• .live event doesnt work till second click

  - by ChampionChris

  I have 2 list on a page that are linked. When I drag a li element from list 1 to list 2 the live events on list 1 don't work on the first click only second click. Below is the code that adds the li (obj) to list 2. function AddToDropBox(obj) { $(obj).children(".handle").animate({ width: "20px" }).children("strong").fadeOut(); $(obj).children("span:not(.track,.play,.handle,:has(.btn-edit))").fadeOut('fast'); $(obj).children(".play").css("margin-right", "8px"); $(obj).css({ "opacity": "0.0", "width": "284px" }).animate({ opacity: "1.0" }); if ($(".sidebar-drop-box ul").children(".admin-song").length > 0) { $(".dropTitle").fadeOut("fast"); $(".sidebar-drop-box ul.admin-song-list").css("min-height", "0"); } if (typeof SetLinks == 'function') { SetLinks(); } //CBG Changes adds media ID to hidden field //checks id there is a value in field then adds comma if(document.getElementById("ctl00_cphBody_hfRemoveMedia").value==""||document.getElementById("ctl00_cphBody_hfRemoveMedia").value==null) { document.getElementById("ctl00_cphBody_hfRemoveMedia").value=(obj).attr("mediaid"); } else { var localMediaIDs=document.getElementById("ctl00_cphBody_hfRemoveMedia").value; document.getElementById("ctl00_cphBody_hfRemoveMedia").value=localMediaIDs+", "+(obj).attr("mediaid"); } // alert("hfid: "+document.getElementById("ctl00_cphBody_hfRemoveMedia").value); //END CBG Modifications } this is one of the live() events that dont fire until the second click after the drag. This live() event is in a document.ready function(). // Live for deleting. $(".btn-del").live("click", function(e) { DeleteItem(this); $(this).removeClass("btn-del").addClass("btn-add").parents("li").removeClass("alt").addClass("removed"); var oldTxt = $(this).parents("li").find(".status").text(); $(this).parents("li").find(".status").text("Removed").attr("oldstat", oldTxt); $("#timeHolder input[type=hidden]").val(($("#timeHolder input[type=hidden]").val() * 1) - ($(this).parents("li").find(".time").attr("length") * 1)); CalculateAggregates(); isDirty = false; }); EDIT @dreaton.. Im new to jquery and javascript so thanks for the last tip... Im not sure what you mean about cache the query's. ... the delegete feature is giving me this Microsoft JScript runtime error: Object doesn't support this property or method this is the way I have the code $('#ulPlaylist').delegate('.btn-del', 'click', function (e) { DeleteItem(this); $(this).removeClass("btn-del").addClass("btn-add").parents("li").removeClass("alt").addClass("removed"); var oldTxt = $(this).parents("li").find(".status").text(); $(this).parents("li").find(".status").text("Removed").attr("oldstat", oldTxt); $("#timeHolder input[type=hidden]").val(($("#timeHolder input[type=hidden]").val() * 1) - ($(this).parents("li").find(".time").attr("length") * 1)); CalculateAggregates(); isDirty = false; });

• How to download file into string with progress callback?

  - by Kaminari

  I would like to use the WebClient (or there is another better option?) but there is a problem. I understand that opening up the stream takes some time and this can not be avoided. However, reading it takes a strangely much more amount of time compared to read it entirely immediately. Is there a best way to do this? I mean two ways, to string and to file. Progress is my own delegate and it's working good. FIFTH UPDATE: Finally, I managed to do it. In the meantime I checked out some solutions what made me realize that the problem lies elsewhere. I've tested custom WebResponse and WebRequest objects, library libCURL.NET and even Sockets. The difference in time was gzip compression. Compressed stream lenght was simply half the normal stream lenght and thus download time was less than 3 seconds with the browser. I put some code if someone will want to know how i solved this: (some headers are not needed) public static string DownloadString(string URL) { WebClient client = new WebClient(); client.Headers["User-Agent"] = "Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/532.5 (KHTML, like Gecko) Chrome/4.1.249.1045 Safari/532.5"; client.Headers["Accept"] = "application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5"; client.Headers["Accept-Encoding"] = "gzip,deflate,sdch"; client.Headers["Accept-Charset"] = "ISO-8859-2,utf-8;q=0.7,*;q=0.3"; Stream inputStream = client.OpenRead(new Uri(URL)); MemoryStream memoryStream = new MemoryStream(); const int size = 32 * 4096; byte[] buffer = new byte[size]; if (client.ResponseHeaders["Content-Encoding"] == "gzip") { inputStream = new GZipStream(inputStream, CompressionMode.Decompress); } int count = 0; do { count = inputStream.Read(buffer, 0, size); if (count > 0) { memoryStream.Write(buffer, 0, count); } } while (count > 0); string result = Encoding.Default.GetString(memoryStream.ToArray()); memoryStream.Close(); inputStream.Close(); return result; } I think that asyncro functions will be almost the same. But i will simply use another thread to fire this function. I dont need percise progress indication.

• Extending AdapterView

  - by Ander Webbs

  Hi, i'm trying to make (for learning purposes) my own implementation of a simple AdapterView where items comes from an basic Adapter (ImageAdapter from sdk samples). Actual code is like this: public class MyAdapterView extends AdapterView<ImageAdapter> implements AdapterView.OnItemClickListener{ private ImageAdapter mAdapter; public MyAdapterView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); initThings(); } private void initThings(){ setOnItemClickListener(this); } @Override public ImageAdapter getAdapter() { // TODO Auto-generated method stub return mAdapter; } @Override public void setAdapter(ImageAdapter adapter) { // TODO Auto-generated method stub mAdapter=adapter; requestLayout(); } View obtainView(int position) { View child = mAdapter.getView(position, null, this); return child; } @Override protected void onLayout(boolean changed, int l, int t, int r, int b) { super.onLayout(changed, l, t, r, b); for(int i=0;i<mAdapter.getCount();i++){ View child = obtainView(i); child.layout(10, 70*i, 70, 70); addViewInLayout(child, i, null, true); } this.invalidate(); } @Override public void onItemClick(AdapterView<?> parent, View v, int position, long id) { Log.d("MYEXAMPLES","Clicked an item!"); } } This isn't a coding masterpiece, it just displays a pseudo-listview with pictures. I know i could've used ListView, GridView, Spinner, etc. but i'm relative new to android and i'm trying to figure out some things on it. Well, the question here is: Why is my onItemClick not firing? Using the same ImageAdapter with a GridView, everything works ok, but when i use with above class, i get nothing. Inside AdapterView.java there is code for those click, longclick, etc events... so why can't i just fire them? Maybe i'm misunderstanding basic things on how AdapterView works? Should I extend other base classes instead? And why? Hoping to find more experienced guidance on here, thanks in advance.

• asp:Button is not calling server-side function

  - by Richard Neil Ilagan

  Hi guys, I know that there has been much discussion here about this topic, but none of the threads I got across helped me solve this problem. I'm hoping that mine is somewhat unique, and may actually merit a different solution. I'm instantiating an asp:Button inside a data-bound asp:GridView through template fields. Some of the buttons are supposed to call a server-side function, but for some weird reason, it doesn't. All the buttons do when you click them is fire a postback to the current page, doing nothing, effectively just reloading the page. Below is a fragment of the code: <asp:GridView ID="gv" runat="server" AutoGenerateColumns="false" CssClass="l2 submissions" ShowHeader="false"> <Columns> <asp:TemplateField> <ItemTemplate><asp:Panel ID="swatchpanel" CssClass='<%# Bind("status") %>' runat="server"></asp:Panel></ItemTemplate> <ItemStyle Width="50px" CssClass="sw" /> </asp:TemplateField> <asp:BoundField DataField="description" ReadOnly="true"> </asp:BoundField> <asp:BoundField DataField="owner" ReadOnly="true"> <ItemStyle Font-Italic="true" /> </asp:BoundField> <asp:BoundField DataField="last-modified" ReadOnly="true"> <ItemStyle Width="100px" /> </asp:BoundField> <asp:TemplateField> <ItemTemplate> <asp:Button ID="viewBtn" cssclass='<%# Bind("sid") %>' runat="server" Text="View" OnClick="viewBtnClick" /> </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> The viewBtn above should call the viewBtnClick() function on server-side. I do have that function defined, along with a proper signature (object,EventArgs). One thing that may be of note is that this code is actually inside an ASCX, which is loaded in another ASCX, finally loaded into an ASPX. Any help or insight into the matter will be SO appreciated. Thanks! (oh, and please don't mind my trashy HTML/CSS semantics - this is still in a very,very early stage :p)

• Is there any way to add a MouseListener to a Graphic object ?

  - by Fahad

  Hi, Is there any way to add a MouseListener to a Graphic object. I have this simple GUI that draw an oval. What I want is handling the event when the user clicks on the oval import java.awt.*; import java.awt.event.MouseEvent; import java.awt.event.MouseListener; import javax.swing.*; public class Gui2 extends JFrame { JFrame frame = new JFrame(); MyDrawPanel drawpanel = new MyDrawPanel(); public static void main(String[] args) { Gui2 gui = new Gui2(); gui.go(); } public void go() { frame.getContentPane().add(drawpanel); // frame.addMouseListener(this); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(300, 300); frame.setVisible(true); } } class MyDrawPanel extends JComponent implements MouseListener { public void paintComponent(Graphics g) { int red = (int) (Math.random() * 255); int green = (int) (Math.random() * 255); int blue = (int) (Math.random() * 255); Color startrandomColor = new Color(red, green, blue); red = (int) (Math.random() * 255); green = (int) (Math.random() * 255); blue = (int) (Math.random() * 255); Color endrandomColor = new Color(red, green, blue); Graphics2D g2d = (Graphics2D) g; this.addMouseListener(this); GradientPaint gradient = new GradientPaint(70, 70, startrandomColor, 150, 150, endrandomColor); g2d.setPaint(gradient); g2d.fillOval(70, 70, 100, 100); } @Override public void mouseClicked(MouseEvent e) { if ((e.getButton() == 1) && (e.getX() >= 70 && e.getX() <= 170 && e.getY() >= 70 && e .getY() <= 170)) { this.repaint(); // JOptionPane.showMessageDialog(null,e.getX()+ "\n" + e.getY()); } } @Override public void mouseEntered(MouseEvent e) { // TODO Auto-generated method stub } @Override public void mouseExited(MouseEvent e) { // TODO Auto-generated method stub } @Override public void mousePressed(MouseEvent e) { // TODO Auto-generated method stub } @Override public void mouseReleased(MouseEvent e) { // TODO Auto-generated method stub } } This Works Except it fires when the click is within a virtual box around the oval. Could anyone help me to have it fire when the click is EXACTLY on the oval. Thanks in advance.

• Can sorting Japanese kanji words be done programatically?

  - by Mason

  I've recently discovered, to my astonishment (having never really thought about it before), machine-sorting Japanese proper nouns is apparently not possible. I work on an application that must allow the user to select a hospital from a 3-menu interface. The first menu is Prefecture, the second is City Name, and the third is Hospital. Each menu should be sorted, as you might expect, so the user can find what they want in the menu. Let me outline what I have found, as preamble to my question: The expected sort order for Japanese words is based on their pronunciation. Kanji do not have an inherent order (there are tens of thousands of Kanji in use), but the Japanese phonetic syllabaries do have an order: ???????????????????... and on for the fifty traditional distinct sounds (a few of which are obsolete in modern Japanese). This sort order is called ???? (gojuu on jun , or '50-sound order'). Therefore, Kanji words should be sorted in the same order as they would be if they were written in hiragana. (You can represent any kanji word in phonetic hiragana in Japanese.) The kicker: there is no canonical way to determine the pronunciation of a given word written in kanji. You never know. Some kanji have ten or more different pronunciations, depending on the word. Many common words are in the dictionary, and I could probably hack together a way to look them up from one of the free dictionary databases, but proper nouns (e.g. hospital names) are not in the dictionary. So, in my application, I have a list of every prefecture, city, and hospital in Japan. In order to sort these lists, which is a requirement, I need a matching list of each of these names in phonetic form (kana). I can't come up with anything other than paying somebody fluent in Japanese (I'm only so-so) to manually transcribe them. Before I do so though: Is it possible that I am totally high on fire, and there actually is some way to do this sorting without creating my own mappings of kanji words to phonetic readings, that I have somehow overlooked? Is there a publicly available mapping of prefecture/city names, from the government or something? That would reduce the manual mapping I'd need to do to only hospital names. Does anybody have any other advice on how to approach this problem? Any programming language is fine--I'm working with Ruby on Rails but I would be delighted if I could just write a program that would take the kanji input (say 40,000 proper nouns) and then output the phonetic representations as data that I could import into my Rails app. ??????????

• Tab Bar and Nav Controller: Where did I go wrong in my Interface Builder wiring?

  - by editor

  Even if you don't know how I've shot myself in the foot, a story which I've tried to lay out below, if you think I've done a good job showing the parameters of my problem I'd appreciate an upvote so that I might be able to grab some attention for my question. I've been working on an iPhone application in XCode and Interface Builder of the Tab Bar project type. After getting a table view of topics (business sectors) working fine I realized that I would need to add a Navigation Control to allow the user to drill into a subtopics (subsectors) table. As a green Objective-C developer, that was confusing, but I managed to get it working by reading various documentation trying out a few different IB options. My current setup is a Tab Bar Controller with Tab 1 as a Navigation Controller and Tab 2 a plain view with a Table View placed into it. The wiring works: I can log when table rows are selected and I'm ready to push a new View Controller onto the stack so that I can display the subtopics Table View. My problem: For some reason the first tab's Table View is a delegate and dataSource of the second ta. It doesn't make sense to me and I can't figure out why that's the only setup that works. Here is the wiring: Navigation Controller (Sectors) is a delegate of Tab Bar Navigation Bar is a delegate of Navigation Controller (Sectors) View Contoller (Sectors) has a view of Table View Table View (in Navigation Controller (Sectors)) is a delegate of First View Controller (Companies) Table View (in Navigation Controller (Sectors)) is a dataSource outlet of First View Controller (Companies) First View Controller (Companies) First View Contoller (Sectors) has a view of Table View Table View (in First View Controller (Companies)) is not hooked up to a dataSource outlet and is not a delegate When I click the tab buttons and look at the Inspector I see that the first tab is correctly hooked up to my MainWindow.xib and the second tab has selected a nib called SecondView.xib. It's in the File's Owner of MainWindow.xib where I inherit UITableViewDataSource and UITableViewDelegate (and also UITabBarControllerDelegate) in the .h, and in the .m where I implement the delegate methods. Why does this setup only work when the Table View in my first tab (View Controller (Sectors)) is a delegate and dataSource of the second tab? I'm confused: why wouldn't it need to be hooked up to the Navigation Controller-enabled tab in which the Table View is seen (Navigation Controller (Sectors))? The Table View seen on the second tab has neither dataSource and is not a delegate. I'm having trouble getting a pushViewController to fire (self.navigationController is not nil but the new View Controller still doesn't load) and I suspect that I need to work out this IB wiring issue before I can troubleshoot why the Nav Controller won't push a new View Controller onto the stack. if(nil == self.navigationController) { NSLog(@"self.navigationController is nil."); } else { NSLog(@"self.navigationController is not nil."); SectorList *subsectorViewController = [[SectorList alloc] initWithNibName:@"SectorList" bundle:nil]; subsectorViewController.title = @"Subsectors"; [[self navigationController] pushViewController:subsectorViewController animated:YES]; [subsectorViewController release]; }

• Dynamically loaded jQuery with GreaseMonkey inconsistent on pages (refreshing seems to fix it)... do

  - by uprightnetizen

  Hi, I want a custom page analysis footer on every site I visit... so I've used a method to attach JQuery to unsafeWindow. I then create a floating footer on the page. I want to be able to call commands in a menu, do some processing, then put the results in the footer. Unfortunately it sometimes works, sometimes it doesn't. At least two alerts should happen in the printOutput function. Sometimes it only fires one, then it (crashes?) without error? On other pages, both alerts fire and it finds the element, but it doesn't add the extra text. (e.g. www.linode.com) Refreshing the page, then running the printOutput command again seems to always work. Does anyone know what's going on??? The userscript can be installed at: http://www.captionwizard.com/test/page_analysis.user.js // ==UserScript== // @name page_analysis // @namespace markspace // @description Page Analysis // @include http://*/* // ==/UserScript== (function() { // Add jQuery var GM_JQ = document.createElement('script'); GM_JQ.src = 'http://code.jquery.com/jquery-1.4.2.min.js'; GM_JQ.type = 'text/javascript'; document.getElementsByTagName('head')[0].appendChild(GM_JQ); var jqueryActive = false; //Check if jQuery's loaded function GM_wait() { if(typeof unsafeWindow.jQuery == 'undefined') { window.setTimeout(GM_wait,100); } else { $ = unsafeWindow.jQuery; letsJQuery(); } } GM_wait(); function letsJQuery() { jqueryActive = true; setupOutputFooter(); } /******************************* Analysis FOOTER Functions ******************************/ function printOutput(someText) { alert('printing output'); if($('div.analysis_footer').length) { alert('is here - appending'); $('div.analysis_footer').append('<br>' + someText); } else { alert('not here - trying again'); setupOutputFooter(); $('div.analysis_footer').append('<br>' + someText); } } GM_registerMenuCommand("Test Output", testOutput, "k", "control", "k" ); function testOutput() { printOutput('testing this'); } function setupOutputFooter() { $('<div class="analysis_footer">Page Analysis Footer:</div>').appendTo('body'); $('div.analysis_footer').css('position','fixed').css('bottom', '0px').css('background-color','#F8F8F8'); $('div.analysis_footer').css('width','100%').css('color','#3B3B3B').css('font-size', '0.8em'); $('div.analysis_footer').css('font-family', '"Myriad",Verdana,Arial,Helvetica,sans-serif').css('padding', '5px'); $('div.analysis_footer').css('border-top', '1px solid black').css('text-align', 'left'); } }());

• Sync services not actually syncing

  - by Paul Mrozowski

  I'm attempting to sync a SQL Server CE 3.5 database with a SQL Server 2008 database using MS Sync Services. I am using VS 2008. I created a Local Database Cache, connected it with SQL Server 2008 and picked the tables I wanted to sync. I selected SQL Server Tracking. It modified the database for change tracking and created a local copy (SDF) of the data. I need two way syncing so I created a partial class for the sync agent and added code into the OnInitialized() to set the SyncDirection for the tables to Bidirectional. I've walked through with the debugger and this code runs. Then I created another partial class for cache server sync provider and added an event handler into the OnInitialized() to hook into the ApplyChangeFailed event. This code also works OK - my code runs when there is a conflict. Finally, I manually made some changes to the server data to test syncing. I use this code to fire off a sync: var agent = new FSEMobileCacheSyncAgent(); var syncStats = agent.Synchronize(); syncStats seems to show the count of the # of changes I made on the server and shows that they were applied. However, when I open the local SDF file none of the changes are there. I basically followed the instructions I found here: http://msdn.microsoft.com/en-us/library/cc761546%28SQL.105%29.aspx and here: http://keithelder.net/blog/archive/2007/09/23/Sync-Services-for-SQL-Server-Compact-Edition-3.5-in-Visual.aspx It seems like this should "just work" at this point, but the changes made on the server aren't in the local SDF file. I guess I'm missing something but I'm just not seeing it right now. I thought this might be because I appeared to be using version 1 of Sync Services so I removed the references to Microsoft.Synchronization.* assemblies, installed the Sync framework 2.0 and added the new version of the assemblies to the project. That hasn't made any difference. Ideas? Edit: I wanted to enable tracing to see if I could track this down but the only way to do that is through a WinForms app since it requires entries in the app.config file (my original project was a class library). I created a WinForms project and recreated everything and suddenly everything is working. So apparently this requires a WinForm project for some reason? This isn't really how I planned on using this - I had hoped to kick off syncing through another non-.NET application and provide the UI there so the experience was a bit more seemless to the end user. If I can't do that, that's OK, but I'd really like to know if/how to make this work as a class library project instead.

• Issue with blocking the UI during a onchange request - prevents other event from firing.

  - by jfrobishow

  I am having issues with jQuery blockUI plugins and firing two events that are (I think, unless I am loosing it) unrelated. Basically I have textboxes with onchange events bound to them. The event is responsible for blocking the UI, doing the ajax call and on success unblocking the UI. The ajax is saving the text in memory. The other control is a button with on onclick event which also block the UI, fire an ajax request saving what's in memory to the database and on success unblock the UI. Both of these work fine separately. The issue arise when I trigger the onchange by clicking on the button. Then only the onchange is fired and the onclick is ignored. I can change the text in the checkbox, click on the link and IF jQuery.blockUI() is present the onchange alone is fired and the save is never called. If I remove the blockUI both function are called. Here's a fully working example where you can see the issue. Please note the setTimeout are there when I was trying to simulate the ajax delay but the issue is happening without it. <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script src="http://github.com/malsup/blockui/raw/master/jquery.blockUI.js?v2.31"></script> <script> function doSomething(){ $.blockUI(); alert("doing something"); //setTimeout(function(){ $.unblockUI(); //},500); } function save(){ $.blockUI(); //setTimeout(function(){ alert("saving"); $.unblockUI(); //}, 1000); } </script> </head> <body> <input type="text" onchange="doSomething();"> <a href="#" onclick="save()">save</a> </body> </html>

• Force deletion of slot in boost::signals2

  - by villintehaspam

  Hi! I have found that boost::signals2 uses sort of a lazy deletion of connected slots, which makes it difficult to use connections as something that manages lifetimes of objects. I am looking for a way to force slots to be deleted directly when disconnected. Any ideas on how to work around the problem by designing my code differently are also appreciated! This is my scenario: I have a Command class responsible for doing something that takes time asynchronously, looking something like this (simplified): class ActualWorker { public: boost::signals2<void ()> OnWorkComplete; }; class Command : boost::enable_shared_from_this<Command> { public: ... void Execute() { m_WorkerConnection = m_MyWorker.OnWorkDone.connect(boost::bind(&Command::Handle_OnWorkComplete, shared_from_this()); // launch asynchronous work here and return } boost::signals2<void ()> OnComplete; private: void Handle_OnWorkComplete() { // get a shared_ptr to ourselves to make sure that we live through // this function but don't keep ourselves alive if an exception occurs. shared_ptr<Command> me = shared_from_this(); // Disconnect from the signal, ideally deleting the slot object m_WorkerConnection.disconnect(); OnComplete(); // the shared_ptr now goes out of scope, ideally deleting this } ActualWorker m_MyWorker; boost::signals2::connection m_WorkerConnection; }; The class is invoked about like this: ... boost::shared_ptr<Command> cmd(new Command); cmd->OnComplete.connect( foo ); cmd->Execute(); // now go do something else, forget all about the cmd variable etcetera. the Command class keeps itself alive by getting a shared_ptr to itself which is bound to the ActualWorker signal using boost::bind. When the worker completes, the handler in Command is invoked. Now, since I would like the Command object to be destroyed, I disconnect from the signal as can be seen in the code above. The problem is that the actual slot object is not deleted when disconnected, it is only marked as invalid and then deleted at a later time. This in turn appears to depend on the signal to fire again, which it doesn't do in my case, leading to the slot never expiring. The boost::bind object thus never goes out of scope, holding a shared_ptr to my object that will never get deleted. I can work around this by binding using the this pointer instead of a shared_ptr and then keeping my object alive using a member shared_ptr which I then release in the handler function, but it kind of makes the design feel a bit overcomplicated. Is there a way to force signals2 to delete the slot when disconnecting? Or is there something else I could do to simplify the design? Any comments are appreciated!

• Programmatically triggering events in Javascript for IE using jQuery

  - by Dan Herbert

  When an Event is triggered by a user in IE, it is set to the window.event object. The only way to see what triggered the event is by accessing the window.event object (as far as I know) This causes a problem in ASP.NET validators if an event is triggered programmatically, like when triggering an event through jQuery. In this case, the window.event object stores the last user-triggered event. When the onchange event is fired programmatically for a text box that has an ASP.NET validator attached to it, the validation breaks because it is looking at the element that fired last event, which is not the element the validator is for. Does anyone know a way around this? It seems like a problem that is solvable, but from looking online, most people just find ways to ignore the problem instead of solving it. To explain what I'm doing specifically: I'm using a jQuery time picker plugin on a text box that also has 2 ASP.NET validators associated with it. When the time is changed, I'm using an update panel to post back to the server to do some things dynamically, so I need the onchange event to fire in order to trigger the postback for that text box. The jQuery time picker operates by creating a hidden unordered list that is made visible when the text box is clicked. When one of the list items is clicked, the "change" event is fired programmatically for the text box through jQuery's change() method. Because the trigger for the event was a list item, IE sees the list item as the source of the event, not the text box, like it should. I'm not too concerned with this ASP.NET validator working as soon as the text box is changed, I just need the "change" event to be processed so my postback event is called for the text box. The problem is that the validator throws an exception in IE which stops any event from being triggered. Firefox (and I assume other browsers) don't have this issue. Only IE due to the different event model. Has anyone encountered this and seen how to fix it? I've found this problem reported several other places, but they offer no solutions: jQuery's forum, with the jQuery UI Datepicker and an ASP.NET Validator ASP.NET forums, bug with ValidatorOnChange() function

• 'Timeout Expired' error against local SQL Express on only 2 LINQ Methods...

  - by Refracted Paladin

  I am going to sum up my problem first and then offer massive details and what I have already tried. Summary: I have an internal winform app that uses Linq 2 Sql to connect to a local SQL Express database. Each user has there own DB and the DB stay in sync through Merge Replication with a Central DB. All DB's are SQL 2005(sp2or3). We have been using this app for over 5 months now but recently our users are getting a Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. Detailed: The strange part is they get that in two differnt locations(2 differnt LINQ Methods) and only the first time they fire in a given time period(~5mins). One LINQ method is pulling all records that match a FK ID and then Manipulating them to form a Heirarchy View for a TreeView. The second is pulling all records that match a FK ID and dumping them into a DataGridView. The only things I can find in common with the 2 are that the first IS an IEnumerable and the second converts itself from IQueryable - IEnumerable - DataTable... I looked at the query's in Profiler and they 'seemed' normal. They are not very complicated querys. They are only pulling back 10 - 90 records, from one table. Any thoughts, suggestions, hints whatever would be greatly appreciated. I am at my wit's end on this.... public IList<CaseNoteTreeItem> GetTreeViewDataAsList(int personID) { var myContext = MatrixDataContext.Create(); var caseNotesTree = from cn in myContext.tblCaseNotes where cn.PersonID == personID orderby cn.ContactDate descending, cn.InsertDate descending select new CaseNoteTreeItem { CaseNoteID = cn.CaseNoteID, NoteContactDate = Convert.ToDateTime(cn.ContactDate). ToShortDateString(), ParentNoteID = cn.ParentNote, InsertUser = cn.InsertUser, ContactDetailsPreview = cn.ContactDetails.Substring(0, 75) }; return caseNotesTree.ToList<CaseNoteTreeItem>(); } AND THIS ONE public static DataTable GetAllCNotes(int personID) { using (var context = MatrixDataContext.Create()) { var caseNotes = from cn in context.tblCaseNotes where cn.PersonID == personID orderby cn.ContactDate select new { cn.ContactDate, cn.ContactDetails, cn.TimeSpentUnits, cn.IsCaseLog, cn.IsPreEnrollment, cn.PresentAtContact, cn.InsertDate, cn.InsertUser, cn.CaseNoteID, cn.ParentNote }; return caseNotes.ToList().CopyLinqToDataTable(); } }

• Phonegap (Cordova) iOS button click

  - by JNM

  I am trying to create a very simple phone gap application for iOS. I am using query mobile. the problem is, that i can't get javascript event to fire on button click. Code i have now: <!DOCTYPE html> <html> <head> <title>Title</title> <meta name="viewport" content="width=device-width, minimum-scale=1, maximum-scale=1"> <meta charset="utf-8"> <link rel="stylesheet" type="text/css" href="js/jquery.mobile-1.2.0.css" /> <script type="text/javascript" charset="utf-8" src="cordova-1.8.1.js"></script> <script type="text/javascript" charset="utf-8" src="js/jquery-1.8.2.min.js"></script> <script type="text/javascript" charset="utf-8" src="js/jquery.mobile-1.2.0.min.js"></script> <script type="text/javascript"> document.addEventListener("deviceready", onDeviceReady, false); function onDeviceReady() { } function showAlert() { navigator.notification.alert("Cordova is working"); } </script> </head> <body> <div data-role="page" id="options" data-add-back-btn="true" data-back-btn-text="Atgal"> <div data-role="header" data-position="fixed"> <h1>Title</h1> </div> <div data-role="content"> <h1>Alert</h1> <p><a href="#" onclick="showAlert(); return false;" data-role="button">Show alert</a></p> </div> </div> </body> </html> I tried multiple solutions to fix my problem, but none of them works. When have button with # in href, it doesn't event change the color on click. When i add url, it changes color. But it never call javascript function. Another problem is, that document.addEventListener("deviceready", onDeviceReady, false); works only in the index page. If i press button in initial page which redirects to another page, OnDeviceReady function is never called. Anybody has any ideas?

• Please help with very simple android widget button click. Getting very frustrated. :(

  - by Little Wendy

  I have poured over every example that I can find and I have gone through the official documentation from google. All I am trying to do is create a toast notification from a button click on a widget. I can get the widget (and button) to appear but I can't get my intent to fire. I have seen several examples that show doing this different ways but I just can't get it to work. I haven't felt this helpless with coding in a long time and I'm starting to feel dumb. This is what I have so far: public class simpleclick extends AppWidgetProvider { /** Called when the activity is first created. */ @Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { final int N = appWidgetIds.length; Toast.makeText(context, "doing on update", Toast.LENGTH_SHORT).show(); for (int i=0; i<N; i++) { int appWidgetId = appWidgetIds[i]; Intent intent = new Intent(context, simpleclick.class); intent.setAction("ham"); PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0); RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.main); views.setOnClickPendingIntent(R.id.Timm, pendingIntent); appWidgetManager.updateAppWidget(appWidgetId, views); } } //@Override public void onReceive(Context context, Intent intent) { // TODO Auto-generated method stub Toast.makeText(context, "action is: " + intent.getAction(), Toast.LENGTH_SHORT).show(); super.onReceive(context, intent); } } My manifest: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.tblabs.simpleclick" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <receiver android:name="simpleclick"> <intent-filter> <action android:name="android.appwidget.action.APPWIDGET_UPDATE" /> </intent-filter> <meta-data android:name="android.appwidget.provider" android:resource="@xml/simpleclick" /> </receiver> </application> <uses-sdk android:minSdkVersion="5" /> </manifest> I would appreciate some help!

• Can't get jQuery to get focus on cloned input fields

  - by Rebel1Moon

  I have a page that needs to create dynamic form fields as often as the user needs, and I am trying to use Ajax to tie it in to my database for faster form entry and to prevent user typos. So, I have put my Ajax returned data into popup div, the user selects, then the form field is filled in. The problem comes on the cloned fields. They don't seem to want to bring up the popup div when focused. I am thinking it is something to do with when they get created/added to the DOM. Here is my JS that creates the clones: $(document).ready(function() { var regex = /^(.*)(\d)+$/i; var cloneIndex = $(".clonedInput").length; $("button.clone").live("click", function(){ $(this).parents(".clonedInput").clone() .appendTo("#course_container") .attr("id", "clonedInput" + cloneIndex) .find("*").each(function() { var id = this.id || ""; var match = id.match(regex) || []; if (match.length == 3) { this.id = match[1] + (cloneIndex); } }); cloneIndex++; numClones=cloneIndex-1; //alert("numClones "+numClones); }); Here is where I expect to be able to get focus on the correct cloned field and call the popup. The baker_equiv0 id is original code, whereas baker_equiv1 is the first clone. $('#baker_equiv0').focus(function() { \\ THIS CODE WORKS $('.popup').fadeIn(500); $('#results').empty(); // document.enter_data.baker_equiv1.value="test"; THIS LINE WORKS //alert("numClones "+numClones); }); $('#baker_equiv1').focus(function() { // THIS DOESN'T EVER FIRE alert("numClones "+numClones); $('.popup').fadeIn(500); $('#results').empty(); }); Here is the HTML with the form: <label for="baker_equiv" class="">Baker Equivalent: <span class="requiredField">*</span></label> <input type="text" class="cinputsa" name="baker_equiv[]" id="baker_equiv0" size="8" ONKEYUP="get_equiv(this.value);"> If I put this in the HTML code above, it works fine: onfocus="alert(this.id)" I'd also be interested in how to adjust the JS code to work based on the id array created rather than having to copy code for each potential set of fields clones, i.e., baker_equiv[] rather than baker_equiv0, baker_equiv1, etc. Thanks all!

• Freemarker rendering differently on IE8

  - by scphantm

  we have a template that uses this for the record line <input type="${inputType}" name="${variableName}.code" id="${variable}.${vnum}.${answer.code}" class="checkbox" value="${answer.code}" [#nested/] [#if (answer.textLength > 0) && scripting]onchange="showOtherBox( this, '${variable}.[#if descriptionHack]${variableNumber}[#else]${vnum}[/#if].${answer.code}.description' )"[/#if] [#if showValues && (existing == answer.code)]checked="checked"[/#if]/> On IE8 it renders as this <span class="field"> <INPUT id=responses.8.L class=checkbox value=L type=checkbox name="responses['8'].answers['L'].code"> <LABEL for=responses.8.L>Award(s) for special accomplishment or performance related to activity participation (please list)</LABEL> <TEXTAREA id=responses.8.L.description class=" visible" rows=4 cols=60 name="responses['8'].answers['L'].description"></TEXTAREA> </span> and on every other browser we tried, it renders as this <span class="field"> <input type="checkbox" name="responses['8'].answers['L'].code" id="responses.8.L" class="checkbox" value="L" onchange="showOtherBox( this, 'responses.8.L.description' )"> <label for="responses.8.L">Award(s) for special accomplishment or performance related to activity participation (please list)</label> <textarea rows="4" cols="60" name="responses['8'].answers['L'].description" id="responses.8.L.description" class="visible" classname="visible"></textarea> </span> The difference being that in the FTL script, the if statement [#if (answer.textLength > 0) && scripting] is true for everything except IE. In IE8 its false for some reason and therefore it does not put the OnChange javascript event on the input tag. Has anyone seen anything like this before? we are using Freemarker 2.3.9 Update, it kinda works if i turn compatibility mode on for IE8. but not exactly. when i do that, the onchange event doesn't fire until the check box loses focus. which is very different than everything else. Is there a quick way to fix this without too much trouble? i suppose i could put something in that says if ie8, insert onclick instead of onchange. that may work, but i would need an authorization from the client to fix it like that.

• Problems with starting windows service on windows xp SP3

  - by Michiel Peeters

  I'm currently facing a problem which I can not resolve and I really don't know what to do anymore. When I'm trying to start the service I receive the message: "The service is started but again also stopped, this because that some of the services will stop if they have nothing to do, for example the performance logs and the alerts service". I've looked into the Windows Logs but nothing is written there which could describe why my service is all the time stopping. I've also tried to fire the windows service via the command prompt which gives me the message: "The service is not started, but the service didn't return any faults.". I've tried to remove all keys which references to my service, which didn't resolve the issue. I've searched on google (maybe not good enough) to find an answer but I didn't found any. I did found some websites which describes what I could do, but all of these suggestions didn't work. This is kinda ** because I do not know where to look. I do not have any error message, i do not have any id which i can use to search on. I really don't know where to start and I hope you guys can help me on this one. Detailed explanation about the windows service OS: Windows XP SP3 .Net Framework: .Net 4.0 Client Profile Language: C# Development environment: Visual Studio 2010 Professional (but Visual Studio 2012 RC is installed) Communications: WCF (Named Pipes), WCF (BasicHTTPBinding) Named Pipes: I have chosen for this solution because I wanted to communicate from a windows service to a windows form application. It worked now for quite some time but suddenly my windows service shuts it self down and I couldn't restart it anymore. There are two named pipes services implemented: An event service which will send any notification to the windows form application and an management service which gives my windows form application the possibility to maintain my windows service. BasicHTTPBinding: The basic http binding makes the connection to a central server. This connection is then used for streaming information from the client to the server. I do not know which additional information you will need, but if you guys need something then I'll try to give it as detailed as possible. Thank you in advance.

• Cannot get document.getElementById() to find my textarea

  - by Slruh

  Maybe I've been working on my site for to long, but I can't get the following to work. I am having my textarea fire an onkeyup() event called limiter which is supposed to check the textarea and limit the text in the box, while updated another readonly input field that shows the amount of characters left. This is the javascript code: <script type="text/javascript"> var count = "500"; function limiter(){ var comment = document.getElementById("comment"); var form = this.parent; var tex = comment.value; var len = tex.length; if(len > count){ tex = tex.substring(0,count); comment.value =tex; return false; } form.limit.value = count-len; } </script> The form looks like this: <form id="add-course-rating" method="post" action="/course_ratings/add/8/3/5/3" accept- charset="utf-8"><div style="display:none;"><input type="hidden" name="_method" value="POST" /> //Other inputs here <div id="comment-name" style="margin-top:10px"> <div id="comment-name-text"> <b>Comments</b><br /> Please leave any comments that you think will help anyone else. </div> <style type="text/css"> .rating-form-box textarea { -moz-border-radius:5px 5px 5px 5px; } </style> <div class="rating-form-box"> <textarea name="data[CourseRatings][comment]" id="comment" onkeyup="limiter()" cols="115" rows="5" ></textarea> <script type="text/javascript"> document.write("<input type=text name=limit size=4 readonly value="+count+">"); </script> </div> <input type="submit" value="Add Rating" style="float: right;"> </form> If anyone can help that would be great.

• Difficulty with jQuery and input keydown event

  - by Rosarch

  I am making a simple JavaScript enhanced list. I want it to be a list of inputs, each with an 'Add' and 'Remove' button. If the user clicks 'Add', a new li will be added. If the user clicks 'Remove', that li will be removed. It works fine, except for hitting "enter" in an <input>. Currently, it always causes the Remove.click event handler to fire, unless there's only one item in the list. I'm not sure why. How can I suppress this? Here is the complete jQuery. My attempt to fix the "enter" issue is commented out, and it doesn't work. I suspect that I could be designing this code better; if you see an improvement I'd love to hear it. function make_smart_list(list) { var ADD_CLASS = 'foo-widget-Add'; var REMOVE_CLASS = 'foo-widget-Remove'; var jq_list = $(list); jq_list.parents('form').submit(function() { return false; }); function refresh_handlers() { jq_list.find(sprintf('.%s, .%s', REMOVE_CLASS, ADD_CLASS)).unbind('click'); // jq_list.find('input').unbind('submit'); // // jq_list.find('input').submit(function() { // var jq_this = $(this); // var next_button = jq_this.nextAll('button'); // if (next_button.hasClass(ADD_CLASS)) { // next_button.nextAll('button').click(); // return; // } // // if (next_button.hasClass(REMOVE_CLASS)) { // return false; // } // // }); jq_list.find("." + REMOVE_CLASS).click(function() { var jq_this = $(this); jq_this.parent().remove(); refresh_handlers(); return false; }); jq_list.find("." + ADD_CLASS).click(function() { var jq_this = $(this); if (jq_this.prevAll('input').val() == '') { return; } jq_this.parent().clone().appendTo(jq_this.parent().parent()); jq_this.parent().next().find('input').val('').focus(); jq_this.removeClass(ADD_CLASS).addClass(REMOVE_CLASS); jq_this.text('Remove'); refresh_handlers(); return false; }); } refresh_handlers(); } (sprintf is another script I have.)

• eth0 and eth1 both assigned same IP on boot

  - by Banjer

  I have a physical SLES 11 SP2 server on a Sun Fire x4140 that is giving me problems with networking upon reboot. The NICs are onboard. The networking appears successful during boot, but network services such as nfs fail hard. This is because eth0 and eth1 are both receiving the same configuration and are both ifup-ed. Once everything times out and I'm at the console, ifconfig shows that eth0 and eth1 are UP and running with the same IP. Attempting to ping anything in that subnet fails. Restarting the network service fixes the issue. eth0 is the correct NIC that should be configured as primary, per the MAC address. Question: Whats causing eth1 to be brought up with the same config as eth0?? I do not have a config script set up for eth1: banjer@harp:~> ls -la /etc/sysconfig/network/ total 104 drwxr-xr-x 6 root root 4096 Jun 11 12:21 . drwxr-xr-x 6 root root 4096 Apr 10 09:46 .. -rw-r--r-- 1 root root 13916 Apr 10 09:32 config -rw-r--r-- 1 root root 9952 Apr 10 09:36 dhcp -rw------- 1 root root 180 Jun 11 12:21 ifcfg-eth0 -rw------- 1 root root 180 Jun 11 12:21 ifcfg-eth3 -rw------- 1 root root 172 Feb 1 08:32 ifcfg-lo -rw-r--r-- 1 root root 29333 Feb 1 08:32 ifcfg.template drwxr-xr-x 2 root root 4096 Apr 10 09:32 if-down.d -rw-r--r-- 1 root root 239 Feb 1 08:32 ifroute-lo drwxr-xr-x 2 root root 4096 Apr 10 09:33 if-up.d drwx------ 2 root root 4096 May 5 2010 providers -rw-r--r-- 1 root root 25 Nov 16 2010 routes drwxr-xr-x 2 root root 4096 Apr 10 09:36 scripts On a side note, eth3 is also configured with an IP in a different subnet, but this has not posed any problems.

• Troubleshooting PHP email sending?

  - by darkAsPitch

  I created a website that occasionally emails users when they register/change their password/etc. Every other person however cannot or does not receive the emails. They are telling me that they are not even hitting their spam folders. I don't know a ton about MX records or email sending, but when I "Edit DNS Zone" for this domain in particular there is 1 MX record listed there. How do you go about troubleshooting botched PHP mail actions? UPDATE: Here is my super-simple php mailing code: $subject = "Subject Here"; $message = "Emails Message"; $to = $verified_user_data["email_address"]; $headers = "From: [email protected]\r\n" . "Reply-To: [email protected]\r\n" . "X-Mailer: PHP/" . phpversion(); //returns true on success, false on failure $email_result = mail($to, $subject, $message, $headers); re: "are you saying that some do and some do not?" @ Jacob Yes, basically. I send the emails containing the user's login username/password using similar code above. And I sell to fairly tech-savvy people. About 50% of the time, my customers claim they cannot find their welcome emails in their inbox OR in their spam box. It's as if it never arrived. I have the largest problem with Yahoo email addresses accepting my emails or so it seems. re: "The MX record at your end doesn't factor in, although the SPF record (or lack of it) will. How much access and control do you have on the server itself?" @ John Gardeniers I rent a dedicated server from Codero. Running CentOS 5, WHM + cPanel. I have full root access to the entire thing. Don't know much about MX records and/or SPF records. I just want the PHP mail function to work. It doesn't say much about that on the php mail function's help page. re: "What are you using for the SMTP server?" @ JonLim No idea. I use the code above when I need to fire off an email to a loyal customer, and that's it. Do I need to be worrying about SMTP servers? re: "Could be many, many things. Can you describe how you're sending mail in your code? i.e. are you relaying off of another mail server somewhere, using the local sendmail or postfix? Any consistency in domains that can/cannot receive email? Do you have a PTR record setup from the IP address that you're sending mail out as? What about SPF records?" @ gravyface I just described my simple code above! I believe I have been having the most trouble with Yahoo domains, however "independent" domains (probably running spamassasin) ex. [email protected] as opposed to [email protected] seem to give a lot of trouble as well. I do not know if I have a PTR record setup from the IP address I'm sending my mail from. It's probably the same IP address that I setup my domain on, because I didn't do anything extra special. No idea about SPF records either, where can I go to create one? Side Note: It's a crying shame what havoc the spammers have brought upon our beloved email system.

• set proxy in apache for XMPP chat

  - by Hunt

  I want to setup a proxy settings in Apache to use Facebook XMPP Chat So far I have setup ejabber server and I am able to access xmpp service using http://mydomain.com:5280/xmpp-http-bind I am able to create Jabber Account too. Now as I want to integrate Facebook XMPP chat , I want my server to sit in between client and chat.facebook.com because I want to implement Facebook chat and custom chat too. So I have read this article and come to know that I need to serve BOSH Service as a proxy in apache to access Facebook Chat service. So I don't know how to set up a proxy in a apache httpd.conf as I have tried following <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass /xmpp-httpbind http://www.mydomain.com:5280/xmpp-http-bind ProxyPassReverse /xmpp-httpbind http://www.mydomain.com:5280/xmpp-http-bind But whenever I request http://www.mydomain.com:5280/xmpp-http-bind from strophe.js I am getting following response from server <body type='terminate' condition='internal-server-error' xmlns='http://jabber.org/protocol/httpbind'> BOSH module not started </body> and server log says following E(<0.567.0:ejabberd_http_bind:1239) : You are trying to use BOSH (HTTP Bind) in host "chat.facebook.com", but the module mod_http_bind is not started in that host.

• Strange Upload Problem on Hyper-V

  - by Ring0

  Hi, This one is driving me totally nuts. I have being trying to upload a file to www.virustotal.com (its a harmless exe I have since found out - DiskWipe.exe from diskwipe.org). Using IE8. From Win 7 and Win 2008 R2 Datacenter (which I select to boot from vhd's) onto my main machine hardware, and also on another Win 7 PC elsewhere on my network, when I upload the file to virustotal.com it works perfectly. So, using my native NIC's everything is fine. Using another machine also perfect. Right. OK, from my boot menu the default is my main development machine - the one I'm typing on now. This runs on the metal and has Hyper-V role and I have some guests. All guests are not running. Amazingly, from my console (root partition to be exact) or any guest OS 2003 /XP / 2008 R2 etc. My upload to virustotal.com slows at 32% then HANGS at 38.something% & never finishes!! Here is the kicker. I have another box (my main server) running Hyper-V on the metal and three live guests. Identical H/W to my main dev machine in another room. (Except OS is Datacenter - Mine is Enterprise). If I try and upload from its bare metal console or any guest this file to virustotal.com using IE8 it stops exactly in the same place!! As for "steps I have tried etc." are kind-of blown out of the water as my server box is doing the precise same thing as the machine in my room here. OK, comonalities: Mobo: Gigabyte GA-X58-UD5, 12GB Kingston RAM, Corei7 920 4 cores hyperthreading = 8 & Realtek RTL8168D/8111D Family PCI-E Gigabit Ethernet NIC's. All 3 machines have this same motherboard - revision F11 Bios, all have 12GB RAM, all have the Realtek Nic's. All x64 by the way as I mentioned before I have a Win 7 box also with the UD5 m/Board, 12 GB RAM - bit of an overkill. :-) All these machines when NOT running Hyper-V can upload this file. Perhaps you may like to try it on a Hyepr-v (2008 R2) yourselves with IE8 and the desktop experience is on. See if it works or fails for you. Root OS or any guest. So, looking like its the NIC + Hyper-V = Cannot upload this file (any file I must add.) Realtek Nic is Ver 7.002.1125.2008. Using IE8 I see in the nic settings there are the usual parameters for Jumbo frames / Checksum offloading etc. several others. Should I fiddle with these? I ran Netmon 3.3 in a guest and the TCP session halted as the upload failed. I suppose I could study that further. I dont have Netmon on the root partition machine (yet)! All OS's fully patched - including todays defender files. My box running Office 2007 - but identical server in another room is not. Also, if I fire up a VPN to a distant client and do the upload it works! Of course its a different network path. Suggestions welcome please. If I left out anything important - please yell at me. Many Thanks,
