  • jquery $.ajax to php problem

    - by Pouya
    hi.i have two problems with jquery $.ajax. first problem is ihave a php file named action.php and here the code: if($_GET['action']=='add'){ //rest of the code here } And i use jquery $.Ajax function to call that when form fills: $.ajax({type:"POST", url:"action.php?action=add", data:$("#form").serialize(), cache:false, timeout:10000}); this works but i wanted to know is there anyway to send the action=add code with data and not the url? and the second problem that i have is that i have a link: <a href="#" onclick="delete(4);">delete row from mysql where id is 4</a> and a jquery function: function deleteUser(id){ $.ajax({type:"POST", url:"action.php?action=delete", data:"id="+id, cache:false, timeout:10000});} and of course the action.php code: if($_GET['action']=='deletestudent'){ mysql_query("DELETE FROM `students` WHERE `student_id` = {$_POST['id']}"); } but it doesn't work.what should i do?

  • Performance benefits of upgrading Richfaces to newer version

    - by peteDog
    I have a client that's running an application based on JBoss 4.0.5, Seam 1.2 and RichFaces 3.0.1. Their system is having performance problems due to the fact that a lot of data is coming back from the server to be displayed on screen and it seems like the rendering of that data is taking forever. The data brought back is displayed in a tabbed interface, but the tabs aren't currently being loaded individually, but all at once. I'm trying to build up a case to present to the client on the benefits of upgrading to never version of RichFaces, which, as I understand it, has added a great number of features related to tabbed panels and being able to use ajax to page the data and load the chunks you actually need to display at the moment, and not the rest that's in other tabs. The move to a newer version of RichFaces will also result in never versions of Jboss and Seam, as the current production build of RichFaces 3.2.1 requires JSF 1.2. IF anyone has some suggestions or experience on performance of current versions RichFaces, paging, etc, I would really appreciate some feedback.

  • LinkedList cannot be serialised?

    - by iTayb
    Here are my classes: http://pastebin.com/3dc5Vb1t When I try to run BookStore b = new BookStore(); b.LoadFromXML(Server.MapPath("list.xml")); Label1.Text = b.ToString(); I get the following error: You must implement a default accessor on System.Collections.Generic.LinkedList`1[[Book, App_Code.cxsacizw, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null]] because it inherits from ICollection. The error source is XmlSerializer s = new XmlSerializer(typeof(BookStore)); When I tried to look for a solution on google, I found it that LinkedList has some problems with serialization. How can I deal with it? Thank you very much.

  • WIX: COM unregistration when removing one of two programs

    - by madbadger
    Hello, I am relatively new to WiX. It is a great tool, but I still need some time to learn it better. I have encountered a problem with registration and unregistration of a COM component. I have created installers for two applications, lets call them A and B. Both are using the same COM component. I have used the heat tool, as recommended. When installing A or B, the component is registered without any problems. But when I install A and B, then remove A (with Add/Remove programs) the COM class gets unregistered and B cannot use it anymore. Is there a clean solution to prevent this from happening? I would like to unregister the COM when BOTH A and B are uninstalled. Any help would be appreciated, Best regards, madbadger

  • Normalize FFT magnitude to imitate WMP

    - by Bevin
    So, I've been working on a little visualizer for sound files, just for fun. I basically wanted to imitate the "Scope" and "Ocean Mist" visualizers in Windows Media Player. Scope was easy enough, but I'm having problems with Ocean Mist. I'm pretty sure that it is some kind of frequency spectrum, but when I do an FFT on my waveform data, I'm not getting the data that corresponds to what Ocean Mist displays. The spectrum actually looks correct, so I knew there was nothing wrong with the FFT. I'm assuming that the visualizer runs the spectrum through some kind of filter, but I have no idea what it might be. Any ideas?

  • Sudoku solver evaluation function

    - by Rich
    Hi, So I'm trying to write a simple genetic algorithm for solving a sudoku (not the most efficient way, I know, but it's just to practice evolutionary algorithms). I'm having some problems coming up with an efficient evaluation function to test if the puzzle is solved or not and how many errors there are. My first instinct would be to check if each row and column of the matrix (doing it in octave, which is similar to matlab) have unique elements by ordering them, checking for duplicates and then putting them back the way they were, which seems long winded. Any thoughts? Sorry if this has been asked before...

  • ASP.Net Count Download Clicks

    - by Marco
    Hello, I thought that this was easier… I have a asp:hyperlink control, with target=”_blank”, pointing to the file I want the user to download. My plan is to track the number of times, the users click on this link. I thought in placing it in ajax update panel, to catch the postback and avoid full page refresh. However, hyperlink doesn’t have a onClick method. On the other hand I could use a linkbutton, which has a onClick built in. But It’s harder to make the file open in a new window… and I would also have to do something like: Response.AppendHeader("Content-Disposition","attachment; filename=myImage.jpg"); But I heard that the above approach has some problems with PPT, PPTX, PPS, PPSX… What is you'r opinion on this? How and why, would you do it?

  • Storyboard elements are not sized properly on the device

    - by Joel Fischer
    In the storyboard, I am placing a table view element into a subclassed UIView. The element is not appearing on the iPad device I am running it on the same as it appears in the storyboard however. This also happens for additional content that I place into the storyboard. Below is a screenshot as it appears in the storyboard, as well as UI width/height information. And here is the description of the UI file running on the iPad. https://gist.github.com/4323186 (embedding it directly into the post is giving me problems) You'll notice that the tableview is explicitly set at 178 width, and is showing up in the description as 276 width. My initial thought was that perhaps a cell was forcing the parent to be larger (I'm very new to iOS UI development), but drilling into that shows the prototype cell it appears that the width is defined by it's parent at 178. The image views and label also are appearing in the incorrect spot, as shown in the second image below.

  • Why is there an implicit conversion from Float/Double to BigDecimal, but not from String?

    - by soc
    Although the situation of conversion from Doubles to BigDecimals has improved a bit compared to Java scala> new java.math.BigDecimal(0.2) res0: java.math.BigDecimal = 0.20000000000000001110223024625156... scala> BigDecimal(0.2) res1: scala.math.BigDecimal = 0.2 and things like val numbers: List[BigDecimal] = List(1.2, 3.2, 0.7, 0.8, 1.1) work really well, wouldn't it be reasonable to have an implicit conversion like implicit def String2BigDecimal(s: String) = BigDecimal(s) available by default which can convert Strings to BigDecimals like this? val numbers: List[BigDecimal] = List("1.2", "3.2", "0.7", "0.8", "1.1") Or am I missing something and Scala resolved all "problems" of Java with using the BigDecimal constructor with a floating point value instead of a String, and BigDecimal(String) is basically not needed anymore in Scala?

  • CSS for https urls

    - by Vincent
    Hello, looking for some help with images referenced within the stylesheet. I have no problems with these from non secure locations within the site but only from https. The stylesheet loads fine and displays everything correctly except for the images. example: body { margin: 0; padding: 0; background: url(/img/background_tile.gif) top left repeat-x; text-align: center; background-color: #fff; } All my css files and other image paths inside the code use relative urls to images. How can I make sure they all work fine without hard coding my image paths with https or http? I want the code to work fine with http and https. Thanks

  • Algorithm to determine thread "hotness"

    - by nickf
    I'm trying to come up with a way to determine how "hot" certain threads are in a forum. What criteria would you use and why? How would these come together to give a hotness score? The criteria I'm thinking of include: how many replies how long since the last reply average time between replies The problems this algorithm must solve: A thread which has 500 replies is clearly hot, unless the last reply was over a year ago. A thread with 500 replies that was replied to a second ago is clearly hot, unless it's taken 4 years to reach 500 replies. A thread with 15 replies in the last 4 minutes is really hot! Any ideas, thoughts or complete solutions out there?

  • Pagination For SMS in Android specifically

    - by Priyank
    Hi. I had a pagination related question posted earlier. Here I went through the posted answers and suggested choices and I realized that to implement pagination in an application I could still write db level queries and ensure that I could implement pagination, even if in a crude form. However I have few follow up questions now: I am trying to show SMS from a content provider. Suppose I don't want to use content provider; can I access SMS table in database through my application. Aoes android's security framework allow that? How do people generally handle pagination problems in android, related to content that they are not storing but instead are fetching through content providers. (Android's own or custom) Isn't this a bigger problem. I am surprised to find so little text online about it.

  • Leak - GeneralBlock-3584

    - by lamicka
    When i try to check leaks of my iPhone App using Instruments, everything is just fine. Same App on actual real device shows this leak for a few times during the app launch. It is pretty non-deterministic and it happens in system libraries. I tried to google down the solution without a luck. Anyone experiencing the same problems? Anyone knows the solution? I find interesting, that every of my leak in code will crash the app sooner or later. These GeneralBlock-3584 leaks keeps app perfectly stable. Might this be reason for AppStore rejection? Thanx for any answer regarding this undocumented problem (Apple is silent unfortunately).

  • How to get all rows but specifc columns from a DataTable?

    - by Oliver
    Currently i am having some problems with getting some data out of a DataTable by selecting all rows, but only some columns. To be a little more descriptive here is a little example: Sample Data | ID | FirstName | LastName | Age | +----+-----------+----------+-----+ | 1 | Alice | Wannabe | 22 | | 2 | Bob | Consumer | 27 | | 3 | Carol | Detector | 25 | What i have So what we got from our GUI is a IEnumerable<DataColumn> selectedColumns and there we'll find two elements (FirstName and LastName). Now i need some result which contains all rows, but only the above two columns (or any other list of selected columns). So far i already used LINQ on several one dimensional objects, but this two dimensional object gives me a little headache. // The hard-coded way Table.AsEnumerable().Select(row => new { FirstName = row[1], LastName = row[2] }); // The flexible way Table.AsEnumerable().Select(row => row ???) But how can i now say, which columns from row should be selected by using my selectedColumns?

  • Creating a spider using Scrapy, Spider generation error.

    - by Nacari
    I just downloaded Scrapy (web crawler) on Windows 32 and have just created a new project folder using the "scrapy-ctl.py startproject dmoz" command in dos. I then proceeded to created the first spider using the command: scrapy-ctl.py genspider myspider myspdier-domain.com but it did not work and returns the error: Error running: scrapy-ctl.py genspider, Cannot find project settings module in python path: scrapy_settings. I know I have the path set right (to python26/scripts), but I am having difficulty figuring out what the problem is. I am new to both scrapy and python so there is a good possibility that I have failled to do something important. Also, I have been using eclipse with the Pydev plugin to edit the code if that might cause some problems.

  • 100% height on nested table cell in IE

    - by James Cooper
    I want a nested table to expand to the height of the enclosing cell. This works as expected in Firefox/Chrome/Safari, but not in IE7 or IE8. Please see the example here: http://www.bitmechanic.com/heightDemo.html The DOCTYPE is relevant. While the demo above validates as HTML 4.01 Strict, it does not render properly in IE7. If I remove the DOCTYPE entirely, or set it to HTML 3.2, it renders properly in IE. Any suggestions on how to get this to render in 4.01 (strict or loose)? The actual web site is a bit more complicated -- changing the DOCTYPE will cause all sorts of other problems. We're struggling to understand the (presumed) IE bug here and how to work around it. thanks -- James

  • ASP.NET CompositeControl with child controls that contain children

    - by tomfanning
    I am building an ASP.NET server control which extends CompositeControl. I need fine grained control over the rendering, so I override Render() and output the child controls myself, interspersed with HTML generation code: writer.AddStyleAttribute("float", "left"); writer.RenderBeginTag(System.Web.UI.HtmlTextWriterTag.Div); writer.RenderBeginTag(System.Web.UI.HtmlTextWriterTag.Strong); writer.Write("Table"); writer.RenderEndTag(); // strong writer.WriteBreak(); tableList.RenderControl(writer); writer.RenderEndTag(); // div This works really well for user controls that just contain simple controls without children of their own. However, if I want to use something like a MultiView or an UpdatePanel I run into problems, since I can't override Render() on View or UpdatePanel without extending them, and if I do extend them the implementation would presumably have to depend on FindControl() voodoo to get references to the right controls during render. That doesn't sound like the right way to do this - is there a better way?

  • Using mergedModelFromBundles: and versioning (CoreData)

    - by charlax
    Hi everybody, I'm trying to use the migration feature in CoreData. I've followed the Apple Documentation. I have a problem in the following method: /** Returns the managed object model for the application. If the model doesn't already exist, it is created by merging all of the models found in the application bundle. */ - (NSManagedObjectModel *)managedObjectModel { if (managedObjectModel != nil) { return managedObjectModel; } /* * NSInvalidArgumentException', reason: '*** -[NSCFArray insertObject:atIndex:]: attempt to insert nil' * 2010-02-17 16:27:15.338 Patrimoine[3037:207] */ managedObjectModel = [[NSManagedObjectModel mergedModelFromBundles:nil] retain]; return managedObjectModel; } It appears that there is the same problem on http://iphonedevelopment.blogspot.com/2009/09/core-data-migration-problems.html Yet I did choose the method Apple suggests, by using the menu option "Add Model Version". Do you have any idea?

  • How to debug unreleased COM references from managed code?

    - by Marek
    I have been searching for a tool to debug unreleased COM references, that usually cause e.g. Word/Outlook processes to hang in memory in case the code does not call Marshal.ReleaseCOMObject on all COM instances correctly. (Outlook 2007 partially fixes this for outlook addins, but this is a generic question). Is there a tool that would display at least a list of COM references (by type) held by managed code? Ideally, it would also display memory profiler-style object trees helping to debug where the reference increment occured. Debugging at runtime is not that important as being able to attach to a hung process - because the problem typically occurs when the code is done with the COM interface and someone forgot to release something - the application (e.g. winword) hangs in memory even after the calling managed application quits. If such tool does not exist, what is the (technical?) reason? It would be very useful for debugging a lot of otherwise very hard to find problems when working with COM interop.

  • When will NAnt reach version 1.0

    - by sundar venugopal
    I like Nant very much. I do a lot of scripting with NAnt. It is a great little tool. Since NAnt is pre 1.0, when problems occur, I often think if that it is a problem with NAnt itself, but this is not always the case. One funny example: After running the oracle scripts I parsed the log output to make sure there was no problem. I was testing this with a small log file and it was fine. I used the task to load the file contents to a string property and used a regex to search for errors. When I used this script for a large log file, I stopped getting the "build failed" message at the bottom, because I was printing the error messages. Because the "build failed" was hiding at the top, I thought NAnt crashed, but it worked fine. It would be better for NAnt to have a 1.0 release. Any reasons why not?

  • Porting iPhone app to iPad fails to sign?

    - by mobibob
    I am able to create a new application profile targeted for my iPad, however, when I convert from iPhone to "Universal" device, I am getting an error in signing. [BEROR]Code Sign error: a valid provisioning profile matching the application's Identifier 'rfc1034identifier' could not be found Also note: I am able to run it in the simulator (which does not require signing). It is a very old application ~OS version 2.x or 3.1 that had SDK problems which required more manual process to get the signing code into the build settings, so I would not be surprised if there is some residual foo in the build settings.

  • How to correctly formalize the command line usage of GNU/Linux commands?

    - by Francesco Turco
    I'd like to write down a BNF-like formal grammar for describing the command line usage of some GNU/Linux tools. For example I can describe the usage of the cat command as: (cat-command) : 'cat' (arguments-list) (arguments-list) : (argument) (arguments-list) : (arguments-list) (argument) (argument) : (file) The problem is I can't write down a precise grammar for some commands such as md5sum. My first attempt at that would be the following: (md5sum-command) : 'md5sum' (arguments-list) (arguments-list) : (argument) (arguments-list) : (arguments-list) (argument) (argument) : (file) (argument) : '--check' But as you can see this grammar allows you to specify the --check argument as many times as you wish, which is incorrect as you should use it at most one time. How can I fix that? Also, what kind of formal grammars I should study for better treating this kind of problems? Thanks.

  • PHP: Alternative to SESSIONS

    - by iamjonesy
    Hi, I have a PHP application that relies on session variables quite a lot. After login the user get redirected to a page that executes code to set up a load of session variables depending on who the user is. The application is using data from different sources and the sessions are used to store ID numbers to query the databases. So when the user goes to a page that will query their asset management system their ID for that particular database is called via the session. I've had a LOT of problems with session variables recently. Sometimes only one session file is created during the lifetime of the app, and sometimes each session request results in a new session id (still haven't managed to find out why!). My question is this. Is there an alternative to using session variables for this? Like globals or some other way? Any help most appreciated! Regards, Jonesy
