partial

问题 I need to count the number of classes in correct C# source file. I wrote the following grammar: grammar CSharpClassGrammar; options { language=CSharp2; } @parser::namespace { CSharpClassGrammar.Generated } @lexer::namespace { CSharpClassGrammar.Generated } @header { using System; using System.Collections.Generic; } @members { private List<string> _classCollector = new List<string>(); public List<string> ClassCollector { get { return _classCollector; } } } /*-----------------------------------

问题 I've seen a couple questions on this but haven't been able to solve it... I'm trying to pass a parameter while rendering a partial (similar to domainname.com/memory_books/new?fbookupload=yes) Right now, I use this line: <%= render :partial => '/memory_books/new', :fbookupload => "yes" %> and in the partial, I have tried to get the content of fbookupload by using: <%= fbookupload %> which gives an "undefined local variable" error and <%= params.inspect %> which does not show fbookupload as a

问题 We're using a FileStreamResult to provide video data to a Silverlight MediaElement based video player: public ActionResult Preview(Guid id) { return new FileStreamResult( Services.AssetStore.GetStream(id, ContentType.Preview), "application/octet-stream"); } Unfortunately, the Silverlight video player downloads the entire video file before it starts playing. This behavior is expected as our Preview Action does not support downloading partial content. (side note: if the file is hosted in an IIS

问题 I'd like to know how to find a variable in the base MATLAB Workspace by entering only a part of its name. I have a long list of variables & I don't know the exact variable name. Is there a function that compares/matches character order in a list of variable strings? Thanks, 回答1: You can use who to obtain a list of all variable names currently in your workspace. From there, you can use regexpi to do a case insensitive regular expression lookup to find those variables that match your query.

问题 I'm trying to load part of big JPEG file (hundreds of megapixels) with a limited memory footprint. I need only about a 1000 scanlines of 20000. It seems that current implementation of libjpeg (as well as its fork libjpeg-turbo) doesn't provide a way to skip unneeded 19k scanlines without decoding them. Is there a workaround for it without digging into libjpeg internals? 回答1: Partial JPEG decoding was implemented in jpeglib-turbo one year ago. I didn't try it, but I guess it should work. Check

问题 I use Jvectormap into my Rails 3 app. When I click on it, I want to hide the map and visualize a partial with information about the selected country. I handle the map click and I send a GET req to the server. users.js.coffee.erb $ -> $("#world-map").vectorMap onRegionClick: (event, code) -> $('#world-map').hide(1000) $.get('/users/statistics', {code: code}); $('#statistics').show(1000) users_controller.rb def statistics @country = Country.find_by_two_letter_code((params[:code]).downcase)

问题 I followed the Getting Started With Rails tutorial to set up a simple blog with comments. I went to apply it to my own scenario: histories with history items. Everything was more or less fine until I realized that I needed to have the ability to edit these history items (kind of like editing comments). I've got it so there's an "Edit Item" link on the partial that displays the history items. It seems to hit the edit action in the history items controller. But I get a form with blank fields

问题 I would like to ask about a question relating to normalization. I have 2 PKs, VIN and Reg_no. VIN is the Vehicle ID Number and Registration number is the car plate number. I have an attribute called current odometer. Does it have a partial dependency or a full dependency on the 2 PKs? 回答1: I have 2 PKs, VIN and Reg_no. VIN is the Vehicle ID Number and Registration number is the car plate number. You have two candidate keys. VIN is unique; the plate number is also probably unique. (But it

问题 I have the following codes: var filteredRange = rangeVals.filter(function(val){ return val[C2] == "ANTHONY"; }); This code works fine for an exact match. But if I would like to look for any values that ends with Y, this does not return anything: var filteredRange = rangeVals.filter(function(val){ return val[C2] == "*Y"; }); I have tried to us wildcard "%Y" but apparently this is not the correct way either. I have tried to look into this resource of RegExp from MDN but I can't seem to
