  • MVC Client Validation from Service Layer

    - by GibboK
    I'm following this article http://www.asp.net/mvc/tutorials/older-versions/models-(data)/validating-with-a-service-layer-cs to include a Service Layer with Business Logic in my MVC Web Application. I'm able to pass messages from the Service Layer to the View Model in a Html.ValidationSummary using ModelState Class. I perform basic validation logic on the View Model (using DataAnnotation attributes) and I have ClientValidation enabled by default which displaying the error message on every single field of my form. The Business logic error message which come from the Service Layer are being displayed on Html.ValidationSummary only after Posting the form to the Server. After Validation from the Service Layer I would like highlight one or more fields and have the message from the Service Layer showing on these fields instead that the Html.ValidationSummary. Any idea how to do it? Thanks

  • Unable to set relative path for flash file in ASP.NET MVC using AC_FL_RunContent

    - by Mahesh
    Hi, I have a website using asp.net mvc in which I need to embed a flash file in view. I am unable to set the relative path for the flash file. Given below is the code I am using: AC_FL_RunContent( 'codebase', 'http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0', 'width', '487', 'height', '359', 'menu', 'false', 'movie', 'images/butterfly', 'quality', 'high', 'allowscriptaccess', 'sameDomain', 'pluginspage', 'http://www.macromedia.com/go/getflashplayer' ); where I copied butterfly.swf in a directory called images. images directory resides in the views folder. If I use code behind( default.aspx default.aspx.cs) in a different solution with the same folder strucuture, browser is able to load the flash file. Could you please throw some light on the MVC folder structure issue?? Thanks a lot. Mahesh

  • Can you expose XML webservices from a Windows Forms Application?

    - by Andrei
    This might sound like a silly question, but when I search for webservices, I get no information about how to create them in a windows forms application. The only result is how to create and expose them by creating an .aspx page. So my questions is: Can you create and expose webservices within a windows forms application or are they somehow tied in with .asp pages? Thanks! later edit: Is there an example of how to create a webservice in a .cs file and not in a .aspx file?

  • adhoc struct/class in C#?

    - by acidzombie24
    Currently i am using reflection with sql. I find if i want to make a specialize query it is easiest to get the results by creating a new class inheriting from another and adding the 2 members/columns for my specialized query. Then due to reflections in the lib in my c# code i can write foreach(var v in list) { v.AnyMember and v.MyExtraMember) Now instead of having the class scattered around or modifying my main DB.cs file can i define a class inside a function? I know i can create an anonymous object by writing new {name=val, name2=...}; but i need a to pass this class in a generic function func(query, args);

  • Best disassembler tool for the .NET reflector?

    - by Joan Venge
    What's the best disassembler tool for the .NET reflector? By best I mean, saving a .NET assembly in a disassembled state in most readable, most likely to compile with fewer changes. The current one I use doesn't show simplified enumeration but shows the full IEnumerable implementations with MoveNext, etc with member names like: this.<4_state CS$<9_CachedAnonymousMethodDelegate3 Btw I am not trying to steal code, just trying out certain things on an already existing assembly instead of writing a similar thing from scratch. In the end, it's what I will learn from this that will stay, not the modified assembly.

  • Can I use multiple step definition files with SpecFlow?

    - by Roger Lipscombe
    I'm using SpecFlow to do some BDD-style testing. Some of my features are UI tests, so they use WatiN. Some aren't UI tests, so they don't. At the moment, I have a single StepDefinitions.cs file, covering all of my features. I have a BeforeScenario step that initializes WatiN. This means that all of my tests start up Internet Explorer, whether they need it or not. Is there any way in SpecFlow to have a particular feature file associated with a particular set of step definitions? Or am I approaching this from the wrong angle?

  • WPF/MVVM - should we create a different Class for each ViewModel ?

    - by FMFF
    I'm attempting the example from the excellent "How Do I" video for MVVM by Todd Miranda found in MSDN. I'm trying to adapt the example for my learning purpose. In the example, he has a ViewModel called EmployeeListViewModel. Now if I want to include Departments, should I create another ViewModel such as DepartmentListViewModel? The example has EmployeeRepository as the Data Source. In my case, I'm trying to use an Entity object as the datasource (Employees.edmx in Model folder and EmployeeRepository.cs in DataAccess folder). If I want to display the list of Departments, should I create a separate class called DepartmentRepository and put all department related method definitions there? What if I want to retrieve the employee name and their department's name together? Where should I place the methods for this? I'm very new to WPF and MVVM and please let me know if any of the above needs to be re-phrased. Thank you for all the help.

Charing a hourly rate or a price for the whole project? How you did it and why? Thanks

  • Change LINQ2SQL property in partial class?

    - by Fermin
    Hi, I have a table in my LINQ2SQL diagram with a column called DayOfWeek in table JourneyBooking. The designer.cs has the definition of this as: [Column(Storage="_DayOfWeek", DbType="TinyInt NOT NULL")] public int DayOfWeek { get { return this._DayOfWeek; } set { if ((this._DayOfWeek != value)) { this.OnDayOfWeekChanging(value); this.SendPropertyChanging(); this._DayOfWeek = value; this.SendPropertyChanged("DayOfWeek"); this.OnDayOfWeekChanged(); } } } I have a partial class for the JourneyBooking class. Is it possible to extend/overwrite the above DayOfWeek property with my own property? The issue I am having is that DayOfWeek is 0-6 in C# but 1-7 in SQL, so I was thinking that I could overwrite the DayOfWeek property to subtract or add 1 depending on whether it was a get or set, is this possible or would I need to re-write all of the above code in my partial class?

  • wpf - Which one is better? Style or User Control?

    - by Archie
    Hello, I wanted to know which one amongst Style and UserControl would be better to use in WPF? For example: I have created an image button in two different ways. One uses Style and ContentTemplate property is set. It uses one other class with dependency properties. The other way is i have created a UserControl which has a button and its content property is set. UserControl.xaml.cs file also contains the dependency properties. For Code details see the answers of this question: http://stackoverflow.com/questions/2734825/custom-button-template-in-wpf Which one would be better to use? Can anyone tell me in which scenario one should go for Style or UserControl or any CustomControl? Thanks in advance.

  • WCF Windows service permissions problem

    - by Elad
    I have created a WCF service and hosted it using Windows Services host. To install the project I created an installation project (as described here). In the tutorial, it says to define in the ProjectInstaller.cs the serviceProcessInstaller1 Account property to be Network Service. When using this setting the service did not started on the server. When I tried to start the process manually, it immediately return to stopped state. After when I changed the Account to LocalSystem the service works properly. My questions are: Any ideas why it won't work with Network Service account? What are the security implications of using a server with LocalSystem account? This server is used locally in the intranet as a reporting server for other servers.

  • Please list here your deliberate practices in software development...

    - by JDelage
    What are your deliberate practices in relation with your work as a software developer / professional, or as a CS student? Deliberate practice are exercise and repetitions targeted specifically at an individual's weak points and meant to consistently stretch / grow someone's ability. It was described in this Anders Ericsson paper. To qualify as a deliberate practice, the exercise must satisfy the following: Is not inherently enjoyable. Is not play or paid practice. Is relevant to the skill being developed. Is not simply watching the skill being performed. Requires effort and attention from the learner. Often involves activities selected by a coach or teacher to facilitate learning. Please answer with one practice per answer. I'll seed the question with one possible answer.

    - by Nickson
    Am adding an Entity Data Model to an ASP.NET website. When i Add New Item to the website and select ADO.NET Entity Data Model, am asked for the model name and language. I go a head and select Visual Basic as the language, the model is added and the site can compile with out any issues. however, the model it adds a ModelName.Designer.cs source file, instead of a ModelName.Designer.vb source file. am thinking this is strange as its happening with only one of my website. my other sites have .vb designer source file for their Entity Data Models. The site still compiles with out any errors but am afraid some thing is not right. any one experienced this?, is this normal behavior?

  • C# CF: How to open specific file extension with my program

    - by nuttynibbles
    Hi, Im developing a mobile application in dot net Compact framework. I managed to edit the registry HKEY_CLASSES_ROOT so that a click on file with .xyz extension will open my application. basically, i need to do some operation on this file when it's clicked. however, i realise that if i do that the first time, it reaches program.cs at static void Main. but when the program is running and i click on the file with .xyz extension again, it doesnt loads the program static void Main. i tried setting breakpoints at the form that is currently running but still nothing. so where does it go to? how can i detect file .xyz is clicked and do something??

  • Popup window keeps opening after I close it and refresh the page?

    - by Xaisoft

I have to leave the page and come back for it to stop popping up on every refresh. Is this behavior by default or is there a fix to it? hypPopup.Attributes.Add is done in the Page_Load

  • Custom tool error: Command.proto:11:18: "Message2" is not defined.

    - by cornerback84
    I am using the latest version of protobuf-net with VS2008 integration. I have created 2 messages (Message1 and Message2), 1 message in 1 proto file. When I try to reference Message2 in Message1 the code generator tool gives me error "Message2" is not defined and won't generate the code file. The package for both messages is same. It look like that because of the integration of the tool with VS2008 it expects all the messages in same .proto file to compile. Currently I have to paste an empty message with same name in Message1.proto file, like this: message Message1 { optional Message2 message2 = 1; } message Message2 { } And then later on remove the declaration of class Message2 from Message1.cs. Are there any settings that I need to do so to avoid this error, or is providing an empty declaration the only way?

  • How to display the properties of a Scheduled Task?

    - by TooFat
    I have C# app that uses a Form to set a bunch of settings. Those settings can be read by a Console App so it can run via the built in Windows Task Scheduler. I would like to be able to simply open up a scheduled task as if I had just opened it from the gui in Windows so the user can set all the settings for the scheduled task. I know I can use a library like http://www.codeproject.com/KB/cs/tsnewlib.aspx but I would rather not have to recreate all the options in a WinForm when everything is already available in Windows. Does anyone know how I can programattically display the built in Windows Task Scheduler from C#?

  • string extension method - Not available through WebMethod

    - by Peter Bridger
    I've written a simple extension method for a web project, it sits in a class file called StringExtensions.cs which contains the following code: using System; using System.Collections.Generic; using System.Linq; using System.Web; /// <summary> /// Useful extensions for string /// </summary> static class StringExtensions { /// <summary> /// Is string empty /// </summary> /// <param name="value"></param> /// <returns></returns> public static bool IsEmpty(this string value) { return value.Trim().Length == 0; } } I can access this extension method from all the classes I have within the App_Code directory. However I have a web page called JSON.aspx that contains a series of [WebMethods] - within these I cannot see the extension method - I must be missing something very obvious!

  • Does the order of readonly variable declarations guarantee the order in which the values are set?

    - by Jason Down
    Say I were to have a few readonly variables for filepaths, would I be able to guarantee the order in which the values are assigned based on the order of declaration? e.g. readonly string basepath = @"my\base\directory\location"; readonly string subpath1 = basepath + @"\abc\def"; readonly string subpath2 = basepath + @"\ghi\klm"; Is this a safe approach or is it possible that basepath may still be the default value for a string at the time subpath1 and subpath2 make a reference to the string? I realize I could probably guarantee the order by assigning the values in a constructor instead of at the time of declaration. However, I believe this approach wouldn't be possible if I needed to declare the variables inside of a static class (e.g. Program.cs for a console application, which has a static void Main() procedure instead of a constructor).

  • Managing EntityConnection lifetime

    - by kervin
    There have been many question on managing EntityContext lifetime, e.g. http://stackoverflow.com/questions/813457/instantiating-a-context-in-linq-to-entities I've come to the conclusion that the entity context should be considered a unit-of-work and therefore not reused. Great. But while doing some research for speeding up my database access, I ran into this blog post... Improving Entity Framework Performance The post argues that EFs poor performance compared to other frameworks is often due to the EntityConnection object being created each time a new EntityContext object is needed. To test this I manually created a static EntityConnection in Global.asax.cs Application_Start(). I then converted all my context using statements to using( MyObjContext currContext = new MyObjeContext(globalStaticEFConnection) { .... } This seems to have sped things up a bit without any errors so far as far as I can tell. But is this safe? Does using a applicationwide static EntityConnection introduce race conditions? Best regards, Kervin
