  • Static initialization of a struct with class members

    - by JS Bangs
    I have a struct that's defined with a large number of vanilla char* pointers, but also an object member. When I try to statically initialize such a struct, I get a compiler error. typedef struct { const char* pszA; // ... snip ... const char* pszZ; SomeObject obj; } example_struct; // I only want to assign the first few members, the rest should be default example_struct ex = { "a", "b" }; SomeObject has a public default constructor with no arguments, so I didn't think this would be a problem. But when I try to compile this (using VS), I get the following error: error C2248: 'SomeObject::SomeObject' : cannot access private member declared in class 'SomeObject' Any idea why?

  • Class properties vs NSArray / NSDictionary

    - by Frank Martin
    I want a custom class object to hold data and have somehow the feeling that creating about 80 properties is not the best way of doing it. Most of the properties would be bool values, so i'm thinking about creating Arrays (keys / values) or (probably better) a NSDictionary attached to the object for holding the data. Does that make sense or should i stay with the properties? Extra: Are there general pros and cons for the different approaches? And what keywords / concepts do i have to search for to find discussions about that somehow general question? Thanks in advance

  • A better name for INeedSomething... ?

    - by Daniel Severin
    I was trying pick a name for an interface through which I can pass something into an object like: If the object is INeedX then SetX(some x) method will be called; If the object is INeedY then SetY(some y) method will be called; and so on. (funny as hell, I know :) ) I try to find a different name for this kind of interfaces but I can't figure this out. Does anybody have an idea how to name the INeedSomething interface ?

  • C++ new memory allocation fragmentation

    - by tamulj
    I was trying to look at the behavior of the new allocator and why it doesn't place data contiguously. My code: struct ci { char c; int i; } template <typename T> void memTest() { T * pLast = new T(); for(int i = 0; i < 20; ++i) { T * pNew = new T(); cout << (pNew - pLast) << " "; pLast = pNew; } } So I ran this with char, int, ci. Most allocations were a fixed length from the last, sometimes there were odd jumps from one available block to another. sizeof(char) : 1 Average Jump: 64 bytes sizeof(int): 4 Average Jump: 16 sizeof(ci): 8 (int has to be placed on a 4 byte align) Average Jump: 9 Can anyone explain why the allocator is fragmenting memory like this? Also why is the jump for char so much larger then ints and a structure that contains both an int and char.

  • Minimize the sequence by putting appropriate operations ' DP'

    - by Vikas
    Given a sequence,say, 222 We have to put a '+' or '* ' between each adjacent pair. '* ' has higher precedence over '+' We have to o/p the string whose evaluation leads to minimum value. O/p must be lexicographically smallest if there are more than one. inp:222 o/p: 2*2+2 Explaination: 2+2+2=6 2+2*2=6 2*2+2=6 of this 3rd is lexicographically smallest. I was wondering how to construct a DP solution for this.

  • Add another class to a div with javascript

    - by zac
    I have a function that checks the age of a form submission and then returns new content in a div depending on their age. right now I am just using getElementById to replace the html content. BUt I think would work better for me if I could also add a class to a div as well. So for example I have.. if (under certain age) { document.getElementById('hello').innerHTML = "<p>Good Bye</p>"; createCookie('age','not13',0) return false; } else { document.getElementById('hello').innerHTML = "<p>Hello</p>"; return true; } What I would like to do is have everything in a div and if return false then that div disappears and is replaced with other content.. can I get any ideas on a good way to achieve this with pure javascript. I dont want to use jQuery for this particular function.

  • C#. Where struct methods code kept in memory?

    - by maxima120
    It is somewhat known where .NET keeps value types in memory (mostly in stack but could be in heap in certain circumstances etc)... My question is - where is the code of the struct? If I have say 16 byte of data fields in the struct and a massive computation method in it - I am presuming that 16 byte will be copied in stack and the method code is stored somewhere else and is shared for all instances of the struct. Are these presumptions correct?

  • Object model design choice

    - by spinon
    I am currently working on a ASP.NET MVC reporting application using C#. This is a redesign from a PHP application that was just initially thrown together and is now starting to gain some more traction. SowWe are in the process of reworking the backend to have a more OO approach. One of the descisions I am currently wrestling with is how to structure the domain objects. Since 95% of the site is readonly I am not sure if the typical approaches are practical. Should I create domain objects for the primary pieces of the application (ticket, assignment, assignee) and then create static methods off of these areas to pull the reporting data? Or should I just skip that part and create the chart data classes and have some get method off of these classes? It's not a real big application and currenlty I am the only one developing on it. But I feel torn as to which approach. I feel that the first one is the better choice but maybe overkill given that the majority of uses is for aggregate reporting. Anybody have some good insight on why I should go one way or another?

  • Java: limit to nest classes?

    - by HH
    A very poor style to code but sometimes unavoidable. It is an extreme example. So is there some limit for nesting classes? are they equivalent? how do you deal with such situations? Create library? Code new FileObject().new Format().new Words().new Some().new Continue someThing; ((((new FileObject()).new Format()).new Words()).new Some()).new Continue someThing;

  • what is the underlying data structure of a set c++?

    - by zebraman
    I would like to know how a set is implemented in C++. If I were to implement my own set container without using the STL provided container, what would be the best way to go about this task? I understand STL sets are based on the abstract data structure of a binary search tree. So what is the underlying data structure? An array? Also, how does insert() work for a set? How does the set check whether an element already exists in it? I read on wikipedia that another way to implement a set is with a hash table. How would this work?

  • Class works without declaring variables?

    - by Maxim Droy
    I'm learned php as functional and procedure language. Right now try to start learn objective-oriented and got an important question. I have code: class car { function set_car($model) { $this->model = $model; } function check_model() { if($this->model == "Mercedes") echo "Good car"; } } $mycar = new car; $mycar->set_car("Mercedes"); echo $mycar->check_model(); Why it does work without declaration of $model? var $model; in the begin? Because in php works "auto-declaration" for any variables? I'm stuck

  • C++ function will not return

    - by Mike
    I have a function that I am calling that runs all the way up to where it should return but doesn't return. If I cout something for debugging at the very end of the function, it gets displayed but the function does not return. fetchData is the function I am referring to. It gets called by outputFile. cout displays "done here" but not "data fetched" I know this code is messy but can anyone help me figure this out? Thanks //Given an inode return all data of i_block data char* fetchData(iNode tempInode){ char* data; data = new char[tempInode.i_size]; this->currentInodeSize = tempInode.i_size; //Loop through blocks to retrieve data vector<unsigned int> i_blocks; i_blocks.reserve(tempInode.i_blocks); this->currentDataPosition = 0; cout << "currentDataPosition set to 0" << std::endl; cout << "i_blocks:" << tempInode.i_blocks << std::endl; int i = 0; for(i = 0; i < 12; i++){ if(tempInode.i_block[i] == 0) break; i_blocks.push_back(tempInode.i_block[i]); } appendIndirectData(tempInode.i_block[12], &i_blocks); appendDoubleIndirectData(tempInode.i_block[13], &i_blocks); appendTripleIndirectData(tempInode.i_block[14], &i_blocks); //Loop through all the block addresses to get the actual data for(i=0; i < i_blocks.size(); i++){ appendData(i_blocks[i], data); } cout << "done here" << std::endl; return data; } void appendData(int block, char* data){ char* tempBuffer; tempBuffer = new char[this->blockSize]; ifstream file (this->filename, std::ios::binary); int entryLocation = block*this->blockSize; file.seekg (entryLocation, ios::beg); file.read(tempBuffer, this->blockSize); //Append this block to data for(int i=0; i < this->blockSize; i++){ data[this->currentDataPosition] = tempBuffer[i]; this->currentDataPosition++; } data[this->currentDataPosition] = '\0'; } void outputFile(iNode file, string filename){ char* data; cout << "File Transfer Started" << std::endl; data = this->fetchData(file); cout << "data fetched" << std::endl; char *outputFile = (char*)filename.c_str(); ofstream myfile; myfile.open (outputFile,ios::out|ios::binary); int i = 0; for(i=0; i < file.i_size; i++){ myfile << data[i]; } myfile.close(); cout << "File Transfer Completed" << std::endl; return; }

  • PHP class referencing confusion across multiple files

    - by DssTrainer
    I have an index.php file that has 3 includes <?php require_once('mod.php'); $mod = new Mod(); require_once('start.php'); require_once('tools.php'); ....some code.... ?> I need to be able to reference the $mod object inside the start.php and tools.php. How do I pass that object to be referenced by those 2 other require files? Basically the mod.php is a class that has an array list generated in its __construct(). I want to use that array list data inside the startup.php and tools.php file but not sure how to pass in the existing one without calling "new" inside both of those files separately which doesn't do what I need since it resets everything. Thanks!

  • How to access controls collection of dynamically loaded aspx page?

    - by Naasir
    Let's say I have two webforms, A.aspx and B.aspx, where B.aspx contains some simple web controls such as a textbox and a button. I'm trying to do the following: When A.aspx is requested, I want to dynamically call and load B.aspx into memory and output details of all the controls contained in B.aspx. Here is what I tried in the codebehind for A.aspx: var compiledType = BuildManager.GetCompiledType("~/b.aspx"); if (compiledType != null) { var pageB = (Page)Activator.CreateInstance(compiledType); } foreach (var control in pageB.Controls) { //output some details for each control, like it's name and type... } When I try the code above, the controls collection for pageB is always empty. Any ideas on how I can get this to work? Some other important details: both webforms utilize a master page (so the web controls in b.aspx are actually placed within a "content" tag) I've also tried using BuildManager.CreateInstanceFromVirtualPath. No luck.

  • Plugin architecture in C using libdl

    - by LukeN
    I've been toying around, writing a small IRC framework in C that I'm now going to expand with some core functionality - but beyond that, I'd like it to be extensible with plugins! Up until now, whenever I wrote something IRC related (and I wrote a lot, in about 6 different languages now... I'm on fire!) and actually went ahead to implement a plugin architecture, it was inside an interpreted language that had facilities for doing (read: abusing) so, like jamming a whole script file trough eval in Ruby (bad!). Now I want to abuse something in C! Basically there's three things I could do define a simple script language inside of my program use an existing one, embedding an interpreter use libdl to load *.so modules on runtime I'm fond of the third one and raather avoid the other two options if possible. Maybe I'm a masochist of some sort, but I think it could be both fun and useful for learning purposes. Logically thinking, the obvious "pain-chain" would be (lowest to highest) 2 - 1 - 3, for the simple reason that libdl is dealing with raw code that can (and will) explode in my face more often than not. So this question goes out to you, fellow users of stackoverflow, do you think libdl is up to this task, or even a realistic thought?

  • actionscript 3 website load movieclips (frames) from library

    - by steve
    Here is my current code that doesn't function: import flash.display.*; import fl.transitions.*; import flash.events.MouseEvent; stop(); var contentBox:MovieClip = new MovieClip(); contentBox.width = 400; contentBox.height = 500; contentBox.x = 400; contentBox.y = 0; var closeBtn:close_btn = new close_btn(); closeBtn.x = 850; closeBtn.y = 15; var bagLink:MovieClip = new bag_link_mc(); bagLink.x = 900; bagLink.y = 0; menu_bag_button.addEventListener(MouseEvent.CLICK, bagClick); function bagClick(event:MouseEvent):void{ if(MovieClip(root).currentFrame == 835) { } else { MovieClip(root).addChild (contentBox); MovieClip(root).contentBox.addChild (bagLink); MovieClip(root).contentBox.addChild (closeBtn); MovieClip(root).gotoAndPlay(806); } } closeBtn.addEventListener(MouseEvent.CLICK, closeBag); function closeBag (event:MouseEvent):void{ MovieClip(root).removeChild(contentBox); MovieClip(root).gotoAndPlay(850); } I don't know ActionScript at all, so this may be the complete wrong way of approaching it. The setup is as follows: site loads, there's a big menu in the center (frame 805). When you click on a menu item from there, the whole menu moves to the side, and the right side I want a "contentBox" movieclip, filled with "bagLink" (which is site content) and to have a close button (closeBtn.) It also needs to know that if you click the same link again on the left side that it doesn't reanimate, it just stays (which I achieved with the "if" statement.) Finally, if someone clicks another link, it needs to clear "contentBox" and refill it with whatever movieClip that was clicked. I know this is a lot to ask, but I'm in dire need of help as this is due on Wednesday...
