  • How do I fix this warning in my mx:request tag?

    - by invertedSpear
    I'm running an HTTPService with the following request: <mx:request xmlns=""> <view>{myViewStack.selectedChild.name}</view> </mx:request> The idea being to pass which child is selected on the viewstack to the php page, and then get that back so I can run some logic based on which child of the viewstack was selected at the time. Everything seems to work, but I get the following warning: Data binding will not be able to detect assignments to "name". This doesn't seem to be causing any trouble, but I know warnings usually mean that I am not following the best practice. How can I fix this? I don't really need this item to be bound, because the name will never change at runtime, but I don't know how else to include it in the request.

  • MySQL: Order by time (MM:SS)?

    - by Shpigford
    I'm currently storing various metadata about videos and one of those bits of data is the length of a video. So if a video is 10 minutes 35 seconds long, it's saved as "10:35" in the database. But what I'd like to do is retrieve a listing of videos by length (longest first, shortest last). The problem I'm having is that if a video is "2:56", it's coming up as longest because the number 2 is more than the number 1 in. So, how can I order data based on that length field so that "10:35" is recognized as being longer than "2:56" (as per my example)?

  • Joomla 2.5 disable and remove Smart Cache

    - by WooDzu
    I am maintaining a Joomla 2.5 based magazine website with 3-4 new, long articles every day. Smart Search was enabled by default and now I've got a few "finder" tables full of indexed phrases and therms. I wonder if there are any disadvantages if I'd: Disable the Smart Search plugin Remove these 'finder' tables completely Aha, we're using a Search field, which works fine, but I'm not sure what's going to happen if I disable the plugin and remove these tables. Will it then search for phrases in content Joomla tables or simply break w/o missing 'finder' tables Has anyone tried this before?

  • How do I view the parameters of currently running procs in SQL Server 2008

    - by Pez
    I am trying to troubleshoot an issue that is popping up on our new SQL Server. While viewing the running processes (sp_who2) I can't tell what parameters a proc was started with. I can find the name of the proc using: DBCC INPUTBUFFER (spid) I can even find some additional info, but I can't see a way to show the parameters. (http://sqlserverpedia.com/blog/sql-server-bloggers/sql-server-%E2%80%93-get-last-running-query-based-on-spid/) I know I can see the parameters if I do a trace, but that doesn't help in this case.

  • Response Time is different for mulitiple execution of the application with the same request Performa

    - by sivananda
    My java application functionality is to provide reference data (basically loads lots of data from xml files into hashmap) and hence we request for one such data from the hashmap based on a id and we have such multiple has map for different set of business data. The problem is that when i tried executing the java application for the same request multiple times, the response times are different like 31ms, 48ms, 72ms, 120ms, 63ms etc. hence there is a considerable gap between the min and max time taken for the execution to complete. Ideally, i would expect the response times to be like, 63ms, 65ms, 61ms, 70ms, 61ms, but in my case the variation of the response time for the same request is varying hugely. I had used a opensource profile to understand if there is any extra execution of the methods or memory leak, but as per my understanding there was no problem. Please let me know what could be the reasons and how can i address this problem.

  • How can I debug a Perl program that suddenly exits?

    - by taw
    I have Perl program based on IO::Async, and it sometimes just exits after a few hours/days without printing any error message whatsoever. There's nothing in dmesg or /var/log either. STDOUT/STDERR are both autoflush(1) so data shouldn't be lost in buffers. It doesn't actually exit from IO::Async::Loop->loop_forever - print I put there just to make sure of that never gets triggered. Now one way would be to keep peppering the program with more and more prints and hope one of them gives me some clue. Is there better way to get information what was going on in a program that made it exit/silently crash?

  • JSF templating beginner's question.

    - by Nitesh Panchal

I mean say suppose i have a menu in template, and based on roles menu changes. If the Admin logs in, he will get to show more options and if general user logs in he will get to see less options. Now i have a managed bean for my "real" page(not template). How do i use this managed bean to toggle my control in template on and Off?

  • C++11 initialize array with uniform value in constexpr function

    - by marack
    I have a class template which builds a simple array based on the template parameters as one of its members. I need to be able to initialize every element in the array to a single value in one of the constructors. Unfortunately this constructor must be constexpr. The relevant part boils down to: template <typename T, size_t N> class foo { T data[N]; constexpr foo(T val) { // initialize data with N copies of val } }; Using std::fill or a loop is incompatible with the constexpr requirement. Initializing with : data{val} only sets the first element of the array and zero-initializes the remainder. How can this be achieved? I feel like there should be a solution with variadic templates and tuples etc...

  • What Java tools/apis to use for decrypting/encrypting

    - by Java_bear
    I am trying to decrypt (and later encrypt) an email message (ebXML). The message contains a Signature element that contains child elements to specify the SignedInfo, SignatureValue and KeyInfo. Also, the message contains an encrypted attachment. Question: What Java tools/apis should be used for decrypting? I would like to find some tool/api that would (automagically) instantiate objects based on whatever is included with the Signature element, so that the data (message) could be easily validated. And the other way around: Creating objects (specifying methods, signature value and keyinfo) and then outputting the xml to go into the message.

  • What GC parameters is a JVM running with?

    - by skaffman
    I'm still investigating issues I have with GC tuning (see prior question), which involves lots of reading and experimentation. Sun Java5+ JVMs attempt to automatically select the optimal GC strategy and parameters based on their environment, which is great, but I can't figure out how to query the running JVM to find out what those parameters are. Ideally, I'd like to see what values of the various GC-related -XX options are being used, as selected automatically by the VM. If I had that, I could have a baseline to begin tweaking. Anyone know to recover these values from a running VM?

  • How to deal with time zones in a Rails app with events...

    - by Tony
    I have a Rails app for bands. Bands can import their shows which all occur in different time zones. It seems like a ton of work to store these events in UTC. I would have to figure out the time zone for any show created and then convert back to the show's local time zone when displaying to the user. Is there a simple plugin to get a UTC offset based on geolocation? That would probably help, but does anyone see any major reasons why I should store in UTC here? I understand storing timestamps in UTC is probably a good idea...but band event times?

  • Android: Maps - Best way to provide 'search for location' feature?

    - by r3mo
    Hello all, I've got an android app that uses a map activity and serves up content based on map location. I'm looking for a way to allow the user to search for a location by name (anything from 'New York' to 'Eiffel Tower') - e.g. have a text input field into which they could type 'Rome' - after pressing a button, the user would be brought to the coordinates of Rome on the map. What would be the best way to go about this? I've looked into the google geocoding api (http://code.google.com/apis/maps/documentation/geocoding/), but it has limitations of 2,500 geolocation requests per day - I'm presuming this is per API key? Or is it per user/source IP? 2,500 requests for one android app woudln't last long. Ideally, I would be able to search for English and foreign names of countries. Thanks in advance! r3mo

  • Centralized way of organizing urls in Jersey?

    - by drozzy
    Forgive me if I am asking an obvious question (maybe I missed it in the docs somewhere?) but has anyone found a good way to organize their URLs in Jersey Java framework? I mean organizing them centrally in your Java source code, so that you can be sure there are not two classes that refer to the same Url. For example django has a really nice regex-based matching. I was thinking of doing something like an enum: enum Urls{ CARS ("cars"), CAR_INFO ("car", "{info}"); public Urls(String path, String args) ... } but you can imagine that gets out of hand pretty quickly if you have urls like: cars/1/wheels/3 where you need multiple path-ids interleaved with one another... Any tips?

  • What types of conditions can be used for conditional compilation in C++?

    - by user1002288
    This is an exam question for C++: Which of the following statements accurately describe the condition that can be used for conditional compilation in C++? A. The condition can depend on the value of environment variables. B. The condition can depend on the value of any const variables. C. The condition can depend on the value of program variables. D. The condition can use the sizeof() operator to make decision about compiler-dependent operations based on the size of standard data type. E. The condition must evaluate to either a 0 or 1 during preprocessing. I think the answer is E. Is this correct?

  • Join data from two Lists into one object

    - by Petr Mensik
    I ran into following situation and I am wondering about best solution. Let's say I have List<Object1> and List<Object2>, these lists are result of two separated queries. Both of them have the same size and there is relationship 1:1 between elements in the lists based on ID. I know that best solution would be fetching data in one DB query but that's possible right now. So my question is, what is the best way to join these lists into let's say List<Object3>?

  • Google Maps API - load the US

    - by hjk
    I am new to google maps api. I'd like suggestions on achieving the following functionality: whenever the page loads, the map will load centered around the US. Imagine a box around the US with given lat/longs specifying the minimum and maximum boundaries. I need the map to load at the appropriate zoom (and zoom needs to be disabled) such that this box composes the entire map. Basically, I'm wondering if there is a function that loads the map based on lat/long boundaries (or some way to acheive this), rather then loading the map given a zoom level.

  • jQuery autocomplete that retrieves items from a database

    - by Ankur
    I want to provide autocomplete for users when they are filling in a text box. The values for the autocomplete should come from a mysql database that I use with the application. Can you please recommend a plugin or two that would be best suited to this. I can see that there are a number of options out there. But I was hoping that based on the answers it would be clear that one or two plugins are considered to be the better ones, and I would only have to choose from those. Thanks,

  • Save objects to a database?

    - by Eric
    So far in my .Net coding adventures I've only had a need to save information to files. So I've used XmlSerializer and DataContractSerializer to serialize attributed classes to XML files. My next project, however, requires that I save and retrieve information from a SQL server database. I'm wondering what my options are for doing this. The current version of the app, which was not created by me, uses a lot of hard coded SQL commands. But now I'm trying to avoid doing anything where I have to read or write individual fields to or from the database or objects. I especially want to avoid a lot of hard coded SQL in my code. I like how the serializer classes just figure out how to read and write XML files based on the attributes and or public properties of the class. Is there something similar for a database rather then XML?

  • Lightweight open source CMS - current situation

    - by patrikas
    Hello, It happened that I need to pick up PHP based open source CMS. I did a small research and found many candidates. CMS made simple seems to be right choice, but I am not sure what's the current state, I know it was widely used time ago. I need it to be fully compliant with web standarts, lightweight (especially interface). It needs to be as simple as possible - basically just style and page content editing (news, maybe some image gallery) is enough. Sure content and style have to be separated from each other since content will be edited by non-programmer. One of the main goals is SEO so I'd like it to have friendly URLs. I think CMSes like Joomla, Drupal and Wordpress are too big for this project. Are there any recommendations ?

  • How can I find out how much memory an object of a C++ class consumes?

    - by Shadow
    Hi, I am developing a Graph-class, based on boost-graph-library. A Graph-object contains a boost-graph, so to say an adjacency_list, and a map. When monitoring the total memory usage of my program, it consumes quite a lot (checked with pmap). Now, I would like to know, how much of the memory is exactly consumed by a filled object of this Graph-class? With filled I mean when the adjacency_list is full of vertices and edges. I found out, that using sizeof() doesn't bring me far. Using valgrind is also not an alternative as there is quite some memory allocation done previously and this makes the usage of valgrind impractical for this purpose. I'm also not interested in what other parts of the program cost in memory, I want to focus on one single object. Thank you.

  • Passing report values to a query

    - by Beavis
    I'm a novice with Microsoft Access as my background is mostly .NET. I'm sure what I'm trying to accomplish is dead simple but I need some direction. I have a report and a query. The query returns a single numeric value based on a single numeric criteria. Select total from table where id = [topic] I have placed a text box on my report so I can feed the id to this query and in return get the total. It seems like DLookUp is what I want but no matter how I construct it, I get an "#Error" in the text box when I run the report. Currently my DLookUp looks like this (I just hard-coded now for simplicity): =DLookUp("[total]","myquery","[topic] = 3") How can I pass a value from a field on my report to a query so I can return the query's single numeric value? Thanks.

  • What do I need to learn to make a website that can make a text file?

    - by lala
    I want to make a website, but all I know is basic HTML and CSS. On this website, I want the user to input in multiple text fields (sort of like they take a quiz) and then the program will make a text file based on the user input which the user can download. I want it to work backwards, too, so that the text file is the input. What do I need to learn to make a website to do this? Will javascript do the trick? I'm a beginning to intermediate programmer, mainly with java and I've learned some C# recently. I thought I could learn ASP.Net for this, but it turns out my hosting doesn't support it.

  • Sharepoint 2010 search: How to modify search query before submit (programmatically?)

    - by palgo
    Hi, I'm making a custom search box Web Part, similar to the OOTB Web Part from SharePoint (SearchBoxEx class). I'm interested in modifying the search query with additional text before it is submitted, based on a custom checkbox added on the Web Part. Any help on how I can achieve this? UPDATE: I've used the AppendToQuery and AppQueryTerms properties, but this will rewrite the text in the search box as well. I'm interested in passing the values "in the background", maybe as an extra parameter. Point is that the query modification should happen without the user seeing it explicitly.
