  • jquery png fix on hidden div and jquerybrowser question

    - by Jared
    Hello, I have some code that if Javascript is available, it will remove a GIF image and replace it with a PNG image. The PNG is display:none and the GIF is visible. Since IE6- browsers can't load PNG, I have loaded the jquery PNG fix. But it only seems to work if the image is already visible. The other issue is I am trying to get the jquery.browser function to apply to less than version 6, and I am not having much luck. <script type="text/javascript"> $(document).ready(function(){ $("#gif").hide(); jQuery.each(jQuery.browser, function(i, val) { if($.browser.msie && jQuery.browser.version <="6"){ $("#png").show(); $('.png').pngFix() }else{ $("#png").fadeIn("slow"); } }); }); </script> HTML <img class="png" id="png" src="images/main_elements/one-2-flush-it-campus-challenge.png" style="display:none;" /> <img id="gif" src="images/main_elements/one-2-flush-it-campus-challenge.gif"/>

  • Stack Overflow works best with JavaScript enabled banner

    - by carpenter
    I am trying to mimic this site's Javascipt required banner, and have the below divs which are being hidden if javascript is allowed/enabled, but I am getting a flash/glimps of it on page load. <div id="Main_noJS">Craftystuff.com works best with JavaScript enabled</div> <div id="PartOfMain_noJS"><br /></div> CSS: #Main_noJS { width: 100%; height: 23px; font-family: Arial; font-size: 111%; color: White; font-weight: bold; background: #AE0000; text-align: center; padding-top: 4px; position: fixed; z-index: 100; } JavaScript: // hide the "Craftystuff.com works best with JavaScript enabled" banner, if JavaScript is working if ($("#Main_noJS")) { $("#Main_noJS").hide(); // hide the spacer between the main content and banner... $("#PartOfMain_noJS").hide(); } So the banner is visible to start with, and only when javascript is enabled do I hide it but javascript must take a second to get to work to hide things... I would like to try to stop the glimps of the banner, when the page first loads, any help?

  • Linker flags for one library break loading of another

    - by trevrosen
    I'm trying to use FMOD and HTTPriot in the same app. FMOD works fine until I add in linker flags for HTTPriot, at which point I get a bunch of linking errors wherein FMOD is complaining about undefined symbols. In other words, adding in linker flags for HTTPriot seems to break the loading of FMOD's library. These are the kinds of errors I'm getting, all coming during the linking phase of my build: Undefined symbols: "_FMOD_Sound_Lock", referenced from: -[FMODEngine recordedSoundAsNSData] in FMODEngine.o -[FMODEngine writeRecordingToDiskWithName:] in FMODEngine.o "_FMOD_MusicSystem_PrepareCue", referenced from: -[FMODEngine addCue:] in FMODEngine.o These are the linker flags for HTTPriot: -lhttpriot -lxml2 -ObjC -all_load I added those as well as a path to the HTTPriot SDK per the instructions here: http://labratrevenge.com/httpriot/docs/iphone-setup.html I was hoping someone could enlighten me on why adding linker flags for one library might cause a failure of another to load. If I DON'T have these flags in, HTTPriot and FMOD both work fine on the simulator, but HTTPriot has runtime errors on the device, I assume because its libraries are not linked. FMOD works fine on the device though. I placed header search paths and library search paths in my build settings in order for XCode to find FMOD. That seemed to be OK until I tried adding these HTTPriot linker flags. I also tried adding a linker flag for the FMOD library (-lfmodex), but I get the same errors as I do without it.

  • Returned JSON from Twitter and displaying tweets using FlexSlider

    - by Trey Copeland
    After sending a request to the Twitter API using geocode, I'm getting back a json response with a list of tweets. I then that into a php array using json_decode() and use a foreach loop to output what I need. I'm using flex slider to show the tweets in a vertical fashion after wrapping them in a list. So what I want is for it to only show 10 tweets at a time and scroll through them infinitely like an escalator. Here's my loop to output the tweets: foreach ($tweets["results"] as $result) { $str = preg_replace('/[^\00-\255]+/u', '', $result["text"]); echo '<ul class="slides">'; echo '<li><a href="http://twitter.com/' . $result["from_user"] . '"><img src=' . $result["profile_image_url"] . '></a>' . $str . '</li><br /><br />'; echo '</ul>'; } My jQuery looks like this as of right now as I'm trying to play around with things: $(window).load(function() { $('.flexslider').flexslider({ slideDirection: "vertical", start: function(slider) { //$('.flexslider .slides > li gt(10)').hide(); }, after: function(slider) { // current.sl } }); }); Non-Working demo here - http://macklabmedia.com/tweet/

  • Google App Engine - Caching generated HTML

    - by Alexander
    I have written a Google App Engine application that programatically generates a bunch of HTML code that is really the same output for each user who logs into my system, and I know that this is going to be in-efficient when the code goes into production. So, I am trying to figure out the best way to cache the generated pages. The most probable option is to generate the pages and write them into the database, and then check the time of the database put operation for a given page against the time that the code was last updated. Then, if the code is newer than the last put to the database (for a particular HTML request), new HTML will be generated and served, and cached to the database. If the code is older than the last put to the database, then I will just get the HTML direct from the database and serve it (therefore avoiding all the CPU wastage of generating the HTML). I am not only looking to minimize load times, but to minimize CPU usage. However, one issue that I am having is that I can't figure out how to programatically check when the version of code uploaded to the app engine was updated. I am open to any suggestions on this approach, or other approaches for caching generated html. Note that while memcache could help in this situation, I believe that it is not the final solution since I really only need to re-generate html when the code is updated (as opposed to every time the memcache expires). Kind Regards, and thank you in advance for any suggestions you may be able to offer. -Alex

  • XMLStreamReader and a real stream

    - by Yuri Ushakov
    Update There is no ready XML parser in Java community which can do NIO and XML parsing. This is the closest I found, and it's incomplete: http://wiki.fasterxml.com/AaltoHome I have the following code: InputStream input = ...; XMLInputFactory xmlInputFactory = XMLInputFactory.newInstance(); XMLStreamReader streamReader = xmlInputFactory.createXMLStreamReader(input, "UTF-8"); Question is, why does the method #createXMLStreamReader() expects to have an entire XML document in the input stream? Why is it called a "stream reader", if it can't seem to process a portion of XML data? For example, if I feed: <root> <child> to it, it would tell me I'm missing the closing tags. Even before I begin iterating the stream reader itself. I suspect that I just don't know how to use a XMLStreamReader properly. I should be able to supply it with data by pieces, right? I need it because I'm processing a XML stream coming in from network socket, and don't want to load the whole source text into memory. Thank you for help, Yuri.

  • log4js ConsoleAppender initialization

    - by perrierism
    I'm wondering if anyone happens to have some experience using Log4js? It seems its normal ConsoleAppender isn't always ready to use immediately after it's added to a logger object... If I have two sequential script tags in a document like: //Initialize logger <script type="text/javascript"> var logger = new Log4js.getLogger("JSLOG"); logger.addAppender(new Log4js.ConsoleAppender(logger, false)); logger.setLevel(Log4js.Level.INFO); </script> //Use logger <script type="text/javascript"> logger.info('Test test'); </script> ... It causes the console pop-up (pop-up window) to appear with an error message on page load: 12:58:23 PM WARN Log4js - Could not run the listener function () { return fn.apply(object, arguments); }. TypeError: this.outputElement is null The console is still initialised, it's there afterward, but for just that first logger call it doesn't seem to be there fully. If I make the first logger call setTimeout("logger.info('test test')", 1000), it doesn't have the error. So it's like it's not ready immediately. Anyone see this before or know what a workaround might be? Cheers

  • Display a tree dijit using zend framework

    - by churris43
    I am trying to display a tree of categories and subcategories by using dijits with zend framework. Haven't been able to find a good example. This is what I've got: Basically I got the following code as my action: class SubcategoriesController extends Zend_Controller_Action{ ..... public function loadtreeAction() { Zend_Dojo::enableView($this->view); Zend_Layout::getMvcInstance()->disableLayout(); //Creating a sample tree of categories and subcategories $a["cat1"]["id"] = "id1"; $a["cat1"]["name"] = "Category1"; $a["cat1"]["type"] = "category"; $subcat1 = array("id" => "Subcat1","name" => "Subcategory1" , "type" => "subcategory"); $subcat2 = array("id" => "Subcat12","name" => "Subcategory12" , "type" => "subcategory"); $a["cat1"]["children"] = array($subcat1,$subcat2); $treeObj = new Zend_Dojo_Data('id', $a); $treeObj->setLabel('name'); $this->view->tree = $treeObj->toJson(); } .... } And on my view: <?php $this->dojo()->requireModule('dojo.data.ItemFileReadStore'); $this->dojo()->requireModule('dijit.Tree'); $this->dojo()->requireModule('dojo.parser'); ?> <div dojoType="dojo.data.ItemFileReadStore" url="/Subcategories/loadtree" jsId="store"></div> <div dojoType="dijit.tree.ForestStoreModel" jsId="treeModel" store="store" rootId="root" rootLabel="List of Categories" childrenAttrs="children" query="{type:'category'}"></div> <div dojoType="dijit.Tree" model="treeModel" labelAttrs="ListOfCategories"></div> It doesn't even seem to try to load the tree at all. Any help is appreciated

  • jQuery event handling with .live() problem with setInterval and clearInterval

    - by Kyle Lafkoff
    jQuery 1.4.2: I have an image. When the mouseover event is triggered, a function is executed that runs a loop to load several images. On the contrary, the mouseout event needs to set the image back to a predetermined image and no longer have the loop executing. These are only for the images with class "thumb": $("img.thumb").live("mouseover mouseout", function(event) { var foo = $(this).attr('id'); var wait; var i=0; var image = document.getElementById(foo); if (event.type == 'mouseover') { function incrementimage() { i++; image.src = 'http://example.com/images/file_'+i+'.jpg'; if(i==30) {i=0;} } wait = setInterval(incrementimage,500); } else if (event.type == 'mouseout') { clearInterval (wait); image.src = 'http://example.com/images/default.jpg'; } return false; }); When I mouseout, the image is set to the default.jpg but the browser continues to loop though the images. It will never stop. Can someone hit me with some knowledge? Thanks.

  • WCF and ASP.NET - Server.Execute throwing object reference not set to an instance of an object

    - by user208662
    Hello, I have an ASP.NET page that calls to a WCF service. This WCF service uses a BackgroundWorker to asynchronously create an ASP.NET page on my server. Oddly, when I execute the WCF Service [OperationContract] [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.WrappedRequest, RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)] public void PostRequest(string comments) { // Do stuff // If everything went o.k. asynchronously render a page on the server. I do not want to // block the caller while this is occurring. BackgroundWorker myWorker = new BackgroundWorker(); myWorker.DoWork += new DoWorkEventHandler(myWorker_DoWork); myWorker.RunWorkerAsync(HttpContext.Current); } private void myWorker_DoWork(object sender, DoWorkEventArgs e) { // Set the current context so we can render the page via Server.Execute HttpContext context = (HttpContext)(e.Argument); HttpContext.Current = context; // Retrieve the url to the page string applicationPath = context.Request.ApplicationPath; string sourceUrl = applicationPath + "/log.aspx"; string targetDirectory = currentContext.Server.MapPath("/logs/"); // Execute the other page and load its contents using (StringWriter stringWriter = new StringWriter()) { // Write the contents out to the target url // NOTE: THIS IS WHERE MY ERROR OCCURS currentContext.Server.Execute(sourceUrl, stringWriter); // Prepare to write out the result of the log targetPath = targetDirectory + "/" + DateTime.Now.ToShortDateString() + ".aspx"; using (StreamWriter streamWriter = new StreamWriter(targetPath, false)) { // Write out the content to the file sb.Append(stringWriter.ToString()); streamWriter.Write(sb.ToString()); } } } Oddly, when the currentContext.Server.Execute method is executed, it throws an "object reference not set to an instance of an object" error. The reason this is so strange is because I can look at the currentContext properties in the watch window. In addition, Server is not null. Because of this, I have no idea where this error is coming from. Can someone point me in the correct direction of what the cause of this could be? Thank you!

  • Is there a java library / package analogous to <stdio.h>?

    - by Roboprog
    I have been doing Java on and off for about 14 years, and almost nothing else the last 6 years or so. I really hate the java.io package -- its legion of subclasses and adapters. I do like exceptions, rather than having to always poll "errno" and the like, but I could surely live without declared exceptions. Is there anything that functions like the Unix/ANSI stdio.h routines in C? I know we will never be rid of java.io and its conventions until java itself is retired, as they have metastasized throughout the many frameworks that have accreted to java. That said, I would like something that works kind of like this (let's call it package javax.stdio): Have a main utility class, perhaps FileStar, that can read and write files (or pipes), either text or binary, either sequentially or random access, with constructors that mimic fopen() and popen(). This class should have a load of useful methods that do things like fread(), fwrite(), fgets(), fputs(), fseek(), and whatever else (fprintf()?). Methods that are incompatible with the open/construct mode simply throw up (just like some of the collections classes/methods do when restricted). Then, have a bunch of interfaces that suggest how you intend to use the stream once you have created it: Sequential, RandomAccess, ReadOnly, WriteOnly, Text, Binary, plus combinations of these that make sense. Perhaps even have methods to return the appropriate type-cast (interface), throwing up if you have asked for something incompatible. For extra flavor, skip the declared exceptions -- e.g. - javax.stdio.IOException extends RuntimeException. Is there an open source project like this floating around?

  • Is it possible to run PHPUnit with a dynamically loaded extension library?

    - by therefromhere
    I have a suite of PHPUnit tests for my extension, and I want to run them as part of the extension's Hudson build process. So I want to run PHPUnit specifying the extension library to load at runtime, but I can't figure out how to do this. My directory structure is as follows: /myextension.c /otherextensionfiles.* /modules/myextension.so /tests/unittests.php I've tried running PHPUnit with an configuration XML file as follows: <phpunit> <php> <ini name="extension_dir" value="../modules/"/> <ini name="extension" value="myextension.so"/> </php> </phpunit> And then running it as follows (from the tests directory): phpunit --configuration config.xml unittests.php But then I get Fatal error: Call to undefined function myfunction(), so it's not loading the library. I've also tried: phpunit -d extension_dir=../modules/ -d extension=myextension.so unittests.php And also dl('myextension.so') to the test setup, but no joy. If it's relevant, this is using PHP 5.2 and PHPUnit 3.4.11.

  • NHibernate IQueryable Collection as Property of Root

    - by Khalid Abuhakmeh
    Hello and thank you for taking the time to read this. I have a root object that has a property that is a collection. For example : I have a Shelf object that has Books. // now public class Shelf { public ICollection<Book> Books {get; set;} } // want public class Shelf { public IQueryable<Book> Books {get;set;} } What I want to accomplish is to return a collection that is IQueryable so that I can run paging and filtering off of the collection directly from the the parent. var shelf = shelfRepository.Get(1); var filtered = from book in shelf.Books where book.Name == "The Great Gatsby" select book; I want to have that query executed specifically by NHibernate and not a get all to load a whole collection and then parse it in memory (which is what currently happens when I use ICollection). The reasoning behind this is that my collection could be huge, tens of thousands of records, and a get all query could bash my database. I would like to do this implicitly so that when NHibernate sees and IQueryable on my class it knows what to do. I have looked at NHibernates Linq provider and currently I am making the decision to take large collections and split them into their own repository so that I can make explicit calls for filtering and paging. Linq To SQL offers something similar to what I'm talking about.

  • VS2010 express beta2 - no add reference dialog, no open file/project dialogs

    - by David
    Just installed VS2010 express for Windows Phone last night. Install went smoothly. It creates a project, compiles, and deploys the app to the emulator. Here's the problem: When I try to "Add Reference" through the Project menu, I do not get the Add Reference dialog box. Same thing if I right click References in the solution explorer and click Add Reference. That's not all. "File...Open" and "File...Open Project" also fail to throw up an open file dialog box. When attempting any of these actions, the IDE quickly loses and regains focus. Even pressing a keyboard shortcut (Ctrl+O) causes the IDE to quickly lose and regain focus, but no open file dialog box appears. This is what I have tried, not particularly in this order: 1. Turned off UAC 2. Monitored file and registry access using Process Monitor during a File...Open operation. File activity showed mostly "SUCCESS" with a few "FAST IO DISALLOWED" and a few "INVALID DEVICE REQUEST" results. Registry activity showed mostly "SUCCESS" with some "NAME NOT FOUND" and a few "BUFFER OVERFLOW" results. 3. Created a new, clean Windows account to run the IDE from 4. Forced a test project to add a reference to "System.Xml.Linq" by editing the ".csproj" project file. Project failed to load in the IDE. I don't have these problems at all on 2 other Windows 7 computers with VS2010 C# express beta 2 installed. One machine is 32bit and the other 64bit, both Home Premium edition. My system: Windows 7 Home Premium, 64bit Other Visual Studio products installed: VS2008 C# express, VS2008 C++ express One other thing to note: Several months ago I installed the non-phone distribution of VS2010 C# express beta 2, and I had the same exact problems. Back then I chalked it up to being beta and went back to VS2008 C# express, where I do not have these issues.

  • Castle Active Record - Working with the cache

    - by David
    Hi All, im new to the Castle Active Record Pattern and Im trying to get my head around how to effectivley use cache. So what im trying to do (or want to do) is when calling the GetAll, find out if I have called it before and check the cache, else load it, but I also want to pass a bool paramter that will force the cache to clear and requery the db. So Im just looking for the final bits. thanks public static List<Model.Resource> GetAll(bool forceReload) { List<Model.Resource> resources = new List<Model.Resource>(); //Request to force reload if (forceReload) { //need to specify to force a reload (how?) XmlConfigurationSource source = new XmlConfigurationSource("appconfig.xml"); ActiveRecordStarter.Initialize(source, typeof(Model.Resource)); resources = Model.Resource.FindAll().ToList(); } else { //Check the cache somehow and return the cache? } return resources; } public static List<Model.Resource> GetAll() { return GetAll(false); }

  • ASP.NET UpdatePanel > Get selected value from checbox list outside of panel

    Hi, I have a listing in an UpdatePanel I have some filters for that list in the form a checkboxList control. The checkboxList is created dynamically on page load During the Ajax update (postback), the checkbox list is not populated form the viewstate, so I cannot get the listing to filter. Note: If I put the checkbox list items directly in the markup, it all works, just not if the listing is populated on-postback. protected override void OnLoad(EventArgs e) { if (!Page.IsPostBack) { foreach (var p in global.Product) CheckListManufacurer.Items.Add(new ListItem(p, p)); } base.OnLoad(e); } <form id="ProductListForm" runat="server"> <asp:ScriptManager ID="ScriptManager" runat="server" EnablePartialRendering="true"></asp:ScriptManager> <asp:CheckBoxList ID="CheckListManufacurer" runat="server" EnableViewState="true"> <asp:ListItem Value="" Text="(All)"></asp:ListItem> </asp:CheckBoxList> <asp:Button id="btnTestAjax" runat="server" Text="Test" /> <asp:UpdatePanel ID="ProductsPanel" runat="server" UpdateMode="Conditional"> <Triggers> <asp:AsyncPostBackTrigger ControlID="btnTestAjax" /> <asp:AsyncPostBackTrigger ControlID="CheckListManufacurer" /> </Triggers> <ContentTemplate> <sr:ProductList ID="Products" runat="server" /> </ContentTemplate> </asp:UpdatePanel> </form>

  • Ruby script/console and Ruby script/server using two different DBs?

    - by aronchick
    Has anyone seen where script/console and script/server load two different databases (though both report using the same)? Here's the first output $ script/server => Booting WEBrick => Rails 2.3.5 application starting on http://0.0.0.0:3000 => Call with -d to detach => Ctrl-C to shutdown server [2010-03-21 15:54:05] INFO WEBrick 1.3.1 [2010-03-21 15:54:05] INFO ruby 1.8.7 (2010-01-10) [i386-mingw32] [2010-03-21 15:54:05] INFO WEBrick::HTTPServer#start: pid=7148 port=3000 No errors.

  • Just messed up a server misusing chown, how to execute it correctly?

    - by Jack Webb-Heller
    Hi! I'm moving from an old shared host to a dedicated server at MediaTemple. The server is running Plesk CP, but, as far as I can tell, there's no way via the Interface to do what I want to do. On the old shared host, running cPanel, I creative a .zip archive of all the website's files. I downloaded this to my computer, then uploaded it with FTP to the new host account I'd set up. Finally, I logged in via SSH, navigated to the directory the zip was stored in (something like var/www/vhosts/mysite.com/httpdocs/ and ran the unzip command on the file sitearchive.zip. This extracted everything just the fine. The site appeared to work just fine. The problem: When I tried to edit a file through FTP, I got Error - 160: Permission Denied. When I Get Info for the file I'm trying to edit, it says the owner and group is swimwir1. I attemped to use chown at this point to change owner - and yes, as you may be able to tell, I'm a little inexperienced in SSH ;) luckily the server was new, since the command I ran - chown -R newuser / appeared to mess a load of stuff up. The reason I used / on the end rather than /var/www/vhosts/mysite.com/httpdocs/ was because I'd already cded into their, so I presumed the / was relative to where I was working. This may be the case, I have no idea, either way - Plesk was no longer accessible, although Apache and things continued to work. I realised my mistake, and deciding it wasn't worth the hassle of 1) being an amateur and 2) trying to fix it, I just reprovisioned the server to start afresh. So - what do I do to change the owner of these files correctly? Thanks for helping out a confused beginner! Jack

  • Delphi access violation assigning local variable

    - by Justin
    This seems like the simplest thing in the world and I'm ready to pull my hair out over it. I have a unit that looks like this ; Unit myUnit; // ... //normal declarations //... Public //bunch of procedures including Procedure myProcedure; const //bunch of constants var //bunch of vars including myCounter:integer; Implementation Uses //(all my uses) // All of my procedures including Procedure myProcedure; try // load items from file to TListBox - this all works except on EReadError do begin // handle exception end; end; //try myCounter:=0; // <-- ACCESS VIOLATION HERE while myCounter //...etc It's a simple assignment of a variable and I have no idea why it is doing this. I've tried declaring the variable local to the unit, to the procedure, globally - no matter where I try to do it I can't assign a value of zero to an integer, declared anywhere, within this procedure without it throwing an access violation. I'm totally stumped. I'm calling the procedure from inside a button OnClick handler from within the same unit, but no matter where I call it from it throws the exception. The crazy thing is that I do the exact same thing in a dozen other places in units all over the program without problems. Why here? I'm at a total loss.

  • Problem with RVM and gem that has an executable

    - by djhworld
    Hi there, I've recently made the plunge to use RVM on Ubuntu. Everything seems to have gone swimmingly...except for one thing. I'm in the process of developing a gem of mine that has a script placed within its own bin/ directory, all of the gemspec and things were generated by Jeweler. The bin/mygem file contains the following code: - #!/usr/bin/env ruby begin require 'mygem' rescue LoadError require 'rubygems' require 'mygem' end app = MyGem::Application.new app.run That was working fine on the system version of Ruby. Now...recently I've moved to RVM to manage my ruby versions a bit better, except now my gem doesn't appear to be working. Firstly I do this: - rvm 1.9.2 Then I do this: - rvm 1.9.2 gem install mygem Which installs fine, except...when I try to run the command for mygem mygem I just get the following exception: - daniel@daniel-VirtualBox:~$ mygem <internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- mygem (LoadError) from <internal:lib/rubygems/custom_require>:29:in `require' from /home/daniel/.rvm/gems/ruby-1.9.2-p136/gems/mygem-0.1.4/bin/mygem:2:in `<top (required)>' from /home/daniel/.rvm/gems/ruby-1.9.2-p136/bin/mygem:19:in `load' from /home/daniel/.rvm/gems/ruby-1.9.2-p136/bin/mygem:19:in `<main>'mygem NOTE: I have a similar RVM setup on MAC OSX and my gem works fine there so I think this might be something to do with Ubuntu?

  • FormMethod.Get and query string parameters

    - by parminder
    Hi Experts, I am working on a website in asp.net mvc. I have to show a view where user put some search values like tags and titles to search. I want to use the same Index method for that. I have make my form to use formMethod.Get to send the parameters as querystring. so here is the method [HttpGet] public ActionResult Index(string title, string tags, int? page) { if (string.IsNullOrEmpty(title) return View(null); var list = GetSomeData(); return View(list); } here is my view <div id="searchBox"> <% using (Html.BeginForm(null, null, FormMethod.Get)) { %> <table> <tr> <td> <input type="hidden" id="isPosted" name="isPosted" value="1" /> I am looking for <%=Html.TextBox("Title")%> Tags: <%=Html.TextBox("Tags")%> <input id="search" type="submit" value="Search" /> </td> </tr> </table> <% } %> So when the user first visit the page, he will see only two text boxs and a button. but when he types something in the title and tags and click the search button i will load the view with some data. Now the problem is when i type something in title and tags box and click search, they are received in the method, but are not visible in the url. Is there anything i m doing wrong. help will be appreciated. Regards Parminder

  • rpy2: Converting a data.frame to a numpy array

    - by Mike Dewar
    I have a data.frame in R. It contains a lot of data : gene expression levels from many (125) arrays. I'd like the data in Python, due mostly to my incompetence in R and the fact that this was supposed to be a 30 minute job. I would like the following code to work. To understand this code, know that the variable path contains the full path to my data set which, when loaded, gives me a variable called immgen. Know that immgen is an object (a Bioconductor ExpressionSet object) and that exprs(immgen) returns a data frame with 125 columns (experiments) and tens of thousands of rows (named genes). robjects.r("load('%s')"%path) # loads immgen e = robjects.r['data.frame']("exprs(immgen)") expression_data = np.array(e) This code runs, but expression_data is simply array([[1]]). I'm pretty sure that e doesn't represent the data frame generated by exprs() due to things like: In [40]: e._get_ncol() Out[40]: 1 In [41]: e._get_nrow() Out[41]: 1 But then again who knows? Even if e did represent my data.frame, that it doesn't convert straight to an array would be fair enough - a data frame has more in it than an array (rownames and colnames) and so maybe life shouldn't be this easy. However I still can't work out how to perform the conversion. The documentation is a bit too terse for me, though my limited understanding of the headings in the docs implies that this should be possible. Anyone any thoughts?

  • cocoa hello world screensaver

    - by RW
    I have been studying NSView and as such I thought I would give a shot at a screen saver. I have been able to display and image in an NSView but I can't seen to modify this example code to display a simple picture in ScreenSaverView. http://www.mactech.com/articles/mactech/Vol.20/20.06/ScreenSaversInCocoa/ BTW great tutorial that works with Snow Leopard. I would think to simply display an image I would need something that looked like this... What am I doing wrong? // // try_screensaverView.m // try screensaver // #import "try_screensaverView.h" @implementation try_screensaverView - (id)initWithFrame:(NSRect)frame isPreview:(BOOL)isPreview { self = [super initWithFrame:frame isPreview:isPreview]; if (self) { [self setAnimationTimeInterval:1]; //refresh once per sec } return self; } - (void)startAnimation { [super startAnimation]; NSString *path = [[NSBundle mainBundle] pathForResource:@"leaf" ofType:@"JPG" inDirectory:@""]; image = [[NSImage alloc] initWithContentsOfFile:path]; } - (void)stopAnimation { [super stopAnimation]; } - (void)drawRect:(NSRect)rect { [super drawRect:rect]; } - (void)animateOneFrame { ////////////////////////////////////////////////////////// //load image and display This does not scale the image NSRect bounds = [self bounds]; NSSize newSize; newSize.width = bounds.size.width; newSize.height = bounds.size.height; [image setSize:newSize]; NSRect imageRect; imageRect.origin = NSZeroPoint; imageRect.size = [image size]; NSRect drawingRect = imageRect; [image drawInRect:drawingRect fromRect:imageRect operation:NSCompositeSourceOver fraction:1]; } - (BOOL)hasConfigureSheet { return NO; } - (NSWindow*)configureSheet { return nil; } @end

  • Getting "" at the beginning of my XML File after save()

    - by Remy
    I'm opening an existing XML file with c# and I replace some nodes in there. All works fine. Just after I save it, I get the following characters at the beginning of the file:  (EF BB BF in HEX) The whole first line: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> The rest of the file looks like a normal XML file. The simplified code is here: XmlDocument doc = new XmlDocument(); doc.Load(xmlSourceFile); XmlNode translation = doc.SelectSingleNode("//trans-unit[@id='127']"); translation.InnerText = "testing"; doc.Save(xmlTranslatedFile); I'm using a C# WinForm Application. With .NET 4.0. Any ideas? Why would it do that? Can we disable that somehow? It's for Adobe InCopy and it does not open it like this. UPDATE: Alternative Solution: Saving it with the XmlTextWriter works too: XmlTextWriter writer = new XmlTextWriter(inCopyFilename, null); doc.Save(writer);
