    - by agazerboy
    Hi All, I asked a question before but duffymo said it is not clear so i am going to post it again here. I am using Jama api for SVD calculation. I know very well about jama and SVD. Jama does not work if your column are more than rows. I have this situation. What should I do?? any help? I can't transpose the matrix too as it can produce wrong results. Thanks. P.S: I am calculating LSI with the help of jama. I am going like column(docs) and rows ( terms )

  • Strange TFS Source Repository Problem

    - by Brian
    We have a web project we are working on using TFS and we are kind of new to it (TFS). One of my teammates is unable to see a particular page (three associated files) in the IDE. To the rest of us, it looks as though it is checked out to her. When she ran the unlock command through the console, it returned that the files for the page were not locked. Yet we are unable to check it out due to her apparently having a lock. Any thoughts, ideas, or suggestions would be greatly appreciated!

  • cross domain iFrames communication problem

    - by Cyno
    I have a page A containing 2 children iFrames called B and C. A and B are on different domains. On pressing a button in B I would like to change C's URL. Based on the law III of Michael Mahemoff it should work, but in fact it doesn't (js security error). Here is the JS code in B: window.parent.frames['C'].location.href = "http://random.url";

Is this means that nhibernate doesnt escape special chars? if so how can i tell it to escape special chars globally?

  • Debugging a release only flash problem

    - by Fire Lancer
    I've got an Adobe Flash 10 program that freezes in certain cases, however only when running under a release version of the flash player. With the debug version, the application works fine. What are the best approaches to debugging such issues? I considered installing the release player on my computer and trying to set some kind of non-graphical method of output up (I guess there's some way to write a log file or similar?), however I see no way to have both the release and debug versions installed anyway :( . EDIT: Ok I managed to replace my version of flash player with the release version, and no freeze...so what I know so far is: Flash: Debug Release Vista 32: works works XP PRO 32: works* freeze I gave them the debug players I had to test this Hmm, seeming less and less like an error in my code and more like a bug in the player (10.0.45.2 in all cases)... At the very least id like to see the callstack at the point it freezes. Is there some way to do that without requiring them to install various bits and pieces, e.g. by letting flash write out a log.txt or something with a "trace" like function I can insert in the code in question? EDIT2: I just gave the swf to another person with XP 32bit, same results :(

  • Problem with socket communication between C# and Flex

    - by Chris Lee
    Hi all, I am implementing a simulated b/s stock data system. I am using flex and c# for client and server sides. I found flash has a security policy and I handled the policy-file-request in my server code. But seems it doesn't work, because the code jumped out at "socket.Receive(b)" after connection. I've tried sending message on client in the connection handler, in that case the server can receive correct message. But the auto-generated "policy-file-request" can never be received, and the client can get no data sending from server. Here I put my code snippet. my ActionScript code: public class StockClient extends Sprite { private var hostName:String = "192.168.84.103"; private var port:uint = 55555; private var socket:XMLSocket; public function StockClient() { socket = new XMLSocket(); configureListeners(socket); socket.connect(hostName, port); } public function send(data:Object) : void{ socket.send(data); } private function configureListeners(dispatcher:IEventDispatcher):void { dispatcher.addEventListener(Event.CLOSE, closeHandler); dispatcher.addEventListener(Event.CONNECT, connectHandler); dispatcher.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler); dispatcher.addEventListener(ProgressEvent.PROGRESS, progressHandler); dispatcher.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler); dispatcher.addEventListener(ProgressEvent.SOCKET_DATA, dataHandler); } private function closeHandler(event:Event):void { trace("closeHandler: " + event); } private function connectHandler(event:Event):void { trace("connectHandler: " + event); //following testing message can be received, but client can't invoke data handler //send("<policy-file-request/>"); } private function dataHandler(event:ProgressEvent):void { //never fired trace("dataHandler: " + event); } private function ioErrorHandler(event:IOErrorEvent):void { trace("ioErrorHandler: " + event); } private function progressHandler(event:ProgressEvent):void { trace("progressHandler loaded:" + event.bytesLoaded + " total: " + event.bytesTotal); } private function securityErrorHandler(event:SecurityErrorEvent):void { trace("securityErrorHandler: " + event); } } my C# code: const int PORT_NUMBER = 55555; const String BEGIN_REQUEST = "begin"; const String END_REQUEST = "end"; const String POLICY_REQUEST = "<policy-file-request/>\u0000"; const String POLICY_FILE = "<?xml version=\"1.0\"?>\n" + "<!DOCTYPE cross-domain-policy SYSTEM \"http://www.adobe.com/xml/dtds/cross-domain-policy.dtd\">\n" + "<cross-domain-policy> \n" + " <allow-access-from domain=\"*\" to-ports=\"55555\"/> \n" + "</cross-domain-policy>\u0000"; ................ private void startListening() { provider = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); provider.Bind(new IPEndPoint(IPAddress.Parse("192.168.84.103"), PORT_NUMBER)); provider.Listen(10); isListened = true; while (isListened) { Socket socket = provider.Accept(); Console.WriteLine("connect!"); byte[] b = new byte[1024]; int receiveLength = 0; try { // code jump out at this statement receiveLength = socket.Receive(b); } catch (Exception e) { Debug.WriteLine(e.ToString()); } String request = System.Text.Encoding.UTF8.GetString(b, 0, receiveLength); Console.WriteLine("request:"+request); if (request == POLICY_REQUEST) { socket.Send(Encoding.UTF8.GetBytes(POLICY_FILE)); Console.WriteLine("response:" + POLICY_FILE); } else if (request == END_REQUEST) { Dispose(socket); } else { StartSocket(socket); break; } } } Sorry for the long code, please someone help with it, thanks a million

    during installation i'm giving an option to user to change the default installation dir. Once this is done, installation goes fine and installs in the user specific location. But when i use INSTALLDIR to modify few registry entries, INSTALLDIR is having old, default values but not the user specified. This is happening to only one package and i couldn't find the reason. Any help will save my time. i use installshield 12 on win2k3 x86. ~calvin

  • Authentication problem with Wufoo

    - by fudgey
    I set up a Wufoo form with admin only portions that will only show up if I am logged in. I read through the Wufoo API documentation and I can get the authenication to work, but when I try to access the form after I authenticate, it says I need to authenticate. This is what I have so far (subdomain, api key & form id changed) <?php error_reporting(E_ALL); ini_set('display_errors', 1); $curl1 = curl_init('http://fishbowl.wufoo.com/api/v3/users.xml'); curl_setopt($curl1, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl1, CURLOPT_USERPWD, 'AOI6-LFKL-VM1Q-IEX9:footastic'); curl_setopt($curl1, CURLOPT_HTTPAUTH, CURLAUTH_ANY); curl_setopt($curl1, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($curl1, CURLOPT_FOLLOWLOCATION, false); curl_setopt($curl1, CURLOPT_USERAGENT, 'Wufoo Sample Code'); $response = curl_exec($curl1); $resultStatus = curl_getinfo($curl1); if($resultStatus['http_code'] == 200) { echo 'success!<br>'; } else { echo 'Call Failed '.print_r($resultStatus); } $curl2 = curl_init("http://fishbowl.wufoo.com/api/v3/forms/w7x1p5/entries.json"); curl_setopt($curl2, CURLOPT_HEADER, 0); curl_setopt($curl2, CURLOPT_RETURNTRANSFER, 1); $response = curl_exec($curl2); curl_close ($curl2); echo $response; curl_close($curl1); ?> It doesn't matter if I close $curl1 before or after I call $curl2, I get the same message on my screen: success! You must authenticate to get at the goodies. and I know the api, subdomain and form id are all correct. And one last bonus question... can I do all of this using Ajax instead? - the page I will be displaying the form on will already be limited to admin access, so exposing the API shouldn't matter.

  • Problem deploying Rails with Passenger to Mac OS X Leopard Server

    - by Meltemi
    I'm spinning my wheels... Apache is working and serving static html, png, etc. normally. Trying to get Passenger to serve a rails app out of www.mydomain.com/rails/ as it stands when i try to hit my app: www.mydomain.com/rails/myapp/railsclassname I get only an Apache 403 Errors. Nothing in myapp's Production Log. Apache2 access.log: "GET /rails/ HTTP/1.1" 403 1085 Apache2 error.log: [Fri Jun 11 22:44:01 2010] [error] [client 10.0.1.41] File does not exist: /Library/WebServer/wwwroot/rails/railsclassname i've even tried www.mydomain.com/myapp/classname Passenger, obviously, isn't routing requests made into my sub-folder rails/ to my rails app. not sure where i've screwed up. the most obvious thing is "Passenger doesn't seem to be running"... instructions I've followed just say to sudo apachectl graceful, which i've done (as well as stopped/started). new to this so go easy on me! Here's some info that might be helpful. happy to provide more as needed... As per some instruction @ Passenger site i've created a symlink from /Library/WebServer/myapp/rails - /Library/WebServer/rails/myapp/public myhost:myapp joe$ passenger-config --root /Library/Ruby/Gems/1.8/gems/passenger-2.2.14 myhost:myapp joe$ passenger-status ERROR: Phusion Passenger doesn't seem to be running. apollo:myapp joe$ cat /etc/httpd/httpd.conf ... <removed for brevity> ... # Copied From Passenger Installer LoadModule passenger_module /Library/Ruby/Gems/1.8/gems/passenger-2.2.14/ext/apache2/mod_passenger.so PassengerRoot /Library/Ruby/Gems/1.8/gems/passenger-2.2.14 PassengerRuby /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby # End Passenger Installer NameVirtualHost * <VirtualHost *:80> ServerName www.mydomain.com DocumentRoot /Library/WebServer/rails/myapp/public # <-- be sure to point to 'public'!

  • MVC 2 Data annotations problem

    - by Louzzzzzz
    Hi. Going mad now. I have a MVC solution that i've upgraded from MVC 1 to 2. It all works fine.... except the Validation! Here's some code: In the controller: using System; using System.Collections.Generic; using System.Globalization; using System.Linq; using System.Security.Principal; using System.Web; using System.Web.Mvc; using System.Web.Security; using System.Web.UI; using MF.Services.Authentication; using System.ComponentModel; using System.ComponentModel.DataAnnotations; namespace MF.Controllers { //basic viewmodel public class LogOnViewData { [Required] public string UserName { get; set; } [Required] public string Password { get; set; } } [HandleError] public class AccountController : Controller { [HttpPost] public ActionResult LogOn(LogOnViewData lvd, string returnUrl) { if (ModelState.IsValid) { //do stuff - IsValid is always true } } } } The ModelState is always valid. The model is being populated correctly however. Therefore, if I leave both username and password blank, and post the form the model state is still valid. Argh! Extra info: using structure map for IoD. Previously, before upgrading to MVC 2 was using the MS data annotation library so had this in my global.asax.cs: ModelBinders.Binders.DefaultBinder = new Microsoft.Web.Mvc.DataAnnotations.DataAnnotationsModelBinder(); Have removed that now. I'm sure i'm doing something really basic and wrong. If someone could point it out that would be marvellous. Cheers

  • C# WPF XAML Problem with icon in GridViewColumn

    - by Alex
    I've created a ListView with a GridView component in it. Now trying to fill one of the cells with an icon (PNG) like in the code sample below (save_icon.png): <ListView.View> <GridView> <GridViewColumn Header="Date" Width="Auto" DisplayMemberBinding="{Binding Date}" /> <GridViewColumn Header="Time" Width="Auto" DisplayMemberBinding="{Binding Time}" /> <GridViewColumn Header="FriendlyName" Width="Auto" DisplayMemberBinding="{Binding FriendlyName}" /> <GridViewColumn Width="Auto"> <Image Source="save_icon.png" /> </GridViewColumn> </GridView> </ListView.View> Visual Studio gives me an error on the line, where i put the icon into the column (ERROR: "Error 35: The file save_icon.png is not part of the project or its 'Build Action' property is not set to 'Resource'.") I added the icon to the project as a resource and when i start the app, everything works (the icon appears at the right place). But the WPF designer window can't be reloaded and i'm not able to see changes in the designer, when i change the XAML code. Can somebody explain this error or am i doing something wrong? Thanks for every hint in advance!

  • Problem retrieving values from Zend_Form_SubForms - no values returned

    - by anu iyer
    I have a Zend_Form that has 4 or more subforms. /** Code Snippet **/ $bigForm = new Zend_Form(); $littleForm1 = new Form_LittleForm1(); $littleForm1->setMethod('post'); $littleForm2 = new Form_LittleForm2(); $littleForm2->setMethod('post'); $bigForm->addSubForm($littleForm1,'littleForm1',0); $bigForm->addSubForm($littleForm2,'littleForm2',0); On clicking the 'submit' button, I'm trying to print out the values entered into the forms, like so: /** Code snippet, currently not validating, just printing **/ if($this-_request-getPost()){ $formData = array(); foreach($bigForm->getSubForms() as $subForm){ $formData = array_merge($formData, $subForm->getValues()); } /* Testing */ echo "<pre>"; print_r($formData); echo "</pre>"; } The end result is that - all the elements in the form do get printed, but the values entered before posting the form don't get printed. Any thoughts are appreciated...I have run around circles working on this! Thanks in advance!
