http://stackoverflow.com/questions/11416191/how-to-convert-matchcollection-to-string-array/11416739#comment15078364_11416739
Given The two Linq expressions:
var arr = Regex.Matches(strText, @"\b[A-Za-z-']+\b")
.OfType<Match>() //OfType
.Select(m => m.Groups[0].Value)
.ToArray();
and
var arr = Regex.Matches(strText, @"\b[A-Za-z-']+\b")
.Cast<Match>() //Cast
.Select(m => m.Groups[0].Value)
.ToArray();
OfType<> was benchmarked by user [Alex][1] to be slightly faster (and confirmed by myself).
This seems counterintuitive to me, as I'd have thought OfType<> would have to do both an 'is' comparison, *and* a cast (T).
Any enlightenment would be appreciated as to why this is the case :)

I have built this function that gets the subscriptions (max 50) and calls it self to get more if the user has over 50 subscriptions.
But I can't figure out how to merge the arrays from each function call. (see the while loop in the end).
As it works now the new arrays will just overwrite the old ones but I have tried adding the arrays to a main array and returning it but that will just place the arrays in them self.
The foreach loop returns an array that looks like this:
Array
(
[0] => Array
(
[channelName] => break
[channelLink] => https://www.youtube.com/channel/UClmmbesFjIzJAp8NQCtt8dQ
)
[1] => Array

[channelName] => kn0thing
[channelLink] => https://www.youtube.com/channel/UClmmbesFjIzJAp8NQCtt8dQ
)
[2] => Array
(
[channelName] => EpicMealTime
[channelLink] => https://www.youtube.com/channel/UClmmbesFjIzJAp8NQCtt8dQ
)
)
So the problem is the while loop. Got any ideas?
// Get an array with videos from a certain user
function getUserSubscriptions($username = false, $startIndex = 1, $maxResults = 50) {
// if username is not set
if(!$username) return false;
// get users 50 first subscriptions
// Use start-index to get the rest

curl_close($ch);
// convert xml to array
$subscriptionsArray = XMLtoArray($subscriptionsXML);
// Ge total number of subscriptions

// Parse array and clean it up

}
// if we did not get all subscriptions, call the function again
// but this time increase the startIndex

$startIndex = $startIndex+$maxResults;
$subscription = getUserSubscriptions($username, $startIndex);
}
return $subscription;

class Abstract {
public:
// ...
virtual bool operator==(const Abstract& rhs) const = 0;
// ...
};
Now suppose I'm creating multiple derived classes from this abstract class. However, each one uses a different algorithm when comparing with its own type, and a generic algorithm when comparing with any of the other derived classes. Between the following two options, which would be the better, more efficient option?
Option A:
class Derived : public Abstract {
public:
// ...
bool operator==(const Abstract& rhs) const {
// Code for comparing to any of the other derived classes
}
bool operator==(const Derived& rhs) const {
// Code for comparing to myself
}

};
Option B:
class Derived : public Abstract {
public:
// ...
bool operator==(const Abstract& rhs) const {
const Derived* tmp = dynamic_cast<const Derived*>(&rhs);
if (tmp) {
// Code for comparing to myself
}
else {
// Code for comparing to any of the other derived class
}
}
I'm really curious as to what advantages and disadvantages these options would have, as C++ typecasting is a relatively mysterious topic to me. Furthermore, which solution is more "standard", and does the second solution have any impacts on performance?
Is there possibly a third solution? Especially if there were many derived classes, each needing its own special comparison algorithm against different derived classes? | c++ | inheritance | casting | overloading | dynamic-cast | null | open | Dynamic Casts or Function Overloads?

I am collecting some requirements for a web site that i am designing.
The issue I am having is to decide which scenario would be more [economic, buggy, functional].
It is a real estate web site, that has ability "by admin" to dynamically build characteristics (both functionally and GUI) for real estate types (Villas, Buildings , ...).
Lets talk about Integer case, as it is the most straight forward one,
a- number of bedrooms in apartments , expected values (1-7).
b- number of levels in skyscrapers , expected values (20-200).
c- area in meter squares in lands , expected values (100-5000).
Web site Admin should be able to generate all the three cases (a,b,c) , so that the user can fill data as:
1- radio button
2- drop down menu
3- text field
I have two scenarios to design that "please tell me if you have a third one" :
**Scenario 1:**
tie number of options to GUI. i.e.
- Radio buttons (#expected values < 8 ) , e.g. "a"
- Drop down ( 8 =< #expected values < 200)
- Text Field ( 200 =< #expected values )
**Scenario 2:**
Simply, let Admin decides what GUI (1, 2, or 3) is corresponding to what case (a, b, or c).
Which scenario is cheaper? less buggy ? more functional "from business point of view" ?
Sorry for rambling !!! It is a design issue

EntityBean.getDAO() has non-API return type GenericDAO<T, ID>
A Google search for "has non-API return type" only shows instances where this message appears in problem lists. I.e., there's no public explanation for it.
What does this mean? We can create a usage problem filter in Eclipse to make the message go away, but we don't want to do this if our usage is a legitimate problem.

So here we go.
What I want to do is have a a 3d office, with a desk.
I would be using sticky notes to write notes and stick them to wall or desk.
It will only have two options to send it to your email address or change the font.
This is basically writing notes on a sticky note, the only diffference is that the background, which is a 3d office.
And also sticking it on the wall or desk.
By a 3D view as Ted has mentioned i mean the perspective view.

I have a class which contains data for each frame received, and I would like to implement a dispose method to run once the frame data has been processed. The problem is the primary object I wish to dispose of (an image buffer) is only accessible via a pointer.
I don't know if this is even necessary in C#. I know that in C++ I would have to do something with it to prevent a memory leak, however I don't know much about how pointers work in C# in terms of garbage collection. As it is, the program works okay, but the memory usage does jump around a lot more than I'd like it to. I've found that proper disposal of certain objects has given much more consistent memory usage compared to relying on what I assume to be finalizers being automatically run, such as when disposing of an existing image on an image box before setting a new one. I'd like to try something similar here if possible.
Potentially important: the data the pointer points to is processed by unsafe code, which creates two new pointers to the object (one as UInt16* and another as byte*). Both of these pointers only exist within the scope of the unsafe routine but I'm not sure if this interferes with GC in some way.
Any advice, recommendations appreciated. Thanks | c# | pointers | garbage-collection | null | null | null | open | Dispose of an object referenced via pointer in C#

I’ve finally created some cases and plans on where I want to go with this project. I will have to create both a web application (ASP.NET) and a desktop application (Java). Both these applications will need to have sync’d databases.
I’ve been thinking about creating a public API over my database so my front-end and 3rd parties could communicate to the database. But I’ve never really attempted something like this before. I’ve spend my weekend so far on reading up on how I could approach this and I’ve gotten a pretty good idea. I’m having some questions/doubts currently and was hoping perhaps someone could help me.
1) I’m currently still in university and I don’t have a job so my pockets don’t go very deep. I’ve been thinking of writing the API in PHP, I already have possession of an unmetered hosting account and else I would be forced to buy .NET hosting which can turn out to be quite expensive. However my PHP knowledge is quite limited towards parsing user input/security. Would it be wise to search for an (e)book around this topic or would I be fine with online tutorials, do you have any suggestions on where to look? Should I put my time in writing a possible vulnerable PHP API or should I look at other options?
2) So far I’ve never really had the need to look into PHP libraries. I was wondering if I should look into some of these (for example cakePHP) to help me develop the API.
3) I’ve experience with implementing Twitter/Linkedin their API’s so I’ve been thinking to use OAuth (v2) to allow people to use my API. Is implementing OAuth to your API a lot of work? Is it well documented enough for someone with only basic PHP knowledge? If you ever used it on your API, what was your experience with it?
4) If this project would ever kick off, it would be wise to look into hosting It in the cloud. Do I currently need to think about something so future cloud integration is possible?
5) For the web application, would there be a (big) performance difference between using the API or directly connecting to the database?
6) Any recommended lecture or tips are welcome. It’s the first time I will be attempting something this big (both in functionalities & required knowledge).

(Management know nothing about development and only see the problem in transferring projects from one developer to another. Customers pay by the hour and development is a small part of total project so code quality is a non-issue)
My first step is to set up guidelines for C# and VB.Net (SQL will probably come later).
(Most code here is created with <kbd>CTRL-C</kbd><kbd>CTRL-V</kbd> and testing is done with <kbd>F5</kbd>.
I have tried to introduce unit testing / code review but that is not going to happen. Static analysis is the only way forward at the moment)
I am most comfortable in C#/C++ (but sometimes work with existing VB6/VBA/VB.Net code) so setting up C# guidelines is pretty easy:
* Warning Level 4
* StyleCop
* FxCop
* Code metrics (e.g. Cyclomatic complexity < 15, Maintainability > 50)
For VB.Net I need to replace StyleCop with some written guidelines but how do I set up the VB.Net compiler.
Personally I never code without `Option Explicit` / `Option Strict` etc but if I do that on our VB.Net projects I get hundreds of warnings/errors (implicit conversions, default return type/value etc).
The VB developers does not seem to have a problem working without help from compiler warnings. I do not think their productivity generally differs from C# developers (it is more a personal thing).
I do not want to enforce my own preference for static checking so my questions is:
**What warning levels are reasonable/best practice for VB.Net development?**
(English is not my first language so I hope this does not sound like I think VB.Net or VB Developers are inferior to C# in any way. I just don't have much experience in VB.Net projects)

The site will behave differently based on which domain name the request is coming from. Nothing fancy, just loading different layouts with a few other simple bits and bobs.
Currently, the web.config contains the valid domains the code acts upon and everything seems to be working fine so far.
Whenever I hit Run in Visual Studio, it fires up the developer server instances with the usual _localhos:xxxx_ address.
If I want to test each layout in VS, I need to configure _localhost_ to be associated with the layout I wish to load.
I could manage to live with how it is right now, but everything is on TFS, so if someone checks out the file (for testing) and forgets to check back in, it can cause some headaches.
So I was wondering if anyone had some decoupled way to fire up a site with a specific address while maintaining the ability to easily debug (preferably not by deploying to IIS)

I have a results table which has GoldID, SilverID, and BronzeID. I have done it this way because the ID may be for an individual or a team (DivisionGroup = "Team" or something else). The results could also be for type A or type B (DivisionType = "A" or "B").
public int GoldID { get; set; }
public int SilverID { get; set; }
public int BronzeID { get; set; }
public string DivisionGroup { get; set; }
public string DivisionType { get; set; }
I'm pretty sure the following will get me results for individuals but I'd rather do it in one query if there is a way.
var GoldIndividual = from r in context.Result
where r.DivisionGroup != "Team" &&
r.TournamentsID == TournamentID &&
r.GoldID == ParticipantsID
select r;
var SilverIndividual = from r in context.Result
where r.DivisionGroup != "Team" &&
r.TournamentsID == TournamentID &&
r.SilverID == ParticipantsID
select r;
var BronzeIndividual = from r in context.DivisionGradeResult
where r.DivisionGroup != "Team" &&
r.TournamentsID == TournamentID &&
r.BronzeID == .ParticipantsID
select r;
The teams thing is messing me up completely. The GoldID, SilverID, and BronzeID is the ID of the Teams table. The teams table has a collection of participants. Joining the participants table has nothing to join on because the team.participants is a collection.
The following SQL works (this is in SQL Compact 4.0) but I don't know how to make it into LINQ because "TeamsA_TeamsAID" doesn't exist in the entity object. Participants do but as a collection I can't go "Participants.ParticipantsID"
SELECT COUNT(GoldID)
FROM Results
INNER JOIN TeamsA ON Results.GoldID = TeamsAID
INNER JOIN Participants ON TeamsA_TeamsAID = TeamsAID
WHERE ParticipantsID = 1
AND DivisionGroup = 'Team'
AND DivisionType = 'A'
This one will also need to do it for gold, silver, and bronze. Again, in one query would be nice. Especially considering I have to do it all again against TeamsB on DivisionType "B".

Using a list of 15 numbers, I need to give a list representing the best and worst case scenario. It says "q.s. uses the first item in the list as the pivot item". I'm not sure if I pick the first item as pivot everytime, but that's what I'm assuming....

This way the UserControl will be binded to the ViewModel from stock.
Looks as a good idea to me but I never saw such a thing.

Why do we have to use this:
makeText(Context context, CharSequence text, int duration)
instead of this:
new Toast(Context context, CharSequence text, int duration)
This is the makeText method:
public static Toast makeText(Context context, CharSequence text, int duration) {
Toast result = new Toast(context);
LayoutInflater inflate = (LayoutInflater)
context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = inflate.inflate(com.android.internal.R.layout.transient_notification, null);
TextView tv = (TextView)v.findViewById(com.android.internal.R.id.message);
tv.setText(text);
result.mNextView = v;
result.mDuration = duration;
return result;
}
Why don't we have the following:
public Toast (Context context, CharSequence text, int duration) {
this(context);
LayoutInflater inflate = (LayoutInflater)
context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = inflate.inflate(com.android.internal.R.layout.transient_notification, null);
TextView tv = (TextView)v.findViewById(com.android.internal.R.id.message);
tv.setText(text);
this.mNextView = v;
this.mDuration = duration;
}
I searched the web and source code for any reason but I didn't find.

Now I have a data set which stands for acquaintance network in social network. I want to visualize this network. In this network, vertex stands for user and edge stands for acquaintance relationship. Now I use igraph package for R to achieve my goal. However, my data set is too large with more than 100,000 vertexes and more than 1000,000 edges, which causes the generated graph not clear. In fact, the graph is totally unrecognized. How can I get a clear graph using igraph package? Or, which software can complete this task?

Basically we have a part of our website that runs Speedtest to determine somebody's bandwidth and use its results in some if statements. But when the person tries to change panels and come back in, Speedtest just sort of disappears. It's supposed to go back to the beginning and start again, but it's like it just keeps running and turns invisible.
When I tried loading another .swf in the SWFLoader, I could get it to reset just fine without disappearing. There's something specifically about Ookla's Speedtest that's causing a problem. If I do nothing to reset the Speedtest .swf when the user starts moving around panels, it won't disappear at least. Putting in code to make it reset is a completely different story though.
What's the trick for this program? Did Ookla design the .swf specifically so it wouldn't work like that or something?

How do I get the data from get_data into both widget_class and page_class? I could just insert something like `$data = new get_data();` in each class, but that's not the most efficient way of doing things since it would pull the external data twice, right?
My knowledge of OOP is limited, so any help would be great.
