• Script/plugin to update web page (load next 25 comments) until page fully loaded

  - by Carl

  Brief summary: I need a script/plugin for Firefox that selects the "load next 25 comments" link at the bottom of a web page, until that link is no longer on the page. As you click that link - you get more comments - eventually all of them on the same page. See this web page for an example (there are 1,852 comments): http://www.cnn.com/2010/US/05/16/gulf.oil.spill/index.html#comment-50598247 I have a regular problem with CNN.com. I post comments there. People sometimes reply to them. I check my profile, and see the number of replies, but I can't read them there. I have to follow the link to the original article. The fist set of comments are at the bottom, with a 'load next 25' link at the bottom. There are often hundreds of comments, and sometimes a few thousand. There is no practical way for me to read the replies to my comments. If there's under around 300 hundred, I'll just click that link enough times to see what the replies to my comments are. I need a script/plugin to select that 'load next 25' link until that link is no longer present on the page. Then I could just search for my userid and read the responses.

• Use MySQL trigger to update another table when duplicate key found

  - by Jason

  Been scratching my head on this one, hoping one of you kind people and direct me towards solving this problem. I have a mysql table of customers, it contains a lot of data, but for the purpose of this question, we only need to worry about 4 columns 'ID', 'Firstname', 'Lastname', 'Postcode' Problem is, the table contains a lot of duplicated customers. A new table is being created where each customer is unique and for us, we decide a unique customer is based on 'Firstname', 'Lastname' and 'Postcode' However, (this is the important bit) we need to ensure each new "unique" customer record also can be matched to the original multiple entries of that customer in the original table. I believe the best way to do this is to have a third table, that has 'NewUniqueID', 'OldCustomerID'. So we can search this table for 'NewUniqueID' = '123' and it would return multiple 'OldCustomerID' values where appropriate. I am hoping to make this work using a trigger and the on duplicate key syntax. So what would happen is as follows: An query is run taking the old customer table and inserting it in to the new unique table. (A standard Insert Select query) On duplicate key continue adding records, but add one entry in to the third table noting the 'NewUniqueID' that duped along with the 'OldCustomerID' of the record we were trying to insert. Hope this makes sense, my apologies if it isn't clear. I welcome and appreciate any thoughts on this one! Many thanks Jason

• UITableViewCell checkmarks

  - by burki

  Hi! When you select a cell in the UITableView, the - (void)tableView:(UITableView *)table didSelectRowAtIndexPath:(NSIndexPath *)indexPath is called. There some of the NSManagedObjects will be updated with the right values and the row will be deselected. Well, it works all right, but you can't see any selection of the tableviewcell. I found out that the access on core data causes the problem, that means, if i comment out the lines with the commands of updating the NSManagedObjects, it all works like I want, with a smooth selection and deselection. Can anybody help? Thanks. - (void)tableView:(UITableView *)table didSelectRowAtIndexPath:(NSIndexPath *)indexPath { //[table deselectRowAtIndexPath:indexPath animated:YES]; NSMutableSet *favoriteGroups = [NSMutableSet setWithSet:element.favoriteGroup]; NSMutableSet *elements = [NSMutableSet setWithSet:[(FavoriteGroup *)[fetchedResultsController objectAtIndexPath:indexPath] element]]; UITableViewCell *checkedCell = [table cellForRowAtIndexPath:indexPath]; if (checkedCell.accessoryType == UITableViewCellAccessoryCheckmark) { [elements removeObject:element]; [favoriteGroups removeObject:[fetchedResultsController objectAtIndexPath:indexPath]]; [[table cellForRowAtIndexPath:indexPath] setAccessoryType:UITableViewCellAccessoryNone]; } else { [elements addObject:element]; [favoriteGroups addObject:[fetchedResultsController objectAtIndexPath:indexPath]]; [[table cellForRowAtIndexPath:indexPath] setAccessoryType:UITableViewCellAccessoryCheckmark]; } element.favoriteGroup = favoriteGroups; FavoriteGroup *favoriteGroup = [self.fetchedResultsController objectAtIndexPath:indexPath]; favoriteGroup.element = elements; [self.tableView deselectRowAtIndexPath:indexPath animated:YES]; }

• node.js: looping, email each matching row from query but it it emails the same user by # number of matches?

  - by udonsoup16

  I have a node.js email server that works fine however I noticed a problem. If the query string found 4 rows, it would send four emails but only to the first result instead of to each found email address. var querystring1 = 'SELECT `date_created`,`first_name`,`last_name`,`email` FROM `users` WHERE TIMESTAMPDIFF(SECOND,date_created, NOW()) <=298 AND `email`!="" LIMIT 0,5'; connection.query(querystring1, function (err, row) { if (err) throw err; for (var i in row) { // Email content; change text to html to have html emails. row[i].column name will pull relevant database info var sendit = { to: row[i].email, from: '******@******', subject: 'Hi ' + row[i].first_name + ', Thanks for joining ******!', html: {path:__dirname + '/templates/welcome.html'} }; // Send emails transporter.sendMail(sendit,function(error,response){ if (error) { console.log(error); }else{ console.log("Message sent1: " + row[i].first_name);} transporter.close();} ) }}); .... How do I have it loop through each found row and send a custom email using row data individual row data?

• question about MySQL transaction and trigger

  - by WilliamLou

  I quickly browsed MySQL manual but didn't find the exact information about my question. Here is my question: if I have a InnoDB table A with two triggers triggered by 'AFTER INSERT ON A' and 'AFTER UPDATE ON A'. More specifically, For example: one trigger is defined as: CREATE TRIGGER test_trigger AFTER INSERT ON A FOR EACH ROW BEGIN INSERT INTO B SELECT * FROM A WHERE A.col1 = NEW.col1 END; You can ignore the query between BEGIN AND END, basically I mean this trigger will insert several rows into table B which is also a InnoDB table. Now, if I started a transaction and then insert many rows, say: 10K rows, into table A. If there is no trigger associated with table A, all these inserts are atomic, that's for sure. Now, if table A is associated with several insert/update triggers which insert/update many rows to table B and/or table C etc.. will all these inserts and/or updates are still all atomic? I think it's still atomic, but it's kind of difficult to test and I can't find any explanations in the Manual. Anyone can confirm this? Thanks a lot!

• In mysql, is "explain ..." always safe?

  - by tye

  If I allow a group of users to submit "explain $whatever" to mysql (via Perl's DBI using DBD::mysql), is there anything that a user could put into $whatever that would make any database changes, leak non-trivial information, or even cause significant database load? If so, how? I know that via "explain $whatever" one can figure out what tables / columns exist (you have to guess names, though) and roughly how many records are in a table or how many records have a particular value for an indexed field. I don't expect one to be able to get any information about the contents of unindexed fields. DBD::mysql should not allow multiple statements so I don't expect it to be possible to run any query (just explain one query). Even subqueries should not be executed, just explained. But I'm not a mysql expert and there are surely features of mysql that I'm not even aware of. In trying to come up with a query plan, might the optimizer actual execute an expression in order to come up with the value that an indexed field is going to be compared against? explain select * from atable where class = somefunction(...) where atable.class is indexed and not unique and class='unused' would find no records but class='common' would find a million records. Might 'explain' evaluate somefunction(...)? And then could somefunction(...) be written such that it modifies data?

• why does cx_oracle execute() not like my string now?

  - by Frank Stallone

  I've downloaded cx_oracle some time ago and wrote a script to convert data to XML. I've had to reisntall my OS and grabbed the latest version of cx_Oracle (5.0.3) and all of the sudden my code is broken. The first thing was that cx_Oracle.connect wanted unicode rather string for the username and password, that was very easy to fix. But now it keeps failing on the cursor.execute and tells me my string is not a string even when type() tells me it is a string. Here is a test script I initally used ages ago and worked fine on my old version but does not work on cx_Oracle now. import cx_Oracle ip = 'url.to.oracle' port = 1521 SID = 'mysid' dsn_tns = cx_Oracle.makedsn(ip, port, SID) connection = cx_Oracle.connect(u'name', u'pass', dsn_tns) cursor = connection.cursor() cursor.arraysize = 50 sql = "select isbn, title_code from core_isbn where rownum<=20" print type(sql) cursor.execute(sql) for isbn, title_code in cursor.fetchall(): print "Values from DB:", isbn, title_code cursor.close() connection.close() When I run that I get: Traceback (most recent call last): File "C:\NetBeansProjects\Python\src\db_temp.py", line 48, in cursor.execute(sql) TypeError: expecting None or a string Does anyone know what I may be doing wrong?

• entity framework insert bug

  - by tmfkmoney

  I found a previous question which seemed related but there's no resolution and it's 5 months old so I've opened my own version. http://stackoverflow.com/questions/1545583/entity-framework-inserting-new-entity-via-objectcontext-does-not-use-existing-e When I insert records into my database with the following it works fine for a while and then eventually it starts inserting null values in the referenced field. This typically happens after I do an update on my model from the database although not always after I do an update. I'm using a MySQL database for this. I have debugged the code and the values are being set properly before the save event. They're just not getting inserted properly. I can always fix this issue by re-creating the model without touching any of my code. I have to recreate the entire model, though. I can't just dump the relevant tables and re-add them. This makes me think it doesn't have anything to do with my code but something with the entity framework. Does anyone else have this problem and/or solved it? using (var db = new MyModel()) { var stocks = from record in query let ticker = record.Ticker select new { company = db.Companies.FirstOrDefault(c => c.ticker == ticker), price = Convert.ToDecimal(record.Price), date_stamp = Convert.ToDateTime(record.DateTime) }; foreach (var stock in stocks) { if (stock.company != null) { var price = new StockPrice { Company = stock.company, price = stock.price, date_stamp = stock.date_stamp }; db.AddToStockPrices(price); } } db.SaveChanges(); }

• Which isolation level should I use for the following insert-if-not-present transaction?

  - by Steve Guidi

  I've written a linq-to-sql program that essentially performs an ETL task, and I've noticed many places where parallelization will improve its performance. However, I'm concerned about preventing uniquness constraint violations when two threads perform the following task (psuedo code). Record CreateRecord(string recordText) { using (MyDataContext database = GetDatabase()) { Record existingRecord = database.MyTable.FirstOrDefault(record.KeyPredicate()); if(existingRecord == null) { existingRecord = CreateRecord(recordText); database.MyTable.InsertOnSubmit(existingRecord); } database.SubmitChanges(); return existingRecord; } } In general, this code executes a SELECT statement to test for record existance, followed by an INSERT statement if the record doesn't exist. It is encapsulated by an implicit transaction. When two threads run this code for the same instance of recordText, I want to prevent them from simultaneously determining that the record doesn't exist, thereby both attempting to create the same record. An isolation level and explicit transaction will work well, except I'm not certain which isolation level I should use -- Serializable should work, but seems too strict. Is there a better choice?

• Doubly Linked Lists Implementation

  - by user552127

  Hi All, I have looked at most threads here about Doubly linked lists but still unclear about the following. I am practicing the Goodrich and Tamassia book in Java. About doubly linked lists, please correct me if I am wrong, it is different from a singly linked list in that a node could be inserted anywhere, not just after the head or after the tail using both the next and prev nodes available, while in singly linked lists, this insertion anywhere in the list is not possible ? If one wants to insert a node in a doubly linked list, then the default argument should be either the node after the to-be inserted node or node before the to-be inserted node ? But if this is so, then I don't understand how to pass the node before or after. Should we be displaying all nodes that were inserted till now and ask the user to select the node before or after which some new node is to be inserted ? My doubt is how to pass this default node. Because I assume that will require the next and prev nodes of these nodes as well. For e.g, Head<-A<-B<-C<-D<-E<-tail If Z is the new node to be inserted after say D, then how should node D be passed ? I am confused with this though it seems pretty simple to most. But pl do explain. Thanks, Sanjay

• JPanel not listening to key event when there is a child component with JButton on it

  - by Yifu

  I'm working on a map editor for my college project. And I had a problem that the map panel is not listening key event while it should. This happens when I add a ToolBarPane (which extends JPanel) with JComponent such as JButton, JComboBox that implements ActionListener on it AND the map panel (which extends the JPanel) together on to the Frame (I used BorderLayout). I have System.out.println statement to test if the key press is received, and it's not printing, if I remove the ToolBar, the key listener works again, so is the mouseListenner is disabled just like the keyListener, which means I can't handle press events etc, but the mouseListener works fine and I can still handle mouse move event. Here is a screen shot how it works without the ToolBarPane http://img684.imageshack.us/img684/3232/sampleku.png note that you can use the mouse to put images on the map, you can also select images using the mouse just like a laser tool, and by pressing number key you can switch between different images, this works fine until I add the ToolBarPane which shows like this: img291.imageshack.us/img291/8020/failve.png (please add http before that, i can only post one hyperlink) (I can't post images here cuz im a new user) With the ToolBarPane on I was no longer able to handle the key event. I guess it might by that the focus as been transfered to that panel somehow, but not sure at all. Does and body know this and can help me out? Thanks very much

• How do I rescue a small portion of data from a SQL Server database backup?

  - by Greg

  I have a live database that had some data deleted from it and I need that data back. I have a very recent copy of that database that has already been restored on another machine. Unrelated changes have been made to the live database since the backup, so I do not want to wipe out the live database with a full restore. The data I need is small - just a dozen rows - but those dozen rows each have a couple rows from other tables with foreign keys to it, and those couple rows have god knows how many rows with foreign keys pointing to them, so it would be complicated to restore by hand. Ideally I'd be able to tell the backup copy of the database to select the dozen rows I need, and the transitive closure of everything that they depend on, and everything that depends on them, and export just that data, which I can then import into the live database without touching anything else. What's the best approach to take here? Thanks. Everyone has mentioned sp_generate_inserts. When using this, how do you prevent Identity columns from messing everything up? Do you just turn IDENTITY INSERT on?

• Should i write my own forum? If my site has banning/PM/etc?

  - by acidzombie24

  I built a site from scratch (already done). It has banning, PM, comments, etc. The PMs and comments are done using markdown (like SO system). Should i write my own forum code or should i find one already made? What are reasons for or against writing my own? There are pros and cons for writing my own or using another software. But some cons keeping me from using another forum software is Multiple Logins: One for the site, one for separate forums. Need to Customization code: I'll need to change the toolbar in the forum software so i can access pages on the regular site. Look consistency: It may look drastically different from my site even after applying lots of css changes. Banning and User consistency. Users may be ban on site or on forums but not the other. users may select a different or multiple usernames on the forum instead of being forced to use the same username on both site and forum. What are reasons for or against writing my own and using forum software?

• we would like the user to be able to pick a file from native file system and drag & drop it to our a

  - by user261740

  We have an existing java desktop application which starts, when user click on our application icon (placed on desktop) OR double click on executable(.exe). It opens the frame which allows user to select the file from native file system and uploads it to the server. Now we would like to facilitate user, that he can pick a file from windows explorer and drag it to the "shortcut / Application icon" & drop it on the "shortcut / Application icon" on the desktop. This would start the uploading of that file on the server. we need to capture the action of "drop" and launch on shortcut.. which may be completely not related to java, it can be very generic to any application. We are using JSmooth to build an executable from jar and NSIS for installer purpose. I would like to know.. How we can launch the application if user drops local file onto the system icon ? How we get the absolute path of file name which has been dropped onto the executable ?

• How to stop the submission of the form using JQUERY?

  - by Param-Ganak

  Hello frineds! I have a form which have many check boxes in it. User will check one or many checkboxes and click on Delete button which is actually submit button then the respective records for selected check boxes are get deleted. Required operation steps are as follows:- When user selects one or more checkboxes and clicks the submit button then a JQUERY code is get executed in which It should checks that if any check box is selected; if not; then is displays alert message and do not submit the form. If it founds that one or more checkboxes are selected it should ask user for his/her confirmation using confirm alert box about the confirmation of deletion. If user press YES button on confirm box then it should submit the form using javascript submit statement. If user pressed the NO button then it should unchecks the checked selected checkboxes and should not submit the form. This is the JQUERY code I had written. $(document).ready(function (){ $("#id_delete").click(function(){ var temp=$("#id_frm input:checkbox:checked"); var len=temp.length; if(len==0) { alert("Please select the order."); } else { if(confirm("Are you sure to delete the selected orders.")) { $("#id_frm").submit(); } else { temp.checked=false; } } }); }); Problems: This code is not working properly. Here 1. It submits form when there is no check box is selected. 2. It submits the form when user press NO button on confirmation dialog box. Please guide me friends in this problem.

• How to iterate JPA collections in Google App engine

  - by palto

  Hi I use Google App Engine with datanucleus and JPA. I'm having a real hard time grasping how I'm supposed to read stuff from data store and pass it to JSP. If I load a list of POJOs with entitymanager and pass it to JSP, it crashes to org.datanucleus.exceptions.NucleusUserException: Object Manager has been closed. I understand why this is happening. Obviously because I fetch the list, close the entity manager and pass it to JSP, at which point it will fail because the list is lazy. How do I make the list NOT lazy without resorting to hacks like calling size() or something like that? Here is what I'm trying to do: @Override protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { req.setAttribute("parties", getParties()); RequestDispatcher dispatcher = getServletContext().getRequestDispatcher("/WEB-INF/parties.jsp"); dispatcher.forward(req, resp); } private List<Party> getParties(){ EntityManager em = entityManagerProvider.get(); try{ Query query = em.createQuery("SELECT p FROM Party p"); return query.getResultList(); }finally{ em.close(); } }

• Super inplace controls in_place_select displays incorrectly

  - by Magicked

  I'm using the super_inplace_controls plugin to allow users to edit fields on the "show" page. However, I'm running into an issue with the in_place_select function. Here is my view: <p> <b>Status:</b> <%= in_place_select :incident, :incident_status, :choices => @statuses.map { |e| [e.name, e.id] } %> </p> This is in the 'Incident' view. IncidentStatus is a separate table that has_many Incidents. In the Incident controller, I retrieve @statuses like so: @statuses = IncidentStatus.find(:all) Everything works fine for the in_place_select, except the original display. In my browser, it shows: Status: #<IncidentStatus:0x1033147d8> Which means it's not grabbing the current incident_status.name, but it's just changing the object to a string. I'm not sure how to fix this! When I click on the "IncidentStatus:0x1033147d8", everything works properly and I can select the proper fields. Thanks for any help!

• Using ms: xpath functions inside XPathExpression

  - by Filini

  I am trying to use Microsoft XPath Extension Functions (such as ms:string-compare http://msdn.microsoft.com/en-us/library/ms256114.aspx) inside an XPathExpression object. These functions are extensions inside the MSXML library, and if I use them in an XslCompiledTransform (simply adding the "ms" namespace) they work like a charm: var xsl = @" <?xml version=""1.0"" encoding=""UTF-8""?> <xsl:stylesheet version=""2.0"" xmlns:xsl=""http://www.w3.org/1999/XSL/Transform"" xmlns:xs=""http://www.w3.org/2001/XMLSchema"" xmlns:fn=""http://www.w3.org/2005/xpath-functions"" xmlns:ms=""urn:schemas-microsoft-com:xslt""> <xsl:output method=""xml"" version=""1.0"" encoding=""UTF-8"" indent=""yes""/> <xsl:template match=""/Data""> <xsl:element name=""Result""> <xsl:value-of select=""ms:string-compare(@timeout1, @timeout2)""/> </xsl:element> </xsl:template> </xsl:stylesheet>"; var xslDocument = new XmlDocument(); xslDocument.LoadXml(xsl); var transform = new XslCompiledTransform(); transform.Load(xslDocument); Then I tried using them in an XPathExpression: XPathNavigator nav = document.DocumentElement.CreateNavigator(); XPathExpression expr = nav.Compile("ms:string-compare(/Data/@timeout1, /Data/@timeout2)"); XmlNamespaceManager manager = new XmlNamespaceManager(document.NameTable); manager.AddNamespace("ms", "urn:schemas-microsoft-com:xslt"); expr.SetContext(manager); nav.Evaluate(expr); But I get an exception "XsltContext is needed for this query because of an unknown function". XsltContext is a specific XmlNamespaceManager, but I don't know if it's possible to instantiate it without an actual XslCompiledTransform (it's abstract) and use it as my expression context. Is there any way to do this (or any other way to use ms: extensions inside an XPathExpression)?
