Currently I am doing the profiling to a piece of code. During the profiling, I discovered that this very method call,
Class<T>.isAssignableFrom(Class<?> cls)
takes up to quite amount of the entire time.
Because this is a method from reflection, it takes a lot of time compared to normal keywords or method calls. I am wondering if there are some good alternatives for this method calls?
I have a $.ajax call with an error callback:
error: function(result){
$('#msg').text(result.statusText).addClass('err');
}
I'd like to change it to a more generic:
error: myError(result)
And then all by itself:
function myError(theError){
$('#msg').text(theError.statusText).addClass('err');
}
But firebug is telling me "result" is not defined.
var r = /\d/g;
var a = r.test("1"); // will be true
var b = r.test("1"); // will be false
console.log(a == b); // will be false
Please explain to me why the result of r.test("1") alternates with each call?
I was able to work around the issue I was having by removing the g modifier. However I would still like to understand why this happens.
take this simple code:
class A{
public:
virtual void foo() = 0;
void x(){ foo(); }
};
class B: public A{ foo(){ ... } };
main(){
B b;
b.x();
}
What I want is to build an abstract class that will have a function that will call a function expecting it to be implemented in the derived class
Thanks,

I let my users create photo albums with many photos. Relationship as follows:
has_many :album_photos, :dependent => :destroy
i upload photos to S3
When the user delete album I want to delete all photos as the relationship shows but it takes time if the user has many photos.
Can I automatically set photo deletion to happen in the background (delayed_job) without having to manually call 'send_later' on every photo?
In what cases would a call to java.sql.ResultSetMetaData.isSearchable(int col) return false for an Oracle database? The documentation for the method doesn't really answer the question:
"Indicates whether the designated column can be used in a where clause."
I can think of only one case - when the column is the result of an aggregate function (in which case it would have to be part of a HAVING filter, not a WHERE filter).
Are there any other cases?
With jQuery I'm retrieving positions of a sortable list using 'serialize', like this:
var order = $('ul').sortable('serialize');
The variable 'order' then receives the following:
id[]=2&id[]=3&id[]=1&id[]=4&id[]=5
Now how can I use this data in an ajax call?
This is how I plan to do it, but it's ugly and I can't change the parameter name 'id':
$.post('ajax.php?'+order,{action:'updateOrder'});
Maybe I need to unserialize, then implode the variable 'order' and assign it to just one parameter?
What would you call the effect applied to the backgrounds in the Giygas fight of Earthbound, and the battle backgrounds in Mother 3? This is what I'm talking about.

Now anyone know how I could go about this without using animated images, or using openGL?
I have multiple layers in an application and i find myself having to bubble up events to the GUI layer for doing status bar changes, etc . . I find myself having to write repeated coded where each layer simply subscribes to events from the lower layer and then in the call back simply raise an event up the chain. Is there a more efficient way of doing this?
I have created CMyClass,in which defined one method CallMe().when I build this project MyProject.dll is generated.
Now in some another project, I want to call CallMe of CMyClass .
can anybody tell me how to do it ?
Thanks in advance....
How does you call this statement?: $arr = array();
initialize an array
or
declare an array?
In brief, how would you comment such a statement? (P.S. That array would then hold a bunch of values.)
EDIT: I doubt because what I basically do is declare a variable of a particular type, don't I?
module MyModule
def my_method; 'hello'; end
end
class MyClass
class << self
include MyModule
end
end
MyClass.my_method # => "hello
I'm unsure why "include MyModule" needs to be in the eigenclass in order to be called using just MyClass.
Why can't I go:
X = MyClass.new
X.my_method
How is this type of pattern useful if I can't call it from an instance?
I seem to recall that Loader.unload() could once be used to stop loading a swf before it had finished loading. I can no longer find documentation or the blog where I read this. Perhaps it was an unofficial feature. Anyhow, IModuleInfo, returned by ModuleManager.getModule() has an unload() method. If I want to halt loading a Flex Module that is in progress, do I just call iModuleInfo_instance.unload()?
Hello,
I have a huge controller in codeigniter, with many functions. I want to limit access to certain functions. How should I proceed?
And can I call the functions using cron daemon???
Does anybody know if it's possible to call a webservice with an attachment from Flex Webservices?
I was looking around, and it seems that you can do that in Flash Player 10... any clue? Any documentation?
Thanks in advance!
Hi,
In my C++ program, I need to call this c API:
GConn* gnet_conn_new (const gchar *hostname,
gint port,
GConnFunc func);
where GConnFunc is defined as:
void (*GConnFunc) (GConn *conn);
My question is if I have a C++ class and have a member function like
Class A {
public:
A();
void my_func (GConn* conn);
}
In my A::A() Constructor, how can I pass this-myfunc to gnet_conn_new as the GConnFunc parameter?
Thank you.
Hi everybody.
I made a custom helper extending the system string_helper.php.
I placed it in my /application/helpers folder, called MY_string_helper.php as required, unit-tested its functions.
Now, when I try to call one of its functions from a model, it does not work.
The functions in the default string helper work, instead. It looks like my extension is not loaded for some reasons.
Thanks a lot, and happy holidays.
Hi.
I have a small isuse regarding an interface.
Consider this code:
[HttpPost()]
public void Update(IAuctionItem item) {
RedirectToAction("List");
}
Whenever I call this I get an exception saying I can't create an instance of type which i totally correct. But is there a way of telling what the interface should map to without actually using the concrete type ?

I have a SSIS package that I plan to deploy on my SQL Server 2008 machine.
I need to call this SSIS package remotely and synchronously from .NET. Obviously I need to pass parameters to this package as well.
How could I do that?

I want to search for files on the users mobile with specific extensions.
I tried searching but could not find any direct API's.
Is there a specific API's or is there tedious way of achieving the same.
Or is there a mechanism to call linux calls for find or something similar
Thanks
