• Implementation of MVC with SQLite and NSURLConnection, use cases?

  - by user324723

  I'm interested in knowing how others have implemented/designed database & web services in their iphone app and how they simplified it for the entire application. My application is dependent on these services and I can't figure out a efficient way to use them together due to the (semi)complexity of my requirements. My past attempts on combining them haven't been completely successful or at least optimal in my mind. I'm building a database driven iphone app that uses a relational database in sqlite and consumes web services based on missing content or user interaction. Like this hasn't been done before...right? Since I am using a relational database - any web services consumed requires normalization, parsing the result and persisting it to the database before it can be displayed in a table view controller. The applications UI consists of nested(nav controller) table views where a user can select a cell and be taken to the next table view where it attempts to populate the table views data source from the database. If nothing exists in the database then it will send a request via web services to download its content, thus download - parse - persist - query - display. Since the user has the ability to request a refresh of this data it still requires the same process. Quickly describing what I've implemented and tried to run with - 1st attempt - Used a singleton web service class that handled sending web service requests, parsing the result and returning it to the table view controller via delegate protocols. Once the controller received that data it would then be responsible for persisting it to the database and re-returning the result. I didn't like the idea of only preventing the case where the app delegate selector doesn't exists(released) causing the app to crash. 2nd attempt - Used NSNotificationCenter for easy access to both database and web services but later realized it was more complex due to adding and removing observers per view(which isn't advised anyways).

• Gdata JavaScript Authsub continues redirect

  - by Krustal

  I am using the JavaScript Google Data API and having issues getting the AuthSub script to work correctly. This is my script currently: google.load('gdata', '1'); function getCookie(c_name){ if(document.cookie.length>0){ c_start=document.cookie.indexOf(c_name + "="); if(c_start!=-1){ c_start=c_start + c_name.length+1; c_end=document.cookie.indexOf(";",c_start); if(c_end==-1) c_end=document.cookie.length; return unescape(document.cookie.substring(c_start, c_end)); } } return ""; } function main(){ var scope = 'http://www.google.com/calendar/feeds/'; if(!google.accounts.user.checkLogin(scope)){ google.accounts.user.login(); } else { /* * Retrieve all calendars */ // Create the calendar service object var calendarService = new google.gdata.calendar.CalendarService('GoogleInc-jsguide-1.0'); // The default "allcalendars" feed is used to retrieve a list of all // calendars (primary, secondary and subscribed) of the logged-in user var feedUri = 'http://www.google.com/calendar/feeds/default/allcalendars/full'; // The callback method that will be called when getAllCalendarsFeed() returns feed data var callback = function(result) { // Obtain the array of CalendarEntry var entries = result.feed.entry; //for (var i = 0; i < entries.length; i++) { var calendarEntry = entries[0]; var calendarTitle = calendarEntry.getTitle().getText(); alert('Calendar title = ' + calendarTitle); //} } // Error handler to be invoked when getAllCalendarsFeed() produces an error var handleError = function(error) { alert(error); } // Submit the request using the calendar service object calendarService.getAllCalendarsFeed(feedUri, callback, handleError); } } google.setOnLoadCallback(main); However when I run this the page redirects me to the authentication page. After I authenticate it send me back to my page and then quickly sends me back to the authenticate page again. I've included alerts to check if the token is being set and it doesn't seem to be working. Has anyone has this problem?

• mysql image disable print download

  - by Vish

  Hi, We use a Flex AIR client and a WAMP server. Tiff images are stored in MySQL. Currently, I can download the image from AIR client and it prompts for a download dialog. Things are fine till this point. We got a new requirement. Requirement is that only some users can print the image which gets downloaded. For other users, they should not be able to print the tiff image. Wondering how to accomplish this. One idea, not sure if its efficient, is to convert the image requested to pdf at the server side, disable print option there(hope there are API's available) and send back the pdf. Please let me know btter ideas. Also, is there a way to prevent file download dialog from popping up everytime the file is requested for download? Can we just get the file stream to the client and manipulate it to open with a particular viewer or write it to pdf... Please help.

• Credit Card storage solution

  - by jtnire

  Hi Everyone, I'm developing a solution that is designed to store membership details, as well as credit card details. I'm trying to comply with PCI DSS as much as I can. Here is my design so far: PAN = Primary account number == long number on credit card Server A is a remote server. It stores all membership details (Names, Address etc..) and provides indivudal Key A's for each PAN stored Server B is a local server, and actually holds the encrypted PANs, as well as Key B, and does the decryption. To get a PAN, the client has to authenticate with BOTH servers, ask Server A for the respective Key A, then give Key A to server B, which will return the PAN to the client (provided authentication was sucessful). Server A will only ever encrypt Key A with Server B's public Key, as it will have it beforehand. Server B will probably have to send a salt first though, however I doin't think that has to be encrypted I havn't really thought about any implementation (i.e. coding) specifics yet regarding the above, however the solution is using Java's Cajo framework (wrapper for RMI) so that is how the servers will communicate with each other (Currently, membership details are transfered in this way). The reason why I want Server B to do the decryption, and not the client, is that I am afraid of decryption keys going into the client's RAM, even though it's probably just as bad on the server... Can anyone see anything wrong with the above design? It doesn't matter if the above has to be changed. Thanks jtnire

• Cryptic Erlang Errors

  - by Jim

  Okay so I started learning erlang recently but am baffled by the errors it keeps returning. I made a bunch of changes but I keep getting errors. The syntax is correct as far as I can tell but clearly I'm doing something wrong. Have a look... -module(pidprint). -export([start/0]). dostuff([]) - receive begin - io:format("~p~n", [This is a Success]) end. sender([N]) - N ! begin, io:format("~p~n", [N]). start() - StuffPid = spawn(pidprint, dostuff, []), spawn(pidprint, sender, [StuffPid]). Basically I want to compile the script, call start, spawn the "dostuff" process, pass its process identifier to the "sender" process, which then prints it out. Finally I want to send a the atom "begin" to the "dostuff" process using the process identifier initially passed into sender when I spawned it. The errors I keep getting occur when I try to use c() to compile the script. Here they are.. ./pidprint.erl:6: syntax error before: '-' ./pidprint.erl:11: syntax error before: ',' What am I doing wrong?

• In App Purchase Unique Identifying Data

  - by dageshi

  O.K so I'm writing a iPhone travel guide, you purchase a subscription to a travel guide for 3 months, it downloads a fairly hefty database and for 3 months that database gets updated weekly with new stuff. Now what I'd like to do is make the user enter their email address as a one off action before they purchase their first guide, for China say. The purpose for doing this is 1) To allow me to contact the user by email when they add a note/tip for a particular place (the app will allow them to send notes & information to me) 2) To Uniquely identify who has purchased the subscription so that if they wipe their device and reinstall the app they can plug the email address in and pickup their subscriptions again. Or so they can use the same subscription on another device they own. My concerns are 1) Will Apple allow the email method of restoring functionality to a second or restored device? 2) As long as I tell the user what I'm using their email address for (aka I won't sell it to anyone else and use it for X purposes) will it be o.k to ask for said email address? And as a side note, can I tack the devices unique id onto my server comms to track devices or is apple going to through a hissy fit about that as well?

• Connecting to an RMI object without registry

  - by Mark Probst

  I think I need to connect to a remote RMI object without going through the registry, but I don't know how. My situation is this: I'm implementing a simple job distribution service which consists of one distributor and multiple workers. The distributor has a registered RMI object to which clients connect to send jobs, and workers connect to accept jobs. Unfortunately the distributor and worker hosts are behind a firewall. To get to the distributor host I am tunneling two ports (one for the registry, one for the distributor object) via SSH, so I can get to the registry and the distributor from outside the firewall. To make that work I have to set "-Djava.rmi.server.hostname=localhost" on the distributor JVM so that the clients connect to their local, tunneled port, instead of the port on the actual distributor host, which is blocked. This creates a problem for the workers, though, because they need to connect to the distributor directly, but because of the "localhost" redirection they behave like clients and try to connect to a port on their own host, which is not available, because I'm not tunneling on the workers (it is impractical). Now, if I could connect to a remote object directly by giving the hostname and port, I could do away both with the registry on the distributor and the "localhost" hack, and make the workers connect properly. How do I do that? Or is there a different solution to this problem?

• Keeping sync in multiplayer RTS game that uses floating point arithmetic

  - by Calmarius

  I'm writing a 2D space RTS game in C#. Single player works. Now I want to add some multiplayer functionality. I googled for it and it seems there is only one way to have thousands of units continuously moving without a powerful net connection: send only the commands through the network while running the same simulation at every player. And now there is a problem the entire engine uses doubles everywhere. And floating point calculations are depends heavily on compiler optimalizations and cpu architecture so it is very hard to keep things syncronized. And it is not grid based at all, and have a simple phisics engine to move the space-ships (space ships have impulse and angular-momentum...). So recoding the entire stuff to use fixed point would be quite cumbersome (but probably the only solution). So I have 2 options so far: Say bye to the current code and restart from scratch using integers Make the game LAN only where there is enough bandwidth to have 8 players with thousands of units and sending the positions and orientation etc in (almost) every frame... So I looking for better opinions, (or even tips on migrating the code to fixed-point without messing everything up...)

• Facebook: Social Widgets versus Share

  - by just_wes

  Hello all, I am interested in people's thoughts on Facebook's new social widgets thing. Most notably the new "Like" button. The concept I am struggling with is the difference between "Like" and "Share". I have an existing Connect application. This application has its own fan page on Facebook. People can become "Fans" of the page and register to receive email updates and the like. The application is currently programmed to update its own fan page any time content is added to the site. Enter Social Widgets and "Like". People who visit our site can currently "share" our content on Facebook. With "Share" they can post a full item to their wall with a comment or send the content item as a message to another Facebook user. "Like" seems to do the same thing minus the message part. However "Like" automatically subscribes people to the fan page. My question is simply, should I add "Like" to my existing Connect site? Is "Like" different than what I already have? Are Social Widgets the future of Connect? Thanks!

  hi I am working a client/server application in C#. My server Capture current Mouse Cursors and send these to client so that Cursor of the cleint also chage accordingly.I can detect windows Cursors and serialize them over binaryformatter. it works fine but but problem is there are many cursors that can not be detected like mspaint cursors so i have to take its handler and create the cursor and its x nad y hotspots and add them in an arraylist and serialize it over network but after 10 to 15 minute it thorws exception "Error HRESULT E_FAIL has been returned from a call to a COM Compeonet" and cleint throws the exception of "method of invocation" Can anybody guid me what going wrong ort some better way to do like this Some code is here IntPtr curInfo = GetCurrentCursor(); Cursor cur; Icon ic; byte cursor = 0; if (curInfo != null && curInfo.ToInt32() != 0) { cur = CheckForCusrors(curInfo); try { if (!isLinuxClient) { if (cur == null) { PlatformInvokeUSER32.GetIconInfo(curInfo, out temp); ic = Icon.FromHandle(curInfo); //bitmap = ic.ToBitmap(); ArrayList ar = new ArrayList(); ar.Add(ic); ar.Add(temp.xHotspot); ar.Add(temp.yHotspot); b.Serialize(stm, ar); } else { ArrayList ar = new ArrayList(); ar.Add(cur); b.Serialize(stm, ar); } } public Cursor CheckForCusrors(IntPtr hCur) { if (hCur == Cursors.AppStarting.Handle) return Cursors.AppStarting; else if (hCur == Cursors.Arrow.Handle) return Cursors.Arrow; . . . else if (hCur == Cursors.PanWest.Handle) return Cursors.PanWest; return null; } `

• Javascript + PHP $_POST array empty

  - by Peterim

  While trying to send a POST request via xmlhttp.open("POST", "url", true) (javascript) to the server I get an empty $_POST array. Firebug shows that the data is being sent. Here is the data string from Firebug: a=1&q=151a45a150.... But $_POST['q'] returns nothing. The interesting thing is that file_get_contents('php://input') does have my data (the string above), but PHP somehow doesn't recognize it. Tried both $_POST and $_REQUEST, nothing works. Headers being sent: POST /test.php HTTP/1.1 Host: website.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-us;q=0.7,en;q=0.3 Accept-Encoding: gzip,deflate Accept-Charset: utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Referer: http://website.com/ Content-Length: 156 Content-Type: text/plain; charset=UTF-8 Pragma: no-cache Cache-Control: no-cache Thank you for any suggestions.

• Help a CRUD programmer think about an "approval workflow"

  - by gerdemb

  I've been working on a web application that is basically a CRUD application (Create, Read, Update, Delete). Recently, I've started working on what I'm calling an "approval workflow". Basically, a request is generated for a material and then sent for approval to a manager. Depending on what is requested, different people need to approve the request or perhaps send it back to the requester for modification. The approvers need to keep track of what to approve what has been approved and the requesters need to see the status of their requests. As a "CRUD" developer, I'm having a hard-time wrapping my head around how to design this. What database tables should I have? How do I keep track of the state of the request? How should I notify users of actions that have happened to their requests? Is their a design pattern that could help me with this? Should I be drawing state-machines in my code? I think this is a generic programing question, but if it makes any difference I'm using Django with MySQL.

• Ruby and public_method_defined? : strange behaviour

  - by aXon

  Hi there Whilst reading through the book "The well grounded Rubyist", I came across some strange behaviour. The idea behind the code is using one's own method_missing method. The only thing I am not able to grasp is, why this code gets executed, as I do not have any Person.all_with_* class methods defined, which in turn means that the self.public_method_defined?(attr) returns true (attr is friends and then hobbies). #!/usr/bin/env ruby1.9 class Person PEOPLE = [] attr_reader :name, :hobbies, :friends def initialize(mame) @name = name @hobbies = [] @friends = [] PEOPLE << self end def has_hobby(hobby) @hobbies << hobby end def has_friend(friend) @friends << friend end def self.method_missing(m,*args) method = m.to_s if method.start_with?("all_with_") attr = method[9..-1] if self.public_method_defined?(attr) PEOPLE.find_all do |person| person.send(attr).include?(args[0]) end else raise ArgumentError, "Can't find #{attr}" end else super end end end j = Person.new("John") p = Person.new("Paul") g = Person.new("George") r = Person.new("Ringo") j.has_friend(p) j.has_friend(g) g.has_friend(p) r.has_hobby("rings") Person.all_with_friends(p).each do |person| puts "#{person.name} is friends with #{p.name}" end Person.all_with_hobbies("rings").each do |person| puts "#{person.name} is into rings" end The output is is friends with is friends with is into rings which is really understandable, as there is nothing to be executed.

• Dynamically invoke web service at runtime

  - by Ulrik Rasmussen

  So, our application needs support for dynamically calling web services which are unknown at compile time. The user should therefore be able to specify a URL to a WSDL, and specify some data bindings for the request and reply parameters. When Googling for answers, it seems like the way to do this is by actually compiling a web service proxy class at runtime, loading it, and invoking the methods using reflection. I think this seems like a rather clunky approach, given that I don't really need a strongly typed set of classes when I'm going to cast my data dynamically anyway. Dynamically compiling code for doing something that simple also just seems like The Wrong Way To Do It. Restricting ourself to the SOAP protocol, is there any library for C# that implements this protocol for dynamic use? I can imagine that it would be possible to generate runtime key/value data structures from the WSDL, which could be used to specify the request messages, as well as reading the replies. The library should then be able to send well-formed SOAP messages to the server, and parse the replies, without the programmer having to generate the XML manually (at least not the headers and other plumbing). I can't seem to find any library that actually does this. Is what I want to do really that esoteric, or have I just searched the wrong places? Thanks, Ulrik

• How to implement an ID field on a POCO representing an Identity field in SQL Server?

  - by Dr. Zim

  If I have a Domain Model that has an ID that maps to a SQL Server identity column, what does the POCO look like that contains that field? Candidate 1: Allows anyone to set and get the ID. I don't think we want anyone setting the ID except the Repository, from the SQL table. public class Thing { public int ID {get;set;} } Candidate 2: Allows someone to set the ID upon creation, but we won't know the ID until after we create the object (factory creates a blank Thing object where ID = 0 until we persist it). How would we set the ID after persisting? public class Thing { public Thing () : This (ID: 0) {} public Thing (int ID) { this.ID = ID } private int _ID; public int ID { get { return this.ID;}; } Candidate 3: Methods to set ID? Somehow we would need to allow the Repository to set the ID without allowing the consumer to change it. Any ideas? Is this barking up the wrong tree? Do we send the object to the Repository, save it, throw it away, then create a new object from the loaded version and return that as a new object?

• SSRS 2008 - Sending report as email

  Hi all, What I want to do is render a SSRS 2008 report as HTML (actually MHTML) and send that as the body in an email. Has anyone done this? I've almost got it (I think) but I seem to have a encoding problem. The email shows up as what looks like some sort of base64 encoding. Like this: MIME-Version: 1.0 Content-Type: multipart/related; boundary="----=_NextPart_01C35DB7.4B204430" X-MSSQLRS-ProducerVersion: V10.0.2531.0 This is a multi-part message in MIME format. ------=_NextPart_01C35DB7.4B204430 Content-ID: Content-Disposition: inline; filename="FollowUpNotification" Content-Type: text/html; name="FollowUpNotification"; charset="utf-8" Content-Transfer-Encoding: base64 PCFET0NUWVBFIEhUTUwgUFVCTElDICItLy9XM0MvL0RURCBIVE1MIDQuMDEgVHJhbnNp...

• Setting acquired location to a text view: How to maintain?

  - by Mark

  Hi, I have built an app for the Motorola Droid which should automatically update a server with the phone's location. After the user performs a particular task on the main activity screen, an alarm is set to update the user's location periodically, using a service. The alarm is explicitly stopped when the user completes another task. Thing is, I have set up a location manager within the main activity's onCreate() method which is supposed to place the first acquired lat/long into two textview fields. Even though the manifest is set up for acquiring coarse and fine coords and I'm using requestLocationUpdates (String provider, long minTime, float minDistance, LocationListener listener), with minTime and minDistance set to zero, I'm not seeing the coords coming up on the screen. With that, I'm not recording any locations on the server. When I seed the textviews with sample coords, they are being recorded fine on the server. I am not at a computer that can run the IDE, so don't currently have the code, but am desperate for some help on this. One other thing is that the main activity screen calls a photography app before the user manually clicks "send data". I'm suspicious that I may need to override the main activity's onResume() method to do this location acquisition. Please help, thanks. Mark.

• SystemStackError in Rails::ActiveSupport::Callbacks

  - by coreyward

  I'm building a Rails app that connects to Dropbox and syncs with a folder to update a personal site. I'm using Rails 3.0.3, Ruby 1.9.2, and the Dropbox gem. Right now I have a DropboxAccounts Controller, and two models: DropboxSession, which wraps calls to the gem with application-specific functionality, and DropboxAccount, which stores the session and settings in the database. After the user authorizes their account with Dropbox they're redirected back over and the DropboxAccount is saved with the authorized session. That all works just fine. My problem is that when I try to call Dropbox::API#create_folder(any path) I end up with a SystemStackError in lib/activesupport/callbacks.rb:421 which refers to the code below. If I remove the call to create the folder, it works. If I call create folder from another request, it works. I doubled the stack size to 16K to no avail. # This is called the first time a callback is called with a particular # key. It creates a new callback method for the key, calculating # which callbacks can be omitted because of per_key conditions. # def __create_keyed_callback(name, kind, object, &blk) #:nodoc: @_keyed_callbacks ||= {} @_keyed_callbacks[name] ||= begin str = send("_#{kind}_callbacks").compile(name, object) class_eval <<-RUBY_EVAL, __FILE__, __LINE__ + 1 def #{name}() #{str} end # THIS IS LINE 421 protected :#{name} RUBY_EVAL true end end I'm not very familiar with Rails yet, and I'm not sure what the intention of the code above is or why it would cause a stack overflow. I'm not using any method_missing/ghost method magic in my code. I suspected it was something with a callback serialize :files but commenting it out did nothing. My DropboxAccount model contains only a call to belongs_to :user, and DropboxSession is just a handful of methods, none of which contain callbacks. Bypassing them and using the Dropbox::Session methods directly doesn't help. I hope someone on StackOverflow can help me with this stack overflow. ;)

• How to establish a socket connection from iPhone to a Apache server and communicate via PHP?

  - by candoyo

  Hi, I am working on an iPhone game which is depended on a LAMP server. I want to create a "event" based system where the apache server sends an event to the iphone. For this, I am thinking of using "CFStreamCreatePairWithSocketToHost" to connect to port 80 of the apache server. I am able to successfully connect to the server and open a read and write stream via the iPhone, but I am not sure how to send data to the iphone using PHP running from the LAMP server to the iPhone. I think I can use fsockopen in php to open a socket connection and write data to that socket. I tired running this code $fp = fsockopen("tcp://localhost", 80, $errno, $errstr); if (!$fp) { echo "ERROR: $errno - $errstr<br />\n"; } else { echo"writing to socket "; fwrite($fp, "wwqeqweqw eqwe qwe \n"); //echo fread($fp, 26); fclose($fp); echo "done"; } But, I dont see anything being read on the iphone.. Any idea what's going on, or how to accomplish this? Thanks!

• NSDrawer delegate pointing to deallocated object?

  - by Isaac

  A user has sent in a crash report with the stack trace listed below (I have not been able to reproduce the crash myself, but every other crash this user has reported has been a valid bug, even when I couldn't reproduce the effect). The application is a reference-counted Objective-C/Cocoa app. If I am interpreting it correctly, the crash is caused by attempting to send a drawerDidOpen: message to a deallocated object. The only object that should be receiving drawerDidOpen: is the drawer's delegate object (nowhere does any object register to receive drawer notifications), and the drawer's delegate object is instantiated via the XIB/NIB file, wired to the delegate outlet of the drawer, and not referenced anywhere else. Given that, how can I protect against the delegate getting dealloc'd before the drawer notification? Or, alternately, what have I misinterpreted that might be causing the crash? Crash log/stack trace: Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x0000000000000010 Crashed Thread: 0 Dispatch queue: com.apple.main-thread Application Specific Information: objc_msgSend() selector name: drawerDidOpen: Thread 0 Crashed: Dispatch queue: com.apple.main-thread 0 libobjc.A.dylib 0x00007fff8272011c objc_msgSend + 40 1 com.apple.Foundation 0x00007fff87d0786e _nsnote_callback + 167 2 com.apple.CoreFoundation 0x00007fff831bcaea __CFXNotificationPost + 954 3 com.apple.CoreFoundation 0x00007fff831a9098 _CFXNotificationPostNotification + 200 4 com.apple.Foundation 0x00007fff87cfe7d8 -[NSNotificationCenter postNotificationName:object:userInfo:] + 101 5 com.apple.AppKit 0x00007fff8512e944 _NSDrawerObserverCallBack + 840 6 com.apple.CoreFoundation 0x00007fff831d40d7 __CFRunLoopDoObservers + 519 7 com.apple.CoreFoundation 0x00007fff831af8c4 CFRunLoopRunSpecific + 548 8 com.apple.HIToolbox 0x00007fff839b8ada RunCurrentEventLoopInMode + 333 9 com.apple.HIToolbox 0x00007fff839b883d ReceiveNextEventCommon + 148 10 com.apple.HIToolbox 0x00007fff839b8798 BlockUntilNextEventMatchingListInMode + 59 11 com.apple.AppKit 0x00007fff84de8a2a _DPSNextEvent + 708 12 com.apple.AppKit 0x00007fff84de8379 -[NSApplication nextEventMatchingMask:untilDate:inMode:dequeue:] + 155 13 com.apple.AppKit 0x00007fff84dae05b -[NSApplication run] + 395 14 com.apple.AppKit 0x00007fff84da6d7c NSApplicationMain + 364 15 (my app's identifier) 0x0000000100001188 start + 52

• SQL Server stored procedure return code oddity

  - by gbn

  Hello The client that calls this code is restricted and can only deal with return codes from stored procs. So, we modified our usual contract to RETURN -1 on error and default to RETURN 0 if no error If the code hits the inner catch block, then the RETURN code default to -4. Where does this come from, does anyone know...? IF OBJECT_ID('dbo.foo') IS NOT NULL DROP TABLE dbo.foo GO CREATE TABLE dbo.foo ( KeyCol char(12) NOT NULL, ValueCol xml NOT NULL, Comment varchar(1000) NULL, CONSTRAINT PK_foo PRIMARY KEY CLUSTERED (KeyCol) ) GO IF OBJECT_ID('dbo.bar') IS NOT NULL DROP PROCEDURE dbo.bar GO CREATE PROCEDURE dbo.bar @Key char(12), @Value xml, @Comment varchar(1000) AS SET NOCOUNT ON DECLARE @StartTranCount tinyint; BEGIN TRY SELECT @StartTranCount = @@TRANCOUNT; IF @StartTranCount = 0 BEGIN TRAN; BEGIN TRY --SELECT @StartTranCount = 'fish' INSERT dbo.foo (KeyCol, ValueCol, Comment) VALUES (@Key, @Value, @Comment); END TRY BEGIN CATCH IF ERROR_NUMBER() = 2627 --PK violation UPDATE dbo.foo SET ValueCol = @Value, Comment = @Comment WHERE KeyCol = @Key; ELSE RAISERROR ('Tits up', 16, 1); END CATCH IF @StartTranCount = 0 COMMIT TRAN; END TRY BEGIN CATCH IF @StartTranCount = 0 AND XACT_STATE() <> 0 ROLLBACK TRAN; RETURN -1 END CATCH --Without this, we'll send -4 if we hit the UPDATE CATCH block above --RETURN 0 GO --Run with RETURN 0 and fish line commented out DECLARE @rtn int EXEC @rtn = dbo.bar 'abcdefghijkl', '<foobar />', 'testing' SELECT @rtn; SELECT * FROM dbo.foo DECLARE @rtn int EXEC @rtn = dbo.bar 'abcdefghijkl', '<foobar2 />', 'testing2' --updated OK but we get @rtn = -4 SELECT @rtn; SELECT * FROM dbo.foo --uncomment fish line DECLARE @rtn int EXEC @rtn = dbo.bar 'abcdefghijkl', '<foobar />', 'testing' --Hit outer CATCH, @rtn = -1 as expected SELECT @rtn; SELECT * FROM dbo.foo

• help needed on libcurl programming in sending HTTP HEAD Request.

  - by Mani

  Hi all, I need clarifications on using libcurl for the following: I need to send an http HEAD request shown as below :: HEAD /mshare/3/30002:12:primary/stream_xNKNVH.mpeg HTTP/1.1 Host: 192.168.70.1:8080 Accept: */* User-Agent: Kreatel_IP-STB getcontentFeatures.dlna.org: 1 The code I wrote (shown below) , sends the HEAD Request in slightly different way: curl_global_init(CURL_GLOBAL_ALL); CURL* ctx = NULL; const char *url = "http://192.168.70.1:8080/mshare/3/30002:12:primary/stream_xNKNVH.mpeg" ; char *returnString; struct curl_slist *headers = NULL; ctx = curl_easy_init(); headers = curl_slist_append(headers,"Accept: */*"); headers = curl_slist_append(headers,"User-Agent: Kreatel_IP-STB");\ headers = curl_slist_append(headers,"getcontentFeatures.dlna.org: 1"); headers = curl_slist_append(headers,"Pragma:"); headers = curl_slist_append(headers,"Proxy-Connection:"); curl_easy_setopt(ctx,CURLOPT_HTTPHEADER , headers ); curl_easy_setopt(ctx,CURLOPT_NOBODY ,1 ); curl_easy_setopt(ctx,CURLOPT_VERBOSE, 1); curl_easy_setopt(ctx,CURLOPT_URL,url ); curl_easy_setopt(ctx,CURLOPT_NOPROGRESS ,1 ); curl_easy_perform(ctx); curl_easy_cleanup(ctx); curl_global_cleanup(); The code shown above sends the HEAD Request in slightly different form (shown below) HEAD http://192.168.70.1:8080/mshare/3/30002:12:primary/stream_xNKNVH.mpeg HTTP/1.1 Host: 192.168.70.1:8080 Proxy-Connection: Keep-Alive Accept: */* User-Agent: Kreatel_IP-STB getcontentFeatures.dlna.org: 1 Can any one , share the appropriate code ?

• Unable to pass variables from one view to another

  - by jerincbus

  I have a detail view that includes three UIButtons, each of which pushes a different view on to the stack. One of the buttons is connected to a MKMapView. When that button is pushed I need to send the latitude and longitude variables from the detail view to the map view. I'm trying to add the string declaration in the IBAction: - (IBAction)goToMapView { MapViewController *mapController = [[MapViewController alloc] initWithNibName:@"MapViewController" bundle:nil]; mapController.address = self.address; mapController.Title = self.Title; mapController.lat = self.lat; mapController.lng = self.lng; //Push the new view on the stack [[self navigationController] pushViewController:mapController animated:YES]; [mapController release]; mapController = nil; } But I get this when I try to build: 'error: incompatible types in assignment' for both lat and lng variables. So my questions are am I going about passing the variables from one view to another the right way? And does the MKMapView accept latitude and longitude as a string or a number?

• Recursive problem...

  - by Chronos

  Guys, I'm new to java and multithreading..... and I have a following problem: I have two classes running in two different threads. Class A and Class B. Class A has the method "onNewEvent()". Once that method is invoked, it will ask class B to do some work. As soon as B finishes the work it invokes onJobDone() method of the class A. Now... here comes the problem... what I want is to create new job within onJobDone() method and to send it again to B. here is what I do (pseudo code) ... in the sequence of execution A.onNewEvent(){ //create job //ask B to do it B.do() } B.do{ // Do some stuff A.jobDone() } A.onJobDOne(){ B.do() //doItAgain // print message "Thank you for doing it" } The problem is... that message "Thank you for doing it" never gets printed... in fact, when onJobDone() method is invoked, it invokes B.do()... because B.do() is very fast, it invokes onJobDone() immediatly... so execution flow never comes to PRINT MESSAGE part of code... I suppose this is one of the nasty multithreading problems.... any help would be appreciated.
