My send mail task works fine for email ids like [email protected] but it throws error for email ids like [email protected].
is there any way i can make it work for such ids also?
Thanks.
I want to write a function in Java that takes as input an integer and outputs every possible permutation of numbers up to that integer. For example:
f(1)
0
f(2) should output:
00
01
10
11
f(3) should output:
000
001
002
010
011
012
020
021
022
100
....
220
221
222
That is it should output all 27 permutations of the digits of the numbers 0, 1, 2.
f(4) should output
0000 0001 0002 0003 0010 ... 3330 3331 3332 3333
f(4) should output
00000 00001 ... 44443 44444
I have been trying to solve this problem but cannot seem to work out how to do it and keep getting confused by how many loops I need. Does anyone know how to solve this problem? Thanks in advance.

In an Activity, I need to call a web service every 30 seconds or so, and use the data to update the UI.
Is there a recommended approach on how to schedule a repetitive task?

Hi all,
I have developed a mac application, which is continuously interacting with database on linux server. As data is increasing it has become costlier affair in terms of time to fetch data from server. So I am planning to store required data locally, say on mysqlite and find some mechanism through which I can synchronize it with database on linux server.
Can anyone suggest me some way to accomplish it?
Thanks,

Searching online, I see lots of people asking for features to have multiple levels of sub-tasks, and proper sub-task functionality (like FogBugz). But I don't know if it's planned in future versions, or if plugins exist to provide this functionality.
Does anyone know?
Just finished reading ch23 in the excellent 'Beautiful Code' http://oreilly.com/catalog/9780596510046
on Distributed Programming with MapReduce. I understand that MapReduce is a programming system designed for large-scale data processing problems, but I have a hard time getting my head around the basic examples given and how I might apply them in real world situations.
Can someone give a simple example of MapReduce implemented using either java, javascript or actionscript?
Hello i´m trying to set info from a post method into a variable that sets a session named name the value that the user input. I get the following error:

session_start();
$_SESSION['name'] = $session;
Hi All,
I would like to create a set of custom controls that are basically image buttons (it's a little more complex than that, but that's the underlying effect I'm going for) that I've seen a few different examples for. However, I would like to further extend that to also allow radio/toggle buttons.
What I'd like to do is have a common abstract class called ImageButtonBase that has default implementations for ImageSource and Text, etc. That makes a regular ImageButton implementation pretty easy.
The issue I am having is creating the RadioButton flavor of it. As I see it, there are at least three options:
It would be easy to create something that derives from RadioButton, but then I can't use the abstract class I've created.
I could change the abstract class to an interface, but then I lose the abstract
implementations, and will in fact have duplication of code.
I could derive from my abstract class, and re-implement the RadioButton-type
properties and events (IsChecked, GroupName, etc.), but that certainly doesn't seem like a great idea.
Note: I have seen http://stackoverflow.com/questions/2362641/how-to-get-a-group-of-toggle-buttons-to-act-like-radio-buttons-in-wpf, but what I want to do is a little more complex.
I'm just wondering if anybody has an example of an implementation, or something that might be adapted to this kind of scenario. I can see pros and cons of each of the ideas above, but each comes with potential pitfalls.
Thanks,
wTs
I am using XAMPP on windows vista.
In my development, I have http://127.0.0.1/test_website/
Now I would like get this http://127.0.0.1/test_website/ with php.
I tried something like these, but none of them worked.
echo dirname(__FILE__)
or
echo basename(__FILE__);
etc.
I will appreciate any help.
Thanks in advance.
Currently a user makes a purchase and then a license is generated and sent to that user, but the license isn't tied to a physical computer so there is nothing to prevent the user sharing the license with someone.
I heard people talk about creating a license tied to the mac address of the computer, so the license only works on that computer. Now I know how to get the mac address in code but I dont understand how I can do this step when they first make the purchase on the web, so please what is the basic algorithm for node locked licenses ?
I've got a number of tasks/servlets that are hitting the HardDeadlineExceededError which is leaving everything hanging in an 'still executing' state.
The work being done can easily exceed the 29 second threshold.
I try to catch the DeadlineExceededException and base Exception in order to save the exit
state but neither of these exception handlers are being caught...
Is there a way to determine which tasks are in the queue or currently executing?
Are there any other strategies for dealing with this situation?
I often find myself detached from the programming community and I generally find out about all the "cool" things that are happening after they have already happened. So my question is how do you stay connected and up to date with the programming community? Podcasts, blogs, meet ups, conventions, twitter, talking with your co-workers whatever it may be that keeps you connected. Please provide actual examples of which blogs, talks, etc you use.
I would like to use Google Image search, however I can't find the proper url anywhere. Examples always refer to the web search, not the image search. I do not want to use javascript, I need the iamge at server side.
Please, do not simply post links to the API documentation, but preferably the url itself. (Or the missing url argument etc).
http://ajax.googleapis.com/ajax/services/search/web
This is a web search - no changing web to image/img doesn't work.
I'm trying to have a templated class (here C) that inherits from another templated class (here A) and perform static member specialization (of int var here), but I cant get the right syntax to do so (if it's possible
#include <iostream>
template<typename derived>
class A
{
public:
static int var;
};
//This one works fine
class B
:public A<B>
{
public:
B()
{
std::cout << var << std::endl;
}
};
template<>
int A<B>::var = 9;
//This one doesn't works
template<typename type>
class C
:public A<C<type> >
{
public:
C()
{
std::cout << var << std::endl;
}
};
//template<>
template<typename type>
int A<C<type> >::a = 10;
int main()
{
B b;
C<int> c;
return 0;
}
I put an example that works with a non templated class (here B) and i can get the static member specialization of var, but for C that just doesn't work.
Here is what gcc tells me :
test.cpp: In constructor ‘C<type>::C()’:
test.cpp:29:26: error: ‘var’ was not declared in this scope
test.cpp: At global scope:
test.cpp:34:18: error: template definition of non-template ‘int A<C<type> >::a’
I'm using gcc version 4.6.3, thanks for any help
Hi all,
my first question on stackoverflow!!
I'm usgin the last NANT version: 0.90
How do i specify the lib names using the task?
Example: how do i link with the gtest.lib?
Morover i have a curisoity: why NANT doesn't allow an external property file?
Example:
It would be great if one of the developer answers.
Is there a ratio or is only not enough developing time?
I will be teaching an econometrics course to masters students in the fall. I think it is important for them to learn programming with data as an essential applied research skill. What suggestions do you have for the programming language. I am leaning mostly towards R. What others should I consider?
I have a class with protected constructor:
class B {
protected:
B(){};
};
Now I derive from it and define two static functions and I manage to actually create objects of the class B, but not on the heap:
class A : public B {
public:
static B createOnStack() {return B();}
//static B* createOnHeap() {return new B;} //Compile time Error on VS2010
};
B b = A::createOnStack(); //This works on VS2010!
The question is: 1) Is VS2010 wrong in allowing the first case? 2) Is it possible to create objects of B without modifying B in any way (no friendship and no extra functions).
I am asking, because it is possible to make something similar when dealing with instances of B and its member functions, see:
http://accu.org/index.php/journals/296
Thank you in advance for any suggestion!
Kind regards
I have a class B which inherits from A which in turn derives from enabled_shared_from_this. Now, I want to get a shared pointer to B from an instance of B. shared_from_this will return shared_ptr<A>, not shared_ptr<B>. Should I use boost::static_pointer_cast here? Or is there a better way?
Hello,
I am currently using the delayed_job gem and I was wondering how to run a rake task every 5 minutes.
I want to run "rake ts:reindex RAILS_ENV=production" every 5 minutes but I'm not sure where to start. I really don't have much more I can say about this because I am VERY inexperienced in this area of rails development.
i m developing a application for administrative purpose, it's developed completly but now i m stuck with hiding process from taskmanager, because my application monitor the users activity and send reports to admin, i have hide the application but i m not able to hide the process from task manager.
my basic database setup is:
User:...
Info:
relations:
User: { foreignType:one }
When displaying information on the user it takes: 1 query to find info on the user, and 1 query to find additional info
I want to reduce this to one query that finds both, I assume I need to override a function from BaseUser.class.php, or something along those lines but I'm not really sure what to do.
Thanks!
Hi,
Is it possible for kids with only HTML/CSS programming experience to do game programming in SilverLight 4.0?
They are using Visual Web Developer 2010 Express edition.
Do they have to learn c# or any other language since they are just starting out?
Thanks
I'm 16. I started programming about a year ago when I was about to start high-school. I'm going for a career in programming, and I'm doing my best to learn as much as I can. When I first started, I learned the basics of C++ from a book and I started to learn things by myself from there on. Nowadays I'm much more experienced than I was a year ago. I knew I had to study by myself because high-school won't (likely) teach me anything valuable about programming, and I want to be prepared.
The question here is: how important is it to study programming by oneself?
