  • Center four columns in CSS

    - by Ernest
    Hi everybody, I'm trying to make four columns that are centered on the frontpage. I would like it to look like this example: http://www.clutterpad.com/ My code looks like this: #bottom-container {width:100%;height:250px;position:relative;} #bottom-mid {background-color:white;} #bottom-left, #bottom-mid, #bottom-right {height:250px;} #bottom-left, #bottom-right {width:50%;float:left;} #bottom-left {background-color:white;position:absolute;top:0px;left:0px;} #bottom-right {background-color:white;position:absolute;top:0px;left:50%;} #bottom-mid {position:relative;margin:0px auto; width:1000px;z-index:2;} #column-container {width:100%; margin:20px auto;} .column {width:200px;float:left;font-size:10pt;font-family:Arial;margin:20px 10px;} But it's not working out. How should I code it to look like the example I mentioned before?

  • Which C++ graphics library should I use?

    - by mspoerr
    Hello, I found the following graphics libraries, but I am not sure which one I should use. Maybe there are some more... Graphviz (http://www.graphviz.org/) Boost Graph Library (http://www.boost.org/doc/libs/1_42_0/libs/graph/doc/index.html) Lemon (http://lemon.cs.elte.hu/trac/lemon) igraph (http://igraph.sourceforge.net/introduction.html) What it should do: draw a undirected network map come as header only or static lib for Windows the output format should be user editable Graphviz is the only one I tried so far, but I found no static lib for it, I failed to build it by my own and the documentation could be better. Therefore I looked around and found these other three libs. I would be glad to get some recommendations which lib to choose. Thanks, /mspoerr

  • How many records can i store in a Sql server table before it's getting ugly?

    - by Michel
    Hi, i've been asked to do some performance tests for a new system. It is only just running with a few client, but as they expect to grow, these are the numbers i work with for my test: 200 clients, 4 years of data, and the data changes per.... 5 minutes. So for every 5 minutes for every client there is 1 record. That means 365*24*12 = 105.000 records per client per year, that means 80 milion records for my test. It has one FK to another table, one PK (uniqueidentifier) and one index on the clientID. Is this something SqlServer laughs about because it isn't scaring him, is this getting too much for one quad core 8 GB machine, is this on the edge, or..... Has anybody had any experience with these kind of numbers?

  • JavaScript "confirm" on SelectedIndexChange of RadioButtonList

    - by Brian David Berman
    I have a RadioButtonList control and I would like to do a Javascript "confirm" when a user tries to change the index. Currently AutoPostBack is set to TRUE. I can, of course, just call __doPostBack from within a javascript function, etc. I tried a few things with jQuery but you have to worry about mousedown vs. click and then there is always the fact that you can click the checkbox label to select it, etc. Anyone have a nice solution for this? To be clear, I am looking for a way to prompt the user with a confirm box prior to their selection being made and triggering a postback.

  • Can someone give me an overview of ASP.net and how it's different from technologies such as php?

    - by DavidR
    I've been doing the html and css for a site, sending it off to a guy to implement in a web server. I get a call from the designer freaking out about the progress, saying the clients aren't happy. He wants me to personally integrate my css with what's on the site. The site is done in ASP.net, time is short, and I'm a little in over my head. I have an understanding of how php works, but have never worked extensively with it. Looking at the stuff on the ftp, I can't even find equivalent of the index.html file (I know that when I go to the site itself, there is nothing after the base url, i.e., www.site.com/ brings me to the homepage.) Can anyone give me a few tips or links as to what I am to do with this, or where to even being navigating this site?

  • How do I detect a change of tab page in TabControl prior to SelectedIndexChanged event?

    - by JYelton
    I currently determine what page of a tabcontrol was clicked on via the SelectedIndexChanged event. I would like to detect before the selected index actually changes, for validation purposes. For example, a user clicks a tab page other than the one they are viewing. A dialog is presented if form data is unsaved and asks if it's ok to proceed. If the user clicks no, I'd like to remain on the current tab. Currently I have to remember the previous tab page and switch back to it after an answer of 'no.' I considered MouseDown (and the assorted calculation logic), but I doubt that's the best way. (This is in .NET C# 3.5)

  • Is it possible to nest folders in the Flash Builder bin-debug

    - by ThunderChunky_SF
    I'm trying to setup my bin-debug folder so that the structure looks like this: bin-debug assets img swf main.swf css style.css js swfobject.js index.html I've tried setting the project's output folder to: bin-debug/assets/swf which does get my main.swf where I want it, but then my other source folders get dumped into that swf folder as well. What I would really like is to tell Flash Builder to put my swf into a nested folder and to be able to specify where my build folders' output goes as well. Is this at all possible without resorting to ANT scripts?

  • How do I do multiple assignment in MATLAB?

    - by Benjamin Oakes
    Here's an example of what I'm looking for: >> foo = [88, 12]; >> [x, y] = foo; I'd expect something like this afterwards: >> x x = 88 >> y y = 12 But instead I get errors like: ??? Too many output arguments. I thought deal() might do it, but it seems to only work on cells. >> [x, y] = deal(foo{:}); ??? Cell contents reference from a non-cell array object. How do I solve my problem? Must I constantly index by 1 and 2 if I want to deal with them separately?

  • Per query relevance elevation for solr?

    - by plusplus
    I want to tune the relevance of solr search results on a per user basis - based on the number of times the user has clicked through a result before. Frequently hit items FOR THAT USER should rise to the top of their search results. Is there a way to provide custom boost/elevation for particular document ids on the query? I'm thinking in the order of ~100s of particular documents to elevate. The elevation should have no effect if the rest of the query doesn't find those documents. Alternatively, if this isn't possible, what is a sane way for setting up an alternative indexing approach that would make this possible? Could I add a field per user in the index to store their scores? I'm thinking in the order of 1000 users. The major drawback of that approach is the number of times a document would need to be reindexed (i.e. each time it was used by the user).

  • Bulk get of child entities on Google app engine?

    - by dfrankow
    On Google App Engine in Python, I have a Visit entity that has a parent of Patient. A Patient may have multiple visits. I need to set the most_recent_visit (and some auxiliary visit data) somewhere for later querying, probably in another child entity that Brett Slatkin might call a "relationship index entity." I wish to do so in a bulk style as follows: 1. get 100 Patient keys 2. get all Visits that have any of the Patients from 1 as an ancestor 3. go through the Visits and get the latest for each Patient Is there any way to perform step 2 in a bulk get? I know there is a way to bulk get entities from a list of keys, and there is a way to match a single entity by its ancestor.

  • ruby on rails adding new route

    - by ohana
    i have an RoR application Log, which similar to the book store app, my logs_controller has all default action: index, show, update, create, delete.. now i need to add new action :toCSV, i defined it in logs_controller, and add new route in the config/routes as: map.resources :logs, :collection = { :toCSV = :get }. from irb, i checked the routes and see the new routes added already: rs = ActionController::Routing::Routes puts rs.routes GET /logs/toCSV(.:format)? {:controller="logs", :action="toCSV"} then ran ‘rake routes’ command in shell, it returned: toCSV_logs GET /logs/toCSV(.:format) {:controller="logs", :action="toCSV"} everything seems working. finally in my views code, i added the following: link_to 'Export to CSV', toCSV_logs_path when access it in the brower 'http://localhost:3000/logs/toCSV', it complained: Couldn't find Log with ID=toCSV i checked in script/server, and saw this one: ActiveRecord::RecordNotFound (Couldn't find Log with ID=toCSV): app/controllers/logs_controller.rb:290:in `show' seems when i click that link, it direct it to the action 'show' instead of 'toCSV', thus it took 'toCSV' as an id...anyone know why would this happen? and to fix it? Thanks...

  • It seems like the safest way to think of an Inner Join is to think of it as a Cross Join and then sa

    - by Jian Lin
    It seems like the safest way to think of an Inner Join is to think of it as a Cross Join and then satisfying some condition(s)? Because the equi-join can be obvious, but the non-equi-join can be a bit confusing. But if we always use the Cross Join, and then filter out the ones satisfying the condition, then we get the resulting table. In other words, we can always analyze it by using the first record on the left table, and then go through every single records on the right, and then repeat that for 2nd record on the left, and for the 3rd, 4th, ... etc. So in our mind, we can analyze it using this way, and it is like O(n^2), although what happens in the DBMS maybe that it is a lot faster (when an index is present). Is there another good way to think of it besides this method?

  • Performance - User defined query / filter to search data

    - by Cagatay Kalan
    What is the best way to design a system where users can create their own criterias to search data ? By "design" i mean, data storage, data access layer and search structure. We will actually refactor an existing application which is written in C# and ASP .NET and we don't want to change the infrastructure. Our main issue is performance and we use MSSQL and DevExpress to build queries. Some queries run in 4-5 minutes and all the columns included in the queries have indexes. When i check queries, i see that DevExpress builds too many "exists" clauses and i'm not happy with that because i have doubts that some of these queries skip some indexes. What may be the alternatives to DevExpress? NHibernate or Entity Framework? Can we build dynamic criteria system and store these to database in both of them ? And also do we need any alternative storage like a lucene index or OLAP database?

  • Why the difference in speed?

    - by AngryHacker
    Consider this code: function Foo(ds as OtherDLL.BaseObj) dim lngRowIndex as long dim lngColIndex as long for lngRowIndex = 1 to ubound(ds.Data, 2) for lngColIndex = 1 to ds.Columns.Count Debug.Print ds.Data(lngRowIndex, lngColIndex) next next end function OK, a little context. Parameter ds is of type OtherDLL.BaseObj which is defined in a referenced ActiveX DLL. ds.Data is a variant 2-dimensional array (one dimension carries the data, the other one carries the column index. ds.Columns is a Collection of columns in 'ds.Data`. Assuming there are at least 400 rows of data and 25 columns, this code takes about 15 seconds to run on my machine. Kind of unbelievable. However if I copy the variant array to a local variable, so: function Foo(ds as OtherDLL.BaseObj) dim lngRowIndex as long dim lngColIndex as long dim v as variant v = ds.Data for lngRowIndex = 1 to ubound(v, 2) for lngColIndex = 1 to ds.Columns.Count Debug.Print v(lngRowIndex, lngColIndex) next next end function the entire thing processes in barely any noticeable time (basically close to 0). Why?

  • Retrieving Windows Mobile browser history

    - by kurige
    How can I retrieve a list of urls a user has visited on a Windows Mobile phone? I've written a program that successfully retrieves the visited urls in a user's cache, using FindFirstUrlCacheEntry and FindNextUrlCacheEntry - but as I understand it this is not the same as the user's actual web history. In any case it does not seem to give correct results. Edit: I believe the file I'm looking for is index.dat. But it's certainly not in the same place it is on a desktop machine, if it exists at all. And I'm not sure how to parse it. Any experience in this area would be greatly appreciated.

  • R: How can I use apply on rows of a data.frame and get out $column_name?

  • Persisting a single UISearchBar instance across 4 separate UITableViews

    - by Jacob Relkin
    Hi fellas, I'm in the midst of an iPhone app that needs to have 4 separate UITableView objects sharing access to one UISearchBar in the first section and first row of the aforementioned UITableView objects. I have tried to offset the UITableView's frame by 44 pixels, then adding the search bar as a subview of my UIViewController's view. That works, but I cannot use the table index to scroll up to the search bar, since it is not a cell in the tableview. I need to have the search bar in the table view itself. My goal is to have the same UISearchBar in the first section of multiple tableviews. Thanks so much.

    Hi, I am interested in the current byte position in the stream when parsing something using Antlr 3. I have seen there is a similar question but there was no real answer there. That is why I am trying again. I am not interested in token index, byte position in a line etc... Could you someone tell me that? It is obvious that some code has to be written/overridden. Does someone have specific code to write? I use C#.

  • 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!
