• Klazuka/Kal incorporation issue

  - by user1292943

  I'm having a little issue. I am trying to incorporate the Klazuka/Kal project into my project. I've done the following: I added the Kal.xcodeproj and all files to my project Under Build Phases, I've added Kal to "Target Dependencies" Under Build Phases, I've added libKal.a under "Link Binary With Libraries" Under Build Phases, I've added Kal.bundle to "Copy Bundle Resources" Under Build Settings, I've added "“$(BUILT_PRODUCTS_DIR)” (or “$(BUILT_PRODUCTS_DIR)/static_library_name”" for "Header Search Paths" and "User Header Search Paths". Under Build Settings, I've added the path to Kal under "Library Search Paths" Under Build Settings, I've added -ObjC, -all_load, and -force_load under "Other Linker Flags" I've edited my Build Scheme and list the Kal Target prior to my main application target with Analyze, Test, Run, Profile, and Archive all checked. I've attempted to follow the steps from here on Stack Overflow: iphone: Kal calendar not running in xcode 4.2 and here: Trying to integrate a Calendar library that was built for versions of iOS before iOS5 into my new project in XCode 4 using iOS5 - How to port? and here: I added my project and Kal Calendar's project in a workspace, still won't work in Xcode 4 and also on this site: http://blog.carbonfive.com/2011/04/04/using-open-source-static-libraries-in-xcode-4/#configuring_the_projects_scheme I try to import the "Kal.h" file but am getting a File Not Found error when I try to build. I'm obviously missing something, just not sure what. Can anyone please help? Thanks for any assistance!!

• Problem with .release behavior in file_operations

  - by Yannick

  Hello, I'm dealing with a problem in a kernel module that get data from userspace using a /proc entry. I set open/write/release entries for my own defined /proc entry, and manage well to use it to get data from userspace. I handle errors in open/write functions well, and they are visible to user as open/fopen or write/fwrite/fprintf errors. But some of the errors can only be checked at close (because it's the time all the data is available). In these cases I return something different than 0, which I supposed to be in some way the value 'close' or 'fclose' will return to user. But whatever the value I return my close behave like if all is fine. To be sure I replaced all the release() code by a simple 'return(-1);' and wrote a program that open/write/close the /proc entry, and prints the close return value (and the errno). It always return '0' whatever the value I give. Behavior is the same with 'fclose', or by using shell mechanism (echo "..." /proc/my/entry). Any clue about this strange behavior that is not the one claimed in many tutorials I found? BTW I'm using RHEL5 kernel (2.6.18, redhat modified), on a 64bit system. Thanks. Regards, Yannick

• How to disable form submit if the username is not available

  - by Rajasekar

  I have checked the user name availability. The problem is, even if the username is not available, the form is posting. Edited Code: <SCRIPT type="text/javascript"> $(document).ready(function(){ $("#emailch").change(function() { var usr = $("#emailch").val(); if(usr.length >= 3) { $("#status").html('<img src="images/loader.gif" align="absmiddle">&nbsp;Checking availability...'); $.ajax({ type: "POST", url: "includes/check.php", data: "username="+ usr, success: function(msg){ $("#status").ajaxComplete(function(event, request, settings){ if(msg == 'OK') { $("#username").removeClass('object_error'); // if necessary $("#username").addClass("object_ok"); $(this).html('&nbsp;<img src="images/tick.gif" align="absmiddle">'); } else { $("#username").removeClass('object_ok'); // if necessary $("#username").addClass("object_error"); $(this).html(msg); } }); } }); } else { $("#status").html('<font color="red">The username should have at least <strong>3</strong> characters.</font>'); $("#username").removeClass('object_ok'); // if necessary $("#username").addClass("object_error"); } }); }); </SCRIPT> What I want is that, the form should not be posted if the user name is not available. I have tried by using return false; in IF CONDITION but it fails. Please suggest any alternate method. Any help will be appreciated.

• What are some commonly used source code check-in policies?

  - by rwmnau

  I'm curious what code review policies other development shops apply to their source code when it's checked into the source control repository. I'm setting up a TFS (Team Foundation) server, and I'd like to apply some check-in policies to start to stamp out bad practices. For example, I was thinking of starting with the following couple, so this is the kind of stuff I'm looking for: Prohibit empty "Catch" blocks. This would prevent applications from swallowing any exceptions without at least requiring a comment explaining why it's not necessary to do anything with the exception. Prohibit "Catch ex as Exception" generic exception handling. Instead, require code to catch specific types of exceptions and deal with them appropriately, instead of just building catch-all handling. Require a check-in comment. This one should be self-explanatory, though it seems that TFS (and most other source-control systems) don't require a comment by default. While these are just examples, they're where I'm thinking of starting, and while I'd like some additional examples of what's popular, I'm open to feedback on these. Also, though we're a mostly .NET shop, I imagine the popular policies are universal across languages and IDEs (we have some Java development and a few people who will use the repository develop with Eclipse).

• How does one gets started with Winforms style applications on Win32?

  - by Billy ONeal

  EDIT: I'm extremely tired and frustrated at the moment -- please ignore that bit in this question -- I'll edit it in the morning to be better. Okay -- a bit of background: I'm a C++ programmer mostly, but the only GUI stuff I've ever done was on top of .NET's WinForms platform. I'm completely new to Windows GUI programming, and despite Petzold's excellent book, I'm extremely confused. Namely, it seems that most every reference on getting started with Win32 is all about drawing lines and curves and things -- a topic about which (at least at present time) I couldn't care less. I need a checked list box, a splitter, and a textbox -- something that would take less than 10 minutes to do in Winforms land. It has been recommended to me to use the WTL library, which provides an implementation of all three of these controls -- but I keep getting hung up on simple things, such as getting the damn controls to use the right font, and getting High DPI working correctly. I've spent two freaking days on this, and I can't help but think there has to be a better reference for these kinds of things than I've been able to find. Petzold's book is good, but it hasn't been updated since Windows 95 days, and there's been a LOT changed w.r.t. how applications should be correctly developed since it was published. I guess what I'm looking for is a modern Petzold book. Where can I find such a resource, if any?

• Create a real time web application using .net framework and azure - very confused

  - by test

  Let us say I would like a simple (yet complex) web application where there is continuous READING AND WRITING to the sql azure database. Let us say I am tracking a location, and I would like it to be updated very frequently (lets take the worst case: 1 second). From the little knowledge I have, I think that this involves the use of the database to continuously write the location to the database, and continuously read from the database to update another person through a website. Do you please have any suggestion which technologies can I use? Is there a simple way? I heard about node.js, signalR. I have no idea how to use them, if they are really what I need. the last tutorial I checked out simply uses a while(true) loop..but I don't think that that's something good to keep a thread continuously busy... Do I have to create some background task? Do I have to create some web service? This is a school project and I wish not to go for the most difficult option, but if there is some sort of solution, challenge accepted :) Can you please help me? Since I have asked many questions here and yet I have no solution in mind

• Unable to save data in database manually and get latest auto increment id, cakePHP

  - by shabby

  I have checked this question as well and this one as well. I am trying to implement the model described in this question. What I want to do is, on the add function of message controller, create a record in thread table(this table only has 1 field which is primary key and auto increment), then take its id and insert it in the message table along with the user id which i already have, and then save it in message_read_state and thread_participant table. This is what I am trying to do in Thread Model: function saveThreadAndGetId(){ //$data= array('Thread' => array()); $data= array('id' => ' '); //Debugger::dump(print_r($data)); $this->save($data); debug('id: '.$this->id); $threadId = $this->getInsertID(); debug($threadId); $threadId = $this->getLastInsertId(); debug($threadId); die(); return $threadId; } $data= array('id' => ' '); This line from the above function adds a row in the thread table, but i am unable to retrieve the id. Is there any way I can get the id, or am I saving it wrongly? Initially I was doing the query thing in the message controller: $this->Thread->query('INSERT INTO threads VALUES();'); but then i found out that lastId function doesnt work on manual queries so i reverted.

• Unserializing an API return object (PHP/Ebay API)

  - by DavidYell

  I have been working with the Ebay api for a project and have found it great. I have however found a problem now, more PHP related. When I read my items from Ebay, I store a bunch of details in the database. Currently, just for the sake of it really, I serialize the whole return object and store it in the database in a related table. The idea being, that when I display my information, I have all the details to hand should I need them. The problem arises in that the pricing information is always in a sub object. [ConvertedAdjustmentAmount] => __PHP_Incomplete_Class Object ( [__PHP_Incomplete_Class_Name] => eBayAmountType [_] => 0 [currencyID] => USD ) As you can see when I unserialize my object, my cunning plan falls foul of the Incomplete class problem. I have checked the following question, without success. http://stackoverflow.com/questions/965611/forcing-access-to-php-incomplete-class-object-properties The main issue lies, as far as I can see, in that the price class is stored in the Ebay api, so how do I recreate it? I have been reading this page, http://uk3.php.net/manual/en/function.unserialize.php and trying to figure out, unserialize_callback_func which I can't figure out either, so any help would be appreciated!

• Apache Lucene: Is Relevance Score Always Between 0 and 1?

  - by Eamorr

  Greetings, I have the following Apache Lucene snippet that's giving me some nice results: int numHits=100; int resultsPerPage=100; IndexSearcher searcher=new IndexSearcher(reader); TopScoreDocCollector collector=TopScoreDocCollector.create(numHits,true); Query q=parser.parse(queryString); searcher.search(q,collector); ScoreDoc[] hits=collector.topDocs(0*resultsPerPage,resultsPerPage).scoreDocs; Results r=new Results(); r.length=hits.length; for(int i=0;i<hits.length;i++){ Document doc=searcher.doc(hits[i].doc); double distanceKm=getGreatCircleDistance(lucene2double(doc.get("lat")), lucene2double(doc.get("lng")), Double.parseDouble(userLat), Double.parseDouble(userLng)); double newRelevance=((1/distanceKm)*Math.log(hits[i].score)/Math.log(2))*(0-1); System.out.println(hits[i].doc+"\t"+hits[i].score+"\t"+doc.get("content")+"\t"+"Km="+distanceKm+"\trlvnc="+String.valueOf(newRelevance)); } What I want to know, is hits[i].score always between 0 and 1? It seems that way, but I can't be sure. I've even checked the Lucene documentation (class ScoreDocs) to no avail. You'll see I'm calculating the log of the "newRelevance" value, which is based on hits[i].score. I need hits[i].score to be between 0 and 1, because if it is below zero, I'll get an error; above 1 and the sign will change from negative to positive. I hope some Lucene expert out there can offer me some insight. Many thanks,

• CoreMidi _MIDINetworkNotificationContactsDidChange symbol not found

  - by Domestic Cat

  I'm getting the following error after a crash in an iPad app that uses CoreMIDI (The * are to blank out the app name): Dyld Error Message: Symbol not found: _MIDINetworkNotificationContactsDidChange Referenced from: /var/mobile/Applications/8F08B78E-929D-4C5A-9F02-08FD5743C17F/***.app/*** Expected in: /System/Library/Frameworks/CoreMIDI.framework/CoreMIDI in /var/mobile/Applications/8F08B78E-929D-4C5A-9F02-08FD5743C17F/***.app/*** Dyld Version: 179.4 When the app launches, I listen for MIDI Network Sessions using [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(sessionDidChange:) name:MIDINetworkNotificationSessionDidChange object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(sessionDidChange:) name:MIDINetworkNotificationContactsDidChange object:nil]; Which seems to be what is causing the crash. This is after I call session = [MIDINetworkSession defaultSession]; session.enabled = YES; session.connectionPolicy = MIDINetworkConnectionPolicy_Anyone; MIDIClientCreate(CFSTR("MidiManager"), midiNotifyProc, (void*)self, &midiClientRef); This kind of looks like CoreMIDI library has not been included in the build. Problem is, it IS included in the build as a required framework. (And the deployment target is set to 4.2). I can run the build fine on my iPad and have been testing extensively with other users' iPads also with no problems whatsoever. Also, this is an update to an existing app that has had several updates already with no problems. I just double checked my deployment build and the framework is definitely included, and I just installed that build onto my iPad (with a different provisioning profile from the store) and it works fine also. What could be happening? Could it be that Xcode just did a bad build for the one I sent to Apple, or am I missing something obvious? Could I change the MIDINetworkNotificationSessionDidChange notification symbol to a literal string (@"MIDINetworkNotificationSessionDidChange") to fix things for the mean time? Thanks for any help!

• In M-V-VM where does my code go?

  - by Nate Bross

  So, this is a pretty basic question I hope. I have a web service that I've added through Add Service Reference. It has some methods to get list and get detail of a perticular table in my database. What I'm trying to do is setup a UI as follows: App Load Load service proxy Call the GetList(); method display the results in a ListBox control User Double Clicks item in ListBox, display a modal dialog with a "detail" view I'm extremely new to using MVVM, so any help would be greatly appreciated. Additional information: // Service Interface (simplification): interface IService { IEnumerable<MyObject> GetList(); MyObject GetDetail(int id); } // Data object (simplification) class MyObject { public int ID { get; set; } public string Name { get; set; } } I'm thinking I should have something like this: MainWindow MyObjectViewUserControl Displays list Opens modal window on double click Specific Questions: What would my ViewModel class look like? Where does the code to handle the double click go? Inside the UserControl? Sorry for the long details, but I'm very new to the whole thing and I'm not educated enough to ask the right questions. I checked out the MVVM Sample from wpf.codeplex.com and something isn't quite clicking for me yet, because it seems very confusing.

• Git repos over multiple machines - backups and keeping in sync

  - by a-or-b

  I'm new to git so please feel free to RTFM me... I have multiple development sites (none of which can communicate via a network with each other) and am working on a few projects (with a few people) at any one time. What I would ideally have is at each site a centralized repository that can be pulled from but development would occur in our own (personal) repos. Then I would like to be able to sync across the centralized repos (via USB key for example). I want a centralized repo at each location as (1) I'm new to git and do break my (personal) local repo by playing around and (2) some projects get put on hold so I want to be able to free up disk space by deleting them. This is the "backup" part of my question. I was also hoping to be able to use 'git clone --bare' for my centralized repos (and the USB key repos to?) as we don't need the full checkout, just the git benefits. However I can't seem to get a bare repo to work as repo I can push from. I've used 'git remote' to set up an remote origin (similar to http://toolmantim.com/thoughts/setting_up_a_new_remote_git_repository) but I can't get 'git push' to work - it seems I need a checked-out repo. . Does anyone else use this sort of repo/development structure or is there something fundamental about git usage that I'm missing? . A solution that I thought about that might not work - If I had a 'git clone --bare' at each site and then use a git repo on my removable media which has remotes set up for each site then I could ('pull') sync my USB key with each repo. But then can I update the site repo from my USB key? Could I push from USB?

• Searching in graphs trees with Depth/Breadth first/A* algorithms

  - by devoured elysium

  I have a couple of questions about searching in graphs/trees: Let's assume I have an empty chess board and I want to move a pawn around from point A to B. A. When using depth first search or breadth first search must we use open and closed lists ? This is, a list that has all the elements to check, and other with all other elements that were already checked? Is it even possible to do it without having those lists? What about A*, does it need it? B. When using lists, after having found a solution, how can you get the sequence of states from A to B? I assume when you have items in the open and closed list, instead of just having the (x, y) states, you have an "extended state" formed with (x, y, parent_of_this_node) ? C. State A has 4 possible moves (right, left, up, down). If I do as first move left, should I let it in the next state come back to the original state? This, is, do the "right" move? If not, must I transverse the search tree every time to check which states I've been to? D. When I see a state in the tree where I've already been, should I just ignore it, as I know it's a dead end? I guess to do this I'd have to always keep the list of visited states, right? E. Is there any difference between search trees and graphs? Are they just different ways to look at the same thing?

• iPhone Simulator - Restores Plist - Weird Issue

  - by David Schiefer

  Hi All, today I've come across a rather weird issue. After adding code to validate a key (i added it below), the Simulator refuses to let go of the old plist file. I deleted the simulator folder in the Application Support folder, then deleted the *build directory and restarted xcode & build & run my app...still the same issue. the old plist is still there and 100% identical. I then changed the identifier and the snippet's validation keys, the plist however stayed the same. basically, no matter what i do it won't go. the same thing happens on the iphone itself. I have checked through the code, i don't create the key anywhere, but it still returns YES for it at every restart. Here's the code I added: + (void)initialize{ ////////////////////////////SPECIFING THE PREDATA/////////////////// NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; NSDictionary *appDefaults = [NSDictionary dictionaryWithObject:[NSNumber numberWithBool:NO] forKey:@"protect"]; [defaults registerDefaults:appDefaults]; } if ([[NSUserDefaults standardUserDefaults] boolForKey:@"protect"] == NO) { [navigationController pushViewController:help animated:YES]; [help.navigationItem hidesBackButton]; } else { [window addSubview:passcode.view]; [self performSelector:@selector(responder) withObject:nil afterDelay:1]; } as a result, it will always go for the else option, which for some reason, doesn't get executed either. I assumed an error but the log is empty and there's no crash.

• Android lifecycle of thread-based game

  - by ehehhh

  I ran into a bit of trouble while trying to get my game to work correctly after being put to the background by the user or a phone call for example. My app has a SurfaceView class called GameView, which has the onDraw() method to do all the necessary drawing for my game and two threads - one for calling the onDraw() and one for doing the necessary calculations for the game's logic. I succesfully implemented onPause() and onResume(). (I paused both threads when back button was pressed and resumed them after user cancelled in the AlertDialog.) Now I would like to have the game paused the same way when onStop() gets called. I put both threads on pause and saved my characters location in the savedInstanceState, but when I start my app again, no method gets called (I checked with Logcat). I believe onRestart() should be called first, then onStart() and then onResume(), but none of that happens. What am I doing wrong? (Didn't include any code, because it seems to be a problem of me not understanding the lifecycle, not a problem in code. If it seems necessary, I'll post the parts you request.)

• perl regular expressions substitution/replacement using variables with special characters

  - by user961627

  Okay I've checked previous similar questions and I've been juggling with different variations of quotemeta but something's still not right. I have a line with a word ID and two words - the first is the wrong word, the second is right. And I'm using a regex to replace the wrong word with the right one. $line = "ANN20021015_0104_XML_16_21 A$xAS A$xASA"; @splits = split("\t",$line); $wrong_word = quotemeta $splits[1]; $right_word = quotemeta $splits[2]; print $right_word."\n"; print $wrong_word."\n"; $line =~ s/$wrong_word\t/$right_word\t/g; print $line; What's wrong with what I'm doing? Edit The problem is that I'm unable to retain the complete words - they get chopped off at the special characters. This code works perfectly fine for words without special characters. The output I need for the above example is: ANN20021015_0104_XML_16_21 A$xASA A$xASA But what I get is ANN20021015_0104_XML_16_21 A A Because of the $ character.

• Windows Server 2008 R2 File Permissions

  - by Fly_Trap

  I’m having some problems understanding some particular file permissions behaviour. Here are the steps to reproduce: Log into the server using the default Administrator account Create a text file (testfile.txt) in C:\ProgramData containing some arbitrary text Create a new user account and make it a member of the Administrators group Log in using new account and open C:\ProgramData\testfile.txt Edit the text and try to save Upon clicking save I’m presented with the save as dialog, which indicates that i do not have the necessary permissions to edit the file. This seems odd considering that the new user account is a member of Administrators. When I view the permissions of the file I can see the there are three groups listed, System, Administrators and Users. SYSTEM and Administrators have full permissions, however, Users only has the Read & Execute and Read permissions checked. It would appear that when I open the testfile.txt from the new users account, it opens in the context of the Users group, despite being a member of Administrators, is this correct? It would certainly explain the behaviour. The reason that this is an issue for me is that if I deploy an application via 'Run as Administrator', will normal users be able to edit the text files I install to ProgramData. Is this behaviour confined to Windows server or is it the same in Vista and Win7.

• gwt seperate modules with no code sharing

  - by Code freak

  Hi, I have to make a web application using GWT. The project has a core module that'll expose a set of apis to be used by other apps; each of these app are unrelated. Each shall be loaded in a separate iframe. My idea was to compile core into core.js and each app shall have its own app1.js app2.js and so on... App1 script type="text/javascript" src="core.js" ></script> script type="text/javascript" src="app1.js" ></script> with this design, due to browser caching, each app laod only the app.js which should be smaller ~20kb in size. Making a core module is straightforward but the apps are problematic. The reason being after compilation, each app contains the entire GWT library - this substantially increases the download size of the complete webapp. Can anyone suggest a way to get aroung this problem ? I've checked similar questions on SO, but failed to find a simple working answer fr the problem. Thanks for any help.

• How to invoke make install for one subdirectory of Qt project

  - by chalup

  I'm working on custom library and I wish users could just use it by adding: CONFIG += mylib to their pro files. This can be done by installing mylib.prf file to %QTDIR%/mkspec/features. I've checked out in Qt Mobility project how to create and install such file, but there is one thing I'd like to do differently. If I correctly understood the pro/pri files of Qt Mobility, inside the example projects they don't really use CONFIG += mobility, instead they add QtMobility sources to include path and share the *.obj directory with main library project. For my library I'd like to have examples that are as independent projects as possible, i.e. projects that can be compiled from anywhere once MyLib is compiled and installed. I have following directory structure: mylib | |- examples |- src |- tests \- mylib.pro It seems that the easiest way to achieve what I described above is creating mylib.pro like this: TEMPLATE = subdirs SUBDIRS += src SUBDIRS += examples tests:SUBDIRS += tests And somehow enforce invoking "cd src && make install" after building src. What is the best way to do this? Of course any other suggestions for automatic library deployment before examples compilation are welcome.

• Django Interrupted system call when sending email

  - by mhost

  Hi, Sometimes, when submitting a form (pretty much any form on my site that sends me an email), I get the following error: File "/usr/lib/python2.5/smtplib.py", line 603, in starttls (resp, reply) = self.docmd("STARTTLS") File "/usr/lib/python2.5/smtplib.py", line 378, in docmd return self.getreply() File "/usr/lib/python2.5/smtplib.py", line 352, in getreply line = self.file.readline() File "/usr/lib/python2.5/socket.py", line 381, in readline data = self._sock.recv(self._rbufsize) error: (4, 'Interrupted system call') My code is sending email via gmail. I am also using django contact-form which does the same thing. The problem doesn't always happen. It seems very random. At one point today it got so bad that it displayed the error every time I submitted a form. Restarting apache fixes the problem for one submission and then it does it again. I have checked the RAM and there is plenty available (about 350MB available). Can someone lead me in the right direction? What does this error mean? What can I do to prevent this. Thanks.

  I was writing a simple test application. There are two radio buttons within the app. There id's are "radio_red" and "radio_blue". I wanted to create an onClickListener event that read the text associated to the button and then returned a basic "Right" or "Wrong" toast. Here is a sample of the code: private OnClickListener radio_listener = new OnClickListener() { public void onClick(View v){ RadioButton rb = (RadioButton) v; String ans = rb.getText().toString(); String an1 = ""; if (ans.trim() == "Yes") { ans = "That's Right."; } else if (ans.trim() == "No") { ans = "thats wrong."; } else { ans = "none."; } Toast.makeText(v.getContext(), ans , Toast.LENGTH_SHORT).show(); } So far no joy. Here is my code snippet. I've checked my "main.xml" and the text associated to the buttons are referneced correctly. I added trim to make sure of that. However, all that is ever returned in the toast is "none." What am I missing? Thanks in advance for any help.
