  • What is the correct way to create dynamic javascript in ASP.net MVC2?

    - by sabbour
    I'm creating a Google Maps partial view/user control in my project that is passed a strongly typed list of objects containing latitude and longitude values. Currently, this is the code I have for the partial: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IEnumerable<Project.Models.Entities.Location>>" %> <!-- Place for google to put the map --> <div id="report_map_canvas" style="width: 100%; height: 728px; margin-bottom: 2px;"> </div> <script type='text/javascript'> google.load("maps", "2"); $(document).ready(initializeMap); function initializeMap() { if (GBrowserIsCompatible()) { var map = new GMap2(document.getElementById('report_map_canvas')); map.setCenter(new GLatLng(51.5, -0.1167), 2); <% foreach (var item in Model) { %> map.addOverlay(new GMarker(new GLatLng('<%= Html.Encode(item.latitude)%>','<%= Html.Encode(item.longitude)%>'),{ title: '<%= Html.Encode(String.Format("{0:F}",item.speed)) %> km/h '})); <% } %> map.setUIToDefault(); } } </script> Is it right to dynamically create the javascript file this way by looping over the list and emitting javascript? Is there a better way to do it?

  • FlashBuilder 4 and Zend Framework error

    - by sig
    I am trying to use adobe flash builder 4 with a php service. I had it set up an older macbook running leopard, but just tried to set it up on my new laptop running snow leopard. I did all the same steps.. set the Flex Server to be PHP, set the web root and url. Then I go to Data-Connect To PHP and point it to a php file I have in my web root. It says it needs to install Zend, and claims it does so successfully, but then when I try to continue, I get an error. I don't understand.. this same setup works on my older laptop. (Yes, I checked the amf.production was false) Unable to retrieve operations and entities from the file Make sure that Zend Framework is installed correctly and the parameter "amf.production" is not set to true in the amf_config.ini file located in the project output folder. false), true);$default_config-merge(new Zend_Config_Ini($configfile, 'zendamf'));$default_config-setReadOnly();$amf = $default_config-amf;// Store configuration in the registryZend_Registry::set("amf-config", $amf);// Initialize AMF Server$server = new Zend_Amf_Server();$server-setProduction($amf-production);if(isset($amf-directories)) { $dirs = $amf-directories-toArray(); foreach($dirs as $dir) { // get the first character of the path. // If it does not start with slash then it implies that the path is relative to webroot.

  • Extracting [] elements from form collection - mvc - should use icollection but have mix of types

    - by bergin
    hi there. have looked at Phil Haacks project on books at http://haacked.com/archive/2008/10/23/model-binding-to-a-list.aspx which has been useful, but I have a mix of data types. I use a modelview so that i can have a mix of objects, in this case: Order (ie order.id, order.date etc), Customer, SoilSamplingOrder and a list of SoilSamplingSubJobs which is like this [0].id, [0].field, [1].id, [1].field etc Perhaps I should be using ICollection instead of List? I had problems getting UpdateModel to work so I used an extract from collection method. the first 4 method calls : orderRepository.FindOrder(id); etc give the model the original to be edited. but after this point i'm a little lost in how to update the subjobs. I hope i have delineated enough to make sense of the problem. [HttpPost] public ActionResult Edit(int id, FormCollection collection) { Order order = orderRepository.FindOrder(id); Customer cust = orderRepository.FindCustomer(order.customer_id); IList<SoilSamplingSubJob> sssj = orderRepository.FindSubOrders(id); SoilSamplingOrder sso = orderRepository.FindSoilSampleOrder(id); try { UpdateModel(order, collection.ToValueProvider()); UpdateModel(cust, collection.ToValueProvider()); UpdateModel(sso, collection.ToValueProvider()); IList<SoilSamplingSubJob> sssjs = orderRepository.extractSSSJ(collection); foreach (var sj in sssjs) UpdateModel(sso, collection.ToValueProvider()); orderRepository.Save(); return RedirectToAction("Details", new { id=order.order_id}); } catch { return View(); } }

  • Textured Primitives in XNA with a first person camera

    - by 131nary
    So I have a XNA application set up. The camera is in first person mode, and the user can move around using the keyboard and reposition the camera target with the mouse. I have been able to load 3D models fine, and they appear on screen no problem. Whenever I try to draw any primitive (textured or not), it does not show up anywhere on the screen, no matter how I position the camera. In Initialize(), I have: quad = new Quad(Vector3.Zero, Vector3.UnitZ, Vector3.Up, 2, 2); quadVertexDecl = new VertexDeclaration(this.GraphicsDevice, VertexPositionNormalTexture.VertexElements); In LoadContent(), I have: quadTexture = Content.Load<Texture2D>(@"Textures\brickWall"); quadEffect = new BasicEffect(this.GraphicsDevice, null); quadEffect.AmbientLightColor = new Vector3(0.8f, 0.8f, 0.8f); quadEffect.LightingEnabled = true; quadEffect.World = Matrix.Identity; quadEffect.View = Matrix.CreateLookAt(cameraPosition, cameraTarget, Vector3.Up); quadEffect.Projection = this.Projection; quadEffect.TextureEnabled = true; quadEffect.Texture = quadTexture; And in Draw() I have: this.GraphicsDevice.VertexDeclaration = quadVertexDecl; quadEffect.Begin(); foreach (EffectPass pass in quadEffect.CurrentTechnique.Passes) { pass.Begin(); GraphicsDevice.DrawUserIndexedPrimitives<VertexPositionNormalTexture>( PrimitiveType.TriangleList, quad.Vertices, 0, 4, quad.Indexes, 0, 2); pass.End(); } quadEffect.End(); I think I'm doing something wrong in the quadEffect properties, but I'm not quite sure what.

  • Entity Framework query

    - by carter-boater
    Hi all, I have a piece of code that I don't know how to improve it. I have two entities: EntityP and EntityC. EntityP is the parent of EntityC. It is 1 to many relationship. EntityP has a property depending on a property of all its attached EntityC. I need to load a list of EntityP with the property set correctly. So I wrote a piece of code to get the EntityP List first.It's called entityP_List. Then as I wrote below, I loop through the entityP_List and for each of them, I query the database with a "any" function which will eventually be translated to "NOT EXIST" sql query. The reason I use this is that I don't want to load all the attached entityC from database to memory, because I only need the aggregation value of their property. But the problem here is, the looping will query the databae many times, for each EntityP! So I am wondering if anybody can help me improve the code to query the database only once to get all the EntityP.IsAll_C_Complete set, without load EntityC to memory. foreach(EntityP p in entityP_List) { isAnyNotComoplete = entities.entityC.Any(c => c.IsComplete==false && c.parent.ID == p.ID); p.IsAll_C_Complete = !isAnyNotComoplete; } Thank you very much!

  • Custom .NET DSL

    - by Dmitriy Nagirnyak
    Hi, I am thinking about implementing a templating engine using only the plain C#/.NET 4 syntax with the benefit of static typing. Then on top of that templating language we could create Domain Specific Languages (let's say HTML4, XHTML, HTML5, RSS, Atom, Multipart Emails and so on). One of the best DSLs in .NET 4 (if not only one) is SharpDOM. It implements HTML-specific DSL. Looking at SharpDOM, I am really impressed of what you can do using .NET (4). So I believe there are some not-so-well-known ways for implementing custom DSLs in .NET 4. Possibly not as well as in Ruby, but still. So my the question would be: what are the C# (4) specific syntax features that can be used for implementing custom DSLs? Examples I can think of right now: // HTML - doesn't look tooo readable :) div(clas: "head", ul(clas: "menu", id: "main-menu", () => { foreach(var item in allItems) { li(item.Name) } }) // See how much noise it has with all the closing brackets? ) // Plain text (Email or something) - probably too simple Line("Dear {0}", user.Name); Line("You have been kicked off from this site"); For me it is really hard to come up with the syntax with least amount of noise. Please NOTE that I am not talking about another language (Boo, IronRuby etc), neither I am not talking about different templating engines (NHaml, Spark, StringTemplate etc). Thanks, Dmitriy.

  • How to refer to items in Dictionary<string, string> by integer index?

    - by Edward Tanguay
    I made a Dictionary<string, string> collection so that I can quickly reference the items by their string identifier. But I now also need to access this collective by index counter (foreach won't work in my real example). What do I have to do to the collection below so that I can access its items via integer index as well? using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace TestDict92929 { class Program { static void Main(string[] args) { Dictionary<string, string> events = new Dictionary<string, string>(); events.Add("first", "this is the first one"); events.Add("second", "this is the second one"); events.Add("third", "this is the third one"); string description = events["second"]; Console.WriteLine(description); string description = events[1]; //error Console.WriteLine(description); } } }

  • Kohana 3 ORM: How to get data from pivot table? and all other tables for that matter

    - by zenna
    I am trying to use ORM to access data stored, in three mysql tables 'users', 'items', and a pivot table for the many-many relationship: 'user_item' I followed the guidance from http://stackoverflow.com/questions/1946357/kohana-3-orm-read-additional-columns-in-pivot-tables and tried $user = ORM::factory('user',1); $user->items->find_all(); $user_item = ORM::factory('user_item', array('user_id' => $user, 'item_id' => $user->items)); if ($user_item->loaded()) { foreach ($user_item as $pivot) { print_r($pivot); } } But I get the SQL error: "Unknown column 'user_item.id' in 'order clause' [ SELECT user_item.* FROM user_item WHERE user_id = '1' AND item_id = '' ORDER BY user_item.id ASC LIMIT 1 ]" Which is clearly erroneous because Kohana is trying to order the elements by a column which doesn't exist: user_item.id. This id doesnt exist because the primary keys of this pivot table are the foreign keys of the two other tables, 'users' and 'items'. Trying to use: $user_item = ORM::factory('user_item', array('user_id' => $user, 'item_id' => $user->items)) ->order_by('item_id', 'ASC'); Makes no difference, as it seems the order_by() or any sql queries are ignored if the second argument of the factory is given. Another obvious error with that query is that the item_id = '', when it should contain all the elements. So my question is how can I get access to the data stored in the pivot table, and actually how can I get access to the all items held by a particular user as I even had problems with that? Thanks

  • Adding StyleSheets Programmatically in Asp.Net

    - by Braveyard
    I want to add StyleSheets programmatically in the head section but one of the examples I saw seemed to need to many lines of code to add just one style sheet even though I may need a lot: Example Code: HtmlLink css = new HtmlLink(); css.Href = "css/fancyforms.css"; css.Attributes["rel"] = "stylesheet"; css.Attributes["type"] = "text/css"; css.Attributes["media"] = "all"; Page.Header.Controls.Add(css); I also use Page.Header.RenderControl() method but it didn't work either. Object null something error was thrown. I also used Page.Header.InnerHtml and InnerText += "<link .... "/> things but they threw the Literal error which is I think common error. I used this code : List<Literal> cssFiles = new List<Literal>(); cssFiles.Add(new Literal() { Text = @"<link href=""" + ResolveUrl("~/Resources/Styles/MainMaster/MainDesign.css") + @""" type=""text/css"" rel=""stylesheet"" />" }); cssFiles.Add(new Literal() { Text = @"<link href=""" + ResolveUrl("~/Resources/Styles/MainMaster/MainLayout.css") + @""" type=""text/css"" rel=""stylesheet"" />" }); AddStyleRange(cssFiles); private void AddStyleRange(List<Literal> cssFiles) { foreach (Literal item in cssFiles) { this.Header.Controls.Add(item); } } It worked at first but when I change the pages it stopped working. I am using Master Page and I am writing these codes on Master.cs file and also some people recommended to use this.Header instead of Page.Header but when I built it throws an error which says I cannot declare that like this. It shouldn't be that hard to add many styles. It is getting complicated.

  • C# Reflection StackTrace get value

    - by John
    I'm making pretty heavy use of reflection in my current project to greatly simplify communication between my controllers and the wcf services. What I want to do now is to obtain a value from the Session within an object that has no direct access to HttpSessionStateBase (IE: Not a controller). For example, a ViewModel. I could pass it in or pass a reference to it etc. but that is not optimal in my situation. Since everything comes from a Controller at some point in my scenario I can do the following to walk the sack to the controller where the call originated, pretty simple stuff: var trace = new System.Diagnostics.StackTrace(); foreach (var frame in trace.GetFrames()) { var type = frame.GetMethod().DeclaringType; var prop = type.GetProperty("Session"); if(prop != null) { // not sure about this part... var value = prop.GetValue(type, null); break; } } The trouble here is that I can't seem to work out how to get the "instance" of the controller or the Session property so that I can read from it.

  • Programmatically Add Controls to WPF Form

    - by user210757
    I am trying to add controls to a UserControl dynamically (programatically). I get a generic List of objects from my Business Layer (retrieved from the database), and for each object, I want to add a Label, and a TextBox to the WPF UserControl and set the Position and widths to make look nice, and hopefully take advantage of the WPF Validation capabilities. This is something that would be easy in Windows Forms programming but I'm new to WPF. How do I do this (see comments for questions) Say this is my object: public class Field { public string Name { get; set; } public int Length { get; set; } public bool Required { get; set; } } Then in my WPF UserControl, I'm trying to create a Label and TextBox for each object: public void createControls() { List<Field> fields = businessObj.getFields(); Label label = null; TextBox textbox = null; foreach (Field field in fields) { label = new TextBox(); // HOW TO set text, x and y (margin), width, validation based upon object? // i have tried this without luck: // Binding b = new Binding("Name"); // BindingOperations.SetBinding(label, Label.ContentProperty, b); MyGrid.Children.Add(label); textbox = new TextBox(); // ??? MyGrid.Children.Add(textbox); } // databind? this.DataContext = fields; }

  • How to search inbox using zend mail

    - by Bob Cavezza
    The following is a function from zend_mail_protocol_imap. i read that to search emails, I would want to override it using zend_mail_storage_imap (which is what I'm using now to grab email from gmail). I copy and pasted the following function into zend_mail_storage_imap, but I'm having issues with the params. I can't find documentation on what to use for the array $params. I initially thought it was the search term before reading it more thoroughly. I'm out of ideas. Here's the function... /** * do a search request * * This method is currently marked as internal as the API might change and is not * safe if you don't take precautions. * * @internal * @return array message ids */ public function search(array $params) { $response = $this->requestAndResponse('SEARCH', $params); if (!$response) { return $response; } foreach ($response as $ids) { if ($ids[0] == 'SEARCH') { array_shift($ids); return $ids; } } return array(); } Initially I thought this would do the trick... $storage = new Zend_Mail_Storage_Imap($imap); $searchresults = $storage->search('search term'); But nope, I need to send the info in an array. Any ideas?

  • Save all xml nodes to db without looping through it

    - by AndreMiranda
    I have this xml: <Path> <Record> <ID>6534808</ID> <Distance>1.05553036073736</Distance> </Record> <Record> <ID>6542471</ID> <Distance>1.05553036073736</Distance> </Record> ... and about more 500 nodes </Path> And I'm using the code below to get all "Record" nodes: XmlNodeList paths = xDoc.SelectNodes("//Record"); And, after that, I save each record to database. But, the problem is that I'm using a foreach to loop through this nodes and the count of this nodes may be more than 500, sometimes it gets up to 1000 "Records" node. And this gets too long... Is there a way to save all of these nodes without looping through it? Thanks!!

  • DropDownListFor and relating my lambda to my ViewModel

    - by Daniel Harvey
    After googling for a while I'm still drawing a blank here. I'm trying to use a ViewModel to pull and provide a dictionary to a drop down list inside a strongly typed View: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="Notebook.ViewModels.CorporationJoinViewModel" %> ... <%: Html.DropDownListFor(c => c.CorpDictionary.Keys, new SelectList(Model.CorpDictionary, "Value", "Key"))%> I'm getting the error CS1061: 'object' does not contain a definition for 'CorpDictionary' and no extension method 'CorpDictionary' accepting a first argument of type 'object' could be found and the relevant bit of my ViewModel public class CorporationJoinViewModel { DB _db = new DB(); // data context public Dictionary<int, string> CorpDictionary { get { Dictionary<int, string> corporations = new Dictionary<int, string>(); int x = 0; foreach (Corporation corp in _db.Corporations) { corporations.Add(x, corp.name); } return corporations; } } I'll admit i have a pretty magical understanding of how linq is finding my ViewModel object from that lambda, and the error message is making me think it's not. Is my problem the method I'm using to pass the data? What am I missing here?

  • ASP.NET MVC Strongly Typed Widgets

    - by Ben
    I have developed a plugin system that makes it easy to plug in new logic to an application. Now I need to provide the ability to easily add UI widgets. There are already some good responses on how to create a portal system (like iGoogle) with ASP.NET MVC, and I'm fine about the overall concept. My question is really about how we make strongly typed widgets. Essentially when we set up a widget we define the controller and action names that are used to render that widget. We can use one controller action for widgets that are not strongly typed (since we just return PartialView(widgetControlName) without a model) For widgets that are strongly typed (for example to an IList) we would need to add a new controller action (since I believe it is not possible to use Generics with ActionResult e.g. ActionResult). The important thing is that the widget developers should not change the main application controllers. So my two thoughts are this: Create new controllers in a separate class library Create one partial WidgetController in the main web project and then extend this in other projects (is this even possible?) - not possible as per @mfeingold As far as the development of the widgets (user controls) go, we can just use post build events from our extension projects to copy these into the Views/Widgets directory. Is this a good approach. I am interested to here how others have handled this scenario. Thanks Ben P.S - in case it helps, an example of how we can render widgets - without using Javascript <%foreach (var widget in Model) {%> <%if (widget.IsStronglyTyped) { Html.RenderAction(widget.Action, widget.Controller); } else { Html.RenderPartial(widget.ControlName); } %> <%} %>

  • DDD and MVC: Difference between 'Model' and 'Entity'

    - by Nathan Loding
    I'm seriously confused about the concept of the 'Model' in MVC. Most frameworks that exist today put the Model between the Controller and the database, and the Model almost acts like a database abstraction layer. The concept of 'Fat Model Skinny Controller' is lost as the Controller starts doing more and more logic. In DDD, there is also the concept of a Domain Entity, which has a unique identity to it. As I understand it, a user is a good example of an Entity (unique userid, for instance). The Entity has a life-cycle -- it's values can change throughout the course of the action -- and then it's saved or discarded. The Entity I describe above is what I thought Model was supposed to be in MVC? How off-base am I? To clutter things more, you throw in other patterns, such as the Repository pattern (maybe putting a Service in there). It's pretty clear how the Repository would interact with an Entity -- how does it with a Model? Controllers can have multiple Models, which makes it seem like a Model is less a "database table" than it is a unique Entity. So, in very rough terms, which is better? No "Model" really ... class MyController { public function index() { $repo = new PostRepository(); $posts = $repo->findAllByDateRange('within 30 days'); foreach($posts as $post) { echo $post->Author; } } } Or this, which has a Model as the DAO? class MyController { public function index() { $model = new PostModel(); // maybe this returns a PostRepository? $posts = $model->findAllByDateRange('within 30 days'); while($posts->getNext()) { echo $posts->Post->Author; } } } Both those examples didn't even do what I was describing above. I'm clearly lost. Any input?

  • Can someone help me refactor this C# linq business logic for efficiency?

    I feel like this is not a very efficient way of using linq. I was hoping somebody on here would have a suggestion for a refactor. I realize this code is not very pretty, as I was in a complete rush. public class Workflow { public void AssignForms() { using (var cntx = new ProjectBusiness.Providers.ProjectDataContext()) { var emplist = (from e in cntx.vw_EmployeeTaskLists where e.OwnerEmployeeID == null select e).ToList(); foreach (var emp in emplist) { // if employee has a form assigned: break; if (emp.GRADE > 15 || (emp.Pay_Plan.ToLower().Contains("al") || emp.Pay_Plan.ToLower().Contains("ex"))) { //Assign278(); } else if ((emp.Series.Contains("0905") || emp.Series.Contains("0511") || emp.Series.Contains("0110") || emp.Series.Contains("1801")) || (emp.GRADE >= 12 && emp.GRADE <= 15)) { var emptask = new ProjectBusiness.Providers.EmployeeTask(); emptask.TimespanID = cntx.Timespans.SingleOrDefault(t => t.BeginDate.Year == DateTime.Today.Year & t.EndDate.Year == DateTime.Today.Year).TimespanID; var FormID = (from f in cntx.Forms where f.FormName.Contains("450") select f.FormID).FirstOrDefault(); var TaskStatusID = (from s in cntx.TaskStatus where s.StatusDescription.ToLower() == "not started" select s.TaskStatusID).FirstOrDefault(); Assign450((int)emp.EmployeeID, FormID, TaskStatusID, emptask); cntx.EmployeeTasks.InsertOnSubmit(emptask); } else { //Assign185(); } } cntx.SubmitChanges(); } } private void Assign450(int EmployeeID, int FormID, int TaskStatusID, ProjectBusiness.Providers.EmployeeTask emptask) { emptask.FormID = FormID; emptask.OwnerEmployeeID = EmployeeID; emptask.AssignedToEmployeeID = EmployeeID; emptask.TaskStatusID = TaskStatusID; emptask.DueDate = DateTime.Today; } }

  • Synchronizing a collection of wrapped objects with a collection of unwrapped objects

    - by Kenneth Cochran
    I have two classes: Employee and EmployeeGridViewAdapter. Employee is composed of several complex types. EmployeeGridViewAdapter wraps a single Employee and exposes its members as a flattened set of system types so a DataGridView can handle displaying, editing, etc. I'm using VS's builtin support for turning a POCO into a data source, which I then attach to a BindingSource object. When I attach the DataGridView to the BindingSource it creates the expected columns and at runtime I can perform the expected CRUD operations. All is good so far. The problem is the collection of adapters and the collection of employees aren't being synchronized. So all the employees I create an runtime never get persisted. Here's a snippet of the code that generates the collection of EmployeeGridViewAdapter's: var employeeCollection = new List<EmployeeGridViewAdapter>(); foreach (var employee in this.employees) { employeeCollection.Add(new EmployeeGridViewAdapter(employee)); } this.view.Employees = employeeCollection; Pretty straight forward but I can't figure out how to synchronize changes back to the original collection. I imagine edits are already handled because both collections reference the same objects but creating new employees and deleting employees aren't happening so I can't be sure.

  • Update one-to-many EntityKey using Foreign Key

    - by User.Anonymous
    To use by the easiest way Entity Framework, I use partial class to add Foreign Key on most important Entities Model. For example, I have an Entity "CONTACT" which have "TITLE", "FUNCTION" and others. When I update a CONTACT, with this code, Foreign Key are automatically updated : public int? TitId { get { if (this.TITLE_TIT != null) return TITLE_TIT.TIT_ID; return new Nullable<int>(); } set { this.TITLE_TITReference.EntityKey = new System.Data.EntityKey("Entities.TITLE_TIT", "TIT_ID", value); } } But I have a join with ACTIVITY, that can have many CONTACT, and I don't know how to update EntityKey on setters. public IEnumerable<EntityKeyMember> ActId { get { List<EntityKeyMember> lst = new List<EntityKeyMember>(); if (this.ACT_CON2 != null) { foreach (ACT_CON2 id in this.ACT_CON2.ToList()) { EntityKeyMember key = new EntityKeyMember(id.CON_ID.ToString(),id.ACT_ID); lst.Add(key); } } return lst; } set { this.ACT_CON2.EntityKey = new System.Data.EntityKey("Entities.ACT_CON2", value); } } How set many EntityKey ? Thank you.

  • Getting DirectoryNotFoundException when trying to Connect to Device with CoreCon API

    - by ageektrapped
    I'm trying to use the CoreCon API in Visual Studio 2008 to programmatically launch device emulators. When I call device.Connect(), I inexplicably get a DirectoryNotFoundException. I get it if I try it in PowerShell or in C# Console Application. Here's the code I'm using: static void Main(string[] args) { DatastoreManager dm = new DatastoreManager(1033); Collection<Platform> platforms = dm.GetPlatforms(); foreach (var p in platforms) { Console.WriteLine("{0} {1}", p.Name, p.Id); } Platform platform = platforms[3]; Console.WriteLine("Selected {0}", platform.Name); Device device = platform.GetDevices()[0]; device.Connect(); Console.WriteLine("Device Connected"); SystemInfo info = device.GetSystemInfo(); Console.WriteLine("System OS Version:{0}.{1}.{2}", info.OSMajor, info.OSMinor, info.OSBuildNo); Console.ReadLine(); } My question: Does anyone know why I'm getting this error? I'm running this on WinXP 32-bit, plain jane Visual Studio 2008 Pro. I imagine it's some config issue since I can't do it from a Console app or PowerShell. Here's the stack trace as requested: System.IO.DirectoryNotFoundException was unhandled Message="The system cannot find the path specified.\r\n" Source="Device Connection Manager" StackTrace: at Microsoft.VisualStudio.DeviceConnectivity.Interop.ConManServerClass.ConnectDevice() at Microsoft.SmartDevice.Connectivity.Device.Connect() at ConsoleApplication1.Program.Main(String[] args) in C:\Documents and Settings\Thomas\Local Settings\Application Data\Temporary Projects\ConsoleApplication1\Program.cs:line 23 at System.AppDomain._nExecuteAssembly(Assembly assembly, String[] args) at System.AppDomain.ExecuteAssembly(String assemblyFile, Evidence assemblySecurity, String[] args) at Microsoft.VisualStudio.HostingProcess.HostProc.RunUsersAssembly() at System.Threading.ThreadHelper.ThreadStart_Context(Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ThreadHelper.ThreadStart() InnerException:

  • C# Thread-safe Extension Method

    - by Wonko the Sane
    Hello All, I may be waaaay off, or else really close. Either way, I'm currently SOL. :) I want to be able to use an extension method to set properties on a class, but that class may (or may not) be updated on a non-UI thread, and derives from a class the enforces updates to be on the UI thread (which implements INotifyPropertyChanged, etc). I have a class defined something like this: public class ClassToUpdate : UIObservableItem { private readonly Dispatcher mDispatcher = Dispatcher.CurrentDispatcher; private Boolean mPropertyToUpdate = false; public ClassToUpdate() : base() { } public Dispatcher Dispatcher { get { return mDispatcher; } } public Boolean PropertyToUpdate { get { return mPropertyToUpdate; } set { SetValue("PropertyToUpdate", ref mPropertyToUpdate, value; } } } I have an extension method class defined something like this: static class ExtensionMethods { public static IEnumerable<T> SetMyProperty<T>(this IEnumerable<T> sourceList, Boolean newValue) { ClassToUpdate firstClass = sourceList.FirstOrDefault() as ClassToUpdate; if (firstClass.Dispatcher.Thread.ManagedThreadId != System.Threading.Thread.CurrentThread.ManagedThreadId) { // WHAT GOES HERE? } else { foreach (var classToUpdate in sourceList) { (classToUpdate as ClassToUpdate ).PropertyToUpdate = newValue; yield return classToUpdate; } } } } Obviously, I'm looking for the "WHAT GOES HERE" in the extension method. Thanks, wTs

  • How can I make a WPF combo box have the width of its widest element in XAML ?

    - by csuporj
    I know how to do it in code, but can this be done in XAML ? Window1.xaml: <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <Grid> <ComboBox Name="ComboBox1" HorizontalAlignment="Left" VerticalAlignment="Top"> <ComboBoxItem>ComboBoxItem1</ComboBoxItem> <ComboBoxItem>ComboBoxItem2</ComboBoxItem> </ComboBox> </Grid> </Window> Window1.xaml.cs: using System.Windows; using System.Windows.Controls; namespace WpfApplication1 { public partial class Window1 : Window { public Window1() { InitializeComponent(); double width = 0; foreach (ComboBoxItem item in ComboBox1.Items) { item.Measure(new Size( double.PositiveInfinity, double.PositiveInfinity)); if (item.DesiredSize.Width > width) width = item.DesiredSize.Width; } ComboBox1.Measure(new Size( double.PositiveInfinity, double.PositiveInfinity)); ComboBox1.Width = ComboBox1.DesiredSize.Width + width; } } }
