  • Method For Making Methods: Easy Ruby Metaprogramming

    - by yar
    I have a bunch of methods like this in view helper def background "#e9eaec" end def footer_link_color "#836448" end I'd like these methods exposed to the view, but I'd prefer the helper to be a bit more concise. What's the best way to turn a hash, say, into methods (or something else)?

  • Import CSV to class structure as the user defines

    - by Assimilater
    I have a contact manager program and I would like to offer the feature to import csv files. The problem is that different data sources order the fields in different ways. I thought of programming an interface for the user to tell it the field order and how to handle exceptions. Here is an example line in one of many possible field orders: "ID#","Name","Rank","Address1","Address2","City","State","Country","Zip","Phone#","Email","Join Date","Sponsor ID","Sponsor Name" "Z1234","Call, Anson","STU","1234 E. 6578 S.","","Somecity","TX","United States","012345","000-000-0000","[email protected]","5/24/2010","z12343","Quantum Independence" Notice that in one data field "Name" there is a comma to separate last name and first name and in another there is not. My plan is to have a line for each field (ie ID, Name, City etc.) and a statement "import to" and list box with options like: Don't Import, BusinessJoin Date, First Name, Zip and the program recognizes those as properties of an object... I'd also like the user to be able to record preset field orders so they can re-use them for csv files from the same download source. Then I also need it to check if a record all ready exists (is there a record for Anson Call all ready?) and allow the user to tell it what to do if there is a record (ie mailing address may have changes, so if that field is filled overwrite it, or this mailing address is invalid, leave the current data untouched for this person, overwrite the rest). While I'm capable of coding this...i'm not very excited about it and I'm wondering if there's a tool or set of tools out there to all ready perform most of this functionality... I hope this makes sense...

  • Using WPF class in a web application, problem with hosting permission

    - by tanathos
    I'm developing a DLL that uses WPF classes to make image manipulation. It works fine in my local environment, but when I try to use it in an hosted web site I retrieve this error: Request for the permission of type 'System.Security.Permissions.MediaPermission, WindowsBase, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' failed. exactly when I try to call the EndInit() of a BitmapImage object: BitmapImage originalImage = new BitmapImage(); originalImage.BeginInit(); originalImage.CacheOption = BitmapCacheOption.OnLoad; originalImage.UriSource = new Uri(physical_imagepath); originalImage.EndInit(); Any suggestion?

  • Casting between value types on a class using generics

    - by marcelomeikaru
    In this section of a function (.NET 2.0): public void AttachInput(T input, int inIndex) where T : struct { if (input is int) { Inputs.Add(inIndex, (int)input); InputCount++; IsResolved = false; } } The compiler shows the error "Cannot convert type 'T' to 'int'. So, I used Convert.ToInt32() which worked - but does it box input to an object? Is there a better solution? Thanks

  • Getting all types from an assembly derived from a base class

    - by CaptnCraig
    I am trying to examine the contents of an assembly and find all classes in it that are directly or indirectly derived from Windows.Forms.UserControl. I am doing this: Assembly dll = Assembly.LoadFrom(filename); var types = dll.GetTypes().Where(x => x.BaseType == typeof(UserControl)); But it is giving an empty list because none of the classes directly extend UserControl. I don't know enough about reflection to do it quickly, and I'd rather not write a recursive function if I don't have to.

  • Using Session State in Public Class in ASP.NET?

    - by davemackey
    I'm trying to move some reusable portions of code into a class. This is working okay except when I attempt to use Session within this class. I get an error: "Cannot refer to an instance member of a class from within a shared method or shared member initializer without an explicit instance of the class." My code looks something like this: Public Class webHousing Inherits System.Web.UI.Page Public Sub GetUserInfo() Dim x as String x = 10 Session("x")= x End Sub End Class I've simplified this code significantly - but the basic problem is present - trying to set a session value from within a class. I found the following MSDN article1 but don't believe Public/Shared can be used on Session?

  • Linq To Xml problems using XElement's method Elements(XName)

    - by Dorian McHensie
    Hello everyone. I have a problem using Linq To Xml. A simple code. I have this XML: <?xml version="1.0" encoding="utf-8" ?> <data xmlns="http://www.xxx.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.xxx.com/directory file.xsd"> <contact> <name>aaa</name> <email>[email protected]</email> <birthdate>2002-09-22</birthdate> <telephone>000:000000</telephone> <description>Description for this contact</description> </contact> <contact> <name>sss</name> <email>[email protected]</email> <birthdate>2002-09-22</birthdate> <telephone>000:000000</telephone> <description>Description for this contact</description> </contact> <contact> <name>bbb</name> <email>[email protected]</email> <birthdate>2002-09-22</birthdate> <telephone>000:000000</telephone> <description>Description for this contact</description> </contact> <contact> <name>ccc</name> <email>[email protected]</email> <birthdate>2002-09-22</birthdate> <telephone>000:000000</telephone> <description>Description for this contact</description> </contact> I want to get every contact mapping it on an object Contact. To do this I use this fragment of code: XDocument XDoc = XDocument.Load(System.Web.HttpRuntime.AppDomainAppPath + this.filesource); XElement XRoot = XDoc.Root; //XElement XEl = XElement.Load(this.filesource); var results = from e in XRoot.Elements("contact") select new Contact((string)e.Element("name"), (string)e.Element("email"), "1-1-1", null, null); List<Contact> cntcts = new List<Contact>(); foreach (Contact cntct in results) { cntcts.Add(cntct); } Contact[] c = cntcts.ToArray(); // Encapsulating element Elements<Contact> final = new Elements<Contact>(c); Ok just don't mind that all: focus on this: When I get the root node, it is all right, I get it correctly. When I use the select directive I try to get every node saying: from e in XRoot.Elements("contact") OK here's the problem: if I use: from e in XRoot.Elements() I get all contact nodes, but if I use: from e in XRoot.Elements("contact") I GET NOTHING: Empty SET. OK you tell me: Use the other one: OK I DO SO, let's use: from e in XRoot.Elements(), I get all nodes anyway, THAT's RIGHT BUT HERE COMES THE OTHER PROBLEM: When Saying: select new Contact((string)e.Element("name"), (string)e.Element("email"), "1-1-1", null, null); I Try to access <name>, <email>... I HAVE TO USE .Element("name") AND IT DOES NOT WORK TOO!!!!!!!!WHAT THE HELL IS THIS????????????? IT SEEMS THAT I DOES NOT MATCH THE NAME I PASS But how is it possible. I know that Elements() function takes, overloaded, one argument that is an XName which is mapped onto a string. Please consider that the code I wrote come from an example, It should work. Please somebody help me. THANKS IN ADVANCE

  • C# Windows Service Intermittent Method Call

    - by Goober
    Scenario I have a C# Windows Service that essentially subscribes to some events and if anything is triggered by the events, it carries out a few tasks. The Thing... ....is that these events are monitoring processes, which I need to restart at certain times of the day. Question What's the best way I can go about performing this task at an exact time? Thoughts so far are: 1)To use a timer that checks what time it is every few minutes. 2)Something that isn't a timer and doesn't suck as an implementation. Help greatly appreciated.

  • JRuby-friendly method for parallel-testing Rails app

    - by Toby Hede
    I am looking for a system to parallelise a large suite of tests in a Ruby on Rails app (using rspec, cucumber) that works using JRuby. Cucumber is actually not too bad, but the full rSpec suite currently takes nearly 20 minutes to run. The systems I can find (hydra, parallel-test) look like they use forking, which isn't the ideal solution for the JRuby environment.
