• Can't get a List(Of <my class>) from a Dictionary in .NET?

  - by magsto

  I have a Dictionary with key of type UInteger and the value is List(Of Session) where the (Public) class Session contains a couple of variables and a constructor (Public Sub New(...)). Some of the variables in my Session class is: Private count As Integer Private StartDate As Date Private Values As List(Of Integer) and a couple of methods like: Friend Sub Counter(ByVal c as Integer) count += c End Sub There is no problem to add values to the Dictionary: Dim Sessions As New List(Of Session) Dim dict As New Dictionary(Of Integer, Sessions) then some code to fill up a couple of Session objects in Sessions (not shown here) and then: dict.Add(17, Sessions) 'No problem Sessions.Clear() Sessions = dict(17) 'This doesn't return anything! The Sessions object is empty even if the code doesn't returned any error. Is my class Session to compex to be stored in a Dictionary?

• how to add multiple markers to mapview in android?

  - by Vishakha Kinjawadekar

  I am working on android geolocation application in that I have added marker for current location and want to add markers for other geopoints also. I have created objects of OverlayItem for other points and adding it to ItemizedOverlay like itemizedOverlay.addOverlay(overlayItem) and then adding it to mapOverlay.add(itemizedOverlay). For the current location geopoints getting from "Location" object and other points are hard-coded values. After executing it only current location marker is displayed not the other hardcoded points.How can I add marker for these geopoints and where? Thanks , Vishakha.

• Count function calls by name or signature. Gcc, C++

  - by MajesticRa

  I have some c++ written package. Linux, gcc. I can modify compilation process (change Makefile, flags, etc.), but can not change C++ source code. One runs the package with different parameters, it does a job and exits. How to count: 1) Number of calls of function with specific name? 2) Number of calls of functions with specific signature? 3) Number of calls of functions where one of the parameters is of specific type i.e. std::string (type is specified by signature)? 4) and extra Number of calls of functions of STL objects, i.e. std::string copy constructor? (I mean count a number of calls during the run. ) I thought to do it with GDB, but I found it very tough to do (1) and have not found how to do (2)-(4) at all. All acceptable answers I will write here for humanity.

• Tag suggestion (not tag autocomplete)

  - by takeshin

  AJAX autocomplete is fairly simple to implement. However, I wonder how to handle smart tag suggestion like this on SO. To clarify the difference between autocomplete and suggestion: autocomplete: foo [foobar, foobaz] suggestion: foo [barfoo, foobar, foobaz], or even better, with 'did you mean' feature: [barfoo, foobar, foobaz, fobar, fobaz] I suppose I need some full text search in tags (all letters indexed, not just words). There would be no problem to do it witch regex or other patterns for limited number of tags (even client side). But how to implement this feature for big number of tags? Is there any particular reason (besides URL) the tags on SO are dash separated? What about Unicode characters in tags? I store the tags in the table with the following columns: id, tagname. My SQL query returns objects with following fields: id, tagname, count

• Passing Session[] and Request[] to Methods in C#

  - by NYARROW

  In C#, How do you pass the Session[] and Request[] objects to a method? I would like to use a method to parse out Session and Request paramaters for a .aspx page to reduce the size of my Page_Load method. I am passing quite a few variables, and need to support both POSTand GET methods. For most calls, not all variables are present, so I have to test every variable multiple ways, and the code gets long... This is what I am trying to do, but I can't seem to properly identify the Session and Request paramaters (this code will not compile, because the arrays are indexed by number) static string getParam( System.Web.SessionState.HttpSessionState[] Session, System.Web.HttpRequest[] Request, string id) { string rslt = ""; try { rslt = Session[id].ToString(); } catch { try { rslt = Request[id].ToString(); } catch { } } return rslt; } From Page_Load, I want to call this method as follows to retrieve the "MODE" paramater: string rslt; rslt = getParam(Session, Request, "MODE"); Thanks!

• Recommand a Perl module to persist a large object for re-use between runs?

  - by Alnitak

  I've got a large XML file, which takes 40+ seconds to parse with XML::Simple. I'd like to be able to cache the resulting parsed object so that on the next run I can just retrieve the parsed object and not reparse the whole file. I've looked at using Data::Dumper but the documentation is a bit lacking on how to store and retrieve its output from disk files. Other classes I've looked at (e.g. Cache::Cache) appear designed for storage of many small objects, not a single large one. Can anyone recommend a module designed for this?

• Django store regular expression in DB which then gets evaluated on page

  - by John

  Hi, I want to store a number of url patterns in my django model which a user can provide parameters to which will create a url. For example I might store these 3 urls in my db where %s is the variable parameter provided by the user: www.thisissomewebsite.com?param=%s www.anotherurl/%s/ www.lastexample.co.uk?param1=%s&fixedparam=2 As you can see from these examples the parameter can appear anywhere in the string and not in a fixed position. I have 2 models, one holds the urls and one holds the variables: class URLPatterns(models.Model): pattern = models.CharField(max_length=255) class URLVariables(models.Model): pattern = models.ForeignKey(URLPatterns) param = models.CharField(max_length=255) What would be the best way to generate these urls by replacing the %s with the variable in the database. would it just be a simple replace on the string e.g: urlvariable = URLVariable.objects.get(pk=1) pattern = url.pattern url = pattern.replace("%s", urlvariable.param) or is there a better way? Thanks

• Is map/collection order stable between calls?

  - by John

  If I have a hash map and iterate over the objects repeatedly, is it correct that I'm not guaranteed the same order for every call? For example, could the following print two lines that differ from each other: Map<String,Integer> map = new HashMap<String,Integer>() {{ put("a", 1); put("b", 2); put("c", 3); }}; System.out.println(map); System.out.println(map); And is this the case for sets and collections in general? If so, what's the best way in case you have to iterate twice over the same collection in the same order (regardless of what order that is)? I guess converting to a list.

• formatting european characters from JSON results

  - by mlecho

  hi, i am building an application that imports JSON results and parses the objects to a table cell. Nothing fancy, but in my results, many of the terms/names are European with characters such as è or ú which come out as \u00E9 or \u00FA. I think these are ASCII ? or unicode? ( i can never keep em staight). Anyway, like all good NSSTring's, i figured there must be a method to fix this, but i am not finding it....any ideas? I am trying to avoid doing something like this: this posting. Thanks all.

• Trying to re-create UI object from the native iPhone Calendar Notes

  - by FrankOS

  Probably a lame question for a start but i'm trying to re-create the ui object that's used in Apple's native Calendar to create notes. It's the basic text-field but with multiple lines. Sort of a text-area. Now i know that anything from the calendar in terms of ui objects isn't available but i have seen this in quite few apps so i'm guessing it's some sort of standard component. I must be dumb but i just cannot find it. Help please... Thx :)

• Python: UTF-8 problems (again...)

  - by blahblah

  I have a database which is synchronized against an external web source twice a day. This web source contains a bunch of entries, which have names and some extra information about these names. Some of these names are silly and I want to rename them when inserting them into my own database. To rename these silly names, I have a standard dictionary as such: RENAME_TABLE = { "Wsird" : "Weird", ... } As you can see, this is where UTF-8 comes into play. This is the function which performs renaming of all the problematic entries: def rename_all_entries(): all_keys = RENAME_TABLE.keys() entries = Entry.objects.filter(name__in=all_keys) for entry in entries: entry.name = RENAME_TABLE[entry.name] entry.save() So it tries to find the old name in RENAME_TABLE and renames the entry if found. However, I get a KeyError exception when using RENAME_TABLE[entry.name]. Now I'm lost, what do I do? I have... # -*- coding: utf-8 -*- ...in the top of the Python file.

• Calling inheriting class methods via interface.

  - by Stacey

  Given the scenario... interface IBase{ void Process(int value); } abstract class Base : IBase { public virtual void Process(int value){ throw new NotImplementedException(); } } class Implemented: Base, IBase { public void Process(int value) { // .. some code here.. } } I'm trying to write a loop similar to the following. foreach( Base b in CollectionOfImplemented ) { b.Process( // something will go here // ); } Trying this, it keeps calling Base.Process, instead of Implemented.Process; but the type in the collection is Implemented, not Base. Boxing it seems to work, but I was hoping to see if I could find a more intelligent approach to it, since the Collection will contain other types of objects that also inherit from Base.

• EntityFramework 4.0: can you return different types depending on data in the database?

  - by user200341

  I have a Media table in the database. I also have an IMedia interface. I have two different media types that implements the same interface: 1) AudioMedia 2) PictureMedia What I wonder here, is if I can use EntityFramework (I'm using an EDMX file but I have my models in a separate library, with automatic code generation turned off), and depending on the data in the database, select what type to get (AutioMedia or PictureMedia). Since they are both implementing the same interface (could be changed to an abstract class if needed I suppose), I'm thinking that somewhere along the way you could specify what class it should be. I should perhaps point out that I have a class that inherits from ObjectContext to access the objects. Perhaps there is something that that can be done?

• finding last loop through a jQuery object

  - by DA

  Sample jquery. Assume $cog is a cached selector of multiple items. $cog.fadeOut('slow',function(){ alert('hey'); }) In that example, of $cog is a jQuery object of 4 DOM elements, the above will fade each element out one by one, and trigger an alert each time on the callback (4 alerts). I'd like to only call the alert when all 4 elements are done with their fadeOut function. This: $cog.fadeOut('slow',function(){ }) alert('hey'); when run, will show an alert, then the $cog elements disappear (I'm guessing due to timing issues with the fadeOut animation) Is there a way when calling a function against multiple DOM objects in a jQuery object to know when it's done with the last item?

• Core Data-Linking one-to-many relationships

  - by Stelmate

  I have a one-to-many relationship where each department has many employees. When I create a new employee object I just link it to the parent department manually by setting the property to the instance of the department I have fetched from my fetch request. However, this seems to be improper because when I try to access the set of employees from the department by simply accessing the .employees property on my department object instance it returns a 0 count. Isn't the fault suppose to fire once I access a property? Am I linking my parent/child objects incorrectly?

• Delphi Memory Management

  - by nomad311

  I haven't been able to find the answers to a couple of my Delphi memory management questions. I could test different scenarios (which I did to find out what breaks the FreeAndNil method), but its takes too long and its hard! But seriously, I would also like to know how you all (Delphi developers) handle these memory management issues. My Questions (Feel free to pose your own I'm sure the answers to them will help me too): Does FreeAndNil work for COM objects? My thoughts are I don't need it, but if all I need to do is set it to nil than why not stay consistent in my finally block and use FreeAndNil for everything? Whats the proper way to clean up static arrays (myArr : Array[0..5] of TObject). I can't FreeAndNil it, so is it good enough to just set it to nil (do I need to do that after I've FreeAnNil'd each object?)? Thanks Guys!

• Changing the value of a macro at run time

  - by BrandiNo

  I'm working in Visual Studio 2010, using C++ code. What I'm trying to do is change the value of a preprocessor directive during run time, not sure if it's possible but i've tried this.. somefile.h static int mValue = 0; #define POO = mValue; ... #if POO 0 //define class methods #else //define class methods differently } main.cpp main() { //Code calls constructor and methods allowed when POO is 0 //Code increments mValue //Code calls constructor and methods allowed when POO is 1 } How can POO be changed so that class objects uses a different implementation of other methods? Or if it's not possible, what's a another approach to this?

• Any way to not break on certain errors in Visual Studio 2010?

  - by Vulgrin

  I'm working on a VS2010 project where I'm using DataAnnotations on my objects to handle validation. However, this is sort of a pain in the butt while trying to do interactive debugging because it keeps pausing VS.Net on validation errors. Obviously, I want to break on some errors, but not these particular types. Am I out of luck and I just need to turn on and off my Break on All Errors setting? Or is there some way to tell VS to just ignore these when they happen? (these are errors generated via Validator.ValidateProperty calls.) Thanks

Guide me with the best way of doing it..

• Java synchronizing static list ?

  - by JavaUser

  Hi, In a Java class , i am having a static list so this list is shared across all the objects of this class.The business logic in this class will run periodically which is invoked by some method with out passing instance parameters.Now I want to invoke this run method based on the list(I will add some vales into this list based on JMS) ,this list may empty sometimes and after finishing the run , i am emptying this list.Now my question is , whether I need to synchronize this list or not? Also let me know is there any other way to pass value in one object instance(Thread1) to other object instance (Thread2) other than having Static variable(static list)? Thx

• How to manage memory for ios with large csv files?

  - by Pell000

  I'm new to ios development, and I'm running into issues relating to memory management and my approaches to dealing with large datasets. Right now, I am loading the csv files and storing the relevant data as objects in memory at app initialization. Some of the csv files are larger than 1MB, and in total, my app uses about 180MB of memory. This is obviously way too high of a number (unless the info I found is wrong and this is an acceptable number, then please let me know). I feel as though there is a fundamental flaw in my approach: is there a way I can avoid storing the csv files in the project itself? Or, is there a kind of "lazy" loading I can do so that I can simply look up info in the csv file, as opposed to loading all of the data from it at once? Any help would do. I think that I need a new perspective in how to manage this more efficiently.

• Easy way to cast an object array into another type in C#

  - by Na7coldwater

  I want to be able to be able to quickly cast an array of objects to a different type, such as String, but the following code doesn't work: String[] a = new String[2]; a[0] = "Hello"; a[1] = "World"; ArrayList b = new ArrayList(a); String[] c = (String[]) b.ToArray(); And I don't want to have to do this: String[] a = new String[2]; a[0] = "Hello"; a[1] = "World"; ArrayList b = new ArrayList(a); Object[] temp = b.ToArray(); Object[] temp = b.ToArray(); String[] c = new String[temp.Length]; for(int i=0;i<temp.Length;i++) { c[i] = (String) temp[i]; } Is there an easy way to do this without using a temporary variable?

• What does -setPropagatesDeletesAtEndOfEvent: actually do?

  - by dontWatchMyProfile

  Let me try it: If I don't set this, then the default value is YES. So when I delete an managed object from the context, the context propagates this immediately to the persistent store so the object is gone? And when I set this to NO, then objects are deleted from the persistent store only when calling -save? Is that really true? I mean: If it was true, then the default behavior is that once you call the context to delete an object, the object is gone. Lets assume you're not using an undo manager. So... gone. Right? No rollback possible? Or can it still be recovered with a rollback?

• A generic list of generics

  - by SnOrfus

  I'm trying to store a list of generic objects in a generic list, but I'm having difficulty declaring it. My object looks like: public class Field<T> { public string Name { get; set; } public string Description { get; set; } public T Value { get; set; } /* ... */ } I'd like to create a list of these. My problem is that each object in the list can have a separate type, so that the populated list could contain something like this: { Field<DateTime>, Field<int>, Field<double>, Field<DateTime> } So how do I declare that? List<Field<?>> (I'd like to stay as typesafe as possible, so I don't want to use an ArrayList).

• Websphere/Oracle 11 - much more Heap Usage than with Oracle 10

  - by swalkner

  Hi all, while testing our application with Oracle 11 (previously, we had Oracle 10), we saw that our server uses much more heap space. It seems as it has something to do with T4CConnection; there are 500 objects of T4CConnection allocated. Someone told me, that Oracle 11 is using SoftReferences to keep the connection pool; but we don't need that. Is that correct? Could that be the problem for the increased heap space? If yes - how can we avoid connection pooling? Thanks a lot!!
