I have webpage I downloaded with C++ to a string, and it is basically a massive list of links. I need to find the last 2 elements of the list. Can anyone help me on how to do this?
In Java you can build up an ArrayList with items and then call:
Collections.sort(list, comparator);
Is there anyway to pass in the Comparator at the time of List creation like you can do with TreeMap? The goal is to be able add an element to the list and instead of having it automatically appended to the end of the list, the list would keep…
I have an activity that I want to programmatically stop after some elapsed time. I have a GL view running.
My understanding is that the GLSurfaceView.renderer is running in its own thread, so I created a handler instantiated from the activity. In the GLSurfaceView I post a message. The handler then attempts to stop the activity with the…
I am developing an image cropper and would like to ask you the following question: In order to prevent the default drag n' drop action when you press the left button on an image and keeping it pressed try to move the mouse, wouldn't it be cross-browser if to just use the picture as a background to a div box?
Just like so:

I'm looking for a way to listen for an event in the HTML/CSS of a webpage. Basically, a website I use at work lists queues and appointments, which flag as yellow/red based on the amount of time late on taking said appointment. Other than this visual aide, there is no alert of any kind, which is a failing point if one is juggling…
I have been searching around, but there seems no good answer for this simple question. So I am asking again: how to animate line-drawing in iphone dev?
Basically what I want is something like this:
@implementation MyUIView
- (void) triggerLineDrawing: (CGPathRef) path {
...
// animate line drawing here
}
Can it be…
I am having trouble compiling and running the ActionBarCompat sample of Android 16. I have API level 16 as the build target selected, which seems to build fine, but when I try to debug these errors pop up. Of course I could change the min API level in the manifest, but what would be the point of that? I have made no changes…
I have a Django application with users. I have a model called "Course" with a foreign key called "teacher" to the default User model that Django provides:
class Course(models.Model):
...
teacher = models.ForeignKey(User, related_name='courses_taught')
When I create a model form to edit information for individual…
I'm building a mobile AIR app using Flash Builder 4.5. The initial view in my views package is TestHomeView.mxml. I want to refer to it in one of my .as classes elsewhere in the app, and I'm not sure how to do that.
Theoretically I should be able to add an "id" attribute to TestHomeView.mxml, but FB gives me an error: "id…
SELECT u.id, u.honour, COUNT(*) + 1 AS rank
FROM user_info u
INNER JOIN user_info u2
ON u.honour < u2.honour
WHERE u.id = '$id'
AND u2.status = 'Alive'
AND u2.rank != '14'
This query is currently utterly raping my server. It works out based on your honour what rank you are within the 'user_info' table which…
I hear all this stuff about crazy ways to build iPhone apps using Ruby or C# under .NET or the like. Even stuff about developing apps on Windows using Java, or auto-generated apps using Flash CS5 or something.
Now, I've never really spent any time at all investigating these claims—I just brushed them off as clumsy or…

Is it possible to create an instance of a generic type in Java? I'm thinking based on what I've seen that the answer is "no" (due to type erasure), but I'd be interested if anyone can see something I'm missing:
class SomeContainer<E>
{
E createContents()
{
return what???
}
}
EDIT: It…

When using Excel (2003) to provide data for my unit tests it seems to think that when a cell has TRUE / FALSE value that it is null when there has been no preceding cell values e.g.
if (TestContext.DataRow["SatisfactionExtremelySatisfied"] != DBNull.Value)
model.SatisfactionExtremelySatisfied =…
It seems that the software language skills most sought for embedded devices and robots are C, C++, and LISP. Why haven't more recent languages made inroads into these applications?
For example, Erlang would seem particularly well-suited to robotic applications, since it makes concurrent programming…
A client recently requested some fancy processing based off of the Gateway attribute registered with a Paid order. When I receive, validate and inspect the JSON of the order, I am logging the gateway attribute and finding it is nil at times.
When I check the order using the API after the Webhook,…

Hi, I am working on a C++ application that uses computer vision techniques to identify various types of objects in a sequence of images. The (1000+) images have been hand-classified, so we have an XML file for each image containing a description of where the objects are actually located in the…
Hello,
I am creating an Excel file on a web server, using OleDb to connect the the physical (well as physical as it can be) file and appending records. I am then returning a FilePathResult to the user via MVC, and would like to delete the physical file afterwards due to data protection…
I have a company that would like to bring me in to serve me an hour long exam. No resources other than a pencil and paper. I really couldn't get any sort of feedback on the type of exam (implementation or generic) beside that it would test a few specific areas.
Have you done anything…
This is undoubtedly a simple question. I used to do this before, but it's been around 10 years since I worked in C++ so I can't remember properly and I can't get a simple constructor call working.
The idea is that instead of parsing the args in main, main would create an object…
I expected these generators to be available:
