  • IntelliJ and internationalisation: accented characters

    - by skiaddict1
    I have a java application which has a GUI in both English and French, using the standard Java internationalisation services. I wrote it in JBuilder 2005 on an old machine, and recently upgraded, which has meant changing IDEs. I have finally settled on IntelliJ, which I adore. However, it doesn't seem able to handle the accented characters in my ListResourceBundle descendants which contain French. When I first created the IntelliJ project and added my source (which I did manually, to be sure nothing weird was going on behind the scenes), I noticed that all the accented characters had been changed into pairs of characters such as v©. I went through the code and corrected all of these, and assumed that the problem was fixed. But I find on running the (rebuilt) project that the pairs of characters are still showing, instead of the accented characters that I see in my code!! Can someone who has done internationalisation in IntelliJ please tell me what I need to do to fix this? Grateful TIA! PS I'm on the Mac, BTW

  • Ideal way to deliver large data over Web Services

    - by zengr
    We are trying to design 6 web services, which will serve another client component. The client component requires data from the web service we are implementing. Now, the problem is, there is not 1 WS we are implementing, there is one WS which the client component hits, this initiates a series (5 more) of WSs which gather data from their respective data stores and finally provide the data back to the original WS, which then delivers the data back to the client component. So, if the requested data becomes huge, then, this will be a serious problem for our internal communication channel. So, what do you guys suggest? What can be done to avoid overloading of the communication channel between the internal WS and at the same time, also delivering the data to the client component.

  • Compressing three individual jpeg pics containing temporal redundancy?

    - by michael
    I am interfacing and embedded device with a camera module that returns a single jpeg compressed frame each time I trigger it. I would like to take three successive shots (approx 1 frame per 1/4 second) and further compress the images into a single file. The assumption here is that there is a lot of temporal redundancy, therefore lots of room for more compression across the three frames (compared to sending three separate jpeg images). I will be implementing the solution on an embedded device in C without any libraries and no OS. The camera will be taking pics in an area with very little movement (no visitors or screens in the background, maybe a tree with swaying branches), so I think my assumption about redundancy is pretty solid. When the file is finally viewed on a pc/mac, I don't mind having to write something to extract the three frames (so it can be a nonstandard cluge) So I guess the actual question is: What is the best way to compress these three images together given the fact that they are already in JPEG format (it is a possibly to convert back to a raw image, but if i dont have too...)

  • Listing time every second as a Bash script

    - by Caleb
    Hello all, first time here as I've finally started to learn programming. Anyway, I'm just trying to print the time in nanoseconds every second here, and I have this: #!/usr/bin/env bash while true; do date=(date +%N) ; echo $date ; sleep 1 ; done Now, that simply yields a string of date's, which isn't what I want. My learning has been rather messy, so I hope you'll excuse me for this if it's really simple. Also, I did manage to fine this, that worked on the prompt: while true ; do date +%N ; sleep 1 ; done But that obviously doesn't work as a script.

  • Where to Start with build a personal site and WordPress, CSS and CMS

    - by Simon
    Hey guys im in a very confused state of mind at the moment and need some help with Word Press and generally starting a website. My parents have had a business for 20 years and have finally decided to get a website! As im studying IT and Business i said id get it done for them. Rather than design it from scratch i used a template which i bought from themeforest.net (awesome template!) and yesterday a friend mentioned in passing using word press as a CMS which i had never heard of before, and he left before i could ask any questions. SO basically i have a site working on my computer and i have no idea how to get it live as a .com or .com.au, so far as i can see wordpress is a blog with .wordpress.com which isnt what im looking for. Thanks in advance Simon

  • CSS border and the :hover dynamic pseudo-class

    - by dbasch
    Hi All, I have built a persistent dropline menu with two levels using only CSS. It is pretty standard. It is a nested set of UL's and the UL's :hover state is what shows and hides the sub menu levels. Something like this: | *Pets* | Colors | Cars | | Cats | Dogs | Birds| Goats | Sheep | | Pets | *Colors* | Cars | | Red | Orange | Green | Blue| Yellow | I then added a 1px border at the bottom of the first level UL element. Like this: | *Pets* | Colors | Cars | -------------------------------------- | Cats | Dogs | Birds| Goats | Sheep | When I hover over a first level item (Pets), and then move the mouse down to the second level (Cats), the entire second level disappears. I finally figured out that the UL's 1px border is not included in the hover area for the UL. Can I add a border to the bottom of a dropline menu level without messing up the menu hovering? Thanks!

  • FreeLibrary vs implicit unloading DLL

    - by Adil
    I have implemented a DLL including DllMain() entry function:- BOOL APIENTRY DllMain( HMODULE hModule, DWORD ul_reason_for_call, LPVOID lpReserved ) { case DLL_PROCESS_ATTACH: ... case DLL_THREAD_ATTACH: ... case DLL_THREAD_DETACH: ... case DLL_PROCESS_DETACH: ... } Unfortunately i made a mistake in DLL_PROCESS_DETACH case and accessing illegal memorey (access violation). I made a sample program which loads the library using LoadLibrary() function, uses the library function and finally call FreeLibrary() and return. When i executed this program, i didnt get any error message. But if i remove FreeLibrary(), in that case the DLL_PROCESS_DETACH case is executed implicitly and this time it gives error dialog box mentioning that there is access violation. Why calling FreeLibrary() suppress this error? OR internally it handles this exception? What is suggested way.

  • Handling newline character in input between Windows and Linux

    - by Fazal
    I think this is a standard problem which may have been asked before but I could not get the exact answer so posting the issue. The issue is that our server is running on a linux box. We access the server over the browser on a window box to enter data into field which is supposed to contain multiple lines which user can enter by pressing the enter key after each line Abc Def GHI When this input field (this is a text area),is read on the linux machine, we want to split the data based on new line character. I had three question on this. Does the incoming data contain "\r\n" or "\n" If incoming data does contain "\r\n", the linux line.separator property (vm property) would not work for me as it would say "\n" and therefore may leave "\r" in the data. If "\r" is left in the data, if I open the file on a windows machine, will this mean a newline character? Finally can anyone tell me the standard way to deal with this issue?

  • Draw a textured triangle (patch) in Matlab

    - by Petter
    I have a triangle in (u,v) coordinates in an image. I would like to draw this triangle at 3D coordinates (X,Y,Z) texture-mapped with the triangle in the image. Here, u,v,X,Y,Z are all vectors with three elements representing the three corners of the triangle. I have a very ugly, slow and insatisfactory solution in which I (1) extract a rectangular part of the image, (2) transform it to 3D space with the transformation defined by the three points, (3) draw it with surface, and (4) finally masking out everything that is not part of the triangle with AlphaData. Surely there must be an easier way of doing this?

  • A very basic auto-expanding list/array

    - by MainMa
    Hi, I have a method which returns an array of fixed type objects (let's say MyObject). The method creates a new empty Stack<MyObject>. Then, it does some work and pushes some number of MyObjects to the end of the Stack. Finally, it returns the Stack.ToArray(). It does not change already added items or their properties, nor remove them. The number of elements to add will cost performance. There is no need to sort/order the elements. Is Stack a best thing to use? Or must I switch to Collection or List to ensure better performance and/or lower memory cost?

  • Limit Connections with semaphores

    - by Robert
    I'm trying to limit the number of connections my server will accept using semaphores, but when running, my code doesn't seem to make this restriction - am I using the semaphore correctly? eg. I have hardcoded the number of permit as 2, but I can connect an unlimited number of clients... public class EServer implements Runnable { private ServerSocket serverSocket; private int numberofConnections = 0; private Semaphore sem = new Semaphore(2); private volatile boolean keepProcessing = true; public EServer(int port) throws IOException { serverSocket = new ServerSocket(port); } @Override public void run() { while (keepProcessing) { try { sem.acquire(); Socket socket = serverSocket.accept(); process(socket, getNextConnectionNumber()); } catch (Exception e) { } finally { sem.release(); } } closeIgnoringException(serverSocket); } private synchronized int getNextConnectionNumber() { return ++numberofConnections; } // processing related methods }

  • Read only particular fields from CSV File in vb.net

    - by fireBand
    Hi, I have this code to read a CVS file. It reads each line, devides each line by delimiter ',' and stored the field values in array 'strline()' . How do I extract only required fields from the CSV file? For example if I have a CSV File like Type,Group,No,Sequence No,Row No,Date (newline) 0,Admin,3,345678,1,26052010 (newline) 1,Staff,5,78654,3,26052010 I Need only the value of columns Group,Sequence No and date. Thanks in advance for any ideas. Dim myStream As StreamReader = Nothing ' Hold the Parsed Data Dim strlines() As String Dim strline() As String Try myStream = File.OpenText(OpenFile.FileName) If (myStream IsNot Nothing) Then ' Hold the amount of lines already read in a 'counter-variable' Dim placeholder As Integer = 0 strlines = myStream.ReadToEnd().Split(Environment.NewLine) Do While strlines.Length <> -1 ' Is -1 when no data exists on the next line of the CSV file strline = strlines(placeholder).Split(",") placeholder += 1 Loop End If Catch ex As Exception LogErrorException(ex) Finally If (myStream IsNot Nothing) Then myStream.Close() End If End Try

  • Java object caching, which is faster, reading from a file or from a remote machine?

    - by Kumar225
    I am at a point where I need to take the decision on what to do when caching of objects reaches the configured threshold. Should I store the objects in a indexed file (like provided by JCS) and read them from the file (file IO) when required or have the object stored in a distributed cache (network, serialization, deserialization) We are using Solaris as OS. ============================ Adding some more information. I have this question so as to determine if I can switch to distributed caching. The remote server which will have cache will have more memory and better disk and this remote server will only be used for caching. One of the problems we cannot increase the locally cached objects is , it stores the cached objects in JVM heap which has limited memory(using 32bit JVM). ======================================================================== Thanks, we finally ended up choosing Coherence as our Cache product. This provides many cache configuration topologies, in process vs remote vs disk ..etc.

  • How do these user/userParam references relate to the Customer and Account lookups?

    - by plath
    In the following code example how do the user/userParam references relate to the Customer and Account lookups and what is the relationship between Customer and Account? // PersistenceManager pm = ...; Transaction tx = pm.currentTransaction(); User user = userService.currentUser(); List<Account> accounts = new ArrayList<Account>(); try { tx.begin(); Query query = pm.newQuery("select from Customer " + "where user == userParam " + "parameters User userParam"); List<Customer> customers = (List<Customer>) query.execute(user); query = pm.newQuery("select from Account " + "where parent-pk == keyParam " + "parameters Key keyParam"); for (Customer customer : customers) { accounts.addAll((List<Account>) query.execute(customer.key)); } } finally { if (tx.isActive()) { tx.rollback(); } }

  • Skinning WinAPI Controls

    - by Brad
    If you've ever seen an application in the Adobe Creative Suite 5 (CS5), you may have noticed that it doesn't look like the native Windows GUI.. They have modified it to have a different look to it. Where would someone begin to make an application that has a custom skin? CS5 uses the Adobe Source library for it's widget/control management, so I tried downloading and compiling the Adobe Source Library to see if I could make a nice skinned app like Photoshop CS5, but after finally getting it to compile and tested it, I realized the library was only for managing widgets and not skinning the GUI, like CS5 has. Where would I begin to make a nice skinned program like Adobe Cs5 applications? Can anyone point me in the right direction? Do I simply use the WM_PAINT Message from WinAPI and render my own widgets using openGL or something?

  • ack (perl?) regexp matching lines where if is the first word

    - by Gauthier
    Hey. I'm finally learning regexps, training with ack. I believe this uses perl regexp. I want to match all lines where the first non-blank characters are if (<word> !, with any number of spaces in between the elements. This is what I came up with: ^[ \t]*if *\(\w+ *! It only nearly worked. ^[ \t]* is wrong, since it matches one or none [space or tab]. What I want is to match anything that may contain only space or tab (or nothing). For example these should not match: // if (asdf != 0) else if (asdf != 1) How can I modify my regexp for that?

  • Android - Connectivity Questions

    - by Donal Rafferty
    I have a couple of questions about connectivity on Android, if anyone has any insight it would be great. What is the default when an application wants to wirelessly connect? Is it wlan? And if wlan is switched off or there is no access points around is it 3g or gprs? Is a device always ip connected? Or when its disabled from wlan or 3g does it lose its ip address? Is an application, for example the browser only ever connected to one ip address? Or can it be connected to multiple addresses for each radio such as gprs or wifi (wlan)? Can an application decide which connection to open a socket to? For example can I create an application and decide whether to connect the socket to the wlan or gprs? Or does the OS decide? Finally how do native applications handle connectivity? In the same manner?

  • Handling exception form unmanaged dll in C#

    Hello. I have the following function written in C# public static string GetNominativeDeclension(string surnameNamePatronimic) { if(surnameNamePatronimic == null) throw new ArgumentNullException("surnameNamePatronimic"); IntPtr[] ptrs = null; try { ptrs = StringsToIntPtrArray(surnameNamePatronimic); int resultLen = MaxResultBufSize; int err = decGetNominativePadeg(ptrs[0], ptrs[1], ref resultLen); ThrowException(err); return IntPtrToString(ptrs, resultLen); } catch { return surnameNamePatronimic; } finally { FreeIntPtr(ptrs); } } Function decGetNominativePadeg is in unmanaged dll [DllImport("Padeg.dll", EntryPoint = "GetNominativePadeg")] private static extern Int32 decGetNominativePadeg(IntPtr surnameNamePatronimic, IntPtr result, ref Int32 resultLength); and throws an exception: Attempted to read or write protected memory.

  • Simple Android OpenGL App Lag

    - by Eugene
    Hi, I have an Android OpenGL application which simply draws 2D squares (using 2 triangles) and animates them moving down the screen. I essentially do this by running: glLoadIdentity(), then glTranslatef, and finally glDrawElements all in a for loop. (The for loop is to draw all 10 blocks on the screen for every frame). In every drawFrame, the y-position of the blocks increments for the animation. The problem I'm having is strange. I run the application and the animation is laggy and not smooth. Then I re-run the application and I get a smooth animation. If I run again, I may get a smooth animation, or possibly not. Is my method correct, or is there a better way of doing this animation? Thanks for the help!

  • Need help understanding _set_security_error_handler()

    - by Emil D
    So , I've been reading this article: http://msdn.microsoft.com/en-us/library/aa290051%28VS.71%29.aspx And I would like to define my custom handler.However, I'm not sure I understand the mechanics well.What happens after a call is made to the user-defined function ( e.g. the argument of _set_security_error_handler() ) ? Does the program still terminate afterward ? If that is the case, is it possible to terminate only the current thread(assuming that it is not the main thread of the application).AFAIK, each thread has its own stack , so if the stack of a thread gets corrupted, the rest of the application shouldn't be affected. Finally, if it is indeed possible to only terminate the current thread of execution, what potential problems could such an action cause? I'm trying to do all this inside an unmanaged C++ dll that I would like to use in my C# code.

  • Hadoop on Amazon EC2 : Job tracker not starting properly

    - by Algorist
    Hi, We are running Hadoop on Amazon EC2 cluster. We start the master, slaves and attach the ebs volumes and finally waiting for hadoop jobtracker, tasktracker etc to start and we have timeout of 3600 seconds. We are noticing 50% of the time that job tracker is not able to start before the timeout. Reason being, hdfs is not initialized properly and still in safemode and job tracker is unable to start. I noticed few connectivity issues between nodes on EC2 as I tried manually pinging slaves. Did anyone face similar issue and know how to solve this? Thank you Bala

  • Jquery fade and swap an element when clicked which will also relate to an accordian menu

    - by Nik
    You will notice when you click posture 1 the description drops down and images appear on the right. Now when you click posture 2 or posture 3 the images and description change as they should. What I need to do now is - If posture 1 has been clicked and then posture 2 is clicked the posture 1 menu needs to close so that there is only one posture description visible at one time. If I could also make it so that if the current open posture item is clicked so that it closes and there are no open posture descriptions that there also no images displayed on the right. Finally is there a way to make sure only one set of animation images is running, because just say the user goes through all 26 options and they continue to run in the background it may get sluggish (thanks to Nick Craver for bringing that up). At this stage only posture 1, 2 and 3 are available. Ok finally some code - //Description drop-down boxes $(document).ready(function(){ //Hide (Collapse) the toggle containers on load $(".toggle_container").hide(); //Switch the "Open" and "Close" state per click $("h5.trigger").toggle(function(){ $(this).addClass("active"); }, function () { $(this).removeClass("active"); }); //Slide up and down on click $("h5.trigger").click(function(){ $(this).next(".toggle_container").slideToggle("slow"); }); }); //Images on the right fade in and out thanks to aSeptik $(document).ready(function(){ $('#section_Q_01,#section_Q_02,#section_Q_03').hide(); $(function() { $('h5.trigger a').click( function(e) { e.preventDefault(); var trigger_id = $(this).parent().attr('id'); //get id Q_## $('.current').removeClass('current').hide(); //add a class for easy access & hide $('#section_' + trigger_id).addClass('current').fadeIn(5000); //show clicked one }); }); }); //Fading pics $(document).ready(function(){ $('.pics').cycle({ fx: 'fade', speed: 2500 }); }); Description boxes - <h5 class="trigger" id="Q_01" ><a href="#">Posture 1 : Standing Deep Breathing :</a></h5> <div class="toggle_container" > <div class="block"> <span class="sc">Pranayama Series</span> <p class="bold">Benefits:</p> </div> </div> <h5 class="trigger" id="Q_02" ><a href="#">Posture 2 : Half Moon Pose With Hands To Feet Pose :</a></h5> <div class="toggle_container"> <div class="block"> <span class="sc">Ardha Chandrasana with Pada-Hastasana</span> <p class="bold">Benefits:</p> </div> </div> <h5 class="trigger" id="Q_03" ><a href="#">Posture 3 : Awkward Pose :</a></h5> <div class="toggle_container"> <div class="block"> <span class="sc">Utkatasana</span> <p class="bold">Benefits:</p> </div> </div> and the images on the right - <div id="section_Q_01" class="01"> <div class="pics"> <img src="../images/multi/poses/pose1/Pranayama._01.jpg"/> <img src="../images/multi/poses/pose1/Pranayama._02.jpg"/> <img src="../images/multi/poses/pose1/Pranayama._03.jpg"/> </div> </div> <div id="section_Q_02" class="02"> <div class="pics"> <img src="../images/multi/poses/pose2/Half_Moon_Pose_04.jpg" /> <img src="../images/multi/poses/pose2/Backward_Bending_05.jpg" /> <img src="../images/multi/poses/pose2/Hands_to_Feet_Pose_06.jpg" /> </div> </div> <div id="section_Q_03" class="03"> <div class="pics"> <img src="../images/multi/poses/pose3/Awkward_01.jpg" /> <img src="../images/multi/poses/pose3/Awkward_02.jpg" /> <img src="../images/multi/poses/pose3/Awkward_03.jpg" /> </div> </div> It would be a bonus if images faded out when another element is clicked... but not a big deal.
