• How to set up Webtrends to segment paid search campaigns?

  - by hfidgen

  Hiya, I'm trying to learn how to set up Webtrends Analytics to segment paid search properly. I've dug up the fact that you need to pass "WT.srch=1" over in the url from the advert, but are there other parameters which you can use to segment: Campaign Adgroup Ad network I know you can do this with Google Analtics at the drop of a button using the various UTM tags, but Webtrends seems to use the proprietary WT. tags. Yet I can only find one tag... wtf :P Anyone able to help? Thanks! H

• How can I request an image and return it as black and white in rails?

  - by NotDan

  I'd like to have an image and a combo box with 2 options: color, and black and white. When the combo box selection changes, I'd like to return the image as black and white and have this done dynamically on the server (so I don't have to store the black and white image on the server). I was thinking I could point the img tag at a url like "/images/blackandwhite/120" where 120 is the image id of the color picture, and have it dynamically turn the image to black and white and return the image data to the browser. Is this possible? How would I do this?

• UI suggestions on how to display suggested tags for a given text to a user?

  - by Danny

  I am writing a web-app that uses a tagging system to organize the user's submitted reports. Part of it uses ajax to get suggestions for tags to present to the user based on the content of their report. I am looking for suggestions on how to present this information for the user. I'm not quite certain what a friendly way to do this would be. Edit: Well, most of the responses here seem to be focused on the user typing in keywords. The idea I'm trying to define here is more towards presenting the user a set of suggested keywords that they may accept or decline without having to type a tag in manually. (That option is of course still available to them) --------------------------- # say they can checkoff or select tags they like. | o[tag2] x[foo] o[moo] | | x[tag1] o[bar] | ---------------------------

• How to solve the performance decay of a VB.NET 1.1 application?

  - by marco.ragogna

  I have single-thread windows form application written with VB.NET and targeting Framework 1.1. The software communicates with external boards through a serial interface, and it mainly consist of a state machine that run some tests, driven in a loop done with a Timer and an Interval of 50ms. The feedback on the user interface is done through some custom events raised during the tests. The problem that is driving me crazy is that the performance slightly decrease over time, and in particular after 1200/1300 test operations. The memory occupied does not increase over time, it is only the CPU that seems interested by this problem. The strange thing is that, targeting framework 2.0 and using the same identical code, I do not have this problem. I know that is difficult without looking at the code, but do you have suggestions how can I approach the problem?

• [MFC] Combining 2 memory DCs ?

  - by OverTheEdge

  I'm writing a control where there's a lot of custom drawing going through. Because of this I need to trim down the amount of "screen writes" that go about. Currently there is only one memory DC that is used to write to screen so as to avoid flicker when the control is redrawn. I want to know if it is a possiblity to use 2 or more memory DCs to write updates independently and then bitblt them to screen. This way the need to render non-changed parts of the screen is minimized. thanx in advacne, the_Saint

• Response.Redirect in HttpModule

  - by AgentHunt

  Can I do a redirect to a custom page in an HttpModule? I have an HttpModule A which executes some javascript code when any aspx page is loaded. I would like to have a server side code check to see if the clients browsers supports cookies. Can I place that code in the HttpModule A? If so, in which event? Or do I need to have a new HttpHandler for both purposes? Also, is it possible to check for cookies in an HttpModule(without a response.redirect)? All solutions I have seen need 2 pages, 1 for setting the cookie and the other for checking if the cookie has actually been created. I am hoping there should be a way to check for cookies at one place. Thanks in advance

• How to access a plugin model from a regular controller in PHP Cake 1.1

  - by Duncan

  Hopefully a simple question: I've a plugin which uses a set of tables (kb_items, kb_item_tags, etc). and I'd like to be able to access these models from another controller (say, my Pages controller), thus: class PagesController extends AppController{ function knowledgebase(){ $items = $this->KbItem->findAll(...); } } I am admittedly breaking the rules a little (by not placing this controller inside the knowledge base plugin), but this in this case its a custom page that doesn't need to be part of the knowledge base plugin code base. Please let me know if you need more details. Thanks in advance for any help!

• How to order the images in a mysql database?

  - by user305270

  Hy! Here is my problem: i have a profile and this profile has for example 100 images. When someone visit this profile the first image will be the first result of my query that sorts by updated_at. But if the user would want to put the image with the (id = 8) to be the first, then (id = 22) then (id = 88) and so on? I need to put another field or is really necessary a new table to make a custom sort on images? and maybe someone explain this to me how to do? thanks, i appreciate your help ;)

• how to setup rails Authenticity Token to work with multiple domains?

  - by bwizzy

  I'm building an app that uses subdomains as account handles (myaccount.domain.com) and I have my sessions configured to work across the sub-domains like so: config.action_controller.session = {:domain => '.domain.com'} In addition to the subdomain a user can input a real domain name when they are creating their account. My Nginx config is setup to watch for *.com *.net etc, and this is working to serve out the pages. The problem comes when a site visitor submits a comment form on a custom domain that was input by the user. The code is throwing an "Invalid AuthenticityToken" exception. I'm 99% sure this is because the domain the user is on isn't specified as the domain in the config.action_controller.session. Thus the authenticity token isn't getting matched up because Rails can't find their session. So, the question is: Can you set config.action_controller.session to more than 1 domain, and if so can you add / remove from that value at runtime without restarting the app?

• ItemsControl that loads items one by one asynchronously.

  - by Vinit Sankhe

  Hey Guys, I am creating a custom DataGrid by deriving the traditional tookit based WPF DataGrid. I want a functionality in the grid to load items one by one asynchronously, wherein as soon as ItemsSource is changed i.e. a new collection is Set to the ItemsSource property or the bound collection is Changed dues to items that rae added, moved or removed (wherein the notifications comes to the data grid when the underlying source implements INotifyCollectionChanged such as ObservableCollection). This is because even with virtualising stackpanel underneath the datagrid takes time to load (2-3 seconds delay) to load the data rows when it has several columns and some are template based. With above behavior that delay would "appear" to have reduced giving datagrid a feel that it has the data and is responsive enough to load it. How can I achieve it? Thx Vinit.

Has anyone ever worked with something similar before? Any suggestions?!! Thanks in advance! --eureka

• Is there a SortedList<T> class in .net ? (not SortedList<Key,Value> which is actually a kind of Sort

  - by Brann

  I need to sort some objects according to their contents (in fact according to one of their properties, which is NOT the key and may be duplicated between different objects) .net provides two classes (SortedDictionnary and SortedList), and both are some kind of Dictionaries. The only difference (AFAIK) is that SortedDictionnary uses a binary tree to maintain its state whereas SortedList does not and is accessible via an index. I could achieve what I want using a List, and then using its Sort() method with a custom implementation of IComparer, but it wouldn't be time-efficient as I would sort the whole List each time I insert a new object, whereas a good SortedList would just insert the item at the right position. What I need is a SortedList class with a RefreshPosition(int index) to move only the changed (or inserted) object rather than resorting the whole list each time an object inside changes. Am I missing something obvious ?

• How to pre-check checkboxes in formtastic

  - by trustfundbaby

  I have a form I'm trying to set up ... Users can have many posts, and each post can have many people watching it. The Watch model is set up polymorphically as 'watchable' so it can apply to different types of models. It has a user_id, watchable_id, watchable_type and timestamps as attributes/fields. This is soley so that when people comment on a post, users watching the post can get an email about it. What I'm trying to do is show the user a list of users that they can tag on each post, which is not problem. This is what I'm using right now http://pastie.org/940421 The problem with this, is that when you go to edit an update/post ... all the checkboxes are prechecked ... I want it to pre-check only users who are currently watching the post.

• How can I use the same buildscript for Flash Builder 4 and Ant/Mvn?

  - by David Laing

  I'm setting up a build system for a Flash Builder 4 (Flex 4) based project; and I'm struggling to get a setup that compiles in the IDE the same as it does from the command line on the build server. I come from a C# background; and my expectation is that I'll be able to create a "solution" with a collection of "projects" that I can compile from the IDE, or from the command line on the build server. The best I've managed sofar is 2 separate build "scripts", a custom ant script for the build server, and the default Flash Builder IDE config based on a workspace; but this is making my DRY daemons jump around in fury. Please can someone point me in the right direction :)

Like adding custom AIs, path finding, etc. Xcong is an engine for turn-based strategy games.

• Cocoa Key event problem

  - by Oscar

  I'm trying to build my first cocoa application. done some iPhone developing before. I have a hard time understanding how to layout my project. i making a Pong game and my current design is to allocate an NSWindowController from my appDelegate. I then use custom view to act as paddles and ball. My problem is that i can't get the window controller to capture key events. Am i thinking wrong here? My idea is to have a controller class with all the logic, should i subclass another class for that?

• Best way to play MIDI sounds using C#

  - by jerhinesmith

  I'm trying to rebuild an old metronome application that was originally written using MFC in C++ to be written in .NET using C#. One of the issues I'm running into is playing the midi files that are used to represent the metronome "clicks". I've found a few articles online about playing MIDI in .NET, but most of them seem to rely on custom libraries that someone has cobbled together and made available. I'm not averse to using these, but I'd rather understand for myself how this is being done, since it seems like it should be a mostly trivial exercise. So, am I missing something? Or is it just difficult to use MIDI inside of a .NET application?

• Best way to return a user-generated file, AJAX or Forms?

  - by Bill Zimmerman

  Hi, I'm new to web programming, so I need some help. I am writing a custom file-creation app for my site. A user visits the page, clicks on some various options and toggles some checkboxes, and the presses a 'download now' link. I have a PHP backend which will be processing the submission, and generating a PDF file. After the user presses the download link, I want the download to start like it would for any static link. My question is: What is the best way to do this? From my limited understanding, I have a choice between using AJAX or somehow using forms to submit the data. What are the advantages/disadvantages of each? Does anyone have any good links to examples? Thanks

• jQuery: Preventing list scroll?

  - by Legend

  I have this scenario: Using an ajax query I fetch some data items and push them into a ul element as an li element. I use $("ulele").append(new_li_item). I wrote my own custom scroll for this ul element using the following whenever an event is detected: $("ulele").animate({scrollTop: '+=' + 200}, 'slow'); The problem is when I fire that event and the list scrolls due to the animate function above, I want to keep it stable for at least a few seconds. When it scrolls down, elements are still being pushed so the list keeps scrolling no matter what. Is there a way I can pause this from happening without really stopping the activity of pushing elements into the ul list?

• Pure HTML + JavaScript client side templating

  - by Dev er dev

  I want to have achieve something similar to Java Tiles framework using only client side technologies (no server side includes). I would like to have one page, eg layout.html which will contain layout definition. Content placeholder in that page would be empty #content div tag. I would like to have different content injected on that page based on url. Something like layout.html?content=main or layout.html?content=edit will display page with content replaced with main.html or edit.html. The goal is to avoid duplicating code, even for layout, and to compose pages without server-side templating. What approach would you suggest? EDIT: I don't need a full templating library, just a way to compose a pages, similar for what tiles do.

• Ruby on Rails - f.error_messages not showing up

• Solr dataimport skips entities in my data-config.xml

  - by lerhaupt

  My data-config.xml defines 3 different entities under the document tag (lets call them foo, bar and baz). When I issue a basic full import localhost:8983/solr/dataimport?command=full-import, only 2 of the 3 entities get indexed (foo and bar are in my index but baz never makes it). However, if I then issue a command to just import baz via localhost:8983/solr/dataimport?command=full-import&entity=baz&clean=false it adds baz documents just fine and the index then has all 3 types. Does anyone have any thoughts on why one entity gets skipped in the general data import but then still works okay if I specifically call it out? Is there an error/warning log I can check? Nothing bad shows up in /solr/logs/ but those just appear to be request logs.

• iPhone: how do I set up a clear window-size "blocker view"?

  - by Ben

  I feel like this should be obvious to me, but for some reason I can't figure this out. I have a navigation interface with nav bar, tool bar, and primary view. Sometimes the user takes an action that causes a progress indicator to appear in the middle of the view. While the progress indicator (which is a custom UIView) in spinning in the middle, I want no touch input to be allowed to go to any of the underlying interface (main view, nav bar, toolbar, etc). But this doesn't seem trivial. I've tried (and failed) to create a simple view whose only job is to swallow touch input and use it as a window subview-- no dice, it never gets the touch events (and yes, it does have userInteractionEnabled). I've tried to bolt it on as a transparent modal view controller, but those don't seem to ever be transparent. Thoughts? What am I missing? Thanks!
