  • OpenGL Motion blur with the accumulation buffer in WxWidgets

    - by Klaus
    Hello, I'm trying to achieve a motion blur effect in my OpenGL application. I read somewhere this solution, using the accumulation buffer: glAccum(GL_MULT, 0.90); glAccum(GL_ACCUM, 0.10); glAccum(GL_RETURN, 1.0); glFlush(); at the end of the render loop. But nothing happens... What am I missing ? Additions after genpfault answer: Indeed I did not asked for an accumulation buffer when I initialized my context. So I tried to pass an array of attributes to the constructor of my wxGLCanvas, as described here: http://docs.wxwidgets.org/2.6/wx_wxglcanvas.html : int attribList[]={ WX_GL_RGBA , WX_GL_DOUBLEBUFFER , WX_GL_MIN_ACCUM_RED, WX_GL_MIN_ACCUM_GREEN, WX_GL_MIN_ACCUM_BLUE, 0} But all I get is a friendly Seg fault. Does someone understand how to use this ? (no problems with int attribList[]={ WX_GL_RGBA , WX_GL_DOUBLEBUFFER , 0})

  • Variable-byte encoding clarification

    - by Myx
    Hello: I am very new to the world of byte encoding so please excuse me (and by all means, correct me) if I am using/expressing simple concepts in the wrong way. I am trying to understand variable-byte encoding. I have read the Wikipedia article (http://en.wikipedia.org/wiki/Variable-width_encoding) as well as a book chapter from an Information Retrieval textbook. I think I understand how to encode a decimal integer. For example, if I wanted to provide variable-byte encoding for the integer 60, I would have the following result: 1 0 1 1 1 1 0 0 (please let me know if the above is incorrect). If I understand the scheme, then I'm not completely sure how the information is compressed. Is it because usually we would use 32 bits to represent an integer, so that representing 60 would result in 1 1 1 1 0 0 preceded by 26 zeros, thus wasting that space as opposed to representing it with just 8 bits instead? Thank you in advance for the clarifications.

  • How to create named pipe (mkfifo) in Android?

    - by Ignas Limanauskas
    I am having trouble in creating named pipe in Android and the example below illustrates my dilemma: res = mkfifo("/sdcard/fifo9000", S_IRWXO); if (res != 0) { LOG("Error while creating a pipe (return:%d, errno:%d)", res, errno); } The code always prints: Error while creating a pipe (return:-1, errno:1) I can't figure out exactly why this fails. The application has android.permission.WRITE_EXTERNAL_STORAGE permissions. I can create normal files with exactly the same name in the same location, but pipe creation fails. The pipe in question should be accessible from multiple applications. I suspect that noone can create pipes in /sdcard. Where would it be the best location to do so? What mode mast should I set (2nd parameter)? Does application need any extra permissions?

  • using Swing components in javafx if they're not in the NetBeans javafx palette

    - by Jason S
    I'm just getting started with javafx in NetBeans, and I have it doing simple stuff (windows with buttons + the like) but would like to try something slightly more realistic. The "Swing/AWT Components" palette has a whole bunch of stuff that the "JavaFX Script Code Clips" palette does not (it has Button, CheckBox, ComboBox, ComboBoxItem, Label, RadioButton, Slider, TextField, and ToggleButton). How do I add stuff to this palette? I would like to try using some of the components in org-netbeans-swing-outline.jar edit: Aha. I was missing the point somewhat: there are only some javafx-wrapped Swing components available in javafx.ext.Swing.*, so if you want one of the other Swing components you have to wrap them yourself.

  • visual studio 2010 database project, is there a visual way?

    - by b0x0rz
    started a visual studio 2010 database project. however i am only able to write sql in a text mode, there is no functionality in making the table for example in a visual view as exists when you add a new database to app_data folder and the work on it there. is this the only way and there is no visual way of doing this in the visual studio 2010 database project? or am i missing some obvious way of getting to it? thank you also if there is a tutorial anywhere (video maybe!?) please link it. i only found importing a database from an existing script video using a wizard. would like new database from scratch without wizard.

  • LaTeX at symbol

    - by secondbanana
    What does the @ symbol mean in LaTeX? I'm looking at the source of apa.cls, and there's a declaration: \newsavebox\gr@box and later on \sbox\gr@box{\includegraphics[width=\linewidth]{#2}}. It seems like @ isn't acting as a normal character, but I can't figure out exactly what it's doing, and couldn't find anything after bit of googling (how I would love a Google regex feature!) Thanks. EDIT: Thanks for the help; of the links I looked through I found http://www.tug.org/pipermail/tugindia/2002-January/000178.html to be very helpful and concise. To summarize, the @ character is not normally allowed in the names of macros, so as a hack for scoping, LaTeX packages declare it internally to be a valid name character and use it for their macros. You can use \makeatletter in a document to access these macros, but you obviously must be very careful since you have can now overwrite essential LaTeX kernel macros; use \makeatother to revert.

  • Good code highlighting, syntax analysis and code assist editor on js.erb and css.erb files

    - by Pickachu
    I want to know if there is a good compatible api that supports erb and javascript highlighting. I've already tried Eclipse with Aptana RadRails. Perhaps I'm configuring something wrong, but it guesses that I'm using html.erb on both css.erb and js.erb files. I've tried too the Emacs with js2-mode, nXhtml and Rinari modes. Again, it works fine for html.erb, but it detects the css.erb and js.erb as html.erb files. Maybe it's possible to configure it to accept that files and be compatible.

  • Using DLL that using COM in C#

    - by chekalin-v
    I have been writing DLL on C++, that will be use in C#. DLL have some function, where I call hres = CoInitializeEx(NULL, COINIT_MULTITHREADED); and next call hres = CoInitializeSecurity( NULL, -1, // COM authentication NULL, // Authentication services NULL, // Reserved RPC_C_AUTHN_LEVEL_PKT, // Default authentication RPC_C_IMP_LEVEL_IMPERSONATE, // Default Impersonation NULL, // Authentication info EOAC_NONE, // Additional capabilities NULL // Reserved ); There are no error then I trying to use this dll in C++. But if I call function from DLL via C# application I see Error (80010106) Cannot change thread mode after it is set. I changed hres = CoInitializeEx(NULL, COINIT_MULTITHREADED); to hres = CoInitialize(NULL); After this changes error appear after CoInitializeSecurity: (80010119) Security must be initialized before any interfaces are marshalled or unmarshalled. It cannot be changed once initialized. How resolve this trouble?

  • Hidden features of x86 assembly

    - by Earlz
    I am still a fan of x86 assembly(sorta) and know a lot of developers still using x86 assembly, although by far there are very few features available in assembly, let us list out the most useful and not so well known ones. Of course the question is on the lines of the Hidden Features questions listed below.: Hidden Features of JavaScript Hidden Features of CSS Hidden Features of C# Hidden Features of VB.NET Hidden Features of Java Hidden Features of ASP.NET Hidden Features of Python Hidden Features of TextPad Hidden Features of Eclipse Hidden Features of Classic ASP Please specify one feature per answer. Also, you can specify all bits of the x86 such as 16bit(real mode), 32bit, and 64bit. Please keep it neutral of assembler though. Both Intel and AT&T syntax is welcome but please don't for example demonstrate a useful macro feature for yasm.

  • Visual studio won't debug into referenced DLL (from same solution)

    - by Greg
    I have a Visual studio 2008 solution, with 2 projects. A DLL, A, and a Web application, B. B has a project reference to A, and A.dll and A.pdb are being copied to B's bin/ directory. Everything is set to compile in debug mode. I can run the cassini webserver and debug web application B fine, but when I come to call a method in A.dll, pressing F11 to step into it does not step into it, it steps over it. I want to step into it. Any ideas why I might not be able to step into the source code of A?

  • How to retain service settings through InstallShield upgrade install

    - by sjohnston
    I have an InstallScript project in IS2010. It has a handful of services that get installed. Some are C++ exes and use the "InstallShield Object for NT Services". Others are Java apps installed as services with Java Service Wrapper through LaunchAppAndWait command line calls. Tomcat is also being installed as a service through a call to its service.bat. When the installer runs in upgrade mode, the services are reinstalled, and the settings (auto vs. manual startup, restart on fail, log-on account, etc.) are reverted to the defaults. I would like to save the service settings before the file transfer and then repopulate them afterward, but I haven't been able to find a good mechanism to do this. How can I save and restore the service settings?

  • C# - Determine if class initializaion causes infinite recursion?

    - by John M
    I am working on porting a VB6 application to C# (Winforms 3.5) and while doing so I'm trying to break up the functionality into various classes (ie database class, data validation class, string manipulation class). Right now when I attempt to run the program in Debug mode the program pauses and then crashes with a StackOverFlowException. VS 2008 suggests a infinite recursion cause. I have been trying to trace what might be causing this recursion and right now my only hypothesis is that class initializations (which I do in the header(?) of each class). My thought is this: mainForm initializes classA classA initializes classB classB initializes classA .... Does this make sense or should I be looking elsewhere? UPDATE1 (a code sample): mainForm namespace john { public partial class frmLogin : Form { stringCustom sc = new sc(); stringCustom namespace john { class stringCustom { retrieveValues rv = new retrieveValues(); retrieveValues namespace john { class retrieveValues { stringCustom sc = new stringCustom();

  • Python TKinter connect variable to entry widget

    - by Sano98
    Hi everyone, I'm trying to associate a variable with a Tkinter entry widget, in a way that: Whenever I change the value (the "content") of the entry, mainly by typing something into it, the variable automatically gets assigned the value of what I've typed. Without me having to push a button "Update value " or something like that first. Whenever the variable gets changed (by some other part of the programm), I want the entry value displayed to be adjusted automatically. I believe that this could work via the textvariable. I read the example on http://effbot.org/tkinterbook/entry.htm, but it is not exactly helping me for what I have in mind. I have a feeling that there is a way of ensuring the first condition with using entry's "validate". Any ideas? Thank you for your input! Sano

    I want to define access for some pages for user who has one of following roles (ROLE1 or ROLE2) I'm trying to configure this in my spring security xml file as following: <security:http entry-point-ref="restAuthenticationEntryPoint" access-decision-manager-ref="accessDecisionManager" xmlns="http://www.springframework.org/schema/security" use-expressions="true"> <!-- skipped configuration --> <security:intercept-url pattern="/rest/api/myUrl*" access="hasRole('ROLE1') or hasRole('ROLE2')" /> <!-- skipped configuration --> </security:http> I've tried various ways like: access="hasRole('ROLE1, ROLE2')" access="hasRole('ROLE1', 'ROLE2')" access="hasAnyRole('[ROLE1', 'ROLE2]')" etc but nothing seems to be working. I'm keep getting exception java.lang.IllegalArgumentException: Unsupported configuration attributes: or java.lang.IllegalArgumentException: Failed to parse expression 'hasAnyRole(['ROLE1', 'ROLE2'])' how should it be configured?

  • sqlserver 2008 and sql CE over Microsoft sync framework

    - by malik
    The server will drop the connection, because the client driver has sent multiple requests while the session is in single-user mode. This error occurs when a client sends a request to reset the connection while there are batches still running in the session, or when the client sends a request while the session is resetting a connection. Please contact the client driver vendor. Synchronisation process some time work and mostly fails. I have 5 client of sql CE that need to sync and i am using WCF IIS and sql 2008 for this process.

  • Nhibernate Criteria Ignore Child Collection

    - by CocoB
    I have a simple one to many association in my model. The parent class has a collection of children. In the mapping files, the association is a one to many, eager-loaded, using fetchmode.join. This works fine, but how can I write a criteria query but NOT trigger the loading of the child collection? In other words, I want to query the parent and not have it generate the join in the resulting sql. I tried setting the fetch mode to lazy, but in that case Nhibernate generates two separate queries. I don't want the table for child queried at all.

  • Internet Explorer shows error when downloading excel file in SSL site

    - by Billy
    I get the following error when downloading excel file in SSL site: Internet Explorer cannot download xxxx.aspx from mysite.com. Internet Explorer was not able to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later. After googling, I suspect that it's the problem of the response header. I try the solution in this page and set the header: http://trac.edgewall.org/ticket/1020 HttpContext.Current.Response.AddHeader("Pragma", "no-cache"); HttpContext.Current.Response.CacheControl = "private"; But it doesn't work. Any suggestions?

  • Visual Studio 2008/2010 & SQL Server 2008 on Windows 7 Home Premium

    - by Steve
    Are there any limitations with respect to developing ASP.NET and WPF apps using VS 2008/2010 and SQL Server 2008 on Windows 7 Home Premium? I know you can run IIS 7.5 on Home Premium. I Googled and Binged on Home Premium and VS/SQL Server and couldn't find much. It doesn't look like the features missing from Home Premium, domain joining, xp mode, etc... shouldn't prevent one from running and developing in VS/SQL Server. Update I did discover one limitation w/IIS 7.5 and it applies to all versions of Windows 7 I think. You can't create your own self signed SSL certificate specifying a name other than the machine name. You're stuck with your machine name which isn't that big a deal, but it is a change from previous versions.

  • Level of SVG SMIL (animation) support among the browsers

    - by user246114
    Hi, Does anyone know the current state of SVG SMIL animation support in the popular browsers? It looks like Safari, Chrome, and Opera support it. Firefox has confusing reports in their dev pages about SMIL support having been added, but I don't see it as of v3.6: https://bugzilla.mozilla.org/show_bug.cgi?id=216462 I am ignoring IE since they don't even support SVG at all, and probably never will, much less SMIL. The other thing - just comparing this test page between Safari, Chrome, and Opera: http://srufaculty.sru.edu/david.dailey/svg/ovaling.svg looks like Opera is the only one that renders it correctly. Should we not be using SMIL - kind of looks half-baked in all the browsers (sadly)? Blast. Thanks

  • How does Facebook chat avoid continuous polling of the server?

    - by Chad Johnson
    I am trying to understand how Facebook's chat feature receives messages without continuously poling the server. Firebug shows me a single GET XmlHttpRequest continuously sitting there, waiting for a response from the server. After 5 minutes, this never timed out. How are they preventing timeout? An AJAX request can just sit there like that indefinitely, waiting for a response? Can I do this with JSONRequest? I see this at json.org: JSONRequest is designed to support duplex connections. This permits applications in which the server can asynchronously initiate transmissions. This is done by using two simultaneous requests: one to send and the other to receive. By using the timeout parameter, a POST request can be left pending until the server determines that it has timely data to send. Or is there another way to let an AJAX call just sit there, waiting, besides using JSONRequest?
