  • Git Workflow With Capistrano

    - by jerhinesmith
    I'm trying to get my head around a good git workflow using capistrano. I've found a few good articles, but I'm either not grasping completely what they're suggesting (likely) or they're somewhat lacking. Here's kind of what I had in mind so far, but I get caught up when to merge back into the master branch (i.e. before moving to stage? after?) and trying to hook it into capistrano for deployments: Make sure you’re up to date with all the changes made on the remote master branch by other developers git checkout master git pull Create a new branch that pertains to the particular bug you're trying to fix git checkout -b bug-fix-branch Make your changes git status git add . git commit -m "Friendly message about the commit" So, this is usually where I get stuck. At this point, I have a master branch that is healthy and a new bug-fix-branch that contains my (untested -- other than unit tests) changes. If I want to push my changes to stage (through cap staging deploy), do I have to merge my changes back into the master branch (I'd prefer not to since it seems like master should be kept free of untested code)? Do I even deploy from master (or should I be tagging a release first and then modifying my production.rb file to deploy from that tag)? git-deployment seems to address some of these workflow issues, but I can't seem to find out how on earth it actually hooks into cap staging deploy and cap production deploy. Thoughts? I assume there's a likely canonical way to do this, but I either can't find it or I'm too new to git to recognize that I have found it. Help!

  • Fun with "The remote server returned an error: NotFound" - Silverlight4 Out of Browser

    - by Scott Silvi
    Hey all - I'm running SL4 on VS2010. I've got an app that authenticates via a web service to SPROC in my db. Unfortunately this is not WCF/WCF RIA, as I'm inheriting the DB/services from my client. This works perfectly inside of a browser. I'm attempting to move this OOB, and it's at this point that my authentication fails. Here's the steps I took... 1) SL App Properties Enable running app Out of Browser 2) SL App Properties Out of Browser Settings Require elevated trust when running OOB If i set a breakpoint on my logon button click, I see the service call is being made. However, if I step through it (or set a breakpoint on the actual logon web service), the code never gets that far. Here's the block it fails on: public LogonSVC.LogonResponse EndLogon(System.IAsyncResult result) { object[] _args = new object[0]; LogonSVC.LogonResponse _result = ((LogonSVC.LogonResponse)(base.EndInvoke("Logon", _args, result))); return _result; } I know using Elevated Trust means the crossdomain.xml isn't necessary. I dropped one in that allows everything, just to test, and that still fails. here's the code that calls the service: private void loginButton_Click(object sender, RoutedEventArgs e) { string Username = txtUserName.Text; string Password = txtPassword.Password; Uri iSilverlightServiceUriRelative = new Uri(App.Current.Host.Source, "../Services/Logon.asmx"); EndpointAddress iSilverlightServiceEndpoint = new EndpointAddress(iSilverlightServiceUriRelative); BasicHttpBinding iSilverlightServiceBinding = new BasicHttpBinding(BasicHttpSecurityMode.Transport);// Transport if it's HTTPS:// LogonService = new LogonSVC.LogonSoapClient(iSilverlightServiceBinding, iSilverlightServiceEndpoint); LogonService.LogonCompleted += new EventHandler<LogonSVC.LogonCompletedEventArgs>(LogonService_LogonCompleted); LogonService.LogonAsync(Username, Password); } My LogonService_LogonCompleted doesn't fire either (which makes sense, just a heads up). I don't know how to fiddler this, as this is running OOB with the site served via localhost/IIS. I know this works though in browser, so I'm curious what would break it OOB. Thank you, Scott

  • Minimal deployment of couchdb on windows

    - by MartinStettner
    Hi, I'd like to use couchdb for a client-only application on Windows (the document-oriented structure and the synchronization features would be perfect for me). There is a Windows installer package here, but the installer itself has about 45 MB, when installed it takes more than 100 MB on my HD. This is far to much for my (relatively small) application. I noticed that there are a lot of "src" directories in the couchdb/lib subdirs. I've been experimenting with removing some of them and it didn't seem to break the system. Now I'm wondering what would be the "minimal" set of files (preferably binary-only) that would be needed in order to run a local couchdb server. Are there already any efforts to create such a deployment-friendly installer? Or could anyone give some (even very general) hints how to create it? How much disk space would be minimally required for such an installation? Needless to say that I'm not at all familiar with neither the couchdb internals nor the Erlang system :). But perhaps I could figure out if I got some direction (or I could stop trying if someone told me that this would be impossible or didn't make sense at all ...) Thanks anyway!

  • Cannot convert object, recieved from ajax call, into a long

    - by Matt
    I'm using Asp.Net-Mvc, I have this method in my controller: [AcceptVerbs(HttpVerbs.Post)] public ActionResult LinkAccount(string site, object id) { return this.Json(id); } Here's the ajax method that calls it: $.post("/Account/LinkAccount", { site: "Facebook", id: FB.Facebook.apiClient.get_session().uid }, function(result) { alert(result); }, "json" ); returning this.Json(id); makes the alert work... it alerts 7128383 (something similar to that). but if I change this.Json(id) to this.Json(Conver.ToInt64(id)); the alert does not fire... Any idea of why I can't convert an object received from an object to a long? I already know changing the LinkAccount method to accept a long instead works just fine. It's just I need it as an object because some other sites I'm linking up have strings for id's rather than longs. UPDATE: I tried running the code on localhost so I could set a breakpoint. First I changed the line return this.Json(Convert.ToInt64(id)); to long idAsLong = Convert.ToInt64(id));. Here's what the debugger is telling me: When I hover over id it says: "id | {string[1]}" and when I press the plus button is shows: "[0] | '7128383'" When I hover over idAsLong, it says: "idAsLong | 0" Why isn't it converting it properly?

  • What's the best way to learn .NET?

    - by duffymo
    I've been developing Java EE for quite a while now. I've used WebLogic, Tomcat, Spring, and Hibernate extensively, so I have a mental model of what features are available and how things are developed and deployed. The problem that I have with .NET is that I don't have a clear mapping of its features onto Java EE. Here's what I know so far: Java EE - .NET Java - C# JAR - DLL WAR - ? (deployment in general) EAR - ? (deployment in general) Tomcat - IIS web server JSP - ASP? JDBC - ODBC JMS - MSMQ JTA - Microsoft Transaction Manager So much of the functionality that WebLogic handles appears to be dispersed throughout the Windows OS. My confusion kicks in when I see the waves of books at Borders - VB.NET, ASP.NET, C#, etc. If I'm not a VB programmer, would it be possible to stick with C# and write enterprise apps that are the equivalent of what I'm used to with Java EE? If there were a Top Three list of books to learn from, what would they be? The "Head First" series has certainly been successful for Java. http://www.amazon.com/Head-First-C-Brain-Friendly-Guides/dp/0596514824/ref=sr_1_1?ie=UTF8&s=books&qid=1224121193&sr=8-1 Equally well recommended for .NET learning? Thanks. - %

  • Dynamically adding radio buttons using JQUERY and then hooking up the jquery change event to the gen

    - by Barry
    i am adding collection of radio buttons to my page using jquery below $(document).ready(function() { $("#Search").click(function() { var keyword = $('#keyWord').val(); var EntityType = $("#lstEntityTypes :selected").text(); var postData = { type: EntityType, keyWord: keyword }; // alert(postData.VehicleType); $.post('/EntityLink/GetJsonEntitySearchResults', postData, function(GRdata) { var grid = '<table><tr><td>ID</td><td>Name</td><td></td>'; for (var i = 0; i < GRdata.length; i++) { grid += '<tr><td>'; grid += GRdata[i].ID; grid += '</td><td>'; grid += GRdata[i].EntityName; grid += '</td><td>'; grid += '<input type="radio" name="EntitiesRadio" value="' + GRdata[i].ID + '" />'; grid += '</td></tr>'; } grid += '</table>'; alert(grid); $("#EntitySearchResults").html(grid); $("EntitiesRadio").change(function() { alert($("EntitiesRadio :checked").val()); $("EntityID").val($("EntitiesRadio :checked").val()); alert($("EntityID").val()); $("EntityName").val($("#lstEntityTypes :selected").text()); }); }); }); // }); so when page loads there is not EntitiesRadio name range, so i tried to register the entitiesRadio change function inside the same search click method but it isnt registering. how do i get the change event to fire to update my hidden inputs

  • How to Read Device Data From serial port

    - by Aamir Khurshid
    I have one device which sends data on COM port say on COM13. Now i want to read that data and display it in the RichTextBox or in any text control. I have written the application with the help of IO and IO.Ports but comport.DataRecived event does not fire, even though device is sending data on that port. I have some software on which i define the port number and it successfully display data, which insure me that data is receiving on the Port but i am unable to receive. Is there any way i can read data? comm.Parity = cboParity.Text;//None comm.StopBits = cboStop.Text;//One comm.DataBits = cboData.Text;//8 comm.BaudRate = cboBaud.Text;//9600 comm.DisplayWindow = rtbDisplay;//Null comm.PortName = "COM13"; comm.OpenPort(); cmdOpen.Enabled = false; cmdClose.Enabled = true; cmdSend.Enabled = true; public bool OpenPort() { if (comPort.IsOpen) { comPort.Close(); } comPort.DataReceived += new SerialDataReceivedEventHandler(comPort_DataReceived); comPort.PortName = _portName; comPort.Open();return true; }

  • Two questions on ensuring EndInvoke() gets called on a list of IAsyncResult objects

    - by RobV
    So this question is regarding the .Net IAsyncResult design pattern and the necessity of calling EndInvoke as covered in this question Background I have some code where I'm firing off potentially many asynchronous calls to a particular function and then waiting for all these calls to finish before using EndInvoke() to get back all the results. Question 1 I don't know whether any of the calls has encountered an exception until I call EndInvoke() and in the event that an exception occurs in one of the calls the entire method should fail and the exception gets wrapped into an API specific exception and thrown upwards. So my first question is what's the best way then to ensure that the remainder of the async calls get properly terminated? Is a finally block which calls EndInvoke() on the remainder of the unterminated calls (and ignores any further exceptions) the best way to do this? Question 2 Secondly when I first fire off all my asyc calls I then call WaitHandle.WaitAll() on the array of WaitHandle instances that I've got from my IAsyncResult instances. The method which is firing all these async calls has a timeout to adhere to so I provide this to the WaitAll() method. Then I test whether all the calls have completed, if not then the timeout must have been reached so the method should also fail and throw another API specific exception. So my second question is what should I do in this case? I need to call EndInvoke() to terminate all these async calls before I throw the error but at the same time I don't want the code to get stuck since EndInvoke() is blocking. In theory at least if the WaitAll() call times out then all the async calls should themselves have timed out and thrown exceptions (thus completing the call) since they are also governed by a timeout but this timeout is potentially different from the main timeout

  • Submit form with JS

    - by Thomas
    Im working with a shopping cart plugin and that uses a basic form on the product page to submit values like price, product name, etc.. The problem is that the plugin uses a standard submit button to send the values and I would like to replace said button with a prettier custom jquery rollover. In order to make this happen I used some JS and tossed a link around my custom submit button: <a href="#" onclick="document.forms[0].submit()" value="Add to Cart" onsubmit="return ReadForm(this, true);"> <img class="fade" src="style/img/add_btn.jpg" style="background: url(style/img/add_ro.png);" alt=""/> </a> The form submits and the user is redirected to the homepage but the data in the form doesn't seem to get submitted and the product never gets added to the 'cart' page. I suspect that the form is getting submitted but I am failing to fire some additional JS function that submits the data. The plugin adds some JS to the top of the page: <!-- // function ReadForm (obj1, tst) { // Read the user form var i,j,pos; val_total="";val_combo=""; for (i=0; i<obj1.length; i++) { // run entire form obj = obj1.elements[i]; // a form element if (obj.type == "select-one") { // just selects if (obj.name == "quantity" || obj.name == "amount") continue; pos = obj.selectedIndex; // which option selected val = obj.options[pos].value; // selected value val_combo = val_combo + "(" + val + ")"; } } // Now summarize everything we have processed above val_total = obj1.product_tmp.value + val_combo; obj1.product.value = val_total; } //--> If you want to check out the the site in question, take a look here and click 'add to cart button': http://hardtopdepot.com/?p=34 You can see the cart at the top: http://hardtopdepot.com/?page_id=50 Any help would be super appreciated- thanks!

  • Custom pager in my Gridview 1st time works, next doesn't :

    - by gre3ns0ul
    Hi guys, i'm with one strange problem. I am extending a control from a Gridview, and adding a dropdown to paging to the page i want. In my custom gridview i added a ITemplate than contains 4 image buttons and one dropdownlist (4 images - 1st, prev, next, last) (1 ddl - to page) and add him to my custom gridview.. I added a selectindexchange event to dropdown, to fire when a index is changed The problem is: The first time i load the page with my control it is really ok.. but when i change index, in debug i see to run constructor of control, creating footer template, and guess.. the method of indexchange isn't fired and returns an exception saying: Unable to cast object of type 'System.Web.UI.WebControls.ImageButton' to type 'System.Web.UI.WebControls.Table'.

  • Declare module name of classes for logging

    - by Space_C0wb0y
    I currently am adding some features to our logging-library. One of these is the possibility to declare a module-name for a class that automatically gets preprended to any log-messages writing from within that class. However, if no module-name is provided, nothing is prepended. Currently I am using a trait-class that has a static function that returns the name. template< class T > struct ModuleNameTrait { static std::string Value() { return ""; } }; template< > struct ModuleNameTrait< Foo > { static std::string Value() { return "Foo"; } }; This class can be defined using a helper-macro. The drawback is, that the module-name has to be declared outside of the class. I would like this to be possible within the class. Also, I want to be able to remove all logging-code using a preprocessor directive. I know that using SFINAE one can check if a template argument has a certain member, but since other people, that are not as friendly with templates as I am, will have to maintain the code, I am looking for a much simpler solution. If there is none, I will stick with the traits approach. Thanks in advance!

  • How to use a loop to download HTML with paging?

    - by Nai
    I want to loop through this URL and download the HTML. https://www.googleapis.com/customsearch/v1?key=AIzaSyAAoPQprb6aAV-AfuVjoCdErKTiJHn-4uI&cx=017576662512468239146:omuauf_lfve&q=" + searchTermFormat + "&num=10" +"&start=" + i start and num controls the paging of the URL. So if &start=2, and &num=10, it will scrape 10 results from page 2. Given that Google has a max limit of num = 10, how can I write a loop that loops through the HTML and scrape the results for the first 10 pages? This is what I have so far which just scrapes the first page. //input search term Console.WriteLine("What is your search query?:"); string searchTerm = Console.ReadLine(); //concantenate the strings using + symbol to make it URL friendly for google string searchTermFormat = searchTerm.Replace(" ", "+"); //create a new instance of Webclient and use DownloadString method from the Webclient class to extract download html WebClient client = new WebClient(); int i = 1; string Json = client.DownloadString("https://www.googleapis.com/customsearch/v1?key=AIzaSyAAoPQprb6aAV-AfuVjoCdErKTiJHn-4uI&cx=017576662512468239146:omuauf_lfve&q=" + searchTermFormat + "&num=10" + "&start=" + i); //create a new instance of JavaScriptSerializer and deserialise the desired content JavaScriptSerializer js = new JavaScriptSerializer(); GoogleSearchResults results = js.Deserialize<GoogleSearchResults>(Json); //output results to console Console.WriteLine(js.Serialize(results)); Console.ReadLine();

  • Dynamic Control loading at wrong time?

    - by Telos
    This one is a little... odd. Basically I have a form I'm building using ASP.NET Dynamic Data, which is going to utilize several custom field templates. I've just added another field to the FormView, with it's own custom template, and the form is loading that control twice for no apparent reason. Worse yet, the first time it loads the template, the Row is not ready yet and I get the error message: {"Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."} I'm accessing the Row variable in a LinqDataSource OnSelected event in order to get the child object... Now for the wierd part: If I reorder the fields a little, the one causing the problem no longer gets loaded twice. Any thoughts? EDIT: I've noticed that Page_Load gets called on the first load (when Row throws an exception if you try to use it) but does NOT get called the second time around. If that helps any... Right now managing it by just catching and ignoring the exception, but still a little worried that things will break if I don't find the real cause. EDIT 2: I've traced the problem to using FindControl recursively to find other controls on the page. Apparently FindControl can cause the page lifecycle events (at least up to page_load) to fire... and this occurs before that page "should" be loading so it's dynamic data "stuff" isn't ready yet.

  • CompositeDataBoundControl - databound values overwritten before event is fired due to DummyDataSourc

    - by Vidar Langberget
    I have a custom servercontrol that inherits from CompositeDataBoundControl. I have three templates: one header template, one footer template and one item template. The item template can contain a checkbox that I use to decide if I should delete the item. In the footer and/or header templates I have a button with a CommandName of "DeleteItem". When that button is clicked, I handle the event in OnBubbleEvent: if (cea.CommandName == "DeleteItem") { //loop through the item list and get the selected rows List<int> itemsToDelete = new List<int>(); foreach(Control c in this.Controls){ if (c is ItemData) { ItemData oid = (ItemData)c; CheckBox chkSel = (CheckBox)oid.FindControl("chkSelected"); if (chkSel.Checked) { itemsToDelete.Add(oid.Item.Id); } } } foreach (int id in itemsToDelete) { DeleteItem(id); } } } The problem is that Item is null since the CreateChildControls method already has been run as asp.net needs to recreate the control hierarchy before the event fire. It uses the DummyDataSource and a list of null objects to recreate the control hierarchy: IEnumerator e = dataSource.GetEnumerator(); if (e != null) { while (e.MoveNext()) { ItemData container = new ItemData (e.Current as OrderItem); ITemplate itemTemplate = this.ItemTemplate; if (itemTemplate == null) { itemTemplate = new DefaultItemTemplate(); } itemTemplate.InstantiateIn(container); Controls.Add(container); if (dataBinding) { container.DataBind(); } counter++; } } The problem is this line: ItemData container = new ItemData (e.Current as OrderItem); When the control hierarchy is rebuilt before the event is fired, the e.Current is null, so when I try to find out which item was marked for deletion, I get 0 since the original value has been overwritten. Any suggestions on how to fix this?

  • Agile language for 2d game prototypes?

    - by instanceofTom
    Occasionally ( read: when my fiancé allows ) I like to prototype different game or game-like ideas I have. Usually I use Java or C# (not xna yet) because they are the languages I have the most practice with. However I would like to learn something more suited to agile development; a language in which it would be easier to knock out quick prototypes. At my job I have recently been working with looser (weak/dynamically typed) languages, specifically python and groovy, and I think something similar would fit what I am looking for. So, my question is: What languages (and framework/engine) would be good for rapidly developing prototypes of 2d game concepts? A few notes: I don't need blazing fast bitcrunching performance. In this case I would strongly prefer ease of development over performance. I'd like to use a language with a healthy community, which to me means a fair amount of maintained 3rd party, libraries. I'd like the language to be cross-platform friendly, I work on a variety of different operating systems and would like something that is portable with minimum effort. I can't imagine myself using a language with out decent options for debugging and editor syntax highlighting support. Note: If you are aware of a Java or C# library/framework that you think streamlines producing game prototypes I open to learning something new for those languages too

  • Given a main function and a cleanup function, how (canonically) do I return an exit status in Bash/Linux?

    - by Zac B
    Context: I have a bash script (a wrapper for other scripts, really), that does the following pseudocode: do a main function if the main function returns: $returncode = $? #most recent return code if the main function runs longer than a timeout: kill the main function $returncode = 140 #the semi-canonical "exceeded allowed wall clock time" status run a cleanup function if the cleanup function returns an error: #nonzero return code exit $? #exit the program with the status returned from the cleanup function else #cleanup was successful .... Question: What should happen after the last line? If the cleanup function was successful, but the main function was not, should my program return 0 (for the successful cleanup), or $returncode, which contains the (possibly nonzero and unsuccessful) return code of the main function? For a specific application, the answer would be easy: "it depends on what you need the script for." However, this is more of a general/canonical question (and if this is the wrong place for it, kill it with fire): in Bash (or Linux in general) programming, do you typically want to return the status that "means" something (i.e. $returncode) or do you ignore such subjectivities and simply return the code of the most recent function? This isn't Bash-specific: if I have a standalone executable of any kind, how, canonically should it behave in these cases? Obviously, this is somewhat debatable. Even if there is a system for these things, I'm sure that a lot of people ignore it. All the same, I'd like to know. Cheers!

  • Single intent to let user take picture OR pick image from gallery in Android

    - by Damian
    I'm developing an app for Android 2.1 upwards. I want to enable my users to select a profile picture within my app (I'm not using the contacts framework). The ideal solution would be to fire an intent that enables the user to select an image from the gallery, but if an appropriate image is not available then use the camera to take a picture (or vice-versa i.e. allow user to take picture but if they know they already have a suitable image already, let them drop into the gallery and pick said image). Currently I can do one or the other but not both. If I go directly into camera mode using MediaStore.ACTION_IMAGE_CAPTURE then there is no option to drop into the gallery. If I go directly to the gallery using Intent.ACTION_PICK then I can pick an image but if I click the camera button (in top right hand corner of gallery) then a new camera intent is fired. So, any picture that is taken is not returned directly to my application. (Sure you can press the back button to drop back into the gallery and select image from there but this is an extra unnecessary step and is not at all intuitive). So is there a way to combine both or am I going to have to offer a menu to do one or the other from within my application? Seems like it would be a common use case...surely I'm missing something?

  • DataReader already open when using LINQ

    - by Jamie Dixon
    I've got a static class containing a static field which makes reference to a wrapper object of a DataContext. The DataContext is basically generated by Visual Studio when we created a dbml file & contains methods for each of the stored procedures we have in the DB. Our class basically has a bunch of static methods that fire off each of these stored proc methods & then returns an array based on a LINQ query. Example: public static TwoFieldBarData[] GetAgesReportData(string pct) { return DataContext .BreakdownOfUsersByAge(Constants.USER_MEDICAL_PROFILE_KEY, pct) .Select(x => new TwoFieldBarData(x.DisplayName, x.LeftValue, x.RightValue, x.TotalCount)) .ToArray(); } Every now and then, we get the following error: There is already an open DataReader associated with this Command which must be closed firs This is happening intermittently and I'm curious as to what is going on. My guess is that when there's some lag between one method executing and the next one firing, it's locking up the DataContext and throwing the error. Could this be a case for wrapping each of the DataContext LINQ calls in a lock(){} to obtain exclusivity to that type and ensure other requests are queued?

  • Javascript ended event when video playback ends on android

    - by Tjofras
    I have been trying to create a web page that will redirect the user after he has watched a video (or if he aborted the playback). I've got this working on the iphone but can't really figure out how it works on the android. On the Iphone i have found two ways of doing this. using the tag to embed the quicktime plugin and then adding a event listener with javascript to listen to the 'qt_ended' event. This does obviously not work on android because there is no quicktime plugin. The second thing i tried was using the html5 -tag and listening to the 'ended' event, again this worked on the iphone but to my surprise not on android. In this case i got the video playing on the android phone but no redirect occurred after the video had reached the end. So my guess is that the android browser does not fully support the video-tag and that it does not fire the event. So at this time i don't really know how to proceed. I'm guessing i could do something similar to the quicktime embed solution but using a plugin available on android. But i cant find any information on what plugins is available on the android and if they support some kind of 'ended'-event.

  • Rewrite a URL that's already been redirected?

    - by Jack
    Hi guys, I'm running an Apache2 web server with a dynamic IP address. I bought exampledomain.net, and I use no-ip.com's domain-update service to redirect any visitors to my current ip address (endnote #1). For example, someone visits exampledomain.net and they get redirected to 73.181.57.34. It works like a charm. However, it isn't all that user-friendly. Can I rewrite the redirected, ip-address URL? I tried these rewrite rules in the root folder's .htaccess... RewriteEngine On RewriteCond %{HTTP_HOST} ^73\.181\.57\.34:88 RewriteRule ^(.*)$ http://www.exampledomain.net/$1 [L,NC] # I simplified the RewriteCond. I would use regex in a real situation. Of course, this creates an infinite loop. The user visits www.exampledomain.net. They're redirected to 73.181.57.34:88 by no-ip. Apache redirects them to www.exampledomain.net which redirects them back to 73.181.57.34:88... so on and so forth. I'm a noob when it comes to rewriting, but is there a way to rewrite a URL without redirecting? I tried these rewrite rules too (a shot in the dark)... RewriteEngine On RewriteCond %{HTTP_HOST} ^73\.181\.57\.34:88 RewriteRule ^(.*)$ my.exampledomain.net/$1 [L,NC] # I'd read that Apache replied with a redirect header when you include http Thanks! (1) No-IP works like this: You download and install their dynamic update client on your server. Every couple of minutes it polls your server for its current external ip address. If it's changed, it updates your server's ip address in no-ip's records.

  • IE8 claims my page has an error, firefox doesn't, and I can't find any error. Help!

    - by Bears will eat you
    This is something of a follow-up question to my question here. You can find the HTML source in a text file here. When I load that page in IE8, I get the "Done, but with errors on page." message in my status bar. The detail view shows Expected identifier sms Line: 147 Code: 0 Char: 67 and I see absolutely no problems anywhere near there. In IE8, the page is still behaving erratically w/r/t the randomly losing focus as mentioned in my other question. When I load the same exact page in Firefox (using Firebug) the console shows no errors and the page works perfectly. Any thoughts on what's going on here? This is driving me nuts and making me want to give up on even trying to write an IE friendly page. Edit: Thanks for all the comments! This page is written as a JSP, so I edit in Eclipse. I found an Eclipse warning about the onblur event for the username field. I switched it from onblur="alert(document.activeElement + ' class:' + document.activeElement.class)" to onblur="alert(document.activeElement)" and that made the bizarre IE page error vanish. I had been trying to give more info (namely, its CSS class) about specifically which element is stealing focus - to my own detriment, apparently, since Javascript was interpreting the '.class' part in the Java(script) sense. And, no, the page doesn't validate. But the errors were mostly/all ones that just didn't make sense, such as Line 14, Column 41: Attribute "LANGUAGE" is not a valid attribute. Did you mean "language"? to which I say, WTF?! But I'm still stuck trying to figure out why, as I enter text in the username & password fields, focus randomly switches to a div (working on figuring out which div currently). Edit 2: It's the div between the two "global nav" comments, at the very top of the body. Still no idea why it's happening, though.

  • ASP MVC - Routing Required?

    - by evo_9
    I've been reading up on MVC2 which came in VS2010 and it sounds pretty interesting. I'm actually in the middle of a large multi-tenant application project, and have just started coding the UI. I'm considering changing to MVC as I'm not that far along at this point. I have some questions about the Routing capabilities, namely are they required to use MVC or can I more or less ignore Routing? Or do I have to setup a default routing record that will make things work like standard ASPX (as far as routing alone is concerned)? The reason why I don't want to use Routing is because I've already defined a custom URL 'rewrite' mechanism of my own (which fires on session_start). In addition, I'm using jquery and opens-standards for the entire UI, and MVC's aspx overhead-free approach seems like a better fit based on how I've already started to build the application (I am not using viewstate at all, for example). I guess my big concern is whether the routing can be ignored, of if I will have to re-implement my custom URL rewriting to work with MVC, and if that's the case, how would I do that? As a new Routing routine, or stick with the session_start (if that's even possible?). Lastly, I don't want to use anything even remotely 'intelligent/readable' for the url - for a site like StackOverflow, the readability of the URL is a positive, but the opposite is true if it's not a public website like this one. In fact, it would seem to me that the more friendly MVC routing URL (which indirectly show method names) could pose a security risk on a private, non-public website app like I'm developing. For all these reasons I would love to use the lightweight aspects of MVC but skip the Routing entirely - is this possible?

  • Android AES and init vector

    - by Donald_W
    I have an issue with AES encryptio and decryption: I can change my IV entirely and still I'm able to decode my data. public static final byte[] IV = { 65, 1, 2, 23, 4, 5, 6, 7, 32, 21, 10, 11, 12, 13, 84, 45 }; public static final byte[] IV2 = { 65, 1, 2, 23, 45, 54, 61, 81, 32, 21, 10, 121, 12, 13, 84, 45 }; public static final byte[] KEY = { 0, 42, 2, 54, 4, 45, 6, 7, 65, 9, 54, 11, 12, 13, 60, 15 }; public static final byte[] KEY2 = { 0, 42, 2, 54, 43, 45, 16, 17, 65, 9, 54, 11, 12, 13, 60, 15 }; //public static final int BITS = 256; public static void test() { try { // encryption Cipher c = Cipher.getInstance("AES"); SecretKeySpec keySpec = new SecretKeySpec(KEY, "AES"); c.init(Cipher.ENCRYPT_MODE, keySpec, new IvParameterSpec(IV)); String s = "Secret message"; byte[] data = s.getBytes(); byte[] encrypted = c.doFinal(data); String encryptedStr = ""; for (int i = 0; i < encrypted.length; i++) encryptedStr += (char) encrypted[i]; //decryoption Cipher d_c = Cipher.getInstance("AES"); SecretKeySpec d_keySpec = new SecretKeySpec(KEY, "AES"); d_c.init(Cipher.DECRYPT_MODE, d_keySpec, new IvParameterSpec(IV2)); byte[] decrypted = d_c.doFinal(encrypted); String decryptedStr = ""; for (int i = 0; i < decrypted.length; i++) decryptedStr += (char) decrypted[i]; Log.d("", decryptedStr); } catch (Exception ex) { Log.d("", ex.getMessage()); } } Any ideas what I'm doing wrong? How can I get 256 bit AES encryption (only change key to 32-byte long array?) Encryption is a new topic for me so please for newbie friendly answers.

  • Updating ToolStripProgressBar and ToolStripStatusLabel along with with an action

    - by TChristian
    In a Windows Form, I have a search box that fires an event to search a remote database and display some results. The query is pretty fast, usually just a fraction of a second, but in case the delay is noticeable there is a progress bar and label in the form's status bar. When the user clicks "Search" the status label should appear and the progress bar show some progress. Then when the result comes back the label should disappear and the progress bar should be full. Pretty basic response. The problem is, I can't get those actions to happen in that order. Using the code below, I click "Search", nothing happens until the results are displayed, and then the progress bar fills up from 0 to 100. The label never appears. I even threw in a sleep command immediately after the event to be sure I wasn't just missing it, but it's as if the first 2 statements are not being executed. What am I doing wrong here? private void searchButton_Click(object sender, EventArgs e) { toolStripStatusLabel1.Visible = true; toolStripProgressBar1.Value = 20; m_changeRequestedEvents.Fire<String>("SearchTerm", searchTextBox.Text); toolStripProgressBar1.Value = 100; toolStripStatusLabel1.Visible = false; }
