• Tableview lags, and glitches while scrolling due to images loading in each cell

  - by Luis Tovar

  Hey Guys! Me again! Can someone provide me with some example code of how to properly load images in a tablecell without making the tableview glitch while scrolling. For example if you look at fandago's app, when scrolling through their movies you can see that the image is loaded asynchronously so that the scroll isnt jumping, lagging, or glitchy. Thanks in advance. Right now I have the images loading just fine but it is glitchy as i scroll because the images are loading on main thread. I am creating an app very similar to fandango. PS I am downloading these images via xml. (you know what i mean) Thanks!!

• C# Login Dialog Implementation

  - by arc1880

  I have implemented a LoginAccess class that prompts the user to enter their active directory username and password. Then I save the login data as an encrypted file. Every subsequent start of the application, the LoginAccess class will read the encrypted file and check against the active directory to see if the login information is still valid. If it is not, then it will prompt the user again. I have made it so that the reading of the encrypted file and displaying of the login dialog is done on a separate thread. A delegate is fired when the login process is complete. The issue that I'm having is that I have a class that is used in multiple places. This class contains the call to the LoginAccess object. Every time I instantiate a new object there are multiple calls to the LoginAccess object and I get multiple dialogs appearing when it tries to prompt for a username and password. Any suggestions on how to have only one dialog appear would be greatly appreciated.

• Bloomberg APIv3 returning Slow Consumer Warnings!

  - by Marcus

  I made a program in c# based on the example "SubscriptionWithEventHandlerExample" of API 3.2.9.0. After subscribing to about 500 securities for realtime data, I receive some ADMIN event warnings claiming SlowConsumerWarning and SlowConsumerWarningCleared. I read somewhere that it introduces some delay, until I process all events. The problem is that in my code I only receive callbacks from bloomberg. The event queue isn´t even in my program! Some things that I tried: 1) raise the queue limit, setting MaxEventQueueSize in the session options (seems to have no effect) 2) see if I get any timeout event (no, I don't get any) 3) create multiple sessions and subscribing 50 securities in each (now I get multiple warnings, one for each thread) Is there something that I can do or this behavior is out of my scope?

• Unable to forward UITouch events to my view controller

  - by hyn

  I have a UISplitViewController setup with a custom view added as a subview of the view (UILayoutContainerView) of split view controller. I am trying to forward touch events from my custom view controller to the master and detail views, but the following (which was suggested here on another thread) seems to have no effect: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; // Do something [self.nextResponder touchesBegan:touches withEvent:event]; } (I couldn't get this formatted properly) As a result my custom view controller locks the events and all the UI underneath never has a chance to do anything. How can I get my master and detail view controllers to receive events?

• Turn class "Interfaceable"

  - by scooterman

  Hi folks, On my company system, we use a class to represent beans. It is just a holder of information using boost::variant and some serialization/deserialization stuff. It works well, but we have a problem: it is not over an interface, and since we use modularization through dlls, building an interface for it is getting very complicated, since it is used in almost every part of our app, and sadly interfaces (abstract classes ) on c++ have to be accessed through pointers, witch makes almost impossible to refactor the entire system. Our structure is: dll A: interface definition through abstract class dll B: interface implementation there is a painless way to achieve that (maybe using templates, I don't know) or I should forget about making this work and simply link everything with dll B? thanks Edit: Here is my example. this is on dll A BeanProtocol is a holder of N dataprotocol itens, wich are acessed by a index. class DataProtocol; class UTILS_EXPORT BeanProtocol { public: virtual DataProtocol& get(const unsigned int ) const { throw std::runtime_error("Not implemented"); } virtual void getFields(std::list<unsigned int>&) const { throw std::runtime_error("Not implemented"); } virtual DataProtocol& operator[](const unsigned int ) { throw std::runtime_error("Not implemented"); } virtual DataProtocol& operator[](const unsigned int ) const { throw std::runtime_error("Not implemented"); } virtual void fromString(const std::string&) { throw std::runtime_error("Not implemented"); } virtual std::string toString() const { throw std::runtime_error("Not implemented"); } virtual void fromBinary(const std::string&) { throw std::runtime_error("Not implemented"); } virtual std::string toBinary() const { throw std::runtime_error("Not implemented"); } virtual BeanProtocol& operator=(const BeanProtocol&) { throw std::runtime_error("Not implemented"); } virtual bool operator==(const BeanProtocol&) const { throw std::runtime_error("Not implemented"); } virtual bool operator!=(const BeanProtocol&) const { throw std::runtime_error("Not implemented"); } virtual bool operator==(const char*) const { throw std::runtime_error("Not implemented"); } virtual bool hasKey(unsigned int field) const { throw std::runtime_error("Not implemented"); } }; the other class (named GenericBean) implements it. This is the only way I've found to make this work, but now I want to turn it in a truly interface and remove the UTILS_EXPORT (which is an _declspec macro), and finally remove the forced linkage of B with A.

• Help with SQL Join on two tables

  - by bladefist

  I have two tables, one is a table of forum threads. It has a last post date column. Another table has PostID, UserId, and DateViewed. I want to join these tables so I can compare DateViewed and LastPostDate for the current user. However, if they have never viewed the thread, there will not be a row in the 2nd table. This seems easy but I cant wrap my head around it. Advice please. Thanks in advance.

• Can't set default value of string property to "" in the Xcode CoreData model designer

  - by glenc

  I have an entity in my datamodel with a string property that is currently optional, and I'd like to convert this property to a required property with a default value of the empty string. As others have discovered, leaving the default value blank results in validation errors (since the designer interprets this as NULL), but trying '', "", or @"" as the default value results in those literal characters being interpreted as the default, rather than the empty zero-length string, as desired. I did find this thread on Google, however, apart from the solution being really ugly (model definition split between the .xcdatamodel and objc source), it also doesn't work for lightweight migrations because those migrations are done solely based on the .xcdatamodel files and the objc logic from your entity implementations isn't loaded. Is there any way to achieve this in the data model designer?

• Segmentation fault in std function std::_Rb_tree_rebalance_for_erase ()

  - by Sarah

  I'm somewhat new to programming and am unsure how to deal with a segmentation fault that appears to be coming from a std function. I hope I'm doing something stupid (i.e., misusing a container), because I have no idea how to fix it. The precise error is Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: KERN_INVALID_ADDRESS at address: 0x000000000000000c 0x00007fff8062b144 in std::_Rb_tree_rebalance_for_erase () (gdb) backtrace #0 0x00007fff8062b144 in std::_Rb_tree_rebalance_for_erase () #1 0x000000010000e593 in Simulation::runEpidSim (this=0x7fff5fbfcb20) at stl_tree.h:1263 #2 0x0000000100016078 in main () at main.cpp:43 The function that exits successfully just before the segmentation fault updates the contents of two containers. One is a boost::unordered_multimap called carriage; it contains one or more struct Infection objects that contain two doubles. The other container is of type std::multiset< Event, std::less< Event EventPQ called ce. It is full of Event structs. void Host::recover( int s, double recoverTime, EventPQ & ce ) { // Clearing all serotypes in carriage // and their associated recovery events in ce // and then updating susceptibility to each serotype double oldRecTime; int z; for ( InfectionMap::iterator itr = carriage.begin(); itr != carriage.end(); itr++ ) { z = itr->first; oldRecTime = (itr->second).recT; EventPQ::iterator epqItr = ce.find( Event(oldRecTime) ); assert( epqItr != ce.end() ); ce.erase( epqItr ); immune[ z ]++; } carriage.clear(); calcSusc(); // a function that edits an array cout << "Done with sync_recovery event." << endl; } The last cout << line appears immediately before the seg fault. I hope this is enough (but not too much) information. My idea so far is that the rebalancing is being attempting on ce after this function, but I am unsure why it would be failing. (It's unfortunately very hard for me to test this code by removing particular lines, since they would create logical inconsistencies and further problems, but if experienced programmers still think this is the way to go, I'll try.)

• Message pump in .NET Windows service

  - by Pickles

  I have a Windows Service written in C# that handles all of our external hardware I/O for a kiosk application. One of our new devices is a USB device that comes with an API in a native DLL. I have a proper P/Invoke wrapper class created. However, this API must be initialized with an HWnd to a windows application because it uses the message pump to raise asynchronous events. Besides putting in a request to the hardware manufacturer to provide us with an API that does not depend on a Windows message pump, is there any way to manually instantiate a message pump in a new thread in my Windows Service that I can pass into this API? Do I actually have to create a full Application class, or is there a lower level .NET class that encapsulates a message pump?

• How to check when animation finishes if animation block is

  - by pumpk1n

  I have a controller which adds as subviews a custom UIView class called Circle. Let's call a particular instance of Circle, "circle". I have a method in Circle, animateExpand, which expands the circle by animating the view. In the following code (which lives in the controller) I want to alloc and init a circle, add it to a NSMutableArray circleArray, animate the expansion, and at the end of the expansion, i want to remove the object from the array. My attempt: Circle *circle = [[Circle alloc] init]; [circleArray addObject:circle]; [circle animateExpand]; [circleArray removeObjectIdenticalTo:circle]; [circle release]; The problem is [circleArray removeObjectIdenticalTo:circle]; gets called before the animation finishes. Presumbly because the animation is done on a seperate thread. I cant implement the deletion in completion:^(BOOL finished){ }, because the Circle class does not know about a circleArray. Any solutions would be helpful, thanks!

• Multiple Socket Connections

  - by BSchlinker

  I need to write a server which accepts connections from multiple client machines, maintains track of connected clients and sends individual clients data as necessary. Sometimes, all clients may be contacted at once with the same message, other times, it may be one individual client or a group of clients. Since I need confirmation that the clients received the information and don't want to build an ACK structure for a UDP connection, I decided to use a TCP streaming method. However, I've been struggling to understand how to maintain multiple connections and keep them idle. I seem to have three options. Use a fork for each incoming connection to create a separate child process, use pthread_create to create an entire new thread for each process, or use select() to wait on all open socket IDs for a connection. Recommendations as to how to attack this? I've begun working with pthreads but since performance will likely not be an issue, multicore processing is not necessary and perhaps there is a simpler way.

• How do ansynchronous methods work

  - by Polaris878

  Hello, I'm wondering if anyone can help me understand some asynchronous javascript concepts... Say I make an asynch ajax call like so: xmlhttp=new XMLHttpRequest(); xmlhttp.onreadystatechange= myFoo; xmlhttp.open("GET",url,true); Here is my callback function: function myFoo() { if (xmlhttp.readyState==4) { if (xmlhttp.status==200) { // Success message } else { // some error message } } } Now, where and when does the execution path start again? Once I make the call to open(), does execution continue directly below the open() and another "thread" enters the asynch function once the ajax request has been completed? Or, does the browser wait for the request to complete, make the Asynch call, and then execution continues right after the open? Thanks!

• spring web application context is not loaded from jar file in WEB-INF/lib when running tomcat in eclipse

  - by Remy J

  I am experimenting with spring, maven, and eclipse but stumbling on a weird issue. I am running Eclipse Helios SR1 with the STS (Spring tools suite) plugin which includes the Maven plugin also. What i want to achieve is a spring mvc webapp which uses an application context loaded from a local application context xml file, but also from other application contexts in jar files dependencies included in WEB-INF/lib. What i'd ultimately like to do is have my persistence layer separated in its own jar file but containing its own spring context files with persistence specific configuration (e.g a jpa entityManagerFactory for example). So to experiment with loading resources from jar dependencies, i created a simple maven project from eclipse, which defines an applicationContext.xml file in src/main/resources Inside, i define a bean <bean id="mybean" class="org.test.MyClass" /> and create the class in the org.test package I run mvn-install from eclipse, which generates me a jar file containing my class and the applicationContext.xml file: testproj.jar |_META-INF |_org |_test |_MyClass.class |_applicationContext.xml I then create a spring mvc project from the Spring template projects provided by STS. I have configured an instance of Tomcat 7.0.8 , and also an instance of springSource tc Server within eclipse. Deploying the newly created project on both servers works without problem. I then add my previous project as a maven dependency of the mvc project. the jar file is correctly added in the Maven Dependencies of the project. In the web.xml that is generated, i now want to load the applicationContext.xml from the jar file as well as the existing one generated for the project. My web.xml now looks like this: org.springframework.web.context.ContextLoaderListener <!-- Processes application requests --> <servlet> <servlet-name>appServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value> classpath*:applicationContext.xml, /WEB-INF/spring/appServlet/servlet-context.xml </param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>appServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> Also, in my servlet-context.xml, i have the following: <context:component-scan base-package="org.test" /> <context:component-scan base-package="org.remy.mvc" /> to load classes from the jar spring context (org.test) and to load controllers from the mvc app context. I also change one of my controllers in org.remy.mvc to autowire MyClass to verify that loading the context has worked as intended. public class MyController { @Autowired private MyClass myClass; public void setMyClass(MyClass myClass) { this.myClass = myClass; } public MyClass getMyClass() { return myClass; } [...] } Now this is the weird bit: If i deploy the spring mvc web on my tomcat instance inside eclipse (run on server...) I get the following error : org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping#0': Initialization of bean failed;

• Rails 3 functional optionally testing caching

  - by Stephan

  Generally, I want my functional tests to not perform action caching. Rails seems to be on my side, defaulting to config.action_controller.perform_caching = false in environment/test.rb. This leads to normal functional tests not testing the caching. So how do I test caching in Rails 3. The solutions proposed in this thread seem rather hacky or taylored towards Rails 2: How to enable page caching in a functional test in rails? I want to do something like: test "caching of index method" do with_caching do get :index assert_template 'index' get :index assert_template '' end end Maybe there is also a better way of testing that the cache was hit?

• Identify cause of hundreds of AJP threads in Tomcat

  - by Rich

  We have two Tomcat 6.0.20 servers fronted by Apache, with communication between the two using AJP. Tomcat in turn consumes web services on a JBoss cluster. This morning, one of the Tomcat machines was using 100% of CPU on 6 of the 8 cores on our machine. We took a heap dump using JConsole, and then tried to connect JVisualVM to get a profile to see what was taking all the CPU, but this caused Tomcat to crash. At least we had the heap dump! I have loaded the heap dump into Eclipse MAT, where I have found that we have 565 instances of java.lang.Thread. Some of these, obviously, are entirely legitimate, but the vast majority are named "ajp-6009-XXX" where XXX is a number. I know my way around Eclipse MAT pretty well, but haven't been able to find an explanation for it. If anyone has some pointers as to why Tomcat may be doing this, or some hints on finding out why using Eclipse MAT, that'd be appreciated!

• attaching linq to sql datacontext to httpcontext in business layer

  - by rap-uvic

  Hello all, I need my linq to sql datacontext to be available across my business/data layer for all my repository objects to access. However since this is a web app, I want to create and destroy it per request. I'm wondering if having a singleton class that can lazily create and attach the datacontext to current HttpContext would work. My question is: would the datacontext get disposed automatically when the request ends? Below is the code for what I'm thinking. Would this accomplish my purpose: have a thread-safe datacontext instance that is lazily available and is automatically disposed when the request ends? public class SingletonDC { public static NorthwindDataContext Default { get { NorthwindDataContext defaultInstance = (NorthwindDataContext)System.Web.HttpContext.Current.Items["datacontext"]; if (defaultInstance == null) { defaultInstance = new NorthwindDataContext(); System.Web.HttpContext.Current.Items.Add("datacontext", defaultInstance); } return defaultInstance; } } }

• C builder RAD 2010 RTL/VCL Application->Terminate() Function NOT TERMINATING THE APPLICATION

  - by ergey

  Hello, I have problem descriebed also here: http://www.delphigroups.info/3/9/106748.html I have tryed almost all forms of placing Application-Terminate() func everywhere in the code, following and not 'return 0', 'ExitProcess(0)', 'ExitThread(0)', exit(0). None working variant closes the app. Instead the code after Application-Terminate() statement is running. I have two or more threads in the app. I tryed calling terminate func in created after execution threads and in main thread. Also this is not related (as i can imagine) with CodeGuard / madExcept (i have turned it off and on, no effect). CodeGuard turning also did not do success. What i should do to terminate all the threads in c builder 2010 application and then terminate the process? Thank you.

• How do you implement Software Transactional Memory?

  - by Joseph Garvin

  In terms of actual low level atomic instructions and memory fences (I assume they're used), how do you implement STM? The part that's mysterious to me is that given some arbitrary chunk of code, you need a way to go back afterward and determine if the values used in each step were valid. How do you do that, and how do you do it efficiently? This would also seem to suggest that just like any other 'locking' solution you want to keep your critical sections as small as possible (to decrease the probability of a conflict), am I right? Also, can STM simply detect "another thread entered this area while the computation was executing, therefore the computation is invalid" or can it actually detect whether clobbered values were used (and thus by luck sometimes two threads may execute the same critical section simultaneously without need for rollback)?

• Gmail rejects emails. Openspf.net fails the tests

  - by pablomedok

  I've got a problem with Gmail. It started after one of our trojan infected PCs sent spam for one day from our IP address. We've fixed the problem, but we got into 3 black lists. We've fixed that, too. But still every time we send an email to Gmail the message is rejected: So I've checked Google Bulk Sender's guide once again and found an error in our SPF record and fixed it. Google says everything should become fine after some time, but this doesn't happen. 3 weeks already passed but we still can't send emails to Gmail. Our MX setup is a bit complex, but not too much: We have a domain name delo-company.com, it has it's own mail @delo-company.com (this one is fine, but the problems are with sub-domain name corp.delo-company.com). Delo-company.com domain has several DNS records for the subdomain: corp A 82.209.198.147 corp MX 20 corp.delo-company.com corp.delo-company.com TXT "v=spf1 ip4:82.209.198.147 ~all" (I set ~all for testing purposes only, it was -all before that) These records are for our corporate Exchange 2003 server at 82.209.198.147. Its LAN name is s2.corp.delo-company.com so its HELO/EHLO greetings are also s2.corp.delo-company.com. To pass EHLO check we've also created some records in delo-company.com's DNS: s2.corp A 82.209.198.147 s2.corp.delo-company.com TXT "v=spf1 ip4:82.209.198.147 ~all" As I understand SPF verifications should be passed in this way: Out server s2 connects to MX of the recepient (Rcp.MX): EHLO s2.corp.delo-company.com Rcp.MX says Ok, and makes SPF check of HELO/EHLO. It does NSlookup for s2.corp.delo-company.com and gets the above DNS-records. TXT records says that s2.corp.delo-company.com should be only from IP 82.209.198.147. So it should be passed. Then our s2 server says RCPT FROM: Rcp.MX` server checks it, too. The values are the same so they should also be positive. Maybe there is also a rDNS check, but I'm not sure what is checked HELO or RCPT FROM. Our PTR record for 82.209.198.147 is: 147.198.209.82.in-addr.arpa. 86400 IN PTR s2.corp.delo-company.com. To me everything looks fine, but anyway all emails are rejected by Gmail. So, I've checked MXtoolbox.com - it says everything is fine, I passed http://www.kitterman.com/spf/validate.html Python check, I did 25port.com email test. It's fine, too: Return-Path: <[email protected]> Received: from s2.corp.delo-company.com (82.209.198.147) by verifier.port25.com id ha45na11u9cs for <[email protected]>; Fri, 2 Mar 2012 13:03:21 -0500 (envelope-from <[email protected]>) Authentication-Results: verifier.port25.com; spf=pass [email protected] Authentication-Results: verifier.port25.com; domainkeys=neutral (message not signed) [email protected] Authentication-Results: verifier.port25.com; dkim=neutral (message not signed) Authentication-Results: verifier.port25.com; sender-id=pass [email protected] Content-class: urn:content-classes:message MIME-Version: 1.0 Content-Type: multipart/alternative; boundary="----_=_NextPart_001_01CCF89E.BE02A069" Subject: test Date: Fri, 2 Mar 2012 21:03:15 +0300 X-MimeOLE: Produced By Microsoft Exchange V6.5 Message-ID: <[email protected]> X-MS-Has-Attach: X-MS-TNEF-Correlator: Thread-Topic: test Thread-Index: Acz4jS34oznvbyFQR4S5rXsNQFvTdg== From: =?koi8-r?B?89XQ0tXOwMsg8MHXxcw=?= <[email protected]> To: <[email protected]> I also checked with [email protected], but it FAILs all the time, no matter which SPF records I make: <s2.corp.delo-company.com #5.7.1 smtp;550 5.7.1 <[email protected]>: Recipient address rejected: SPF Tests: Mail-From Result="softfail": Mail From="[email protected]" HELO name="s2.corp.delo-company.com" HELO Result="softfail" Remote IP="82.209.198.147"> I've filled Gmail form twice, but nothing happens. We do not send spam, only emails for our clients. 2 or 3 times we did mass emails (like New Year Greetings and sales promos) from corp.delo-company.com addresses, but they where all complying to Gmail Bulk Sender's Guide (I mean SPF, Open Relays, Precedence: Bulk and Unsubscribe tags). So, this should be not a problem. Please, help me. What am I doing wrong? UPD: I also tried Unlocktheinbox.com test and the server also fails this test. Here is the result: http://bit.ly/wYr39h .

• Caching generated QR Code

  - by Michal K

  I use zxing to encode a qr code and store it as a bitmap and then show it in ImageView. Since the image generation time is significant I'm planning to move it to a separate thread (AsyncTaskLoader will be fine I think). The problem is - it's an image and I know that to avoid memory leaks one should never store a strong reference to it in an Activity. So how would you do it? How to cache an image to survive config changes (phone rotation) and generally avoid generating it onCreate()? Just point me in the right direction, please.

• sending instant messages through python (msn)

  - by code_by_night

  ok I am well aware there are many other questions about this, but I have been searching and have yet to find a solid proper answer that doesnt revolve around jabber or something worse. (no offense to jabber users, just I don't want all the extras that come with it) I currently have msnp and twisted.words, I simply want to send and receive messages, have read many examples that have failed to work, and msnp is poorly documented. My preference is msnp as it requires much less code, I'm not looking for something complicated. Using this code I can login, and view my friends that are online (can't send them messages though.): import msnp import time, threading msn = msnp.Session() msn.login('[email protected]', 'XXXXXX') msn.sync_friend_list() class MSN_Thread(threading.Thread): def run(self): msn.start_chat("[email protected]") #this does not work while True: msn.process() time.sleep(1) start_msn = MSN_Thread() start_msn.start() I hope I have been clear enough, its pretty late and my head is not in a clear state after all this msn frustration. edit: since it seems msnp is extremely outdated could anyone recommend with simple examples on how I could achieve this? Don't need anything fancy that requires other accounts.

• Optimising local image loading/rendering on iPhone

  - by Tricky

  Hi, I'm looking to create an interface where the user can navigate through large volumes of images. Each image has a thumbnail of 128x128 that I wish to display and will be kind of similar to coverflow in operation. I have this all working in principle but am becoming stuck when navigating through content at speed. The interface begins to stutter and becoming jerky. I believe this is primarily because of disk i/o and the cost of rendering each image. Is there anyway this can be handed over to a seperate thread simply? Defaulting to a greyed out thumbnail until the image has loaded? How have Apple managed to achieve this in coverflow? Many thanks,

• Multiple port asynchronous I/O over serialport in C#

  - by firoso

  I'm trying to write a test application for serial I/O (RS-232) with multiple units in C# and I'm running into an issue with my lack of threading experience so I'm soliciting feedback for a best known method. I've got a pool of COM ports COM1-16 each of which can read/write at any time and I need to be able to manage them simultaneously. Is this a situation for a thread pool? What is some guidance on structuring this applet? Edit: Upon review I was wondering is I really even need to do asynchronous threads here, I could just maintain states for each COM-port and do flow logic (i.e., statemachine) for each COM-port individually.
