• Help Redirecting A Page to Another Page with adverts for 5 seconds, and then redirecting to another page.

  - by XcodeDev

  Hey, I am trying to redirect a page to another page, and that was working successfully. However I am trying to redirect the first page to another page with adverts. This page will then redirect to another page after five seconds. I am trying to do that by doing this: <?php include('ads.php'); ?> <?php sleep(2); $url = $_GET['url']; header("Location: ".$url.""); exit; ?> However it is showing the advert in ads.php perfectly, but it is not redirecting after five seconds. I am receiving this error in my web browser: Warning: Cannot modify header information - headers already sent by (output started at /home/nucleusi/public_html/adverts/ads.php:1) in /home/nucleusi/public_html/adverts/index.php on line 7 A typical link I would be redirecting to would be this: http://nucleusiphone.com/adverts/index.php/?url=http%3A%2F%2Fitunes.apple.com%2Fmx%2Falbum%2Fstill-got-the-blues%2Fid14135178%3Fi%3D14135158 Thanks in advanced. PS. I don't know any php so any code helps!

• Unable to delete inherited entity class in EF4

  - by Coding Gorilla

  I have two entities in an EF4 model (using Model First), let's call them EntityA and EntityB. EntityA is marked as abstract, and EntityB inherits from EntityA. They are similar to the following: public class EntityA { public Guid Id; public string Name; public string Uri; } public class EntityB : EntityA { public string AnotherProperty; } The generated database tables look as I would expect them, with EntityA as on table, and then another table like: EntityA_EntityB Id (PK, FK, uniqueidentifier) AnotherProperty (varchar) There is a foreign key constraint on EntityA_EntityB that references EntityA's Id property, no cascades are configured (although I did try changing these myself). The problem is that when I attempt to do something like: Context.DeleteObject(EntityA_EntityB); EF attempts to delete the EntityA_EntityB table record before deleting the EntityA table record, which of course violates the foreign key constraint on EntityA_EntityB table. Using EFProfiler I see the following commands being sent to the database: delete [dbo].[EntityA_EntityB] where (([Id] = '5c02899f-09ea-2ed9-d44b-01aef80f6b64' /* @0 */) followed by delete [dbo].[EntityA] where ([Id] = '5c02899f-09ea-2ed9-d44b-01aef80f6b64' /* @0 */) I'm completely stumped as to how to get around this problem. I would think the EF should know that it needs to delete the base class first, before deleting the inherited class. I know I could do some triggers or other database type solutions, but I'd rather avoid doing that if I can. All my classes are POCO built using some customized T4 templates. I don't want to paste in a lot of extraneous code, but if you need more information I'll provide what I can.

• Send email from webpage without postback/refresh

  - by jb

  Hi all. Long time reader, first time writer. Quick query i hope someone can help me with. I have a webpage (php, javascript) which has a small contact form for a user to fill in and email us. Not a problem in itself, i have a working form already. Nothing noteworthy, just a form posting to a php page which sends an email. <form id="myform" name="myform" method="post" action="Mailer.php"> So user fills in form, hits submit and the page changes to mailer.php and they find their way back to where they were. What I want instead is for the to stay on the same page when submit is pushed. The form div to update itself to just say 'message sent' or something. I just want to avoid a full page refresh. Much like how on say facebook, commenting on a status only updates that div. Hope that is phrased clearly enough. Cheers all,

• Sending custom app logs to developer

  - by Templar

  I'm planning to release a new app in the future. I have a custom logging function which logs some application data (not crashes) into a file (location manager state, app foreground-background transitions, main actions...). These logs helped me a lot to debug problems which were app-related, but not causing a crash. Until now these were in the documents directory (shared in iTunes) and the testers sent them to me after they saw some incorrect behaviors, however I don't want to share them anymore because this directory contains the app's database too. I'd like to obtain these logs even when the app will be on App Store, but I don't know how this should be done. As I wrote, it is a new app and even after the test phase may exist minor bugs. I know that the users can report problems in iTunes or on the Dev site, but without a detailed scenario or log it is really hard to correct a bug. Should I make some kind of in-app bug report functionality (even if this creates a wrong user impression) ? How is this usually handled ? Thanks

• IIS7.5 and MVC 2 : Implementing HTTP(S) security

  - by Program.X

  This is my first ASP.NET MVC application, and my first on an IIS 7.x installation whereby I have to do anything over and above the standard. I need to enforce Windows authentication on the /Index and /feeds/xxx.svc pages/services. In ASP.NET Web Forms, I would apply the Windows permissions on the files and remove Anonymous authentication in IIS 6. This needs to work over HTTP/S, but don't worry about that, that's in hand. What happens in MVC/IIS 7? I have tried modifying the permissions on the /Index.aspx view, which seems to block access. It asks me for a username/password, but does not grant access when I enter a valid username/password. Pressing Escape gives me an exception "*Access to the path 'E:\dev\xxx\xxx.ConsultantRegistration.Web.Admin\Views\ConsultantRegistration\index.aspx' is denied. *", which does get sent as a 401. So although the username/password does exist on the Index.aspx view, I can't use those credentials to access said view. I have in my web.config: What am I missing?

• 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.

• A beginner question on passthru() function in PHP

  - by Robert

  Hi all, I've used the following code to do an XSLT translation in PHP and save the result SVG file into a sub folder: $command = $java . $saxon . $target2 . ' ' . $xsl2.' '.$param; ob_start(); passthru($command, $result); $content_grabbed=ob_get_contents(); ob_end_clean(); $info = pathinfo($_FILES['file']['name']); $file_name= basename($_FILES['file']['name'],'.'.$info['extension']); $myFile = "images/convert/".$file_name."_".$_POST["mydropdown"].".svg"; $fh = fopen($myFile, 'w') or die("can't open file"); fwrite($fh, $content_grabbed); fclose($fh); It does a very simple SVG to SVG transformation, and created the resulting SVG file. the $command is just a simple java -jar saxon.jar input.xml stylesheet java command. The current situation is ,the file gets created perfectly, however, the error gets shown in browser, probably because I inserted the "ob_start" before passthru() command. I am thinking of making use of an argument that comes with the saxon.jar, that is "-o output_file_name". Because the final purpose is not to display the resulting SVG to the browser, but instead creating an SVG file ,and provide the link to the user for downloading. Are there any better ways to handle this problem, I am still thinking about how to get rid of the result that gets shown in the browser that is sent by the "passthru()". Thanks in advance for suggestions!

• What's the *right* way to handle a POST in FP?

  - by Malvolio

  I'm just getting started with FP and I'm using Scala, which may not be the best way, since I can always fall back to an imperative style if the going gets tough. I'd just rather not. I've got a very specific question that points to a broader lacuna in my understanding of FP. When a web application is processing a GET request, the user wants information that already exists on the web-site. The application only has to process and format the data in some way. The FB way is clear. When a web application is processing a POST request, the user wants change the information held on the site. True, the information is not typically held in application variables, it's in a database or a flat-file, but still, I get the feeling I'm not grokking FP properly. Is there a pattern for handling updates to static data in an FP language? My vague picture of this is that the application is handed the request and the then-current site state. The application does its thing and returns the new site-state. If the current site-state hasn't changed since the application started, the new state becomes the current state and the reply is sent back to the browser (this is my dim image of Clojure's style); if the current state has been changed (by another thread, well, something else happens ...

• Wordpress Contact Form 7 in a hidden div.

  - by Luke

  Hi there, I'm using Contact Form 7 on Wordpress. I have it set up so the upload appears in the 3rd of three divs that hide and show depending on a clicked link. Everything is fine except when I click submit it hides the uploads div and shows the first div again. The form is submitting fine and you see a message that it has sent if you navigate back to the uploads section. Is there any way to keep the div you're in open and keep the rest hidden on submit? This is the code i'm using for hiding and showing. I'm sure it's not perfect but it works. // My Files function basic_myfiles($atts, $content = null) { return '' . $content . ''; } add_shortcode("myfiles", "basic_myfiles"); // Sound Library function basic_soundlib($atts, $content = null) { return '' . $content . ''; } add_shortcode("soundlib", "basic_soundlib"); // Uploads function basic_uploads($atts, $content = null) { return '' . $content . do_shortcode( '[contact-form 4 "Client Upload Form"]' ) . ''; } add_shortcode("uploads", "basic_uploads"); Thanks

• How to convert a byte array of 19200 bytes in size where each byte represents 4 pixels (2 bits per p

  - by Klinger

  I am communicating with an instrument (remote controlling it) and one of the things I need to do is to draw the instrument screen. In order to get the screen I issue a command and the instrument replies with an array of bytes that represents the screen. Below is what the instrument manual has to say about converting the response to the actual screen: The command retrieves the framebuffer data used for the display. It is 19200 bytes in size, 2-bits per pixel, 4 pixels per byte arranged as 320x240 characteres. The data is sent in RLE encoded form. To convert this data into a BMP for use in Windows, it needs to be turned into a 4BPP. Also note that BMP files are upside down relative to this data, i.e. the top display line is the last line in the BMP. I managed to unpack the data, but now I am stuck on how to actually go from the unpacked byte array to a bitmap. My background on this is pretty close to zero and my searches have not revealed much either. I am looking for directions and/or articles I could use to help me undestand how to get this done. Any code or even pseudo code would also help. :-) So, just to summarize it all: How to convert a byte array of 19200 bytes in size, where each byte represents 4 pixels (2 bits per pixel), to a bitmap arranged as 320x240 characters. Thanks in advance.

• Low Throughput on Windows Named Pipe Over WAN

  - by MichaelB76

  I'm having problems with low performance using a Windows named pipe. The throughput drops off rapidly as the network latency increases. There is a roughly linear relationship between messages sent per second and round trip time. It seems that the client must ack each message before the server will send the next one. This leads to very poor performance, I can only send 5 (~100 byte) messages per second over a link with an RTT of 200 ms. The pipe is asynchronous, using multiple overlapped write operations (and multiple overlapped reads at the client end), but this is not improving throughput. Is it possible to send messages in parallel over a named pipe? The pipe is created using PIPE_TYPE_MESSAGE, would PIPE_READMODE_BYTE work better? Is there any other way I can improve performance? This is a deployed solution, so I can't simply replace the pipe with a socket connection (I've read that Windows named pipe aren't recommended for use over a WAN, and I'm wondering if this is why). I'd be grateful for any help with this matter.

• What does an object look like in memory?

  - by NeilMonday

  This is probably a really dumb question, but I will ask anyway. I am curious what an object looks like in memory. Obviously it would have to have all of its member data in it. I assume that functions for an object would not be duplicated in memory (or maybe I am wrong?). It would seem wasteful to have 999 objects in memory all with the same function defined over and over. If there is only 1 function in memory for all 999 objects, then how does each function know who's member data to modify (I specifically want to know at the low level). Is there an object pointer that gets sent to the function behind the scenes? Perhaps it is different for every compiler? Also, how does the static keyword affect this? With static member data, I would think that all 999 objects would use the exact same memory location for their static member data. Where does this get stored? Static functions I guess would also just be one place in memory, and would not have to interact with instantiated objects, which I think I understand.

• Python programming - Windows focus and program process

  - by Zack

  I'm working on a python program that will automatically combine sets of files based on their names. Being a newbie, I wasn't quite sure how to go about it, so I decided to just brute force it with the win32api. So I'm attempting to do everything with virtual keys. So I run the script, it selects the top file (after arranging the by name), then sends a right click command,selects 'combine as adobe PDF', and then have it push enter. This launched the Acrobat combine window, where I send another 'enter' command. The here's where I hit the problem. The folder where I'm converting these things loses focus and I'm unsure how to get it back. Sending alt+tab commands seems somewhat unreliable. It sometimes switches to the wrong thing. A much bigger issue for me.. Different combination of files take different times to combine. though I haven't gotten this far in my code, my plan was to set some arbitrarily long time.sleep() command before it finally sent the last "enter" command to finish and confirm the file name completing the combination process. Is there a way to monitor another programs progress? Is there a way to have python not execute anymore code until something else has finished?

• Windows Azure Worldwide availability

  - by Insomniac

  Hi, I've been reviewing Windows Azure platform for some time, and can't find answer to one very important question. If I deploy my application within a cloud, how it will be reached from different places worldwide? For example if I have a web application with a database and want it to be accessible to users in UK, US, China and etc. Can I be sure that any user in the world will get almost the same request processing time? I think of it this way. 1. User sends request (navigates in browser to my web site) 2. This request gets in a cloud in a nearest location (closest to user MS Data Center?) 3. It is processed by an instance of my web application (in nearest location, with request to my centralized DB which can be far away but SQL request goes via MS internal network, which I believe should be very fast). 4. Response sent to user. Please let me know if I'm wrong. Thanks.

• Best practice on structuring asynchronous mailers (using Sidekiq)

  - by gbdev

  Just wondering what's the best way to go about structuring asynchronous mailers in my Rails app (using Sidekiq)? I have one ActionMailer class with multiple methods/emails... notifier.rb: class Notifier < ActionMailer::Base default from: "\"Company Name\" <[email protected]>" default_url_options[:host] = Rails.env.production? ? 'domain.com' : 'localhost:5000' def welcome_email(user) @user = user mail to: @user.email, subject: "Thanks for signing up!" end ... def password_reset(user) @user = user @edit_password_reset_url = edit_password_reset_url(user.perishable_token) mail to: @user.email, subject: "Password Reset" end end Then for example, the password_reset mail is sent in my User model by doing... user.rb: def deliver_password_reset_instructions! reset_perishable_token! NotifierWorker.perform_async(self) end notifier_worker.rb: class NotifierWorker include Sidekiq::Worker sidekiq_options queue: "mail" def perform(user) Notifier.password_reset(user).deliver end end So I guess I'm wondering a couple things here... Is it possible to define many "perform" actions in one single worker? By doing so I could keep things simple (one notifier/mail worker) as I have it and send many different emails through it. Or should I create many workers? One for each mailer (e.g. WelcomeEmailWorker, PasswordResetWorker, etc) and just assign them all to use the same "mail" queue with Sidekiq. I know it works as it is, but should I break out each of those mail methods (welcome_email, password_reset, etc) into individually mailer classes or is it ok to have them all under one class like Notifier? Really appreciate any advice here. Thanks!

• Manipulating/changing adressbar link Help

  - by Karem

  I am out of my own "ideas" going through this. I have a album viewer. When you click next I want the adressbar to hang with it, e.g if you start on ?photoid=1, and click next (next picture appends and stuff), and then i want it to say ?photoid=2. Now I cant make it say ?photoid=2 without changing/manipulating, and this you cant do without HTML5. I have made a script in HTML5 that works fine, but then I need to take care of those who dont have HTML5(only chrome, ff4 etc supports html5) Made the script from this( https://developer.mozilla.org/en/DOM/Manipulating_the_browser_history ) I thought of adding #photoid=2 so, ?photoid=1#photoid=2 and then check if theres anything in # then use that instead of the $_GET.. But apparently you cannot do that as # is client side handled and never sent to the server. So what should I then do? Any suggestions please to make a workaround this? I checked facebook, what they did to IE users, and I could hear that it "clicked" (the annoying click sound from IE) twice.. the first was to get to the next picture, the second click sound changed the adressbar?!(how?). And then I also thought hey, html5 is only supported in ff4, and I got ff3.6, and they manipulate the adress bar url when you browse through the album photos, exactly like how I wanted (and what I have written for but it only works in Chrome and ff4..?). How could they do that?

• Choosing approach for an IM client-server app

  - by John

  Update: totally re-wrote this to be more succint. I'm looking at a new application, one part of which will be very similar to standard IM clients, i.e text chat, ability to send attachments, maybe some real-time interaction like a multi-user whiteboard. It will be client-server, i.e all traffic goes through my central server. That means if I want to support cross-communication with other IM systems, I am still free to pick any protocol for my own client<--server communication - my server can use XMPP or whatever to talk to other systems. Clients are expected to include desktop apps, but probably also browser-based as well either through Flex/Silverlight or HTML/AJAX. I see 3 options for my own client-server communication layer: XMPP. The benefits are clients already exist as do open-source servers. However it requires the most up-front research/learning and also appears like it might raise legal issues due to GPL. Custom sockets. A server app makes connections with the clients, allowing any text/binary data to be sent very fast. However this approach requires building said server from scratch, and also makes a JS client tricky Servlets (or similar web server). Using tried and tested Java web-stack, clients send HTTP requests similar to AJAX-based websites. The benefit is the server is easy to write using well-established technologies, and easy to talk to. But what restrictions would this bring? Is it appropriate technology for real-time communication? Advice and suggests are welcome, especially what pros and cons surround using a web-server approach as compared to a socket-based approach.

• VB6 ActiveX exe - what is the proper registration sequence?

  - by Timbuck

  I have recently updated a Visual Basic 6 application that is an ActiveX exe, running on Windows XP. I have a couple of testers for this application who have received a copy of the exe and are attempting to run it. However, they are getting an error message "Unexpected error;quitting" when trying to do so. A key difference between their testing and my testing is that on the machines I tested on, I have admin rights and was able to register the application using the appname.exe /regserver command line. Reading the details at MS Support about file registration appears unclear: Visual Basic ActiveX EXE files register themselves the first time you run the EXE. However, you cannot use the EXE as a COM server until it is registered. So does this mean that after the first time the users run the exe that the application should be correctly registered, and the error I am receiving is sign of something other than an incorrectly registered application? Or does this mean that the application will not work properly until such time as the file is explicitly registered using the appname.exe /regserver command line? nb - during a production distribution, the software would be sent out to client PCs using Systems Management Server, which isn't an option for this testing.

• PHP: parse $_FILES[] data in multidimesional array

  - by superUntitled

  I having been looking around for an answer to this and have not found an answer anywhere, I am hoping someone has done this before! I have a form that allows for dynamic duplication of the form fields. The form allows for file uploads and text input, so the data is sent in both $_POST and $_FILES arrays. The the initial set of inputs look like this: <input type="text" name="primary[1][text]" /> <input type="file" name="primary[1][file]" /> <input type="text" class="a" name="secondary[1][text][]" /> <input type="file" name="secondary[1][file][]" /> When duplicated the fields are incremented, they look like this: <input type="text" name="primary[2][text]" /> <input type="file" name="primary[2][file]" /> <input type="text" class="a" name="secondary[2][text][]" /> <input type="file" name="secondary[2][file][]" /> To complicate matters, the "secondary" form fields can also be duplicated (thus the [] at the end of the secondary name array. How can I parse the posted $_FILES array? I have tried something like this: foreach ($_FILES['question'] as $f_num) { echo $f['file']['name']; } but I get an "Undefined index: file... " error.

• Event Dispatching, void pointer and alternatives

  - by PeeS

  i have my event dispatching / handling functionality working fine, but there is one issue that i need to resolve. Long story short, here are the details. // The event structure struct tEventMessage { // Type of the event int Type; // (void*) Allows those to be casted into per-Type objects void *pArgument1; void *pArgument2; }; I am sending events from different modules in my engine by using the above structure, which requires a pointer to an argument. All messages are queued, and then dispatched on the next ::Tick(). It works fine, untill i try to send something that doesn't exist in next ::Tick, for example: When a mouse click is being handled, it calculates the click coordinates in world space. This is being sent with a pointer to a vector representing that position, but after my program quits that method, this pointer gets invalid obviously, cause local CVector3 is destructed: CVector2 vScreenSpacePosition = vAt; CVector3 v3DPositionA = CVector3(0,0,0); CVector3 v3DPositionB = CVector3(0,0,0); // Screen space to World space calculation for depth zNear v3DPositionA = CMath::UnProject(vScreenSpacePosition, m_vScreenSize, m_Level.GetCurrentCamera()->getViewMatrix(), m_Level.GetCurrentCamera()->getProjectionMatrix(), -1.0 ); // Screen space to World space calculation for depth zFar v3DPositionB = CMath::UnProject(vScreenSpacePosition, m_vScreenSize, m_Level.GetCurrentCamera()->getViewMatrix(), m_Level.GetCurrentCamera()->getProjectionMatrix(), 1.0); // Send zFar position and ScreenSpace position to the handlers // Obviously both vectors won't be valid after this method quits.. CEventDispatcher::Get()->SendEvent(CIEventHandler::EVENT_SYSTEM_FINGER_DOWN, static_cast<void*>(&v3DPositionB), static_cast<void*>(&vScreenSpacePosition)); What i want to ask is, if there is any chance i could make my tEventMessage more 'template', so i can handle sending objects like in the above situation + use what is already implemented? Can't figure it out at the moment.. What else can be done here to allow me to pass some locally available data ? Please can somebody shed a bit of light on this please?

• redirect web app results to own application

  - by vbNewbie

  Is it possible to redirect a web apps results to a second application? I cannot parse the html source. It contains the javascript functions that execute the queries but all the content is probably server side. I hope this makes sense. The owner has made the script available but I am not sure how this helps. Can I using .net call the site and redirect results perhaps to a file or database? the app accesses one of googles apis and performs searches/queries and returns results which are displayed on the site. Now all the javascript functions that perform these queries are listed in the source but I do not know javascript so it does not make much sense to me. I have used the documentation which uses the oauth protocol to access the api and have implemented that in my web app but it took me nearly a week to get the request token right and now to send requests to the api, sometimes I get one result back and sometimes none. It is frustrating me and the owner of the web app has given use of his script but he says all that happens is that my browser interacts with the google api and not his server. So I thought why not have my web app call his, since his interacts with the API flawlessly and have the results sent to my app to save in a database. I have very little experience here so pardon my ignorance

• How can I [simply] consume JSON Data in a Line of Business Web Application

  - by Atomiton

  I usually use JSON with jQuery to just return a string with html. However, I want to start to use Javascript objects in my code. What's the simplest way to get started using json objects on my page? Here's a sample Ajax call ( after $(document).ready( { ... }) of course: $('#btn').click(function(event) { event.preventDefault(); var out = $('#result'); $.ajax({ url: "CustomerServices.asmx/GetCustomersByInvoiceCount", success: function(msg) { // // Iterate through the json results and spit them out to a page? // }, data: "{ 'invoiceCount' : 100 }" }); }); My WebMethod: [WebMethod(Description="Gets customers with more than n invoices")] public List<Customer> GetCustomersByInvoiceCount(int? invoiceCount) { using (dbDataContext db = new dbDataContext()) { return db.Customers.Where(c => c.InvoiceCount >= invoiceCount); } } What gets returned: {"d":[{"__type":"Customer","Account":"1116317","Name":"SOME COMPANY","Address":"UNit 1 , 392 JOHN ST. ","LastTransaction":"\/Date(1268294400000)\/","HighestBalance":13922.34},{"__type":"Customer","Account":"1116318","Name":"ANOTHER COMPANY","Address":"UNIT #345 , 392 JOHN ST. ","LastTransaction":"\/Date(1265097600000)\/","HighestBalance":549.42}]} What I'd LIKE to know, is what are people generally doing with this returned json? Do you iterate through the properties and create an html table on the fly? Is there way to "bind" JSON data using a javascript version of reflection ( something like the .Net GridView Control ) Do you throw this returned data into a Javascript Object and then do something with it? An example of what I want to achieve is to have an plain ol' html page ( on a mobile device )with a list of a Salesperson's Customers. When one of those customers are clicked, the customer id gets sent to a webservice which retrieves the customer details that are relevant to a sales person. I know the SO talent pool is quite deep so I figured you all here would be able to guide in the right direction and give me a few ideas on the best way to approach this.

• issue with tab bar view displaying a compound view

  - by ambertch

  I created a tab bar application, and I make the first tab a table. So I create a tableView controller, and go about setting the class identity of the view controller for the first tab to my tableView controller. This works fine, and I see the contents of the table filling up the whole screen. However, this is not what I actually want in the end goal - I would like a compound window having multiple views: - the aforementioned table - a custom view with data in it So what I do is create a nib for this content (call it contentNib), change the tab's class from the tableView controller to a generic UIViewController, and set the nib of that tab to this new contentNib. In this new contentNib I drag on a tableView and set File's Owner to the TableViewController. I then link the dataSource and delegate to file's owner (which is TableViewController). Surprisingly this does not work and I receive the error: **Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIViewController tableView:numberOfRowsInSection:]: unrecognized selector sent to instance 0x3b0f910'** This is bewildering to me since the file's owner is the TableViewController, which has been assigned to be both the dataSource and delegate. Does someone have either insight into my confusions, or a link to an example of how to have a compound view include a tableView? *update* I see this in the Apple TableView programming guide: "Note: You should use a UIViewController subclass rather than a subclass of UITableViewController to manage a table view if the view to be managed is composed of multiple subviews, one of which is a table view. The default behavior of the UITableViewController class is to make the table view fill the screen between the navigation bar and the tab bar (if either are present)." <----- I don't really get what this is telling me to do though... if someone can explain or point me to an example I'd be much appreciated!

• PHP: parse $_FILES[] data in multidimesional array

  - by superUntitled

  Example form here: http://jsfiddle.net/superuntitled/uaTtx/1/ I have a form that allows for dynamic duplication of the form fields. The form allows for file uploads and text input, so the data is sent in both $_POST and $_FILES arrays. The the initial set of inputs look like this: <input type="text" name="question[1][text]" /> <input type="file" name="question[1][file]" /> <input type="text" class="a" name="answer[1][text][]" /> <input type="file" name="answer[1][file][]" /> When duplicated the fields are incremented, they look like this: <input type="text" name="question[2][text]" /> <input type="file" name="question[2][file]" /> <input type="text" class="a" name="answer[2][text][]" /> <input type="file" name="answer[2][file][]" /> To complicate matters, the "answer" form fields can also be duplicated (thus the [] at the end of the 'answer' name array. How can I parse the posted $_FILES array? I have tried something like this: foreach ($_FILES['question'] as $p_num) { echo $p_num['file']['name']; foreach ($_FILES['answer'] as $a_num) { echo $a_num['file']['name']; } } but I get an "Undefined index: file... " error. How can I parse out the posted values.

• Write to PDF using PHP from android device

  - by Brent Mitchell

  I am trying to write to a pdf file on php server. I have sent variables to the server, create the pdf document, then have my phone download the document to view on device. The variables seem not to write on the php file. I have my code below public void postData() { try { Calculate calc = new Calculate(); HttpClient mClient = new DefaultHttpClient(); StringBuilder sb=new StringBuilder("myurl.com/pdf.php"); HttpPost mpost = new HttpPost(sb.toString()); String value = "1234"; List nameValuepairs = new ArrayList(1); nameValuepairs.add(new BasicNameValuePair("id",value)); mpost.setEntity(new UrlEncodedFormEntity(nameValuepairs)); } catch (UnsupportedEncodingException e) { Log.w(" error ", e.toString()); } catch (Exception e) { Log.w(" error ", e.toString()); } } And my php code to write the variable "value" onto the pdf document: //code to reverse the string if($_POST[] != null) { $reversed = strrev($_POST["value"]); $this->SetFont('Arial','u',50); $this->Text(52,68,$reversed); } I am just trying to write the variable in a random spot, but the variable the if statement is always null and I do not know why. Thanks. Sorry if it is a little sloppy.
