  • Replicating multicolumn lists from the Django admin CSS

    - by mfalcon
    Hi, I'm developing a Django project and I've to show a multicolumn list for the different objects of a table. I like the design of the django-admin for showing list-objects so I looked at the code to see how it works. As I am a CSS begginer the code seemed a bit difficult and extensive to comprehend. Is there a simplier way to make what I want or actually the CSS code of the django-admin is the path to follow?

  • Flatten (an irregular) list of lists in Python

    - by telliott99
    Yes, I know this subject has been covered before (here, here, here, here), but AFAIK, all solutions save one choke on a list like this: L = [[[1, 2, 3], [4, 5]], 6] where the desired output is [1, 2, 3, 4, 5, 6] or perhaps even better, an iterator. The only solution I saw that works for an arbitrary nesting is from @Alabaster Codify here: def flatten(x): result = [] for el in x: if hasattr(el, "__iter__") and not isinstance(el, basestring): result.extend(flatten(el)) else: result.append(el) return result flatten(L) So to my question: is this the best model? Did I overlook something? Any problems?

  • what's faster: merging lists or dicts in python?

    - by tipu
    I'm working with an app that is cpu-bound more than memory bound, and I'm trying to merge two things whether they be sets or dicts. Now the thing is i can choose either one, but I'm wondering if merging dicts would be faster since it's all in memory? Or is it always going to be O(n), n being the size of the smaller set. The reason I asked about dicts rather than sets is because I can't convert a set to json, because that results in {key1, key2, key3} and json needs a key/value pair, so I am using a dict so json dumps returns {key1:1, key2:1, key3:1}. Yes this is wasteful, but if it proves to be faster then I'm okay with it.

  • Efficient data structure for fast random access, search, insertion and deletion

    - by Leonel
    I'm looking for a data structure (or structures) that would allow me keep me an ordered list of integers, no duplicates, with indexes and values in the same range. I need four main operations to be efficient, in rough order of importance: taking the value from a given index finding the index of a given value inserting a value at a given index deleting a value at a given index Using an array I have 1 at O(1), but 2 is O(N) and insertion and deletions are expensive (O(N) as well, I believe). A Linked List has O(1) insertion and deletion (once you have the node), but 1 and 2 are O(N) thus negating the gains. I tried keeping two arrays a[index]=value and b[value]=index, which turn 1 and 2 into O(1) but turn 3 and 4 into even more costly operations. Is there a data structure better suited for this?

  • Custom Items in Lists in C# forms?

    - by chaz
    I'm a bit new to the C#-form app developing and I want know, what's the best way around at making a control that holds a list of horizontal items. In which each of these items are horizontally ruled to it's parent control, contain a thumbnail to the left and a large text block to the right of image and a smaller text block underneath that. So basically this isn't a predefined control I can find in the toolbox. Any ideas?

  • Skip Lists -- ever used them?

    - by Head Geek
    I'm wondering whether anyone here has ever used a skip list. It looks to have roughly the same advantages as a balanced binary tree, but is simpler to implement. If you have, did you write your own, or use a pre-written library (and if so, what was its name)?

  • Predicates and Lists

    - by George
    Hello guys, I have a generic list. Some elements of this list belong to a parent element. I retrieved all these elements from a database and i want to recursively build a tree with them. So, here's what i'm thinking: Here is my predicate: public static bool FindChildren(Int32 parentId,CategoryMapping catMapping) { if (catMapping.parentId == parentId) { return true; } else { return false; } } root = list[0]; root.childrenElements = root.FindAll(FindChildren(root.id,???) I can't figure out how this would work. How can i do this kind of predicate?

  • ASP.NET AppDomain–What it is and why it’s important–Part 12 of 52 part series

    - by OWScott
    AppDomains are a silent mysterious part of ASP.NET and IIS.  It’s important for the web administrator to be aware of this building block of ASP.NET so that we can be aware of how changes to the system can affect production sites. While this series is targeted at the IIS and web administrator, this topic is useful for the ASP.NET programmer too. This is week 12 of a 52 week series on various web administration related tasks. Past and future videos can be found here.

  • AJAX 4 no ASP.NET 4 Web Application

    - by renatohaddad
    Andei fazendo uns testes no AJAX Control Toolkit 4 que deverá ser usado com o ASP.NET 4 no Visual Studio .NET 2010 e confesso que gostei muito. O link para download é http://www.asp.net/ajaxlibrary/act.ashx e todas as instruções constam no site. Notei que há diversos controles novos e um que me chamou a atenção foi o de Upload assíncrono para controlar os uploads de arquivos para o server. Vale a pena estudar um pouco estas novidades. Para quem já usava o AJAX no ASP.NET 3.5, a idéia do Toolkit é igual, exceto a adição de novos controles. Com o AJAX vc pode mudar todo o comportamento da sua aplicação WEB, requisições no server passam a ser menos frequentes, o layout ajuda e muito com os controles do AJAX. Nativamente no VS 2010 já há o AJAX que a MS suporta nativamente (ScriptManager, UpdatePanel, UpdateProgress, etc), mas vale a pena implementar alguns controles do Toolkit. Bons estudos!

  • ASP.NET AJAX and my axe!

    - by Marlon
    So, I'm seriously considering axing ASP.NET AJAX from my future projects as I honestly feel it's too bloated, and at times convoluted. I'm also starting to feel it is a dying library in the .NET framework as I hardly see any quality components from the open-source community. All the kick-ass components are usually equally bloated commercial components... It was cool at first, but now I tend to get annoyed with it more than anything else. I'm planning on switching over to the jQuery library as just about everything in ASP.NET AJAX is often easily achievable with jQuery, and, more often than not, more graceful of a solution that ASP.NET AJAX and it has a much stronger open-source community. Perhaps, it's just me, but do you feel the same way about ASP.NET AJAX? How was/is your experience working with ASP.NET AJAX?

  • How To Get Web Site Thumbnail Image In ASP.NET

    - by SAMIR BHOGAYTA
    Overview One very common requirement of many web applications is to display a thumbnail image of a web site. A typical example is to provide a link to a dynamic website displaying its current thumbnail image, or displaying images of websites with their links as a result of search (I love to see it on Google). Microsoft .NET Framework 2.0 makes it quite easier to do it in a ASP.NET application. Background In order to generate image of a web page, first we need to load the web page to get their html code, and then this html needs to be rendered in a web browser. After that, a screen shot can be taken easily. I think there is no easier way to do this. Before .NET framework 2.0 it was quite difficult to use a web browser in C# or VB.NET because we either have to use COM+ interoperability or third party controls which becomes headache later. WebBrowser control in .NET framework 2.0 In .NET framework 2.0 we have a new Windows Forms WebBrowser control which is a wrapper around old shwdoc.dll. All you really need to do is to drop a WebBrowser control from your Toolbox on your form in .NET framework 2.0. If you have not used WebBrowser control yet, it's quite easy to use and very consistent with other Windows Forms controls. Some important methods of WebBrowser control are. public bool GoBack(); public bool GoForward(); public void GoHome(); public void GoSearch(); public void Navigate(Uri url); public void DrawToBitmap(Bitmap bitmap, Rectangle targetBounds); These methods are self explanatory with their names like Navigate function which redirects browser to provided URL. It also has a number of useful overloads. The DrawToBitmap (inherited from Control) draws the current image of WebBrowser to the provided bitmap. Using WebBrowser control in ASP.NET 2.0 The Solution Let's start to implement the solution which we discussed above. First we will define a static method to get the web site thumbnail image. public static Bitmap GetWebSiteThumbnail(string Url, int BrowserWidth, int BrowserHeight, int ThumbnailWidth, int ThumbnailHeight) { WebsiteThumbnailImage thumbnailGenerator = new WebsiteThumbnailImage(Url, BrowserWidth, BrowserHeight, ThumbnailWidth, ThumbnailHeight); return thumbnailGenerator.GenerateWebSiteThumbnailImage(); } The WebsiteThumbnailImage class will have a public method named GenerateWebSiteThumbnailImage which will generate the website thumbnail image in a separate STA thread and wait for the thread to exit. In this case, I decided to Join method of Thread class to block the initial calling thread until the bitmap is actually available, and then return the generated web site thumbnail. public Bitmap GenerateWebSiteThumbnailImage() { Thread m_thread = new Thread(new ThreadStart(_GenerateWebSiteThumbnailImage)); m_thread.SetApartmentState(ApartmentState.STA); m_thread.Start(); m_thread.Join(); return m_Bitmap; } The _GenerateWebSiteThumbnailImage will create a WebBrowser control object and navigate to the provided Url. We also register for the DocumentCompleted event of the web browser control to take screen shot of the web page. To pass the flow to the other controls we need to perform a method call to Application.DoEvents(); and wait for the completion of the navigation until the browser state changes to Complete in a loop. private void _GenerateWebSiteThumbnailImage() { WebBrowser m_WebBrowser = new WebBrowser(); m_WebBrowser.ScrollBarsEnabled = false; m_WebBrowser.Navigate(m_Url); m_WebBrowser.DocumentCompleted += new WebBrowserDocument CompletedEventHandler(WebBrowser_DocumentCompleted); while (m_WebBrowser.ReadyState != WebBrowserReadyState.Complete) Application.DoEvents(); m_WebBrowser.Dispose(); } The DocumentCompleted event will be fired when the navigation is completed and the browser is ready for screen shot. We will get screen shot using DrawToBitmap method as described previously which will return the bitmap of the web browser. Then the thumbnail image is generated using GetThumbnailImage method of Bitmap class passing it the required thumbnail image width and height. private void WebBrowser_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e) { WebBrowser m_WebBrowser = (WebBrowser)sender; m_WebBrowser.ClientSize = new Size(this.m_BrowserWidth, this.m_BrowserHeight); m_WebBrowser.ScrollBarsEnabled = false; m_Bitmap = new Bitmap(m_WebBrowser.Bounds.Width, m_WebBrowser.Bounds.Height); m_WebBrowser.BringToFront(); m_WebBrowser.DrawToBitmap(m_Bitmap, m_WebBrowser.Bounds); m_Bitmap = (Bitmap)m_Bitmap.GetThumbnailImage(m_ThumbnailWidth, m_ThumbnailHeight, null, IntPtr.Zero); } One more example here : http://www.codeproject.com/KB/aspnet/Website_URL_Screenshot.aspx
