• Trimming bit of the beginning off a recorder waveform

  - by Lowgain

  I've got a flash 10.1 app that lets me record microphone input to a wav without a media server, which I am saving to an Amazon S3 bucket. I have another process running on a server which gets wavs from this bucket, converts to mp3 using LAME and puts them into another bucket. This all works fine, but in converting wav mp3, about 0.1sec or so of silence is added to my sound. In the application this are being used in, perfect sync is critical, so I need to trim off that little bit. If I have to trim it off the original waveform that is okay, I don't expect anything important to happen in that first fraction of a second. What is the best way to go about this? I am using Adobe's WavWriter to convert by ByteArray into a proper waveform. Is there a way I can easily trim off the first few samples from my ByteArray without invalidating the structure? Alternatively, is there a good server-side tool I can use to trim the wav before running it through LAME, or an argument I can give LAME? Or, could I even trim that sound off the mp3 after it has been converted? Thanks!

• Practical refactoring using unit tests

  - by awhite

  Having just read the first four chapters of Refactoring: Improving the Design of Existing Code, I embarked on my first refactoring and almost immediately came to a roadblock. It stems from the requirement that before you begin refactoring, you should put unit tests around the legacy code. That allows you to be sure your refactoring didn't change what the original code did (only how it did it). So my first question is this: how do I unit-test a method in legacy code? How can I put a unit test around a 500 line (if I'm lucky) method that doesn't do just one task? It seems to me that I would have to refactor my legacy code just to make it unit-testable. Does anyone have any experience refactoring using unit tests? And, if so, do you have any practical examples you can share with me? My second question is somewhat hard to explain. Here's an example: I want to refactor a legacy method that populates an object from a database record. Wouldn't I have to write a unit test that compares an object retrieved using the old method, with an object retrieved using my refactored method? Otherwise, how would I know that my refactored method produces the same results as the old method? If that is true, then how long do I leave the old deprecated method in the source code? Do I just whack it after I test a few different records? Or, do I need to keep it around for a while in case I encounter a bug in my refactored code? Lastly, since a couple people have asked...the legacy code was originally written in VB6 and then ported to VB.NET with minimal architecture changes.

• How to flush DNS cache in Windows Mobile programmatically?

  - by Bounded

  Hello, My windows mobile application (written in C# with the compact framework) needs to know if a particular machine is active or not. To achieve this goal, I thought to use a ping mechanism. I tried to use the Ping class implemented in the opennetcf framework (the System.Net.NetworkInformation.Ping class for the .NET Framework is not part of the compact framework). Because I give to the Ping.Send function a host name, it first tries to resolve this host name and to retrieve an IP address. But i observe the following problem : If the first dns resolution fails (because the network is down at this moment), and if the application tries immediately again to send the ping, it fails too, even if the network is note down anymore. I check with a famous network protocol analyzer and i saw that only the requests concerning the first dns resolution are sent. The requests concerning the dns resolution of the second ping are not sent. Why is the second dns request not sent ? Is there any dns cache mechanism on such Windows Mobile devices ? If yes, can this mechanism beeing flushed programmatically ? EDIT : I gave up finding a solution to this DNS flush. I chose to ping an IP adress instead of a name machine. The problem of pinging an hard coded adress IP is that we have to be 100% sure that this IP will not change. The gateway IP can be used because it's always reachable (if it does not, it means the network is down).

• Delphi: how to lock dfm-s to not change...?

  - by durumdara

  Hi! We used Delphi 6 long times ago. Our problem, that Delphi have two problems with DFMs: 1.) When some linked resource (like DataSet) will removed, Delphi many times forget to ask you that "some of the resources are linked, you need to redirect...". This happens, when the actual form is not added to the project, or it is not opened. 2.) When we only open the DFM, and only see some thing, may we change it (active TabSheet, form position). Then Delphi auto save the form - and sometimes it drops the links. Another problem with this that we used SVN, and SVN detect these changes... We thought that we change DFM files to read only, but this can prevent the usage of SVN too... So somebody please help us: have the Delphi some extension (like gexpert) that can lock the DFMs to avoid changes, and some other tool to see that dataset is used in other forms or not? Thanks for your help: dd

• Setting up a domain using WAMP and NameCheap's DNS service

  - by Mike Jones

  So, I've been working on this for far longer than I should be and I'm quite thoroughly perplexed and lost. I apologize if this turns out to be a facile question, but I'm entirely befuddled and very much in need of some guidance. Earlier today I registered a cheap .info domain on NameCheap just to play around with as I learn webdev. I have WAMP installed on my computer and I've been testing my projects through localhost. I thought it would be a good idea to have a domain at my disposal in order to understand how it works and better test my work. NameCheap has a complimentary DNS service (not that I entirely understand what DNS is, although I tried), so I'm using that. I direct both the "@" and "www" host names to my IP address, as shown in the below tutorial: https://www.namecheap.com/support/knowledgebase/article.aspx/319/78/how-can-i-setup-an-a-address-record-for-my-domain However, now when I go to the URL of the domain I bought, it confronts me with a login box that seems to be coming from my wifi network. How do I set this up so that it hosts the information in my WAMP server? Thanks in advance for any help, I really appreciate it. And, as a side-note, what should read (print or online) to better understand the structure of the internet? I've been studying HTML/CSS/Javascript, but I'm not sure where to look for pragmatic and comprehensive information on how the internet works and how to utilize it as a website administrator. Thanks so much.

• Find items with belongs_to associations in Rails?

  - by dannymcc

  Hi Everyone, I have a model called Kase each "Case" is assigned to a contact person via the following code: class Kase < ActiveRecord::Base validates_presence_of :jobno has_many :notes, :order => "created_at DESC" belongs_to :company # foreign key: company_id belongs_to :person # foreign key in join table belongs_to :surveyor, :class_name => "Company", :foreign_key => "appointedsurveyor_id" belongs_to :surveyorperson, :class_name => "Person", :foreign_key => "surveyorperson_id" I was wondering if it is possible to list on the contacts page all of the kases that that person is associated with. I assume I need to use the find command within the Person model? Maybe something like the following? def index @kases = Person.Kase.find(:person_id) or am I completely misunderstanding everything again? Thanks, Danny EDIT: If I use: @kases= @person.kases I can successfully do the following: <% if @person.kases.empty? %> No Cases Found <% end %> <% if @person.kases %> This person has a case assigned to them <% end %> but how do I output the "jobref" field from the kase table for each record found?

• Calculate differences between rows while grouping with SQL

  - by Guido

  I have a postgresql table containing movements of different items (models) between warehouses. For example, the following record means that 5 units of model 1 have been sent form warehouse 1 to 2: source target model units ------ ------ ----- ----- 1 2 1 5 I am trying to build a SQL query to obtain the difference between units sent and received, grouped by models. Again with an example: source target model units ------ ------ ----- ----- 1 2 1 5 -- 5 sent from 1 to 2 1 2 2 1 2 1 1 2 -- 2 sent from 2 to 1 2 1 1 1 -- 1 more sent from 2 to 1 The result should be: source target model diff ------ ------ ----- ---- 1 2 1 2 -- 5 sent minus 3 received 1 2 2 1 I wonder if this is possible with a single SQL query. Here is the table creation script and some data, just in case anyone wants to try it: CREATE TEMP TABLE movements ( source INTEGER, target INTEGER, model INTEGER, units INTEGER ); insert into movements values (1,2,1,5); insert into movements values (1,2,2,1); insert into movements values (2,1,1,2); insert into movements values (2,1,1,1);

• ldap_bind_s returning LDAP_SUCCESS with wrong credentials

  - by rezna

  Hi guys, I have this little problem. I want to authenticate user against LDAP (Windows Active Directory), everything works OK, but the combination (good user, good password, wrong domain). LDAP* ldap = ldap_init(L"myserver", 389); ULONG ldap_version = 3; ULONG ret = LDAP_SUCCESS; ret = ldap_set_option(ldap, LDAP_OPT_PROTOCOL_VERSION, (void*)&ldap_version); ret = ldap_connect(ldap, NULL); SEC_WINNT_AUTH_IDENTITY ai; ai.Domain = (unsigned short*)BAD_DOMAIN; ai.DomainLength = wcslen(BAD_DOMAIN); ai.User = (unsigned short*)OK_USER; ai.UserLength = wcslen(OK_USER); ai.Password = (unsigned short*)OK_PASS; ai.PasswordLength = wcslen(OK_PASS); ai.Flags = SEC_WINNT_AUTH_IDENTITY_UNICODE; ret = ldap_bind_s(ldap, NULL, (PWCHAR) &ai, LDAP_AUTH_NTLM); // !!! HERE !!! ret = ldap_unbind_s(ldap); On the line marke '!!! HERE !!!' I'd expect 0x31 or any other error returned. Instead I get LDAP_SUCCESS :( Any suggestions? Thx, Milan

• Find out which row caused the error

  - by Felipe Fiali

  I have a big fat query that's written dynamically to integrate some data. Basically what it does is query some tables, join some other ones, treat some data, and then insert it into a final table. The problem is that there's too much data, and we can't really trust the sources, because there could be some errored or inconsistent data. For example, I've spent almost an hour looking for an error while developing using a customer's database because somewhere in the middle of my big fat query there was an error converting some varchar to datetime. It turned out to be that they had some sales dating '2009-02-29', an out-of-range date. And yes, I know. Why was that stored as varchar? Well, the source database has 3 columns for dates, 'Month', 'Day' and 'Year'. I have no idea why it's like that, but still, it is. But how the hell would I treat that, if the source is not trustable? I can't HANDLE exceptions, I really need that it comes up to another level with the original message, but I wanted to provide some more info, so that the user could at least try to solve it before calling us. So I thought about displaying to the user the row number, or some ID that would at least give him some idea of what record he'd have to correct. That's also a hard job because there will be times when the integration will run up to 80000 records. And in an 80000 records integration, a single dummy error message: 'The conversion of a varchar data type to a datetime data type resulted in an out-of-range datetime value' means nothing at all. So any idea would be appreciated. Oh I'm using SQL Server 2005 with Service Pack 3.

• Is there a way to trace through only project source in Delphi?

  - by Justin

  I'm using Delphi 2010 and I'm wondering if there's a way to trace through code which is in the project without tracing through calls to included VCLs. For example - you put in a breakpoint and then use Shift+F7 to trace through line-by-line. Now you run into a call to some lengthy procedure in a VCL - in my case it's often a Measurement Studio or other component that draws the doodads for a bunch of I/O, OPC, or other bits. At any rate, what happens is that the debugger hops out of the active source file, opens the component source, and traces through that line by line. Often this is hundreds or thousands of lines of code I don't care about - I just want to have it execute and return to the next source line in MY project. Obviously you can do this by setting breakpoints around every instance of an external call, but often there are too many to make this practical - I'd be spending an hour setting a hundred breakpoints every time I wanted to step through a section of code. Is there a setting or a tool somewhere that can do this? Allow one to trace through code within the project while silently executing code which is external to the project? Thanks in advance, Stack Overflow!

• Is there a way to get number of connections in Signalr hub group?

  - by pajo

  Here is my problem, I want to track if user is online or offline and notify other clients about it. I'm using hubs and implemented both IConnected and IDisconnect interfaces. My idea was to send notification to all clients when hub detects connect or disconnect. By default when user refreshes page he will get new connection id and eventually previous connection will call disconnect notifying other clients user is offline even though he's actually online. I tired to use my own ConnectionIdFactory returning username for connection id but with multiple tabs opened at some point it will detect user connectionid disconnected and after that client side hub will try to unsuccessfully connect to the hub in endless loop wasting memory and cpu making browser almost unusable. I needed to fix it fast so I removed my factory and now I add every new connection to the group using username, so I can easily notify single user on all connections, but then I have problem of detecting if user is online or offline as I don't know how many active connection user is having. So I'm wondering is there a way to get number of connections in one group? Or if anybody has some better idea how to track when user goes offline? I'm using Signalr 0.4

• desing pattern for related inputs

  - by curiousMo

  My question is a design question : let's say i have a data entry web page with 4 drop down lists, each depending on the previous one, and a bunch of text boxes. country (ddl), state (ddl), city (ddl), boro (ddl), address (txtBox), zipcode(txtbox). and an object that represents a datarow with a value for each. naturally the country, state, city and boro values will be values of primary keys of some lookup tables. when the user chooses to edits that record, i would load it from database and load it into the page. the issue that I have is how to streamline loading the ddls. i have some code that would grab the object, look thru its values and move them to their corresponding input controls in one shot. but in this case i will have to load possible values of country, then assign values, then load values of state, then assign value ans so on. I guess i am looking for an elegant solution. i am using asp.net, but i think it is irrelevant to the question. i am looking more into a design pattern. thanks

• Why do System.IO.Log SequenceNumbers have variable length?

  - by Doug McClean

  I'm trying to use the System.IO.Log features to build a recoverable transaction system. I understand it to be implemented on top of the Common Log File System. The usual ARIES approach to write-ahead logging involves persisting log record sequence numbers in places other than the log (for example, in the header of the database page modified by the logged action). Interestingly, the documentation for CLFS says that such sequence numbers are always 64-bit integers. Confusingly, however, the .Net wrapper around those SequenceNumbers can be constructed from a byte[] but not from a UInt64. It's value can also be read as a byte[], but not as a UInt64. Inspecting the implementation of SequenceNumber.GetBytes() reveals that it can in fact return arrays of either 8 or 16 bytes. This raises a few questions: Why do the .Net sequence numbers differ in size from the CLFS sequence numbers? Why are the .Net sequence numbers variable in length? Why would you need 128 bits to represent such a sequence number? It seems like you would truncate the log well before using up a 64-bit address space (16 exbibytes, or around 10^19 bytes, more if you address longer words)? If log sequence numbers are going to be represented as 128 bit integers, why not provide a way to serialize/deserialize them as pairs of UInt64s instead of rather-pointlessly incurring heap allocations for short-lived new byte[]s every time you need to write/read one? Alternatively, why bother making SequenceNumber a value type at all? It seems an odd tradeoff to double the storage overhead of log sequence numbers just so you can have an untruncated log longer than a million terabytes, so I feel like I'm missing something here, or maybe several things. I'd much appreciate it if someone in the know could set me straight.

• Help with MySQL Query using CASE statement

  - by hairdresser-101

  I am trying to group a number of customers together based on their "Head Office" or "Parent" location. THis works ok except for a flaw which I didn't forsee when I was developing my system... For customers that did not have a "Parent" (standalone business) I defaulted the parent_id to 0. Therefore, my data would look like this: id parent_id customer 1 0 CustName#1 2 4 CustName#2 - Melbourne 3 4 CustName#2 - Sydney 4 0 CustName#2 (Head Office) What I want to do is Group my results together so that I have one row for CustName#1 and one row for CustName#2 BUT my problem is that there is no parent record for parent_id=0 and these rows are being excluded when using an inner join. I've tried using a case statement but that is not working either (parents are still being ignored) Any help would be greatly appreciated. Here is my query (My CASE is basically trying to get the business_name from the customer table based on the parent_id EXCEPT when the parent_id = 0, THEN just use the customer_name that is listed in the job_summary table): SELECT js.month_of_year, (CASE js.parent_id WHEN 0 THEN js.customer_name ELSE c.business_name END) as customer, SUM(js.jobs), SUM(js.total_cost), sum(js.total_sell) FROM JOB_SUMMARY js INNER JOIN customer c on js.parent_id=c.id group by js.month_of_year, (CASE c.parent_id WHEN 0 THEN js.customer_name ELSE c.business_name END) ORDER BY `customer` ASC

• Sql query - selecting top 5 rows and further selecting rows only if User is present

  - by Gublooo

  Hello, I kind of stuck on how to implement this query - this is pretty similar to the query I posted earlier but I'm not able to crack it. I have a shopping table where everytime a user buys anything, a record is inserted. Some of the fields are * shopping_id (primary key) * store_id * user_id Now what I need is to pull only the list of those stores where he's among the top 5 visitors: When I break it down - this is what I want to accomplish: * Find all stores where this UserA has visited * For each of these stores - see who the top 5 visitors are. * Select the store only if UserA is among the top 5 visitors. The corresponding queries would be: select store_id from shopping where user_id = xxx select user_id,count(*) as 'visits' from shopping where store_id in (select store_id from shopping where user_id = xxx) group by user_id order by visits desc limit 5 Now I need to check in this resultset if UserA is present and select that store only if he's present. For example if he has visited a store 5 times - but if there are 5 or more people who have visited that store more than 5 times - then that store should not be selected. So I'm kind of lost here. Thanks for your help

• Can any linux API or tool watch for any change in any folder below e.g. /SharedRoot or do I have to

  - by Simon B.

  I have a folder with ~10 000 subfolders. Can any linux API or tool watch for any change in any folder below e.g. /SharedRoot or do I have to setup inotify for each folder? (i.e. I loose if I want to do this for 10k+ folders). I guess yes, since I've already seen examples of this inefficient method, for instance http://twistedmatrix.com/trac/browser/trunk/twisted/internet/inotify.py?rev=28866#L345 My problem: I need to keep folders time-sorted with most recently active "project" up top. When a file changes, each folder above that file should update its last-modified timestamp to match the file. Delays are ok. Opening a file (typically MS Excel) and closing again, its file date can jump up and then down again. For this reason I need to wait until after a file is closed, then queue the folder of that file for checking, and only a while later do I go and look for the newest file in its folder, since the filedate of the triggering file could already be back-dated to its original timestamp by Excel or similar programs. Also in case several files from same folder are used/created, it makes sense to buffer timestamping of that folders' parents to at least get a bunch of updates collapsed into one delayed update. I'm looking for a linux solution. I have some code that can be run on a windows server, most of the queing functionality is here: http://github.com/sesam/FolderdateFollowsFiles/blob/master/FolderdateFollowsFiles/Follower.vb Available API:s The relative of inotify on windows, ReadDirectoryChangesW, can watch a folder and its whole subtree; see bWatchSubtree on http://msdn.microsoft.com/en-us/library/aa365465(VS.85).aspx Samba? Patching samba source is a possibility, but perhaps there are already hooks available? Other possibilities, like client side (various windows versions) and spying on file activities in order to update folders recursively?

• jQuery Accordion: IE animation issues

  - by Nathan Long

  Update I am making this a community wiki, for three reasons: I don't feel like I got a definitive answer, but I have long since stopped needing an answer, because I rolled my own accordion function this question gets tons of views, so clearly lots of people are still interested So if anybody wants to change/clarify this question and make it a definitive guide, be my guest. I'm working on a page using jQuery's accordion UI element. I modeled my HTML on that example, except that inside the <li> elements, I have some unordered lists of links. Like this: $(document).ready(function() { $(".ui-accordion-container").accordion( {active: "a.default", alwaysOpen: true, autoHeight: false} ); }); <ul class="ui-accordion-container"> <li> <!-- Start accordion section --> <a href='#' class="accordion-label">A Group of Links</a> <ul class="linklist"> <li><a href="http://example.com">Example Link</a></li> <li><a href="http://example.com">Example Link</a></li> </ul> <!--and of course there's another group --> Problem: IE Animation stinks Although IE7 animates the documentation's example accordion menu just fine, it has problems with mine. Specifically, one accordion menu on the page moves jerkily and has flashes of content. I know that it's not a CSS issue because the same thing happens if I don't include my CSS files. The other accordion menu on the page opens the first section you click and, after that, won't open any of them. Both of these problems are IE-specific, and both go away if I use the option animated: false. But I'd like to keep the default slide animation, since it helps the user understand what the menu is doing. Is there another way?

• MVVM pattern: ViewModel updates after Model server roundtrip

  - by Pavel Savara

  I have stateless services and anemic domain objects on server side. Model between server and client is POCO DTO. The client should become MVVM. The model could be graph of about 100 instances of 20 different classes. The client editor contains diverse tab-pages all of them live-connected to model/viewmodel. My problem is how to propagate changes after server round-trip nice way. It's quite easy to propagate changes from ViewModel to DTO. For way back it would be possible to throw away old DTO and replace it whole with new one, but it will cause lot of redrawing for lists/DataTemplates. I could gather the server side changes and transmit them to client side. But the names of fields changed would be domain/DTO specific, not ViewModel specific. And the mapping seems nontrivial to me. If I should do it imperative way after round-trip, it would break SOC/modularity of viewModels. I'm thinking about some kind of mapping rule engine, something like automappper or emit mapper. But it solves just very plain use-cases. I don't see how it would map/propagate/convert adding items to list or removal. How to identify instances in collections so it could merge values to existing instances. As well it should propagate validation/error info. Maybe I should implement INotifyPropertyChanged on DTO and try to replay server side events on it ? And then bind ViewModel to it ? Would binding solve the problems with collection merges nice way ? Is EventAgregator from PRISM useful for that ? Is there any event record-replay component ? Is there better client side pattern for architecture with server side logic ?

• Nhibernate join on a table twice

  - by Zuber

  Consider the following Class structure... public class ListViewControl { public int SystemId {get; set;} public List<ControlAction> Actions {get; set;} public List<ControlAction> ListViewActions {get; set;} } public class ControlAction { public string blahBlah {get; set;} } I want to load class ListViewControl eagerly using NHibernate. The mapping using Fluent is as shown below public UIControlMap() { Id(x => x.SystemId); HasMany(x => x.Actions) .KeyColumn("ActionId") .Cascade.AllDeleteOrphan() .AsBag() .Cache.ReadWrite().IncludeAll(); HasMany(x => x.ListViewActions) .KeyColumn("ListViewActionId") .Cascade.AllDeleteOrphan() .AsBag() .Cache.ReadWrite().IncludeAll(); } This is how I am trying to load it eagerly var baseActions = DetachedCriteria.For<ListViewControl>() .CreateCriteria("Actions", JoinType.InnerJoin) .SetFetchMode("BlahBlah", FetchMode.Eager) .SetResultTransformer(new DistinctRootEntityResultTransformer()); var listViewActions = DetachedCriteria.For<ListViewControl>() .CreateCriteria("ListViewActions", JoinType.InnerJoin) .SetFetchMode("BlahBlah", FetchMode.Eager) .SetResultTransformer(new DistinctRootEntityResultTransformer()); var listViews = DetachedCriteria.For<ListViewControl>() .SetFetchMode("Actions", FetchMode.Eager) .SetFetchMode("ListViewActions",FetchMode.Eager) .SetResultTransformer(new DistinctRootEntityResultTransformer()); var result = _session.CreateMultiCriteria() .Add("listViewActions", listViewActions) .Add("baseActions", baseActions) .Add("listViews", listViews) .SetResultTransformer(new DistinctRootEntityResultTransformer()) .GetResult("listViews"); Now, my problem is that the class ListViewControl get the correct records in both Actions and ListViewActions, but there are multiple entries of the same record. The number of records is equal to the number of joins made to the ControlAction table, in this case two. How can I avoid this? If I remove the SetFetchMode from the listViews query, the actions are loaded lazily through a proxy which I don't want.

• Can I use a specific model from within a behavior in CakePHP?

  - by Paul Willy

  I'm trying to write a behavior that will give my models access to a simple workflow engine I've devised. The workflow engine itself works as a CakePHP model, with workflow data stored in the database just as any other model data is stored. Basically what I want to do is have the behavior use the workflow model whenever an action is called on the base model. For example, if the edit() action is executed for Posts, then the Post (with the behavior attached) will trigger the workflow behavior with its own model name, action, and id as arguments (e.g. [Post, edit, 1]). Then the behavior will invoke the functionality of the Workflow model, which has a record for what to do when edit is run on Posts (e.g. send e-mail to users who are subscribed to that post) and will carry that out. My question is, what is the proper way to invoke model/controller methods from within the behavior? The model to be used from within the behavior will always be Workflow, but the behavior should be usable from basically any model (aside from Workflow itself). I know I could run SQL queries directly from the behavior, but of course this is not the Cake way :-) Or, am I going about this in the wrong way? I want to store a certain amount of logic in the database so that it is easily configurable by different users, and not have endless configuration checks within the model/controller logic itself so that workflow steps can be easily added/changed/removed in the future.

• Referencing object's identity before submitting changes in LINQ

  - by Axarydax

  Hi, is there a way of knowing ID of identity column of record inserted via InsertOnSubmit beforehand, e.g. before calling datasource's SubmitChanges? Imagine I'm populating some kind of hierarchy in the database, but I wouldn't want to submit changes on each recursive call of each child node (e.g. if I had Directories table and Files table and am recreating my filesystem structure in the database). I'd like to do it that way, so I create a Directory object, set its name and attributes, then InsertOnSubmit it into DataContext.Directories collection, then reference Directory.ID in its child Files. Currently I need to call InsertOnSubmit to insert the 'directory' into the database and the database mapping fills its ID column. But this creates a lot of transactions and accesses to database and I imagine that if I did this inserting in a batch, the performance would be better. What I'd like to do is to somehow use Directory.ID before commiting changes, create all my File and Directory objects in advance and then do a big submit that puts all stuff into database. I'm also open to solving this problem via a stored procedure, I assume the performance would be even better if all operations would be done directly in the database.

• jQuery How do I move an element inside of another element

  - by TripWired

  Hi I'm using grails navigation plugin and when it generates menus it put the sub navigation underneath the main menu, but i'm making my menu a vertical menu so i don't want the sub menu under the whole menu i want it under the active element. Example: this is how it generate the menu and sub menu <ul class="mainmenu"> <li>item1</li> <li>item2</li> <li>item3</li> </ul> <ul class="submenu"> <li>item1</li> <li>item2</li> <li>item3</li> </ul> What i want is: <ul class="mainmenu"> <li>item1 <ul class="submenu"> <li>item1</li> <li>item2</li> <li>item3</li> </ul> </li> <li>item2</li> <li>item3</li> </ul> Since i don't know of a way to make grails nav plugin do this i guess i'll have to make jquery do it after it's generated. Any ideas?
