resources

问题 I've got three (relevant) models, specified like this: class User < ActiveRecord::Base has_many :posts has_many :comments has_many :comments_received, :through => :posts, :source => :comments end class Post < ActiveRecord::Base belongs_to :user has_many :comments end class Comment < ActiveRecord::Base belongs_to :user belongs_to :post end I'd like to be able to reference all the comments_received for a user with a route - let's say it's for batch approval of comments on all posts. (note that

问题 Solved! See below. I have 2 C# applications. Application a is supposed to modify the internal resources of application b. Application b is supposed to do something with its (modified) resources when executed. How can I accomplish that? Here is what I tried: public static void addFileToResources(string dest, string src) { Assembly a_dest = Assembly.LoadFile(dest); using (Stream s_dest = a_dest.GetManifestResourceStream("Elevator.Properties.Resources.resources")) { using (ResourceWriter rw =

问题 I have to read a file containing a list of strings. I'm trying to follow the advice in this post. Both solutions require using FileUtils.readLines , but use a String , not a File as the parameter. Set<String> lines = new HashSet<String>(FileUtils.readLines("foo.txt")); I need a File . This post would be my question, except the OP was dissuaded from using files entirely. I need a file if I want to use the Apache method, which is the my preferred solution to my initial problem. My file is small

问题 I know we can do something like this: Class.class.getResourceAsStream("/com/youcompany/yourapp/module/someresource.conf") to read the files that are packaged within our jar file. I have googled it a lot and I am surely not using the proper terms; what I want to do is to list the available resources, something like this: Class.class.listResources("/com/yourcompany/yourapp") That should return a list of resources that are inside the package com.yourcompany.yourapp.* Is that possible? Any ideas

问题 The assembly qualified string used as a parameter below for a Uri works in XAML, but gives me the error shown when used in code. I tried every kind of UriKind with the same result. How can I fix this? [Test] public void LargeImageSource_IsKnown() { var uri = new Uri( "pack://application:,,,/" + "MyAssembly.Core.Presentation.Wpf;component/" + "Images/Delete.png", UriKind.RelativeOrAbsolute); Assert.That( _pickerActivityCollectionVm.DeleteActivityCommand.LargeImageSource, Is.EqualTo(uri)); }

问题 I'm looking for a way to essentially give an item in a ResourceDictionary multiple keys. Is there a way to do this? <DataTemplate x:Key="myTemplate" ... /> <AliasedResource x:Key="myTemplateViaAlias" Target="myTemplate" OR_Target={StaticResource myTemplate} /> When I call TryFindResource("myTemplateViaAlias") I want to get myTemplate out. I suppose I could create an AliasedResource class myself and dereference it in code when I get it out of the dictionary, but I'd rather not do that if there

问题 I would like to get a byte array from an jpeg image located in my res/drawable file ? Does anyone know how to do that please ? 回答1: Get a bitmap decodeResource(android.content.res.Resources, int) Then either compress it to ByteArrayOutputStream() or copyPixelsToBuffer and get your array from the buffer. http://developer.android.com/reference/android/graphics/Bitmap.html 回答2: Drawable drawable; Bitmap bitmap = ((BitmapDrawable) drawable).getBitmap(); ByteArrayOutputStream stream = new

问题 In my project I have a DLL for some WPF/XAML controls that need to play some audio files. Now, with SoundPlayer I can make these audio files "Embedded Resources" of the DLL (that also contains the WPF controls). However, SoundPlayer has some severe limitation so I switched to MediaPlayer. Unfortunately, the MediaPlayer help page states that MediaPlayer can't work with resources. (I tried using Pack URIs anyway but this didn't work - at least none of the combinations I've tried.) So, for now,
