• PHP: How to automate building a 100 <UL>/<LI> menuitems, while keeping the Menu Structure File Flat / Simply Managable?

  - by Sam

  Above: current "stupid" menu. (entire ul/li menu for javascript menu system) + (some li lines as page-specific submenu) Hi folks! With passion for automation and elegancy, but limited knowledge/knowhow, im stuck with "my hands in my hair" as we Dutch say, for my current menu system works perfectly, but is a pain in the a*s to update! So, i would appreciate it greatly, if you can suggest how to automate this in php: how to let the php generate the html menu code basing on a flat menu input file with TABS indented. OLD SITUATION <ul> <!-- about 100 of these <li>....</li> lines --> <li><a href="carrot.php"><p class="mnu" style="background-position:0 -820px"><? echo __("carrot juice") ?></p></a></li> <!-- lots of data, with only little bit thats really the menu itself--> </ul a javascript file reads a ul/li structure as input to build menu of format in that ul/li, the items with a hyperlink and sprite-bg position represent webpages, (inside LI) while items without hyperlink and sprite-bg are just headers of that menusection, (inside H6) to highlight the current page in the menu, the javascript menumaker uses an id number. this number corresponds to the consequtive li that is a webpage, skips h6 headers correctly. these h6 headers are only there for when importing sections of the same menu as submenu. non-li headers are not shown in menu, nore counted by the javascript menu for their ID. to know which page should be shown, i have to count from ID 0, the li items till finding the current webpage in the li structure and then manually put it in each webpage! BUT: changing an item in li order, means stupidly re-counting their entire li again! each webpage has an icon (= sprite bg-position numer), which is also used in the webpage. INTENDED RESULT I dream of, once setting what the current webpage is (e.g carrot.php) the menu system automatically "finds" and "counts" the li's and returns the id nr (for proper highlight of main menu); generates the entire menu html, and depending on which headings are set for submenu, (e.g. meals, drinks) generates those submenu (entire section below each given header); ginally adds h5 highlight inside the li of that submenu item. For the menu, i wish an easily readable, simple plain txt menu that is indented with tabs, (each tab is one depth for example) and further tabs follow for url and sprite position of icon. MY DREAM MENU-MANAGEMENT FILE |>TAB SEPARATED/INDENTED FLATMENU FILE |MUST BE CALCULATED BY PHP: |>MENUTEXT============URL=============SPRITE=====|ID===TAG================== |>about "#" -520 |00 li |> INFORMATION |—— h6 |> physical state "physical.php" -920 |01 li |> mental health "mental.php" -10 |02 li |> |>apetite "#" -1290 |03 li |> meals "#" -600 |04 li |> COLD MEAL |—— h6 |> egg salade "salad.php" -1040 |05 li |> salmon fish "salmon.php" -540 |06 li |> HOT MEAL |—— h6 |> spare ribs "spareribs.php" -120 |07 li |> di macaroni "macaroni.php" -870 |08 li |> |> drinks "#" -230 |09 li |> JUCY DRINK |—— h6 |> carrot juice "carrot.php" -820 |10 li |> mango hive "mango.php" -270 |11 li DESIRED CHRONOLOGY php outputs the entire ul/li html so the javascript can show the menu: webpage items go inside li tags, and header items go inside h6 tags, e.g. <h6>JUCY DRINK</h6> Each website page has a url filename [eg: salad.php]. Based on this given fact, the php menu generator detects the pagename, gives the IDnr of the position of that page according to the li-item nr and sets variable for javascript to highlight current menu item. the menu items below the specified headers are loaded as submenu in which the current page.php is wrapped inside h5 to highlight current page in submenu: e.g. (<li><h5><a href="carrot.php"><p>..etc..</p></h5></li> Question Which methods / steps / (chronological)ways are there for doing this? I am no good in php programming, but am learning it so please dont write any code without a line of comment why I should use that method etc. Where do I start? If I am unclear in my question, please ask. Thanks. Much appreciated!! Concrete Task List from the provided Comments/Answers, sofar: (RobertB) First, get some PHP code working that can read through a tab-delimited file and put the data into an appropriate data structure.

• How can I use curl to login multiple users from one php script

  Here is the scenario: I have configured multiple users with login names aa1, aa2 .. zz99 , all with the same password, now i want to login to a php based server with these login ID's.

• Core Data: Fetch all entities in a to-many-relationship of a particular object?

  - by Björn Marschollek

  Hi there, in my iPhone application I am using simple Core Data Model with two entities (Item and Property): Item name properties Property name value item Item has one attribute (name) and one one-to-many-relationship (properties). Its inverse relationship is item. Property has two attributes the according inverse relationship. Now I want to show my data in table views on two levels. The first one lists all items; when one row is selected, a new UITableViewController is pushed onto my UINavigationController's stack. The new UITableView is supposed to show all properties (i.e. their names) of the selected item. To achieve this, I use a NSFetchedResultsController stored in an instance variable. On the first level, everything works fine when setting up the NSFetchedResultsController like this: -(NSFetchedResultsController *) fetchedResultsController { if (fetchedResultsController) return fetchedResultsController; // goal: tell the FRC to fetch all item objects. NSFetchRequest *fetch = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Item" inManagedObjectContext:self.moContext]; [fetch setEntity:entity]; NSSortDescriptor *sort = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES]; [fetch setSortDescriptors:[NSArray arrayWithObject:sort]]; [fetch setFetchBatchSize:10]; NSFetchedResultsController *frController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetch managedObjectContext:self.moContext sectionNameKeyPath:nil cacheName:@"cache"]; self.fetchedResultsController = frController; fetchedResultsController.delegate = self; [sort release]; [frController release]; [fetch release]; return fetchedResultsController; } However, on the second-level UITableView, I seem to do something wrong. I implemented the fetchedresultsController in a similar way: -(NSFetchedResultsController *) fetchedResultsController { if (fetchedResultsController) return fetchedResultsController; // goal: tell the FRC to fetch all property objects that belong to the previously selected item NSFetchRequest *fetch = [[NSFetchRequest alloc] init]; // fetch all Property entities. NSEntityDescription *entity = [NSEntityDescription entityForName:@"Property" inManagedObjectContext:self.moContext]; [fetch setEntity:entity]; // limit to those entities that belong to the particular item NSPredicate *predicate = [NSPredicate predicateWithFormat:[NSString stringWithFormat:@"item.name like '%@'",self.item.name]]; [fetch setPredicate:predicate]; // sort it. Boring. NSSortDescriptor *sort = [[NSSortDescriptor alloc] initWithKey:@"name" ascending:YES]; [fetch setSortDescriptors:[NSArray arrayWithObject:sort]]; NSError *error = nil; NSLog(@"%d entities found.",[self.moContext countForFetchRequest:fetch error:&error]); // logs "3 entities found."; I added those properties before. See below for my saving "problem". if (error) NSLog("%@",error); // no error, thus nothing logged. [fetch setFetchBatchSize:20]; NSFetchedResultsController *frController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetch managedObjectContext:self.moContext sectionNameKeyPath:nil cacheName:@"cache"]; self.fetchedResultsController = frController; fetchedResultsController.delegate = self; [sort release]; [frController release]; [fetch release]; return fetchedResultsController; } Now it's getting weird. The above NSLog statement returns me the correct number of properties for the selected item. However, the UITableViewDelegate method tells me that there are no properties: -(NSInteger) tableView:(UITableView *)table numberOfRowsInSection:(NSInteger)section { id <NSFetchedResultsSectionInfo> sectionInfo = [[self.fetchedResultsController sections] objectAtIndex:section]; NSLog(@"Found %d properties for item \"%@\". Should have found %d.",[sectionInfo numberOfObjects], self.item.name, [self.item.properties count]); // logs "Found 0 properties for item "item". Should have found 3." return [sectionInfo numberOfObjects]; } The same implementation works fine on the first level. It's getting even weirder. I implemented some kind of UI to add properties. I create a new Property instance via Property *p = [NSEntityDescription insertNewObjectForEntityForName:@"Property" inManagedObjectContext:self.moContext];, set up the relationships and call [self.moContext save:&error]. This seems to work, as error is still nil and the object gets saved (I can see the number of properties when logging the Item instance, see above). However, the delegate methods are not fired. This seems to me due to the possibly messed up fetchRequest(Controller). Any ideas? Did I mess up the second fetch request? Is this the right way to fetch all entities in a to-many-relationship for a particular instance at all?

• Netbeans Java SE GUI Builder: private initComponents() problem

  - by maSnun

  When I build a GUI for my Java SE app with Netbeans GUI builder, it puts all the codes in the initComponents() method which is private. I could not change it to public. So, all the components are accessible only to the class containing the UI. I want to access those components from another class so that I can write custom event handlers and everything. Most importantly I want to separate my GUI code and non-GUI from each other. I can copy paste the GUI code and later make them public by hand to achieve what I want. But thats a pain. I have to handcraft a portion whenever I need to re-design the UI. What I tried to do: I used the variable identifier to make the text box public. Now how can I access the text box from the Main class? I think I need the component generated in a public method as well. I am new to Java. Any helps? Here's the sample classes: The UI (uiFrame.java) /* * To change this template, choose Tools | Templates * and open the template in the editor. */ /* * uiFrame.java * * Created on Jun 3, 2010, 9:33:15 PM */ package barcode; import java.util.logging.Level; import java.util.logging.Logger; import javax.swing.JFileChooser; import javax.swing.UIManager; import javax.swing.UnsupportedLookAndFeelException; import net.sourceforge.barbecue.output.OutputException; /** * * @author masnun */ public class uiFrame extends javax.swing.JFrame { /** Creates new form uiFrame */ public uiFrame() { try { try { // Set cross-platform Java L&F (also called "Metal") UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); } catch (ClassNotFoundException ex) { Logger.getLogger(uiFrame.class.getName()).log(Level.SEVERE, null, ex); } catch (InstantiationException ex) { Logger.getLogger(uiFrame.class.getName()).log(Level.SEVERE, null, ex); } catch (IllegalAccessException ex) { Logger.getLogger(uiFrame.class.getName()).log(Level.SEVERE, null, ex); } catch (UnsupportedLookAndFeelException ex) { Logger.getLogger(uiFrame.class.getName()).log(Level.SEVERE, null, ex); } } finally { } initComponents(); } /** This method is called from within the constructor to * initialize the form. * WARNING: Do NOT modify this code.

• More elegant way to make a C++ member function change different member variables based on template p

  - by Eric Moyer

  Today, I wrote some code that needed to add elements to different container variables depending on the type of a template parameter. I solved it by writing a friend helper class specialized on its own template parameter which had a member variable of the original class. It saved me a few hundred lines of repeating myself without adding much complexity. However, it seemed kludgey. I would like to know if there is a better, more elegant way. The code below is a greatly simplified example illustrating the problem and my solution. It compiles in g++. #include <vector> #include <algorithm> #include <iostream> namespace myNS{ template<class Elt> struct Container{ std::vector<Elt> contents; template<class Iter> void set(Iter begin, Iter end){ contents.erase(contents.begin(), contents.end()); std::copy(begin, end, back_inserter(contents)); } }; struct User; namespace WkNS{ template<class Elt> struct Worker{ User& u; Worker(User& u):u(u){} template<class Iter> void set(Iter begin, Iter end); }; }; struct F{ int x; explicit F(int x):x(x){} }; struct G{ double x; explicit G(double x):x(x){} }; struct User{ Container<F> a; Container<G> b; template<class Elt> void doIt(Elt x, Elt y){ std::vector<Elt> v; v.push_back(x); v.push_back(y); Worker<Elt>(*this).set(v.begin(), v.end()); } }; namespace WkNS{ template<class Elt> template<class Iter> void Worker<Elt>::set(Iter begin, Iter end){ std::cout << "Set a." << std::endl; u.a.set(begin, end); } template<> template<class Iter> void Worker<G>::set(Iter begin, Iter end){ std::cout << "Set b." << std::endl; u.b.set(begin, end); } }; }; int main(){ using myNS::F; using myNS::G; myNS::User u; u.doIt(F(1),F(2)); u.doIt(G(3),G(4)); } User is the class I was writing. Worker is my helper class. I have it in its own namespace because I don't want it causing trouble outside myNS. Container is a container class whose definition I don't want to modify, but is used by User in its instance variables. doIt<F> should modify a. doIt<G> should modify b. F and G are open to limited modification if that would produce a more elegant solution. (As an example of one such modification, in the real application F's constructor takes a dummy parameter to make it look like G's constructor and save me from repeating myself.) In the real code, Worker is a friend of User and member variables are private. To make the example simpler to write, I made everything public. However, a solution that requires things to be public really doesn't answer my question. Given all these caveats, is there a better way to write User::doIt?

• Passing GLatLng from array to Google

  - by E. Rose

  Hello All, To preface this, I am a complete programming amateur so this may be quite easily solved. As is though, it is frustrating me to no end. Basically, I have a database of Venue Names with GLat and GLng (other stuff too) that I am pulling down to my website based on a geolocated search. The javascript that I have pulls in a formatted subset of the database, dumps the glat and glng into an array and is supposed to take those points and plot out several markers each with an info window containing the details behind each marker. For some reason, the marker geodata is not being populated and/or is not being passed. The array is declared using [] and will not work when normally declared using (). It only brings up a map with the first value in the array and goes blank if i try to manually input later entries. There is a large block of commented out code relating to directions generation. That code worked for some reason. If anyone can tell me what I am doing wrong in rewriting it to map the markers and not give directions, please tell me. Any help would be much appreciated. var letters = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z']; google.load("maps", "2", {"other_params":"sensor=true"}); var map function initialize(){ window.map = new google.maps.Map2(document.getElementById("map")); map.addControl(new GLargeMapControl()); } google.setOnLoadCallback(initialize); function getVenueResults(_zip, _num, _remove){ var rFlag = ''; if(_remove != null){ rFlag = "&removeId=" + _remove; } var url = 'ajax/getVenues.php?zip=' + _zip + "&num=" + _num + rFlag; new Ajax.Updater('resultsContainer', url, { onComplete: processResults }); } function processResults(){ window.map.clearOverlays(); var waypoints = []; var resultsList = $$('.resultWrapper'); var stepList = $$('.resultDirections'); for(i=0; i for(i=0; i<resultsList.length; i++){ var resultsElem = resultsList[i]; resultsElem.removeClassName('firstResult'); resultsElem.removeClassName('lastResult'); if(i == 0){ resultsElem.addClassName('firstResult'); } if(i == resultsList.length - 1){ resultsElem.addClassName('lastResult'); } var insertContent = '<div class="resultDirections" id="resultDirections' + i + '"></div>'; Element.insert(resultsElem, { bottom : insertContent }) var num = resultsElem.getElementsByClassName('numHolder'); num[0].innerHTML = '<b>' + letters[i] + ".</b> "; var geolat = resultsElem.getElementsByClassName('geolat')[0].value; var geolong = resultsElem.getElementsByClassName('geolong')[0].value; var point = new GLatLng(geolat, geolong); waypoints[i] = point; } if(waypoints.length == 1){ map.setCenter(waypoints[0], 16); map.addOverlay(new GMarker(waypoints[0])); resultsElem.getElementsByClassName('numHolder')[0].innerHTML = ''; }else{ map.setCenter(waypoints[0], 16); for(j=0; j< waypoints.length; j++) { var vLoc = waypoints[j]; var vInfo = resultsElem.getElementByClassName('resultBox[j]]').innerHTML; //unfinished function to mine name out of div and make it the marker title //x = resultsElem.getElementsByTagName("b"); // for (i=0;i<x.length;i++) // //marker.value = resultsElem.getElementBy('numHolder').innerHTML var marker = createMarker(vLoc, vInfo); map.addOverlay(marker); } } function createMarker(vLoc, vInfo) { var marker = (new GMarker(vLoc)); var cont = vInfo; GEvent.addListener(marker, 'click', function() { marker.openInfoWindowHtml(cont); }); return marker; } //var directions = new GDirections(window.map, document.getElementById('directionsPanel')); //directions.loadFromWaypoints(waypoints, { travelMode: G_TRAVEL_MODE_WALKING }); //GEvent.addListener(directions, "load" , function() { // var numRoutes = directions.getNumRoutes(); // for(j=0; j< numRoutes; j++){ // var thisRoute = directions.getRoute(j); // var routeText = ''; // for(k=0; k < thisRoute.getNumSteps(); k++){ // var thisStep = thisRoute.getStep(k); // if(k != 0){ routeText += " &nbsp;||&nbsp; "; } // routeText += thisStep.getDescriptionHtml(); // } // $('resultDirections' + j).innerHTML = routeText; // } // $('resultDirections' + numRoutes).hide(); //}); } function moveUp(_obj){ var parentObj = $(_obj).up().up(); var prevSib = parentObj.previous(); prevSib.insert({before: parentObj}); processResults(); } function moveDown(_obj){ var parentObj = $(_obj).up().up(); var nextSib = parentObj.next(); nextSib.insert({after: parentObj}); processResults(); }

• Need some suggestions on my softwares architecture. [Code review]

  - by Sergio Tapia

  I'm making an open source C# library for other developers to use. My key concern is ease of use. This means using intuitive names, intuitive method usage and such. This is the first time I've done something with other people in mind, so I'm really concerned about the quality of the architecture. Plus, I wouldn't mind learning a thing or two. :) I have three classes: Downloader, Parser and Movie I was thinking that it would be best to only expose the Movie class of my library and have Downloader and Parser remain hidden from invocation. Ultimately, I see my library being used like this. using FreeIMDB; public void Test() { var MyMovie = Movie.FindMovie("The Matrix"); //Now MyMovie would have all it's fields set and ready for the big show. } Can you review how I'm planning this, and point out any wrong judgement calls I've made and where I could improve. Remember, my main concern is ease of use. Movie.cs using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Drawing; namespace FreeIMDB { public class Movie { public Image Poster { get; set; } public string Title { get; set; } public DateTime ReleaseDate { get; set; } public string Rating { get; set; } public string Director { get; set; } public List<string> Writers { get; set; } public List<string> Genres { get; set; } public string Tagline { get; set; } public string Plot { get; set; } public List<string> Cast { get; set; } public string Runtime { get; set; } public string Country { get; set; } public string Language { get; set; } public Movie FindMovie(string Title) { Movie film = new Movie(); Parser parser = Parser.FromMovieTitle(Title); film.Poster = parser.Poster(); film.Title = parser.Title(); film.ReleaseDate = parser.ReleaseDate(); //And so an so forth. } public Movie FindKnownMovie(string ID) { Movie film = new Movie(); Parser parser = Parser.FromMovieID(ID); film.Poster = parser.Poster(); film.Title = parser.Title(); film.ReleaseDate = parser.ReleaseDate(); //And so an so forth. } } } Parser.cs using System; using System.Collections.Generic; using System.Linq; using System.Text; using HtmlAgilityPack; namespace FreeIMDB { /// <summary> /// Provides a simple, and intuitive way for searching for movies and actors on IMDB. /// </summary> class Parser { private Downloader downloader = new Downloader(); private HtmlDocument Page; #region "Page Loader Events" private Parser() { } public static Parser FromMovieTitle(string MovieTitle) { var newParser = new Parser(); newParser.Page = newParser.downloader.FindMovie(MovieTitle); return newParser; } public static Parser FromActorName(string ActorName) { var newParser = new Parser(); newParser.Page = newParser.downloader.FindActor(ActorName); return newParser; } public static Parser FromMovieID(string MovieID) { var newParser = new Parser(); newParser.Page = newParser.downloader.FindKnownMovie(MovieID); return newParser; } public static Parser FromActorID(string ActorID) { var newParser = new Parser(); newParser.Page = newParser.downloader.FindKnownActor(ActorID); return newParser; } #endregion #region "Page Parsing Methods" public string Poster() { //Logic to scrape the Poster URL from the Page element of this. return null; } public string Title() { return null; } public DateTime ReleaseDate() { return null; } #endregion } } ----------------------------------------------- Do you guys think I'm heading towards a good path, or am I setting myself up for a world of hurt later on? My original thought was to separate the downloading, the parsing and the actual populating to easily have an extensible library. Imagine if one day the website changed its HTML, I would then only have to modifiy the parsing class without touching the Downloader.cs or Movie.cs class. Thanks for reading and for helping!

• Using C# to detect whether a filename character is considered international

  - by Morten Mertner

  I've written a small console application (source below) to locate and optionally rename files containing international characters, as they are a source of constant pain with most source control systems (some background on this below). The code I'm using has a simple dictionary with characters to look for and replace (and nukes every other character that uses more than one byte of storage), but it feels very hackish. What's the right way to (a) find out whether a character is international? and (b) what the best ASCII substitution character would be? Let me provide some background information on why this is needed. It so happens that the danish Å character has two different encodings in UTF-8, both representing the same symbol. These are known as NFC and NFD encodings. Windows and Linux will create NFC encoding by default but respect whatever encoding it is given. Mac will convert all names (when saving to a HFS+ partition) to NFD and therefore returns a different byte stream for the name of a file created on Windows. This effectively breaks Subversion, Git and lots of other utilities that don't care to properly handle this scenario. I'm currently evaluating Mercurial, which turns out to be even worse at handling international characters.. being fairly tired of these problems, either source control or the international character would have to go, and so here we are. My current implementation: public class Checker { private Dictionary<char, string> internationals = new Dictionary<char, string>(); private List<char> keep = new List<char>(); private List<char> seen = new List<char>(); public Checker() { internationals.Add( 'æ', "ae" ); internationals.Add( 'ø', "oe" ); internationals.Add( 'å', "aa" ); internationals.Add( 'Æ', "Ae" ); internationals.Add( 'Ø', "Oe" ); internationals.Add( 'Å', "Aa" ); internationals.Add( 'ö', "o" ); internationals.Add( 'ü', "u" ); internationals.Add( 'ä', "a" ); internationals.Add( 'é', "e" ); internationals.Add( 'è', "e" ); internationals.Add( 'ê', "e" ); internationals.Add( '¦', "" ); internationals.Add( 'Ã', "" ); internationals.Add( '©', "" ); internationals.Add( ' ', "" ); internationals.Add( '§', "" ); internationals.Add( '¡', "" ); internationals.Add( '³', "" ); internationals.Add( '­', "" ); internationals.Add( 'º', "" ); internationals.Add( '«', "-" ); internationals.Add( '»', "-" ); internationals.Add( '´', "'" ); internationals.Add( '`', "'" ); internationals.Add( '"', "'" ); internationals.Add( Encoding.UTF8.GetString( new byte[] { 226, 128, 147 } )[ 0 ], "-" ); internationals.Add( Encoding.UTF8.GetString( new byte[] { 226, 128, 148 } )[ 0 ], "-" ); internationals.Add( Encoding.UTF8.GetString( new byte[] { 226, 128, 153 } )[ 0 ], "'" ); internationals.Add( Encoding.UTF8.GetString( new byte[] { 226, 128, 166 } )[ 0 ], "." ); keep.Add( '-' ); keep.Add( '=' ); keep.Add( '\'' ); keep.Add( '.' ); } public bool IsInternationalCharacter( char c ) { var s = c.ToString(); byte[] bytes = Encoding.UTF8.GetBytes( s ); if( bytes.Length > 1 && ! internationals.ContainsKey( c ) && ! seen.Contains( c ) ) { Console.WriteLine( "X '{0}' ({1})", c, string.Join( ",", bytes ) ); seen.Add( c ); if( ! keep.Contains( c ) ) { internationals[ c ] = ""; } } return internationals.ContainsKey( c ); } public bool HasInternationalCharactersInName( string name, out string safeName ) { StringBuilder sb = new StringBuilder(); Array.ForEach( name.ToCharArray(), c => sb.Append( IsInternationalCharacter( c ) ? internationals[ c ] : c.ToString() ) ); int length = sb.Length; sb.Replace( " ", " " ); while( sb.Length != length ) { sb.Replace( " ", " " ); } safeName = sb.ToString().Trim(); string namePart = Path.GetFileNameWithoutExtension( safeName ); if( namePart.EndsWith( "." ) ) safeName = namePart.Substring( 0, namePart.Length - 1 ) + Path.GetExtension( safeName ); return name != safeName; } } And this would be invoked like this: FileInfo file = new File( "Århus.txt" ); string safeName; if( checker.HasInternationalCharactersInName( file.Name, out safeName ) ) { // rename file }

• jQuery works in FF but not in Safari

  - by Hristo

  I have some event handlers that work in FF and not in Safari. Simply put, I have a list of friends, some hard-coded, some pulled in from a database. Clicking on a buddy opens a chat window... this is much like the Facebook chat system. So in Firefox, everything works normally and as expected. In Safari, clicking on buddies that are hard-coded works fine, but clicking on buddies that are pulled in from the database doesn't pull up the chat window. <script type="text/javascript" src="js/jQuery.js"></script> <script type="text/javascript" src="js/chat.js"></script> <script type="text/javascript" src="js/ChatBar.js"></script> <script type="text/javascript" src="js/settings.js"></script> <script type="text/javascript"> var chat = new Chat(); var from = <?php echo "'" .$_SESSION['userid'] . "'"; ?>; chat.getUsers(<?php echo "'" .$_SESSION['userid'] . "'"; ?>); </script> So I load all my buddies with chat.getUsers. That function is: // get list of friends function getBuddyList(userName) { userNameID = userName; $.ajax({ type: "GET", url: "buddyList.php", data: { 'userName': userName, 'current': numOfUsers }, dataType: "json", cache: false, success: function(data) { if (numOfUsers != data.numOfUsers) { numOfUsers = data.numOfUsers; var list = "<li><span>Agents</span></li>"; for (var i = 0; i < data.friendlist.length; i++) { list += "<li><a class=\"buddy\" href=\"#\"><img alt=\"\" src=\"images/chat-thumb.gif\">"+ data.friendlist[i] +"</a></li>"; } $('#friend-list ul').append($(list)); } setTimeout('getBuddyList(userNameID)', 1000); } }); } buddyList.php just pulls in the Users from the database and returns an array with the user names. So the jQuery for clicking a buddy is: // click on buddy in #friends-panel $('#friends-panel a.buddy').click(function() { alert("Loaded"); // close #friends-panel $('.subpanel').hide(); $('#friends-panel a.chat').removeClass('active'); // if a chat window is already active, close it and deactivate $('#mainpanel li[class="active-buddy-tab"] div').not('#chat-box').removeAttr('id'); $('#mainpanel li[class="active-buddy-tab"]').removeClass('active-buddy-tab').addClass('buddy-tab'); // create active buddy chat window $('#mainpanel').append('<li class="active-buddy-tab"><a class="buddy-tab" href="#"></a><div id="chat-window"><h3><p id="to"></p></h3></div></li>'); // create name and close/minimize buttons $('.active-buddy-tab div h3 p#to').text($(this).text()); $('.active-buddy-tab div h3').append('<span class="close"> X </span><span class="minimize"> &ndash; </span>'); $('.active-buddy-tab').append('<span class="close"> X </span>'); // create chat area $('.active-buddy-tab div').append('<div id="chat-box"></div><form id="chat-message"><textarea id="message" maxlength="100"></textarea></form>'); // put curser in chat window $('.active-buddy-tab #message').focus(); // create a chat relationship return false; }); ... and the basic structure of the HTML is: <div id="footpanel"> <ul id="mainpanel"> <li id="friends-panel"> <a href="#" class="chat">Friends (<strong>18</strong>) </a> <div id="friend-list" class="subpanel"> <h3><span> &ndash; </span>Friends Online</h3> <ul> <li><span>Family Members</span></li> <!-- Hard coded buddies --> <li><a href="#" class="buddy"><img src="images/chat-thumb.gif" alt="" /> Your Friend 1</a></li> <li><a href="#" class="buddy"><img src="images/chat-thumb.gif" alt="" /> Your Friend </a></li> <!-- buddies will be added in dynamically here --> </ul> </div> </li> </ul> </div> I'm not too sure where to begin solving this issue. I thought it might be a rendering bug or something with the DOM but I've been staring at this code all day and I'm stuck. Any ideas on why it works in FF and not in Safari? btw... I'm testing on Snow Leopard. Thanks, Hristo

• Improving HTML scrapper efficiency with pcntl_fork()

  - by Michael Pasqualone

  With the help from two previous questions, I now have a working HTML scrapper that feeds product information into a database. What I am now trying to do is improve efficiently by wrapping my brain around with getting my scrapper working with pcntl_fork. If I split my php5-cli script into 10 separate chunks, I improve total runtime by a large factor so I know I am not i/o or cpu bound but just limited by the linear nature of my scraping functions. Using code I've cobbled together from multiple sources, I have this working test: <?php libxml_use_internal_errors(true); ini_set('max_execution_time', 0); ini_set('max_input_time', 0); set_time_limit(0); $hrefArray = array("http://slashdot.org", "http://slashdot.org", "http://slashdot.org", "http://slashdot.org"); function doDomStuff($singleHref,$childPid) { $html = new DOMDocument(); $html->loadHtmlFile($singleHref); $xPath = new DOMXPath($html); $domQuery = '//div[@id="slogan"]/h2'; $domReturn = $xPath->query($domQuery); foreach($domReturn as $return) { $slogan = $return->nodeValue; echo "Child PID #" . $childPid . " says: " . $slogan . "\n"; } } $pids = array(); foreach ($hrefArray as $singleHref) { $pid = pcntl_fork(); if ($pid == -1) { die("Couldn't fork, error!"); } elseif ($pid > 0) { // We are the parent $pids[] = $pid; } else { // We are the child $childPid = posix_getpid(); doDomStuff($singleHref,$childPid); exit(0); } } foreach ($pids as $pid) { pcntl_waitpid($pid, $status); } // Clear the libxml buffer so it doesn't fill up libxml_clear_errors(); Which raises the following questions: 1) Given my hrefArray contains 4 urls - if the array was to contain say 1,000 product urls this code would spawn 1,000 child processes? If so, what is the best way to limit the amount of processes to say 10, and again 1,000 urls as an example split the child work load to 100 products per child (10 x 100). 2) I've learn that pcntl_fork creates a copy of the process and all variables, classes, etc. What I would like to do is replace my hrefArray variable with a DOMDocument query that builds the list of products to scrape, and then feeds them off to child processes to do the processing - so spreading the load across 10 child workers. My brain is telling I need to do something like the following (obviously this doesn't work, so don't run it): <?php libxml_use_internal_errors(true); ini_set('max_execution_time', 0); ini_set('max_input_time', 0); set_time_limit(0); $maxChildWorkers = 10; $html = new DOMDocument(); $html->loadHtmlFile('http://xxxx'); $xPath = new DOMXPath($html); $domQuery = '//div[@id=productDetail]/a'; $domReturn = $xPath->query($domQuery); $hrefsArray[] = $domReturn->getAttribute('href'); function doDomStuff($singleHref) { // Do stuff here with each product } // To figure out: Split href array into $maxChilderWorks # of workArray1, workArray2 ... workArray10. $pids = array(); foreach ($workArray(1,2,3 ... 10) as $singleHref) { $pid = pcntl_fork(); if ($pid == -1) { die("Couldn't fork, error!"); } elseif ($pid > 0) { // We are the parent $pids[] = $pid; } else { // We are the child $childPid = posix_getpid(); doDomStuff($singleHref); exit(0); } } foreach ($pids as $pid) { pcntl_waitpid($pid, $status); } // Clear the libxml buffer so it doesn't fill up libxml_clear_errors(); But what I can't figure out is how to build my hrefsArray[] in the master/parent process only and feed it off to the child process. Currently everything I've tried causes loops in the child processes. I.e. my hrefsArray gets built in the master, and in each subsequent child process. I am sure I am going about this all totally wrong, so would greatly appreciate just general nudge in the right direction.

• Link List Implementation Help - Visual C++

  - by Greenhouse Gases

  Hi there I'm trying to implement a link list which stores the city name (though you will see this commented out as I need to resolve the issue of not being able to use string and needing to use a primitive data type instead during the declaration), longitude, latitude and of course a pointer to the next node in the chain. I am new to the Visual C++ environment and my brain is somewhat scrambled after coding for several straight hours today so I wondered if anyone could help resolve the 2 errors I am getting (ignore the #include syntax as I had to change them to avoid the browser interpreting html!): 1U08221.obj : error LNK2028: unresolved token (0A000298) "public: __thiscall Locations::Locations(void)" (??0Locations@@$$FQAE@XZ) referenced in function "int __clrcall main(cli::array^)" (?main@@$$HYMHP$01AP$AAVString@System@@@Z) 1U08221.obj : error LNK2019: unresolved external symbol "public: __thiscall Locations::Locations(void)" (??0Locations@@$$FQAE@XZ) referenced in function "int __clrcall main(cli::array^)" (?main@@$$HYMHP$01AP$AAVString@System@@@Z) The code for my header file is here: include string struct locationNode { //char[10] nodeCityName; double nodeLati; double nodeLongi; locationNode* Next; }; class Locations { private: int size; public: Locations(); // constructor for the class locationNode* Head; int Add(locationNode* Item); }; and here is the code for the file containing the main method: // U08221.cpp : main project file. include "stdafx.h" include "Locations.h" include iostream include string using namespace std; int n = 0; int x; string cityNameInput; bool acceptedInput = false; int Locations::Add(locationNode *NewItem) { locationNode *Sample = new locationNode; Sample = NewItem; Sample-Next = Head; Head = Sample; return size++; } void CorrectCase(string name) // Correct upper and lower case letters of input { x = name.size(); int firstLetVal = name[0], letVal; n = 1; // variable for name index from second letter onwards if((name[0] 90) && (name[0] < 123)) // First letter is lower case { firstLetVal = firstLetVal - 32; // Capitalise first letter name[0] = firstLetVal; } while(n <= x - 1) { if((name[n] = 65) && (name[n] <= 90)) { letVal = name[n] + 32; name[n] = letVal; } n++; } cityNameInput = name; } void nameValidation(string name) { n = 0; // start from first letter x = name.size(); while(!acceptedInput) { if((name[n] = 65) && (name[n] <= 122)) // is in the range of letters { while(n <= x - 1) { while((name[n] =91) && (name[n] <=97)) // ERROR!! { cout << "Please enter a valid city name" << endl; cin name; } n++; } } else { cout << "Please enter a valid city name" << endl; cin name; } if(n <= x - 1) { acceptedInput = true; } } cityNameInput = name; } int main(array ^args) { cout << "Enter a city name" << endl; cin cityNameInput; nameValidation(cityNameInput); // check is made up of valid characters CorrectCase(cityNameInput); // corrects name to standard format of capitalised first letter, and lower case subsequent letters cout << cityNameInput; cin cityNameInput; Locations::Locations(); Locations *Parts = new Locations(); locationNode *Part; Part = new locationNode; //Part-nodeCityName = "London"; Part-nodeLati = 87; Part-nodeLongi = 80; Parts-Add(Part); } I am familiar with the concepts but somewhat inexperienced with OOP so am making some silly errors that you can never find when you've stared at something too long. Any help you can offer will be appreciated! Thanks

• Patching this Code to apply dynamic (iPhone) background position

  - by Brian

  I posted a question previously that got off topic, I'm reposting with better code that I have VERIFIED is compatible with iPhone (it works with mine anyway!) I just want to apply background-position coordinates to the body element and call the script conditionally for iPhone, iPod, & iPad. Here's my conditional call for those devices: var deviceAgent = navigator.userAgent.toLowerCase(); var agentID = deviceAgent.match(/(iphone|ipod|ipad)/); if (agentID) { // do something } else { //do this } Now, I've found this excellent script that sets the "top: x" dynamically on the basis of scroll position. Everyone has told me (and ALL of the tutorials and Google search results as well) that it's impossible to set scroll position dynamically for iPhone because of the viewport issue. HOWEVER, they are wrong because if you scroll to the bottom of the page and view this javascript demo on iPhone, you can scroll and the <div style="background-position: fixed; top: x (variable)"></div> div DOES stay centered on iPhone. I really hope this question helps alot of people, I thought it was impossible, but it's NOT... I just need help stitching it together! The original code (you can test it on iPhone yourself) is here: http://stevenbenner.com/2010/04/calculate-page-size-and-view-port-position-in-javascript/ So I just need help getting the following code to apply the dynamic "background-position: 0 x" to the BODY tag where x is centered and relative to the viewport position. Also, needs to be nested inside the above code that is conditional for iPhone and similar devices. // Page Size and View Port Dimension Tools // http://stevenbenner.com/2010/04/calculate-page-size-and-view-port-position-in-javascript/ if (!sb_windowTools) { var sb_windowTools = new Object(); }; sb_windowTools = { scrollBarPadding: 17, // padding to assume for scroll bars // EXAMPLE METHODS // center an element in the viewport centerElementOnScreen: function(element) { var pageDimensions = this.updateDimensions(); element.style.top = ((this.pageDimensions.verticalOffset() + this.pageDimensions.windowHeight() / 2) - (this.scrollBarPadding + element.offsetHeight / 2)) + 'px'; element.style.left = ((this.pageDimensions.windowWidth() / 2) - (this.scrollBarPadding + element.offsetWidth / 2)) + 'px'; element.style.position = 'absolute'; }, // INFORMATION GETTERS // load the page size, view port position and vertical scroll offset updateDimensions: function() { this.updatePageSize(); this.updateWindowSize(); this.updateScrollOffset(); }, // load page size information updatePageSize: function() { // document dimensions var viewportWidth, viewportHeight; if (window.innerHeight && window.scrollMaxY) { viewportWidth = document.body.scrollWidth; viewportHeight = window.innerHeight + window.scrollMaxY; } else if (document.body.scrollHeight > document.body.offsetHeight) { // all but explorer mac viewportWidth = document.body.scrollWidth; viewportHeight = document.body.scrollHeight; } else { // explorer mac...would also work in explorer 6 strict, mozilla and safari viewportWidth = document.body.offsetWidth; viewportHeight = document.body.offsetHeight; }; this.pageSize = { viewportWidth: viewportWidth, viewportHeight: viewportHeight }; }, // load window size information updateWindowSize: function() { // view port dimensions var windowWidth, windowHeight; if (self.innerHeight) { // all except explorer windowWidth = self.innerWidth; windowHeight = self.innerHeight; } else if (document.documentElement && document.documentElement.clientHeight) { // explorer 6 strict mode windowWidth = document.documentElement.clientWidth; windowHeight = document.documentElement.clientHeight; } else if (document.body) { // other explorers windowWidth = document.body.clientWidth; windowHeight = document.body.clientHeight; }; this.windowSize = { windowWidth: windowWidth, windowHeight: windowHeight }; }, // load scroll offset information updateScrollOffset: function() { // viewport vertical scroll offset var horizontalOffset, verticalOffset; if (self.pageYOffset) { horizontalOffset = self.pageXOffset; verticalOffset = self.pageYOffset; } else if (document.documentElement && document.documentElement.scrollTop) { // Explorer 6 Strict horizontalOffset = document.documentElement.scrollLeft; verticalOffset = document.documentElement.scrollTop; } else if (document.body) { // all other Explorers horizontalOffset = document.body.scrollLeft; verticalOffset = document.body.scrollTop; }; this.scrollOffset = { horizontalOffset: horizontalOffset, verticalOffset: verticalOffset }; }, // INFORMATION CONTAINERS // raw data containers pageSize: {}, windowSize: {}, scrollOffset: {}, // combined dimensions object with bounding logic pageDimensions: { pageWidth: function() { return sb_windowTools.pageSize.viewportWidth > sb_windowTools.windowSize.windowWidth ? sb_windowTools.pageSize.viewportWidth : sb_windowTools.windowSize.windowWidth; }, pageHeight: function() { return sb_windowTools.pageSize.viewportHeight > sb_windowTools.windowSize.windowHeight ? sb_windowTools.pageSize.viewportHeight : sb_windowTools.windowSize.windowHeight; }, windowWidth: function() { return sb_windowTools.windowSize.windowWidth; }, windowHeight: function() { return sb_windowTools.windowSize.windowHeight; }, horizontalOffset: function() { return sb_windowTools.scrollOffset.horizontalOffset; }, verticalOffset: function() { return sb_windowTools.scrollOffset.verticalOffset; } } };

As I'm writing, one explanation that pops into my head is that the API pre-dates Java 1.5; and although the signatures would be source-level compatible, the binary interface would differ. Isn't it?

• Only show items owned by the currently logged in user in category list view

  - by jalbasri

  I'd like to be able to provide a "Category List" view that only shows Articles that the currently logged in user owns. Is there somewhere I can edit the query used to populate the Category List view or an extension that provides this functionality. Thank you for any help you can provide. -J. Thank you for your answer. I've written the plugin. Instead of passing in an array of Articles the onContentBeforeDisplay function is called for every article and an ArrayObject of the single article gets passed in. I've been able to identify the articles I want not to be displayed but still cannot get them not to display. The $params variable has values such as "list_show_xxx" but I can't seem to change or access them. here is a var_dump($params): object(Joomla\Registry\Registry)#190 (1) { ["data":protected]=> object(stdClass)#250 (83) { ["article_layout"]=> string(9) "_:default" ["show_title"]=> string(1) "1" ["link_titles"]=> string(1) "1" ["show_intro"]=> string(1) "1" ["info_block_position"]=> string(1) "1" ["show_category"]=> string(1) "1" ["link_category"]=> string(1) "1" ["show_parent_category"]=> string(1) "0" ["link_parent_category"]=> string(1) "0" ["show_author"]=> string(1) "1" ["link_author"]=> string(1) "0" ["show_create_date"]=> string(1) "0" ["show_modify_date"]=> string(1) "0" ["show_publish_date"]=> string(1) "1" ["show_item_navigation"]=> string(1) "1" ["show_vote"]=> string(1) "0" ["show_readmore"]=> string(1) "1" ["show_readmore_title"]=> string(1) "1" ["readmore_limit"]=> string(3) "100" ["show_tags"]=> string(1) "1" ["show_icons"]=> string(1) "1" ["show_print_icon"]=> string(1) "1" ["show_email_icon"]=> string(1) "1" ["show_hits"]=> string(1) "1" ["show_noauth"]=> string(1) "0" ["urls_position"]=> string(1) "0" ["show_publishing_options"]=> string(1) "0" ["show_article_options"]=> string(1) "0" ["save_history"]=> string(1) "1" ["history_limit"]=> int(10) ["show_urls_images_frontend"]=> string(1) "0" ["show_urls_images_backend"]=> string(1) "1" ["targeta"]=> int(0) ["targetb"]=> int(0) ["targetc"]=> int(0) ["float_intro"]=> string(4) "left" ["float_fulltext"]=> string(4) "left" ["category_layout"]=> string(9) "_:default" ["show_category_heading_title_text"]=> string(1) "1" ["show_category_title"]=> string(1) "0" ["show_description"]=> string(1) "0" ["show_description_image"]=> string(1) "0" ["maxLevel"]=> string(1) "1" ["show_empty_categories"]=> string(1) "0" ["show_no_articles"]=> string(1) "1" ["show_subcat_desc"]=> string(1) "1" ["show_cat_num_articles"]=> string(1) "0" ["show_base_description"]=> string(1) "1" ["maxLevelcat"]=> string(2) "-1" ["show_empty_categories_cat"]=> string(1) "0" ["show_subcat_desc_cat"]=> string(1) "1" ["show_cat_num_articles_cat"]=> string(1) "1" ["num_leading_articles"]=> string(1) "1" ["num_intro_articles"]=> string(1) "4" ["num_columns"]=> string(1) "1" ["num_links"]=> string(1) "4" ["multi_column_order"]=> string(1) "0" ["show_subcategory_content"]=> string(1) "0" ["show_pagination_limit"]=> string(1) "1" ["filter_field"]=> string(5) "title" ["show_headings"]=> string(1) "1" ["list_show_date"]=> string(1) "0" ["date_format"]=> string(0) "" ["list_show_hits"]=> string(1) "1" ["list_show_author"]=> string(1) "1" ["orderby_pri"]=> string(5) "order" ["orderby_sec"]=> string(5) "rdate" ["order_date"]=> string(9) "published" ["show_pagination"]=> string(1) "2" ["show_pagination_results"]=> string(1) "1" ["show_feed_link"]=> string(1) "1" ["feed_summary"]=> string(1) "0" ["feed_show_readmore"]=> string(1) "0" ["display_num"]=> string(2) "10" ["menu_text"]=> int(1) ["show_page_heading"]=> int(0) ["secure"]=> int(0) ["page_title"]=> string(16) "Non-K2 News List" ["page_description"]=> string(33) "Bahrain Business Incubator Centre" ["page_rights"]=> NULL ["robots"]=> NULL ["access-edit"]=> bool(true) ["access-view"]=> bool(true) } } I've tried $params-data-list_show_author = "0" but then the page doesn't load, problem is accessing and changing the variables in $param. So the last step is to figure out how not to show the article. Any ideas?

• Designing an API with compile-time option to remove first parameter to most functions and use a glob

  - by tomlogic

  I'm trying to design a portable API in ANSI C89/ISO C90 to access a wireless networking device on a serial interface. The library will have multiple network layers, and various versions need to run on embedded devices as small as an 8-bit micro with 32K of code and 2K of data, on up to embedded devices with a megabyte or more of code and data. In most cases, the target processor will have a single network interface and I'll want to use a single global structure with all state information for that device. I don't want to pass a pointer to that structure through the network layers. In a few cases (e.g., device with more resources that needs to live on two networks) I will interface to multiple devices, each with their own global state, and will need to pass a pointer to that state (or an index to a state array) through the layers. I came up with two possible solutions, but neither one is particularly pretty. Keep in mind that the full driver will potentially be 20,000 lines or more, cover multiple files, and contain hundreds of functions. The first solution requires a macro that discards the first parameter for every function that needs to access the global state: // network.h typedef struct dev_t { int var; long othervar; char name[20]; } dev_t; #ifdef IF_MULTI #define foo_function( x, a, b, c) _foo_function( x, a, b, c) #define bar_function( x) _bar_function( x) #else extern dev_t DEV; #define IFACE (&DEV) #define foo_function( x, a, b, c) _foo_function( a, b, c) #define bar_function( x) _bar_function( ) #endif int bar_function( dev_t *IFACE); int foo_function( dev_t *IFACE, int a, long b, char *c); // network.c #ifndef IF_MULTI dev_t DEV; #endif int bar_function( dev_t *IFACE) { memset( IFACE, 0, sizeof *IFACE); return 0; } int foo_function( dev_t *IFACE, int a, long b, char *c) { bar_function( IFACE); IFACE->var = a; IFACE->othervar = b; strcpy( IFACE->name, c); return 0; } The second solution defines macros to use in the function declarations: // network.h typedef struct dev_t { int var; long othervar; char name[20]; } dev_t; #ifdef IF_MULTI #define DEV_PARAM_ONLY dev_t *IFACE #define DEV_PARAM DEV_PARAM_ONLY, #else extern dev_t DEV; #define IFACE (&DEV) #define DEV_PARAM_ONLY void #define DEV_PARAM #endif int bar_function( DEV_PARAM_ONLY); // I don't like the missing comma between DEV_PARAM and arg2... int foo_function( DEV_PARAM int a, long b, char *c); // network.c #ifndef IF_MULTI dev_t DEV; #endif int bar_function( DEV_PARAM_ONLY) { memset( IFACE, 0, sizeof *IFACE); return 0; } int foo_function( DEV_PARAM int a, long b, char *c) { bar_function( IFACE); IFACE->var = a; IFACE->othervar = b; strcpy( IFACE->name, c); return 0; } The C code to access either method remains the same: // multi.c - example of multiple interfaces #define IF_MULTI #include "network.h" dev_t if0, if1; int main() { foo_function( &if0, -1, 3.1415926, "public"); foo_function( &if1, 42, 3.1415926, "private"); return 0; } // single.c - example of a single interface #include "network.h" int main() { foo_function( 11, 1.0, "network"); return 0; } Is there a cleaner method that I haven't figured out? I lean toward the second since it should be easier to maintain, and it's clearer that there's some macro magic in the parameters to the function. Also, the first method requires prefixing the function names with "_" when I want to use them as function pointers. I really do want to remove the parameter in the "single interface" case to eliminate unnecessary code to push the parameter onto the stack, and to allow the function to access the first "real" parameter in a register instead of loading it from the stack. And, if at all possible, I don't want to have to maintain two separate codebases. Thoughts? Ideas? Examples of something similar in existing code? (Note that using C++ isn't an option, since some of the planned targets don't have a C++ compiler available.)

• Having trouble comparing a range of dates entered in a form with records in a mySQL database

  - by Andrew Fox

  I have a table called schedule and a column called Date where the column type is date. In that column I have a range of dates, which is currently from 2012-11-01 to 2012-11-30. I have a small form where the user can enter a range of dates (input names from and to) and I want to be able to compare the range of dates with the dates currently in the database. This is what I have: //////////////////////////////////////////////////////// //////First set the date range that we want to use////// //////////////////////////////////////////////////////// if(isset($_POST['from']) && ($_POST['from'] != NULL)) { $startDate = $_POST['from']; } else { //Default date is Today $startDate = date("Y-m-d"); } if(isset($_POST['to']) && ($_POST['to'] != NULL)) { $endDate = $_POST['to']; } else { //Default day is one month from today $endDate = date("Y-m-d", strtotime("+1 month")); } ////////////////////////////////////////////////////////////////////////////////////// //////Next calculate the total amount of days selected above to use as a limiter////// ////////////////////////////////////////////////////////////////////////////////////// $dayStart = strtotime($startDate); $dayEnd = strtotime($endDate); $total_days = abs($dayEnd - $dayStart) / 86400 +1; echo "Start Date: " . $startDate . "<br>End Date: " . $endDate . "<br>"; echo "Day Start: " . $dayStart . "<br>Day End: " . $dayEnd . "<br>"; echo "Total Days: " . $total_days . "<br>"; //////////////////////////////////////////////////////////////////////////////////// //////Then we're going to see if the dates selected are in the schedule table////// //////////////////////////////////////////////////////////////////////////////////// //Select all of the dates currently in the schedule table between the range selected. $sql = ("SELECT Date FROM schedule WHERE Date BETWEEN '$startDate' AND '$endDate' LIMIT $total_days"); //Run a check on the query to make sure it worked. If it failed then print the error. if(!$result_date_query = $mysqli->query($sql)) { die('There was an error getting the dates from the schedule table [' . $mysqli->error . ']'); } //Set the dates to an array for future use. // $current_dates = $result_date_query->fetch_assoc(); //Loop through the results while a result is being returned. while($row = $result_date_query->fetch_assoc()) { echo "Row: " . $row['Date'] . "<br>"; echo "Start day: " . date('Y-m-d', $dayStart) . "<br>"; //Set this loop to add 1 day to the Start Date until it reaches the End Date for($i = $dayStart; $i <= $dayEnd; $i = strtotime('+1 day', $i)) { $date = date('Y-m-d',$i); echo "Loop Start day: " . date('Y-m-d', $dayStart) . "<br>"; //Run a check to see if any of the dates selected are in the schedule table. if($row['Date'] != $date) { echo "Current Date: " . $row['Date'] . "<br>"; echo "Date: " . $date . "<br>"; echo "It appears as though you've selected some dates that are not in the schedule database.<br>Please correct the issue and try again."; return; } } } //Free the result so something else can use it. $result_date_query->free(); As you can see I've added in some echo statements so I can see what is being produced. From what I can see it looks like my $row['Date'] is not incrementing and staying at the same date. I originally had it set to a variable (currently commented out) but I thought that could be causing problems. I have created the table with dates ranging from 2012-11-01 to 2012-11-15 for testing and entered all of this php code onto phpfiddle.org but I can't get the username provided to connect. Here is the link: PHP Fiddle I'll be reading through the documentation to try and figure out the user connection problem in the meantime, I would really appreciate any direction or advice you can give me.

Thanks Here is the PHP file I include: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html dir="ltr" xmlns="http://www.w3.org/1999/xhtml"> <head> <meta content="en-us" http-equiv="Content-Language" /> <title>Accueil</title> <meta content="text/html; charset=utf-8" http-equiv="Content-Type" /> <meta content="Changement créativité rêve buts être centré Plénitude personnel Développement transformation Modification nouveauté avancement bien-être Nouvelle vision ressentis L’énergie positive satisfaction l’acceptation Pardon" name="keywords" /> <link href="masterstyles.css" rel="stylesheet" type="text/css" /> <link href="menustyles.css" rel="stylesheet" type="text/css" /> <link href="menudropdown.css" rel="stylesheet" type="text/css" /> <td class="tbsyles" >&nbsp; <h3 class="bigorange"> ACTIVITÉS À VENIR…</h3> <p class="horizblue"> </p> <p class="bigblack"> <br /> Inscrivez-vous à nos conférences et formations <br /> <br /> </p> <h4 class="orange"> Example of some text that could be here<br /> </h4> <p class="horizblue"> &nbsp;</p> <h3 class="bigorange"> <br /> ABONNEZ-VOUS… </h3> <p class="nopadding"> À notre liste d’envoi </p> <form method="post" action="<?php echo $PHP_SELF;?>"> <?PHP function process_info(){ if(isset($_POST['email'])) { $email=$_POST["email"]; $email=strtolower($email); $action = "subc"; // check if email exists // check whether email is correct (basic checking) $test1=strpos($email, "@"); //value must be >1 $test2=strpos(substr($email,strpos($email,"@")), "."); //value must be >1 $test3=strlen($email); //value must be >6 $test4=substr_count ($email,"@"); //value must be 1 if ($test1<2 or $test2<2 or $test3<7 or $test4!=1) { print "<h6>Il a une erreur avec vôtre email</h6>"; print "<h6>Aucune informations ont été envoyer</h6>"; } else { print "<h5>vôtre address est enregistrer, Merci </h5>"; //If they wanted to subsribe, do it... $file = "emaillist-666XXX.txt"; // lets try to get the content of the file if (file_exists($file)){ // If the file is already in the server, its content is pasted to variable $file_content $file_content=file_get_contents($file); } else{ // If the file does not exists, lets try to create it // In case file can not be created (probably due to problems with directory permissions), // the users is informed (the first user will be the webmaster, who must solve the problem). $cf = fopen($file, "w") or die(""); fclose($cf); } // IF REQUEST HAS BEEN TO SUBSCRIBE FROM MAILING LIST, ADD EMAIL TO THE FILE if ($action=="subc"){ // check whether the email is already registered if(strpos($file_content,"<$email>")>0){die("");} // write the email to the list (append it to the file) $cf = fopen($file, "a"); fputs($cf, "\n$email"); // new email is written to the file in a new line fclose($cf); } } } } process_info(); ?> &nbsp;<p class="nopadding">Votre Courriel</p> <input name="email" type="text" class="style3" /> <input name="Submit" type="submit" value="OK" /></form> <p class="horizblue"></p> <h3 class="bigorange"> <br /> OUTILS GRATUIT… </h3> <p class="nopadding">Amusez-vous avec des outils intéressants</p> </td>

• Simple prime number program - Weird issue with threads C#

  - by Para

  Hi! This is my code: using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading; namespace FirePrime { class Program { static bool[] ThreadsFinished; static bool[] nums; static bool AllThreadsFinished() { bool allThreadsFinished = false; foreach (var threadFinished in ThreadsFinished) { allThreadsFinished &= threadFinished; } return allThreadsFinished; } static bool isPrime(int n) { if (n < 2) { return false; } if (n == 2) { return true; } if (n % 2 == 0) { return false; } int d = 3; while (d * d <= n) { if (n % d == 0) { return false; } d += 2; } return true; } static void MarkPrimes(int startNumber,int stopNumber,int ThreadNr) { for (int j = startNumber; j < stopNumber; j++) nums[j] = isPrime(j); lock (typeof(Program)) { ThreadsFinished[ThreadNr] = true; } } static void Main(string[] args) { int nrNums = 100; int nrThreads = 10; //var threadStartNums = new List<int>(); ThreadsFinished = new bool[nrThreads]; nums = new bool[nrNums]; //var nums = new List<bool>(); nums[0] = false; nums[1] = false; for(int i=2;i<nrNums;i++) nums[i] = true; int interval = (int)(nrNums / nrThreads); //threadStartNums.Add(2); //int aux = firstStartNum; //int i = 2; //while (aux < interval) //{ // aux = interval*i; // i=i+1; // threadStartNums.Add(aux); //} int startNum = 0; for (int i = 0; i < nrThreads; i++) { var _thread = new System.Threading.Thread(() => MarkPrimes(startNum, Math.Min(startNum + interval, nrNums), i)); startNum = startNum + interval; //set the thread to run in the background _thread.IsBackground = true; //start our thread _thread.Start(); } while (!AllThreadsFinished()) { Thread.Sleep(1); } for (int i = 0; i < nrNums; i++) if(nums[i]) Console.WriteLine(i); } } } This should be a pretty simple program that is supposed to find and output the first nrNums prime numbers using nrThreads threads working in parallel. So, I just split nrNums into nrThreads equal chunks (well, the last one won't be equal; if nrThreads doesn't divide by nrNums, it will also contain the remainder, of course). I start nrThreads threads. They all test each number in their respective chunk and see if it is prime or not; they mark everything out in a bool array that keeps a tab on all the primes. The threads all turn a specific element in another boolean array ThreadsFinished to true when they finish. Now the weird part begins: The threads never all end. If I debug, I find that ThreadNr is not what I assign to it in the loop but another value. I guess this is normal since the threads execute afterwards and the counter (the variable i) is already increased by then but I cannot understand how to make the code be right. Can anyone help? Thank you in advance. P.S.: I know the algorithm is not very efficient; I am aiming at a solution using the sieve of Eratosthenes also with x given threads. But for now I can't even get this one to work and I haven't found any examples of any implementations of that algorithm anywhere in a language that I can understand.

• Assigning two strings together getting Access Read Violation

  - by Jay Bell

  I am trying to pass a string to a class mutator and set the private member to that string here is the code that is sending the string void parseTradePairs(Exchange::Currency *curr, std::string *response, int begin, int exit) { int start; int end; string temp; string dataResponse; CURL *tempCurl; initializeCurl(tempCurl); int location = response->find("marketid", begin); if(location <= exit) { start = location + 11; begin = response->find("label", start); end = begin - start - 3; findStrings(start, end, temp, response); getMarketInfo(tempCurl, temp, dataResponse); curr->_coin->setExch(temp); // here is the line of code that is sending the string dataResponse >> *(curr->_coin); curr->_next = new Exchange::Currency(curr, curr->_position + 1); parseTradePairs(curr->_next, response, begin, exit); } } and here is the mutator within the coin class that is receiving the string and assigning it to _exch void Coin::setExch(string exch) { _exch = exch; } I have stepped through it and made sure that exch has the string in it. "105" but soon as it hits _exch = exch; I get the reading violation. I tried passing as pointer as well. I do not believe it should go out of scope. and the string variable in the class is initialized to zero in the default constructor but again that should matter unless I am trying to read from it instead of writing to it. /* defualt constructor */ Coin::Coin() { _id = ""; _label = ""; _code= ""; _name = ""; _marketCoin = ""; _volume = 0; _last = 0; _exch = ""; } Exchange::Exchange(std::string str) { _exch = str; _currencies = new Currency; std::string pair; std::string response; CURL *curl; initializeCurl(curl); getTradePairs(curl, response); int exit = response.find_last_of("marketid"); parseTradePairs(_currencies, &response, 0, exit); } int main(void) { CURL *curl; string str; string id; Coin coin1; initializeCurl(curl); Exchange ex("cryptsy"); curl_easy_cleanup(curl); system("pause"); return 0; } class Exchange { public: typedef struct Currency { Currency(Coin *coin, Currency *next, Currency *prev, int position) : _coin(coin), _next(next), _prev(prev), _position(position) {} Currency(Currency *prev, int position) : _prev(prev), _position(position), _next(NULL), _coin(&Coin()){} Currency() : _next(NULL), _prev(NULL), _position(0) {} Coin *_coin; Currency *_next; Currency *_prev; int _position; }; /* constructor and destructor */ Exchange(); Exchange(std::string str); ~Exchange(); /* Assignment operator */ Exchange& operator =(const Exchange& copyExchange); /* Parse Cryptsy Pairs */ friend void parseTradePairs(Currency *curr, std::string *response, int begin, int exit); private: std::string _exch; Currency *_currencies; }; here is what i changed it to to fix it. typedef struct Currency { Currency(Coin *coin, Currency *next, Currency *prev, int position) : _coin(coin), _next(next), _prev(prev), _position(position) {} Currency(Currency *prev, int position) : _prev(prev), _position(position), _next(NULL), _coin(&Coin()){} Currency() { _next = NULL; _prev = NULL; _position = 0; _coin = new Coin(); } Coin *_coin; Currency *_next; Currency *_prev; int _position; };

• OpenGL texture shifted somewhat to the left when applied to a quad

  - by user308226

  I'm a bit new to OpenGL and I've been having a problem with using textures. The texture seems to load fine, but when I run the program, the texture displays shifted a couple pixels to the left, with the section cut off by the shift appearing on the right side. I don't know if the problem here is in the my TGA loader or if it's the way I'm applying the texture to the quad. Here is the loader: #include "texture.h" #include <iostream> GLubyte uncompressedheader[12] = {0,0, 2,0,0,0,0,0,0,0,0,0}; GLubyte compressedheader[12] = {0,0,10,0,0,0,0,0,0,0,0,0}; TGA::TGA() { } //Private loading function called by LoadTGA. Loads uncompressed TGA files //Returns: TRUE on success, FALSE on failure bool TGA::LoadCompressedTGA(char *filename,ifstream &texturestream) { return false; } bool TGA::LoadUncompressedTGA(char *filename,ifstream &texturestream) { cout << "G position status:" << texturestream.tellg() << endl; texturestream.read((char*)header, sizeof(header)); //read 6 bytes into the file to get the tga header width = (GLuint)header[1] * 256 + (GLuint)header[0]; //read and calculate width and save height = (GLuint)header[3] * 256 + (GLuint)header[2]; //read and calculate height and save bpp = (GLuint)header[4]; //read bpp and save cout << bpp << endl; if((width <= 0) || (height <= 0) || ((bpp != 24) && (bpp !=32))) //check to make sure the height, width, and bpp are valid { return false; } if(bpp == 24) { type = GL_RGB; } else { type = GL_RGBA; } imagesize = ((bpp/8) * width * height); //determine size in bytes of the image cout << imagesize << endl; imagedata = new GLubyte[imagesize]; //allocate memory for our imagedata variable texturestream.read((char*)imagedata,imagesize); //read according the the size of the image and save into imagedata for(GLuint cswap = 0; cswap < (GLuint)imagesize; cswap += (bpp/8)) //loop through and reverse the tga's BGR format to RGB { imagedata[cswap] ^= imagedata[cswap+2] ^= //1st Byte XOR 3rd Byte XOR 1st Byte XOR 3rd Byte imagedata[cswap] ^= imagedata[cswap+2]; } texturestream.close(); //close ifstream because we're done with it cout << "image loaded" << endl; glGenTextures(1, &texID); // Generate OpenGL texture IDs glBindTexture(GL_TEXTURE_2D, texID); // Bind Our Texture glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); // Linear Filtered glTexParameterf(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); glTexImage2D(GL_TEXTURE_2D, 0, type, width, height, 0, type, GL_UNSIGNED_BYTE, imagedata); delete imagedata; return true; } //Public loading function for TGA images. Opens TGA file and determines //its type, if any, then loads it and calls the appropriate function. //Returns: TRUE on success, FALSE on failure bool TGA::loadTGA(char *filename) { cout << width << endl; ifstream texturestream; texturestream.open(filename,ios::binary); texturestream.read((char*)header,sizeof(header)); //read 6 bytes into the file, its the header. //if it matches the uncompressed header's first 6 bytes, load it as uncompressed LoadUncompressedTGA(filename,texturestream); return true; } GLubyte* TGA::getImageData() { return imagedata; } GLuint& TGA::getTexID() { return texID; } And here's the quad: void Square::show() { glEnable(GL_TEXTURE_2D); glBindTexture(GL_TEXTURE_2D, texture.texID); //Move to offset glTranslatef( x, y, 0 ); //Start quad glBegin( GL_QUADS ); //Set color to white glColor4f( 1.0, 1.0, 1.0, 1.0 ); //Draw square glTexCoord2f(0.0f, 0.0f); glVertex3f( 0, 0, 0 ); glTexCoord2f(1.0f, 0.0f); glVertex3f( SQUARE_WIDTH, 0, 0 ); glTexCoord2f(1.0f, 1.0f); glVertex3f( SQUARE_WIDTH, SQUARE_HEIGHT, 0 ); glTexCoord2f(0.0f, 1.0f); glVertex3f( 0, SQUARE_HEIGHT, 0 ); //End quad glEnd(); //Reset glLoadIdentity(); }

• Unwanted character being added to string in C

  - by Church

  I have a program that gives you shipping addresses from an input file. However at the beginning of one of the strings, order.add_one, a number is being added to the beginning of the string, that number is equivalent to the variable "choice" every time. Why is it doing this? #include <stdio.h> #include <math.h> #include <string.h> //structure typedef struct {char cust_name[25]; char cust_id[3]; char add_one[30]; char add_two[30]; char bike; char risky; int number_ordered; char cust_information[500]; }ORDER; ORDER order; int main(void){ fflush(stdin); system ( "clear" ); //initialize variables float price; float m = 359.95; float s = 279.95; //while loop, runs until user declares they no longer wish to input orders while (1==1){ printf("Options: \nEnter Customer information manually : 1 \nSearch Customer by ID(input.txt reader) : 2 \n"); int option = 0; scanf(" %d", &option); if (option == 1){ //Print and scan statements printf("Enter Customer Information\n"); printf("Customer Name: "); scanf(" %[^\n]s", &order.cust_name); printf("\nEnter Address Line One: "); scanf(" %[^\n]s", &order.add_one); printf("\nEnter Addres Line Two: "); scanf(" %[^\n]s", &order.add_two); printf("\nHow Many Bicycles Are Ordered: "); scanf(" %d", &order.number_ordered); printf("\nWhat Type Of Bike Is Ordered\n M Mountain Bike \n S Street Bike"); printf("\nChoose One (M or S): "); scanf(" %c", &order.bike); printf("\nIs The Customer Risky (Y/N): "); scanf(" %c", &order.risky); system ( "clear" ); } if (option == 2){ FILE *fpt; fpt = fopen("input.txt", "r"); if (fpt==NULL){ printf("Text file did not open\n"); return 1; } printf("Enter Customer ID: "); scanf("%s", &order.cust_id); char choice; choice = order.cust_id[0]; char x[3]; int w, u, y, z; char a[10], b[10], c[10], d[10], e[20], f[10], g[10], i[1], j[1]; int h; printf("%s value of c", c); if (choice >='1'){ while ((w = fgetc(fpt)) != '\n' ){ } } if (choice >='2'){ while ((u = fgetc(fpt)) != '\n' ){ } } if (choice >='3'){ while ((y = fgetc(fpt)) != '\n' ){ } } if (choice >= '4'){ while ((z = fgetc(fpt)) != '\n' ){ } } printf("\n"); fscanf(fpt, "%s", x); fscanf(fpt, "%s", a); printf("%s", a); strcat(order.cust_name, a); fscanf(fpt, " %s", b); printf(" %s", b); strcat(order.cust_name, " "); strcat(order.cust_name, b); fscanf(fpt, "%s", c); printf(" %s", c); strcat(order.add_one, "\0"); strcat(order.add_one, c); fscanf(fpt, "%s", d); printf(" %s", d); strcat(order.add_one, " "); strcat(order.add_one, d); fscanf(fpt, "%s", e); printf(" %s", e); strcat(order.add_two, e); fscanf(fpt, "%s", f); printf(" %s", f); strcat(order.add_two, " "); strcat(order.add_two, f); fscanf(fpt, "%s", g); printf(" %s", g); strcat(order.add_two, " "); strcat(order.add_two, g); strcat(order.add_two, "\0"); fscanf(fpt, "%d", &h); printf(" %d", h); order.number_ordered = h; fscanf(fpt, "%s", i); printf(" %s", i); order.bike = i[0]; fscanf(fpt, "%s", j); printf(" %s", j); order.risky = j[0]; fclose(fpt); printf("%s %s %s %d %c %c", order.cust_name, order.add_one, order.add_two, order.number_ordered, order.bike, order.risky); }
