• Display Image in Crystal reports Using URL

  - by Shantanu Gupta

  I want to show image in a crystal report. Scenario is something like this. I have a database where my path of an image is persisting. eg ftp://Images/1.jpg Now i want to repeat this image in a crystal report. When i fills my datatable it shows me complete url. When i displays this field in GridView i uses imageBox to display my image and it works for me very fine. But when i tries to do the same with crystal reports, it starts me showing image path as it is. Now here instead of path i want an image to be displayed.

• How to handle missing files on MVC

  - by kaivalya

  What is your preferred way to handle hits to files that does not exist on your MVC app. I have couple of web apps runing with MVC and they are constantly getting hits for files folders etc. that does not exist in the app structure. Apps are throwing exception: The controller for path could not be found or it does not implement IController I am trying to find out the best way to handle this. I have 3 global routes on my global.asax file (see below) and at this point I am happy with that simple definition. I know if I added route definition for all controllers then I can add a definition to ignore the rest and handle these hits but if it will be possible to solve this problem without it, I do not want to add route definitions for each controller which I believe will flood the route definitions and also add a layer of maintenance which I don't like. //Aggregates 2nd level routes.MapRoute( "AggregateLevel2", "{controller}/{action}/{id}/{childid}/{childidlevel2}", new { controller = "Home", action = "Index", id = "", childid = "", childidlevel2 = "" } ); //Aggregates 1st level routes.MapRoute( "AggregateLevel1", "{controller}/{action}/{id}/{childid}", new { controller = "Home", action = "Index", id = "", childid = "" } ); routes.MapRoute( "Default", "{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = "" } );

• Need Help on a custom HTML Helper

  - by LeeHull

  I'm trying to create a custom HTML Helper to help simplify my masterpages menu, however it is not rendering on the HTML when I use it.. I'm thinking I will need to create a partial view, any ideas? I did this.. public static string CreateAdminMenuLink(this HtmlHelper helper, string caption, string link) { var lnk = TagBuilder("a"); lnk.SetInnerText(caption); lnk.MergeAttribute("href", target); return lnk.ToString(TagRenderMode.SelfClosing); } Now in my View, i have <% Html.CreateAdminMenuLink("Home", "~/Page/Home"); %> but when I look at the source, its empty.. tried adding <% using (Html.BeginForm()) % and it adds a form.. but the link still doesnt come up.. debugged and the string works when i look at the watch, but does not render.. Any ideas?

• MVC Pattern Clarification

  - by Amutha

  Just I started learning MVC pattern,ofcourse i am learning it from Microsoft's website.Just i want to gather quiz information from the experts. My understanding is (correct me then and there) 1 ) MVC does not support server side events ,but supports client side events.if it supports client side events,i need html page with jQuery/Javascript (view),but most of the example i absorbed is to display the information(model) in view ,i did not see any client side event handling happens in view. 2) Except ViewState and controlState,MVC supports Sessions,Application State management,Cache management. 3) When request goes to MVC engine ,the routing module routes the request that is picked up by the controller.The controller in executes the appropriate action and return the appropriate view.

• MVC2: "File not found" after view is painted

  - by Dave Hanna

  This is wierd. First, I'm building a site based on someone else's framework (Piers Lawson: Creating a RESTful Web Service using MVC ), so I'm not entirely sure what's going on under the covers. But when I run it in VS 2010 by pressing F5, it brings up the Home page, and THEN traps an error in Application_Error. The error is "File does not exist" exception. But I have no idea what file it's looking for. Where does flow control go after the View is finished displaying? How can I break to find out what it's looking for?

• How to efficiently save changes made in UI/main thread with Core Data?

  - by Jaanus

  So, there have been several posts here about importing and saving data from an external data source into Core Data. Apple documents a reasonable pattern for this: "import and save on background thread, merge saved objects to main thread." All fine and good. I have a related but different problem: the user is modifying data in the UI and main thread, and thus modifies state of some objects in the managed object context (MOC). I would like to save these changes from time to time. What is a good way to do that? Now, you could say that I could do the same: create a background thread with its own MOC and pass the changed objectID-s there. The catch-22 for me with this is that an object's ID changes when it is saved, and I cannot guarantee the order of things happening. I may end up passing a different objectID into the background thread for the same object, based on whether the object has been previously saved or not, and I don't know if Core Data can resolve this and see that different objectID-s are pointing to the same object and not create duplicates for me. (I could test this, but I'm lazywebbing with this question first.) One thought I had: I could always do MOC saves on a background thread, and queue them up with operationqueue, so that there is always only one save in progress. I would not create a new MOC, I would just use the same MOC as in main thread. Now, this is not thread safe and when someone modifies the MOC in main thread while it is being saved in background thread, the results will probably be catastrophic. But, minus the thread safety, you can see what kind of solution I'd wish for. To be clear, the problem I need to fix is that if I just do the save in main thread, it blocks the UI for an unacceptably long period of time, I want to move the save to background thread. So, questions: what about the reasoning of an object ID changing during saving, and Core Data being able to resolve them to the same object? Would this be the right way of addressing this problem? any other good ways of doing this?

• List getting cleared every button click inside Update Panel?

  - by sah302

  No this isn't a copy of this question: http://stackoverflow.com/questions/654423/button-in-update-panel-is-doing-a-full-postback I've got a drop down inside an update panel, and I am trying to get it to allow the person using the page to add users to a list that is bound to a gridview. The list is a global variable, and on page_load I set that to the gridview's datasource and databind it. However, anytime I click the 'add a user' button, or the button to remove the user from the list. It appears like it is doing a full post back even though all these elements are inside the update Panel. Code Behind: Public accomplishmentTypeDao As New AccomplishmentTypeDao() Public accomplishmentDao As New AccomplishmentDao() Public userDao As New UserDao() Public facultyDictionary As New Dictionary(Of Guid, String) Public facultyList As New List(Of User) Public associatedFaculty As New List(Of User) Public facultyId As New Guid Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Page.Title = "Add a New Faculty Accomplishment" ddlAccomplishmentType.DataSource = accomplishmentTypeDao.getEntireTable() ddlAccomplishmentType.DataTextField = "Name" ddlAccomplishmentType.DataValueField = "Id" ddlAccomplishmentType.DataBind() facultyList = userDao.getListOfUsersByUserGroupName("Faculty") For Each faculty As User In facultyList facultyDictionary.Add(faculty.Id, faculty.LastName & ", " & faculty.FirstName) Next If Not Page.IsPostBack Then ddlFacultyList.DataSource = facultyDictionary ddlFacultyList.DataTextField = "Value" ddlFacultyList.DataValueField = "Key" ddlFacultyList.DataBind() End If gvAssociatedUsers.DataSource = associatedFaculty gvAssociatedUsers.DataBind() End Sub Protected Sub deleteUser(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.CommandEventArgs) facultyId = New Guid(e.CommandArgument.ToString()) associatedFaculty.Remove(associatedFaculty.Find(Function(user) user.Id = facultyId)) gvAssociatedUsers.DataBind() upAssociatedFaculty.Update() End Sub Protected Sub btnAddUser_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnAddUser.Click facultyId = New Guid(ddlFacultyList.SelectedValue) associatedFaculty.Add(facultyList.Find(Function(user) user.Id = facultyId)) gvAssociatedUsers.DataBind() upAssociatedFaculty.Update() End Sub Markup: <asp:ScriptManager ID="ScriptManager1" runat="server"> </asp:ScriptManager> <asp:UpdatePanel ID="upAssociatedFaculty" runat="server" UpdateMode="Conditional"> <ContentTemplate> <p><b>Created By:</b> <asp:Label ID="lblCreatedBy" runat="server"></asp:Label></p> <p><b>Accomplishment Type: </b><asp:DropDownList ID="ddlAccomplishmentType" runat="server"></asp:DropDownList></p> <p><b>Accomplishment Applies To: </b><asp:DropDownList ID="ddlFacultyList" runat="server"></asp:DropDownList> &nbsp;<asp:Button ID="btnAddUser" runat="server" Text="Add Faculty" /></p> <p> <asp:GridView ID="gvAssociatedUsers" runat="server" AutoGenerateColumns="false" GridLines="None" ShowHeader="false"> <Columns> <asp:BoundField DataField="Id" HeaderText="Id" Visible="False" /> <asp:TemplateField ShowHeader="False"> <ItemTemplate> <span style="margin-left: 15px;"> <p><%#Eval("LastName")%>, <%#Eval("FirstName")%> <asp:Button ID="btnUnassignUser" runat="server" CausesValidation="false" CommandArgument='<%# Eval("Id") %>' CommandName="Delete" OnCommand="deleteUser" Text='Remove' /></p> </span> </ItemTemplate> </asp:TemplateField> </Columns> <EmptyDataTemplate> <em>There are currently no faculty associated with this accomplishment.</em> </EmptyDataTemplate> </asp:GridView> </p> </ContentTemplate> </asp:UpdatePanel> Now I thought the point of an update panel was to be able to update things inside of it without doing a full post_back and reloading the page. So if that's the case, why is it calling page_load everytime I click the buttons? I ran this code and debug and I see that even before any of the code associated with button press fires, page_load runs again. I tried putting the gvAssociatedUser.Datasource = associatedFaculty and the line below inside the Page.IsPostBack check, that prevented the page from working. I tried every combination of settings of the update panel for ChildrenAsTriggers and UpdateMode, and none of them worked. I know this is something simple, but all the combinations I've tried won't get it to work. How can I make this thing work? Edited: It wasn't causing a full postback so I was wrong as to the cause. I thought the page was doing a full post back thus resetting my associatedFaculty list global variable, but it isn't doing a full postback. The issue I am having is everytime I click btnAddUser it will add one element to the associatedFaculty list and thus bound to gvAssociatedusers. This works the first time, but the second time I click it, it overwrites the first element. So it appears like my associatedFaculty list is getting reset each time I click the button?

• MVC2 Model Binding Enumerables?

  - by blesh

  Okay, so I'm fairly new to model binding in MVC, really, and my question is this: If I have a model with an IEnumerable property, how do I use the HtmlHelper with that so I can submit to an Action that takes that model type. Model Example: public class FooModel { public IEnumerable<SubFoo> SubFoos { get; set; } } public class SubFoo { public string Omg { get; set; } public string Wee { get; set; } } View Snip: <%foreach(var subFoo in Model.SubFoo) { %> <label><%:subfoo.Omg %></label> <%=Html.TextBox("OH_NO_I'M_LOST") %> <%} %>

• PreApplicationStartMethod Attribute causes exception

  - by Joop

  Strange thing happening to me with the PreApplicationStartMethod Attribute. I did implement it in my latest project. In the AssemblyInfo.cs I have the following line: [assembly: PreApplicationStartMethod(typeof(MyAssembly.Initializer), "Initialize")] The Type and method look like this: namespace MyAssembly { public static class Initializer { public static void Initialize() { TranslationKeys.Initialize(); } } } When I rebuild my application and load it in the browser I get the following error: The method specified by the PreApplicationStartMethodAttribute on assembly 'MyWebApp, Version=0.0.1.0, Culture=neutral, PublicKeyToken=null' cannot be resolved. Type: 'MyAssembly.Initializer', MethodName: 'Initialize'. Verify that the type is public and the method is public and static (Shared in Visual Basic). I really have no idea what the problem is.

• MVC routing - why does my request not match the route?

  - by Anders Juul

  Hi all, I'm making a request that I thought would be caught by my route, but there is no match. What am I doing wrong? Any comments appreciated, Anders, Denmark -- Url : EventReponse/ComingAdmin/386/01e71c45-cb67-4711-a51f-df5fcb54bb8b Expected match: routes.MapRoute( "Editing event responses for other user", // Route name "EventResponse/{action}/{eventId}/userId", // URL with parameters new {controller = "EventResponse", action = "ComingAdmin"} // Parameter defaults ); Desired controller (but I guess this does not come into play): public class EventResponseController : ControllerBase { (...) public ActionResult ComingAdmin(int eventId, Guid userId) { return RegisterEventResponse(eventId, AttendanceStatus.Coming, userId); } }

• MVC: capture route url's and pass them to javascript function

  - by Tim Geerts

  Short:Is there a way to have a route-definition that will pass the "CONTROLLER/ACTION" string value to a javascript function in stead of actually going straight for the controller action? More:I have a masterpage which contains the navigation of the site. Now, all the pages need this navigation wrapped around it at all times, but because I didn't want the navigation to constantly load with each pagecall, I changed all my pages to partialviews. These partial views are loaded via the JQuery.Load() method whenever a menu item is clicked in the navigation. This all worked very good, up till now because I noticed it's also a requirement of the website to be able to link directly to page X, rather then default.aspx. So, as an example:The main page is my "default.aspx" page, this utilizes my master page with the nagivation around it. And each call to a new page uses a javascript function that loads that particular partial view inside a div that is known in my masterpage. So, the url never changes away from "default.aspx", but my content changes seemlesly. The problem is, those url's also need to be available when typed directly into the address bar. But, they're partial views, so loading them directly from the address bar makes them display without any masterpages around them. Therefore my question if it might be possible to capture the route typed into the address bar and pass that on to my javascript function that will load that route in the content div. (I hope I explained it ok enough, if not, feel free to ask more information)

• Top 3 reasons not to develop a "blog system" that generates aspx files on the fly.

  - by klausbyskov

  In this question the OP implies that he wants to base the blog system he is developing on automatic creation of .aspx files, one for each new blog entry. In my answer to his question (which is related to something else), I told him that I would discourage him from using such an approach, but without giving any real reasons. He is now wanting reasons why it is not a good idea, and I'm using this question to see if the community can come up with a compelling enough list of reasons for him to use another approach, such as one using a dbms, code-reuse, url-rewriting, MVC, and what not.

• Join collection of objects into comma-separated string

  - by Helen Toomik

  In many places in our code we have collections of objects, from which we need to create a comma-separated list. The type of collection varies: it may be a DataTable from which we need a certain column, or a List<Customer>, etc. Now we loop through the collection and use string concatenation, for example: string text = ""; string separator = ""; foreach (DataRow row in table.Rows) { text += separator + row["title"]; separator = ", "; } Is there a better pattern for this? Ideally I would like an approach we could reuse by just sending in a function to get the right field/property/column from each object.

• Problem with order by in LINQ

  - by vikitor

  Hi, I'm passing from the controller an array generated by the next code: public ActionResult GetClasses(bool ajax, string kingdom) { int _kingdom = _taxon.getKingdom(kingdom); var query = (from c in vwAnimalsTaxon.All() orderby c.ClaName select new { taxRecID = c.ClaRecID, taxName = c.ClaName }).Distinct(); return Json(query, JsonRequestBehavior.AllowGet); } The query List should be ordered, but it doesn't work, I get the names of the classes ordered wrong in the array, because I've seen it debugging that the names are not ordered.The view is just a dropdownbox loaded automatically, so I'm almost sure the problem is with the action. Do you see anything wrong?Am I missing something?

• Dice face value recognition

  - by Jakob Gade

  I’m trying to build a simple application that will recognize the values of two 6-sided dice. I’m looking for some general pointers, or maybe even an open source project. The two dice will be black and white, with white and black pips respectively. Their distance to the camera will always be the same, but their position on the playing surface will be random. (not the best example, the surface will be a different color and the shadows will be gone) I have no prior experience with developing this kind of recognition software, but I would assume the trick is to first isolate the faces by searching for the square profile with a dominating white or black color (the rest of the image, i.e. the table/playing surface, will in distinctly different colors), and then isolate the pips for the count. Shadows will be eliminated by top down lighting. I’m hoping the described scenario is so simple (read: common) it may even be used as an “introductory exercise” for developers working on OCR technologies or similar computer vision challenges.

• Custom XML Serialization, how to write custom root element?

  - by Beta033

  I'm probably just doing this wrong, i know. i'm using custom serialization and when the xml is generated it's putting the class name as the root element Example: <MyClassName> <MyIntendedRootNode> <ObjectType> <Property1/> <Property2/> ... I'm inoking the serialization by calling xmlserializer.Serialize(writer,Me) so i'm sure that has something to do with it. I've tried putting XMLRoot onto the class, but i think as vb is compiling this partial class with it's aspx page, it's either overwriting this property or ignoring it entirely. ideally i'd like to just tell it to either throw away everything it has and use a different root element. Anybody else do this except me? Thanks

• JQuery datepicker not working

  I'm completely new to JQuery and MVC. I'm working on a pet project that uses both to learn them and I've hit my first snag. I have a date field and I want to add the JQuery datepicker to the UI. Here is what I have done: Added <script src="../../Scripts/jquery-1.3.2.min.js" type="text/javascript"></script> to the site.master Inside my Create.aspx (View), I have <asp:Content ID="Create" ContentPlaceHolderID="MainContent" runat="server"> <h2> Create a Task</h2> <% Html.RenderPartial("TaskForm"); %> </asp:Content> and inside "TaskForm" (a user control) I have: <label for="dDueDate"> Due Date</label> <%= Html.TextBox("dDueDate",(Model.Task.TaskID > 0 ? string.Format("{0:g}",Model.Task.DueDate) : DateTime.Today.ToString("MM/dd/yyyy"))) %> <script type="text/javascript"> $(document).ready(function() { $("#dDueDate").datepicker(); }); </script> As you can see, the above checks to see if a task has an id 0 (we're not creating a new one) if it does, it uses the date on the task, if not it defaults to today. I would expect the datepicker UI element to show up, but instead I get: "Microsoft JScript runtime error: Object doesn't support this property or method" on the $("#dDueDate").datepicker(); Ideas? It is probably a very simple mistake, so don't over-analyze. As I said, this is the first time I've dealt with MVC or JQuery so I'm lost as to where to start.
