  • Two Objects created with the same Address in Flex

    - by James
    Hi, I have an issue in flex which is causing a bit of a headache! I am adding objects to an ArrayCollection but in doing so, another ArrayCollection is also picking up these changes even though there is no binding occurring. I can see from the debug that the two ACs have the same address but for the life of me can't figure out why. I have two Array Collections: model.index.rows //The main array collection model.index.holdRows //The array collection that imitates the above This phantom data binding occurs only for the first iteration in the loop and for all others it will just write it the once. The reason this is proving troublesome is that it creates duplicate entries in my datagrid. public override function handleMessage(message:IMessage):void { super.handleMessage(message); if (message is IndexResponse) { var response:IndexResponse = message as IndexResponse; model.index.rows.removeAll(); model.index.indexIsEmpty = response.nullIndex; if (model.index.indexIsEmpty !== true) { //Update the index model from the response. Note: each property of the row object will be shown in the UI as a column in the grid response.index.forEach(function(entry:EntryData, i:int, a:Array):void { var row:Object = { fileID: entry.fileID, dadName: entry.dadName }; entry.tags.forEach(function(tag:Tag, i:int, a:Array):void { row[tag.name] = tag.value; }); model.index.rows.addItem(row); }); if(model.index.indexForNetworkView == true){ model.index.holdRows.source = model.index.holdRows.source.concat(model.index.rows.source); model.index.indexCounter++; model.index.indexForNetworkView = false; controller.indexController.showNetwork(model.index.indexCounter); } model.index.rows.refresh(); controller.networkController.show(); } } Has anyone else who has encountered something simillar propose a solution?

  • Determining if an unordered vector<T> has all unique elements

    - by Hooked
    Profiling my cpu-bound code has suggested I that spend a long time checking to see if a container contains completely unique elements. Assuming that I have some large container of unsorted elements (with < and = defined), I have two ideas on how this might be done: The first using a set: template <class T> bool is_unique(vector<T> X) { set<T> Y(X.begin(), X.end()); return X.size() == Y.size(); } The second looping over the elements: template <class T> bool is_unique2(vector<T> X) { typename vector<T>::iterator i,j; for(i=X.begin();i!=X.end();++i) { for(j=i+1;j!=X.end();++j) { if(*i == *j) return 0; } } return 1; } I've tested them the best I can, and from what I can gather from reading the documentation about STL, the answer is (as usual), it depends. I think that in the first case, if all the elements are unique it is very quick, but if there is a large degeneracy the operation seems to take O(N^2) time. For the nested iterator approach the opposite seems to be true, it is lighting fast if X[0]==X[1] but takes (understandably) O(N^2) time if all the elements are unique. Is there a better way to do this, perhaps a STL algorithm built for this very purpose? If not, are there any suggestions eek out a bit more efficiency?

  • Sql Server 2005 multiple insert with c#

    - by bottlenecked
    Hello. I have a class named Entry declared like this: class Entry{ string Id {get;set;} string Name {get;set;} } and then a method that will accept multiple such Entry objects for insertion into the database using ADO.NET: static void InsertEntries(IEnumerable<Entry> entries){ //build a SqlCommand object using(SqlCommand cmd = new SqlCommand()){ ... const string refcmdText = "INSERT INTO Entries (id, name) VALUES (@id{0},@name{0});"; int count = 0; string query = string.Empty; //build a large query foreach(var entry in entries){ query += string.Format(refcmdText, count); cmd.Parameters.AddWithValue(string.Format("@id{0}",count), entry.Id); cmd.Parameters.AddWithValue(string.Format("@name{0}",count), entry.Name); count++; } cmd.CommandText=query; //and then execute the command ... } } And my question is this: should I keep using the above way of sending multiple insert statements (build a giant string of insert statements and their parameters and send it over the network), or should I keep an open connection and send a single insert statement for each Entry like this: using(SqlCommand cmd = new SqlCommand(){ using(SqlConnection conn = new SqlConnection(){ //assign connection string and open connection ... cmd.Connection = conn; foreach(var entry in entries){ cmd.CommandText= "INSERT INTO Entries (id, name) VALUES (@id,@name);"; cmd.Parameters.AddWithValue("@id", entry.Id); cmd.Parameters.AddWithValue("@name", entry.Name); cmd.ExecuteNonQuery(); } } } What do you think? Will there be a performance difference in the Sql Server between the two? Are there any other consequences I should be aware of? Thank you for your time!

  • How to cache code in PHP?

    - by Janis Peisenieks
    I am creating a custom form building system, which includes various tokens. These tokens are found using Regular Expressions, and depending on the type of toke, parsed. Some require simple replacement, some require cycles, and so forth. Now I know, that RegExp is quite resource and time consuming, so I would like to be able to parse the code for the form once, creating a php code, and then save the PHP code, for next uses. How would I go about doing this? So far I have only seen output caching. Is there a way to cache commands like echo and cycles like foreach()? Because of misunderstandings, I'll create an example. Unparsed template data: Thank You for Your interest, [*Title*] [*Firstname*] [*Lastname*]. Here are the details of Your order! [*KeyValuePairs*] Here is the link to Your request: [*LinkToRequest*]. Parsed template: "Thank You for Your interest, <?php echo $data->title;?> <?php echo $data->firstname;?> <?php echo $data->lastname;?>. Here are the details of Your order! <?php foreach($data->values as $key=>$value){ echo $key."-".$value }?> Here is the link to Your request: <?php echo $data->linkToRequest;?>. I would then save the parsed template, and instead of parsing the template every time, just pass the $data variable to the already parsed one, which would generate an output.

  • Resize iframe to show first element works except in IE 7

    - by Rob Fenwick
    I have two iframes on my home page, the script below is in the head of the page that is being displayed in the iframe, there are several divisions on the page in a container div with an id of 'content', I want to size the iframe on the home page so that just the first div is initially seen and to scroll to see the rest. It is working in all browsers that I have tried except IE 7, I don't care too much about earlier browsers. IE 7 is acting like the page being shown is blank and sizing the iframe to 0 height, can someone tell me why IE 7 is having a problem with it, and failing that how can I get IE 7 to ignore the script? function resizeIframe() { //get the firstChild of a container div with the id 'content' var div01 = document.getElementById("content").firstChild; //find the first element ignoring white spaces and returns while(div01.nodeType!=1){ div01 = div01.nextSibling; } // get the height of first element var boxHeight = div01.clientHeight; //set the height of iframe the id of the iframe is 'news' parent.document.getElementById('news').height = boxHeight; } I have the function called in the body tag. If someone could help me I'd very much appreciate it. The page that it is on is at wsuu.org The version with the script is not up but you can get an idea of what I'm trying to do. Rob

  • What is the difference between these two linq implementations?

    - by Mahesh Velaga
    I was going through Jon Skeet's Reimplemnting Linq to Objects series. In the implementation of where article, I found the following snippets, but I don't get what is the advantage that we are gettting by splitting the original method into two. Original Method: // Naive validation - broken! public static IEnumerable<TSource> Where<TSource>( this IEnumerable<TSource> source, Func<TSource, bool> predicate) { if (source == null) { throw new ArgumentNullException("source"); } if (predicate == null) { throw new ArgumentNullException("predicate"); } foreach (TSource item in source) { if (predicate(item)) { yield return item; } } } Refactored Method: public static IEnumerable<TSource> Where<TSource>( this IEnumerable<TSource> source, Func<TSource, bool> predicate) { if (source == null) { throw new ArgumentNullException("source"); } if (predicate == null) { throw new ArgumentNullException("predicate"); } return WhereImpl(source, predicate); } private static IEnumerable<TSource> WhereImpl<TSource>( this IEnumerable<TSource> source, Func<TSource, bool> predicate) { foreach (TSource item in source) { if (predicate(item)) { yield return item; } } } Jon says - Its for eager validation and then defferring for the rest of the part. But, I don't get it. Could some one please explain it in a little more detail, whats the difference between these 2 functions and why will the validations be performed in one and not in the other eagerly? Conclusion/Solution: I got confused due to my lack of understanding on which functions are determined to be iterator-generators. I assumed that, it is based on signature of a method like IEnumerable<T>. But, based on the answers, now I get it, a method is an iterator-generator if it uses yield statements.

  • Jquery find first visible element after horizontal scroll

    - by lolo flores
    I’m new (only two weeks old) in Jquery, so please bear with me. I know that a very similar question was asked some time ago but I do not know how to adapt the answer to my problem. I have a very wide multicolumn layout something like this: | aaaa | bbbb | cccc | … | | aaaa | b | cc | … | | aaa | cccc | ddd | … | The code looks like: <div id="container"> <p>aaaaaaaaaaa</p> <p>bbbbb</p> <p>ccccccccccc</p> <p>dddddddddd</p> ... <p>xxxxxx</p> </div> There is no vertical scrolling and the container width is set in such a way that only two columns are shown. The user scrolls left or right to see the relevant text. What I want is to get the position currently on display, store it (maybe in a cookie) and retrieve it the next time the user opens the page. I think that I need a way of finding out what paragraph is currently the left-top most, but other suggestions are very welcome. Any ideas? btw: this is an internal project, so Mozilla only :-) Thanks Lolo

  • C# Combining lines

    - by Mike
    Hey everybody, this is what I have going on. I have two text files. Umm lets call one A.txt and B.txt. A.txt is a config file that contains a bunch of folder names, only 1 listing per folder. B.txt is a directory listing that contains folders names and sizes. But B contains a bunch of listing not just 1 entry. What I need is if B, contains A. Take all lines in B that contain A and write it out as A|B|B|B ect.... So example: A.txt: Apple Orange Pear XBSj HEROE B.txt: Apple|3123123 Apple|3434 Orange|99999999 Orange|1234544 Pear|11 Pear|12 XBSJ|43949 XBSJ|43933 Result.txt: Apple|3123123|3434 Orange|99999999|1234544 Pear|11|12 XBSJ|43949|43933 This is what I had but it's not really doing what I needed. string[] combineconfig = File.ReadAllLines(@"C:\a.txt"); foreach (string ccline in combineconfig) { string[] readlines = File.ReadAllLines(@"C:\b.txt"); if (readlines.Contains(ccline)) { foreach (string rdlines in readlines) { string[] pslines = rdlines.Split('|'); File.AppendAllText(@"C:\result.txt", ccline + '|' + pslines[0]); } } I know realize it's not going to find the first "if" because it reads the entire line and cant find it. But i still believe my output file will not contain what I need.

  • KO3: How to deal with stylesheets and scriptfiles

    - by Svish
    I'm using Kohana 3 and it's template controller. My main site template controller currently looks something like this: <?php defined('SYSPATH') or die('No direct script access.'); abstract class Controller_SiteTemplate extends Controller_Template { public function before() { parent::before(); // Initialize default template variables $this->template->styles = Kohana::config('site.styles'); $this->template->scripts = Kohana::config('site.scripts'); $this->template->title = ''; $this->template->content = ''; } } And then in my template view I do: <?php # Styles foreach($styles as $file => $media) echo HTML::style($file, array('media' => $media)).PHP_EOL ?> <?php # Scripts foreach($scripts as $file) echo HTML::script($file).PHP_EOL ?> This works alright. The problem is that it requires the style- and script files to be added in the controller, which shouldn't really have to care about those. It also makes it a hassle if the views are done by someone else than me since they would have to fool around with the controller just to add a new stylesheet or a new script file. How can this be done in a better way? Just to clearify, what I am wondering is how to deal with page specific stylesheets and scripts. The default and site-wide ones I have no problem with fetching from a config file or just put directly in the template view. My issue is how to add custom ones for specific pages in a good way.

  • whats a sure shot way to make sure objects appear correctly positioned on stage

    - by dubbeat
    Hi, I've being having a lot of trouble recently getting objects (UIComponents containing movieclips) to appear correctly in the right positions. For example, my current dilema is I have a container that is 3 layers deep. outer layer inner layer display layer This hiearachy was built in CS4 as a movieclip. In the display layer in CS4 I figured out where I want to place 16 different "box" movieclips. I dont want to create these boxes maunually at design time, instead I want to add them at run time. So I know what container I want to add my boxes to. I know what positions they "would" be at in CS4 environment. Whats the best way to add them in the correct locations with code? The "box" I'm trying to add in a movieclip held inside of a UIComponent. Is there a "rule of thumb" to do this type of thing? I'm sure I'm going to encounter this problem again and again and I'd like to just blow the problem out of the water once and for all with the "right way" to do this.

  • Avoiding duplicate objects in Java deserialization

    - by YGL
    I have two lists (list1 and list2) containing references to some objects, where some of the list entries may point to the same object. Then, for various reasons, I am serializing these lists to two separate files. Finally, when I deserialize the lists, I would like to ensure that I am not re-creating more objects than needed. In other words, it should still be possible for some entry of List1 to point to the same object as some entry in List2. MyObject obj = new MyObject(); List<MyObject> list1 = new ArrayList<MyObject>(); List<MyObject> list2 = new ArrayList<MyObject>(); list1.add(obj); list2.add(obj); // serialize to file1.ser ObjectOutputStream oos = new ObjectOutputStream(...); oos.writeObject(list1); oos.close(); // serialize to file2.ser oos = new ObjectOutputStream(...); oos.writeObject(list2); oos.close(); I think that sections 3.4 and A.2 of the spec say that deserialization strictly results in the creation of new objects, but I'm not sure. If so, some possible solutions might involve: Implementing equals() and hashCode() and checking references manually. Creating a "container class" to hold everything and then serializing the container class. Is there an easy way to ensure that objects are not duplicated upon deserialization? Thanks.

  • Printing in Silverlight 4

    - by Number8
    Hello, We have an application structured roughly like this: <Grid x:Name="LayoutRoot"> <ScrollViewer> <Canvas x:Name="canvas"> <StackPanel> < Button /><Slider /><Button /></StackPanel> <custom:Blob /> <custom:Blob /> <custom:Blob /> </Canvas> </ScrollViewer> </Grid> Each Blob consists of 1 or more rectangles, lines, and text boxes; they are positioned anywhere on the canvas. If I print the document using the LayoutRoot: PrintDocument pd = new PrintDocument(); pd += (s, pe) => { pe.PageVisual = LayoutRoot; }; pd.Print("Blobs"); ... it is like a print-screen -- the scrollbars, the sliders, the blobs that are visible -- are printed. If I set PageVisual = canvas, nothing is printed. How can I get all the blob objects, and just those objects, to print? Do I need to copy them into another container, and give that container to PageVisual? Can I use a ViewBox to make sure they all fit on one page? Thanks for any pointers....

  • How can I refactor this to work without breaking the pattern horribly?

    - by SnOrfus
    I've got a base class object that is used for filtering. It's a template method object that looks something like this. public class Filter { public void Process(User u, GeoRegion r, int countNeeded) { List<account> selected = this.Select(u, r, countNeeded); // 1 List<account> filtered = this.Filter(selected, u, r, countNeeded); // 2 if (filtered.Count > 0) { /* do businessy stuff */ } // 3 if (filtered.Count < countNeeded) this.SendToSuccessor(u, r, countNeeded - filtered) // 4 } } Select(...), Filter(...) are protected abstract methods and implemented by the derived classes. Select(...) finds objects in the based on x criteria, Filter(...) filters those selected further. If the remaining filtered collection has more than 1 object in it, we do some business stuff with it (unimportant to the problem here). SendToSuccessor(...) is called if there weren't enough objects found after filtering (it's a composite where the next class in succession will also be derived from Filter but have different filtering criteria) All has been ok, but now I'm building another set of filters, which I was going to subclass from this. The filters I'm building however would require different params and I don't want to just implement those methods and not use the params or just add to the param list the ones I need and have them not used in the existing filters. They still perform the same logical process though. I also don't want to complicated the consumer code for this (which looks like this) Filter f = new Filter1(); Filter f2 = new Filter2(); Filter f3 = new Filter3(); f.Sucessor = f2; f2.Sucessor = f3; /* and so on adding filters as successors to previous ones */ foreach (User u in users) { foreach (GeoRegion r in regions) { f.Process(u, r, ##); } } How should I go about it?

  • Ignore a css class applied to a parent table

    <table class="table table-bordered table-hover table-condensed data_table"> <tbody data-bind="foreach: outboundFaxLogs"> <tr> </tr> <tr> <td></td> <td colspan="8"> <table> <tr style="border:none"> <td>ReFax Status</td> <td>FaxTo</td> <td>Completion</td> <td>FaxID</td> </tr> <tbody data-bind="foreach: ResubmissionHistory""> <tr style="border:none"> <td data-bind="text: Status" ></td> <td data-bind="text: FaxToNbr"></td> <td data-bind="text: $root.formatDateTime(CompletionTime)"></td> <td data-bind="text: OutboundFaxLogId"></td> </tr> </tbody> </table> </td> </tr> </tbody> </table> The parent table has a css class applied to it which is table-bordered. Its a twitter bootstrap style element. I don't want that style to be applied to the child table. How can I do this ? I do not want the lines that appear in between the table cells for the child table.

  • Analyzing an IronPython Scope

    - by Vercinegetorix
    I'm trying to write C# code with an embedded IronPython script. Then want to analyze the contents of the script, i.e. list all variables, functions, class and their members/methods. There's an easy way to start, assuming I've got a scope defined and code executed in it already: dynamic variables=pyScope.GetVariables(); foreach (string v in variables) { dynamic dynamicV=pyScope.GetVariable(); /*seems to return everything. variables, functions, classes, instances of classes*/ } But how do I figure out what the type of a variable is? For the following python 'objects', dynamicV.GetType() will return different values: x=5 --system.Int32 y="asdf" --system.String def func():... --IronPython.Runtime.PythonFunction z=class() -- IronPython.Runtime.Types.OldInstance, how can I identify what the actual python class is? class NewClass -- throws an error, GetType() is unavailable. This is almost what I'm looking for. I could capture the exception thrown when unavailable and assume it's a class declaration, but that seems unclean. Is there a better approach? To discover the members/methods of a class it looks like I can use: ObjectOperations op = pyEngine.Operations; object instance = op.Call("className"); foreach (string j in op.GetMemberNames("className")) { object member=op.GetMember(instance, j); Console.WriteLine(member.GetType()); /*once again, GetType() provides some info about the type of the member, but returns null sometimes*/ } Also, how do I get the parameters to a method? Thanks!

  • Which method of 'clearfix' is best?

    - by Pickledegg
    I have the age old problem of a div wrapping a 2 column layout. My sidebar is floated so my container div fails to wrap the content & sidebar. <div id="container"> <div id="content"> </div> <div id="sidebar"> </div> </div> There seem to be numerous methods of fixing the clear bug in FF: <br clear="all"/> overflow:auto overflow:hidden etc. But in my situation, the only one that seems to work correctly is the <br clear="all"/> solution, which is a little bit scruffy. overflow:auto gives me nasty scrollbars, and overflow:hidden must surely have side effects. Also, apparently IE7 is supposed to not suffer from this problem due to its incorrect behaviour, but again, in my situation its suffering the same as FF. Whats the most reliable/best practice method currently available to us?

  • ListView setOnItemClickListener in ListFragment not working

    - by Siddarth Kaki
    I am developing an app that uses ActionBar tabs to display a list of options through ListFragment. The list (and ListFragment) display without a problem, but the ListView's setOnItemClickListener doesn't seems to work, as nothing happens when an item in the list is clicked. Here's the code for the ListFragment class: package XXX.XXX; public class AboutFrag extends SherlockListFragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.aboutfrag, container, false); ListView lv = (ListView) view.findViewById(android.R.id.list); String[] items = new String[] {"About 1", "About 2", "About 3"}; lv.setAdapter(new ArrayAdapter<String>(getActivity(), R.layout.list_item, items)); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View view, int position, long id) { switch (position) { case 0: Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://google.com")); startActivityForResult(browserIntent, 0); break; case 1: Intent browserIntent2 = new Intent(Intent.ACTION_VIEW, Uri.parse("http://wikipedia.org")); startActivityForResult(browserIntent2, 0); break; case 2: Intent browserIntent3 = new Intent(Intent.ACTION_VIEW, Uri.parse("http:/android.com"); startActivityForResult(browserIntent3, 0); break; } } }); return view; } } I'm assuming it does not work because the class returns the view object, so the FragmentActivity can't run the listener code, so does anyone know how to make this work? By the way, I am using ActionBarSherlock. Thanks in advance!!!

  • How to do "map chunks", like terraria or minecraft maps?

    - by O'poil
    Due to performance issues, I have to cut my maps into chunks. I manage the maps in this way: listMap[x][y] = new Tile (x,y); I tried in vain to cut this list for several "chunk" to avoid loading all the map because the fps are not very high with large map. And yet, when I update or Draw I do it with a little tile range. Here is how I proceed: foreach (List<Tile> list in listMap) { foreach (Tile leTile in list) { if ((leTile.Position.X < screenWidth + hero.Pos.X) && (leTile.Position.X > hero.Pos.X - tileSize) && (leTile.Position.Y < screenHeight + hero.Pos.Y) && (leTile.Position.Y > hero.Pos.Y - tileSize) ) { leTile.Draw(spriteBatch, gameTime); } } } (and the same thing, for the update method). So I try to learn with games like minecraft or terraria, and any two manages maps much larger than mine, without the slightest drop of fps. And apparently, they load "chunks". What I would like to understand is how to cut my list in Chunk, and how to display depending on the position of my character. I try many things without success. Thank you in advance for putting me on the right track! Ps : Again, sorry for my English :'( Pps : I'm not an experimented developer ;)

  • StructureMap Configuration Per Thread/Request for the Full Dependency Chain

    - by Phil Sandler
    I've been using Structuremap for a few months now, and it has worked great on some smaller (green field) projects. Most of the configurations I have had to set up involve a single implementation per interface. In the cases where I needed to choose a specific implementation at runtime, I created a factory class that used ObjectFactory.GetNamedInstance<(). In the smaller projects, there were few enough of these cases where I was comfortable with the references to ObjectFactory. My understanding is that you want to limit these references as much as possible, and ideally only reference the ObjectFactory once. I am working to refactor a larger codebase to use IOC/StructureMap, and am finding that I may need many of these factory classes with ObjectFactory references to get what I need. Essentially, I am creating a "root service" with the ObjectFactory, so that everything in the dependency chain is managed by the container. The root service is created by name (i.e. "BuildCar", "BuildTruck"), and the services needed deeper in the dependency chain could also be constructed using the same name--so the "IAttachWheels" service could vary based on whether a car or truck is being built. Since the class that depends on IAttachWheels is the same in both configurations, I don't think I can use ConstructedBy in the registry to choose the implementation. Also, to be clear, the IAttachWheels implementations need to be managed by the container as well, because the dependency chain runs fairly deep. I looked briefly at Profiles as an option, but read (here on StackOverflow) that changing profiles essentially changes implementations for all threads. Is there a feature that is similar to profiles that is thread/request specific? Is the factory class that references ObjectFactory approach the right way to go? Any thoughts would be appreciated.

  • entity framework navigation property further filter without loading into memory

    - by cellik
    Hi, I've two entities with 1 to N relation in between. Let's say Books and Pages. Book has a navigation property as Pages. Book has BookId as an identifier and Page has an auto generated id and a scalar property named PageNo. LazyLoading is set to true. I've generated this using VS2010 & .net 4.0 and created a database from that. In the partial class of Book, I need a GetPage function like below public Page GetPage(int PageNumber) { //checking whether it exist etc are not included for simplicity return Pages.Where(p=>p.PageNo==PageNumber).First(); } This works. However, since Pages property in the Book is an EntityCollection it has to load all Pages of a book in memory in order to get the one page (this slows down the app when this function is hit for the first time for a given book). i.e. Framework does not merge the queries and run them at once. It loads the Pages in memory and then uses LINQ to objects to do the second part To overcome this I've changed the code as follows public Page GetPage(int PageNumber) { MyContainer container = new MyContainer(); return container.Pages.Where(p=>p.PageNo==PageNumber && p.Book.BookId==BookId).First(); } This works considerably faster however it doesn't take into account the pages that have not been serialized to the db. So, both options has its cons. Is there any trick in the framework to overcome this situation. This must be a common scenario where you don't want all of the objects of a Navigation property loaded in memory when you don't need them.

  • jQuery - Compatibility Problem with Internet Explorer 7 and Opera

    - by Marius
    Hello there, I have this counter which counts + 1 every time somebody shares content from the site. When it happens, the social icon that was clicked will bounce. It works in Firefox,Chrome, IE8, and Opera, however the bouncing animation is wrong in opera. $.fn.countExternal = function(animSpeed, num) { // for each counter this.each(function(){ // select all the digit containers var span = $(this).children(); // count the num of digit containers var len = $(span).length; // get the current count u = $(span).text(); // copy variable and add increment(s) v = num + ''; // foreach digit container... for (i=v.length - 1; i >= 0; i--) { // ...check which digits are not affected by the increment(s) if (v.charAt(i) == u.charAt(i)) { break; } } // slice from the total number of digit containers the digits containers which needs updating. slce = len - (v.length - (i + 1)) var updates = $(span).slice(slce); // loop through each digit container and fade out ... $(updates).fadeTo(animSpeed, 0,function(){ $(updates).each(function(index){ f = i + 1 + index; // ...then pick the right digit and update the digit... $(this).text(v.charAt(f)); // ...before fading back in. Cycle complete. $(this).fadeTo(animSpeed, 1); }); }); }); }; }) (jQuery); Demo (NSFW) is here (look underneath the social sharing icons). Any idea how I can solve the IE, and possibly the Opera compatibility problem? Thank you for your time.

    Assuming a table such as: UID Name Datetime Users 4 Room 4 2012-08-03 14:00:00 3 2 Room 2 2012-08-03 14:00:00 3 3 Room 3 2012-08-03 14:00:00 1 1 Room 1 2012-08-03 14:00:00 2 3 Room 3 2012-08-03 14:15:00 1 2 Room 2 2012-08-03 14:15:00 4 1 Room 1 2012-08-03 14:15:00 3 1 Room 1 2012-08-03 14:30:00 6 1 Room 1 2012-08-03 14:45:00 3 2 Room 2 2012-08-03 14:45:00 7 3 Room 3 2012-08-03 14:45:00 8 4 Room 4 2012-08-03 14:45:00 4 I wanted to get the average user count of each room (1,2,3,4) from the time 2PM to 3PM. The problem is that sometimes the room may not "check in" at the 15 minute interval time, so the assumption has to be made that the previous last known user count is still valid. For example the check-in's for 2012-08-03 14:15:00 room 4 never checked in, so it must be assumed that room 4 had 3 users at 2012-08-03 14:15:00 because that is what it had at 2012-08-03 14:00:00 This follows on through so that the average user count I am looking for is as follows: Room 1: (2 + 3 + 6 + 3) / 4 = 3.5 Room 2: (3 + 4 + 4 + 7) / 4 = 4.5 Room 3: (1 + 1 + 1 + 8) / 4 = 2.75 Room 4: (3 + 3 + 3 + 4) / 4 = 3.25 where # is the assumed number based on the previous known check-in. I am wondering if it's possible to so this with SQL alone? if not I am curious of a ingenious PHP solution that isn't just bruteforce math, as such as my quick inaccurate pseudo code: foreach ($rooms_id_array as $room_id) { $SQL = "SELECT * FROM `table` WHERE (`UID` == $room_id && `Datetime` >= 2012-08-03 14:00:00 && `Datetime` <= 2012-08-03 15:00:00)"; $result = query($SQL); if ( count($result) < 4 ) { // go through each date and find what is missing, and then go to previous date and use that instead } else { foreach ($result) $sum += $result; $avg = $sum / 4; } }

  • TreeView Control Problem

    - by ProgNet
    Hi all, I have a public folder on the server that contains recursively nested sub folders. In the various Leaf folders contains Images. I wanted to create a server side file browser that will display the Images to the user. I am using the ASP.NET TreeView Control. I create the tree nodes using PopulateOnDemand. If the user click on a leaf directory I want the images in that folder to be displayed in a DataList Control. The problem is that when I click on a sub tree node (after I expanded it parent node) All the expanded sub tree disappears and only the parent node is showed with no + sign next to it !! ( I have set the TreeView's PopulateNodesFromClient property to true ) Can someone tell me what is the problem ?? Thanks Here is the code : <asp:TreeView ID="TreeView1" runat="server" AutoGenerateDataBindings="False" onselectednodechanged="TreeView1_SelectedNodeChanged" ontreenodepopulate="TreeView1_TreeNodePopulate"> </asp:TreeView> protected void Page_Load(object sender, EventArgs e) { if (!Page.IsPostBack) { string path = Server.MapPath("."); PopulateTopNodes(path); } } private void PopulateTopNodes(string pathToRootFolder) { DirectoryInfo dirInfo = new DirectoryInfo(pathToRootFolder); DirectoryInfo[] dirs = dirInfo.GetDirectories(); foreach (DirectoryInfo dir in dirs) { TreeNode folderNode = new TreeNode(dir.Name,dir.FullName); if (dir.GetDirectories().Length > 0) { folderNode.PopulateOnDemand = true; folderNode.Collapse(); } TreeView1.Nodes.Add(folderNode); } } protected void TreeView1_TreeNodePopulate(object sender, TreeNodeEventArgs e) { if (IsCallback == true) { if (e.Node.ChildNodes.Count == 0) { LoadChildNode(e.Node); } } } private void LoadChildNode(TreeNode treeNode) { DirectoryInfo dirInfo = new DirectoryInfo(treeNode.Value); DirectoryInfo[] dirs = dirInfo.GetDirectories(); foreach (DirectoryInfo dir in dirs) { TreeNode folderNode = new TreeNode(dir.Name, dir.FullName); if(dir.GetDirectories().Length>0){ folderNode.PopulateOnDemand = true; folderNode.Collapse(); } treeNode.ChildNodes.Add(folderNode); } } protected void TreeView1_SelectedNodeChanged(object sender, EventArgs e) { // Retrieve the images here }

  • Reflection and Generics get value of property

    - by GigaPr
    Hi i am trying to implement a generic method which allows to output csv file public static void WriteToCsv<T>(List<T> list) where T : new() { const string attachment = "attachment; filename=PersonList.csv"; HttpContext.Current.Response.Clear(); HttpContext.Current.Response.ClearHeaders(); HttpContext.Current.Response.ClearContent(); HttpContext.Current.Response.AddHeader("content-disposition", attachment); HttpContext.Current.Response.ContentType = "text/csv"; HttpContext.Current.Response.AddHeader("Pragma", "public"); bool isFirstRow = true; foreach (T item in list) { //Get public properties PropertyInfo[] propertyInfo = item.GetType().GetProperties(); while (isFirstRow) { WriteColumnName(propertyInfo); isFirstRow = false; } Type type = typeof (T); StringBuilder stringBuilder = new StringBuilder(); foreach (PropertyInfo info in propertyInfo) { //string value ???? I am trying to get the value of the property info for the item object } HttpContext.Current.Response.Write(stringBuilder.ToString()); HttpContext.Current.Response.Write(Environment.NewLine); } HttpContext.Current.Response.End(); } but I am not able to get the value of the object's property Any suggestion?

  • c# finding matching words in table column using Linq2Sql

    - by David Liddle
    I am trying to use Linq2Sql to return all rows that contain values from a list of strings. The linq2sql class object has a string property that contains words separated by spaces. public class MyObject { public string MyProperty { get; set; } } Example MyProperty values are: MyObject1.MyProperty = "text1 text2 text3 text4" MyObject2.MyProperty = "text2" For example, using a string collection, I pass the below list var list = new List<>() { "text2", "text4" } This would return both items in my example above as they both contain "text2" value. I attempted the following using the below code however, because of my extension method the Linq2Sql cannot be evaluated. public static IQueryable<MyObject> WithProperty(this IQueryable<MyProperty> qry, IList<string> p) { return from t in qry where t.MyProperty.Contains(p, ' ') select t; } I also wrote an extension method public static bool Contains(this string str, IList<string> list, char seperator) { if (String.IsNullOrEmpty(str) || list == null) return false; var splitStr = str.Split(new char[] { seperator }, StringSplitOptions.RemoveEmptyEntries); foreach (string s in splitStr) foreach (string l in list) if (String.Compare(s, l, true) == 0) return true; return false; } Any help or ideas on how I could achieve this?
