• How do i parse the new wow RSS feed? (LINQ to XML)

  - by Sunzaru Sven

  The link i want to parse is here. I'm looking to parse it in "real time" so that as things happen i can send myself messages/tweets and what not. I plan on having each element of the XML from the feed as an item of a class/struct. I'm really looking for LINQ to XML examples, and a good book. I've seen other LINQ to XML articles out there, but i'm just not grasping how they work. Old SQL minds are hard to break perhaps... /shrug.

• Removing title from wp_list_cats()

  - by Alex

  I'm trying to remove/replace the title attribute on the category elements used by WordPress. I'm using WordPress 2.9.1, with the following code: <div id="categories"> <h3>Manufacturers</h3> <ul> <?php str_replace("title=\"View all posts filed under ","",wp_list_categories('use_desc_for_title=0&exclude=1,2,3,4,5&title_li=&hierarchical=1')); ?> </ul> </div> From what I had read this method used to work on older versions (I had never tried it though). I really don't want to hack at the interals of WordPress, or have to use a JavaScript hack, for something so straight forward. Any help is appreciated... Update below is what is created from the code above... Manufacturers Featured

• Dollar sign and/or Dash breaking Razor's parser

  - by justSteve

  the end-result i'm trying to render: <input type="radio" name="options" id="options_1" />$1 - A Not Very Expensive Chocolate <input type="radio" name="options" id="options_2" />$10 - A Kinda Expensive Chocolate <input type="radio" name="options" id="options_3" />$100 - A Really Expensive Chocolate From this code: @foreach (var o in Model.Options){ <input type="radio" name="options" id=@("options_" + @o.ID) />[email protected] - @o.Label } If i drop both the '$' and the '-' from what should be plain old text - stuff works. Adding either resulted in compiler warnings and runtime errors. I've tried the explicit syntax as described here but haven't found the right combination yet.

• SSRS and cached reports

  - by Tabloo Quijico

  Hi, I'm opening an SSRS2008 report using the http://server/reportserver/... syntax, outputting directly a PDF copy. This report has several parameters. The problem is that, despite making changes to the report, and clearing the browser's temporary files cache.. if I request the same report (i.e. same parameters) - the old report is returned. In the report execution properties, I have "Always run this report with the most recent data" and "Do not cache temporary copies of this report" selected. It's not just a case of caching data, but the entire report (including formatting, e.g. I deleted a page from the report yet it was still being shown...) and as I haven't specifically chosen to perform any caching I'm a little concerned and clearly don't fully understand what's going on! Any tips?

• Converting files to blob to save in database

  - by jimbo

  I have an old user site that we are currently updating. The site's users have previously uploaded profile pics that are stored in a directory. I am now wanting to keep these profile images in the database, (easy to backup all data) but am having trouble working out how to do it. There are a lot of tutorials talking about do ing this from files that have just been uploaded and using the tmp name etc, but how can I re-create with files that have already been uploaded? I have looked into $data = file_get_contents($filename); Which seems to create a binary file, but doesn't seem to save in database with: mysql_query("UPDATE profiles SET company_logo = mysql_real_escape_string('".$data."') WHERE id = 1 ") or die(mysql_error());

• IE 6 dropdown selection area too narrow

  - by Cool Hand Luke UK

  Hi, I have a dropdown menu with the width set to 142px however the selection area when you drop down the menu needs to be larger as it has text that exceeds this width. Firefox (and most modern browsers) is clever and extends the selection area to fit in this text. However IE 6 and unchecked newer versions of IE do not show this text and keep the selection area the same width as the dropdown unclicked. The problem lies here, how can I get IE to extend the selection area where you click the selection you want without increasing the width of the dropdown area with out the dropdown selection showing. Hope that makes sense. :D cheers (DEATH TO IE)

• What is the best solution to replace a new memory allocator in an existing code?

  - by O. Askari

  During the last few days I've gained some information about memory allocators other than the standard malloc(). There are some implementations that seem to be much better than malloc() for applications with many threads. For example it seems that tcmalloc and ptmalloc have better performance. I have a C++ application that uses both malloc and new operators in many places. I thought replacing them with something like ptmalloc may improve its performance. But I wonder how does the new operator act when used in C++ application that runs on Linux? Does it use the standard behavior of malloc or something else? What is the best way to replace the new memory allocator with the old one in the code? Is there any way to override the behavior or new and malloc or do I need to replace all the calls to them one by one?

• How do I get User.message_set messages to show up for the built in test client?

  - by Conley Owens

  I'm aware that the old Django messages framework is deprecated, but I still would like to know the answer to this. When I go to a certain url to my broswer, a message is created, I am redirected to a different page, and I see the message correctly displayed by my template. When the test client goes to the same url, the message is created, it gets a redirect, and after following the redirect there are no messages. However, no messages appear in the response (the response gotten from following the redirect). Why not?

• Linq to Entities strange deploying behavior.

  - by SO give me back my rep

  Hi I started building apps with this technology and I am facing a weird problem... on some machines I need to add theese lines to the app.config to get to work: <system.data> <DbProviderFactories> <add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory, MySql.Data, Version=6.3.0.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d" /> </DbProviderFactories> </system.data> while in other machines it runs well without theese lines.... the thing is that when I add theese lines the app wont run on machines that did not needed theese lines in the firs place, and I would like not to publish to versions of the app, is there a way to solve this?

• Data structure name: combination array/linked list

  - by me_and

  I have come up with a data structure that combines some of the advantages of linked lists with some of the advantages of fixed-size arrays. It seems very obvious to me, and so I'd expect someone to have thought of it and named it already. Does anyone know what this is called: Take a small fixed-size array. If the number of elements you want to put in your array is greater than the size of the array, add a new array and whatever pointers you like between the old and the new. Thus you have: Static array ————————————————————————— |1|2|3|4|5|6|7|8|9|a|b|c| ————————————————————————— Linked list ———— ———— ———— ———— ———— |1|*->|2|*->|3|*->|4|*->|5|*->NULL ———— ———— ———— ———— ———— My thing: ———————————— ———————————— |1|2|3|4|5|*->|6|7|8|9|a|*->NULL ———————————— ————————————

• What git gotchas have you been caught by?

  - by Bob Aman

  The worst one I've been caught by was with git submodules. I had a submodule for a project on github. The project was unmaintained, and I wanted to submit patches, but couldn't, so I forked. Now the submodule was pointing at the original library, and I needed it to point at the fork instead. So I deleted the old submodule and replaced it with a submodule for the new project in the same commit. Turns out that this broke everyone else's repositories. I'm still not sure what the correct way of handling this situation is, but I ended up deleting the submodule, having everyone pull and update, and then I created the new submodule, and had everyone pull and update again. It took the better portion of a day to figure that out. What have other people done to accidentally screw up git repositories in non-obvious ways, and how did you resolve it?

• NServiceBus - Message Sent to and Removed from Queue, but Never Fire IHandleMessages.Handle

  - by grefly

  First let me state, today is my first day using NSesrviceBus - so I hope my question isn't too elementary. I have managed to set up Sender, Receiver, and Messages projects. When I debug the Sender, I see the messages show up in the configured queue. When I debug the Receiver, the messages are removed from the queue. However, my IHandleMessages Handle event never fires, and no Console output is displayed. I'm sure I've done something wrong (I think I may have mixed tutorials from different versions of NServiceBus) - any suggestions would be appreciated.

• Does SELECT COUNT(*) work with MySQLi prepared statements?

  - by wordman

  I'm working on a test page and am using MySQLi prepared statements in my queries after reading they make my code safe from SQL injection. I have been successful with prepared statements so far with retrieving data from my DB, that all works great. What I want to do now is count the number of galleries within a project using SELECT COUNT(*). That's it. Without using a prepared statement, my old query looked like this: // count number of galleries per project $conn = dbConnect('query'); $galNumb = "SELECT COUNT(*) FROM pj_galleries WHERE project = {$pjInfo['pj_id']}"; $gNumb = $conn->query($galNumb); $row = $gNumb->fetch_row(); $galTotal = $row[0]; But for all my reading and searching the internet, I can not find out the proper way to write this as a prepared statement. I'm no PHP whiz here, and not coding daily isn't helping my skills. If I've missed anything please ask. Many thanks!

• Python to C# Conversion of RGBA values not working

  - by clangers

  I'm currently converting some python code to C#, and I'm having an issue with the RGBA C# libraries # Original Python Code: d = math.sqrt( (x - size/2.0)**2 + (y - size/2.0)**2 ) rgbVal = int(200*d/md + 50) rgba = (0,0,0, 255 - rgbVal) img.putpixel((x,y), rgba) // My C# Code double d = Math.Sqrt(Math.Pow((x - DotSize / 2.0), 2) + Math.Pow((y - DotSize / 2.0), 2)); int rgbVal = (int) (200 * d / md + 50); Color color = Color.FromArgb(255 - rgbVal, 0, 0, 0); // ** ERROR ** img.SetPixel(x,y, color); At both instances of the code d is equal to 106 and md is equal to 53. However the resulting rgbVal value is 450. This would obviously mean that 255 - 450 is -195, which causes an error to be thrown as each individual value must be between 0 and 255. Anyone have any idea how I can fix this. Please note that the data is the same when running both the python and C# versions.

• svn: Item <folder> is out of date

  - by Tom Brito

  I'm using subclipse, and always when delete a folder in Eclipse, and try to commit it, the following errors raise: svn: Item <folder> is out of date svn: DELETE of <folder>: 409 Conflict (http://myintranet) Deleting and commiting via command line works fine, but what's wrong with doing it via subclipse? Is anyone more experiencing this problem? (I experienced this problem in Ubuntu 9.10 and 10.04; last Eclipse version; and subclipse 1.4 - as the next versions of subclipse have much more bugs) --updated: Its when I delete folders, not files

• Documentation for installing and running hadoop 2.2 on Windows

  - by user2325154

  With the latest release of Hadoop 2.2 I see that the release notes mentions that this version has significant improvements for running Hadoop on Windows. I downloaded Hadoop 2.2 yesterday and I saw lot of .cmd file alon with .sh files which ensures that this version has scripts and batch files for running Hadoop on Windows environment. However while looking at the Apache Hadoop documentation I couldn't find any step-by-step instructions on how to install and run this newer version on Windows. Besides this it looks like that the newer version has YARN architecture embedded in it and the old configurations provided on some of the tutorials online may be outdated and not applicable anymore. Is there any good documentation for Hadoop 2.2 available online ? I want it specifically for running Hadoop under Windows.

• Building an array of arrays

  - by iFloh

  I am trying to get the following loop working to fill an array of arrays: while (condition) { [itemsArray fillFromDB]; if (! [checkArray containsObject:checkFlag]) { // Add existing itemsArray to myArray if (itemsArray.count) { // add the itemsArray to myArray and create a new instance of itemsArray [myArray addObject:itemsArray]; [itemsArray release]; NSMutableArray *itemsArray = [[NSMutableArray alloc] init]; } [itemsArray addObject:myObject]; [checkArray addObject:checkFlag]; } else { [itemsArray addObject:tmpEvent]; } } However I try to shape this loop it falls over the release of itemsArray when I use release (as above), the array does not re-initialise as a new instance with alloc. Whilst expecting emptyness, the next Object is added to the old array. when I use removeAllObjects, my Array is emptied and so is the array attached to myArray. Where am I going in the wrong direction?

• Is there an off the shelf CMS that can be used as a back end for smartphone travel guide apps?

  - by eamonncarey

  I'm wondering if there's an off the shelf CMS available that is similar to something like Mobile Roadie - ie: it will allow you to create multiple versions of one application? I'm looking to develop some mobile travel guides for iPhone/Android/Blackberry etc, and rather than get a CMS built, I'd like to see if there's something out there is similar to Wordpress in that it will allow us to input text, images, Google Maps details, phone numbers, email addresses and potentially some audio/video content. If anyone knows of anything, I'd love to hear about it. Also, if you have any ideas regarding pricing, that would be extremely helpful! Thanks in advance for your assistance.

• ASP.NET MVC 2 Client Side Validation doesn't work as advertised in VS2010

  - by Daniel Crenna

  In VS2010 and ASP.NET MVC 2, it seems that client-side validation (JQuery Futures or the stock option) doesn't quite work as advertised. I'm noticing that "tabbing off" a validated element will not invoke the client-side validation as promised. For a required field, you have to tab into the element, enter something, then remove it completely, in order to trigger the required validation. That's not really what I'm after here, and I'm hoping it's just a configuration issue on my side. How do I get the validation effects from previous versions so that a previous value isn't necessary (without having to modify the client-side scripts if possible)?

• MS VC++ 6 class wizard

  - by Shane MacLaughlin

  Ok, I'm developing an application that has been in pretty much continous development over the last 16 years, from C in DOS, through various flavours of C++ and now is largely based around C++ with MFC and StingRay GUIs and various other SDKs. While I use VS 2005 for the release builds, I still use MSVC 6 for much of the GUI building, simply because ClassWizard is so much quicker in this environment than the weak equivalent tools that followed. Note that I am using ClassWizard to automatically generate code for my own user defined types (see Custom DDXs) and I like to add a lot of member variables and methods in one go. Creating them one at a time as per later versions of Visual Studio for me is a big backward step. At the same time, working with multiple IDEs is also a pain. My question is in two parts; Is there any way of getting ClassWizard to work is VS 2005 or VS 2008? Is there any drop in replacement, or alternative IDE, that provides similar levels of productivty for old C++ hacks such as myself?

• XCode iPhone OS Deployment Target Tool

  - by Trah Divad

  Problem I'm currently stuck trying to figure out what "iPhone OS Deployment Target" setting to use. I do not want to write conditional code right now, so I'd like the lowest version that runs my application fine. At first I thought it would be 2.0 as I wasn't using any 3.0 features, but then i realized that AVAudioRecorder is a 3.0 API. I don't want to be manually checking EVERY function I use in the documentation. Question Is there a tool that will check the OS availability of each functions you call in your code to figure out what the Deployment Target should be? That tool could be a good old compiler, but the latest version of the iPhone SDK does not come with the PRE-3.0 SDKs.

• Detect at runtime which country's App Store my iPhone app was downloaded from?

  - by Mike McMaster

  I have a feature in my iPhone application that, for business reasons, should only be shown/available to customers in the US. If I want to release this app to App Stores outside the US, what's the best way to figure out which country I'm in without relying on user-defined settings such as language and locale? In my mind, the ideal solution is that there's some runtime property that can tell me which App Store country the app was downloaded from, and I can take action accordingly. Looking through the docs and searching the web, I'm not coming up with anything in this department. I don't expect the solution to be 100% foolproof as far as users not being in the country they say they're from, but as close as possible would be nice. I suppose one solution would be to make a separate build for a new product on the App Store and have two versions, one for the US and one for the others, but that doesn't seem ideal. I'm hoping it can be the same product on the App Store to prevent things like fragmentation of user reviews. Thanks in advance!

• how can I "force" a branch upon the trunk, in the case I can't "reintegrate"?

  - by davka

  We created a branch from the trunk on which a major refactoring was done. Meanwhile, the trunk advanced a few revisions with some fixes. We don't want these changes on the branch, so we don't want to "catch-up" merge the trunk to the branch, because we don't want to mix the old and new code. But without this I can't reintegrate the branch back to the trunk. Is there a way to impose the branch on the trunk "as-is"? (an idea I considered is to undo ("reverse-merge") the trunk back to the revision where the branch started, and then it is safe to merge it on branch - nothing should happen. Then I can reintegrate. What do you think?) thanks!
