  • ASP.net FFMPEG video conversion receiving error: "Error number -2 occurred"

    - by Pete
    Hello, I am attempting to integrate FFMPEG into my asp.net website. The process I am trying to complete is to upload a video, check if it is .avi, .mov, or .wmv and then convert this video into an mp4 using x264 so my flash player can play it. I am using an http handler (ashx) file to handle my upload. This is where I am also putting my conversion code. I am not sure if this is the best place to put it, but I wanted to see if i could at least get it working. Additionally, I was able to complete the conversion manually through cmd line. The error -2 comes up when i output the standard error from the process I executed. This is the error i receive: FFmpeg version SVN-r23001, Copyright (c) 2000-2010 the FFmpeg developers built on May 1 2010 06:06:15 with gcc 4.4.2 configuration: --enable-memalign-hack --cross-prefix=i686-mingw32- --cc=ccache-i686-mingw32-gcc --arch=i686 --target-os=mingw32 --enable-runtime-cpudetect --enable-avisynth --enable-gpl --enable-version3 --enable-bzlib --enable-libgsm --enable-libfaad --enable-pthreads --enable-libvorbis --enable-libtheora --enable-libspeex --enable-libmp3lame --enable-libopenjpeg --enable-libxvid --enable-libschroedinger --enable-libx264 --enable-libopencore_amrwb --enable-libopencore_amrnb libavutil 50.15. 0 / 50.15. 0 libavcodec 52.66. 0 / 52.66. 0 libavformat 52.61. 0 / 52.61. 0 libavdevice 52. 2. 0 / 52. 2. 0 libswscale 0.10. 0 / 0.10. 0 532010_Robotica_720.wmv: Error number -2 occurred here is the code below: <%@ WebHandler Language="VB" Class="upload" %> Imports System Imports System.Web Imports System.IO Imports System.Diagnostics Imports System.Threading Public Class upload : Implements IHttpHandler Public currentTime As System.DateTime Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest currentTime = System.DateTime.Now If (Not context.Request.Files("Filedata") Is Nothing) Then Dim file As HttpPostedFile : file = context.Request.Files("Filedata") Dim targetDirectory As String : targetDirectory = HttpContext.Current.Server.MapPath(context.Request("folder")) Dim targetFilePath As String : targetFilePath = Path.Combine(targetDirectory, currentTime.Month & currentTime.Day & currentTime.Year & "_" & file.FileName) Dim fileNameArray As String() fileNameArray = Split(file.FileName, ".")

  • Streaming a webcam from Silverlight 4 (Beta)

    - by Ken Smith
    The new webcam stuff in Silverlight 4 is darned cool. By exposing it as a brush, it allows scenarios that are way beyond anything that Flash has. At the same time, accessing the webcam locally seems like it's only half the story. Nobody buys a webcam so they can take pictures of themselves and make funny faces out of them. They buy a webcam because they want other people to see the resulting video stream, i.e., they want to stream that video out to the Internet, a lay Skype or any of the dozens of other video chat sites/applications. And so far, I haven't figured out how to do that with It turns out that it's pretty simple to get a hold of the raw (Format32bppArgb formatted) bytestream, as demonstrated here. But unless we want to transmit that raw bytestream to a server (which would chew up way too much bandwidth), we need to encode that in some fashion. And that's more complicated. MS has implemented several codecs in Silverlight, but so far as I can tell, they're all focused on decoding a video stream, not encoding it in the first place. And that's apart from the fact that I can't figure out how to get direct access to, say, the H.264 codec in the first place. There are a ton of open-source codecs (for instance, in the ffmpeg project here), but they're all written in C, and they don't look easy to port to C#. Unless translating 10000+ lines of code that look like this is your idea of fun :-) const int b_xy= h->mb2b_xy[left_xy[i]] + 3; const int b8_xy= h->mb2b8_xy[left_xy[i]] + 1; *(uint32_t*)h->mv_cache[list][cache_idx ]= *(uint32_t*)s->current_picture.motion_val[list][b_xy + h->b_stride*left_block[0+i*2]]; *(uint32_t*)h->mv_cache[list][cache_idx+8]= *(uint32_t*)s->current_picture.motion_val[list][b_xy + h->b_stride*left_block[1+i*2]]; h->ref_cache[list][cache_idx ]= s->current_picture.ref_index[list][b8_xy + h->b8_stride*(left_block[0+i*2]>>1)]; h->ref_cache[list][cache_idx+8]= s->current_picture.ref_index[list][b8_xy + h->b8_stride*(left_block[1+i*2]>>1)]; The mooncodecs folder within the Mono project (here) has several audio codecs in C# (ADPCM and Ogg Vorbis), and one video codec (Dirac), but they all seem to implement just the decode portion of their respective formats, as do the java implementations from which they were ported. I found a C# codec for Ogg Theora (csTheora, http://www.wreckedgames.com/forum/index.php?topic=1053.0), but again, it's decode only, as is the jheora codec on which it's based. Of course, it would presumably be easier to port a codec from Java than from C or C++, but the only java video codecs that I found were decode-only (such as jheora, or jirac). So I'm kinda back at square one. It looks like our options for hooking up a webcam (or microphone) through Silverlight to the Internet are: (1) Wait for Microsoft to provide some guidance on this; (2) Spend the brain cycles porting one of the C or C++ codecs over to Silverlight-compatible C#; (3) Send the raw, uncompressed bytestream up to a server (or perhaps compressed slightly with something like zlib), and then encode it server-side; or (4) Wait for someone smarter than me to figure this out and provide a solution. Does anybody else have any better guidance? Have I missed something that's just blindingly obvious to everyone else? (For instance, does Silverlight 4 somewhere have some classes I've missed that take care of this?)

  • MXMLC Ant task results in java.lang.OutOFMemoryError

    - by Mims H. Wright
    I'm making a change to a set of code for a Flex project that I didn't write and was set up to compile using ant tasks. I assume that the codebase was stable at the last checkin but I'm running into memory issues when trying to build a project using MXMLC and ant (see stack trace below). Before, I was just getting an out of memory error. I tried using a different machine and got this more verbose exception (including problems with the image fetcher). I've tried using various versions of the SDK, I've tried replacing the <mxmlc> tag with <exec executable="mxmlc"> with no luck. Here is my java version in case that has anything to do with it: » java -version java version "1.6.0_20" Java(TM) SE Runtime Environment (build 1.6.0_20-b02-279-10M3065) Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01-279, mixed mode) Any help would be appreciated.

  • JSF: Cannot catch ViewExpiredException

    - by ifischer
    I'm developing a JSF 2.0 application on Glassfish v3 and i'm trying to handle the ViewExpiredException. But whatever i do, i always get a Glassfish error report instead of my own error page. To simulate the occurrence of the VEE, i inserted the following function into my backing bean, which fires the VEE. I'm triggering this function from my JSF page through a commandLink. The Code: @Named public class PersonHome { (...) public void throwVEE() { throw new ViewExpiredException(); } } At first i tried it by simply adding an error-page to my web.xml: <error-page> <exception-type>javax.faces.application.ViewExpiredException</exception-type> <location>/error.xhtml</location> </error-page> But this doesn't work, i'm not redirected to error but i'm shown the Glassfish errorpage, which shows a HTTP Status 500 page with the following content: description:The server encountered an internal error () that prevented it from fulfilling this request. exception: javax.servlet.ServletException: javax.faces.application.ViewExpiredException root cause: javax.faces.el.EvaluationException:javax.faces.application.ViewExpiredException root cause:javax.faces.application.ViewExpiredException Next thing i tried was to write ExceptionHandlerFactory and a CustomExceptionHandler, as described in JavaServerFaces 2.0 - The Complete Reference. So i inserted the following tag into faces-config.xml: <factory> <exception-handler-factory> exceptions.ExceptionHandlerFactory </exception-handler-factory> </factory> And added these classes: The factory: package exceptions; import javax.faces.context.ExceptionHandler; public class ExceptionHandlerFactory extends javax.faces.context.ExceptionHandlerFactory { private javax.faces.context.ExceptionHandlerFactory parent; public ExceptionHandlerFactory(javax.faces.context.ExceptionHandlerFactory parent) { this.parent = parent; } @Override public ExceptionHandler getExceptionHandler() { ExceptionHandler result = parent.getExceptionHandler(); result = new CustomExceptionHandler(result); return result; } } The custom exception handler: package exceptions; import java.util.Iterator; import javax.faces.FacesException; import javax.faces.application.NavigationHandler; import javax.faces.application.ViewExpiredException; import javax.faces.context.ExceptionHandler; import javax.faces.context.ExceptionHandlerWrapper; import javax.faces.context.FacesContext; import javax.faces.event.ExceptionQueuedEvent; import javax.faces.event.ExceptionQueuedEventContext; class CustomExceptionHandler extends ExceptionHandlerWrapper { private ExceptionHandler parent; public CustomExceptionHandler(ExceptionHandler parent) { this.parent = parent; } @Override public ExceptionHandler getWrapped() { return this.parent; } @Override public void handle() throws FacesException { for (Iterator<ExceptionQueuedEvent> i = getUnhandledExceptionQueuedEvents().iterator(); i.hasNext();) { ExceptionQueuedEvent event = i.next(); System.out.println("Iterating over ExceptionQueuedEvents. Current:" + event.toString()); ExceptionQueuedEventContext context = (ExceptionQueuedEventContext) event.getSource(); Throwable t = context.getException(); if (t instanceof ViewExpiredException) { ViewExpiredException vee = (ViewExpiredException) t; FacesContext fc = FacesContext.getCurrentInstance(); NavigationHandler nav = fc.getApplication().getNavigationHandler(); try { // Push some useful stuff to the flash scope for // use in the page fc.getExternalContext().getFlash().put("expiredViewId", vee.getViewId()); nav.handleNavigation(fc, null, "/login?faces-redirect=true"); fc.renderResponse(); } finally { i.remove(); } } } // At this point, the queue will not contain any ViewExpiredEvents. // Therefore, let the parent handle them. getWrapped().handle(); } } But STILL i'm NOT redirected to my error page - i'm getting the same HTTP 500 error like above. What am i doing wrong, what could be missing in my implementation so that the exception is handled correctly?

  • Cisco PIX 8.0.4, static address mapping not working?

    - by Bill
    upgrading a working Pix running 5.3.1 to 8.0.4. The memory/IOS upgrade went fine, but the 8.0.4 configuration is not quite working 100%. The 5.3.1 config on which it was based is working fine. Basically, I have three networks (inside, outside, dmz) with some addresses on the dmz statically mapped to outside addresses. The problem seems to be that those addresses can't send or receive traffic from the outside (Internet.) Stuff on the DMZ that does not have a static mapping seems to work fine. So, basically: Inside - outside: works Inside - DMZ: works DMZ - inside: works, where the rules allow it DMZ (non-static) - outside: works But: DMZ (static) - outside: fails Outside - DMZ: fails (So, say, udp 1194 traffic to .102, http to .104) I suspect there's something I'm missing with the nat/global section of the config, but can't for the life of me figure out what. Help, anyone? The complete configuration is below. Thanks for any thoughts! !

  • Simple animation using C#/Windows Forms

    - by clintp
    I need to knock out a quick animation in C#/Windows Forms for a Halloween display. Just some 2D shapes moving about on a solid background. Since this is just a quick one-off project I really don't want to install and learn an entire new set of tools for this. (DirectX dev kits, Silverlight, Flash, etc..) I also have to install this on multiple computers so anything beyond the basic .Net framework (2.0) would be a pain in the arse. For tools I've got VS2k8, 25 years of development experience, a wheelbarrow, holocaust cloak, and about 2 days to knock this out. I haven't done animation since using assembler on my Atari 130XE (hooray for page flipping and player/missile graphics!) Advice? Here's some of the things I'd like to know: I can draw on any empty widget (like a panel) by fiddling with it's OnPaint handler, right? That's how I'd draw a custom widget. Is there a better technique than this? Is there a page-flipping technique for this kind of thing in Windows Forms? I'm not looking for a high frame rate, just as little flicker/drawing as necessary. Thanks. Post Mortem Edit ... "a couple of coding days later" Well, the project is done. The links below came in handy although a couple of them were 404. (I wish SO would allow more than one reply to be marked "correct"). The biggest problem I had to overcome was flickering, and a persistent bug when I tried to draw on the form directly. Using the OnPaint event for the Form: bad idea. I never got that to work; lots of mysterious errors (stack overflows, or ArgumentNullExceptions). I wound up using a panel sized to fill the form and that worked fine. Using the OnPaint method is slow anyway. Somewhere online I read that building the PaintEventArgs was slow, and they weren't kidding. Lots of flickering went away when I abandoned this. Skip the OnPaint/Invalidate() and just paint it yourself. Setting all of the "double buffering" options on the form still left some flicker that had to be fixed. (And I found conflicting docs that said "set them on the control" and "set them on the form". Well controls don't have a .SetStyle() method.) I haven't tested without them, so they might be doing something (this is the form): this.SetStyle(ControlStyles.UserPaint, true); this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true); this.SetStyle(ControlStyles.AllPaintingInWmPaint, true); So the workhorse of the code wound up looking like (pf is the panel control): void PaintPlayField() { Bitmap bufl = new Bitmap(pf.Width, pf.Height); using (Graphics g = Graphics.FromImage(bufl)) { g.FillRectangle(Brushes.Black, new Rectangle(0, 0, pf.Width, pf.Height)); DrawItems(g); DrawMoreItems(g); pf.CreateGraphics().DrawImageUnscaled(bufl, 0, 0); } } And I just called PaintPlayField from the inside of my Timer loop. No flicker at all.

  • How to use GWT when downloading Files with a Servlet?

    - by molleman
    Hello Guys I am creating a simple project that will allow me to upload and download files using gwt. i am having trouble with the downloading of files that are on my server. For the file upload i used http://code.google.com/p/gwtupload/ and followed the instructions there. My file is stored on the server outside of the website container(on the hard drive), Now when it comes to the downloading of a file, i want a user to press a download button and whatever item is currently selected will download. i dont really know how this will be done i know i need a download servlet public class DownloadAttachmentServlet extends HttpServlet { @Override protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { // TODO Auto-generated method stub super.doGet(req, resp); } @Override protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException { String fileName = (String) req.getSession().getAttribute("fileName"); YFUser user = (YFUser) req.getSession().getAttribute(TestServiceImpl.SESSION_USER); if (user == null) throw new ServletException("Invalid Session"); InputStream in = null; OutputStream out = resp.getOutputStream(); FileInputStream fIn = new FileInputStream(fileName); byte[] buffer = new byte[4096]; int length; while ((length = in.read(buffer)) > 0){ out.write(buffer, 0, length); } in.close(); out.flush(); } } for the moment i will just pass a fileName string to retrieve the file for testing now i am lost at what to do on the client side, i have a simple public class DownloadFilePanel extends Composite { public DownloadFilePanel(final YFUser user , final String fileName){ final Element downloadIframe = RootPanel.get("__download").getElement(); VerticalPanel content = new VerticalPanel(); content.add(new Label("Download For this File : " + fileName)); Button button = new Button("Download"); button.addClickHandler(new ClickHandler(){ @Override public void onClick(ClickEvent event) { // i do not know what to do here }); content.add(button); initWidget(content); } } above is a simple widget that will supply a panel that will allow for the download of a file based on a fileName as you can see above, i do not know what to do to be able to download the file is there any one that can point me in the right direction?

  • Three ways to upload/post/convert iMovie to YouTube

    - by user44251
    For Mac users, iMovie is probably a convenient tool for making, editing their own home movies so as to upload to YouTube for sharing with more people. However, uploading iMovie files to YouTube can't be always a smooth run, I did notice many people complaining about it. This article is delivered for guiding those who are haunted by the nightmare by providing three common ways to upload iMovie files to YouTube. YouTube and iMovie YouTube is the most popular video sharing website for users to upload, share and view videos. It empowers anyone with an Internet connection the ability to upload video clips and share them with friends, family and the world. Users are invited to leave comments, pick favourites, send messages to each other and watch videos sorted into subjects and channels. YouTube accepts videos uploaded in most container formats, including WMV (Windows Media Video), 3GP (Cell Phones), AVI (Windows), MOV (Mac), MP4 (iPod/PSP), FLV (Adobe Flash), MKV (H.264). These include video codecs such as MP4, MPEG and WMV. iMovie is a common video editing software application comes with every Mac for users to edit their own home movies. It imports video footage to the Mac using either the Firewire interface on most MiniDV format digital video cameras, the USB port, or by importing the files from a hard drive where users can edit the video clips, add titles, and add music. Since 1999, eight versions of iMovie have been released by Apple, each with its own functions and characteristic, and each of them deal with videos in a way more or less different. But the most common formats handled with iMovie if specialty discarded as far as to my research are MOV, DV, HDV, MPEG-4. Three ways for successful upload iMovie files to YouTube Solution one and solution two suitable for those who are 100 certainty with their iMovie files which are fully compatible with YouTube. For smooth uploading, you are required to get a YouTube account first. Solution 1: Directly upload iMovie to YouTube Step 1: Launch iMovie, select the project you want to upload in YouTube. Step 2: Go to the file menu, click Share, select Export Movie Step 3: Specify the output file name and directory and then type the video type and video size. Solution 2: Post iMovie to YouTube straightly Step 1: Launch iMovie, choose the project you want to post in YouTube Step 2: From the Share menu, choose YouTube Step 3: In the pop-up YouTube windows, specify the name of your YouTube account, the password, choose the Category and fill in the description and tags of the project. Tick Make this movie more private on the bottom of the window, if possible, to limit those who can view the project. Click Next, and then click Publish. iMovie will automatically export and upload the movie to YouTube. Step 4: Click Tell a Friend to email friends and your family about your film. You are also allowed to copy the URL from Tell a Friend window and paste it into an email you created in your favourite email application if you like. Anyone you send to email to will be able to follow the URL directly to your movie. Note: Videos uploaded to YouTube are limited to ten minutes in length and a file size of 2GB. Solution 3: Upload to iMovie after conversion If neither of the above mentioned method works, there is still a third way to turn to. Sometimes, your iMovie files may not be recognized by YouTube due to the versions of iMovie (settings and functions may varies among versions), video itself (video format difference because of file extension, resolution, video size and length), compatibility (videos that are completely incompatible with YouTube). In this circumstance, the best and reliable method is to convert your iMovie files to YouTube accepted files, iMovie to YouTube converter will be inevitably the ideal choice. iMovie to YouTube converter is an elaborately designed tool for convert iMovie files to YouTube workable WMV, 3GP, AVI, MOV, MP4, FLV, MKV for smooth uploading with hard-to-believe conversion speed and second to none output quality. It can also convert between almost all popular popular file formats like AVI, WMV, MPG, MOV, VOB, DV, MP4, FLV, 3GP, RM, ASF, SWF, MP3, AAC, AC3, AIFF, AMR, WAV, WMA etc so as to put on various portable devices, import to video editing software or play on vast amount video players. iMovie to YouTube converter can also served as an excellent video editing tool to meet your specific program requirements. For example, you can cut your video files to a certain length, or split your video files to smaller ones and select the proper resolution suitable for demands of YouTube by Clip or Settings separately. Crop allows you to cut off unwanted black edges from your videos. Besides, you can also have a good command of the whole process or snapshot your favourite pictures from the preview window. More can be expected if you have a try.

  • Diagramming Software for a Developer/Designer

    - by Craig Walker
    For a long time I've been looking for a good diagramming/vector-based drawing program that meets my needs as a developer. I'd like to: Draw database diagrams Draw flow charts Draw object-modeling diagrams (UML being the standard) Draw other free-form diagrams (basically boxes & arrows with the occasional clipart) Draw mockups of user interfaces and web pages EDIT: I want good-looking electronic-format diagrams that I can show to 3rd parties, not just something for my own internal use. EDIT 2: I'm also looking for Windows software, although I'm toying with the idea of switching to Mac, so a really good Mac-only product might get me to switch. Basically I need a good vector graphic program (with decent grouping, connecting lines, and ideally auto-routing). I'd prefer a diagramming tool that can also be used for drawing (for the UI mockups) rather than a drawing tool that can also be used for diagrams. I've tried Visio on several occasions, and every time I've been disappointed. The interface always seems to get in my way at some point. It's pretty close to what I want, and the latest version (I got the trail from MS) seems to be better than previous ones in terms of usability, but I really don't want to plunk down that sort of cash for a mediocre product. I've tried Dia and Inkscape, and while initially promising and with the right price tag, I found both of them to be lacking in several ways (including some recurring bugs). I've toyed with getting Adobe Illustrator, but I've never used it before, and I have a feeling that it wouldn't handle the diagramming aspect very well, and I don't want to buy a copy just to find out it doesn't meet my needs. So far, the product that I've had the most success with is, sadly, OpenOffice Draw. It's free of course (which lowers my expectations and thus improves my view of it) and its usability is pretty good, but in the end I'd like something more suited to diagramming. I'm willing to spend real money (in the $500-$1K range) for a really good piece of software if it does everything I want it to. The front runner is of course Visio but I'm hoping for more. Does anybody have any recommendations? CONCLUSION: @dlamblin had the most informative post, but the part I gained the most from was his/her (and others) mention of OmniGraffle, not Gliffy. I gave Gliffy a try, and it seemed neet for occational use, but since it's a Flash app (note: not AJAX as dlamblin mentioned) it's still a bit of a pain to use (no keyboard shortcuts for copy/paste was pretty much a deal breaker for me). I also tried SmartDraw, but it had 3-strikes-you're-out against it: The trial period was only 7 days long. It used some nonstandard (and visually jarring) GUI widget toolkit for its UI. At the very least it makes me suspicious (how do I know it will actually work & support the standard Windows features?) It crashed on me early into my trial. OmniGraffle looks like exactly what I want... except that it's Mac-only (so I couldn't give it a try). However, it got good reviews from my Mac-owning coworker, and I hope to try it on a friend's Mac soon. If it's good enough then I might spring for a new MacBook.

  • ASP.NET MVC Consume JSONResult in Bing Maps API

    - by rockinthesixstring
    I know there are a few topics on this, but I seem to be fumbling my way through with no results. I'm trying to use a controller to return JSON results to my Bin Maps functions. Here's what I have for my controller (yes it is properly returning JSON data. Function Regions() As JsonResult Dim rj As New List(Of RtnJson)() rj.Add(New RtnJson("135 Bow Meadows Drive, Cochrane, Alberta", "desc", "title")) rj.Add(New RtnJson("12 Bowridge Dr NW, Calgary, Alberta, Canada", "desc2", "title2")) Return Json(rj, JsonRequestBehavior.AllowGet) End Function Then in my script I have this, but it's not working. <script type="text/javascript"> var map = null; var centerLat = 51.045 ; var centerLon = -114.05722; var json_object = $.getJSON("<%: Url.Action("Regions", "Events")%>"); function LoadMap() { map = new VEMap('bingMap'); map.LoadMap(new VELatLong(centerLat, centerLon), 10); $.each(json_object, function () { alert(this.address); //this alert is returning "address is undefined" StartGeocoding(this.address, this.title, this.desc); }); } function StartGeocoding(address, title, desc) { map.Find(null, // what address, // where null, // VEFindType (always VEFindType.Businesses) null, // VEShapeLayer (base by default) null, // start index for results (0 by default) null, // max number of results (default is 10) null, // show results?

  • Using XMLDecoder to cast Encoded XML to List<>

    - by Ender
    I am writing an application that reads in a large number of basic user details in the following format; once read in it then allows the user to search for a user's details using their email: NAME ROLE EMAIL --------------------------------------------------- Joe Bloggs Manager [email protected] John Smith Consultant [email protected] Alan Wright Tester [email protected] ... The problem I am suffering is that I need to store a large number of details of all people that have worked at the company. The file containing these details will be written on a yearly basis simply for reporting purposes, but the program will need to be able to access these details quickly. The way I aim to access these files is to have a program that asks the user for the name of the unique email of the member of staff and for the program to then return the name and the role from that line of the file. I've played around with text files, but am struggling with how I would handle multiple columns of data when it comes to searching this large file. What is the best format to store such data in? A text file? XML? The size doesn't bother me, but I'd like to be able to search it as quickly as possible. The file will need to contain a lot of entries, probably over the 10K mark over time. EDIT: I've decided to go with the XML serialisation method. I've managed to get the code for Encoding working perfectly, but the Decoding code below does not work. XMLDecoder d = new XMLDecoder( new BufferedInputStream(new FileInputStream("data.xml"))); List<Employee> list = (List<Employee>) d.readObject(); d.close(); for(Employee x : list) { if(x.getEmail().equals(userInput)) { // do stuff } } When the program hits List<Employee> list = (List<Employee>) d.readObject(); an exception is thrown claiming that "Employee cannot be cast to java.util.List". I've added a bounty to this and anyone that can help me solve this problem once and for all will get lots of lovely points. EDIT 2: I've looked a bit more into the problem and have come across Serialization as a potential answer. If anyone can look into this for me as I've no experience with Serialization or Deserialization I'd be very grateful. It can provide an Object with no problems whatsoever, but I really need to return it in the same format as it went in (List). EDIT 3: Ugh, this problem is really starting to drive me crazy and to be honest I'm starting to think that it's an unsolvable problem. If possible, could someone take a look at the code and help provide a solution for me?

  • progressIndicator does not update till about 10 seconds after awakeFromNib occures

    - by theprojectabot
    I have been trying to get this one section of my UI to immediatly up date when the document loads into view. The awakeFromNib fires the pasted code and then starts a timer to repeat every 10 seconds... I load a default storage location: ~/Movies... which shows up immediately.. yet the network location that is saved in the document that gets pulled from the XML only seems to show up after the second firing of the - (void)updateDiskSpaceDisplay timer. I have set breakpoints and know that the ivars that contain the values that are being put into the *fileSystemAttributes is the network location right when the awakeFromNib occurs... Im confused why it magically appears after the second time firing instead of immediately displaying the write values. - (void)updateDiskSpaceDisplay { // Obtain information about the file system used on the selected storage path. NSError *error = NULL; NSDictionary *fileSystemAttributes = [[NSFileManager defaultManager] attributesOfFileSystemForPath:[[[self settings] containerSettings] storagePath] error:&error]; if( !fileSystemAttributes ) return; // Get the byte capacity of the drive. long long byteCapacity = [[fileSystemAttributes objectForKey:NSFileSystemSize] unsignedLongLongValue]; // Get the number of free bytes. long long freeBytes = [[fileSystemAttributes objectForKey:NSFileSystemFreeSize] unsignedLongLongValue]; // Update the level indicator, and the text fields to show the current information. [totalDiskSpaceField setStringValue:[self formattedStringFromByteCount:byteCapacity]]; [totalDiskSpaceField setNeedsDisplay:YES]; [usedDiskSpaceField setStringValue:[self formattedStringFromByteCount:(byteCapacity - freeBytes)]]; [usedDiskSpaceField setNeedsDisplay:YES]; [diskSpaceIndicator setMaxValue:100]; [diskSpaceIndicator setIntValue:(((float) (byteCapacity - freeBytes) / (float) byteCapacity) * 100.0)]; [diskSpaceIndicator display:YES]; } thoughts? my awakeFromNib: - (void)awakeFromNib { [documentWindow setAcceptsMouseMovedEvents:YES]; [documentWindow setDelegate:self]; [self updateSettingsDisplay]; [self updateDiskSpaceDisplay]; [self setDiskSpaceUpdateTimer:[NSTimer scheduledTimerWithTimeInterval:10.0 target:self selector:@selector(updateDiskSpaceDisplay) userInfo:NULL repeats:YES]]; [self setUpClipInfoTabButtons]; [self performSelector:@selector(setupEngineController) withObject:NULL afterDelay:0.1]; }

  • Strategy and AI for the game 'Proximity'

    - by smci
    'Proximity' is a strategy game of territorial domination similar to Othello, Go and Risk. Two players, uses a 10x12 hex grid. Game invented by Brian Cable in 2007. Seems to be a worthy game for discussing a) optimal strategy then b) how to build an AI Strategies are going to be probabilistic or heuristic-based, due to the randomness factor, and the high branching factor (starts out at 120). So it will be kind of hard to compare objectively. A compute time limit of 5s per turn seems reasonable. Game: Flash version here and many copies elsewhere on the web Rules: here Object: to have control of the most armies after all tiles have been placed. Each turn you received a randomly numbered tile (value between 1 and 20 armies) to place on any vacant board space. If this tile is adjacent to any ally tiles, it will strengthen each tile's defenses +1 (up to a max value of 20). If it is adjacent to any enemy tiles, it will take control over them if its number is higher than the number on the enemy tile. Thoughts on strategy: Here are some initial thoughts; setting the computer AI to Expert will probably teach a lot: minimizing your perimeter seems to be a good strategy, to prevent flips and minimize worst-case damage like in Go, leaving holes inside your formation is lethal, only more so with the hex grid because you can lose armies on up to 6 squares in one move low-numbered tiles are a liability, so place them away from your main territory, near the board edges and scattered. You can also use low-numbered tiles to plug holes in your formation, or make small gains along the perimeter which the opponent will not tend to bother attacking. a triangle formation of three pieces is strong since they mutually reinforce, and also reduce the perimeter Each tile can be flipped at most 6 times, i.e. when its neighbor tiles are occupied. Control of a formation can flow back and forth. Sometimes you lose part of a formation and plug any holes to render that part of the board 'dead' and lock in your territory/ prevent further losses. Low-numbered tiles are obvious-but-low-valued liabilities, but high-numbered tiles can be bigger liabilities if they get flipped (which is harder). One lucky play with a 20-army tile can cause a swing of 200 (from +100 to -100 armies). So tile placement will have both offensive and defensive considerations. Comment 1,2,4 seem to resemble a minimax strategy where we minimize the maximum expected possible loss (modified by some probabilistic consideration of the value ß the opponent can get from 1..20 i.e. a structure which can only be flipped by a ß=20 tile is 'nearly impregnable'.) I'm not clear what the implications of comments 3,5,6 are for optimal strategy. Interested in comments from Go, Chess or Othello players. (The sequel ProximityHD for XBox Live, allows 4-player -cooperative or -competitive local multiplayer increases the branching factor since you now have 5 tiles in your hand at any given time, of which you can only play one. Reinforcement of ally tiles is increased to +2 per ally.)

  • PHP script keeps doing mmap/munmap

    - by Aurélien Momow
    Hello, My PHP script contains a loop, which does nothing much more than echoing and dereferencing pointers (like in $tab[$othertab[$i]]- stuff). It was working great until yesterday, when this script starting being VERY slow (like 50 times slower than before). After using strace, i figured out that 90% of the time, the script does mmap/munmap.

  • What is the coolest thing you can do in <10 lines of simple code? Help me inspire beginners!

    - by Tom Ritter
    I'm looking for the coolest thing you can do in a few lines of simple code. I'm sure you can write a Mandelbrot set in Haskell in 15 lines but it's difficult to follow. My goal is to inspire students that programming is cool. We know that programming is cool because you can create anything you imagine - it's the ultimate creative outlet. I want to inspire these beginners and get them over as many early-learning humps as I can. Now, my reasons are selfish. I'm teaching an Intro to Computing course to a group of 60 half-engineering, half business majors; all freshmen. They are the students who came from underprivileged High schools. From my past experience, the group is generally split as follows: a few rock-stars, some who try very hard and kind of get it, the few who try very hard and barely get it, and the few who don't care. I want to reach as many of these groups as effectively as I can. Here's an example of how I'd use a computer program to teach: Here's an example of what I'm looking for: a 1-line VBS script to get your computer to talk to you: CreateObject("sapi.spvoice").Speak InputBox("Enter your text","Talk it") I could use this to demonstrate order of operations. I'd show the code, let them play with it, then explain that There's a lot going on in that line, but the computer can make sense of it, because it knows the rules. Then I'd show them something like this: 4(5*5) / 10 + 9(.25 + .75) And you can see that first I need to do is (5*5). Then I can multiply for 4. And now I've created the Object. Dividing by 10 is the same as calling Speak - I can't Speak before I have an object, and I can't divide before I have 100. Then on the other side I first create an InputBox with some instructions for how to display it. When I hit enter on the input box it evaluates or "returns" whatever I entered. (Hint: 'oooooo' makes a funny sound) So when I say Speak, the right side is what to Speak. And I get that from the InputBox. So when you do several things on a line, like: x = 14 + y; You need to be aware of the order of things. First we add 14 and y. Then we put the result (what it evaluates to, or returns) into x. That's my goal, to have a bunch of these cool examples to demonstrate and teach the class while they have fun. I tried this example on my roommate and while I may not use this as the first lesson, she liked it and learned something. Some cool mathematica programs that make beautiful graphs or shapes that are easy to understand would be good ideas and I'm going to look into those. Here are some complicated actionscript examples but that's a bit too advanced and I can't teach flash. What other ideas do you have?

  • Flex Builder debug problem

  • Find optimal strategy and AI for the game 'Proximity'?

    - by smci
    'Proximity' is a strategy game of territorial domination similar to Othello, Go and Risk. Two players, uses a 10x12 hex grid. Game invented by Brian Cable in 2007. Seems to be a worthy game for discussing a) optimal algorithm then b) how to build an AI. Strategies are going to be probabilistic or heuristic-based, due to the randomness factor, and the insane branching factor (20^120). So it will be kind of hard to compare objectively. A compute time limit of 5s per turn seems reasonable. Game: Flash version here and many copies elsewhere on the web Rules: here Object: to have control of the most armies after all tiles have been placed. Each turn you received a randomly numbered tile (value between 1 and 20 armies) to place on any vacant board space. If this tile is adjacent to any ally tiles, it will strengthen each tile's defenses +1 (up to a max value of 20). If it is adjacent to any enemy tiles, it will take control over them if its number is higher than the number on the enemy tile. Thoughts on strategy: Here are some initial thoughts; setting the computer AI to Expert will probably teach a lot: minimizing your perimeter seems to be a good strategy, to prevent flips and minimize worst-case damage like in Go, leaving holes inside your formation is lethal, only more so with the hex grid because you can lose armies on up to 6 squares in one move low-numbered tiles are a liability, so place them away from your main territory, near the board edges and scattered. You can also use low-numbered tiles to plug holes in your formation, or make small gains along the perimeter which the opponent will not tend to bother attacking. a triangle formation of three pieces is strong since they mutually reinforce, and also reduce the perimeter Each tile can be flipped at most 6 times, i.e. when its neighbor tiles are occupied. Control of a formation can flow back and forth. Sometimes you lose part of a formation and plug any holes to render that part of the board 'dead' and lock in your territory/ prevent further losses. Low-numbered tiles are obvious-but-low-valued liabilities, but high-numbered tiles can be bigger liabilities if they get flipped (which is harder). One lucky play with a 20-army tile can cause a swing of 200 (from +100 to -100 armies). So tile placement will have both offensive and defensive considerations. Comment 1,2,4 seem to resemble a minimax strategy where we minimize the maximum expected possible loss (modified by some probabilistic consideration of the value ß the opponent can get from 1..20 i.e. a structure which can only be flipped by a ß=20 tile is 'nearly impregnable'.) I'm not clear what the implications of comments 3,5,6 are for optimal strategy. Interested in comments from Go, Chess or Othello players. (The sequel ProximityHD for XBox Live, allows 4-player -cooperative or -competitive local multiplayer increases the branching factor since you now have 5 tiles in your hand at any given time, of which you can only play one. Reinforcement of ally tiles is increased to +2 per ally.)

  • Problem with socket communication between C# and Flex

    - by Chris Lee
    Hi all, I am implementing a simulated b/s stock data system. I am using flex and c# for client and server sides. I found flash has a security policy and I handled the policy-file-request in my server code. But seems it doesn't work, because the code jumped out at "socket.Receive(b)" after connection. I've tried sending message on client in the connection handler, in that case the server can receive correct message. But the auto-generated "policy-file-request" can never be received, and the client can get no data sending from server. Here I put my code snippet. my ActionScript code: public class StockClient extends Sprite { private var hostName:String = "192.168.84.103"; private var port:uint = 55555; private var socket:XMLSocket; public function StockClient() { socket = new XMLSocket(); configureListeners(socket); socket.connect(hostName, port); } public function send(data:Object) : void{ socket.send(data); } private function configureListeners(dispatcher:IEventDispatcher):void { dispatcher.addEventListener(Event.CLOSE, closeHandler); dispatcher.addEventListener(Event.CONNECT, connectHandler); dispatcher.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler); dispatcher.addEventListener(ProgressEvent.PROGRESS, progressHandler); dispatcher.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler); dispatcher.addEventListener(ProgressEvent.SOCKET_DATA, dataHandler); } private function closeHandler(event:Event):void { trace("closeHandler: " + event); } private function connectHandler(event:Event):void { trace("connectHandler: " + event); //following testing message can be received, but client can't invoke data handler //send("<policy-file-request/>"); } private function dataHandler(event:ProgressEvent):void { //never fired trace("dataHandler: " + event); } private function ioErrorHandler(event:IOErrorEvent):void { trace("ioErrorHandler: " + event); } private function progressHandler(event:ProgressEvent):void { trace("progressHandler loaded:" + event.bytesLoaded + " total: " + event.bytesTotal); } private function securityErrorHandler(event:SecurityErrorEvent):void { trace("securityErrorHandler: " + event); } } my C# code: const int PORT_NUMBER = 55555; const String BEGIN_REQUEST = "begin"; const String END_REQUEST = "end"; const String POLICY_REQUEST = "<policy-file-request/>\u0000"; const String POLICY_FILE = "<?xml version=\"1.0\"?>\n" + "<!DOCTYPE cross-domain-policy SYSTEM \"http://www.adobe.com/xml/dtds/cross-domain-policy.dtd\">\n" + "<cross-domain-policy> \n" + " <allow-access-from domain=\"*\" to-ports=\"55555\"/> \n" + "</cross-domain-policy>\u0000"; ................ private void startListening() { provider = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); provider.Bind(new IPEndPoint(IPAddress.Parse("192.168.84.103"), PORT_NUMBER)); provider.Listen(10); isListened = true; while (isListened) { Socket socket = provider.Accept(); Console.WriteLine("connect!"); byte[] b = new byte[1024]; int receiveLength = 0; try { // code jump out at this statement receiveLength = socket.Receive(b); } catch (Exception e) { Debug.WriteLine(e.ToString()); } String request = System.Text.Encoding.UTF8.GetString(b, 0, receiveLength); Console.WriteLine("request:"+request); if (request == POLICY_REQUEST) { socket.Send(Encoding.UTF8.GetBytes(POLICY_FILE)); Console.WriteLine("response:" + POLICY_FILE); } else if (request == END_REQUEST) { Dispose(socket); } else { StartSocket(socket); break; } } } Sorry for the long code, please someone help with it, thanks a million

  • Offline backup synchronization

    - by Pavan Kumar
    There is a Central Server running Windows Server 2003 and SQL Server 2005 and there are 7 client machines situated in various places and has XP Pro & SQL Server 2005 installed in all of them. They are not interconnected so they are physically seperate. One person goes to each of these centers maybe twice a month and takes the backup (Full database consisting of mdf and ldf files) with a pen drive and brings it to the Central server which contains the central database holding same schema as all the other client databases. I need to synchronize each backup database (belonging to different centers) one by one to update the existing data or inserting new data in the central database . The solution i got was Replication. The pendrive is brought to central server consisting of 7 instances of the databases and then the databases is attached to the central server one by one to the same SQL Server where the central database exists. Then my idea was to replicate the backup database one by one i.e using single subscription (Central Database) and multiple publication ( i.e 7 instances of databases in my case) toplogy by performing replication locally (i.e in the same machine). So i tried to develop a UI in C# .Net to programatically run the Transactional Replication with push subscription using RMO Programming (which is incomplete as of now because there is no point in developing when you already know it is not the solution). Transactional Replication can either be set to initialize with a snapshot or without a snapshot. If i go for the first option i.e with a snapshot , the data whatever is present in Central Database is overwritten by the new data . So the data present initially in the central database is lost. If i try to initialize without snapshot , no data (the data already has the updated and new data) will be sent from the backup database to server. The replication will work in a scenario where any incremental changes is done only after you set the replication . So the initial data whatever was present in the backup database when setting up the replication will not be replicated when running the snapshot agent for the first time to synchronize. Only changes in the backup database thereafter will be reflected to the central database .(Remember I am not going to insert new data or make any changes to the backup database after i attach it to the Central Server. ) So this solution is not feasible. I want a solution for synchronizing from one client database to central database present in the same machine using C#.NET. If you can provide me small example maybe with two databases(with same schema) DB1(Client) to DB2(Server) consisting of one or two tables it will be very helpful. The synchronization is not bidirectional.I want to only update existing data or insert new data from DB1 to DB2 (DB2 may contain some data initially). Thanks and Regards Pavan

  • Three ways to upload/post/convert iMovie to YouTube [closed]

    - by alexyu2010
    For Mac users, iMovie is probably a convenient tool for making, editing their own home movies so as to upload to YouTube for sharing with more people. However, uploading iMovie files to YouTube can't be always a smooth run, I did notice many people complaining about it. This article is delivered for guiding those who are haunted by the nightmare by providing three common ways to upload iMovie files to YouTube. YouTube and iMovie YouTube is the most popular video sharing website for users to upload, share and view videos. It empowers anyone with an Internet connection the ability to upload video clips and share them with friends, family and the world. Users are invited to leave comments, pick favourites, send messages to each other and watch videos sorted into subjects and channels. YouTube accepts videos uploaded in most container formats, including WMV (Windows Media Video), 3GP (Cell Phones), AVI (Windows), MOV (Mac), MP4 (iPod/PSP), FLV (Adobe Flash), MKV (H.264). These include video codecs such as MP4, MPEG and WMV. iMovie is a common video editing software application comes with every Mac for users to edit their own home movies. It imports video footage to the Mac using either the Firewire interface on most MiniDV format digital video cameras, the USB port, or by importing the files from a hard drive where users can edit the video clips, add titles, and add music. Since 1999, eight versions of iMovie have been released by Apple, each with its own functions and characteristic, and each of them deal with videos in a way more or less different. But the most common formats handled with iMovie if specialty discarded as far as to my research are MOV, DV, HDV, MPEG-4. Three ways for successful upload iMovie files to YouTube Solution one and solution two suitable for those who are 100 certainty with their iMovie files which are fully compatible with YouTube. For smooth uploading, you are required to get a YouTube account first. Solution 1: Directly upload iMovie to YouTube Step 1: Launch iMovie, select the project you want to upload in YouTube. Step 2: Go to the file menu, click Share, select Export Movie Step 3: Specify the output file name and directory and then type the video type and video size. Solution 2: Post iMovie to YouTube straightly Step 1: Launch iMovie, choose the project you want to post in YouTube Step 2: From the Share menu, choose YouTube Step 3: In the pop-up YouTube windows, specify the name of your YouTube account, the password, choose the Category and fill in the description and tags of the project. Tick Make this movie more private on the bottom of the window, if possible, to limit those who can view the project. Click Next, and then click Publish. iMovie will automatically export and upload the movie to YouTube. Step 4: Click Tell a Friend to email friends and your family about your film. You are also allowed to copy the URL from Tell a Friend window and paste it into an email you created in your favourite email application if you like. Anyone you send to email to will be able to follow the URL directly to your movie. Note: Videos uploaded to YouTube are limited to ten minutes in length and a file size of 2GB. Solution 3: Upload to iMovie after conversion If neither of the above mentioned method works, there is still a third way to turn to. Sometimes, your iMovie files may not be recognized by YouTube due to the versions of iMovie (settings and functions may varies among versions), video itself (video format difference because of file extension, resolution, video size and length), compatibility (videos that are completely incompatible with YouTube). In this circumstance, the best and reliable method is to convert your iMovie files to YouTube accepted files, iMovie to YouTube converter will be inevitably the ideal choice. iMovie to YouTube converter is an elaborately designed tool for convert iMovie files to YouTube workable WMV, 3GP, AVI, MOV, MP4, FLV, MKV for smooth uploading with hard-to-believe conversion speed and second to none output quality. It can also convert between almost all popular popular file formats like AVI, WMV, MPG, MOV, VOB, DV, MP4, FLV, 3GP, RM, ASF, SWF, MP3, AAC, AC3, AIFF, AMR, WAV, WMA etc so as to put on various portable devices, import to video editing software or play on vast amount video players. iMovie to YouTube converter can also served as an excellent video editing tool to meet your specific program requirements. For example, you can cut your video files to a certain length, or split your video files to smaller ones and select the proper resolution suitable for demands of YouTube by Clip or Settings separately. Crop allows you to cut off unwanted black edges from your videos. Besides, you can also have a good command of the whole process or snapshot your favourite pictures from the preview window. More can be expected if you have a try.

  • c#: exporting swf object as image to Word

    Hello in my Asp.net web page (C# on backend) I use a Repeater, whose items consist of a title and a Flex chart (embedded .swf file). I am trying to export the contents of the Repeater to a Word document. My problem is to convert the SWF files into images and pass it on to the Word document.
