server"> <div style="margin-top:20px; margin-bottom:20px;"> <p class="actionButton"> <asp:LinkButton ID="OpenCaseLinkButton" runat="server" onclick="OpenCaseLinkButton_Click">Open Case</asp:LinkButton> </p> <p class="actionButton"><asp:LinkButton ID="RegisterExhibitLinkButton" runat="server" onclick="RegisterExhibitLinkButton_Click">Register Exhibit</asp:LinkButton> </p> </div> </asp:Content> <asp:Content ID="CaseMainContnt" ContentPlaceHolderID="MainContent" runat="server"> <asp:ScriptManager ID="ScriptManager" runat="server" /> <asp:UpdatePanel ID="CaseMainCntntUpdatePanel" UpdateMode="Conditional" runat="server"> <Triggers> <asp:AsyncPostBackTrigger ControlID="" eventname="Click"/> </Triggers> <ContentTemplate> <%--Some text here to inform user to click on the open case botton to display open case form--%> </ContentTemplate> </asp:UpdatePanel> <asp:UpdatePanel runat="server" id="UpdatePanel1" updatemode="Conditional"> <Triggers> <asp:AsyncPostBackTrigger ControlID="" eventname="Click"/> </Triggers> <ContentTemplate> <%--some text here to inform users to click on the add exhibit botton to display add exhibit form--%> </ContentTemplate> </asp:UpdatePanel> </asp:Content> the section of the entire page i wish to change upon update is the (this is the main content of the page). for this reason i placed the updatepanel inside the content place holder since it cant be sitting outside and not wrapped in a content place holder. However, the buttons that i wish to apply the trigger that fires the update to, are in another content place holder(). How can i possibly get those buttons to act as the trigger while changing only what appears in the main content area. Plus, i tried getting the updatepanel to work just so i could see if it does the update well but it turned out really bad. i added some linkbottons in the content template area and used them as the triggers for testing reasons. i tested and the changes took over the entire page in contrast to just appearing in the content area. I actually just wanted to load a form that is created in another asp. page into the main content area... I seriously need help with this... Every little help, detail and information is dearly appreciated... thanks so much in advance

  • How can I create an http handler to redirect all traffic to HTML pages?

    - by Eitan
    Our company would like to redirect all calls to html files on our server to a separate page. The html pages are NOT in an asp.net application. In order to do this, I've been writing and IIS Handler in asp.net. 1) Is this possible to add an IIS handler to redirect static content that isn't served by any asp.net engine, i.e. stand alone files on the server? 2) If it is possible, how do I do this? I created an http handler in a class library. In the app.config I added the handler to the and sections. I added the DLL to the GAC, I changed the html mapping to my custom IIS dll and nothing works. Is there a tutorial or explanation from A to B on how to do this? Thanks. E p.s. I'm using IIS 7.5

  • Shouldn’t GridView’s RowStyle-HorizontalAlign property overwrite CSS’s text-align property?

    - by AspOnMyNet
    a) As far as I know, GridView’s RowStyle-HorizontalAlign property should overwrite CSS’s text-align property, and thus text inside GridView's cells should be located on the left side of the cells, but is instead moved to the right side. Why is that? b) Similarly, RowStyle-Font-Bold should overwrite CSS’s font-weight property and thus fonts shouldn’t be in bold. But again, CSS’s property overwrites RowStyle’s Font-Bold property. Why? <div id="someClass"> <asp:GridView ID="gvwShowUsers" runat="server" > <RowStyle BackColor="#FFFBD6" ForeColor="#333333" Font-Bold="false" HorizontalAlign="Left" /> <Columns> <asp:BoundField DataField="UserName" HeaderText="UserName" /> </Columns> </asp:GridView> </div> CSS file: #someClass td { font-weight:bolder; text-align:right; } thanx

  • Problem with passing folder path string to web service function via jQuery.ajax

    - by the_V
    Hello, I need to perform asp.net web-service function call via jQuery and pass asp.net application path to it. That's the way I'm trying to do it (code is located within asp.net page, e.g. aspx file): var d = "{'str':'<%=System.DateTime.Now.ToString() %>', 'applicationPath':'<%=GetApplicationPath() %>'}"; $.ajax({ type: "POST", url: "http://localhost/testwebsite/TestWebService.asmx/Test", data: d, contentType: "application/json; charset=utf-8", dataType: "json", error: function (xhr, status, error) { var err = eval("(" + xhr.responseText + ")"); alert(err.Message); }, success: function (msg) { } }); That's what GetApplicationPath method looks like: protected string GetApplicationPath() { return HttpUtility.HtmlEncode(Request.PhysicalApplicationPath); } And here is a header of web-service function which I'm trying to call: public void Test(string str, string applicationPath) Function call works well, but applicationPath parameter doesn't passed correctly. When I debug it I see that backslashes are removed, function gets "C:ProjectsSamplesmytestwebsite" instead of "'C:\Projects\Samples\mytestwebsite\'". How can I overcome this?

There's one other thing I noticed. If I add partial class Article, when returning to articleRepository.cs I get error that 'Article' is an ambiguous reference between 'CMS.Models.Article' and 'CMS.Model.Article' Any thoughts on this one?

  • L2S DataContext out of synch: row not found or changed

    - by awrigley
    The Problem I am getting a number of errors that imply that the DataContext, or rather, the way I am using the DataContext is getting out of synch. The error occurs on db.SubmitChanges() where db is my DataContext instance. The error is: Row not found or changed. The problem only occurs intermitently, for example, adding a row then deleting it. If I stop the dev server and restart, the added row is there and I can delete it no problem. Ie, it seems that the problem is related to the DataContext losing track of the rows that have been added. IMPORTANT: Before anyone votes to close this thread, on the basis of it being a duplicate, I have checked the sql server profiler and there is no "Where 0 = 1" in the SQL. I have also recreated the dbml file, so am satisfied that the database schema is in synch with the schema represented by the dbml file. Ie, no cases of mismatched nullable/not nullable columns, etc. My Diagnosis (for what it is worth): It seems to be a problem related to how I am using the DataContext. I am new to MVC, Repositories and Services patterns, so suspect that I have wired things up wrong. The Setup Simple eLearning app in its early stages. Pupils need to be able to add and delete courses (Courses table) to their UserCourses. To do this, I have a service that gets a specific DataContext instance Dependency Injected into its constructor. Service Class Constructor: public class SqlPupilBlockService : IPupilBlockService { DataContext db; public SqlPupilBlockService(DataContext db) { this.db = db; CoursesRepository = new SqlRepository<Course>(db); UserCoursesRepository = new SqlRepository<UserCourse>(db); } // Etc, etc } The CoursesRepository and UserCoursesRepository are both private properties of the service class that are of Type IRepository (just a simple generic repository interface). Sql Respoitory Code: public class SqlRepository<T> : IRepository<T> where T : class { DataContext db; public SqlRepository(DataContext db) { this.db = db; } #region IRepository<T> Members public IQueryable<T> Query { get { return db.GetTable<T>(); } } public List<T> FetchAll() { return Query.ToList(); } public void Add(T entity) { db.GetTable<T>().InsertOnSubmit(entity); } public void Delete(T entity) { db.GetTable<T>().DeleteOnSubmit(entity); } public void Save() { db.SubmitChanges(); } #endregion } The two methods for adding and deleting UserCourses are: Service Methods for Adding and Deleting UserCourses: public void AddUserCourse(int courseId) { UserCourse uc = new UserCourse(); uc.IdCourse = courseId; uc.IdUser = UserId; uc.DateCreated = DateTime.Now; uc.DateAmended = DateTime.Now; uc.Role = "Pupil"; uc.CourseNotes = string.Empty; uc.ActiveStepIndex = 0; UserCoursesRepository.Add(uc); UserCoursesRepository.Save(); } public void DeleteUserCourse(int courseId) { var uc = (UserCoursesRepository.Query.Where(x => x.IdUser == UserId && x.IdCourse == courseId)).Single(); UserCoursesRepository.Delete(uc); UserCoursesRepository.Save(); } Ajax I am using Ajax via Ajax.BeginForm I don't think that is relevant. ASP.NET MVC 3 I am using mvc3, but don't think that is relevant: the errors are related to model code.

  • How can I hit my database with an AJAX call using javascript?

    - by tmedge
    I am pretty new at this stuff, so bear with me. I am using ASP.NET MVC. I have created an overlay to cover the page when someone clicks a button corresponding to a certain database entry. Because of this, ALL of my code for this functionality is in a .js file contained within my project. What I need to do is pull the info corresponding to my entry from the database itself using an AJAX call, and place that into my textboxes. Then, after the end-user has made the desired changes, I need to update that entry's values to match the input. I've been surfing the web for a while, and have failed to find an example that fits my needs effectively. Here is my code in my javascript file thus far: function editOverlay(picId) { //pull up an overlay $('body').append('<div class="overlay" />'); var $overlayClass = $('.overlay'); $overlayClass.append('<div class="dataModal" />'); var $data = $('.dataModal'); overlaySetup($overlayClass, $data); //set up form $data.append('<h1>Edit Picture</h1><br /><br />'); $data.append('Picture name: &nbsp;'); $data.append('<input class="picName" /> <br /><br /><br />'); $data.append('Relative url: &nbsp;'); $data.append('<input class="picRelURL" /> <br /><br /><br />'); $data.append('Description: &nbsp;'); $data.append('<textarea class="picDescription" /> <br /><br /><br />'); var $nameBox = $('.picName'); var $urlBox = $('.picRelURL'); var $descBox = $('.picDescription'); var pic = null; //this is where I need to pull the actual object from the db //var imgList = for (var temp in imgList) { if (temp.Id == picId) { pic= temp; } } /* $nameBox.attr('value', pic.Name); $urlBox.attr('value', pic.RelativeURL); $descBox.attr('value', pic.Description); */ //close buttons $data.append('<input type="button" value="Save Changes" class="saveButton" />'); $data.append('<input type="button" value="Cancel" class="cancelButton" />'); $('.saveButton').click(function() { /* pic.Name = $nameBox.attr('value'); pic.RelativeURL = $urlBox.attr('value'); pic.Description = $descBox.attr('value'); */ //make a call to my Save() method in my repository CloseOverlay(); }); $('.cancelButton').click(function() { CloseOverlay(); }); } The stuff I have commented out is what I need to accomplish and/or is not available until prior issues are resolved. Any and all advice is appreciated! Remember, I am VERY new to this stuff (two weeks, to be exact) and will probably need highly explicit instructions. BTW: overlaySetup() and CloseOverlay() are functions I have living someplace else. Thanks!

  • Create Views for object properties in model in MVC 3 application?

    - by Anders Svensson
    I have an Asp.Net MVC 3 application with a database "Consultants", accessed by EF. Now, the Consultant table in the db has a one-to-many relationship to several other tables for CV type information (work experience, etc). So a user should be able to fill in their name etc once, but should be able to add a number of "work experiences", and so on. But these foreign key tables are complex objects in the model, and when creating the Create View I only get the simple properties as editor fields. How do I go about designing the View or Views so that the complex objects can be filled in as well? I picture a View in my mind where the simple properties are simple fields, and then some sort of control where you can click "add work experience", and as many as needed would be added. But how would I do that and still utilize the model binding? In fact, I don't know how to go about it at all. (BTW, Program and Language stand for things like software experience in general, and natural language competence, not programming languages, in case you're wondering about the relationships there). Any ideas greatly appreciated! Here's the Create View created by the add View command by default: @{ ViewBag.Title = "Create"; } <h2>Create</h2> <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script> @using (Html.BeginForm()) { @Html.ValidationSummary(true) <fieldset> <legend>Consultant</legend> <div class="editor-label"> @Html.LabelFor(model => model.FirstName) </div> <div class="editor-field"> @Html.EditorFor(model => model.FirstName) @Html.ValidationMessageFor(model => model.FirstName) </div> <div class="editor-label"> @Html.LabelFor(model => model.LastName) </div> <div class="editor-field"> @Html.EditorFor(model => model.LastName) @Html.ValidationMessageFor(model => model.LastName) </div> <div class="editor-label"> @Html.LabelFor(model => model.UserName) </div> <div class="editor-field"> @Html.EditorFor(model => model.UserName) @Html.ValidationMessageFor(model => model.UserName) </div> <div class="editor-label"> @Html.LabelFor(model => model.Description) </div> <div class="editor-field"> @Html.EditorFor(model => model.Description) @Html.ValidationMessageFor(model => model.Description) </div> <p> <input type="submit" value="Create" /> </p> </fieldset> } <div> @Html.ActionLink("Back to List", "Index") </div> And here's the EF database diagram:

  • Java Deployment Ruleset not working

    - by adbertram
    I've created a Java Deployment Ruleset that looks like this: <ruleset version="1.0+"> <rule> <id location="http://hpfweb.mydomain.com/" /> <action permission="run" version="1.6.0_20" /> </rule> <rule> <id location="http://*.mydomain.com" /> <action permission="run" /> </rule> <rule> </ruleset> I've created a self-signed cert, added it into the keystore as well as Trusted Certification Authorities. I have an app at http://hpfweb.mydomain.com that requires Java v1.6.20 and will error out if any other version is attempted. When only this version is installed on the computer the application works. However, if a newer version is installed, it does not. As you can see, I've attempted to force the version to 1.6.0_20 in the ruleset. I've confirmed the deployment rule set is being applied successfully by going into the Java Control Panel -- Security and "view the active deployment rule set". It is exactly as you see here. I've also looked at the web source for the application and all references point to http://hpfweb* links. When the applet is launched I've brought up task manager and have confirmed the java.exe launched is coming from the jre6 directory. When the newer version is installed, I'm getting the error "accesscontrolexception - access denied (java.awt.AWTPermission.accessEventQueue".

  • Incorrect deployment of WSGI app to AWS using Elastic Beanstalk

    - by Dzmitry Zhaleznichenka
    cross-link to AWS forums I have developed a simple Python web service using WSGI and would like to deploy it to AWS cloud using Elastic Beanstalk. My problem is I cannot make all the options I specify in Elastic Beanstalk configuration to be correctly configured in the cloud. For deployment, I use Elastic Beanstalk CLI utility. I have run eb init command and set up the required parameters. After this, a directory named .elasticbeanstalk was created in my source tree. It has two config files that are used for deployment, namely config and optionsettings. The latter one among the other options contains the WSGI configuration that has to update /etc/httpd/conf.d/wsgi.conf at the instances. After some of my adjustments the file has the following settings: [aws:elasticbeanstalk:application:environment] DJANGO_SETTINGS_MODULE = PARAM1 = PARAM2 = PARAM4 = PARAM3 = PARAM5 = [aws:elasticbeanstalk:container:python] WSGIPath = handler.py NumProcesses = 2 StaticFiles = /static= NumThreads = 10 [aws:elasticbeanstalk:container:python:staticfiles] /static = static/ [aws:elasticbeanstalk:hostmanager] LogPublicationControl = false [aws:autoscaling:launchconfiguration] InstanceType = t1.micro EC2KeyName = zmicier-aws [aws:elasticbeanstalk:application] Application Healthcheck URL = [aws:autoscaling:asg] MaxSize = 10 MinSize = 1 Custom Availability Zones = [aws:elasticbeanstalk:monitoring] Automatically Terminate Unhealthy Instances = true [aws:elasticbeanstalk:sns:topics] Notification Endpoint = Notification Protocol = email It turns out that not all of these options are considered when I start the environment or update it. Thus, when I update NumThreads or NumProcesses, the respective parameters get changed in wsgi.conf as expected. But whatever I write to the WSGIPath and StaticFiles parameters, I'm not able to automatically change the respective values of wsgi.conf, they remain Alias /static /opt/python/current/app/ WSGIScriptAlias / /opt/python/current/app/application.py which drives me nuts. Moreover, when I deploy my application using git aws.push and having the following contents of .ebextensions/python.config file, neither of options I specify in it affects the deployment. option_settings: - namespace: aws:elasticbeanstalk:container:python option_name: WSGIPath value: mysite/wsgi.py - namespace: aws:elasticbeanstalk:container:python option_name: NumProcesses value: 5 - namespace: aws:elasticbeanstalk:container:python option_name: NumThreads value: 25 - namespace: aws:elasticbeanstalk:container:python:staticfiles option_name: /static/ value: app/static/ I wonder what I should do to force AWS use all the parameters I specify in the configuration, namely the WSGI Path and path to my static data.

  • Barriers to IPv6 deployment: addressing

    - by sysadmin1138
    There are several things that are keeping IPv6 deployment from being a topic of active discussion here at my work. There are the usual technical issues, but one non-technical one appears to be a major stumbling block on the path to actually getting a deployment project going. Addresses, memorizing of. Specifically, IPv4 addresses are comprehensible, and IPv6 addresses just look like a big long string of hex. The human mind has real trouble memorizing lists of more than 7-8 items, and an IPv4 address (192.168.231.148) has four items in it which makes it easy for us to memorize. A fully populated IPv6 address has not only 8 sections, but each section has 4 hex digits in it. IPv6 addresses were not designed for memorization. To the technician who knows that the DNS server is at 192.168.42.42 (or more likely "42.42", since the company prefix is likely memorized), the idea of memorizing an IPv6 address fills them with dread. Which in turn makes them much less enthusiastic about participating in an IPv6 deployment project. Because of how our network works we're not fully dynamic in terms of v4 addressing. We have several to many subnets that are entirely statically assigned for a variety of reasons, chief among them being that the overhead of static DHCP assignments is perceived as being too great. Also, some devices still aren't smart enough to pull DNS addresses out of DHCP while also having a static assignment, and therefore require manually configured DNS settings. Therefore, some v6 address memorization will have to be done. We're not under any mandate to get v6 out the door, so we don't have pressure from the top. However, it is time to start prepping our infrastructure to handle IPv6 even if we don't convert wholesale. For those of you who have been in IPv6-land for a while, what short-cut methods do you use to discuss or keep track of subnets and specific/critical IP addresses? If I can help reduce some of the dread surrounding IPv6 we might get the project going.
