• How to copy depth buffer to CPU memory in DirectX?

  - by Ashwin

  I have code in OpenGL that uses glReadPixels to copy the depth buffer to a CPU memory buffer: glReadPixels(0, 0, w, h, GL_DEPTH_COMPONENT, GL_FLOAT, dbuf); How do I achieve the same in DirectX? I have looked at a similar question which gives the solution to copy the RGB buffer. I've tried to write similar code to copy the depth buffer: IDirect3DSurface9* d3dSurface; d3dDevice->GetDepthStencilSurface(&d3dSurface); D3DSURFACE_DESC d3dSurfaceDesc; d3dSurface->GetDesc(&d3dSurfaceDesc); IDirect3DSurface9* d3dOffSurface; d3dDevice->CreateOffscreenPlainSurface( d3dSurfaceDesc.Width, d3dSurfaceDesc.Height, D3DFMT_D32F_LOCKABLE, D3DPOOL_SCRATCH, &d3dOffSurface, NULL); // FAILS: D3DERR_INVALIDCALL D3DXLoadSurfaceFromSurface( d3dOffSurface, NULL, NULL, d3dSurface, NULL, NULL, D3DX_FILTER_NONE, 0); // Copy from offscreen surface to CPU memory ... The code fails on the call to D3DXLoadSurfaceFromSurface. It returns the error value D3DERR_INVALIDCALL. What is wrong with my code?

• What to call objects that may delete cached data to meet memory constraints?

  - by Brent

  I'm developing some cross-platform software which is intended to run on mobile devices. Both iOS and Android provide low memory warnings. I plan to make a wrapper class that will free cached resources (like textures) when low memory warnings are issued (assuming the resource is not in use). If the resource returns to use, it'll re-cache it, etc... I'm trying to think of what this is called. In .Net, it's similar to a "weak reference" but that only really makes sense when dealing with garbage collection, and since I'm using c++ and shared_ptr, a weak reference already has a meaning which is distinct from the one I'm thinking of. There's also the difference that this class will be able to rebuild the cache when needed. What is this pattern/whatever is called? Edit: Feel free to recommend tags for this question.

• How important is it for a programmer to know how to implement a QuickSort/MergeSort algorithm from memory?

  - by John Smith

  I was reviewing my notes and stumbled across the implementation of different sorting algorithms. As I attempted to make sense of the implementation of QuickSort and MergeSort, it occurred to me that although I do programming for a living and consider myself decent at what I do, I have neither the photographic memory nor the sheer brainpower to implement those algorithms without relying on my notes. All I remembered is that some of those algorithms are stable and some are not. Some take O(nlog(n)) or O(n^2) time to complete. Some use more memory than others... I'd feel like I don't deserve this kind of job if it weren't because my position doesn't require that I use any sorting algorithm other than those found in standard APIs. I mean, how many of you have a programming position where it actually is essential that you can remember or come up with this kind of stuff on your own?

• 13.10 upgrade dropping wifi [on hold]

  - by Daryl

  Almost a complete newb here. After my last upgrade from 12.04 to 13.10 my wifi now randomly drops. The only way I can get a signal back is a shutdown and restart otherwise it shows no network is even available to connect to. Had no problems until the upgrade. Any help would be appreciated.

• How to shrink-to-fit an std::vector in a memory-efficient way?

  - by dehmann

  I would like to 'shrink-to-fit' an std::vector, to reduce its capacity to its exact size, so that additional memory is freed. The standard trick seems to be the one described here: template< typename T, class Allocator > void shrink_capacity(std::vector<T,Allocator>& v) { std::vector<T,Allocator>(v.begin(),v.end()).swap(v); } The whole point of shrink-to-fit is to save memory, but doesn't this method first create a deep copy and then swaps the instances? So at some point -- when the copy is constructed -- the memory usage is doubled? If that is the case, is there a more memory-friendly method of shrink-to-fit? (In my case the vector is really big and I cannot afford to have both the original plus a copy of it in memory at any time.)

• WIFI/LAN not working after Installing Ubuntu 13.10

  - by user183025

  I can't connect to my WIFI after installing Ubuntu 13.10. I tried re-installing it three times (thinking that I did something wrong during the installation) but I still can't connect to my WIFI. It just gives me the message that I'm offline and that I can't connect to my WIFI. I also tried connecting to the internet using LAN cable but with the same results. I tried google but it seems that there's no solution to this yet.... Anybody knows how to solve this? Thanks!

• UINavigationController leak/understanding popViewController

  - by Kamchatka

  Hello, I have a navigation controller and a table view. When someone click on the table view, I do the following: MyViewController *myViewController = [[MyViewController alloc] initWithImage:image]; [image release]; [self.navigationController pushViewController:myViewController animated:YES]; [myViewController release]; myViewController will retain the image. Now, if I go back and forth in the NavigationController, I get a leak because a new MyViewController gets created each time and apparently the popViewController doesn't release the myViewController. My question: Why doesn't popViewController release the controller? How should I handle that? Put the myViewController as a member of my class and check if it already exists instead of creating it each time? Thanks in advance for your help,

• AppEngine JRuby - OutOfMemoryError: Java heap space - can it be solved?

  - by elado

  I use AppEngine JRuby on Rails (SDK version 1.3.3.1) - a problem I encounter often is that after a few requests the server is getting really SLOW, until it dies and throws OutOfMemoryError on the terminal (OSX).

• Faulting DLL (ISAPI Filter)...

  - by Brad

  I wrote this ISAPI filter to rewrite the URL because we had some sites that moved locations... Basically the filter looks at the referrer, and if it's the local server, it looks at the requested URL and compared it to the full referrer. If the first path is identical, nothing is done, however if not, it takes the first path from the full referrer and prepends it to the URL. For example: /Content/imgs/img.jpg from a referrer of http://myserver/wr/apps/default.htm would be rewritten as /wr/Content/imgs/img.jpg. When I view the log file, everything looks good. However the DLL keeps faulting with the following information: Faulting application w3wp.exe, version 6.0.3790.3959, faulting module URLRedirector.dll, version 0.0.0.0, fault address 0x0002df25.

• Reserve RAM in C

  - by petersmith221

  Hi I need ideas on how to write a C program that reserve a specified amount of MB RAM until a key [ex. the any key] is pressed on a Linux 2.6 32 bit system. * /.eat_ram.out 200 # If free -m is execute at this time, it should report 200 MB more in the used section, than before running the program. [Any key is pressed] # Now all the reserved RAM should be released and the program exits. * It is the core functionality of the program [reserving the RAM] i do not know how to do, getting arguments from the commandline, printing [Any key is pressed] and so on is not a problem from me. Any ideas on how to do this?

• How to release MPMoviePlayerController?

  - by 4thSpace

  I have a couple of views that access the movie player. I've put the following code in a method in AppDelegate for these views. They send in the filename to play. The code works fine but I know a release is required somewhere. If I add the last line as a release or autorelease, the app will crash once the user presses done on the movieplayer. MPMoviePlayerController *moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:[NSURL fileURLWithPath:moviePath]]; moviePlayer.movieControlMode = MPMovieControlModeDefault; [moviePlayer play]; //[moviePlayer release]; I get this error: objc[51051]: FREED(id): message videoViewController sent to freed object=0x1069b30 Program received signal: “EXC_BAD_INSTRUCTION”. How should I be releasing the player?

• iPhone crashing when presenting modal view controller

  - by Michael Waterfall

  Hi there, I'm trying to display a modal view straight after another view has been presented modally (the second is a loading view that appears). - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; // Show load LoadViewController *loader = [[LoadViewController alloc] init]; [self presentModalViewController: loader animated:NO]; [loader release]; } But when I do this I get a "Program received signal: "EXC_BAD_ACCESS"." error. The stack trace is: 0 0x30b43234 in -[UIWindowController transitionViewDidComplete:fromView:toView:] 1 0x3095828e in -[UITransitionView notifyDidCompleteTransition:] 2 0x3091af0d in -[UIViewAnimationState sendDelegateAnimationDidStop:finished:] 3 0x3091ad7c in -[UIViewAnimationState animationDidStop:finished:] 4 0x0051e331 in run_animation_callbacks 5 0x0051e109 in CA::timer_callback 6 0x302454a0 in CFRunLoopRunSpecific 7 0x30244628 in CFRunLoopRunInMode 8 0x32044c31 in GSEventRunModal 9 0x32044cf6 in GSEventRun 10 0x309021ee in UIApplicationMain 11 0x00002154 in main at main.m:14 Any ideas? I'm totally stumped! The loading view is empty so there's definitely nothing going on in there that's causing the error. Is it something to do with launching 2 views modally in the same event loop or something? Thanks, Mike Edit: Very strange... I have modified it slightly so that the loading view is shown after a tiny delay, and this works fine! So it appears to be something within the same event loop! - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; // Show load [self performSelector:@selector(doit) withObject:nil afterDelay:0.1]; } - (void)doit { [self presentModalViewController:loader animated:YES]; }

• UIWebView leak? Can someone confirm?

  - by Shaggy Frog

  I was leak-testing my current project and I'm stumped. I've been browsing like crazy and tried everything except chicken sacrifice. I just created a tiny toy project app from scratch and I can duplicate the leak in there. So either UIWebView has a leak or I'm doing something really silly. Essentially, it boils down to a loadRequest: call to a UIWebView object, given an URLRequest built from an NSURL which references a file URL, for a file in the app bundle, which lives inside a folder that Xcode is including by reference. Phew. The leak is intermittent but still happens ~75% of the time (in about 20 tests it happened about 15 times). It only happens on the device -- this does not leak in the simulator. I am testing targeting both iPhone OS 3.1.2 and 3.1.3, on an original (1st Gen) iPod Touch that is using iPhone OS 3.1.3. To reproduce, just create a project from scratch. Add a UIWebView to the RootViewController's .xib, hook it up via IBOutlet. In the Finder, create a folder named "html" inside your project's folder. Inside that folder, create a file named "dummy.html" that has the word "Test" in it. (Does not need to be valid HTML.) Then add the html folder to your project in Xcode by choosing "Create Folder References for any added folders" Add the following to viewDidLoad NSString* resourcePath = [[NSBundle mainBundle] resourcePath]; NSString* filePath = [[resourcePath stringByAppendingPathComponent:@"html"] stringByAppendingPathComponent:@"dummy.html"]; NSURL* url = [[NSURL alloc] initFileURLWithPath:filePath]; NSURLRequest* request = [NSURLRequest requestWithURL:url]; // <-- this creates the leak! [browserView loadRequest:request]; [url release]; I've tried everything from setting delegate for the UIWebView and implementing UIWebViewDelegate, to not setting a delegate in IB, to not setting a delegate in IB and explicitly setting the web view's delegate property to nil, to using alloc/init instead of getting autoreleased NSURLRequests (and/or NSURLs)... I tried the answer to a similar question (setting the shared URL cache to empty) and that did not help. Can anyone help?

• What’s the Minimum System Spec Recommended For Developer Laptop

  - by DaveDev

  I'll be regularly running Visual Studio 2010 Professional, SQLServer Express, Office and at least 1 virtual environment running a Linux Distro. I want the machine to be snappy and responsive even when doing a reasonable amount of Development work. I want to spend what it takes for this, but I don't want to go overboard spending more than I need to. I won't be playing many games or graphics processing so i won't need a monster of a machine. Any recommendations?

• java.lang.Error: "Not enough storage is available to process this command" when generating images

  - by jhericks

  I am running a web application on BEA Weblogic 9.2. Until recently, we were using JDK 1.5.0_04, with JAI 1.1.2_01 and Image IO 1.1. In some circumstances (we never figured out exactly why), when we were processing large images (but not that large - a few MB), the JVM would crash without any error message or stack trace or anything. This didn't happen much in production, but enough to be a nuisance and eventually we were able to reproduce it. We decided to switch to JRockit90 1.5.0_04 and we were no longer able to reproduce the problem in our test environment, so we thought we had it licked. Now, however, after the application server has been up for a while, we start getting the error message, "Not enough storage is available to process this command" during image operations. For example: java.lang.Error: Error starting thread: Not enough storage is available to process this command. at java.lang.Thread.start()V(Unknown Source) at sun.awt.image.ImageFetcher$1.run(ImageFetcher.java:279) at sun.awt.image.ImageFetcher.createFetchers(ImageFetcher.java:272) at sun.awt.image.ImageFetcher.add(ImageFetcher.java:55) at sun.awt.image.InputStreamImageSource.startProduction(InputStreamImageSource.java:149) at sun.awt.image.InputStreamImageSource.addConsumer(InputStreamImageSource.java:106) at sun.awt.image.InputStreamImageSource.startProduction(InputStreamImageSource.java:144) at sun.awt.image.ImageRepresentation.startProduction(ImageRepresentation.java:647) at sun.awt.image.ImageRepresentation.prepare(ImageRepresentation.java:684) at sun.awt.SunToolkit.prepareImage(SunToolkit.java:734) at java.awt.Component.prepareImage(Component.java:3073) at java.awt.ImageMediaEntry.startLoad(MediaTracker.java:906) at java.awt.MediaEntry.getStatus(MediaTracker.java:851) at java.awt.ImageMediaEntry.getStatus(MediaTracker.java:902) at java.awt.MediaTracker.statusAll(MediaTracker.java:454) at java.awt.MediaTracker.waitForAll(MediaTracker.java:405) at java.awt.MediaTracker.waitForAll(MediaTracker.java:375) at SfxNET.System.Drawing.ImageLoader.loadImage(Ljava.awt.Image;)Ljava.awt.image.BufferedImage;(Unknown Source) at SfxNET.System.Drawing.ImageLoader.loadImage(Ljava.net.URL;)Ljava.awt.image.BufferedImage;(Unknown Source) at Resources.Tools.Commands.W$zw(Ljava.lang.ClassLoader;)V(Unknown Source) at Resources.Tools.Commands.getContents()[[Ljava.lang.Object;(Unknown Source) at SfxNET.sfxUtils.SfxResourceBundle.handleGetObject(Ljava.lang.String;)Ljava.lang.Object;(Unknown Source) at java.util.ResourceBundle.getObject(ResourceBundle.java:320) at SoftwareFX.internal.ChartFX.wxvw.yxWW(Ljava.lang.String;Z)Ljava.lang.Object;(Unknown Source) at SoftwareFX.internal.ChartFX.wxvw.vxWW(Ljava.lang.String;)Ljava.lang.Object;(Unknown Source) at SoftwareFX.internal.ChartFX.CommandBar.YWww(LSoftwareFX.internal.ChartFX.wxvw;IIII)V(Unknown Source) at SoftwareFX.internal.ChartFX.Internet.Server.xxvw.YzzW(LSoftwareFX.internal.ChartFX.Internet.Server.ChartCore;Z)LSoftwareFX.internal.ChartFX.CommandBar;(Unknown Source) at SoftwareFX.internal.ChartFX.Internet.Server.xxvw.XzzW(LSoftwareFX.internal.ChartFX.Internet.Server.ChartCore;)V(Unknown Source) at SoftwareFX.internal.ChartFX.Internet.Server.ChartCore.OnDeserialization(Ljava.lang.Object;)V(Unknown Source) at SoftwareFX.internal.ChartFX.Internet.Server.ChartCore.Zvvz(LSoftwareFX.internal.ChartFX.Base.wzzy;)V(Unknown Source) Has anyone seen something like this before?

• UIView drawRect; class variables out of scope

  - by Toby Wilson

  Short & sweet version of my last question in light of new information. I have a UIVIew with an init and a drawrect method (and another thread and a bunch of other stuff, but I'll keep it short & sweet). All of the class variables that I alloc and init in the -(id)init method are out of scope/nil/0x0 in the drawRect method, and I am unable to access them. For example; In the interface: NSObject* fred; In the implementation: -(id)init { if(self == [super init]) { fred = [[NSObject alloc] init]; } return self; } -(void)drawRect:(CGRect)rect { NSLog(@"Fred is retained %i times",[fred retainCount]); //FAIL NSLog(@"But his variable is actually just pointing at uninitialised 0x0, so you're not reading this in the debugger because the application has crashed before it got here." } Should add that init IS being called before drawRect also. Anyone have any ideas?

• Do I need getters and setters if i'm depending on garbage collection in objective-c

  - by Chris

  New to Cocoa and Objective-c. Do I need getters and setters if I'm depending on garbage collection? For example is it safe to just modify instance variables directly without the dot syntax? And in the dealloc method can I sent them to nil instead of release (or do I even have to release them)?
