  • How do you use jQuery .data() to store html?

    - by Al
    Hi all - when I look up the syntax for .data(), it gives examples like this: $('body').data('foo', 52); I am doing AJAX loads and I was wondering if it is possible to store the incoming html using .data() so once the content is loaded, I would not need to do another AJAX load if the same link is clicked again - I would check to see if the .data key is empty. Would something like this work?: To load the contents of a #ajaxdiv into storage: $('body').data('storage', div#ajaxdiv.html()); To test if the data has already been loaded: if $('body').data('storage') != '' { div#ajaxdiv.html($('body').data('storage')); } Thanks in advance!!

  • MySQL insert at end of table

    - by Theopile
    Hello, I am using MySQL and PHP. I am having a problem with inserting a new item at the end of my table. When I insert the new item appears after the last created item, but I want it to be entered at the bottom of the table. Suppose that I have a table id=int,Primary Key and album=string and the table is: Wrath Crack The Skye Enter Shikari What would the MySQL query be if php variable $album=myAlbum was to be inserted next, at the end of the table, and with the appropriate id? Thanks

  • Ruby on Rails and database associations

    - by Marco
    Hi to all, I'm new to the Ruby world, and there is something unclear to me in defining associations between models. The question is: where is the association saved? For example, if i create a Customer model by executing: generate model Customer name:string age:integer and then i create an Order model generate model Order description:text quantity:integer and then i set the association in the following way: class Customer < ActiveRecord::Base has_many :orders end class Order < ActiveRecord::Base belongs_to :customer end I think here is missing something, for example the foreign key between the two entities. How does it handle the associations created with the keywords "has_many" and "belongs_to" ? Thanks

  • How to use application config file in C#?

    - by badpanda
    I am trying to use a config file in my C# console application. I created the file within the project by going New -- Application Configuration File, and naming it myProjectName.config. My config file looks like this: <?xml version="1.0" encoding="utf-8" ?> <configuration> <appSettings> <add key="SSDirectory" value="D:\Documents and Settings\****\MyDocuments\****" /> </appSettings> </configuration> The code to access it looks like this: private FileValidateUtil() { sSDirFilePath = ConfigurationSettings.AppSettings["SSDirectory"]; if (sSDirFilePath == null) Console.WriteLine("config file not reading in."); } Can anyone lend a hint as to why this is not working? (I am getting the error message.) Thanks!! badPanda

  • File Encrypt/Decrypt under load?

    - by chopps
    I found an interesting article about encrypting and decrypting files but since it uses a file.dat to store the key this will run into problems when theres alot of users on the site dealing with alot of files. http://www.codeproject.com/KB/security/VernamEncryption.aspx?display=Print Should a new file be created every time a file needs decrypting or would there be a better way to do this? UPDATE: Here is what im using to avoid the locking problems. using (Mutex FileLock = new Mutex(true, System.Guid.NewGuid().ToString())) { try { FileLock.WaitOne(); using (FileStream fs = new FileStream(keyFile, FileMode.Open)) { keyBytes = new byte[fs.Length]; fs.Read(keyBytes, 0, keyBytes.Length); } } catch (Exception ex) { EventLog.LogEvent(ex); } finally { FileLock.ReleaseMutex(); } } I tested it on 1000 TIFFs doing both encryption and decryption without any errors.

  • Is there a way to automate MS Office applications without license?

    - by james-h-l
    I am currently writing an application that will perform automation in Excel. I have MS Office (2007) installed on my work computer and the application is working fine referencing the the Microsoft Excel 12.0 Object Lirary. The target machine has the Office installed but not registered. It is one of those preinstalled editions. Attempting to run the application on the target machine I get an error saying Office is not installed? I'm assuming then you have to have a registed Office to use the object libraries? Is there anyway around this as I do not have a Office license key lying around and its quite expensive?

  • Posting to tumblr in PHP

    - by Sherif
    I am trying to make a test post to my tumblr blog with a php script (that will eventually be ran as a cron job) I have been browsing google and read many answers on here and the closest I found is explained in this post: Tumblr OAuth using PHP's OAuth class I am using the code in his tutorial here: http://vigrond.com/blog/2012/02/04/oauth-extension-php-and-the-tumblr-api/ Pretty much as is, replacing the blogurl with mine and of course the consumer and secret key. When I run the .php script via my browser however, nothing happens. Any ideas? EDIT: The only error I found in cPanel's error log is this: [Wed Oct 31 00:29:25 2012] [error] [client xx.xx.xx.xx ] PHP Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /path on line 14 But I fixed this and the error does not appear anymore.

  • Software protection

    - by anfono
    I want to protect my software from being used without permission. I will provide it for free to the parties I authorize to use it. Anyone knows a good protection scheme against having it copied and run by unauthorized parties ? So far, I thought about introducing a key validation mechanism: periodically, the user needs to send me (web site query) a code based on which I generate a new code that app validates against. There is an initial code, and so I can track users... Thoughts ? Later edit: I changed the licensing part to avoid unfocused discussion.

  • Is there a name for the technique of using base-2 numbers to encode a list of unique options?

    - by Lunatik
    Apologies for the rather vague nature of this question, I've never been taught programming and Google is rather useless to a self-help guy like me in this case as the key words are pretty ambiguous. I am writing a couple of functions that encode and decode a list of options into a Long so they can easily be passed around the application, you know this kind of thing: 1 - Apple 2 - Orange 4 - Banana 8 - Plum etc. In this case the number 11 would represent Apple, Orange & Plum. I've got it working but I see this used all the time so assume there is a common name for the technique, and no doubt all sorts of best practice and clever algorithms that are at the moment just out of my reach.

  • Why can't I find DataTemplates in merged resource dictionaries?

    - by dthrasher
    In my MainWindow.xaml, I have the following reference to a ResourceDictionary: <Window.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="MainSkin.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Window.Resources> In MainSkin.xaml, I define a datatemplate: <DataTemplate x:Key="TagTemplate"> ... </DataTemplate> Deeper within my application, I attempt to use this data template: <ContentControl DataContext="{Binding Tag}" ContentTemplate="{StaticResource TagTemplate}"/> The code compiles successfully, but when I attempt to load a Page or UserControl that contains this StaticResource, I get an exception saying that the TagTemplate can't be found. What am I doing wrong?

  • I'm looking for a constraint to prevent the insert of an empty string in MySQL

    - by Marga Keuvelaar
    Ok, in this question I learned how to prevent the insert of a NULL value. But, unfortunately, an empty string is being inserted anyway. Apart from preventing this on the PHP side, I'd like to use something like a database constraint to prevent this. Of course a check on the application side is necessary, but I'd like it to be on both sides. I am taught that whatever application is talking to your database, it should not be able to insert basically wrong data in it. So... CREATE TABLE IF NOT EXISTS tblFoo ( foo_id int(11) NOT NULL AUTO_INCREMENT, foo_test varchar(50) NOT NULL, PRIMARY KEY (foo_id) ); Would still allow me to do this insert: INSERT INTO tblFoo (foo_test) VALUES (''); Which I would like to prevent.

  • Order database results by bayesian rating

    - by One Trick Pony
    I'm not sure this is even possible, but I need a confirmation before doing it the "ugly" way :) So, the "results" are posts inside a database which are stored like this: the posts table, which contains all the important stuff, like the ID, the title, the content the post meta table, which contains additional post data, like the rating (this_rating) and the number of votes (this_num_votes). This data is stored in pairs, the table has 3 columns: post ID / key / value. It's basically the WordPress table structure. What I want is to pull out the highest rated posts, sorted based on this formula: br = ( (avg_num_votes * avg_rating) + (this_num_votes * this_rating) ) / (avg_num_votes + this_num_votes) which I stole form here. avg_num_votes and avg_rating are known variables (they get updated on each vote), so they don't need to be calculated. Can this be done with a mysql query? Or do I need to get all the posts and do the sorting with PHP?

  • How to bind a complex dictionary to a Gridview in asp.net?

    - by Mehdi
    I've used an early binding of a dictionary<string, string> to a gridview to show Urls Text and its HRef as key-value and it works like a charm. But since I want to replace the dictionary with this one : dictionary<string, LinkInfo> the binding goes wrong! Should I handle some events like as onItemDataBound or something? and the LinkInfo structure is: public struct LinkInfo{ public string href; public bool Enabled; }

  • Revisions: algorithm and data structure

    - by SODA
    Hi, I need ideas for structuring and processing data with revisions. For example, I have a database of objects (e.g. cars). Each object has a number of properties, which can be arbitrary, so there's no a set schema to describe these objects. These objects are probably saved as key-value pairs. Now I need to change property of an object. I don't want to completely rewrite it - I want to be able to go back and see history of changes to these properties, that's why I want to add new property and keep the old one (so I guess a timestamp would do the job of telling which property is the latest). At the same time I want to be able to get info about any object in a snap, with only latest versions of each of the properties. Any ideas what would be the best approach? At least please point me in the right direction. Thanks!

  • How does this Perl grep work to determine the union of several hashes?

    - by titaniumdecoy
    I don't understand the last line of this function from Programming Perl 3e. Here's how you might write a function that does a kind of set intersection by returning a list of keys occurring in all the hashes passed to it: @common = inter( \%foo, \%bar, \%joe ); sub inter { my %seen; for my $href (@_) { while (my $k = each %$href) { $seen{$k}++; } } return grep { $seen{$_} == @_ } keys %seen; } I understand that %seen is a hash which maps each key to the number of times it was encountered in any of the hashes provided to the function.

  • How to By Pass Request Validation

    - by GIbboK
    Hi, I have a GridView and I need update some data inserting HTML CODE; I would need this data been stored encoded and decoded on request. I cannot in any way disable globally "Request Validation" and not even at Page Level, so I would need a solution to disable "Request Validation" at Control Level. At the moment I am using a script which should Html.Encode every value being update, butt seems that "Request Validation" start its job before event RowUpdating, so I get the Error "Page A potentially dangerous Request.Form ... ". Any idea how to solve it? Thanks protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e) { foreach (DictionaryEntry entry in e.NewValues) { e.NewValues[entry.Key] = Server.HtmlEncode(entry.Value.ToString()); } PS I USE Wweb Controls not MVC

  • HBase as web app backend

    - by NathanD
    Can anyone advise if it is a good idea to have HBase as primary data source for web-based application? My primary concern is HBase's response time to queries. Is it possible to have sub-second response? edit: more details about the app itself. Amount of data: ~500GB of text data, expect to reach 1TB soon Number of concurrent users using the app: up to 50 The app will be used to present reports about data stored in HBase, like how many times keyword "X" occured in last 24h. For ~80% of requests from that app I will know the exact key, 20% will be scans (I'm looking into HBase schema design related topics to make it run fast)

  • Handling auto-incrementing IDENTITY SQL Server fields with LINQ to SQL in C#

    - by Maxim Z.
    I'm building an ASP.NET MVC site that uses LINQ to SQL to connect to SQL Server, where I have a table that has an IDENTITY bigint primary key column that represents an ID. In one of my code methods, I need to create an object of that table to get its ID, which I will place into another object based on another table (FK-to-PK relationship). At what point is the IDENTITY column value generated and how can I obtain it from my code? Is the right approach to: Create the object that has the IDENTITY column Do an InsertOnSubmit() and SubmitChanges() to submit the object to the database table Get the value of the ID property of the object

  • how to order a group result with Linq?

    - by Aaron
    How can I order the results from "group ... by... into..." statement in linq? For instance: var queryResult = from records in container.tableWhatever where records.Time >= DateTime.Today group records by tableWhatever.tableHeader.UserId into userRecords select new { UserID = userRecords.Key, Records = userRecords }; The query returns records in table "contain.tableWhatever" grouped by "UserId". I want the returned results within each group ordered by time decending. How can I do that? More specific, assume the above query return only one group like the following: {UserID = 1, Records= {name1 5/3/2010_7:10pm; name2 5/3/2010_8:10pm; name3 5/3/2010_9:10pm} } After insert the orderby statement in the above query, the returned results should be like this: {UserID = 1, Records= {name3 5/3/2010_9:10pm; name2 5/3/2010_8:10pm; name1 5/3/2010_7:10pm} } Thanks for help!

  • Oracle SQL Update query takes days to update

    - by B Senthil Kumar
    I am trying to update a record in the target table based on the record coming in from source. For instance, if the incoming record is present in the target table I would update them in the target else I would simply insert. I have over one million records in my source while my target has 46 million records. The target table is partitioned based on calendar key. I implement this whole logic using Informatica. I find that the Informatica code is perfectly fine looking at the Informatica session log but its in the update it takes long time (more than 5 days to update one million records). Any suggestions as to what can be done on the scenario to improve the performance?

  • ANDROID. Emulate Hardware Keys with an IME. Doesn't work with Dialog and Spinner

    - by shutdown11
    I have understand that the only way to inject KeyEvents in the Android System is to implement an Input Method. I have created my IME with the purpose to control from remote the device. I emulate the hardware keys using the method private void keyDownUp(int keyEventCode) { getCurrentInputConnection().sendKeyEvent( new KeyEvent(KeyEvent.ACTION_DOWN, keyEventCode)); getCurrentInputConnection().sendKeyEvent( new KeyEvent(KeyEvent.ACTION_UP, keyEventCode)); } in my class that extends InputMethodService. It works fine until an AlertDialog, or the menu of a Spinner comes in foreground. Also the windows that appears when the Menu key is problematic. My IME can't get focus on them, and the keyevents are sent to the activity behind them. Using hardware keys, the Dialog get the focus and you can select the botton on the Dialog. How can i emulate that, using the IME(or anything else)?

  • STL map containing references does not compile

    - by MTsoul
    The following: std::map<int, ClassA &> test; gives: error C2101: '&' on constant While the following std::map<ClassA &, int> test; gives error C2528: '_First' : pointer to reference is illegal The latter seems like map cannot contain a reference for the key value, since it needs to instantiate the class sometimes and a reference cannot be instantiated without an object. But why does the first case not work?
