• Does flex not support hashmaps?

  - by Dr.Dredel

  I have a Flex object which collects a DTO from the server. All the fields arrive filled in correctly except for the one that is a HashMap. It arrives as null. I've tried giving it a type of both ArrayCollection and Dictionary, but that hasn't fixed it. Does anyone know if there's an inherent incomaptability between Java HashMap and Flex? If not, what might I be doing wrong here? I'm looking at my jboss console and I see the data being populated correctly in the server side before delivery to the client. However, as it gets to the client, that field is null. I'm ready to kill myself.

• Which free PHP based forum is the easiest to extend or customize? [closed]

  - by aditya menon

  Possible Duplicate: Which Content Management System (CMS) should I use? I am looking to start a new forum, with a traditional forum layout (like webhostingtalk, for example). In this space, I know phpBB and SMF are strong contenders. I do not know for sure the names of other great forum software that might exist... My most important need is that it should be easy to modify the display area, at the least, without having to dig too much into the core. Drupal excels in this area with its templating system, but the forum module doesn't look like the forum interface most people are used to... It would be a great plus if the software has alternative Captchas like question based or invisible Captcha. If it doesn't, I would like to be able to code it in without much trouble (that is, the software exposes a good API)

• JQuery never reaches success or fail on aspx returning json.

  - by David

  Basicaly I have my aspx page doing <% Response.Clear(); Response.Write("{\"Success\": \"true\" }"); Response.End(); %> My JQuery code is function DoSubmit(r) { if (r == null || r.length == 0 || formdata == null || formdata.length == 0) return; for (i = 0; i < formdata.length; i++) { var fd = formdata[i]; r[fd.Name] = fd.Value; } r["ModSeq"] = tblDef.ModSeq; jQuery.ajax({ url: "NashcoUpdate.aspx" , succsess: doRow , error: DoSubmitError , complete: DoSubmitComplete , dataType: "json" , cache: false , data: r , type: "post" }) } When I call the DoSubmit() function every thing works but the doRow or DoSubmitError functions never get called only the DoSubmitComplete function. When I look at the response text in teh DoSubmitComple function it is {"Success": "true" } Every JSON tester I have tried says that this is valied JSON. What am I doing wrong here?

• What's the diffrence btw System property and system environment variable

  - by khue

  Hi all I am not clear about this. When I run a java App or run an Applet in applet viewer,( in the IDE environment), System.getProperty("java.class.path") give me the same as System.getenv("CLASSPATH"), which is the CLASSPATH env variable defined. But when I deploy my applet to webserver and access it from the same computer as a client, I get different result for the two (System.getProperty("java.class.path") only point to jre home and System.getenv("CLASSPATH") return null). And here is some other things that make me wonder: For the applet part, the env var JAVA_HOME, i get the same result when deploying the applet in a browser as well as Applet Viewer. And if I define myself a env variable at system level, and use getenv("envName") the result is null. Is there anyway I can define one and get it in my java program? Thanks a lot Regards K.

• Model Binding using ASP.NET MVC, getting datainput to the controller.

  - by Calibre2010

  Pretty Basic one here guys. I have a View which holds 2 textfields for input and a submit button <%using (Html.BeginForm("DateRetrival", "Home", FormMethod.Post)){ %> <%=Html.TextBox("sday")%> <%=Html.TextBox("eday")%> <input type="submit" value="ok" id="run"/> <% }%> the following controller action which I want to bind the data input is as follows [AcceptVerbs(HttpVerbs.Get)] public ActionResult DateRetrival() { return View(); } [AcceptVerbs(HttpVerbs.Post)] public ActionResult DateRetrival(string submit) { return null; } When I debug this and look in the action methods parameter, the value is null. When I've entered values in both textboxes and and clicked the submit method.

• Blogger Dynamic template sometimes broken

  - by ber4444

  In all browsers (IE, Chrome, etc.) in my office and in all Blogger blogs using the dynamic template, I'm having this strange problem: No menu on the right side (except for the Subscribe button - other buttons are missing) plus no layout selection bar (top row). This problem is occasional, not happening reliably; any ideas? Update: whenever I get the menu problem with dynamic templates, I also seem to get a broken page (in Chrome, IE, etc) with simple templates - see second screenshot. Does anyone having this issue?

• Web service can't open named pipe - access denied

  - by Patrick

  Hi All, I've got a C++ service which provides a named pipe to clients with a NULL SECURITY_ATTRIBUTES as follows: hPipe = CreateNamedPipe( lpszPipename, PIPE_ACCESS_DUPLEX | FILE_FLAG_OVERLAPPED, PIPE_TYPE_BYTE | PIPE_READMODE_BYTE | PIPE_WAIT, PIPE_UNLIMITED_INSTANCES, BUFSIZE, BUFSIZE, 0, NULL); There is a dll which uses this pipe to get services. There is a c# GUI which uses the dll and works fine. There is a .net web site which also uses this dll (the exact same one on the same PC) but always gets permission denied when it tries to open the pipe. Any one know why this might happen and how to fix it? Also does anyone know of a good tutorial on SECURITY_ATTRIBUTES because I haven't understood the msdn info yet. Thanks, Patrick

• How can I make these images download on a separate thread?

  - by Andy Barlow

  I have the following code running on my Android device. It works great and displays my list items wonderfully. It's also clever in the fact it only downloads the data when it's needed by the ArrayAdapter. However, whilst the download of the thumbnail is occurring, the entire list stalls and you cannot scroll until it's finished downloading. Is there any way of threading this so it'll still scroll happily, maybe show a place holder for the downloading image, finish the download, and then show? Any help with this would be really appreciated. private class CatalogAdapter extends ArrayAdapter<SingleQueueResult> { private ArrayList<SingleQueueResult> items; //Must research what this actually does! public CatalogAdapter(Context context, int textViewResourceId, ArrayList<SingleQueueResult> items) { super(context, textViewResourceId, items); this.items = items; } /** This overrides the getview of the ArrayAdapter. It should send back our new custom rows for the list */ @Override public View getView(int position, View convertView, ViewGroup parent) { View v = convertView; if (v == null) { LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE); v = vi.inflate(R.layout.mylists_rows, null); } final SingleQueueResult result = items.get(position); // Sets the text inside the rows as they are scrolled by! if (result != null) { TextView title = (TextView)v.findViewById(R.id.mylist_title); TextView format = (TextView)v.findViewById(R.id.mylist_format); title.setText(result.getTitle()); format.setText(result.getThumbnail()); // Download Images ImageView myImageView = (ImageView)v.findViewById(R.id.mylist_thumbnail); downloadImage(result.getThumbnail(), myImageView); } return v; } } // This should run in a seperate thread public void downloadImage(String imageUrl, ImageView myImageView) { try { url = new URL(imageUrl); URLConnection conn = url.openConnection(); conn.connect(); InputStream is = conn.getInputStream(); BufferedInputStream bis = new BufferedInputStream(is); Bitmap bm = BitmapFactory.decodeStream(bis); bis.close(); is.close(); myImageView.setImageBitmap(bm); } catch (IOException e) { /* Reset to Default image on any error. */ //this.myImageView.setImageDrawable(getResources().getDrawable(R.drawable.default)); } }

• XML validation in Java - why does this fail?

  - by jd

  hi, first time dealing with xml, so please be patient. the code below is probably evil in a million ways (I'd be very happy to hear about all of them), but the main problem is of course that it doesn't work :-) public class Test { private static final String JSDL_SCHEMA_URL = "http://schemas.ggf.org/jsdl/2005/11/jsdl"; private static final String JSDL_POSIX_APPLICATION_SCHEMA_URL = "http://schemas.ggf.org/jsdl/2005/11/jsdl-posix"; public static void main(String[] args) { System.out.println(Test.createJSDLDescription("/bin/echo", "hello world")); } private static String createJSDLDescription(String execName, String args) { Document jsdlJobDefinitionDocument = getJSDLJobDefinitionDocument(); String xmlString = null; // create the elements Element jobDescription = jsdlJobDefinitionDocument.createElement("JobDescription"); Element application = jsdlJobDefinitionDocument.createElement("Application"); Element posixApplication = jsdlJobDefinitionDocument.createElementNS(JSDL_POSIX_APPLICATION_SCHEMA_URL, "POSIXApplication"); Element executable = jsdlJobDefinitionDocument.createElement("Executable"); executable.setTextContent(execName); Element argument = jsdlJobDefinitionDocument.createElement("Argument"); argument.setTextContent(args); //join them into a tree posixApplication.appendChild(executable); posixApplication.appendChild(argument); application.appendChild(posixApplication); jobDescription.appendChild(application); jsdlJobDefinitionDocument.getDocumentElement().appendChild(jobDescription); DOMSource source = new DOMSource(jsdlJobDefinitionDocument); validateXML(source); try { Transformer transformer = TransformerFactory.newInstance().newTransformer(); transformer.setOutputProperty(OutputKeys.INDENT, "yes"); StreamResult result = new StreamResult(new StringWriter()); transformer.transform(source, result); xmlString = result.getWriter().toString(); } catch (Exception e) { e.printStackTrace(); } return xmlString; } private static Document getJSDLJobDefinitionDocument() { DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); DocumentBuilder builder = null; try { builder = factory.newDocumentBuilder(); } catch (Exception e) { e.printStackTrace(); } DOMImplementation domImpl = builder.getDOMImplementation(); Document theDocument = domImpl.createDocument(JSDL_SCHEMA_URL, "JobDefinition", null); return theDocument; } private static void validateXML(DOMSource source) { try { URL schemaFile = new URL(JSDL_SCHEMA_URL); Sche maFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI); Schema schema = schemaFactory.newSchema(schemaFile); Validator validator = schema.newValidator(); DOMResult result = new DOMResult(); validator.validate(source, result); System.out.println("is valid"); } catch (Exception e) { e.printStackTrace(); } } } it spits out a somewhat odd message: org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid content was found starting with element 'JobDescription'. One of '{"http://schemas.ggf.org/jsdl/2005/11/jsdl":JobDescription}' is expected. Where am I going wrong here? Thanks a lot

• Synchronizing reading and writing with synchronous NamedPipes

  - by Mike Trader

  A Named Pipe Server is created with hPipe = CreateNamedPipe( zPipePath, PIPE_ACCESS_DUPLEX, PIPE_TYPE_BYTE | PIPE_WAIT | PIPE_READMODE_BYTE, PIPE_UNLIMITED_INSTANCES, 8192, 8192, NMPWAIT_USE_DEFAULT_WAIT, NULL) Then we immediately call: ConnectNamedPipe( hPipe, BYVAL %NULL ) Which blocks until the client connects. Then we proceed directly to ReadFile( hPipe, ... The problem is that it takes the Client takes a finite amount of time to prepare and write all the fcgi request parameters. This has usually not completed before the Pipe Server performs its ReadFile(). The Read file operation thus finds no data in the pipe and the process fails. Is there a mechanism to tell when a Write() has occurred/finished after a client has connected to a NamedPipe? If I had control of the Client process, I could use a common Mutex, but I don't, and I really do not want to get into I/O completion ports just to solve this problem! I can of course use a simple timer to wait 60m/s or so which is usually plenty of time for the wrote to complete, but that is a horrible hack.

• MVC actionlink posting List of complex type

  - by Ying

  I have an actionlink that on click im passing a List of objects to a controller action. Example: View: Html.ActionLink("TestLink", "TestMethod", "Test", Model.SampleList, null) TestController: public ActionResult TestMethod(List sampleList) { return View(sampleList); } When I do this I get a null sampleList. I can pass a single complex object fine just not a collection of it. Do I need the correct routing for this? The reason I'm doing this is instead of passing an id and do a look up in the controller action, I just pass in the data.

• Accessing Content Page elements

  - by Abdel Olakara

  Hi all, I am facing a strange problem.. may be i am overlooking something and not able to find the silly issue. Need your help! I have a Master page and a Content Page: <form id="AccountForm" runat="server"> <div> <asp:ContentPlaceHolder ID="MenuHolder" runat="server"> </asp:ContentPlaceHolder> </div> <hr /> <div> <asp:ContentPlaceHolder ID="ContentHolder" runat="server"> </asp:ContentPlaceHolder> </div> And my content page has some form elements: <asp:Content ID="Content3" ContentPlaceHolderID="ContentHolder" runat="server"> First Name: <asp:TextBox ID="fName" runat="server"></asp:TextBox> <br /> Middle Name: <asp:TextBox ID="mName" runat="server"></asp:TextBox> <br /> Family Name: <asp:TextBox ID="lName" runat="server"></asp:TextBox> <br /> Birthday: <asp:TextBox ID="birthday" runat="server"></asp:TextBox> <br /> Mobile Phone: <asp:TextBox ID="mobile" runat="server"></asp:TextBox> <br /> Alternate Phone: <asp:TextBox ID="phone" runat="server"></asp:TextBox> <br /> I also have the code for submit button in the content page where i try to retrieve the values from the form elements and persist it into DB.

Their objects are not null as well!! why is this behaviour happening? I am not trying to access elements in master page or other.. all the fields are in the content page.. only thing is there is no form element in the content page and the form element is in master page!

This is often an indication that other memory is corrupt. The catch that is in C# code doesn't actually catch it. Why? How to handle this exception? Thank you for your help!

My question is whether there is an easy way to make Hibernate to just ignore inserts which would in effect insert duplicates?

• Directory paths for resources and assets

  - by The Communist Duck

  If I have a file stucture for my final, released game something like: Main folder Media Images Other assets Sounds Executable List item And a different one for my 'in development' project, with the same Media folder but: Main Source and .obj, etc. Media with everything Bin folder with executable I obviously cannot hardcode file pathnames into this, like: "../Media/Image/evilguy.png" or "Media/Image/foo.jpg" because they wouldn't work with one of the builds and would require a lot of switching names. Instead, does it make sense for my resource manager, that loads everything, to have some kind of prefix path? Then, I can just do Get("foo.jpg") or Get("Sounds/boom.ogg") And simply switch out, for the final release, the ctr argument from the relative path for the development build to the release layout? If not, how have other people sorted these sorts of things out?

• CMS without templates

  - by Mark

  I am looking for a CMS where I can layout the page from scratch using HTML/PHP/CSS and simply enter code such as:- FOR EACH (listOfArticles) SORT mostRecent CATEGORY news LIMIT 5 <div class="articleTitle">{title}</div> <div class="arcielBody">{body}</div> END to get a list of the five most recent articles of a certain category in the relevant place. Does such a thing exist anymore? Unless my mind is playing tricks on me, the CMSs of five or ten years ago had this approach. I am thinking of MovableType and the now defunct CityDesk. It seems to me that CMSs these days have a 'templates first' approach. I.E. you must always choose a template before doing anything - which I find really painful. Learning how to design these structured templates also seems overly painful. So can anyone help me in my quest? Thank you, Mark

• Sessionstate not being saved between pages

  - by Grant

  Hi, i am having problems with an asp.net c# site whereby i am setting a session state object to true and then redirecting to another page that needs to check the value of the session state object and it is null. Sometimes it is set correctly and other times is is simply null. When i debug on my local machine it works perfectly every time. Only when i upload to my web server does this temperamental behaviour happen. As it is based around the security of the site it is obviously important that the session data be valid and accurate every time. Is session state data unreliable? AFAIK its set to inproc, cookieless, 30 min timeout, vanilla installation of IIS. Does anyone have any suggestions? Perhaps i need to thread.sleep inbetween the storing of the session data and the reading? NB: the time between the write and the read is about 70ms.. ample time for the data to be written to RAM.....

• Telerik RadAjaxManager and Mouse Events in Chrome

  - by kuzco

  Whenever I'm using Telerik's RadAjaxManager in Chrome, the events sent to any mouse events I'm using are passed as null. For instance, the following: <img id="Image1" src="image.gif" onclick="alert(event)" /> <rad:RadAjaxManager ID="RadAjaxManager1" runat="server"> <AjaxSettings> </AjaxSettings> </rad:RadAjaxManager> Alerts null when clicking the image. This does not happen in IE or FF. The version of the RadAjaxManager is 1.8.5.0. I'm guessing the problem does not occur in later versions, but an upgrade is not an option at the moment. I tried Telerik's support forum, but they didn't really provide any answer. What could cause such a problem? And how can it be dealt with?
