  • how to pass value to controller??

    - by rajesh
    When I try to pass url value to controller action, action is not getting the required value. I'm sending the value like this: function value(url,id) { alert(url); document.getElementById('rating').innerHTML=id; var params = 'artist='+id; alert(params); // var newurl='http://localhost/songs_full/public/eslresult/ratesong/userid/1/id/27'; var myAjax = new Ajax.Request(newurl,{method: 'post',parameters:params,onComplete: loadResponse}); //var myAjax = new Ajax.Request(url,{method:'POST',parameters:params,onComplete: load}); //alert(myAjax); } function load(http) { alert('success'); } and in the controller I have: public function ratesongAction() { $user=$_POST['rating']; echo $user; $post= $this->getRequest()->getPost(); //echo $post; $ratesongid= $this->_getParam('id'); } But still not getting the result. I am using zend framework.

  • jQuery/Ajax IE7 - Long requests fail

    - by iQ
    Hi guys, I have a problem with IE7 regarding an ajax call that is made by jQuery.load function. Basically the request works in cases where the URL string is not too long, but as soon as the URL gets very large it fails. Doing some debugging on the Ajax call I found this error: URL: <blanked out security reasons but it's very long> Content Type: Headers size (bytes): 0 Data size (bytes): 0 Total size (bytes): 0 Transferred data size (bytes): 0 Cached data: No Error result: 0x800c0005 Error constant: INET_E_RESOURCE_NOT_FOUND Error description: The server or proxy was not found Extended error result: 0x7a Extended error description: The data area passed to a system call is too small. As you can see, it looks like nothing is being sent. Now this only happens on IE7 but not other browsers, with IE8 there is a small delay but still works. The same request works fine when the URL string is relatively small. Now I need this working on IE7 for compatibility reasons and I cannot find workarounds for this so any help is greatly appreciated. The actual ajax call is like this: $("ID").load("url?lotsofparams",callbac func(){}); "lotsofparams" can vary, sometimes being small or very large. It's when the string is very large that I get the above error for IE7 only.

  • S3 browser upload via POST: unable to handle errors gracefully

    - by samf
    I am writing an app where I want the customer to be able to upload to Amazon S3 straight from the browser. I can make this work just fine. But when errors occur, I want to handle them more gracefully than splattering an XML document on the customer's screen. I have a scheme that I think would work, but it's failing. Here's what I'm trying: Create a form to do the upload, and store the form on S3 itself, in the same domain as the "action" attribute of the form. Redirect the customer to this form. Now their browser is sitting on https://<bucket>.s3.amazonaws.com/something. The page contains a hidden iframe. The form sets its target to the iframe. The load event handler looks at the contents of the iframe, and acts upon it. So, something like this: <iframe id="foo" name="foo" style="display: none" /> <form target="foo" action="https://<bucket>.s3.amazonaws.com/"> <input type="hidden" name="..." value="..." /> <input type="file" name="file" /> </form> with this javascript (using jquery): function handler() { var message = $("#foo").contents().find('message').text(); alert(message); } $("#foo").load(handler); Using firebug, I can see that the iframe contains an XML document, that contains a "message" node. However, the .find('message') always fails to find anything within the XML document. Notice that the action of the form has the same domain, port, and scheme as the document itself. So, I don't think that I should be running afoul of the same-origin policy. Right? But it fails every time. This is using Firefox and Google Chrome browsers. Thanks for any advice!

  • How can I know when SQL Full Text Index Population is finished?

    - by GarethOwen
    We are writing unit tests for our ASP.NET application that run against a test SQL Server database. That is, the ClassInitialize method creates a new database with test data, and the ClassCleanup deletes the database. We do this by running .bat scripts from code. The classes under test are given a connection string that connects to the unit test database rather than a production database. Our problem is, that the database contains a full text index, which needs to be fully populated with the test data in order for our tests to run as expected. As far as I can tell, the fulltext index is always populated in the background. I would like to be able to either: Create the full text index, fully populated, with a synchronous (transact-SQL?) statement, or Find out when the fulltext population is finished, is there a callback option, or can I ask repeatedly? My current solution is to force a delay at the end the class initialize method - 5 seconds seems to work - because I can't find anything in the documentation.

  • Flex: Scale an Image so that its width matches contentWidth?

    - by Tong Wang
    I have a dynamic layout, where an image is loaded into an HBox: <mx:HBox ...> <mx:Image height="100%" .../> </mx:HBox> only the image's height is set on the image, so that it can take all the vertical space available, while its width is left undefined and I expect the width to scale accordingly with its height. It turns out that the image's height is equal to its contentHeight, i.e. height scales properly; however, the image's width is still the same as measuredWidth (the image's original width), and is not scaled accordingly. For example, if the image's original size is 800x600 and if the HBox is 300 in height, then image height will scale down to 300, however its width doesn't scale down to 400, instead it stays at 800. I tried to add an event listener to explicitly set the image width: <mx:Image id="img" height="100%" updateComplete="img.width=img.contentWidth;" .../> It works only the first time the image is loaded, after that, if I use Image.load() to dynamically load different images, it stops working - the image width is set to 0. Any help/advice will be highly appreciated.

  • Custom API requirement

    - by Jonathan.Peppers
    We are currently working on an API for an existing system. It basically wraps some web-requests as an easy-to-use library that 3rd party companies should be able to use with our product. As part of the API, there is an event mechanism where the server can call back to the client via a constantly-running socket connection. To minimize load on the server, we want to only have one connection per computer. Currently there is a socket open per process, and that could eventually cause load problems if you had multiple applications using the API. So my question is: if we want to deploy our API as a single standalone assembly, what is the best way to fix our problem? A couple options we thought of: Write an out of process COM object (don't know if that works in .Net) Include a second exe file that would be required for events, it would have to single-instance itself, and open a named pipe or something to communicate through multiple processes Extract this exe file from an embedded resource and execute it None of those really seem ideal. Any better ideas?

  • Java Web Server with Jetty - TCP Connections Taking Long

    - by daysleeper
    I have an application with fairly high traffic (20K req/min) running on the JVM with a Jetty servlet container on Ubuntu. Below is my Jetty configuration: 10 20 2000 2 When I analyze the network traffic, I realize that sometimes it is taking long to establish TCP connections on the port that Jetty is running. The long connections are varying between 3.0s and 9.0s. The port is configured to accept MAX number of TCP connections. Do you know what might be causing the delay in accepting connections? Thanks

  • Check if a GtkEntryCompletion is currently visible

    - by Joe
    I have a GtkEntry with a GtkEntryCompletion attached to it. The Entry does something fairly expensive if the user hasn't changed the text in it for a second (to preview search results). However it's very common for the user to stop typing in order to select the correct autocompletion. So I'd like to delay the preview until the user has stopped typing and the GtkEntryCompletion is not currently suggesting anything. GtkEntryCompletion is not a real widget however, and doesn't seem to have any way to get to whatever widget does own the CellRenderers it uses. Is there a way I can detect if it's visible or not?

  • C/C++ detect network type

    - by Gavimoss
    I need to write a win32 c/c++ application which will be able to determine whether the PC it's running on is connected to one of 2 networks. The first network is the company LAN (which has no internet connection) and the second network is a standalone switch with a single PC connected to it (the PC that the program is running on). I'm pretty new to network programming but so far I have tried testing to see if a network drive which is held on our LAN can be mapped. This works fine if the PC is connected to the LAN, the drive mapping succeeds so so LAN detection is successful. However, if the PC is connected to the switch, this results in a VERY long timeout which is not a suitable as it will delay the program so much as to make it unusable. Does anyone have any alternative suggestions? I'm using c/c++ in VS 6.0

  • How to add an object to a html string?

    - by Philippe Maes
    I'm trying to load several images by a drop action and than resizing them and adding them as a thumbnail. The resize part is very important because the images can be very large and I want to make the thumbnails small of size. Here is my code: loadingGif(drop); for (var i=0;i<files.length;i++) { var file = files[i]; var reader = new FileReader(); reader.onload = function(e) { var src = e.target.result; var img = document.createElement('img'); img.src = src; var scale = 100/img.height; img.height = 100; img.width = scale*img.width; output.push('<div id="imagecontainer"><div id="image">'+img+'</div><div id="delimage"><img src="img/del.jpg"" /></div></div>'); if(output.length == files.length) { drop.removeChild(drop.lastChild); drop.innerHTML += output.join(''); output.length = 0; } } reader.readAsDataURL(file); } As you can probably tell I insert a loading gif image in my dropzone until all files are loaded (output.length == files.length). When a file is loaded I add html to an array which I will print if the load is complete. The problem is I can't seem to add the img object (I need this object to resize the image) to the html string, which seems obvious as the img is an object... So my question to you guys is: how do I do this? :)

  • Isotope.js help: Changing item image after sorting

    - by user3643081
    This is a general question on how to go about building a project I have in mind, and the best way to set off on the right foot. I am fairly new to JS, please be gentle. I want to use isotope.js (or a similar script) to display a page with multiple items (about 30 different plants found in a garden) and the ability to sort them by seasons of the year + "what is most beautiful now" + and "view all" (a total of 6 categories) . On load, or when sorted by either "what is beautiful now" or "view all", I need each item to reflect the image of the current season we are in. When sorted by season, I need those "current" images to switch over to a designated seasonal image of that plant. Therefore, each sortable item will ultimately have 4 different versions with 4 different images in the background ready to surface when plants are sorted. (perhaps 5 if it makes more sense to have a "current" version besides the 4 seasonal versions.) My question: what approach can I take to achieve this effect in a manageable way? Can isotope apply a class to items sorted? Assuming it can: Should each item have 4 inline images, each with a css class, that I then control by using display:inline; and display:none; properties from my stylesheets? (I worry that this approach would significantly increase load times) Would it make more sense to create a blank dummy div who's background I control similarly to the example above -relying mostly on CSS. Or is there some other way involving JS I am overlooking? Any help would be appreciated. Examples of what you suggest would be immensely helpful.

  • how does this animation work?

    - by icicleking
    I'm working with cookies to run or not run a jQuery animation someone else built: $(function () { $('div.transitional').click(function () { $('div.intro').removeClass('hidden'); $('div.final').off('click'); }); ShowDiv($("div.transitional.hidden")[0]); }); function ShowDiv(target) { target = $(target); target.removeClass('hidden'); target.delay(500).animate({ opacity: 1.0 }, 300, 'easeInExpo', function () { ShowDiv($("div.transitional.hidden")[0]); }) } I have the cookie part working, but I'm confused about the anonymous function and the "ShowDiv" function. What is each part doing? Functionally, the animation makes visible a series of pictures, then the whole site. I want to skip the animation and just make the whole site visible(if cookies='visited'). I'd like to do this without rewriting the animation script. here's a link. What happens now is if you have the cookie the animation doesn't run and everything is hidden.

  • When is a Web Service constructor called? [Java Netbeans 6.7.1 & Tomcat 6.0.18]

    - by Shaitan00
    I am migrating a Java RMI application to Java Web Service (school assignment) and I've encountered an issue... Currently my Java Server creates an instance of the Remote Object, this object has a constructor and takes a parameter (int ID) which tells it which database to load in memory - works like a charm ... Now, migrating this to Web Services is causing my a problem - first I needed to add a default constructor because it wouldn't deploy without it, and then while doing some reading all these discussions about "stateless web services" kept coming up ... For example, if I "start" my webservice with parameter(0) it would load from Databse 0 and all requests from Clients would be done using that data... I want this to only happen when I start the WebService and NOT everytime the client connects... Loading from the DB is expensive and takes time, so I want to do it once so that clients when they connect just deal with the data in memory ... This is how it works with my Java RMI .... but can this also work with Web Services? Any advice would be much appreciated. Thanks,

  • Loading a UIView from a UITableview

    - by Michael Robinson
    I can firgure out how to push a UIView from a Tableview and have the "child" details appear. Here is the view I'm trying to load: Here is the code that checks for children and either pushes a itemDetail.xib or an additional UITable, I want to use the above .xib but load the correct contents "tableDataSource" into the UItable: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { //Get the dictionary of the selected data source. NSDictionary *dictionary = [self.tableDataSource objectAtIndex:indexPath.row]; //Get the children of the present item. NSArray *Children = [dictionary objectForKey:@"Children"]; if([Children count] == 0) { ItemDetailViewController *dvController = [[ItemDetailViewController alloc] initWithNibName:@"ItemDetailView" bundle:[NSBundle mainBundle]]; [self.navigationController pushViewController:dvController animated:YES]; [dvController release]; } else { //Prepare to tableview. FirstTab *rvController = [[FirstTab alloc] initWithNibName:@"FirstView" bundle:[NSBundle mainBundle]]; //Increment the Current View rvController.CurrentLevel += 1; //Set the title; rvController.CurrentTitle = [dictionary objectForKey:@"Title"]; //Push the new table view on the stack [self.navigationController pushViewController:rvController animated:YES]; rvController.tableDataSource = Children; [rvController release]; } } Thanks for the help. I see lots of stuff on this but can't find the correct push instructions.

  • c++ simple conditional logging

    - by Sunny
    Disclaimer: I'm not a c++ developer, I can only do basic things. (I understand pointers, just my knowledge is so rusty, I haven't touch c/c++ for about 20 years :) ) The setup: I have an Outlook addin, written in C#/.Net 1.1. It uses a c++ shim to load. Usually, this works pretty well, and I use in my c# code nlog for logging purposes. But sometimes, the addin fails to load, i.t. it does not hit the managed code at all for me to be able to investigate the problem from the log files. So, I need to hook some basic logging into the c++ shim - just writing in a file. I need to make it as simple as possible for our users to enable. Actually I would prefer not to ship it by default. I was thinking about something, which will check if a specific dll is present (the logging dll), and if so, to use it. Otherwise, it will just not log anything. That way, when I have a user with such a problems, I can send him only the logging dll, the user will save it in the runtime directory, and I'll have the file. I guess this have to be done with some form a factory solution, which returns either a dummy logger, or if the dll is found, a real one. Another option would be to make some simple logger, and rebuild the shim with or w/o using it, based on directives. This is not the desirable approach, because the shim needs to be signed, and I have to instruct the user to make a backup copy of the "real" one, then restore when done, etc., instead of just saving and deleting a dll. I'd appreciate any good suggestion how to approach it, together with links or sample code how to go after this. Cheers

  • Can my thread help the OS decide when to context switch it out?

    - by WilliamKF
    I am working on a threaded application on Linux in C++ which attempts to be real time, doing an action on a heartbeat, or as close to it as possible. In practice, I find the OS is swapping out my thread and causing delays of up to a tenth of a second while it is switched out, causing the heartbeat to be irregular. Is there a way my thread can hint to the OS that now is a good time to context switch it out? I could make this call right after doing a heartbeat, and thus minimize the delay due to an ill timed context switch.

  • Slow loading of UITableView. How know why?

    - by mamcx
    I have a UITableView that show a long list of data. Use sections and follow the sugestion of http://stackoverflow.com/questions/695814/how-solve-slow-scrolling-in-uitableview . The flow is load a main UITableView & push a second selecting a row from there. However, with 3000 items take 11 seconds to show. I suspect first from the load of the records from sqlite (I preload the first 200). So I cut it to only 50. However, no matter if I preload only 1 or 500, the time is the same. The view is made from IB and all is opaque. I run out of ideas in how detect the problem. I run the Instruments tool but not know what to look. Also, when the user select a cell from the previous UITable, no visual feedback is show (ie: the cell not turn selected) for a while so he thinks he not select it and try several times. Is related to this problem. What to do? NOTE: The problem is only in the actual device: iPod Touch 2d generation Using fmdb as sqlite api Doing the caching in viewDidLoad Using NSDictionary for the caching Using a NSAutoreleasePool for the caching part. Only caching the row ID & mac 4 fields necesary to show the cell data UIView made with interface builder, SDK 2.2.1 Instruments say I use 2.5 MB in the device

  • Trouble using files Globally

    - by Nightforce2
    Recently I ran into trouble when I discovered that vista restricts what can be installed into the system32 directory even though I am the administrator for this computer. It will not allow me to register dll files so I can use programs like wget globally like how programs "nslookup" etc are used. Keeps giving me this error. Regsvr32: The module "C:\Windows\System32\libeay32.dll" failed to load. make sure the binary is stored at the specified path or debug it to check for problems with the binary or dependent .DLL files. The specified module could not be found. Moving the required DLL files to system32 prompts me to confirm administrator privileges are needed to move these files, So I give the permission, copy the files to system32, and run wget to confirm. This is where it tells me it cannot find the DLL's required to run and when using regsvr32 it says it cannot find the entry point so it will not load the DLL asking me if it is a valid DLL or OCX file. If I leave the DLL's that came with wget in the same folder as wget outsite of system32 they work vice adding them to system32 with the exe it will not work saying it cannot read the those dll files. Is there a way around this or Do I need to Upgrade to Windows 7 to get away from these problems/restrictions?

  • How do I cancel a text selection after the initial mousedown event?

    - by cwillu-gmail
    I'm trying to implement a pop-up menu based on a click-and-hold, positioned so that a (really) slow click will still trigger the default action, and with the delay set so that a text-selection gesture won't usually trigger the menu. What I can't seem to do is cancel the text-selection in a way that doesn't prevent text-selection in the first place: returning false from the event handler (or calling $(this).preventDefault()) prevents the user from selecting at all, and the obvious $().trigger('mouseup') doesn't doesn't do anything with the selection at all. This is in the general context of a page, not particular to a textarea or other text field. e.stopPropogation() doesn't cancel text-selection. I'm not looking to prevent text selections, but rather to veto them after some short period of time, if certain conditions are met.

  • jCarousel jQuery ajax loading 1000 records

    I'm using jCarousel to present a vertical scolling list of +-1000 names. I am using ajax to load the data 100 records at a time then when all the data has loaded I just let the jCarousel loop in the DOM. I have the ajax and loop all working but would like to make the code work no matter how large the total record count becomes. 1) I'd like to eliminate the 1201 fixed number and use a variable. 2) I currently loop on every record I see (carousel.first) to see if it matches my reload position(s) (albeit the loop is ony 12x it still seems a little "loopy") Any suggestions on improving this? function mycarousel_itemLoadCallback(carousel, state) { //if (carousel.has(carousel.first, carousel.last)) { //return; //} var getCount = 100; // Number of records to grab at a time var maxCount = 1201; // total possible number of records var visible = 9; // the number of records you can see in the window so this creates a pre-load by this number of records for (var i = 1; i < maxCount; i+=getCount ) { if (carousel.first === 1 || carousel.first === (i-visible)){ var getFrom = i; var getTo = getFrom+(getCount-1); //alert('TOP Record ='+carousel.first+'\n Now GET '+getFrom+'-'+getTo); jQuery.get('#ajaxscript#', { first: getFrom, last: getTo }, function(xml) { mycarousel_itemAddCallback(carousel, getFrom, getTo, xml); }, 'xml' ); break; } } };

  • Weird Rails database errors

    - by Jason Swett
    I've had some trouble getting my Rails app to connect to PostgreSQL so I decided to just say screw it and use SQLite for now. (I'm using the tutorial here: http://guides.rubyonrails.org/getting_started.html) I started a BRAND NEW, fresh Rails app from this tutorial. When I visit my app in the browser after deleting public/index.html, I get this the first time: Please install the pg adapter: `gem install activerecord-pg-adapter` (no such file to load -- active_record/connection_adapters/pg_adapter) That's odd to me because I'm not mentioning PostgreSQL anywhere. Here's my databases.yml: # SQLite version 3.x # gem install sqlite3-ruby (not necessary on OS X Leopard) development: adapter: sqlite3 database: db/development.sqlite3 pool: 5 timeout: 5000 # Warning: The database defined as "test" will be erased and # re-generated from your development database when you run "rake". # Do not set this db to the same as development or production. test: adapter: sqlite3 database: db/test.sqlite3 pool: 5 timeout: 5000 production: adapter: sqlite3 database: db/production.sqlite3 pool: 5 timeout: 5000 To make things more confusing, I only get that "pg adapter" error on the first load. For every subsequent page request, I get this error: ActiveRecord::ConnectionNotEstablished So even though I removed all mention of PostgreSQL, I'm still getting errors. What could be going on?
