  • Reading/writing from named pipes under mono/Linux

    - by weismat
    I would like to read/write from a named pipe/FIFo queue under Linux. I have tried the standard classes StreamWriter and other classes from System.IO, but it fails because it is using seek. Has anyone ever written/read from a named pipe using Mono?. I am managing to read and write - but not the same time...

  • Problem with waveOutWrite and waveOutGetPosition deadlock

    - by MusiGenesis
    I'm working on an app that plays audio continuously using the waveOut... API from winmm.dll. The app uses "leapfrog" buffers, which are basically a bunch of arrays of samples that you dump into the audio queue. Windows plays them seamlessly in sequence, and as each buffer completes Windows calls a callback function. Inside this function, I load the next set of samples into the buffer, process them however, and then dump the buffer back into the audio queue. In this way, the audio plays indefinitely. For animation purposes, I'm trying to incorporate waveOutGetPosition into the application (since the "buffer done" callbacks are irregular enough to cause jerky animation). waveOutGetPosition returns the current position of playback, so it's hyper-precise. The problem is that in my application, making calls to waveOutGetPosition eventually causes the application to lock up - the sound stops and the call never returns. I've boiled things down to a simple app that demonstrates the problem. You can run the app here: http://www.musigenesis.com/SO/waveOut%20demo.exe If you just hear a tiny bit of piano over and over, it's working. It's just meant to demonstrate the problem. The source code for this project is here: http://www.musigenesis.com/SO/WaveOutDemo.zip The first button runs the app in leapfrog mode without making the calls to waveOutGetPosition. If you click this, the app will play forever without breaking (the X button will close it and shut it off). The second button starts the leapfrogger and also starts a forms timer that calls the waveOutGetPosition and displays the current position. Click this and the app will run for a short while and then lock up. On my laptop, it usually locks up in 15-30 seconds; at most it's taken a minute. I have no idea how to fix this, so any help or suggestions would be most welcome. I've found very few posts on this issue, but it seems that there is a potential deadlock, either from multiple calls to waveOutGetPosition or from calls to that and waveOutWrite that occur at the same time. It's possible that I'm calling this too frequently for the system to handle.

  • How to stop UITableView moveRowAtIndexPath from leaving blank rows upon reordering

    - by coneybeare
    I am having an issue where in reordering my UITableViewCells, the tableView is not scrolling with the cell. Only a blank row appears and any subsequent scrolling gets an Array out of bounds error without any of my code in the Stack Trace. Here is a quick video of the problem. Here is the relevant code: - (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath { return indexPath.section == 1; } - (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath { BOOL ret = indexPath.section == 1 && indexPath.row < self.count; DebugLog(@"canMoveRowAtIndexPath: %d:%d %@", indexPath.section, indexPath.row, (ret ? @"YES" : @"NO")); return ret; } - (void)delayedUpdateCellBackgroundPositionsForTableView:(UITableView *)tableView { [self performSelectorOnMainThread:@selector(updateCellBackgroundPositionsForTableView:) withObject:tableView waitUntilDone:NO]; } - (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath { if (fromIndexPath.row == toIndexPath.row) return; DebugLog(@"Moved audio from %d:%d to %d:%d", fromIndexPath.section, fromIndexPath.row, toIndexPath.section, toIndexPath.row); NSMutableArray *audio = [self.items objectAtIndex:fromIndexPath.section]; [audio exchangeObjectAtIndex:fromIndexPath.row withObjectAtIndex:toIndexPath.row]; [self performSelector:@selector(delayedUpdateCellBackgroundPositionsForTableView:) withObject:tableView afterDelay:kDefaultAnimationDuration/3]; } And here is the generated Stack Trace of the crash: Exception Type: EXC_BREAKPOINT (SIGTRAP) Exception Codes: 0x0000000000000002, 0x0000000000000000 Crashed Thread: 0 Dispatch queue: com.apple.main-thread Application Specific Information: iPhone Simulator 3.2 (193.3), iPhone OS 3.0 (7A341) *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray removeObjectsInRange:]: index (6) beyond bounds (6)' Thread 0 Crashed: Dispatch queue: com.apple.main-thread 0 CoreFoundation 0x302ac924 ___TERMINATING_DUE_TO_UNCAUGHT_EXCEPTION___ + 4 1 libobjc.A.dylib 0x93cb2509 objc_exception_throw + 56 2 CoreFoundation 0x3028e5fb +[NSException raise:format:arguments:] + 155 3 CoreFoundation 0x3028e55a +[NSException raise:format:] + 58 4 Foundation 0x305684e9 _NSArrayRaiseBoundException + 121 5 Foundation 0x30553a6e -[NSCFArray removeObjectsInRange:] + 142 6 UIKit 0x30950105 -[UITableView(_UITableViewPrivate) _updateVisibleCellsNow] + 862 7 UIKit 0x30947715 -[UITableView layoutSubviews] + 250 8 QuartzCore 0x0090bd94 -[CALayer layoutSublayers] + 78 9 QuartzCore 0x0090bb55 CALayerLayoutIfNeeded + 229 10 QuartzCore 0x0090b3ae CA::Context::commit_transaction(CA::Transaction*) + 302 11 QuartzCore 0x0090b022 CA::Transaction::commit() + 292 12 QuartzCore 0x009132e0 CA::Transaction::observer_callback(__CFRunLoopObserver*, unsigned long, void*) + 84 13 CoreFoundation 0x30245c32 __CFRunLoopDoObservers + 594 14 CoreFoundation 0x3024503f CFRunLoopRunSpecific + 2575 15 CoreFoundation 0x30244628 CFRunLoopRunInMode + 88 16 GraphicsServices 0x32044c31 GSEventRunModal + 217 17 GraphicsServices 0x32044cf6 GSEventRun + 115 18 UIKit 0x309021ee UIApplicationMain + 1157 19 XXXXXXXX 0x0000278a main + 104 (main.m:12) 20 XXXXXXXX 0x000026f6 start + 54 NOte that the array out of bounds length is not the length of my elements (I have 9), but always something smaller. I have been trying to solve this for many hours days without avail… any ideas? UPDATE: More code as requested In my delegate: - (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath { return UITableViewCellEditingStyleNone; } - (NSIndexPath *)tableView:(UITableView *)tableView targetIndexPathForMoveFromRowAtIndexPath:(NSIndexPath *)sourceIndexPath toProposedIndexPath:(NSIndexPath *)proposedDestinationIndexPath { int count = [(UAPlaylistEditDataSource *)self.dataSource count]; if (proposedDestinationIndexPath.section == 0) { return [NSIndexPath indexPathForRow:0 inSection:sourceIndexPath.section]; }else if (proposedDestinationIndexPath.row >= count) { return [NSIndexPath indexPathForRow:count-1 inSection:sourceIndexPath.section]; } return proposedDestinationIndexPath; } …thats about it. I am using the three20 framework and I have not had any issues with reordering till now. The problem is also not in the updateCellBackgroundPositionsForTableView: method as it still crashes when this is commented out.

  • Using NServiceBus with multiple application both act as Publisher and Subscriber

    - by Yoann. B
    Hi, I'm trying to use NServiceBus to make 4 applications communicating together. All these applications have to act as Publisher and Subscriber. The only way i founded ti get it workiing is to create a "master" queue named Server, on which MessageEndpointMappings in all applications configuration is mapped to, but i think it's not the good way ... So how should i configure NServiceBus on all these application to get this working ? Thanks.

  • request response with activemq - always send double response.

    - by Chris Valley
    Hi, I'm new at activeMq. I tried to create a simple request response like this. public Listener(string destination) { // set factory ConnectionFactory factory = new ConnectionFactory(URL); IConnection connection; try { connection = factory.CreateConnection(); connection.Start(); ISession session = connection.CreateSession(); // create consumer for designated destination IMessageConsumer consumer = session.CreateConsumer(new Apache.NMS.ActiveMQ.Commands.ActiveMQQueue(destination)); consumer.Listener += new MessageListener(consumer_Listener); Console.ReadLine(); } catch (Exception ex) { Console.WriteLine(ex.ToString()); throw new Exception("Exception in Listening ", ex); } } The OnMessage static void consumer_Listener(IMessage message) { IConnectionFactory factory = new ConnectionFactory("tcp://localhost:61616/"); using (IConnection connection = factory.CreateConnection()) { //Create the Session using (ISession session = connection.CreateSession()) { //Create the Producer for the topic/queue // IMessageProducer prod = session.CreateProducer(new Apache.NMS.ActiveMQ.Commands.ActiveMQTempQueue(message.NMSDestination)); IMessageProducer producer = session.CreateProducer(message.NMSDestination); // Create Response // IMessage response = session.CreateMessage(); ITextMessage response = producer.CreateTextMessage("Replied from VS2010 Test"); //response.NMSReplyTo = new Apache.NMS.ActiveMQ.Commands.ActiveMQQueue("testQ1"); response.NMSCorrelationID = message.NMSCorrelationID; if (message.NMSReplyTo != null) { producer.Send(message.NMSReplyTo, response); Console.WriteLine("Receive: " + ((ITextMessage)message).NMSCorrelationID); Console.WriteLine("Received from : " + message.NMSDestination.ToString()); Console.WriteLine("----------------------------------------------------"); } } } } Every time i tried to send a request to the listener, the response always send repeatedly. The first response will have NMSReplyTo properties while the other not. My workaround to stop this situation by cheking the NMSReplyTo properties if (message.NMSReplyTo != null) { producer.Send(message.NMSReplyTo, response); Console.WriteLine("Receive: " + ((ITextMessage)message).NMSCorrelationID); Console.WriteLine("Received from : " + message.NMSDestination.ToString()); Console.WriteLine("----------------------------------------------------"); } In my understanding, this happened because there was a circular send response in the listener to the same Queue. Could you guys help me how to fix this? Many Thanks, Chris

  • Ruby1.9 and Amazon SQS?

    - by fields
    Is there a good library/gem for accessing Amazon SQS from ruby1.9? The Amazon ruby example and right_aws do not work as-is with ruby1.9. I'd strongly prefer something that's known to work under reasonably heavy load (a few hundred thousand queue items or more per day).

  • Webview crash with Garbage Collector ON

    - by user273666
    Hi, I have a very specific web page that causes webview to crash with the Garnage Collector ON (does not crash when OFF). Easy to reproduce: create a document base application, drop a webview, and have the following line (button perhaps). - (void)connectSearch:(id)sender { [[webView mainFrame] loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://apple.com"]]]; } I guess this scenario is only valid while Apple advertises their new iPad. At the bottom of the page there is two video you can watch. Click on the one on the right. When it is playing, click on the Close button (link) top left - which sends #SwapViewPreviousSelection - and that's it, it crashes. I'm just learning about the garbage collector but I suspect something is collected that should not. Any idea what can prevent the crash, other than turning off the garbage collector? Thank you.

  • Invert a stack, without using extra data structures?

    - by vks
    How would you invert a stack, without using extra data structures, like a second, or temporary, stack. Thus no stack1-stack2 or stack-queue-stack implementation in the answer. You just have access to push/pop feature of a standard stack. I think there is way to do it by keeping a global counter and using pointer manipulation. If I solve it myself, I will post it. If someone else figures it out, please post your solution.

  • Simple thread-safe non-blocking file logger class in c#

    - by Jason Renlan
    I have a web application, that will log some information to a file. I am looking for a simple thread-safe non-blocking file logger class in c#. I have little experience with threading. I known there are great logging components out there like log4Net, Enterprise Library Logging Block, ELMAH, but I do not want an external dependence for my application. I was thinking about using this queue implementation http://www.codeproject.com/KB/cpp/lockfreeq.aspx

  • Using com.sun.net.httpserver.HttpServer for comet/cometd

    - by Paul
    Hi Wayne :) I want to use HttpServer, which you mentioned, and I think is cool to do comet/cometd. I am wondering how tough it is to do it so that I can take the waiting connections off the thread and into some waiting queue. Also, am I correct in that it looks like it is using nio? Also, is there any better examples? I always get caught up in the terminology that the javadoc uses... Thanks :)

  • Problems related to showing MessageBox from non-GUI threads

    - by Hans Løken
    I'm working on a heavily data-bound Win.Forms application where I've found some strange behavior. The app has separate I/O threads receiving updates through asynchronous web-requests which it then sends to the main/GUI thread for processing and updating of application-wide data-stores (which in turn may be data-bound to various GUI-elements, etc.). The server at the other end of the web-requests requires periodic requests or the session times out. I've gone through several attempted solutions of dealing with thread-issues etc. and I've observed the following behavior: If I use Control.Invoke for sending updates from I/O-thread(s) to main-thread and this update causes a MessageBox to be shown the main form's message pump stops until the user clicks the ok-button. This also blocks the I/O-thread from continuing eventually leading to timeouts on the server. If I use Control.BeginInvoke for sending updates from I/O-thread(s) to main-thread the main form's message pump does not stop, but if the processing of an update leads to a messagebox being shown, the processing of the rest of that update is halted until the user clicks ok. Since the I/O-threads keep running and the message pump keeps processing messages several BeginInvoke's for updates may be called before the one with the message box is finished. This leads to out-of-sequence updates which is unacceptable. I/O-threads add updates to a blocking queue (very similar to http://stackoverflow.com/questions/530211/creating-a-blocking-queuet-in-net/530228#530228). GUI-thread uses a Forms.Timer that periodically applies all updates in the blocking queue. This solution solves both the problem of blocking I/O threads and sequentiality of updates i.e. next update will be never be started until previous is finished. However, there is a small performance cost as well as introducing a latency in showing updates that is unacceptable in the long run. I would like update-processing in the main-thread to be event-driven rather than polling. So to my question. How should I do this to: avoid blocking the I/O-threads guarantee that updates are finished in-sequence keep the main message pump running while showing a message box as a result of an update.

  • Wait for function to finish before starting again.

    - by Matthew Brown
    Good Morning, I am trying to call the same function everytime the user presses a button. Here is what happens at the moment.. User clicks button - Calls function - function takes 1000ms+ to finish (due to animation with jQuery and AJAX calls) What I want to happen is every time the user presses the button it adds the function to the queue, waits for the previous call to finish, and then starts.. Is this possible? Sorry if my explanation is a bit confusing.. Thanks Matthew

  • How to produce precisely-timed tone and silence in C#

    - by Bob Denny
    I have a C# project that plays Morse code for RSS feeds. I write it using Managed DirectX, only to discover that Managed DirectX is old and deprecated. The task I have is to play pure sine wave bursts interspersed with silence periods (the code) which are precisely timed as to their duration. I need to be able to call a function which plays a pure tone for so many milliseconds, then Thread.Sleep() then play another, etc. At its fastest, the tones and spaces can be as short as 40ms. It's working quite well in Managed DirectX. To get the precisely timed tone I create 1 sec. of sine wave into a secondary buffer, then to play a tone of a certain duration I seek forward to within x milliseconds of the end of the buffer then play. I've tried System.Media.SoundPlayer. It's a loser because you have to Play(), Sleep(), then Stop() for arbitrary tone lengths. The result is a tone that is too long, variable by CPU load. It takes an indeterminate amount of time to actually stop the tone. I then embarked on a lengthy attempt to use NAudio 1.3. I ended up with a memory resident stream providing the tone data, and again seeking forward leaving the desired length of tone remaining in the stream, then playing. This worked OK on the DirectSoundOut class for a while (see below) but the WaveOut class quickly dies with an internal assert saying that buffers are still on the queue despite PlayerStopped = true. This is odd since I play to the end then put a wait of the same duration between the end of the tone and the start of the next. You'd think that 80ms after starting Play of a 40 ms tone that it wouldn't have buffers on the queue. DirectSoundOut works well for a while, but its problem is that for every tone burst Play() it spins off a separate thread. Eventually (5 min or so) it just stops working. You can see thread after thread after thread exiting in the Output window while running the project in VS2008 IDE. I don't create new objects during playing, I just Seek() the tone stream then call Play() over and over, so I don't think it's a problem with orphaned buffers/whatever piling up till it's choked. I'm out of patience on this one, so I'm asking in the hopes that someone here has faced a similar requirement and can steer me in a direction with a likely solution. Thanks in advance...

  • PyQt threads and signals - how to properly retrieve values

    - by Cawas
    Using Python 2.5 and PyQt, I couldn't find any question this specific in Python, so sorry if I'm repeating the other Qt referenced questions below, but I couldn't easily understand that C code. I've got two classes, a GUI and a thread, and I'm trying to get return values from the thread. I've used the link in here as base to write my code, which is working just fine. To sum it up and illustrate the question in code here (I don't think this code will run on itself): class MainWindow (QtGui.QWidget): # this is just a reference and not really relevant to the question def __init__ (self, parent = None): QtGui.QWidget.__init__(self, parent) self.thread = Worker() # this does not begin a thread - look at "Worker.run" for mor details self.connect(self.thread, QtCore.SIGNAL('finished()'), self.unfreezeUi) self.connect(self.thread, QtCore.SIGNAL('terminated()'), self.unfreezeUi) self.connect(self.buttonDaemon, QtCore.SIGNAL('clicked()'), self.pressDaemon) # the problem begins below: I'm not using signals, or queue, or whatever, while I believe I should def pressDaemon (self): self.buttonDaemon.setEnabled(False) if self.thread.isDaemonRunning(): self.thread.setDaemonStopSignal(True) self.buttonDaemon.setText('Daemon - converts every %s sec'% args['daemonInterval']) else: self.buttonConvert.setEnabled(False) self.thread.startDaemon() self.buttonDaemon.setText('Stop Daemon') self.buttonDaemon.setEnabled(True) # this whole class is just another reference class Worker (QtCore.QThread): daemonIsRunning = False daemonStopSignal = False daemonCurrentDelay = 0 def isDaemonRunning (self): return self.daemonIsRunning def setDaemonStopSignal (self, bool): self.daemonStopSignal = bool def __init__ (self, parent = None): QtCore.QThread.__init__(self, parent) self.exiting = False self.thread_to_run = None # which def will be running def __del__ (self): self.exiting = True self.thread_to_run = None self.wait() def run (self): if self.thread_to_run != None: self.thread_to_run(mode='continue') def startDaemon (self, mode = 'run'): if mode == 'run': self.thread_to_run = self.startDaemon # I'd love to be able to just pass this as an argument on start() below return self.start() # this will begin the thread # this is where the thread actually begins self.daemonIsRunning = True self.daemonStopSignal = False sleepStep = 0.1 # don't know how to interrupt while sleeping - so the less sleepStep, the faster StopSignal will work # begins the daemon in an "infinite" loop while self.daemonStopSignal == False and not self.exiting: # here, do any kind of daemon service delay = 0 while self.daemonStopSignal == False and not self.exiting and delay < args['daemonInterval']: time.sleep(sleepStep) # delay is actually set by while, but this holds for N second delay += sleepStep # daemon stopped, reseting everything self.daemonIsRunning = False self.emit(QtCore.SIGNAL('terminated')) Tho it's quite big, I hope this is pretty clear. The main point is on def pressDaemon. Specifically all 3 self.thread calls. The last one, self.thread.startDaemon() is just fine, and exactly as the example. I doubt that represents any issue. The problem is being able to set the Daemon Stop Signal and retrieve the value if it's running. I'm not sure that it's possible to set a stop signal on QtCore.QtThread, because I've tried doing the same way and it didn't work. But I'm pretty sure it's not possible to retrieve a return result from the emit. So, there it is. I'm using direct calls to the thread class, and I'm almost positive that's not a good design and will probably fail when running under stress. I read about that queue, but I'm not sure it's the proper solution here, or if I should be using Qt at all, since this is Python. And just maybe there's nothing wrong with the way I'm doing.

  • Incorrect XML produced by SUDS

    - by Ben
    Hi, I am trying to talk to a SOAP web service using SUDS and Python. After lots of messing around learning Python (yes I am new to this) and working out how to use SUDS I have come across a problem. The signature of the web method I am calling, according to suds, is (FWTCaseCreate){ ClassificationEventCode = None Priority = None Title = None Description = None Queue = None DueDate = None AssociatedObject = (FWTObjectBriefDetails){ ObjectID = (FWTObjectID){ ObjectType = None ObjectReference[] = <empty> } ObjectDescription = None Details = None Category = None } Form = (FWTCaseForm){ FormField[] = <empty> FormName = None FormKey = None } Internal = None InteractionID = None XCoord = None YCoord = None } So I use SUDS to create the classes that I want and send it to the method. However I get an error. So I turned logging on and I can see that the XML that is being sent is not correct which is causing a deserialize error. The SOAP package looks like the following <?xml version="1.0" encoding="UTF-8"?> <SOAP-ENV:Envelope xmlns:ns0="http://www.lagan.com/wsdl/FLTypes" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"> <SOAP-ENV:Header> <wsse:Security> <wsse:BinarySecurityToken>eaadf1ddff99a8</wsse:BinarySecurityToken> </wsse:Security> </SOAP-ENV:Header> <ns1:Body> <ns0:FWTCaseCreate> <ClassificationEventCode> <ClassificationEventCode>2000023</ClassificationEventCode> <Priority>1</Priority> <Title>testing</Title> <Description>testing</Description> <Queue/> <Internal>True</Internal> <XCoord>356570</XCoord> <YCoord>168708</YCoord> </ClassificationEventCode> </ns0:FWTCaseCreate> </ns1:Body> As you can see there is a 'ClassificationEventCode' element around all the other elements, this should not be there. If I cut and paste this xml into SOAPUI and first remove this element and then post it directly to the web service it works successfully. Does anyone have any ideas why this is happening? I guess SUDS thinks that it should be there based on the WSDL. Thanks.

  • GCD and AppleEvents / NSOperationQueue and AppleScript

    - by mahal tertin
    As i understood, the threads provided by GCD do have a runloop but no source/port. Now i use some of methods that call AppleScripts thru AppleEvents inside an NSOperationQueue. And sometimes my app crashes with following stacktrace. my questions: Usage of AppleScript inside a NSInvocationOperation or NSBlockOperation Usage of AppleEvents inside GCD-Threads do i have to add a source / port to a runloop of a gcd-thread before using AppleEvents? do i have to add a source / port to a runloop of a gcd-thread before using [CATransaction commit]? do i have to add a source / port to a runloop of a gcd-thread before using [NSObject performSelectorAfterDelay...] ? if yes, how? can i simply call CFRunLoopRunInMode(kCFRunLoopDefaultMode, 5.0, false); /// or 30 or the defined timeout of appleevent? ..

  • Which third party website thumbnailing services do you use?

    - by Ben Delarre
    I've got a requirement for showing thumbnails of arbitrary websites. I need to be able to show small thumbnails (120px by 90px), and larger thumbnails of around 480px wide. I'll need to specify the queue and invalid placeholder images and preferably have a pingback when the queued images are processed so I can respond appropriately. I'd also need a simple API I can use either directly embedded in my HTML, or from a simple web request to queue the images. I've been looking at various services ranging from low-fi services, to large scale ones - here's some examples: www.bitpixels.com Uses Google AppEngine, seems like a prototype or a toy. Free! www.websnapr.com Tried using this, made a free account and requested a thumbnail. Waited a few minutes and refreshed a couple of times, and ended up having the account banned. Free is tricky yes, but if I can't try it out successfully I'm disinclined to pay. www.shrinktheweb.com Free account seems to be very quick. Lots of documentation on the site, and even covers local caching of the images to your own server (documentation mostly in PHP). Quality of thumbnails look good, and there appear to be sufficient options for setting thumbnail placeholder images and parameters for altering how the thumbnailing is done. Also supports large 'screenshots' of URLs - very useful for me. Discovered the PRO pricing is an à la carte menu, allowing me to select just the features I want and keep the monthly cost low. Excellent stuff, have decided to use this service. www.thumbalizr.com Good coverage of thumbnail sizes and control options - even allowing specification for browser width when thumbnailing. No ping-back, but I can live without that. Supports local caching of images with PHP API, would prefer .NET, but can port it if necessary. Looks like a fairly professional service but seems fairly expensive for the number of thumbnails you get to generate. apologies for lack of proper linking - spam protection! I'm not entirely convinced by any of them, and since this will be a long term service I'd like some stability and support. I'm willing to pay for the service, but I'd want something that fulfills most if not all of my requirements for that. I should also mention that we're hosted on Windows under IIS, so local solutions involving Xvfb and the like sadly can't be used for this project. So my question is: what services do you use? How have they panned out, are you happy with them?

  • How can I fix the website's splash page to work in IE8 and below?

    - by Abriel
    I have been trying to figure out for the longest time how I can get the splash page on this website to work correctly in IE8 and below? Right now, it works on all the other browsers (Firefox, Chrome, Safari). Here is the website: http://gds.parkland.edu/student/fall10/gds220/ashipley/p2/final_revised/index.html jQuery code: /* Sliding Affect Splash Page */ $(function() { $('.box').each(function() { var $this = $(this); $.data(this, 'css', { width: $this.css('width'), background: $this.css('background-image') }); }); }); function restore() { $('.box').each(function() { var orig = $.data(this, 'css'); $(this).animate({ width: orig.width },{queue:false}); $(this).css({backgroundImage: orig.background}); }); } /* box 1 */ function boxHover(){ $('.box').stop().animate({'width' : '596px'},{queue:false}); } function box1master(){ $('.box2').css({backgroundImage: 'url(images/splash/zatgun_midtop.jpg)'}); $('.box3').css({backgroundImage: 'url(images/splash/zatgun_midbottom.jpg)'}); $('.box4').css({backgroundImage: 'url(images/splash/zatgun_bottom.jpg)'}); } function box2master(){ $('.box1').css({backgroundImage: 'url(images/splash/bryan_top.jpg)'}); $('.box3').css({backgroundImage: 'url(images/splash/bryan_midbottom.jpg)'}); $('.box4').css({backgroundImage: 'url(images/splash/bryan_bottom.jpg)'}); } function box3master(){ $('.box1').css({backgroundImage:'url(images/splash/galleries_top.jpg)'}); $('.box2').css({backgroundImage: 'url(images/splash/galleries_midtop.jpg)'}); $('.box4').css({backgroundImage: 'url(images/splash/galleries_bottom.jpg)'}); } function box4master(){ $('.box1').css({backgroundImage: 'url(images/splash/contact_top.jpg)'}); $('.box2').css({backgroundImage: 'url(images/splash/contact_midtop.jpg)'}); $('.box3').css({backgroundImage: 'url(images/splash/contact_midbottom.jpg)'}); } $(document).ready(function(){ $('.box1').hover(function(){ boxHover(); box1master(); }, function(){ restore(); }); $('.box2').hover(function(){ boxHover(); box2master(); }, function(){ restore(); }); $('.box3').hover(function(){ boxHover(); box3master(); }, function(){ restore(); }); $('.box4').hover(function(){ boxHover(); box4master(); }, function(){ restore(); }); }); I wonder if I could change the spacing in-between each of the boxes using jQuery or if I somehow have to do this in the CSS/HTML?
