  • Undetermined type conversion in VB.NET 2008

    - by user337501
    I figured this would be a quick google, but extensive searching hasnt yielded any results. Everything about type conversion seems to dance around this concept. I want to get the type of variable "a", and make a new variable named "b" of that type. Otherwise I could have "a" as a type already declared and "b" simply as an Object, then try to cast "b" to the type of "a". Dim a As Integer Dim b As Whatever a Is OR TryCast(b, Whatever a Is) I would also like to make the conversion using a variable representation of the type, but cant find info on how to do that either. Sorta like: Dim a As Integer Dim b As Object Dim t As Type t = a.GetType() TryCast(b, t) Realizing I'm completely misusing TryCast here, I'm mostly trying to get my goal across. I figured it would be an easy quick thing to do but I cant really find any specific info on it. Any ideas?

  • Rails 3 routing - what's best practice?

    - by Mattias
    Hi guys, I'm trying out Rails, and I've stumbled across an issue with my routing. I have a controller named "Account" (singular), which should handle various settings for the currently logged in user. class AccountController < ApplicationController def index end def settings end def email_settings end end How would I set-up the routes for this in a proper manner? At the moment I have: match 'account(/:action)', :to => 'account', :as => 'account' This however does not automagically produce methods like account_settings_path but only account_path Is there any better practice of doing this? Remember the Account controller doesn't represent a controller for an ActiveModel. If this is in fact the best practice, how would I generate links in my views for the actions? url_to :controller => :account, :action => :email_settings ? Thanks!

  • JSF Open new window and display bean data

    - by JSFPRINTER
    I am running JSF 2.0 and the latest version of Primefaces 2.2RC1 I believe. I am trying to create a printer friendly window. When the user clicks on a p:commandLink I want a new window to open and display a xhtml file I have named printView.xhtml. Now I can get the window working fine using JavaScript window.open but when I open the new window it will not render any values it just displays everything as #{myBean.value}. Does anyone know how to properly open a window and extend the current scope of the application into that window so I can call all of my managed beans properly and display the values etc. etc.

  • Need help from CSS purist!

    - by Darcy
    I'm beginning to use CSS more and more but I'm not sure if I'm using it as intended in all cases. I have classes named things like 'box' that will wrap the content inside it with a border, which seems like good CSS to me. On the other hand I have classes like 'margin-right-5' and 'float-left' that sets the css to margin-right: 5px and float:left respectively. I'm wondering if this is good practice. Then in my markup I'd do something like: <div class="box float-left margin-right-5"> <!-- CONTENT HERE --> </div> Sometimes I may want to float right or not have a margin at all and still use the 'box' class, so I use several classes in order to make the css more flexible. Am I destroying the principles of CSS?

  • How do I correctly use two Not Exists statements in a where clause using Access SQL VBA?

    - by Bryan
    I have 3 Tables: NotHeard,analyzed,analyzed2. In each of these tables I have two columns named UnitID and Address. What I'm trying to do right now is to select all of the records for the columns UnitID and Address from NotHeard that don't appear in either analyzed or analyzed2. The SQL statement I created was as follows: SELECT UnitID, Address INTO [NotHeardByEither] FROM [NotHeard] Where NOT EXISTS( Select analyzed.UnitID FROM analyzed WHERE [NotHeard].UnitID = analyzed.UnitID) or NOT EXISTS( Select analyzed2.UnitID FROM analyzed2 WHERE [NotHeard].UnitID = analyzed2.UnitID) Group BY UnitID, Address I thought this would work since I've used the single NOT EXISTS subquery line and it has worked just fine for me in the past. The above query however returns the same data that is in the NotHeard table whereas if I take out the or NOT EXISTS part it works correctly. Any ideas as to what I'm doing wrong or how to do what I'm wanting to do?

  • What are the steps for making domain-neutral assemblies?

    - by Mystagogue
    ...and can those steps also be applied to a 3rd party assembly (that might already be strong-named)? The context for my question should not be important, but I'll share anyway: I'm thinking of making a logger (or log-wrapper) that always knows what "log source" to target, regardless of whether the assemblies using it are in one appdomain, or spread across several appdomains. I think one way to achieve that, is to have a domain-neutral assembly with a static "LogSource" property. If that static property is set in a domain-neutral assembly, I think all appdomains will see it.

  • Entity Framework 4.1 (Code First) audit column

    - by Ken Pespisa
    I'm using Entity Framework 4.1 with a Code-First approach on an ASP.NET MVC site Say I have an entity named Profile that keeps track of a user's favorite book, and I want to track when the user updates their favorite book. UPDATED: Using the class below as an example, I want to set the FavoriteBookLastUpdated property to the current date whenever the value of the FavoriteBook property changes. public class Profile { public int Id { get; set; } public string Name { get; set; } public string FavoriteBook { get; set; } public DateTime? FavoriteBookLastUpdated { get; set; } } Right now I just update that field, if appropriate, in the controller's Edit action before calling the DBContext's SaveChanges() method. Is there a way I can put that logic in my model somehow? I'd prefer not to use triggers on the database side.

  • Error using MVCContrib TestHelper

    - by Brian McCord
    While trying to implement the second answer to a previous question, I am receiving an error. I have implemented the methods just as the post shows, and the first three work properly. The fourth one (HomeController_Delete_Action_Handler_Should_Redirect_If_Model_Successfully_Delete) gives this error: Could not find a parameter named 'controller' in the result's Values collection. If I change the code to: actual .AssertActionRedirect() .ToAction("Index"); it works properly, but I don't like the "magic string" in there and prefer to use the lambda method that the other poster used. My controller method looks like this: [HttpPost] public ActionResult Delete(State model) { try { if( model == null ) { return View( model ); } _stateService.Delete( model ); return RedirectToAction("Index"); } catch { return View( model ); } } What am I doing wrong?

  • How do I get PyLint to find namespace packages?

    - by tjd.rodgers
    I have a virtualenv where I've installed two packages, both using the company.project_name namespace. So the first package is importable from company.project_name.one and the second from company.project_name.two. The challenge is that I can't seem to be able to run PyLint on either one of them. If I issue: $ pylint company.project_name.one I get: ************* Module company.project_name.one F: 1, 0: No module named project_name.one(fatal) I suspect that I'm probably doing something wrong. Is there a proper way to do this? Edit: I should have made it clear that company.project_name and company are namespace packages and not regular packages.

  • How to add/register helpers with Zend Framework

  • Controller with same name as an area - Asp.Net MVC4

    - by Trober
    I have a Contacts controller in the main/top area, and I have an area named "Contacts". I get POST 404s to the Contacts controller if I register my areas before I register my top-level routes: protected void Application_Start() { AreaRegistration.RegisterAllAreas(); ModelBinders.Binders.DefaultBinder = new NullStringBinder(); RouteConfig.RegisterRoutes(RouteTable.Routes); } And, if I register my areas after my routes, my 404s to the Contacts controller goes away, but my routes to the Contacts area are now 404s. ...lots of duplicate controller name questions logged, but I haven't found a specific scenario where the area is the same name as the controller. ...probably an easy fix. Would appreciate help. :-D

  • Array::include? on ActiveRecord collection not calling op== ?

    - by tribalvibes
    Given a collection of named Foos from ActiveRecord, why does Array.include? not seem to call Foo.== but yet index does? class Foo < ActiveRecord::Base def ==(s) self.name == s end end class Bar < ActiveRecord::Base has_many :foos end bar.foos << Foo.new( :name = 'hmm' ) bar.foos.all.include?('hmm') # does select all from db every time = true bar.foos.include?('hmm') # does not go to db, but does not find the Foo! = false bar.foos.index('hmm') # does not go to db, but does find the Foo[0] ! = 0 bar.foos.index('eh') # no such object = nil I understand shallow about the proxies, but (without a detour into the AR source) why is index seemingly behaving correctly but include? is not !? Is this a bug in the proxy behavior, and/or is this behavior documented somewhere ? Thanks.

  • Best Ruby ORM for Wrapping around Legacy SQL Server Database?

    - by Technocrat
    Hi. I found this answer and it sounds like almost exactly what I'm doing. I have heard mixed answers about whether or not datamapper can support SQL Server through dataobjects. Basically, we have an app that uses a consistently structured database, consistently named tables, etc in SQL Server. We're making all kinds of tools and stuff that have to interact with it, some of them remotely and so I decided that we need to create some common, simple access point to do read/write operations on the SQL Server app since it's API is all C# and other things I despise. Now my question is if anyone has any examples or projects they know of where a ruby ORM can essentially create models for another application's legacy database by defining the conventions of each model's pkeys, fkeys, table names, etc. Sequel is the only ORM I've used with SQL Server but never to do anything quite like this. Any suggestions?

  • How to name variables wich 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 captialized 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

  • RIA Services - Two entity models share an entity name

    - by Alex
    I have two entity models hooked up to two different databases. However, the two databases both have a table named 'brand', for example. As such, there is a naming conflict in my models. Now, I've been able to add a namespace to each model, via Custom Tool Namespace in the model's properties, but the generated code in my Silverlight project will try to use both namespaces, and come up with this, Imports MyProject.ModelA Imports MyProject.ModelB Public ReadOnly Property brands() As EntitySet(Of brand) Get Return MyBase.EntityContainer.GetEntitySet(Of brand) End Get End Property giving me this exception: 'Error 1 'brand' is ambiguous, imported from the namespaces or types 'MyProject.ModelA,MyProject.ModelB'. Has anyone had experience with naming conflicts like this using RIA services? How did you solve it?
