• Neat way of gettings position of my Object in linq collections

  - by Steve

  I currently have a object called Week. A week is part of a Season object. the season can contain many weeks. What I want to do is find the position of my week (is it the first week in the season (so #1) or is it the second (so #2). int i = 0; foreach ( var w in Season.Weeks.OrderBy(w => w.WeekStarts)){ if(w.Id == Id){ return i; } i+=1; } At the moment this is what I have. I order the weeks in a second by there start date to make sure they are in the correct order. and I cycle through them until I find the week that matches the week I am currently looking at. and return the int that I have been counting up.. I feel there should be a easier linq way to do this as it feels pretty messy!

• Modifying value of "Rating" column within Explorer for arbitrary file types

  - by Fake Name

  Basically, I have a large body of assorted media (text, images, flash files, archives, folders, etc...) and I'm attempting to organize it. Windows Explorer has a rating column, but there seems to be no way to modify the rating of the files short of opening them in their type-specific software (e.g. Media player, or Photo viewer). However, this does not work when the file is of an unsupported type (.rar, .swf ...), or a directory. I'd be more than willing to consider a file-manager replacement (I've alreadly looked at quite a few, Directory Opus, Total Commander, etc...), or even a solution that stores the rating metadata in a hidden file in each folder, or a separate database. The one real critical requirement is the ability to sort by rating, and being filetype-agnostic. Basically, is there any way to categorize a large collection of assorted files by rating that will work with any file type, including directories? - Ideally, there would be an easy way to add arbitrary columns to windows explorer, and edit them directly. However, there seems to be no way to do this. The rating column is the next best thing.

• Unable to read values from object returned from ActiveRecord.find

  - by Venki

  I make the following call to the DB. @patientRegistration = PatientRegistration.find(:all, :conditions=["name = '#{patientName}'"]) Search for patient registration based on a given name. I get a valid @patientRegistration object.When I invoke @patientRegistration.inspect it prints correctly all the values for the object in the DB. But when I try to read a particular attribute (Say id or name) by doing the following: @patientRegistration.id or @patientRegistration.name. I get invalid values. Either its blank or some junk values. I dont understand how inspect is able to retrieve all the values correctly but reading individual attributes gives invalid values. Thanks

• Learning to write organized and modular programs (C++)

  - by Peter

  Hi All, I'm a computer science student, and I'm just starting to write relatively larger programs for my coursework (between 750 - 1500 lines). Up until now, it's been possible to get by with any reasonable level of modularization and object oriented design. However, now that I'm writing more complex code for my assignments I'd like to learn to write better code. Can anyone point me in the direction of some resources for learning about what sort of things to look for when designing your program's architecture so that you can make it as modularized as possible? Thank you for any help. Best, Peter

• How to match against multiple value possiblities in Excel

  - by Henno

  I have list of person names in column A. I want to display "1" in column B for names which end with either "e" or "i" or "n". If there would be only one match to test against, I would write something like: =IF( MID(A1,FIND(" ",B1)-1,1) = "e", "1", "0") In PHP I would solve that like this: echo in_array( $names[$row_number], array('e', 'i', 'n') ) ? '1' : '0'; What formula should I use in column B in Excel?

• Good code architecture for this problem?

  - by RCIX

  I am developing a space shooter game with customizable ships. You can increase the strength of any number of properties of the ship via a pair of radar charts*. Internally, i represent each ship as a subclassed SpaceObject class, which holds a ShipInfo that describes various properties of that ship. I want to develop a relatively simple API that lets me feed in a block of relative strengths (from minimum to maximum of what the radar chart allows) for all of the ship properties (some of which are simplifications of the underlying actual set of properties) and get back a ShipInfo class i can give to a PlayerShip class (that is the object that is instantiated to be a player ship). I can develop the code to do the transformations between simplified and actual properties myself, but i would like some recommendations as to what sort of architecture to provide to minimize the pain of interacting with this translator code (i.e. no methods with 5+ arguments or somesuch other nonsense). Does anyone have any ideas? *=not actually implemented yet, but that's the plan.

• Fetching JSON object from Servlet Java

  - by ChrisA

  I want to create an application that will fetch a JSON object from a servlet to deserialize it, and then use its variables to do other things. My servlet has the following code in the doPost: protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { ObjectOutputStream os; os = new ObjectOutputStream(response.getOutputStream()); String s = new String("A String"); Gson gson = new Gson(); String gsonObject= gson.toJson(s); os.writeObject(gsonObject); os.close(); } Now, while the servlet is running, I can access it via a browser, if I post same code in the doGet method, that would download a servlet file, which is not what I want. What should I use in my second application that would connect to the servlet, fetch the object, so that I can manipulate it later? Thanks in advance.

• Get nul value from one ViewController to one ViewController

  - by sovannarith

  I have 2 ViewControllers namely V1 and V2. I want to pass value from V2 to V1 but I get value 0 for countV1 in V1. I saw more questions in stackoverflow but I can't deal with this small problem. I use ARC. In V1 .h file @property(nonatomic,unsafe_unretained) int countV1; .m file @synthesize countV1; In V2 .m file int countV2 = 1; V1 *v1 = [V1 alloc] initWithNibName:@"V1" bundle:nil]; v1.countV1 = countV2;

• How to check if cell contains a value of another cell

  - by Antonio Oliveira

  Here is the scenario: On column A each cell has random text within it (names, address, account numbers, etc). Column A extends down to over 40 thousand rows. On column B I have a list of (account) numbers. Column B extends down to about 5 thousand rows. I need to filter column A to show only the rows that contain the account numbers that are part of column B. Neither column A nor B are in any specific order. I think he above scenario speaks for itself, but I can provide a quick example if needed (don't want to over complicate it).

• Scala 2.8.1 implicitly convert to java.util.List<java.util.Map<String, Object>>

  - by Ralph

  I have a Scala data structure created with the following: List(Map[String, Anyref]("a" -> someFoo, "b" -> someBar)) I would like to implicitly convert it (using scala.collection.JavaConversions or scala.collection.JavaConverters) to a java.util.List<java.util.Map<String, Object>> to be passed the a Java method that expects the latter. Is this possible? I have already created the following method that does it, but was wondering if it can be done automatically by the compiler? import scala.collection.JavaConversions._ def convertToJava(listOfMaps: List[Map[String, AnyRef]]): java.util.List[java.util.Map[String, Object]] = { asJavaList(listOfMaps.map(asJavaMap(_))) }

• What patterns exist for web application development?

  - by DaveDev

  I understand that MVC & MVP are design patterns that are commonly used for web development, as well as ASP.NET WebForms (more of an anti-pattern, really!). What other patterns are used in web application development? I'm not necessarily saying I want to learn/use new patterns just to be different - I do believe there's a lot of value in taking the conventional route - but I think it's good to know what else is out there to be able to properly understand what I'm currently working with. Thanks.

• Is the a pattern for iterating over lists held by a class (dynamicly typed OO languages)

  - by Roman A. Taycher

  If I have a class that holds one or several lists is it better to allow other classes to fetch those lists(with a getter) or to implement a doXList/eachXList type method for that list that take a function and call that function on each element of the list contained by that object. I wrote a program that did a ton of this and I hated passing around all these lists sometimes with method in class a calling method in class B to return lists contained in class C, B contains a C or multiple C's (note question is about dynamically typed OO languages languages like ruby or smalltalk) ex. (that came up in my program) on a Person class containing scheduling preferences and a scheduler class needing to access them.

• OpenGL index buffer object with additional data

  - by muksie

  I have a large set of lines, which I render from a vertex buffer object using glMultiDrawArrays(GL_LINE_STRIP, ...); This works perfectly well. Now I have lots of vertex pairs which I also have to visualize. Every pair consists of two vertices on two different lines, and the distance between the vertices is small. However, I like to have the ability to draw a line between all vertex pairs with a distance less than a certain value. What I like to have is something like a buffer object with the following structure: i1, j1, r1, i2, j2, r2, i3, j3, r3, ... where the i's and j's are indices pointing to vertices and the r's are the distances between those vertices. Thus every vertex pair is stored as a (i, j, r) tuple. Then I like to have a (vertex) shader which only draws the vertex pairs with r < SOME_VALUE as a line. So my question is, what is the best way to achieve this?

• Custom business object comparer

  - by gruber

  Hello, I need to implement mechanism that compares two business objects and return the list of differences (past value, new value, isDifferenceBetter). Because not all fields of class has to be compared and one fields need to be compared with different function then the other (sometimes < is better sometimes is better ... ) I figured out that I need to implelemnt custom attribute and give it to each field that has to be compared in this object. This attribute must have: - name - delegate or sth to point to the function which would be applied for comparision (dont know how to do it so far) So could anyone suggest me if its a good idea? Maybe any other ideas. Using attributes I would be able to use refflection to iterate through each field with attribute and invoke needed delegate. thanks for help bye

• Converting "User Shell Folders" registry value

  - by Sach

  The following registry key contains many system default folder locations. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders The value for the path of the All Users desktop, which is found there, is as follows: XP or earlier : [%ALLUSERSPROFILE%\Desktop] Vista or later: [%PUBLIC%\Desktop] Whereas the actual paths of the All User desktops, respectively, are as follows: XP or earlier : "C:\Documents and Settings\All Users\Desktop" Vista or later: "C:\Users\Public\Desktop" Now, if you use copy and paste the above registry values in Windows Explorer and hit enter it takes you to the actual folders. For example, if you paste [%PUBLIC%\Desktop] in a Windows Explorer in Vista it takes you to ["C:\Users\Public\Desktop"]. My question is this; how do I reproduce this behavior from withing a C# program? To be more specific, if I retrieve the registry value [%PUBLIC%\Desktop] from withing a C# program, which I can do easily, how do I convert it to ["C:\Users\Public\Desktop"]? Obviously I'm not looking for a string replacement, I need to do what Windows does.

• function to efficiently check a change of value in a nested hashmap

  - by zcaudate

  the motivation is for checking what has changed in a deeply nest map, kind of like a reverse of update-in. This is a simple example: (def p1 {:a {:a1 :1 :a2 :2} :b {:b1 :1 :b2 :2}}) (def p2 (update-in p1 [:a :a1] (constantly :updated)) ;; => {:a {:a1 :updated :a2 :2} ;; :b {:b1 :1 :b2 :2}} (what-changed? p1 p2) ;; => {:keys [:a :a1] :value :updated) (what-changed? p2 p1) ;; => {:keys [:a :a1] :value :2) I'm hoping that because clojure maps are persistent data-structures, there may be a smart algorithm to figure this out by looking at the underlying structure as opposed to walking through the nested maps and comparing the difference.

• Get the identity value from an insert via a .net dataset update call

  - by DeveloperMCT

  Here is some sample code that inserts a record into a db table: Dim ds As DataSet = New DataSet() da.Fill(ds, "Shippers") Dim RowDatos As DataRow RowDatos = ds.Tables("Shippers").NewRow RowDatos.Item("CompanyName") = "Serpost Peru" RowDatos.Item("Phone") = "(511) 555-5555" ds.Tables("Shippers").Rows.Add(RowDatos) Dim custCB As SqlCommandBuilder = New SqlCommandBuilder(da) da.Update(ds, "Shippers") It inserts a row in the Shippers Table, the ShippersID is a Indentity value. My question is how can i retrieve the Identity value generated when the new row is inserted in the Shippers table. I have done several web searches and the sources I've seen on the net don't answer it speccifically or go on to talk about stored procedures. Any help would be appreciated. Thanks!

• Compare two object lists with LINQ on specific property

  - by Niklas

  I have these two lists (where the Value in a SelectListItem is a bookingid): List<SelectListItem> selectedbookings; List<Booking> availableBookings; I need to find the ids from selectedBookings that are not in availableBookings. The LINQ join below will only get me the bookingids that are in availableBookings, and I'm not sure how to do it the other way around. != won't work since I'm comparing strings. results = ( from s in selectedbookings join a in availableBookings on s.bookingID.ToString() equals a.Value select s);

• JavaScript, transform object into array

  - by Šime Vidas

  I've got an object: var obj = { "Mike": 24, "Peter": 23, "Simon": 33, "Tom": 12, "Frank": 31 }; I want to create an array that holds the values of the object. The keys (key names) can be disregarded: [24, 23, 33, 12, 31] The order of the values is NOT important! One solution (obviously) would be do have a function that takes the values and puts them into an array: var arr = valuesToArray(obj); I will accept such a function as the answer. However, I would be more pleased if there would be an API function (ECMAScript, jQuery, browser-specific, ...) that could do this. Is there such a thing?
