  • '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?

  • Detecting death of spawned process using Window CRT

    - by Michael Tiller
    Executive summary: I need a way to determine whether a Windows process I've spawned via _spawnl and am communicating with using FDs from _pipe has died. Details: I'm using the low-level CRT function in Windows (_eof, _read) to communicate with a process that was spawned via a call to _spawnl (with the P_NOWAIT) flag. I'm using _pipe to create file descriptors to communicate with this spawned process and passing those descriptors (the FD #) to it on the command line. It is worth mentioning that I don't control the spawned process. It's a black box to me. It turns out that the process we are spawning occasionally crashes. I'm trying to make my code robust to this by detecting the crash. Unfortunately, I can't see a way to do this. It seems reasonable to me to expect that a call to _eof or _read on one of those descriptors would return an error status (-1) if the process had died. Unfortunately, that isn't the case. It appears that the descriptors have a life of their own independent of the spawned process. So even though the process on the other end is dead, I get no error status on the file descriptor I'm using to communicate with it. I've got the PID for the nested process (returned from the _spanwnl call) but I don't see anything I can do with that. My code works really well except for one thing. I can't detect whether the spawned process is simply busy computing me an answer or has died. If I can use the information from _pipe and _spawnl to determine if the spawned process is dead, I'll be golden. Suggestions very welcome. Thanks in advance. UPDATE: I found a fairly simple solution and added it as the selected answer.

  • 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?

  • 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?

  • Template with constant expression: error C2975 with VC++2008

    - by Arman
    Hello, I am trying to use elements of meta programming, but hit the wall with the first trial.

  • "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.

  • Calculating bounding grid coordinates to a user click on google maps/google earth

    - by user170304
    Hello, I have a requirement to calculate the centroid or geodesic midpoint of when a user clicks in between the lat/long grid crossing. The crossing forms a square in most parts of GE and sometimes elongated rectangles. This is due to the shape of the earth of course. I'm looking for a valid mathematical formula that would allow a user to click anywhere in between this grid and then an accurate function (in Javascript or server side code) that would take an assumed grid resolution (say 1km intervals for this discussion) and the input coordinates that should return a centroid coordinate within that graticule grid. To clarify please take a look at the attached image to my google group post: http://google-earth-api.googlegroups.com/web/Picture+5.png?gda=h5oFPz8AAAD315KpovipQeBwdfGpmW3ZhBc9PTADwYa-n193hZ6AItFmHuno63c7phcEXYVuRA6ccyFKn-rNKC-d1pM%5FIdV0&gsc=sz6bbAsAAABBKF7YXWYyc4GmXg-QruHj What I need to be able to do is if a user clicks anywhere in this grid square, I need to find the centroid or center point of that grid intersection/square or at least the bounding grid coordinates (that make the square). If we assume that the grid is UTM standard and has a max resolution of 1km (or make this a parameter), I need to detect the four other points nearby and then calculating the centroid is not as difficult. I welcome any feedback you all may have and appreciate it. I don't have a simple way of letting a user click anywhere on the grid and finding the grid bounding coordinates (making a square of 4 coordinates) or the centroid / midpoint of the graticule grid square necessary. One thought is to use assumptions as much as possible using a reference such as UTM coordinate reference. If I assume that the grid is X degrees wide, can we have a pure javascript function take any input coordinate and return for me the bounding graticule coordinates in Decimal Degrees? Another thought I had was to create the grid in a geo-spatial layer to take any input coordinate and return the nearest centroid of the graticule? Does this make sense? Thanks! Omar

  • (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!

  • Javascript/PHP and timezones

    - by James
    Hi, I'd like to be able to guess the user's timezone offset and whether or not daylight savings is being applied. Currently, the most definitive code that I've found for this is here: http://www.michaelapproved.com/articles/daylight-saving-time-dst-detect/ So this gives me the offset along with the DST indicator. Now, I want to use these in my PHP scripts in order to ouput the local date/time for the user....but what's best for this? I figure I have 2 options: a) Pick a random timezone which has the same offset and DST setting from the output of timezone_abbreviations_list(). Then call date_timezone_set() with this in order to apply the correct treatment to the time. b) Continue treating the date as UTC but just do some timestamp addition to add the appropriate number of hours on. My feeling is that option B is the best way. The reason for this is that with A, I could be using a timezone which although correct in terms of offset/dst, may have some obscur rules in place behind the scene that could give surprising results (I don't know of any but nonetheless I don't think I can rule it out). I'd then re-check the timezone using Javascript at the start of each session in order to capture when either the user's timezone changes (very unlikely) or they pass in to the DST period. Sorry for the brain dump - I'm really just after some sort of reassurance that the approaches above are valid. Thanks, James.

  • 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>

  • 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]; }

  • 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!

  • Unit testing with Mocks when SUT is leveraging Task Parallel Libaray

    - by StevenH
    I am trying to unit test / verify that a method is being called on a dependency, by the system under test. The depenedency is IFoo. The dependent class is IBar. IBar is implemented as Bar. Bar will call Start() on IFoo in a new (System.Threading.Tasks.)Task, when Start() is called on Bar instance. Unit Test (Moq): [Test] public void StartBar_ShouldCallStartOnAllFoo_WhenFoosExist() { //ARRANGE //Create a foo, and setup expectation var mockFoo0 = new Mock<IFoo>(); mockFoo0.Setup(foo => foo.Start()); var mockFoo1 = new Mock<IFoo>(); mockFoo1.Setup(foo => foo.Start()); //Add mockobjects to a collection var foos = new List<IFoo> { mockFoo0.Object, mockFoo1.Object }; IBar sutBar = new Bar(foos); //ACT sutBar.Start(); //Should call mockFoo.Start() //ASSERT mockFoo0.VerifyAll(); mockFoo1.VerifyAll(); } Implementation of IBar as Bar: class Bar : IBar { private IEnumerable<IFoo> Foos { get; set; } public Bar(IEnumerable<IFoo> foos) { Foos = foos; } public void Start() { foreach(var foo in Foos) { Task.Factory.StartNew( () => { foo.Start(); }); } } } I appears that the issue is obviously due to the fact that the call to "foo.Start()" is taking place on another thread (/task), and the mock (Moq framework) can't detect it. But I could be wrong. Thanks

  • 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.

  • Dynamic Table CheckBoxes not having a "Checked" true value

    - by LuvlyOvipositor
    I have been working on a web app using ASP.NET with the code base as C#. I have a dynamic table that resizes based on a return from a SQL query; with a check box added in the third cell of each row. The checkbox is assigned an ID according to an index and the date. When users hit the submit button, the code is supposed to get a value from each row that is checked. However, when looping through the rows, none of the check boxes ever have a value of true for the Checked property. The ID persists, but the value of the checkbox seems to be lost. Code for adding the Checkboxes: cell = new TableCell(); CheckBox cb = new CheckBox(); cell.ApplyStyle(TS); cb.ID = index.ToString() + " " + lstDate.SelectedItem.Text.ToString(); if (reader["RestartStatus"].ToString() == "0") { cb.Checked = false; cb.Enabled = true; } else { cb.Checked = true; } cell.Controls.Add(cb); The code for getting the checkbox value: for (int i = 0; i < CompTable.Rows.Count; i++) { int t3 = CompTable.Rows[i].Cells[2].Controls.Count; Control temp = null; if (t3 0) { temp = CompTable.Rows[i].Cells[2].Controls[0]; } string t2 = i.ToString() + " " + lstDate.SelectedItem.Text.ToString(); if ( temp != null && ((CheckBox)temp).ID == i.ToString() + " " + lstDate.SelectedItem.Text.ToString()) { //Separated into 2 if statements for debugging purposes //ID is correct, but .Checked is always false (even if all of the boxes are checked) if (((CheckBox)temp).Checked == true) { tlist.Add(CompTable.Rows[i].Cells[0].Text.ToString()); } } }

  • 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,

  • ASP.NET MVC2 DataAnnotations not catching error

    - by Paul Connolly
    Can somebody help me to figure out why DataAnnotations will not work with my MVC2 project in VS 2008 SP1? Here's the situation.. I uninstalled VS2008 and MVC1, then reinstalled VS2008 SP1 and .NET 3.5 SP1 and MVC2. Now when I create a clean project as soon as it has to hit the DataAnnotations Dll (e.g. say when I go to Register.aspx it fails at the first "LabelFor" that it encounters. I can overcome this by changing the "Copy Local" property of the dll to True but this then creates a conflict with the same dll in the Tests project. If then I delete the test project and try agan, it runs but does not catch any validation failures. I have gone right back to basics and followed the step by step ScottGu Datavalidation tutorial at : http://weblogs.asp.net/scottgu/archive/2010/01/15/asp-net-mvc-2-model-validation.aspx And at the "Et viola" bit where we usually go "Whoa! cool!" I say "It never caught!". Any Ideas?

  • PoptorootViewController fails then removes all Viewcontrollers

    - by Spyker
    Trying to fix a very strange error, i have 3 view controllers that start from the app delegate and push each other accordingly. The 3rd view controller then has a toolbar button that calls the code here: -(void)showEventBrowser; { accelManeger.delegate = nil; NSLog(@"%u",[self.navigationController.viewControllers count]); [self.navigationController popToRootViewControllerAnimated:NO]; } This works the first time round but when i come back to this view controller and try again. Firstly it reports that there are 3 view controllers on the stack. It then deallocs the 2nd view controller in the stack and doesnt crash but will not go any further. If i hit the button again it says there are no view controllers on the stack and fails to respond. I have logs for all the viewdid, viewwill, e.t.c in each view controller and there appears to be no odd behaviour. Also no memory warnings from any view controllers. Why would this work once through but not the second time ?

  • JConsole does not connect when a program is waiting for a console input

    - by Calm Storm
    Hi, I have a problem similar to the one mentioned here. I have a program which launches a selenium browser and refreshes it every 2 seconds. My idea here was to monitor the memory usage of my application as the page is being hit. This console program does a "System.in.read" and when a user presses enter key, this stops the browser refresh thread. I run the program and it runs as I would expect it to. But when I fire jconsole and attach it to the process, it looks like jconsole waits forever to attach. This is because of the "System.in.read", apparently as shown in the JConsole source. In my code it makes perfect sense for me to terminte the browser when user presses something so is there any alternative available at all ? (Posted code sample below) package com.ekanathk; import java.util.ArrayList; import java.util.List; import org.junit.Test; public class MultiThread { @Test public void testSimple() throws Exception { List<Integer> x = new ArrayList<Integer>(); for(int i = 0; i < 1000; i++) { x.add(i); } System.out.print("Press Enter to stop (try attach a jconsole now...."); System.in.read(); } } The problem here seems to be that any System.in.read (either in Main thread or any threads) seems to completely block jconsole. I guess the problem essentially boils down to multiple threads requesting system inputs at the same time? Is there a solution ?

  • How do you update table row background color in IE using Javascript/CSS ?

    - by giulio
    I have a table that i want to "highlight" during onmouseover/onmouseout. I already know this is required in IE but not in other browsers. I have managed to detect the events triggering and this TR tag effectively works. (Note that the originating class "contentTableRow" doesn't seem to be causing any issues.) class="contentTableRow" onclick="openForm('SomeID');" onmouseover="highlight('someRowID', true);" onmouseout="highlight('someRowID', false);" id="someRowID" All is fine and dandy, the "highlight" function fires and actually sets the appropriate class. It's just that IE won't process the CSS class name change. Here is a snippet of the CSS I am using to make the change. .HighlightOn { cursor:pointer; background-color: #D1DFFF; } .HighlightOff { background-color: #E1EEFE; } I can see that the Class names are getting updated when I debug it, and also check it in Firebug. But it seems that IE doesn't like this usage of classes with a TR tag.. Is it the way I am structuring the class for Tables ? Any advice ?
