  • Highlight certain choices in a combo box

    - by calico-cat
    I've got a dropdown box with some items in it that are more popular than others, and I'd like those to have a different background colour (say, Color.AliceBlue) when the combobox is expanded. I see BackColor but is there a way to apply background colour to just a single item?

  • Grammar/own-written parser?

    - by wvd
    Hello all, I'm doing some small projects which involve having different syntaxis for something, however sometimes these syntaxis are so easy that using a parser generator might be overkill. Now, when should I use a own-made parser, and when should I use a parser generator? Thanks, William van Doorn

    - by metal-gear-solid
    Is it good to add line-height in body{line-height:1.5} or it would be better if i add separately for tag by tag like p{ line height:1em} etc. Edit: body {line-height:in em} create problem with if we put image with float inside Edit: 24 April 2010: If i have to add different line heights to elements like p { 1.4} h1 {1.6} h2 { 1.2} ul li { 1.1} then shouldn't i use line height in body { 1.4} if body { 1.4} and h1 {1.6} then what would be line height for h1?

  • Ruby 1.9 and Rackspace's email api (SOAP)

    - by kjs3
    Is anyone out there working with SOAP on Ruby 1.9? Rackspace has email addresses for $2/month and an api to programmatically create/destroy accounts which looks like the best I've found. Fusemail has $2 addresses too but you need a minimum of 80 to get access to the api. So, I either need to find a solution to working with Rackspace or a different email host.

  • Does EGit mandate installing JGit?

    - by Souper
    After using Git from the command line for a while, I am ready for the convenience a GUI plugin (for Eclipse) can offer. However, I prefer a Git plugin similar to to MS Visual Studio's Git Source Control Provider which is only a wrapper around the already installed msysgit. I really don't want two different Git implementations accessing the same repository. EGit sounds perfect - if it can use the already installed msysgit in my PC. But can it?

The internet is a big place, so with a few suggestions some of us may find a new favorite app.

  • Design Pattern for "Context Sensitive" Right Click Menu

    - by MadSeb
    Hi, What is a design pattern I can use for generating "context-sensitive" right click menus ? I have in mind a "Windows Explorer"-like application where a user can right click on a folder and get a list of menu items but right click on a drive and get a totally different list. What design pattern should I use ? Would the factory design pattern be appropiate for handling such a menu ? Regards, Seb

  • which of these modes : cbc,cfb,ctr,ecb,ncfb,nofb,ofb,stream are secure and which are absolute no-no

    - by user393087
    By security I mean that encoded string is indistinguishable from random noise and is different on every encryption of the same text so it is impossible to make a guess on encryption algorithm used or do any dictionary attack on the encoded text. Second: output string length does not correspond to the input string length in easy way, so it is not possible of make guessing on that account. Third: it is possible to verify that the provided password is incorrect so the decoding function could return false instead of supposedly decoded random string.

  • Is application is runned under IIS or VS web-server

    - by zerkms
    How to determine whether asp.net (mvc2) application is running under IIS (7) or VS internal web-server? Clarification why I need this: I'm composing different dependency graph for IoC-container (ninject) that depends on the workaround (develop - when local VS, and production - when IIS) Or may be another great solution so I can simply differ 3 workarounds: local (VS), test server (IIS) or production server (IIS). How in this case to differ the server? By PC name?

  • What's the BPF for HTTP?

    - by Gtker
    The definition can be seen here. The candidate answer may be tcp and dst port 80,but can tcp and dst port 80 guarantee it's HTTP traffic and includes all HTTP traffic? It seems not,because some site can be visited by specifying a different port other than 80 this way: http://domain.name:8080 So my question is: what's the exact BPF for HTTP?

  • Problem with user login validation by authlogic

    - by Andrei
    Hi, I want to use email for signing in, and to allow users to have similar names. One way to do this is to rename login/username field to something different. However, I want to do it just by setting up authlogic. I tried the following acts_as_authentic do |c| c.login_field :email c.validate_login_field false c.validate_email_field true end but it still complains that the login already exists. What must be done to avoid username validation without renaming the field?

  • Multiple layouts in rails [Newbie Q]

    - by BriteLite
    Hi. As a newb, I decided to build a "home inventory" application. I am now stuck on how to programmatically select a layout based on what type of item it is when viewing it in a browser. According to my planning, so far I should have created a few models to represent types of items I can find in my home: Furniture, Electronics and Books. class Book < ActiveRecord::Base end class Furniture < ActiveRecord::Base end class Electronic < ActiveRecord::Base end Now the Books model has things like isbn, pages, address, and category. Furniture model has things like color, price, address, and category. Electronics has things like name, voltage, address, and category. Here is where I got confused. I know the property address is going to be the same for all of them. I also know that, I will need to create multiple "layouts" for 3 different types of items to show the different properties of said items with appropriate graphics and stylesheets. But how will I go about deciding which category the item is so I can determine which layout to render. According to me, this is how I will do it: class DisplayController < ApplicationController def display @item = Params[:item] if @item.category = "electronics" render :layout => 'electronics' end end In my routes.rb map.display ':item', :controller => 'display', :action => 'display' I only seem to have one concern with this, I probably will add a lot of categories later on and think there should be a more DRY-esque way of dealing, rather than hardcoding them. I understand that I need to add into my layout html tags to display relevant information for that particular category. ----Questions---- Is this the right way to approach this type of problem. Will this approach be compatible when I decide to add a gem like *thinking_sphinx* to run search. What issues do you see with my approach and how can I make it better. I was reading something about "Polymorphic Assoc", does that apply in this case, since category exist for all items? Also, I was trying to get a routes to render a URL like "http://localhost/living-room-tv"

  • Get more than 7 dimensions in google analytics

    - by Paritosh Singh
    I am fetching my data from google analytics core api. I came to know that we can fetch only 7 dimensions using api, But here I need to fetch more than 7 dimensions with correct metrics. Is there anyway (other than using paid google analytics) to fetch more than 7 dmensions with correct metrics from google analytics. If not, then is there any mathematical formula through which we can find intersection of dimensions fetched using 2 different dimensions having one dimension in common. Thanks
