  • Why does Color.IsNamedColor not work when I create a color using Color.FromArgb()?

    - by Jon B
    In my app I allow the user to build a color, and then show him the name or value of the color later on. If the user picks red (full red, not red-ish), I want to show him "red". If he picks some strange color, then the hex value would be just fine. Here's sample code that demonstrates the problem: static string GetName(int r, int g, int b) { Color c = Color.FromArgb(r, g, b); // Note that specifying a = 255 doesn't make a difference if (c.IsNamedColor) { return c.Name; } else { // return hex value } } Even with very obvious colors like red IsNamedColor never returns true. Looking at the ARGB values for my color and Color.Red, I see no difference. However, calling Color.Red.GetHashCode() returns a different hash code than Color.FromArgb(255, 0, 0).GetHashCode(). How can I create a color using user specified RGB values and have the Name property come out right?

  • How can I get "Copy to Output Directory" to work with Unit Tests?

    - by spoon16
    When I build a unit test project before the tests are executed the test output is copied to a TestResults folder and then the tests are executed. The issue I'm having is that not all the files in the Debug/bin directory are copied to the TestResults project. How can I get a file that is copied to the Debug/bin directory to also be copied to the TestResults folder? EDIT: Here is a link to a similar question on another site (no answer there though), http://www.eggheadcafe.com/software/aspnet/29316967/files-and-unit-testing-wi.aspx

  • How does multiple implementing multiple COM interfaces work in C++?

    - by Martin
    I am trying to understand this example code regarding Browser Helper Objects. Inside, the author implements a single class which exposes multiple interfaces (IObjectWithSite, IDispatch). His QueryInterface function performs the following: if(riid == IID_IUnknown) *ppv = static_cast<BHO*>(this); else if(riid == IID_IObjectWithSite) *ppv = static_cast<IObjectWithSite*>(this); else if (riid == IID_IDispatch) *ppv = static_cast<IDispatch*>(this); I have learned that from a C perspective, interface pointers are just pointers to VTables. So I take it to mean that C++ is capable of returning the VTable of any implemented interface using static_cast. Does this mean that a class constructed in this way has a bunch of VTables in memory (IObjectWithSite, IDispatch, etc)? What does C++ do with the name collisions on the different interfaces (they each have a QueryInterface, AddRef and Release function), can I implement different methods for each of these?

  • Strange problem with VSS: VSS doesn't work after 5 p.m.

    - by afsharm
    I have a very strange problem with Visual Source Safe. I use VSS as a add-on with VS 2008 in a corporate intranet with 5 other colleagues. My VS stops working after 5 p.m. most of days with complaining can not connect Source Safe. I'm running VS 2008 and VSS 2005 on Vista and no other one in corporate have such a problem. What do you think about its cause? Is there any log for VSS?

  • Rails 3 : Can't get form_for to work as a 'delete' following the RESTful achitecture => always giving a ROUTING ERROR

    - by Alex
    I have a very simple render that goes as follow: <%= form_for(:relationships, :url => relationships_path, :html => {:method => 'delete'}) do |f| %> <div><%= f.hidden_field :user_id_to_unfollow, :value => @user.id %></div> <div class="actions"><%= f.submit "Unfollow" %></div> <% end %> When I submit this form it will always give me a Routing Error No route matches "/relationships" on my page. In my relationships controller, I have created all the propers methods: def create ... end def destroy ... end def update ... end def show ... end And in my routes config I have made sure to allow all routes for the relationships controller resources :relationships But I can't seem to get into the destroy method of the controller :( However if I remove the :html => {:method => 'delete'} method parameter in the form_for then I get to the create method of the controller no pb. I don't get it.... Alex

    I am new to Spring and now a days I hear a lot about Spring Framework. I have two sets of very specific questions: Set No. 1: What are annotations in general ? How does annotations works specifically with Spring framework ? Can annotations be used outside Spring Framework or are they Framework specific ?

  • How do I make my Log::Log4perl logger work?

    - by Geo
    Here's the code I have: use strict; use warnings; use Log::Log4perl qw(:easy); Log::Log4perl->init({ level => $DEBUG }); my $logger = Log::Log4perl->get_logger("my.logger"); my $appender = Log::Log4perl::Appender->new("Log::Log4perl::Appender::File",filename => "my.file"); $appender->layout(Log::Log4perl::Layout::SimpleLayout->new); $logger->add_appender($appender); $logger->info("this is an info"); all I want to do is log a message to a file, and have the level show up. I understood that is what the SimpleLayout is for . I'd like to do this without a configuration file. Running the code above shows the following message: Log::Log4perl configuration looks suspicious: No loggers defined

  • How do file references within a PHP Objects work?

    - by bender
    I'm trying to create an PHP object that can load objects in other files on demand when needed. My problem is that when I reference the files based on file location for the class definition, it can not find the files. So file structure: /Test.php /os/os.php (extends kernel) /os/kernel.php /os/libraries/lib1.php /os/libraries/lib2.php /os/libraries/lib3.php In kernel.php, the libraries are referenced as 'libraries/lib1.php'.

  • Spring 3 MVC - Does Anything Just Work? Very Simple Use Case Not Working

    - by jboyd
    index.jsp ... <h1> ${myobject} </h1> ... HomeController.java @RequestMapping(value = "/index") public ModelAndView indexPath() { System.out.println("going home"); return new ModelAndView("index", "myobject", "isastring"); } Output: going home The <h1> on index doesn't show anything, how is this even possible? I absolutely cannot get my index.jsp to show this bean, I've tried using a usebean, I've tried storing it on the session, and now I'm directly placing it in the model. Nothing works. Spring 3 has been like every other spring release, intensely frustrating.

  • In Winform I need ASP.NET like membership and roles stuff. But Roles doesn't work

    - by user512602
    Hi, following http://www.theproblemsolver.nl/usingthemembershipproviderinwinforms.htm I set up the membership & roles providers in app.config and try use it in code. Authentication works well, bur roles always returns empty roles array for connected user. This part works: If Membership.ValidateUser(userName, password) Then ' Set the current application principal information to a known user Dim identity As GenericIdentity Dim principal As RolePrincipal Dim user As MembershipUser user = Membership.GetUser(userName) identity = New GenericIdentity(user.UserName) principal = New RolePrincipal(identity) Threading.Thread.CurrentPrincipal = principal This one doesn't: If principal.IsInRole("Club") Then LoggedInUserRole = "Club" Return True Exit Function End If No error is thrown though. Similarly, if I try to add a user to a known, existing role, an exception is thrown : If Not Roles.IsUserInRole(userName, "club") Then Roles.AddUserToRole(userName, "club") End If Exception msg is: Cannot find role '' (I mean the role name isn't given back in exception.) Any clue? Please do not tell me to use Windows Client Administration within project services, I need my own SQL DB connection + the client app services is a bloated dfeature, bug prone.

  • How to Work Around Limitations in Generic Type Constraints in C#?

    - by Jose
    Okay I'm looking for some input, I'm pretty sure this is not currently supported in .NET 3.5 but here goes. I want to require a generic type passed into my class to have a constructor like this: new(IDictionary<string,object>) so the class would look like this public MyClass<T> where T : new(IDictionary<string,object>) { T CreateObject(IDictionary<string,object> values) { return new T(values); } } But the compiler doesn't support this, it doesn't really know what I'm asking. Some of you might ask, why do you want to do this? Well I'm working on a pet project of an ORM so I get values from the DB and then create the object and load the values. I thought it would be cleaner to allow the object just create itself with the values I give it. As far as I can tell I have two options: 1) Use reflection(which I'm trying to avoid) to grab the PropertyInfo[] array and then use that to load the values. 2) require T to support an interface like so: public interface ILoadValues { void LoadValues(IDictionary values); } and then do this public MyClass<T> where T:new(),ILoadValues { T CreateObject(IDictionary<string,object> values) { T obj = new T(); obj.LoadValues(values); return obj; } } The problem I have with the interface I guess is philosophical, I don't really want to expose a public method for people to load the values. Using the constructor the idea was that if I had an object like this namespace DataSource.Data { public class User { protected internal User(IDictionary<string,object> values) { //Initialize } } } As long as the MyClass<T> was in the same assembly the constructor would be available. I personally think that the Type constraint in my opinion should ask (Do I have access to this constructor? I do, great!) Anyways any input is welcome.

  • Why won't my AJAX controls work? (and ajax for .net 4 not working?)

    - by Nicklamort
    I'm totally new to ajax. I'm using VS2005. I just downloaded .NET framework 4 and so then I downloaded ajaxcontroltoolkit.binary.net4 via [http://ajaxcontroltoolkit.codeplex.com/releases/view/43475] (as opposed to ajaxcontroltoolkit.binary.net35 for .NET 3.5), but when I try to load the ajaxcontroltoolkit.dll into my toolbox (as said in the tutorials), I get the following error msg: "'C:......\ajaxcontroltoolkit.dll' is not a microsoft .NET module." First question: Why is this happening? So I tried downloading the "Recommended" ajaxcontroltoolkit.binary.net35, and it accepted the .dll file and loaded all my controls. So, I started a new website and tried to check out a combobox, and it displays, but IE is giving the follow error msg: 'Sys.Extended.UI.PositioningMode.BottomLeft' is null or not an object.' 2nd question: Why is this happening?

  • How can i iterate through QListWidget items and work with each item?

    - by Hossein
    In CSharp its as simple as writting : listBox1.Items.Add("Hello"); listBox1.Items.Add("There"); foreach (string item in listBox1.Items ) { MessageBox.Show(item.ToString()); } and i can easily add different objects to a list box and then retrieve them using foreach. I tried the same approach in Qt 4.8.2 but it seems they are different.though they look very similar at first.I found that Qt supports foreach so i went on and tried something like : foreach(QListWidgetItem& item,ui->listWidget->items()) { item.setTextColor(QColor::blue()); } which failed clearly.It says the items() needs a parameter which confuses me.I am trying to iterate through the ListBox itself, so what does this mean? I tried passing the ListBox object as the parameter itself this again failed too: foreach(QListWidgetItem& item,ui->listWidget->items(ui->listWidget)) { item.setTextColor(QColor::blue()); } So here are my questions: How can I iterate through a QListWidget items in Qt? Can i store objects as items in QListWidgets like C#? How can i convert an object in QListWidgets to string(C#s ToString counter part in Qt) ? (suppose i want to use a QMessagBox instead of that setTextColor and want to print out all string items in the QlistWidget.)

  • Ruby: how does constant-lookup work in instance_eval/class_eval?

    - by Alan O'Donnell
    I'm working my way through Pickaxe 1.9, and I'm a bit confused by constant-lookup in instance/class_eval blocks. I'm using 1.9.2. It seems that Ruby handles constant-lookup in *_eval blocks the same way it does method-lookup: look for a definition in receiver.singleton_class (plus mixins); then in receiver.singleton_class.superclass (plus mixins); then continue up the eigenchain until you get to #<Class:BasicObject>; whose superclass is Class; and then up the rest of the ancestor chain (including Object, which stores all the constants you define at the top-level), checking for mixins along the way Is this correct? The Pickaxe discussion is a bit terse. Some examples: class Foo CONST = 'Foo::CONST' class << self CONST = 'EigenFoo::CONST' end end Foo.instance_eval { CONST } # => 'EigenFoo::CONST' Foo.class_eval { CONST } # => 'EigenFoo::CONST', not 'Foo::CONST'! Foo.new.instance_eval { CONST } # => 'Foo::CONST' In the class_eval example, Foo-the-class isn't a stop along Foo-the-object's ancestor chain! And an example with mixins: module M CONST = "M::CONST" end module N CONST = "N::CONST" end class A include M extend N end A.instance_eval { CONST } # => "N::CONST", because N is mixed into A's eigenclass A.class_eval { CONST } # => "N::CONST", ditto A.new.instance_eval { CONST } # => "M::CONST", because A.new.class, A, mixes in M

  • Why does this attempt at preloading images with jQuery not work?

    - by Eric
    Current I have this code: var imgCount = 36; var container = $('#3D-spin'); var loaded = 0; function onLoad() { alert(loaded); loaded++; if(loaded >= imgCount) { alert('yay'); } } for(var i = imgCount-1; i >= 0; i--) { container.prepend( $('<img>') .one('load', onLoad) .attr('alt', 'View from '+(i*360/imgCount)+'\u00B0') .attr('src', '/images/3d-spin/robot ('+i+').jpg') ); } However, it's behaving VERY strangely. Normally, I get no alert boxes. However, if I open developer tools, and pause script execution, I get a single alert that says 0. There's nothign like a good old heisenbug! A live example can be found here. The script itself is called style.js, and it is clear that images have loaded. Am I doing something stupidly, or is jQuery playing up?
