  • Simply display RSS feed in/on aspx page

    - by Louis van Tonder
    Maybe I am being a n00b here, but for the life of me, I cant find a simple drop in type solution for displaying an rss feed inside an aspx page? I am looking for a simple solution, as when Firefox gets pointed to an rss feed, it just plainly displays it, no thrills, no fuss. I don't want to get into the xml and format it extensively. I just want a basic feed, will style it with font and a:styles. Thats it. Any ideas? EDIT: I am attempting to show a worpress "feed" inside an aspx page...

  • Scaffolding A model with an attribute of type datetime creates a 10 years range in the form

    - by b_ayan
    For a simple rails application ( 1.86 /2.3.5) , lets say I run a simple scaffold script/generate scaffold blog title:string content:text published:date When I open up the new / edit view for the blog controller in index/new.html.erb , I see that the drop down enabler for date select has a date range of 2005 - 2015 , i.e 5 years +/- I tried to change this default behavior by introducing this code f.date_select :entered, :start_year => 1970, :end_year => 2020 Apparently this has no impact to the behavior mentioned above. How do I increase the date_select range which seems to be default?

  • resetting the image in an NSView

    - by Josan
    I think this is a very simple question, but I’m new to programming so I may be going about it in a wrong-headed way. I have a basic understanding of Objective-C writing terminal applications and am teaching myself how to use the Cocoa GUI. I understand how to use IBOutlet and IBAction to connect a simple button to a method that will repeatedly send random numbers to a textfield . I understand how to add a NSView file, connect it to a custom view in interface builder and draw a path through random points in the view when the application launches. (I’ve been putting this code inside the - (void)drawRect:(NSRect)dirtyRect method that is declared when the file is created). What I can’t seem to figure out is how to connect a button to an action that will then ‘refresh’ the view – in this case repopulate it with another set of random points connected with a path. Looking at the documentation, I think I should somehow be using – (void) setNeedsDisplay(BOOL)flag but nothing I have tried so far had worked. Please tell me, what am I missing here?

  • jQuery: select checkbox when upload field is clicked

    - by Arne Stephensson
    I'm working on a CMS. When a user wants to replace an existing thumbnail image, they can upload a replacement, and check a checkbox to certify that they are indeed replacing the image. The checkbox seems necessary because otherwise the form submits a blank value (due to the presence of the upload field with no value) and wipes out the existing image without a replacement image being specified. The problem is that I keep forgetting to manually activate the checkbox and the uploaded image does not actually replace the existing one because without the checkbox being clicked, the receiving PHP file does not (by design) process the incoming filename. I suspect that users will have the same problem and I want to keep this from happening by reducing the number of steps required. One solution would be to check the checkbox with jQuery whenever the upload field is clicked. So why doesn't this work: $('#upload_field').click(function () { if ($('#replace_image').attr('checked',true)) { $('#replace_image').removeAttr('checked'); alert('Unchecked'); } else if ($('#replace_image').attr('checked',false)) { $('#replace_image').attr('checked','checked'); alert('Checked'); } });

  • Scrum stories and behind the scenes features

    - by James P.
    As I understand things, the Scrum backlog is composed of a series of Stories that represent something for the end user and this is further decomposed into Features. If this is the case, where does all the behind the scenes features go that aren't really linked to a story but are still useful? For example, say I'm making an application that catalogs the contents of a hard drive. A story wouldn't require it but having an md5 hash on each file would be a nice feature.

  • Opinions on collision detection objects with a moving scene

    - by Evan Teran
    So my question is simple, and I guess it boils down to how anal you want to be about collision detection. To keep things simple, lets assume we're talking about 2D sprites defined by a bounding box. In addition, let's assume that my sprite object has a function to detect collisions like this: S.collidesWith(other); Finally the scene is moving and "walls" in the scene can move, an object may not touch a wall. So a simple implementation might look like this (psuedo code): moveWalls(); moveSprite(); foreach(wall as w) { if(s.collidesWith(w)) { gameover(); } } The problem with this is that if the sprite and wall move towards each other, depending on the circumstances (such as diagonal moment). They may pass though each other (unlikely but could happen). So I may do this instead. moveWalls(); foreach(wall as w) { if(s.collidesWith(w)) { gameover(); } } moveSprite(); foreach(wall as w) { if(s.collidesWith(w)) { gameover(); } } This takes care of the passing through each other issue, but another rare issue comes up. If they are adjacent to each other (literally the next pixel) and both the wall and the sprite are moving left, then I will get an invalid collision since the wall moves, checks for collision (hit) then the sprite is moved. Which seems unfair. In addition, to that, the redundant collision detection feels very inefficient. I could give the player movement priority alleviating the first issue but it is still checking twice. moveSprite(); foreach(wall as w) { if(s.collidesWith(w)) { gameover(); } } moveWalls(); foreach(wall as w) { if(s.collidesWith(w)) { gameover(); } } Am I simply over thinking this issue, should this just be chalked up to "it'll happen rare enough that no one will care"? Certainly looking at old sprite based games, I often find situations where the collision detection has subtle flaws, but I figure by now we can do better :-P. What are people's thoughts?

  • CSS and control name mangling in content pages

    - by flashnik
    I have a simple website with a master-page. To set properties to elements on a content page (such as Textbox) I use CSS. In designer it works well but when I launch a site a style isn't apllied to controls. The reason is simple. To say, I have a TextBox with id="TextBox1" in content page, it is placed in ContentPlaceHolder1. In CSS file I set properties for object with id #TextBox1. When I launch a site due to master page name mangling it gets an id like ctl00_ContentPlaceHolder1_TextBox1 which is not defined in CSS file included in masterpage. What is a correct solution of this problem? Hardcoding mangled name doesn't seem to be good.

  • Setting application affinity in gdb

    - by Marcus Ahlberg
    Is there a simple way of setting the affinity of the application I'm debugging without locking gdb to the same core? The reason why I'm asking is that the application is running with real time priority and it needs to run on a single core. At the moment I use this command line taskset -c 3 gdbserver :1234 ./app.out but the application stops responding and freezes the gdb server, making debugging impossible. I suspect that the real time priority of the application prevents gdb from executing. If I start the application and then start gdb without affinity setting, then I can attach and debug the application without gdb freezing. Is there a simple way to start gdb and the application with different affinities? Or preferably: Is there a gdb command to set affinity of the child process?

  • TFS 2008 checks out code automatically on edit

    - by Jangwenyi
    I am working on a Visual Studio 2008 project that is already added to TFS server. I am not sure which settings and policies have been configured for the TFS (this is done by a separate dept, not developers) Every time I make an edit to a code file , the file is checked out automatically (without explicitly checking out the code file myself) Please help me locate this setting or policy because it is not very useful at the moment. Sometime you want to make a local change to try out something, and not necessarily check out the code....

  • Rails - Format number as currency format in the Getter

    - by daemonsy
    I am making a simple retail commerce solution, where there are prices in a few different models. These prices contribute to a total price. Imagine paying $0.30 more for selecting a topping for your yogurt. When I set the price field to t.decimal :price, precision:8, scale:2 The database stores 6.50 as 6.5. I know in the standard rails way, you call number_to_currency(price) to get the formatted value in the Views. I need to programmatically call the price field as well formatted string, i.e. $6.50 a few places that are not directly part of the View. Also, my needs are simple (no currency conversion etc), I prefer to have the price formatted universally in the model without repeated calling number_to_currency in views. Is there a good way I can modify my getter for price such that it always returns two decimal place with a dollar sign, i.e. $6.50 when it's called? Thanks in advance.

  • Simplest way to use a DatagridView with Linq to SQL

    - by Martín Marconcini
    Hi, I have never used datagrids and such, but today I came across a simple problem and decided to "databind" stuff to finish this faster, however I've found that it doesn't work as I was expecting. I though that by doing something as simple as: var q = from cust in dc.Customers where cust.FirstName == someString select cust; var list = new BindingList<Customer>(q.ToList()); return list; Then using that list in a DataGridView1.DataSource was all that I needed, however, no matter how much I google, I can't find a decent example on how to populate (for add/edit/modify) the results of a single table query into a DataGridView1. Most samples talk about ASP.NET which I lack, this is WinForms. Any ideas? I've came across other posts and the GetNewBindingList, but that doesn't seem to change much. What am I missing (must be obvious)? Thanks in advance. Martin.

  • LINQ-to-SQL vs stored procedures?

    - by scottmarlowe
    I took a look at the "Beginner's Guide to LINQ" post here on StackOverflow (http://stackoverflow.com/questions/8050/beginners-guide-to-linq), but had a follow-up question: We're about to ramp up a new project where nearly all of our database op's will be fairly simple data retrievals (there's another segment of the project which already writes the data). Most of our other projects up to this point make use of stored procedures for such things. However, I'd like to leverage LINQ-to-SQL if it makes more sense. So, the question is this: For simple data retrievals, which approach is better, LINQ-to-SQL or stored procs? Any specific pro's or con's? Thanks.

  • Partioning with Hibernate

    - by Alex
    Hello, We have a requirement to delete data in the range of 200K from database everyday. Our application is Java/JEE based using Oracle DB and Hibernate ORM tool. We explored various options like Hibernate batch processing Stored procedure Database partitioning Our DBA suggests database partitioning is the best way to go, so we can easily recreate and drop the partitioned table everyday. Now the issue is we have 2 kinds of data, one which we want to delete everyday and the other which we want to keep it. Suppose this data is stored in table "Trade". Now with partitioning, we have 2 tables "Trade". We have already existing Hibernate based DAO layer to fetch/store trades from/to DB. When we decide to partition the database, how can we control the trades to go in which of the two tables through hibernate. Basically I want , the trades need to be deleted by end of the day, to go in partitioned table and the trades I want to keep, in main table. Please suggest how can this be possible with Hibernate. We may add an additional column to identify the trades to be deleted but how can we ensure these trades should go to partitioned trade table using hibernate. I would appreciate if someone can suggest any better approach in case we are on wrong path.

  • How can one close html tags in vim quickly

    - by wds
    It's been a while since I've had to do any html-like code in vim, but recently I came across this again. Say I'm doing a simple bit of a html page: <html><head><title>This is a title</title></head></html> How do I write those closing tags for title, head and html down quickly? I feel like I'm missing some really simple way here that does not involve me going through writing them all down one by one. Of course I can use ^P to autocomplete the individual tag names but what gets me on my laptop keyboard is actually getting the brackets and slash right.

  • Can I use foreign key restrictions to return meaningful UI errors with PHP

    - by Shane
    I want to start by saying that I am a big fan of using foreign keys and have a tendency to use them even on small projects to keep my database from being filled with orphaned data. On larger projects I end up with gobs of keys which end up covering upwards of 8 - 10 layers of data. I want to know if anyone could suggest a graceful way of handling 'expected errors' from the MySQL database in a way that I can construct meaningful messages for the end user. I will explain 'expected errors' with an example. Lets say I have a set of tables used for basic discussions: discussion questions responses users Hierarchically they would probably look something like this: -users --discussion ---questions ----responses When I attempt to delete a user the FKs will check discussions and if any discussion exist the deletion is restricted, deleting discussion checks questions, deleting questions checks responses. An 'expected error' in this case would be attempting to delete a user--unless they are newly created I can anticipate that one or more foreign keys will fail causing an error. What I WANT to do is to catch that error on deletion and be able to tell the end user something like 'We're sorry, but all discussions must be removed before you can delete this user...'. Now I know I can keep and maintain matching arrays in PHP and map specific errors to messages but that is messy and prone to becoming stagnant, or I could manually run a set of selects prior to attempting the deletion, but then I am doing just as much work as without using FKs. Any help here would be greatly appreciated, or if I am just looking at this completely wrong then please let me know. On a side note I generally use CodeIgniter for my application development, so if that would open up an avenue through that framework please consider that in your answers. Thanks in Advance
