  • C#: Basic Reflection Class

    - by Mike
    I'm trying to find a basic reflection abstract class that will generate basic information about a class. I have a template of how I would like it to work: class ThreeList<string,Type,T> { string Name {get; set;} Type Type {get; set;} T Value {get; set;} } abstract class Reflect<T> { List<ThreeList<string, Type, T> list; ReturnType MethodName() { foreach (System.Reflection.PropertyInfo prop in this.GetType().GetProperties()) { object value = prop.GetValue(this, new object[] { }); list.Add(prop.Name, prop.DeclaringType, value); } } } I'd like it to be infinitely deep, recursively calling Reflect. Something like this has to exist. I'm not really opposed to coding it myself, I just don't want to go through the hassle if its already been done.

  • How to name variables which are structs

    - by evilpie
    Hello, i often work on private projects using the WinApi, and as you might know, it has thousands of named and typedefed structs like MEMORY_BASIC_INFORMATION. I will stick to this one in my question, what still is preferred, or better when you want to name a variable of this type. Is there some kind of style guide for this case? For example if i need that variable for the VirtualQueryEx function. Some ideas: MEMORY_BASIC_INFORMATION memoryBasicInformation; MEMORY_BASIC_INFORMATION memory_basic_information; Just use the name of the struct non capitalized and with or without the underlines. MEMORY_BASIC_INFORMATION basicInformation; MEMORY_BASIC_INFORMATION information; Short form? MEMORY_BASIC_INFORMATION mbi; I often see this style, using the abbreviation of the struct name. MEMORY_BASIC_INFORMATION buffer; VirtualQueryEx defines the third parameter lpBuffer (where you pass the pointer to the struct), so using this name might be an idea, too. Cheers

  • Alternative to slip string in this scenario?

    - by MEM
    I have the following information to dynamicaly display: Product XYZ Very nice Very good Very cool Those Very nice, very good, very cool are advantages of a given product, textual, description advantages, normally display in a form of bullets. I guess that it makes no sense to store those on a separate table called advantages, because it will never be used to anything else despite display, and I fill it as too overkill. So I was thinking about creating a varchar255 field on this product table, and allow values to be inserted like: Very nice;Very good;Very cool On a free-form text input field. Then split those on a php array. My question is: Is it out there, a better approach ?

  • Regarding Creating Business application using Silverlight

    - by vijay
    Hi, We are in the conceptual phase to create a relatively medium size enterprise business product application using Silver light 4.0, Entity Framework and WCF. 1. Is it adivceable to use Silverlight 4.0 for this enterprise business application development or should we go in for MVC.NET / ASP.NET? 2. We have planned to use REST based WCF service. How complex would it be to write the information back to the REST WCF service? I appreciate and welcome your advice / suggestion. If you need any further details do let me know, i will be happy to share. Thanks in advance.

  • Customer provider Password Reset client.

    - by ProfK
    I'm looking for guidence on writing a custom password reset UI, but it must fit the Provider 'Pattern', or degrade silently to built-in defaults. E.g. my Reset Control must collect extra information, and perform differently to the standard Password Recovery Control. It must close as possible use the standard MembershipProvider interface for standard functions, and only use an extended interface for the non-standard stuff. I'd like some reading on issues such as, what must I ask the Membership Provider for, and what must I do myself. What must I tell the provider (service?) about what I do? Etc.

  • What causes Python "Interpreter not Initialized" error?

    - by ?????
    I'm now on my third full day this week of trying to get OpenCV to work with Python. (I have been trying on and off for the past 6 months). I get this error Python 2.7.1 (r271:86882M, Nov 30 2010, 10:35:34) [GCC 4.2.1 (Apple Inc. build 5664)] on darwin Type "help", "copyright", "credits" or "license" for more information. dlopen("/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/readline.so", 2); import readline # dynamically loaded from /Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload/readline.so >>> import cv dlopen("./cv.so", 2); Fatal Python error: Interpreter not initialized (version mismatch?) and then it crashes (core dumps). python -v gives nothing after the dlopen.

  • Doesn't Spring really support Interface injection at all?

    - by mrCoder
    Hi I know that Spring doesn't supports Interface injection and I've read that many a times. But today as I came across an article about IOC by Martin Fowler (link), it seems using ApplicationContextAware in Spring is some what similar to the Interface injection. when ever Spring' context reference is required in our Spring bean, we'll implement ApplicationContextAware and will implement the setApplicationContext(ApplicationContext context) method, and we'll include the bean in the config file. Is not this the same as Interface injection, where where telling the Spring to inject (or), say, pass the reference of the context into this bean? Or I m missing something here? Thanks for any information! ManiKanta

  • Update NSView in function of events

    - by Forchita
    Hi everyone! I have a main view (subclass of NSView) and as i'm new to cocoa, i'd like to know how to update the view in function of events. I know there are many methods that take events such as -(void)mouseMoved:(NSEvent*)event or - (void)mouseClicked:(NSEvent*)event My algorithm to determine what to do is ready. I want to know where I should update the main view: is it in the -(void)mouseMoved:(NSEvent*)event or in the - (void)drawRect:(NSRect)dirtyRect. And if it is in drawRect, then how should i pass the information to it? Thanks in advance!

  • How long can a hash left out in the open be considered safe?

    - by Xeoncross
    If I were to leave a SHA2 family hash out on my website - how long would it be considered safe? How long would I have before I could be sure that someone would find a collision for it and know what was hashed? I know that the amount of time would be based on the computational power of the one seeking to break it. It would also depend on the string length, but I'm curious just how secure hashes are. Since many of us run web-servers we constantly have to be prepared for the day when someone might make it all the way to the database which stores the user hashes. So, move the server security out of the way and then what do you have? This is a slightly theoretical area for many of the people I have talked with, so I would love to actually have some more information about average expectations for cracking.

  • php, extract data from a non-standard xml document

    - by Michael
    I have some kind xml content I need to extract the information and store it into database <xml file="136000000-136100000"> <Id>136000000</Id> <Name>Sem Serxy</Na me> <Email>[email protected]</Email> <DateRegistration>10/13/2010 1:49:30 AM</DateRegistration> </xml> <xml file="136000000-136100000"> <Id>136000001</Id> <Name>God Deckor</Name> <Email>[email protected]</Email> If I try simple xml load is not working as the document doesn't seem to be valid xml. I can use regex to extract the info with preg_match_all but I feel this is not the right way as the data is already well structured. Any other method ?

  • Reload AJAX data every X minutes/seconds, jQuery

    - by NightMICU
    Hi everyone, I programmed a CMS that has a log of who has recently logged into the system. Presently, this data is fed into a jQuery UI tab via Ajax. I would like to put this information into a sidebar on the main page and load it via AJAX every 30 seconds (or some set period of time). How would I go about doing this? Does the PHP response need to be JSON coded? I am fairly new to AJAX and JSON data. Here is the PHP I am currently using to pull details from the users table- <?php $loginLog = $db->query("SELECT name_f, name_l, DATE_FORMAT(lastLogin, '%a, %b %D, %Y %h:%i %p') AS lastLogin FROM user_control ORDER BY lastLogin ASC LIMIT 10"); while ($recentLogin = $loginLog->fetch()) { echo $recentLogin['name_f'] . " " . $recentLogin['name_l'] . " - " . $recentLogin['lastLogin']; } ?> Thanks!

  • what is a TOPIC in Struts2

    - by nacho4d
    HI, I am learning struts 2 with Tiles 2 and the word "topic" shows up very frequently... What is a topic? for example: The sx:a tag (specifically the ajax a template) and the div tag support an ajax event system, providing the ability to broadcast events to topics. You can specify the topics to listen to using a comma separated list in the listenTopics attribute. What this means is that when a topic is published, usually through the ajax a template, the URL specified in the href attribute will be re-requested. Placeholder... Refresh

  • How can I update only certain fields in a Django model form?

    - by J. Frankenstein
    I have a model form that I use to update a model. class Turtle(models.Model): name = models.CharField(max_length=50, blank=False) description = models.TextField(blank=True) class TurtleForm(forms.ModelForm): class Meta: model = Turtle Sometimes I don't need to update the entire model, but only want to update one of the fields. So when I POST the form only has information for the description. When I do that the model never saves because it thinks that the name is being blanked out while my intent is that the name not change and just be used from the model. turtle_form = TurtleForm(request.POST, instance=object) if turtle_form.is_valid(): turtle_form.save() Is there any way to make this happen? Thanks!

  • What are the new features in Java 7

    - by T.K.
    What is the most official Java 7 feature list? I find very little useful information regarding this on the official JDK 7 site. Apart from that I can only find blogs with people summarizing "some" of the new features. However, some of these blog entries are old and some of them claim that these features "may or may not" be included in Java 7. Can anyone provide a list of features that will definitely be included in Java 7? I would also very much like to know the estimated release date. Will it be backwards compatible with my existing Java EE 6 stuff. That is, will I be able to switch seamlessly using EJBs, JPA2, Glassfish 3 and so on. The feature I am mostly interested in is Closures, so I'll happily switch to Java 7 as soon as a stable release comes out. Thanks!

  • External USB devices to Android phones?

    - by Doughy
    I would like to use Android phones as a way to do some processing and visualization of a sensor that would be attached to the USB port on the phone. The sensor would plug into the micro/mini USB, and then I would need to read the incoming data from the USB serial port. Is this possible? I have heard of people using Android to steer robots and other applications, but I have never seen Android being used as a host for a USB sensor. I can't seem to find any official documentation on the subject either, but it seems like it would be a very useful tool. Any thoughts, links, or information on this matter? Thanks.

    - by lucavb
    i need to port a VS2005 Project (.NET2) to a VS2008 (.NET3.5) (or to VS2010 .NET4 not yet defined). The project is composed by: resources and configuration files (VS project files, like: .settings .vbproj .myapp .config .xconfig .Designer.vb); a lot of VB codes; xsc, xsd, xss and xsx files; a lot of Crystal reports for VS2005; graphical resources. The application take data in order to generate reports from more DB SQL Server 2005 istances. What is the best way to approach to a migration activity? Is there an internal migration tool? If yes, what's the best practice to use it? Which kind of files will be automatically ported to the new VS version? Thanks in advance for all the provided information

  • Intercommunication between Java Chat Servers

    - by Pravingate
    I have a application in which I am using socket programming , having this(image) scenario. Where number of clients will try to connect Broadcast server. Now here I am managing load through LVS(Load balancer). so as a example shown in image, suppose 200 clients will wish to login for broadcast they will be distributed as 100 users on server 1 and another 100 users on server 2.clients will get connected to servers using TCP connection. Now I am maintaining user information on server side in arraylist which will be stored in heap memory,Now the problem is if client wish to broadcast to all logged in users, but that particular client is logged in server 1. and so client will not be able to broadcast another 100 users from server 2. Because both ther servers are unaware about each others state. please suggest to solve this scenario by whatever means you want.

  • How do check if PDO object is connected properly inside a different class?

    - by tgun926
    I want to fetch some information from my mysql database in a class, so I'm passing in the PDO object into a __construct function, and working from there. However, what's an elegant way of checking to see if the PDO object was correctly created, and that the connection is open when the Table class is instantiated? class Table{ public function __construct(PDO $db, $week){ try{ $query = $db -> query ("SELECT * FROM `table1` where `day` = 'monday'"); } catch(PDOExeption $e){ echo 'error: '. $e->getMessage(); //die(); } } } I don't think this code does what I want.

  • ASP.NET - remote screenshot

    - by ufoq
    Hi All, I made a very very simple small app to take screenshot of the desktop and send to network share. About 10 PC's would have this app installed. My idea is, that there will be one dashboard in ASP.NET, which simply shows those screenshots on the webpage. So far, easy stuff. But, because I don't want to clog the network and send the screenshot every 1 minute, I would like to launch the .exe on the remote PC's by demand of ASP.NET user. Unfortunately I haven't found any information (and I'm a complete ASP.NET n00b), how to launch remote executable IN the context of the remote PC (so I won't see screenshots of ASP server :) ) If there is no such possibility, please advise about other way to solve this.

  • Good resources for versioning...

    - by stephmoreland
    I have a number of Windows servers at work that are used for staging web sites for clients while they are being created. I wanted to start using versioning on them so that when we work with outside vendors on a project, if/when they overwrite my work, I'd like to be able to go back and get the version before. My question is that I think I'm not looking for the correct terms in searching for information, but what kind of resources are there to learn how to install the software for versioning or a site to help me get started. Any and all suggestions would be appreciated. Steph

  • Cakephp: Designpattern for creation of models in hasMany relationship

    - by Chris
    I have two Models: Car and Passenger. Car hasMany Passenger Passenger belongsTo Car I managed to create add functionailty for each model and managed to resolve the hasMany relationship between them. Now I'm trying to create a addCar function and view that allows the user to create a new car and automatically generate Passengers. I thought of something like this The view asks the user enter the car information The view has some field that allows to temporarly add new passengers and remove remove them When the user saves the new car, the entities for the passengers are created, the entity for the car is created and the passengers are linked to the car. If the user decides to cacnel everything, the DB remains unchanged. Now my question is: What is the best way to do this? Is there a pattern / tutorial to follow for such a entity and associated subentity creation? To clarify: The passengers associated with each car do not exist prior to the existence of the car.

  • How to Get the Method/Function Call Trace for a Specific Run?

    - by JackWM
    Given a Java or JavaScript program, after its execution, print out a sequence of calls. The calls are in invocation order. E.g. main() { A(); } A() { B(); C(); } Then the call trace should be: main -> A() -> B() -> C() Is there any tool that can profile and output this kind of information? It seems this is common a need for debugging or performance tuning. I noticed that some profilers can do this, but I prefer a simpler/easy-to-use one. Thanks!
