  • Easiest way to pass a javascript array or its values to a servlet using jQuery's ajax() function

    - by Ankur
    I have a Javascript array. I want to pass it's data to a servlet using the ajax() method of jQuery. What is the easiest way to do this. The index values i.e. the i in array[i] are not in order, they are numbers that have meaning themselves, hence I cannot simply loop through and create a GET queryString, or so I believe. Maybe I should be converting the JavaScript array to a JSON Object and sending that to the server ?? I am stumped on this one.

  • Is there any way to create a dynamic list of strings (based on language) in XAML?

    - by Xin
    Just wondering if it is possible to dynamically create a list of strings in XAML based on language/culture? Say if user logs in as an English user it shows Client Name, Order Number... and if user logs in as a Polish user it shows Nazwa klienta, Numer zamówienia instead? I only know the hardcoded one like below: <System_Collections_Generic:List`1 x:Key="columnNameList"> <System:String>Client Name</System:String> <System:String>Order Number</System:String> <System:String>Date</System:String> </System_Collections_Generic:List`1>

  • Can you automatically create a mysqldump file that doesn't enforce foreign key constraints?

    - by Tai Squared
    When I run a mysqldump command on my database and then try to import it, it fails as it attempts to create the tables alphabetically, even though they may have a foreign key that references a table later in the file. There doesn't appear to be anything in the documentation and I've found answers like this that say to update the file after it's created to include: set FOREIGN_KEY_CHECKS = 0; ...original mysqldump file contents... set FOREIGN_KEY_CHECKS = 1; Is there no way to automatically set those lines or export the tables in the necessary order (without having to manually specify all table names as that can be tedious and error prone)? I could wrap those lines in a script, but was wondering if there is an easy way to ensure I can dump a file and then import it without manually updating it.

  • how to create a particle system on iphone and retain the created particles?

    - by lukya
    Hi all, I need to create a particle system and retain the created particles. I need to shake / move the created particles with the iphone accelerometer. Also, the number of particles needs to be very high (I need to show sand!). I do not have any OpenGLES programming experience. After initial search, I found Cocos2D can be used for particle generation. But there is no way of retaining the particles in the CCParticle system. As a work around, I tried creating many sprites at the end of particle generation and shown them as particles. But moving few number of sprites with accelerometer drops the frame rate considerably. Please suggest how this can be achieved and whether I should look for some other framework or if some kind of similar demo code is available. Thanks, Swapnil

  • I have a bunch of divs floated left, lined up in columns with different heights. They dont create a

    - by Roeland
    Hey guys, I am trying to create a grid like system with div's with content floated left. The problem is that the height of each div is not static since the content is different in each one. Since the height is different.. things get outta whack if one is taller then another in one row. Is there some sort of css way or js (prefer javascript) way to get around this. I really want to avoid setting large heights on the divs to get them to line up. You can see the example here: http://www.foreclosurejournalinc.com/index.php?option=com_hotproperty&view=type&id=1

  • Accessing Members of Containing Objects from Contained Objects.

    - by Bunkai.Satori
    If I have several levels of object containment (one object defines and instantiates another object which define and instantiate another object..), is it possible to get access to upper, containing - object variables and functions, please? Example: class CObjectOne { public: CObjectOne::CObjectOne() { Create(); }; void Create(); std::vector<ObjectTwo>vObejctsTwo; int nVariableOne; } bool CObjectOne::Create() { CObjectTwo ObjectTwo(this); vObjectsTwo.push_back(ObjectTwo); } class CObjectTwo { public: CObjectTwo::CObjectTwo(CObjectOne* pObject) { pObjectOne = pObject; Create(); }; void Create(); CObjectOne* GetObjectOne(){return pObjectOne;}; std::vector<CObjectTrhee>vObjectsTrhee; CObjectOne* pObjectOne; int nVariableTwo; } bool CObjectTwo::Create() { CObjectThree ObjectThree(this); vObjectsThree.push_back(ObjectThree); } class CObjectThree { public: CObjectThree::CObjectThree(CObjectTwo* pObject) { pObjectTwo = pObject; Create(); }; void Create(); CObjectTwo* GetObjectTwo(){return pObjectTwo;}; std::vector<CObjectsFour>vObjectsFour; CObjectTwo* pObjectTwo; int nVariableThree; } bool CObjectThree::Create() { CObjectFour ObjectFour(this); vObjectsFour.push_back(ObjectFour); } main() { CObjectOne myObject1; } Say, that from within CObjectThree I need to access nVariableOne in CObjectOne. I would like to do it as follows: int nValue = vObjectThree[index].GetObjectTwo()->GetObjectOne()->nVariable1; However, after compiling and running my application, I get Memory Access Violation error. What is wrong with the code above(it is example, and might contain spelling mistakes)? Do I have to create the objects dynamically instead of statically? Is there any other way how to achieve variables stored in containing objects from withing contained objects?

  • How to create a RESTful web service in asp.net?

    - by jonhobbs
    Hi Guys, I simply want to create a fairly basic REST service, so that I can expose some of the data in my asp.net/SQL server application to the outside works, like this..... http://domain.com/api/offices - would return an xml set of office locations. http://domain.com/api/offices/15 - would return all the details of office 15. It's all fairly standard stuff (including basic authentication) but there seem to be several ways to achieve this using Microsoft technologies and I don't really know where to start. These seem to be the options... 1) WCF 2) ASP.NET MVC 3) ADO.NET Data Services 4) Rest Starter Kit project templates? Which of these is the easiest and most "up-to-date" solution to creating a web service?

  • would like to create a .php file that reads an .xml file and delivers xml output from the .xml file

    - by Andy
    I know it sounds weird but I need it for a workaround. So some link in an ActionScript links for a .php file. As I am unable to edit this link in the AS I need some workaround. I have the xml and the .php file needs to output that exact xml code. How can this be done. Ultimately I would like to create a .php script that outputs xml. Where can I find instructions on how to do this? thanks!

  • How do I create a Windows 7 USB installer with preinstalled software?

    - by Marcel
    I was wondering if it was possible to make a bootlable image of a Windows 7 Pro OEM Installation CD that I have and put it on an USB stick for faster/easier installation. I am asking because we have a couple of PC´s where I´d have to install the OS using the same key (MAK). Also is it possible to kind of populate that image with software that would have to be installed anyways on all machines (like Chrome, Outlook, etc)? It would be really helpful to just install a Windows 7 image with customized software already installed. I would just make an image of an OS and use that, but the hardware of the machines differ.

  • Create access point (uap0) on debian 7(arm) - not found?

    - by ethrbunny
    I'm working with a fanless PC that has an ARM chipset, 2 eth plugs and a wifi card (among other things). If I install debian 6 on it all three network interfaces are available at boot time. Today I tried to install debian 7 and had numerous errors indicating that the wireless card isn't supported. uap0: error fetching interface information: Device not found SIOCSIFADDR: No such device uap0: ERROR while getting interface flags: No such device uap0: ERROR while getting interface flags: No such device No such device ERR:UAPHOSTCMD is not supported by uap0 ERR:Command sending failed! No such device ERR:UAPHOSTCMD is not supported by uap0 ERR:Command sending failed! I've tried comparing the kernel module list to the working system but there are too many other differences to make something obvious enough (to me) stand out. How would I get started debugging this problem?

  • Server side form validation and POST data

    - by tomcritchlow
    Hi, I have a user input form here: http://www.7bks.com/create (Google login required) When you first create a list you are asked to create a public username. Unfortuantely currently there is no constraint to make this unique. I'm working on the code to enforce unique usernames at the moment and would like to know the best way to do it. Tech details: appengine, python, webapp framework What I'm planning is something like this: first the /create form posts the data to /inputlist/ (this is the same as currently happens) /inputlist/ queries the datastore for the given username. If it already exists then redirect back to /create display the /create page with all the info previously but with an additional error message of "this username is already taken" My question is: Is this the best way of handling server side validation? What's the best way of storing the list details while I verify and modify the username? As I see it I have 3 options to store the list details but I'm not sure which is "best": Store the list details in the session cookie (I am using GAEsessions for cookies) Define a separate POST class for /create and post the list data back from /inputlist/ to the /create page (currently /create only has a GET class) Store the list in the datastore, even though the username is non-unique. Thank you very much for your help :) I'm pretty new to python and coding in general so if I've missed something obvious my apologies. Tom PS - I'm sure I can eventually figure it out but I can't find any documentation on POSTing data using the webapp appengine framework which I'd need in order to do solution 2 above :s maybe you could point me in the right direction for that too? Thanks! PPS - It's a little out of date now but you can see roughly how the /create and /inputlist/ code works at the moment here: 7bks.com Gist

  • Is there a .def file equivalent on Linux for controlling exported function names in a shared library

    - by morpheous
    I am building a shared library on Ubuntu 9.10. I want to export only a subset of my functions from the library. On the Windows platform, this would be done using a module definition (.def) file which would contain a list of the external and internal names of the functions exported from the library. I have the following questions: How can I restrict the exported functions of a shared library to those I want (i.e. a .def file equivalent) Using .def files as an example, you can give a function an external name that is different from its internal name (useful for prevent name collisions and also redecorating mangled names etc) On windows I can use the EXPORT command (IIRC) to check the list of exported functions and addresses, what is the equivalent way to do this on Linux?

  • Do I have to create a static library to test my application?

    - by Christopher Gateley
    I'm just getting started with TDD and am curious as to what approaches others take to run their tests. For reference, I am using the google testing framework, but I believe the question is applicable to most other testing frameworks and to languages other than C/C++. My general approach so far has been to do either one of three things: Write the majority of the application in a static library, then create two executables. One executable is the application itself, while the other is the test runner with all of the tests. Both link to the static library. Embed the testing code directly into the application itself, and enable or disable the testing code using compiler flags. This is probably the best approach I've used so far, but clutters up the code a bit. Embed the testing code directly into the application itself, and, given certain command-line switches either run the application itself or run the tests embedded in the application. None of these solutions are particularly elegant... How do you do it?

  • is it legal to use fontsquirrel.com to create a @font-face kit for a font I have been given?

    - by ongoingworlds
    fontsquirrel.com allows you to upload a font and create a @font-face kit which you can apply to your website and use to display fonts which will display cross-browser (even in IE6!). But what I want to know is, is this legal? I've been supplied the font "Lubalin Graph Std" and told to use this for headers on the website I'm creating. I can upload the font file to fontsquirrel.com and use this to display headers in this font across the website - but I'm worried we'll get into trouble for doing this. What should I do?

  • How do I create a downscaled copy of an FBO in OpenGL?

    - by Jasper Bekkers
    Hi, In order to speed up some post-processing shaders I'm using, I need to perform these operations on a framebuffer that is smaller in size than the actual window (about 1/4th or more). Most of the effects I want to optimize are simple blurring operations that could be replaced (for a large part) by smaller kernel and bilinear filtering. Thus, I need to create a copy of the current FBO into another one. However, I couldn't find anything, that works, on how to do this. I've tried using glBlitframebufferEXT and rendering a fullscreen quad into the other framebuffer, but both paths result in a black texture as output. How do I go about solving this problem?

  • How do i create a view that can filter unique titles from a checkbox?

    - by buws
    I'm currently creating a view in Drupal that contains a number of fields. What I want to do is to create an exposed filter that is able to filter duplicate titles. The filter would be a checkbox. This is an example of the list NAME TIME RACE DISTANCE John Doe 2.07.54 Boston Marathon 42km Jane Boss 2.15.21 Boston Marathon 42km John Doe 2.02.22 Boston Marathon 42km Jane Boss 2.15.44 Boston Marathon 42km What I want to have is an exposed filter that only shows one unique NAME and sorts it by its best time. The resulting list would look as follows: NAME TIME RACE DISTANCE Jane Boss 2.15.21 Boston Marathon 42km John Doe 2.02.22 Boston Marathon 42km Any help is appreciated!

  • How do you map a solo press of a modifier key to its own function or mapping on Windows?

    - by Conrad.Dean
    Today on hacker news there was a clever article on custom shortcut keys. The author talks about a technique for remapping a modifier key such as CTRL to ESC if CTRL were pressed without a modifier. This is useful in vim because of how often you need to press ESC. Another technique he describes is mapping the open parenthesis, ( to the left shift key, and ) to the right shift key. If another key is pressed when shift is held down, the shift key behaves normally. The author describes the software he uses on OSX, but is there a way to do this on Windows? I've heard of AutoHotKey but it seems to only fire macros when simple keys are pressed, rather than the conditional state switch that this would require.

  • Is Django's manage.py syncdb or South used to create the test database?

    - by Thierry Lam
    With Django 1.1.1 and South 0.62, running a test from the CLI usually have the following output: Creating table some_model Installing index for my_app.SomeModel model . ----- Ran 1 test in 1s OK After upgrading to South 0.7, the output is invoking South's migration: Creating table some_model Installing index for my_app.SomeModel model Migrating... Running migrations for my_app: - Migrating forwards to 0001_initial > my_app:0001_initial - Loading initial data for my_app Migrated: - my_app . ----- Ran 1 test in 1s OK To create the test DB, has the test always used South migration in the past(before South 0.7) even if the output is not explicitly being shown?

  • How to create a view of table that contains a timestamp column?

    - by Matt Faus
    This question is an extension of a previous one I have asked. I have a table (2014_05_31_transformed.Video) with a schema that looks like this. I have put up the JSON returned by the BigQuery API describing it's schema in this gist. I am trying to create a view against this table with an API call that looks like this: { 'view': { 'query': u 'SELECT deleted_mod_time FROM [2014_05_31_transformed.Video]' }, 'tableReference': { 'datasetId': 'latest_transformed', 'tableId': u 'Video', 'projectId': 'redacted' } } But, the BigQuery API is returning this error: HttpError: https://www.googleapis.com/bigquery/v2/projects/124072386181/datasets/latest_transformed/tables?alt=json returned "Invalid field name "deleted_mod_time.usec". Fields must contain only letters, numbers, and underscores, start with a letter or underscore, and be at most 128 characters long." The schema that the BigQuery API does not make any distinction between a TIMESTAMP data type and a regular nullable INTEGER data type, so I can't think of a way to programmatically correct this problem. Is there anything I can do, or is this a bug with BigQuery's view implementation?

    How to add sort function for the table via ajax in ASP.NET MVC?What is the best practice. If not use Ajax, it maybe much easier, just return View, but if use AJAX, what data structure should return?I just use Json to return the data, but i found each JSON data model return to the client browser, the JS have to use different code to parse it, remove the originally table rows, add the new data rows(because the column is different) etc. It make me crazy, is there any better way to do that? Thank you for any advice.

  • How to create a tree with filtered nodes from drupal taxonomy.

    - by sprugman
    I'm trying to create a menu tree in drupal like this: - term 1 node 1 node 2 - sub-term 1 node 3 node 4 + sub-term 2 - sub-term 3 node 5 - sub-sub-term 1 node 6 + term 2 etc. (Sub-term 2 and term 2 are toggled closed.) Some requirements: Output this using something like JQuery Menu to get an interactive tree Filter the nodes by cck type Filter the nodes by cck field Only have terms with nodes or other active terms in them show up Mark the current node as such, and automatically open the tree to that point Do I have to write this myself, or are there a combination of modules that can do it? I've got Advanced Taxonomy Blocks, which is pretty close, but it doesn't list the nodes.
