• Google Maps Api v3 - getBounds is undefined

  - by Via Lactea

  Hi All, I'm switching from v2 to v3 google maps api and got a problem with gMap.getBounds() function. I need to get the bounds of my map after its initialization. Here is my javascript code: var gMap; $(document).ready( function() { var latlng = new google.maps.LatLng(55.755327, 37.622166); var myOptions = { zoom: 12, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP }; gMap = new google.maps.Map(document.getElementById("GoogleMapControl"), myOptions); alert(gMap.getBounds()); So now it alerts me that gMap.getBounds() is undefined. I've tryed to get getBounds values in click event and it works fine for me, but I cannot get the same results in load map event. Also getBounds works fine while document is loading in Google Maps API v2, but it fails in V3. Could you please help me to solve this problem?

• jQuery(document).ready doesn't run under IIS7

  - by gsiler

  To simplify this test case, I created a new default .NET MVC project in Visual Studio 2010, and added the following code to the HTML header in Site.Master: <script type="text/javascript" src="../../Scripts/jquery-1.4.1.js"></script> <script type="text/javascript"> jQuery(document).ready(function () { alert('jQuery document ready'); }); </script> This works as expected in the .NET development server. However, when deployed to IIS7, the jQuery(document).ready function is not executed. Needless to say, my actual application is much more complicated. This eliminates all "suspects" except IIS7 deployment. Any thoughts/suggestions?

• Javacript in html - Using single quote inside another single quote

  - by Ashish Nair

  document.getElementById("img").innerHTML="< img src='/sitepath/"+imgg+".jpg' width='72' height='44' onclick='alert('hello');' />"; The above code is my javascript. Problem is printing hello or any other string. If I just type 123 in place of hello, it does give alert. But am not able to use a string like hello there. Normally a string in an alert function is kept inside quotes ' ' but the entire content is inside double quotes and I have already used single quote at the beginning of onclick function. I tried using Escape character ("\") but it didnt help. Any suggestions?

  Is it possible to combine Ajax post with jQuery UI dialog?

• How can I extract similarities/patterns from a collection of binary strings?

  - by JohnIdol

  I have a collection of binary strings of given size encoding effective solutions to a given problem. By looking at them, I can spot obvious similarities and intuitively see patterns of symmetry and periodicity. Are there mathematical/algorithmic tools I can "feed" this set of strings to and get results that might give me an idea of what this set of strings have in common? By doing so I would be able to impose a structure (or at least favor some features over others) on candidate solutions in order to greatly reduce the search space, maximizing chances to find optimal solutions for my problem (I am using genetic algorithms as the search tool - but this is not pivotal to the question). Any pointers/approaches appreciated.

• Can't disable jQuery cache

  - by robert_d

  Update I figured out that it must be caching problem but I can't turn cache off. Here is my changed script: <script src="../../Scripts/jquery-1.4.1.js" type="text/javascript"></script> <script type="text/javascript"> jQuery.ajaxSetup({ // Disable caching of AJAX responses cache: false }); jQuery("#button1").click(function (e) { window.setInterval(refreshResult, 3000); }); function refreshResult() { jQuery("#divResult").load("/Home/Refresh"); } </script> It updates part of a web page every 3 sec. It works only once after clearing web browser cache, after that it doesn't work - requests are made to /Home/Refresh without interval of 3 seconds and nothing is displayed on the web page; subsequent requests send cookie ASP.NET_SessionId=wrkx1avgvzwozcn1frsrb2yh. I am using ASP.NET MVC 2 and c#. I have a problem with jQuery, here is how my web app works Search.aspx web page which contains a form and jQuery script posts data to Search() action in Home controller after user clicks button1 button. Search.aspx: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<GLSChecker.Models.WebGLSQuery>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Title </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Search</h2> <% Html.EnableClientValidation(); %> <% using (Html.BeginForm()) {%> <fieldset> <div class="editor-label"> <%: Html.LabelFor(model => model.Url) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.Url, new { size = "50" } ) %> <%: Html.ValidationMessageFor(model => model.Url) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.Location) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.Location, new { size = "50" } ) %> <%: Html.ValidationMessageFor(model => model.Location) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.KeywordLines) %> </div> <div class="editor-field"> <%: Html.TextAreaFor(model => model.KeywordLines, 10, 60, null)%> <%: Html.ValidationMessageFor(model => model.KeywordLines)%> </div> <p> <input id ="button1" type="submit" value="Search" /> </p> </fieldset> <% } %> <script src="../../Scripts/jquery-1.4.1.js" type="text/javascript"></script> <script type="text/javascript"> jQuery("#button1").click(function (e) { window.setInterval(refreshResult, 5000); }); function refreshResult() { jQuery("#divResult").load("/Home/Refresh"); } </script> <div id="divResult"> </div> </asp:Content> [HttpPost] public ActionResult Search(WebGLSQuery queryToCreate) { if (!ModelState.IsValid) return View("Search"); queryToCreate.Remote_Address = HttpContext.Request.ServerVariables["REMOTE_ADDR"]; Session["Result"] = null; SearchKeywordLines(queryToCreate); Thread.Sleep(15000); return View("Search"); }//Search() After button1 button is clicked the above script from Search.aspx web page runs. Search() action in controller runs for longer period of time. I simulate this in testing by putting Thread.Sleep(15000); in Search()action. 5 sec. after Submit button was pressed, the above jQuery script calls Refresh() action in Home controller. public ActionResult Refresh() { ViewData["Result"] = DateTime.Now; return PartialView(); } Refresh() renders this partial <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" % <%= ViewData["Result"] % The problem is that in Internet Explorer 8 there is only one request to /Home/Refresh; in Firefox 3.6.3 all requests to /Home/Refresh are made but nothing is displayed on the web page. Another problem with Firefox is that requests to /Home/Refresh are made every second not every 5 seconds. I noticed that after I clear Firefox cache the script works well first time button1 is pressed, but after that it doesn't work. I would be grateful for helpful suggestions.

• Java interface to Windows communications? (OLE, OPC, DDE)

  - by Jared

  I need to integrate an off-the-shelf Windows application with a Java application. At a few key points, I need the Windows application to send an "event" and some data to the Java application. The Windows application anticipated this need, and can be configured to "Poke a DDE Item", "Set an OLE Auto-Property" or "Write an OPC Item". I'm already using JACOB to call COM methods and set COM properties on a COM object. However, I'm guessing that's pretty unrelated to these "event" notification capabilities. Anyone have any experience calling FROM a Windows application to a "DDE Item", "OLE Auto-Property" or "OPC Item" that's actually in a JVM? Any pointers, advice, etc, would be appreciated.

• How to create makefile for Lazarus projects?

  - by Gustavo Carreno

  After doing a light search on the Lazarus site I've come to the conclusion that this question has been asked some times but I haven't found an answer, so I'll ask my SO peers. Is there a a way to create a Makefile to replicate the action of the Lazarus IDE when it compiles a project. If so I really don't mind if it's makefile.fpc or just plain makefile, I just want some pointers on how to get to it. BTW, I've tried the option to enable the Makefile on the Lazarus options. Doesn't work.

• How to find (in javascript) the current "scroll" offset in mobile safari / iphone

  - by mintywalker

  I'd like to know the x/y offset of the how far the user has "scrolled" within the viewport in mobile safari on the iphone. Put another way, if I (through javascript) reloaded the current page, I'd like to find the values I'd need to pass into window.scrollTo(...) in order to reposition the document/viewport as it is currently. window.pageXOffset always reports 0 jquery's $('body').scrollTop() always reports 0 events have a pageX, but this won't account for the scrolling of the page that happens after you release your finger if your gesture was to "flick" the page up/down. Namely, it'll give me a point when the finger leaves the screen, but that doesn't always match where the page will be after it's finished scrolling. Any pointers?

• jquery set focus on dynamic content?

  - by Alan

  In jquery I've appended a <li> element to an unordered list. How do I focus on the newly created <li> ? If I do the following: $("ul").append('<li><input type="text">hi!</input></li>'); $("li:last").focus(); //doesn't work because new <li> isn't in dom yet the focus doesn't work, as noted above. I know jquery 1.4.2 has a live() event handler which allows you load event handlers to dynamically added elements, but I'm not sure what I'm doing wrong: $(document).ready(function () { $('li').live('load', function () { alert("hi!"); $("li:last").focus(); }); });

• "Randomly" occurring errors...

  - by ClarkeyBoy

  Hi, My website has a setup whereby when the application starts a module called SiteContent is "created". This runs a clearup function which basically deletes any irrelevant data from the database, in case any has been left in there from previously run functions. The module has instances of Manager classes - namely RangeManager, CollectionManager, DesignManager. There are others but I will just use these as an example. Each Manager class contains an array of items - items may be of type Range, Collection or Design, whichever one is relevant. Data for each range is then read into an instance of Range, Collection or Design. I know this is basically duplicating data - not very efficient but its my final year project at the moment so I can always change it to use Linq or something similar later, when I am not pressured by the one month deadline. I have a form which, on clicking the Save button, saves data by calling SiteContent.RangeManager.Create(vars) or SiteContent.RangeManager.Update(Range As Range, vars) (or the equivalent for other manager classes, whichever one happens to be relevant). These functions call a stored procedure to insert or update in the relevant table. Classes Range, Collection and Design all have attributes such as Name, Description, Display and several others. When the Create or Update function is called, the Manager loops through all the other items to check if an item with the same name already exists. The Update function ensures that it does not compare the item being updated to itself. A custom exception (ItemAlreadyExistsException) is thrown if another item with the same name is found. For some weird reason, if I go into a Range, Collection or Design in edit mode, change something and try to update it, it occasionally doesnt update the item. When I say occasionally I mean every 3 - 4 page loads, sometimes more. I see absolutely no pattern in when or why it occurs. I have a try-catch statement which catches ItemAlreadyExistsException, and outputs "An item with this name already exists" when caught. Occasionally it will output this; other times it will not. Does anyone have any idea why this could happen? Maybe a mistake which someone has made and solved before? I used to have regular expressions in place that the names were compared to - I believe it was [a-zA-Z]{1, 100} (between 1 and 100 lower- or upper-case characters). For some reason the customer who I am developing the site for used to get errors saying its not in the correct format. Yet he could try the same text 5 minutes later and it would work fine. I am thinking this could well be the same problem, since both problems occur at random. Many thanks in advance. Regards, Richard Clarke Edit: After much time spent narrowing down the code, I have decided to wait till my brother, who has been a programmer for at least 8 years more than I have, to come down over Easter and get him to have a look at it. If he cant solve it then I will zip the files up and put them somewhere for people to access and have a go at. I narrowed it down literally to the minimum number of files possible, and it still occurs. It seems to be about every 10th time. Having said that, I force the manager classes to refresh every 10 page loads or 5 minutes (whichever one is sooner). I may look into this - this could be causing a problem. Basically each Manager contains an array of an object. This array is populated using data from the database. The Update function takes an instance of the item and the new values to be set for the object. If it happens to be a page load where the array is reset (ie the data is loaded freshly from the database) then the object instance with the same ID wont be the same instance as the one being passed in. This explains the fact that it throws an ItemAlreadyExistsException now and then. It all makes sense now the more I think about it. If I were to pass in the ID of the object to be altered, rather than the object itself, then it should work perfectly. I will answer the question if I solve it..

• Variable in one query is getting into another query in view

  - by Jason Shultz

  I have two foreach statements. The variable from one one is somehow getting into another and i'm not sure how to fix it. Here's my controller: // Categories Page Code function categories($id) { $this->load->model('Business_model'); $data['businessList'] = $this->Business_model->categoryPageList($id); $data['catList'] = $this->Business_model->categoryList(); $data['featured'] = $this->Business_model->frontPageList(); $data['user_id'] = $this->tank_auth->get_user_id(); $data['username'] = $this->tank_auth->get_username(); $data['page_title'] = 'Welcome To Jerome - Largest Ghost Town in America'; $data['page'] = 'category_view'; // pass the actual view to use as a parameter $this->load->view('container',$data); } What happens is categories will only show the businesses in a certain category. The businesses are pulled from the database using the categoryPageList($id) function. Here is that function: function categoryPageList($id) { $this->db->select('b.id, b.busname, b.busowner, b.webaddress, p.thumb, v.title, c.catname, s.specname, p.thumb, c.id'); $this->db->from ('business AS b'); $this->db->where('b.category', $id); $this->db->join('photos AS p', 'p.busid = b.id', 'left'); $this->db->join('video AS v', 'v.busid = b.id', 'left'); $this->db->join('specials AS s', 's.busid = b.id', 'left'); $this->db->join('category As c', 'b.category = c.id', 'left'); $this->db->group_by("b.id"); return $this->db->get(); } And here is the view: <h2>Welcome to Jerome, Arizona</h2> <p>Choose the Category of Business you are interested in:<br/> <?php foreach ($catList->result() as $row): ?> <a href="/site/categories/<?=$row->id?>"><?=$row->catname?></a>, &nbsp; <?php endforeach; ?></p> <table id="businessTable" class="tablesorter"> <thead><tr><th>Business Name</th><th>Business Owner</th><th>Web</th><th>Photos</th><th>Videos</th><th>Specials</th></tr></thead> <?php if(count($businessList) > 0) : foreach ($businessList->result() as $crow): ?> <tr> <td><a href="/site/business/<?=$crow->id?>"><?=$crow->busname?></a></td> <td><?=$crow->busowner?></td> <td><a href="<?=$crow->webaddress?>">Visit Site</a></td> <td> <?php if(isset($crow->thumb)):?> yes <?php else:?> no <?php endif?> </td> <td> <?php if(isset($crow->title)):?> yes <?php else:?> no <?php endif?> </td> <td> <?php if(isset($crow->specname)):?> yes <?php else:?> no <?php endif?> </td> </tr> <?php endforeach; ?> <?php else : ?> <td colspan="4"><p>No Category Selected</p></td> <?php endif; ?> </table> The problem occurs here. <?=$crow->id?> should be showing the row id from the business table. Instead, it's showing the row ID of the category table. so, if i'm viewing /site/categories/6 <?=$crow->id?> will show 6 when it should be showing 10 (the row ID of the only business in that category at this time. How can I fix this?

• how many fps can iPhone's UIGetScreenImage() actually do?

  - by M Katz

  Now that Apple is officially allowing UIGetScreenImage() to be used in iPhone apps, I've seen a number of blogs saying that this "opens the floodgates" for video capture on iPhones, including older models. But I've also seen blogs that say the fastest frame rate they can get with UIGetScreenImage() is like 6 FPS. Can anyone share specific frame-rate results you've gotten with UIGetScreenImage() (or other approved APIs)? Does restricting the area of the screen captured improve frame rate significantly? Also, for the wishful thinking segment of today's program, does anyone have pointers to code/library that uses UIGetScreenImage() to capture video? For instance, I'd like an API something like Capture( int fps, Rect bounds, int durationMs ) that would turn on the camera and for the given duration record a sequence of .png files at the given frame rate, copying from the given screen rect.

• Are there any B-tree programs or sites that show visually how a B-tree works

  - by Phenom

  I found this website that lets you insert and delete items from a B-tree and shows you visually what the B-tree looks like: java b-tree I'm looking for another website or program similar to this. This site does not allow you to specify a B-tree of order 4 (4 pointers and 3 elements), it only lets you specify B-trees with an even number of elements. Also, if possible, I'd like to be able to insert letters instead of numbers. I think I actually found a different site but that was a while ago and can't find it anymore.

• Interface member name conflicts in ActionScript 3

  - by Aaron

  I am trying to create an ActionScript 3 class that implements two interfaces. The interfaces contain member functions with different signatures but the same name: public interface IFoo { function doStuff(input:int):void; } public interface IBar { function doStuff(input1:String, input2:Number):void; } public class FooBar implements IFoo, IBar { // ??? } In C# this problem can be solved with explicit interface implementations, but as far as I can tell ActionScript does not have that feature. Is there any way to create a class that implements both interfaces?

• plone.app.blob or z3c.blobfile?

  - by askvictor

  I need a blob file field as part of a content type in plone. plone.app.blob's BlobField should provide this, but I can't find how to get a URL to download the file including the original filename (e.g. http://plone.site/plone/obj/orig-file-name.avi). Is there a way to do this using plone.app.blob? Alternately, there are a few pointers on the web pointing to plone.namedfile to do this. plone.namedfile seems to rely on z3c.blobfile. How does z3c.blobfile differ from plone.app.blob? Is one of these methods better than the other? vik

• How to render Asian characters in a PDF using xhtmlrenderer

  - by Mark Derricutt

  I was wondering what steps were needed to render Asian characters using the java based xhtmlrenderer (flying saucer) library? I am wanting to render the following: <html> <body>????????</body> </html> Without any font settings being added to the HTML this renders fine in normal browsers, but I can't find anyway to render this to PDF using the iTextRenderer portion of xhtmlrenderer. After following various threads on the mailing list, I see lots of posts talking about adding .TTF files from the c:\windows\fonts directory, and I have modified the examples to run on linux ( https://gist.github.com/643173745182c9becc57 ), which shows me various fonts being displayed, but I don't see any Asian glyffs. Does anyone have any decent pointers, or clean solutions to this problem? Or am I looking at the wrong problem with a really simple solution elsewhere?

• Exception using SQLiteDataReader

  - by galford13x

  I'm making a Custom SQLite Wrapper. This is meant to allow a presistent connection to a database. However, I receive an exception when calling this function twice. public Boolean DatabaseConnected(string databasePath) { bool exists = false; if (ConnectionOpen()) { this.Command.CommandText = string.Format(DATABASE_QUERY); using (reader = this.Command.ExecuteReader()) { while (reader.Read()) { if (string.Compare(reader[FILE_NAME_COL_HEADER].ToString(), databasePath, true) == 0) { exists = true; break; } } reader.Close(); } } return exists; } I use the above function to check if the database is currently open before executing a command or trying to open a database. The first time I execute the function, it executes with no issue. After that the reader = this.Command.ExecuteReader() throws an exception Object reference not set to an instance of an object.

• passing json from servlet to dojo

  - by Moev4

  I am currently trying to pass a generated JSON string to dojo for parsing and am having some issues. The servlet simply writes it as a string as so: response.getWriter().append("{ \"data\": {"); response.getWriter().append("\"type\": \"facing\","); response.getWriter().append("\"score\": " + "\"" + score + "\","); response.getWriter().append("\"count\":" + "\"" + count + "\"" ); response.getWriter().append("}}"); which prints as: {"data":{"type":"facing","score":"10","count":"24"}} And the parsing on the dojo end looks as so: dojo.xhrPost({ url: url, handleAs: "json", load: function(data) { alert(data); /* Parse Not working */ alert(data.data[0].type); }, error: function(error) { alert("No dice") } }); The main issue is the data.data[0].type is returning nothing but when i print this out as text the json seems to be correctly formatted. Any help with this would be appreciated.
