  • C# How to create objects without class definitions?

    - by JL
    Is it possible to create objects at designtime without having to have hard coded class definitions, then populate properties with primitives or even strongly typed data types? This might sound confusing, so I will attempt to give you a use case scenario. Use case: You have an XML config file that could hold configuration values for connecting to various systems in an SOA application. In C# the XML file is read, but for each system the configuration properties are different (e.g: SQL might have a connection string, while SharePoint might need a username + password + domain + url, while yet an smtp server would need username + password + port + url) So instead of creating static classes as follows public class SharePointConfiguration or public class SQLConfiguration, then have each class with custom properties (this is cumbersome) or using a 1990's method, an arrayList or some named collection Is there not a more preferred way to achieve this? Taking advantage of new language features, that can still offer design time intellisense, which would make the code easier to maintain and less prone to error. Thanks

  • Hiding text under an image for SEO purposes

    - by JCHASE11
    I am going to use a large image on my page with a bunch of text on it. The reason I am including body text on an image is because the text will be rotated, and there currently isn't any GREAT solution for rotating text seamlessly across all browsers. On this image, there is a lot of text, and I want it to be indexed by search engines. (but its a picture so it's content won't be indexed, obviously) If I was to include a div with all the text html and set the css to display:none, would Google still index the content that is hidden under the picture? Are their any other solid solutions here?

  • When using Dependency Injection with StructureMap how do I chooose among multiple constructors?

    - by Mark Rogers
    I'm trying to get structuremap to build Fluent Nhibernate's SessionSource object for some of my intregration tests. The only problem is that Fluent's concrete implementation of ISessionSource (SessionSource) has 3 constructors: public SessionSource(PersistenceModel model) { Initialize(new Configuration().Configure(), model); } public SessionSource(IDictionary<string, string> properties, PersistenceModel model) { Initialize(new Configuration().AddProperties(properties), model); } public SessionSource(FluentConfiguration config) { configuration = config.Configuration; sessionFactory = config.BuildSessionFactory(); dialect = Dialect.GetDialect(configuration.Properties); } I've tried configuring my ObjectFactory supplying an argument for the first constructor but it seems like it wants to try the second one. How do I configure my ObjectFactory so that I can choose the first constructor or perhaps even another one if I decide to use that?

  • VBScript: how to set values from recordset to string

    - by phill
    This is probably a beginner question, but how do you set a recordset to a string variable? Here is my code: Function getOffice (strname, uname) strEmail = uname WScript.Echo "email: " & strEmail Dim objRoot : Set objRoot = GetObject("LDAP://RootDSE") Dim objDomain : Set objDomain = GetObject("LDAP://" & objRoot.Get("defaultNamingContext")) Dim cn : Set cn = CreateObject("ADODB.Connection") Dim cmd : Set cmd = CreateObject("ADODB.Command") cn.Provider = "ADsDSOObject" cn.Open "Active Directory Provider" Set cmd.ActiveConnection = cn cmd.CommandText = "SELECT physicalDeliveryOfficeName FROM '" & objDomain.ADsPath & "' WHERE mail='" & strEmail & "'" cmd.Properties("Page Size") = 1 cmd.Properties("Timeout") = 300 cmd.Properties("Searchscope") = ADS_SCOPE_SUBTREE Dim objRS : Set objRS = cmd.Execute WScript.Echo objRS.Fields(0) Set cmd = Nothing Set cn = Nothing Set objDomain = Nothing Set objRoot = Nothing Dim arStore Set getOffice = objRS.Fields(0) Set objRS = Nothing End function When I try to run the function, it throws an error "vbscript runtime error: Type mismatch" I presume this means it can't set the string variable with a recordset value. How do I fix this problem?

  • Spring @Value annotation not using defaults when property is not present

    - by garyj
    Hi All I am trying to use @Value annotation in the parameters of a constructor as follows: @Autowired public StringEncryptor( @Value("${encryptor.password:\"\"}") String password, @Value("${encryptor.algorithm:\"PBEWithMD5AndTripleDES\"}") String algorithm, @Value("${encryptor.poolSize:10}") Integer poolSize, @Value("${encryptor.salt:\"\"}") String salt) { ... } When the properties file is present on the classpath, the properties are loaded perfectly and the test executes fine. However when I remove the properties file from the classpath, I would have expected that the default values would have been used, for example poolSize would be set to 10 or algorithm to PBEWithMD5AndTripleDES however this is not the case. Running the code through a debugger (which would only work after changing @Value("${encryptor.poolSize:10}") Integer poolSize to @Value("${encryptor.poolSize:10}") String poolSize as it was causing NumberFormatExceptions) I find that the defaults are not being set and the parameters are in the form of: poolSize = ${encryptor.poolSize:10} or algorithm = ${encryptor.algorithm:"PBEWithMD5AndTripleDES"} rather than the expected poolSize = 10 or algorithm = "PBEWithMD5AndTripleDES" Based on SPR-4785 the notation such as ${my.property:myDefaultValue} should work. Yet it's not happening for me! Thank you

  • What are "named tuples" in Python?

    - by Denilson Sá
    Reading the changes in Python 3.1, I found something... unexpected: The sys.version_info tuple is now a named tuple: I never heard about named tuples before, and I thought elements could either be indexed by numbers (like in tuples and lists) or by keys (like in dicts). I never expected they could be indexed both ways. Thus, my questions are: What are named tuples? How to use them? Why/when should I use named tuples instead of normal tuples? Why/when should I use normal tuples instead of named tuples? Is there any kind of "named list" (a mutable version of the named tuple)?

  • controlling the order of submitted futures

    - by mac
    In this example, i am submitting a few files to my comparator object. It all works fine, except that i noticed that order in which files are submitted is not always teh same order in which they are returned. Any suggestions on how i can better control this? ExecutorService pool = Executors.newFixedThreadPool(5); CompletionService<Properties> completion = new ExecutorCompletionService<Properties>(pool); for (String target : p.getTargetFiles()) { completion.submit(new PropertiesLoader(target, p)); } for (@SuppressWarnings("unused") String target : p.getTargetFiles()) { Properties r = null; try { r = completion.take().get(); } catch (InterruptedException e) { e.printStackTrace(); } catch (ExecutionException e) { e.printStackTrace(); } p.addTargetFilesProperties(r); } pool.shutdown();

  • C# - .WAV Playback Randomly High Pitch

    - by Nate Shoffner
    For some reason, when a WAV file is played back using the snippet below, it randomly plays back screwy, like a high pitch noise. It doesn't happen all the time, just randomly. It seems to happen more often when it is played back more frequently. The WAV properties are below along with the code snippet I am using. WAV Properties: Bit Rate - 750kbps Audio Sample Size - 16 bit Channels - 1 (mono) Audio Sample Rate - 44kHz Audio Format - PCM Snippet: System.Media.SoundPlayer myPlayer = new System.Media.SoundPlayer(Captcha.Properties.Resources.sound1); myPlayer.Play(); Is this because of the way I am playing the file or the file itself? Thank you.

  • Adding more OR searches with CONTAINS Brings Query to Crawl

    - by scolja
    I have a simple query that relies on two full-text indexed tables, but it runs extremely slow when I have the CONTAINS combined with any additional OR search. As seen in the execution plan, the two full text searches crush the performance. If I query with just 1 of the CONTAINS, or neither, the query is sub-second, but the moment you add OR into the mix the query becomes ill-fated. The two tables are nothing special, they're not overly wide (42 cols in one, 21 in the other; maybe 10 cols are FT indexed in each) or even contain very many records (36k recs in the biggest of the two). I was able to solve the performance by splitting the two CONTAINS searches into their own SELECT queries and then UNION the three together. Is this UNION workaround my only hope? Thanks. SELECT a.CollectionID FROM collections a INNER JOIN determinations b ON a.CollectionID = b.CollectionID WHERE a.CollrTeam_Text LIKE '%fa%' OR CONTAINS(a.*, '"*fa*"') OR CONTAINS(b.*, '"*fa*"') Execution Plan (guess I need more reputation before I can post the image):

  • Does Oracle 11g automatically index fields frequently used for full table scans?

    - by gustafc
    I have an app using an Oracle 11g database. I have a fairly large table (~50k rows) which I query thus: SELECT omg, ponies FROM table WHERE x = 4 Field x was not indexed, I discovered. This query happens a lot, but the thing is that the performance wasn't too bad. Adding an index on x did make the queries approximately twice as fast, which is far less than I expected. On, say, MySQL, it would've made the query ten times faster, at the very least. I'm suspecting Oracle adds some kind of automatic index when it detects that I query a non-indexed field often. Am I correct? I can find nothing even implying this in the docs.

  • Any way to avoid a filesort when order by is different to where clause?

    - by Julian
    I have an incredibly simple query (table type InnoDb) and EXPLAIN says that MySQL must do an extra pass to find out how to retrieve the rows in sorted order. SELECT * FROM `comments` WHERE (commentable_id = 1976) ORDER BY created_at desc LIMIT 0, 5 exact explain output: table select_type type extra possible_keys key key length ref rows comments simple ref using where; using filesort common_lookups common_lookups 5 const 89 commentable_id is indexed. Comments has nothing trick in it, just a content field. The manual suggests that if the order by is different to the where, there is no way filesort can be avoided. http://dev.mysql.com/doc/refman/5.0/en/order-by-optimization.html I also tried order by id as well as it's equivalent but makes no difference, even if I add id as an index (which I understand is not required as id is indexed implicitly in MySQL). thanks in advance for any ideas!

  • BeanUtils getPropertyOfMapBean

    - by dx-cp
    Hi, Im wondering if it is possible to get data from property which is map cotaining pairs Key-StringArray (Map) in BeanUtils library. I just simply need to access one of array elements by calling propertyName=string[0]. Current version (1.8.3) does not support indexed properties. If you look into their code you will find in class PropertyUtilsBean in method getPropertyOfMapBean: if (resolver.isIndexed(propertyName) || resolver.isMapped(propertyName)) { throw new IllegalArgumentException( "Indexed or mapped properties are not supported on" + " objects of type Map: " + propertyName); } way too bad:-( Have any of you any tip how to do it somehow differently?

  • how to create a auto-incremented attribute in xcode managed object model

    - by Mausimo
    Hey, what i want to do is to make a int that will be the ID of the entity and auto increment itself whenever a new entity is added (just like a SQL identity property). Is this possible? i tried using indexed (checked on attribute) however there is no description to what indexed even does. EDIT: I am adding annotations to a map, when you click the pin the annotationview with a chevron shows up. Now when you click this button i would like to load an associated picture. However the only way i know how to link the picture to this button is to give the picture a unique id, and then set the button.tag to this id and then load based on the button.tag.

  • How to map it? HasOne x References

    - by Felipe
    Hi everyones, I need to make a mapping One by One, and I have some doubts. I have this classes: public class DocumentType { public virtual int Id { get; set; } /* othes properties for documenttype */ public virtual DocumentConfiguration Configuration { get; set; } public DocumentType () { } } public class DocumentConfiguration { public virtual int Id { get; set; } /* some other properties for configuration */ public virtual DocumentType Type { get; set; } public DocumentConfiguration () { } } A DocumentType object has only one DocumentConfiguration, but it is not a inherits, it's only one by one and unique, to separate properties. How should be my mappings in this case ? Should I use References or HasOne ? Someone could give an example ? When I load a DocumentType object I'd like to auto load the property Configuration (in documentType). Thanks a lot guys! Cheers

  • Obtain all keys of a Neo4j index

    - by MattiSG
    I have a Neo4j database whose content is generated dynamically from a big dataset. All “entry points” nodes are indexed on a named index (IndexManager.forNodes(…)). I can therefore look up a particular “entry point” node. However, I would now like to enumerate all those specific nodes, but I can't know on which key they were indexed. Is there any way to enumerate all keys of a Neo4j Index? If not, what would be the best way to store those keys, a data type that is eminently non-graph-oriented? UPDATE (thanks for asking details :) ): the list would be more than 2 million entries. The main use case would be to never update it after an initialization step, but other use cases might need it, so it has to be somewhat scalable. Also, I would really prefer avoiding killing my current resilience abilities, so storing all keys at once, as opposed to adding them incrementally, would be a last-resort solution.

  • SEO URL Structure

    - by Neil
    Based on the following example URL structure: mysite.com/mypage.aspx?a=red&b=green&c=blue Pages in the application use ASP.net user controls and some of these controls build a query string. To prevent duplicate keys being created e.g. &pid=12&pid=10, I am researching methods of rewriting the URL: a) mysite.com/mypage.aspx/red/green/blue b) mysite.com/mypage.aspx?controlname=a,red|b,green|c,blue Pages using this structure would be publishing content that I would like to get indexed and ranked - articles and products (8,000 products to start, with thousands more being added later) My gut instinct tells me to go with the first method, but would it would be overkill to add all that infrastructure if the second method will accomplish my goal of getting pages indexed AND ranked. So my question, looking at the pro's and con's, Google Ranking, time to implement etc. which method should I use? Thanks!

  • full-text property change on column

    - by matt99
    Hello, i'm trying to modify a property of a column (in sql server 2008 r2) which is of xml data type. I want set (Is full-text indexed) to yes, but after I do this and try to save changes, i get an error: 'Abc' table - Unable to modify table. Column: B is not full-text searchable. Column B is not the column I'm modyfing, but it's content is based on the modified xml column (it takes a value from one element in xml). Weird thing is that column B is full-text indexed (in table designer). Any ideas why i cannot apply changes to the xml column?

  • Localizing a JSF 1.2 application with UTF-8 resources

    - by Filini
    (WARNING: this is my first java application, coming from .NET, so don't bash me if I write too much garbage) I'm developing a simple JSF 1.2 web application which should support Russian, Chinese, and other languages outside ISO 8859-1, which is automatically used in Properties.load(). Is there a way to use the Properties loaded from XML files, with Properties.loadFromXml(), inside JSF, without writing too much code? I know there are alternative ways to do so (writing my own loader, escaping the characters...), but I'd really love to find a simple solution, and I don't see it in all the forums I checked. Thanks in advance for any help

  • App.Config file in console application C#

    - by user1240679
    I have a console application in which I want to write the name of a file. Process.Start("blah.bat"); Normally, I would have something like that in windows application by writing the name of the file 'blah.bat' to Settings file in Properties. However, here I didn't find any Settings file and I added an app.config for the same purpose. I am not sure what to write here in app.config, that would lead to me to achieve similar thing as in windows forms. For eg: In windows forms. Process.Start(Properties.Settings.Default.BatchFile); where BatchFile is a string in settings file in Properties.

  • Confusion over manual/automatic sizing of Flash Sprite Objects

    - by John
    If I have a custom class subclassing Sprite and it draws some simple objects, how does this work with respect to the Sprite.width & Sprite.height properties? It seems I can draw (for example) a rectangle of any size, bigger than the Sprite size. Similarly if I set the width/height properties, what happens to the content already drawn? As a use-case, I might have a stick-man which is drawn as a set of lines, I want to set the man's height and the rendering is scaled to this. Are there any issues with width/height being auto-calculated or am I misunderstanding what these properties actually mean?

  • How do I instantiate Class Dynamically in Java?

How do I load a Java Class that is not compiled?

  • Specifying Locations relative to the context XML in Spring

    Is there a way to reference a properties file relative to the Spring's context file itself?

Thanks.

  • Ojective C Class or struct?

    - by Scott Pendleton
    I have a class Song with properties Title, Key, Artist, etc. There are no methods. I loop through a database of song information and create a Song object for each, populating the properties, and then store the Song objects in an NSArray. Then I thought, why not just have a struct Song with all those same properties instead of a class Song. Doing so would eliminate the class files, the #import Song line in the using class's .m file, and the need to alloc, init, release. On the other hand, I'd have to put the struct definition in every class that might need it. (Unless there's some globally accessible location -- is there?) Also, can a struct be stored in an NSArray?

  • Adding interfaces that won't be actually used

    - by devoured elysium
    I currently have two interfaces(that I'll name here IA and IB): interface IA { int Width; int Height; ... } interface IB { int Width; int Height; ... } that share the same two properties: they both have a Width and a Height property. I was thinking if there is any point in defining an IMatrix interface containing a Width and Height properties: interface IMatrix { int Width; int Height; } The thing is that although they share both the same properties, I won't make use of polymorphism with IMatrix in any of my coding: i.e., there won't by any situation where I'll want to use an IMatrix, I'll just want to use IA and IB. Adding an IMatrix seems more like over-engineering than other thing, but I'd like to ask you guys what your opinion is on the matter. Thanks
