  • Fill WinForms DataGridView From Anonymous Linq Query

    - by mdvaldosta
    // From my form BindingSource bs = new BindingSource(); private void fillStudentGrid() { bs.DataSource = Admin.GetStudents(); dgViewStudents.DataSource = bs; } // From the Admin class public static List<Student> GetStudents() { DojoDBDataContext conn = new DojoDBDataContext(); var query = (from s in conn.Students select new Student { ID = s.ID, FirstName = s.FirstName, LastName = s.LastName, Belt = s.Belt }).ToList(); return query; } I'm trying to fill a datagridview control in Winforms, and I only want a few of the values. The code compiles, but throws a runtime error: Explicit construction of entity type 'DojoManagement.Student' in query is not allowed. Is there a way to get it working in this manner?

  • Can you return an assignable lvalue in Scala?

    - by Alex R
    (note, lvalue is actually a term from the C grammar, I don't know what it's called in Scala!) Trying to learn Scala... this evening I'm working on an internal DSL for a dynamically scoped language that might resemble PHP syntax. My REPL is: Welcome to Scala version 2.7.6.final (Java HotSpot(TM) Client VM, Java 1.6.0). I have some made-up example code: class $(any: Any) { def update(sym: Symbol, any: Any) { println("line 2 executed");} def -(sym: Symbol) : $ = { println("line 1 executed"); return this } def update(any: Any) { println("line 3 executed");} } The following works as expected: scala var a = new $(0) a: $ = $@19238ad scala a('x) = "blah" line 2 executed On the other hand, why does the following not invoke the 1-parameter update method? scala a = 1 :6: error: type mismatch; found : Int(1) required: $ a = 1 ^ Ultimately, I would like this to work: a-'x = "blah" Thanks

  • How to do this in VB 2010 (C# to VB conversion)

    - by user203687
    I would like to have the following to be translated to VB 2010 (with advanced syntaxes) _domainContext.SubmitChanges( submitOperation => { _domainContext.Load<Customer>( _domainContext.GetCustomersQuery(), LoadBehavior.RefreshCurrent, loadOperation => { var results = _domainContext.Customers.Where( entity => !loadOperation.Entities.Contains(entity)).ToList(); results.ForEach( enitity => _domainContext.Customers.Detach(entity)); }, null); }, null); I managed to get the above with other ways (but not using anonymous methods). I would like to see all the advanced syntaxes available in VB 2010 to be applied to the above. Can anyone help me on this? thanks

  • How do you get credentials (NetworkCredential) of currently logged in user ?

    - by Ross
    Hi, I'm writing some code to utilise a 3rd party component, and I need to supply an object which implements ICredentials when I start to use it. If I write the following... var credential = new NetworkCredential("MyUsername", "MyPassword"); ...and pass "credential", it's fine. But I would like to pass the credentials of the current user (it's a Windows service, so runs as a specified user). I have tried both of the following, but neither appear to work (or return anything): NetworkCredential credential = System.Net.CredentialCache.DefaultCredentials; NetworkCredential credential = CredentialCache.DefaultNetworkCredentials; Can anyone suggest how to acquire an approriate object, which represents the credentials of the username that the service is running under ? Thanks, Ross

  • How to get image to pulse with opacity with JQuery

    - by Alex
    I am trying to get an image to change opacity smoothly over a duration of time. Here's the code I have for it. <script type="text/javascript"> pulsem(elementid){ var element = document.getElementById(elementid) jquery(element).pulse({opacity: [0,1]}, { duration: 100, // duration of EACH individual animation times: 3, // Will go three times through the pulse array [0,1] easing: 'linear', // easing function for each individual animation complete: function() { alert("I'm done pulsing!"); } }) </script> <a href="city.htm"><img src="waterloo.png" onmouseover="javascript:pulsem("waterloo")" border="0" class="env" id="waterloo"/></a> Also, is there a way for this to happen automatically without the need of a mouseover? Thanks.

  • ReadOnlyCollection or IEnumerable for exposing member collections?

    - by Erik Öjebo
    Is there any reason to expose an internal collection as a ReadOnlyCollection rather than an IEnumerable if the calling code only iterates over the collection? class Bar { private ICollection<Foo> foos; // Which one is to be preferred? public IEnumerable<Foo> Foos { ... } public ReadOnlyCollection<Foo> Foos { ... } } // Calling code: foreach (var f in bar.Foos) DoSomething(f); As I see it IEnumerable is a subset of the interface of ReadOnlyCollection and it does not allow the user to modify the collection. So if the IEnumberable interface is enough then that is the one to use. Is that a proper way of reasoning about it or am I missing something? Thanks /Erik

  • jquery boxy plugin: prevent multiple instances of the same dialog when clicking the link multiple ti

    - by Lyon
    Hi, I'm using the Boxy jQuery plugin to open dialog windows and populating it through ajax. http://onehackoranother.com/projects/jquery/boxy/ Here's my code so far: $("a.create").click(function (e) { url = $(e.target).attr('href'); Boxy.load(url, {title:'Test'}); }); This opens up a dialog alright. However, if I click the link again, another dialog will open. How can I make it such that the previously opened Boxy dialog will come into focus? I only want one instance of this dialog. I tried assigning a variable to var ele = Boxy.load(); but the variable ele returns undefined... Alas, I can't make out much from the limited Boxy documentation available. Enabling the option modal: true would prevent the user from clicking on the link multiple times, but I don't want the overlay to show. Thanks for any light you can shed on this. -Lyon

  • NodeJS and node-mongodb-native

    - by w1nk
    Just getting started with node, and trying to get the mongo driver to work. I've got my connection set up, and oddly I can insert things just fine, however calling find on a collection produces craziness. var db = new mongo.Db('things', new mongo.Server('192.168.2.6',mongo.Connection.DEFAULT_PORT, {}), {}); db.open(function(err, db) { db.collection('things', function(err, collection) { // collection.insert(row); collection.find({}, null, function(err, cursor) { cursor.each(function(err, doc) { sys.puts(sys.inspect(doc,true)); }); }); }); }); If I uncomment the insert and comment out the find, it works a treat. The inverse unfortunately doesn't hold, I receive this error: collection.find({}, null, function(err, cursor) { ^ TypeError: Cannot call method 'find' of null I'm sure I'm doing something silly, but for the life of me I can't find it...

  • Equality between two enumerables

    - by Berryl
    I have two enumerables with the exact same reference elements, and wondering why Equals wouldn't be true. As a side question, the code below to compare each element works, but there must be a more elegant way Cheers, Berryl var other = (ActivityService) obj; if (!AllAccounts.Count().Equals(other.AllAccounts.Count())) return false; for (int i = 0; i < AllAccounts.Count(); i++) { if (!AllAccounts.ElementAt(i).Equals(other.AllAccounts.ElementAt(i))) { return false; } } return true;

  • ActionScript rotated sprite's startDrag bounds

    - by TheDarkIn1978
    when assigning a bounds to a draggable sprite, it doesn't seem to take rotation of the sprite into consideration. the code below adds a sprite to the display list, rotates it 45º, and adds a MouseEvent.MOUSE_DOWN event to allow dragging. the startDrag() method's second parameter simply returns the bounds of the stage as a rectangle. however, because of the sprite's rotation, its corners can be dragged past the bounds of the stage. any thoughts? var mySprite:Sprite = new Sprite(); mySprite.graphics.beginFill(0x0000FF, 1); mySprite.graphics.drawRect(0, 0, 200, 200); mySprite.graphics.endFill(); mySprite.rotation = 45; addChild(mySprite); mySprite.addEventListener(MouseEvent.MOUSE_DOWN, dragSprite, false, 0, true); function dragSprite(evt:MouseEvent):void { evt.target.startDrag(false, spriteBounds()); }

  • Collapse Tables with specific Table ID? JavaScript

    - by medoix
    I have the below JS at the top of my page and it successfully collapses ALL tables on load. However i am trying to figure out how to only collapse tables with the ID of "ctable" or is there some other way of specifying the tables to make collapsible etc? <script type="text/javascript"> var ELpntr=false; function hideall() { locl = document.getElementsByTagName('tbody'); for (i=0;i<locl.length;i++) { locl[i].style.display='none'; } } function showHide(EL,PM) { ELpntr=document.getElementById(EL); if (ELpntr.style.display=='none') { document.getElementById(PM).innerHTML=' - '; ELpntr.style.display='block'; } else { document.getElementById(PM).innerHTML=' + '; ELpntr.style.display='none'; } } onload=hideall; </script>

  • How do you handle the fetchxml result data?

    - by Luke Baulch
    I have avoided working with fetchxml as I have been unsure the best way to handle the result data after calling crmService.Fetch(fetchXml). In a couple of situations, I have used an XDocument with LINQ to retrieve the data from this data structure, such as: XDocument resultset = XDocument.Parse(_service.Fetch(fetchXml)); if (resultset.Root == null || !resultset.Root.Elements("result").Any()) { return; } foreach (var displayItem in resultset.Root.Elements("result").Select(item => item.Element(displayAttributeName)).Distinct()) { if (displayItem!= null && displayItem.Value != null) { dropDownList.Items.Add(displayItem.Value); } } What is the best way to handle fetchxml result data, so that it can be easily used. Applications such as passing these records into an ASP.NET datagrid would be quite useful.

  • jQuery calculation plugin: show total in form field rather than text

    - by Katherine
    I'm embarrassed by the 'basicness' of this question, but after wasted hours, here goes. In an effort to do something with the jQuery Calculation plugin, I am playing with the basic example of the order form on the plugin site. I want to have the grand total as a form field,rather than text, so I can use the value. The function that calculates and shows the grand total is: function ($this){ // sum the total of the $("[id^=total_item]") selector var sum = $this.sum(); $("#grandTotal").text( // round the results to 2 digits sum.toFixed(2) ); } the total updates on keyup in: <span id="grandTotal"></span> But this does not work with: <input type="text" id="grandTotal" value=""/> Can anyone point me to what I need to add/change to make that work? To call my javascript basic would be a compliment, so please talk to me like I know nothing!

  • Java: exception-throwing class?

    I have classes DirReader and Search. The search uses DirReader. I want the search to know when DirReader throws exception. So how can I have class throwing exception? Currently, I use initCorrect -dummy var. Exception-style method may be more appropriate. Simplified Example Error $ javac ExceptionStatic.java ExceptionStatic.java:4: '{' expected public class ExceptionStatic throws Exception{ ^ 1 error Code import java.util.*; import java.io.*; // THIS PART NEEDS TO BE FIXED: public class ExceptionStatic throws Exception{ private static boolean initCorrect = false; public static String hello; static{ try{ hello = "hallo"; //some other conditionals in real code if( true) throw new Exception(); initCorrect=true; }catch(Exception e){ e.printStackTrace(); } } public static void main(String[] args){ if(initCorrect) System.out.println(hello); } }

  • JQuery live event binding prevents additional callbacks

    - by Alex Ciminian
    Hey! I was building an AJAX listing of elements in my site, with the ability to delete them (also via AJAX). The following piece of code handles the deletion: $('ul.action-menu a.delete').live('click', function () { $.post($(this).attr('href'), function (data) { var recvData = eval( '(' + data + ')' ); if ((recvData.status == 1) && (recvData.delId)) { $('#alert-' + recvData.delId).fadeOut(); } else { alert(recvData.message); } }); return false; }); This works just fine. The problem is that, for elements that were not there when the page was loaded (i.e. that were added dynamically), the post callback does not get executed and it doesn't fade out after being deleted (the AJAX call is being made, it just doesn't execute the callback). Do you have any idea why this is happening? Thanks, Alex

  • Change present working directory of a calling shell from a ruby script

    - by Erik Kastman
    I'm writing a simple ruby sandbox command-line utility to copy and unzip directories from a remote filesystem to a local scratch directory in order to unzip them and let users edit the files. I'm using Dir.mktmpdir as the default scratch directory, which gives a really ugly path (for example: /var/folders/zz/zzzivhrRnAmviuee+++1vE+++yo/-Tmp-/d20100311-70034-abz5zj) I'd like the last action of the copy-and-unzip script to cd the calling shell into the new scratch directory so people can access it easily, but I can't figure out how to change the PWD of the calling shell. One possibility is to have the utility print out the new path to stdout and then run the script as part of a subshell (i.e. cd $(sandbox my_dir) ), but I want to print out progress on the copy-and-unzipping since it can take up to 10 minutes, so this won't work. Should I just have it go to a pre-determined, easy-to-find scratch directory? Does anyone have a better suggestion? Thanks in advance for your help. -Erik

  • open_basedir vs sessions

    - by liquorvicar
    On a virtual hosting server I have the open_basedir set to .:/path/to/vhost/web:/tmp:/usr/share/pear for each virtual host. I have a client who's running WordPress and he's complaining about open_basedir errors thus: PHP WARNING: file_exists() [function.file-exists]: open_basedir restriction in effect. File(/var/lib/php/session/sess_42k7jn3vjenj43g3njorrnrmf2) is not within the allowed path(s): (.:/path/to/vhost/web:/tmp:/usr/share/pear) So the PHP session save_path isn't included in open_basedir but sessions across all sites on the server seems to be working fine apart from in this intermittent instance. I thought that perhaps the default session handler ignored open_basedir and this warning was caused by WP accessing the session file directly. However from what I can see PHP 5.2.4 introduced open_basedir checking to the session.save_path config: http://www.php.net/ChangeLog-5.php#5.2.4 (I am on PHP 5.2.13). Any ideas?

  • Using Moq at Blend design time

    - by adrian hara
    This might be a bit out there, but suppose I want to use Moq in a ViewModel to create some design time data, like so: public class SomeViewModel { public SomeViewModel(ISomeDependency dependency) { if (IsInDesignMode) { var mock = new Mock<ISomeDependency>(); dependency = mock.Object; // this throws! } } } The mock could be set up to do some stuff, but you get the idea. My problem is that at design-time in Blend, this code throws an InvalidCastException, with the message along the lines of "Unable to cast object of type 'Castle.Proxies.ISomeDependencyProxy2b3a8f3188284ff0b1129bdf3d50d3fc' to type 'ISomeDependency'." While this doesn't necessarily look to be Moq related but Castle related, I hope the Moq example helps ;) Any idea why that is? Thanks!

  • Handling two WebException's properly

    - by baron
    Hi Everyone, I am trying to handle two different WebException's properly. Basically they are handled after calling WebClient.DownloadFile(string address, string fileName) AFAIK, so far there are two I have to handle, both WebException's: The remote name could not be resolved (i.e. No network connectivity to access server to download file) (404) File not nound (i.e. the file doesn't exist on the server) There may be more but this is what I've found most important so far. So how should I handle this properly, as they are both WebException's but I want to handle each case above differently. This is what I have so far: try { using (var client = new WebClient()) { client.DownloadFile("..."); } } catch(InvalidOperationException ioEx) { if (ioEx is WebException) { if (ioEx.Message.Contains("404") { //handle 404 } if (ioEx.Message.Contains("remote name could not") { //handle file doesn't exist } } } As you can see I am checking the message to see what type of WebException it is. I would assume there is a better or a more precise way to do this? Thanks

  • Ninject : ninject.web - How to apply on a regular ASP.Net Web (!MVC)

    - by No Body
    What I am looking is something similar to the below (http://github.com/ninject/ninject.web.mvc): README.markdown This extension allows integration between the Ninject core and ASP.NET MVC projects. To use it, just make your HttpApplication (typically in Global.asax.cs) extend NinjectHttpApplication: public class YourWebApplication : NinjectHttpApplication { public override void OnApplicationStarted() { // This is only needed in MVC1 RegisterAllControllersIn("Some.Assembly.Name"); } public override IKernel CreateKernel() { return new StandardKernel(new SomeModule(), new SomeOtherModule(), ...); // OR, to automatically load modules: var kernel = new StandardKernel(); kernel.AutoLoadModules("~/bin"); return kernel; } } Once you do this, your controllers will be activated via Ninject, meaning you can expose dependencies on their constructors (or properties, or methods) to request injections.

  • Asp.Net Mvc JQuery ajax input parameters are null

    - by Dofs
    Hi, I am trying to post some data with jQuery Ajax, but the parameters in my Ajax method are null. This is simple test to send data: var dataPost = { titel: 'titel', message: 'msg', tagIds: 'hello' }; jQuery.ajax({ type: "POST", url: "Create", contentType: 'application/json; charset=utf-8', data: $.toJSON(dataPost), dataType: "json", success: function(result) { alert("Data Returned: "); } }); And my Ajax method looks like this: [HttpPost] public ActionResult Create(string title, string message, string tagIds) {... } There is something basic wrong with the data I send, but I can't figure out what. All the time the title, message and tagIds are null, so there is something wrong with the encoding, I just don't know what. Note: The jQuery.toJSON is this plugin
