  • What kind of cost does Symbian require?

    - by httpinterpret
    Quoted from this answer: Cost of tools: JavaME would be cheapest, followed by Symbian, Android then iPhone. I want to get started with mobile phone programing,but I don't see where Symbian does cost, as its SDK is available for free. Anyone knows? BTW,many people say Symbian only supports Symbian C++, but after reading its document, it seems it also support Java, is this feature newly added?

  • Can I Automap a tree hierarchy with Fluent NHibernate?

    - by NakChak
    Is it possible to auto map a simple nested object structure? Something like this: public class Employee : Entity { public Employee() { this.Manages = new List<Employee>(); } public virtual string FirstName { get; set; } public virtual string LastName { get; set; } public virtual bool IsLineManager { get; set; } public virtual Employee Manager { get; set; } public virtual IList<Employee> Manages { get; set; } } It causes the following error at run time: Repeated column in mapping for collection: SharpKtulu.Core.Employee.Manages column: EmployeeFk Is it possible to automap this sort of structure, or do I have override the auto mapper for this sort of structure?

  • finding an adjacent node in xml through xpath

    - by kolosy
    i have a deeply nested structure (actually parsing out xhtml, so lots of nasty), like so: <tr> <td> <font id="blah"> stuff </font> </td> </tr> <tr> <td> more stuff </td> </tr> and this repeats in a long table. i need an xpath expression that will select the second font tag (or rather it's text()). i was looking at the preceding-sibling axis, but something isn't quite working right. something along the lines of (and pardon me if this is ridiculous, my xpath is rusty) //tr[preceding-sibling::tr/td/font/b]/td/text()

  • Ajax request gets to server but page doesn't update - Rails, jQuery

    - by Jesse
    So I have a scenario where my jQuery ajax request is hitting the server, but the page won't update. I'm stumped... Here's the ajax request: $.ajax({ type: 'GET', url: '/jsrender', data: "id=" + $.fragment().nav.replace("_link", "") }); Watching the rails logs, I get the following: Processing ProductsController#jsrender (for 127.0.0.1 at 2010-03-17 23:07:35) [GET] Parameters: {"action"=>"jsrender", "id"=>"products", "controller"=>"products"} ... Rendering products/jsrender.rjs Completed in 651ms (View: 608, DB: 17) | 200 OK [http://localhost/jsrender?id=products] So, it seems apparent to me that the ajax request is getting to the server. The code in the jsrender method is being executed, but the code in the jsrender.rjs doesn't fire. Here's the method, jsrender: def jsrender @currentview = "shared/#{params[:id]}" respond_to do |format| format.js {render :template => 'products/jsrender.rjs'} end end For the sake of argument, the code in jsrender.rjs is: page<<"alert('this works!');" Why is this? I see in the params that there is no authenticity_token, but I have tried passing an authenticity_token as well with the same result. Thanks in advance.

  • Why nginx doesn't have log for mobile request which is developed under Titanium Appcelerator?

    - by Vicheanak
    I have sent a request from both iphone and android platform to nginx server nginx/0.7.67 + Phusion Passenger 2.2.15 with this code in ruby: log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; but when I check on /conf/nginx.conf file I didn't see any log appears.

  • How to extract a Sub-Matrix from a Matrix ?

    - by ZaZu
    Hello, I have a matrix in a txt file and I want to load the matrix based on my input of number of rows and columns For example, I have a 5 by 5 matrix in the file. I want to extract a 3 by 3 matrix, how can I do that ? I created a nested loop using : FILE *sample sample=fopen("randomfile.txt","r"); for(i=0;i<rows;i++){ for(j=0;j<cols;j++){ fscanf(sample,"%f",&matrix[i][j]); } fscanf(sample,"\n",&matrix[i][j]); } fclose(sample); Sadly the code does not work .. If I have this matrix : 5.00 4.00 5.00 6.00 5.00 4.00 3.00 25.00 5.00 3.00 4.00 23.00 5.00 2.00 352.00 6.00 And inputting 3 for rows and 3 for columns, I get : 5.00 4.00 5.00 6.00 5.00 4.00 3.00 25.00 5.00 Which is obviously wrong , its reading line by line rather than skipping the unmentioned column ... What am I doing wrong ? Thanks !

  • Javascript onclick() event bubbling - working or not?

    - by user1071914
    I have a table in which the table row tag is decorated with an onclick() handler. If the row is clicked anywhere, it will load another page. In one of the elements on the row, is an anchor tag which also leads to another page. The desired behavior is that if they click on the link, "delete.html" is loaded. If they click anywhere else in the row, "edit.html" is loaded. The problem is that sometimes (according to users) both the link and the onclick() are fired at once, leading to a problem in the back end code. They swear they are not double-clicking. I don't know enough about Javascript event bubbling, handling and whatever to even know where to start with this bizarre problem, so I'm asking for help. Here's a fragment of the rendered page, showing the row with the embedded link and associated script tag. Any suggestions are welcomed: <tr id="tableRow_3339_0" class="odd"> <td class="l"></td> <td>PENDING</td> <td>Yabba Dabba Doo</td> <td>Fred Flintstone</td> <td> <a href="/delete.html?requestId=3339"> <div class="deleteButtonIcon"></div> </a> </td> <td class="r"></td> </tr> <script type="text/javascript">document.getElementById("tableRow_3339_0").onclick = function(event) { window.location = '//edit.html?requestId=3339'; };</script>

  • Browse asp.net development server from usb attached itouch

    - by Jim Maguire
    I can browse using the desktop browsers via ..localhost:54647/... and from windows mobile emulators via my gateway ..//192.168.0.199:54647/..., but neither method works from either my Android emulator or from a usb attached itouch. I know I may have to run IIS locally but it's more convenient to run the development server from Visual Studio 2008. I'm running Vista with latest service packs. I'm developing a mobile app using ASP.Net MVC. Thanks!

  • how to model editing of multiple related resources on the same webpage?

    - by amikazmi
    Lets say we have a Company model, that has many Employees And has many Projects If we want to show the projects, we'll go to "/company/1/projects/index" If we want to edit 1 project, we'll go to "/company/1/projects/1/edit" What if we want to edit all the projects at once on the same webpage? We can go to "/company/1/edit" and put a nested forms for all the projects But what if we need a different webpage to edit all the employees at once too? We can't use "/company/1/edit" again.. Right now we do "/company/1/projects/multiedit", "/company/1/projects/multupdate"- but as you can see, it's not rest. How can we model this restfully?

  • The same C# code produces different output in Visio Professional and Premium

    - by user615993
    I have built a simple conversion Add In, but its behavior is unfortunately different with the different Visio Editions (Visio 2010 Professional and Visio 2010 Premium). The Add In takes a Process-Diagram created with Shapes from Stencil_1.vss and creates a new slightly different Process-Diagram with Shapes from Stencil_2.vsd. It loops through a Visio page and for each shape founded creates a new shapes from new master shape (from Stencil_2.vsd) and drop it into the new page. Geometry, captions etc. are the same, only the shape-appearance is changed. Below is the source diagram: When I run the code into Visio 2010 Professional the swimlane shapes are drawn correctly. When I run the same code from Visio Premium the swimlane appearance and layout are mismatched: Both times i drop the SAME Shape("Swimlane" from the same stencil) into the Page with the SAME Code fragment: Visio.Master vm = swimlane_stencil.Masters.get_ItemU(@"Swimlane"); Visio.Shape TargetShape = targetPage.Drop(vm, shape_x, shape_y); How could I ensure, that the code produces any time the same (correct) output? Must I disable any (premium)features in the swimlane-shapesheet?

  • Efficiency of PHP arrays cast as objects?

    - by keithjgrant
    From what I understand, PHP objects are generally much faster than arrays. How is that efficiency affected if I'm typecasting to define stdClass objects on the fly: $var = (object)array('one' => 1, 'two' => 2); If the code doing this is deeply-nested, will I be better off explicitly defining $var as an objects instead: $var = new stdClass(); $var->one = 1; $var->two = 2; Is the difference negligible since I'll then be accessing $var as an object from there on, either way?

    - by Dan B
    I am using Rails 2.1 to output tables from a database. But the output includes lots of extra lines and tabs. I am using a while loop with lots of nested if statements. I am also wrapping all of my non-output lines in <%- code -%. Any idea what might be happening and a solution? Thanks, ex: <tr> <td>Some data</td> <td>more data</td>

  • nextSibling difference between IE and FF?

    - by Ahmet Yildirim
    Hi fellows, I just wrote a javascript code for layering in raphaeljs it works perfectly on FF. But it doesn't on IE. The problem is IE returns null for nextSibling for any object. How does one use it correctly, or is there a nextElementSibling call in IE? Here is the code fragment I used to change the order of objects: n = items[selected_item_id].nextSibling.id; if (n != '') { items[selected_item_id].insertAfter(items[n]); } <div id="consarea"> <svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="100%" height="100%"> <desc>Created with Raphaël</desc> <defs/> <rect x="188" y="100" width="200" height="200" r="10" rx="10" ry="10" fill="#ee8515" stroke="none" style="opacity: 1;" opacity="1"/> <rect x="253" y="158" width="50" height="50" r="0" rx="0" ry="0" fill="#0080ff" stroke="none" style="opacity: 1;" opacity="1" id="0"/> <rect x="230" y="140" width="50" height="50" r="0" rx="0" ry="0" fill="#c03022" stroke="none" style="opacity: 1;" opacity="1" id="1"/></svg> here it is above. the piece of the html im working on

  • Process every pair in a sequence

    - by Henry Jackson
    I'm looking for a concise way to process every (unordered) pair of elements in a sequence in .NET. I know I can do it with nested foreach loops, but I was looking for something a little more readable. I was imagining something like a modified Any() extension method: IEnumerable<Transaction> transactions = ... if (transactions.AnyPair( (first, second) => first.UniqueID == second.UniqueID)) throw ... Or maybe a foreach-style one: IEnumerable<JigsawPiece> pieces = ... pieces.ForEachPair( (first, second) => { TryFit(first, second); }); This question has been asked for other languages (e.g. see http://stackoverflow.com/questions/942543/operation-on-every-pair-of-element-in-a-list), but I'm looking for a .NET solution.

  • How to determine a text block of a file in one version come from which file in the previous version?

    - by Muhammad Asaduzzaman
    The problem is described below: Suppose I have a list of files in one version(say A,B,C,D). In the next version I have the following files(A,E,F,G). There are some similarities in their contents. The files in the later version comes from the previous version by file name renaming, content addition, deletion or partial modification or without any change( for example A is not changed). I take a block of text from a file(E, 2nd version) and check which files(in the 1st version) contain this text block. I found that B,C and D contain the text fragment. I want to determine from which file(B or c or d) this text block actually comes from.(I assume that E is a file whose name change in the second version). Since the contents may be changed, added or deleted in the later version, so in order to determine similarity I use LCS algorithm. But I cannot map the file with its previous version. I think one possible approach might be to use the location information of the match text blocks. But this heuristics not always work. Is there any research or algorithm exist to find so. Any direction will be helpful. Thanks in advance.

  • C# Linq: Restructuring object

    - by Ben
    I'd like to take an object like this: SortedList<string, SortedList<int, SortedList<DateTime, double>>> Data and, for a given 'int' value (key of first nested sorted list), restructure it like this: SortedList<DateTime, SortedList<string, double>> or, better yet, this: SortedList<DateTime, double[]> where each 'double[]' has as many elements as there are KeyValue pairs in the SortedList. I'm guessing Linq is the way to go, but can't figure it out. Thanks for any suggestions.

  • Displaying change of content through parent

    - by Mikhail
    I have DHTML content inside a fieldset. This includes plain html, nested objects (even other fieldsets), and value change of input, select, and textarea objects. I'd like to change the border of the fieldset if the contents have been changed. The following works: $('fieldset[name=qsfs127]').children('input').change(function(){ $(this).parent('fieldset').css({border:'1px solid red'}); }) This handles the input; I can extend it to select and textarea. Questions: How can I do the same for html changes? Can all of this change-tracking be done by comparing current html() to stored one? If yes for (2), will this handle cases of "undo"? Edit: I have a button that ajax-uploads contents, and saves the changes. I then remove the border color

  • gl_FragColor and glReadPixels

    - by chun0216
    I am still trying to read pixels from fragment shader and I have some questions. I know that gl_FragColor returns with vec4 meaning RGBA, 4 channels. After that, I am using glReadPixels to read FBO and write it in data GLubyte *pixels = new GLubyte[640*480*4]; glReadPixels(0, 0, 640,480, GL_RGBA, GL_UNSIGNED_BYTE, pixels); This works fine but it really has speed issue. Instead of this, I want to just read RGB so ignore alpha channels. I tried: GLubyte *pixels = new GLubyte[640*480*3]; glReadPixels(0, 0, 640,480, GL_RGB, GL_UNSIGNED_BYTE, pixels); instead and this didn't work though. I guess it's because gl_FragColor returns 4 channels and maybe I should do something before this? Actually, since my returned image (gl_FragColor) is grayscale, I did something like float gray = 0.5 //or some other values gl_FragColor = vec4(gray,gray,gray,1.0); So is there any efficient way to use glReadPixels instead of using the first 4 channels method? Any suggestion? By the way, this is on opengl es 2.0 code.

  • IE Print CSS and spanning page breaks

    - by DA
    I've been working on trying to fix an issue with print CSS and IE where things would disappear when printing in landscape mode. It appears the issue is that the element I'm trying to print (a large DIV with content inside it) spans two pages when put into landscape mode. What is happening is when the element spans two pages, the first page is blank, and the second page is printing what would normally be left over from the first page. I think it's related to contained floats: wrapper div floated div1 floated div2 If I set the two nested divs to float: none in the print CSS file, then IE will print them, albeit not in the layout we'd like. Before I spend another hour on this, anyone know what, specifically, is the issue here and if there's a known workaround?

  • How can I embed a conditional comment for IE with innerHTML?

    - by Samuel Charpentier
    Ok so I want to conditionally add this line of code; <!--[if ! IE]> <embed src="logo.svg" type="image/svg+xml" /> <![endif]--> Using: document.getElementById("logo") .innerHTML='...'; In a if()/else() statement and it don't write it! If i get rid of the selective comment ( <!--[if ! IE]><![endif]-->) and only put the SVG ( <embed src="logo.svg" type="image/svg+xml" /> ) it work! what should I do? I found a way around but i think in the Android browser the thing will pop up twice. here's what I've done ( and its Validated stuff!); <!DOCTYPE html> <html> <head> <META CHARSET="UTF-8"> <title>SVG Test</title> <script type="text/javascript"> //<![CDATA[ onload=function() { var ua = navigator.userAgent.toLowerCase(); var isAndroid = ua.indexOf("android") > -1; //&& ua.indexOf("mobile"); if(isAndroid) { document.getElementById("logo").innerHTML='<img src="fin_palais.png"/>'; } } //]]> </script> </head> <body> <div id="logo"> <!--[if lt IE 9]> <img src="fin_palais.png"/> <![endif]--> <!--[if gte IE 9]><!--> <embed src="fin_palais.svg" type="image/svg+xml" /> <!--<![endif]--> </div> </body>

  • Using WiX, how do I change a property of a subfolder of a virtual directory?

    - by Joergen Bech
    I have a hierarchy of Directory elements in a WiX script. I also have a component that creates a virtual directory (using IIS:WebVirtualDir), which points to the root of my Directory hierarchy. How do I change a property (e.g. AnonymousAccess) of a subfolder of the virtual directory, e.g. MyVirtualDir <<< this is the virtual directory root MyVirtualDir\MySubFolder <<< this is the subfolder for which I wish to change a property using WebDirProperties Please note that I do not wish to create a new virtual directory for the subfolder. I only wish to change a few security settings. The current script is too big to post here, but take a look at the WiX tutorial: 5.3 Web Directory. Suppose in that example that there was another Directory element named "MySubFolder" nested within the "InstallDir" element. What would then be the next step in order to set properties for "MySubFolder" without turning it into a virtual directory?

  • Architecture of a single-page JavaScript web application?

    - by fig-gnuton
    How should a complex single-page JS web application be structured on the client-side? Specifically I'm curious about how to cleanly structure the application in terms of its model objects, UI components, any controllers, and objects handling server persistence. MVC seemed like a fit at first. But with UI components nested at various depths (each with their own way of acting on/reacting to model data, and each generating events which they themselves may or may not handle directly), it doesn't seem like MVC can be cleanly applied. (But please correct me if that's not the case.) -- (This question resulted in two suggestions of using ajax, which is obviously needed for anything other than the most trivial one-page app.)
