• Why can't I use the return from an insertAfter as a regular jQuery object?

  - by joachim

  I'm trying to insert a link after form elements to clear them. This demo code with headings doesn't work: h2 = $('h2'); clickytest = $('click me').insertAfter(h2).click(function() { $(this).append('foo'); }); But this does: clickytest = $('click me').insertAfter(h2); $('a.clicky').click(function() { $(this).append('foo'); }); The only difference is I've gone back and re-selected the new elements, rather than use what insertAfter returns. If on the other hand there is only one H2 in the whole document, then the first version works. What's going on? I've tried playing with each() but I'm not sure exactly what jQuery is doing here.

• website creation - for non web programmers?

  - by Tim

  I thought I would find decent questions and answers for this, but none really caught my eye... I am a C++ developer and I own a few domains. I'd like to start off with simple web sites for each with a minimum of time and fuss and minimum learning. I have too many projects going and don't have the time to learn how to build websites. One is for a company that currently has only a single product with custom development as well. I hacked together some really bad html with paypal links on it. It is just one simple product. I want to add uservoice to it and maybe some other stuff like FAQ, forums, etc. Right now I just link to a google group I created. Another is a startup in development phase, but we want to provide simple content like whitepapers and press releases and a section for investors. - mostly an "about us" type of thing. We will also be providing details about our product. Then there is a blog site - currently using godaddy's quickblogcast. Not a bad start but I suspect I want to move to something else. The question is - is there a framework that I can use that will make decent, if not outstanding, sites? Again, I have my hands full with three projects in addition to my day job and don't have time to learn web programming. I also don;t want to just pay a web person and then be out in the cold for upgrades, changes, etc. I have been burned before. I am happy with a web-based app or a desktop app that builds html or whatever and then I can ftp it up to the hosting servers. To summarize: - simple to get started - low time to get a web page going - ability to integrate with a few hand-done pages - pay pal integration - uservoice integration - ability to put under my svn would be nice too EDIT Thanks to the responders. I understand now why my original searches failed. I was not searching for "CMS". I'll go back and do that. I would expect that this is a many-times-duplicate... EDIT: I am considering using Wordpress and Drupal - one for each of the sites. I did one Drupal site quickly just so I could qualify for one of the Microsoft programs for discounted dev tools - anyway - it was a quick and dirty homepage and I am still on the learning curve. I look forward to playing with it. So far it has been ok. I am not sure about doing a taste-test between the two - might be a waste of time where I could just become that much better at Drupal faster than spending time on wordpress... Will keep updated. EDIT: Selecting the Drupal answer by slim for now. That is what I am going with. Don't have time to check them all out. Wordpress sounds like a good option too, but such limited time... Results: I have tried wordpress and drupal so far. Wordpress is great for blogging or for a site that you want to run ads from, but I disagree that it is ready for a corporate site, unless you want to spend lots of time making your own theme, etc. But if you spend that time, why not work with drupal? Drupal was a little intimidating at first - but after spending about 4 hours reading the overview and step-by-step guide online was a HUGE step. I got a simple site up and running easily after that. Trying to make a website just by going to the admin panel without reading anything is a waste of time. You really need to read the docs. The site is great. start here: http://drupal.org/getting-started I'd suggest drupal to anyone. It has amazing capabilities, lots of support and lots of users. Just doing blogging? Wordpress is really great for that. So now I've got two sites running with a lot of the functionality I wanted - and they look good. ONE MORE EDIT Well, I have switched back to wordpress after buying a theme and then getting help from web developers. I guess either one will work - it is just a matter of getting comfortable witht he basics, using the right tools and trying things out.

• How can you determine when the user scrolls to the bottom of a DataGridView?

  - by Craig

  I am writing a C# Windows Forms Application in Visual Studio 2008. I have a DataGridView with a lot of data in it. I would like to initially only populate 10,000 rows and add more only when the user scrolls to the bottom. I am handling the DataGridView's Scroll event, but it never seems to raise with the ScrollEventArgs.Type property set to Last, which is the condition I think I need to catch to add more rows. I have read about people having bad experiences with the DataGridView.Scroll event (e.g. http://stackoverflow.com/questions/785200/datagridview-scroll-event-and-scrolleventtype-endscroll), but the solution provided (http://stackoverflow.com/questions/472389/how-can-i-receive-the-scroll-box-type-scroll-events-from-a-datagridview/767603#767603) only adds the ScrollEventArgs.Type property to come back as EndScroll, not Last like I need. Does anybody know how to get the event to raise properly, or another way to accomplish this task?

• View Latest Comments Made

  - by Abs

  Hello all, I hope I can give feedback like this. It may be just me and others may have already suggested this but is there a way to view our recent comments in our account profiles? I mean I can see questions asked, questions answered etc. But there are loads of questions where I add a comment to the question asker and when I leave the site, I either have to remember what the question was to go back and check if anyone has posted anything. Simply, I think having a place where we can view our latest comments if not all our comments in the control panel/user area would be great! Thanks all

• Modifying setup file with PHP

  - by Paul Lammertsma

  I have an application that needs branding when downloaded in certain continents. When installed in North America, for instance, the application, when run, displays a different logo and company name than in Europe. The setup file is provided through a PHP script. Presently there is a Inno Setup executable for Windows and a DMG for Mac OS X. I have seen that when downloading Google Chrome, you can specify whether or not it should send usage statistics. A brief look at the JavaScript that controls it reveals that this is simply sent back to the server with &usagestats=0 or &usagestats=1. How would I go about influencing the installation based upon settings specified via the PHP download page?

• width of a frustum at a given distance from the near plane

  - by structolite

  I'm using CML to manage the 3D math in an OpenGL-based interface project I'm making for work. I need to know the width of the viewing frustum at a given distance from the eye point, which is kept as a part of a 4x4 matrix that represents the camera. My goal is to position gui objects along the apparent edge of the viewport, but at some distance into the screen from the near clipping plane. CML has a function to extract the planes of the frustum, giving them back in Ax + By + Cz + D = 0 form. This frustum is perpendicular to the camera, which isn't necessarily aligned with the z axis of the perspective projection. I'd like to extract x and z coordinates so as to pin graphical elements to the sides of the screen at different distances from the camera. What is the best way to go about doing it? Thanks!

• Background problem of opengl 3d object over iphone camera view

  - by user292127

  Hi, I'm loading opengl 3d objects over the iphone camera view. When opengl view is loaded it's loading with a opengl 3d object with black background. The black background color will block the camera view.I just want to clear background color of opengl view so that I could load only the 3d object to the camera view. I had tried glclearcolor(1.0,1.0,1.0,0.0); but no change to background color. I had also tried to clear background color opengl view using [glview setbackgroundColor:[UIColor clearColor]];. No change in back ground color. Can any one help me with this stuff ? I'm new to opengl. Thanks in advance

• How to fix weird scrolling/alignment behavior when using keyboard in MenuStrip?

  - by bentsai

  I started noticing strange behavior when navigating the main toolbar of my Winforms application, and I don't know how to fix it. When I initially open the dropdown of the File menu, it looks like this: I begin to scroll down each item with the arrow keys, and everything is fine until I reach "Exit". As soon as I hit the down arrow key from "Log Off", or if I hit the up arrow key from "Open", the menu rearranges itself to look like this: I'm puzzled by this behavior. The menu still works, and from this point, if I start scrolling up, I can get the arrangement back to normal: A few observations: The menu still works. This doesn't happen when using the mouse. I have some code that toggles the Visible property of some of the menu items. I was able to modify what the arrangement was by playing around with this, but it was still messed up. Can anyone help me understand what is going on, and how to fix it?

  Hi Everybody, i have a gridview control . When I change page of gridview control i get this error. Server Error in '/' Application. Failed to load viewstate.

• Figuring out if overflow:auto would have been triggered on a div

  - by jerrygarciuh

  Hi folks, // Major edit, sorry in bed with back pain, screwed up post One of the ad agencies I code for had me set up an alternate scrolling solution because you know how designers hate things that just work but aren't beautiful. The scrolling solution is applied to divs with overflow:hidden and uses jQuery's scrollTo(). So, this is married in places to their CMS. What I have not been able to sort yet is how to hide the scrolling UI when overflow:auto would not have been triggered by the CMS content. The divs have set heights and widths. Can i detect hidden content? Or measure the div contents' height? Any ideas? TIA JG

• wheel of fortune collision detection

  - by Andrew

  Hey, I have a wheel segmented into 8 pie pieces, and a picker that is pointing at the currently selected segment (think wheel of fortune). I want to highlight the currently selected segment, and so have started to use Chipmunk to construct the 8 segments, attached to a rotating body, and then the picker that is put in a position to collide with each of the segments. The trick is, how do you allow the picker to pass over top of the segments, while still getting the collision, but not actually colliding and slowing down the wheel? I haven't started down this path yet, but thought this may solve the problem: removing the colliding segment and then putting it back after the picker has started colliding with another segment a bit away (like two segments away). There may be a much simpler solution not even involving Chipmunk that I haven't thought of. Thanks, Andrew

• XStream or Simple

  - by Adeel Ansari

  I need to decide on which one to use. My case is pretty simple. I need to convert a simple POJO/Bean to XML, and then back. Nothing special. One thing I am looking for is it should include the parent properties as well. Best would be if it can work on super type, which can be just a marker interface. If anyone can compare these two with cons and pros, and which thing is missing in which one. I know that XStream supports JSON too, thats a plus. But Simple looked simpler in a glance, if we set JSON aside. Whats the future of Simple in terms of development and community? XStream is quite popular I believe, even the word, "XStream", hit many threads on SO. Thanks.

• Lucene search taking TOOO long.

  - by Josh Handel

  I;m using Lucene.net (2.9.2.2) on a (currently) 70Gig index.. I can do a fairly complicated search and get all the document IDs back in 1 ~ 2 seconds.. But to actually load up all the hits (about 700 thousand in my test queries) takes 5+ minutes. We aren't using lucene for UI, this is a datastore between processes where we have hundreds of millions of pre-cached data elements, and the part I am working on exports a few specific fields from each found document. (ergo, pagination doesn't make since as this is an export between processes). My question is what is the best way to get all of the documents in a search result? currently I am using a custom collector that does a get on the document (with a MapFieldSelector) as its collecting.. I've also tried iterating through the list after the collector has finished.. but that was even worse. I'm open to ideas :-). Thanks in advance.

• Django Haystack exact filtering

  - by blackrobot

  I have a haystack search which has the following SearchIndex: class GrantIndex(indexes.SearchIndex): """ This provides the search index for the Grant application. """ text = indexes.CharField(document=True, use_template=True) year = indexes.IntegerField(model_attr='year__year') date = indexes.DateField(model_attr='date') program = indexes.CharField(model_attr='program__area') grantee = indexes.CharField(model_attr='grantee') amount = indexes.IntegerField(model_attr='amount') site.register(Grant, GrantIndex) If I want to search filtering out any programs that ARE NOT 'Health', I run the following query: from haystack.query import SearchQuerySet sqs = SearchQuerySet() sqs = sqs.filter(program='Health') Unfortunately, this also produces objects from the program 'Health\Other' and 'Health\Cardiovascular'. How do I stop the search from allowing those other programs in? I run Ubuntu 9.10 with Xapian as my search back-end.

• solution on SP and EF & Ria Service

  - by KentZhou

  As EF 4.0 released, more support to SQL server Stored procedure. Complex Type can be generated automatically for result dataset of SP. But complex type not support by Ria Service. When I try to use ria service combined with EF 4.0, I want to get dataset by SP. This result is not mapped to any entity/table. Some sulutions suggested by community are: 1. Create view to map sp result. (but for EF, if there is no ID or primary, can't be map to any entity) 2. Create Entity to map sp result.(for this, you even need to map SP for CRUD even though I don't need CUD on this sp result) Also above solution can't be automated. As Database objects maybe changed with the time, auto update edm will lost above solution. So what's the solution? I want to put data operation back to DB as possible, so that many changes can be done in DB and no need to rebuild .net assemblies(this cause redeploy).

• Google Analytics API - Tying Behavior to Specific Dates

  - by DavidS

  I am using the API to understand the performance of Adwords ad campaigns. I need to know how to attribute metrics back to the date dimension. For instance, for a given date, if I have 20 clicks, 18 visits, and 3 goal completions, does it mean that: 1) All of these actions happened on the day in question and are otherwise independent (meaning that the 3 goals could have been for people that clicked any time in the past 30 days, not who clicked on that day) 2) The on-site actions are a subset of the click activity on that day (i.e. on that day, 20 people clicked, 18 registered a real visit, and 3 completed a goal) If it is scenario 2, does that mean there is a need to refresh old rows every day? Thanks!

• ASP.NET GridView and UpdatePanel

  - by Echilon

  I have a GridView, inside a UserControl, inside an UpdatePanel on a page. There's a button in the GridView which needs to fire a postback. What happens is: User clicks button - RowCommand Fires - Custom event is raised on UserControl - Page detects this and changes the active view index for a multiview and also the page title and some other controls outside the UpdatePanel. The problem is, the page posts back asyncchronously, the page title changes, but the actions requireing a full postback don't happen because a full postback doesn't occur. To register the button as a postback trigger I'm using: ImageButton btnResults = e.Row.FindControl("btnResults") as ImageButton; ScriptManager scrCurrent = ScriptManager.GetCurrent(this.Page); if (btnResults != null && scrCurrent != null) { scrCurrent.RegisterPostBackControl(btnResults); } I know this is a bit of a complicated problem, but I'd really appreciate any help.

• Why does IE8 change flash callback function into object?

  - by Christian Hollbaum

  Hi Guys I have put 2 swf's (using swfobject 2) on the same website; One for playing a movie, and one for controlling the movie (I want to position them seperately, so they can't be in the same swf). I'm doing the communication between the two using javascript with jQuery, and externalcallback functions in both swf's. Everything is running smoothly on all browsers, but IE8. In IE8 I can only call the pause callback function in the control swf once. When it has been called it will not run properly the next time. After trying to debug what is happening live, using javascript's "type of" I have found that IE8 changes the callback function on the flash object from a function into an object when it has been triggered. Can anyone explain why this is happening? .. and maybe suggest how to avoid this? .. or change the object back to a function?

• javascript return function's data as a file

  - by Dennis

  I have a function in javascript called "dumpData" which I call from a button on an html page as **onlick="dumpData(dbControl);"* What it does is return an xml file of the settings (to an alert box right now). I want to return it to the user as a file download. Is there a way to create a button when click will open a file download box and ask the user to save or open it? (sorta of like right-clicking and save target as)... Or can it be sent to a php file and use export();? Not sure how I would send a long string like that to php and have it simple send it back as a file download. Dennis

• Wrapper around bash, control STDIN and STDOUT

  - by blinry

  I would like to talk to a interactive bash process. Here is an example, so you know what I want to archieve: Program starts a new bash process. User types "ls" into my program. Program sends this command to the bash process. Program reads all available output of the bash (including the prompt) and displays it back to the user. GOTO 1 As you can guess, there is much room for nifty manipulations here and there... ;-) It would be wonderful if this also worked for subprocesses (started by the bash process) and curses-based programs. I would like to implement this functionality in Ruby, and already have experimented with IO.popen, but strange things happen. You are also welcome to do this in other languages.

• Looking to capture PageIndex on a gridview

  - by StevieB

  Hey, So I have a gridview which lists a bunch of jobs. On this gridview I have paging enabled, which works fine. When I hover over the Page Numbers i.e 1,2,3,4,.... the following is displayed javascript_DoPostBack('C100PlaceHolderGrievew','Page$1') Now my problem is as follows. When I click on one of the hyperlinks in this list i go to an edit details page. Once the user clicks on save I redirect the user back to the List page with gridview. What I would like to implement is that the gridview remembers what page they came from i.e Page 2. I know i can Use PageIndex to set this but Im not sure how to send across the value of "page" of the gridview so i can this.

• How do you implement Software Transactional Memory?

  - by Joseph Garvin

  In terms of actual low level atomic instructions and memory fences (I assume they're used), how do you implement STM? The part that's mysterious to me is that given some arbitrary chunk of code, you need a way to go back afterward and determine if the values used in each step were valid. How do you do that, and how do you do it efficiently? This would also seem to suggest that just like any other 'locking' solution you want to keep your critical sections as small as possible (to decrease the probability of a conflict), am I right? Also, can STM simply detect "another thread entered this area while the computation was executing, therefore the computation is invalid" or can it actually detect whether clobbered values were used (and thus by luck sometimes two threads may execute the same critical section simultaneously without need for rollback)?

• Looking for Eclipse plugin: Lock source tabs in place

  - by Fredrik

  When working with java code in Eclipse I can typically juggle between 20-40 different files, but there usually are just two that I actively work with at the time (test and code). Going back to the code where I want to work after having debugged through 5-10 classes can be a pain. So what I would like to do is to be able to right click on the tab of a class and choose to lock them in place. The classes would then always be available as the first and second tabs furthest to the left in the editor. All other classes (and other files opened in the editor) would then fight over the remaining space in the editor like today. Is there a plugin like this? My google-fu might not be strong enough, cause I find nothing.

• jQuery Address changed event

  - by Dustin

  I'm trying my hand at jQuery Address http://www.asual.com/jquery/address/ On a click event I set $.address.value(mypath); This fires off the $.address.change() event. When I click a link I want the behavior to be slightly different than when this event is fired by clicking the back/forward button or with a bookmark or link. Is there a way to distinguish between the two events. I've looked at the event object passed to $.address.change() and they seem to be identical in both situations.
