  • Do i need a hashtag in Javascript to pass as a Div

    - by Mike
    How do i insert this php DivSomething into Javascript? Since Javascript needs a hashtag to recognize that as a div. Is there a way to tell JS that this is a Div or there's other better way to do it? Any help would be very much appreciated. <script> /*How do i insert a var DivSomething into JS with a hashtag */ /* DivSomething is php dynamic. It returns a Div. It can be #Div1, #Div2, #Div3... */ var DivSomething = '<?php echo $Highlight; ?>' $(function() { $('#MouseHere').hover(function() { $('#' + DivSomething).css('background-color', '#ffffff'); }, function() { // on mouseout, reset the background colour $('#' + DivSomething).css('background-color', ''); </script>

  • [.net] Treeview prevent Node collapse (weird problem)

    - by cssnoob
    Hey guyz! I have a .net 2.0 C# Project. I have a Treeview with 2 Nodes, each of them has many child nodes. When you click on a child node, a PDF is displayed in a webbrowser control depending on the properties of the node. Fine, but the problem is that when both Nodes are expanded, and I click on a child node, the other node gets collapsed! I don't have any code that collapses any node of the treeview, but somehow it happens! I also had a look at the BeforeCollapse Event, but somehow it doesn't fire, alltough the other node collapses! Can anyone imagine why this happens? I would be very grateful if anyone can teach me how to prevent this happening! Thank you very much!

  • best method in jquery for replacing rows in a table after server side processing such as mysql sorti

    - by Kevin J
    What is the 'best practice' when returning dynamic data for a table (server side sorting, filtering etc from a db) ? Do you return just the data in json, and repeatedly clone a row element, replacing the values in each row (thus decreasing the size of the ajax call, but increasing the client side processing), or return the full html, and replace with .html or .append? Or is there another method I'm missing? This is a frequent situation in my app, and in some cases a bottleneck, and I am unsure if what I am doing is the best solution. Currently, I return the row html and use a single .append call, after emptying all the rows except the header.

  • How to find selected node in Tree?

    - by badgirl
    Hello. I have dynamic tree (moreover nodes can have children). Every node has some action. When I right click on some node, it offers me some actions. One action, for example createChildNode creates child node, which in turn creates MyObject2. MyObject2 must be created with assistance of MyOject1, which was created in parent node(that one where I right click for actions ). How to get that object from selected node? That objects in nodes are putted to lookups.singleton(MyObjectX)

  • Find and list all functions/methods in a set of JavaScript files

    - by Dan Milstein
    Is there a way to read a set of JavaScript files, and output a description of where every function/method is defined? I realize that this is likely impossible in full generality, due to the extreme dynamic nature of the language. What I'm imagining is something which gets the (relatively) straightforward cases. Ideally, I'd want it figure out where, e.g. some method got attached to string or hash or some other fundamental class (and also just let you find all the classes/functions that get defined once in one place). Does such a tool exist?

  • Android png images big in memory

    - by taivo
    i have an application in android that has an imageflipper. Problem is, after about 8 images loaded to memory, i get an out of memory error. Well, i tried to do dynamic image loading, so that if the user flips 2 images, i'll load next 2 to memory and delete 2 first ones. It kind of works, but it ugly and i have trouble when user flips images back(imageflipper.showprevious()), i can't really shift all images and place new images to the beginning. My question is, is there a better way to do this kind of stuff? Resizing images didn't really help.

  • Where is the 'indeterminate type'?

    - by Daniel
    I'm defining the following type extension: type System.Reflection.MemberInfo with member x.GetAttribute<'T when 'T :> Attribute>(required, inherit') = match required, Attribute.GetCustomAttribute(x, typeof<'T>, inherit') with | true, null -> invalidOp (sprintf "Missing required attribute: %s" typeof<'T>.FullName) | _, attr -> attr :> 'T The last match expression (attr :> 'T) gives the error: The static coercion from Attribute to 'T involves an indeterminate type based on information prior to this program point. Static coercions are not allowed on some types. Further type annotations are needed. I've tried annotating the function return type, but got the same result. I would hate to change this to a dynamic cast. Is there a way to make the static cast work?

  • jQuery Animation and Classes

    - by ehdv
    Assume you have a list item, <li id="foo"> which you want to fade from one color to another when moused over, and that you are using jQuery. This is fairly easy: $('li#foo').bind('mouseenter' , function(e) { $(this).animate({backgroundColor: '#F00'} , 300); }); However, what if you wanted to get the resulting color or other style rules from a class defined in CSS without also declaring them in JavaScript? It seems there's no way to learn style information from CSS rules without having an example of the rule already in the document, which would require you to animate the <li> to the target appearance, then in the animation-finished callback, set the class which leads to redundant style declarations and can foul up your CSS at "runtime". Sorry if this question's unclear: It doesn't occur in the context of any specific project, I'm just curious how you'd go about this. Also, I know CSS3 hypothetically includes support for such transitions but using CSS for dynamic behavior like this seems such an ugly hack.

  • InvalidCastException: System.Web.UI.PartialCachingControl -> MyCustomControl when OutputCaching

    - by marcinn
    The problem: I am unable to use OutputCaching with my controls which derives from MyCustomControl. Controls are loaded dynamically using definitions from database with Page.LoadControl method. When I add to ascx <%@ OutputCache VaryByParam="*" Duration="3600"% the "InvalidCastException: System.Web.UI.PartialCachingControl - MyCustomControl" exception is thrown. I am unable to modify assembly witch contains dynamic loading controls logic. Is there any way to fix it in derived controls? The second question is about iis7 and native output caching - is it resolves this problem? (I tried to set up several performance counters and I saw that cache wasn't hit...)

  • Rendering HTML in rails without actually displaying it

    - by Kevin Whitaker
    Hello all, My current project requires me to assemble a .zip file containing HTML and text-only templates for a user to download, for importing into an email marketing program. I've inherited this project, and currently the code uses a "fake" model (that is a model that does not directly correlate to a database table), in which it stores the entire template in a string, using dynamic variables to populate certain areas. The "fake" model then has a method for creating a zip file. It seems to me that there has to be a better way to do this. I was wondering if there was a way to move the template into a .erb/haml file, and then write a method that would populate the file in preparation for being zipped up? Basically, is there a way to render an HTML and text file, without actually having to display them? Thanks for any help.

  • Where can I find an array of the Unicode code points for a particular block?

    - by gitparade
    At the moment, I'm writing these arrays by hand. For example, the Miscellaneous Mathematical Symbols-A block has an entry in hash like this: my %symbols = ( ... miscellaneous_mathematical_symbols_a => [(0x27C0..0x27CA), 0x27CC, (0x27D0..0x27EF)], ... ) The simpler, 'continuous' array miscellaneous_mathematical_symbols_a => [0x27C0..0x27EF] doesn't work because Unicode blocks have holes in them. For example, there's nothing at 0x27CB. Take a look at the code chart [PDF]. Writing these arrays by hand is tedious, error-prone and a bit fun. And I get the feeling that someone has already tackled this in Perl!

  • Having two backgrounds for an active menu item?

    - by HollerTrain
    Hi I have a dynamic menu where the ul li items change in width depending on the text set in the CMS (Joomla). They want the menu item, on mouse over, to both have 1. a repeated background image and 2. an image placed at the top (http://screencast.com/t/Zjk4YTJmNGQ). Now, I'm great with doing the repeated background image on a mouse over and that would be great, but I am not sure how to get both of these images in one css declaration. Any help would be greatly appreciated, as I haven't learned this technique yet :(

  • How to speed up a query?

    - by Soroush Khosravi
    I have a table that every request to the server, stores on it. For each request I will check that it is banned or not. For example it is a query: select * from requests where request_sessID = '4bc0331d983000902b4718c80f12e9b3' AND request_time > (UNIX_TIMESTAMP() - 3600) AND request_isEnable = 1 I also set the engine from InnoDB to MyISAM and row_format to Dynamic but nothing changed. My Hardware is very strong but it took about a minute to execute ! I am a programmer and newbie to mysql How can Speed Up this query? Thanks in Advance

  • generating an objectForKey from an array

    - by Brian
    I'm having success when I use this code to get a string from an array of file names called "fileList": cell.timeBeganLabel.text = [[[self.fileList objectAtIndex:[indexPath row]] lastPathComponent] stringByDeletingPathExtension]; so I expected the same code to generate the same string as a key for me in this: NSDictionary *stats = [thisRecordingsStats objectForKey:[[[self.fileList objectAtIndex:[indexPath row]] lastPathComponent] stringByDeletingPathExtension]]; cell.durationLabel.text = [stats objectForKey:@"duration"]; or this: NSDictionary *stats = [thisRecordingsStats objectForKey:@"%@",[[[self.fileList objectAtIndex:[indexPath row]] lastPathComponent] stringByDeletingPathExtension]]; Both build without error, and the log shows my data is there: but I'm getting a blank UILabel. Have I not written the dynamic key generator correctly?

  • Proper chart scaling in Reporting Services 2005

    - by lastas
    I'm developing a simple bar-chart in Reporting Services 2005 with a stored procedure as data-source. The values in this graph can be both positive and negative, and can span a very big range, and hence I cannot specify any non-dynamic scale that will work for all scenarios. The problem I'm facing is that the automatic scaling pretty much sucks. I get no line to show where the zero-point is, and the y-scale labels are from top to bottom: 8818 -191181 -391181 etc etc... So my question is, what is the best approach to make the scale more adapted to human reading? Is there any guide out there? Does reporting services 2008 handle this better? Also, moving away from Reporting Services is not really an option. I realize how to put values and expression in the max, min, and the gridline interval fields, although its more of a question what expressions I should put there.

  • MySql query and table optimisation

    - by Cheeky
    Hi everyone. I am trying to run the following simple query on a table with 500K records. SELECT COUNT(*) AS impressionCount FROM impression WHERE 0 = 0 AND impressionObjectId1 = 'C69A54B8-B828-E2E4-2319A93011DF4120' AND impressionObjectId2 = '1'; This query is taking 10 seconds to run. I have tried creating individual indexes for the impressionObjectId1 and impressionObjectId2 columns, as well as a composite index using both. The composite worked well for a while, but now it is also slow. Here is my table structure: DROP TABLE IF EXISTS `impression`; CREATE TABLE `impression` ( `impressionId` varchar(50) NOT NULL, `impressionObjectId1` varchar(50) NOT NULL, `impressionObjectId2` varchar(50) default NULL, `impressionStampDate` datetime NOT NULL, PRIMARY KEY (`impressionId`), KEY `IX_object` (`impressionObjectId1`,`impressionObjectId2`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1 ROW_FORMAT=DYNAMIC COMMENT='InnoDB free: 191488 kB'; Any advice would be greatly appreciated. Thanks EDIT: When adding an EXPLAIN, this is the output: 1, 'SIMPLE', 'impression', 'ref', 'IX_object', 'IX_object', '105', 'const,const', 304499, 'Using where; Using index'

  • Please help me get my content div to get an auto height from absolutely positioned element

    - by Justin Hollender
    I need some help with a CSS layout. It is set up like this: +--------------------+ | | | header | |-| |--------------| | |nav| content | | | | | | | | | | | | | | footer | +--------------------+ So, the nav is supposed to be floating above all the main page content. That's why I have it set to be absolutely positioned. The issue is that the nav items are dynamic, without a set height. Right now, the nav expands past the content. How can I fix it so that the content will have an auto height based off the nav? Thanks in advance.

  • "Refreshing" an XML feed on iPhone/Mac OSX

    - by Steve
    Hi all, I'm curious for those of you who are building iPhone apps based on REST/SOAP/XML-RPC or simply pulling down a dynamic XML feed, what does it mean exactly to you when a user says 'refresh' the feed? The straight forward way is to populate some collection, say an NSMutableArray, with whatever you bring down from the feed. If a widget on the UI is available to refresh, I typically do something like: [myMutableArray removeAllObjects]; // follow steps to repopulate myMutableArray It seems this is the least efficient algorithm for refreshing an XML feed. For instance many folks who are building Twitter clients, are appending changes to their existing feed, versus bringing down the entire feed in its complete form again. What kind of algorithms are you using to "refresh" your models when speaking to a server-side data source? Thanks all.

  • Is it possible to auto generate Getter/Setter from Array Values in PHP?

    - by Phill Pafford
    So I have a couple of arrays $array_1 = Array('one','two','three'); $array_2 = Array('red','blue','green'); Is there a dynamic way to create the Setters and Getters for an array with single value entries? So the class would be something like: class xFromArray() { } So the above if I passed $array_1 it would generate something like this: private $one; setOne($x) { $one = $x; } getOne() { return $one; } if I passed $array_2 it would generate something like this: private $red; setRed($x) { $red = $x; } getRed() { return $red; } So I would call it somehow like this? (My best guess but doesn't seem that this would work) $xFromArray = new xFromArray; foreach($array_1 as $key=>$data) { $xFromArray->create_function(set.ucfirst($data)($data)); echo $xFromArray->create_function(get.ucfirst($data)); }

  • Know if a Website project is recompiling itself in the background?

    - by jdk
    A number of team members update a central ASP.NET dev site (Website project, not a Web application type). Some kinds of changes cause a recompile/rebuild in it. The large website takes a while to recompile and we've noticed it will still seemingly serve out dynamic pages before everything is internally updated. During the site's "gestation" period, our mileage varies while hitting it. Sometimes we get a correct page, sometimes an compilation error page that will eventually be served up without a compilation error, and at other times an unexpected hybrid. Is it possible to query an ASP.NET website application to see if it's currently compiling or rebuilding itself? If so I would write a status page that the team could reference when they're getting weird behaviour, so they would know to wait.

  • Javascript for removing menu and scroll bars

    Hi - I have this script on my html page: parent.resizeTo(550,510); I'd like to add to it so it positions the window in the middle of the screen. Also, I want to remove the address and tool bars (I've managed to hide the scrollbars by using body{overflow:hidden;}). I know how to do this using JS upon opening a new window from the browser but this needs to work from clicking a link on a PDF. Does anyone have any suggestions? Thank you!

  • Starting out with Objective C; need some guidance

    Hi Everyone, I have started learning Objective C with no prior programming experience from the 'Become an X-Coder' eBook (http://download.cocoalab.com.s3.amazonaws.com/BecomeAnXcoder.pdf). My question is, if I want to be doing iPhone development, am I going in the right direction? Am I learning the wrong language, or should I be learning Cocoa Touch? As I said, I have no prior experience, and just need someone to point me in the right direction. Apoligies if I have put this in the wrong place. Thanks very much for your time.
