• Internet Explorer not incrementing number for non-sibling <li> elements

  - by biagidp

  I've got some html that looks like this: <ol> <div> <li>one</li> </div> <div> <li>two</li> </div> <div> <li>three</li> </div> </ol> Which looks like this in Chrome/Firefox: 1. one 2. two 3. three But looks like this in IE: 1. one 1. two 1. three If I change the code so that the li element is the parent of the div element instead of the other way around (so that all the li elements are siblings) IE renders it correctly. Anyone know what causes this or if this is the intended working behavior of IE? Furthermore is one way technically more correct than the other? <div><li></li></div> VS. <li><div></div></li> Thanks, David

• cant calculate width of elements

  - by Kein

  I try to get width of dom objects: function resizeArea(){ var width = 0; area.children().each(function(i){ alert(this.offsetWidth); width += this.offsetWidth; }); area.css('width', width); } In get results: Chrome: 800 Opera: 708 FF: 783 IE: 714 But if see it in firebug, dragonfly and other debuggers i see correct 908px. I don't know where porblem. I run this fun after domloaded. Here is HTML and css of block: <div class="scroll_area" id="scroll"> <div class="area" id="area"> <div class="category"> [..] </div> </div> </div> <style> #scroll { position:realtive; width: 800px, heght: 400px; } #area { position:absolute; left: 0; top: 0; } #area .category, #area .category .text, #area .category .image{ width: 200px } </style> And that interesting. This function later work correctly, only at first run, for first calculating.

• LINQ-SQL Updating Multiple Rows in a single transaction

  - by RPM1984

  Hi guys, I need help re-factoring this legacy LINQ-SQL code which is generating around 100 update statements. I'll keep playing around with the best solution, but would appreciate some ideas/past experience with this issue. Here's my code: List<Foo> foos; int userId = 123; using (DataClassesDataContext db = new FooDatabase()) { foos = (from f in db.FooBars where f.UserId = userId select f).ToList(); foreach (FooBar fooBar in foos) { fooBar.IsFoo = false; } db.SubmitChanges() } Essentially i want to update the IsFoo field to false for all records that have a particular UserId value. Whats happening is the .ToList() is firing off a query to get all the FooBars for a particular user, then for each Foo object, its executing an UPDATE statement updating the IsFoo property. Can the above code be re-factored to one single UPDATE statement? Ideally, the only SQL i want fired is the below: UPDATE FooBars SET IsFoo = FALSE WHERE UserId = 123 EDIT Ok so looks like it cant be done without using db.ExecuteCommand. Grr...! What i'll probably end up doing is creating another extension method for the DLINQ namespace. Still require some hardcoding (ie writing "WHERE" and "UPDATE"), but at least it hides most of the implementation details away from the actual LINQ query syntax.

• How to do buffered intersection checks on an IPoint?

  - by Quigrim

  How would I buffer an IPoint to do an intersection check using IRelationalOperator? I have, for arguments sake: IPoint p1 = xxx; IPoint p2 = yyy; IRelationalOperator rel1 = (IRelationalOperator)p1; if (rel.Intersects (p2)) // Do something But now I want to add a tolerance to my check, so I assume the right way to do that is by either buffering p1 or p2. Right? How do I add such a buffer? Note: the Intersects method I am using is an extension method I wrote to simplify my code. Here it is: /// <summary> /// Returns true if the IGeometry is intersected. /// This method negates the Disjoint method. /// </summary> /// <param name="relOp">The rel op.</param> /// <param name="other">The other.</param> /// <returns></returns> public static bool Intersects ( this IRelationalOperator relOp, IGeometry other) { return (!relOp.Disjoint (other)); }

• slideDown() Makes Everything in Wrapper Shift

  - by Ben

  Hello everyone, I am currently creating a simple menu where there are several names of services and a user can click on one and jQuery will show it's corresponding paragraph describing it below it. My jQuery code is fine and does exactly what I want, however, I have one bug I have yet to iron out. Whenever I click one of these headings and it's description displays, everything in the wrapper for the page shifts to the left about 7 pixels in Firefox, it does the same thing is Google Chrome however I have not measured the amout but I am sure it is irrelevant. Anyways, I am using the slideToggle() command to show the hidden parragraph. I assume this is occuring because when the slideDown occurs it is somehow changing the width of everything and the "margin: 0 auto;" setting for the wrapper rule in my css is compensating for this change. Does anyone have any way I can remedy this problem? I have tried several other fixes I've found around the internet but to no avail. Here is what my code looks like, I put it on jsFiddle to make it easier to view: http://jsfiddle.net/vcH7m/ Feel free to edit it there if you like, or post what needs to be fixed here. Whatever is more convenient. Thank you very much for the help!

• How to .NET package JavaScript/bookmarklet as Interner Explorer 8/9 Plugin?

  - by Don

  How to .NET package JavaScript/bookmarklet as Interner Explorer 8/9 Plugin? I have recently finished writing JavaScript code for a browser addon, which basically (once the JS is included) runs on page-load, for given domains it then checks for certain elements in the DOM and adds new relevant elements(/information) to the page. Since the JavaScript only reads/affects the HTML DOM independently (and does not need any toolbar buttons or anything else) the JS purely needs adding to the browser's webpages. I have packaged the code to work with Firefox and Chrome and those are both working well, and I can run the code for IE in 'bookmarklet' form without problems, but I would like to learn how to package JavaScript as an actual .NET .MSI addon/plugin that will install for the current Internet Explorer 8/9. Does anyone know of a suitable guide or method I might refer to please? I have tried searching online for tutorials but most walkthroughs refer to writing the plugin body itself (which might involve unnecessary stages/includes) and are thus not regarding packing existing JS. I hope someone might have the solution please? Note: Someone packaged an old version for me as a MSI installer for Internet Explorer 7 a year ago, which installed into Program Files with a plugin.dll plugin.tlb and plugin.InstallState plus BandObjectLib.dll Interop.SHDocVw.dll and Microsoft.mshtml.dll if that is useful.

• Ant: use include and exclude together

  - by Ken

  OK, this seems like it should be really simple. I'm using Apache Ant 1.8, and I have a target which does: <delete file="output/program.tar.bz2"/> <tar basedir="input" destfile="output/program.tar.bz2" compression="bzip2"> <tarfileset dir="input"> <include name="goodfolder1/**"/> <include name="goodfolder2/**"/> <exclude name="**/badfile"/> <exclude name="**/*.badext"/> </tarfileset> </tar> I want it to make a .tar.bz2 of input/goodfolder1 and input/goodfolder2, excluding files named "badfile", and excluding files with extension ".badext". It's giving me a .tar.bz2, but it's including badfile and *.badext -- the excludes seem to be ignored. The order of include/exclude doesn't seem to make a difference. I tried wrapping the includes/excludes in a (the docs say it's implicit?), but it made no difference. I'm sure there's something simple I'm missing, since the manual has a very similar example, though in a somewhat different context. EDIT: It looks like it could be related to the dir="input" attribute: it's adding everything in "input", and then adding everything in the tarfileset to that. Files I want appear twice in the program.tar.bz2, but files that are excluded only appear once. But dir is mandatory, and I don't see how this is different from the examples in the manual.

• How do you move an admin menu item in Magento

  - by Josh Pennington

  I currently have an extension that I created and it currently sits inside of its own top level menu. I would like to move it so that the item would appear inside of the Customers menu. Does anyone know how to do this? It looks like this is handled inside the extensions config.xml file. The code that I have for it right now is as follows: <menu> <testimonials module="testimonials"> <title>Testimonials</title> <sort_order>71</sort_order> <children> <items module="testimonials"> <title>Manage Items</title> <sort_order>0</sort_order> <action>testimonials/adminhtml_testimonials</action> </items> </children> </testimonials> </menu> I tried changing the title element to Customers and it just created a duplicate Customers menu. Does anyone have any ideas? Thanks Josh Pennington

• Trouble decoding JSON string with PHP

  - by Anthony

  I'm trying to send an array of objects from JS to PHP using JSON. I have an array of players as follows: var player; var players = new Array(); //loop for number of players player = new Object(); player.id = theID; players[i] = player; Then my AJAX call looks like this: JSONplayers = JSON.stringify(players); $.ajax({ type: "POST", url: "php/ajax_send_players.php", data: { "players" : JSONplayers } On the PHP side the decode function looks like this $players = $_REQUEST['players']; echo var_dump($players); $players = json_decode($players); echo 'players: ' .$players. '--'. $players[0] . '--'. $players[0]->id; Debugging in chrome, the JSON players var looks like this before it is sent: JSONplayers: "[{"id":"Percipient"},{"id":"4"}]" And when I vardump in PHP it looks OK, giving this: string(40) "[{\"id\":\"Percipient\"},{\"id\":\"4\"}]" But I can't access the PHP array, and the echo statement about starting with players: outputs this: players: ---- Nothing across the board...maybe it has something to do with the \'s in the array, I am new to this and might be missing something very simple. Any help would be greatly appreciated. note I've also tried json_decode($players, true) to get it as an assoc array but get similar results.

• Centralized Exception handling for Eclipse plug-in

  - by Svilen

  Hello, At first I thought this would be question often asked, however trying (and failing) to look up info on this proved me wrong. Is there a mechanism in Eclipse platform for centralized exception handling of exceptions? For example... You have plug-in project which connects to a DB and issues queries, results of which are used to populate some e.g. views. This is like the most common example ever. :) Queries are executed almost for any user action, from every UI control the plug-in provides. Most likely the DB Query API will have some specific to the DB SomeDBGeneralException declared as being thrown by it. That's OK, you can handle those according to whatever your software design is. But how about unchecked exceptions which are likely to occur, e.g. , when communication with DB suddenly breaks for some network related reason? What if in such case one would like to catch those exceptions in a central place and for example provide user friendly message to the user (rather than the low level communication protocol api messages) and even some possible actions the user could execute in order to deal with the specific problem? Thinking in Eclipse platform context, the question may be rephrased as "Is there an extension point like "org.eclipse.ExceptionHandler" which allows to declare exception handlers for specific (some kind of filtering support) exceptions giving a lot of flexibility with the actual handling?"

• Javascript not working in firefox

  - by Samuel Meddows

  Hi guys, I have a PHP form validation function that I developed in chrome and now will not work in firefox or Opera. The function checks to see if a section of the form is blank and shows and error message. If there is no error then then the form submits through document.events.submit(); CODE: function submit_events() { //Check to see if a number is entered if the corosponding textbox is checked if (document.events.dj_card.checked == true && dj_amount.value==""){ //Error Control Method //alert ('You didn\'t enetr an Amount for DJ\'s Card!'); var txt=document.getElementById("error") txt.innerHTML="<p><font color=\"#FF0000\"> You didn\'t enetr an Amount for DJ\'s Card!</font></p>"; window.document.getElementById("dj_card_label").style.color = '#FF0000'; //Reset window.document.getElementById("company_amount_label").style.color = '#000000'; window.document.getElementById("own_amount_label").style.color = '#000000'; }else{ document.events.submit(); } The document.events.submit();does work across all my browsers however the check statements do not. If the box is not ticked the form submits. If the box is ticked it does not matter whether there is data in the dj_amount.value or not. The form will not submit and no error messages are displayed. Thanks guys.

• Is there some formal way to update the browser detection files for ASP.Net?

  - by Deane

  I have an ASP.Net site on which we're using control adapters. We have the adapters mapped to a "refID" of "Default." These adapters are working fine on all browsers except Chrome and Safari. For those browsers, they do not execute. I've given up trying to figure out why -- I have a question here on SO that no one has been able to answer, and I've been researching it for days now. It's just inexplicable. I have tested the same code in my local environment, and it works just fine. Additionally, no one else can replicate my problem on other servers. It seems to be somehow confined to the machines at my client's site. Could they be somehow out-of-date? If this is the case, is there some way to "update" the .browser files? I'm half-tempted to just copy the .browser files out of the Framework directory from my machine over to theirs, but I'm curious is there's something more formal than this? Is there some other source of data that ASP.Net uses for browser detection other than these files?

• How to debug a Gruntfile with breakpoints using node-inspector?

  - by Kris Hollenbeck

  So I have spent the past couple days trying to get this to work with no luck. Most of the solutions I have found seem to work "okay" for debugging node applications. But I haven't had much luck debugging grunt stand alone. I would like to be able to set breakpoints in my gruntfile and either step through the code with either the browser or an IDE. I have tried the following: Debugging using intelliJ IDE Using Grunt Console (Process finished with exit code 6) Debugging with Nodeeclipse (This sort of works okay but doesn't hit the breakpoints set in eclipse, not very intuitive) Debugging using node-inspector (This one also sort of works. I can step through a little ways using F11 and F10 in chrome. But eventually it just crashes. Using F8 to skip to break point never works.) ERROR MESSAGE USING NODE-INSPECTOR So currently node-inspector feels like it has gotten me the closest to what I want. To get here I did the following: From my grunt directory I ran the following commands: grunt node-inspector node --debug-brk Gruntfile.js And then from there I went to localhost:8080/debug?port=5858 to debug my Gruntfile.js. But like I mentioned above, as soon as I hit F8 to skip to breakpoint it crashes with the above error. Has anybody had any success using this method to try to debug a Gruntfile? So far from my search efforts I have not found a very well documented way of doing this. So hopefully this will be useful or beneficial information for future users. Also I am using Windows 7 by the way. Thanks in advance.

• javascript to select text from web page

  - by phil swenson

  I'm trying to write a bookmarklet that grabs any selected text on a web page and sends it to my website. It should (hopefully) work in Chrome, FFX, Safari, and IE. I did a search and found a function, but it doesn't appear to work. Here is the code: <html> <body> <div onClick=getSelText()>Click</div> <div>please select me</div> </body> <script language=javascript> function getSelText(){ var txt = 'nothing'; if (window.getSelection){ txt = "1" + window.getSelection(); } else if (document.getSelection) { txt = "2" + document.getSelection(); } else if (document.selection) { txt = "3" + document.selection.createRange().text; } else return; alert("selected text = " + txt); } </script> </html> when I select the text in the div "please select me" and hit the click div, I just get "selected text = 1" thanks

• How to write this snippet in Python?

  - by morpheous

  I am learning Python (I have a C/C++ background). I need to write something practical in Python though, whilst learning. I have the following pseudocode (my first attempt at writing a Python script, since reading about Python yesterday). Hopefully, the snippet details the logic of what I want to do. BTW I am using python 2.6 on Ubuntu Karmic. Assume the script is invoked as: script_name.py directory_path import csv, sys, os, glob # Can I declare that the function accepts a dictionary as first arg? def getItemValue(item, key, defval) return !item.haskey(key) ? defval : item[key] dirname = sys.argv[1] # declare some default values here weight, is_male, default_city_id = 100, true, 1 # fetch some data from a database table into a nested dictionary, indexed by a string curr_dict = load_dict_from_db('foo') #iterate through all the files matching *.csv in the specified folder for infile in glob.glob( os.path.join(dirname, '*.csv') ): #get the file name (without the '.csv' extension) code = infile[0:-4] # open file, and iterate through the rows of the current file (a CSV file) f = open(infile, 'rt') try: reader = csv.reader(f) for row in reader: #lookup the id for the code in the dictionary id = curr_dict[code]['id'] name = row['name'] address1 = row['address1'] address2 = row['address2'] city_id = getItemValue(row, 'city_id', default_city_id) # insert row to database table finally: f.close() I have the following questions: Is the code written in a Pythonic enough way (is there a better way of implementing it)? Given a table with a schema like shown below, how may I write a Python function that fetches data from the table and returns is in a dictionary indexed by string (name). How can I insert the row data into the table (actually I would like to use a transaction if possible, and commit just before the file is closed) Table schema: create table demo (id int, name varchar(32), weight float, city_id int); BTW, my backend database is postgreSQL

• Binding ComboBoxes to enums... in Silverlight!

  - by Domenic

  So, the web, and StackOverflow, have plenty of nice answers for how to bind a combobox to an enum property in WPF. But Silverlight is missing all of the features that make this possible :(. For example: You can't use a generic EnumDisplayer-style IValueConverter that accepts a type parameter, since Silverlight doesn't support x:Type. You can't use ObjectDataProvider, like in this approach, since it doesn't exist in Silverlight. You can't use a custom markup extension like in the comments on the link from #2, since markup extensions don't exist in Silverlight. You can't do a version of #1 using generics instead of Type properties of the object, since generics aren't supported in XAML (and the hacks to make them work all depend on markup extensions, not supported in Silverlight). Massive fail! As I see it, the only way to make this work is to either Cheat and bind to a string property in my ViewModel, whose setter/getter does the conversion, loading values into the ComboBox using code-behind in the View. Make a custom IValueConverter for every enum I want to bind to. Are there any alternatives that are more generic, i.e. don't involve writing the same code over and over for every enum I want? I suppose I could do solution #2 using a generic class accepting the enum as a type parameter, and then create new classes for every enum I want that are simply class MyEnumConverter : GenericEnumConverter<MyEnum> {} What are your thoughts, guys?

• WebView and HTML5 <video>

  - by brian moore

  I'm piecing together a cheapo app that amongst other things "frames" some of our websites... Pretty simple with the WebViewClient... until I hit the video. The video is done as HTML5 elements, and these work fine and dandy on Chrome, iPhones, and now that we fixed the encoding issues it works great on Android... in the native browser. Now the rub: WebView doesn't like it. At all. I can click on the poster image, and nothing happens. Googling, I found http://www.codelark.com/2010/05/12/android-viewing-video-from-embedded-webview/ which is close, but seems to be based on a 'link' (as in a href...) instead of a video element. (onDownloadListener does not appear to get invoked on video elements...) I also see references to overriding onShowCustomView, but that seems to not get called on video elements... nor does shouldOverrideUrlLoading.. I would rather not get into "pull xml from the server, reformat it in the app".. by keeping the story layout on the server, I can control the content a bit better without forcing people to keep updating an app. So if I can convince WebView to handle tags like the native browser, that would be best. I'm clearly missing something obvious.. but I have no clue what.

• Asp.net Hidden field not having value in code behind, but *is* retaining value after postbacks

  - by KallDrexx

  In my ASCX, I have an asp.net hidden field defined as <asp:HiddenField ID="hdnNewAsset" runat="server" />. In the Code Behind I have the following code: protected void Page_Load(object sender, EventArgs e) { _service = new ArticleDataService(PortalId); if (!IsPostBack) { string rawId = Request[ArticleQueryParams.ArticleId]; DisplayArticleDetails(rawId); } if (hdnNewAsset.Value.Trim() != string.Empty) ProcessNewAsset(); } Now, in my frontend, I have a javascript function to react to an event and set the hidden field and trigger a postback: function assetSelected(assetGuid) { $('input[id*="hdnNewAsset"]').val(assetGuid); __doPostBack() } What's happening is that my hidden field is being set in the markup (chrome shows [ <input type=?"hidden" name=?"dnn$ctr466$Main$ctl00$hdnNewAsset" id=?"dnn_ctr466_Main_ctl00_hdnNewAsset" value=?"98d88e72-088c-40a4-9022-565a53dc33c4">? ] for $('input[id*="hdnNewAsset"]')). However, when the postback occurs, hdnNewAsset.Value is an empty string. What's even more puzzling is that at the beginning of Page_Load Request.Params["dnn$ctr466$Main$ctl00$hdnNewAsset"] shows 98d88e72-088c-40a4-9022-565a53dc33c4, and after the postback my hidden field has the same value (so the hidden field is persisting across postbacks), yet I cannot access this value via hdnNewAsset.Value. Can anyone see what I"m doing wrong?

• Twitter bootstrap modal loads wrong remote data

  - by Victor S

  I'm using Twitter Bootstrap modal featurs and loading data from remote locations. I'm providing the remote url for a set of thumbnails with the hope that once the thumbnail is clicked, the appropriate data (a large version of the image) is displayed. I'm using the html declarative style to define the remote urls and all the features of the modal. What I find is that Twitter bootstrap modal loads first remote url then does not display subsequent remote data, (although a request to the proper url is made in Chrome) but displays first loaded data always. How do I get it to show the proper data? View: #gallery-navigation %ul - @profile.background_images.each do |image| %li = link_to image_tag(image.background_image.url(:thumb)), remote_image_path(image.id), :role => "button", :data => {:toggle => "modal", :target => "#image-modal", :remote => remote_image_path(image.id)}, :id => "image-modal" / Modal #image-modal.modal.hide.fade(role="dialog" aria-hidden="true" data-backdrop="true") .modal-body Controller: def remote_image @image = current_user.profile.background_images.find(params[:image_id]) respond_to do |format| format.html { render :partial => "remote_image", :locals => { :image => @image } } end end

• jQuery ajax post of jpg image to .net webservice. Image results corrupted

  - by sosergio

  I have a phonegap jquery app that opens the camera and take a picture. I then POST this picture to a .net webservice, wich I've coded. I can't use phonegap FileTransfer because such isn't supported by Bada os, wich is a requirement. I believe I've successfully loaded the image from phonegap FileSystem API, I've attached it into an .ajax type:post, I've even received it from .net side, but when .net save the image into the server, the image results corrupted. It seems to me that two sides of the communication have different data type. Has anyone experience in this? Any help will be appreciated. This is my code: //PHONEGAP CAMERA ACCESS (summed up) navigator.camera.getPicture(onGetPictureSuccess, onGetPictureFail, { quality: 50, destinationType:Camera.DestinationType.FILE_URI }); window.resolveLocalFileSystemURI(imageURI, onResolveFileSystemURISuccess, onResolveFileSystemURIError); fileEntry.file(gotFileSuccess, gotFileError); new FileReader().readAsDataURL(file); //UPLOAD FILE function onDataReadSuccess(evt) { var image_data = evt.target.result; var filename = unique_id(); var filext = "jpg"; $.ajax({ type : 'POST', url : SERVICE_BASE_URL+"/fotos/"+filename+"?ext="+filext, cache: false, timeout: 100000, processData: false, data: image_data, contentType: 'image/jpeg', success : function(data) { console.log("Data Uploaded with success. Message: "+ data); $.mobile.hidePageLoadingMsg(); $.mobile.changePage("ok.html"); } }); } On my .net Web Service this is the method that gets invoked: public string FotoSave(string filename, string extension, Stream fileContent) { string filePath = HttpContext.Current.Server.MapPath("~/foto_data/") + "\\" + filename; FileStream writeStream = new FileStream(filePath, FileMode.OpenOrCreate, FileAccess.Write); int Length = 256; Byte[] buffer = new Byte[Length]; int bytesRead = readStream.Read(buffer, 0, Length); // write the required bytes while (bytesRead > 0) { writeStream.Write(buffer, 0, bytesRead); bytesRead = readStream.Read(buffer, 0, Length); } readStream.Close(); writeStream.Close(); }

• How to buffer an IPoint or IGeometry? (How to do buffered intersection checks on an IPoint?)

  - by Quigrim

  How would I buffer an IPoint to do an intersection check using IRelationalOperator? I have, for arguments sake: IPoint p1 = xxx; IPoint p2 = yyy; IRelationalOperator rel1 = (IRelationalOperator)p1; if (rel.Intersects (p2)) // Do something But now I want to add a tolerance to my check, so I assume the right way to do that is by either buffering p1 or p2. Right? How do I add such a buffer? Note: the Intersects method I am using is an extension method I wrote to simplify my code. Here it is: /// <summary> /// Returns true if the IGeometry is intersected. /// This method negates the Disjoint method. /// </summary> /// <param name="relOp">The rel op.</param> /// <param name="other">The other.</param> /// <returns></returns> public static bool Intersects ( this IRelationalOperator relOp, IGeometry other) { return (!relOp.Disjoint (other)); }

• BASH: How to count all the human readable files?

  - by user1687406

  I'm taking an intro course to UNIX and have a homework question that follows: How many files in the previous question are text files? A text file is any file containing human-readable content. (TRICK QUESTION. Run the file command on a file to see whether the file is a text file or a binary data file! If you simply count the number of files with the ".txt" extension you will get no points for this question.) The previous question simply asked how many regular files there were, which was easy to figure out by doing find . -type f | wc -l I'm just having trouble determining what "human readable content" is, since I'm assuming it means anything besides binary/assembly, but I thought that's what -type f displays. Maybe that's what the professor meant by saying "trick question"? This question has a follow up later that also asks "What text files contain the string "csc" in any mix of upper and lower case?". Obviously "text" is referring to more than just .txt files, but I need to figure out the first question to determine this!
