  • Mysql PHP generated table: doesn't work with Tablesorter

    - by echedey lorenzo
    Hi, I found this great Tablesorter plugin for jQuery but I can't make it work with my PHP generated table. Here's the code: <script type="text/javascript"> function table() { $("#container").load("table.php?randval="+Math.random()); } $(document).ready(function() { table(); $("table").tablesorter(); }); </script> Where #container is the div where the table will be and table is the name of the table. I get the table loaded but sorting function is not working. It works if I put the table directly in html in the page.. but I don't see the point in having a static table for sorting. Any help would be very appreciated.

  • Iphone SDK, arc4random CGPointmake?

    - by Harry
    I have tried using integers to store the number like so: playPin = 35 + arc4random() % 118; playY = -50 - arc4random() %100; if (CGRectIntersectsRect(pin.frame, refreshpin.frame)){ pin.center = CGPointMake(playPin, playY); pinend.center = CGPointMake(pin.center.x, pin.center.y+58); } Then using them, when needed, but... its random the first time, then it just keeps repeating itself. then i tried this: if (CGRectIntersectsRect(pin.frame, refreshpin.frame)){ pin.center = CGPointMake(35 + arc4random() % 118, -50 - arc4random() %100); pinend.center = CGPointMake(pin.center.x, pin.center.y+58); } And this also doesn't work, you cant even see the items i want to display! Any ideas? Thanks. Harry.

  • Canvas context used but not updated on canvas

    - by John Doe
    I am developing an small html5 game, where I have the following code: if(object.blocks){ var blocks = object.blocks, that = this; each(blocks,function(index){ that.blocks.push(new Block(this[index])); }); } I receive an object with some configuration and instantiate blocks with it. It works fine, but the Block class has an method, called draw: this.draw = function (ctx){ if(ctx){ var colors = ['#FF0000','#FFFF00','#0000FF','#00FF00'], color = Math.round(Math.random() * colors.length-1); ctx.fillStyle = colors[color]; ctx.fillRect(this.x,this.y,this.width,this.height); } }; It was working before I moved it into the Block class, but now it draws nothing. This is the code that calls draw: render: function(ctx){ each(this.blocks,function(index){ this[index].draw(ctx); }); } The context comes from the html page, from the main canvas.

  • OpenGL es 2.0 Read depth buffer

    - by Brian
    Hi! As far as i know, we can't read the Z(depth) value in OpenGL ES 2.0. So I am wondering how we can get the 3D world coordinates from a point on the 2D screen? Actually I have some random thoughts might work. Since we can read the RGBA value by using glReadPixels, how about we duplicate the depth buffer and store it in a color buffer(say ColorforDepth). Of course there need to be some nice convention so that we don't lose any information of the depth buffer. And then when we need a point's world coordinates , we attach this ColorforDepth color buffer to the framebuffer and then render it. So when we use glReadPixels to read the depth information at this frame. However, this will lead to 1 frame flash since the colorbuffer is a weird buffer translated from the depth buffer. I am still wondering if there is some standard way to get the depth in OpenGL es 2.0? Thx in advance!:)

  • Redirect output to file

    - by Algorist
    Hi, I have a shell script which is currently running and was running from past 8 hours. It will complete only by tomorrow evening. At the end of the program, it will print 2 million words to standard output. I am running the program on the screen. I forgot to redirect the output to a file. I know I won't be able to copy the data from the window. Is there a way to output the command to a file. I don't want to restart the program. Any thoughts?? Thank you. Bala

  • Reference DLLs not loading in Visual Studio 2010

    - by Adam Haile
    I'm working on a C# 4.0 project in VS2010 and needed to use some older DLLs containing controls that were created in C# 3.5 on VS2008. When I first add the DLLs to the references, I was able to see the namespace via intellisense and create an instance of one of the controls, but when I go to build, it gives me the following error: The type or namespace name 'BCA' could not be found (are you missing a using directive or an assembly reference?) And I do have a using directive for that namespace already, which is now underlined in red, showing that VS cannot find it. And now, intellisense won't pick up that namespace at all. I even tried added the controls to the toolbox (which worked) but then when I drag them to the GUI, it says that it cannot locate the DLL reference, even though it obviously knows where it is. I even tried changing the target framework to 3.5, but still with the same results. Any thoughts as to why this could be happening?

  • How can I tell if a user came to a page via a Google Adwords PPC campaign?

    - by Mike Crittenden
    I have a form with a hidden "Came from Adwords" field that will be marked true (via javascript) if the user came from a PPC campaign and will stay false if not. That way, when the user submits the form, we will have each submission stored with info about whether that submission came from adwords or not, all without the user knowing. How can I fetch this info? I know that Google sets a cookie called Conversion whenever you click a PPC link to a page, but the cookie's content is just random alphanumeric characters. Is there something in the Analytics/Adwords API that will let me test for this? Do I have to resort to adding ?ref=adwords or something onto the PPC URLs so that I can test that way?

  • how to set flex combobox cursor position

    - by crazy horse
    I have a combobox implementation as follows - Based on user input (min 2 chars) in the editable combobox, the data provider is refreshed and drop-down opened, showing different data sets as user input varies. Problem is that after drop-down opens, the cursor moves back to the beginning. So for instance, the user types in "ab", and wants to type in "c" to form the search string "abc". Due to the cursor re-setting its position to 0, the search string instead ends up as "cab". Here's what I tried already (doesn't work) : textInput.mx_internal::getTextField().setSelection(index, index); where index = length of user input. This selects text from index to index (which effectively un-selects text) and is supposed to place the cursor at the end. Any thoughts?

  • Invalid padding on ASP 2.0 cookie, MVC looks ok

    - by brian b
    We have a cookie management library that writes a cookie containing some sensitive information, encrypted with Rijndael. The cookie encrypts and decrypts fine in unit tests (using Moq), works fine for MVC web applications, but when called from an ASP.net 2.0 website, the cookie cannot be decrypted. "Padding is invalid and cannot be removed." We are sure that the cookie value is valid because we tested it 10,000 times with random data in a unit test. There is something about what ASP.NET 2.0 does when it reads and writes the cookie that causes trouble. There has to be a gotcha. Any suggestions?

  • XAML Serialization object not using asp.net shadow copy

    - by mrwayne
    Hi, I'm having a problem where i use the XAML serializer / deserializer for a configuration type file that i have. The problem that i'm getting, is that the XAML serializer is returning objects from the assembly in the /Bin directory, while the rest of the web application is using assembly's stored in the ..../Temporary Files/.. directory. Is there any way to prevent this from happening? Is this a bug in the XAML serializer / assembly loading routines? Every time i compile i need to stop and start the asp.net application so the shadow copy and the bin are exactly the same file. Even when not making a change to the dll and recompiling still causes the problem. Any thoughts on how to get around this problem? Currently i've tried turning shadow copy off, but then i have the same problem of needing to shut down / start up the web app every time i compile. Help!

  • odd problem with jni interacting with dll's - not sure why a change to gc ergonomics fixes it

    - by jim hale
    We were having a problem with our Tomcat jvm blowing up and giving us an hs_* dump at random times but always in the same spot, that wasn't very informative other than saying we had an EXCEPTION_ACCESS_VIOLATION Commenting out various parts of the java that called particular jni functions just made it blow consistently in another spot. By changing our jvm options from: set PAF_OPTS=-Xms1024m -Xmx32000m -server -XX:+UseParallelGC -XX:+UseParallelOldGC -XX:+DisableExplicitGC -XX:+UseCompressedOops -Djava.library.path="%CATALINA_HOME%"\jni -Dcom.sun.management.jmxremote TO set PAF_OPTS=-Xms1024m -Xmx32000m -server -XX:+DisableExplicitGC -XX:+UseCompressedOops -Djava.library.path="%CATALINA_HOME%"\jni -Dcom.sun.management.jmxremote The problem went away. The solution does not give me a warm and fuzzy however and am wondering anyone might understand what's going on under the covers here. Environment: jdk1.6, 64 bit OS and Java, Tomcat, Windows

  • How to Get JSF 2.0 Working with Eclipse 3.5 and JBoss 5.1

    - by Tom Tresansky
    I am running Eclipse 3.5 and JBoss 5.1. I want to create a JSF 2.0 project. I heard here that the Eclipse JBoss Tools plugin version 3.1 (available here) could do this for me. I have installed the plugin. However, if I go to the Project Facets properties page for a Dynamic Web Project, I only see Facets for JavaServer Faces 1.1 and 1.2. My Java facet is set at 6.0, and my Dynamic Web Module to 2.5. In the Targeted Runtimes properties page, I see that I am targeting the JBoss 5.1 Runtime. I understand that Eclipse Helios will be here next week, but I'm curious if its possible to get JSF 2.0 working with 3.5. Any thoughts?

  • How do I show a user's credit based on their session

    - by Jamie
    Hi all - I'm developing a simple LAMP app where users can credit their account using Paypal. I suspect this is a simple issue, but have spent quite a while experimenting to no avail and would appreciate any thoughts: System has a user management system working fine using sessions, but I can't get it to display the current user's credit. But I've been trying things along the lines of: $result = mysql_query(" SELECT * FROM users INNER JOIN account ON account.UserID=account.UserID ORDER BY account.accountID"); while($_SESSION['Username'] = $row['Username'] ) { echo $row['Username']; echo $row['Credit']; } I suspect the while statement is invalid, but I want it to echo username and credit where the current session username = the username stored in the database. Thanks so much for taking a look - very much appreciated.

  • backslashbox is too wide

    - by Tim
    Hi I feel the first column in my longtable is too wide. Please see the figure below My code is: \begin{center} \begin{longtable}{|c|c|c|c|c|c|} \caption{Error rates for SVM and 100 random counts. \label{tab:svmcount100errortable}}\\ \hline \backslashbox{Concepts}{Train sizes} & 10 & 100 & 1000 & 10000 & 100000\\ \hline 1 & 0.49 (0.00) & 0.49 (0.00) & 0.47 (0.00) & 0.43 (0.00) & 0.33 (0.00)\\ \hline \end{longtable} \end{center} I wonder if there is some way to reduce the width of the first column? Thanks and regards!

  • Uploadify works for Visual Studio but not for IIS 7(same machines), using Forms authentication. Doe

    - by Marc
    I'm using the Uploadify jQuery control for client-side uploads. I think my IIS 7 configuration has issues with it. The uploadify POST immediately returns a HTTP 1.1 302 Found, back to my login page. I've tried to allow anonymous access to the uploading section(subfolder) plus the page(script) that processes the image in the web.config, using the location node(configuration ... location). Seems like the Uploadify post is immediately blocked. Again, this worked fine just using Visual Studio 2008, but when I run the site on the same machine I get the redirect. Your thoughts/ideas are very welcomed!

  • Combinatorics, probability, dice

    - by TarGz
    A friend of mine asked: if I have two dice and I throw both of them, what is the most frequent sum (of the two dice' numbers)? I wrote a small script: from random import randrange d = dict((i, 0) for i in range(2, 13)) for i in xrange(100000): d[randrange(1, 7) + randrange(1, 7)] += 1 print d Which prints: 2: 2770, 3: 5547, 4: 8379, 5: 10972, 6: 13911, 7: 16610, 8: 14010, 9: 11138, 10: 8372, 11: 5545, 12: 2746 The question I have, why is 11 more frequent than 12? In both cases there is only one way (or two, if you count reverse too) how to get such sum (5 + 6, 6 + 6), so I expected the same probability..?

  • How to dispose NHibernate ISession in an ASP.NET MVC App

    - by Joe Young
    I have NHibernate hooked up in my asp.net mvc app. Everything works fine, if I DON'T dispose the ISession. I have read however that you should dispose, but when I do, I get random "Session is closed" exceptions. I am injecting the ISession into my other objects with Windsor. Here is my current NHModule: public class NHibernateHttpModule : IHttpModule { public void Init(HttpApplication context) { context.BeginRequest += context_BeginRequest; context.EndRequest += context_EndRequest; } static void context_EndRequest(object sender, EventArgs e) { CurrentSessionContext.Unbind(MvcApplication.SessionFactory); } static void context_BeginRequest(object sender, EventArgs e) { CurrentSessionContext.Bind(MvcApplication.SessionFactory.OpenSession()); } public void Dispose() { // do nothing } } Registering the ISession: container .Register(Component.For<ISession>() .UsingFactoryMethod(() => MvcApplication.SessionFactory.GetCurrentSession()).LifeStyle.Transient); The error happens when I tack the Dispose on the unbind in the module. Since I keep getting the session is closed error I assume this is not the correct way to do this, so what is the correct way? Thanks, Joe

  • JDBC resultset close

    - by KM
    I am doing profiling of my Java application and found some interesting statistics for a jdbc PreparedStatement call: Given below is the environment details: Database: Sybase SQL Anywhere 10.0.1 Driver: com.sybase.jdbc3.jdbc.SybDriver connection pool: c3p0 JRE: 1.6.0_05 The code in question is given below: try { ps = conn.prepareStatement(sql); ps.setDouble(...); rs = ps.executeQuery(); ...... return xyz; } finally { try { if (rs != null) rs.close(); if (ps != null) ps.close(); } catch (SQLException sqlEx) { } } From JProfiler stats, I find that this particular resultspace.close() statement alone takes a large amount of time. It varies from 25 ms to 320s while for other code blocks which are of identical in nature, i find that this takes close to 20 microseconds. Just to be sure, I ran this performance test multiple times and confirmed this data. I am puzzled by this behaviour - Thoughts?

  • Ajax cache control

    - by Brian
    Hello, I am having a problem with ajax requests in Internet Explorer and in Chrome - I cannot bust the cache. Normal pages don't have the problem - it's just the ajax requests. I know that one workaround is to append a random query string variable to the end of the URL. However, I don't want to lose all the benefits of caching, I just want the browser to pick up the new file if the version on the server is different from the cached version. I have tried manually setting the ajax POST header, to no avail: xmlHttp.setRequestHeader("Cache-Control", "must-revalidate"); Adding this to my .htaccess file doesn't work either: <FilesMatch "\.(js|css).*" Header set Cache-Control: "max-age=172800, public, must-revalidate" </FilesMatch Any help would be greatly appreciated. Thanks, Brian

  • PHP: upload files to network shared folder

    - by Xi
    Hi there: I have a problem uploading file to a network shared folder. I can connect to the folder by using windows authentication in IE. The script is as followed: $target_path = '\\\\server\\images\\'; $target_path = $target_path . basename( $_FILES['uploadedfile']['name']); if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) { echo "The file ". basename( $_FILES['uploadedfile']['name']). " has been uploaded"; } else{ echo "There was an error uploading the file, please try again!"; } when i ran it , I got an error message read: Warning: move_uploaded_file(\server\images\pic_firefox.jpg) [function.move-uploaded-file]: failed to open stream: Permission denied in C:\xxxxxxxxx\uploader.php on line 6 I thought that's because windows authentication doesn't work this way. Is there a way I can upload the file by using username/password? Any thoughts would be appreciated.

  • linq2sql - where to enlist transaction (repository or bll)?

    - by Caroline Showden
    My app uses a business layer which calls a repository which uses linq to sql. I have an Item class that has an enum type property and an ItemDetail property. I need to implement a delete method that: (1) always delete the Item (2) if the item.type is XYZ and the ItemDetail is not null, delete the ItemDetail as well. My question is where should this logic be housed? If I have it in my business logic which I would prefer, this involves two separate repository calls, each of which uses a separate datacontext. I would have to wrap both calls is a System.Transaction which (in sql 2005) get promoted to a distributed transaction which is not ideal. I can move it all to a single repository call and the transaction will be handled implicitly by the datacontext but feel that this is really business logic so does not belong in the repository. Thoughts? Carrie

  • IIS7 Custom Errror Handling Troubles for Classic ASP Website

    - by Eaphis
    I recently upgraded a web server from IIS6 to IIS7 for a classic asp application and now experience a bizarre error. In the IIS6 set up there was a custom 500-100 page that functioned properly by capturing errors and delivering an email with error code, error source and error type values. That same structure was set up on the IIS7 machine but now the error emails contain no error information at all. They all come through values such as 'NO SPECIFIC ERROR CODE', 'NO SPECIFIC ERROR DESCRIPTION', 'NO SPECIFIC ERROR SOURCE'. Any one have some thoughts on why my custom error page cannot capture the error information?

  • How to load View from NIB into another NIB?

    - by Sheehan Alam
    I have two NIB's ParentViewController.xib ChildViewController.xib ParentViewController.xib contains a UIView and a UIViewController. ChildViewController.xib contains a UIButton I want ChildViewController.xib to load in the ParentViewController.xib's UIView I have done the following: Created @property for UIView in ParentViewController Connected File's Owner to UIView in ParentViewController Set UIViewController in ParentViewController's NIB Name property to ChildViewController in Interface Builder Set ChildViewController view property to UIView in ParentViewController I was hoping this would load ChildViewController into my UIView in ParentViewController but no luck. I did get the following warning, which could be the culprit: 'View Controller (Child View)' has both its 'NIB Name' property set and its 'view' outlet connected. This configuration is not supported. I also have added additional code in ParentViewController's viewDidLoad(): - (void)viewDidLoad { [super viewDidLoad]; ChildViewController *childViewController = [[ChildViewController alloc]initWithNibName:@"ChildViewController" bundle:nil]; childViewController.view = self.myView; } Any thoughts on why ChildViewController does not load in the UIView of ParentViewController?

  • How to preselect nodes using jsTree jQuery plug-in

    - by Ed Schembor
    I am using the jsTree jQuery plug-in with its "Checkbox" plug-in and using an async http request to lazy-load each level of the tree. All works great, except that I cannot get the tree to pre-select certain nodes after the first level. I am using the "selected" attribute to provide an array of ID's to preselect. ID's in the top level of the tree are correctly pre-selected. However, ID's in lower levels of the tree are not selected when the level loads. Am I missing something? Here is the constructor code: $(sDivID).tree( { data : { async : true, opts : {url : sURL} }, plugins:{ "checkbox" : {three_state : false} }, selected : myArrayOfIDs, ui:{ theme_name : "checkbox", dots : false, animation : 400 }, callback : { beforedata : function(NODE, TREE_OBJ) { return { id : $(NODE).attr("id") || 0, rand : Math.random().toString() } } } } )

  • audioPlayerDidFinishPlaying not being called during scrolling UITableView

    - by Rob
    One of my views is a UITableView which acts as the delegate for an AVAudioPlayer and this table essentially plays sounds when you select a certain row with options to repeat the sound after its finished playing. However, I noticed that if I select a cell with repeat ON for a certain sound and then scroll through the UITableView to select a different sound, it will not call audioPlayerDidFinishPlaying (and therefore not repeat) until after scrolling has stopped. As soon as I stop scrolling, it repeats just fine. Or if I don't scroll at all, it repeats just fine. What could be happening during scrolling that the UITableView is no longer acting as the delegate and calling audioPlayerDidFinishPlaying? Any thoughts?
