• Calculating a Sample Covariance Matrix for Groups with plyr

  - by John A. Ramey

  I'm going to use the sample code from http://gettinggeneticsdone.blogspot.com/2009/11/split-apply-and-combine-in-r-using-plyr.html for this example. So, first, let's copy their example data: mydata=data.frame(X1=rnorm(30), X2=rnorm(30,5,2), SNP1=c(rep("AA",10), rep("Aa",10), rep("aa",10)), SNP2=c(rep("BB",10), rep("Bb",10), rep("bb",10))) I am going to ignore SNP2 in this example and just pretend the values in SNP1 denote group membership. So then, I may want some summary statistics about each group in SNP1: "AA", "Aa", "aa". Then if I want to calculate the means for each variable, it makes sense (modifying their code slightly) to use: > ddply(mydata, c("SNP1"), function(df) data.frame(meanX1=mean(df$X1), meanX2=mean(df$X2))) SNP1 meanX1 meanX2 1 aa 0.05178028 4.812302 2 Aa 0.30586206 4.820739 3 AA -0.26862500 4.856006 But what if I want the sample covariance matrix for each group? Ideally, I would like a 3D array, where the I have the covariance matrix for each group, and the third dimension denotes the corresponding group. I tried a modified version of the previous code and got the following results that have convinced me that I'm doing something wrong. > daply(mydata, c("SNP1"), function(df) cov(cbind(df$X1, df$X2))) , , = 1 SNP1 1 2 aa 1.4961210 -0.9496134 Aa 0.8833190 -0.1640711 AA 0.9942357 -0.9955837 , , = 2 SNP1 1 2 aa -0.9496134 2.881515 Aa -0.1640711 2.466105 AA -0.9955837 4.938320 I was thinking that the dim() of the 3rd dimension would be 3, but instead, it is 2. Really this is a sliced up version of the covariance matrix for each group. If we manually compute the sample covariance matrix for aa, we get: [,1] [,2] [1,] 1.4961210 -0.9496134 [2,] -0.9496134 2.8815146 Using plyr, the following gives me what I want in list() form: > dlply(mydata, c("SNP1"), function(df) cov(cbind(df$X1, df$X2))) $aa [,1] [,2] [1,] 1.4961210 -0.9496134 [2,] -0.9496134 2.8815146 $Aa [,1] [,2] [1,] 0.8833190 -0.1640711 [2,] -0.1640711 2.4661046 $AA [,1] [,2] [1,] 0.9942357 -0.9955837 [2,] -0.9955837 4.9383196 attr(,"split_type") [1] "data.frame" attr(,"split_labels") SNP1 1 aa 2 Aa 3 AA But like I said earlier, I would really like this in a 3D array. Any thoughts on where I went wrong with daply() or suggestions? Of course, I could typecast the list from dlply() to a 3D array, but I'd rather not do this because I will be repeating this process many times in a simulation. As a side note, I found one method (http://www.mail-archive.com/[email protected]/msg86328.html) that provides the sample covariance matrix for each group, but the outputted object is bloated. Thanks in advance.

• Java "compare cannot be resolved to a type" error

  - by King Triumph

  I'm getting a strange error when attempting to use a comparator with a binary search on an array. The error states that "compareArtist cannot be resolved to a type" and is thrown by Eclipse on this code: Comparator<Song> compare = new Song.compareArtist(); I've done some searching and found references to a possible bug with Eclipse, although I have tried the code on a different computer and the error persists. I've also found similar issues regarding the capitalization of the compare method, in this case compareArtist. I've seen examples where the first word in the method name is capitalized, although it was my understanding that method names are traditionally started with a lower case letter. I have experimented with changing the capitalization but nothing has changed. I have also found references to this error if the class doesn't import the correct package. I have imported java.util in both classes in question, which to my knowledge allows the use of the Comparator. I've experimented with writing the compareArtist method within the class that has the binary search call as well as in the "Song" class, which according to my homework assignment is where it should be. I've changed the constructor accordingly and the issue persists. Lastly, I've attempted to override the Comparator compare method by implementing Comparator in the Song class and creating my own method called "compare". This returns the same error. I've only moved to calling the comparator method something different than "compare" after finding several examples that do the same. Here is the relevant code for the class that calls the binary search that uses the comparator. This code also has a local version of the compareArtist method. While it is not being called currently, the code for this method is the same as the in the class Song, where I am trying to call it from. Thanks for any advice and insight. import java.io.*; import java.util.*; public class SearchByArtistPrefix { private Song[] songs; // keep a direct reference to the song array private Song[] searchResults; // holds the results of the search private ArrayList<Song> searchList = new ArrayList<Song>(); // hold results of search while being populated. Converted to searchResults array. public SearchByArtistPrefix(SongCollection sc) { songs = sc.getAllSongs(); } public int compareArtist (Song firstSong, Song secondSong) { return firstSong.getArtist().compareTo(secondSong.getArtist()); } public Song[] search(String artistPrefix) { String artistInput = artistPrefix; int searchLength = artistInput.length(); Song searchSong = new Song(artistInput, "", ""); Comparator<Song> compare = new Song.compareArtist(); int search = Arrays.binarySearch(songs, searchSong, compare);

  Hello guys, I'm using this function on my website to transform user input into acceptable URL: function urlize($url) { $search = array('/[^a-z0-9]/', '/--+/', '/^-+/', '/-+$/' ); $replace = array( '-', '-', '', ''); return preg_replace($search, $replace, utf2ascii($url)); } function utf2ascii($string) { $iso88591 = "\\xE0\\xE1\\xE2\\xE3\\xE4\\xE5\\xE6\\xE7"; $iso88591 .= "\\xE8\\xE9\\xEA\\xEB\\xEC\\xED\\xEE\\xEF"; $iso88591 .= "\\xF0\\xF1\\xF2\\xF3\\xF4\\xF5\\xF6\\xF7"; $iso88591 .= "\\xF8\\xF9\\xFA\\xFB\\xFC\\xFD\\xFE\\xFF"; $ascii = "aaaaaaaceeeeiiiidnooooooouuuuyyy"; return strtr(mb_strtolower(utf8_decode($string), 'ISO-8859-1'),$iso88591,$ascii); } I'm having a problem with it though, with numbers. For some reason when I try: echo urlize("test 23342"); I get "test-eiioe". Why is that and how can I fix it? Thank you very much!

• doctrine behaviors , if i did it like this , would be correct ??

  - by tawfekov

  Hi , I am doing a web application in ZF + Doctrine 1.2.3 but i had an old database , it had pretty good structure so i think i can reverse engineer it with doctrine commad ./dcotrine generate-models-db , its amazing but i stopped when i wanted to use some doctrine behaviors like : searchable as an example , my question : if i went to my model and added these two lines : $this->actAs('Searchable', array( 'fields' => array('title', 'content') ) ); i am not sure if that enough and would work as expected , if you had any more tips about creating other behaviors like (versionable , i18n , sluggable or soft delete ) manually or reverse engineer it with doctrine behaviors , could you please list them

• How should I change my Graph structure (very slow insertion)?

  - by Nazgulled

  Hi, This program I'm doing is about a social network, which means there are users and their profiles. The profiles structure is UserProfile. Now, there are various possible Graph implementations and I don't think I'm using the best one. I have a Graph structure and inside, there's a pointer to a linked list of type Vertex. Each Vertex element has a value, a pointer to the next Vertex and a pointer to a linked list of type Edge. Each Edge element has a value (so I can define weights and whatever it's needed), a pointer to the next Edge and a pointer to the Vertex owner. I have a 2 sample files with data to process (in CSV style) and insert into the Graph. The first one is the user data (one user per line); the second one is the user relations (for the graph). The first file is quickly inserted into the graph cause I always insert at the head and there's like ~18000 users. The second file takes ages but I still insert the edges at the head. The file has about ~520000 lines of user relations and takes between 13-15mins to insert into the Graph. I made a quick test and reading the data is pretty quickly, instantaneously really. The problem is in the insertion. This problem exists because I have a Graph implemented with linked lists for the vertices. Every time I need to insert a relation, I need to lookup for 2 vertices, so I can link them together. This is the problem... Doing this for ~520000 relations, takes a while. How should I solve this? Solution 1) Some people recommended me to implement the Graph (the vertices part) as an array instead of a linked list. This way I have direct access to every vertex and the insertion is probably going to drop considerably. But, I don't like the idea of allocating an array with [18000] elements. How practically is this? My sample data has ~18000, but what if I need much less or much more? The linked list approach has that flexibility, I can have whatever size I want as long as there's memory for it. But the array doesn't, how am I going to handle such situation? What are your suggestions? Using linked lists is good for space complexity but bad for time complexity. And using an array is good for time complexity but bad for space complexity. Any thoughts about this solution? Solution 2) This project also demands that I have some sort of data structures that allows quick lookup based on a name index and an ID index. For this I decided to use Hash Tables. My tables are implemented with separate chaining as collision resolution and when a load factor of 0.70 is reach, I normally recreate the table. I base the next table size on this http://planetmath.org/encyclopedia/GoodHashTablePrimes.html. Currently, both Hash Tables hold a pointer to the UserProfile instead of duplication the user profile itself. That would be stupid, changing data would require 3 changes and it's really dumb to do it that way. So I just save the pointer to the UserProfile. The same user profile pointer is also saved as value in each Graph Vertex. So, I have 3 data structures, one Graph and two Hash Tables and every single one of them point to the same exact UserProfile. The Graph structure will serve the purpose of finding the shortest path and stuff like that while the Hash Tables serve as quick index by name and ID. What I'm thinking to solve my Graph problem is to, instead of having the Hash Tables value point to the UserProfile, I point it to the corresponding Vertex. It's still a pointer, no more and no less space is used, I just change what I point to. Like this, I can easily and quickly lookup for each Vertex I need and link them together. This will insert the ~520000 relations pretty quickly. I thought of this solution because I already have the Hash Tables and I need to have them, then, why not take advantage of them for indexing the Graph vertices instead of the user profile? It's basically the same thing, I can still access the UserProfile pretty quickly, just go to the Vertex and then to the UserProfile. But, do you see any cons on this second solution against the first one? Or only pros that overpower the pros and cons on the first solution? Other Solution) If you have any other solution, I'm all ears. But please explain the pros and cons of that solution over the previous 2. I really don't have much time to be wasting with this right now, I need to move on with this project, so, if I'm doing to do such a change, I need to understand exactly what to change and if that's really the way to go. Hopefully no one fell asleep reading this and closed the browser, sorry for the big testament. But I really need to decide what to do about this and I really need to make a change. P.S: When answering my proposed solutions, please enumerate them as I did so I know exactly what are you talking about and don't confuse my self more than I already am.

• get length of data sent over network to TCPlistener/networkstream vb.net

  - by Jonathan.

  It seems the most obvious thing, but I just can't work out how to get the length of bytes sent over a network using a TCPClient and TCPListener? This is my code so far: 'Must listen on correct port- must be same as port client wants to connect on. Const portNumber As Integer = 9999 Dim tcpListener As New TcpListener(IPAddress.Parse("192.168.2.7"), portNumber) tcpListener.Start() Console.WriteLine("Waiting for connection...") 'Accept the pending client connection and return 'a TcpClient initialized for communication. Dim tcpClient As TcpClient = tcpListener.AcceptTcpClient() Console.WriteLine("Connection accepted.") ' Get the stream Dim networkStream As NetworkStream = tcpClient.GetStream() '' Read the stream into a byte array I need to get the length of the networkstream to set the size of the array of bytes I'm going to read the data into. But the networkStream.length is unsupported and does not work and throws an Notsupportedexception. The only other way I can think of is to send the size of the data before sending the data, but this seems the long way round.

• Checking if a touch is withing a UIButton's bounds.

  - by Joshua

  I am trying to make an if statement which will check whether the users touch is within a UIButton's bounds. I thought this would be an easy affair as UIButton is a subclass of UIView, however my code doesn't seem to work. This is the code I have been using. - (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { NSArray *array = [touches allObjects]; UITouch *specificTouch = [array objectAtIndex:0]; currentTouch = [specificTouch locationInView:self.view]; if (CGRectContainsPoint(but.bounds, currentTouch)) { //Do something is in bounds. } //Else do nothing. }

• Sorting/Paginating/Filtering Complex Multi-AR Object Tables in Rails

  - by Matt Rogish

  I have a complex table pulled from a multi-ActiveRecord object array. This listing is a combined display of all of a particular user's "favorite" items (songs, messages, blog postings, whatever). Each of these items is a full-fledged AR object. My goal is to present the user with a simplified search, sort, and pagination interface. The user need not know that the Song has a singer, and that the Message has an author -- to the end user both entries in the table will be displayed as "User". Thus, the search box will simply be a dropdown list asking them which to search on (User name, created at, etc.). Internally, I would need to convert that to the appropriate object search, combine the results, and display. I can, separately, do pagination (mislav will_paginate), sorting, and filtering, but together I'm having some problems combining them. For example, if I paginate the combined list of items, the pagination plugin handles it just fine. It is not efficient since the pagination is happening in the app vs. the DB, but let's assume the intended use-case would indicate the vast majority of the users will have less than 30 favorited items and all other behavior, server capabilities, etc. indicates this will not be a bottleneck. However, if I wish to sort the list I cannot sort it via the pagination plugin because it relies on the assumption that the result set is derived from a single SQL query, and also that the field name is consistent throughout. Thus, I must sort the merged array via ruby, e.g. @items.sort_by{ |i| i.whatever } But, since the items do not share common names, I must first interrogate the object and then call the correct sort by. For example, if the user wishes to sort by user name, if the sorted object is a message, I sort by author but if the object is a song, I sort by singer. This is all very gross and feels quite un-ruby-like. This same problem comes into play with the filter. If the user filters on the "parent item" (the message's thread, the song's album), I must translate that to the appropriate collection object method. Also gross. This is not the exact set-up but is close enough. Note that this is a legacy app so changing it is quite difficult, although not impossible. Also, yes there is some DRY that can be done, but don't focus on the style or elegance of the following code. Style/elegance of the SOLUTION is important, however! :D models: class User < ActiveRecord::Base ... has_and_belongs_to_many :favorite_messages, :class_name => "Message" has_and_belongs_to_many :favorite_songs, :class_name => "Song" has_many :authored_messages, :class_name => "Message" has_many :sung_songs, :class_name => "Song" end class Message < ActiveRecord::Base has_and_belongs_to_many :favorite_messages belongs_to :author, :class_name => "User" belongs_to :thread end class Song < ActiveRecord::Base has_and_belongs_to_many :favorite_songs belongs_to :singer, :class_name => "User" belongs_to :album end controller: def show u = User.find 123 @items = Array.new @items << u.favorite_messages @items << u.favorite_songs # etc. etc. @items.flatten! @items = @items.sort_by{ |i| i.created_at } @items = @items.paginate :page => params[:page], :per_page => 20 end def search # Assume user is searching for username like 'Bob' u = User.find 123 @items = Array.new @items << u.favorite_messages.find( :all, :conditions => "LOWER( author ) LIKE LOWER('%bob%')" ) @items << u.favorite_songs.find( :all, :conditions => "LOWER( singer ) LIKE ... " ) # etc. etc. @items.flatten! @items = @items.sort_by{ |i| determine appropriate sorting based on user selection } @items = @items.paginate :page => params[:page], :per_page => 20 end view: #index.html.erb ... <table> <tr> <th>Title (sort ASC/DESC links)</th> <th>Created By (sort ASC/DESC links))</th> <th>Collection Title (sort ASC/DESC links)</th> <th>Created At (sort ASC/DESC links)</th> </tr> <% @items.each |item| do %> <%= render { :partial => "message", :locals => item } if item.is_a?

• TableView - iVar reset when returning from details view

  - by iFloh

  Hi, anyone knows what I need to do to retain my TableView iVars whilst pushing a details view onto the navigation stack? I have an array and a date defined as iVars and the array is retained, whilst the date is not. I checked whether there may be an autorelease hidden somewhere but there are no obvious ones. The properties are defined as nonatomic, retain. I use custom NSDate category methods to determine specific dates at stages. These use NSDateComponents, NSRange and NSCalendar, for example: - (NSDate *)lastDayOfMonth: { NSCalendar *tmpCal = [NSCalendar currentCalendar]; NSDateComponents *tmpDateComponents = [tmpCal components:NSYearCalendarUnit | NSMonthCalendarUnit | NSEraCalendarUnit | NSWeekCalendarUnit | NSWeekdayOrdinalCalendarUnit fromDate:self]; NSRange tmpRange = [tmpCal rangeOfUnit:NSDayCalendarUnit inUnit:NSMonthCalendarUnit forDate:[tmpCal dateFromComponents:tmpDateComponents]]; [tmpDateComponents setDay:tmpRange.length]; [tmpDateComponents setHour:23]; [tmpDateComponents setMinute:59]; [tmpDateComponents setSecond:59]; return [[NSCalendar currentCalendar] dateFromComponents:tmpDateComponents]; } could they somehow be the reason?

• How to transform a vector<int> into a string?

  - by Legend

  I am trying to pass a value from C++ to TCL. As I cannot pass pointers without the use of some complicated modules, I was thinking of converting a vector to a char array and then passing this as a null terminated string (which is relatively easy). I have a vector as follows: 12, 32, 42, 84 which I want to convert into something like: "12 32 42 48" The approach I am thinking of is to use an iterator to iterate through the vector and then convert each integer into its string representation and then add it into a char array (which is dynamically created initially by passing the size of the vector). Is this the right way or is there a function that already does this?

• Line breaks in "NSString"s returned from PList don't work.

  - by Moshe

  I've seen this post: http://stackoverflow.com/questions/2035567/nsstring-newline-escape-in-plist but I'd like to know if there's a way to pragmatically render \n line breaks. I'm currently using: decisionText.text = [NSString stringWithFormat: (@"%@", [replies objectAtIndex:(arc4random() % [replies count])])]; Which randomly grabs a String from the replies array. The array was loaded from a plist like so: replies = [[NSMutableArray alloc] initWithContentsOfFile:[[NSBundle mainBundle]pathForResource:@"AdviceList" ofType:@"plist"]]; What am I missing? The answer can't be to manually enter line breaks. That's not programming! (Sounds like word processing to me.)

• How to make multiple queries with PHP prepared statements (Commands out of sync error)

  - by Tirithen

  I'm trying to run three MySQL queries from a PHP script, the first one works fine, but on the second one I get the "Commands out of sync; you can’t run this command now" error. I have managed to understand that I need to "empty" the resultset before preparing a new query but I can't seem to understand how. I thought that $statement-close; would do that for me. Here is the relevant part of the code: <?php $statement = $db_conn->prepare("CALL getSketches(?,?)"); // Prepare SQL routine to check if user is accepted $statement->bind_param("is", $user_id, $loaded_sketches); // Bind variables to send $statement->execute(); // Execute the query $statement->bind_result( // Set return varables $id, $name, $description, $visibility, $createdby_id, $createdby_name, $createdon, $permission ); $new_sketches_id = array(); while($statement->fetch()) { $result['newSketches'][$id] = array( "name" => $name, "description" => $description, "visibility" => $visibility, "createdById" => $createdby_id, "createdByName" => $createdby_name, "createdOn" => $createdon, "permission" => $permission ); $new_sketches_id[] = $id; } $statement->close; // Close satement $new_sketches_ids = implode(",", $new_sketches_id); // Get the new sketches elements $statement = $db_conn->prepare("CALL getElements(?,'',?,'00000000000000')"); // Prepare SQL routine to check if user is accepted // The script crashes here with $db_conn->error // "Commands out of sync; you can't run this command now" $statement->bind_param("si", $new_sketches_ids, $user_id); // Bind variables to send $statement->execute(); // Execute the query $statement->bind_result( // Set return varables $id, $user_id, $type, $attribute_d, $attribute_stroke, $attribute_strokeWidth, $sketch_id, $createdon ); while($statement->fetch()) { $result['newSketches'][$sketch_id]['newElements']["u".$user_id."e".$id] = array( "type" => $type, "d" => $attribute_d, "stroke" => $attribute_stroke, "strokeWidth" => $attribute_strokeWidth, ); } $statement->close; // Close satement ?> How can I make the second query without closing and reopening the entire database connection?

• Sugar CRM integration with Java - How to add relationship

  - by Arun P Johny

  Hi, I'm trying to integrate Sugar CRM with one of my projects. I'm using Apache Axis as my SOAP client. I've created the Sugar CRM client Stub classes using Apache Axis. I'm able to login and add Leads, Opportunities, Accounts and Contacts. But I'm unable to add a relation ship between my Account and Opportunity. I've found following method in the SugarsoapPortType port.set_relationship(session, module_name, module_id, link_field_name, related_ids, name_value_list, delete) but I cannot understand the different parameters required by this method. Most of the online documents suggests a simple way as given below $result = $client->call('set_relationship',array("session"=>$session _id,array("module1"=>"Emails","module1_id"=>"<module1_id>","module2"=>"Accounts","module2_id"=> "<module2_id>"))); how can I achieve this using Java Thanks

Who can make this code shorter? private function replaceFunc($subject) { foreach($this->func as $t) { preg_match_all('/\{'.$t.'\([a-zA-Z,\']+\)\}/i', $subject, $res); for($j = 0; $j < sizeof($res[0]); $j++) { preg_match('/\([a-zA-Z,\']+\)/i', $res[0][$j], $match); if($match > 0) { $prep = explode(", ", substr($match[0], 1, -1)); $args = array(); for($i = 0; $i < sizeof($prep); $i++) { $args[] = substr($prep[$i], 1, -1); } } else { $args = array(); } $subject = preg_replace('/\{'.$t.preg_quote($match[0]).'\}/i', call_user_func_array($t, $args), $subject); } } return $subject; }

• Lazy Tables app from iphone

  - by Warrior

  I am new to iphone development. I have parsed a youtube file and displaying its contents with the image in the table view. But the scrolling has become slower because of displaying image.So i want to display the image as the lazy tables program from apple docs.Since they have used navigation based application , their rootviewcontroller loads first and then the delegate class call the parsing ,and when they reload the table view, the contents are displayed. The data array count shows 25. I am using a view controller to display the tables on the present modal view, more over when i run my application, first delegate methods call the parsing. So when i click the youtube icon in my landing page it navigates to table view. So by this time data array count shows 0. I have created table view in interface builder and set the outlets to the file owner properly. Please help me out. I want to increasing the scrolling performance. Thanks.

• Compare values for audit trail

  - by kagaku

  I'm attempting to develop an audit trail/tracking solution for an existing database written in PLSQL/PHP - however I'm still unsure as of yet on an easy (to implement and maintain) solution for tracking changes to fields/values. For instance, the project tracking portion of the DB APP tracks over 200 fields and ideally I'd like a nice way to show a history of changes, such as: 5/10/2010 - Project 435232 updated by John Doe Changed Project Name (Old: Test Project; New: Super Test Project) Changed Submission Date (Old: 5/10/2010; New: 5/11/2010) Changed Description (Old: This is an example!; New: This is a test example) Essentially for each field (db column) it would output a new line to show the old/new values. So far my current idea is saving the current version of the data to a temporary table, updating the primary table with the new data then loading each row into an array and doing an array compare to determine the differences. This seems a bit convoluted, and if there is an easier method I'd love to know it. Any ideas or suggestions are much appreciated!

• Creating a list of integers in XML for android.

  - by Leif Andersen

  I would like to create a list of Integers in the /res folder of an android project. However, I want those integers to point resources in /res/raw. So for example, I would like something like this: <?xml version="1.0" encoding="utf-8"?> <resources> <integer-array name="built_in_sounds"> <item>@raw/sound</item> </integer-array> </resources> But id doesn't look like I can do that, is there any way to do this? Or should I just create the list in a java class? Thank you

• Powershell - Splitting variable into chunks

  - by Andrew

  I have written a query in Powershell interrogating a F5 BIG-IP box through it's iControl API to bring back CPU usage etc. Using this code (see below) I can return the data back into a CSV format which is fine. However the $csvdata variable contains all the data. I need to be able to take this variable and for each line split each column of data into a seperate variable. The output currently looks like this: timestamp,"Utilization" 1276181160,2.3282800000e+00 Any advice would be most welcome $SystemStats = (Get-F5.iControl).SystemStatistics ### Allocate a new Query Object and add the inputs needed $Query = New-Object -TypeName iControl.SystemStatisticsPerformanceStatisticQuery $Query.object_name = $i $Query.start_time = $startTime $Query.end_time = 0 $Query.interval = $interval $Query.maximum_rows = 0 ### Make method call passing in an array of size one with the specified query $ReportData = $SystemStats.get_performance_graph_csv_statistics( (,$Query) ) ### Allocate a new encoder and turn the byte array into a string $ASCII = New-Object -TypeName System.Text.ASCIIEncoding $csvdata = $ASCII.GetString($ReportData[0].statistic_data)

• How to include simple collections in ConfigurationSection

  - by mikemanne

  Is there a way for me to include a simple array of strings, or List<string> on my custom subclass of ConfigurationSection? (Or an array or generic list of simple data objects, for that matter?) I'm becoming familiar with the new (and VERY verbose) ConfigurationSection, ConfigurationElement, and ConfigurationElementCollection classes, but I'm by no means an expert yet. It seems like ConfigurationSection should handle simple collections/lists on its own, without me having to create a custom ConfigurationElementCollection subclass for each and every one. But I haven't found any reference to this ability online.
