  • qx.ui.table.Table hangs my browser...

    - by W55tKQbuRu28Q4xv
    Hi all, I have a strange bug. I create a qx.ui.table.Table and if not all specified columns fit into window (horizontal scroll appear) my browsers (firefox 3.5.6 and chrome 5.0.344) hangs. If i just set width for window large (e.g. from 600px to 800px) - all works fine. May be I'm doing something wrong? Or how can I fix/avoid this 'strange' behaviour?

  • What is the display list in Flash 10? Array? Linked list?

    - by Typeoneerror
    I'm working on a game that has many elements on stage, so I'm looking to optimize my loops. I know that Vector is faster than looping an array, but I'm also in some cases using: while (i < numChildren) getChildAt(i) ...to update sprites. My question is when I use getChildAt, is that accessing an Array or Vector or linked list or other? Should I instead store references to my objects in a Vector and loop through that instead?

  • Sort array by two specifics values in PHP

    - by Roger
    The folks have already showed me how to sort an array by a specific value using usort and a fallback function in PHP. What if this specifc value doesn't exist and we have to use two values? in the example bellow the values [4] and [5]... In other words, I want to do this: order all objects numericaly by the fith value of each object from the highest to the lowest, and addicionally, for those objects that have the fifht value is empty (in the examplem '-'), order them by the fourth value. Array( [0] => Array( [0] => links-patrocinados [1] => adwords [2] => 0,5 [3] => R$92,34 [4] => 823000 [5] => 49500 ) [1] => Array( [0] => adwords [1] => google adwords como funciona [2] => 0,38 [3] => R$0,20 [4] => 480 [5] => 480 ) [2] => Array( [0] => links-patrocinados [1] => adword [2] => 0,39 [3] => R$58,77 [4] => 49500 [5] => 2900 ) [3] => Array( [0] => agencia [1] => agencias viagens espanholas [2] => - [3] => R$0,20 [4] => 58 [5] => - ) [4] => Array( [0] => agencia [1] => era agencia imobiliaria [2] => - [3] => R$0,20 [4] => 73 [5] => - ) )

  • non contiguous String object C#.net

    - by Kazoom
    By what i understand String and StringBuilder objects both allocate contiguous memory underneath. My program runs for days buffering several output in a String object. This sometimes cause outofmemoryexception which i think is because of non availability of contiguous memory. my string size can go upto 100MBs and i m concatenating new string frequently this causes new string object being allocated. i can reduce new string object creation by using Stringbuilder but that would not solve my problem entirely Is there an alternative to a contiguous string object?

  • Encrypt file using M2Crypto

    - by Bear
    It is known that I can read the whole file content in memory and encrypt it using the following code. contents = fin.read() cipher = M2Crypto.EVP.Cipher(alg="aes_128_cbc", key = aes_key, iv = aes_iv, op = 1) encryptedContents = cipher.update(contents) encryptedContents += cipher.final() But what if the file size is large, is there a way for me to pass the input stream to M2Crypto instead of reading the whole file first?

  • Django form and User data

    - by Dean
    I have a model that looks like this: class Client(models.Model): name = models.CharField(max_length=100, primary_key=True) user = models.ForeignKey(User) class Contract(models.Model): title = models.CharField(max_length=100, primary_key=True) start_date = models.DateField() end_date = models.DateField() description = models.TextField() client = models.ForeignKey(Client) user = models.ForeignKey(User) How can i configure a django form so that only clients associated with that user show in the field in the form? My initial thought was this in my forms.py: client = forms.ModelChoiceField(queryset=Client.objects.filter(user__username = User.username)) But it didn't work. So how else would I go about it?

  • What is the performance difference between blocks and callbacks?

    - by Don
    One of the things that block objects, introduced in Snow Leopard, are good for is situations that would previously have been handled with callbacks. The syntax is much cleaner for passing context around. However, I haven't seen any information on the performance implications of using blocks in this manner. What, if any, performance pitfalls should I look out for when using blocks, particularly as a replacement for a C-style callback?

  • jQuery MVC architecture

    Hi, what is the best way to create MVC architecture in jQuery? Should I use jQuery.extend()? jQuery.extend({ View: function(){} }); ...or jQuery Plugin?

  • How can I add a function reference to an object literal

    - by rob
    I need to add binders to DOM elements after rendering is done. Therefore I want to pass a list with (ID, callback) tuples to the rendering function so it can bind it after the rendering is done. So i would like to create a list of such objects and pass it to the rendering function: {id:'#someDOMelement', callback: someObject.someFunction} and bind it after the rendering like this: $(binders[i].id).bind('click', binders[i].callback);

  • Generate A Simple Read-Only DAL?

    - by David
    I've been looking around for a simple solution to this, trying my best to lean towards something like NHibernate, but so far everything I've found seems to be trying to solve a slightly different problem. Here's what I'm looking at in my current project: We have an IBM iSeries database as a primary repository for a third party software suite used for our core business (a financial institution). Part of what my team does is write applications that report on or key off of a lot of this data in some way. In the past, we've been manually creating ADO .NET connections (we're using .NET 3.5 and Visual Studio 2008, by the way) and manually writing queries, etc. Moving forward, I'd like to simplify the process of getting data from there for the development team. Rather than creating connections and queries and all that each time, I'd much rather a developer be able to simply do something like this: var something = (from t in TableName select t); And, ideally, they'd just get some IQueryable or IEnumerable of generated entities. This would be done inside a new domain core that I'm building where these entities would live and the applications would interface with it through a request/response service layer. A few things to note are: The entities that correspond to the database tables should be generated once and we'd prefer to manually keep them updated over time. That is, if columns/tables are added to the database then we shouldn't have to do anything. (If some are deleted, of course, it will break, but that's fine.) But if we need to use a new column, we should be able to just add it to the necessary class(es) without having to re-gen the whole thing. The whole thing should be SELECT-only. We're not doing a full DAL here because we don't want to be able to break anything in the database (even accidentally). We don't need any kind of mapping between our domain objects and the generated entity types. The domain barely covers a fraction of the data that's in there, most of it we'll never need, and we would rather just create re-usable maps manually over time. I already have a logical separation for the DAL where my "repository" classes return domain objects, I'm just looking for a better alternative to manual ADO to be used inside the repository classes. Any suggestions? It seems like what I'm doing is just enough outside the normal demand for DAL/ORM tools/tutorials online that I haven't been able to find anything. Or maybe I'm just overlooking something obvious?

  • What is the correct terminology to describe a visual display that is about the size of a living room

    - by JW
    I'm thinking that, as flat screens get bigger and cheaper it won't be too long before 'digital wallpaper'-like screens become popular in people's living rooms with a host of applications that could take advantage of this particular screen size/resolution. Is there a proper name for this size of screen? 'Wall Screen' - is too ambiguous 'Massive Screen' - is probably best reserved for something you'd put on the side of a sky scraper 'Small Screen' - nabbed by the mobiles 'Large Screen' - kind of means desktop I'm thinking of the kind of screen used in 'Minority Report'.

  • Can you make a living as a system programmer?

    - by Helper Method
    Is there still a market for C system programmers? I love Java and some of the newer JVM languages but at the same time I really enjoy low-level system programming under Unix, using C and the GNU toolchain (it makes you feel elitist ;-)). Now I wonder a) is there still a market for C system programmers and b) how much do you earn compared to an app programmer c) is it that much fun in a large scale project?
