  • Sending a JSON array to be received as a Dictionary<string,string>

    - by James Bond
    I have a method with the following signature: public ActionResult RenderFamilyTree(string name, Dictionary<string, string> children) I'm trying to call it from javascript using jQuery like this: $('#div_render').load( "<%= Url.Action("RenderFamilyTree") %>", { 'name': 'Raul', [ {'key':'key1','value':'value1'}, {'key':'key2','value':'value2'} ] }, function() { alert('Loaded'); } ); Am I missing something to get this to work?

  • How do I store a Java KeyStore password?

    - by Anthony D
    In my web application I access a private key that is stored in a Java KeyStore. I would like to know what is the best/recommended way to store the password for the KeyStore and private key. I've considered using a properties file but that does not seem very secure for use in a production environment (storing password in a plain text file). Also, hard-coding the password in my code is not an option I'm willing to entertain. Thanks.

  • dictionary interface for large data sets

    - by Richard
    I have a set of key/values (all text) that is too large to load in memory at once. I would like to interact with this data via a Python dictionary-like interface. Does such a module already exist? Reading key values should be efficient and values compressed on disk to save space.

  • Suggestion for a Data Structure!

    - by Jay
    I have the following requirements for a data structure: Direct access to an element with the help of a key (Key will be an integer, range is also same as integer range) Avoid memory allocation in chunks (Allocate contigous memory for the data structure including the data) Should be able to grow the data structure size dynamically Which data structure would you suggest? Any pointers in the direction will also be of help.

  • Loop through multi-dimensional array and remove certain keys

    - by Webkungen
    Hi! I've got a nested tree structure which is based on the array below: Array ( [1] = Array ( [id] = 1 [parent] = 0 [name] = Startpage [uri] = 125 [basename] = index.php [child] = ) [23] = Array ( [id] = 23 [parent] = 0 [name] = Events [uri] = 0 [basename] = [child] = Array ( [24] = Array ( [id] = 24 [parent] = 23 [name] = Public news [uri] = 0 [basename] = [child] = Array ( [27] = Array ( [id] = 27 [parent] = 24 [name] = Add [uri] = 100 [basename] = news.public.add.php [child] = ) [28] = Array ( [id] = 28 [parent] = 24 [name] = Overview [uri] = 101 [basename] = news.public.overview.php [child] = ) ) ) [25] = Array ( [id] = 25 [parent] = 23 [name] = Private news [uri] = 0 [basename] = [child] = Array ( [29] = Array ( [id] = 29 [parent] = 25 [name] = Add [uri] = 67 [basename] = news.private.add.php [child] = ) [30] = Array ( [id] = 30 [parent] = 25 [name] = Overview [uri] = 68 [basename] = news.private.overview.php [child] = ) ) ) [26] = Array ( [id] = 26 [parent] = 23 [name] = Calendar [uri] = 0 [basename] = [child] = Array ( [31] = Array ( [id] = 31 [parent] = 26 [name] = Add [uri] = 69 [basename] = news.event.add.php [child] = ) [32] = Array ( [id] = 32 [parent] = 26 [name] = Overview [uri] = 70 [basename] = news.event.overview.php [child] = ) ) ) ) ) ) I'm looking for a function to loop (recursive?) through the array and remove some keys. I my system I can allow users to certain functions/pages and if I deny access to the whole "block" "Events", the array will look like this: Array ( [1] = Array ( [id] = 1 [parent] = 0 [name] = Startpage [uri] = 125 [basename] = index.php [child] = ) [23] = Array ( [id] = 23 [parent] = 0 [name] = Events [uri] = 0 [basename] = [child] = Array ( [24] = Array ( [id] = 24 [parent] = 23 [name] = Public news [uri] = 0 [basename] = [child] = ) [25] = Array ( [id] = 25 [parent] = 23 [name] = Private news [uri] = 0 [basename] = [child] = ) [26] = Array ( [id] = 26 [parent] = 23 [name] = Calendar [uri] = 0 [basename] = [child] = ) ) ) ) As you can see above, the whole "block" "Events" is useless right now, becuase there is no page associated with each option. So I need to find all "keys" where "basename" is null AND where child is not an array or where the array is empty and remove them. I found this function when searching the site: function searchAndDestroy(&$a, $key, $val){ foreach($a as $k = &$v){ if(is_array($v)){ $r = searchAndDestroy($v, $key, $val); if($r){ unset($a[$k]); } }elseif($key == $k && $val == $v){ return true; } } return false; } It can be used to remove a key any where in the array, but only based in one thing, for example remove all keys where "parent" equals "23". But I need to find and remove (unset) all keys where "basename" is null AND where child isn't an array or where the array is empty. Can anyone help me out and possibly tweak the function above? Thank you,

  • Cache SHA1 digest result?

    - by johnathan
    I'm storing several versions of a file based on a digest of the original filename and its version, like this: $filename = sha1($original . ':' . $version); Would it be worth it to cache the digest ($filename) in memcache as a key/value pair (the key being the original + version and value the sha1 hash), or is generating the digest quick enough (for a high traffic php web app)? Thanks, Johnathan

  • What does get-task-allow do in Xcode?

    - by Mr. Matt
    So when I set up my entitlements in my iPhone app project, I create a new Entitlements.plist, and set the value of get-task-allow to false. But why? What does this key represent? EDIT Note this is related to this question - I found that flipping the value of this key to true allowed me to install the app on my device)

  • Do your admins modify your web.config files?

    - by mcass20
    I'm wondering how other developers are handling source code conflicts for config files when system admins modify them in production. For example, if a system admin updates a appsettings key on the production server and then my team publishes out a project, it will overwrite that key. How do you handle config file updates in your organization?

  • Bind DataGrid to Dictionary in ASP.NET

    - by mcoolbeth
    In ASP.NET, binding a DataGrid to a list of objects is super-easy. I end up with a row for each object in the list, and any cell in a given row is bound to a property of the corresponding object. However, suppose one of the properties of my object is a dictionary, and each is expected to contain a specific key. Is there any way to bind one of my DataGridColumns to that dictionary key? Thanks.

  • MSDN Subscription Expression Studio 4 licence details

    - by pjk
    I logged into my MSDN subscription (Premium) today to download the new expression studio, and I noticed that unlike Expression 3, it requires you to enter a key, and they only provide 1. Previously I installed Expression 3 on 2 computer, my home and my work computer. So my question is, is this no longer allowed? or is it a key that can be used multiple times?

  • Reduce Multiple Errors logging in sysssislog

    - by Akshay
    Need help. I am trying to automate error notifications to be sent in mailers. For that I am querying the sysssislog table. I have pasted an "Execute SQl task" on the package event handler "On error". For testing purpose, I am deliberately trying to load duplicate keys in a table which consists of a Primary key column(so as to get an error). But instead of having just one error, "Violation of primary key constraint", SSIS records 3 in the table. PFA the screenshot as well. How can i restrict the tool to log only one error and not multiple ??? Package Structure. Package ("On error Event handler") - DFT - Oledb Source - Oledb Destination SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft SQL Server Native Client 10.0" Hresult: 0x80004005 Description: "The statement has been terminated.". An OLE DB record is available. Source: "Microsoft SQL Server Native Client 10.0" Hresult: 0x80004005 Description: "Violation of PRIMARY KEY constraint 'PK_SalesPerson_SalesPersonID'. Cannot insert duplicate key in object 'dbo.SalesPerson'.". SSIS Error Code DTS_E_INDUCEDTRANSFORMFAILUREONERROR. The "input "OLE DB Destination Input" (56)" failed because error code 0xC020907B occurred, and the error row disposition on "input "OLE DB Destination Input" (56)" specifies failure on error. An error occurred on the specified object of the specified component. There may be error messages posted before this with more information about the failure. SSIS Error Code DTS_E_PROCESSINPUTFAILED. The ProcessInput method on component "OLE DB Destination" (43) failed with error code 0xC0209029 while processing input "OLE DB Destination Input" (56). The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running. There may be error messages posted before this with more information about the failure. Please guide me. Your help is very much appreciated. Thanks

    - by Fearghal
    Need some help regarding array sorting.... I have two arrays.

Thanks guys!

  • Cracking the Playfair cipher

    - by wwrob
    I have the ciphertext and an encrypting program (with the key hardcoded in). How would I go about finding the key? Surely the availability of the encryptor must open up possibilities beyond brute-forcing it.

  • Putting update logic in your migrations

    - by Daniel Abrahamsson
    A couple of times I've been in the situation where I've wanted to refactor the design of some model and have ended up putting update logic in migrations. However, as far as I've understood, this is not good practice (especially since you are encouraged to use your schema file for deployment, and not your migrations). How do you deal with these kind of problems? To clearify what I mean, say I have a User model. Since I thought there would only be two kinds of users, namely a "normal" user and an administrator, I chose to use a simple boolean field telling whether the user was an adminstrator or not. However, after I while I figured I needed some third kind of user, perhaps a moderator or something similar. In this case I add a UserType model (and the corresponding migration), and a second migration for removing the "admin" flag from the user table. And here comes the problem. In the "add_user_type_to_users" migration I have to map the admin flag value to a user type. Additionally, in order to do this, the user types have to exist, meaning I can not use the seeds file, but rather create the user types in the migration (also considered bad practice). Here comes some fictional code representing the situation: class CreateUserTypes < ActiveRecord::Migration def self.up create_table :user_types do |t| t.string :name, :nil => false, :unique => true end #Create basic types (can not put in seed, because of future migration dependency) UserType.create!(:name => "BASIC") UserType.create!(:name => "MODERATOR") UserType.create!(:name => "ADMINISTRATOR") end def self.down drop_table :user_types end end class AddTypeIdToUsers < ActiveRecord::Migration def self.up add_column :users, :type_id, :integer #Determine type via the admin flag basic = UserType.find_by_name("BASIC") admin = UserType.find_by_name("ADMINISTRATOR") User.all.each {|u| u.update_attribute(:type_id, (u.admin?) ? admin.id : basic.id)} #Remove the admin flag remove_column :users, :admin #Add foreign key execute "alter table users add constraint fk_user_type_id foreign key (type_id) references user_types (id)" end def self.down #Re-add the admin flag add_column :users, :admin, :boolean, :default => false #Reset the admin flag (this is the problematic update code) admin = UserType.find_by_name("ADMINISTRATOR") execute "update users set admin=true where type_id=#{admin.id}" #Remove foreign key constraint execute "alter table users drop foreign key fk_user_type_id" #Drop the type_id column remove_column :users, :type_id end end As you can see there are two problematic parts. First the row creation part in the first model, which is necessary if I would like to run all migrations in a row, then the "update" part in the second migration that maps the "admin" column to the "type_id" column. Any advice?
