  • Viewing HTML inside Applet without using JEditorPane

    - by Tom
    Hello, I have a small (500kb) swing applet that displays very simple/limited set of small HTML page(s) inside it with JEditorPane, however this does not seem to work 100% fluently, some customers get a blank page displayed without any java exceptions. The page works OK from my machine. I need a more reliable way to show HTML page to all our users. Any ideas if there is a small + free class to use instead of JEditorPane OR is there an easy fix to make it more reliable (non blank) private JEditorPane m_editorPane = new JTextPane(); m_editorPane.setEditable( false); m_editorPane.setBackground(new Color(239 ,255, 215)); m_editorPane.setBounds(30,42,520,478 ); m_editorPane.setDoubleBuffered(true); m_editorPane.setBorder(null); m_editorPane.registerEditorKitForContentType("text/html", "com.xxxxx.SynchronousHTMLEditorKit"); m_editorPane.setPage(ResourceLoader.getURLforDataFile(param.trim()));

    - by Stacey
    I'm trying to return a json result from a jQuery Form instance - but it keeps prompting me to download a file instead of displaying it in the window like it is supposed to... $("#ajaxImageForm").ajaxForm({ iframe: true, type: "GET", dataType: "json", beforeSubmit: function() { $("#ajaxImageForm").block({ message: '<img src="/content/images/loader.gif" /> Uploading . . .' }); }, success: function(result) { $("#ajaxImageForm").unblock(); $.growlUI(null, result.message); } }); [AcceptVerbs(HttpVerbs.Post)] public JsonResult Edit(FormCollection collection) { // return Json to the jQuery Form Result return new JsonResult { Data = new { message = string.Format("edited successfully.") } }; }

  • OnmouseMove not work with SetTimeOut and Alerts in Chome

    - by Diogo Fernandes
    What's wrong with this code? It works in IE and FireFox, but Chrome does not work. The idea is that the function fnTimeOut will be triggered in 5 seconds after onmousemove. It´s ok. But when, in Chrome, I click on the button "ok" to function fnAlert is triggered instantly. It should be shot just 5 seconds after I move the mouse ... help me please. <input type="button" onclick="alert(1);" value="ok"> <script> document.onmousemove = fnTimeOut; var t = null; function fnAlert() { alert(2); } function fnTimeOut() { clearTimeout( t ); t = setTimeout( fnAlert, 5000 ); } </script>

  • LinkedList cannot be serialised?

    - by iTayb
    Here are my classes: http://pastebin.com/3dc5Vb1t When I try to run BookStore b = new BookStore(); b.LoadFromXML(Server.MapPath("list.xml")); Label1.Text = b.ToString(); I get the following error: You must implement a default accessor on System.Collections.Generic.LinkedList`1[[Book, App_Code.cxsacizw, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null]] because it inherits from ICollection. The error source is XmlSerializer s = new XmlSerializer(typeof(BookStore)); When I tried to look for a solution on google, I found it that LinkedList has some problems with serialization. How can I deal with it? Thank you very much.

  • XML output from MySQL

    - by NumberFour
    Hi, is there any chance of getting the output from a MySQL query directly to XML? Im referring to something like MSSQL has with SQL-XML plugin, for example: SELECT * FROM table WHERE 1 FOR XML AUTO returns text (or xml data type in MSSQL to be precise) which contains an XML markup structure generated according to the columns in the table. With SQL-XML there is also an option of explicitly defining the output XML structure like this: SELECT 1 AS tag, NULL AS parent, emp_id AS [employee!1!emp_id], cust_id AS [customer!2!cust_id], region AS [customer!2!region] FROM table FOR XML EXPLICIT which generates an XML code as follows: <employee emp_id='129'> <customer cust_id='107' region='Eastern'/> </employee> Do you have any clues how to achieve this in MySQL? Thanks in advance for your answers.

  • Confused about this factory, as it doesn't look like an Abstract Factory nor Factory Method

    - by Pin
    I'm looking into Guice and I've been reading its documentation recently. Reading the motivation section I don't understand the factories part, why they name it that way. To me that factory is just a wrapper for the implementing class they want it to return after calling getInstance(). public class CreditCardProcessorFactory { private static CreditCardProcessor instance; public static void setInstance(CreditCardProcessor creditCardProcessor) { instance = creditCardProcessor; } public static CreditCardProcessor getInstance() { if (instance == null) { throw new IllegalStateException("CreditCardProcessorFactory not initialized. " + "Did you forget to call CreditCardProcessor.setInstance() ?"); } return instance; } } Why do they call it factory as well if it is neither an abstract factory nor a factory method? Or am I missing something? Thanks.

  • HttpWebRequest is extremely slow!

    - by Earlz
    Hello, I am using an open source library to connect to my webserver. I was concerned that the webserver was going extremely slow and then I tried doing a simple test in Ruby and I got these results Ruby program: 2.11seconds for 100 HTTP GETs C# library: 20.81seconds for 100 HTTP GETs I have profiled and found the problem to be this function: private HttpWebResponse GetRawResponse(HttpWebRequest request) { HttpWebResponse raw = null; try { raw = (HttpWebResponse)request.GetResponse(); //This line! } catch (WebException ex) { if (ex.Response is HttpWebResponse) { raw = ex.Response as HttpWebResponse; } } return raw; } The marked line is takes over 1 second to complete by itself while the ruby program making 1 request takes .3 seconds. I am also doing all of these tests on 127.0.0.1, so network bandwidth is not an issue. What could be causing this huge slow down?

  • Strlen of MAX 16 chars string using bitwise operators

    - by fabrizioM
    The challenge is to find the fastest way to determine in C/C++ the length of a c-string using bitwise operations in C. char thestring[16]; The c-string has a max size of 16 chars and is inside a buffer If the string is equal to 16 chars doesn't have the null byte at the end. I am sure can be done but didn't got it right yet. I am working on this at the moment, but assuming the string is memcpied on a zero-filled buffer. len = buff[0] != 0x0 + buff[1] != 0x0 + buff[2] != 0x0 + buff[3] != 0x0 + buff[4] != 0x0 + buff[5] != 0x0 + buff[6] != 0x0 + buff[7] != 0x0 + buff[8] != 0x0 + buff[9] != 0x0 + buff[10] != 0x0 + buff[11] != 0x0 + buff[12] != 0x0 + buff[13] != 0x0 + buff[14] != 0x0 + buff[15] != 0x0;

  • Validate a belongs to association in a build situation.

    - by Victor Martins
    I have a Mission model that has_many Task, and the Task belongs_to Mission For security I've made this validation on the Task Model: validates_presence_of :mission_id validates_numericality_of :mission_id But the problem is that when create a Mission and add tasks like this: @mission.tasks.build The validation returns error, because the mission id on the task is null ( the mission wasn't yet created ) If I delete the validation, the Mission and Task is created successfuly, but how can I keep the validation and still have this work? I could do a callback after the save, but I don't think that's right, because I don't want to save Tasks without a mission_id. P.S. I'm hidding my mission field on the form. If I have it visible, it will show the currect mission and everything is ok. But if I hidde it the error happens. <%= f.hidden_field :mission, :label => "Missão" %> Is the form reseting the attributes given by the controller on the new action?

  • Account preferences crashes on ListPreference

    I have created an account type using the AccountAuthenticator stuff as done in the SampleSyncAdapter tutorial. I am now trying to get account preferences working. I have added the line android:accountPreferences="@xml/account_preferences" to my account-authenticator and account_preferences.xml looks like so: <?xml version="1.0" encoding="utf-8"?> <PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"> <PreferenceCategory android:title="@string/alum_settings_title"/> <CheckBoxPreference android:key="sync_alum" android:title="@string/sync_alum" android:summaryOn="@string/sync_alum_check" android:summaryOff="@string/sync_alum_nocheck"/> <ListPreference android:key="sync_alum_since" android:title="@string/alum_years" android:entries="@array/years" android:entryValues="@array/years" android:dependency="sync_alum"/> </PreferenceScreen> The checkbox preference works exactly like it should but the ListPreference crashes the entire system with the following message: 05-14 22:32:16.794: ERROR/AndroidRuntime(63): android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application I get the same error with EditTextPreference and with the custom subclass of DialogPreference I created.

  • linq Except and custom IEqualityComparer

    - by Joe
    I'm trying to implement a custom comparer on two lists of strings and use the .Except() linq method to get those that aren't one one of the lists. The reason I'm doing a custom comparer is because I need to do a "fuzzy" compare, i.e. one string on one list could be embedded inside a string on the other list. I've made the following comparer ` public class ItemFuzzyMatchComparer : IEqualityComparer { bool IEqualityComparer<string>.Equals(string x, string y) { return (x.Contains(y) || y.Contains(x)); } int IEqualityComparer<string>.GetHashCode(string obj) { if (Object.ReferenceEquals(obj, null)) return 0; return obj.GetHashCode(); } } ` When I debug, the only breakpoint that hits is in the GetHashCode() method. The Equals() never gets touched. Any ideas?

  • How to create a custom yaml config file in Symfony

    - by Guillaume Flandre
    What I want to do is quite simple: store data in a custom config file that I want to read later on. I created my file something.yml that I put in the global config directory. It looks like that: prod: test: ok dev: test: ko all: foo: bar john: doe Then I copied the config_handlers.yml and also put it in the config directory and added the following at the top of the file: config/something.yml: class: sfDefineEnvironmentConfigHandler param: prefix: something_ But if I'm calling sfConfig::get("something_foo"); I keep getting NULL. What did I do wrong? I just want to read values, so no need to create a custome config handler, right? I've read the doc here: http://www.symfony-project.org/book/1_2/19-Mastering-Symfony-s-Configuration-Files even though I'm running 1.4 (I don't think that changed since then). Edit: Of course I can use sfYaml::load() but I'd like to do things in a better way.

  • Resetting or refreshing a database connection

    - by cdonner
    This Android application on Google uses the following method to refresh the database after replacing the database file with a backup: public void resetDbConnection() { this.cleanup(); this.db = SQLiteDatabase.openDatabase( "/data/data/com.totsp.bookworm/databases/bookworm.db", null, SQLiteDatabase.OPEN_READWRITE); } I did not build this app, and I am not sure what happens. I am trying to make this idea work in my own application, but the data appears to be cached by the views, and the app continues to show data from the database that was replaced, even after I call cleanup() and reopen the database. I have to terminate and restart the activity in order to see the new data. I tried to call invalidate on my TabHost view, which pretty much contains everything. I thought that the views would redraw and refresh their underlying data, but this did also not have the expected result. I ended up restarting the activity programmatically, which works, but this seems to be a drastic measure. Is there a better way?

  • IE8 AJAX GET setRequestHeaders not working unless params provided in URL

    - by bobthabuilda
    I'm trying to create an AJAX request in IE8. var xhr = new ActiveXObject( 'Msxml2.XMLHTTP' ); xhr.open( 'GET', '/ajax/' ); // Required header for Django to detect AJAX request xhr.setRequestHeader( 'X-Requested-With', 'XMLHttpRequest' ); xhr.onreadystatechange = function() { if ( this.readyState == 4 ) console.log(this.responseText); } xhr.send( null ); This works perfectly fine in Firefox, Chrome, Safari. In IE8 however, all of my AJAX test requests work EXCEPT for ones where I'm performing GETs without any query string params (such as the one above). POSTs work without question, and GET requests only work whenever I include query strings in the URL, like this: xhr.open( 'GET', '/ajax/?foo=bar' ) I'm also 110% positive that my server code is handling these requests appropriately, so, this stumps me completely. Does anyone have any clue as to what might be causing this?

  • How GC collects resources in a static member in C#?

    - by carter-boater
    Dear all, I have a piece of code like this: Class Program { static StreamReader sr = null; static int var=0; static Program() { sr = new StreamReader("input.txt") } ~Program() { sr.Dispose(); } static void main(string args[]) { //do something with input here } } This may not be a good practice, but I just want to use this example to ask how the deconstructor and GC works. My question is: Will ~Program() get called at a non-determined time or it won't be called at all in this case. If the deconstructor won't get called, then how GC collect the unmanaged resources and managed resources. Thank you very much!

  • How does Entity Framework 4.0 determine which parameters are required for the factory method of an e

    - by Scott Davies
    Hi, I am working with Entity Framework 4.0 (VS 2010 Beta 2, NOT RC). I can model the EDM and produce the required database. When I ask VS to generate the code for the model, it generates the expected .designer.cs file. When I look at the factory methods for each entity that the designer has generated, I've noticed that it doesn't include all of the properties of the entity. Is it correct to say that the factory method only includes properties that cannot be null ? This appears to be the case, but I'm not entirely sure. Thanks, Scott

  • Ensure a new session every time the user connects to a Servlet

    - by Daziplqa
    Hi, I've a JSP/Servlet Web App that consist of more than one servlet (and some JSPs) I need to create an new HttpSession whenever the users access servlet A, knowing that, servlet A is the home page (i.e. he access it as the first servlet/page in the application) so far so good, I can write the following code at the start of the servlet A: HttpSession session = request.getSession(false); if (session == null) { logger.debug("starting new session..."); session = request.getSession(); // other staff here } But the problem is, if the user didn't close his browser (even if he closes the tab - in firefox for instance - the session will still be open), so when he try to open my site again, the last session will be re-used (in the rage of session timeout ofcourse), and this I don't need. I need whenever he access Servlet A, he got created a brand new HttpSession. but unfortunately, he may access this servlet twice per session based on some scenario!! Please help.
