• Converting John Resig's JavaScript Templating Engine to work with PHP Templates

  - by Serhiy

  I'm trying to convert the John Resig's Templating Engine to work with PHP. Essentially what I would like to achieve is the ability to use certain Kohana Views via a JavaScript templating engine, that way I can use the same views for both a standard PHP request and a jQuery AJAX request. I'm starting with the basics and would like to be able to convert http://github.com/nje/jquery-tmpl/blob/master/jquery.tmpl.js To work with php like so... ### From This ### <li><a href="{%= link %}">{%= title %}</a> - {%= description %}</li> ### Into This ### <li><a href="<?= $link ?>"><?= $title ?></a> - <?= description ?></li> The RexEx in it is a bit over my head and it's apparently not as easy as changing the %} to ? in lines 148 to 158. Any help would be highly appreciated. I'm also not sure of how to take care of the $ difference that PHP variables have. Thanks, Serhiy

• Axis2 Class Generation

  - by Jack

  I have an instance of a derived class (called Child) that I would like to send between the client and server of my web service. However, the method that might be returning this instance, is marked as returning an instance of the parent class (called Parent). For example: public class Service{public Parent createInstanceOfParentOrChildObject();} While Child is not a parameter anywhere in the service nor is it ever specifically named as a return type (only Parent is ever named), it is nonetheless generated and returned inside certain methods (and then cast to Parent). I generated the wsdl file using Axis2 1.4.1 java2wsdl and specifying that it include this class (using the -xc parameter). I did not use Axis2 1.5.1 because it was not honoring the -xc parameter though it looks like that bug is supposedly fixed in Axis2 1.6. I even did a quick check of the generated .wsdl file to ensure that it did indeed include a definition for Child (and, of course, Parent). However, when I used wsdl2java to generate the server-side (and client-side) code, Child was not generated. How can I get wsdl2java to generate Child? I realize that I could do this by hand but I don't want to have to do this for both the client and server. I was also hoping that I could make this as easy as possible for people to use my wsdl to generate their own clients.

• Debugging Maya plug-ins: can't get output or debugger to engage

  - by brainjam

  I'm not a total beginner at Maya, but this is my first time trying to write a plug-in for it. I've downloaded the 30-day eval version of Maya2011 (32bit version on 64bit Windows 7), and have tried building a couple of plug-ins with VC 2008 Express. The first one is helloWorldCmd from the sample directory ..\devkit\plug-ins, and it basically doesn't work until you convert the line cout<<"Hello World"<<endl; to cerr<<"Hello World"<<endl;, but I can live with that. The second one is the SelectRingContext2 example from David Gould's book. The plug-in works as advertised, but I cannot get any debugging output from it. I've tried putting cout, cerr,printf, and MGlobal::displayInfo into the doIt() method, and can't get a peep. I also haven't figured out how to run the plug-in in a debugger. I'm afraid I'm missing something easy but slightly obscure, like a flag somewhere. Anybody out there have any hints? Edit: Turns out the action is happening in the redoIt() method. So I can get MGlobal::displayInfo and cerr producing output. Still don't know why cout and printf don't work, and I'm not sure how to run in the debugger. When I run maya -d (which some of the online advice says I should do) it just shows the output window but never loads the rest.

• Help with Perl persistent data storage using Data::Dumper

  - by stephenmm

  I have been trying to figure this out for way to long tonight. I have googled it to death and none of the examples or my hacks of the examples are getting it done. It seems like this should be pretty easy but I just cannot get it. Here is the code: #!/usr/bin/perl -w use strict; use Data::Dumper; my $complex_variable = {}; my $MEMORY = "$ENV{HOME}/data/memory-file"; $complex_variable->{ 'key' } = 'value'; $complex_variable->{ 'key1' } = 'value1'; $complex_variable->{ 'key2' } = 'value2'; $complex_variable->{ 'key3' } = 'value3'; print Dumper($complex_variable)."TEST001\n"; open M, ">$MEMORY" or die; print M Data::Dumper->Dump([$complex_variable], ['$complex_variable']); close M; $complex_variable = {}; print Dumper($complex_variable)."TEST002\n"; # Then later to restore the value, it's simply: do $MEMORY; #eval $MEMORY; print Dumper($complex_variable)."TEST003\n"; And here is my output: $VAR1 = { 'key2' => 'value2', 'key1' => 'value1', 'key3' => 'value3', 'key' => 'value' }; TEST001 $VAR1 = {}; TEST002 $VAR1 = {}; TEST003 Everything that I read says that the TEST003 output should look identical to the TEST001 output which is exactly what I am trying to achieve. What am I missing here? Should I be "do"ing differently or should I be "eval"ing instead and if so how? Thanks for any help...

• XML document being parsed as single element instead of sequence of nodes

  - by Rob Carr

  Given xml that looks like this: <Store> <foo> <book> <isbn>123456</isbn> </book> <title>XYZ</title> <checkout>no</checkout> </foo> <bar> <book> <isbn>7890</isbn> </book> <title>XYZ2</title> <checkout>yes</checkout> </bar> </Store> I am getting this as my parsed xmldoc: >>> from xml.dom import minidom >>> xmldoc = minidom.parse('bar.xml') >>> xmldoc.toxml() u'<?xml version="1.0" ?><Store>\n<foo>\n<book>\n<isbn>123456</isbn>\n</book>\n<t itle>XYZ</title>\n<checkout>no</checkout>\n</foo>\n<bar>\n<book>\n<isbn>7890</is bn>\n</book>\n<title>XYZ2</title>\n<checkout>yes</checkout>\n</bar>\n</Store>' Is there an easy way to pre-process this document so that when it is parsed, it isn't parsed as a single xml element?

• Selecting a multi-dimensional array in LINQ

  - by mckhendry

  I have a task where I need to translate a DataTable to a two-dimensional array. That's easy enough to do by just looping over the rows and columns (see example below). private static string[,] ToArray(DataTable table) { var array = new string[table.Rows.Count,table.Columns.Count]; for (int i = 0; i < table.Rows.Count; ++i) for (int j = 0; j < table.Columns.Count; ++j) array[i, j] = table.Rows[i][j].ToString(); return array; } What I'd really like to do is use a select statement in LINQ to generate that 2D array. Unfortunately it looks like there is no way in LINQ to select a multidimensional array. Yes, I'm aware that I can use LINQ to select a jagged array, but that's not what I want. Is my assumption correct, or is there a way to use LINQ to select a multi-dimensional array?

• How yo play rington/alarm sound in Android

  - by Federico

  I have been looking everywhere how to play a $#@&! rington/alarm sound in android. I press a button and I want to play a rington/alarm sound. I could not find a easy, strsight forward sample... YES! I already looked at Alarm clock source code... but it is not straight forward and I cannot compile it neither. I cannot make this work: Uri alert = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM); mMediaPlayer = new MediaPlayer(); mMediaPlayer.setDataSource(this, alert); final AudioManager audioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE); if (audioManager.getStreamVolume(AudioManager.STREAM_ALARM) != 0) { player.setAudioStreamType(AudioManager.STREAM_ALARM); player.setLooping(true); player.prepare(); player.start(); } I get this error 04-11 17:15:27.638: ERROR/MediaPlayerService(30): Couldn't open fd for content://settings/system/ringtone So.. please if somebody knows how to play a default rington/alarm let me know. I prefer not to upload any file. Just play a default rington. Thanks, Federico

• NSKeyedArchiver on NSArray has large size overhead

  - by redguy

  I'm using NSKeyedArchiver in Mac OS X program which generates data for iPhone application. I found out that by default, resulting archives are much bigger than I expected. Example: NSMutableArray * ar = [NSMutableArray arrayWithCapacity:10]; for (int i = 0; i < 100000; i++) { NSString * s = [NSString stringWithFormat:@"item%06d", i]; [ar addObject:s]; } [NSKeyedArchiver archiveRootObject:ar toFile: @"NSKeyedArchiver.test"]; This stores 10 * 100000 = 1M bytes of useful data, yet the size of the resulting file is almost three megabytes. The overhead seems to be growing with number of items in the array. In this case, for 1000 items, the file was about 22k. "file" reports that it is a "Apple binary property list" (not the XML format). Is there an simple way to prevent this huge overhead? I wanted to use the NSKeyedArchiver for the simplicity it provides. I can write data to my own, non-generic, binary format, but that's not very elegant. Also, aggregating the data into large chunks and feeding these to the NSKeyedArchiver should work, but again, that kinda beats the point of using simple&easy&ready to use archiver. Am I missing some method call or usage pattern that would reduce this overhead?

• VPython in Eclipse - thinks it has the wrong architecture type.

  - by Duncan Tait

  Evening, So I've recently installed VPython on my MacBook (OS X, Snow Leopard) - and it works absolutely fine in IDLE and from the command line (interactive mode). However, eclipse has issues. Firstly it couldn't find it (which is a bit of an issue actually with all these 'easy install' python modules - when they don't tell you where they actually install to!) but I searched it out in the depths of Library\Frameworks... and added that to the System PYTHONPATH listbox in Eclipse. Now it can find it, but it says the following: Traceback (most recent call last): File "/Users/duncantait/dev/workspace/Network_Simulation/src/Basic/Net_Sim1.py", line 15, in <module> import visual File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/visual/__init__.py", line 59, in <module> import cvisual ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/visual/cvisual.so, 2): no suitable image found. Did find: /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/visual/cvisual.so: mach-o, but wrong architecture I am guessing that VPython might not be built for a 64-bit architecture (Intel), but the fact remains that it works in both IDLE and command prompt... So there must be a way to configure Eclipse to run it right? (Wishful thinking). Thanks for any help! Duncan

• Running multiple instances of tomcat in eclipse WTP

  - by lisak

  Hey, SCENARIO: 10 CATALINA_BASEs with own configuration (always the same port numbers 8080, but 10 different IP/hostnames on one host via virtual IPs). created a server in WTP and pick "Use the custom location" option in the server configuration in eclipse. New configuration files are created in workspace/Server/server-name-config/ Set up the server path and deploy path for my catalina base (not the internal .metadata one) After I started it, the new configuration files overwrote the original catalina-base/conf files I had there - I was glad, it should be like this but after I made changes in the eclipse config files workspace/Server/server-name-config/ and restarted the server, the changes didn't appeared in the original files in CATALINA_BASE/conf What the hell is that ? So I set the CATALINA_BASE/conf/server.xml to fault configuration and restarted tomcat from eclipse and it worked ! it took the configuration from /Server/server-name-config/server.xml Then I deleted CATALINA_BASE/conf/server.xml and it said that there is no server.xml in catalina base ! How is it possible ? I don't understand why eclipse WTP developers made so tight integration. There should by just symbolic links in /Server/server-name-config/ pointing to CATALINA_BASE/conf/ ... now there is a weird system which is totally unpredictable. The changes in /Server/server-name-config/ are not reflected in CATALINA_BASE/conf ... from where the standard bootstrap.jar or other catalina classloaders and classes build server, engine and other objects with particular setting. Moreover the CATALINA_BASEs could be used outside eclipse then. The second problem, I'm setting up various things in CATALINA_BASE/bin/startup.sh and setenv.sh which is easy cause I can use bash for it. Is then modifying VM parameters in the "Open launch configuration" settings the only way how to do it in eclipse ? Sorry for such a huge pile of questions, but I'm annoyed by the fact that it is much better to not use eclipse WTP for this because it is very poorly designed and it's a shame because this would spare me a lot of time. And using the internal .metadata/ instances it's even more terrifying way that the one I described.

• Detecting Xml namespace fast

  - by Anna Tjsoken

  Hello there, This may be a very trivial problem I'm trying to solve, but I'm sure there's a better way of doing it. So please go easy on me. I have a bunch of XSD files that are internal to our application, we have about 20-30 Xml files that implement datasets based off those XSDs. Some Xml files are small (<100Kb), others are about 3-4Mb with a few being over 10Mb. I need to find a way of working out what namespace these Xml files are in order to provide (something like) intellisense based off the XSD. The implementation of this is not an issue - another developer has written the code for this. But I'm not sure the best (and fastest!) way of detecting the namespace is without the use of XmlDocument (which does a full parse). I'm using C# 3.5 and the documents come through as a Stream (some are remote files). All the files are *.xml (I can detect if it was extension based) but unfortunately the Xml namespace is the only way. Right now I've tried XmlDocument but I've found it to be innefficient and slow as the larger documents are awaiting to be parsed (even the 100Kb docs). public string GetNamespaceForDocument(Stream document); Something like the above is my method signature - overloads include string for "content". Would a RegEx (compiled) pattern be good? How does Visual Studio manage this so efficiently? Another college has told me to find a fast Xml parser in C/C++, parse the content and have a stub that gives back the namespace as its slower in .NET, is this a good idea?

• Embedding two slideshows

  - by Jennifer Heidelberg

  Hello, I am trying to embedd two slideshows into my flash file. I already managed to integrate one, but I can't integrate another since my knowledge of actionscript is very limited. For people that know Flash well it is a really easy question. What do I have to rename in this script so that I can create a second slideshow, without always calling on the first one. Here is the script for the first slideshow: (I got it from the website where I bought the template for the slideshow from) var loader:Loader = new Loader(); var monoslideshow:Object; loader.contentLoaderInfo.addEventListener(Event.CO MPLETE, onLoadComplete); addChild(loader); loader.load(new URLRequest("monoslideshow.swf")); function onLoadComplete(event:Event):void { monoslideshow = event.target.content; monoslideshow.showLogo = false; monoslideshow.setViewport(new Rectangle(730, 20, 700, 660)); var xml:XML = monoslideshow.loadXML(xml); } Thank you very much in advance!!

• Table Design For SystemSettings, Best Model

  - by Chris L

  Someone suggested moving a table full of settings, where each column is a setting name(or type) and the rows are the customers & their respective settings for each setting. ID | IsAdmin | ImagePath ------------------------------ 12 | 1          | \path\to\images 34 | 0          | \path\to\images The downside to this is every time we want a new setting name(or type) we alter the table(via sql) and add the new (column)setting name/type. Then update the rows(so that each customer now has a value for that setting). The new table design proposal. The proposal is to have a column for setting name and another column for setting. ID | SettingName | SettingValue ---------------------------- 12 | IsAdmin        | 1 12 | ImagePath   | \path\to\images 34 | IsAdmin        | 0 34 | ImagePath   | \path\to\images The point they made was that adding a new setting was as easy as a simple insert statement to the row, no added column. But something doesn't feel right about the second design, it looks bad, but I can't come up with any arguments against it. Am I wrong?

• Stock management of assemblies and its sub parts

  - by The Disintegrator

  I have to track the stock of individual parts and kits (assemblies) and can't find a satisfactory way of doing this. Sample bogus and hyper simplified database: Table prod: prodID 1 prodName Flux capacitor prodCost 900 prodPrice 1350 (900*1.5) prodStock 3 - prodID 2 prodName Mr Fusion prodCost 300 prodPrice 600 (300*2) prodStock 2 - prodID 3 prodName Time travel kit prodCost 1650 (1350+300) prodPrice 2145 (1650*1.3) prodStock 2 Table rels relID 1 relSrc 1 (Flux capacitor) relType 4 (is a subpart of) relDst 3 (Time travel kit) - relID 2 relSrc 2 (Mr Fusion) relType 4 (is a subpart of) relDst 3 (Time travel kit) prodPrice: it's calculated based on the cost but not in a linear way. In this example for costs of 500 or less, the markup is a 200%. For costs of 500-1000 the markup is 150%. For costs of 1000+ the markup is 130% That's why the time travel kit is much cheaper than the individual parts prodStock: here is my problem. I can sell kits or the individual parts, So the stock of the kits is virtual. The problem when I buy: Some providers sell me the Time Travel kit as a whole (with one barcode) and some sells me the individual parts (with a different barcode) So when I load the stock I don't know how to impute it. The problem when I sell: If I only sell kits, calculate the stock would be easy: "I have 3 Flux capacitors and 2 Mr Fusions, so I have 2 Time travel kits and a Flux Capacitor" But I can sell Kits or individual parts. So, I have to track the stock of the individual parts and the possible kits at the same time (and I have to compensate for the sell price) Probably this is really simple, but I can't see a simple solution. Resuming: I have to find a way of tracking the stock and the database/program is the one who has to do it (I cant ask the clerk to correct the stock) I'm using php+MySql. But this is more a logical problem than a programing one

• Slow MySQL Query Breaking my back!

  - by Chris n

  so, I have tried everything I can think of, and can't get this query to happen in less than 3 seconds on my local server. I know the problem has to do with the OR referencing both the owner_id and the person_id. if I run one or the other it happens instantly, but together with an or I can't seem to make it work - I looked into rewriting the code, but the way the app was designed it won't be easy. is there a way I can call an equivalent or that won't take so long? here is the sql: SELECT event_types.name as event_type_name,event_types.id as id, count(events.id) as count,sum(events.estimated_duration) as time_sum FROM events,event_types WHERE event_types.id = events.event_type_id AND events.event_type_id != '4' AND ( events.status!='cancelled') AND events.event_type_id != 64 AND ( events.owner_id = 161 OR events.person_id = 161 ) GROUP BY event_types.name ORDER BY event_types.name DESC; Here's the Explain soup, although I'm guessing it's unnecessary cause there is probably a better way to structure that or that is obvious: thanks so much! chris. +----+-------------+-------------+-------+---------------------------------------------------------------------------------------------------------+-------------------------------+---------+-------------------------------------+------+----------------------------------------------+ | id | select_type | table | type | possible_keys | key | key_len | ref | rows | Extra | +----+-------------+-------------+-------+---------------------------------------------------------------------------------------------------------+-------------------------------+-- | 1 | SIMPLE | event_types | range | PRIMARY | PRIMARY | 4 | NULL | 78 | Using where; Using temporary; Using filesort | | 1 | SIMPLE | events | ref | index_events_on_status,index_events_on_event_type_id,index_events_on_person_id,index_events_on_owner_id | index_events_on_event_type_id | 5 | thenumber_production.event_types.id | 907 | Using where | +----+-------------+-------------+-------+---------------------------------------------------------------------------------------------------------+-------------------------------+---------+-------------------------------------+------+----------------------------------------------+

• reconstructing a tree from its preorder and postorder lists.

  - by NomeN

  Consider the situation where you have two lists of nodes of which all you know is that one is a representation of a preorder traversal of some tree and the other a representation of a postorder traversal of the same tree. I believe it is possible to reconstruct the tree exactly from these two lists, and I think I have an algorithm to do it, but have not proven it. As this will be a part of a masters project I need to be absolutely certain that it is possible and correct (Mathematically proven). However it will not be the focus of the project, so I was wondering if there is a source out there (i.e. paper or book) I could quote for the proof. (Maybe in TAOCP? anybody know the section possibly?) In short, I need a proven algorithm in a quotable resource that reconstructs a tree from its pre and post order traversals. Note: The tree in question will probably not be binary, or balanced, or anything that would make it too easy. Note2: Using only the preorder or the postorder list would be even better, but I do not think it is possible. Note3: A node can have any amount of children. Note4: I only care about the order of siblings. Left or right does not matter when there is only one child.

• How to keep track of a private messaging system using MongoDB?

  - by luckytaxi

  Take facebook's private messaging system where you have to keep track of sender and receiver along w/ the message content. If I were using MySQL I would have multiple tables, but with MongoDB I'll try to avoid all that. I'm trying to come up with a "good" schema that can scale and is easy to maintain. If I were using mysql, I would have a separate table to reference the user and and message. See below ... profiles table user_id first_name last_name message table message_id message_body time_stamp user_message_ref table user_id (FK) message_id (FK) is_sender (boolean) With the schema listed above, I can query for any messages that "Bob" may have regardless if he's the recipient or sender. Now how to turn that into a schema that works with MongoDB. I'm thinking I'll have a separate collection to hold the messages. Problem is, how can I differentiate between the sender and the recipient? If Bob logs in, what do I query against? Depending on whether Bob initiated the email, I don't want to have to query against "sender" and "receiver" just to see if the message belongs to the user.

• structured vs. unstructured data in db

  - by Igor

  the question is one of design. i'm gathering a big chunk of performance data with lots of key-value pairs. pretty much everything in /proc/cpuinfo, /proc/meminfo/, /proc/loadavg, plus a bunch of other stuff, from several hundred hosts. right now, i just need to display the latest chunk of data in my UI. i will probably end up doing some analysis of the data gathered to figure out performance problems down the road, but this is a new application so i'm not sure what exactly i'm looking for performance-wise just yet. i could structure the data in the db -- have a column for each key i'm gathering. the table would end up being O(100) columns wide, it would be a pain to put into the db, i would have to add new columns if i start gathering a new stat. but it would be easy to sort/analyze the data just using SQL. or i could just dump my unstructured data blob into the table. maybe three columns -- host id, timestamp, and a serialized version of my array, probably using JSON in a TEXT field. which should I do? am i going to be sorry if i go with the unstructured approach? when doing analysis, should i just convert the fields i'm interested in and create a new, more structured table? what are the trade-offs i'm missing here?

• How reliable is DateTime.Utc in Silverlight applications?

  - by Edward Tanguay

  I have a silverlight application which users will be running in various time zones. The applications load their data from the server at one time, then cache it in IsolatedStorage. When I make changes to the data on the server, I want to be able to change the "last updated time" so that all applications download the newest data the next time they check this date. However, I'm a bit confused as to how to handle the time zone issue since a if the server is in New York and the update time is set to 2010-01-01 17:00:00 and a client in Seattle checks compares it to its local time of 2010-01-01 14:00:00 it won't update and will continue to provide old data for three more hours. My solution is to always post the update time in UTC time, not with the time on the server, then make the Silverlight app check with DateTime.UtcNow. Is this as easy as it sounds or are their issues with this, e.g. that timezones are not set correctly on computers and hence the SilverlightApp does not report the correct UTC time. Can anyone say from experience how likely it is that using DateTime.UtcNow like this for cache refreshing will work in all cases? If DateTime.UtcNow is not reliable, I will just use an incremented "DataVersion" integer but there are other scenarios in which getting time zone sychronization down would make it useful thoroughly understand how to solve this in silverlight apps.

• Google Radar Chart: Not plotting data

  - by Hallik

  Hi. I have different types of data that I have normalized just with base10, so everything is on a 10 point scale. There are two data points, and the legend for them show up fine. All the points around the radar show up fine and so do the labels for them, but I don't see any filled in data. Outside of the labels and axis, the chart is blank. Below is the actual image tag I render, then I split up the variables on each line for easy readability.

• Replacing specific HTML tags using Regex

  - by matthewpe

  Alright, an easy one for you guys. We are using ActiveReport's RichTextBox to display some random bits of HTML code. The HTML tags supported by ActiveReport can be found here : http://www.datadynamics.com/Help/ARNET3/ar3conSupportedHtmlTagsInRichText.html An example of what I want to do is replace any match of <div style="text-align:*</div> by <p style=\"text-align:*</p> in order to use a supported tag for text-alignment. I have found the following regex expression to find the correct match in my html input: <div style=\"text-align:(.*?)</div> However, I can't find a way to keep the previous text contained in the tags after my replacement. Any clue? Is it me or Regex are generally a PITA? :) private static readonly IDictionary<string, string> _replaceMap = new Dictionary<string, string> { {"<div style=\"text-align:(.*?)</div>", "<p style=\"text-align:(.*?)</p>"} }; public static string FormatHtml(string html) { foreach(var pair in _replaceMap) { html = Regex.Replace(html, pair.Key, pair.Value); } return html; } Thanks!

• Remove parent of matched locator

  - by Ilan

  Is there a way to locate a node based child properties? I need to run a web.config transform to remove the 2nd <dependentAssembly in the following: <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <!-- Don't want to delete this one --> <dependentAssembly> <assemblyIdentity name="System.Web.Helpers" publicKeyToken="31bf3856ad364e35"/> <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="2.0.0.0"/> </dependentAssembly> <!-- This is the one I want to delete --> <dependentAssembly> <assemblyIdentity name="Microsoft.VisualStudio.Enterprise.AspNetHelper" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/> <codeBase version="11.0.0.0" href="file:///C:/Program%20Files%20(x86)/Microsoft%20Visual%20Studio%2011.0/Common7/IDE/PrivateAssemblies/Microsoft.VisualStudio.Enterprise.AspNetHelper.DLL"/> </dependentAssembly> </assemblyBinding> </runtime> Finding the <assemblyIdentity is easy enough, but I need to delete the parent <dependentAssembly (and <codeBase). If there was a "xdt:Transform="RemoveParent" this would do the trick, but AFAIK there isn't. Alternatively if there was a Locator I could use on the <dependentAssembly which would match children, then that could work too.

• understanding valgrind output

  - by sbsp

  Hi, i made a post earlier asking about checking for memory leaks etc, i did say i wasnt to familiar with the terminal in linux but someone said to me it was easy with valgrind i have managed to get it running etc but not to sure what the output means. Glancing over, all looks good to me but would like to run it past you experience folk for confirmation if possible. THe output is as follows ^C==2420== ==2420== HEAP SUMMARY: ==2420== in use at exit: 2,240 bytes in 81 blocks ==2420== total heap usage: 82 allocs, 1 frees, 2,592 bytes allocated ==2420== ==2420== LEAK SUMMARY: ==2420== definitely lost: 0 bytes in 0 blocks ==2420== indirectly lost: 0 bytes in 0 blocks ==2420== possibly lost: 0 bytes in 0 blocks ==2420== still reachable: 2,240 bytes in 81 blocks ==2420== suppressed: 0 bytes in 0 blocks ==2420== Reachable blocks (those to which a pointer was found) are not shown. ==2420== To see them, rerun with: --leak-check=full --show-reachable=yes ==2420== ==2420== For counts of detected and suppressed errors, rerun with: -v ==2420== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 13 from 8) Is all good here? the only thing concerning me is the still reachable part. Is that ok? Thanks everyone

• Any good tutorials or resources for learning how to design a scalable and "component" based game 'fr

  - by CodeJustin.com

  In short I'm creating a 2D mmorpg and unlike my last "mmo" I started developing I want to make sure that this one will scale well and work well when I want to add new in-game features or modify existing ones. With my last attempt with an avatar chat within the first few thousand lines of code and just getting basic features added into the game I seen my code quality lowering and my ability to add new features or modify old ones was getting lower too as I added more features in. It turned into one big mess that some how ran, lol. This time I really need to buckle down and find a design that will allow me to create a game framework that will be easy to add and remove features (aka things like playing mini-games within my world or a mail system or buddy list or a new public area with interactive items). I'm thinking that maybe a component based approach MIGHT be what I'm looking for but I'm really not sure. I have read documents on mmorpg design and 2d game engine architecture but nothing really explained a way of designing a game framework that will basically let me "plug-in" new features into the main game and use the resources of the main game without changing much within my 'main game code'. Hope someone understands what I mean, any help will is appreciated.

• Automatically resize jQuery UI dialog to the width of the content loaded by ajax

  - by womp

  I'm having a lot of trouble finding specific information and examples on this. I've got a number of jQuery UI dialogs in my application attached to divs that are loaded with .ajax() calls. They all use the same setup call: $(".mydialog").dialog({ autoOpen: false, resizable: false, modal: true }); I just want to have the dialog resize to the width of the content that gets loaded. Right now, the width just stays at 300px (the default) and I get a horizontal scrollbar. As far as I can tell, "autoResize" is no longer an option for dialogs, and nothing happens when I specify it. I'm trying to not write a separate function for each dialog, so .dialog("option", "width", "500") is not really an option, as each dialog is going to have a different width. Specifying width: 'auto' for the dialog options just makes the dialogs take up 100% of the width of the browser window. What are my options? I'm using jQuery 1.4.1 with jQuery UI 1.8rc1. It seems like this should be something that is really easy. EDIT: I've implemented a kludgy workaround for this, but I'm still looking for a better solution.
