  • SmartGWT alternatives

    - by Roger
    I have been using SmartGWT but have run into trouble mixing SmartGWT with other frameworks such as Wicket. Infact it has been a bit of a disaster and I regret going with it in the first place. I do not want this question to turn into any type of flame war, so therefore would just like people to list alternatives and their experience with those alternatives.

  • Naming lossless more appropriate

    - by LarsOn
    Starting just discussing the naming first ignoring tech details, lossless is a negative and double negative word for one good reason should get named more appropriate: Lossless also matches nothing. When naming like all intact or likewise matches something in a manner more physical like sounds are. Then more technically stated that a copy might contain more information than the original. Does method as such have a name, if so what do I refer to, can we name it if you please or just discuss related handling.

  • Nh.Burrow with WCF

    - by Jochen
    Hello, After implementing Nh.Burrow in an asp.net application, I was wondering how to do it for a WCF-service. My first idea was to put a the BurrowFramework().InitWorkSpace(); in each method and set the InstanceContextMode to per Call on these methods. Now I have two questions: Are there better methods to combine Nh.Burrow with WCF? Is there a way to create and use a Long Burrow Conversation with WCF? Regards, Jochen

  • Help with chat server

    - by mithun1538
    I am designing a chat server in java. The communication is Http based and not socket based. In the client side I have an applet. In the server side I have a servlet. Applet: I create a new thread to listen for incoming messages(GET method). The main thread is used to send messages(POST messages). The partial code is : public void start() { System.out.println("Creating new thread"); Thread thread = new Thread(this); thread.start(); } private String getNewMessage() { System.out.println("Inside getNewMessage"); String msg = null; try { while(msg == null) { System.out.println("Trying to listen to servlet"); URL servlet = new URL(getCodeBase(), "NewServlet?mode=msg"); URLConnection con = servlet.openConnection(); con.setUseCaches(false); DataInputStream din = new DataInputStream(new BufferedInputStream(con.getInputStream())); msg = din.readUTF(); System.out.println("message read :" + msg); } } catch (Exception e) { e.printStackTrace(); } return msg + "\n"; } public void run() { System.out.println("Inside new thread"); while(true) { System.out.println("inside first while"); String newMsg = getNewMessage(); chatOutput.append(newMsg); System.out.println("Appended!!"); } } private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) { String message = chatInput.getText(); chatInput.setText(""); chatOutput.append(message + "\n"); try { System.out.println("Trying to send msg :" + message); URL url = new URL(getCodeBase(), "NewServlet"); URLConnection servletConnection = url.openConnection(); servletConnection.setDoInput(true); servletConnection.setDoOutput(true); servletConnection.setUseCaches(false); servletConnection.setRequestProperty("Content-Type", "application/octet-stream"); ObjectOutputStream out = new ObjectOutputStream(servletConnection.getOutputStream()); out.writeObject(message); out.flush(); out.close(); System.out.println("Message sent!"); } catch (Exception e) { e.printStackTrace(); } } This next code is from the servlet side. it uses the Observable interface to identify and send messages to clients. public class NewServlet extends HttpServlet { // getNextMessage() returns the next new message. // It blocks until there is one. public String getNextMessage() { // Create a message sink to wait for a new message from the // message source. System.out.println("inside getNextMessage"); return new MessageSink().getNextMessage(source);} @Override protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { System.out.println("Inside Doget"); response.setContentType("text/plain"); PrintWriter out = response.getWriter(); out.println(getNextMessage()); } // broadcastMessage() informs all currently listening clients that there // is a new message. Causes all calls to getNextMessage() to unblock. public void broadcastMessage(String message) { // Send the message to all the HTTP-connected clients by giving the // message to the message source source.sendMessage(message); } @Override protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { System.out.println("Inside DoPost"); try { ObjectInputStream din= new ObjectInputStream(request.getInputStream()); String message = (String)din.readObject(); System.out.println("received msg"); if (message != null) broadcastMessage(message); System.out.println("Called broadcast"); // Set the status code to indicate there will be no response response.setStatus(response.SC_NO_CONTENT); } catch (Exception e) { e.printStackTrace(); } } /** * Returns a short description of the servlet. * @return a String containing servlet description */ @Override public String getServletInfo() { return "Short description"; } MessageSource source = new MessageSource();} class MessageSource extends Observable { public void sendMessage(String message) { System.out.println("inside sendMsg"); setChanged(); notifyObservers(message); } } class MessageSink implements Observer { String message = null; // set by update() and read by getNextMessage() // Called by the message source when it gets a new message synchronized public void update(Observable o, Object arg) { // Get the new message message = (String)arg; // Wake up our waiting thread notify(); } // Gets the next message sent out from the message source synchronized public String getNextMessage(MessageSource source) { // Tell source we want to be told about new messages source.addObserver(this); System.out.println("AddedObserver"); // Wait until our update() method receives a message while (message == null) { try { wait(); } catch (Exception ignored) { } } // Tell source to stop telling us about new messages source.deleteObserver(this); // Now return the message we received // But first set the message instance variable to null // so update() and getNextMessage() can be called again. String messageCopy = message; message = null; System.out.println("Returning msg"); return messageCopy; } } As you can see I have included System.out.println("Some message"); in some places. this was just for debugging purposes. In java console, i get the following output: Creating new thread Inside new thread. inside first while. Inside getNewMessage. Trying to listen to servlet. In the servlet side, i get the following output in the tomcat logs: Inside Doget. inside getNextMessage. AddedObserver. After i type a message in the applet, and send it, I get the foll output in java console: Trying to send msg :you deR?? Message sent! But in servlet side, I dont get anything in the logs. I used the O'Reily Java Servlet Programming as reference(The observer interface comes from there). But I am not getting any chat communication between two clients. As can be understood from the logs, the POST method is not called. Any reason for this?

  • Safari/Chrome problem with ajaxsubmit?

    - by Jan
    Hi I'm currently having some weird issues with ajaxsubmit (http://jquery.malsup.com/form/#ajaxSubmit), which I'm currently using in a project. I have a flow where I need to open a form into a modal window. I'm using fancybox for that and it works like a charm. When the form has been forced to open in the fancybox window there can happen two things. 1) If the user who is about to submit the form is logged in she should see a confirmation in the modal box, that her input was succesfully submitted 2)If the user is not logged in there should be loaded a login form once she hits the submit button 2.1) When the user has logged in she should receive a confirmation in the modal box. This is also working like a charm in Firefox, IE8 and IE7 but not in Safari or Chrome. The weird part is that it seems like safari and chrome are completely ignoring my ajaxsubmit form. To force the first form to be opened I use the follwoing script - this part is working in both Safari and Chrome. $(".klikEnPrisForm").ajaxForm({ success: function(data){ $.fancybox({'content':data}); } }); My ajaxsubmit form scrip looks like this var options = { url: '/?altTemplate=XmlProxyKlikEnPris', dataType: 'xml', data: $(this).serializeArray(), success: function(data) { if ($(data).find('loggetind').text() == 'true') { $("#klikenpris").hide(); $('<div id="fancybox-inner-klik"></div>').appendTo('#fancybox-inner'); $('#fancybox-inner-klik').load('/KlikEnPrisAccept?tilKvittering=1&sagsno=' + $(data).find('sagsnummer').text() + '&pris=' + $(data).find('pris').text() + '&klik-comment=' + $(data).find('kommentar').text() + '&klik-telefon=' + $(data).find('tlf').text() + '&klik-maeglerkontakt=' + $(data).find('maakontakte').text()).stop(true, true); } else { $("#klikenpris").hide(); $("#fancybox-wrap").css({ 'width': '480px', 'height': '220px' }); $("#fancybox-inner").css({ 'width': '460px', 'height': '220px' }); $('<div id="fancybox-inner-klik"></div>').appendTo('#fancybox-inner'); $('#fancybox-inner-klik').load('/login.aspx?loginklikpris=0&klikpris=1&sagsno=' + $(data).find('sagsnummer').text() + '&pris=' + $(data).find('pris').text() + '&klik-comment=' + $(data).find('kommentar').text() + '&klik-telefon=' + $(data).find('tlf').text() + '&klik-maeglerkontakt=' + $(data).find('maakontakte').text()).stop(true, true); } } }; // bind to the form's submit event $('#klikenprisform').submit(function() { // inside event callbacks 'this' is the DOM element so we first // wrap it in a jQuery object and then invoke ajaxSubmit $(this).ajaxSubmit(options); // !!! Important !!! // always return false to prevent standard browser submit and page navigation return false; }); I have tried inserting an alert in the succes callback function but it's never being called it seems. It seems like the default action is not being overruled by the link written in the "url" in ajaxsubmit. I'm really puzzled about this, since it's working nicely in other browsers and I'm completely lost on how I should approach the debugging in safari/chrome. I hope all the above makes sense and I'm looking forward to hear any suggestions. Cheers!

  • org-mode agenda tree view

    - by Ray
    In org-mode's daily/weekly agenda view, is there a way to display the full context of the entries? My reading of the code is that it finds the first heading above the timestamp and displays that. However, in my case, that heading is often 3-4 levels deep and doesn't make sense without the bullets above it. It also doesn't seem like there are hooks to easily change that. Filtering is trivial, but not changing the fundamental presentation format.

  • json problems with making a ruby on rails application

    - by Prince Merdz
    So I'm using Bitnami to learn Ruby on Rails. I have also previously tried the manual installation for ruby and rails and was met by the same problem so I thought I should try first the easy package deal of Bitnami. Anyway my problem with json is that it causes the bundle install to fail. First the auto bundle install that rails new does fails because of an ssl error. Which is easily solved by changing the source in the gemfile which is https to http. However when I try to bundle install it does another error when it tries to install json.

  • "Official" Way to deploy Assemblies into the GAC?

    - by Michael Stum
    I just wonder - if I need to deploy an assembly into the GAC, what is the "official" way of doing it? Currently we either manually drag/drop into the c:\windows\assembly folder or we use gacutil.exe. The first way is obviously not the good one (it's manual process after all), and gacutil is part of the SDK and not available per default on production servers. Are there any Microsoft deployment Guidelines?

  • Famous eponymous programming techniques

    - by Alicia
    In some sports certain techniques or elements are named after the athlete who invented or first performed them—for example, Biellmann spin. Is their widespread use of such names for programming techniques and idioms? What are they? To be clear, I am explicitly not asking about algorithms, which are quite often named after their creators. For example, one is Schwartzian transform, but I can't recall any more.

  • Will Python 3.0's backwards-incompatibility affect adoption?

    - by George Stocker
    I visited Slashdot this morning to find out that Python 3.0 has been released. I know C# and Perl, but have wanted to learn Python for some time, especially after I saw its ease of use to create useful tools, not to mention its use in game scripting. My question is, how does the intentionally backwards-incompatible release of Python 3.0 affect adoption, and should I learn Python 2? Or should I take the dive and learn Python 3.0 first, and wait for the libraries to be ported?

  • Converting Straight Quotes to Curly Quotes

    - by BlueVoid
    I have an application which uses a javascript based rules engine. I need a way to convert regular straight quotes into curl (or smart) quotes. It'd be easy to just do a string.replace for ["], only this will only insert one case of the curly quote. The best way I could think of was replace the first occurrence of a quote with a left curly quote and every other one following with a left, and the rest right curly. Is there a way to accomplish this using javascript?

  • Could MacRuby / HotCocoa supplant the need to know Objective-C?

    - by frou
    I just discovered MacRuby / HotCocoa and really like the sound of what they're doing. I had essentially discounted the prospect of making Cocoa GUI applications myself because I have an aversion to spending time & effort learning yet another C-based language, Objective-C. I'm not saying it's bad, just not for me. Is it the case now, or in the probable future, that one will be able to make Cocoa GUI applications of substantial and first-class nature with MacRuby / HotCocoa alone while ignoring Objective-C completely?

  • Taking screenshot with Win32 API (C# pInvoke) not working in IIS

    - by Dillen Meijboom
    I want to take a screenshot of an external website. Currently my workflow is to start a Firefox instance with the specified URL and take a screenshot using PrintWindow in the Win32 API When I run this application in IISExpress it works fine but when I run the same application in IIS on a windows VPS it is not working (screenshot is blank). I don't know what I'm doing wrong? My code: using Newtonsoft.Json; using System; using System.Collections.Generic; using System.Diagnostics; using System.Drawing; using System.Drawing.Imaging; using System.Linq; using System.Runtime.InteropServices; using System.Security; using System.Threading; using System.Web; namespace WebTools.Web { public class RemoteScreenshot { public static Bitmap TakeScreenshot(Process process) { // may need a process Refresh before return TakeScreenshot(process.MainWindowHandle); } public static Bitmap TakeScreenshot(IntPtr handle) { RECT rc = new RECT(); GetWindowRect(handle, ref rc); Bitmap bitmap = new Bitmap(rc.right - rc.left, rc.bottom - rc.top); using (Graphics graphics = Graphics.FromImage(bitmap)) { PrintWindow(handle, graphics.GetHdc(), 0); } return bitmap; } [DllImport("user32.dll")] private static extern bool GetWindowRect(IntPtr hWnd, ref RECT rect); [DllImport("user32.dll")] private static extern bool PrintWindow(IntPtr hWnd, IntPtr hDC, int flags); [StructLayout(LayoutKind.Sequential)] private struct RECT { public int left; public int top; public int right; public int bottom; } public static void Save(string url, string file, int timeout = 0) { Process.Start(new ProcessStartInfo("C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe", url) { CreateNoWindow = false, WindowStyle = ProcessWindowStyle.Maximized }); Thread.Sleep(timeout); var bitmap = TakeScreenshot(Process.GetProcessesByName("firefox").First()); bitmap.Save(file, ImageFormat.Png); bitmap.Dispose(); Process.GetProcessesByName("firefox").First().Kill(); } } } EDIT: Running Firefox works fine because the AppPool is under another account that has the rights to execute firefox.

  • resize ModalPopupExtender

    - by Joo Park
    after showing the ModalPopupExtender, there are two radio buttons that are displayed as part of the popup. When you select the second radio button, I display more information in a gridview control. When the ModalPopupExtender first displays, I have it set at 40% for width and height for the panel associated with the popup. After clicking the second radio button, I would like to resize the popup to 80% for width and height. My question is how do you resize ModalPopupExtender after it's initial popup?
