• Sort each standalone line alphabetically

  - by Daniel

  I want to sort some items in alphabetic order, but in a very specifc way. I have, for example, the following list, each item separated by comma: monkeys, dogs, cats pineapple, banana, orange yellow, red, blue, green silver, gold, platinum delphi, java, c++, visual basic I want to sort each line alphabetically, WITHOUT changing line order. My desired result would be: cats, dogs, monkeys banana, orange, pineapple blue, green, red, yellow gold, platinum, silver c++, delphi, java, visual basic My target list has got 3000+ lines, so it should be an automated process. Thanks!

• Extension method question. Why do I need to use someObj = someObj.somemethod();

  - by Kettenbach

  Hi All, I have a simple extension method that I would like to use to add an item to an array of items. public static T[] addElement<T>(this T[] array, T elementToAdd) { var list = new List<T>(array) {elementToAdd}; return list.ToArray(); } this works ok, but when I use it, I am having to set the array equal to the return value. I see that I am returning an Array. I likely want this method to be void, but I would like the item added. Does anyone have any ideas on what I need to do , to make this work the way I am wanting? Instead of someArray = someArray.addElement(item), I just want to do someArray.addElement(item) and then someArray be ready to go. What am I missing here? Thanks, ~ck in San Diego

• Nhibernate Complex Type binding

  - by user329983

  I have two oracle user defined types: Audit_Type – A normal object with two fields a string and a number Audit_Table_Type – A table of audit_types, (an array) I have a stored procedure that takes as a parameter an Audit_Table_Type. List<Audit_Type> table = new List<Audit_Type>(); var query = session.CreateSQLQuery("call Audit_Rows(Audit_Table_Type(:table))") .SetParameterList("table", table, NHibernateUtil.Custom(typeof(AuditTypeUDT))) This is what I did intuativly created the ICompositeType and just set in a list of them in but this gives me nothing close to what I wanted. I couldn’t figure out how to bind to a table at all. I have built the inline sql that would do this for me but it would destroy my shared pool (not using binds). So a General question how do I bind to complex/composite types using Nhibernate?

• How to build up a lookup table in microcontroller?

  - by GiGi

  Hi, I am so confused about how to build up a 3-dimension lookup table. Is the template as follows: create a 3 dimensional array to store data. Then create linked list. Then create function 'insert' to put all the data into the array? As some book said, linked list should be static const, is it need to create another function to expand the list? Because the lookup table should be used in a microcontroller, it only needs to finish the operation of putting the data into the array and whenever want to find the data, it will be fast and easy to search. Could you help me with that and give me some suggestions? Thank you.

• Check keyword popularity of 2000 phrases?

  - by Mark

  I just found a list of about 2000 car manufacturers which I want to put into a drop-down list... but 2000 is probably a bit too many, so I want to filter it down to maybe the top 100 most popular cars. I figure I can just use Google search popularity to give me a rough estimate of how popular the car is... but I can't find a tool that will let me query 2000 keywords. Anyone know of one?

• Dijit Combobox filter autocomplete

  - by Apps

  I'm using dijit combobox for populating a JSON List. Also I'm using ItemFileReadStore for getting the JSON data from the server. Once the data is downloaded, when I click on the combobox it shows all the data. But I don't want the user to see all the data. The user should see the list only when he types something. I tried using queryExpr parameter-${0}*. But at that time the list is not populated.Can someone please help me to fix it? Any help will be greatly appreciated Thanks, Apps

• Using the StackTrace Class in a production environment to get calling method info

  - by andy

  hey guys We have a "log" class which uses Relection.MethodBase to send current class info to the log. The reflection.MethodBase stuff happens in the class itself. However, I'd like to move that stuff to a single external "log" singleton type class. In this scenario the external log class needs to get the CALLING info, not the current method info. I'm using stacktrace to do this, which isn't in the Reflection namespace. Can I guarantee that "that" specific information (calling method) will be there in a production environment? var stackTrace = new StackTrace(); return LogManager.GetLogger(stackTrace.GetFrame(1).GetMethod().DeclaringType); cheers!

• Setting selected item on Listbox in Silverlight - Windows Phone 7

  - by Fishcake

  I have a databound Listbox bound to a generic list as follows (Provider is a very simple class that just includes a single property (Name). ProviderList = new List<Provider>(); //Populate list Providers.ItemsSource = ProviderList; I can save the selected item with no problem but I can't manage to set the selected item from code afterwards. I am trying to do so as follows: int x = Providers.Items.IndexOf((Provider)_Settings["provider"]); However IndexOf() is always returning -1. If I inspect both Providers.Items[1] and _Setting["provider"] at runtime using the immediate window they both return {StoreRetrieveData.Provider} Name: "Greenflag" Am I doing something wrong (well clearly I am)?

• Error message when trying to insert method into touchesBegan

  - by Rob

  I am trying to create a new method within my TapDetectingImageView file and it's giving me a warning that it cannot find the method even though I have it declared in the .h file. The specific three warnings all point to the @end line in the .m file when I build it and they say: "Incomplete implementation of class 'TapDetectingImageView' ; 'Method definition for '-functionA:' not found" ; "Method definition for '-functionB:' not found" What am I missing? Am I not allowed to do this in a protocol file like TapDetectingImageView? In my .h file is: @interface TapDetectingImageView : UIImageView <AVAudioPlayerDelegate> { id <TapDetectingImageViewDelegate> delegate; } @property (nonatomic, assign) id <TapDetectingImageViewDelegate> delegate; -(void) functionA:(NSString*)aVariable; -(void) functionB:(NSString*)aVariable; @end In my .m file is: -(void)functionA:(NSString*)aVariable { // do stuff in this function with aVariable } -(void)functionB:(NSString*)aVariable { // do stuff in this function with aVariable }

• dijit hovering MenuItem issue

  - by John

  I have a dijit.layout.TabContainer on my form. I resize the browser window in such a way that all tabs won't fit in a single screen. In this case dijit automatically adds a drop-down button at the right end of the TabContainer (I get this for free). If I click on the drop-down button then I get the full List of Tab Names. Hovering over the List of Tab Names (which is in fact a collection of menu items) it blanks out the menu item name which I'm currently over. e.g. Full List: Tab1 Tab2 Tab3 Hovering over Tab2 I get: Tab1 Tab3 I get the same issue with any other dijit.Menu, dijit.MenuItem AND I get the same issue on IE, Firefox, Chrome. I haven't tested on any other browser. Thanks.

• Passing variable string to create arrays (Android)

  - by dweebsonduty

  Hello all, I am a newb to Android and Java and want to write a funtion that will display a list based on a varable that I pass to the function. The function is below and the code below creates an array out of a string called type, but what I want to do is pass it a variable string and have it build a list based on that string. So if I wanted the type list I would say list_it("type") But if I try something like getResources().getStringArray(R.array.thelist); it doesn't work. Can someone point me in the right direction? public void list_it(String thelist){ String[] types = getResources().getStringArray(R.array.type); ArrayAdapter<String> mAdapter = new ArrayAdapter<String>(this, R.layout.list_item1, types); setListAdapter(mAdapter); ListView lv = getListView(); lv.setTextFilterEnabled(true); }

• Storing an arbitrary R object onto HDD?

  - by Harokitty

  I understand that we can export data matrices to csv or xlsx files. What about complex objects like lm? For example, in my work I might have a list of length 1000, each with a single lm() object. Each time I load R I have to wait a long time to populate the 1000 length list with these lm objects with a for loop or a lapply. I would rather just save the list somewhere on my HDD at the end of a session and open it at the start of the next session.

• how is a macro expanded in clojure?

  - by john wang

  In the book Programming Clojure(Stuart), when read how macros are expanded I got confused. user=> (defmacro chain ([x form] (list '. x form)) ([x form & more] (concat (list 'chain (list '. x form)) more))) #'user/chain The above macro can be expanded as: user=> (macroexpand '(chain a b c)) (. (. a b) c) But the following is only expanded to the first level: user=> (macroexpand '(and a b c)) (let* [and__3822__auto__ a] (if and__3822__auto__ (clojure.core/and b c) and__3822__auto__)) The and macro source: user=> (source and) (defmacro and([] true) ([x] x) ([x & next] `(let [and# ~x] (if and# (and ~@next) and#)))) Why is the chain macro expanded all the way but the and not ? Why is it not expanded to something like the following: user=> (macroexpand '(chain a b c d)) (. (chain a b c) d)

• Collectable<T> serialization, Root Namespaces on T in .xml files.

  - by Stacey

  I have a Repository Class with the following method... public T Single<T>(Predicate<T> expression) { using (var list = (Models.Collectable<T>)System.Xml.Serializer.Deserialize(typeof(Models.Collectable<T>), FileName)) { return list.Find(expression); } } Where Collectable is defined.. [Serializable] public class Collectable<T> : List<T>, IDisposable { public Collectable() { } public void Dispose() { } } And an Item that uses it is defined.. [Serializable] [System.Xml.Serialization.XmlRoot("Titles")] public partial class Titles : Collectable<Title> { } The problem is when I call the method, it expects "Collectable" to be the XmlRoot, but the XmlRoot is "Titles" (all of object Title). I have several classes that are collected in .xml files like this, but it seems pointless to rewrite the basic methods for loading each up when the generic accessors do it - but how can I enforce the proper root name for each file without hard coding methods for each one? The [System.Xml.Serialization.XmlRoot] seems to be ignored.

• What is the best practice for accessing Model using MVVM pattern

  - by Dzenand

  I have a database that communicates with webservices with my Model (own thread) and exposes Data Objects. My UI application consists of different Views and ViewModels and Custom Controls. I'm using ServiceProvider (IServiceProvider) to access the Model and route the events to the UI thread. Communication between the ViewModels is handeled by a Messenger. Is this way to go? I was also wondering what is the best way to strucutre the DataObjects At the moment i have the DataObjects that have a hierarchy structure but does not support INotifyProperty though the children list are of type of ObservableCollection. I have no possiblity to implement notifypropertychange on the properties. I was wondering the best way of making them MVVM friendly. Implementing a partial class and adding all the properties or commands that are necessary or wrapping all the DataObjects and keep the Model list and MVVM list in sync. All thoughts and ideas are appreciated.

• reloading table

  - by edie

  Hi... I've have a table view that consist of item list that depends on the item that were purchased using in app purchasing. My question was how can I reload the tableView when the purchasing was completed/(or when new item was added on my list). The response of the storekit takes time to complete. Are there anyways to tell the app that the purchasing was completed and new item was added on my list so that I can reload my tableView. At this time I reloading my table view by adding [myTableView reloadData] in viewWillAppear method. But what if the user was already viewing the tableView, I can't reload the tableView because the viewWillAppear had passed. thanks...

• a nicer way to create structs in a loop

  - by sandra

  Hi guys, I haven't coded in C++ in ages. And recently, I'm trying to work on something involving structs. Like this typedef struct{ int x; int y; } Point; Then in a loop, I'm trying to create new structs and put pointers to them them in a list. Point* p; int i, j; while (condition){ // compute values for i and j with some function... p = new Point; p* = {i, j}; //initialize my struct. list.append(p); //append this pointer to my list. } Now, my question is it possible to simplify this? I mean, the pointer variable *p outside of the loop and calling p = new Point inside the loop. Isn't there a better/nicer syntax for this?

• F# replace ref variable with something fun

  - by Stephen Swensen

  I have the following F# functions which makes use of a ref variable to seed and keep track of a running total, something tells me this isn't in the spirit of fp or even particular clear on its own. I'd like some direction on the clearest (possible fp, but if an imperative approach is clearer I'd be open to that) way to express this in F#. Note that selectItem implements a random weighted selection algorithm. type WeightedItem(id: int, weight: int) = member self.id = id member self.weight = weight let selectItem (items: WeightedItem list) (rand:System.Random) = let totalWeight = List.sumBy (fun (item: WeightedItem) -> item.weight) items let selection = rand.Next(totalWeight) + 1 let runningWeight = ref 0 List.find (fun (item: WeightedItem) -> runningWeight := !runningWeight + item.weight !runningWeight >= selection) items let items = [new WeightedItem(1,100); new WeightedItem(2,50); new WeightedItem(3,25)] let selection = selectItem items (new System.Random())

• Assign multiple css classes to a table element in Rails

  - by Eric K

  I'm trying to style a table row using both cycle and a helper, like shown: <tr class= <%= cycle("list-line-odd #{row_class(item)}", "list-line-even #{row_class(item)}")%> > However, when I do this, the resulting HTML is: <tr class = "list-line-odd" lowest-price> with the return from the helper method not enclosed in the quotes, and therefore not recognized. Here's the helper I'm using: def row_class(item) if item.highest_price > 0 and item.lowest_price > 0 and item.highest_price != item.lowest_price if item.current_price >= item.highest_price "highest-price" elsif item.current_price <= item.lowest_price "lowest-price" end end end I must be missing something obvious, but I just can't figure out how to wrap both the result of cycle and the helper method return in the same set of quotes. Any help would be greatly appreciated!

• How do I configure NetBeans to only step through Java code that I've written.

  - by blissapp

  Am I missing something? I'm delighted that all that code is there showing how the generic collections work etc. However when I want to simply walk my code I'm forever finding myself going deeper into Java's own library code than I care to. Is it possible to simply disable that when stepping code - I want to treat all of that stuff as a Black Box, code stepping is just for stuff I've written. And you know what, now I've got that capability, is it possible to wrap up my own code that way too so that I can step just the bits I'm most interested in? And if i can't easily in netbeans, is it possible in eclipse? thanks

• typeof === "undefined" vs. != null

  - by Thor Thurn

  I often see JavaScript code which checks for undefined parameters etc. this way: if (typeof input !== "undefined") { // do stuff } This seems kind of wasteful, since it involves both a type lookup and a string comparison, not to mention its verbosity. It's needed because 'undefined' could be renamed, though. My question is: How is that code any better than this approach: if (input != null) { // do stuff } As far as I know, you can't redefine null, so it's not going to break unexpectedly. And, because of the type-coercion of the != operator, this checks for both undefined and null... which is often exactly what you want (e.g. for optional function parameters). Yet this form does not seem widespread, and it even causes JSLint to yell at you for using the evil != operator. Why is this considered bad style?
