• Custom annotationView images revert to pins when clicked

  - by Danny Tuppeny

  I'm displaying custom images on a map (instead of the default pins) using the code below. However, when I tap on an item (and the callout appears), the image reverts to the default red pin. How can I keep my custom image, even when the callout is displayed? - (MKAnnotationView *) mapView:(MKMapView *)map viewForAnnotation:(id <MKAnnotation>)annotation { MKPinAnnotationView *pinAnnotation = nil; if (annotation != mapView.userLocation) { static NSString *pinID = @"mapPin"; pinAnnotation = (MKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:pinID]; if (pinAnnotation == nil) pinAnnotation = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:pinID] autorelease]; // Set the image pinAnnotation.image = [UIImage imageNamed:@"TestIcon.png"]; // Set ability to show callout pinAnnotation.canShowCallout = YES; // Set up the disclosure button on the right side UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; pinAnnotation.rightCalloutAccessoryView = infoButton; [pinID release]; } return pinAnnotation; [pinAnnotation release]; }

• Error while configuring Sql server 2005 for full text search

• FileStream to save file then immediately unlock in C# ?

  - by aron

  Hello, I have this code that saves a pdf file. FileStream fs = new FileStream(SaveLocation, FileMode.Create); fs.Write(result.DocumentBytes, 0, result.DocumentBytes.Length); fs.Flush(); fs.Close(); It works fine. However sometimes it does not release the lock right away and that causes file locking exceptions with functions run after this one run. Is there a ideal way to release the file lock right after the fs.Close() thanks!

• How can I replace this semaphore with a monitor?

  - by Kurru

  Hi In previous question of mine, someone had meantioned that using Semaphores were expensive in C# compared to using a monitor. So I ask this, how can I replace the semaphore in this code with a monitor? I need function1 to return its value after function2 (in a separate thread) has been completed. I had replaced the Semaphore.WaitOne with a Monitor.Wait and the Semaphore.Release with a Monitor.PulseAll but the PulseAll was being triggered before the Wait causing the program to hang. Any idea how to avoid that race condition? Semaphore semaphore = new Semaphore(0,1); byte b; public byte Function1() { // new thread starting in Function2; semaphore.WaitOne(); return b; } public void Function2() { // do some thing b = 0; semaphore.Release(); }

• Crawling engine architecture - Java/ Perl integration

  - by Bigtwinz

  Hi all, I am looking to develop a management and administration solution around our webcrawling perl scripts. Basically, right now our scripts are saved in SVN and are manually kicked off by SysAdmin/devs etc. Everytime we need to retrieve data from new sources we have to create a ticket with business instructions and goals. As you can imagine, not an optimal solution. There are 3 consistent themes with this system: the retrieval of data has a "conceptual structure" for lack of a better phrase i.e. the retrieval of information follows a particular path we are only looking for very specific information so we dont have to really worry about extensive crawling for awhile (think thousands-tens of thousands of pages vs millions) crawls are url-based instead of site-based. As I enhance this alpha version to a more production-level beta I am looking to add automation and management of the retrieval of data. Additionally our other systems are Java (which I'm more proficient in) and I'd like to compartmentalize the perl aspects so we dont have to lean heavily on outside help. I've evaluated the usual suspects Nutch, Droid etc but the time spent on modifying those frameworks to suit our specific information retrieval cant be justified. So I'd like your thoughts regarding the following architecture. I want to create a solution which use Java as the interface for managing and execution of the perl scripts use Java for configuration and data access stick with perl for retrieval An example use case would be a data analyst delivers us a requirement for crawling perl developer creates the required script and uses this webapp to submit the script (which gets saved to the filesystem) the script gets kicked off from the webapp with specific parameters .... Webapp should be able to create multiple threads of the perl script to initiate multiple crawlers. So questions are what do you think how solid is integration between Java and Perl specifically from calling perl from java has someone used such a system which actually is part perl repository The goal really is to not have a whole bunch of unorganized perl scripts and put some management and organization on our information retrieval. Also, I know I can use perl do do the web part of what we want - but as I mentioned before - trying to keep perl focused. But it seems assbackwards I'm not adverse to making it an all perl solution. Open to any all suggestions and opinions. Thanks

• Application development using google applications?

  - by Ali

  Hi guys I'm developing a collaboration system and our team has been at it for the past couple of years. However the boss suggested that we try and redevelop it using something robust. Basically our collaboration system incorporates a webmail client and a custom built contacts management system plus project management system. My boss likes the robustness of GMAIL and Google docs and really would like a solution that if possible could incorporate these two and other google applications - I'm not so sure how to get started on developing a custom application using google applications - especially consider the fact that in the long run we wish to host our collaboration system as a paid service - just like the services that 37signals basecamp and highrise have been.

• Looking For a .NET Task Scheduling library

  - by Hounshell

  I'm looking for the following features: Scheduler uses SQL Server as the backing store Tasks can be scheduled by one application and executed by another I can have multiple applications, each of which handles a specific subset of tasks Tasks can be triggered at specific times, now, or based on the success or failure of other tasks Data can be attached to tasks There are a number of nice-to-have's, like a web management console, clustering/failover support, customizable logging, but they're not requirements. On the surface Quartz.NET has a nice interface and seems to fit the bill as it satisfies (1), (4 with some custom work) and (5), but I've been beating my head against (2) and (3) seems like I'd have to invest more effort than it's worth, especially given how convoluted the innards of it are. Any other libraries out there? Open source is preferred, with free as a close runner up. It's really hard to get management to pay for things like this when it's not their idea.

• Recommendations for keeping a build server updated

  - by gareth_bowles

  As a guy who frequently switches between QA, build and operations, I keep running into the issue of what to do about operating system updates on the build server. The dichotomy is the same on Windows, Linux, MacOS or any other o/s that can update itself via the internet: The QA team wants to keep the build server exactly as it is from the beginning of the product release cycle to the end, since installing updates could destabilize the server and means that successive builds aren't made against the same baseline. The ops team wants the software to be deployed on a system with all the latest security patches; this can mean that the software isn't deployed on exactly the same version of the o/s that it was built on. I usually mitigate this by taking release candidate builds and installing them on a test server that has a completely up-to-date o/s, repeating the automated tests that are run on the build server and doing some additional system level testing to make sure everything looks good before deployment. However, this seems inefficient to me; does anyone have a better way ?

• addSubview animation

  - by Mike

  I have main UIView where I display different data. Then I put a button, which displays subview like this: - (IBAction) buttonClicked: (id) sender { UIView *newView = [[UIView alloc] initWithFrame:CGRectMake(25,25,50,20)]; UILabel *newLabel = [[UILabel alloc] initWithFrame:CGRectMake(25,25, 50,25)]; newLabel.text = @"some text"; [newView addSubview: newLabel]; [self.view addSubview: newView]; [newLabel release]; [newView release]; } newView appears fine, but it doesn't animate itself any way, it just appears immediately. How can I add some kind of animation when newView appears? Like zoom or slide down or something like that. Is there some simple code?

• Images missing after moving Django to new server

  - by miszczu

  I'm moving Django project to new server. I'm newbie in Django, and I don't know where should be upload folder. There are all images which should be displayed on website. In config file I haven't seen upload folder I could specify, so I'm guessing it always should be the same location for django projects or I just can't find it. Locations are saved in database. When I've put uploaded files into media folder, so url was like domain.co.uk/media/upload/media/images/year/month/day/image_name.ext and the same is on the old website, images on website ware still missing. All images are visible if I put url by hand, but django doesn't seems to see files. Also I check django log file: 2012-05-30 09:13:33,393 ERROR render: Thumbnail tag failed: [in /usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/templatetags/thumbnail.py (line 49)] Traceback (most recent call last): File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/templatetags/thumbnail.py", line 45, in render return self._render(context) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/templatetags/thumbnail.py", line 97, in _render file_, geometry, **options File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/base.py", line 50, in get_thumbnail cached = default.kvstore.get(thumbnail) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/kvstores/base.py", line 25, in get return self._get(image_file.key) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/kvstores/base.py", line 123, in _get value = self._get_raw(add_prefix(key, identity)) File "/usr/lib/python2.6/site-packages/sorl_thumbnail-11.12-py2.6.egg/sorl/thumbnail/kvstores/cached_db_kvstore.py", line 26, in _get_raw value = KVStoreModel.objects.get(key=key).value File "/usr/lib/python2.6/site-packages/django/db/models/manager.py", line 132, in get return self.get_query_set().get(*args, **kwargs) File "/usr/lib/python2.6/site-packages/django/db/models/query.py", line 344, in get num = len(clone) File "/usr/lib/python2.6/site-packages/django/db/models/query.py", line 82, in __len__ self._result_cache = list(self.iterator()) File "/usr/lib/python2.6/site-packages/django/db/models/query.py", line 273, in iterator for row in compiler.results_iter(): File "/usr/lib/python2.6/site-packages/django/db/models/sql/compiler.py", line 680, in results_iter for rows in self.execute_sql(MULTI): File "/usr/lib/python2.6/site-packages/django/db/models/sql/compiler.py", line 735, in execute_sql cursor.execute(sql, params) File "/usr/lib/python2.6/site-packages/django/db/backends/util.py", line 34, in execute return self.cursor.execute(sql, params) File "/usr/lib/python2.6/site-packages/django/db/backends/mysql/base.py", line 86, in execute return self.cursor.execute(query, args) File "/usr/lib64/python2.6/site-packages/MySQLdb/cursors.py", line 174, in execute self.errorhandler(self, exc, value) File "/usr/lib64/python2.6/site-packages/MySQLdb/connections.py", line 36, in defaulterrorhandler raise errorclass, errorvalue DatabaseError: (1146, "Table 'thumbnail_kvstore' doesn't exist") 2012-05-30 09:13:33,396 DEBUG execute: (0.000) SELECT `freetext_freetext`.`id`, `freetext_freetext`.`key`, `freetext_freetext`.`content`, `freetext_freetext`.`active` FROM `freetext_freetext` WHERE (`freetext_freetext`.`active` = True AND `freetext_freetext`.`key` = office-closed-message ); args=(True, u'office-closed-message') [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] 2012-05-30 09:13:33,399 DEBUG execute: (0.000) SELECT `menus_menu`.`id`, `menus_menu`.`name`, `menus_menu`.`slug`, `menus_menu`.`base_url`, `menus_menu`.`description`, `menus_menu`.`enabled` FROM `menus_menu` WHERE (`menus_menu`.`enabled` = True AND `menus_menu`.`slug` = about ); args=(True, u'about') [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] 2012-05-30 09:13:33,401 DEBUG execute: (0.000) SELECT `menus_menuitem`.`id`, `menus_menuitem`.`menu_id`, `menus_menuitem`.`title`, `menus_menuitem`.`url`, `menus_menuitem`.`order` FROM `menus_menuitem` INNER JOIN `menus_menu` ON (`menus_menuitem`.`menu_id` = `menus_menu`.`id`) WHERE `menus_menu`.`slug` = about ORDER BY `menus_menuitem`.`order` ASC; args=(u'about',) [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] 2012-05-30 09:13:33,404 DEBUG execute: (0.000) SELECT `freetext_freetext`.`id`, `freetext_freetext`.`key`, `freetext_freetext`.`content`, `freetext_freetext`.`active` FROM `freetext_freetext` WHERE (`freetext_freetext`.`active` = True AND `freetext_freetext`.`key` = contactdetails-footer ); args=(True, u'contactdetails-footer') [in /usr/lib/python2.6/site-packages/django/db/backends/util.py (line 44)] I checked database and there is no table calls thumbnail_kvstore, but I have database backup, and in backup files this table doesn't exist.

• Iphone: UIWebview and double taps

  - by Eyal

  I would like to trap a double tap event in a UIWebView. I have derived a class from UIWebController. When I double tap it seams that the UIWebController itself is responding to my double taps instead of my class. The weird thing is that when I change the inheritance to inherit from UIView everything works just fine. Below are snippets from my code which is supposed to invoke a pop-up when double tapped. In the init function: //Setup action for double tap UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleDoubleTap:)]; tap.numberOfTapsRequired = 2; [super addGestureRecognizer:tap]; [tap release]; And Also: - (void)handleDoubleTap:(UIGestureRecognizer *)gestureRecognizer { UIAlertView *someError = [[UIAlertView alloc] initWithTitle: @"Network error" message: @"Hello" delegate: self cancelButtonTitle: @"Ok" otherButtonTitles: nil]; [someError show]; [someError release]; //[[NSNotificationCenter defaultCenter] postNotificationName:NOTIFICATION_FLIP_TO_PAGE_VIEW object:nil]; }

• pushViewController using UINavigationItem instead of UINavigationController

  Hello, I have implemented a method didSelectRowAtIndexPath that should push another view. I have a code running properly using a navigationController but in this case I am using a navigationItem on a view. How could I trigger a view?

• Is this a good way to do a game loop for an iPhone game?

  - by Danny Tuppeny

  Hi all, I'm new to iPhone dev, but trying to build a 2D game. I was following a book, but the game loop it created basically said: function gameLoop update() render() sleep(1/30th second) gameLoop The reasoning was that this would run at 30fps. However, this seemed a little mental, because if my frame took 1/30th second, then it would run at 15fps (since it'll spend as much time sleeping as updating). So, I did some digging and found the CADisplayLink class which would sync calls to my gameLoop function to the refresh rate (or a fraction of it). I can't find many samples of it, so I'm posting here for a code review :-) It seems to work as expected, and it includes passing the elapsed (frame) time into the Update method so my logic can be framerate-independant (however I can't actually find in the docs what CADisplayLink would do if my frame took more than its allowed time to run - I'm hoping it just does its best to catch up, and doesn't crash!). // // GameAppDelegate.m // // Created by Danny Tuppeny on 10/03/2010. // Copyright Danny Tuppeny 2010.

Bonus points if you can tell me why all the books use "viewController.view" but for everything else seem to use "[object name]" format. Why not [viewController view]?

• What Is The Best Database For Delphi Desktop Applications That Supports Stored Procedures?

  - by Cape Cod Gunny

  I started with Turbo Pascal 3, went to TP5, Bought TP6 called Borland the next day and downgraded to TP5.5. Bought Delphi 3, and now have Delphi 5 Enterprise. I sort of lost interest in writing code about 4-5 years ago for two reasons; Spent all day writing ASP & SQL for someone else. PC Techniques magazine went away. I've got a few programs in the shareware market that are solid performers but are in need of serious updating. I love Delphi or did when it was Borland (before Borland bought DBase and all the other crap), I'd like to salvage as much of my D5E code as possible but I doubt I can. I plan on upgrading to Delphi 2010. My next software release needs to interact with a database. I'm very proficient with MS Sql and like to put all of the database code in stored procedures. What is the best database choice that interacts well with Delphi, allows stored procedures and is so easy to deploy that even the Geico gecko could deploy it? 10/25/2009 18:53 PM EST Re-Opened After Reading Install Docs for Delphi 2010 I downloaded a trial version of Delphi 2010 and unzipped the install. I've been reading the install docs included in the package. I started with the install.htm inside the zip package. install.htm wisely tells you to see the following two articles: Installation Notes: http://edn.embarcadero.com/article/39754 Release Notes: http://edn.embarcadero.com/article/39758 the release notes state the following... MSSQL driver requires the installation of the SQL Native Client. SQL Native Client 2008 is required for dbxmss.dll. SQL Native Client 2005 is required for dbxmss9.dll I checked my machine to see if SQL Native Client is installed. Nope. I wasn't done reading the docs so I made a note to install SQL Native Client. I googled dbxmss.dll and dbxmss9.dll and found a very interesting thread on the Embarcadero forums. read thread here. After reading this thread and some careful thought I don't think I will be using Microsoft SQL Express. I can't rely on my customers having the right drivers installed. So, I'm back to looking for a different solution. If I'm selling a $40 product to the general masses I need to have a bulletproof solution that doesn't require my brand new customer to update their machine before my software will work.

• MySQL Binary Storage using BLOB VS OS File System: large files, large quantities, large problems.

  - by Quantico773

  Hi Guys, Versions I am running (basically latest of everything): PHP: 5.3.1 MySQL: 5.1.41 Apache: 2.2.14 OS: CentOS (latest) Here is the situation. I have thousands of very important documents, ranging from customer contracts to voice signatures (recordings of customer authorisation for contracts), with file types including, but not limited to jpg, gif, png, tiff, doc, docx, xls, wav, mp3, pdf, etc. All of these documents are currently stored on several servers including Windows 32 bit, CentOS and Mac, among others. Some files are also stored on employees desktop computers and laptops, and some are still hard copies stored in hundreds of boxes and filing cabinets. Now because customers or lawyers could demand evidence of contracts at any time, my company has to be able to search and locate the correct document(s) effectively, for this reason ALL of these files have to be digitised (if not already) and correlated into some sort of order for searching and accessing. As the programmer, I have created a full Customer Relations Management tool that the whole company uses. This includes Customer Profiles management, Order and job Tracking tools, Job/sale creation and management modules, etc, and at the moment any file that is needed at a customer profile level (drivers licence, credit authority, etc) or at a job/sale level (contracts, voice signatures, etc) can be uploaded to the server and sits in a parent/child hierarchy structure, just like Windows Explorer or any other typical file managment model. The structure appears as such: drivers_license |- DL_123.jpg voice_signatures |- VS_123.wav |- VS_4567.wav contracts So the files are uplaoded using PHP and Apache, and are stored in the file system of the OS. At the time of uploading, certain information about the file(s) is stored in a MySQL database. Some of the information stored is: TABLE: FileUploads FileID CustomerID (the customer id that the file belongs to, they all have this.) JobID/SaleID (the id of the job/sale associated, if any.) FileSize FileType UploadedDateTime UploadedBy FilePath (the directory path the file is stored in.) FileName (current file name of uploaded file, combination of CustomerID and JobID/SaleID if applicable.) FileDescription OriginalFileName (original name of the source file when uploaded, including extension.) So as you can see, the file is linked to the database by the File Name. When I want to provide a customers' files for download to a user all I have to do is "SELECT * FROM FileUploads WHERE CustomerID = 123 OR JobID = 2345;" and this will output all the file details I require, and with the FilePath and FileName I can provide the link for download. http... server / FilePath / FileName There are a number of problems with this method: Storing files in this "database unconcious" environment means data integrity is not kept. If a record is deleted, the file may not be deleted also, or vice versa. Files are strewn all over the place, different servers, computers, etc. The file name is the ONLY thing matching the binary to the database and customer profile and customer records. etc, etc. There are so many reasons, some of which are described here: http://www.dreamwerx.net/site/article01 . Also there is an interesting article here too: sietch.net/ViewNewsItem.aspx?NewsItemID=124 . SO, after much research I have pretty much decided I am going to store ALL of these files in the database, as a BLOB or LONGBLOB, but there are still many considerations before I do this. I know that storing them in the database is a viable option, however there are a number of methods of storing them. I also know storing them is one thing; correlating and accessing them in a manageable way is another thing entirely. The article provided at this link: dreamwerx.net/site/article01 describes a way of splitting the uploaded binary files into 64kb chunks and storing each chunk with the FileID, and then streaming the actual binary file to the client using headers. This is a really cool idea since it alleviates preassure on the servers memory; instead of loading an entire 100mb file into the RAM and then sending it to the client, it is doing it 64kb at a time. I have tried this (and updated his scripts) and this is totally successful, in a very small frame of testing. So if you are in agreeance that this method is a viable, stable and robust long-term option to store moderately large files (1kb to couple hundred megs), and large quantities of these files, let me know what other considerations or ideas you have. Also, I am considering getting a current "File Management" PHP script that gives an interface for managing files stored in the File System and converting it to manage files stored in the database. If there is already any software out there that does this, please let me know. I guess there are many questions I could ask, and all the information is up there ^^ so please, discuss all aspects of this and we can pass ideas back and forth and teach each other. Cheers, Quantico773

• Django: CharField with fixed length, how?

  - by Giovanni Di Milia

  Hi everybody, I wold like to have in my model a CharField with fixed length. In other words I want that only a specified length is valid. I tried to do something like volumenumber = models.CharField('Volume Number', max_length=4, min_length=4) but it gives me an error (it seems that I can use both max_length and min_length at the same time). Is there another quick way? Thanks EDIT: Following the suggestions of some people I will be a bit more specific: My model is this: class Volume(models.Model): vid = models.AutoField(primary_key=True) jid = models.ForeignKey(Journals, db_column='jid', null=True, verbose_name = "Journal") volumenumber = models.CharField('Volume Number') date_publication = models.CharField('Date of Publication', max_length=6, blank=True) class Meta: db_table = u'volume' verbose_name = "Volume" ordering = ['jid', 'volumenumber'] unique_together = ('jid', 'volumenumber') def __unicode__(self): return (str(self.jid) + ' - ' + str(self.volumenumber)) What I want is that the volumenumber must be exactly 4 characters. I.E. if someone insert '4b' django gives an error because it expects a string of 4 characters. So I tried with volumenumber = models.CharField('Volume Number', max_length=4, min_length=4) but it gives me this error: Validating models... Unhandled exception in thread started by <function inner_run at 0x70feb0> Traceback (most recent call last): File "/Library/Python/2.5/site-packages/django/core/management/commands/runserver.py", line 48, in inner_run self.validate(display_num_errors=True) File "/Library/Python/2.5/site-packages/django/core/management/base.py", line 249, in validate num_errors = get_validation_errors(s, app) File "/Library/Python/2.5/site-packages/django/core/management/validation.py", line 28, in get_validation_errors for (app_name, error) in get_app_errors().items(): File "/Library/Python/2.5/site-packages/django/db/models/loading.py", line 131, in get_app_errors self._populate() File "/Library/Python/2.5/site-packages/django/db/models/loading.py", line 58, in _populate self.load_app(app_name, True) File "/Library/Python/2.5/site-packages/django/db/models/loading.py", line 74, in load_app models = import_module('.models', app_name) File "/Library/Python/2.5/site-packages/django/utils/importlib.py", line 35, in import_module __import__(name) File "/Users/Giovanni/src/djangoTestSite/../djangoTestSite/journaldb/models.py", line 120, in <module> class Volume(models.Model): File "/Users/Giovanni/src/djangoTestSite/../djangoTestSite/journaldb/models.py", line 123, in Volume volumenumber = models.CharField('Volume Number', max_length=4, min_length=4) TypeError: __init__() got an unexpected keyword argument 'min_length' That obviously doesn't appear if I use only "max_length" OR "min_length". I read the documentation on the django web site and it seems that I'm right (I cannot use both together) so I'm asking if there is another way to solve the problem. Thanks again

• Unlocking SVN working copy with unversioned resources

  - by Vijay Dev

  I have a repository which contains some unversioned directories and files. The server running svn was recently changed and since the checkout was done using the url svn://OLD-IP, I relocated my svn working copy, this time to the url svn://NEW-DOMAIN-NAME. Now since there are some unversioned resources, the switch did not happen properly and the working copy got locked. A cleanup operation did not work either because of these unversioned resources. I looked up in the net and found about svn ignore and tried that but to no use. I am unable to release all locks. Any ideas on solving the problem? Once I release the locks, I believe I can use svn ignore and carry on the relocate operation.

• odd problem with jni interacting with dll's - not sure why a change to gc ergonomics fixes it

  - by jim hale

  We were having a problem with our Tomcat jvm blowing up and giving us an hs_* dump at random times but always in the same spot, that wasn't very informative other than saying we had an EXCEPTION_ACCESS_VIOLATION Commenting out various parts of the java that called particular jni functions just made it blow consistently in another spot. By changing our jvm options from: set PAF_OPTS=-Xms1024m -Xmx32000m -server -XX:+UseParallelGC -XX:+UseParallelOldGC -XX:+DisableExplicitGC -XX:+UseCompressedOops -Djava.library.path="%CATALINA_HOME%"\jni -Dcom.sun.management.jmxremote TO set PAF_OPTS=-Xms1024m -Xmx32000m -server -XX:+DisableExplicitGC -XX:+UseCompressedOops -Djava.library.path="%CATALINA_HOME%"\jni -Dcom.sun.management.jmxremote The problem went away. The solution does not give me a warm and fuzzy however and am wondering anyone might understand what's going on under the covers here. Environment: jdk1.6, 64 bit OS and Java, Tomcat, Windows

• NSInvalidArgumentException: Illegal attempt to establish a relationship between objects in different

  - by iPhoneDollaraire

  I have an app based on the CoreDataBooks example that uses an addingManagedObjectContext to add an Ingredient to a Cocktail in order to undo the entire add. The CocktailsDetailViewController in turn calls a BrandPickerViewController to (optionally) set a brand name for a given ingredient. Cocktail, Ingredient and Brand are all NSManagedObjects. Cocktail requires at least one Ingredient (baseLiquor) to be set, so I create it when the Cocktail is created. If I add the Cocktail in CocktailsAddViewController : CocktailsDetailViewController (merging into the Cocktail managed object context on save) without setting baseLiquor.brand, then it works to set the Brand from a picker (also stored in the Cocktails managed context) later from the CocktailsDetailViewController. However, if I try to set baseLiquor.brand in CocktailsAddViewController, I get: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Illegal attempt to establish a relationship 'brand' between objects in different contexts' From this question I understand that the issue is that Brand is stored in the app's managedObjectContext and the newly added Ingredient and Cocktail are stored in addingManagedObjectContext, and that passing the ObjectID instead would avoid the crash. What I don't get is how to implement the picker generically so that all of the Ingredients (baseLiquor, mixer, garnish, etc.) can be set during the add, as well as one-by-one from the CocktailsDetailViewController after the Cocktail has been created. In other words, following the CoreDataBooks example, where and when would the ObjectID be turned into the NSManagedObject from the parent MOC in both add and edit cases? -IPD UPDATE - Here's the code: - (IBAction)addCocktail:(id)sender { CocktailsAddViewController *addViewController = [[CocktailsAddViewController alloc] init]; addViewController.title = @"Add Cocktail"; addViewController.delegate = self; // Create a new managed object context for the new book -- set its persistent store coordinator to the same as that from the fetched results controller's context. NSManagedObjectContext *addingContext = [[NSManagedObjectContext alloc] init]; self.addingManagedObjectContext = addingContext; [addingContext release]; [addingManagedObjectContext setPersistentStoreCoordinator:[[fetchedResultsController managedObjectContext] persistentStoreCoordinator]]; Cocktail *newCocktail = (Cocktail *)[NSEntityDescription insertNewObjectForEntityForName:@"Cocktail" inManagedObjectContext:self.addingManagedObjectContext]; newCocktail.baseLiquor = (Ingredient *)[NSEntityDescription insertNewObjectForEntityForName:@"Ingredient" inManagedObjectContext:self.addingManagedObjectContext]; newCocktail.mixer = (Ingredient *)[NSEntityDescription insertNewObjectForEntityForName:@"Ingredient" inManagedObjectContext:self.addingManagedObjectContext]; newCocktail.volume = [NSNumber numberWithInt:0]; addViewController.cocktail = newCocktail; UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:addViewController]; [self.navigationController presentModalViewController:navController animated:YES]; [addViewController release]; [navController release]; }

• Accessing Content from MDF after attached to SQL

  - by Fidelis

  Hello, I am using WSS 3.0 and trying to restore a mdf. I attached the database in SQL Management Studio, created a new web application, and associated the database to it. When I go into Central Administration- Application Management - Content Databases I see the WSS_Content and it says Sites: 2. One of the sites looks more similar to the other. I was able to log into the Sharepoint web app that has the db attached to it, and while it gives me the basic structure of the backed up site, the content of lists is blank, that was the data I was really after (Announcements, tasks, etc exist as lists but are empty). How do I get access to this?

• Using PostRequestHandlerExecute, Flush and Close to clean up after a request - why is this bad?

  - by Erwin

  After some requests I need to clean up after the user - by calling a remote web service to release some resources if I guess the user doesn't need them anymore. It is ok to leave them hanging and letting them time out on the other server, but the polite thing to do is to inform it that I do not need them anymore. I do not want to waste the users time waiting for cleaning - so I tried to find place to put it. First I tried Application_EndRequest, but I needed something later. Then I found PostRequestHandlerExecute which seemed like a nice place, but I still need a Flush and Close to release the connection to the user. Protected Sub Application_PostRequestHandlerExecute(ByVal sender As Object, ByVal e As System.EventArgs) Response.Flush() Response.Close() ' Simulation of clean up activity: System.Threading.Thread.Sleep(4000) ' Really a couple of web service calls End Sub Is there some other place I could put these lengthy clean up routines?
