  • ASP.NET Bind to IEnumerable

    - by JFoulkes
    Hi, I'm passing a the type IEnumerable to my view, and for each item I output a html.textbox to enter the details into. When I post this back to my controller, the collection is empty and I can't see why. public class Item { public Order Order { get; set; } public string Title { get; set; } public double Price { get; set; } } My Get method: public ActionResult AddItems(Order order) { Item itemOne = new Item { Order = order }; Item itemTwo = new Item { Order = order, }; IList<Item> items = new List<Item> { itemOne, itemTwo }; return View(items); } The View: <% int i = 0; foreach (var item in Model) { %> <p> <label for="Title">Item Title:</label> <%= Html.TextBox("items[" + i + "].Title") %> <%= Html.ValidationMessage("items[" + i + "].Title", "*")%> </p> <p> <label for="Price">Item Price:</label> <%= Html.TextBox("items[" + i + "].Price") %> <%= Html.ValidationMessage("items[" + i + "].Price", "*")%> </p> <% i++; } %> The POST method: [AcceptVerbs(HttpVerbs.Post)] public ActionResult AddItems(IEnumerable<Item> items) { try { return RedirectToAction("Index"); } catch { return View(); } } At the moment i just have a breakpoint on the post method to check what i'm gettin back.

  • I'm having trouble spacing a menu control in an ASP.NET page. Is my solution the correct way to do t

    - by pkiyan
    Hey, I added a menu control to my page that is displayed vertically. I couldn't find a way to add spaces (I'd like about 5px.) between the menu items, so I just did something similar to this: <asp:Menu ID="Menu1" runat="server" BackColor="ActiveBorder"> <Items> <asp:MenuItem NavigateUrl="~/About.aspx" Text="One" /> </Items> </asp:Menu> <p></p> <asp:Menu ID="Menu2" runat="server" BackColor="ActiveBorder"> <Items> <asp:MenuItem NavigateUrl="~/Default.aspx" Text="Two" /> </Items> </asp:Menu> I just created multiple menu controls with a single menu item control in them, and placed a break between the menu controls. This seems very wrong to me, but I could not figure out another way. Also, this is a bit off subject, but is it okay to use empty paragraph tags as line breaks?(sometimes a br tag is too much) Thanks..

  • jQuery e.target bubbling best practice ?

    - by olouv
    In my heavy-ajax code, i always bind "click" the body tag & act depending on $(e.target) & using $.fn.hasClass(). However when i click on an anchor that has a </span> tag inside, my $(e.target) equals this node, and not the parent anchor as i would like it to. From now on, i have used this trick (var $t = $(e.target);) : /** bubbling **/ if($t.get(0).tagName !== "A" && $t.get(0).tagName !== "AREA") { $t = $t.parent("a"); if(empty($t)) return true; //else console.log("$t.bubble()", $t); } It feels wrong somehow... Do you have any better implementation ? $.fn.live() does not solve my issue as it still returns the span as the target. Moreover i'm looking for speed (running on atom-based touch devices) & live appeared to be way slower (twice) : http://jsperf.com/bind-vs-click/3 In fact, as @Guffa pointed, using $.fn.live() solves the span bubbling issue as i don't need the event.target anymore. I guess there is no other "right" answer here (using bind).

    - by f0rz
    Hi ! I have come to a problem, wich I have no idea how to solve. Can anyone think outside the box and point me to right directions? I would be very thankfull ! The problem. I have a UITableView containing a first row wich is always the same (a empty row with repeating background) Next rows are bounch of dynamic data rows. I have set the yellow background on my UITableView in IBuilder, My cells (except first row) have white background with code: UIView* backgroundView = [ [ [ UIView alloc ] initWithFrame:CGRectZero ] autorelease ]; backgroundView.backgroundColor = [UIColor colorWithRed: 0.96078431372549 green: 0.96078431372549 blue: 0.96078431372549 alpha: 1.0]; cell.backgroundView = backgroundView; for ( UIView* view in cell.contentView.subviews ) { view.backgroundColor = [ UIColor clearColor ]; } The example yellow background, I only want to be showed at the top. As u see img example below. The thing is I dont want to have yellow background under the last datarow, I want to contain same white color I have on the cells. This should be white as the cells. Not yellow. Thank u for your time. Regards

  • Problems running XNA game on 64-bit Windows 7

    - by Tesserex
    I'm having problems getting my game engine to run on my brother's machine, which is running 64-bit Windows 7. I'm developing on 32-bit XP SP2. My app uses XNA, FMOD.NET, and another dll I wrote entirely in C#. Everything is targeted to x86, not AnyCPU. I've read that this is required for XNA to work because there is no 64-bit xna framework. I recompiled FMOD.NET as x86 as well and made sure to be using the 32-bit version of the native dll. So I don't see any problems there. However when he tries to run my app, it gives an error which is mysterious, but not unheard of. A FileNotFoundException with an empty file name, and the top of the stack trace is in my main form constructor. The message is The specified module could not be found. (Exception from HRESULT: 0x8007007E) I found some threads online about this error, all with very vague, mixed, and fuzzy responses that don't really help me. Most remind people to target x86. Some say check that they have all the dlls necessary. I gave my brother Microsoft.Xna.Framework.dll, but does he need to install the entire XNA redistributable package? When I take everything I sent him and stick it in a random directory, it still runs fine for me. I developed the game in VS2008, not in game studio, using XNA 3.0 and a Windows Forms control that uses XNA drawing which I found in an msdn tutorial. I would also like to avoid requiring a full installer if possible. Any insight? Please?

  • lock shared data using c#

    - by menacheb
    Hi, I have a program (C#) with a list of tests to do. Also, I have two thread. one to add task into the list, and one to read and remove from it the performed tasks. I'm using the 'lock' function each time one of the threads want to access to the list. Another thing I want to do is, if the list is empty, the thread who need to read from the list will sleep. and wake up when the first thread add a task to the list. Here is the code I wrote: ... List<String> myList = new List(); Thread writeThread, readThread; writeThread = new Thread(write); writeThread.Start(); readThraed = new Thread(read); readThread.Start(); ... private void write() { while(...) { ... lock(myList) { myList.Add(...); } ... if (!readThread.IsAlive) { readThraed = new Thread(read); readThread.Start(); } ... } ... } private void read() { bool noMoreTasks = false; while (!noMoreTasks) { lock (MyList)//syncronize with the ADD func. { if (dataFromClientList.Count > 0) { String task = myList.First(); myList.Remove(task); } else { noMoreTasks = true; } } ... } readThread.Abort(); } Apparently I did it wrong, and it's not performed as expected (The readTread does't read from the list). Does anyone know what is my problem, and how to make it right? Many thanks,

    hey guys i have a textfile i have divided it into 4 parts. i want to search each part for the words that appear in each part and score that word exmaple welcome to the national basketball finals,the basketball teams here today have come a long way. without much delay lets play basketball. i will want to return national = 1 as it appears only in one part etc am working on determining text context using word position. am working with c# and not very good in text processing basically if a word appears in the 4 sections it scores 4 if a word appears in the 3 sections it scores 3 if a word appears in the 2 sections it scores 2 if a word appears in the 1 section it scores 1 thanks in advance so far i have this var s = "welcome to the national basketball finals,the basketball teams here today have come a long way. without much delay lets play basketball. "; var numberOfParts = 4; var eachPartLength = s.Length / numberOfParts; var parts = new List<string>(); var words = Regex.Split(s, @"\W").Where(w => w.Length > 0); // this splits all words, removes empty strings var wordsIndex = 0; for (int i = 0; i < numberOfParts; i++) { var sb = new StringBuilder(); while (sb.Length < eachPartLength && wordsIndex < words.Count()) { sb.AppendFormat("{0} ", words.ElementAt(wordsIndex)); wordsIndex++; } // here you have the part Response.Write("[{0}]"+ sb); parts.Add(sb.ToString()); var allwords = parts.SelectMany(p => p.Split(' ').Distinct()); var wordsInAllParts = allwords.Where(w => parts.All(p => p.Contains(w))).Distinct();

  • php sessions in database only writing part of information to the table...

    - by Ronedog
    I'm having difficulty figuring out what's going on here, hoping some one can help me out. I have been using php, mysql storing my session information in the database. The app is only running on localhost, vista. In the php.ini file I commented out the "session.save_handler = files" line and am using a php class to handle the session writes/reads, etc. My login process is this: Submit login credentials via login.php. login.php calls loginprocess.php. loginprocess.php verifies user, and if valid starts a new session and adds data to the session vars, then it redirects to index.php. Here's the problem. the loginprocess.php page has a bunch of session vars that get set like $_SESSION['account_id'] = $account_id; etc. but when I go to index.php and do a var_dump($_SESSION) it just says "array() empty". However, if I do a var_dump($_SESSION) in loginprocess.php, just before the redirection line header("Location: ../index.php"); then it shows all the data in the session variable. If I look in the database where the session information is stored, there is data in the session_id field, created_ts field, and expires field, but the session_data field has nothing inside of it and in the past this is the field where all my session data was stored. How could I be able to var_dump the session in loginprocess.php, but the data not exist in the db table, is it using some kind of caching? I cleared my cookies, etc...but no change. Why is the session_id, being written to the table, but the actual session data is not? Any ideas are appreciated. Thanks.

  • How to display only one letter in Flex Text Layout Framework ContainerController?

    - by rattkin
    I'm trying to implement dropped initials feature into my Flex application. Since Text Layout Framework does not support floating, the only known solution is to create additional containers that will be linked together, displaying the same textflow. Width and positioning of these containers has to be set in such a way that it will pretend that it's float. I'm using the same solution for dropped initials. Basically, I'm creating three containers, one for the initial letter (first letter in text flow), the other for text floating around, and the 3rd one to display text below these two. All these containers share one textflow. I have big issues with forcing controller to display only one letter from the text flow, and size it accordingly, so that it wont take any unnecessary aditional space and won't get any more text into it. Using ContainerController.getContentBounds() returns me size of whole sprite of the letter (with ascent/descent empty parts), not the height/width of the actual rendered letter. I'm using textFlow.flowComposer.getLineAt(0).getTextLine().getAtomBounds(0), but i think it's still not right. Also, even if I set container for this dimensions, it sometimes display additional text in it, especially for bigger fonts. See screen : Also, if I set width to just 1px less that contentBounds, things are going crazy, containers are moved around, positioned with big margins, etc. How should I solve this? Is it a bug in TLF / Player? Can I fix it somehow? Can I detect the size of the letter, or make containercontroller autosize to fit just one letter only?

  • How to make that the LanguageBinder take precedence over the DynamicBinder

    - by rudimenter
    Hi I Have a class which implement IDynamicMetaObjectProvider I implement the BindGetMember Method from DynamicMetaObject. Now when i Generate a dynamic Object and Access a property every call gets implicit passed through the BindGetMember Method. I want that at first the language Binder get his chance before my code comes in. It is somehow doable with "binder.FallbackGetMember" but i am not sure how the expression has to look like. I call here dynamic com=CommandFactory.GetCommand(); com.testprop; //expected: "test"; but "test2" comes back public class Command : System.Dynamic.IDynamicMetaObjectProvider { public string testprop { get { return "test"; } } public object GetValue(string name) { return "test2"; } System.Dynamic.DynamicMetaObject System.Dynamic.IDynamicMetaObjectProvider.GetMetaObject(System.Linq.Expressions.Expression parameter) { return new MetaCommand(parameter, this); } private class MetaCommand : System.Dynamic.DynamicMetaObject { public MetaCommand(Expression expression, Command value) : base(expression, System.Dynamic.BindingRestrictions.Empty, value) { } public override System.Dynamic.DynamicMetaObject BindGetMember(System.Dynamic.GetMemberBinder binder) { var self = this.Expression; var bag = (Command)base.Value; Expression target; target = Expression.Call( Expression.Convert(self, typeof(Command)), typeof(Command).GetMethod("GetValue"), Expression.Constant(binder.Name) ); var restrictions = BindingRestrictions .GetInstanceRestriction(self, bag); return new DynamicMetaObject(target, restrictions); } #endregion } }

  • How to make NSView not clip its bounding area?

    - by Jeremy L
    I created an empty Cocoa app on Xcode for OS X, and added: - (void)applicationDidFinishLaunching:(NSNotification *)aNotification { self.view = [[NSView alloc] initWithFrame:NSMakeRect(100, 100, 200, 200)]; self.view.wantsLayer = YES; self.view.layer = [CALayer layer]; self.view.layer.backgroundColor = [[NSColor yellowColor] CGColor]; self.view.layer.anchorPoint = CGPointMake(0.5, 0.5); self.view.layer.transform = CATransform3DMakeRotation(30 * M_PI / 180, 1, 1, 1); [self.window.contentView addSubview:self.view]; } But the rotated layer's background is clipped by the view's bounding area: I thought since some version of OS X and iOS, the view won't clip the content of its subviews and will show everything inside and outside? On iOS, I do see that behavior, but I wonder why it shows up like that and how to make everything show? (I am already using the most current Xcode 4.4.1 on Mountain Lion). (note: if you try the code above, you will need to link to Quartz Core, and possibly import the quartz core header, although I wonder why I didn't import the header and it still compiles perfectly)

  • Jquery Cycle Lite plugin unable to see images that have been loaded by an AJAX call

    - by William Macdonald
    Hi, I am having problems using the jquery cycle lite plugin on some images that are added via AJAX. Here is the jquery code: $(function() { resizeWindow(); $(window).bind("resize", resizeWindow); $("#assignment-nav").accordion({ header: "h3", autoHeight: false }); $(".project").click(function() { // get the HTML and load into div $('.image-holder').empty(); var justTheNumber = $(this).attr('id').replace('project-',''); $.get("get_project_images.php", {project_id:justTheNumber}, function(data){ $('.image-holder').append(data); } ); $(".image-holder").cycle({ // Cycle plugin prev: '#prev', next: '#next', timeout: 0, speed: 250 }) }); }); My code works fine in that the IMG tags are loaded and the first image of the slide show is displayed. However the prev/next buttons don't work. When I load the images via static HTML the slideshow prev/next links works fine. (I just copied and pasted the generated HTML.) I understand I need to use something like .bind or .live to make the Cycle plugin 'see' the new images. I have tried everything I can think of but I can't make it work. What am I doing wrong ?

  • JFLAP Turing Machine shortcut problem

    - by Robert Lamb
    In JFLAP (http://jflap.org), there are some shortcuts for Turing machine transitions. One of these shortcuts allows you to transition as long as the current tape symbol isn't the indicated symbol. For example, the transition !g,x;R basically says "Take this transition if the current tape symbol is not g". So far, so good. But the transition I want is !?,~;R which basically says "Move right as long as the current symbol is not the end-of-string (empty cell) symbol". The problem is I cannot figure out how to type in "!?". The JFLAP online documentation (http://www.jflap.org/tutorial/turing/one/index.html#syntax) has this to say: The first shortcut is that there exists the option of using the “!” character to convey the meaning of “any character but this character.” For example, concerning the transition (!a; x, R), if the head encounters any character but an “a”, it will replace the character with an “x” and move right. To write the expression “!?”, just type a “1” in when inputting a command. My question is...how do I actually do what that last sentence is trying to explain to me? Thanks for your help! Robert

  • jquery clone only once

    - by tsiger
    I have a series of divs like this: <div id="available-posts"> <div class="post" id="unique_id"> <a href="#" class="addme">Add</a> Some text </div> <div class="post" id="unique_id"> <a href="#" class="addme">Add</a> Some text </div> </div> The unique_id is a different number for each of the divs. Now i have a new empty div like this <div class="related-posts"></div> And i clone items in there. The thing is that i want to check if an item is already cloned. If it is i want to stop it from being cloned again. This is how i clone items: // clone it $('.addme').live('click', function() { $(this).parents('div.thepost').clone().fadeIn('normal').appendTo('#related-posts').find('a.addme').html('Remove').removeClass('addme').addClass('removeme'); return false; }); // remove it $('.removeme').live('click', function() { $(this).parents('div.thepost').fadeOut('normal', function() {$(this).remove(); }); return false; }); In other words i want the cloned list to contain only unique items. Not for example 2 clones of the same post. *edit: i am using live coz the first list (available posts) is populated through an AJAX call.

  • DataGridView with row-specific DataGridViewComboBoxColumn contents in C# Windows Forms 3.5

    - by XXXXX
    So I have something like the following data structure (constructors omitted) class Child { public string Name { get; set; } public int Age { get; set; } } class Parent { public string Name { get; set; } public List <Child> Children { get; private set; } // never null; list never empty public Child FavoriteChild { get; set; } // never null; always a reference to a Child in Children } List < Parent > Parents; What I want to do is show a DataGridView where each row is a Parent from Parent list. Each row should have two columns: a text box showing the parent's name and a DataGridViewComboBoxColumn containing that parent's children, from which the user can select the parent's favorite child. I suppose I could do the whole thing manually, but I'd like to do all this with more-or-less standard Data Binding. It's easy enough to bind the DataGridView to the list of parents, and easy enough to bind the selected child to the FavoriteChild property. The part that's giving me difficulty is that it looks like the Combo Box column wants to bind to one data source for all the combo-box's contents on all rows. I'd like each instance of the combo box to bind to the list of each parent's children. I'm fairly new to C#/Windows Forms, so I may well be missing something obvious. Or it could be that "you can't get there from here." It's not too tough to make a separate list of all the children and filter it by parent; I'm looking into that possibility right now. Is this feasible, or is there a better way?

  • Sparse (Pseudo) Infinite Grid Data Structure for Web Game

    - by Ming
    I'm considering trying to make a game that takes place on an essentially infinite grid. The grid is very sparse. Certain small regions of relatively high density. Relatively few isolated nonempty cells. The amount of the grid in use is too large to implement naively but probably smallish by "big data" standards (I'm not trying to map the Internet or anything like that) This needs to be easy to persist. Here are the operations I may want to perform (reasonably efficiently) on this grid: Ask for some small rectangular region of cells and all their contents (a player's current neighborhood) Set individual cells or blit small regions (the player is making a move) Ask for the rough shape or outline/silhouette of some larger rectangular regions (a world map or region preview) Find some regions with approximately a given density (player spawning location) Approximate shortest path through gaps of at most some small constant empty spaces per hop (it's OK to be a bad approximation often, but not OK to keep heading the wrong direction searching) Approximate convex hull for a region Here's the catch: I want to do this in a web app. That is, I would prefer to use existing data storage (perhaps in the form of a relational database) and relatively little external dependency (preferably avoiding the need for a persistent process). Guys, what advice can you give me on actually implementing this? How would you do this if the web-app restrictions weren't in place? How would you modify that if they were? Thanks a lot, everyone!

  • Dynamic Hierarchical Javascript Object Loop

    - by user1684586
    var treeData = {"name" : "A", "children" : [ {"name" : "B", "children": [ {"name" : "C", "children" :[]} ]} ]}; THE ARRAY BEFORE SHOULD BE EMPTY. THE ARRAY AFTER SHOULD BE POPULATED DEPENDING ON THE NUMBER OF NODES NEEDED THAT WILL BE DEFINED FROM A DYNAMIC VALUE THAT IS PASSED. I would like to build the hierarchy dynamically with each node created as a layer/level in the hierarchy having its own array of nodes. THIS SHOULD FORM A TREE STRUCTURE. This is hierarchy structure is described in the above code. This code has tree level simple for demonstrating the layout of the hierarchy of values. There should be a root node, and an undefined number of nodes and levels to make up the hierarchy size. Nothing should be fixed besides the root node. I do not need to read the hierarchy, I need to construct it. The array should start {"name" : "A", "children" : []} and every new node as levels would be created {"name" : "A", "children" : [HERE-{"name" : "A", "children" : []}]}. In the child array, going deeper and deeper. Basically the array should have no values before the call, except maybe the root node. After the function call, the array should comprise of the required nodes of a number that may vary with every call. Every child array will contain one or more node values. There should be a minimum of 2 node levels, including the root. It should initially be a Blank canvas, that is no predefined array values.

  • GDI+ Rotated sub-image

    - by Andrew Robinson
    I have a rather large (30MB) image that I would like to take a small "slice" out of. The slice needs to represent a rotated portion of the original image. The following works but the corners are empty and it appears that I am taking a rectangular area of the original image, then rotating that and drawing it on an unrotated surface resulting in the missing corners. What I want is a rotated selection on the original image that is then drawn on an unrotated surface. I know I can first rotate the original image to accomplish this but this seems inefficient given its size. Any suggestions? Thanks, public Image SubImage(Image image, int x, int y, int width, int height, float angle) { var bitmap = new Bitmap(width, height); using (Graphics graphics = Graphics.FromImage(bitmap)) { graphics.TranslateTransform(bitmap.Width / 2.0f, bitmap.Height / 2.0f); graphics.RotateTransform(angle); graphics.TranslateTransform(-bitmap.Width / 2.0f, -bitmap.Height / 2.0f); graphics.DrawImage(image, new Rectangle(0, 0, width, height), x, y, width, height, GraphicsUnit.Pixel); } return bitmap; }

  • Cannot clear the form after Submit using the Validation plugin in jQuery

    - by novellino
    Hello, I an quite new to jQuery and I have a problem while trying to create a form. I am using the Validation plugin for validate the email (one the form's field). When I click the Submit button I want to call my own function because I want to save the data in an XML file. This is my button: (as I understood the plugin uses "submit" for understand the button) <input type="submit" name="submit" class="submit" id="submit_btn" value="Send"/> and here is the script for the validation: <script type="text/javascript"> $(document).ready(function() { //this is my form $("#contactForm").validate(); /*save the valid data in the xml*/ $(".submit").click(function() { var email = $("input#email").val(); var subject = $("input#subject").val(); var message = $("textarea#message").val(); if (email == "" || !$("#contactForm").valid()) { return false; } var dataString = 'email='+ email + '&subject=' + subject + '&message=' + message; //alert("DATA: " +dataString); $.ajax({ type: "POST", url: "SaveData.jsp", data: dataString, success: function(data){} }); return false; }); }); </script> In general it works ok but I have two basic problems. When I click the button in the beginning having all the form empty, I get no message for the field required. Also when the data are valid and I am doing the submit, the form does not become clear after the submit. If I deleted this script code, these actions are working properly but I can not save the data! Does anyone know what is wrong? Thanks a lot!
