It seems to me that I have to retrieve an object before I delete it with entity framework like below
var customer = context.Customers.First(c => c.Id = 1);
context.DeleteObject(customer);
context.Savechanges();
So I need to hit database twice. Is there a easier way?
Thanks
In the dealloc method for a class how would I print out the ID (or some other unique identifier) for the instance being deallocated?
- (void)dealloc {
NSLog(@"_deallocing: ??");
[super dealloc];
}
Is this possible? I am just trying to get a little more feedback in the console as an aid to learning.
many thanks -gary-

Hello guys, I've made an application that makes full use of ajax, and what I need to do is:
I want a button with a description + image that when clicked is disabled and instead of the original image in the button, appears the ajax loading element id inside the button. And when the ajax loading is complete, the original image of the button returns to the normal.
Is there any good source on how to do something like this?
What do you guys suggest?

I'm looking for same way to get an unique ID of every partition in Win OS.
Also for flash drives (SD cards, pendrives, etc.) connected to PC.
I think that after formatting they get an unique ID - like MAC, right?
Also I want to get other information of that partition - it's name, file system, size, etc.
Due to target audience I am using .net cookieless sessions in auto-detect mode and time to time I get visitors redirected with cookiless session url like
domain.com/(S(jdhdghdghd))/default.aspx
Problem is, if I call this url after session expired .net will re-create it. What I want to find out is a way to force .net to create another session id instead of using the one that came with url.
Is it possible?
I'm developing an application with javascript. What I need is to have divs with id's (1,2,3...) and be able to insert a div between, for example, 2 and 3, with jquery, and then have that be the new three, and three becomes four, four becomes five, etc. I've got the div insertion working, I just need to know how to reorder the divs. Any ideas?
I'm trying link 40 buttons to one event handler method and then do the
processing work from one method instead of 40. I know how to link it
but once I get there I don't know how to distinguish what button was
pressed. Does anyone know how to reference the button object sender id
or is there another way to solve this problem?
Any help would be greatly appreciated.
I am trying to use the following code, but I always get an error that I can find little information about:
- (id)initWithNibName:@"MyRidesListView" bundle:nil {
if ((self = [super initWithNibName:@"MyRidesListView" bundle:nil])) {
// Custom initialization
}
return self;
}
Error:
expected identifier before 'OBJC_STRING' token
This seems like a simple method to be calling. This is for a UINavigationController.
Ideas?

Hello,
Using rails3 new routing system, is it possible to change the default :id parameter
resources :users, :key => :username
come out with the following routes
/users/new
/users/:username
/users/:username/edit
...etc
I'm asking because although the above example is simple, it would be really helpful to do in a current project I'm working on.
Is it possible to change this parameter, and if not, is there a particular reason as to why not?
Hi,
For Sqilte3 C API, I would use sqlite3_last_insert_rowid. How to get this id when using ActiveRecord after insert a new record? I use following way to insert a new record :
Section.new |s|
s.a = 1
s.b = 2
#I expected the return value of save to be the last_insert_id, but it is NOT
s.save
end
I have a page that has the following div structure:
<div id="name" class="class_name">
How would I style the class?
Like this?
#name .class_name
name .class_name
#name class_name
?
