  • Dynamic Data Manipulation using XSLT from XML

    - by Imrul
    I am not working with XSLT not too long. I read that variable of XSLT can't be updated on the fly, so how can i do the following task. I want to sum up Purchase & Sales and put them into a variable, and make some decision according to these values. (For example, if Purchase is greater then sales then do something if not, do something else) <rows> <row> <col attr2="Purchase" >100.00</col> <col attr2="Sales" >100.00</col> </row> <row > <col attr2="Purchase" >19.16</col> <col attr2="Sales" >12.94</col> </row> <row > <col attr2="Purchase" >0.67</col> <col attr2="Sales" >2.74</col> </row> <row > <col attr2="Purchase" >71.95</col> <col attr2="Sales" >61.54</col> </row> <row > <col attr2="Purchase" >3.62</col> <col attr2="Sales" >14.72</col> </row> <row > <col attr2="Purchase">8.80</col> <col attr2="Sales">1.22</col> </row> <row > <col attr2="Purchase" >-4.28</col> <col attr2="Sales" >6.53</col> </row> </rows> if anyone knows, please help me.

  • NSPredicate by NSManagedObject for many-to-one lookups

    - by niklassaers
    Hi guys, I've got the scenario with two NSManagedObjects, Arm and Person. Between them is a many-to-one relationship Person.arms and inverse Arm.owner. I'd like to write a simple NSPredicate where I've got the NSManagedObject *arm and I'd like to fetch the NSManagedObject *person that this arm belongs to. I could make a textual representation and look for that, but is there a better way where I can look it up by identity? Something like this perhaps? NSEntityDescription *person = [NSEntityDescription entityForName:@"Person" inManagedObjectContext:MOC]; NSPredicate *personPredicate = [NSPredicate predicateWithFormat:@"%@ IN arms", arm]; Cheers Nik

  • Saving multiple objects in a single call in rails

    - by CaptnCraig
    I have a method in rails that is doing something like this: a = Foo.new("bar") a.save b = Foo.new("baz") b.save ... x = Foo.new("123", :parent_id => a.id) x.save ... z = Foo.new("zxy", :parent_id => b.id) z.save The problem is this takes longer and longer the more entities I add. I suspect this is because it has to hit the database for every record. Since they are nested, I know I can't save the children before the parents are saved, but I would like to save all of the parents at once, and then all of the children. It would be nice to do something like: a = Foo.new("bar") b = Foo.new("baz") ... saveall(a,b,...) x = Foo.new("123", :parent_id => a.id) ... z = Foo.new("zxy", :parent_id => b.id) saveall(x,...,z) That would do it all in only two database hits. Is there an easy way to do this in rails, or am I stuck doing it one at a time?

  • Lose changed data in session

    - by user150528
    Our asp.net 2.0 application has a very long process (synchronized) before sending response back to client. I observed that a second request, exactly same the initial one, was sent after client IE8 waited response for a long period of time while our application was still processing the first request. I use page session with predefined key to store a flag when the initial request arrives and then starts long process while client IE waits for the response, so if second request comes in, our application checks the session value. After our application sets the session flag and starts processing, I use Fiddler “Abort Session” to abort the initial request, right away the second request (same as the first one) is sent automatically, but session value set earlier seems no longer exist. Any thoughts?

  • Is there a way to generate a short random id, avoiding collisions, without hitting persistent storag

    - by bshacklett
    If you've used GoToMeeting, that's the type of ID I want. I'd like it to be random so that it obfuscates the number of items being tracked and short, so that it's easy to reference manually; UUIDs are way too long. I'd like to avoid hitting persistent storage merely for performance reasons, but I can't think of any other way to avoid collisions. Is 9 digits enough to do something time-based?

And the font is not changing. here is the snippet of my code: NSString* str = @"\u05D0\u05D1\u05D2"; [mMatchingLabel setText:str]; mMatchingLabel.font = [UIFont fontWithName:@"David New Hebrew" size:26]; But when I write for example : NSString* str = @"label"; [mMatchingLabel setText:str]; mMatchingLabel.font = [UIFont fontWithName:@"David New Hebrew" size:26]; The font effect is evident.

  • Algorithm for data alignment of float arrays in Java

    I have two float arrays representing y values in a line chart. Now I want to align these two charts. Are there any existing algorithms for alignment of the two arrays? A very simple example a: 2.5 1.3 1.6 4.2 3.6 b: 3.3 1.4 2.5 1.3 1.6 Now after alignment it should be: 2.5 1.3 1.6 4.2 3.6 3.3 1.4 2.5 1.3 1.6

  • How can I dynamically add an <object> tag with JavaScript in IE?

    - by Detlef D. Doerscheln
    I have to add either an embed tag for Firefox or an object tag for Internet Explorer with JavaScript to address the appropriate ActiveX / Plugin depending on the browser. The plugin could be missing and needs to get downloaded in this case. The dynamically added embed tag for Firefox works as expected. The dynamically added object tag for Internet Explorer seems to do nothing at all. The object tag needs the following attributes to function properly. id ="SomeId" classid = "CLSID:{GUID}" codebase = "http://www.MyActicexSource.com/MyCuteActivex.CAB#Version=2,0,0,1" Even a general working idea or method would be nice. Thanks!

  • How to move an element in a sorted list and keep the CouchDb write "atomic"

    - by karlthorwald
    I have elements of a list in couchdb documents. Let's say these are 3 elements in 3 documents: { "id" : "783587346", "type" : "aList", "content" : "joey", "sort" : 100.0 } { "id" : "358734ff6", "type" : "aList", "content" : "jill", "sort" : 110.0 } { "id" : "abf587346", "type" : "aList", "content" : "jack", "sort" : 120.0 } A view retrieves all "aList" documents and displays them sorted by "sort". Now I want to move the elements, when I want to move "jack" to the middle, I could do this atomic in one write and change it's sort key to 105.0. The view now returns the documents in the new sort order. After a lot of sorting I could end up with sort keys like 50.99999 and 50.99998 after some years and in extreme situations run out of digits? What can you recommend, is there a better way to do this? I'd rather keep the elements in seperate documents. Different users might edit different elements in parallel (which also can get tricky). Maybe there is a much better way?

  • Accessing structure through pointers [c]

    - by Blackbinary
    I've got a structure which holds names and ages. I've made a linked-list of these structures, using this as a pointer: aNode *rootA; in my main. Now i send **rootA to a function like so addElement(5,"Drew",**rootA); Because i need to pass rootA by reference so that I can edit it in other functions (in my actual program i have two roots, so return will not work) The problem is, in my program, i can't say access the structure members. *rootA->age = 4; for example doesnt work. Hopefully you guys can help me out. Thanks!

  • Error messages for model validation using data annotations

    - by oneBelizean
    Given the follow classes: using System.ComponentModel.DataAnnotations; public class Book{ public Contact PrimaryContact{get; set;} public Contact SecondaryContact{get; set;} [Required(ErrorMessage="Book name is required")] public string Name{get; set;} } public class Contact{ [Required(ErrorMessage="Name is required")] public string Name{get; set;} } Is there a clean way I can give a distinct error message for each instance of Contact in Book using DataAnnotations? For example, if the name was missing from the PrimaryContact instance the error would read "primary contact name is required". My current solution is to create a validation service that checks the model state for field errors then remove said errors and add them back using the specific language I'd like.

    I have a javascript that is calling a function addData(param1,param2,param3,param4) which is calling addClip at the end And I need to pass those to a backing bean. <a4j:form> <a4j:jsFunction name="addClip" action="#{backingBean.goGo}"> <a4j:actionparam name="param1" assignTo="#{backingBean.param1}"/> </a4j:jsFunction> </a4j:form> But I can't seem to pass any values to the backingbean. I've even tried setting a static value for the actionparam. But when I try to do a Systemout on the setParam1 method it only prints out null. Have I missed anything important?

  • Binning a numeric variable in R

    - by McPeterson
    I have a vector X that contains positive numbers that I want to bin/discretize. For this vector, I want the numbers [0, 10) to show up just as they exist in the vector, but numbers [10,∞) to be 10+. I'm using: x <- c(0,1,3,4,2,4,2,5,43,432,34,2,34,2,342,3,4,2) binned.x <- as.factor(ifelse(x > 10,"10+",x)) but this feels klugey to me. Does anyone know a better solution or a different approach? mcpeterson

  • How to delete data in DB efficiently using LinQ to NHibernate (one-shot-delete)

    - by kastanf
    Hello, producing software for customers, mostly using MS SQL but some Oracle, a decision was made to plunge into Nhibernate (and C#). The task is to delete efficiently e.g. 10 000 rows from 100 000 and still stay sticked to ORM. I've tried named queries - link already, IQuery sql = s.GetNamedQuery("native-delete-car").SetString(0, "Kirsten"); sql.ExecuteUpdate(); but the best I have ever found seems to be: using (ITransaction tx = _session.BeginTransaction()) { try { string cmd = "delete from Customer where Id < GetSomeId()"; var count = _session.CreateSQLQuery(cmd).ExecuteUpdate(); ... Since it may not get into dB to get all complete rows before deleting them. My questions are: If there is a better way for this kind of delete. If there is a possibility to get the Where condition for Delete like this: Having a select statement (using LinQ to NHibernate) = which will generate appropriate SQL for DB = we get that Where condition and use it for Delete. Thanks :-)

  • Databinding to type double - decimal mark lost

    - by user1277327
    I have a project where I'm databinding a gridview to a list, where one column is databound to a gridview. The problem I have is that with the double being 5.5 on one computer it appears as 5.5 in the gridview. But on another it looks like 55, the decimal mark dissapears. So 3.14 will look like 314 etc. The error occurs with the following code: myDatagrid.ItemsSource = someList; Binding binding = new Binding("DoubleValue"); myColumnInDatagrid.Binding = binding; I've also tried using a very simple valueconverter, that just return the double, and parsed it in ConvertBack. I'm pretty new to WPF so I'm sorry if I've made some obvious mistakes, I just don't understand why it works on one computer but not on the other. Perhaps it should be noted that both of the computers use the same operating system, with the same language settings (afaik at least).
