• Which design is better (OO Design)?

  - by Tattat

  I have an "Enemy" object, that have many "gun" . Each "gun" can fire "bullet". Storing "gun" is using an array. when the "gun" is fired, the "bullet" will be created. And the enemy object will have an array to store the "bullet". So, I am thinking about the fire method. I am think making a firebulletFromGun in the "enemy". It need have a parameter: "gun". while this method is called. The "enemy" 's bullet will be added in the Array. Another design is writing the fire method in the "gun". The "enemy" use the "gun"'s fire method. And the "gun" will return a "bullet" object, and it will be added in the Array of "enemy". Both method can work, but which way is better? or they are similar the same? plx drop ur ideas/suggestions. thz.

• How do I cast a void pointer to a struct in C?

  - by Rowhawn

  In a project I'm writing code for, I have a void pointer, "implementation", which is a member of a "Hash_map" struct, and points to an "Array_hash_map" struct. The concepts behind this project are not very realistic, but bear with me. The specifications of the project ask that I cast the void pointer "implementation" to an "Array_hash_map" before I can use it in any functions. My question, specifically is, what do I do in the functions to cast the void pointers to the desired struct? Is there one statement at the top of each function that casts them or do I make the cast every time I use "implementation"? Here are the typedefs the structs of a Hash_map and Array_hash_map as well as a couple functions making use of them. typedef struct { Key_compare_fn key_compare_fn; Key_delete_fn key_delete_fn; Data_compare_fn data_compare_fn; Data_delete_fn data_delete_fn; void *implementation; } Hash_map; typedef struct Array_hash_map{ struct Unit *array; int size; int capacity; } Array_hash_map; typedef struct Unit{ Key key; Data data; } Unit; functions: /* Sets the value parameter to the value associated with the key parameter in the Hash_map. */ int get(Hash_map *map, Key key, Data *value){ int i; if (map == NULL || value == NULL) return 0; for (i = 0; i < map->implementation->size; i++){ if (map->key_compare_fn(map->implementation->array[i].key, key) == 0){ *value = map->implementation->array[i].data; return 1; } } return 0; } /* Returns the number of values that can be stored in the Hash_map, since it is represented by an array. */ int current_capacity(Hash_map map){ return map.implementation->capacity; }

• Looping through Markers with Google Maps API v3 Problem

  - by Oscar Godson

  I'm not sure why this isn't working. I don't have any errors, but what happens is, no matter what marker I click on, it clicks the 3rd one (which is the last one out of 4 markers. Array starts at 0, obviously) and shows the number "3", which is correct for THAT one, but I'm not clicking that one. Here is most of my code, just not the array of [place-name, coordinates] (var locations, which you will see): function initialize() { var latlng = new google.maps.LatLng(45.522015,-122.683811); var settings = { zoom: 15, center: latlng, disableDefaultUI:true, mapTypeId: google.maps.MapTypeId.SATELLITE }; var map = new google.maps.Map(document.getElementById("map_canvas"), settings); var infowindow = new Array(); var marker = new Array(); for(x in locations){ console.log(x); infowindow[x] = new google.maps.InfoWindow({content: x}); marker[x] = new google.maps.Marker({title:locations[x][0],map:map,position:locations[x][1]}); google.maps.event.addListener(marker[x], 'click', function() {infowindow[x].open(map,marker[x]);}); } } initialize() The console.log output is (its correct, and what i expect): 0 1 2 3 So, any ideas?

• Excel isn't reading sql exported csv properly

  - by mhopkins321

  I have a batch file that calls sqlcmd to run a command and then export the data as a csv. When viewed in a cell the trasancted date for example shows 35:30.0 but if you click on it the formula bar shows 1/1/1900 2:45:00 PM. I need the full timestamp to show in the cell. Any ideas? The batch file is the following sqlcmd -S server -U username -P password -d database -i "D:\path\sqlScript.sql" -s "," > D:\path\report.csv -I -W -k 1 The script is the following. Now I currently have them cast as varchars, but that's simply because i've tried to change it a bit. Varchar doesn't work either. SET NOCOUNT ON; select top(10)BO.Status, cast(tradeDate AS varchar) AS Trade_Date, CAST(closingTime AS varchar) AS Closing_Time, CAST(openingTime AS varchar) AS openingTime FROM GIANT COMPLICATED JOINS OF ALL SORTS OF TABLES

• Could InAppSettingsKit do this, or is there another library?

  - by cannyboy

  I'm trying to implement a system whereby the user is initially presented with a single tablecell, in a uitableview (grouped style), within a uinavigationview. --------------- + | add record | --------------- When they click on the cell, they are pushed onto a new screen where they fill in a few textviews (perhaps imbedded in a tableview's cells) --------------- | (name) | --------------- | (phone num) | --------------- Then when they go back, they can see the new record as well as the 'add record' cell. --------------- | record 1 | --------------- + | add record | --------------- (When they go into record 1 again there would be a delete button) Is there any sample code or libraries which would achieve this? What about InAppSettingsKit? It's more the presentation I'm concerned with. I can handle the saving of data myself.

• How are two-dimensional arrays formatted in memory?

  - by Chris Cooper

  In C, I know I can dynamically allocate a two-dimensional array on the heap using the following code: int** someNumbers = malloc(arrayRows*sizeof(int*)); for (i = 0; i < arrayRows; i++) { someNumbers[i] = malloc(arrayColumns*sizeof(int)); } Clearly, this actually creates a one-dimensional array of pointers to a bunch of separate one-dimensional arrays of integers, and "The System" can figure you what I mean when I ask for: someNumbers[4][2]; But when I statically declare a 2D array, as in the following line...: int someNumbers[ARRAY_ROWS][ARRAY_COLUMNS]; ...does a similar structure get created on the stack, or is it of another form completely? (i.e. is it a 1D array of pointers? If not, what is it, and how do references to it get figured out?) Also, when I said, "The System," what is actually responsible for figuring that out? The kernel? Or does the C compiler sort it out while compiling?

• Jquery interactive table - multiple instance problem

  - by petejm

  Hello forgive me if i use the wrong terminology and the messiness of this code it is the first time I have used jquery. I am making an interactive table-product selector. Compatible systems run along the top and colour choices down the left. The table works by seeing if there is a cell is empty in a html table. If the cell is empty then that is a compatible system and a circle image is in that cell and it is selectable. When selected the product code is generated (by looking at the colour value and system name) and the relevant resource download pack can be downloaded. This works 'fine' when on its own on a page however when I have multiple instances of it on one page they interfere with each other. Only the first one works and clicking in the 2nd 3rd etc table updates the first one. I need these to function independant of each other. I believe the problem is centering around the (this) command working across all of the tables but I can't quite figure this out with what I know of jquery. <script type="text/javascript">// <![CDATA[ jQuery(document).ready(function($j){ $j(document).ready(function() { jQuery.noConflict() (function(){ $j(".options").each(function() { // current td element var tx = $j(this); // do it once only var val = tx.text(); tx.css('background', val ==1 ? '' : 'url(circ.png)'); }); $j("#para").text('').append("Please make a selection");; $j(".options").click(function(e) { $j(".options").each(function() { // current td element var tx = $j(this); // do it once only var val = tx.text(); tx.css('background', val ==1 ? '' : 'url(circ.png)'); }); var ProductCode = 241; var currentCellText = $j(this).text(); var LeftCellText = $j(this).prev().text(); var RightCellText = $j(this).next().text(); var RowIndex =$j(this).parent().parent().children().index($j(this).parent()); var ColIndex = $j(this).parent().children().index($j(this)); var RowsAbove = RowIndex; var ColName = $j(".head").children(':eq(' + ColIndex + ')').text(); var rowid = $j(this).parent().attr('id'); if(currentCellText===''){$j(this).css('background', 'url(circfill.png)'); $j("#para").text('').append( ColName +"-"+ ProductCode +"-"+ rowid +"<br />") $j("#resourcepack").text('').append("Download Selected Resource Pack") $j("#resourcepack").click(function(){ window.location = '241.zip'}); ;} else{$j("#para").text('').append("Incompatible Selection"); $j("#resourcepack").text('').append() }}); }); }); }); </script>

• Building static (but complicated) lookup table using templates.

  - by MarkD

  I am currently in the process of optimizing a numerical analysis code. Within the code, there is a 200x150 element lookup table (currently a static std::vector < std::vector < double ) that is constructed at the beginning of every run. The construction of the lookup table is actually quite complex- the values in the lookup table are constructed using an iterative secant method on a complicated set of equations. Currently, for a simulation, the construction of the lookup table is 20% of the run time (run times are on the order of 25 second, lookup table construction takes 5 seconds). While 5-seconds might not seem to be a lot, when running our MC simulations, where we are running 50k+ simulations, it suddenly becomes a big chunk of time. Along with some other ideas, one thing that has been floated- can we construct this lookup table using templates at compile time? The table itself never changes. Hard-coding a large array isn't a maintainable solution (the equations that go into generating the table are constantly being tweaked), but it seems that if the table can be generated at compile time, it would give us the best of both worlds (easily maintainable, no overhead during runtime). So, I propose the following (much simplified) scenario. Lets say you wanted to generate a static array (use whatever container suits you best- 2D c array, vector of vectors, etc..) at compile time. You have a function defined- double f(int row, int col); where the return value is the entry in the table, row is the lookup table row, and col is the lookup table column. Is it possible to generate this static array at compile time using templates, and how?

• jQuery re-checking check boxes

  - by Jacob

  Hi, I having problems with re-checking some checkboxes after and ajax call updates a table. I have a table of what the project calls 'shares'. I want to: 1) check for and save any checked shares to an array 2) Do my ajax call to update the table of shares 3) Re-check any there we checked before the ajax update. My code is not working and I can't see why? Any tips, help or advise much appreciated. // Array to hold our checked share ids var savedShareIDs = new Array(); // Add checked share ids into array $("input:checkbox[name=share_ids]:checked").each(function() { savedShareIDs.push($(this).val()); }); // Do ajax update Dajaxice.pagination_shares('Dajax.process',{'id':1, 'page':1}) // Re-check any that were checked before ajax update $("input:checkbox[name=share_ids]").each(function() { if ( $.inArray( $(this).val(), savedShareIDs) > -1 ) { $(this).attr('checked',true) } }); The problem is the checkboxes are not checking. I'm pretty sure the loop is working and the inArray check works. Just not checking the checkboxes. Can anyone see where I'm going wrong? Thanks.

There could be the situation when I update the image by editing the image and upload it with same name, now in this case the image file would be already present there, which will restrict the use of "file_exist" logic, so for these type of situations....HOW CAN I COMPARE THE TWO FILE STRUCTURE TO GET THE SYNCHRONIZATION DONE AS PER REQUIREMENT??

• Kohana 3.2 - Database Session losing data on new Page Request

  - by reado

  I've setup my dev Kohana server to use an encrypted database as the default Session type. I'm also using this in combination with Auth to implement user authentication. Right now my user's are able to authenticate correctly and the authentication keys are being stored in the session. I'm also storing additional data like the user's firstname and businessname during the login procedure. When my login function is ready to redirect the user to the user dashboard, I'm able to see all the data correctly when I do $session::instance()->as_array(); (Array ( [auth_user] => NRyk6lA8 [businessname] => Dudetown [firstname] => Matt )) As soon as I redirect the user to another page, $session::instance()->as_array(); is empty. By dumping out the Session::instance() object, I can see that the Session id's are still the same. When I look at my database table though, i dont see any session records being saved and my session table is empty. My bootstrap.php contains: Session::$default = 'database'; Cookie::$salt = 'asdfasdf'; Cookie::$expiration = 1209600; Cookie::$domain = FALSE; and my session.php config file looks like: return array( 'database' => array( 'name' => 'auth_user', 'encrypted' => TRUE, 'lifetime' => 24 * 3600, 'group' => 'default', 'table' => 'sessions', 'columns' => array( 'session_id' => 'session_id', 'last_active' => 'last_active', 'contents' => 'contents' ), 'gc' => 500, ), ); I've looked high and low for an answer.. if anyone has any suggestions, i'm all ears! Thanks!

• Message sent to deallocated instance which has never been released

  - by Jakub

  Hello, I started dealing with NSOperations and (as usual with concurrency) I'm observing strange behaviour. In my class I've got an instance variable: NSMutableArray *postResultsArray; when one button in the UI is pressed I initialize the array: postResultsArray = [NSMutableArray array]; and setup the operations (together with dependencies). In the operations I create a custom object and try to add to the array: PostResult *result = [[PostResult alloc] initWithServiceName:@"Sth" andResult:someResult]; [self.postResultsArray addObject:result]; and while adding I get: -[CFArray retain]: message sent to deallocated instance 0x3b40c30 which is strange as I don't release the array anywhere in my code (I did, but when the problem started to appear I commented all the release operations to be sure that they are not the case). I also used to have @synchronized section like below: PostResult *result = [[PostResult alloc] initWithServiceName:@"Sth" andResult:someResult]; @synchronized (self.postResultsArray) { [self.postResultsArray addObject:result]; } but the problem was the same (however, the error was for the synchronized operation). Any ideas what I may be doing wrong?

• Adding Insert Row in tableView

  - by user333624

  Hello everyone, I have a tableView that loads its data directly from a Core Data table with a NSFetchedResultsController. I'm not using an intermediate NSMutableArray to store the objects from the fetch results; I basically implemented inside my UITableViewController the protocol method numberOfRowsInSection and it returns the numberOfObjects inside a NSFetchedResultsSectionInfo. id <NSFetchedResultsSectionInfo> sectionInfo = [[fetchedResultsController sections] objectAtIndex:section]; and then I configure the cell content by implementing configureCell:atIndexPath and retrieving object info from the fetchedResultController but right now I have a generic configuration for any object (to avoid complications) cell.textLabel.text = @"categoria"; I also have a NavigationBar with a custom edit button at the right that loads my own selector called customSetEditing. What I'm trying to accomplish is to load an "Insert Cell" at the beginning of the tableView so when I tap it, it creates a new record. This last part is easy to implement the problem is that I dont's seem to be able to load the insert row or any row when I tap on the navigation bar edit button. this is the code for my customSetEditing: - (void) customSetEditing { [super setEditing:YES animated:YES]; [self.tableView setEditing:YES animated:YES]; [[self tableView] beginUpdates]; //[[self tableView] beginUpdates]; UIBarButtonItem *customDoneButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(customDone)]; [self.navigationItem.rightBarButtonItem release]; self.navigationItem.rightBarButtonItem = customDoneButtonItem; //[categoriasArray insertObject:[NSNull null] atIndex:0]; NSMutableArray *indexPaths = [[NSMutableArray alloc] initWithObjects:[NSIndexPath indexPathForRow:0 inSection:0],nil ]; [self.tableView insertRowsAtIndexPaths:indexPaths withRowAnimation:UITableViewRowAnimationTop]; //[indexPaths release]; [self.tableView reloadData];} Before adding the:[self.tableView reloadData]; I was getting an out of bounds error plus a program crash and although the program is not crashing it is not loading anything. I have seen many examples of similar situations in stackoverflow (by the way is an excellent forum with very helpful and nice people) none of the examples seems to work for me. Any ideas?

• Ruby Challenge - efficiently change the last character of every word in a sentence to a capital

  - by emson

  Hi All I recently was challenged to write some Ruby code to change the last character of every word in a sentence into a capital. Such that the string: "script to convert the last letter of every word to a capital" becomes "scripT tO converT thE lasT letteR oF everY worD tO A capitaL" This was my optimal solution however I'm sure you wizards have much better solutions and I would be really interested to hear them. "script to convert the last letter of every word to a capital".split.map{|w|w<<w.slice!(-1).chr.upcase}.join' ' For those interested as to what is going on here is an explanation. split will split the sentence up into an array, the default delimiter is a space and with Ruby you don't need to use brackets here. map the array from split is passed to map which opens a block and process each word (w) in the array. the block slice!(s) off the last character of the word and converts it to a chr (a character not ASCII code) and then capitalises upcase it. This character is now appended << to the word which is missing the sliced last letter. Finally the array of words is now join together with a ' ' to reform the sentence. Enjoy

• Reload table view in real time

  - by Lucas Vallim da Costa

  The app receives a UILocalNotification, but if the user is at the UITableViewController at the fire time, the table view (containing the scheduled notifications) does not reload. The user has to get out of that view and load the view again so that the cells are loaded and, as the notification was already fired, it will not be displayed on any cell of that table view. Problem is: If the user touches the specific tableView cell that contained the notification that just fired, the app crashes, cause the notification is not there anymore. I've implemented the - (void)reloadData in every place possible, and it still doesn't load in real time. What would be a better solution for this? Other detail, how can I push a specific view after the notification is displayed (when the user slides the app icon when the phone is locked)? Any help will be truly appreciated, since theres are the last details remaining to publish my first App.

• Filtering out specific objects from a search query in Alfresco using Java

  - by Snowright

  I have a HashSet containing all groups I've retrieved from my database. I've been asked to filter this result by removing two specific groups. It seems trivial but I can't seem to come up with a solid solution for storing the specific groups I want to filter out. My idea is to just create an array containing references to the two groups I need to filter out. I can then filter out my search query with whatever is in the array. My concern is that in the future they may ask to filter out more groups and maybe an array may not be a good idea. //Creates the array containing groups to filter out String[] hiddenGroups = {"group1","group2"}; //retrieves all groups Set<String>allGroups = new HashSet<String>(); allGroups.addAll(authorityService.getAllAuthorities(AuthorityType.GROUP); List<String>results = new ArrayList<String>(); //filters out specified groups for (String group : allGroups) { boolean isHidden = false; for (String hiddenGroup : hiddenGroups) { if (hiddenGroup.equalsIgnorecase(group)) { isHidden = true; } } if (!isHidden){ results.add(group); } }

• PHP question about global variables and form requests

  - by user220201

  Hi, This is probably a stupid question but will ask anyway sine I have no idea. I have written basic php code which serve forms. Say I have a login page and I serve it using the login.php page and it will be called in the login.html page like this - <form action="login.php" method="post"> By this it is also implied that every POST needs its own php file, doesn't it? This kind of feels weird. Is there a way to have a single file, say code.php, and just have each of the forms as functions instead? EDIT: Specifically, say I have 5 forms that are used one after the other in my application. Say after login the user does A, B, C and D tasks each of which are sent to the server as a POST request. So instead of having A.php, B.php, C.php and D.php I would like to have a single code.php and have A(), B(), C() and D() as functions. Is there a way to do this? Also on the same note, how do I deal with say a global array (e.g. an array of currently logged in users) across multiple forms? I want to do this without writing to a DB. I know its probably better to write to a DB and query but is it even possible to do it with a global array? The reason I was thinking about having all the form functions in one file is to use a global array. Thanks, - Pav

  I have the following un my applicationDidFinishLaunching method UIImage *image2 = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"image2.jpg" ofType:nil]]; view2 = [[UIImageView alloc] initWithImage:image2]; view2.hidden = YES; [containerView addSubview:view2]; I'm simply adding an image to a view. But because I need to add 30-40 images I need to wrap the above in a function (which returns a UIImageView) and then call it from a loop. This is my first attempt at creating the function -(UIImageView)wrapImageInView:(NSString *)imagePath { UIImage *image = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:imagePath ofType:nil]]; UIImageView *view = [[UIImageView alloc] initWithImage:image]; view.hidden = YES; } And then to invoke it I have the following so far, for simplicity I am only wrapping 3 images //Create an array and add elements to it NSMutableArray *anArray = [[NSMutableArray alloc] init]; [anArray addObject:@"image1.jpg"]; [anArray addObject:@"image2.jpg"]; [anArray addObject:@"image3.jpg"]; //Use a for each loop to iterate through the array for (NSString *s in anArray) { UIImageView *wrappedImgInView=[self wrapImage:s]; [containerView addSubview:wrappedImgInView]; NSLog(s); } //Release the array [anArray release]; I have 2 general questions 1-Is my approach correct?, ie following best practices, for what I am trying to do (load a multiple number of images(jpgs, pngs, etc.) and adding them to a container view) 2-For this to work properly with a large number of images, do I need to keep my array creation separate from my method invocation? Any other suggestions welcome!
