  • Autocomplete or Select box? (design problem)

    - by Craig Whitley
    I'm working on a comparison website, so needless to say the search function is the primary feature of the site. I have two input text boxes and a search button. At the moment, the input text boxes use Ajax to query the database and show a drop-down box, but I'm wondering if it would be more intuitive to use a select box instead? The second box is dependant on the first, as when the first is selected theres another ajax query so only the available options for the first selection appear in the autocomplete box. Autocomplete Pros: - "Feels" right? - Looks more appealing than a select box (css design)? Cons: - the user has to be instructed on how to use the search (made to think?) - Only really works off the bat with javascript enabled. - The user may get confused if they type in what they want and no box appears (i.e., no results) Select Box Pros: - Can bring up the list of options / know whats there from the outset. - We use select boxes every day (locations etc.) so we're used to how they work. (more intuitive?) Cons: - Can look a little unaesthetic when theres too many options to choose from. I'm thinking maybe at most around 100 options for my site over time. Any thoughts on how I could go about this would be appreciated!

  • How to find cause and of the SocketException with message that an established connection was aborted

    - by cdpnet
    Hi All, I know the similar question may have been asked many times, but I want to represent the behavior I'm seeing and find if somebody can help predict the cause of this. I am writing a windows service which connects to other windows service over TCP. There are 100 user entities of this, and 5 connections per each. These users perform their tasks using their individual connections. The application goes on withough seeing this problem for 1 or 2 days. Or sometimes show the problem right after starting (-rarely). The best run I had was like 4 to 5 days without showing this exception. And after that application died or I had to stop it for various reasons. I want to know what can be causing this? Here is the stacktrace. System.IO.IOException: Unable to write data to the transport connection: An established connection was aborted by the software in your host machine. ---> System.Net.Sockets.SocketException: An established connection was aborted by the software in your host machine at System.Net.Sockets.Socket.Send(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) at System.Net.Sockets.NetworkStream.Write(Byte[] buffer, Int32 offset, Int32 size) --- End of inner exception stack trace --- at System.Net.Sockets.NetworkStream.Write(Byte[] buffer, Int32 offset, Int32 size) at System.Net.Security._SslStream.StartWriting(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security._SslStream.ProcessWrite(Byte[] buffer, Int32 offset, Int32 count, AsyncProtocolRequest asyncRequest) at System.Net.Security.SslStream.Write(Byte[] buffer, Int32 offset, Int32 count)

  • C# sendkeys problem

    - by user203123
    THe code below I copied from MSDN with a bit of modification: [DllImport("user32.dll", CharSet = CharSet.Unicode)] public static extern IntPtr FindWindow(string lpClassName,string lpWindowName); DllImport("User32")] public static extern bool SetForegroundWindow(IntPtr hWnd); int cnt = 0; private void button1_Click(object sender, EventArgs e) { IntPtr calculatorHandle = FindWindow("Notepad", "Untitled - Notepad"); if (calculatorHandle == IntPtr.Zero) { MessageBox.Show("Calculator is not running."); return; } SetForegroundWindow(calculatorHandle); SendKeys.SendWait(cnt.ToString()); SendKeys.SendWait("{ENTER}"); cnt++; SendKeys.Flush(); System.Threading.Thread.Sleep(1000); } The problem is the number sequence in Notepad is not continuously. The first click always results 0 (as expected). but from the second click, the result is unpredictable (but the sequence is still in order, e.g. 3, 4, 5, 10, 14, 15, ....) If I click the button fast enough, I was able to get the result in continuous order (0,1,2,3,4,....) but sometimes it produces more than 2 same numbers (e.g. 0,1,2,3,3,3,4,5,6,6,6,7,8,9,...) Couldn't understand. Plz enlighten me :) Thanks.

  • Core Data Migration - "Can't add source store" error

    - by Tofrizer
    Hi, In my iPhone app I'm using Core Data and I've made changes to my data model that cannot be automatically migrated over (i.e. added new relationships). I added the data model version (Design - Data Model - Add Model Version) and applied my new data model changes to the new version 2. I then created a mapping object model and set the Source and Destination models to their correct data models (old and new respectively). When I run the app and call the persistentStoreCoordinator, my app barfs with the following: 2010-02-27 02:40:30.922 XXXX[73578:20b] Unresolved error Error Domain=NSCocoaErrorDomain Code=134110 UserInfo=0xfc2240 "Operation could not be completed. (Cocoa error 134110.)", { NSUnderlyingError = Error Domain=NSCocoaErrorDomain Code=134130 UserInfo=0xfbb3a0 "Operation could not be completed. (Cocoa error 134130.)"; reason = "Can't add source store"; } FWIW (not much i think) I've also made the usual code changes in persistentStoreCoordinator to use the NSMigratePersistentStoresAutomaticallyOption and NSInferMappingModelAutomaticallyOption (for future data model changes that can be automatically migrated). More relevantly, my managedObjectModel is created by calling initWithContentsOfURL where the file/resource type is "momd". I've tried updating both the source and destination model in the mapping model (Design - Mapping Model - Update XXX Model) as well as deleted the mapping model and recreated it. I've cleaned and re-built but all to no avail. I still get the above error message. Any pointers/thoughts on how I can further debug or resolve this problem please? I haven't posted any code snippets because this feels much more like a build environment issue (and my code is very standard - just the usual core data code to handle migrations using a mapping model but I'm happy to show the code if it helps). Appreciate any help. Thanks

  • Developing a GPS car tracking system in C#

    - by Click Ok
    I'm in the brainstorming phase to develop a GPS car tracking system requested by a customer. I myself know the directions to build some GPS system to mobile phones and etc. But sincerely I don't know how to start in that project. That is the scenario: 1) The cars will get a device with a SIM CARD that will emit GPS signals. 2) My customer will in any place (home, work, etc) with a web connection will see in the map where the car is located. For me, I have not problems at get the GPS data, convert to usable info and show the position in some map system (like Google Maps or MS Bing Maps, by example). My problem is, how I do to retrieve that "GPS Signal" from device in the car? I will need some kind of "Receiver Device" connected to a web server machine in order to my application to consume that data? Or "automagically" my sodtware will receive the info from a third-party web-service? Or what? I thank for any help!

  • Language+IDE for teaching high school students?

    - by daveagp
    I'm investigating languages and IDEs for a project involving teaching high-school students (around grade 11). It will teach basics of programming as an introduction to computer science (e.g., including how numbers/strings/characters are represented, using procedures and arrays, control flow, a little bit of algorithms, only very basic I/O). The non-negotiable requirements for this project are: a free up-to-date cross-platform IDE (Win & Mac incl. 64-bit) with debug a compiler where it's easy to learn from your mistakes together with the IDE, a gentle installation+learning curve So far, the best options I see are the following. Are there others I should know about? I am giving a short explanation with each one to generally show what I am looking for. In order from most to least promising: Pascal + FreePascal IDE (it seems a little buggy but actively developed?) Python + Eclipse + PyDev (good but features are overwhelming/hard to navigate) Groovy + Eclipse ('') Python + IDLE (looks unnatural to do debugging, to me) Pascal + Lazarus (IDE overwhelming, e.g. not obvious how to "start from scratch") Preferably, as a rule of thumb, the language should be direct enough that you don't need to wrap every program in a class, don't need to reference a System object to println, etc. I tried a little bit to see if there is something in JavaScript or (non-Visual) Basic along the lines of what I want, but found nothing so far. I would say that C/C++/C#, Java, Ruby, Lisp, VB do not fit my criteria for languages for this project. To reiterate my questions: are any of those 5 options really awesome or un-awesome? Are there other options which are even MORE awesome? Anything for Basic or JavaScript which meets all of the criteria? Thanks!

  • jquery Ajax call resulting in Undefined Error in Firefox

    - by Kamal
    Hi I've been pulling my hair out for the last few hours with this problem. And the googling has been hampered by the very vagueness of this. So let me apologise for that first. Basically I'm using jquery and ajax (with C#) to return data from the backend and display that to the screen. The code works perfectly for firefox and IE. But when the data gets too large (??) (1500+ table rows) all I get is an undefined popup. Debugging in firefox (3.6) it doesn't even go into the success method. Worse still it doesn't even go into the error method. A lot of superfluous information there, but I'd rather show everything I'm doing. The Code $j.ajax( { type: "POST", url: "AdminDetails.aspx/LoadCallDetails", data: "{" + data + "}", contentType: "application/json;charset=utf-8", dataType: "json", success: function(msg) { $j("#CallDetailsHolder").html(msg.d); $j(".pointingHand").hide(); var oTable = $j('#dt').dataTable({ "bProcessing": true, "bPaginate": true, "bSort": true, "bAutoWidth": false, "aoColumns": [ { "sType": 'html' }, { "sType": 'custdate' }, { "sType": 'html-numeric' }, { "sType": 'ariary' }, { "sType": 'html' }, { "sType": 'html' } ], "oLanguage": { "sProcessing": "Traitement...", "sLengthMenu": "_MENU_ Montrer", "sZeroRecords": "Aucun enregistrement", "sInfo": "_START_ à _END_ de _TOTAL_", "sInfoEmpty": "0 à 0 de 0", "sInfoFiltered": "(filtrée à partir de _MAX_ )", "sInfoPostFix": "", "sSearch": "Rechercher", "sUrl": "", "oPaginate": { "sFirst": "premier", "sPrevious": "Précédent", "sNext": "suivant", "sLast": "dernier" } }, "sDom": 'T<"clear">lfrtip' }); $j('#CompteBlocRight0').unblock(); $j('#btnRangeSearch').click(function() { oTable.fnDraw(); }); }, error: function(msg) { DisplayError(msg); $j('#CompteBlocRight0').unblock(); } }); //$.ajax } The code definitely works. And even displays in IE without any issues. Any help???

  • SubmitChanges doesn't save but removes inserts from change set, no errors

    - by winston schröder
    Hi Everybody, I have a deeper question regarding debug functionality of Linq to Sql SubmitChanges() Function. I want to save a record in a table of a locally cached db (localdbcache: server SqlExpress 2008 client SqlCE). Before calling SubmitChanges I can find the new item via DataContext.GetChangeSet(). After calling Submit Changes, the items to insert have been removed from the ChangeSet. (That's what this function is supposed to do.) There are no Changes Conflicts and no error in the db's log output. No Exception at all. The table's Count stays at the same value. if ((e.Parameter == null) || (!e.Parameter.GetType().Equals(typeof(LibDB.Client.Vehicles)))) return; LibDB.Client.Vehicles tmp = e.Parameter as LibDB.Client.Vehicles; try { ChangeSet cs = this._dc.GetChangeSet(); if ((tmp == null) || (this._dc == null)) return; if (this._dc.Vehicles.Where(veh => veh.Vin == tmp.Vin).Count() == 0) this._dc.Vehicles.InsertOnSubmit(tmp); else if (this._dc.Vehicles.Where(veh => veh.Vin == tmp.Vin).Count() == 1) this._dc.Vehicles.Attach(tmp, true); else return; using (TransactionScope ts = new TransactionScope()) { try { this._dc.SubmitChanges(); //this._dc.Refresh(RefreshMode.OverwriteCurrentValues, this._dc.Vehicles); } catch (Exception ex) { Console.WriteLine(ex.Message); } } if (this._dc.Vehicles.Where(veh => veh.Vin == tmp.Vin).Count() == 1) MessageBox.Show("Vehicle not saved."); this.vehSelector.ResetLayout(); } I would appreciate any help since I'm loosing hope to find any error, Thanks in Advance Winston

  • WPF Datagrid set the column values only when the row is left

    - by Noam
    Hello I have a simple class. When I use it in winforms binding, whenever I change a value of a cell and leave the cell, the property immediately get changed. Using WPF Datagrid, whenever i change a value of a cell, the property gets set only after I leave the row. That is problematic for me. What am I doing wrong? Here is my code: public class MyClass : IEditableObject, INotifyPropertyChanged { string _name, _lastName; public string Name { get { return _name; } set { _name = value; _lastName = value + " xxx"; OnPropertyChanged("LastName"); MessageBox.Show("Test"); } } private void OnPropertyChanged(string p) { var x = new PropertyChangedEventArgs(p); if (PropertyChanged != null) PropertyChanged(this, x); } public string LastName { get { return _lastName; } set { _lastName = value; } } public void BeginEdit() { } public void CancelEdit() { } public void EndEdit() { } public event PropertyChangedEventHandler PropertyChanged; } public class myBindingList : BindingList<MyClass> { public myBindingList() { AllowNew = true; Add(new MyClass { Name = "noam" }); Add(new MyClass { Name = "yael" }); } }

  • maintaining a large list in python

    - by Oren
    I need to maintain a large list of python pickleable objects that will quickly execute the following algorithm: The list will have 4 pointers and can: Read\Write each of the 4 pointed nodes Insert new nodes before the pointed nodes Increase a pointer by 1 Pop nodes from the beginning of the list (without overlapping the pointers) Add nodes at the end of the list The list can be very large (300-400 MB), so it shouldnt be contained in the RAM. The nodes are small (100-200 bytes) but can contain various types of data. The most efficient way it can be done, in my opinion, is to implement some paging-mechanism. On the harddrive there will be some database of a linked-list of pages where in every moment up to 5 of them are loaded in the memory. On insertion, if some max-page-size was reached, the page will be splitted to 2 small pages, and on pointer increment, if a pointer is increased beyond its loaded page, the following page will be loaded instead. This is a good solution, but I don't have the time to write it, especially if I want to make it generic and implement all the python-list features. Using a SQL tables is not good either, since I'll need to implement a complex index-key mechanism. I tried ZODB and zc.blist, which implement a BTree based list that can be stored in a ZODB database file, but I don't know how to configure it so the above features will run in reasonable time. I don't need all the multi-threading\transactioning features. No one else will touch the database-file except for my single-thread program. Can anyone explain me how to configure the ZODB\zc.blist so the above features will run fast, or show me a different large-list implementation?

  • CKEditor createFakeParserElement: writeHtml is not a function

    - by Phil Sturgeon
    I am trying to write a plugin for CKEditor that is basically just a iframe with PHP content. The user browses around, selects the video they want and then they click insert. The problem is that I need to create a "fake element" for this video, as inserting a video directly seems to show up as a Flash object, and we need to make it look a little different. I have copied together some code from the Flash plugin.js (remember this is all undocumented and uncommented) and so far come up with this: function insertFakeElement( html ) { editor = window.parent.instance; var realElement = CKEDITOR.dom.element.createFromHtml( html ); var fakeElement = editor.createFakeParserElement( realElement, 'cke_video', 'object', true ), fakeStyle = fakeElement.attributes.style || ''; var width = realElement.attributes.width, height = realElement.attributes.height; if ( typeof width != 'undefined' ) fakeStyle = fakeElement.attributes.style = fakeStyle + 'width:' + cssifyLength( width ) + ';'; if ( typeof height != 'undefined' ) fakeStyle = fakeElement.attributes.style = fakeStyle + 'height:' + cssifyLength( height ) + ';'; editor.insertHTML(fakeElement.getHtml()); } The line "giving me jip" is: var fakeElement = editor.createFakeParserElement( realElement, 'cke_video', 'object', true ), It errors here saying: l.writeHtml is not a function [Break on this error] if(o)o.addRules(l);}});})();a.editor.p..."',o,'_text" The .js file is minified and I have no idea how the source files all fit together so I can't track down the cause of this error. Does anybody know what I am doing wrong?

  • Cocos2D Director Pause/Resume Issue

    - by Aditya
    I am trying to play a .gif animation in cocos2D. For this i am using the library glgif. Now, to display the animation i am pausing the Director, adding a subview to show the animation and after the animation is done i am resuming the Director. However, I am not able to resume the state of the Director and it shows blank. So I tried this without pausing and resuming this Director and it still did not work.I also tried detaching the director before tha animation and adding it back afterwards and even that did not work. So is there a way to pause/suspend the Director in the application and properly restore is back? Thanks. Code sample: [[Director sharedDirector] pause]; [[Director sharedDirector] detach]; AppDelegate *del = [[UIApplication sharedApplication] delegate]; [del.window addSubview:del.viewController.view]; [del.window makeKeyAndVisible]; // this is code to call glgif class and start anim. //code to resume the director AppDelegate *del = [[UIApplication sharedApplication] delegate]; [[Director sharedDirector] resume]; [[Director sharedDirector] attachInView:del.window]; MScene *m = [MScene node]; [[Director sharedDirector] replaceScene:m];

  • Dynamically created "CheckBoxList" in placeholder controls throwing null reference exception error d

    - by newName
    I have a web form that will dynamically create a number of checkboxlist filled with data based on the number of row in database. Then this is added to a placeholder to be displayed. theres a button when clicked, will add the selected check boxes value into database but right now when the button is clicked and after the postback, the page will show the error "System.NullReferenceException". the following code is written in Page_Load in (!Page.IsNotPostBack) and in a loop that will dynamically create a number of checkboxlist: CheckBoxLis chkContent = new CheckBoxList(); chkContent.ID = chkIDString; //chkIDString is an incremental int based on the row count chkContent.RepeatDirection = RepeatDirection.Horizontal; foreach (List<t> contentList in List<t>) //data retrieved as List<t> using LINQ { ListItem contents = new ListItem(); contents.Text = contentList.Title; contents.Value = contentList.contentID.ToString(); chkContent.Items.Add(contents); } plcSchool.Controls.Add(chkContent); //plcSchool is my placeholder plcSchool.Controls.Add(new LiteralControl("<br>")); protected void btnAdd_Click(object sender, EventArgs e) { CheckBoxList cbl = Page.FindControl("chkContent4") as CheckBoxList; Response.Write(cbl.SelectedValue.ToString()); // now im just testing to get the value from one of the checkboxlist } Anyone able to help, as it seems the controls are not recreated after the postback, therefore it can't find the control and throwing the null reference exception.

  • How to select from tableA sum of grouped numbers from tableB above their sums average in Oracle?

    - by Nazgulled
    I have data like this: tableA.ID --------- 1 2 3 tableB.ID tableB.NUM -------------------- 1 10 1 15 2 18 3 12 2 15 3 13 1 12 I need to select tableA IDs where the sum of their NUMs in tableB is above the average of all tableA IDs sums. In other words: SUM ID=1 -> 10+15+12 = 37 SUM ID=2 -> 18+12+15 = 45 SUM ID=3 -> 12+13 = 25 AVG ALL IDs -> (37+45+25)/3 = 35 The SELECT must only show ID 1 and 2 because 37 35, 45 35 but 25 < 35. This is my current query which is working fine: SELECT tableA.ID FROM tableA, tableB WHERE tableA.ID = tableB.ID HAVING SUM(tableB.NUM) > ( SELECT AVG(MY_SUM) FROM ( SELECT SUM(tableB.NUM) MY_SUM FROM tableA, tableB WHERE tableA.ID = tableB.ID GROUP BY tableA.ID ) ) GROUP BY tableA.ID But I have a feeling there might be a better way without all those nested SELECTs. Perhaps 2, but 3 feels like too much. I'm probably wrong though. For instance, why can't I do something simple like this: SELECT tableA.ID FROM tableA, tableB WHERE tableA.ID = tableB.ID HAVING SUM(tableB.NUM) > AVG(SUM(tableB.NUM)) GROUP BY tableA.ID Or this: SELECT tableA.ID, SUM(tableB.NUM) MY_SUM FROM tableA, tableB WHERE tableA.ID = tableB.ID HAVING MY_SUM > AVG(MY_SUM) GROUP BY tableA.ID

  • Python coding test problem for interviews

    - by Kal
    I'm trying to come up with a good coding problem to ask interview candidates to solve with Python. They'll have an hour to work on the problem, with an IDE and access to documentation (we don't care what people have memorized). I'm not looking for a tough algorithmic problem - there are other sections of the interview where we do that kind of thing. The point of this section is to sit and watch them actually write code. So it should be something that makes them use just the data structures which are the everyday tools of the application developer - lists, hashtables (dictionaries in Python), etc, to solve a quasi-realistic task. They shouldn't be blocked completely if they can't think of something really clever. We have a problem which we use for Java coding tests, which involves reading a file and doing a little processing on the contents. It works well with candidates who are familiar with Java (or even C++). But we're running into a number of candidates who just don't know Java or C++ or C# or anything like that, but do know Python or Ruby. Which shouldn't exclude them, but leaves us with a dilemma: On the one hand, we don't learn much from watching someone struggle with the basics of a totally unfamiliar language. On the other hand, the problem we use for Java turns out to be pretty trivial in Python (or Ruby, etc) - anyone halfway competent can do it in 15 minutes. So, I'm trying to come up with something better. Surprisingly, Google doesn't show me anyone doing something like this, unless I'm just too dumb to enter the obvious search term. The best idea I've come up with involves scheduling workers to time slots, but it's maybe a little too open-ended. Have you run into a good example? Or a bad one? Or do you just have an idea?

  • Qt: Force QWebView to click on a web element, even one not visible on the window

    - by Pirate for Profit
    So let's say I'm trying to click a link in the QWebView, here is what I have: // extending QWebView void MyWebView::click(const QString &selectorQuery) { QWebElement el = this->page()->mainFrame()->findFirstElement(selectorQuery); if (!el) return; el.setFocus(); QMouseEvent pressEvent(QMouseEvent::MouseButtonPress, el.geometry().center(), Qt::MouseButton::LeftButton, Qt::LeftButton, Qt::NoModifier); QCoreApplication::sendEvent(this, &pressEvent); QMouseEvent releaseEvent(QMouseEvent::MouseButtonRelease, el.geometry().center(), Qt::MouseButton::LeftButton, Qt::LeftButton, Qt::NoModifier); QCoreApplication::sendEvent(this, &releaseEvent); } And you call it as so: myWebView->click("a[href]"); // will click first link on page myWebView->click("input[type=submit]"); // submits a form THE ONLY PROBLEM IS: if the element is not visible in the window, it is impossible to click. What I mean is if you have to scroll down to see it, you can't click it. I imagine this has to do with the geometry, since the element doesn't show up on the screen it can't do the math to click it right. Any ideas to get around this? Maybe some way to make the window behave like a billion x billion pixels but still look 200x200?

  • Design/Architecture Advice Needed

    - by Rachel
    Summary: I have different components on homepage and each components shows some promotion to the user. I have Cart as one Component and depending upon content of the cart promotion are show. I have to track user online activities and send that information to Omniture for Report Generation. Now my components are loaded asynchronously basically are loaded when AjaxRequest is fired up and so there is not fix pattern or rather information on when components will appear on the webpages. Now in order to pass information to Omniture I need to call track function on $(document).(ready) and append information for each components(7 parameters are required by Omniture for each component). So in the init:config function of each component am calling Omniture and passing paramters but now no. of Omniture calls is directly proportional to no. of Components on the webpage but this is not acceptable as each call to Omniture is very expensive. Now I am looking for a way where in I can club the information about 7 parameters and than make one Call to Omniture wherein I pass those information. Points to note is that I do not know when the components are loaded and so there is no pre-defined time or no. of components that would be loaded. The thing is am calling track function when document is ready but components are loaded after call to Omniture has been made and so my question is Q: How can I collect the information for all the components and than just make one call to Omniture to send those information ? As mentioned, I do not know when the components are loaded as they are done on the Ajax Request. Hope I am able to explain my challenge and would appreciate if some one can provide from Design/Architect Solutions for the Challenge.

  • Django: Complex filter parameters or...?

    - by minder
    This question is connected to my other question but I changed the logic a bit. I have models like this: from django.contrib.auth.models import Group class Category(models.Model): (...) editors = ForeignKey(Group) class Entry(models.Model): (...) category = ForeignKey(Category) Now let's say User logs into admin panel and wants to change an Entry. How do I limit the list of Entries only to those, he has the right to edit? I mean: How can I list only those Entries which are assigned to a Category that in its "editors" field has one of the groups the User belongs to? What if User belongs to several groups? I still need to show all relevant Entries. I tried experimenting with changelist_view() and queryset() methods but this problem is a bit too complex for me. I'm also wondering if granular-permissions could help me with the task, but for now I have no clue. I came up only with this: First I get the list of all Groups the User belongs to. Then for each Group I get all connected Categories and then for each Category I get all Entries that belong to these Categories. Unfortunately I have no idea how to stitch everything together as filter() parameters to produce a nice single QuerySet.
