• N-son tabbed/JsScrollbar, trying to force gif play from click of link using jquery

  - by user314286

  Hello everyone, Let me start off by stating the obvious; I am new here. That said I hope I am not violating some standard I missed by posting this. xD For several days now I've been trying to update a rather old site of mine, to which I wont link to given that the update is so drastic that the current product on which I seek your help for doesn't resemble the old site in any other way then appearance. Anywho! I am using the tabbed div and JsScrollbar created by N-son (http://www.downloadjavascripts.com/list/javasitek60/Details.aspx) and so far have only used jquery to dynamically center content on the page. My problem however is this...I have a gif on the page that acts as a background (it's not tiled) and I'd like to be able to have it so that when you click on one of the links used in n-sons tabs (EX: news) it also causes the gif to load and play through itself once. So far all my attempts at accomplishing this myself have failed and break wither the scrollbar or prevent the content from switching when you click the tabs. (Except for one failed attempt where it all worked fine except the handle for the scrollbar would vanish upon switching tabs) I hope I've been clear in this and that someone is able to help. I know it may seem like a silly question but we're all new at some point. :P If need be I'll upload what coding I have but it is not pretty. Thank you in advance.

• How to handle activity life cycle involving sockets in Android?

  - by Henrik

  Hello all, I have an Android activity which in turn starts a thread. In the thread I open a persistent TCP socket connection. When the socket connects to the server dynamic data is downloaded. The thread sends messages using Handler-class to the activity when data has been received. Now if the user happens to switch from portrait to landscape mode the activity gets an onDestroy call. At this moment I close the socket and stop the thread. When Android has switched landscape mode it calls onCreate yet again and I have to do a socket re-connect. Also, all of the data the activity received needs to be downloaded once more because the server does not have the ability to know what has been sent before, i.e. there is no "resume" feature. Thus the problem is that there is alot of data which is resent all the time when landscape mode is changed. What are my options here? Should I create a service which handles the socket traffic towards the server thus I always got all the data which the server has sent in the service. Or should I disable landscape mode all together perhaps? Or would my best bet be to rewrite my server which is a VERY BIG job :-) All input is welcome :-) / Henrik

• Data mining - parsing a log file in Java

  - by nuvio

  Hello I am carrying on a Java project for the university, where I should analyse poker hands. I found some poker hands in a txt log file. They would typically look like this: PokerStars Zoom Hand #86981279921: Hold'em No Limit ($0.10/$0.25 USD) - 2012/09/30 23:49:51 ET Table 'Whirlpool Zoom 40-100 bb' 9-max Seat #1 is the button Seat 1: lgwong ($30.99 in chips) Seat 2: hastyboots ($28.61 in chips) Seat 3: seula i ($25.31 in chips) Seat 4: fr_kevin01 ($31.81 in chips) Seat 5: limey05 ($27.45 in chips) Seat 6: sanlu ($24.65 in chips) Seat 7: Masterfrank ($25.35 in chips) Seat 8: Refu$e2Lose ($33.23 in chips) Seat 9: 1pepepe0114 ($37.62 in chips) hastyboots: posts small blind $0.10 seula i: posts big blind $0.25 *** HOLE CARDS *** fr_kevin01: folds limey05: folds sanlu: folds Masterfrank: folds Refu$e2Lose: folds 1pepepe0114: folds lgwong: folds hastyboots: folds Uncalled bet ($0.15) returned to seula i seula i collected $0.20 from pot seula i: doesn't show hand *** SUMMARY *** Total pot $0.20 | Rake $0 Seat 1: lgwong (button) folded before Flop (didn't bet) Seat 2: hastyboots (small blind) folded before Flop Seat 3: seula i (big blind) collected ($0.20) Seat 4: fr_kevin01 folded before Flop (didn't bet) Seat 5: limey05 folded before Flop (didn't bet) Seat 6: sanlu folded before Flop (didn't bet) Seat 7: Masterfrank folded before Flop (didn't bet) Seat 8: Refu$e2Lose folded before Flop (didn't bet) Seat 9: 1pepepe0114 folded before Flop (didn't bet) My problem is that I am not sure about how to proceed to parse the log file: the only knowledge I have is "manually" scanning line by line for a particular character or symbol, but I am afraid it would need exhaustive error handling. So I was wandering if there is any other techniques or better way to parse these poker hands? Many thanks for your help

• Custom Jquery slideshow doesn't want to reset?

  - by Jared

  Hello, Under $(document).ready(function(), I have the following code: num = $("#mainContentCategoryLinksWrapper > div").size(); This makes num equal the length of the children of #mainContentCategoryLinksWrapper. Currently, this equals 4. Above the $(document).ready(function( I have this: var timesRun = 0; function slideshow(){ if(timesRun < num){ $(".arrowIn").stop().animate({color: "#a12324", textIndent: "30px", backgroundPosition: '0px 0px'}, 100, function(){ //the first child in the series has a class of "arrowIn" $(".arrowIn").next().addClass("replaceMe"); //Adds the ".replaceMe" placeholder the the next element. $(".arrowIn").removeClass("arrowIn"); //Deletes the class on the current element $(".replaceMe").addClass("arrowIn").removeClass("replaceMe"); //reassigns ".arrowIn" over ".replaceMe" timesRun = timesRun + 1; //increases number of times run }).prev().animate({color: "#000000", textIndent: "25px", backgroundPosition: '0px -25px'}, {duration: 50}); //puts the previous element back to it's original position }else{ timesRun = 0; $(".arrowIn").removeClass("arrowIn"); $("#mainContentCategoryLinksWrapper:first-child").addClass("arrowIn"); //this is supposed to reset timesRun, and set the first child in the series back to the original ".arrowIn" } } setInterval( 'slideshow()', 1000 ); So here is the what the code does: 1) Animates the first in the series of 4 (#1) timesRun = 1 2) Animates the second in the series of 4 (#2) timesRun = 2 3) Animates the third in the series of 4 (#3) timesRun = 3 4) Animates the fourth in the series of 4 (#4) timesRun = 4 5) timesRun is now longer less than num. Reset class names back to original to .arrowIn, set timesRun to 0. However, when the slideshow() is reexectuted, it doesn't start over. Any ideas? See www.raceramps.com/v3 for an example.

• VB.net httpwebrequest For loop hangs every 10 or so iterations

  - by user574632

  Hello, I am trying to loop through an array and perform an httpwebrequest in each iteration. The code seems to work, however it pauses for a while (eg alot longer than the set timeout. Tried setting that to 100 to check and it still pauses) after every 10 or so iterations, then carries on working. Here is what i have so far: For i As Integer = 0 To numberOfProxies - 1 Try 'create request to a proxyJudge php page using proxy Dim request As HttpWebRequest = HttpWebRequest.Create("http://www.pr0.net/deny/azenv.php") request.Proxy = New Net.WebProxy(proxies(i)) 'select the current proxie from the proxies array request.Timeout = 10000 'set timeout Dim response As HttpWebResponse = request.GetResponse() Dim sr As StreamReader = New StreamReader(response.GetResponseStream()) Dim pageSourceCode As String = sr.ReadToEnd() 'check the downloaded source for certain phrases, each identifies a type of proxy 'HTTP_X_FORWARDED_FOR identifies a transparent proxy If pageSourceCode.Contains("HTTP_X_FORWARDED_FOR") Then 'delegate method for cross thread safe UpdateListbox(ListBox3, proxies(i)) ElseIf pageSourceCode.Contains("HTTP_VIA") Then UpdateListbox(ListBox2, proxies(i)) Else UpdateListbox(ListBox1, proxies(i)) End If Catch ex As Exception 'MessageBox.Show(ex.ToString) used in testing UpdateListbox(ListBox4, proxies(i)) End Try completedProxyCheck += 1 lblTotalProxiesChecked.CustomInvoke(Sub(l) l.Text = completedProxyCheck) Next I have searched all over this site and via google, and most responses to this type of question say the response must be closed. I have tried a using block, eg: Using response As HttpWebResponse = request.GetResponse() Using sr As StreamReader = New StreamReader(response.GetResponseStream()) Dim pageSourceCode As String = sr.ReadToEnd() 'check the downloaded source for certain phrases, each identifies a type of proxy 'HTTP_X_FORWARDED_FOR identifies a transparent proxy If pageSourceCode.Contains("HTTP_X_FORWARDED_FOR") Then 'delegate method for cross thread safe UpdateListbox(ListBox3, proxies(i)) ElseIf pageSourceCode.Contains("HTTP_VIA") Then UpdateListbox(ListBox2, proxies(i)) Else UpdateListbox(ListBox1, proxies(i)) End If End Using End Using And it makes no difference (though i may have implemented it wrong) As you can tell im very new to VB or any OOP so its probably a simple problem but i cant work it out. Any suggestions or just tips on how to diagnose these types of problems would be really appreciated.

• Getting a variable into another class through properties or button tags with Iphone SDK?

  - by MarcZero

  Hello. I have been pounding my head against a wall trying to figure out what I think is a simple thing to do, but I have, so far, been unable to figure it out with the iPhone SDK. I have a view with 4 buttons. When I push the buttons, I have another view called and come up to take over the screen. I want to have a simple variable passed from the old view to the new view. The purpose of this is to know what button was pressed out of the four identical ones. (trying to get an int value of 1 through 4) Here is what I have tried so far: I initially tried to call the variable from the class itself. My understanding was that my new view was only sitting on top of the old view, so it should not have been released. I could not get access to the variable as the variable was said to not be declared. I then tried to create a method that would return the int value. Again, the view class was not seen and was being declared as a "first use" of it. I then attempted to follow another similar post on here that suggested to try and send the button tag number to some part of the new view. I attempted to do this by setting the new views button title but I still cannot figure out a way to code it without coming up with errors. I am just looking for what method would be the best for me to pursue. I have no problem going back and reading the books on Objective-C, but I'm just trying to figure out which way I should concentrate on. Thank you for any insight.

• Sending items in a LINQ sequence to a method that returns void

  - by generalt

  Hello all. Often while I'm dealing with LINQ sequences, I want to send each item to a method returning void, avoiding a foreach loop. However, I haven't found an elegant way to do this. Today, I wrote the following code: private StreamWriter _sw; private void streamToFile(List<ErrorEntry> errors) { if (_sw == null) { _sw = new StreamWriter(Path.Combine (Path.GetDirectoryName(_targetDatabasePath), "errors.txt")); } Func<ErrorEntry, bool> writeSelector = (e) => { _sw.WriteLine(getTabDelimititedLine(e)); return true; }; errors.Select(writeSelector); _sw.Flush(); } As you can see, I write a lambda function that just returns true, and I realize that the Select method will return a sequence of booleans- I'll just ignore that sequence. However, this seems a little bit noobish and jank. Is there any elegant way to do this? Or am I just misapplying LINQ? Thanks.

• Nested namespaces, correct static library design issues

  - by PeterK

  Hello all, I'm currently in the process of developing a fairly large static library which will be used by some tools when it's finished. Now since this project is somewhat larger than anything i've been involved in so far, I realized its time to think of a good structure for the project. Using namespaces is one of those logical steps. My current approach is to divide the library into parts (which are not standalone, but their purpose calls for such a separation). I have a 'core' part which now just holds some very common typedefs and constants (used by many different parts of the library). Other parts are for example some 'utils' (hash etc.), file i/o and so on. Each of these parts has its own namespace. I have nearly finished the 'utils' part and realized that my approach probably is not the best. The problem (if we want to call it so) is that in the 'utils' namespace i need something from the 'core' namespace which results in including the core header files and many using directives. So i began to think that this probably is not a good thing and should be changed somehow. My first idea is to use nested namespaces as to have something like core::utils. Since this will require some heavy refactoring i want to ask here first. What do you think? How would you handle this? Or more generally: How to correctly design a static library in terms of namespaces and code organization? If there are some guidelines or articles about it, please mentoin them too. Thanks. Note: i'm quite sure that there are more good approaches than just one. Feel free to post your ideas, suggestions etc. Since i'm designing this library i want it to be really good. The goal is to make it as clean and FAST as possible. The only problem is that i will have to integrate a LOT of existing code and refactor it, which will really be a painful process (sigh) - thats why good structure is so important)

• Rails Heroku Migrate Unknown Error

  - by Ryan Max

  Hello. I am trying to get my app up and running on heroku. However once I go to migrate I get the following error: $ heroku rake db:migrate rake aborted! An error has occurred, this and all later migrations canceled: 530 5.7.0 Must issue a STARTTLS command first. bv42sm676794ibb.5 (See full trace by running task with --trace) (in /disk1/home/slugs/155328_f2d3c00_845e/mnt) == BortMigration: migrating ================================================= -- create_table(:sessions) -> 0.1366s -- add_index(:sessions, :session_id) -> 0.0759s -- add_index(:sessions, :updated_at) -> 0.0393s -- create_table(:open_id_authentication_associations, {:force=>true}) -> 0.0611s -- create_table(:open_id_authentication_nonces, {:force=>true}) -> 0.0298s -- create_table(:users) -> 0.0222s -- add_index(:users, :login, {:unique=>true}) -> 0.0068s -- create_table(:passwords) -> 0.0123s -- create_table(:roles) -> 0.0119s -- create_table(:roles_users, {:id=>false}) -> 0.0029s I'm not sure exactly what it means.

Additionally on Bort the Restful Authentication uses my gmail stmp to send confirmation emails...all the searches on google i do on STARTTLS have to do with stmp. Can someone point me in the right direction?

• Querying a database using Cocoa.

  - by S1syphus

  Hello everybody. Before I start a disclaimer, I should add a little disclaimer, that I am relatively new to Cocoa development and C in general. However I do have a copy of 'Cocoa Programming for Mac OS X 3rd edition' by Aaron Hillegass, which I am working through and using as a base, if anybody has a copy I am using the 'AmaZone' example on page 346 as a template and base. I trying to develop a small client app that takes a search string then displays results from a database accordingly. The database will contain a: list of files, their location, description & creation date, so for the moment the field number and types will remain the same. After looking around on SO, I saw something like: NSURL *myURL = [NSURL URLWithString:@"http://www.myserver.com/results.php"]; NSArray *sqlResults = [[NSArray alloc] initWithContentsOfURL:myURL]; I've worked with php before, so my current thinking after seeing this is create a php script on the server that queries the database, and creates an XML output. And with the XML response, just parse it. Would this be ok? as is there any major pitfalls anybody can see, that I can't. I know there are some database bundles, I've had a look at BaseTen for Postgres, but being relatively new to this, didn't want to get in over my head. Or if anybody else has any other suggestions and ideas, they would be greatly appreciated.

• NHibernate IQueryable Collection as Property of Root

  - by Khalid Abuhakmeh

  Hello and thank you for taking the time to read this. I have a root object that has a property that is a collection. For example : I have a Shelf object that has Books. // now public class Shelf { public ICollection<Book> Books {get; set;} } // want public class Shelf { public IQueryable<Book> Books {get;set;} } What I want to accomplish is to return a collection that is IQueryable so that I can run paging and filtering off of the collection directly from the the parent. var shelf = shelfRepository.Get(1); var filtered = from book in shelf.Books where book.Name == "The Great Gatsby" select book; I want to have that query executed specifically by NHibernate and not a get all to load a whole collection and then parse it in memory (which is what currently happens when I use ICollection). The reasoning behind this is that my collection could be huge, tens of thousands of records, and a get all query could bash my database. I would like to do this implicitly so that when NHibernate sees and IQueryable on my class it knows what to do. I have looked at NHibernates Linq provider and currently I am making the decision to take large collections and split them into their own repository so that I can make explicit calls for filtering and paging. Linq To SQL offers something similar to what I'm talking about.

• Can the Singleton be replaced by Factory?

  - by lostiniceland

  Hello Everyone There are already quite some posts about the Singleton-Pattern around, but I would like to start another one on this topic since I would like to know if the Factory-Pattern would be the right approach to remove this "anti-pattern". In the past I used the singleton quite a lot, also did my fellow collegues since it is so easy to use. For example, the Eclipse IDE or better its workbench-model makes heavy usage of singletons as well. It was due to some posts about E4 (the next big Eclipse version) that made me start to rethink the singleton. The bottom line was that due to this singletons the dependecies in Eclipse 3.x are tightly coupled. Lets assume I want to get rid of all singletons completely and instead use factories. My thoughts were as follows: hide complexity less coupling I have control over how many instances are created (just store the reference I a private field of the factory) mock the factory for testing (with Dependency Injection) when it is behind an interface In some cases the factories can make more than one singleton obsolete (depending on business logic/component composition) Does this make sense? If not, please give good reasons for why you think so. An alternative solution is also appreciated. Thanks Marc

• Can't Compile Correct Mapping File

  - by NoOne

  Hello, Im now developping one application in C# with Remoting objects and NHibernate. So here is a image explaining how my projects are divided. Views Layer This layer will be responsible for the users interface. This layer will always use the Controls Layer to create and edit objects; Control Layer This is my persistence layer, here Ill have all the NHibernate configuration. This is my critic point, because ListSingleton Project will have only my RemoteObject. (Here I have the App.config file) Models Layer Entity layer. Here I only have the entities classes and their respective mapping. I’ve done a test solution with no remoting and only with the projects of the Control and Model Layers. It was all working ok. Now that I added the Views Layer and set the solution to start with projects Client and Server (Client calls the Control Layer and this would do a try to persist a object) I’m getting a error at : Configuration cfg = new Configuration(); cfg.AddXmlFile("mapping/User.hbm.xml"); InnerException: {"Could not compile the mapping document: mapping/User.hbm.xml"} InnerException.InnerException: {"Could not find the dialect in the configuration"} StackTrace in the InnerException.InnerException " em NHibernate.Dialect.Dialect.GetDialect(IDictionary`2 props)\r\n em NHibernate.Cfg.Configuration.AddValidatedDocument(NamedXmlDocument doc)" But I know that there is no error in the mapping file because I used in my test application.

• Learning Clojure - What should I know about Java and more.

  - by kartan

  Hello, I have started learning Clojure recently, my main programming language is Ruby and I have no Java experience whatsoever. Which Java standard classes are a must to know when working with Clojure? Obviously Clojure doesn't come with a wrapper for everything and a lot of functionality is provided by Java's libraries. There's like a gazillion of them on javadocs - which ones should I explore? Where do I look for and how do I install third party libraries? In Ruby I'd visit Rubyforge or Rubytoolbox and then just gem install the package I found interesting. Which editor/ide for Clojure would you recommend (with the lowest learning curve)? I am trying to use Netbeans with Enclojure and paradoxally it's my biggest obstacle so far: Each generated project has some xml files, folders, library dependencies etc. the purpose of I have no clue. I am doing some labrepl exercises and wanted to try out some of the bundled libraries separately in a new project, but this simple task I cannot accomplish :/ Are there any clojure community driven blogs with news, code tips etc?

• Making a query result equal to zero when a condition is null

  - by John

  Hello, I believe the query below should work. However, when I run it, the results are blank. I think this is happening since for now, the table "comment" is empty. So there is no instance where s.submissionid = c.submissionid. I would like to have the query below to work even if there if no s.submissionid that equals a c.submissionid. In this case, I would like countComments to equal zero. How can I do this? Thanks in advance, John $sqlStr = "SELECT s.loginid, s.submissionid s.title, s.url, s.displayurl, l.username, count(c.comment) AS countComments FROM submission AS s, login AS l, comment AS c, WHERE s.loginid = l.loginid AND s.submissionid = c.submissionid GROUP BY s.loginid, s.submissionid s.title, s.url, s.displayurl, l.username ORDER BY s.datesubmitted DESC LIMIT 10"; $result = mysql_query($sqlStr); $arr = array(); echo "<table class=\"samplesrec\">"; while ($row = mysql_fetch_array($result)) { echo '<tr>'; echo '<td class="sitename1"><a href="http://www.'.$row["url"].'">'.$row["title"].'</a></td>'; echo '</tr>'; echo '<tr>'; echo '<td class="sitename2"><a href="http://www...com/sandbox/members/index.php?profile='.$row["username"].'">'.$row["username"].'</a><a href="http://www...com/sandbox/comments/index.php?submission='.$row["title"].'">'.$row["countComments"].'</a></td>'; echo '</tr>'; } echo "</table>";

• What's wrong with debugging in Eclipse on Android?

  - by Sebastian Dwornik

  I've obviously been spoiled by Visual Studio, because although I'm just learning Android and the Eclipse environment, debugging apps in Eclipse is becoming a serious detriment to further development. For example, Eclipse will compile this divide by zero just fine: public class Lesson2Main extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate (savedInstanceState); int i = 1 / 0; TextView tv = new TextView (this); tv.setText ("Hello, Android!"); setContentView (tv); } } And then, when it executes it under the debugger, I will get a full screen of useless debug info, non of which actually points me to the specific line containing the error. The stackTrace is null within the exception ('e') info tree, and it simply states a message stating 'ArithmeticException'. (that's nice, how about you point me in the direction of where you found it!?) I've looked all over the screen and am baffled that this IDE can't get this right. Does developing with Eclipse resort everyone back to 1991 with printf() like logging at every interval then to track down bugs? Seriously. Is there a configuration or plug-in that I'm missing to help with this? I haven't tested this case with XCode, but if the iPhone dev. IDE handles this more like Visual Studio, then no wonder the Android marketplace has so few apps. I'm excited about Android, but it seems that Eclipse is getting in the way.

• Setting nested object to null when selected option has empty value

  - by Javi

  Hello, I have a Class which models a User and another which models his country. Something like this: public class User{ private Country country; //other attributes and getter/setters } public class Country{ private Integer id; private String name; //other attributes and getter/setters } I have a Spring form where I have a combobox so the user can select his country or can select the undefined option to indicate he doen't want to provide this information. So I have something like this: <form:select path="country"> <form:option value="">-Select one-</form:option> <form:options items="${countries}" itemLabel="name" itemValue="id"/> </form:select> In my controller I get the autopopulated object with the user information and I want to have country set to null when the "-Select one-" option has been selected. So I have set a initBinder with a custom editor like this: @InitBinder protected void initBinder(WebDataBinder binder) throws ServletException { binder.registerCustomEditor(Country.class, "country", new CustomCountryEditor()); } and my editor do something like this: public class CustomCountryEditor(){ @Override public String getAsText() { //I return the Id of the country } @Override public void setAsText(String str) { //I search in the database for a country with id = new Integer(str) //and set country to that value //or I set country to null in case str == null } } When I submit the form it works because when I have country set to null when I have selected "-Select one-" option or the instance of the country selected. The problem is that when I load the form I have a method like the following one to load the user information. @ModelAttribute("user") public User getUser(){ //loads user from database } The object I get from getUser() has country set to a specific country (not a null value), but in the combobox is not selected any option. I've debugged the application and the CustomCountryEditor works good when setting and getting the text, thoughgetAsText method is called for every item in the list "countries" not only for the "country" field. Any idea? Is there a better way to set null the country object when I select no country option in the combobox? Thanks

• Google Maps, marker info window won't show up ?

  Hi guys, I have written this code that loops through an array of lat/long coordinates and places a marker at each of the coordinate. Everything forks fine, exempt the info window won't appear once the marker is clicked. var ExpTowerIcon = new GIcon(); ExpTowerIcon.image = "tower.png"; ExpTowerIcon.iconSize = new GSize(75, 75); ExpTowerIcon.iconAnchor = new GPoint(37, 65); ExpTowerIcon.infoWindowAnchor = new GPoint(37, 20); var marker=new Array(); for ( i=0 ; i < lat.length ; i++ ) { var MarkerPoint = new GLatLng(lat[i],long[i]); marker[i] = new GMarker(MarkerPoint,{icon:ExpTowerIcon}) map.addOverlay( marker[i] ); GEvent.addListener( marker[i] , 'click', function() { marker[i].openInfoWindowHtml('Hello!') ; }); var polyline = new GPolyline([ new GLatLng(lat[i],long[i]) , new GLatLng(lat[i+1],long[i+1]) ], "#ff0000", 5); map.addOverlay(polyline); } Any ideas? Thanks!

• Converting TrueClass / FalseClass to integer.

  - by Nick Gorbikoff

  Hello. I'm trying to figure out if there is an easy way to do the following short of adding to_i method to TrueClass/FalseClass. Here is a dilemma: I have a boolean field in my rails app - that is obviously stored as Tinyint in mysql. However - I need to generate xml based of the data in mysql and send it to customer - there SOAP service requires the field in question to have 0 or 1 as the value of this field. So at the time of the xml generation I need to convert my False to 0 and my True to 1 ( which is how they are stored in the DB). Since True & False lack to_i method I could write some if statement that generate either 1 or 0 depending on true/false state. However I have about 10 of these indicators and creating and if/else for each is not very DRY. So what you recommend I do? Or I could add a to_i method to the True / False class. But I'm not sure where should I scope it in my rails app? Just inside this particular model or somewhere else?

• Can I serialize an object if I didn't write the class used to instantiate that object?

  - by Richard77

  Hello, I've a simple class [Serializable] public class MyClass { public String FirstName { get; set: } public String LastName { get; set: } //Bellow is what I would like to do //But, it's not working //I get an exception ContactDataContext db = new ContactDataContext(); public void Save() { Contact contact = new Contact(); contact.FirstName = FirstName; contact.LastName = LastName; db.Contacts.InsertOnSubmit(contact); db.SubmitChanges(); } } I wanted to attach a Save method to the class so that I could call it on each object. When I introduced the above statement which contains ContactDataContext, I got the following error "In assembly ... PublicKeyToken=null' is not marked as serializable" It's clear that the DataContext class is generated by the framework (). I checked and did not see where that class was marked serialize. What can I do to overcome that? What's the rule when I'm not the author of a class? Just go ahead and mark the DataContext class as serializable, and pretend that everything will work? Thanks for helping

• java partial classes

  - by Dewfy

  Hello colleagues, Small preamble. I was good java developer on 1.4 jdk. After it I have switched to another platforms, but here I come with problem so question is strongly about jdk 1.6 (or higher :) ). I have 3 coupled class, the nature of coupling concerned with native methods. Bellow is example of this 3 class public interface A { public void method(); } final class AOperations { static native method(. . .); } public class AImpl implements A { @Override public void method(){ AOperations.method( . . . ); } } So there is interface A, that is implemented in native way by AOperations, and AImpl just delegates method call to native methods. These relations are auto-generated. Everything ok, but I have stand before problem. Sometime interface like A need expose iterator capability. I can affect interface, but cannot change implementation (AImpl). Saying in C# I could be able resolve problem by simple partial: (C# sample) partial class AImpl{ ... //here comes auto generated code } partial class AImpl{ ... //here comes MY implementation of ... //Iterator } So, has java analogue of partial or something like.

• scrolling and css align with "right: 0px"

  - by Gabi

  Hello, In an HTML page, if I align some <div>s with "right: 0px", they all look very nice, as I expect. However, if I make the browser window smaller and the horizontal scroll bar appears, when I scroll the page to the right, I see an unexpected white space (instead of the background colors of my <div>s). It seems that my <div>s are aligned relative to the visible area of the page. See the sample code below: <html> <head> <style> <!-- #parent { position: absolute; left: 0px; right: 0px; top: 0px; bottom: 0px; background-color: yellow; } #child { position: absolute; left: 100px; top: 300px; width: 1000px; height: 400px; background-color: blue; } --> </style> </head> <body> <div id="parent"><div id="child">some text here</div></div> </body> </html> Is there any way to make the "right: 0px" property align the controls relative to the size of the entire page, not only the visible area? Thanks.

• android python full integration

  - by Grzegorz Oledzki

  Is there a way to fully integrate Python with Java code on Android platform? Yes, I saw the question about running Python on Android and Android Scripting Environment (ASE). But that doesn't seem to be enough (correct me if I am wrong). I wanted to be able not only to invoke a Python script from within Java code, but have a full integration. The feature I need the most is the ability to have a state of execution of python code saved and be able to run several parts of code on demand against the same execution state. On JavaSE I would rely on Jython. I believe its simplest example shows it all (and some other features too, like something I would call variable state introspection): http://www.jython.org/archive/21/docs/embedding.html PythonInterpreter interp = new PythonInterpreter(); System.out.println("Hello, brave new world"); interp.exec("import sys"); interp.exec("print sys"); interp.set("a", new PyInteger(42)); interp.exec("print a"); interp.exec("x = 2+2"); PyObject x = interp.get("x"); System.out.println("x: "+x); System.out.println("Goodbye, cruel world"); Is it possible on Android? Is ASE a way to go?
