  • ASP.NET MVC Map String Url To A Route Value Object

    - by mwgriffiths
    I am creating a modular ASP.NET MVC application using areas. In short, I have created a greedy route that captures all routes beginning with {application}/{*catchAll}. Here is the action: // get /application/index public ActionResult Index(string application, object catchAll) { // forward to partial request to return partial view ViewData["partialRequest"] = new PartialRequest(catchAll); // this gets called in the view page and uses a partial request class to return a partial view } Example: The Url "/Application/Accounts/LogOn" will then cause the Index action to pass "/Accounts/LogOn" into the PartialRequest, but as a string value. // partial request constructor public PartialRequest(object routeValues) { RouteValueDictionary = new RouteValueDictionary(routeValues); } In this case, the route value dictionary will not return any values for the routeData, whereas if I specify a route in the Index Action: ViewData["partialRequest"] = new PartialRequest(new { controller = "accounts", action = "logon" }); It works, and the routeData values contains a "controller" key and an "action" key; whereas before, the keys are empty, and therefore the rest of the class wont work. So my question is, how can I convert the "/Accounts/LogOn" in the catchAll to "new { controller = "accounts", action = "logon" }"?? If this is not clear, I will explain more! :) Matt This is the "closest" I have got, but it obviously wont work for complex routes: // split values into array var routeParts = catchAll.ToString().Split(new char[] { '/' }, StringSplitOptions.RemoveEmptyEntries); // feels like a hack catchAll = new { controller = routeParts[0], action = routeParts[1] };

  • findViewById returns null in new Intent

    - by drozzy
    I am having a problem where in the started Intent, the findViewById returns null. Is there anything special I should know about starting a new intent? It goes something like this for me: //in the MainList class Intent stuffList = new Intent(this, StuffList.class); then in the new Stuff's constructor: public class StuffList extends ListActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); this.setContentView(R.layout.stuff_list); ... this.setListAdapter(new StuffAdapter(this, my_cursor)); and in the StuffAdapter I do my usual view and data retrieval. Note the line where findViewById returns null: class ViewWrapper{ View base; TextView label = null; ViewWrapper(View base){ this.base = base; } TextView getLabel(){ if(label == null){ label = (TextView)base.findViewById(R.id.my_label); // returns NULL } return label;} } class StuffAdapter extends CursorAdapter{ StuffAdapter(Context context, Cursor cursor){ super(context, cursor); } @Override public View newView(Context context, Cursor cursor, ViewGroup parent) { LayoutInflater inflater = getLayoutInflater(); View row = inflater.inflate(R.layout.stuff_list, parent, false); ViewWrapper wrapper = new ViewWrapper(row); row.setTag(wrapper); return(row); } @Override public void bindView(View row, Context context, Cursor cursor) { ViewWrapper wrapper = (ViewWrapper)row.getTag(); TextView label = wrapper.getLabel(); // also NULL //this throws exception of course label.setText(cursor.getString("title")); } } The curious thing is that in the class that calls intent (MainList class), I do Exactly the same thing (i list a bunch of objects), and it Works! however when I try to do it in an Intent - it can't seem to find the view by id.

  • Managing Instances in Python

    - by BeensTheGreat
    Hello, I am new to Python and this is my first time asking a stackOverflow question, but a long time reader. I am working on a simple card based game but am having trouble managing instances of my Hand class. If you look below you can see that the hand class is a simple container for cards(which are just int values) and each Player class contains a hand class. However, whenever I create multiple instances of my Player class they all seem to manipulate a single instance of the Hand class. From my experience in C and Java it seems that I am somehow making my Hand class static. If anyone could help with this problem I would appreciate it greatly. Thank you, Thad To clarify: An example of this situation would be p = player.Player() p1 = player.Player() p.recieveCard(15) p1.recieveCard(21) p.viewHand() which would result in: [15,21] even though only one card was added to p Hand class: class Hand: index = 0 cards = [] #Collections of cards #Constructor def __init__(self): self.index self.cards def addCard(self, card): """Adds a card to current hand""" self.cards.append(card) return card def discardCard(self, card): """Discards a card from current hand""" self.cards.remove(card) return card def viewCards(self): """Returns a collection of cards""" return self.cards def fold(self): """Folds the current hand""" temp = self.cards self.cards = [] return temp Player Class import hand class Player: name = "" position = 0 chips = 0 dealer = 0 pHand = [] def __init__ (self, nm, pos, buyIn, deal): self.name = nm self.position = pos self.chips = buyIn self.dealer = deal self.pHand = hand.Hand() return def recieveCard(self, card): """Recieve card from the dealer""" self.pHand.addCard(card) return card def discardCard(self, card): """Throw away a card""" self.pHand.discardCard(card) return card def viewHand(self): """View the players hand""" return self.pHand.viewCards() def getChips(self): """Get the number of chips the player currently holds""" return self.chips def setChips(self, chip): """Sets the number of chips the player holds""" self.chips = chip return def makeDealer(self): """Makes this player the dealer""" self.dealer = 1 return def notDealer(self): """Makes this player not the dealer""" self.dealer = 0 return def isDealer(self): """Returns flag wether this player is the dealer""" return self.dealer def getPosition(self): """Returns position of the player""" return self.position def getName(self): """Returns name of the player""" return self.name

  • Access cost of dynamically created objects with dynamically allocated members

    - by user343547
    I'm building an application which will have dynamic allocated objects of type A each with a dynamically allocated member (v) similar to the below class class A { int a; int b; int* v; }; where: The memory for v will be allocated in the constructor. v will be allocated once when an object of type A is created and will never need to be resized. The size of v will vary across all instances of A. The application will potentially have a huge number of such objects and mostly need to stream a large number of these objects through the CPU but only need to perform very simple computations on the members variables. Could having v dynamically allocated could mean that an instance of A and its member v are not located together in memory? What tools and techniques can be used to test if this fragmentation is a performance bottleneck? If such fragmentation is a performance issue, are there any techniques that could allow A and v to allocated in a continuous region of memory? Or are there any techniques to aid memory access such as pre-fetching scheme? for example get an object of type A operate on the other member variables whilst pre-fetching v. If the size of v or an acceptable maximum size could be known at compile time would replacing v with a fixed sized array like int v[max_length] lead to better performance? The target platforms are standard desktop machines with x86/AMD64 processors, Windows or Linux OSes and compiled using either GCC or MSVC compilers.

  • How does one create and use a pointer to an array of an unknown number of structures inside a class?

    - by user1658731
    Sorry for the confusing title... I've been playing around with C++, working on a project to parse a game's (Kerbal Space Program) save file so I can modify it and eventually send it over a network. I'm stuck with storing an unknown number of vessels and crew members, so I need to have an array of unknown size. Is this possible? I figured having a pointer to an array would be the way to go. I have: class SaveFileSystem { string version; string UT; int activeVessel; int numCrew; ??? Crews; // !! int numVessels; ??? Vessels; // !! } Where Crews and Vessels should be arrays of structures: struct Crew { string name; //Other stuff }; struct Vessel { string name; //Stuff }; I'm guessing I should have something like: this->Crews = new ???; this->Vessels = new ???; in my constructor to initialize the arrays, and attempt to access it with: this->Crews[0].name = "Ship Number One"; Does this make any sense??? I'd expect the "???"'s to involve a mess of asterisk's, like "*struct (*)Crews" but I have no real idea. I've got normal pointers down and such, but this is a tad over my head... I'd like to access the structures like in the last snippet, but if C++ doesn't like that I could do pointer arithmetic. I've looked into vectors, but I have an unhealthy obsession with efficiency, and it really pains me how you don't know what's going on behind it.

  • How do I find Microsoft APIs?

    - by Stephen
    I'm a java programmer, and if I see something that: I don't know about or just want to find a method description without opening an ide or am on support I type java [classname] into google, and there it is. If I try this crazy stunt for C# I'll come up with a whole heap of tutorials (how do I use it etc). If I manage to get to MSDN, I have to wade through a page describing every .net technology to see how their syntax references the same object, and then I have to find the appropriate page from there ([class name] Constructor) for example. This is even more pronounced, because I don't have Visual Studio, so I've got nothing to make it easier. There must be something I'm missing or don't know... how does this situation work for Microsoft developers? how can I make my life easier/searches better? are there techniques that work no matter what computer I'm on (e.g. require no computer setup/downloads) Notes It could be thought that java is just "java", but it's just that the java apis are only referenced/defined in the core language. For all the other languages on the JVM, it's assumed that you will just learn the correct syntax to use the java apis. I presume that .Net only lists a whole heap of languages as the api classes are actually different and have different interfaces capabilities (or some approximation of this presumption). Edit While searching msdn works... in the java space I can type 'java [anyclass]' and it will generally be found... whether it's a java core api or a third party library

  • Set Property Value on Master Page from Content Page

    - by Merk
    Hello, I tried following the advice posted here: http://stackoverflow.com/questions/1071920/set-property-value-on-master-page-from-content-page. Specifically the last post about creating a class. However, visual studio keeps giving me an error on my default.aspx.cs page when i try to set the value: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class _Default : BasePage { protected override int NavHighlight { get { return new{0} ; } } protected void Page_Load(object sender, EventArgs e) { } } It throws an error on new, the error being: cannot inplicity convert anonymoustype#1 to int Can someone tell me what i might have done wrong here?

  • .NET WebBrowser control with Adobe SVG Viewer

    I'm having problems with SVG files loading in a .NET 2.0 WebBrowser control. If I create a new WinForms application project, drag a WebBrowser control and a button onto the Form1.cs design surface, and add a line to the button's on-click handler to set the Url property of the WebBrowser control to an SVG file, I get two IE script errors at runtime (as in, the dialog you get when there is a Javascript problem). The only line of code I'm writing is therefore: webBrowser1.Url = new Uri(@"http://wiki.allegro.cc/pub/f/fb/Grozilla.svg"); This SVG file loads fine if I browse directly to the link with IE; the errors I get via my test app are: line 2, char 1, error: Invalid character, followed by line 1, char 1, error: Object expected (assuming I answer yes to the prompt to 'continue running scripts on this page'). I'm using IE 7.0.5730.13, Adobe SVG Viewer 3.03 build 94, Visual Studio 2008. Can anyone replicate this? Has anyone seen it/got any idea how to fix it? (edit: previously setting the URL in the constructor for the purposes of the example, but this raised the question of whether or not the control had finished initialising, so have changed the example to use a button - the problem still occurs. This bug originally appeared in production code so the example program I wrote was an attempt to isolate the issue and reproduce it as simply as possible.) (edit 2: having tested on several different machines, this problems seems to be related to IE7 - run IE6, and everything works fine.)

  • Passing data structures to different threads

    - by Robb
    I have an application that will be spawning multiple threads. However, I feel there might be an issue with threads accessing data that they shouldn't be. I'm relatively new to threading so bare with me. Here is the structure of the threaded application (sorry for the crudeness): MainThread / \ / \ / \ Thread A Thread B / \ / \ / \ / \ / \ / \ Thread A_1 Thread A_2 Thread B_1 Thread B_2 Under each lettered thread (which could be many), there will only be two threads and they are fired of sequentially. The issue i'm having is I'm not entirely sure how to pass in a datastructure into these threads. So, the datastructure is created in MainThread, will be modified in the lettered thread (Thread A, etc) specific to that thread and then a member variable from that datastructure is sent to Letter_Numbered threads. Currently, the lettered thread class has a member variable and when the class is constructed, the datastructure from mainthread is passed in by reference, invoking the copy constructor so the lettered thread has it's own copy to play with. The lettered_numbered thread simply takes in a string variable from the data structure within the lettered thread. My question is, is this accceptable? Is there a much better way to ensure each lettered thread gets its own data structure to play with? Sorry for the somewhat poor explanation, please leave comments and i'll try to clarify.

  • Java: Implement own message queue (threadsafe)

    - by derMax
    The task is to implement my own messagequeue that is thread safe. My approach: public class MessageQueue { /** * Number of strings (messages) that can be stored in the queue. */ private int capacity; /** * The queue itself, all incoming messages are stored in here. */ private Vector<String> queue = new Vector<String>(capacity); /** * Constructor, initializes the queue. * * @param capacity The number of messages allowed in the queue. */ public MessageQueue(int capacity) { this.capacity = capacity; } /** * Adds a new message to the queue. If the queue is full, it waits until a message is released. * * @param message */ public synchronized void send(String message) { //TODO check } /** * Receives a new message and removes it from the queue. * * @return */ public synchronized String receive() { //TODO check return "0"; } } If the queue is empty and I call remove(), I want to call wait() so that another thread can use the send() method. Respectively, I have to call notifyAll() after every iteration. Question: Is that possible? I mean does it work that when I say wait() in one method of an object, that I can then execute another method of the same object? And another question: Does that seem to be clever?

  • How can I check if a user has written his username and password correctly?

    - by Sergio Tapia
    I'm using a Linq-to-SQL class called Scans.dbml. In that class I've dragged a table called Users (username, password, role) onto the graphic area and now I can access User object via a UserRepository class: using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Scanner.Classes { public class UserRepository { private ScansDataContext db = new ScansDataContext(); public User getUser(string username) { return db.Users.SingleOrDefault(x => x.username == username); } public bool exists(string username) { } } } Now in my Login form, I want to use this Linq-to-SQL goodness to do all the data related activities. UserRepository users = new UserRepository(); private void btnLogin_Click(object sender, EventArgs e) { loginToSystem(); } private void loginToSystem() { if (users.getUser(txtUsername.Text)) { } //If txtUsername exists && User.password == Salt(txtPassword) //then Show.MainForm() with User.accountType in constructor to set permissions. } I need help with verifying that a user exists && that that users.password is equal to SALT(txtpassword.text). Any guidance please?

  • how to parametrize an import in a View?

    - by Gianluca Colucci
    Hello everybody, I am looking for some help and I hope that some good soul out there will be able to give me a hint :) In the app I am building, I have a View. When an instance of this View gets created, it "imports" (MEF) the corresponding ViewModel. Here some code: public partial class ContractEditorView : Window { public ContractEditorView () { InitializeComponent(); CompositionInitializer.SatisfyImports(this); } [Import(ViewModelTypes.ContractEditorViewModel)] public object ViewModel { set { DataContext = value; } } } and here is the export for the ViewModel: [PartCreationPolicy(CreationPolicy.NonShared)] [Export(ViewModelTypes.ContractEditorViewModel)] public class ContractEditorViewModel: ViewModelBase { public ContractEditorViewModel() { _contract = new Models.Contract(); } } Now, this works if I want to open a new window to create a new contract... But it does not if I want to use the same window to edit an existing contract... In other words, I would like to add a second construct both in the View and in the ViewModel: the original constructor would accept no parameters and therefore it would create a new contract; the new construct - the one I'd like to add - I'd like to pass an ID so that I can load a given entity... What I don't understand is how to pass this ID to the ViewModel import... Thanks in advance, Cheers, Gianluca.

  • MEF and ASP.NET MVC

    - by denis_n
    I want to use MEF with asp.net mvc. I wrote following controller factory: public class MefControllerFactory : DefaultControllerFactory { private CompositionContainer _Container; public MefControllerFactory(Assembly assembly) { _Container = new CompositionContainer(new AssemblyCatalog(assembly)); } protected override IController GetControllerInstance(RequestContext requestContext, Type controllerType) { if (controllerType != null) { var controllers = _Container.GetExports<IController>(); var controllerExport = controllers.Where(x => x.Value.GetType() == controllerType).FirstOrDefault(); if (controllerExport == null) { return base.GetControllerInstance(requestContext, controllerType); } return controllerExport.Value; } else { throw new HttpException((Int32)HttpStatusCode.NotFound, String.Format( "The controller for path '{0}' could not be found or it does not implement IController.", requestContext.HttpContext.Request.Path ) ); } } } In Global.asax.cs I'm setting my controller factory: protected void Application_Start() { AreaRegistration.RegisterAllAreas(); RegisterRoutes(RouteTable.Routes); ControllerBuilder.Current.SetControllerFactory(new MefControllerFactory.MefControllerFactory(Assembly.GetExecutingAssembly())); } I have an area: [Export(typeof(IController))] [PartCreationPolicy(CreationPolicy.NonShared)] public class HomeController : Controller { private readonly IArticleService _articleService; [ImportingConstructor] public HomeController(IArticleService articleService) { _articleService = articleService; } // // GET: /Articles/Home/ public ActionResult Index() { Article article = _articleService.GetById(55); return View(article); } } IArticleService is an interface. There is a class which implements IArticleService and Exports it. It works. Is this everything what I need for working with MEF? How can I skip setting PartCreationPolicy and ImportingConstructor for controller? I want to set my dependencies using constructor. When PartCreationPolicy is missing, I get following exception: A single instance of controller 'MvcApplication4.Areas.Articles.Controllers.HomeController' cannot be used to handle multiple requests. If a custom controller factory is in use, make sure that it creates a new instance of the controller for each request.

  • Is there a way to automaticly call all versions of an inherited method?

    - by Eric
    I'm writing a plug-in for a 3D modeling program. I have a custom class that wraps instances of elements in the 3D model, and in turn derives it's properties from the element it wraps. When the element in the model changes I want my class(es) to update their properties based on the new geometry. In the simplified example below. I have classes AbsCurveBasd, Extrusion, and Shell which are all derived from one another. Each of these classes implement a RefreshFromBaseShape() method which updates specific properties based on the current baseShape the class is wrapping. I can call base.RefreshFromBaseShape() in each implementation of RefreshFromBaseShape() to ensure that all the properties are updated. But I'm wondering if there is a better way where I don't have to remember to do this in every implementation of RefershFromBaseShape()? For example because AbsCurveBased does not have a parameterless constructor the code wont even compile unless the constructors call the base class constructors. public abstract class AbsCurveBased { internal Curve baseShape; double Area{get;set;} public AbsCurveBased(Curve baseShape) { this.baseShape = baseShape; RefreshFromBaseShape(); } public virtual void RefreshFromBaseShape() { //sets the Area property from the baseShape } } public class Extrusion : AbsCurveBased { double Volume{get;set;} double Height{get;set;} public Extrusion(Curve baseShape):base(baseShape) { this.baseShape = baseShape; RefreshFromBaseShape(); } public override void RefreshFromBaseShape() { base.RefreshFromBaseShape(); //sets the Volume property based on the area and the height } } public class Shell : Extrusion { double ShellVolume{get;set;} double ShellThickness{get;set;} public Shell(Curve baseShape): base(baseShape) { this.baseShape = baseShape; RefreshFromBaseShape(); } public void RefreshFromBaseShape() { base.RefreshFromBaseShape(); //sets this Shell Volume from the Extrusion properties and ShellThickness property } }

  • Extend the bootstrap-typeahead in order to take an object instead of a string

  • View Models (ViewData), UserControls/Partials and Global variables - best practice?

    - by elado
    Hi I'm trying to figure out a good way to have 'global' members (such as CurrentUser, Theme etc.) in all of my partials as well as in my views. I don't want to have a logic class that can return this data (like BL.CurrentUser) I do think it needs to be a part of the Model in my views So I tried inheriting from BaseViewData with these members. In my controllers, in this way or another (a filter or base method in my BaseController), I create an instance of the inheriting class and pass it as a view data. Everything's perfect till this point, cause then I have my view data available on the main View with the base members. But what about partials? If I have a simple partial that needs to display a blog post then it looks like this: <%@ Control Language="C#" AutoEventWireup="true" Inherits="ViewUserControl<Post>" %> and simple code to render this partial in my view (that its model.Posts is IEnumerable<Post>): <%foreach (Post p in this.Model.Posts) {%> <%Html.RenderPartial("Post",p); %> <%}%> Since the partial's Model isn't BaseViewData, I don't have access to those properties. Hence, I tried to make a class named PostViewData which inherits from BaseViewData, but then my containing views will have a code to actually create the PostViewData in them in order to pass it to the partial: <%Html.RenderPartial("Post",new PostViewData { Post=p,CurrentUser=Model.CurrentUser,... }); %> Or I could use a copy constructor <%Html.RenderPartial("Post",new PostViewData(Model) { Post=p }); %> I just wonder if there's any other way to implement this before I move on. Any suggestions? Thanks!

  • Memory leak, again!

    - by Dave
    A couple of weeks ago I was having trouble with memory leaks associated with a ContextMenuStrip. That problem was fixed. See that question here Now I'm having similar issues with ToolStrip controls. As in the previous problem, I'm creating a large number of UserControls and adding them to a FlowLayoutPanel. Each control creates a ToolStrip for itself in its constructor. When a control is removed from the FlowLayoutPanel (the only reference to the control), it seems memory for the ToolStrip is not being released. However when I comment out the code that creates the ToolStrip the memory leak doesn't happen. Is this the same sort of issue as the previous one - I need to set the ToolStrip to null? I don't see how that could be since this time the control is creating the strip itself, and all the button events etc are handled inside it. So shouldn't everything be GC'd when the control is no longer referenced? EDIT: As to the comments, the thing I don't understand is originally I was "making" my own toolstrip out of a panel and some labels. The labels were used as buttons. No memory leaks occurred this way. The only thing I've changed is using a proper ToolStrip with proper buttons in place of the panel, but all the event handlers are wired the same way. So why is it now leaking memory?

  • Strange GWT serialization exception when overiding method of serialized object

    - by Flueras Bogdan
    Hi there! I have a GWT serializable class, lets call it Foo. Foo implements IsSerializable, has primitive and serializable members as well as other transient members and a no-arg constructor. class Foo implements IsSerializable { // transient members // primitive members public Foo() {} public void bar() {} } Also a Service which handles RPC comunication. // server code public interface MyServiceImpl { public void doStuff(Foo foo); } public interface MyServiceAsync { void doStuff(Foo foo, AsyncCallback<Void> async); } How i use this: private MyServiceAsync myService = GWT.create(MyService.class); Foo foo = new Foo(); ... AsyncCallback callback = new new AsyncCallback {...}; myService.doStuff(foo, callback); In the above case the code is running, and the onSuccess() method of callback instance gets executed. But when I override the bar() method on foo instance like this: Foo foo = new Foo() { public void bar() { //do smthng different } } AsyncCallback callback = new new AsyncCallback {...}; myService.doStuff(foo, callback); I get the GWT SerializationException. Please enlighten me, because I really don't understand why.

  • cookie name is truncated in Servlet 3.0 HttpServletRequest (Glassfish V3)

    - by idplmal
    I'm porting our Web authentication/authorization middleware for use in containers implementing the new servlet 3.0 API (Glassfish V3 in this case). The middleware pulls cookies from the HttpServletRequest filtering on cookies with names of the form "DACS:FEDERATION::JURISDICTION:username". This works fine in the version 2.5 servlet API but is broken in 3.0. The cookie names in 3.0 are being truncated at the first ":" in the name. I understand that the servlet 3.0 implementation defaults to RFC 2109 cookies which are more restrictive about cookie names than the old Netscape spec (":" is among the characters not allowed in RFC 2109 cookie names). Digging into the servlet 3.0 source code, it appears that the use of RFC2109 names can be disabled by setting a System property "org.glassfish.web.rfc2109.cookie_names_enforced" to false. I've tried this to no avail. But besides that, the code that uses checks cookie names is in the constructor for Cookie, and it would appear that the truncation is occurring elsewhere. So - finally - the question. Have others bumped into such issues in the servlet 3.0 API and have you found a work around?

  • Subscribe to the Button's events into a custom control

    - by ThitoO
    Do you know how can I subscribe to an event of the base of my customControl ? I've a custom control with some dependency properties : public class MyCustomControl : Button { static MyCustomControl () { DefaultStyleKeyProperty.OverrideMetadata( typeof( MyCustomControl ), new FrameworkPropertyMetadata( typeof( MyCustomControl ) ) ); } public ICommand KeyDownCommand { get { return (ICommand)GetValue( KeyDownCommandProperty ); } set { SetValue( KeyDownCommandProperty, value ); } } public static readonly DependencyProperty KeyDownCommandProperty = DependencyProperty.Register( "KeyDownCommand", typeof( ICommand ), typeof( MyCustomControl ) ); public ICommand KeyUpCommand { get { return (ICommand)GetValue( KeyUpCommandProperty ); } set { SetValue( KeyUpCommandProperty, value ); } } public static readonly DependencyProperty KeyUpCommandProperty = DependencyProperty.Register( "KeyUpCommand", typeof( ICommand ), typeof( MyCustomControl ) ); public ICommand KeyPressedCommand { get { return (ICommand)GetValue( KeyPressedCommandProperty ); } set { SetValue( KeyPressedCommandProperty, value ); } } public static readonly DependencyProperty KeyPressedCommandProperty = DependencyProperty.Register( "KeyPressedCommand", typeof( ICommand ), typeof( MyCustomControl ) ); } And I whant to subscribe to Button's events (like MouseLeftButtonDown) to run some code in my customControl. Do you know how can I do something like this in the constructor ? static MyCustomControl() { DefaultStyleKeyProperty.OverrideMetadata( typeof( MyCustomControl ), new FrameworkPropertyMetadata( typeof( MyCustomControl ) ) ); MouseLeftButtonDownEvent += (object sender, MouseButtonEventArgs e) => "something"; } Thanks for you help

  • .Net Entity objectcontext thread error

    - by Chris Klepeis
    I have an n-layered asp.net application which returns an object from my DAL to the BAL like so: public IEnumerable<SourceKey> Get(SourceKey sk) { var query = from SourceKey in _dataContext.SourceKeys select SourceKey; if (sk.sourceKey1 != null) { query = from SourceKey in query where SourceKey.sourceKey1 == sk.sourceKey1 select SourceKey; } return query.AsEnumerable(); } This result passes through my business layer and hits the UI layer to display to the end users. I do not lazy load to prevent query execution in other layers of my application. I created another function in my DAL to delete objects: public void Delete(SourceKey sk) { try { _dataContext.DeleteObject(sk); _dataContext.SaveChanges(); } catch (Exception ex) { Debug.WriteLine(ex.Message + " " + ex.StackTrace + " " + ex.InnerException); } } When I try to call "Delete" after calling the "Get" function, I receive this error: New transaction is not allowed because there are other threads running in the session This is an ASP.Net app. My DAL contains an entity data model. The class in which I have the above functions share the same _dataContext, which is instantiated in my constructor. My guess is that the reader is still open from the "Get" function and was not closed. How can I close it?

  • Why won't SWFUpload execute the upload.aspx code, and why is it saving all files to the root directo

    - by Nathan Fast
    I am using SWFUpload v2.2. In IE (8):   If I upload a very tiny file (16kb):      1) The file appears in the root directory where upload.aspx is located.      2) Page_Load on upload.aspx.cs is executed.      3) The file is actually processed by the Page_Load procedure, and the processed file is saved in the correct location.   If I upload a normal file (1.5 MB):      1) The file appears in the root directory where upload.aspx is located. In Firefox (3.5.7):   No matter what size the file is, it:      1) The file appears in the root directory where upload.aspx is located. I have maxRequestLength="30000" executionTimeout="3000" in the web.config just to be sure. In the setting object for the constructor I have:   file_size_limit: "10 MB",   file_types: ".",   file_types_description: "All Files", So my questions are:   How is the file getting saved in the root directory (and why)?   Why does Page_Load only execute when I am using IE and uploading very tiny files?
