  • jQuery ajax call doesn't seem to do anything at all

    - by icemanind
    I am having a problem with making an ajax call in jQuery. Having done this a million times, I know I am missing something really silly here. Here is my javascript code for making the ajax call: function editEmployee(id) { $('#<%= imgNewEmployeeWait.ClientID %>').hide(); $('#divAddNewEmployeeDialog input[type=text]').val(''); $('#divAddNewEmployeeDialog select option:first-child').attr("selected", "selected"); $('#divAddNewEmployeeDialog').dialog('open'); $('#createEditEmployeeId').text(id); var inputEmp = {}; inputEmp.id = id; var jsonInputEmp = JSON.stringify(inputEmp); debugger; alert('Before Ajax Call!'); $.ajax({ type: "POST", url: "Configuration.aspx/GetEmployee", data: jsonInputEmp, contentType: "application/json; charset=utf-8", dataType: "json", success: function (msg) { alert('success'); }, error: function (msg) { alert('failure'); } }); } Here is my CS code that is trying to be called: [WebMethod] public static string GetEmployee(int id) { var employee = new Employee(id); return Newtonsoft.Json.JsonConvert.SerializeObject(employee, Newtonsoft.Json.Formatting.Indented); } When I try to run this, I do get the alert that says Before Ajax Call!. However, I never get an alert back that says success or an alert that says failure. I did go into my CS code and put a breakpoint on the GetEmployee method. The breakpoint did hit, so I know jQuery is successfully calling the method. I stepped through the method and it executed just fine with no errors. I can only assume the error is happening when the jQuery ajax call is returning from the call. Also, I looked in my event logs just to make sure there wasn't an ASPX error occurring. There is no error in the logs. I also looked at the console. There are no script errors. Anyone have any ideas what I am missing here? `

  • Overriding windows authentication for a .NET application

    - by JoshReedSchramm
    I have a .NET application where the homepage (default.aspx) should be accessible by anyone. There is also a reporting page (reporting.aspx) that I want to secure via windows authentication and only allow access to a particular set of AD groups. Right now the way my web.config is setup it is securing the reporting page but on the home page it prompts the user for login credentials. If they hit esc they can continue to the page though so it isnt actually securing it. I need to prevent it from prompting the user. How do i need to setup my config. Here is what i have now - <system.web> <authentication mode="Windows" /> <identity impersonate="true" /> <authorization> <allow roles="BUILTIN\Administrators, DomainName\Manager" /> <deny users="?" /> </authorization> ...MORE STUFF... </system.web> <location path="default.aspx"> <system.web> <identity impersonate="false" /> <authorization> <allow users="*"/> </authorization> </system.web> </location>

  • Is there an easier way with jQuery accordions?

    - by Josh
    I've been struggling with a feature I've been trying to create for sometime. The idea here is that the user sees the little thumbnail + headline, as well as the Posted By information. They can then click on the headline to expand to the article or click on the "Comments" link to expand directly to the comments made on the article. Or, if they want they can view comments by clicking on the headline(to expand to the article), then click on View Comments (to expand to the comments). In the end, a modular yet flexible and functional open/close system to view latest news. Here is what I've been working on: (I put all my code in one place so its easier on whomever may look at this to view) http://notedls.com/pointtest.html This is what I'm shooting for, but it's far from what I want ;( It's using the jQuery 1.6 plugin, which 1.8 is out but I'm far from being a master or expert at this and I don't think I could build from the ground up. I've already edited this plugin to get it to work like this, but as you can see, the AUTHOR and Comments start making shit hit the fan ;; It's because the code is calling the "A TAG" for the header; which is the headline. Does anyone know any easier way to achieve what I'm envisioning or possible a way to fix this current code? I'm pretty desperate at this point ;;

  • jquery .live() event interactions

    - by ddango
    Let's say I have a scenario where I have a global plugin (or at least a plugin that binds to a wider array of events). This plugin takes a selector, and binds a live click to it. Something in pseudo-jquery that might look like this: $.fn.changeSomething = function(){ $(this).live("change", function(){ alert("yo");}); } On another page, I have an additional live binding something like this: $("input[type='checkbox']").live("click", function(){alert("ho");}); Within this scenario, the checkbox would ideally end up being bound to both live events. What I'm seeing is that the change event fires as it should, and I'm alerted "yo". However, using this live click event, I never trigger it. However, using an explicit click binding, I DO hit it. The easy workaround is to trigger a click event at the end of the live change handler, but this seems janky to me. Any ideas? Note that this is using jquery 1.4.2 and only occurs in IE8 (I supposed 6/7 would too, but I haven't tested them).

  • Qt QFileDialog - native dialogs only with static functions?

    - by darron
    I'm trying to simply save a file. However, I need a filename entered without a suffix to automatically get a default suffix (which setDefaultSuffix() does). I'd rather not completely lose the native save dialog just for this. exec() is not overloaded from QDialog, so it totally bypasses the native hook (ignoring the DontUseNativeDialog option even if it's false). If I disable the file overwrite warning and append the default suffix myself after the function returns, then I'd be re-opening the dialog if the user did not want to overwrite... and that's just ugly. Is there some signal I can catch and quickly inject the default suffix if it's not there? I'm guessing not, since it's a native dialog. Is there something I'm doing wrong with the filter? I only have one filter choice. It should use that extension. This seems pretty lame. Launching the save dialog and simply typing "test" should never result in an extensionless file. "test.", yes. "test" no way. That'll really confuse the users when they hit Load and can't see the file they just saved. I guess the cross-platform part of Qt is giving me lowest common denominator file dialog functionality?

  • Retrieving many huge sized EPS files and converting them to JPEG in ASP.NET application

    - by Ashish Gupta
    I have many (600) EPS files(300 KB - 1 MB) in database. In my ASP.NET application (using ASP.NET 4.0) I need to retrieve them one by one and call a web service which would convert the content to the JPEG file and update the database (JPEGContent column with the JPEG content). However, retrieving the content for 600 of them itself takes too long from the SQL management studio itself (takes 5 minutes for 10 EPS contents). So I have two issues:- 1) How to get the EPS content ( unfortunately, selecting certain number of content is not an option :-( ):- Approach 1:- foreach(var DataRow in DataTable.Rows) { // get the Id and byte[] of EPS // Call the web method to convert EPS content to JPEG which would also update the database. } or foreach(var DataRow in DataTable.Rows) { // get only the Id of EPS // Hit database to get the content of EPS // Call the web method to convert EPS content to JPEG which would also update the database. } or Any other approach? 2) Converting EPS to JPEG using a web method for 600 contents. Ofcourse, each call would be a long running operation. Would task parellel library (TPL) be a better way to achieve this? Also, is doing the entire thing in a SQL CLR function a good idea?

  • Play multiple audio files using AVAudioPlayer

    - by inScript09
    Hi all, I am planning on releasing 10 of my song recordings for free but bundled in an iphone app. They are not available on web or itunes or anywhere as of now. I am new to iphone sdk (latest) as you can imagine, so I have been going through the developer documentation, various forums and stackoverflow to learn. Apple's avTouch sample application was a great start. But I want my app to play all the 10 tracks one by one. All the songs are added to resources folder and are named as track1, track2...track10. In the avTouch app code I can see the following 2 parts which is where I think I need to make changes to achieve what I am looking for. But I am lost. // Load the array with the sample file NSURL *fileURL = [[NSURL alloc] initFileURLWithPath: [[NSBundle mainBundle] pathForResource:@"sample" ofType:@"m4a"]]; - (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag { if (flag == NO) NSLog(@"Playback finished unsuccessfully"); [player setCurrentTime:0.]; [self updateViewForPlayerState]; } can anyone please help me on 1. how to load the array with all the 10 tracks which are added to resources folder 2. and when I hit play, player should start the first track. when the 1st track ends 2nd track should start and so on for the remaining tracks. Thank You

  • C malloc assertion help

    - by Chris
    I am implementing a divide and conquer polynomial algorithm so i can bench it against an opencl implementation, but i can't seem to get malloc to work. When I run the program it allocates a bunch of stuff, checks some things, then sends the size/2 to the algorithm. Then when I hit the malloc line again it spits out this: malloc.c:3096: sYSMALLOc: Assertion `(old_top == (((mbinptr) (((char *) &((av)-bins[((1) - 1) * 2])) - __builtin_offsetof (struct malloc_chunk, fd)))) && old_size == 0) || ((unsigned long) (old_size) = (unsigned long)((((__builtin_offsetof (struct malloc_chunk, fd_nextsize))+((2 * (sizeof(size_t))) - 1)) & ~((2 * (sizeof(size_t))) - 1))) && ((old_top)-size & 0x1) && ((unsigned long)old_end & pagemask) == 0)' failed. Aborted The line in question is: int *out, .....other vars....; out = (int *)malloc(sizeof(int) * size * 2); I have checked size with fprintf and it is a positive int (usually 50 at that point). I have tried calling malloc with a plain number as well and i still get the error. I'm just stumped at what's going on, and nothing from google that I have found so far has been too helpful. Any ideas what's going on? I'm trying to figure out how to compile a newer GCC in case it's a compiler error, but i really doubt it.

  • JQuery datepicker not working

    - by IniTech
    I'm completely new to JQuery and MVC. I'm working on a pet project that uses both to learn them and I've hit my first snag. I have a date field and I want to add the JQuery datepicker to the UI. Here is what I have done: Added <script src="../../Scripts/jquery-1.3.2.min.js" type="text/javascript"></script> to the site.master Inside my Create.aspx (View), I have <asp:Content ID="Create" ContentPlaceHolderID="MainContent" runat="server"> <h2> Create a Task</h2> <% Html.RenderPartial("TaskForm"); %> </asp:Content> and inside "TaskForm" (a user control) I have: <label for="dDueDate"> Due Date</label> <%= Html.TextBox("dDueDate",(Model.Task.TaskID > 0 ? string.Format("{0:g}",Model.Task.DueDate) : DateTime.Today.ToString("MM/dd/yyyy"))) %> <script type="text/javascript"> $(document).ready(function() { $("#dDueDate").datepicker(); }); </script> As you can see, the above checks to see if a task has an id 0 (we're not creating a new one) if it does, it uses the date on the task, if not it defaults to today. I would expect the datepicker UI element to show up, but instead I get: "Microsoft JScript runtime error: Object doesn't support this property or method" on the $("#dDueDate").datepicker(); Ideas? It is probably a very simple mistake, so don't over-analyze. As I said, this is the first time I've dealt with MVC or JQuery so I'm lost as to where to start.

  • How to properly implement cheat codes?

    - by Axarydax
    Hi, what would be the best way to implement kind of cheat codes in general? I have WinForms application in mind, where a cheat code would unlock an easter egg, but the implementation details are not relevant. The best approach that comes to my mind is to keep index for each code - let's consider famous DOOM codes - IDDQD and IDKFA, in a fictional C# app. string[] CheatCodes = { "IDDQD", "IDKFA"}; int[] CheatIndexes = { 0, 0 }; const int CHEAT_COUNT = 2; void KeyPress(char c) { for (int i = 0; i < CHEAT_COUNT; i++) //for each cheat code { if (CheatCodes[i][CheatIndexes[i]] == c) { //we have hit the next key in sequence if (++CheatIndexes[i] == CheatCodes[i].Length) //are we in the end? { //Do cheat work MessageBox.Show(CheatCodes[i]); //reset cheat index so we can enter it next time CheatIndexes[i] = 0; } } else //mistyped, reset cheat index CheatIndexes[i] = 0; } } Is this the right way to do it?

  • 'echo' or drop out of 'programming' write HTML then start PHP code again

    - by thecoshman
    For the most part, when I want to display some HTML code to be actually rendered I would use a 'close PHP' tag, write the HTML, then open the PHP again. eg <?php // some php code ?> <p>HTML that I want displayed</p> <?php // more php code ?> But I have seen lots of people who would just use echo instead, so they would have done the above something like <?php // some php code echo("<p>HTML that I want displayed</p>"); // more php code ?> Is their any performance hit for dropping out and back in like that? I would assume not as the PHP engine would have to process the entire file either way. What about when you use the echo function in the way that dose not look like a function, eg echo "<p>HTML that I want displayed</p>" I would hope that this is purely a matter of taste, but I would like to know if I was missing out on something. I personally find the first way preferable (dropping out of PHP then back in) as it helps draw a clear distinction between PHP and HTML and also lets you make use of code highlighting and hinting for your HTML, which is always handy.

  • Algorithms for finding a numerical record in a list of ordered numbers

    - by Ankur
    I have a list of incomplete ordered numbers. I want to find a particular number with as few steps as possible. Are there any improvements on this algorithm, I assume you can count the set size without difficulty - it will be stored and updated every time a new item is added. Your object is to get your cursor over the value x The first number (smallest) is s, and the last number (greatest) is g. Take the midpoint m1 of the set: calculate is x < m1, If yes then s <= x < m1 If no then m1 < x <= g If m1 = x then you're done. Keep repeating till you find x. Basically dividing the set into two parts with each iteration till you hit x. The purpose is to retrieve a numerical id from a very large table to then find the associated other records. I would imagine this is the most trivial kind of indexing available, are there improvements?

  • php get, random records, and the back button

    - by Andrew Heath
    My site has a library full of games, nations, game scenarios, etc. library.php is given a type=___ & id=___ for example library.php?type=scenario&id=ABCD001 library.php saves the id to a session variable and loads an include appropriate for the type This all works just dandy. Now, I wanted to give my users the option of pulling up a random scenario. To do that, I added a special id to the logic within lib-scenario.php (the include) such that if given library.php?type=scenario&id=random the include knows to run an alternate query for a random record rather than for the actual id This also works just dandy... unless someone hits the Random Scenario button two+ times in a row, and decides that the previous random scenario was way cooler, I want to go back to that. Because the http address is always directory/library.php?type=scenario&id=random no matter how many times you click Random Scenario, as soon as you click back you'll be taken to the last page with an alternate address you visited. So, if you start at the Home page, and hit Random Scenario 35 times, then decide the 34th one was what you wanted and click BACK, you'll be put back onto the Home page. I must admit this was not a problem I had anticipated. One of my testers was the first to have the urge to back-up in the random scenario stream and here we are. How can I add back-up functionality to my script?

  • Django's post_save signal behaves weirdly with models using multi-table inheritance

    - by hekevintran
    Django's post_save signal behaves weirdly with models using multi-table inheritance I am noticing an odd behavior in the way Django's post_save signal works when using a model that has multi-table inheritance. I have these two models: class Animal(models.Model): category = models.CharField(max_length=20) class Dog(Animal): color = models.CharField(max_length=10) I have a post save callback called echo_category: def echo_category(sender, **kwargs): print "category: '%s'" % kwargs['instance'].category post_save.connect(echo_category, sender=Dog) I have this fixture: [ { "pk": 1, "model": "animal.animal", "fields": { "category": "omnivore" } }, { "pk": 1, "model": "animal.dog", "fields": { "color": "brown" } } ] In every part of the program except for in the post_save callback the following is true: from animal.models import Dog Dog.objects.get(pk=1).category == u'omnivore' # True When I run syncdb and the fixture is installed, the echo_category function is run. The output from syncdb is: $ python manage.py syncdb --noinput Installing json fixture 'initial_data' from '~/my_proj/animal/fixtures'. category: '' Installed 2 object(s) from 1 fixture(s) The weird thing here is that the dog object's category attribute is an empty string. Why is it not 'omnivore' like it is everywhere else? As a temporary (hopefully) workaround I reload the object from the database in the post_save callback: def echo_category(sender, **kwargs): instance = kwargs['instance'] instance = sender.objects.get(pk=instance.pk) print "category: '%s'" % instance.category post_save.connect(echo_category, sender=Dog) This works but it is not something I like because I must remember to do it when the model inherits from another model and it must hit the database again. The other weird thing is that I must do instance.pk to get the primary key. The normal 'id' attribute does not work (I cannot use instance.id). I do not know why this is. Maybe this is related to the reason why the category attribute is not doing the right thing?

  • "Replay" the steps needed to recreate an error

    - by David
    I am going to create a typical business application that will be used by a few hundred consultants. Normally, the consultants would be presented with an error message with a standard text. As the application will be a complicated one with lots of changes being made to it constantly I would like the following: When an error message is presented, the user has the option to "send" the error message to the developers. The developers should be able to open the incoming file in i.e. Eclipse and debug the steps of the last 10 minutes of work step by step (one line at a time if they want to). Everything should be transparent, meaning that they for example should be able to see the return values of calls to the database. Are there any solutions that offer such functionality today, my preferred language is Python or also Java. I know that there will be a huge performance hit because of such functionality, but that is acceptable as this kind of software is not performance sensitive. It would be VERY nice if the database also had a cronology so that one could query the database for values that existed at the exact time that a specific line of code was run in the application, leading up to the bug.

  • (EXCEL)VBA Spin button which steps through in an sql databases date time

    - by Gulredy
    I have an sql Database table in MySQL which have lots of rows with varied date time values. For example: 2012-08-21 10:10:00 <-- with these date there are around 12 rows 2012-08-21 15:31:00 <-- with these date there are around 5 rows 2012-08-22 11:40:00 <-- with these date there are around 10 rows 2012-08-22 12:17:00 <-- with these date there are around 9 rows 2012-08-22 12:18:00 <-- with these date there are around 7 rows 2012-08-25 07:21:00 <-- with these date there are around 6 rows If the user clicks on the SpinButton1_SpinUp() or SpinButton1_SpinDown() button then it should do the following: The SpinButton1_SpinUp() button should filter out those data from an sql table which is the next after what we are currently on now. Example: We have currently selected: 2012-08-21 15:31:00. The user hits the SpinUp button then the program selects those date from the database, which is the next higher value like this one: 2012-08-22 11:40:00. So the user hits the SpinUp button the data which is selected in the database will change from those with date: 2012-08-21 15:31:00 to those with date: 2012-08-22 11:40:00 The SpinButton1_SpinDown() will do exactly the reverse of the SpinUp button. When the user hits the SpinDown button the data which is selected in the database will change from those with date: 2012-08-21 15:31:00 to those with date 2012-08-21 10:10:00 So I think the date which we are currently on, should be stored in a variable. But on button hit not every bigger or lower data should be selected in the database, only those which are the closest bigger or the closest lower date. How can I do this? I hope I described my problem understandable. My native language is not english, so misunderstandings can occur! Please ask if you don't understand something! Thank you for reading!

  • XSLT multiple string replacement with recursion

    - by John Terry
    I have been attempting to perform multiple (different) string replacement with recursion and I have hit a roadblock. I have sucessfully gotten the first replacement to work, but the subsequent replacements never fire. I know this has to do with the recursion and how the with-param string is passed back into the call-template. I see my error and why the next xsl:when never fires, but I just cant seem to figure out exactly how to pass the complete modified string from the first xsl:when to the second xsl:when. Any help is greatly appreciated. <xsl:template name="replace"> <xsl:param name="string" select="." /> <xsl:choose> <xsl:when test="contains($string, '&#13;&#10;')"> <xsl:value-of select="substring-before($string, '&#13;&#10;')" /> <br/> <xsl:call-template name="replace"> <xsl:with-param name="string" select="substring-after($string, '&#13;&#10;')"/> </xsl:call-template> </xsl:when> <xsl:when test="contains($string, 'TXT')"> <xsl:value-of select="substring-before($string, '&#13;TXT')" /> <xsl:call-template name="replace"> <xsl:with-param name="string" select="substring-after($string, '&#13;')" /> </xsl:call-template> </xsl:when> <xsl:otherwise> <xsl:value-of select="$string"/> </xsl:otherwise> </xsl:choose> </xsl:template>

  • Django 404 page not showing up

    - by Matthew Doyle
    Hey all, I'm in the middle of putting up my first django application on shared hosting. This should be an easy thing, but I am just not seeing it. I tried to follow the directions of the django documentation, and created a 404.html page within my template folder. I just wrote "This is a 404 page." in the .html file. I also did the same thing for a 500.html page and wrote in it "This is a 500 page." However when I hit a 'bad page' I get a standard 404 page from the browser (Oops! This link appears to be broken. in Chrome) when I would expect "This is a 404 page." What's even more interesting is out of frustration I wrote {% asdfjasdf %} in the 404.html, and instead of getting the "Oops!..." error I get "This is a 500 page," so it definitely sees the 404.html template. Here's what I can confirm: Debug = False I am running apache on a shared hosting I have not done anything special with .htaccess and 404 errors. If I run with Debug = True, it says it's a 404 error. I am using FastCGI Anything else anyone think I could try? Thank you very much!

  • Asp.net Crawler Webresponse Operation Timed out.

    - by Leon
    Hi I have built a simple threadpool based web crawler within my web application. Its job is to crawl its own application space and build a Lucene index of every valid web page and their meta content. Here's the problem. When I run the crawler from a debug server instance of Visual Studio Express, and provide the starting instance as the IIS url, it works fine. However, when I do not provide the IIS instance and it takes its own url to start the crawl process(ie. crawling its own domain space), I get hit by operation timed out exception on the Webresponse statement. Could someone please guide me into what I should or should not be doing here? Here is my code for fetching the page. It is executed in the multithreaded environment. private static string GetWebText(string url) { string htmlText = ""; HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url); request.UserAgent = "My Crawler"; using (WebResponse response = request.GetResponse()) { using (Stream stream = response.GetResponseStream()) { using (StreamReader reader = new StreamReader(stream)) { htmlText = reader.ReadToEnd(); } } } return htmlText; } And the following is my stacktrace: at System.Net.HttpWebRequest.GetResponse() at CSharpCrawler.Crawler.GetWebText(String url) in c:\myAppDev\myApp\site\App_Code\CrawlerLibs\Crawler.cs:line 366 at CSharpCrawler.Crawler.CrawlPage(String url, List1 threadCityList) in c:\myAppDev\myApp\site\App_Code\CrawlerLibs\Crawler.cs:line 105 at CSharpCrawler.Crawler.CrawlSiteBuildIndex(String hostUrl, String urlToBeginSearchFrom, List1 threadCityList) in c:\myAppDev\myApp\site\App_Code\CrawlerLibs\Crawler.cs:line 89 at crawler_Default.threadedCrawlSiteBuildIndex(Object threadedCrawlerObj) in c:\myAppDev\myApp\site\crawler\Default.aspx.cs:line 108 at System.Threading.QueueUserWorkItemCallback.WaitCallback_Context(Object state) at System.Threading.ExecutionContext.runTryCode(Object userData) at System.Runtime.CompilerServices.RuntimeHelpers.ExecuteCodeWithGuaranteedCleanup(TryCode code, CleanupCode backoutCode, Object userData) at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state) at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean ignoreSyncCtx) at System.Threading.QueueUserWorkItemCallback.System.Threading.IThreadPoolWorkItem.ExecuteWorkItem() at System.Threading.ThreadPoolWorkQueue.Dispatch() at System.Threading._ThreadPoolWaitCallback.PerformWaitCallback() Thanks and cheers, Leon.

  • iphone-AVAudio Player Crashes

    - by user2779450
    I have an app that uses an avaudio player for two things. One of them is to play an explosion sound when a uiimageview collision is detected, and the other is to play a lazer sound when a button is pressed. I declared the audioplayer in the .h class, and I call it each time the button is clicked by doing this: NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"/lazer" ofType:@"mp3"]]; NSError *error; audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error]; if (error) { NSLog(@"Error in audioPlayer: %@", [error localizedDescription]); } else { [audioPlayer prepareToPlay]; } [audioPlayer play]; This works fine, but after many uses of the game, the audio will stop play when i hit the button, and when a collision is detected, the game crashes. Here is my crash log: 2013-09-18 18:09:19.618 BattleShip[506:907] 18:09:19.617 shm_open failed: "AppleAudioQueue.41.2619" (23) flags=0x2 errno=24 (lldb) Suggestions? Could there be something to do with repeatedly creating an audio player? Alternatives maybe?

  • applicationWillTerminate Appears to be Inconsistent

    - by Lauren Quantrell
    This one has me batty. In applicationWillTerminate I am doing two things: saving some settings to the app settings plist file and updating any changed data to the SQLite database referenced in the managedObjectContext. Problem is it works sometimes and not others. Same issue in the simulator and on the device. If I hit the home button while the app is running, I can only sometimes get the data to store in the plist and into the CoreData store. It seems that it's both works or neither works, and it makes no difference if I switch the execution order (saveState, managedObjectContext or managedObjectContext, saveState). I can't figure out how this can happen. Any help is greatly appreciated. lq AppDelegate.m @synthesize rootViewController; - (void)applicationWillTerminate:(UIApplication *)application { [rootViewController saveState]; NSError *error; if (managedObjectContext != nil) { if ([managedObjectContext hasChanges] && ![managedObjectContext save:&error]) { // Handle error exit(-1); // Fail } } } RootViewController.m - (void)saveState { NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults]; [userDefaults setInteger:self.someInteger forKey:kSomeNumber]; [userDefaults setObject:self.someArray forKey:kSomeArray]; }

  • Modify Executing Jar file

    - by pinkynobrain
    Hello Stack Overflow friends. I have a simple problem which i fear doesnt have a simple solution and i need advice as to how to proceed. I am developing a java application packaged as and executable JAR but it requires to modify some of its JAR file contents during execution. At this stage i hit a problem because some OS lock the file preventing writes to it. It is essential that the user sees an updated version of the jar file by the time the application exits allthough i can be pretty flexible as to how to achieve this. A clean and efficient solution is obviously prefereable but portability is the only hard requirement. The following are three approaches i can see to solving the problem, feel free to comment on them or suggest others. Tell Java to unlock the JAR file for writing(this doesnt seem possible but it would be the easyest solution) Copy the executable class files to a tempory file on application startup, use a class loader to load these files and unload the ones from the initial JAR file.(Not had much experience with the classloaders but hopefully the JVM would then be smart enough to realize that the original JAR is nolonger in use and so unlock it) Put a Second executable JAR File inside the First, on startup extract the inner jar to e temporaryfile, invoke a new java process and pass it the location of the Outer JAR, first process exits, second process modifys the Outer jar unincumbered.(This will work but im not sure there is a platform independant way of one java app invoking another) I know this is a weird question but any help would be appreciated.

  • Career Plan: The one year plan. The three year plan.

    - by drelihan
    Hi Folks, I work as a developer however I only recently began developing full time having worked for 5 years in various roles. When it comes to career planning I think I pretty much agree with The Journeyman to Craftsman model coined in The Pragmatic Probrammer and used by Bob Martin. I see myself as a journeyman and I won't call myself a "good" (for want of a better word) until I re-evaluate my skills in 5 years time. However, as part of our careers we are encouraged to make one and three year plan with specific goals that we should hit. Unfortunately, my goal is this: Write clean code that solves a problem and is easy to maintain. From a technology point of view I want to know C++ and .net programming inside out(C#, WCF etc..) But that's it. That's my plan. Is this enough? So although there's a great discussion on what people should do with their career: http://stackoverflow.com/questions/11313/career-planning-any-tips My question is this: What's your one year plan? What's your three year plan? And am I being naive with my career? Thanks,
