  • Manipulating jQuery to retrieve the onclick function of an item which lies directly below the curren

    - by Stevie Jenowski
    First off, I want to thank you for looking into my question as I really do appreciate your time. I've built a list of items using php by having a foreach loop cycle through an associative array printing the array data as parameters of an onclick function call and gives each item it cycles through an ID of $thecount. All items retrieved have the same parent div and calls the very same onclick function, only with 11 different parameters. My question is how do I go about calling the onClick("function();") of an item directly below the current focus, making it the new focus, only without a physical click? If this is confusing to you whatsoever, I'm essentially building a dynamic playlist, and I've already implemented the listener for when the player's current item has finished playing, Now I'm having trouble grasping how I'd go about having the next item in the list become the new focus while also calling it's specific onClick() function once the player returns that it has finished with the current file. All without any user interaction besides the initial play call. If it helps I'm using the most recent release of Longtails' JW Player and once again thank you very much for your time!

  • performSelectorInBackground: using self.object ?

    - by Emil
    Hey. I am trying to load an image for a custom tableViewCell. The code gets run from the CustomCell-class (CustomCell.h) from [cell performSelectorInBackground:@selector(loadImageFromURL:) withObject:[NSURL URLWithString:urlString]]; in the cellForRowAtIndexPath:-function. Cell gets created here: CustomCell *cell = (CustomCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil){ NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil]; for (id currentObject in topLevelObjects){ if ([currentObject isKindOfClass:[CustomCell class]]){ cell = (CustomCell *) currentObject; break; } } } CustomCell.h: // ... IBOutlet UIImageView *cellImage; } - (void) loadImageFromURL:(NSURL *)url; // … CustomCell.m: - (void) loadImageFromURL:(NSURL *)url { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; NSLog(@"Loading image..."); [loadingImage startAnimating]; [self.cellImage setImageWithURL:url]; [loadingImage stopAnimating]; NSLog(@"Done loading image..."); [pool release]; } setImageWithURL: is a function from the SDWebImage-framework that rs has made. The real error is that the image doesen't show up. EDIT: When I cleared the app's cache, the images didn't show up anymore. EDIT: Seems like URL is nil for some reason. Am I passing the object in the selector correctly? Can you see anything wrong? Thanks.

  • UINavigationController navigation stack problems in Landscape Mode

    - by David F
    I have a iPhone application that I am currently converting to a Universal Binary to work with the iPad. I have successfully implemented everything I need in terms of layout so that full landscape functionality is now supported in my app (previously I primarily used portrait mode to display content). But, I have one strange problem, and it ONLY occurs in landscape mode: when I push a view controller onto the stack, it takes two taps on the back button to return to the previous view controller!!! The first tap shows a blank view, but with the same name on the left-side back navigation button, the second tap takes the controller back to previous view like it should. I don't have an iPad to test, so I am relying on the simulator. The problem does not show up on the iPhone and doesn't show up if you rotate back to portrait mode. My app consists of a tabbarcontroller with navigation controllers loaded for its vc's: //application delegate - (void)applicationDidFinishLaunching:(UIApplication *)application //.... WebHelpViewController *vc8 = [[WebHelpViewController alloc] init]; UINavigationController *nv8 = [[UINavigationController alloc] initWithRootViewController:vc8]; [self.tabBarController setViewControllers:[NSArray arrayWithObjects:nv1,nv2,nv3,nv4,nv5,nv6,nv7,nv8,nil]]; To implement landscape capability, the UITabBarController is overridden to autorotate when required: //CustomTabBarController.m - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return [[(UINavigationController *)self.selectedViewController topViewController] shouldAutorotateToInterfaceOrientation:interfaceOrientation]; } ... works fine. I navigate into new views using this method SomeViewController *vc = [[SomeViewController alloc] init]; [self.navigationController pushViewController:vc animated:YES]; [vc release]; Has anyone encountered this problem, and do they know if it's only a simulation error?

  • What is the correct way to implement a massive hierarchical, geographical search for news?

    - by Philip Brocoum
    The company I work for is in the business of sending press releases. We want to make it possible for interested parties to search for press releases based on a number of criteria, the most important being location. For example, someone might search for all news sent to New York City, Massachusetts, or ZIP code 89134, sent from a governmental institution, under the topic of "traffic". Or whatever. The problem is, we've sent, literally, hundreds of thousands of press releases. Searching is slow and complex. For example, a press release sent to Queens, NY should show up in the search I mentioned above even though it wasn't specifically sent to New York City, because Queens is a subset of New York City. We may also want to implement "and" and "or" and negation and text search to the query to create complex searches. These searches also have to be fast enough to function as dynamic RSS feeds. I really don't know anything about search theory, or how it's properly done. The way we are getting by right now is using a data mart to store the locations the releases were sent to in a single table. However, because of the subset thing mentioned above, the data mart is gigantic with millions of rows. And we haven't even implemented cities yet, and there are about 50,000 cities in the United States, which will exponentially increase the size of the data mart by so much I'm afraid it just won't work anymore. Anyway, I realize this is not a simple question and there won't be a "do this" answer. However, I'm hoping one of you can point me in the right direction where I can learn about how massive searches are done? Because I really know nothing about it. And such a search engine is turning out to be incredibly difficult to make. Thanks! I know there must be a way because if Google can search the entire internet we must be able to search our own database :-)

  • -[NSCFData writeStreamHandleEvent:]: unrecognized selector sent to instance in a stream callback

    - by user295491
    Hi everyone, I am working with streams and sockets in iPhone SDK 3.1.3 the issue is when the program accept a callback and I want to handle this writestream callback the following error is triggered " Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: ' -[NSCFData writeStreamHandleEvent:]: unrecognized selector sent to instance 0x17bc70'" But I don't know how to solve it because everything seems fine. Even when I run the debugger there is no error the program works. Any hint here will help! The code of the callback is: void myWriteStreamCallBack (CFWriteStreamRef stream, CFStreamEventType eventType, void *info){ NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; Connection *handlerEv = [(Connection *)info retain] autorelease]; [handlerEv writeStreamHandleEvent:eventType]; [pool release]; } The code of the writeStreamHandleEvent: - (void)writeStreamHandleEvent:(CFStreamEventType) eventType{ switch(eventType) { case kCFStreamEventOpenCompleted: writeStreamOpen = YES; break; case kCFStreamEventCanAcceptBytes: NSLog(@"Writing in the stream"); [self writeOutgoingBufferToStream]; break; case kCFStreamEventErrorOccurred: error = CFWriteStreamGetError(writeStream); fprintf(stderr, "CFReadStreamGetError returned (%ld, %ld)\n", error.domain, error.error); CFWriteStreamUnscheduleFromRunLoop(writeStream, CFRunLoopGetCurrent(),kCFRunLoopCommonModes); CFWriteStreamClose(writeStream); CFRelease(writeStream); break; case kCFStreamEventEndEncountered: CFWriteStreamUnscheduleFromRunLoop(writeStream, CFRunLoopGetCurrent(),kCFRunLoopCommonModes); CFWriteStreamClose(writeStream); CFRelease(writeStream); break; } } The code of the stream configuration: CFSocketContext ctx = {0, self, nil, nil, nil}; CFWriteStreamSetClient (writeStream,registeredEvents, (CFWriteStreamClientCallBack)&myWriteStreamCallBack,(CFStreamClientContext *)(&ctx) ); CFWriteStreamScheduleWithRunLoop (writeStream, CFRunLoopGetCurrent(), kCFRunLoopDefaultMode); You can see that there is nothing strange!, well at least I don't see it. Thank you in advance.

  • Does anyone knows any Train-table-api service?

    - by DaNieL
    Hi guys, im wondering if there is any online service who provide API about the train timetables (arrivals, departure, etch..), at least for the european stations. I know www.bahn.de, who provide the accurated timetables for many european countries, but i didin't find any similar to a api service. My goal (well, just a future-project) is to develope an application like gmaps, but instead of giving the car-trip i would like to give the train-trip.. you know, the user set the departure day, time and station, then the first arrival, maybe then add another one, and so on. So, there is something like, that can be queryed by php/python/javascript? Edit: if can help, im wondering to build a service to plan an inter-rail trip! (and any help will be really appreciate) Im stuck. Google's public-service api rely on the information that every local company makes avaiable, much branches are missing (for example, is almost impossible to use it to build an itinerary that touches two or more regions of Europe. As i said before, the only service that i know doing it good is the bahn.de, they really have all the data.. but no api. I tryed to parse theyre result page (in order to use them as API), but seem like the markup is been build exactly to avoid that.. maybe they have business plans behind that or whatever, but i dont think they will ever release some API.. so, my project is going on without this function (p.s: my project is about non-profit cultural organizations, we wont make war to anyone ;P) @El Goorf: if you find a way, and consider the idea of sharing it, count on my hand if need help!

  • Question about WeakReferences

    - by Impz0r
    Hey there, I've got a question regarding WeakReferences. I'm right now in the process of writing a "Resource Manager" who hast to keep references to created texture objects. I have a Dictionary like: Dictionary<uint, WeakReference> Where the first is, as you allready may guessed, the Resource Id and the second param is a WeakReference to the Resource itself. Right now my Resources do have a method to free themselfes from their Owner (i.e. Resource Manager). They do so in calling a method at the Resource Manger while passing a this reference to it. The ResMgr does lookup if it is a resource he keeps bookmark of and if so, does something like this: WeakReference result; if (m_Resources.TryGetValue(ResourceId, out result)) { if (result.IsAlive) return; (result.Target as Resource).free(); // free for good m_Resources.Remove(ResourceId); } The Problem I'm having is that the part after: if (result.IsAlive) is never reached because there are still leftover references to the Resource. The thing is, I do only have one Reference of the Resource in question and it releases itself like: resource.free(); // calls internally its owner (i.e. ResMgr) resource = null; I guess the left over reference would be the "resource" variable, but I cannot set it to null, because I do have to call free first. Quite a dilema... Well what I wanted to achive with this is a Resource Manager who keeps references to its owning Resources and release them ONLY if there is no reference left to not screw up something. Any idea how I may solve this in a clean fashion? Thanks in advance! Mfg Imp

  • Getting hardware floating point with android NDK

    - by Goz
    Hi All, I've begun playing with the android NDK. One of the things I've just learnt is about creating an application.mk file to specify the armv7 abi. I'm building the san-angeles example with the following parameters. APP_MODULES := sanangeles APP_PROJECT_PATH := $(call my-dir)/../ APP_OPTIM := release APP_ABI := armeabi-v7a However this seems to run at exactly the same speed as it did before (ie badly). Am I just GL limited and not CPU limited or is something wrong here? I have noticed when I compile that I get the following command line options emitted: -march=armv7-a -mfloat-abi=softfp -mfpu=vfp -mthumb The thing that worries me there is the "softfp". There IS mention of the v7 abi, the VFP fpu stuff and I'm guessing the "thumb" refers to the "thumb-2" instructions (Though I don't know what exactly these are). However that "softfp" does concern me. Shouldn't it be "hardfp"? Anyone got any ideas on these questions? I think I'm probably about ready to start implementing some GL ES 2.0 code for my HTC Desire but I'd like to make sure I'm getting the best possible speed out of it :) Cheers in advance!

  • iPhone - UIViewController not rotating when device orientation changes

    - by Ryu
    I have got my own custom UIViewController, which contains a UIScrollView with an UIImageView as it's subview. I would like to make the image to auto rotate when device orientation changes, but it doesn't seem to be working... In the header file, I've got; @interface MyViewController : UIViewController <UIScrollViewDelegate> { IBOutlet UIScrollView *containerView; UIImageView *imageView; } These components are initialised in the loadView function as below; containerView = [[UIScrollView alloc] initWithFrame:frame]; NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:@"http://..."]]; UIImage *image = [[UIImage alloc] initWithData:data]; imageView = [[UIImageView alloc] initWithImage:image]; [image release]; [containerView addSubview:imageView]; And I have added the following method, assuming that's all I need to make the view auto-rotate... -(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } MyViewController loads fine with the image I've specified to grab from the URL, and the shouldAutorotate... function is being called, with the correct UIInterfaceOrientation, when I flip the device too. However, didRotateFromInterfaceOrientation method do not get called, and the image doesn't seem to rotate itself... Could someone please point out what I need to add, or what I have done wrong here? Thanks in advance!

  • Windows Azure ASP.NET MVC Role behaves strangely when redirecting from HTTP to HTTPS

    - by Rinat Abdullin
    Subj. I've got an ASP.NET 2 MVC Worker Role Application, that does not differ much from the default template. When attempting redirect from HTTP to HTTPS (this happens when we access constroller secured by the usual RequireSSL attribute implementation) we get blank page with "Bad Request" message. IntelliTrace shows this: Thrown: "The file '/Views/Home/LogOnUserControl.aspx' does not exist." (System.Web.HttpException) Call stack is really short: [External Code] App_Web_vfahw7gz.dll!ASP.views_shared_site_master.__Render__control1(System.Web.UI.HtmlTextWriter __w = {unknown}, System.Web.UI.Control parameterContainer = {unknown}) [External Code] App_Web_bsbqxr44.dll!ASP.views_home_index_aspx.ProcessRequest(System.Web.HttpContext context = {unknown}) [External Code] User control reference is the usual one in /Views/Shared/Site.Master: <div id="logindisplay"> <% Html.RenderPartial("LogOnUserControl"); %> </div> And partial view LogOnUserControl.ashx is located in Views/Shared (and it is ASHX, not ASPX). Problem shows up, when we try to access site pages, that require auth and redirect. These pages are secured by RequireSSL attribute (Redirect == true): [AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true, AllowMultiple = false)] public sealed class RequireSslAttribute : FilterAttribute, IAuthorizationFilter { public bool Redirect { get; set; } // Methods public void OnAuthorization(AuthorizationContext filterContext) { // this get's messy, when we are running custom ports // within the local dev fabric. // hence we disable code in the debug #if !DEBUG if (filterContext == null) { throw new ArgumentNullException("filterContext"); } if (filterContext.HttpContext.Request.IsSecureConnection) return; var canRedirect = string.Equals(filterContext.HttpContext.Request.HttpMethod, "GET", StringComparison.OrdinalIgnoreCase); if (canRedirect && Redirect) { var builder = new UriBuilder { Scheme = "https", Host = filterContext.HttpContext.Request.Url.Host, Path = filterContext.HttpContext.Request.RawUrl }; filterContext.Result = new RedirectResult(builder.ToString()); } else { throw new HttpException(0x193, "Access forbidden. The requested resource requires an SSL connection."); } #endif } } Obviously we compile in RELEASE for this case. Does anybody have any idea, what could cause this strange exception and how to get rid of it?

  • SQL Server 2000 intermittent connection exceptions on production server - specific environment probl

    - by StickyMcGinty
    We've been having intermittent problems causing users to be forcibly logged out of out application. Our set-up is ASP.Net/C# web application on Windows Server 2003 Standard Edition with SQL Server 2000 on the back end. We've recently performed a major product upgrade on our client's VMWare server (we have a guest instance dedicated to us) and whereas we had none of these issues with the previous release the added complexity that the new upgrade brings to the product has caused a lot of issues. We are also running SQL Server 2000 (build 8.00.2039, or SP4) and the IIS/ASP.NET (.Net v2.0.50727) application on the same box and connecting to each other via a TCP/IP connection. Primarily, the exceptions being thrown are: System.IndexOutOfRangeException: Cannot find table 0. System.ArgumentException: Column 'password' does not belong to table Table. [This exception occurs in the log in script, even though there is clearly a password column available] System.InvalidOperationException: There is already an open DataReader associated with this Command which must be closed first. [This one is occurring very regularly] System.InvalidOperationException: This SqlTransaction has completed; it is no longer usable. System.ApplicationException: ExecuteReader requires an open and available Connection. The connection's current state is connecting. System.Data.SqlClient.SqlException: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. And just today, for the first time: System.Web.UI.ViewStateException: Invalid viewstate. We have load tested the app using the same number of concurrent users as the production server and cannot reproduce these errors. They are very intermittent and occur even when there are only 8/9/10 user connections. My gut is telling me its ASP.NET - SQL Server 2000 connection issues.. We've pretty much ruled out code-level Data Access Layer errors at this stage (we've a development team of 15 experienced developers working on this) so we think its a specific production server environment issue.

  • Rails 3 with Ruby 1.9.1 on Heroku

    - by stephen murdoch
    I've decided that I am going to man-up and start using Rails 3 from now on but the following note found here puts me off a bit: Note that Ruby 1.8.7 has marshaling bugs that crash both Rails 2.3.x and Rails 3.0.0. Ruby 1.9.1 outright segfaults on Rails 3.0.0, so if you want to use Rails 3 with 1.9.x, jump on 1.9.2 trunk for smooth sailing. I use Heroku for my deployment and as far as I am aware they do not plan to add 1.9.2 to the stack until it's stable (which might be in August) so I was thinking of doing it with 1.9.1. and seeing what happens. I know that there is a 3rd beta release now but the comments on the blog imply that it's still a little bit buggy. Is DHH inferring that you shouldn't touch Rails 3 at all if you are on 1.9.1? What are other Heroku-ists doing regarding Rails 3? Anyone using it for any production apps? I guess I'll only know once I've tried but any advice would be nice.

  • How to install OpenCV 2.0 on win32

    - by Jive Dadson
    I need to install OpenCV on Win32. I do not have it installed currently. I downloaded OpenCV-2.0.0a-win32.exe and ran it. What the heck do I do now? There are no .lib's and whatnot. I found some instructions for building the release using cmake at http://opencv.willowgarage.com/wiki/InstallGuide . I downloaded the latest and greatest cmake, and tried to follow the instructions, but I was guessing. No joy. I specified VC++9 when I did the "configure," but cmake built a VC++ 6 dsw file. No vcproj. I converted the dsw into a vc++9 vcproj anyway, just to see if it would work. Nope. It compiled lots of files, but many failed because it could not find omp.h. Sure enough, it's not there, anywhere. The build log said, 'A tool returned an error code from "Performing Custom Build Step".' I am lost. Ideally, I would like to find a full installation with all the files pre-built for Win32 vc++ 2008. Failing that, I need instructions that even I can follow. Short sentences and small words, but lots of them. Please help! UPDATE: I tried to build just CXCORE. It complained, "cannot open file 'VCOMPD.lib'" There's that OMP again.

  • Verifying existence of name and password in NSUserDefaults to Skip a login/Screen

    - by Michael Robinson
    I have a Tabbar/Tableview App that modally loads a Login/Signup view when the app loads, I have set up a Root.plist in a settings bundle for the name and password and have successfully retrieved the items. I want to be able to do two things: 1) Do a test to see if the NSUserDefault Strings are empty and if so load the Login/Signup view. 2) If the strings are available then use the string contents to login to my Webservice.

  • JAAS and WebLogic 10.3: Granting specific codebase permissions to a JAR bundled within an EAR

    - by Jason
    Here's my scenario: I have a JAR within the APP-INF/lib of my EAR, to be deployed within WebLogic 10g Release 3 against which I wish to grant specific permissions. e.g., grant codebase "file:/c:/somedir/my.jar" { permission java.net.SocketPermission "*:-","accept,connect,listen, resolve"; permission java.net.SocketPermission "localhost:-","accept,connect,listen,resolve"; permission java.net.SocketPermission "127.0.0.1:-","accept,connect,listen,resolve"; permission java.net.SocketPermission "230.0.0.1:-","accept,connect,listen,resolve"; permission java.util.PropertyPermission "*", "read,write"; permission java.lang.RuntimePermission "*"; permission java.io.FilePermission "<<ALL FILES>>","read,write,delete"; permission javax.security.auth.AuthPermission "*"; permission java.security.SecurityPermission "*"; }; Questions: Where is the best place to define this grant - in the java.policy of the JRE, WL server's weblogic.policy, or within a XML packaged within the EAR How do I define the codebase URL to the JAR? The examples I have seen have an explicit reference to the JAR on the file system, however I am deploying the JAR packaged up within an EAR. Thanks!

  • Why can't I initialize a class through a setter?

    - by Rob emenaker
    If I have a custom class called Tires: #import <Foundation/Foundation.h> @interface Tires : NSObject { @private NSString *brand; int size; } @property (nonatomic,copy) NSString *brand; @property int size; - (id)init; - (void)dealloc; @end ============================================= #import "Tires.h" @implementation Tires @synthesize brand, size; - (id)init { if (self = [super init]) { [self setBrand:[[NSString alloc] initWithString:@""]]; [self setSize:0]; } return self; } - (void)dealloc { [super dealloc]; [brand release]; } @end And I synthesize a setter and getter in my View Controller: #import <UIKit/UIKit.h> #import "Tires.h" @interface testViewController : UIViewController { Tires *frontLeft, *frontRight, *backleft, *backRight; } @property (nonatomic,copy) Tires *frontLeft, *frontRight, *backleft, *backRight; @end ==================================== #import "testViewController.h" @implementation testViewController @synthesize frontLeft, frontRight, backleft, backRight; - (void)viewDidLoad { [super viewDidLoad]; [self setFrontLeft:[[Tires alloc] init]]; } - (void)dealloc { [super dealloc]; } @end It dies after [self setFrontLeft:[[Tires alloc] init]] comes back. It compiles just fine and when I run the debugger it actually gets all the way through the init method on Tires, but once it comes back it just dies and the view never appears. However if I change the viewDidLoad method to: - (void)viewDidLoad { [super viewDidLoad]; frontLeft = [[Tires alloc] init]; } It works just fine. I could just ditch the setter and access the frontLeft variable directly, but I was under the impression I should use setters and getters as much as possible and logically it seems like the setFrontLeft method should work. This brings up an additional question that my coworkers keep asking in these regards (we are all new to Objective-C); why use a setter and getter at all if you are in the same class as those setters and getters.

  • Running directx SDK samples on a Windows Mobile 6.1 device

    - by Sil
    I tried to run the directx samples from ..\Windows Mobile 6 SDK\Samples\PocketPC\CPP\win32\directx\d3dm\tutorials on a Samsung Omnia and on the emulator and it doesn't work because of a deployment error. I am using Microsoft Visual Studio 2008 and have installed Windows Mobile SDK Standard and Professional refresh. The device is correctly plugged in and set up for active sync (I know this because other samples work, also a creating Win32 smart device application and running it works). When I try to run a directx sample application it compiles without errors but the message: " There were deployment errors, Continue? Yes/No" appears If I manually copy the application from the debug folder to the device and run it from there, it works. The same deployment error message appears if I try it on an emulator. Other applications are deploying successfully. Is there any way to make the deployment work? Maybe there is an obscure option I need to set... What I do is: Connect the Mobile device to the PC, Open Visual Studio 2008, Open a directx sample project, Click Run (in Debug or Release mode).

  • Can memory be cleaned up?

    - by Tom
    I am working in Delphi 5 (with FastMM installed) on a Win32 project, and have recently been trying to drastically reduce the memory usage in this application. So far, I have cut the usage nearly in half, but noticed something when working on a separate task. When I minimized the application, the memory usage shrunk from 45 megs down to 1 meg, which I attributed to it paging out to disk. When I restored it and restarted working, the memory went up only to 15 megs. As I continued working, the memory usage slowly went up again, and a minimize and restore flushed it back down to 15 megs. So to my thinking, when my code tells the system to release the memory, it is still being held on to according to Windows, and the actual garbage collection doesn't kick in until a lot later. Can anyone confirm/deny this sort of behavior? Is it possible to get the memory cleaned up programatically? If I keep using the program without doing this manual flush, I get an out of memory error after a while, and would like to eliminate that. Thanks.

  • Problems referencing build output from TFS Build and Visual Studio

    - by pmdarrow
    Here's what I'm trying to do: I have two solutions - one for my main application and its associated projects and another for my database (VS .dbproj) and its associated projects. What I'd like to do is include the output from the database project (a .dbschema and some SQL scripts) in my WiX installer (which exists in the main application solution.) This involves having TFS build the DB solution immediately before the main application solution. I've got that part working properly, but I'm having trouble referencing the output of the DB solution from my installer. I'm using relative paths to reference the DB project output in my WiX installer (e.g. <?define DBProjectOutputDir = "..\..\MyDatabaseSolution\MyDatabaseProject\sql\"?>) which works fine locally, but fails when building via TFS build. This is because TFS Build apparently changes the output dir of each project to one common location. Instead of the path to my database project being ..\..\MyDatabaseSolution\MyDatabaseProject\sql\ like it is when building locally, it gets set to something like ..\..\..\Binaries\Release\. How can I get around this and have a consistent output location to reference from my installer project? I'm using TFS 2005 and VS 2008.

  • How to architect Rails site that can be edited while running?

    - by Chris Kimpton
    Hi, I am writing a Rails app that "scrapes/navigates" some other websites and webservices for content. I am using Mechanize and Savon to do the heavylifting. But given the dynamic nature of the web, I'd like to make my calls to these editable by the admin users of the site - rather than requiring me to release a new version of the site. The actual scraping thread happens async to the website, using the daemons gem. My requirements are: Thinking that the scraping/webservice calling code is quite simple, the easiest route is to make the whole class editable by the admins. Keep a history of the scraping code - so that we can fairly easily revert if we introduce a problem. Initially use the code from the file system, but as soon as thats been edited and stored somewhere, to use that code instead. I am thinking my options are: Store the code in the db (with a history table for the old versions) Store the code in a private git repo somewhere and access that for the history/latest versions. I am thinking the git route might be easiest, given its raison d'etre is to track file history... But perhaps there is a gem/plugin that does all this for me, out of the box? Thanks in advance for any tips/advice. ~chris

  • Is it okay to implement reference counting through composition?

    - by Billy ONeal
    Most common re-usable reference counted objects use private inheritance to implement re-use. I'm not a huge fan of private inheritance, and I'm curious if this is an acceptable way of handling things: class ReferenceCounter { std::size_t * referenceCount; public: ReferenceCounter() : referenceCount(NULL) {}; ReferenceCounter(ReferenceCounter& other) : referenceCount(other.referenceCount) { if (!referenceCount) { referenceCount = new std::size_t(1); other.referenceCount = referenceCount; } else { ++(*referenceCount); } }; ReferenceCounter& operator=(const ReferenceCounter& other) { ReferenceCounter temp(other); swap(temp); return *this; }; void swap(ReferenceCounter& other) { std::swap(referenceCount, other.referenceCount); }; ~ReferenceCounter() { if (referenceCount) { --(*referenceCount); if (!*referenceCount) delete referenceCount; } }; operator bool() const { return referenceCount && (*referenceCount != 0); }; }; class SomeClientClass { HANDLE someHandleThingy; ReferenceCounter objectsStillActive; public: SomeClientClass() { //Construct handle thingy } ~SomeClientClass() { if (objectsStillActive) return; //Release resources }; }; or are there subtle problems with this I'm not seeing?

  • Getting an Android App to Show Up in the market for "Sony Internet TV"(Google TV)

    - by user1291659
    I'm having a bit of trouble getting my app to show up in the market under GoogleTV. I've searched google's official documentation and I don't believe the manifest lists any elements which would invalidate the program; the only hardware requirement specified is landscape mode, wakelock and external storage(neither which should cause it to be filtered for GTV according to the documentation) and I set the uses touchscreen elements "required" attribute to false. below is the AndroidManifest.xml for my project: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.whateversoft" android:versionCode="2" android:versionName="0.1" > <uses-sdk android:minSdkVersion="8" /> <application android:icon="@drawable/ic_launcher" android:label="Color Shafted" android:theme="@style/Theme.NoBackground" android:debuggable="false"> <activity android:label="Color Shafted" android:name=".colorshafted.ColorShafted" android:configChanges = "keyboard|keyboardHidden|orientation" android:screenOrientation = "landscape"> <!-- Set as the default run activity --> <intent-filter > <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:label="Color Shafted Settings" android:name=".colorshafted.Settings" android:theme="@android:style/Theme" android:configChanges = "keyboard|keyboardHidden"> <!-- --> </activity> </application> <!-- DEFINE PERMISSIONS FOR CAPABILITIES --> <uses-permission android:name = "android.permission.WRITE_EXTERNAL_STORAGE"/> <uses-permission android:name = "android.permission.WAKE_LOCK"/> <uses-feature android:name="android.hardware.touchscreen" android:required="false" /> <!-- END OF PERMISSIONS FOR CAPABILITIES --> </manifest> I'm about to start promoting the app after the next major release so its been kind of a bummer since I can't seem to get this to work. Any help would be appreciated, thanks in advance : )

  • What headaches should I expect from using Trac?

    - by Dolph Mathews
    No tool is perfect, and I'm about to start several long-term projects using Trac, and wanted a heads up of the kinds of problems I may or may not experience with it. In other words, Trac meets my needs in the short term, and I've already made the decision to use it, but I want to know what to expect down the road. I am not looking for: "Use product X instead of Trac because..." answers. "Trac is great because..." answers. A comparison to any other specific system. "Trac doesn't support Feature X" answers. I can read the feature list too, thank you very much. I am looking for: "Feature X does not behave as expected..." "Trac behaves oddly when..." "Trac doesn't fully support..." "Trac itself has a known bug that will likely never be fixed..." And especially "Trac can't handle..." etc So, what Trac-induced headaches do I have to look forward to? For future reference, this question was asked while Trac v0.11 was the latest stable release.

  • Application lifecycle and onCreate method in the the android sdk

    - by Leif Andersen
    I slapped together a simple test application that has a button, and makes a noise when the user clicks on it. Here are it's method: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Button b = (Button)findViewById(R.id.easy); b.setOnClickListener(this); } public void onClick(View v) { MediaPlayer mp = MediaPlayer.create(this, R.raw.easy); mp.start(); while(true) { if (!mp.isPlaying()) { mp.release(); break; } } } My question is, why is onCreate acting like it's in a while loop? I can click on the button whenever, and it makes the sound. I might think it was just a property of listeners, but the Button object wasn't a member variable. I thought that Android would just go through onCreate onse, and proceed onto the next lifecycle method. Also, I know that my current way of seeing if the sound is playing is crap...I'll get to that later. :) Thank you.

  • CAScrollLayer doesn't scroll!

    - by Cliff
    Maybe it's because it's late. Whatever the reason I can't figure out why I'm having trouble with a simple CSScrollLayer example I'm trying. I add a 50 pixel Eclipse icon to a view based project and in my initialize method (called from initWithNibName:bundle:) I have this: -(void) initialize { CAScrollLayer *scrollLayer = [CAScrollLayer layer]; scrollLayer.backgroundColor = [[UIColor blackColor] CGColor]; CGRect bounds = self.view.bounds; scrollLayer.bounds = CGRectMake(0, 0, bounds.size.width, bounds.size.height); scrollLayer.contentsRect = CGRectMake(0, 0, bounds.size.width + 800, bounds.size.height + 800); scrollLayer.borderWidth = 2.5; scrollLayer.borderColor = [[UIColor redColor] CGColor]; scrollLayer.position = CGPointMake(self.view.center.x, self.view.center.y - 20); scrollLayer.scrollMode = kCAScrollBoth; [self.view.layer addSublayer:scrollLayer]; UIImage *image = [UIImage imageNamed:@"eclipse32.gif"]; for(int i=0; i<6; i++) { layer = [CALayer layer]; layer.backgroundColor = [[UIColor blackColor] CGColor]; layer.bounds = CGRectMake(0, 0, 100, 100); layer.contents = (id)[image CGImage]; layer.position = CGPointMake(layer.bounds.size.width * i, self.view.center.y); [scrollLayer addSublayer:layer]; } // [button removeFromSuperview]; // [self.view addSubview:button]; // self.view.userInteractionEnabled = YES; [image release]; } The scroll layer shows, the icon is repeated on the layer I have a border around the edge of the screen. Everything is lovely except I can't scroll the icons. I've tried with/without setting scroll mode. I've tried with a single stretched icon that falls off screen. I've tried everything. What am I doing wrong?
