  • how can I get instance from the property.

    - by viky
    In my application I have a class which has properties of user-defined types like this: class MyType { public A MyProperty { get; set; } } class A { .....some methods and proeprties } for some operations that I need to perform from my main program, I create a List of MyProperty whenever creating object of MyType and pass it to my main program and there I perform different operation on these properties which reflects in there instances also. Is there any way by which I could get the object instance for any particular MyProperty from that property in the list.

  • Database Schema for Machine Tags?

    - by Gabriel
    Machine tags are more precise tags: http://www.flickr.com/groups/api/discuss/72157594497877875. They allow a user to basically tag anything as an object in the format object:property=value Any tips on a rdbms schema that implements this? Just wondering if anyone has already dabbled with this. I imagine the schema is quite similar to implementing rdf triples in a rdbms

  • Special chars in Amazon S3 keys?

    - by Martin
    Is it possible to have special characters like åäö in the key? If i urlencode the key before storing it works, but i cant really find a way to access the object.

Is there some way to do this?

  • VB.NET: question about "using" block

    - by Craig Johnston
    Consider the code: On Error Goto ErrorHandler Using sr As StreamReader = New StreamReader(OpenFile) str = sr.ReadToEnd sr.Close() End Using Exit Sub ErrorHandler: If there is an error inside the Using block how do you clean up the sr object? The sr object is not in scope in ErrHandler so sr.Close() cannot be called. Does the Using block cleanup any resources automatically even if there is an error?

  • Control serialization of GWT

    - by Phuong Nguyen de ManCity fan
    I want GWT to not serialize some fields of my object (which implements Serializable interface). Normally, transient keyword would be enough. However, I also need to put the object on memcache. The use of transient keyword would make the field not being stored on memcache also. Is there any GWT-specific technique to tell the serializer to not serialize a field?

  • finding and returning a string with a specified prefix

    - by tipu
    I am close but I am not sure what to do with the restuling match object. If I do p = re.search('[/@.* /]', str) I'll get any words that start with @ and end up with a space. This is what I want. However this returns a Match object that I dont' know what to do with. What's the most computationally efficient way of finding and returning a string which is prefixed with a @? For example, "Hi there @guy" After doing the proper calculations, I would be returned guy

  • Can sorting Japanese kanji words be done programatically?

    - by Mason
    I've recently discovered, to my astonishment (having never really thought about it before), machine-sorting Japanese proper nouns is apparently not possible. I work on an application that must allow the user to select a hospital from a 3-menu interface. The first menu is Prefecture, the second is City Name, and the third is Hospital. Each menu should be sorted, as you might expect, so the user can find what they want in the menu. Let me outline what I have found, as preamble to my question: The expected sort order for Japanese words is based on their pronunciation. Kanji do not have an inherent order (there are tens of thousands of Kanji in use), but the Japanese phonetic syllabaries do have an order: ???????????????????... and on for the fifty traditional distinct sounds (a few of which are obsolete in modern Japanese). This sort order is called ???? (gojuu on jun , or '50-sound order'). Therefore, Kanji words should be sorted in the same order as they would be if they were written in hiragana. (You can represent any kanji word in phonetic hiragana in Japanese.) The kicker: there is no canonical way to determine the pronunciation of a given word written in kanji. You never know. Some kanji have ten or more different pronunciations, depending on the word. Many common words are in the dictionary, and I could probably hack together a way to look them up from one of the free dictionary databases, but proper nouns (e.g. hospital names) are not in the dictionary. So, in my application, I have a list of every prefecture, city, and hospital in Japan. In order to sort these lists, which is a requirement, I need a matching list of each of these names in phonetic form (kana). I can't come up with anything other than paying somebody fluent in Japanese (I'm only so-so) to manually transcribe them. Before I do so though: Is it possible that I am totally high on fire, and there actually is some way to do this sorting without creating my own mappings of kanji words to phonetic readings, that I have somehow overlooked? Is there a publicly available mapping of prefecture/city names, from the government or something? That would reduce the manual mapping I'd need to do to only hospital names. Does anybody have any other advice on how to approach this problem? Any programming language is fine--I'm working with Ruby on Rails but I would be delighted if I could just write a program that would take the kanji input (say 40,000 proper nouns) and then output the phonetic representations as data that I could import into my Rails app. ??????????

  • What are the 'big' advantages to have Poco with ORM?

    - by bonefisher
    One advantage that comes to my mind is, if you use Poco classes for Orm mapping, you can easily switch from one ORM to another, if both support Poco. Having an ORM with no Poco support, e.g. mappings are done with attributes like the DataObjects.Net Orm, is not an issue for me, as also with Poco-supported Orms and theirs generated proxy entities, you have to be aware that entities are actually DAO objects bound to some context/session, e.g. serializing is a problem, etc..

  • Objective-C retain counts in dealloc

    - by Michael Waterfall
    I'm seeing something fairly strange here, I've got breakpoints set in various dealloc methods in my app, and on inspection, the retain counts of the object self varies from 1 to 0. When dealloc is called, will the retain count of the object be set to 0 already? I'm using print (int) [self retainCount] in the console to test this. The 0's seem to only appear in the dealloc of my NSOperation's that are being run in an NSOperationQueue. Any idea why this is?

  • [Flex] Caching canvas into ByteArray

    - by Eugene
    Task: (all in code, not visual) create a canvas, place into it some labels and draw some lines, then cache it as byteArray. The problem is that if I cache an object that is already drawed on the screen, it works great, but if I cache a canvas, that have been created few lines earlier, this results white image. Is there any solution to cache a display object, that was created in code, but not intended to be displayed at all?
