  • Name of several objects that have the same type

    - by Tomek Tarczynski
    Lets assume we have a class car. How would You name parameters of function that takes two different cars? void Race(Car first, Car second); or maybe void Race(Car car1, Car car2); The same situation with function that takes car and list of cars as a parameters. I'm used to name 'cars' for list of cars, so it is inconvenient to use names like: void Race(Car car, List<Car> cars); Any suggestions about names?

  • Format number as I type Expand this post

    - by conorhiggins
    Hi I am working on an app at the moment that requires number input to be formatted as the textfield changes as well as perform a calculation. I have the text fields set up so that as the user types notifications are passed out and a calculation is performed. However what I need to do now is format the text to be in this style: €1,000,000 rather than 1000000. I have this working for the output of the calculation already but everytime I try to apply it to the input text the simulator seems to crash or at least freezes for a while. I'd imagine its a simple enough fix.

  • How to add complex data type from Groovy script to the response in SoapUI

    - by SeeU
    My question is about putting data elements (from groovy script) in the response in SoapUI. I've an array of data that I would like to put in my response (in different tags/elements) I'm aware of putting a simple element like this: The element "MyName" in the Xml response: <ns:MyName>${MyName}</ns:MyName> Is mapped from the Groovy script by context.setProperty("MyName" , "My name" ) Now the problem: my Xml response looks like this: <soapenv:Body> <ns:GetDataSummaryResponse> <!--Optional:--> <ns:GetDataSummaryResult> <ns:DataSummary> <!--Zero or more repetitions:--> <ns:DataSummaryResponseDetail> <ns:Name>?</ns:Name> <!--Optional:--> <ns:DataProgress> <!--Optional:--> <From>?</From> <!--Optional:--> <Procent>?</Procent> <!--Optional:--> <To>?</To> <!--Optional:--> In Groovy I've built data array which is filled with data for example like this: context:[DataSummary:[DataSummaryResponseDetail:[Name:My name, DataProgress:[From:some text, Procent:some value, To:some text]]] In the response I'm able to see the whole value of ${DataSummary} but how do I get the element "Procent" I maybe am wrong about how to build my context data, but feel free to adjust!

  • wxpython: Updating a dict or other appropriate data type from wx.lib.sheet.CSheet object

    - by bvmou
    If I have a notebook with three spreadsheet widgets, what is the best way to have changes to the spreadsheet update a dictionary (or maybe an sqlite file?). Do all wx grid objects come with a built in dictionary related to the SetNumberRows and SetNumberCols? Basically I am looking for guidance on how to work with the user-input data from a spreadsheet widget, as in this example adapted from the tutorial on python.org: class ExSheet(wx.lib.sheet.CSheet): def __init__(self, parent): sheet.CSheet.__init__(self, parent) self.SetLabelBackgroundColour('#CCFF66') self.SetNumberRows(50) self.SetNumberCols(50) class Notebook(wx.Frame): def __init__(self, parent, id, title): wx.Frame.__init__(self, parent, id, title) nb = wx.Notebook(self, -1, style=wx.NB_BOTTOM) self.sheet1 = ExSheet(nb) self.sheet2 = ExSheet(nb) self.sheet3 = ExSheet(nb) nb.AddPage(self.sheet1, "Sheet1") nb.AddPage(self.sheet2, "Sheet2") nb.AddPage(self.sheet3, "Sheet3") self.sheet1.SetFocus() self.StatusBar()

  • Comparison operators not supported for type IList when Paging data in Linq to Sql

    - by Dan
    I can understand what the error is saying - it can't compare a list. Not a problem, other than the fact that I don't know how to not have it compare a list when I want to page through a model with a list as a property. My Model: Event : IEvent int Id string Title // Other stuff.. LazyList<EventDate> Dates // The "problem" property Method which pages the data (truncated): public JsonResult JsonEventList(int skip, int take) { var query = _eventService.GetEvents(); // Do some filtering, then page data.. query = query.Skip(skip).Take(take); return Json(query.ToArray()); } As I said, the above is truncated quite a bit, leaving only the main point of the function: filter, page and return JSON'd data. The exception occurs when I enumerate (.ToArray()). The Event object is really only used to list the common objects of all the event types (Meetings, Birthdays, etc - for example). It still implements IEvent like the other types, so I can't just remove the LazyList<EventDate> Dates' property unless I no longer implementIEvent` Anyway, is there a way to avoid this? I don't really want to compare a LazyList when I page, but I do not know how to resolve this issue. Thank you in advance! :)

  • How to declare a generic constraint that is a generic type

    - by HackedByChinese
    I have a two generic abstract types: Entity and Association. Let's say Entity looks like this: public class Entity<TId> { //... } and Association looks like this: public class Association<TEntity, TEntity2> { //... } How do I constrain Association so they can be of any Entity? I can accomplish it by the following: public class Association<TEntity, TId, TEntity2, TId2> where TEntity : Entity<TId> where TEntity2: Entity<TId2> { //... } This gets very tedious as more types derive from Association, because I have to keep passing down TId and TId2. Is there a simpler way to do this, besides just removing the constraint?

  • Injecting all registered instances of a type

    - by James L
    I can successfully perform container.ResolveAll<IMyInterface>(), and I get back an Enumerable containing every registered IMyInterface. However, I can't find a way to have these injected into the constructor of my class. I have tried using ResolvedArrayParameter(), but this gives me an empty enumerator. Am I doing something wrong, or could this be a bug in Unity?

  • Flex 4 how to layout spark controls in an html table type way

    - by Amy
    I have a group of controls and I want to organize them in a table like fashion. I want 1 row and 6 columns. Col 1,3,4,5,6 should all auto size to the contents and col 2 should take up the remaining available space. When the size of the group changes, only col2 width should change. I also want to be able to set the alignment of each cell. How can I do this in flex 4? I found a reference to mx:constraintColumns but this seems to be used with the canvas and in flex 4 adobe suggests not using canvases. Is there something similar in flex 4? I'm looking for something along the lines of Grid/Grid.ColumnDefinitions in silverlight.

  • Difficulty determining the file type of text database file

    - by Joseph Silvashy
    So the USDA has some weird database of general nutrition facts about food, and well naturally we're going to steal it for use in our app. But anyhow the format of the lines is like the following: ~01001~^~0100~^~Butter, salted~^~BUTTER,WITH SALT~^~~^~~^~Y~^~~^0^~~^6.38^4.27^8.79^3.87 ~01002~^~0100~^~Butter, whipped, with salt~^~BUTTER,WHIPPED,WITH SALT~^~~^~~^~Y~^~~^0^~~^6.38^4.27^8.79^3.87 ~01003~^~0100~^~Butter oil, anhydrous~^~BUTTER OIL,ANHYDROUS~^~~^~~^~Y~^~~^0^~~^6.38^4.27^8.79^3.87 ~01004~^~0100~^~Cheese, blue~^~CHEESE,BLUE~^~~^~~^~Y~^~~^0^~~^6.38^4.27^8.79^3.87 With those odd ~ and ^ separating the values, It also lacks a header row but thats ok, I can figure that out from the other stuff on their site: http://www.ars.usda.gov/Services/docs.htm?docid=8964 Any help would be great! If it matters we're making an open/free API with Ruby to query this data. Additionally I'm having a tough time posing this question so I've made it a community wiki so we can all pitch in!

  • construct graph from python set type.

    - by Vincent
    The sort question, is the an off the self function to make a graph from a set of python sets? The longer: I have several python set types. They each overlap or some are sub sets of others. I would like to make a graph (as in nodes and edges) with the edges weighted by common intersection of the sets. There are several graphing packages for python. (NetworkX, igraph,...) I am not familiar with the use of any of them. Will any of them make a graph directly from a list of sets ie, MakeGraphfromSets(alistofsets) If not do you know of an example of how to take the list of sets to define the edges. It actually looks like it might be straight forward but an example is always good to have.

  • Autofac: Reference from a SingleInstance'd type to a HttpRequestScoped

    - by Michael Wagner
    I've got an application where a shared object needs a reference to a per-request object. Shared: Engine | Per Req: IExtensions() | Request If i try to inject the IExtensions directly into the constructor of Engine, even as Lazy(Of IExtension), I get a "No scope matching [Request] is visible from the scope in which the instance was requested." exception when it tries to instantiate each IExtension. How can I create a HttpRequestScoped instance and then inject it into a shared instance? Would it be considered good practice to set it in the Request's factory (and therefore inject Engine into RequestFactory)?

  • Movable Type: MTEntries sort_by="title" doesn't really work

    - by kohei
    Hello Im trying to sort <MTEntries> by title. I know you can use <MTEntries sort_by="title" sort_order="ascend"> but this modifier some how prioritizes capitalized letters first to the sort. Im not sure if this is a glitch in the system but this modifier should sort by purely the alphabets(caps or no caps) used in the title. Example: I would like to sort these titles alphabetically: APRICOT Aligator ABBEY Apple If <MTEntries sort_by="title" sort_order="ascend"> is used: ABBEY APRICOT Aligator Apple But it really should be (and I want) ABBEY Aligator Apple APRICOT Would someone know how to achive this?

  • What type of websites does memcached speed up

    - by Saif Bechan
    I have read this article about 400% boost of your website. This is done by a combination of nginx and memcached. The how-to part of this website is quite good, but i mis the part where it says to what types of websites this applies. I know nginx is a http engine, I need no explanation for that. I thought memcached had something to do with caching database result. However i don't understand what this has to do with the http request, can someone please explain that to me. Another question I have is for what types of websites is this used. I have a website where the important part of the website consist of data that changes often. Often being minutes. Will this method still apply to me, or should I just stick with the basic boring setup of apache and nothing else.

  • ActionLink sending a model of a complex type

    - by Xenph Yan
    I'm trying to paginate the results of a "advanced search", I have a complex model that represents the search options; int ZipCode int MinAge int MaxAge Availability bool Monday bool Tuesday ... bool Friday Requirements bool FirstAid bool DriversLicense I'm using; <%: Html.ActionLink("Next »", "Save", "Notification", Model.options)%> Which correctly sends all the data at the first level, but anything that is a sub-object (Availability or requirements) isn't expanded in the URL, all I get is the class name and so I lose most of the search options when I click the link to change to a different page. Any thoughts?
