  • Accessing Linq data in telerik grid ItemCreated method

    - by Jack
    Not sure if the title of this question makes sense, but here's my problem: I have a telerik grid bound to a Linq data object, however, I limit the fields returned: <IQueryable>filter = data.Select(x => new {x.ID, x.Name, x.Age}); I would like to access these fields in the ItemCreated method of the grid: protected void rgPeople_ItemCreated(object sender, GridItemEventArgs e) { Telerik.Web.UI.GridDataItem item = (GridDataItem)e.Item; ?????? Person = (???????)e.Item.DataItem; } What do I declare ?????? as so that I can use: String ID = Person.ID; String Name = Person.Name; etc

  • Inserting the record into Data Base through JPA

    - by vinay123
    In my code I am using JSF - Front end , EJB-Middile Tier and JPA connect to DB.Calling the EJB using the Webservices.Using MySQL as DAtabase. I have created the Voter table in which I need to insert the record. I ma passing the values from the JSF to EJB, it is working.I have created JPA controller class (which automatcally generates the persistence code based on the data base classes) Ex: getting the entity manager etc., em = getEntityManager(); em.getTransaction().begin(); em.persist(voter); em.getTransaction().commit(); I have created the named query also: @NamedQuery(name = "Voter.insertRecord", query = "INSERT INTO Voter v values v.voterID = :voterID,v.password = :password,v.partSSN = :partSSN,v.address = :address, v.zipCode = :zipCode,v.ssn = :ssn, v.vFirstName = :vFirstName,v.vLastName = :vLastName,v.dob = :dob"),But still not able to insert the record? Can anyone help me in inserting the record into the Data base through JPA.(Persistence object)?

  • Best way to save complex Python data structures across program sessions (pickle, json, xml, database

    - by Malcolm
    Looking for advice on the best technique for saving complex Python data structures across program sessions. Here's a list of techniques I've come up with so far: pickle/cpickle json jsonpickle xml database (like SQLite) Pickle is the easiest and fastest technique, but my understanding is that there is no guarantee that pickle output will work across various versions of Python 2.x/3.x or across 32 and 64 bit implementations of Python. Json only works for simple data structures. Jsonpickle seems to correct this AND seems to be written to work across different versions of Python. Serializing to XML or to a database is possible, but represents extra effort since we would have to do the serialization ourselves manually. Thank you, Malcolm

  • how to get the camera data

    - by beof
    Hello ,guys, My app needs to get the camera data from Iphone. In my ImagePickerController, there is overlayView drawing realtime indications. I use UIGetScreenImage() to get the screenshot, and I also dump overlayview to image, then I can restore the original Image based on these two images. if the overlayView is still, it works quite well, but if the overlayView keeps changing, UIGetScreenImage() can not keep up with it. For example,if the overlayView changes from a rectangle to a circle, then calling UIGetScreenImage() returns with a rectangle on top of it. Is there a way to get the realtime camera data? I really appreciate if someone could help.

  • Grouping data in an NSMutable array

    - by padatronic
    Hi guys, I have an array i load with lots of data from an xml file. I am displaying this on a tableview and then when you click on say an author it goes through to display all their books. At the minute my NSMutableArray has an entry for every each book with title, author and so on. So in the table of authors it display the authors name as many times as they have books. I want to group the array data so the table only displays each author once but the author contains an array of his books. Seems simple but I can't find a group method for arrays. thanks peeps

  • Range partition skip check

    - by user289429
    We have large amount of data partitioned on year value using range partition in oracle. We have used range partition but each partition contains data only for one year. When we write a query targeting a specific year, oracle fetches the information from that partition but still checks if the year is what we have specified. Since this year column is not part of the index it fetches the year from table and compares it. We have seen that any time the query goes to fetch table data it is getting too slow. Can we somehow avoid oracle comparing the year values since we for sure know that the partition contains information for only one year.

  • Huge amount of time sending data with suds and proxy

    - by Roman
    Hi everyone, I have the following code to send data through a proxy using suds: import suds t = suds.transport.http.HttpTransport() proxy = urllib2.ProxyHandler({'http': 'http://192.168.3.217:3128'}) opener = urllib2.build_opener(proxy) t.urlopener = opener ws = suds.client.Client('http://xxxxxxx/web.asmx?WSDL', transport=t) req = ws.factory.create('ActionRequest.request') req.SerialNumber = 'asdf' req.HostName = 'hola' res = ws.service.ActionRequest(req) I don't know why, but it can be sending data above 2 or 3 minutes, or even more and it raises a "Gateway timeout" exception sometimes. If I don't use the proxy, the amount of time used is above 2 seconds or less. Here is the SOAP reply: (ActionResponse){ Id = None Action = "Action.None" Objects = "" } The proxy is running right with other requests through urllib2, or using normal web browsers like firefox. Does anyone have any idea what's happening here with suds? Thanks a lot in advance!!!

  • jQuery.Ajax makes the wrong request with array data

    - by user46503
    Hello, I have the following array: var idParam = ["1","2","3"]; I want to send this data as request using jQuery.ajax, what I'm doing: $.ajax({ type: "GET", url: "Services/GetInfo.ashx", data: { "id": idParam }, contentType: "application/text", dataType: "json", success: function(result) { ... }, error: function(XMLHttpRequest, textStatus, errorThrown) { ... } }); But as result I have the following ugly string: ?id[]=1&id[]=2&id[]=4 (actually it's much uglier:id%5B%5D=1&id%5B%5D=2&id%5B%5D=4). What to do to get the normal string like: id=1&id=2&id=4 ?? Thanks

  • WPF Validation of clipboard Data

    - by Peter
    Hello normal validation is always related to some control, but in my case there is no control to fire validation when its content changes and to show errortemplate to the user. because the data to be validated is in the cipboard. when the user presses "PASTE" button viewmodel processes the data and finds it to be invalid. but what is the best way to invoke WPF validation in this case? as far as i understand using IDataErrorInfo is the way to go, but what is the best way to start validation. and whst is the best way of displaying the error? errortemplate of the button element? Thanks a lot for help. Peter

  • Problem drawing a polygon on data clusters in MATLAB

    - by Hossein
    Hi, I have some data points which I have devided into them into some clusters with some clustering algorithms as the picture below:(it might takes some time for the image to appear) Each color represents different cluster. I have to draw polygons around each cluster. I use convhull for this reason. But as you can see the polygon for the red cluster is very big and covers a lot of areas, which is not the one I am looking for. I need to draw lines(ploygons) exactly around my data sets. For example in the picture above I want a polygon that is drawn exactly the same(and around) as the red cluster with the 3 branches. In other words, in this case I need a polygon with 3 branches to cover my red clusters not that big polygon that covers the whole area. Can anyone help me with this? Please Note that the solution should be general, because the clusters will change in each run of the algorithm, so it needs to be in a way that is general.

  • Fill object data from several tables using hibernate mapping

    - by Udo Fholl
    Hi all, I'd like to know if it is possible to fill up a class data from database using the hibernate hbm (mapping). For instance: public class someClass { List<OtherClass> otherClasses; List<YetAnotherClass> yetAnotherClasses; //Constructors ? class OtherClass { String name; //setters, getters } class YetAnotherClass { String name; //setters, getters } //setters, getters } Using an hbm can I fill in the data from tables OTHER_CLASS_TABLE and YET_ANOTHER_CLASS_TABLE? I have no such SOME_CLASS_TABLE since this info is for viewing only. I've been playing with the <join table=""><subselect> and different constructors... But it is not working Thanks! Sorry for my english!

  • .NET Data Adapter Timeout SP Issue

    - by A-B
    We have a SQL Server stored procedure that runs fine in SQL Manager directly, does a rather large calculation but only takes 50-10 seconds max to run. However when we call this from the .NET app via a data adapter it times out. The timeout however happens before the timeout period should, we set it to 60 seconds and it still times out in about 20 seconds or less. I've Googled the issue and seen others note issues where a SP works fien directly but is slow via a data adpater call. Any ideas on how to resolve this?

  • 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?

  • Importing Sqlite data into Google App Engine

    - by Keck
    I have a relatively extensive sqlite database that I'd like to import into my Google App Engine python app. I've created my models using the appengine API which are close, but not quite identical to the existing schema. I've written an import script to load the data from sqlite and create/save new appengine objects, but the appengine environment blocks me from accessing the sqlite library. This script is only to be run on my local app engine instance, and from there I hope to push the data to google. Am I approaching this problem the wrong way, or is there a way to import the sqlite library while running in the local instance's environment?

  • Data Types and Structs

    - by dubya
    I'm reviewing for a test, and I am stumped by this question. Consider the following declarations: enum CategoryType {HUMANITIES, SOCIALSCIENCE, NATURALSCIENCE}; const int NUMCOURSES = 100; struct CourseRec { string courseName; int courseNum; CategoryType courseCategory; }; typedef CourseRec CourseList [NUMCOURSES]; CourseList courses; int index1, index2; What is the data type of the expression courses[index1] .courseName[index2] ? (a) CourseList (b) CourseRec (c) string (d) char (e) none; the expression is syntactically invalid I thought that the answer would be string, since courseName is a string, or maybe even CourseRec, since it is in the struct, but the answer is (d)char. Why is this a char data type? Any help is greatly appreciated.

  • Does correcting a value in an validation method mark the object as dirty?

    - by dontWatchMyProfile
    From the docs: If you change the input value in a validate:error: method, you must ensure that you only change the value if it is invalid or uncoerced. The reason is that, since the object and context are now dirtied, Core Data may validate that key again later. If you keep performing a coercion in a validation method, this can therefore produce an infinite loop. So when I modify a value in a validation method, the context gets dirtied? And the next time I save, the validation happens again - and when I change the value even if the validation is OK, then the context is again dirtied, and revalidated again - and I change the value, and Core Data validates, again, because the context is dirtied. And so on...for ever... is that right? Or did they try to say something different?

  • Using a "vo" for joined data?

    - by keithjgrant
    I'm building a small financial system. Because of double-entry accounting, transactions always come in batches of two or more, so I've got a batch table and a transaction table. (The transaction table has batch_id, account_id, and amount fields, and shared data like date and description are relegated to the batch table). I've been using basic vo-type models for each table so far. Because of this table structure structure, though, transactions will almost always be selected with a join on the batch table. So should I take the selected records and splice them into two separate vo objects, or should I create a "shared" vo that contains both batch and transaction data? There are a few cases in which batch records and/or transaction records. Are there possible pitfalls down the road if I have "overlapping" vo classes?

  • What exactly does raw microphone data represent?

    - by esperantist
    I'm using PyAudio, a PortAudio wrapper for Python. I'm getting data from a microphone. Data which is represented by a continuous stream of bytes divided into chunks (of a size determined by me). I've tried to plot the signal, assuming the bytes represent the current signal amplitude, but I get an interesting image that I can't easily describe. ^^ It seems to be composed of two waves, one shifted from the other. What exactly do the particular bytes represent, and how does this change when I'm recording only one channel, instead of two? Any explanations, suggestions, code snippets, anything, very welcome! (I'm new at this.) Thanks!

  • ASP.NET and SQL server with huge data sets

    - by Jake Petroules
    I am developing a web application in ASP.NET and on one page I am using a ListView with paging. As a test I populated the table it draws from with 6 million rows. The table and a schema-bound view based off it have all the necessary indexes and executing the query in SQL Server Management Studio with SELECT TOP 5 returned in < 1 second as expected. But on the ASP.NET page, with the same query, it seems to be selecting all 6 million rows without any limit. Shouldn't the paging control limit the query to return only N rows rather than the entire data set? How can I use these ASP.NET controls to handle huge data sets with millions of records? Does SELECT [columns] FROM [tablename] quite literally mean that for the ListView, and it doesn't actually inject a TOP <n> and does all the pagination at the application level rather than the database level?
