  • MINA: Performing synchronous write requests / read responses

    - by Matt Huggins
    I'm attempting to perform a synchronous write/read in a demux-based client application with MINA 2.0 RC1, but it seems to get stuck. Here is my code: public boolean login(final String username, final String password) { // block inbound messages session.getConfig().setUseReadOperation(true); // send the login request final LoginRequest loginRequest = new LoginRequest(username, password); final WriteFuture writeFuture = session.write(loginRequest); writeFuture.awaitUninterruptibly(); if (writeFuture.getException() != null) { session.getConfig().setUseReadOperation(true); return false; } // retrieve the login response final ReadFuture readFuture = session.read(); readFuture.awaitUninterruptibly(); if (readFuture.getException() != null) { session.getConfig().setUseReadOperation(true); return false; } // stop blocking inbound messages session.getConfig().setUseReadOperation(false); // determine if the login info provided was valid final LoginResponse loginResponse = (LoginResponse)readFuture.getMessage(); return loginResponse.getSuccess(); } I can see on the server side that the LoginRequest object is retrieved, and a LoginResponse message is sent. On the client side, the DemuxingProtocolCodecFactory receives the response, but after throwing in some logging, I can see that the client gets stuck on the call to readFuture.awaitUninterruptibly(). I can't for the life of me figure out why it is stuck here based upon my own code. I properly set the read operation to true on the session config, meaning that messages should be blocked. However, it seems as if the message no longer exists by time I try to read response messages synchronously. Any clues as to why this won't work for me?

  • FancyBox Callback Keydown

    - by headShrinker
    I have been working on this code, and I can't seem to figure it out. Fancybox's callbacks don't seem to work at all. I have the keyboard bound to the pagination for this gallery. But I want to unbind the keyboard from the table when fancybox opens. When fancybox opens nothing changes.... What to do?? $(document).ready(function() { $('a.active').click(function() { var url = $(this).attr('href'); $('#ajaxTable').load(url+'/1'); return false; }); $("a.fancy").fancybox({ callbackOnStart: function() { $('a#gleft a#gright').unbind("keydown"); }, 'frameWidth': 570, 'frameHeight': 470 }) $(document).keydown(function(event) { if(event.keyCode == 37 ) { var url = $('a#gleft').attr('href'); if (url != null) { $('#ajaxTable').load(url+'/1'); $(document).unbind("keydown"); } } else if(event.keyCode == 39 ) { var url = $('a#gright').attr('href'); if (url != null) { $('#ajaxTable').load(url+'/1'); $(document).unbind("keydown"); } } }); });

  • Get "term is undefined” error when trying to assign arrayList to List component dataSource

    - by user1814467
    I'm creating an online game where people log in and then have the list of current players displayed. When the user enters a "room" it dispatches an SFSEvent which includes a Room object with the list of users as User objects in that room. As that event's callback function, I get the list of current users which is an Array, switch the View Stack child index, and then I wrap the user list array in an ArrayList before I assign it to the MXML Spark List component's dataSource. Here's my code: My Actionscript Code Section (PreGame.as): private function onRoomJoin(event:SFSEvent):void { const room:Room = this._sfs.getRoomByName(PREGAME_ROOM); this.selectedChild = waitingRoom; /** I know I should be using event listeners * but this is a temporary fix, otherwise * I keep getting null object errors * do to the li_users list not being * created in time for the dataProvider assignment **/ setTimeout(function ():void { const userList:ArrayList = new ArrayList(room.userList); this.li_users.dataProvider = userList; // This is where the error gets thrown },1000); } My MXML Code: <?xml version="1.0" encoding="utf-8"?> <mx:ViewStack xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" initialize="preGame_initializeHandler(event)" > <fx:Script source="PreGame.as"/> <s:NavigatorContent id="nc_loginScreen"> /** Login Screen Code **/ </s:NavigatorContent> /** Start of Waiting Room code **/ <s:NavigatorContent id="waitingRoom"> <s:Panel id="pn_users" width="400" height="400" title="Users"> /** This is the List in question **/ <s:List id="li_users" width="100%" height="100%"/> </s:Panel> </s:NavigatorContent> </mx:ViewStack> However, I keep getting this error: TypeError: Error #1010: A term is undefined and has no properties Any ideas what I'm doing wrong? The arrayList has data, so I know it's not empty/null.

  • Locking down RAD Studio internal browser security.

    - by HMcG
    I use Firefox as my web browser, mostly for access to add-ins such as Flashblock and No-script. I noticed yesterday that the RAD Studio internal browser used for the Welcome Page etc has scripting and Active X etc enabled. Is there a way to disable scripting, or better still, block all access to non-local sources in the built-in browser?

  • Interface Casting vs. Class Casting

    - by Legatou
    I've been led to believe that casting can, in certain circumstances, become a measurable hindrance on performance. This may be moreso the case when we start dealing with incoherent webs of nasty exception throwing\catching. Given that I wish to create more correct heuristics when it comes to programming, I've been prompted to ask this question to the .NET gurus out there: Is interface casting faster than class casting? To give a code example, let's say this exists: public interface IEntity { IParent DaddyMommy { get; } } public interface IParent : IEntity { } public class Parent : Entity, IParent { } public class Entity : IEntity { public IParent DaddyMommy { get; protected set; } public IParent AdamEve_Interfaces { get { IEntity e = this; while (this.DaddyMommy != null) e = e.DaddyMommy as IEntity; return e as IParent; } } public Parent AdamEve_Classes { get { Entity e = this; while (this.DaddyMommy != null) e = e.DaddyMommy as Entity; return e as Parent; } } } So, is AdamEve_Interfaces faster than AdamEve_Classes? If so, by how much? And, if you know the answer, why?

  • What is a postback?

    - by Scott Saad
    I'm making my way into web development and have seen the word postback thrown around. Coming from a non-web based background, what does a new web developer have to know about postbacks? (i.e. what are they and when do they arise?) Any more information you'd like to share to help a newbie in the web world be aware of postbacks would be most greatly appreciated.

  • Recommended Math textbooks for programmers

    - by Tony
    I learned math in a non-English environment, I recently read some books about algorithm analysis, I found some math concepts were confusing, and seemed not the same as what I've learned. What math textbooks would you recommend that covers math concepts from the scratch and suitable for self-learning ?

  • can't write to physical drive in win 7??

    - by matt
    I wrote a disk utility that allowed you to erase whole physical drives. it uses the windows file api, calling : destFile = CreateFile("\\.\PhysicalDrive1", GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING,createflags, NULL); and then just calling WriteFile, and making sure you write in multiples of sectors, i.e. 512 bytes. this worked fine in the past, on XP, and even on the Win7 RC, all you have to do is make sure you are running it as an administrator. but now I have retail Win7 professional, it doesn't work anymore! the drives still open fine for writing, but calling WriteFile on the successfully opened Drive now fails! does anyone know why this might be? could it have something to do with opening it with shared flags? this is always what I have done before, and its worked. could it be that something is now sharing the drive? blocking the writes? is there some way to properly "unmount" A drive, or atleast the partitions on it so that I would have exclusive access to it? some other tools that used to work don't any more either, but some do, like the WD Diagnostic's erase functionality. and after it has erased the drive, my tool then works on it too! leading me to belive there is some "unmount" process I need to be doing to the drive first, to free up permission to write to it. Any ideas?

  • problem getting info from a cookie with javascript

    - by Jason
    I am having an issue with my cookies and I can't figure it out. Basically I have it set up so it checks for the cookie to see if the user is logged in, and then displays either a welcome message or a login link. It works - except that instead of returning the persons name in the welcome message it just is blank where the name should be. The cookie is there, with all the appropriate info.. not sure what I am doing wrong. var itm = new Array(); itm[0] = findCookie("ui"); if (itm[0] == null) { document.write("<h2><a href='logreg.html'>Log In or Sign Up</a></h2>"); } else { var c1 = itm[0].indexOf(","); var c2 = itm[0].indexOf(",",c1); var c3 = itm[0].indexOf(",",c2); var gname = itm[0].substring(c2,c3); document.write("<h2>Welcome "+gname+"!</h2>"); } The findCookie function is.. function findCookie(val){ var cookie = null; var findVal = val + "="; var dc = document.cookie; if (dc.length > 0) { var start = dc.indexOf(findVal); if (start >= 0) { start += findVal.length; lastVal = dc.indexOf(";", start); if (lastVal == -1) { lastVal = dc.length; } cookie = (dc.substring(start, lastVal)); } else { return cookie; } } return cookie; }

  • OpenVPN Client timing out

    - by Austin
    I recently installed OpenVPN on my Ubuntu VPS. Whenenver I try to connect to it, I can establish a connection just fine. However, everything I try to connect to times out. If I try to ping something, it will resolve the IP, but will time out after resolving the IP. (So DNS Server seems to be working correctly) My server.conf has this relevant information (At least I think it's relevant. I'm not sure if you need more or not) # Which local IP address should OpenVPN # listen on?

  • Why does calling abort() on ajax request cause error in ASP.Net MVC (IE8)

    - by user169867
    I use jquery to post to an MVC controller action that returns a table of information. The user of the page triggers this by clicking on various links. In the event the user decides to click a bunch of these links in quick succession I wanted to cancel any previous ajax request that may not have finished. I've found that when I do this (although its fine from the client's POV) I will get errors on the web application saying that "The parameters dictionary contains a null entry for parameter srtCol of non-nullable type 'System.Int32'" Now the ajax post deffinately passes in all the parameters, and if I don't try and cancel the ajax request it works just fine. But if I do cancel the request by calling abort() on the XMLHttpRequest object that ajax() returns before it finishes I get the error from ASP.Net MVC. Example: //Cancel any pevious request if (req) { req.abort(); req = null; } //Make new request req= $.ajax({ type: 'POST', url: "/Myapp/GetTbl", data: {srtCol: srt, view: viewID}, success: OnSuccess, error: OnError, dataType: "html" }); I've noticed this only happen is IE8. In FF it seems to not cuase a problem. Does anyone know how to cancel an ajax request in IE8 without causing errors for MVC? Thanks for any help.

  • Using ServletOutputStream to write very large files in a Java servlet without memory issues

    - by Martin
    I am using IBM Websphere Application Server v6 and Java 1.4 and am trying to write large CSV files to the ServletOutputStream for a user to download. Files are ranging from a 50-750MB at the moment. The smaller files aren't causing too much of a problem but with the larger files it appears that it is being written into the heap which is then causing an OutOfMemory error and bringing down the entire server. These files can only be served out to authenticated users over https which is why I am serving them through a Servlet instead of just sticking them in Apache. The code I am using is (some fluff removed around this): resp.setHeader("Content-length", "" + fileLength); resp.setContentType("application/vnd.ms-excel"); resp.setHeader("Content-Disposition","attachment; filename=\"export.csv\""); FileInputStream inputStream = null; try { inputStream = new FileInputStream(path); byte[] buffer = new byte[1024]; int bytesRead = 0; do { bytesRead = inputStream.read(buffer, offset, buffer.length); resp.getOutputStream().write(buffer, 0, bytesRead); } while (bytesRead == buffer.length); resp.getOutputStream().flush(); } finally { if(inputStream != null) inputStream.close(); } The FileInputStream doesn't seem to be causing a problem as if I write to another file or just remove the write completly the memory usage doesn't appear to be a problem. What I am thinking is that the resp.getOutputStream().write is being stored in memory until the data can be sent through to the client. So the entire file might be read and stored in the resp.getOutputStream() causing my memory issues and crashing! I have tried Buffering these streams and also tried using Channels from java.nio, none of which seems to make any bit of difference to my memory issues. I have also flushed the outputstream once per iteration of the loop and after the loop, which didn't help.

  • ASP.Net User Control Template Instantiation

    - by Chris
    Hi, I created a user control that has a template container. <cc:SearchResultItem ID="SearchResultItem1" Customer='<%# ((Customer)(((RepeaterItem)Container).DataItem)) %>' runat="server"> <NameTemplate> <%# Container.Name %> </NameTemplate> </cc:SearchResultItem> This is control is placed in a repeater which lists some customers. The customer is than bound to the user control. When the name template is instantiated in the container, the customer object is not yet available, but I need to access its name because it needs to get parsed before. protected void Page_Init(object sender, EventArgs e) { if (nameTemplate != null ) { // customer is null here, it is avaiable only after Page_Init... NameContainer container = new NameContainer(customer.Id, Parse(customer.Name)); nameTemplate.InstantiateIn(container); placeHolder.Controls.Add(container); } } Question: How can I access properties set for the user control BEFORE the template container is instantiated? Thanks in advance!

What are the other such publicly exposed end points that reflect real or almost real-time services? Any offerings specifically from Microsoft? I am basically looking for writing WCF clients for both WCF and non-WCF services...RESTful ones and even otherwise.

  • Return number of matches from c# dictionary

    - by Rickard Haake
    Hello! I have a dictionary with non unique values and I want to count the matches of a string versus the values. Basically I now do dict.ContainsValue(a) to get a bool telling me if the string a exists in dict, but I want to know not only if it exists but how many times it exists (and maybee even get a list of the keys it exists bound to) Is there a way to do this using dictionary, or should I look for a different collection? /Rickard Haake

    Hello, I have this strange problem with SDL_mixer, it doesn't want to play music. It doesn't throw any error, it just skips it. Any advice? I am compiling on linux with libvorbis. audio.h #ifndef AUDIO_H #define AUDIO_H #include <string> #include <SDL/SDL_mixer.h> class Audio { private: Mix_Music *music; public: Audio(); virtual ~Audio(); public: void setMusic(std::string path); void playMusic(); }; #endif /* AUDIO_H */ audio.cpp #include "Audio.h" #include <stdexcept> Audio::Audio() { if (0 == Mix_Init(MIX_INIT_OGG)) throw std::runtime_error(Mix_GetError()); if (-1 == Mix_OpenAudio(44100, MIX_DEFAULT_FORMAT, MIX_DEFAULT_CHANNELS, 4096)) throw std::runtime_error(Mix_GetError()); } Audio::~Audio() { Mix_FreeMusic(music); Mix_Quit(); } void Audio::setMusic(std::string path) { music = Mix_LoadMUS(path.c_str()); if (NULL == music) throw std::runtime_error(Mix_GetError()); } void Audio::playMusic() { if (NULL != music) { if (-1 == Mix_PlayMusic(music, -1)) throw std::runtime_error(Mix_GetError()); } }

  • NSTableView binding problem

    - by Niklas Ottosson
    I have only just started with XCode (v3.2.2) and Interface Builder and have run into a problem. Here is what I have done: I have made a class to be the datasource of a NSTableView: @interface TimeObjectsDS : NSControl { IBOutlet NSTableView * idTableView; NSMutableArray * timeObjects; } @property (assign) NSMutableArray * timeObjects; @property (assign) NSTableView * idTableView; - (id) init; - (void) dealloc; - (void) addTimeObject: (TimeObj *)timeObject; - (int) count; // NSTableViewDataSource Protocol functions - (int)numberOfRowsInTableView:(NSTableView *)tableView; - (id)tableView:(NSTableView *)tableView objectValueForTableColumn:(NSTableColumn *)tableColumn row: (int)row; I have then bound my NSTableView in the View to this datasource like so: I have also bound the View NSTableView to the Model idTableView variable in Interface Builder seen above In the init function I add a element to the mutable array. This is displayed correctly in the NSTableView when I run the application. However when I add another element to the array (of same type as in init) and try to call [idTableView reloadData] on the View nothing happens. In fact the Model idTableView is null. When printing the variable with NSLog(@"idTableView: %@", idTableView) I get "idTableView: (null)" Im runing out of ideas how to fix this. Any ideas to what I could do to fix the binding?
