So I have an iphone app that presents a modal view when it starts if the user has not registered. Once they register, it saves a user ID into NSUserDefaults. When the app starts at a later time, it needs to load this user id in the appdelegate file. //Registration.m NSUserDefaults *savedUID = [NSUserDefaults standardUserDefaults]; [save...
I'm trying to save the contents of a textbox to a text file using Visual C#. I use the following code: private void savelog_Click(object sender, EventArgs e) { if (folderBrowserDialog3save.ShowDialog() == DialogResult.OK) { // create a writer and open the file TextWriter tw = new StreamWriter(...
In some sense, the default "save" operation appears to be asynchronous in MongoDB. It seems that when a client saves a document, it will typically receive a successful response immediately from the server, even if the operation has not yet been applied to the database (let alone committed to disk). (I'm basing this model for how save()...
Hi, I'm currently writing an Android game using surfaceView. I've optimized the game as much as possible and it runs quite smoothly. However, I have collision detection incorporated which is a bit messy. I would like to do collision detection by reading pixels directly from the canvas. Is this possible to do? The closest to this that I ...
Are model save() methods lazy in django? For instance, at what line in the following code sample will django hit the database? my_model = MyModel() my_model.name = 'Jeff Atwood' my_model.save() # Some code that is independent of my_model... model_id = model_instance.id print (model_id) ...
This happens to me all the time: I have a file open in emacs, I save it ('save-buffer), the file changes on disk (or get's deleted, moved, etc.) but I want it back, so I try to save again in emacs ('save-buffer) and instead of saving it says "(no changes need to be saved)" and does nothing. Is there a different function, or a setting...

From the official documentation I can't understand what is default parameter. obj, created = Person.objects.get_or_create(first_name='John', last_name='Lennon', defaults={'birthday': date(1940, 10, 9)} Does it mean that it will look for fields which match both John and Lennon parameter and birthday will just insert? ...
Hi all I'm trying to use NHibernate in a project. All my domain tables include a 'CreatedBy' field which is a foreign key to the Users table. Since this is an ASP.NET app, the only information I have about the user at the time of saving is the username, from the cookie. What is the best approach for obtaining the user ID and saving it ...
Hi all I'm overriding NHibernate's PreInsertEventListener in order to set the entity's DateCreated property to DateTime.Now. Here is my code: public bool OnPreInsert(PreInsertEvent e) { DomainObject domainObject = (DomainObject) e.Entity; if (domainObject.CreatedById == 0) throw new Exception("The " + domainObject.GetType().Name +...
Hi there, I'm in the middle of creating a Drupal site. It already has lots of content. This morning I found out that the "Save" button has now gone missing from my Page and News nodes. Users now have to click Preview before the Save button appears (both for creating new content and editing existing content). It was fine yesterday and I'...
We are implementing a system using EF4 and WPF. We are noticing an issue with the initial saving of data: when the initial SaveChanges is run there is a 4 to 6 second delay when context.SaveChanges() command is run. Every subsequent SaveChanges is very fast with no noticable delay. This is not a major issue - but an annoyance none-the-l...
My application uses NSUserDefaults to store some values so that it can restore them on application update or if backgrounding is quit. Backgrounding automatically saves my integer values, but if the user quits the application from the launcher, the numbers are lost too, and the ViewDidUnload method I guess doesn't evoke when entering bac...

I have a request to enable some links on a web page for PRINT and SAVE. Historically I've always avoided those as in the past they weren't supported in all browsers and OSes and, well, I also found them annoying as a user. I tended to opt for 'print friendly' functionality or, barring that, just proper print CSS. That said, I'm being a...
