  • Searching in a TreeMap (Java)

    - by Kronen
    I need to do a search in a map of maps and return the keys this element belong. I think this implementation is very slow, can you help me to optimize it?. I need to use TreeSet and I can't use contains because they use compareTo, and equals/compareTo pair are implemented in an incompatible way and I can't change that. (sorry my bad english) Map m = new TreeSet(); public String getKeys(Element element) { for(Entry e : m.entrySet()) { mapSubKey = e.getValue(); for(Entry e2 : mapSubKey.entrySet()) { setElements = e2.getValue(); for(Element elem : setElements) if(elem.equals(element)) return "Key: " + e.getKey() + " SubKey: " + e2.getKey(); } } }

    - by vettipayyan

I proceeded as specified in this question : I referred this i have provided wat i've coded ."command" and "option" are QComboBoxes ( Pardon me for bad style) Is there any mistake in Indexes ? self.command.insertItem(1,'Convert') self.command.insertItem(2,'Compose') self.command.insertItem(3,'Animate') self.option.insertItems(268,list) and retrieval : self.selected_com=self.command.itemData(self.command.currentIndex()) self.selected_opt=self.option.itemData(self.option.currentIndex())

  • c++ - FIFO implementation

    - by Narek
    While implementing a FIFO I have used the following structure: struct Node { T info_; Node* link_; Node(T info, Node* link=0): info_(info), link_(link) {} }; I think this a well known trick for lots of STL containers (for example for List). Is this a good practice? What it means for compiler when you say that Node has a member with a type of it's pointer? Is this a kind of infinite loop? And finally, if this is a bad practice, how I could implement a better FIFO.

  • If you could remove one feature of php ti help newbies what would it be?

    - by Chris
    If you could remove one feature from PHP so as to discourage, prevent or otherwise help stop newer programmers develop bad habits or practices, or, to stop them falling into traps that might hinder their development skills what would it be and why? Now, before the votes to close it's not as open-ended as you might think. I'm not asking purely what is the worst feature or what feature would you really like to remove purely arbitrarily. Yes, there may not be one correct answer but I suspect there will be many similar answers which will provide me with a good idea of things I might be doing wrong, even inadvertently.

  • MVC2 JSON action, if I want to be RESTful should I allow GET, POST, or Both?

    - by Yads
    The project I'm currently working has a whole bunch of JSON actions in order to populate cascading dropdowns via ajax calls. Since they're technically Select queries and we're trying to be RESTful, we've been marking these actions with the HttpGet attributes. However by default, JsonResultdoes not allow to return results via a GET. So we've had to explicitly call Json(data, JsonRequestBehavior.AllowGet). What I'm wondering is, is this bad practice? Should we only be allowing Post requests to our Json actions? If it makes a difference, this is an enterprise application, that requires a log in to a particular environment before it can be accessed.

  • Snapping elements / conditional layouts

    - by Felix
    Sorry for the extremely bad title, I have no other idea what to call this question. What I'm trying to do is this: have a RelativeLayout which has two children: one with layout_centerInParent="true" one with layout_alignParentBottom="true" However, when the device is in landscape mode, element (1) appears slightly over or under element (2). But, element (1) has enough space above it to appear above element (2). How could I make the layout so that if the screen is too small to center element (1) and make both elements not overlap, then align element (1) above (as in layout_above) element (2)?

  • Clone a 'link' in SWT

    - by Steve
    I have a table of information that includes a username, an ip address, and a timestamp. What I wanted to do was to have the ip address contained within a link object that when the link is clicked it utilizes bgp.he.net to get information about the host/IP address. I have tried creating threads to resolve the IP addresses but it is often a large amount of IP addresses and I read that InetAddress#getByName isn't non-blocking, so I figured having links that go to this site is the next best thing. Question is: Is it possible to have links for each of my IP addresses in the table without creating a new link object for each row? I don't know how bad that would be on memory usage which is why I'm inquiring about cloning an instance of an IP and having the link open bgp.he.net/link.getText()

  • This is right way for database?

    - by ciss
    Hello, i have some issue with database. Okay, i have two models - Page and Item. Page for displaying some content. Item - this is item discription. So, i work on small ecommerce shop. Okay, all of this models can have some comments. So, this is my Comments model at this moment: Comments - string : id text : body integer : page_id integer : item_id So when some one add comment to page - page_id will be filled with current Page id. And if some one add comment to item - item_id will be filled. Okay, i know what the best way is to create STI or Polymorphic assoc, but does i really need this way for my situation? Sorry for my bad english, i'm from Russia.=)

  • Identifying when there is more than 1 in a group based on grouped field

    - by Brian Cascone
    Sorry for the bad description it is tough to explain in one sentence. I have a dataset that has Cause field (RootCause) and an ID field (GroupID). Both can be many things but I need to identify where a GroupID has a multiple different rootcauses. for example: RootCause GrpId AAA 111 BBB 222 CCC 111 I am looking to be able to identify that GrpId 111 has two different RootCauses. This is what I have so far: Select [RootCause], GrpId, Count(GrpID) as CntGrpId From DB.dbo.Table Where DatatypeField <> '' Group BY [RootCause],GrpId This results set visualy gives me enough information to identify what I am looking for, but i need something better. I am looking to return only the ones that have multiples. Any ideas? Thanks

  • When using out parameters in a function, is it good practice to initialize them in the function?

    - by adambox
    I have a function that uses out parameters to return multiple values to the caller. I would like to initialize them in the function, but I wasn't sure if that's a bad idea since you don't know when you call the function that it's going to change the values right away. The caller might assume that after the function returns, if whatever it was doing didn't work, the values would be whatever they were initialized to in the caller. Is it ok / good for me to initialize in the function? Example: public static void SomeFunction(int ixID, out string sSomething) { sSomething = ""; sSomething = something(ixID); if (sSomething = "") { somethingelse(); sSomething = "bar" } }

  • Yet another URL prefix regex question (to be used in C#).

    - by Hamish Grubijan
    Hi, I have seen many regular expressions for Url validation. In my case I want the Url to be simpler, so the regex should be tighter: Valid Url prefixes look like: http[s]://[www.]addressOrIp[.something]/PageName.aspx[?] This describe a prefix. I will be appending ?x=a&y=b&z=c later. I just want to check if the web page is live before accessing it, but even before that I want to make sure that it is properly configured. I want to treat bad url and host is down conditions differently, although when in doubt, I'd rather give a host is down message, because that is an ultimate test anyway. Hopefully that makes sense. I guess what I am trying to say - the regex does not need be too aggressive, I just want it to cover say 95% of the cases. This is C# - centric, so Perl regex extensions are not helpful to me; let's stick to the lowest common denominator. Thanks!

  • crash happens when NSMutableArray is returned?

    Hi, I have coded like that(that function will be called again and again), but the returned object gives "BAD ACCESS", the NSLog prints correct string, but toReturn sometimes(i called again and again) gives crashes..any help to alter this code - (NSMutableArray *)getAll:(NSString *)type { NSLog(@"Type: %@", type); NSMutableArray *toReturn = [[NSMutableArray alloc] initWithCapacity:0] ; rs = [db executeQuery:Query1]; while ([rs next]) { [toReturn addObject:[rs stringForColumn:@"Name"]]; NSLog(@"name: %@", [rs stringForColumn:@"Name"]); } [rs close]; return toReturn; }

  • What is the difference between these two ways of creating NSStrings?

    - by adame
    NSString *myString = @"Hello"; NSString *myString = [NSString stringWithString:@"Hello"]; I understand that using method (1) creates a pointer to a string literal that is defined as static memory (and cannot be deallocated) and that using (2) creates an NSString object that will be autoreleased. Is using method (1) bad? What are the major differences? Is there any instances where you would want to use (1)? Is there a performance difference? P.S. I have searched extensively on Stack Overflow and while there are questions on the same topic, none of them have answers to the questions I have posted above.

  • Run a proc on several different values of one parameter

    - by WEFX
    I have the following query that gets run within a proc. The function MyFunction returns a table, and this query joins on that table. This proc works great when a @MyArg value is supplied. However, I’m wondering if there’s a way to run this on all @MyArg values in the database. I’m sure there’s a way to do it within a loop, but I know that loops are generally to be avoided at the db layer. I really just need to perform this for the sake of checking (and possibly cleansing) some bad data. SELECT ColumnA, ColumnB, ColumnC FROM ( SELECT a.ColumnA, a.ColumnB, a.ColumnC, ROW_NUMBER() over(partition by a.ColumnD order by f.ColumnX) as RowNum FROM dbo.MyTableA AS a INNER JOIN dbo.MyFunction(@MyArg) f ON f.myID = a.myID WHERE (a.myBit = 1 OR a.myID = @MyArg) ) AS x WHERE x.rownum = 1;

  • Python Continue Loop

    - by Rob B.
    I am using the following code from this tutorial (http://jeriwieringa.com/blog/2012/11/04/beautiful-soup-tutorial-part-1/). from bs4 import BeautifulSoup soup = BeautifulSoup (open("43rd-congress.html")) final_link = soup.p.a final_link.decompose() trs = soup.find_all('tr') for tr in trs: for link in tr.find_all('a'): fulllink = link.get ('href') print fulllink #print in terminal to verify results tds = tr.find_all("td") try: #we are using "try" because the table is not well formatted. This allows the program to continue after encountering an error. names = str(tds[0].get_text()) # This structure isolate the item by its column in the table and converts it into a string. years = str(tds[1].get_text()) positions = str(tds[2].get_text()) parties = str(tds[3].get_text()) states = str(tds[4].get_text()) congress = tds[5].get_text() except: print "bad tr string" continue #This tells the computer to move on to the next item after it encounters an error print names, years, positions, parties, states, congress However, I get an error saying that 'continue' is not properly in the loop on line 27. I am using notepad++ and windows powershell. How do I make this code work?

  • Rotating Viewbox contents smoothly

    - by user204562
    I'm looking to teach myself better methods of doing things in WPF that I would normally do manually. In this case, I have a ViewBox with an image in it. I also have a button that uses a DoubleAnimation to rotate the image 90 to the right. This animation works fine, but obviously because it's square as it turns, the image does a "best fit" to the ViewBox which makes the rotation look quite bad, as it gets larger and smaller as its longest edge shrinks or grows to fit to that particular rotation angle. I am looking for any advice on the best way to handle this using appropriate WPF methods. Obviously I could do all the calculations manually, but I would be more interested in finding a way to use the controls and methods built into the .NET architecture. Thanks for your help.

  • How to view the GDTR's value ?

    - by Mehdi Asgari
    Hi In the book "Rootkit Arsenal" page 84 (Chapter 3) mentions: ..., we can view the contents of the target machine's descriptor registers using the command with the 0x100 mask: kd rM 0x100 and a paragraph below: Note that the same task can be accomplished by specifying the GDTR components explicitly: kd r gdtr .... I run Windbg on my Win XP (inside VMWare) and choose the Kernel Debug - Local. My problem is in case of first command, windbg errors with: lkd rM 0x100 ^ Operation not supported in current debug session 'rM 0x100' and in the second command: lkd r gdtr ^ Bad register error in 'r gdtr' Can anyone guide me ?

  • How can I implement log4j logging to an existing J2EE Struts web application?

    - by Ruepen
    I have recently inherited a J2EE Struts web app that was written back in 2002. There is no logging in the application other than the odd System.out.println(). I have added log4j logging so that I can write out some info to the console, but I'm concerned on how best to approach this. Any suggestions, tips, best practices would be welcome as I don't want to spend too much time adding logging to every method or class (or trying to find what places where logging would be best - ie. bad code blocks/defects). My current approach is to just add some logging to the few classes that I have been looking at to understand the code, but are there a few key places where I can add logging to maximize my use of adding log4j?

  • Storing information in the DOM?

    - by John
    Im making a small private message application in the form of a phone. Ten messages are shown at the time. And the list of messages are scrolled up/down by hiding them. Just how bad is it to use the DOM to store information in this way. My main goal for doing this is to reduce calls to the database. And instead of making a new call all the time, it only checks if any new messages has arrived and ads the new message(s). Whats the alternative, cookies anyone? Thank you for the time

  • What is the best instance type to use for hosting a website on ec2?

    - by Josh
    Amazon offers two instance types on EC2: 1) On-Demand and 2) Reserved. After reading the docs on these, I don't really understand the difference from an end-user perspective. More specifically, I'd like to know the answer to this question: is one or the other better for web applications? Based on their names and descriptions, it seems as though on-demand instances may get wiped away from the server altogether if they're not in use which means that they need to be restarted when a request finally does come in. That seems like a pretty bad thing for a website. Am I just misinterpreting the docs? Thanks!

  • Append before parent after getSelection()

    - by sanceray3
    Hi all, I have one question. I try to develop a little WYSIWYG editor. I would like create a <h1> button which allows me to generate a <h1> title (by clicking on button after text selection in <p> element). I obtain the selection with window.getSelection().... But now, I would like to put my append("<h1>my text selected</h1>") just before the <p>. It’s my problem, because my <p> elements don’t have id or class. So do you know a means to put my append just before the <p> where my text has been selected? I don’t know if with my bad English you’ll understand me! Thanks very much for your help.

    what is the right way to setup VisualStuio 2010 for working with *.cl files? I have added *.cl under Tool/Text editor/File extensions and copied usertype.dat into the common7/ide folder, but VS underlines keywords like float4 or cross. Is it necessary to add some key in registry or can somebody propose a tutorial? Thanks in advance. PS i have already asked similar question old one question, but now i am looking explicit for a solution with vs2010. It is not bad, but really nerves and deflects me from programming tasks.
