  • Expand Expandable Listview in android on button Click

    - by user3146145
    I am implementing expandable list view with its custom adapter. The group element needs to have 2 buttons, first as a parent group element and a button below it. My problem is, I want to expand the list view on click of the button below instead of the group element. Also, The group element onClick needs to call another activity. I can disable the expanding of the expandablelistview by `mainExpListView.setOnGroupClickListener(new OnGroupClickListener() { @Override public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) { return false; }` So my questions: Is there any way to disable the group element and get it to perform other functions (Like navigate to another activity?) How to set an onclick method on them bottom image to expand? Thank you.

  • Symfony: Pre filtering submitted values before/after validation

    - by Rob
    Hi All I've been scouring the net and i have found nothing! I am using symfonys form framework to build a simple 'Create' form. Validation is fine. However i'd like to pre-filter my submitted values, so adding ucfirst, strtoupper, and the like. I'm not sure if im missing something crucial here, but the way i see it is the only way to do this would be to create my own custom validators and utilizing the doClean method, which seems daft since i'd have hundreds of validators for each php function! Hope you guys can help, i've been crawling through source code, api's, numerous books and blogs and i haven't found a thing :( Either it's impossible, or it's really easy, i hope its the latter!

  • Exposing console apps to the web with Ruby

    - by Aaron
    I'm looking to expose an interactive command line program via JSON or another RPC style service using Ruby. I've found a couple tricks to do this, but im missing something when redirecting the output and input. One method at least on linux is to redirect the stdin and stdout to a file then read and write to that file asynchronously with file reads and writes. Another method ive been trying after googling around was to use open4. Here is the code I wrote so far, but its getting stuck after reading a few lines from standard output. require "open4" include Open4 status = popen4("./srcds_run -console -game tf +map ctf_2fort -maxplayers 6") do |pid, stdin, stdout, stderr| puts "PID #{pid}" lines="" while (line=stdout.gets) lines+=line puts line end while (line=stderr.gets) lines+=line puts line end end Any help on this or some insight would be appreciated!

  • jquery animate() problem (syntax ?)

    - by meo
    $('#somediv').stop(false, true).animate({marginLeft: '-=' + e.width() + 'px'}, options.speed, function(){ options.onNewSlide() }) e.with() returns 640 opctions.speed contains 800 options.onNewSlide() contains a a custom callback function It works fine in firefox. But i debugged it with jquery.lint because it was throwing some random error in IE. lint tells me: When I called animate(...) with your args, an error was thrown! TypeError: c.speed is not a function { message="c.speed is not a function", more...} You passed: [Object { marginLeft="-=640px"}, 800, function()] and it indicates me the line i have posted. I have checked the jquery doc, but my syntax seams ok. Do you know what i am doing wrong? PS: i use jquery 1.4.2 from the google API you can see the error here: http://meodai.ch/slider/ (i know the code is under construction, but still)

  • Mysql search design

    - by neil
    I'm designing a mysql database, and i'd like some input on an efficient way to store blog/article data for searching. Right now, I've made a separate column that stores the content to be searched - no duplicate words, no words shorter than four letters, and no words that are too common. So, essentially, it's a list of keywords from the original article. Also searched would be a list of tags, and the title field. I'm not quite sure how mysql indexes fulltext columns, so would storing the data like that be ineffective, or redundant somehow? A lot of the articles are on the same topic, so would the score be hurt by so many of the rows having similar keywords? Also, for this project, solutions like sphinx, lucene or google custom seach can't be used -- only php & mysql. Thanks!

  • Need new method for linking to native mapping from mobile web app

    - by Carter
    My mobile web apps use a map button which automatically starts the mapping features of Android and iPhone by simply linking to http://maps.google.com/maps?q=New+York. iOs 6 comes out, the links stop working, because Apple wants us to use "maps.APPLE.com". Turns out ANYTHING you send to "maps.apple.com" gets forwarded to "maps.google.com". So now I have to specially detect iOs 6 and swap out links just so Apple can forward everything back to Google anyway. Is there a clean way to open the device/native mapping app from a mobile web app that works on Android, iOs 6, and iOs pre-6, since iOs 6 nerfed it? Recently updated documentation on Apple dev site... http://developer.apple.com/library/ios/#featuredarticles/iPhoneURLScheme_Reference/Articles/MapLinks.html#//apple_ref/doc/uid/TP40007894-SW1 Both these links go to the same place http://maps.google.com/maps?q=New+York http://maps.apple.com/maps?q=New+York

  • How to enable an AdventureWorks database in a web application?

    - by salvationishere
    I am developing a C#/SQL ASP.NET web application in VS 2008. I want the users to be able to select an Adventureworks table and then an input file. The user is then able to map columns from the file with the selected table. This app works fine now in VS. But when I Browse in IIS, it doesn't show any of the tables. I think this is because currently Adventureworks connection string is integrated security (Windows authentication). If I want users to be able to select a table, do I have to change connection to SQL Server authentication? And if so, is the only way to do this to reinstall SQL Server? Or can I just reinstall Adventureworks? And if I reinstall SQL Server, do I need to reinstall VS also for this to work? This could be painful...

  • how to create a auto-incremented attribute in xcode managed object model

    - by Mausimo
    Hey, what i want to do is to make a int that will be the ID of the entity and auto increment itself whenever a new entity is added (just like a SQL identity property). Is this possible? i tried using indexed (checked on attribute) however there is no description to what indexed even does. EDIT: I am adding annotations to a map, when you click the pin the annotationview with a chevron shows up. Now when you click this button i would like to load an associated picture. However the only way i know how to link the picture to this button is to give the picture a unique id, and then set the button.tag to this id and then load based on the button.tag.

    Heading Is there a way to map an arbitrary string to a HEX COLOR code. I tried to compute the HEX number for string using string hashcode.

  • How to avoid recursion in Java SecurityManager checkConnect?

    - by Zilupe
    I'm trying to take control of a Java code base that does lots of un-documented things. I'm using a custom SecurityManager to check permission requests. Specifically, my code is checking SocketPermission checks -- checkConnect. checkConnect is called when the application tries to resolve a host name to IP address and to connect to a specific IP address. The problem is that I don't know how to properly call host name resolution (InetAddress.getAddressByName) without falling into infinite recursion, because normally checkConnect is called even when I resolve the name from inside the SecurityManager.checkConnect. I have read on the web that I have to call the address resolution from a doPrivileged block, but no idea how. P.S. Is this possible without writing any policy files?

  • MVVM Binding To Property == Null

    - by LnDCobra
    I want to show some elements when a property is not null. What is the best way of achieving this? The following is my ViewModel: class ViewModel : ViewModelBase { public Trade Trade { get { return _trade; } set { SetField(ref _trade, value, () => Trade); } } private Trade _trade; } ViewModelBase inherits INotifyPropertyChanged and contains SetField() The Following is the Trade class: public class Trade : INotifyPropertyChaged { public virtual Company Company { get { return _company; } set { SetField(ref _company, value, () => Company); } } private Company _company; ...... } This is part of my View.xaml <GroupBox Visibility="{Binding Path=Trade.Company, Converter={StaticResource boolToVisConverter}}" /> I would like this groupbox to show only if Trade.Company is not null (so when a user selects a company). Would I need to create a custom converter to check for null and return the correct visibility or is there one in .NET?

  • Spring FactoryBean and scopes working together

    - by TTar
    I'd like to use FactoryBeans and scopes together. Specifically, I'd like the object created and returned by a FactoryBean to be placed into a specified (perhaps custom) scope. The issue is that doing the following: <bean class="x.y.z.TestFactoryBean" scope="test" /> Results in the FactoryBean itself being scoped, and has somewhat unpredictable behaviour on the object created by the factory. I understand why this is; the factory itself is a first-class spring-managed bean, and has its own lifecycle. However, I can't find a way to specify that the object returned from the factory should itself be scoped. On the other hand, this does exactly what I want (as long as TestFactoryBean does NOT implement the FactoryBean interface): <bean class="x.y.z.TestFactoryBean" name="testFactory"> <bean class="x.y.z.TestBean" factory-bean="testFactory" factory-method="getObject" scope="test" /> So the real question is, how can I make Spring behave like it does for the 2nd example above, but using real FactoryBeans?

  • How to show raw_id value of a ManyToMany relation in the Django admin?

    - by luc
    Hello, I have an app using raw_id on both ForeignKeyField and ManyToManyField. The admin displays the value of the foreign key on the right of the edit box. Unfortunatey, it doesn't work with ManyToMany. I've checked the code and I think that it is the normal behavior. However I would like to know if someone has an easy tip to change this behavior? Thanks in advance Update: I've tried to subclass the ManyToManyRawIdWidget but I don't know how to say that the raw_id_fields should use my custom widget. formfield_overrides doesn't seem to work with raw_id fields

  • How to synchronize two (or n) replication processes for MS SQL databases?

    - by Yauheni Sivukha
    There are two master databases and two read-only copies updated by standard transactional replication. It is needed to map some entity from both read-only databases, lets say that A databases contains orders and B databases contains lines. The problem is that replication to one database can lag behind replication of second database, and at the moment of mapping R-databases will have inconsistent data. For example. We stored 2 orders with lines at 19:00 and 19:03. Mapping process started at 19:05, but to the moment of mapping A database replication processed all changes up to 19:03, but B database replication processed only changes up to 19:00. After mapping we will have order entity with order as of 19:03 and lines as of 19:00. The troubles are guaranteed:) In my particular case both databases have temporal model, so it is possible to fetch data for every time slice, but the problem is to identify time of latest replication. Question: How to synchronize replication processes for several databases to avoid situation described above?

  • How to link to a folder in document library from sharepoint list item?

    - by kyrisu
    Hi, Background: I have an items on the sharepoint list. I also have a corresponding folder in a document library that contains documents about this item. I want to be able to get to this folder straight from the item properties. I have tried to create a lookup column containing folder ID, but that doesn't help cause folder is not a type and it just doesn't work. Other solution would be to create link column but if I will create it staticly - after creating alternative mapping (and getting to the page from the internet for example) it won't work. (so solution posted here won't work for me). I want to create this link from sharepoint workflow. I have a custom action that can return any info about the folder I want (ID, URL etc). Question: How to link from sharepoint list item to a folder in document library?

  • Looking for a new PHP website framework

    - by Glycerine
    I built many a website, and my own 'custom' framework is just a general box of scripts cobbled together with loose ideas. I would love to progress to a framework which allows me to pass it onto the client for freedom. Someone suggested using wordpress but I'm not sure how general this can be. A current site I need to build is a fancy kitchen company, price lists, flash gallery (with backend driven pics) and well designed home. How could I bend the the will of wordpress? Alternatively, does anyone have a suggestion for an alternative. Thanks in advance guys -

  • ConcurentModificationException in Java HashMap

    Suppose I have two methods in my classes, writeToMap() and processKey() and both methods are called by multiple threads. writeToMap is a method to write something in hashmap and processKey() is used to do sth based on the keySet of HashMap. Inside processKey, I first copy the originalMap before getting the key set. new HashMap<String, Map<String,String>(originalMap).get("xx").keySet(); But I am still getting ConcurrentModificationException even though I always copy the hashmap. Whats the problem?

  • Oauth2 External Browser Request - App Launches, Credentials received, Browser Not Updated

    - by Michael Drozdowski
    I'm using an external browser request to authenticate myself with the SoundCloudAPI in OSX. My app launches, and has a button that opens an external browser window to authenticate against SoundCloud. When I click "connect" in the new window, I get a "External Protocol Request" that is consistent with my custom launch URI scheme. Clicking this loads the app, and it gets the correct credentials. The trouble is, the browser window never changes - it simply says that it's connecting forever. There is no "connection confirmed" alert coming from SoundCloud. I know I'm logged in because I can make the correct calls to the API to get things such as my username. Why isn't the browser confirming the connection or dismissing? The same thing happens if I load the authentication in an internal WebView in the app.

  • Return result of block passed to #scan during regex

    - by Oli
    I've searched and not been able to find the right way of doing what I'm trying to. I read a file line by line and want to create a new object from a regex on each line. I'm not using an XML parser because the data is not well formed and listed below is all I need to get from each line. I can't seem to get scan to return the result of the block. It just returns the original string. I have temporarily gotten around it by creating this temp variable, but I'm sure there is a better way. enum = File.foreach(filename) enum.map do |line| temp = nil line.scan(/<cab id="(\w+)" updates="(\d+)"/) { |a,b| temp = Cab.new(a,b) } temp end Thanks for any help.

  • Passing around objects to network packet handlers ?

    - by xeross
    Hey, I've been writing a networking server for a while now in C++ and have come to the stage to start looking for a way to properly and easily handle all packets. I am so far that I can figure out what kind of packet it is, but now I need to figure out how to get the needed data to the handler functions. I had the following in mind: Have a map of function pointers with the opcode as key and the function pointer as value Have all these functions have 2 arguments, packet and ObjectAccessor ObjectAccessor class contains various functions to fetch various items such as users and alike Perhaps pass the user's guid too so we can fetch it from the objectaccessor I'd like to know the various implementations others have come up with, so please comment on this idea and reply with your own implementations. Thanks, Xeross

  • Anonymous iterator blocks in Clojure?

    - by Checkers
    I am using clojure.contrib.sql to fetch some records from an SQLite database. (defn read-all-foo [] (with-connection *db* (with-query-results res ["select * from foo"] (into [] res)))) Now, I don't really want to realize the whole sequence before returning from the function (i.e. I want to keep it lazy), but if I return res directly or wrap it some kind of lazy wrapper (for example I want to make a certain map transformation on result sequence), SQL-related bindings will be reset and connection will be closed after I return, so realizing the sequence will throw an exception. How can I enclose the whole function in a closure and return a kind of anonymous iterator block (like yield in C# or Python)? Or is there another way to return a lazy sequence from this function?

  • Action method expected parameter named Id and nothing otherwise

    The Error The parameters dictionary contains a null entry for parameter 'UserId' of non-nullable type 'System.Int64' for method 'System.Web.Mvc.ActionResult Predict(Int64)' in 'sportingbiz.Controllers.PredictionController'. An optional parameter must be a reference type, a nullable type, or be declared as an optional parameter. Parameter name: parameters This does not work. Throws the error mentioned above http://mysite/User/Profile/15 This works http://mysite/User/Profile/?UserID=15 The Controller Action public ActionResult Profile(long UserID) { } When I changed the parameter name to Id it works. I think it's because Id was specified in the route collection (Global.asax). Is it possible to tell MVC that UserId should map to Id without changing it in the Global.asax
