  • C# TCP socket with session

    - by Zé Carlos
    Is there any way of dealing with sessions with sockets in C#? Example of my problem: I have a server with a socket listening on port 5672. TcpListener socket = new TcpListener(localAddr, 5672); socket.Start(); Console.Write("Waiting for a connection... "); // Perform a blocking call to accept requests. TcpClient client = socket.AcceptTcpClient(); Console.WriteLine("Connected to client!"); And i have two clients that will send one byte. Client A send 0x1 and client B send 0x2. From the server side, i read this data like this: Byte[] bytes = new Byte[256]; String data = null; NetworkStream stream = client.GetStream(); while ((stream.Read(bytes, 0, bytes.Length)) != 0) { byte[] answer = new ... stream.Write(answer , 0, answer.Length); } Then client A sends 0x11. I need a way to know that this client is the same that sent "0x1" before.

  • List of models in Model in MVC

    - by arri
    I have two models: class ModelIn{ public string FirstName { get; set; } public string LastName { get; set; } public string Address { get; set; } } class ModelOut{ public ModelOut(){ People = new List<ModelIn>();} public List<ModelIn> People { get; private set;} public string Country { get; set; } } And I have Controller editing ModelOut: public ActionResult People() { ... return View(SomeModelOutInstanceWith3People); } [HttpPost] public ActionResult(ModelOut m) { ... } In view I have sth like: <% using (Html.BeginForm()) { %> <%: Html.EditorFor(m => Model.Country) %> <% for(int i = 0; i < Model.People.Count; ++i){ %> <%: Html.EditorFor(m => Model.People[i].FirstName) %> <%: Html.EditorFor(m => Model.People[i].LastName) %> <%: Html.EditorFor(m => Model.People[i].Address) %> <% } %> <input type="submit" /> <% } %> It works all OK, but in post action I have empty ModelOut m. I can see in logs that data is sent correctly. I have tried everything, nothing works.

  • E-Commerce Security: Only Credit Card Fields Encrypted?!

    - by bizarreunprofessionalanddangerous
    I'd like your opinions on how a major bricks-and-mortar company is running the security for its shopping Web site. After a recent update, when you are logged into your shopping account, the session is now not secured. No 'https', no browser 'lock'. All the personal contact info, shopping history -- and if I'm not mistaken submit and change password -- are being sent unencrypted. There is a small frame around the credit card fields that is https. There's a little notice: "Our website is secure. Our website uses frames and because of this the secure icon will not appear in your browser" On top of this the most prominent login fields for the site are broken, and haven't gotten fixed for a week or longer (giving the distinct impression they have no clue what's going on and can't be trusted with anything). Now is it just me -- or is this simply incomprehensible for a billion dollar company, significant shopping site, in the year 2010. No lock. "We use frames" (maybe they forget "Best viewed in IE4"). Customers complaining, as you can see from their FAQ "explaining" why you aren't seeing https. I'm getting nowhere trying to convince customer service that they REALLY need to do something about this, and am about to head for the CEO. But I just want to make sure this is as BIZARRE and unprofessional and dangerous a situation as I think it is. (I'm trying to visualize what their Web technical team consists of. I'm getting A) some customer service reps who were given a 3 hour training course on Web site maintenance, B) a 14 year old boy in his bedroom masquerading as a major technical services company, C) a guy in a hut in a jungle with an e-commerce book from 1996.)

  • In app purchase on iphone.: How to receive your available products *before* someone may be able to b

    - by Thorsten S.
    Currently I am loading my supported products from a plist and after that I send a SKProductsRequest to guarantee that my SKProducts are still valid. So I set up the request, start it and get the response in: (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response Now, so far all functions correctly. Problem: From calling the request until receiving the response it may last several seconds. Until that my app is already loaded and the user may be able to choose and buy a product. But because no products have been received, the available products are not in sync with the validated products - unlikely, but possible error. So my idea is to wait until the data is loaded and only continue when the list is validated. (Just a few seconds waiting...). I have a singleton instance managing all products. + (MyClass *) sharedInstance { if (!sharedInstance) sharedInstance = [MyClass new]; // Now wait until we have our data [condition lock]; while (noEntriesYet) // is yes at begin [condition wait]; [condition unlock]; return sharedInstance; } - productsRequest: didReceiveResponse: { [condition lock]; // I have my data noEntriesYet = false; [condition signal]; [condition unlock]; } Problem: The app freezes. Everything works fine if didReceiveResponse is completed before the sharedInstance is queried. There are different threads, the lock is working if wait is reached during didReceiveResponse, everything fine. But if not, didReceiveResponse is never called even if the request was sent. The lock is released, everything looks ok. I have tried to send the product request in a separate NSThread, with NSOperationQueue...without avail. Why ? What is happening ? How to solve the problem ?

  • Manage multiple UDP calls

    - by rayman
    Hi all, I would like to have an advice for this issue: I am using Jbos 5.1.0, EJB3.0 I have system, which sending requests via UDP'S to remote modems, and suppose to wait for an answer from the target modem. the remote modems support only UDP calls, therefor I o design asynchronous mechanism. (also coz I want to request X modems parallel) this is what I try to do: all calls are retrieved from Data Base, then each call will be added as a message to JMS QUE. let's say i will set X MDB'S on that que, so I can work asynchronous. now each MDB will send UDP request to the IP-address(remote modem) which will be parsed from the que message. so basicly each MDB, which takes a message is sending a udp request to the remote modem and [b]waiting [/b]for an answer from that modem. [u]now here is the BUG:[/u] could happen a scenario where MDB will get an answer, but not from the right modem( which it requested in first place). that bad scenario cause two wrong things: a. the sender which sent the message will wait forever since the message never returned to him(it got accepted by another MDB). b. the MDB which received the message is not the right one, and probablly if it was on a "listener" mode, then it supposed to wait for an answer from diffrent sender.(else it wouldnt get any messages) so ofcourse I can handle everything with a RETRY mechanisem. so both mdb's(the one who got message from the wrong sender, and the one who never got the answer) will try again, to do thire operation with a hope that next time it will success. This is the mechanism, mybe you could tell me if there is any design pattren, or any other effective solution for this problem? Thanks, ray.

  • Ajax heavy JS apps using excessive amounts of memory over time.

    - by Shane Reustle
    I seem to have some pretty large memory leaks in an app that I am working on. The app itself is not very complex. Every 15 seconds, the page requests approx 40kb of JSON from the server, and draws a table on the page using it. It is cheaper to draw the table over because the data is usually always new. I am attaching a few events to the table, approx 5 per line, 30 lines in the table. I used jQuery's .html() method to put the new html into the container and overwrite the existing. I do this specifically so that jQuery's special cleanup functions go in and attempt to detach all events on the elements in the element that it is overwriting. I then also delete the large variables of html once they are sent to the DOM using delete my_var. I have checked for circular references and attached events that are never cleared a few times, but never REALLY dug into it. I was wondering if someone could give me a few pointers on how to optimize a very heavy app like this. I just picked up "High Performance Javascript" by Nicholas Zakas, but didn't have much time to get into it yet. To give an idea on how much memory this is using, after 4~ hours, it is using about 420,000k on chrome, and much more on Firefox or IE. Thanks!

  • Django notification get date one accesses a link

    - by dana
    hi there, i'm making a notification system, so that a user in a virtual community to be announced when someone sends him a message, or starts following him (the follow relation is like a friend relation, but it is not necessarily reciprocal) my view function: def notification_view(request, last_checked): u = Relation.objects.filter(date_follow>Notification.objects.get(last_checked=last_checked)) v = Message.objects.filter(date>Notification.objects.get(last_checked=last_checked)) if u: notification_type = follow if notice_settings == receive_notification or notice_settings == only_follow following = u if v: notification_type = message if notice_settings == receive_notification or notice_settings == only_messages message = v return render_to_response('notification/notification.html', { 'following': following, 'message':message, }, context_instance=RequestContext(request)) the models.py: class NoticeType(models.Model): follow = models.ForeignKey(Relations, editable = False) message = models.ForeignKey(Messages) classroom_invitation = models.ForeignKey(Classroom) class Notification(models.Model): receiver = models.ForeignKey(User, editable=False) date = models.DateTimeField(auto_now=True, editable = False) notice_type = models.ForeignKey(NoticeType, editable = False, related_name = "notification_type") sent = models.BooleanField(default = True) last_checked = models.DateTimeField(auto_now=True, editable = False) class NotificationSettings(models.Model): user = models.ForeignKey(User) receive_notifications = models.BooleanField(default = True) only_follow = models.BooleanField(default = False) only_message = models.BooleanField(default = False) only_classroom = models.BooleanField(default = False) #receive_on_email = models.BooleanField(default = False) my problem is: i want last_checked to be the time when someone acceses a link (the notification link). How can i possibily save that time? how can i get it? thanks in avance!

  • Google App Engine, parsedatetime and TimeZones

    - by Ron
    Hey guys, I'm working on a Google App Engine / Django app and I encountered the following problem: In my html I have an input for time. The input is free text - the user types "in 1 hour" or "tomorrow at 11am". The text is then sent to the server in AJAX, which parses it using this python library: http://code.google.com/p/parsedatetime/. Once parsed, the server returns an epoch timestamp of the time. Here is the problem - Google App Engine always runs on UTC. Therefore, lets say that the local time is now 11am and the UTC time is 2am. When I send "now" to the server it will return "2am", which is good because I want the date to be received in UTC time. When I send "in 1 hour" the server will return "3am" which is good, again. However, when I send "at noon" the server will return "12pm" because it thinks that I'm talking about noon UTC - but really I need it to return 3am, which is noon for the request sender.. I can pass on the TZ of the browser that sends the request, but that wont really help me - the parsedatetime library wont take a timezone argument (correct me if I'm wrong). Is there a walk around this? Maybe setting the environments TZ somehow? Thanks!

  • Login page shows blank

    - by user481913
    The login page on a project i'm currently fixing up shows blank. i tried echoing some words to find out where the fault lied. I found out that commenting out the below piece of code made it to display. elseif( isset($_POST['do_login'] ) ){//Login user $email = (isset($_POST['login']) && is_string($_POST['login']) && strlen($_POST['login'])<100)?$_POST['login'] : null; $password = (isset($_POST['password']) && is_string($_POST['password']) && strlen($_POST['password'])<100)?$_POST['password'] : null; $remember = isset($_POST['chkremember']) ? true : false; $result = $auth->login($email, $password, $remember); switch($result){ case 1: $msg = 'You have successfully logged in.' break; case 2: $msg = 'Your account has not yet been confirmed. <br/> Please check the e-mail message sent by us and click the confirmation code to validate this account. <a href="user_login.php?view=resend&resend_email='.$email.'">resend activation e-mail</a>'; break; case 3: $msg = 'Your account is not enabled!'; break; case 4: $msg = 'Account with given login credentials does not exist!'; break; } } Can anyone help me figiure out what's wrong with this piece of code?

  • Action Mailer: How do I render dynamic data in an email body that is stored in the database?

    - by Brandon Toone
    I have Action Mailer setup to render an email using the body attribute of my Email model (in the database). I want to be able to use erb in the body but I can't figure out how to get it to render in the sent email message. I'm able to get the body as a string with this code # models/user_mailer.rb def custom_email(user, email_id) email = Email.find(email_id) recipients user.email from "Mail It Example <[email protected]>" subject "Hello From Mail It" sent_on Time.now # pulls the email body and passes a string to the template views/user_mailer/customer_email.text.html.erb body :msg => email.body end I came across this article http://rails-nutshell.labs.oreilly.com/ch05.html which says I can use render but I'm only able to get render :text to work and not render :inline # models/user_mailer.rb def custom_email(user, email_id) email = Email.find(email_id) recipients user.email from "Mail It Example <[email protected]>" subject "Hello From Mail It" sent_on Time.now # body :msg => email.body body :msg => (render :text => "Thanks for your order") # renders text and passes as a variable to the template # body :msg => (render :inline => "We shipped <%= Time.now %>") # throws a NoMethodError end

  • Uploading Binary iPhone App "The signature was invalid" again again and again...

    - by user338386
    Hello! I'm going crazy! I'm trying to upload the binary of my first application but I have always the same error! "The binary you uploaded was invalid. The signature was invalid, or it was not signed with an Apple submission certificate." I did everything, EVERYTHING!! I created the request for the certificate, used it for both developer and distribution certificate, created the provisioning profile (12 times!!!) always cleaning my keychain and my Xcode deleting the old certificates and profiles.. I reboot the machine, reboot Xcode, the log is correct, but... I can't upload my app!!!! Checked if my iPhone is connected (i tried with iPhone disconneted too). I checked the certificate in both my project settings "Distribuition" Configuration (duplicate of "Release" configuration) and in my target settings. Reveal in finder, compress the app and sent the zip... I tried with Application Loader and iTunes connect online.. but nothing! NOTHING!! I've spent 8 hours! And again i can't have my app uploaded!!! I'm really going crazy! Can anyone help me pleeease? Thx!

  • how to make an import library

    - by user295030
    a requirement was sent to me below: API should be in the form of static library. company xxx will link the library into a third party application to prevent any possible exposure of the code(dll) could they mean an import library? An import library is a library that automates the process of loading and using a dynamic library. On Windows, this is typically done via a small static library (.lib) of the same name as the dynamic library (.dll). The static library is linked into the program at compile time, and then the functionality of the dynamic library can effectively be used as if it were a static library. this might be what they might be eluding to.....I am not sure how to make this in vs2008 . Additional facts: I have a static lib that i use in my current application. Now, I have to convert my app that uses that static lib into an import lib so that they can use a third party prog to access the API's they providede me which in turn will use that static lib i am using. I hope I am clearly explaining this. I am just not sure how to go about it in vs2008. I am looking for specific steps to do this. I already have the coding done. Just need to convert it into the form they are asking and I have to provide the API they want. Other than that then I need to create a test prog which will act as that third party prog so I can make sure my import library works.

  • multiple ajax requests with jquery

    - by Emil
    I got problems with the async nature of Javascript / JQuery. Lets say the following (no latency is counted for, in order to not make it so troublesome); I got three buttons (A, B, C) on a page, each of the buttons adds an item into a shopping cart with one ajax-request each. If I put an intentional delay of 5 seconds in the serverside script (PHP) and pushes the buttons with 1 second apart, I want the result to be the following: Request A, 5 seconds Request B, 6 seconds Request C, 7 seconds However, the result is like this Request A, 5 seconds Request B, 10 seconds Request C, 15 seconds This have to mean that the requests are queued and not run simultaneously, right? Isnt this opposite to what async is? I also tried to add a random get-parameter to the url in order to force some uniqueness to the request, no luck though. I did read a little about this. If you avoid using the same "request object (?)" this problem wont occure. Is it possible to force this behaviour in JQuery? This is the code that I am using $.ajax( { url : strAjaxUrl + '?random=' + Math.floor(Math.random()*9999999999), data : 'ajax=add-to-cart&product=' + product, type : 'GET', success : function(responseData) { // update ui }, error : function(responseData) { // show error } }); I also tried both GET and POST, no difference. I want the requests to be sent right when the button is clicked, not when the previous request is finnished. I want the requests to be run simultaneously, not in a queue.

  • Update parameter not working on bound DropDownList

    - by ProfK
    I have a DropDownList declared like this: <asp:DropDownList ID="campaignTypeList" runat="server" Width="150px" DataTextField="Name" DataValueField="CampaignTypeId" DataSourceID="campaignTypesDataSource" SelectedValue='<%# Bind("CampaignTypeID") %>'> </asp:DropDownList> Using the designer, my SqlDataSource is configured as follows1: <asp:SqlDataSource ID="campaignDataSource" runat="server" ConflictDetection="CompareAllValues" ConnectionString="<%$ ConnectionStrings:ProVantageMediaManagement %>" SelectCommand="ActivationCampaignGetById" SelectCommandType="StoredProcedure" UpdateCommand="ActivationCampaignUpdate" UpdateCommandType="StoredProcedure"> <SelectParameters> <asp:QueryStringParameter DefaultValue="98" Name="campaignId" Direction="Input" QueryStringField="id" Type="Int32" /> </SelectParameters> <UpdateParameters> <asp:QueryStringParameter DefaultValue="98" Name="campaignId" Direction="Input" QueryStringField="id" Type="Int32" /> <asp:Parameter Name="campaignName" Type="String" /> <asp:Parameter Name="campaignTypeId" Type="Int32" /> </UpdateParameters> </asp:SqlDataSource> Yet when the update command is sent to the DB, the campaignTypeId value is always 1, no matter which item is selected in the DropDownList. What am I doing wrong? 1 Bonus points for telling us what a ControlParameter is meant for, if not for handling values of controls in a scenario like this.

  • What setting needs to be made to make .Net Automation responsive?

    - by Greg
    Have an app that is looking for application windows being created on the desktop using class Unresponsive { private StructureChangedEventHandler m_UIAeventHandler = new StructureChangedEventHandler(OnStructureChanged); public Unresponsive() { Automation.AddStructureChangedEventHandler(AutomationElement.RootElement, TreeScope.Children, m_UIAeventHandler); } private void OnStructureChanged(object sender, StructureChangedEventArgs e) { Debug.WriteLine("Change event"); } } You can see the same issue using UISpy.exe, selecting the desktop and configuring scope for children and just the structure changed event. The problem I'm trying to resolve is that the events are not raised in a timely manner, there seems to be some grouping/delay which makes the app appear to be non responsive. If you start a new app with 1 window and wait a second you get the event, seems alright. If you start the same app several times without delay (say clicking on quickstart), it's not until all of the instances of the app get 'initialised' by the AutomationProxies that you get the notice for the first app (and in short order the other apps/windows). I've sat watching task manager as each instance of the app starts to grow as it is initialised, waiting until the last app is done and then seeing the events all come in. Similarly any time any apps are starting windows within a timeframe there seems to be some blocking. I can't see how to configure this timeframe, or get each structure changed event to be sent on as soon as it happens. Also, this process of listening for structure changed events seems to be leaking, just by listening there is a leak in native memory. (visible in UISpy and my app)

  • Message driven bean not responding until client method is complete

    - by poijoi
    Hi, I have a MDB deployed on Jboss 4.2.2 and a client on the same server that produces messages and expects a reply from the MDB via a temporary queue created before the message is sent. When I run the client, I see that it creates the message, puts it in the queue and waits for the reply (no problem so far) ... but when I check in the logs I see that the timeout is reached and no response is received. When the timeout occurs and the client's method is complete the MDB starts processing the message that should have been processed the moment the client put it in the queue. As a consequence of this timing issue, when the MDB tries to reply to the temp queue, it fails since the client is already gone. If I run the same client from a remote server, I have no problem... The MDB picks up the message from the queue right away and the client receives its response right after the processing is complete. I'm using container managed transactions. I suspect it has something to do with that... I think the client's "send message/receive reply" might be all be considered a transaction before it commits to put the message in the queue... but I'm not sure if this is correct. If this is the case, why did I not see the same behavior from the remote client? is client managed transaction the default setting and that's what my remote server was using? Any idea how to fix this? Thanks in advance! PJ

  • Problems running XNA game on 64-bit Windows 7

    - by Tesserex
    I'm having problems getting my game engine to run on my brother's machine, which is running 64-bit Windows 7. I'm developing on 32-bit XP SP2. My app uses XNA, FMOD.NET, and another dll I wrote entirely in C#. Everything is targeted to x86, not AnyCPU. I've read that this is required for XNA to work because there is no 64-bit xna framework. I recompiled FMOD.NET as x86 as well and made sure to be using the 32-bit version of the native dll. So I don't see any problems there. However when he tries to run my app, it gives an error which is mysterious, but not unheard of. A FileNotFoundException with an empty file name, and the top of the stack trace is in my main form constructor. The message is The specified module could not be found. (Exception from HRESULT: 0x8007007E) I found some threads online about this error, all with very vague, mixed, and fuzzy responses that don't really help me. Most remind people to target x86. Some say check that they have all the dlls necessary. I gave my brother Microsoft.Xna.Framework.dll, but does he need to install the entire XNA redistributable package? When I take everything I sent him and stick it in a random directory, it still runs fine for me. I developed the game in VS2008, not in game studio, using XNA 3.0 and a Windows Forms control that uses XNA drawing which I found in an msdn tutorial. I would also like to avoid requiring a full installer if possible. Any insight? Please?

  • Using SetParent to steal the main window of another process but keeping the message loops separate

    - by insta
    Background: My coworker and I are maintaining a million-line legacy application we inherited. Its frontend is written in VB6, and as we're devoting almost all of our resources to converting it to C#, we are looking for quick & dirty solutions to our specific problem. The application behaves in a plugin-ish manner. There are up to 20ish separate ActiveX controls that can be loaded at once in a grid-style layout. The problem is that the ActiveX controls do all of their processing on their own UI thread, and as a lot of it is blocking waiting on network access, the UI gets very soupy. When our hosting C# app loads these controls, it becomes unresponsive because of how many controls are chewing up UI resources doing nothing. To top it off, the controls are fragile and will crash at the slightest provocation. When they are hosted in the main C# app, it creates serious instability. The best my coworker and I have come up with so far is starting a process per ActiveX control. This process, which we call the proxy, is another winforms app. It uses named pipes to communicate with the hosting process. The hosting process creates a window, loads an ActiveX control of our choice (via some reflections & AxHost magic), and tells the main process what its window handle is via the named pipe. The main process uses a combination of SetParent, and SetWindowPos to move the proxy application into itself to emulate a plugin. Size updates are sent via the named pipe. This works well enough until the ActiveX application does some sort of lengthy process and we click around on the main window while it's working. For awhile the main window is responsive, but eventually it becomes unresponsive as the child window waits for its UI thread. How can we keep the child windows on their own complete thread while still getting the benefits of SetParent? (please let me know if anything isn't clear!)

  • How do you parse with SAX using Attributes & Values to a URL path using iPhone SDK?

    - by Jim
    I'm trying to get my head around parsing with SAX and thought a good place to start was the TopSongs example found at the iPhone Dev Center. I get most of it but when it comes to reaching Attributes and Values within a node I can't find a good example anywhere. The XML has a path to a URL for the coverArt. And the XML node looks like this. <itms:coverArt height="60" width="60">http://a1.phobos.apple.com/us/r1000/026/Music/aa/aa/27/mzi.pbxnbfvw.60x60-50.jpg</itms:coverArt> What I've tried is this for the startElement… ((prefix != NULL && !strncmp((const char *)prefix, kName_Itms, kLength_Itms)) && (!strncmp((const char *)localname, kName_CoverArt, kLength_Item) && !strncmp((const char *)attributes, kAttributeName_CoverArt, kAttributeLength_CoverArt) && !strncmp((const char *)attributes, kValueName_CoverArt, kValueLength_CoverArt) || !strncmp((const char *)localname, kName_Artist, kLength_Artist) || and picking it up again with just the localname at the end like this. if (!strncmp((const char *)localname, kName_CoverArt, kLength_CoverArt)) { importer.currentSong.coverArt = [NSURL URLWithString:importer.currentString]; The trace is -[Song setCoverArt:]: unrecognized selector sent to instance.

  • Several Objective-C objects become Invalid for no reason, sometimes.

    - by farnsworth
    - (void)loadLocations { NSString *url = @"<URL to a text file>"; NSStringEncoding enc = NSUTF8StringEncoding; NSString *locationString = [[NSString alloc] initWithContentsOfURL:[NSURL URLWithString:url] usedEncoding:&enc error:nil]; NSArray *lines = [locationString componentsSeparatedByString:@"\n"]; for (int i=0; i<[lines count]; i++) { NSString *line = [lines objectAtIndex:i]; NSArray *components = [line componentsSeparatedByString:@", "]; Restaurant *res = [byID objectForKey:[components objectAtIndex:0]]; if (res) { NSString *resAddress = [components objectAtIndex:3]; NSArray *loc = [NSArray arrayWithObjects:[components objectAtIndex:1], [components objectAtIndex:2]]; [res.locationCoords setObject:loc forKey:resAddress]; } else { NSLog([[components objectAtIndex:0] stringByAppendingString:@" res id not found."]); } } } There are a few weird things happening here. First, at the two lines where the NSArray lines is used, this message is printed to the console- *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSCFDictionary count]: method sent to an uninitialized mutable dictionary object' which is strange since lines is definitely not an NSMutableDictionary, definitely is initialized, and because the app doesn't crash. Also, at random points in the loop, all of the variables that the debugger can see will become Invalid. Local variables, property variables, everything. Then after a couple lines they will go back to their original values. setObject:forKey never has an effect on res.locationCoords, which is an NSMutableDictionary. I'm sure that res, res.locationCoords, and byId are initialized. I also tried adding a retain or copy to lines, same thing. I'm sure there's a basic memory management principle I'm missing here but I'm at a loss.

  • How to convert Unicode strings (\u00e2, etc) into NSString for display?

    - by karlbecker_com
    I am trying to support arbitrary unicode from a variety of international users. They have already put a bunch of data into sqlite databases on their iPhones, and now I want to capture the data into a database, then send it back to their device. Right now I am using a php page that is sending data back to from an internet mysql database. The data is saved in the mysql database properly, but when it's sent back it comes out as unicode text, such as Frank\u00e2\u0080\u0099s iPad instead of just Frank's iPad where the apostrophe should really be a curly apostrophe. The answer posted to another question indicates that there is no built-in Cocoa methods to convert the "\u00e2\u0080\u0099" portion of the unicode string from the webserver to an NSString object. Is this correct? That seems really surprising (and scarily disappointing), since Cocoa definitely allows input from many different Unicode characters, and I need to support any arbitrary language that I have never heard of, and all of the possible characters. I save them to and from the local sqlite database just fine now, but once I send it to a web server, then perhaps pull down different data, I want to ensure the data pulled from the web server is correctly formatted.

  • Validating age field

    - by Marcelo
    Hi people, I'm trying to validate an age field in a form but I'm having some problem. First I tried to make sure that the field will not be send empty. I don't know JavaScript so I searched some scripts and adapted them to this: function isInteger (s) { var i; if (isEmpty(s)) if (isInteger.arguments.length == 1) return 0; else return (isInteger.arguments[1] == true); for (i = 0; i < s.length; i++) { var c = s.charAt(i); if (!isDigit(c)) return false; } return true; } function isEmpty(s) { return ((s == null) || (s.length == 0)) } function validate_required(field,alerttxt) { with (field) { if (value==null||value=="") { alert(alerttxt);return false; } else { return true; } } } function validate_form(thisform) { with (thisform) { if ((validate_required(age,"Age must be filled out!")==false) || isInteger(age,"Age must be and int number")==false)) {email.focus();return false;} } } //html part <form action="doador.php" onsubmit="return validate_form(this)" method="post"> It's working fine for empty fields, but if I type any letters or characters in age field, it'll be sent and saved a 0 in my database. Can anyone help me? Sorry for any mistake in English, and thanks in anvance for your help.

  • Flash doesn't connect to socket even though policy allows it

    - by Bart van Heukelom
    In my Flash app, I'm connecting to my server like this: Security.loadPolicyFile("xmlsocket://example.com:12860"); socket = new Socket("example.com", 12869); socket.writeByte(...); ... socket.flush(); At port 12860 I'm running a socket policy server, which (according to this document) correctly serves up my policy like this: 00000000 3c 70 6f 6c 69 63 79 2d 66 69 6c 65 2d 72 65 71 <policy- file-req 00000010 75 65 73 74 2f 3e 00 uest/>. 00000000 3c 63 72 6f 73 73 2d 64 6f 6d 61 69 6e 2d 70 6f <cross-d omain-po 00000010 6c 69 63 79 3e 3c 73 69 74 65 2d 63 6f 6e 74 72 licy><si te-contr 00000020 6f 6c 20 70 65 72 6d 69 74 74 65 64 2d 63 72 6f ol permi tted-cro 00000030 73 73 2d 64 6f 6d 61 69 6e 2d 70 6f 6c 69 63 69 ss-domai n-polici 00000040 65 73 3d 22 6d 61 73 74 65 72 2d 6f 6e 6c 79 22 es="mast er-only" 00000050 20 2f 3e 3c 61 6c 6c 6f 77 2d 61 63 63 65 73 73 /><allo w-access 00000060 2d 66 72 6f 6d 20 64 6f 6d 61 69 6e 3d 22 2a 22 -from do main="*" 00000070 20 74 6f 2d 70 6f 72 74 73 3d 22 31 32 38 36 39 to-port s="12869 00000080 22 20 2f 3e 3c 2f 63 72 6f 73 73 2d 64 6f 6d 61 " /></cr oss-doma 00000090 69 6e 2d 70 6f 6c 69 63 79 3e 00 in-polic y>. I get no security warnings, which I used to get before the policy server was in place. Still, the connection to port 12869 doesn't work. It's made (I can see with Wireshark and on the server), but no data is sent by Flash. It might be worth knowing that the SWF itself is served from example.com as well.

  • Inner join on 2 arrays?

    - by russ
    I'm trying to find a solution to the following (I'm thinking with Linq) to the following: I need to pull down certain files from a larger list of files on an ftp server that have a similar file name. For example, we send an order file to some company for processing then they return a response file that we can download. So, I could send them the files "order_123.txt" and "order_456.txt". After a certain amount of time I need to go look for and download the responses for those files that will be named "order_123.resp" and "order_456.resp". The kicker is that in some cases I can have multiple responses in which case they would create "order_123-1.resp" and "order_123-2.resp" and also the files don't get removed from the server. I know this can be accomplished by looping through the files I know I need responses to then loop through all the files on the server until I find files that match but I'm hoping that I don't have to loop through the files on the server more than once. This example may help clarify: I've sent "order_222.txt" and "order_333.txt" they processed them and the ftp server contains: "order_111-1.resp" "order_001.resp" "order_222-1.resp" "order_222-2.resp" "order_333.resp" I need to download the 3rd, 4th, and 5th file. Thanks.
