  • Access uploaded file in JSON encoded data

    - by okello
    I've encoded my form data into JSON. This has been achieved by the following ExtJS store configuration: Ext.define('XXX.store.Registration', { extend: 'Ext.data.Store', model: 'XXX.model.Registration', autoLoad: true, pageSize: 15, autoLoad: { start: 0, limit: 15 }, proxy: { type: 'ajax', api: { create: './server/registration/create.php', read: './server/registration/get.php', update: './server/registration/update.php', destroy: './server/registration/destroy.php' }, reader: { type: 'json', root: 'registrations', successProperty: 'success' }, writer: { type: 'json', writeAllFields: true, encode: true, root: 'registrations' } } }); My server side code has been implemented in PHP. I can access the encoded form fields by using the field name as a key, as exemplified below: $reg = $_REQUEST['registrations']; $data = json_decode(stripslashes($reg)); $registerNum = $data->registerNum; $folioNum = $data->folioNum; One of the fields in my form is a fileuploadfield. How can I access the uploaded file from the uploaded JSON. Any assistance will be highly appreciated.

  • handing data returned from jquery get request

    - by ian
    I have a simple jquery script as follows: $('a').click(function() { //get the id of the song we want to play var song_id = $(this).attr("id"); //do a get request to get the information about the song $.get("http://www.site.com/v4/ajax/get_song_info.php", { id: song_id, }, function(data) { alert("Data Loaded: " + data); }); //alert( song_id ); }); I have gotten it to work and it returns several bits of data 'artist' 'title' 'song duration' and so on. How do I process my 'data' so I can then update my page with each bit. In this case I want to set a series of '' to hold each of the values returned. Thanks.

  • Android sql creating database once

    - by semajhan
    One thing i'm not understanding is how to create the database and data just once in an android application. I extend SQLiteOpenHelper and use a DataHelper class that to manipulate data. Now, I have addEvent() and updateEvent() within the DataHelper class. I create an instance of DataHelper in my Activity and addEvent() a couple of times to insert data. Well, now I don't know how to just do that once. If I restart the app, its just going to "addEvent()" again and so the data is being reset every time. Sorry for the probably really REALLY noob question. The only solution I found was not using the DataHelper class and just adding data "manually" within the onCreate() method in SQLiteOpenHelper.

  • MVC + Repository Pattern - Still depends on Data Model?

    - by Jack
    I've started a project for school in which I am using ASP.NET MVC 2 + LINQ2SQL, and a business layer so my UI doesnt interact with the DB directly. My question is this: In my MVC project, when bringing up views and passing around data, I still have to include my Data project for access to the classes in my Linq2Sql project. Is this correct? Example: Controller: ClassesRepository cr = new ClassesRepository(); // this is from my Business project Class classToEdit = cr.GetByClassId(id); // "Class" is from my data project I still have to reference the Class class in my linq2sql data project - shouldn't my UI be completely independent of my data layer? Or maybe I'm going about this all wrong.

  • Shared data in an ASP.NET application

    - by Barguast
    I have a basic ASP.NET application which is used to request data which is stored on disk. This is loaded from files and sent as the response. I want to be able to store the data loaded from these files in memory to reduce the number of reads from disk. All of the requests will be asking for the same data, so it makes sense to have a single cache of in-memory data which is accessible to all requests. What is the best way to create a single accessible object instance which I can use to store and access this cached data? I've looked into HttpApplication, but apparently a new instance of this is created for parallel requests and so it doesn't fit my needs.

  • Sharing information between applications

    - by Zé Carlos
    My question is very simple to expose: I have a few aplications that share data between then. I need a way to support that data sharing (cross several computers) and when one aplication changes data, others should be notified about that. My question is about what tecnologies could be usefull to me. The solution i realise at this moment is to have a database to share data and an external publish-subscribe system (like http://pubsub.codeplex.com/) to notify all applications when the data is changed. But i belive that could exist some helpfull solutions. Do you know any of then? Thanks.

  • Micro Controller Serial Data identification or classification

    - by Posiedon
    I have a x51 family micro controller (P89V51RD2). I'm going to send some data from computer using serial port. The data i'll be sending are Character 'S' Character 'R' and a 2 digit integer. Upon receiving the data, I will be calling separate functions. I used if(chr=='S') and elseif(chr=='R')for character data. The main problem lies with identifying the 2 digit number sent. Any other data other than the above three mentioned will be discarded. Any ideas for identifying two digit integer ??

    - by Fruxelot
    i'm building a wordpress webpage based on the Skeleton Wordpress theme. I have 2 posts showing on a page and each of these posts have custom fields values (meta data). Im using the shortcode from the skeleton theme to get a post-feed from a specific category and in that loop i have inserted this tag that displays the custom fields data <?php the_meta(); ?> I am getting the data - but the problem is, the data is shown on TOP of the page instead of inside the in the post. What could've ive possibly done wrong? or is it something with skeleton i am doing wrong? Webpage : http://visbyfangelse.se.preview.binero.se/rum-priser-preview/ as you can see two posts are shown - and the meta data is shown on the top of the page. Code to the loop : http://pastebin.com/mRQY5GNz As you can see i want the meta displayed in the div which i assigned this class to "my_room_meta".

  • How to reduce latency of data sent through a REST api

    - by Sid
    I have an application which obtains data in JSON format from one of our other servers. The problem I am facing is, there is is significant delay when when requesting for this information. Since a lot of data is passed (approx 1000 records per request where each record is pretty huge) is there a way that compression would help reducing the speed. If so which compression scheme would you recommend. I read on another thread that they pattern of data also matters a lot on they type of compression that needs to be used. The pattern of data is consistent and resembles the following :desc=>some_description :url=>some_url :content=>some_content :score=>some_score :more_attributes=>more_data Can someone recommend a solution to how I could reduce this delay. They delay is approx 6-8 seconds. I'm using Ruby on Rails to develop this application and the server providing the data uses Python for the most part.

  • web service data type (contract)

    - by cyberguest
    hi, i have a general design question. we have a fairly big data model that represents an clinical object, the object itself has 200+ child attributes in the hierarchy. and we have a SetObject operation, and a GetObject operation. my question is, best practice wise, would it make sense to use that single data model in both operations or different data model for each? Because the Get operation will return much more details than what's needed for Set. an example of what i mean: the data model has say ProviderId, and ProviderName attributes, in the Get operation, both the ProviderId, and ProviderName would need to be returned. However, in the Set operation, only the ProviderId is needed, and ProviderName is ignored by the service since system has that information already. In this case, if the Get and Set operations use the same data model, the ProviderName is exposed even for Set operation, does that confuse the consuming developer?

  • Copy unmanaged data into managed array

    - by JeffRSon
    I need to copy native (i.e. unmanaged) data (byte*) to managed byte array with C++/CLI (array). I tried Marshal::Copy (data is pointed to by const void* data and is dataSize bytes) array<byte>^ _Data=gcnew array<byte>(dataSize); System::Runtime::InteropServices::Marshal::Copy((byte*)data, _Data, 0, dataSize); This gives error C2665: none of the 16 overloads can convert all parameters. Then I tried System::Runtime::InteropServices::Marshal::Copy(new IntPtr(data), _Data, 0, dataSize); which produces error C2664: parameter 1 cannot be converted from "const void*" to "__w64 int". So how can it be done and is Marshal::Copy indeed the "best" (simplest/fastest) way to do so?

  • Catch/Raise event on table data update C#

    - by Incognito
    Hi, I have 24/7 service which keeps setup (configuration data) for charging, routing and etc in the Sql Server. Once it is started it loads the data from table using Linq2SQL and use the data through all the application. And we need a solution to update the setup data in the table without restarting the application. So I am interested is it possible to catch/determine that the table was updated so I can refresh the setup data in the application. I mean is it possible to have events which will raise when there is any delete, update or insert on the table. Thank you.

  • Copying just the data from one Database to another

    - by monksy
    I'm not sure if this is the site for this question or not [if so put in the comment or vote to move it] How can I copy only the data from one database to another within the same server on SQL Server 2005? The two databases have the same schema but not the same data. I'm trying to get the data from one database to another. I am not able to restore from a snapshot [that screws over the security settings on the database]. I'm not able to use the import data wizard, because that is trying to copy over schema data as well.

  • PHP Losing variable data

    - by Conor B
    Hi, I'm having an issue with PHP losing data in a variable. There is quite a bit of data in the variable, because it basically contains a binary file, but I'm wondering if this is cause for it to completely lose it's information. Looking at a snippet from my code which is used to deal with email attachments: var_dump($data) if (array_key_exists('filename', $params) || array_key_exists('name', $params)) { var_dump($data) ... } The first var_dump gives the desired output of the file: "string(283155) " --Apple-Mail-5-930065543 ... etc while the second gives an output of: string(0) "" ... string(0) "" Any idea why this is happening? Does PHP just drop data in variables if they are really large? (I didn't think so, as I've never had this problem before) If so, any workaround? Thanks!

  • Short POST data in HTTP

    - by Matt
    We're hosting a customer's Debian Linux web server. It's running a PHP based web application. The server is sitting behind our firewall with it's own virtual interface and port 80 is forwarded internally to a machine sitting in the DMZ. The issue we're having is that when data is posted to the server it seems to be being cut short for some users. It's reproducable for some users on the same box. But the same user sending the same data on the same lan on another PC it works. The data gets cut to around 1140 bytes I'm told. Any idea why this might be happening? The customer is blaming our firewall, but then surely we'd have issues with other services. I'm suspecting it's a problem with the website itself. Suggestions on how to isolate the problem would be of help. Our firewall is Astaro. EDIT: A customer has set the ethernet frame size temporarily to 500bytes on the server. This made it work for now! I know some of the customers are using an internet provider that runs PPPoE

  • Exporting Client Data from Groupwise 6.5 to Outlook 2010 without Crashing

    - by Adam Doherty
    My employer has recently moved from Novell GroupWise 6.5 to Exchange 2010. We've imposed mailbox limits on staff but we still need to move their old messages, contacts, calendars, etc. over to Outlook 2010. Our problem however is this, utilizing the Novell MAPI client is slow within Outlook 2010 and upon exporting messages to a PST file (for later re-attachment, and offline backup purposes) crashes the GroupWise server. Connecting to the server in Outlook via IMAP to export messages to PST is faster and apparently more stable but also crashes the server. We'll be keeping our GroupWise server online internally until then end of the year but I have staff with mailboxes approaching 12 gigabytes, which is fine if we're going to move the data to offline storage (DVD set) but if I keep crashing the server every time I try to get the data I'll just be spinning my wheels. In my first attempts, I tried to move mail for a staff member with 3GB of data. The transfer lasted roughly 8 hours before crashing. I'm wondering if there is an open source solution to my problem. Paid solutions exist but we're a not-for-profit organization and have too many staff to justify the costs of per seat licenses just to migrate mail.

  • 24TB RAID 6 configuration

    - by Phil
    I am in charge of a new website in a niche industry that stores lots of data (10+ TB per client, growing to 2 or 3 clients soon). We are considering ordering about $5000 worth of 3TB drives (10 in a RAID 6 configuration and 10 for backup), which will give us approximately 24 TB of production storage. The data will be written once and remain unmodified for the lifetime of the website, so we only need to do a backup one time. I understand basic RAID theory, however I am not experienced with it. My question is, does this sound like a good configuration? What potential problems could this setup cause? Also, what is the best way to do a one-time backup? Have two RAID 6 arrays, one for offsite backup and one for production? Or should I backup the RAID 6 production array to a JBOD? EDIT: The data server is running Windows 2008 Server x64. EDIT 2: To reduce rebuild time, what would you think about using two RAID 5's instead of one RAID 6?

  • Some URLs fail to load on Windows web portal

    - by jpolache
    I’m working in a large data center and have been assigned to troubleshoot and issue with a windows (IIS) web server that acts as a portal for a customer of the data center. This portal server is on a DMZ at the local data center. I don’t have access to the portal desktop and am relying on an off-site administrator to work with me to do testing and report the condition of the portal. He tells me there are no software firewalls or other filtering configured. While most of the remote web pages work fine, several of the URSs the portal is suppose to serve up fail to load. I had wireshark installed on the portal system and had a capture taken of one of the failures. I used IE to access one of the remote web servers at issue. I could see the TCP SYN-ACK coming back from the remote server, but after several HTTP GETs fail to get a response the portal server sends a reset. The webmaster of the remote web server assures me that no sites are being blocked. I had a capture taken outside the local firewall, so there should be no issue there. Another tech set up a laptop and used the IP address of the portal (we took the portal off-line for the test). The laptop loads the URL as expected. I tried having Firefox loaded to make sure that the HTTP GET was not mal-formed. Same failure as with IE. So, it seems it is not the remote web server or the network, because there was no problem with the laptop. At this point, I’m not sure what other questions to ask or tests to do.

  • Looking for recommendations on OCR problem - tabular numeric data

    - by ldigas
    I have 20 pages of experiment measurement data which I need to digitalize. The results are in tabular form, scanned in 600 dpi resolution, and as far as scans go, they came up pretty clean and readable. For an example of how it looks see here (but beware: it is a rather big scan; about 5Mb; no problem for any broadband connection, but dialups should approach with caution!) ... and I need it finished by sunday afternoon (:-o) <-- smiley in a state of panic (then why did't you start sooner?)... yea, yeah ... I know ... but, it came up late, and I wasn't thinking I was gonna need this data also. So, I'm looking for recommendations. I haven't much experience with OCR programs, save scanning a page or two of pure text, but just to mention, I haven't the wish also to test out every OCR program out there. So this isn't a "name your OCR favourite". What I'm looking is advice from someone who's done something like that, and his/hers experience on what would be the best way to undertake. I need the data in txt form but since it will have to be checked (by drawing it, and just simply watching whether some points "jump out") I'll probably be entering it in Excel at first.

  • changing filesystem format from xfs to ext4 without losing data

    - by A.Rashad
    I have a fresh Lucid Lynx (Ubuntu 10.04) running on a laptop. where I defined the filesystems as: mount point / on ext4 (46 Gb) mount point /home on jfs (63 GB) swap as 3 Gb I left the machine over night to do some task, without AC power supply. next day in the morning I found it on standby, task completed, but filesystem was not reachable. it gave me I/O error it seems that there is a problem with jfs and standby. anyways, to avoid any hassle, I want to move this mount point from jfs format to ext4. can I do this without losing data and without the need to place the data in a temporary location until transformation is done? sorry to mention that, but I recall back in the windows days, we would change a FAT16 to FAT32 or a FAT32 to NTFS without having to lose the data. I hope this is available on Linux. Update The /home filesystem was xfs not jfs, and it seems there is a bug with this filesystem for some reason, I had to re-install the OS twice until I ended up with ext4 for the entire / However, as a conclusion, it seems that there is no way to make a conversion

  • Western Digitial My Book: Can't access the data on the drive

    - by Bryan Denny
    My girlfriend has this external hard drive by Western Digital called a My Book. When the external drive is connected, it does not show it as an accessible disk drive on the computer. However, it shows up fine in Device Manager: I can also see it in Disk Management, but the volume is not mapped to a drive letter, nor can I change the drive letter: It only gives me access to Delete Volume: I would rather not lose the data on the drive if possible. What can I do from here to get to the data? Things I've tried/know: Uninstall drivers and re-install them Device does the same thing when attach to either her Win7 laptop or my Win8 laptop I don't think there's an issue with the HDD itself. No clicking noises, etc. I ran Western Digital Data LifeGuard Diangostics (DLGDIAG) and the SMART Status was a "PASS", all of the SMART Disk Information looked fine. I haven't had the time to run the diag tests yet but I do not believe it's a mechanical issue. The hard drive is inside of an enclosure, I have not attempted to pry the drive out yet. How can I get Windows to properly detect this drive?
