• Getting lpfnAcceptEx (accpetex) to block in native C++

  - by Alikar

  Hello, I've been trying to get the lpfnAcceptEX function in Win32 to block on accept. If this is not possible I was wondering if there was a flag I could accpet or some other function that I could wait on. Right now the program is simply continually creating accepted sockets with no connections behind them. Perhaps I am misunderstanding how this is to work. Is there another function I need to wait on? I am following the example laid out here: http://msdn.microsoft.com/en-us/library/ms737524(VS.85).aspx Thanks, = Alikar

• Taxonomy terms are not translated in an exposed filters block

  - by Daj pan spokój

  Hi, in my view's exposed filters block the taxonomy terms are showed only in the original language version (in English). Vocabulary is set to Localize terms. The terms are translated via Translation Table. All the other content (Views, nodes, translated strings etc.) is showed correctly (in German). I'd expect them to appear in current language, however. Here for instance, I'd expect to have German Sommer 10 instead of English Summer 10. Do You have any idea how to solve it? I use Drupal 6 and Views 2.10

• Java concurrency - Should block or yield?

  - by teto

  Hi, I have multiple threads each one with its own private concurrent queue and all they do is run an infinite loop retrieving messages from it. It could happen that one of the queues doesn't receive messages for a period of time (maybe a couple seconds), and also they could come in big bursts and fast processing is necessary. I would like to know what would be the most appropriate to do in the first case: use a blocking queue and block the thread until I have more input or do a Thread.yield()? I want to have as much CPU resources available as possible at a given time, as the number of concurrent threads may increase with time, but also I don't want the message processing to fall behind, as there is no guarantee of when the thread will be reescheduled for execution when doing a yield(). I know that hardware, operating system and other factors play an important role here, but setting that aside and looking at it from a Java (JVM?) point of view, what would be the most optimal?

• Call function by pointer and set parametrs in memory block

  - by Ellesmess Glain

  Hi, I've little problem : I'm solving problem with calling function by pointer and passing to it parameters in continuous memory block. My goal is to have function named e.g CallFunc(void * func,void *params, unsigned int param_length); that I'll send function pointer, pointer to function's parameters and eventually parameters length and this calling function will call passed function with it's parameters. I will like write this in C/C++, but if somebody has idea, how this resolve in other language, that supports DLL generation and exportet functions, it will be fine too. Thanks for answers, Ellesmess P.S. I'm sorry about my English, but I'm Czech, thanks :o)

• try except block in Delphi

  - by Nik

  Do you guys know a way to trap log and re-raise exception in Delphi code. A simple example: procedure TForm3.Button1Click(Sender: TObject); begin try raise Exception.Create('Bum'); except on E: Exception do begin MyHandleException(E); end; end; end; procedure TForm3.MyHandleException(AException: Exception); begin ShowMessage(AException.Message); // raise AException; - this will access violate end; So I need to re-raise it in the except block but I was wondering is there a better way to write my own method to handle and (on specific conditions) to re-raise exceptions?

• UPDATE statement wrapped in an IF EXISTS block

  - by formica

  I'm trying to write a DML script that updates a column but I wanted to make sure the column existed first so I wrapped it in a IF EXISTS block IF EXISTS(SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME='Client' AND COLUMN_NAME='IsClarityEnabled') BEGIN UPDATE Client SET IsClarityEnabled = 1 WHERE ClientID = 21 END So the weirdness is that it tries to execute the update even if it fails the condition. So column doesn't exist and the UPDATE statement runs and I get an error. Why? Even stranger is that this does work: IF EXISTS(SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME='Client' AND COLUMN_NAME='IsClarityEnabled') BEGIN EXEC('UPDATE Client SET IsClarityEnabled = 1 WHERE ClientID = 21') END Is there something special about an UPDATE command that causes it to behave this way?

• Removing a text block from a file : sed ?

  - by user555338

  Hi, Following an attack, I need to remove 4 lines of text added to .htaccess files in my site, and was thinking SED would be the way to go, but cannot see how in spire of many attempts. The added lines are RewriteEngine On RewriteCond %{HTTP_REFERER} ^http:// RewriteCond %{HTTP_REFERER} !%{HTTP_HOST} RewriteRule . http://targeturlhere.net/%{REMOTE_ADDR} I managed to create the script to remove added htaccess files containing those lines only, but for existing htaccess files in which that was appended I have to edit the file and cannot delete it. I cannot just remove line by line nor use "RewriteEngine On" as the start marker, as this instruction "RewriteEngine On" is sometimes legitimate elsewhere in the file. In most cases those lines are the last, but I guess in other files they could be in the middle, so I was trying to remove exactly that block - and have a script I could reuse in a similar case. (Edit: my 4 lines are below one another, no blank line in between but the editor here seems to either show no breakline, or one adding a blank line) Any hint or tip ? Thanks.

• try finally block around every Object.Create?

  - by max

  Hi, I have a general question about best practice in OO Delphi. Currently, I but a try finally block around everywhere, where I create an object, to free that object after usage (to avoid memory leaks). E.g.: aObject := TObject.Create; try aOBject.AProcedure(); ... finally aObject.Free; end; instead of: aObject := TObject.Create; aObject.AProcedure(); .. aObject.Free; To you think, it is good practice, or too much overhead? And what about the performance?

• JQuery animate behaviour with inline-block elements

  - by IlludiumPu36

  I'm using JQuery to animate two divs, one on top of the other, inside a another div. The effect is like a button with the top and bottom halves opening up and down to reveal some contents. The idea is to have a number of these 'buttons' in line using float:left When a button is clicked, the script checks if another button is open, if so, closes that button and opens the clicked button. This works fine, except I want to change float:left to display:inline-block on the container div class (to prevent wrapping of a number of buttons if the browser is resized). The problem is the layout of buttons breaks as JQuery animate seems to be changing the vertical position of the button containers while animating. See fiddle

• What will or won't cause a thread to block (a question from a test)

  - by fingerprint211b

  I've had a test, and there was a question I lost some points on, because I wasn't able to answer it : Which of the following is NOT a condition which can cause a thread to block : Calling an objects's wait() method Waiting for an I/O operation Calling sleep() Calling yield() Calling join() As far as I know, all of these are blocking calls : wait() returns when an something calls notify(), blocks until then If the thread is WAITING for an I/O operation then it's obviously blocked sleep(), obviously, blocks until the time runs out, or something wakes up the thread yield() "cancels the rest of the thread's timeslice" (lacking a better term), and returns only when the thread is active again join() blocks until the thread it's waiting for terminates. Am I missing something here?

• Switched from DVI to HDMI, possible audio artifacts?

  - by I take Drukqs

  I'm using an ASUS VH236H monitor and an EVGA GeForce 570 GTX both of which are brand new. My monitor has an audio out port for speakers/headphones so I plugged in my headphones and made a random selection from my library when I noticed two things: There are static-like artifacts during "louder" parts of songs. There's what seems to be a volume cap in place. When I crank the volume past 100% in VLC the decibel level does not truly increase but the amount of static does. The cable is not new; I yanked it off of my PS3 when my DVI cable broke. It has been used a good amount on my HDTV and PS3 so I doubt it's a matter of burn-in. I like the way the setup works with an HDMI cable as opposed to DVI because my headphones barely reach my rig whereas I have plenty of slack when they're plugged into my monitor. Thanks in advance for any support. Note: I'm using a high quality HDMI cable from monoprice, AKG K702 headphones, and VLC media player.

• Nginx: Disallow index.html in URL

  - by Martin Vilcans

  We're generating a site consisting of only static files (using Assemble). Having the .html extension on URLs looks so nineties, so we generate every static HTML file in its own directory and call it index.html. For example, the url http://www.example.com/foo/bar/ is in the file /var/www/foo/bar/index.html. This works well, but there is one small thing nagging me: Now there are two possible URLs to the same resource: http://www.example.com/foo/bar/ (slash URL) http://www.example.com/foo/bar/index.html (index.html URL) By accident someone may link to the index.html form of the URL, which is bad for SEO and looks ugly (remember the nineties?). Is it possible in Nginx to give a 404 error on the index.html URL, but serve the slash URL? I tried this: location ~ /index\.html$ { return 404; } But it seems that Nginx does some internal rewrite of the slash URL to the index.html URL, and then matches this location so we get a 404 even on the slash URL. Note that to catch mistakes, we want index.html URLs to be an error, not just redirect to the slash URL.

• Templates, interfaces (multiple inheritance) and static functions (named constructors)

  - by fledgling Cxx user

  Setup I have a graph library where I am trying to decompose things as much as possible, and the cleanest way to describe it that I found is the following: there is a vanilla type node implementing only a list of edges: class node { public: int* edges; int edge_count; }; Then, I would like to be able to add interfaces to this whole mix, like so: template <class T> class node_weight { public: T weight; }; template <class T> class node_position { public: T x; T y; }; and so on. Then, the actual graph class comes in, which is templated on the actual type of node: template <class node_T> class graph { protected: node_T* nodes; public: static graph cartesian(int n, int m) { graph r; r.nodes = new node_T[n * m]; return r; } }; The twist is that it has named constructors which construct some special graphs, like a Cartesian lattice. In this case, I would like to be able to add some extra information into the graph, depending on what interfaces are implemented by node_T. What would be the best way to accomplish this? Possible solution I thought of the following humble solution, through dynamic_cast<>: template <class node_T, class weight_T, class position_T> class graph { protected: node_T* nodes; public: static graph cartesian(int n, int m) { graph r; r.nodes = new node_T[n * m]; if (dynamic_cast<node_weight<weight_T>>(r.nodes[0]) != nullptr) { // do stuff knowing you can add weights } if (dynamic_cast<node_position<positionT>>(r.nodes[0]) != nullptr) { // do stuff knowing you can set position } return r; } }; which would operate on node_T being the following: template <class weight_T, class position_T> class node_weight_position : public node, public node_weight<weight_T>, public node_position<position_T> { // ... }; Questions Is this -- philosophically -- the right way to go? I know people don't look nicely at multiple inheritance, though with "interfaces" like these it should all be fine. There are unfortunately problems with this. From what I know at least, dynamic_cast<> involves quite a bit of run-time overhead. Hence, I run into a problem with what I had solved earlier: writing graph algorithms that require weights independently of whether the actual node_T class has weights or not. The solution with this 'interface' approach would be to write a function: template <class node_T, class weight_T> inline weight_T get_weight(node_T const & n) { if (dynamic_cast<node_weight<weight_T>>(n) != nullptr) { return dynamic_cast<node_weight<weight_T>>(n).weight; } return T(1); } but the issue with it is that it works using run-time information (dynamic_cast), yet in principle I would like to decide it at compile-time and thus make the code more efficient. If there is a different solution that would solve both problems, especially a cleaner and better one than what I have, I would love to hear about it!

Is there a simple way to disable all logging for now? Removing the logging is problematic as it's used in the underlying libraries. I have tried setting all switchValue="All" to "Off" but it still throws the exception even though nothing should be logged

• How do I generate a level randomly?

  - by Charlton Santana

  I am currently hard coding 10 different instances like the code below, but but I'd like to create many more. Instead of having the same layout for the new level, I was wondering if there is anyway to generate a random X value for each block (this will be how far into the level it is). A level 100,000 pixels wide would be good enough but if anyone knows a system to make the level go on and on, I'd like to know that too. This is basically how I define a block now (with irrelevant code removed): block = new Block(R.drawable.block, 400, platformheight); block2 = new Block(R.drawable.block, 600, platformheight); block3 = new Block(R.drawable.block, 750, platformheight); The 400 is the X position, which I'd like to place randomly through the level, the platformheight variable defines the Y position which I don't want to change.

• Serving static content with jetty 7, using defaultservlet configured from web.xml

  - by Chilly

  Hi All, This is jetty 7 and xml configured, not embedded. I'm trying to serve a static file, crossdomain.xml, to an app that connects to a datasource I run from jetty. To do this, I configured a servlet and its mapping thus: default org.eclipse.jetty.servlet.DefaultServlet resourceBase /moo/somedirectory default /* Sadly all I get are 404's. Any help would be much appreciated, btw the rest of my web.xm lfile looks like: <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5" cometd org.cometd.server.continuation.ContinuationCometdServlet 1 cometd /cometd/* default org.eclipse.jetty.servlet.DefaultServlet resourceBase /foo/foo default /* initializer com.foo.research.Initializer 2 cross-origin org.eclipse.jetty.servlets.CrossOriginFilter cross-origin /cometd/* </web-app>

• Packaging a Bundle with a static library

  - by 4thSpace

  I have a static library that includes some xibs. These will basically be the same across projects. I'd like to include the xibs as part of the library. I can include their veiwcontrollers, reference these controllers in the calling project but then there isn't a xib to load. When I right click the xib in the library project, it can't be part of the target. I thought about creating a CFPluginBundle but that creates a new project. I'd loose all of my IBOutlet and IBAction references. What is the best way to reuse xibs that also have outlets and actions to specific controllers?

• classes and static variables in shared libraries

  - by abel

  I am trying to write something in c++ with an architecture like: App -- Core (.so) <-- Plugins (.so's) for linux, mac and windows. The Core is implicitly linked to App and Plugins are explicitly linked with dlopen/LoadLibrary to App. The problem I have: static variables in Core are duplicated at run-time -- Plugins and App have different copys of them. at least on mac, when a Plugin returns a pointer to App, dynamic casting that pointer in App always result in NULL. Can anyone give me some explanations and instructions for different platforms please? I know this may seem lazy to ask them all here but I really cannot find a systematic answer to this question.

• Static web project in Visual Web Developer Express

I want to have all the niceties with intellisense, sulution explorer and whatnot but I don't want all of the ASP.net structure in the sulution. Is thiss possible or is there perhaps another IDE for this kind of project? Thanks!

• using Java enums or public static fields in MATLAB

  - by Jason S

  I'm wondering how in MATLAB you can get a reference to a Java enum or static public field. In MATLAB, if you are trying to use Java objects/methods, there are equivalents to Java object creation / method call / etc.: Java: new com.example.test.Foo(); MATLAB: javaObject('com.example.test.Foo'); Java: com.example.test.Foo.staticMethod(); MATLAB: javaMethod('staticMethod', 'com.example.test.Foo'); Java: SomeEnum e = com.example.test.SomeEnum.MY_FAVORITE_ENUM; MATLAB: ????? Java: int n = com.example.test.Foo.MAX_FOO; MATLAB: ?????

• django authentication .htaccess static

  - by Uszy Wieloryba

  In my app users can upload files for other users. To make the uploaded files accesible only for the addresse I need some kind of static files authentication system. My idea, is to create the apache hosted directory for each user and to limit access to this derectory using .htaccess. This means that each time new django user is created, I need to create a directory and the appropriate .htaccess file in it. I know I should do it using post_save signals on User model but I don't know how to create the .htaccess in the user's directory from python level. Can you help me with that? Or perhaps you have better solution to my problem?

• pthread_create from non-static member function

  - by Stanislav Palatnik

  This is somewhat similiar to this : http://stackoverflow.com/questions/1151582/pthread-function-from-a-class But the function that's getting called in the end is referencing the this pointer, so it cannot be made static. void * Server::processRequest() { std::string tmp_request, outRequest; tmp_request = this->readData(); outRequest = this->parse(tmp_request); this->writeReply(outRequest); } void * LaunchMemberFunction(void * obj) { return ((Server *)obj)->processRequest(); } and then the pthread_create pthread_create(&handler[tcount], &attr, (void*)LaunchMemberFunction,(void*)&SServer); errors: SS_Twitter.cpp:819: error: invalid conversion from void* to void* ()(void) SS_Twitter.cpp:819: error: initializing argument 3 of int pthread_create(pthread_t*, const pthread_attr_t*, void* ()(void), void*)

• Include static file in JSP with variable filename on WebSphere 6

  - by cringe

  I'm struggling with including a static file into my JSPs on Websphere 6.0.2.17. I tried this: <% final String MY_DIR = ResourceBundle.getBundle("mybundle").getString("props.pages.wcm"); %> <% final String page = ResourceBundle.getBundle("mybundle").getString("page"); %> <% final String inc = MY_DIR + "/" + bonus; %> <%@include file="<%= inc %>"%> The path is /wcm/some/other/dir/page and I can happily print that out with out.write(inc). Unfortunatly the include (and the jsp:include) isn't including the file at all. There is no error message, but the content isn't included... The file is accessible via the browser though. Do I have to create a full JSP for this to work? I just need a HTML file.
