  • Questions every good .NET developer should be able to answer?

    - by splattne
    My company is about to hire .NET developers. We work on a variety of .NET platforms: ASP.NET, Compact Framework, Windowsforms, Web Services. I'd like to compile a list/catalog of good questions, a kind of minimum standard to see if the applicants are experienced. So, my question is: What questions do you think should a good .NET programmer be able to respond? I'd also see it as a checklist for myself, in order to see where my own deficits are (there are many...). *UPDATE: It want to make clear that we're not testing only for .NET knowledge, and that problem solving capabilities and general programming skills are even more important to us.

  • .NET TCP socket with session

    - by Zé Carlos
    Is there any way of dealing with sessions with sockets in C#? Example of my problem: I have a server with a socket listening on port 5672. TcpListener socket = new TcpListener(localAddr, 5672); socket.Start(); Console.Write("Waiting for a connection... "); // Perform a blocking call to accept requests. TcpClient client = socket.AcceptTcpClient(); Console.WriteLine("Connected to client!"); And i have two clients that will send one byte. Client A send 0x1 and client B send 0x2. From the server side, i read this data like this: Byte[] bytes = new Byte[256]; String data = null; NetworkStream stream = client.GetStream(); while ((stream.Read(bytes, 0, bytes.Length)) != 0) { byte[] answer = new ... stream.Write(answer , 0, answer.Length); } Then client A sends 0x11. I need a way to know that this client is the same that sent "0x1" before.

  • Passing more than one argument in asp.net button in gridview

    - by MarceloRamires
    I have a TemplateField column in a gridview with a button inside of it. There is NO key value (surely that was not designed by me) , but in the other hand there aren't redundancies when comparing each single column, because they are events, and there is "starting date" and "ending date" of something that could not happen twice at the same time. I've already figured selecting with these values and all, but I just want the button to pass about five arguments to a given function. I've tested: <asp:Button CommandArgument='<%# Eval("day")%>' ID="Button2" runat="server" Text="Button" /> And it works properly, the day of the clicked row is passed, and could be retrieved through: e.CommandArgument.ToString(); in the GridView_RowCommand handler. How do I pass more than one argument? I've thought about concatenating with a separating character (wouldn't be that bad) but besides not knowing how to do it yet (didn't want to invest in a poor solution) I want a smarter one.

  • .NET: Problems creating email attachment from MemoryStream.

    - by David
    Hi all I'm using the following method to create an attachment from a MemoryStream: public void AddAttachment(Stream stream, string filename, string mimeType) { byte[] buffer = ((MemoryStream) stream).GetBuffer(); Attachment attachment = new Attachment(stream, filename, mimeType); _mail.Attachments.Add(attachment); } Note that the first line is not necessary isn't necessary for the attachment functionality, it's just useful to have the byte[] handy during debugging so that I can see how big it is. (It generally has around 80,000 elements.) The code runs fine and the email is sent. When Outlook receives the email, in the Inbox it displays the attachment symbol, but when you go into the email the attachment isn't there. Unfortunately I don't have access to the mail server to find out more about the email, e.g. what the attachment looks like, its size etc. Can anyone suggest what properties of the MemoryStream argument might tell me if it is in some way invalid for attachment? Or think of anything else I might try? Thank you. David

  • ASP.NET custom routes for simple requirements management tool

    - by Andrew
    I am implementing a very simple requirements management tool. I want the URLs to look like this: Shows home page for "Project One": http://projectmanager/Project/Project%20One Shows a list of requirements being worked on for "Project One" http://projectmanager/Project/Project%20One/Requirements Shows requirement 1 for "Project One" http://projectmanager/Project/Project%20One/Requirement/1 How could I set up routes so that http://projectmanager/Project/Project%20One is handled by the project controller http://projectmanager/Project/Project%20One/Requirements and http://projectmanager/Project/Project%20One/Requirements/1 is handled by the requirements controller. Is it even possible?

  • asp.net mvc ajax form helper/post additional data

    - by Jopache
    I would like to use the ajax helper to create ajax requests that send additional, dynamic data with the post (for example, get the last element with class = blogCommentDateTime and send the value of that last one to the controller which will return only blog comments after it). I have successfully done so with the help of jQuery Form plugin like so: $(document).ready(function () { $("#addCommentForm").submit(function () { var lastCommentDate = $(".CommentDateHidden:last").val(); var lastCommentData = { lastCommentDateTicks: lastCommentDate }; var formSubmitParams = { data: lastCommentData, success: AddCommentResponseHandler } $("#addCommentForm").ajaxSubmit(formSubmitParams); return false; }); This form was created with html.beginform() method. I am wondering if there is an easy way to do this using the ajax.beginform() helper? When I try to use the same code but replace html.beginform() with ajax.beginform(), when i try to submit the form, I am issuing 2 posts (which is understandable, one being taken care of by the helper, the other one by me with the JS above. I can't create 2 requests, so this option is out) I tried getting rid of the return false and changing ajaxSubmit() to ajaxForm() so that it would only "prepare" the form, and this leads in only one post, but it does not include the extra parameter that I defined, so this is worthless as well. I then tried keeping the ajaxForm() but calling that whenever the submit button on the form gets clicked rather than when the form gets submitted (I guess this is almost the same thing) and that results in 2 posts also. The biggest reason I am asking this question is that I have run in to some issues with the javascript above and using mvc validation provided by the mvc framework (which i will set up another question for) and would like to know this so I can dive further in to my validation issue.

  • Asp.net mvc - trying to display images pulled from db \

    - by Trey Carroll
    //Inherits="System.Web.Mvc.ViewPage<FilmFestWeb.Models.ListVideosViewModel>" <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>ListVideos</h2> <% foreach(BusinessObjects.Video vid in Model.VideoList){%> <div class="videoBox"> <%= Html.Encode(vid.Name) %> <img src="<%= vid.ThumbnailImage %>" /> </div> <%} %> </asp:Content> //ListVideosViewModel public class ListVideosViewModel { public IList<Video> VideoList { get; set; } } //Video public class Video { public long VideoId { get; set; } public long TeamId { get; set; } public string Name { get; set; } public string Tags { get; set; } public string TeamMembers { get; set; } public string TranscriptFileName { get; set; } public string VideoFileName { get; set; } public int TotalNumRatings { get; set; } public int CumulativeTotalScore { get; set; } public string VideoUri { get; set; } public Image ThumbnailImage { get; set; } } I am getting the "red x" that I usually associate with image file not found. I have verified that my database table shows after the stored proc that uploads the image executes. Any insight or advice would be greatly appreciated.

  • Updating a DLL in a Production ASP.NET Web Site bin folder

    - by Josh Stodola
    I want to update a class library (a single DLL file) in a production web application. This web app is pre-compiled (published). I read an answer on StackOverflow (sorry, can't seem to find it anymore because the Search function does not work very well), that led me to believe that I could just paste the new DLL in the bin folder and it would be picked up without problems (this would cause the WP to recycle, which is fine with me because we do not use InProc session state). However, when I tried this, my site blows up and gives a FileLoadException saying that the assembly manifest definition does not match the assembly reference. What in the world is this?! Updating the DLL in Visual Studio and re-deploying the entire site works just fine, but it is a huge pain in the rear. What is the point of having a separate DLL if you have to re-deploy the entire site to implement any changes? Here's the question: How can I update a DLL on a production web site without breaking the app and without re-deploying all of the files?

  • Setting the ASP.NET version via MSBUILD

    - by dovholuk
    I am trying to create a new website on a remote server via msbuild (I like to call it "msdeploy"). I've downloaded and used the SDC tasks, the MSBuildExtension tasks and the MSBuildCommunity tasks but I simply can't get it right. I figure that WebDirectorySetting (from MSBuild.Community.Tasks.IIS) is my best bet but I can't find the right SettingName to pass. I'd like to use some sort of MSBuild task to accomplish this but maybe it just doesn't exist. Custom VBS or WMI are my last resort... Thanks

  • How to structure controller to sort multiple criteria asp.net mvc

    - by Solomon
    Hi, What's the best way to set up a controller to sort by many (possibly null) criteria? Say for example, I was building a site that sold cars. My CarController has a function Index() which returns an IList of cars to the view, and details on each car are rendered with a partial view. What's the best way to structure this? Especially if there are a lot of criteria: Car Type (aka SUV), Car Brand, Car Model, Car Year, Car Price, Car Color, bool IsNew, or if I want to sort by closest to me etc... I'm using NHibernate as my ORM. Should I have just a ton of possible NHibernate queries and figure out which one to choose based on if/then's in the controller? Or is there a simpler way. Thanks so much for the help.

  • What is the header of an array in .NET

    Hi all, I have a little bit seen the representation of an array in memory with Windbg and SOS plugin. Here it is the c# : class myobj{ public int[] arr; } class Program{ static void Main(string[] args){ myobj o = new myobj(); o.arr = new int[7]; o.arr[0] = 0xFFFFFF; o.arr[1] = 0xFFFFFF; o.arr[2] = 0xFFFFFF; o.arr[3] = 0xFFFFFF; o.arr[4] = 0xFFFFFF; } } I break at final of Main, and I observ : 0:000> !clrstack -l OS Thread Id: 0xc3c (0) ESP EIP 0015f0cc 0043d1cf test.Program.Main(System.String[]) LOCALS: 0x0015f0d8 = 0x018a2f58 0:000 !do 0x018a2f58 Name: test.myobj MethodTable: 0026309c EEClass: 00261380 Size: 12(0xc) bytes (C:\Users\admin\Documents\Visual Studio 2008\Projects\test\test\bin\Debug\test.exe) Fields: MT Field Offset Type VT Attr Value Name 01324530 4000001 4 System.Int32[] 0 instance 018a2f64 tab 0:000 dd 018a2f64 018a2f64 01324530 00000007 00ffffff 00ffffff 018a2f74 00ffffff 00ffffff 00ffffff 00000000 018a2f84 00000000 00000000 00000000 00000000 018a2f94 00000000 00000000 00000000 00000000 018a2fa4 00000000 00000000 00000000 00000000 018a2fb4 00000000 00000000 00000000 00000000 018a2fc4 00000000 00000000 00000000 00000000 018a2fd4 00000000 00000000 00000000 00000000 I can see that the header contains the size of the array (00000007) but my question is : what is the value 01324530 ?

  • ASP.NET MVC Populating a DropDownList with a value from the view

    - by lomaxx
    In my controller I have this: ViewData["maskList"] = new SelectList(equipmentRepository.GetMasks(), "Id", "DisplayName"); and then I bind it to my view using <div each="var nfa in mfa.NasalFittingAssessment"> ${Html.DropDownList("NasalMaskTypeId", ViewData["maskList"] as IEnumerable<System.Web.Mvc.SelectListItem>, new { class = "ddl" })} </div> Note that I'm using the spark view engine so this DropDownList is getting rendered to the page via a loop. This means that the selected value of the dropdown list will change on each iteration of the loop. What I can't work out is how to pass in the value I want to set the DropDownList to based on the value that is currently being rendered to the screen.

  • ASP.NET MVC does not add ModelError when invoking from unit test

    - by Tomas Lycken
    I have a model item public class EntryInputModel { ... [Required(ErrorMessage = "Description is required.", AllowEmptyStrings = false)] public virtual string Description { get; set; } } and a controller action public ActionResult Add([Bind(Exclude = "Id")] EntryInputModel newEntry) { if (ModelState.IsValid) { var entry = Mapper.Map<EntryInputModel, Entry>(newEntry); repository.Add(entry); unitOfWork.SaveChanges(); return RedirectToAction("Details", new { id = entry.Id }); } return RedirectToAction("Create"); } When I create an EntryInputModel in a unit test, set the Description property to null and pass it to the action method, I still get ModelState.IsValid == true, even though I have debugged and verified that newEntry.Description == null. Why doesn't this work?

  • Deployment Setup (.Net) - Search target machine -> Registry search (64 bit)

    - by Joonas Kirsebom
    I have a windows installer project which installs some software (winform, service, mce addin). During the installation I need to search the machine for a registry key. This is done with with the "Launch Condition" - "Add Registry Search" (Deployment Project). I have filled out all the properties right, and checked against the regestry that the value actually can be found. The problem is that the "Registry Search" searches in the x86 part of the registry (HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\...) although my system is a x64 and the deployment setup is also set to x64. Does anyone know how to force the "Registry Search" to search the x64 registry? Or know about a workaround? The weird thing about this, is that Registry setting in the deployment setup is writing to the right registry (x64). My idea is that the "Registry Search" program is only developed to the x86 architecture, and therefore can't read the right registry. I found this article from microsoft, so it seams that they know about this problem. https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=110105&wa=wsignin1.0#details My system is: Windows 7 64bit Visual Studio 2008

  • Storing links to internal content pages in ASP.NET MVC

    - by mare
    I'm using a route like this routes.MapRoute( "PageBySlug", RouteType.Regular, "{slug}", new {controller = "Page", action = "Display", slug = "Default"}, null ); to map request to ~/Some-Page-Slug to ~/Page/Display/Some-Page-Slug. When adding content, user can choose to link to existing pages to create references and I then store those links in this format in the datastore: "/Some-Page-Slug". When I run the app in Cassini and pull the link out from datastore and attach it to A tag it looks like this http://localhost:93229/Some-Page-Slug and this link works. But when running the application in virtual directory under some website in IIS, the attached link generates this URL http://localhost/Some-Page-Slug, when it should be http://localhost/virtualdir/Some-Page-Slug. Of course, this generates 404 error. How can I solve this to be universally useful and working under all circumstances? Should I store it differently in the database or should I transform it into correct form in my Views at runtime and how to do that?
