  • Should we or should we not check in the classes folder in WEB-INF directory into SVN?

    - by Vatsala
    I use SVN, and am learning how to use it along with eclipse IDE. The first time I add classes to my package, there is no problem, the generated class files get into SVN smoothly. The moment I edit them, I get this message - "WEB-INF/classes" is obstructed. I try the "clean-up" command and the clean up command says "WEB-INF/classes" folder is locked. I use TortoiseSVN as my SVN client. I know why this is happening. It probably because the Eclipse overwrites all the files while generating classes and then causes this - Is it inappropriate to commit the class files into SVN? If not, what should I do to commit these class files smoothly?

  • Determining the word width in C

    - by das_weezul
    Hi! I'm learning C right now and so I'm fiddling about with pointers. Is there a way to determine the word width of the CPU in C because I'm writing a small program which prints it's own stack (Because I'm curious how it is structured), so that information would come in handy. Right now I'm using an int pointer, as an integer is 4 Bytes wide and I'm using a 32-bit Intel Atom CPU. Thanks in advance, C gurus ;o)

  • accessing nth element (value) of a vector after sorting

    - by memC
    dear experts, This question is an extension of this question I asked. I have a std::vector vec_B.which stores instances of class Foo. The order of elements in this vector changes in the code. Now, I want to access the value of the current "last element" or current 'nth' element of the vector. If I use the code below to get the last element using getLastFoo() method, it doesn't return the correct value. For example, to begin with the last element of the vector has Foo.getNumber() = 9. After sorting it in descending order of num, for the last element, Foo.getNumber() = 0. But with the code below, it still returns 9.. that means it is still pointing to the original element that was the last element. What change should I make to the code below so that "lastFoo" points to the correct last element? class Foo { public: Foo(int i); ~Foo(){}; int getNum(); private: int num; }; Foo:Foo(int i){ num = i; } int Foo::getNum(){ return num; } class B { public: Foo* getLastFoo(); B(); ~B(){}; private: vector<Foo> vec_B; }; B::B(){ int i; for (i = 0; i< 10; i++){ vec_B.push_back(Foo(i)); } // Do some random changes to the vector vec_B so that elements are reordered. For // example rearrange elements in decreasing order of 'num' //... } Foo* B::getLastFoo(){ &vec_B.back(); }; int main(){ B b; Foo* lastFoo; lastFoo = b.getLastFoo() cout<<lastFoo->getNumber(); return 0; }

  • How to set a predefined value in a form in Rails

    - by marco
    So I just got started in Rails, and I'm trying to create an Object (a book_loan in my case) with a Form. The thing is that I get to this form by clicking on a book, so I pass the book_id as a parameter, like localhost:3000/loans/new?id=1. Now I don't want the user to be able to set the book id field in the form, since I already know the id. So my question is how to set the value in the form. I have been trying things like: <% form_for(@loan) do |f| %> <%= f.error_messages %> ... <%= @loan.book_id = params[:id] %> <%= f.submit 'Create' %> <% end %> without any success. Does anybody have a hint for me?

  • C++ bughunt - High-score insertion in a vector crashes the program

    - by Francisco P.
    Hello, everyone! I have a game I'm working on. My players are stored in a vector, and, at the end of the game, the game crashes when trying to insert the high-scores in the correct positions. Here's what I have (please ignore the portuguese comments, the code is pretty straightforward :P): //TOTAL_HIGHSCORES is the max. number of hiscores that i'm willing to store. This is set as 10. bool Game::updateHiScores() { bool stopIterating; bool scoresChanged = false; //Se ainda nao existirem TOTAL_HISCORES melhores pontuacoes ou se a pontuacao for melhor que uma das existentes for (size_t i = 0; i < players.size(); ++i) { //&& !(players[i].isAI()) if (players[i].getScoreValue() > 0 && (hiScores.size() < TOTAL_HISCORES || hiScores.back() < players[i].getScore())) { scoresChanged = true; if(hiScores.empty() || hiScores.back() >= players[i].getScore()) hiScores.push_back(players[i].getScore()); else { //Ciclo que encontra e insere a pontuacao no lugar desejado stopIterating = false; for(vector<Score>::iterator it = hiScores.begin(); it < hiScores.end() && !(stopIterating); ++it) { if(*it <= players[i].getScore()) { //E inserida na posicao 'it' o Score correspondente hiScores.insert(it, players[i].getScore()); //Verifica se o comprimento do vector esta dentro do desejado, se nao estiver, este e rectificado if (hiScores.size() > TOTAL_HISCORES) hiScores.pop_back(); stopIterating = true; } } } } } if (scoresChanged) sort(hiScores.begin(), hiScores.end(), higher); return scoresChanged; } What am I doing wrong here? Thanks for your time, fellas.

  • Routing Skype call to another Voip company

    - by Anarchist
    Hello, As my project to do over this summer I would like to create a program that answers a Skype call using the Skype API and allows a user to connect to another VOIP provider (through SIP) and make calls by dialling through the client callers Skype application. I understand that the Skype API allows me to answer and receive keypad input, but I'm stuck on actually sending the sound of the call to a SIP client. Is there an API/library that would allow me to take the Skype receiving audio as input in the SIP client? Is this even possible? I'm not tied to a language but I had planned on using Python. Thanks.

  • PHP Session / Array Problem accesing

    - by Chris
    Hello, I have a form that certain data, which then gets calculated and gets displayed in a table. All the data gets saved in a 2 dimensional array. Every time i go back to the form the new data gets saved in the array. That data will be displayed in the next table row and so on. I have used print_r($_Session) and everything gets properly saved in the array. Although i have no idea how to acces the session variables area, floor, phone, network etc wich are now in the array. Without arrays i stored them in a variable for example $phone , and did calculations with it. But now when i use the arrays, i keep on getting undefined index phone etc... How can i acces these variables, been looking at this for hours without getting any closer to a solution. Any help much appreciated. Regards. First page: if (empty ($ _POST)) ( Mode = $ name $ _POST ['state name']; $ Area = $ _POST ['size']; $ Floor = isset ($ _POST ['floor'])? $ _POST ['Floor'] 0, / / if checkbox checked value 1 else 0 $ Phone = isset ($ _POST ['phone'])? $ _POST ['Phone']: 0; $ Network = isset ($ _POST ['network'])? $ _POST ['Network']: 0; / / Control surface if (is_numeric ($ area)) / / OK ( if (isset ($ _SESSION ['table'])) ( / / Create a new row to the existing session table $ Table = $ _SESSION ['table']; $ Number = count ($ table); $ Table [$ count] [0] = $ file name; $ Table [$ count] [1] = $ size; $ Table [$ count] [2] = $ floor; $ Table [$ count] [3] = $ phone; $ Table [$ count] [4] = $ network; $ _SESSION ['Table'] = $ table; ) else ( / / Create the session table $ Table [0] [0] = $ file name; $ Table [0] [1] = $ size; $ Table [0] [2] = $ floor; $ Table [0] [3] = $ phone; $ Table [0], [4] $ = network; $ _SESSION ['Table'] = $ table; ) header ("Location: ExpoOverzicht.php"); ) else ( echo "<h1> surface Wrong - New try </ h1>"; ) ) When i made the php code withotu the arrays i declared like this, and it worked fine. But now there in the array, and i have no idea how to "acces them" $standnaam = $_SESSION["standnaam"]; $oppervlakte = $_SESSION["oppervlakte"]; $verdieping = $_SESSION["verdieping"]; $telefoon = $_SESSION["telefoon"]; $netwerk = $_SESSION["netwerk"];

  • Android card based game, need help to start

    - by user331296
    Hello, I'm just setting out in android development. I want to make a kind of card based game. I'm just looking for suggestions really on how I might start it. I know I have to make the menu layout and view, then use an Intent from that to get to the main game view. My sticking points are: -There's going to be a deck of cards. It's going to be a set number so I was thinking I could just have each card defined as a button in the layout. I don't know if that is the right way to do it though. -Storage of card details. I'm thinking of using an xml file to store these. Thanks in advance.

  • Error handling with Python + Pylons

    - by ensnare
    What is the proper way to handle errors with Python + Pylons? Say a user sets a password via a form that, when passed to a model class via the controller, throws an error because it's too short. How should that error be handled so that an error message gets displayed on the web page rather than the entire script terminating to an error page? Should there be any error handling in the controller itself? I hope I am explaining myself clearly. Thank you.

  • PC to Macbook Pro Transition - Getting (re)started?

    - by Torus Linvald
    I'm in my second computer science course right now. I've enjoyed programming so far, but really have just scraped my way by. I've not done much programming outside of required class work. For similar reasons, I never really invested in downloading/learning software to help me program (IDE's, editors, compilers, etc). I know it sounds tedious, but my current setup is: notepad++ for coding; Filezilla to transfer .cpp & .h files to school's aludra/unix and compiling; unix tells me where my bugs are and I go back to notepad++ to debug; repeat until done. This isn't fun - and I know it could be easier. But I put it off knowing that I was soon going to switch to a Mac. And, tomorrow, I'm switching. So... How should I set up my Macbook for the best programming experience? What IDEs and editors and debuggers and so on should I download? How will Mac programming differ from PC? I'm open to all ideas and comments, even the most basic. (Background - I'm learning/programming in C++ right now. Next semester, my classes switch to Java. I'm also going to take a class in web development, with HTML/CSS/Javascript/PHP. My new laptop will be a late 2009 Macbook Pro with Leopard, or maybe Snow Leopard. Free would be preferrable for all programs.) Thank you all.

  • How to improve the speed of a loop containing a sqlalchemy query statement as conditional

    - by LtPinback
    This loop checks if a record is in the sqlite database and builds a list of dictionaries for those records that are missing and then executes a multiple insert statement with the list. This works but it is very slow (at least i think it is slow) as it takes 5 minutes to loop over 3500 queries. I am a complete newbie in python, sqlite and sqlalchemy so I wonder if there is a faster way of doing this. list_dict = [] session = Session() for data in data_list: if session.query(Class_object).filter(Class_object.column_name_01 == data[2]).filter(Class_object.column_name_00 == an_id).count() == 0: list_dict.append({'column_name_00':a_id, 'column_name_01':data[2]}) conn = engine.connect() conn.execute(prices.insert(),list_dict) conn.close() session.close() edit: I moved session = Session() outside the loop. Did not make a difference.
