  - by user3251606

  Ok so i am working on a plugin for my server that will open and inventory and when closed it will pass items to this class... object of this class is to cycle through the inventory and use a cfg file to define items and prices and then grab that info in a for loop and add it all up... heres what i have thus far... public void sell(Player p, Inventory inv) { ListIterator<ItemStack> it = inv.iterator(); double total = 0; for (ItemStack is : inv) { is = it.next(); if (is.getType() != null) { String type = is.getType().toString(); //short dur = is.getDurability(); String check = ChestSell.plugin.getConfig().getString(type); p.sendMessage("Item Type: " + type); if (check != null) { int amou = is.getAmount(); double value = ChestSell.plugin.getConfig().getDouble(type + ".price"); double tv = amou * value; p.sendMessage("Items in chest: Type " + type + " Ammount: " + amou + " Value: $" + tv); } //TODO Add return Items } } p.sendMessage("You got paid $" + total + " for your items!"); inv.clear(); }

• RPGMakerVX - Changing item_max?

  - by rackemup420

  I've been working on a game for awhile and I am developing it with RPG Maker VX. I came to a point where I needed to... I guess for lack of better explanation... Limit the key items to just 1. So I started looking through my scripts and found (in Game_Party): #-------------------------------------------------------------------------- # * Get Maximum Number of Items Possessed #-------------------------------------------------------------------------- def max_item_number(item) return 99 end and added below it: #-------------------------------------------------------------------------- # * Get Maximum Number of Key Items Possessed #-------------------------------------------------------------------------- def max_key_item_number(item) return 1 end and right below that is: #-------------------------------------------------------------------------- # * Determine if Maximum Number of Items Are Possessed #-------------------------------------------------------------------------- def item_max?(item) item_number(item) >= max_item_number(item) end So I changed the last one too: #-------------------------------------------------------------------------- # * Determine if Maximum Number of Items Are Possessed #-------------------------------------------------------------------------- def item_max?(item) if key_item? == true item_number(item) >= max_key_item_number(item) end if key_item? == false item_number(item) >= max_item_number(item) end end Now this seemed to not affect anything (that I could tell). I tested it and its still the same as before I touched anything. I am new to developing games and relatively new to scripting for them. Is this approach even close to what I want to do? Any help is greatly apprecieated!

• jQuery Sortable .toArray with ASP.NET MVC ActionResult

  - by Stacey

  Third try at fixing this tonight - trying a different approach than before now. Given a jQuery Sortable List.. <ul id="sortable1" class="connectedSortable"> <li class="ui-state-default" id="item1">Item 1</li> <li class="ui-state-default" id="item2">Item 2</li> <li class="ui-state-default">Item 3</li> <li class="ui-state-default ">Item 4</li> <li class="ui-state-default">Item 5</li> </ul> <ul id="sortable2" class="connectedSortable"> </ul> And ASP.NET MVC ActionResult.. [AcceptVerbs(HttpVerbs.Post)] public ActionResult Insert( string[] items ) { return null; } Activated by JavaScript... $("#sortable1, #sortable2").sortable({ connectWith: '.connectedSortable', dropOnEmpty: true, receive: function () { var items = $(this).sortable('toArray'); alert(items); $.ajax({ url: '/Manage/Events/Insert', type: 'post', data: { 'items': items } }); } }).disableSelection(); The 'alert' DOES show the right items. It shows 'item1, item2' etc. But my ASP.NET MVC ActionResult gets nothing. The method DOES fire, but the 'items' parameter comes in null. Any ideas?

• Android addTextChangedListener onTextChanged not fired when Backspace is pressed?

  - by tsil

  I use addTextChangeListener to filter a list items. When the user enters a character on the editText, items are filtered based on user input. For example, if the user enters "stackoverflow", all items that contains "stackoverflow" are displayed. It works fine except that once the user press backspace to delete character(s), items are no longer filtered until he deletes all characters. For example, my items are: "stackoverflow 1", "stackoverflow 2", "stackoverflow 3", "stackoverflow 4". If user input is "stackoverflow", all items are displayed. If user input is "stackoverflow 1", only "stackoverflow 1" is displayed. Then user deletes the last 2 characters (1 and the space). User input is now "stackoverflow" but "stackoverflow 1" is still displayed and the other items are not displayed. This is my custom filter: private class ServiceFilter extends Filter { @Override protected FilterResults performFiltering(CharSequence constraint) { FilterResults results = new FilterResults(); if (constraint == null || constraint.length() == 0) { // No filter implemented we return all the list results.values = origServiceList; results.count = origServiceList.size(); } else { List<ServiceModel> nServiceList = new ArrayList<ServiceModel>(); for (ServiceModel s : serviceList) { if (s.getName().toLowerCase().contains(constraint.toString().toLowerCase())) { nServiceList.add(s); } } results.values = nServiceList; results.count = nServiceList.size(); } return results; } @Override protected void publishResults(CharSequence constraint, FilterResults results) { if (results.count == 0) { notifyDataSetInvalidated(); } else { serviceList = (List<ServiceModel>) results.values; notifyDataSetChanged(); } } } And how I handle text change event: inputSearch.addTextChangedListener(new TextWatcher() { @Override public void afterTextChanged(Editable arg0) { // TODO Auto-generated method stub } @Override public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) { // TODO Auto-generated method stub } @Override public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) { if (cs.length() >= 1) { mAdapter.getFilter().filter(cs); } else { mAdapter = new ServiceAdapter(MyActivity.this, R.layout.ussd_list_item, serviceList); listView.setAdapter(mAdapter); } } });

• How to set up Hierarchical Zend Rest Routes?

  - by Kenji Baheux

  With the Zend Framework, I am trying to build routes for a REST api on resources organized in the following pattern: http://example.org/users/ http://example.org/users/234 http://example.org/users/234/items http://example.org/users/234/items/34 How do I set up this with Zend_Rest_Route? Here is how I have setup the route for the users resource (users/:id) in my bootstrap.php file: $this->bootstrap('frontController'); $frontController = Zend_Controller_Front::getInstance(); $restRoute = new Zend_Rest_Route($frontController); $frontController->getRouter()->addRoute('default', $restRoute); [As far as I understand, this is a catch all route so users/324/items/34 would results in parameters set as id=324 and items=34 and everything would be mapped to the Users (front module) Model. From there I guess I could just test for the items parameter and retrieve the item #34 for user #324 on a get request.]<=== I just checked it and it doesn't seems to work like that: Acessing /users/234/items/43 and var_dump($this->_getAllParams()); in the get action of the rest controller results in the following output: array(4) { ["controller"]=> string(5) "users" ["action"]=> string(3) "get" [2]=> string(5) "items" ["module"]=> string(7) "default"] } Somehow both ids got lost... Anyone?

• How do I make a jQuery POST function open the new page?

  - by ciclistadan

  I know that a submit button in HTML can submit a form which opens the target page, but how do I cause a jQuery ajax call POST information to a new page and display the new page. I am submitting information that is gathered by clicking elements (which toggle a new class) and then all items with this new class are added to an array and POSTed to a new page. I can get it to POST the data but it seems to be working functioning in an ajax non-refreshing manner, not submitting the page and redirecting to the new page. how might I go about doing this? here's the script section: //onload function $(function() { //toggles items to mark them for purchase //add event handler for selecting items $(".line").click(function() { //get the lines item number var item = $(this).toggleClass("select").attr("name"); }); $('#process').click(function() { var items = []; //place selected numbers in a string $('.line.select').each(function(index){ items.push($(this).attr('name')); }); $.ajax({ type: 'POST', url: 'additem.php', data: 'items='+items, success: function(){ $('#menu').hide(function(){ $('#success').fadeIn(); }); } }); }); return false; }); any pointers would be great!! thanks

• Syncronization Exception

  - by Kurru

  Hi I have two threads, one thread processes a queue and the other thread adds stuff into the queue. I want to put the queue processing thread to sleep when its finished processing the queue I want to have the 2nd thread tell it to wake up when it has added an item to the queue However these functions call System.Threading.SynchronizationLockException: Object synchronization method was called from an unsynchronized block of code on the Monitor.PulseAll(waiting); call, because I havent syncronized the function with the waiting object. [which I dont want to do, i want to be able to process while adding items to the queue]. How can I achieve this? Queue<object> items = new Queue<object>(); object waiting = new object(); 1st Thread public void ProcessQueue() { while (true) { if (items.Count == 0) Monitor.Wait(waiting); object real = null; lock(items) { object item = items.Dequeue(); real = item; } if(real == null) continue; .. bla bla bla } } 2nd Thread involves public void AddItem(object o) { ... bla bla bla lock(items) { items.Enqueue(o); } Monitor.PulseAll(waiting); }

• NSOutlineview - strange behavior after reloading data

  - by matei

  I have a NSOutlineView which loads data from a data source. The table is displayed in a panel. The items shown in the table are items which belong to an object (the relation is one-to many between the object and the items). I have a list of objects in a combo box (in fact a NSPopupButton), and when I select another object in the combo box, I want it's items to be shown in the table (the NSOutlineView). I managed to do all this , however when I select another object from the combo box, not all of it's items are displayed. I have put some logging messages in the data source and it seems that there are some items that are being returned from the data source , but are not shown in the table (and are not queried for children). Now the strange part is that when I click the main window (as I said, all that I described here is in a NSPanel loaded on top of the window) , all the data is displayed correctly. It seems as if clicking the main window triggers something in the NSOutlineView that makes it display the missing items, but I can't tell what it is.

• Converting python collaborative filtering code to use Map Reduce

  - by Neil Kodner

  Using Python, I'm computing cosine similarity across items. given event data that represents a purchase (user,item), I have a list of all items 'bought' by my users. Given this input data (user,item) X,1 X,2 Y,1 Y,2 Z,2 Z,3 I build a python dictionary {1: ['X','Y'], 2 : ['X','Y','Z'], 3 : ['Z']} From that dictionary, I generate a bought/not bought matrix, also another dictionary(bnb). {1 : [1,1,0], 2 : [1,1,1], 3 : [0,0,1]} From there, I'm computing similarity between (1,2) by calculating cosine between (1,1,0) and (1,1,1), yielding 0.816496 I'm doing this by: items=[1,2,3] for item in items: for sub in items: if sub >= item: #as to not calculate similarity on the inverse sim = coSim( bnb[item], bnb[sub] ) I think the brute force approach is killing me and it only runs slower as the data gets larger. Using my trusty laptop, this calculation runs for hours when dealing with 8500 users and 3500 items. I'm trying to compute similarity for all items in my dict and it's taking longer than I'd like it to. I think this is a good candidate for MapReduce but I'm having trouble 'thinking' in terms of key/value pairs. Alternatively, is the issue with my approach and not necessarily a candidate for Map Reduce?

• How do I simulate "Is In" using Linq2Sql

  - by flipdoubt

  I often find myself with a list of disconnected Linq2Sql objects or keys that I need to re-select from a Linq2Sql data-context to update or delete in the database. If this were SQL, I would use IS IN in the SQL WHERE clause, but I am stuck with what to do in Linq2Sql. Here is a sample of what I would like to write: public void MarkValidated(IList<int> idsToValidate) { using(_Db.NewSession()) // Instatiates new DataContext { // ThatAreIn <- this is where I am stuck var items = _Db.Items.ThatAreIn(idsToValidate).ToList(); foreach(var item in items) item.Validated = DateTime.Now; _Db.SubmitChanges(); } // Disposes of DataContext } Or: public void DeleteItems(IList<int> idsToDelete) { using(_Db.NewSession()) // Instatiates new DataContext { // ThatAreIn <- this is where I am stuck var items = _Db.Items.ThatAreIn(idsToValidate); _Db.Items.DeleteAllOnSubmit(items); _Db.SubmitChanges(); } // Disposes of DataContext } Can I get this done in one trip to the database? If so, how? Is it possible to send all those ints to the database as a list of parameters and is that more efficient than doing a foreach over the list to select each item one at a time?

• Moq, a translator and an expression

  - by jeriley

  I'm working with an expression within a moq-ed "Get Service" and ran into a rather annoying issue. In order to get this test to run correctly and the get service to return what it should, there's a translator in between that takes what you've asked for, sends it off and gets what you -really- want. So, thinking this was easy I attempt this ... the fakelist is the TEntity objects (translated, used by the UI) and TEnterpriseObject is the actual persistance. mockGet.Setup(mock => mock.Get(It.IsAny<Expression<Func<TEnterpriseObject, bool>>>())).Returns( (Expression<Func<TEnterpriseObject, bool>> expression) => { var items = new List<TEnterpriseObject>(); var translator = (IEntityTranslator<TEntity, TEnterpriseObject>) ObjectFactory.GetInstance(typeof (IEntityTranslator<TEntity, TEnterpriseObject>)); fakeList.ForEach(fake => items.Add(translator.ToEnterpriseObject(fake))); items = items.Where(expression); var result = new List<TEnterpriseObject>(items); fakeList.Clear(); result.ForEach(item => translator.ToEntity(item)); return items; }); I'm getting the red squigglie under there items.where(expression) -- says it can't be infered from usage (confused between <Func<TEnterpriseObject,bool>> and <Func<TEnterpriseObject,int,bool>>) A far simpler version works great ... mockGet.Setup(mock => mock.Get(It.IsAny<Expression<Func<TEntity, bool>>>())).Returns( (Expression<Func<TEntity, bool>> expression) => fakeList.AsQueryable().Where(expression)); so I'm not sure what I'm missing... ideas?

• How to build a JSON response by combining @foo.to_json(options) and @bars.to_json(options) in Rails

  - by smotchkkiss

  First, the desired result I have User and Item models. I'd like to build a JSON response that looks like this: { "user": {"username":"Bob!","foo":"whatever","bar":"hello!"}, "items": [ {"id":1, "name":"one", "zim":"planet", "gir":"earth"}, {"id":2, "name":"two", "zim":"planet", "gir":"mars"} ] } However, my User and Item model have more attributes than just those.

• How to access empty ASP.NET ListView.ListViewItem to apply a style after all databinding is done?

  - by Caroline S.

  We're using a ListView with a GroupTemplate to create a three-column navigation menu with six items in each column, filling in two non-data-bound rows in the last column with an EmptyItemTemplate that contains an empty HTML list item. That part works fine, but I also need to programmatically add a CSS class to the sixth (last) item in each column. That part is also working fine for the first two columns because I'm assigning the CSS class in the DataBound event, where I can iterate through the ListView.Items collection and access the sixth item in the first two columns by using a modulus operator and counter. The problem comes in the last column, where the EmptyItemTemplate has correctly filled in two empty list items, to the last of which I also need to add this CSS class. The empty items are not included in the ListView.Items collection (that's just ListViewDataItems, and the empty items are ListViewItems). I cannot find a way to access the entire collection of ListViewItems after binding. Am I missing something? I know I can access the empty items during ItemCreated, but I can't figure out how to determine where the item I'm creating falls in the flow, and whether it's the last one. Any help would be appreciated, if this can even be done -- I'm a bit stuck.

• SubSonic generated code and always filtering records

  - by cmroanirgo

  Hi, I have a table called "Users" that has a column called "deleted", a boolean indicating that the user is "Deleted" from the system (without actually deleting it, of course). I also have a lot of tables that have a FK to the Users.user_id column. Subsonic generates (very nicely) the code for all the foreign keys in a similar manner: public IQueryable<person> user { get { var repo=user.GetRepo(); return from items in repo.GetAll() where items.user_id == _user_id select items; } } Whilst this is good and all, is there a way to generate the code in such a way to always filter out the "Deleted" users too? In the office here, the only suggestion we can think of is to use a partial class and extend it. This is obviously a pain when there are lots and lots of classes using the User table, not to mention the fact that it's easy to inadvertently use the wrong property (User vs ActiveUser in this example): public IQueryable<User> ActiveUser { get { var repo=User.GetRepo(); return from items in repo.GetAll() where items.user_id == _user_id and items.deleted == 0 select items; } } Any ideas?

• ASP.NET Bind to IEnumerable

  Hi, I'm passing a the type IEnumerable to my view, and for each item I output a html.textbox to enter the details into.

  In my outlook I have 1 exchange connection and 2 Personal Folders. I want to go fetch ALL items from the calendars and contacts so I use: /** * Create outlook application */ Outlook.Application oApp = new Outlook.Application(); Outlook.NameSpace oNS = oApp.GetNamespace("mapi"); oNS.Logon(Missing.Value, Missing.Value, true, true); /** * Loop through all the folders */ foreach (Outlook.MAPIFolder oFolder in oNS.Folders) { if (oFolder.Name == "Public Folders") { break; } /** * Get calendar items */ //Outlook.MAPIFolder oCalendar = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderCalendar); Outlook.MAPIFolder oCalendar = oFolder.Folders[5]; Outlook.Items oCalendarItems = oCalendar.Items; //Outlook.MAPIFolder oContacts = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderContacts); Outlook.MAPIFolder oContacts = oFolder.Folders[7]; Outlook.Items oContactItems = oContacts.Items; But this does not work oFolder.Folders[5] is not always 5 for the calendar, sometimes it's a different value. I cannot find the items by name oFolder.Folders["Calendar"]; because in Dutch the folder will be named "Agenda". Usually I use: Outlook.MAPIFolder oCalendar = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderCalendar); But then I only get the default calendar. How can I get the other calendars?

• C++/Qt - Memory allocation question

  - by HardCoder1986

  Hello! I recently started investigating Qt for myself and have the following question: Suppose I have some QTreeWidget* widget. At some moment I want to add some items to it and this is done via the following call: QList<QTreeWidgetItem*> items; // Prepare the items QTreeWidgetItem* item1 = new QTreeWidgetItem(...); QTreeWidgetItem* item2 = new QTreeWidgetItem(...); items.append(item1); items.append(item2); widget->addTopLevelItems(items); So far it looks ok, but I don't actually understand who should control the objects' lifetime. I should explain this with an example: Let's say, another function calls widget->clear();. I don't know what happens beneath this call but I do think that memory allocated for item1 and item2 doesn't get disposed here, because their ownage wasn't actually transfered. And, bang, we have a memory leak. The question is the following - does Qt have something to offer for this kind of situation? I could use boost::shared_ptr or any other smart pointer and write something like shared_ptr<QTreeWidgetItem> ptr(new QTreeWidgetItem(...)); items.append(ptr.get()); but I don't know if the Qt itself would try to make explicit delete calls on my pointers (which would be disastrous since I state them as shared_ptr-managed). How would you solve this problem? Maybe everything is evident and I miss something really simple?

• Singleton issue causing a buffer overrun

  - by Rudiger

  Hi everyone, Ive created a singleton to store 2 arrays: @interface Globals : NSObject { NSMutableArray *items; NSMutableArray *extras; } + (Globals *)sharedInstance; @property (nonatomic, assign) NSMutableArray *items; @property (nonatomic, assign) NSMutableArray *extras; @end @implementation Globals @synthesize items, extras; + (Globals *)sharedInstance { static Globals *myInstance = nil; @synchronized(self) { if(!myInstance) { myInstance = [[Globals alloc] init]; } } return myInstance; } -(void)dealloc { [items release]; [extras release]; [super dealloc]; } @end When I set the Arrays in the singleton from the App delegate and then output them to NSLog it displays what is expected. But when I call it from a view controller further into the App it displays the first entry fine, some of the second entry and then garbage which is i assume a buffer overrun, sometimes it also crashes. I set the singleton array in the appDelegate like so: Globals *sharedInstance = [Globals sharedInstance]; [sharedInstance setItems:items]; and retrieve it: [[[sharedInstance items] objectAtIndex:indexPath.row] objectForKey:@"name"]; cell.description.text = [[[sharedInstance items] objectAtIndex:indexPath.row] objectForKey:@"description"]; Name works fine in both cells if there is 2, description works in the first case, never in the second case. Is it because the arrays in my singleton aren't static? If so why is it outputting the first entry fine? Cheers for any help.
