  • The CLR has been unable to transition from COM context [...] for 60 seconds

    - by BlueRaja The Green Unicorn
    I am getting this error on code that used to work. I have not changed the code. Here is the full error: The CLR has been unable to transition from COM context 0x3322d98 to COM context 0x3322f08 for 60 seconds. The thread that owns the destination context/apartment is most likely either doing a non pumping wait or processing a very long running operation without pumping Windows messages. This situation generally has a negative performance impact and may even lead to the application becoming non responsive or memory usage accumulating continually over time. To avoid this problem, all single threaded apartment (STA) threads should use pumping wait primitives (such as CoWaitForMultipleHandles) and routinely pump messages during long running operations. And here is the code that caused it: var openFileDialog1 = new System.Windows.Forms.OpenFileDialog(); openFileDialog1.DefaultExt = "mdb"; openFileDialog1.Filter = "Management Database (manage.mdb)|manage.mdb"; //Stalls indefinitely on the following line, then gives the CLR error //one minute later. The dialog never opens. if(openFileDialog1.ShowDialog() == DialogResult.OK) { .... } Yes, I am sure the dialog is not open in the background, and no, I don't have any explicit COM code or unmanaged marshalling or multithreading. I have no idea why the OpenFileDialog won't open - any ideas?

  • In Ruby, why does a method invocation not be able to be treated as a unit when "do" and "end" is use

    - by Jian Lin
    The following question is related to http://stackoverflow.com/questions/2127836/ruby-print-inject-do-syntax The question is, can we insist on using DO and END and make it work with puts or p? This works: a = [1,2,3,4] b = a.inject do |sum, x| sum + x end puts b # prints out 10 so, is it correct to say, inject is a class method of the Array class, which takes a block of code, and then returns a number. If so, then it should be no different from calling a function and getting back a return value: b = foo(3) puts b or b = circle.getRadius() puts b In the above two cases, we can directly say puts foo(3) puts circle.getRadius() so, there is no way to make it work directly by using the following 2 ways: a = [1,2,3,4] puts a.inject do |sum, x| sum + x end but it gives ch01q2.rb:7:in `inject': no block given (LocalJumpError) from ch01q2.rb:4:in `each' from ch01q2.rb:4:in `inject' from ch01q2.rb:4 grouping the method call using ( ) doesn't work either: a = [1,2,3,4] puts (a.inject do |sum, x| sum + x end) and this gives: ch01q3.rb:4: syntax error, unexpected kDO_BLOCK, expecting ')' puts (a.inject do |sum, x| ^ ch01q3.rb:4: syntax error, unexpected '|', expecting '=' puts (a.inject do |sum, x| ^ ch01q3.rb:6: syntax error, unexpected kEND, expecting $end end) ^ finally, the following version works: a = [1,2,3,4] puts a.inject { |sum, x| sum + x } but why doesn't the grouping of the method invocation using ( ) work? What if a programmer insists that he uses do and end, can it be made to work directly with p or puts, without an extra temporary variable?

    Hello guys. I had a server crash several days ago. I use Cacti to keep stats: at the time when the server crashed, a huge spike from Load 1 to Load 200 occurred, with over 800 processes in the run queue ( from 300 average).

  • Why is my Scala function returning type Unit and not whatever is the last line?

    - by Andy
    I am trying to figure out the issue, and tried different styles that I have read on Scala, but none of them work. My code is: .... val str = "(and x y)"; def stringParse ( exp: String, pos: Int, expreshHolder: ArrayBuffer[String], follow: Int ) var b = pos; //position of where in the expression String I am currently in val temp = expreshHolder; //holder of expressions without parens var arrayCounter = follow; //just counts to make sure an empty spot in the array is there to put in the strings if(exp(b) == '(') { b = b + 1; while(exp(b) == ' '){b = b + 1} //point of this is to just skip any spaces between paren and start of expression type if(exp(b) == 'a') { temp(arrayCounter) = exp(b).toString; b = b+1; temp(arrayCounter)+exp(b).toString; b = b+1; temp(arrayCounter) + exp(b).toString; arrayCounter+=1} temp; } } val hold: ArrayBuffer[String] = stringParse(str, 0, new ArrayBuffer[String], 0); for(test <- hold) println(test); My error is: Driver.scala:35: error: type mismatch; found : Unit required: scala.collection.mutable.ArrayBuffer[String] ho = stringParse(str, 0, ho, 0); ^one error found When I add an equals sign after the arguments in the method declaration, like so: def stringParse ( exp: String, pos: Int, expreshHolder: ArrayBuffer[String], follow: Int ) ={....} It changes it to "Any". I am confused on how this works. Any ideas? Much appreciated.

  • Optimal storage of data structure for fast lookup and persistence

    - by Mikael Svenson
    Scenario I have the following methods: public void AddItemSecurity(int itemId, int[] userIds) public int[] GetValidItemIds(int userId) Initially I'm thinking storage on the form: itemId -> userId, userId, userId and userId -> itemId, itemId, itemId AddItemSecurity is based on how I get data from a third party API, GetValidItemIds is how I want to use it at runtime. There are potentially 2000 users and 10 million items. Item id's are on the form: 2007123456, 2010001234 (10 digits where first four represent the year). AddItemSecurity does not have to perform super fast, but GetValidIds needs to be subsecond. Also, if there is an update on an existing itemId I need to remove that itemId for users no longer in the list. I'm trying to think about how I should store this in an optimal fashion. Preferably on disk (with caching), but I want the code maintainable and clean. If the item id's had started at 0, I thought about creating a byte array the length of MaxItemId / 8 for each user, and set a true/false bit if the item was present or not. That would limit the array length to little over 1mb per user and give fast lookups as well as an easy way to update the list per user. By persisting this as Memory Mapped Files with the .Net 4 framework I think I would get decent caching as well (if the machine has enough RAM) without implementing caching logic myself. Parsing the id, stripping out the year, and store an array per year could be a solution. The ItemId - UserId[] list can be serialized directly to disk and read/write with a normal FileStream in order to persist the list and diff it when there are changes. Each time a new user is added all the lists have to updated as well, but this can be done nightly. Question Should I continue to try out this approach, or are there other paths which should be explored as well? I'm thinking SQL server will not perform fast enough, and it would give an overhead (at least if it's hosted on a different server), but my assumptions might be wrong. Any thought or insights on the matter is appreciated. And I want to try to solve it without adding too much hardware :) [Update 2010-03-31] I have now tested with SQL server 2008 under the following conditions. Table with two columns (userid,itemid) both are Int Clustered index on the two columns Added ~800.000 items for 180 users - Total of 144 million rows Allocated 4gb ram for SQL server Dual Core 2.66ghz laptop SSD disk Use a SqlDataReader to read all itemid's into a List Loop over all users If I run one thread it averages on 0.2 seconds. When I add a second thread it goes up to 0.4 seconds, which is still ok. From there on the results are decreasing. Adding a third thread brings alot of the queries up to 2 seonds. A forth thread, up to 4 seconds, a fifth spikes some of the queries up to 50 seconds. The CPU is roofing while this is going on, even on one thread. My test app takes some due to the speedy loop, and sql the rest. Which leads me to the conclusion that it won't scale very well. At least not on my tested hardware. Are there ways to optimize the database, say storing an array of int's per user instead of one record per item. But this makes it harder to remove items.

  • Linked List exercise, what am I doing wrong?

  • [NSCustomView isOpaque]: message sent to deallocated instance 0x123456

    - by JxXx
    Hi all I receive that message in debugger console since I added the following arguments for debugging my application with XCode. NSZombieEnabled: YES NSZombieLevel: 16 I was looking for zombie objects... Before doing so, the application failed before I could know where what and why was happening.... Now I´m pretty sure that 'something' outside code is trying to access an object previously released and I can't know where or why it happens neither where it was released... My application is based on this proof of concept (very interesting and colorful) of QuartzCore Framework: http://www.cimgf.com/2008/03/03/core-animation-tutorial-wizard-dialog-with-transitions/ Based on it, I added a few more nsviews to my project and a title and an index to each one, also I added some buttons, text and images depending on what 'dialog' (ACLinkedView object) it was... The transition from an ACLinkedView object to another is going through a validation that depends on the view where you are ... As you see I used this proof of concept as the foundation of my application and it grew and grew into an application that makes use of configuration files, web services (using gSOAP and C ...) I hope you can give me some clues to where is my error ... I´ve been the hole week debugging unsuccessfully, as I said before, I think that that message comes from a point outside my code. I'd say that the problem s related with bad memory allocation or automatisms (nearly completely unknowns for me) during loading the nib components... I will try to explain all this with parts of mycode. This is my ACLinkedView definition: #import <Cocoa/Cocoa.h> @interface ACLinkedView : NSView { // The Window (to close it if needed) IBOutlet NSWindow *mainWindow; // Linked Views IBOutlet ACLinkedView *previousView; IBOutlet ACLinkedView *nextView; // Buttons IBOutlet NSButton *previousButton; IBOutlet NSButton *nextButton; IBOutlet NSButton *helpButton; //It has to be a Button!! IBOutlet NSImageView *bannerImg; NSString *sName; int iPosition; } - (void) SetName: (NSString*) Name; - (void) SetPosition: (int) Position; - (NSString*) GetName; - (int) GetPosition; - (void) windowWillClose:(NSNotification*)aNotification; @property (retain) NSWindow *mainWindow; @property (retain) ACLinkedView *previousView, *nextView; @property (retain) NSButton *previousButton, *nextButton, *helpButton; @property (retain) NSImageView *bannerImg; @property (retain) NSString *sName; @end The ACLinkedView's AwakeFromNib is this: #import <Cocoa/Cocoa.h> @interface ACLinkedView : NSView { // The Window (to close it if needed) IBOutlet NSWindow *mainWindow; // Linked Views IBOutlet ACLinkedView *previousView; IBOutlet ACLinkedView *nextView; // Buttons IBOutlet NSButton *previousButton; IBOutlet NSButton *nextButton; IBOutlet NSButton *helpButton; //It has to be a Button!!

  • My server app works strangely. What could be the reason(s)?

    - by Poni
    Hi! I've written a server app (two parts actually; proxy server and a game server) using C++ (board game). It uses IOCP as the sockets interface. For that app I've also written a "client simulator" (hereafter "client") app that spawns many client connections, where each of them plays, in very high speed, getting the CPU to be 100% utilized. So, that's how it goes in terms of topology: Game server - holds the game state. Real players do not connect it directly but through the proxy server. When a player joins a game, the proxy actually asks for it on behalf of that player, and the game server spawns a "player instance" for that player, and from now on, every notification between the game server and the player is being passed through the proxy. Proxy server - holds TCP connections with the real players. Players communicate with the game server through it only. Client simulator - connects to the proxy only. When running the server (again, it's actually two server apps) & client locally it all works just fine. I'm talking about 40k+ player instances in which all of them are active in a game. On the other hand, when running the server remotely with, say, 1000 clients who play things getting strange. For example, I run it as said above. Then with Task Manager I kill the client simulator app ("End Process Tree"). Then it seems like the buffer of the remote server got modified by another thread, or in other words, a memory corruption has been occurred. The server crashes because it got an unknown message id (it's a custom protocol where each message has it's own unique number). To make things clear, here is how I run the apps: PC1 - game server and clients simulator (because the clients will connect the proxy). PC2 - proxy server. The strangest thing is this: Only the remote side gets "corrupted". Remote in terms that it's not the PC I use to code the app (VC++ 2008). Let's call the PC I use to code the apps "PC1". Now for example, if this time I ran the game server on PC1 (it means that proxy server on PC2 and clients simulator on PC1), then the proxy server crashes with an "unknown message id" error. Another variation is when I run the proxy server on PC1 (again, the dev machine), the game server and the clients simulator on PC2, then the game server on PC2 gets crashed. As for the IOCP config: The servers' internal connections use the default receive/send buffer sizes. Tried even with setting them to 1MB, but no luck. I have three PCs in total; 2 x Vista 64bit <<-- one of those is the dev machine. The other is connected through WiFi. 1 x WinXP 32bit They're all connected in a "full duplex" manner. What could be the reason? Tried about everything; Stack tracing, recording some actions (like read/write logging).. I want to stress that only the PC I'm not using to code the apps crashes (actually the server app "role" which is running on it - sometimes the game server and sometimes the proxy server). At first I thought that maybe the wireless PC has problems (it's wireless..) but: TCP has it's own mechanisms to make sure the packet is delivered properly. Also, a crash also happens when trying it with the two PCs that are physically connected (Vista vs. XP). Another option is that the Windows DLLs versions might have problems, but then again, one of the tests is Vista vs. Vista, and the other is Vista vs. XP. Any idea?

  • [C] Texture management / pointer question

    - by ndg
    I'm working on a texture management and animation solution for a small side project of mine. Although the project uses Allegro for rendering and input, my question mostly revolves around C and memory management. I wanted to post it here to get thoughts and insight into the approach, as I'm terrible when it comes to pointers. Essentially what I'm trying to do is load all of my texture resources into a central manager (textureManager) - which is essentially an array of structs containing ALLEGRO_BITMAP objects. The textures stored within the textureManager are mostly full sprite sheets. From there, I have an anim(ation) struct, which contains animation-specific information (along with a pointer to the corresponding texture within the textureManager). To give you an idea, here's how I setup and play the players 'walk' animation: createAnimation(&player.animations[0], "media/characters/player/walk.png", player.w, player.h); playAnimation(&player.animations[0], 10); Rendering the animations current frame is just a case of blitting a specific region of the sprite sheet stored in textureManager. For reference, here's the code for anim.h and anim.c. I'm sure what I'm doing here is probably a terrible approach for a number of reasons. I'd like to hear about them! Am I opening myself to any pitfalls? Will this work as I'm hoping? anim.h #ifndef ANIM_H #define ANIM_H #define ANIM_MAX_FRAMES 10 #define MAX_TEXTURES 50 struct texture { bool active; ALLEGRO_BITMAP *bmp; }; struct texture textureManager[MAX_TEXTURES]; typedef struct tAnim { ALLEGRO_BITMAP **sprite; int w, h; int curFrame, numFrames, frameCount; float delay; } anim; void setupTextureManager(void); int addTexture(char *filename); int createAnimation(anim *a, char *filename, int w, int h); void playAnimation(anim *a, float delay); void updateAnimation(anim *a); #endif anim.c void setupTextureManager() { int i = 0; for(i = 0; i < MAX_TEXTURES; i++) { textureManager[i].active = false; } } int addTextureToManager(char *filename) { int i = 0; for(i = 0; i < MAX_TEXTURES; i++) { if(!textureManager[i].active) { textureManager[i].bmp = al_load_bitmap(filename); textureManager[i].active = true; if(!textureManager[i].bmp) { printf("Error loading texture: %s", filename); return -1; } return i; } } return -1; } int createAnimation(anim *a, char *filename, int w, int h) { int textureId = addTextureToManager(filename); if(textureId > -1) { a->sprite = textureManager[textureId].bmp; a->w = w; a->h = h; a->numFrames = al_get_bitmap_width(a->sprite) / w; printf("Animation loaded with %i frames, given resource id: %i\n", a->numFrames, textureId); } else { printf("Texture manager full\n"); return 1; } return 0; } void playAnimation(anim *a, float delay) { a->curFrame = 0; a->frameCount = 0; a->delay = delay; } void updateAnimation(anim *a) { a->frameCount ++; if(a->frameCount >= a->delay) { a->frameCount = 0; a->curFrame ++; if(a->curFrame >= a->numFrames) { a->curFrame = 0; } } }

  • Is there a potential for resource leak/double free here?

    - by nhed
    The following sample (not compiled so I won't vouch for syntax) pulls two resources from resource pools (not allocated with new), then "binds" them together with MyClass for the duration of a certain transaction. The transaction, implemented here by myFunc, attempts to protect against leakage of these resources by tracking their "ownership". The local resource pointers are cleared when its obvious that instantiation of MyClass was successful. The local catch, as well as the destructor ~MyClass return the resources to their pool (double-frees are protected by teh above mentioned clearing of the local pointers). Instantiation of MyClass can fail and result in an exception at two steps (1) actual memory allocation, or (2) at the constructor body itself. I do not have a problem with #1, but in the case of #2, if the exception is thrown AFTER m_resA & m_resB were set. Causing both the ~MyClass and the cleanup code of myFunc to assume responsibility for returning these resources to their pools. Is this a reasonable concern? Options I have considered, but didn't like: Smart pointers (like boost's shared_ptr). I didn't see how to apply to a resource pool (aside for wrapping in yet another instance). Allowing double-free to occur at this level but protecting at the resource pools. Trying to use the exception type - trying to deduce that if bad_alloc was caught that MyClass did not take ownership. This will require a try-catch in the constructor to make sure that any allocation failures in ABC() ...more code here... wont be confused with failures to allocate MyClass. Is there a clean, simple solution that I have overlooked? class SomeExtResourceA; class SomeExtResourceB; class MyClass { private: // These resources come out of a resource pool not allocated with "new" for each use by MyClass SomeResourceA* m_resA; SomeResourceB* m_resB; public: MyClass(SomeResourceA* resA, SomeResourceB* resB): m_resA(resA), m_resB(resB) { ABC(); // ... more code here, could throw exceptions } ~MyClass(){ if(m_resA){ m_resA->Release(); } if(m_resB){ m_resB->Release(); } } }; void myFunc(void) { SomeResourceA* resA = NULL; SomeResourceB* resB = NULL; MyClass* pMyInst = NULL; try { resA = g_pPoolA->Allocate(); resB = g_pPoolB->Allocate(); pMyInst = new MyClass(resA,resB); resA=NULL; // ''ownership succesfully transfered to pMyInst resB=NULL; // ''ownership succesfully transfered to pMyInst // Do some work with pMyInst; ...; delete pMyInst; } catch (...) { // cleanup // need to check if resA, or resB were allocated prior // to construction of pMyInst. if(resA) resA->Release(); if(resB) resB->Release(); delete pMyInst; throw; // rethrow caught exception } }

  • 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). The requests themselves are very lightweight, not more than looking for an entity or saving it, using DataMapper. On appspot, this problem is not happening. Is there any way to enlarge the heap space for JRuby? The exception log: Exception in thread "Timer-2" java.lang.OutOfMemoryError: Java heap space Apr 29, 2010 8:08:22 AM com.google.apphosting.utils.jetty.JettyLogger warn WARNING: Error for /users/close_users java.lang.OutOfMemoryError: Java heap space at org.jruby.RubyHash.internalPut(RubyHash.java:480) at org.jruby.RubyHash.internalPut(RubyHash.java:461) at org.jruby.RubyHash.fastASet(RubyHash.java:837) at org.jruby.RubyArray.makeHash(RubyArray.java:2998) at org.jruby.RubyArray.makeHash(RubyArray.java:2992) at org.jruby.RubyArray.op_diff(RubyArray.java:3103) at org.jruby.RubyArray$i_method_1_0$RUBYINVOKER$op_diff.call(org/jruby/RubyArray$i_method_1_0$RUBYINVOKER$op_diff.gen) at org.jruby.runtime.callsite.CachingCallSite.call(CachingCallSite.java:146) at org.jruby.ast.CallOneArgNode.interpret(CallOneArgNode.java:57) at org.jruby.ast.LocalAsgnNode.interpret(LocalAsgnNode.java:123) at org.jruby.ast.NewlineNode.interpret(NewlineNode.java:104) at org.jruby.ast.BlockNode.interpret(BlockNode.java:71) at org.jruby.runtime.InterpretedBlock.evalBlockBody(InterpretedBlock.java:373) at org.jruby.runtime.InterpretedBlock.yield(InterpretedBlock.java:346) at org.jruby.runtime.InterpretedBlock.yield(InterpretedBlock.java:303) at org.jruby.runtime.Block.yield(Block.java:194) at org.jruby.RubyArray.collect(RubyArray.java:2354) at org.jruby.RubyArray$i_method_0_0$RUBYFRAMEDINVOKER$collect.call(org/jruby/RubyArray$i_method_0_0$RUBYFRAMEDINVOKER$collect.gen) at org.jruby.runtime.callsite.CachingCallSite.callBlock(CachingCallSite.java:115) at org.jruby.runtime.callsite.CachingCallSite.call(CachingCallSite.java:122) at org.jruby.ast.CallNoArgBlockNode.interpret(CallNoArgBlockNode.java:64) at org.jruby.ast.CallNoArgNode.interpret(CallNoArgNode.java:61) at org.jruby.ast.LocalAsgnNode.interpret(LocalAsgnNode.java:123) at org.jruby.ast.NewlineNode.interpret(NewlineNode.java:104) at org.jruby.ast.BlockNode.interpret(BlockNode.java:71) at org.jruby.ast.EnsureNode.interpret(EnsureNode.java:98) at org.jruby.ast.BeginNode.interpret(BeginNode.java:83) at org.jruby.ast.NewlineNode.interpret(NewlineNode.java:104) at org.jruby.ast.BlockNode.interpret(BlockNode.java:71) at org.jruby.ast.EnsureNode.interpret(EnsureNode.java:96) at org.jruby.internal.runtime.methods.InterpretedMethod.call(InterpretedMethod.java:201) at org.jruby.internal.runtime.methods.DefaultMethod.call(DefaultMethod.java:183)

  • Validation Summary for Lists using Data Annotations with MVC

    - by David Liddle
    I currently use a custom method to display validation error messages for lists but would like to replace this system for using with Data Annotations. In summary on validation of my form, I want to display "*" next to each input that is incorrect and also provide a Validation Summary at the bottom that relates each error message to the particular item in the list. e.g. say if validation failed on the 2nd list item on a Name input box and the 4th item on an Address input box the validation summary would display [2] Name is invalid [4] Address is invalid Please ignore if there are mistakes in the code below. I'm just writing this as an example. The code below shows how I was able to do it using my custom version of adding model errors but was wondering how to do this using Data Annotations? //Domain Object public class MyObject { public int ID { get; set; } public string Name { get; set; } public string Address { get; set; } public bool IsValid { get { return (GetRuleViolations().Count() == 0); } } public void IEnumerable<RuleViolation> GetRuleViolations() { if (String.IsNullOrEmpty(Name)) yield return new RuleViolation(ID, "Name", "Name is invalid"); if (String.IsNullOrEmpty(Address)) yield return new RuleViolation(ID, "Address", "Address is invalid"); yield break; } } //Rule Violation public class RuleViolation { public int ID { get; private set; } public string PropertyName { get; private set; } public string ErrorMessage { get; private set; } } //View <% for (int i = 0; i < 5; i++) { %> <p> <%= Html.Hidden("myObjects[" + i + "].ID", i) %> Name: <%= Html.TextBox("myObjects[" + i + "].Name") %> <br /> <%= Html.ValidationMessage("myObjects[" + i + "].Name", "*")<br /> Address: <%= Html.TextBox("myObjects[" + i + "].Address") %> <%= Html.ValidationMessage("myObjects[" + i + "].Address", "*")<br /> </p> <% } %> <p><%= Html.ValidationSummary() %> //Controller public ActionResult MyAction(IList<MyObject> myObjects) { foreach (MyObject o in myObjects) { if (!o.IsValid) ModelState.AddModelErrors(o.GetRuleViolations(), o.GetType().Name); } if (!Model.IsValid) { return View(); } } public static class ModelStateExtensions { public static void AddModelError(this ModelStateDictionary modelState, RuleViolation issue, string name) { string key = String.Format("{0}[{1}].{2}", name, issue.ID, issue.PropertyName); string error = String.Format("[{0}] {1}", (issue.ID + 1), issue.ErrorMessage); //above line determines the [ID] ErrorMessage to be //displayed in the Validation Summary modelState.AddModelError(key, error); }

  • Objective-C object release and allocation timing

    - by ryanjm.mp
    The code for this question is too long to be of any use. But I'm pretty sure my problem has to do with releasing a class. I have a helper class, ConnectionHelper.h/.m, that handles a NSURLConnection for me. Basically, I give it the URL I want and it returns the data (it happens to do a quick json parse on it too). It has a delegate which I set to the calling class (in this case: DownloadViewController). When it finishes the download, it calls [delegate didFinishParseOf:objectName withDictionary:dictionary];. Then in DownloadViewController I release ConnectionHelper and alloc a new one in order to download the next object. My problem is, I do this once, and then it creates the connection for the second one, and then my program just crashes. After this call: [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyNever]; NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; Then I don't think any of the following methods are called: - (NSCachedURLResponse *)connection:(NSURLConnection *)connection willCacheResponse:(NSCachedURLResponse *)cachedResponse - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error - (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge So am I right in that I'm not releasing something? When I release it the first time, the dealloc function isn't being called. Is there a way I can "force" it to deallocate? Do I need to force it to? I didn't think it would matter since I allocating a new ConnectionHelper for the new call. How else would they overlap / conflict with each other? Thank you.

  • Java: Reading images and displaying as an ImageIcon

    - by 11helen
    I'm writing an application which reads and displays images as ImageIcons (within a JLabel), the application needs to be able to support jpegs and bitmaps. For jpegs I find that passing the filename directly to the ImageIcon constructor works fine (even for displaying two large jpegs), however if I use ImageIO.read to get the image and then pass the image to the ImageIcon constructor, I get an OutOfMemoryError( Java Heap Space ) when the second image is read (using the same images as before). For bitmaps, if I try to read by passing the filename to ImageIcon, nothing is displayed, however by reading the image with ImageIO.read and then using this image in the ImageIcon constructor works fine. I understand from reading other forum posts that the reason that the two methods don't work the same for the different formats is down to java's compatability issues with bitmaps, however is there a way around my problem so that I can use the same method for both bitmaps and jpegs without an OutOfMemoryError? (I would like to avoid having to increase the heap size if possible!) The OutOfMemoryError is triggered by this line: img = getFileContentsAsImage(file); and the method definition is: public static BufferedImage getFileContentsAsImage(File file) throws FileNotFoundException { BufferedImage img = null; try { ImageIO.setUseCache(false); img = ImageIO.read(file); img.flush(); } catch (IOException ex) { //log error } return img; } The stack trace is: Exception in thread "AWT-EventQueue-0" java.lang.OutOfMemoryError: Java heap space at java.awt.image.DataBufferByte.<init>(DataBufferByte.java:58) at java.awt.image.ComponentSampleModel.createDataBuffer(ComponentSampleModel.java:397) at java.awt.image.Raster.createWritableRaster(Raster.java:938) at javax.imageio.ImageTypeSpecifier.createBufferedImage(ImageTypeSpecifier.java:1056) at javax.imageio.ImageReader.getDestination(ImageReader.java:2879) at com.sun.imageio.plugins.jpeg.JPEGImageReader.readInternal(JPEGImageReader.java:925) at com.sun.imageio.plugins.jpeg.JPEGImageReader.read(JPEGImageReader.java:897) at javax.imageio.ImageIO.read(ImageIO.java:1422) at javax.imageio.ImageIO.read(ImageIO.java:1282) at framework.FileUtils.getFileContentsAsImage(FileUtils.java:33)

  • NSMutableArray accessing issue.

    - by Danegraphics
    I've searched and have no answer. I've created an NSMutableArray and am getting an EXC_BAD_ACCESS error in one place of access. Here. This is declaring in the .h file: NSMutableArray *buttons; ... @property (nonatomic, retain)NSMutableArray *buttons; And this is the synthesizing and implimenting: @synthesize buttons; ... - (id)init { self = [super init]; if(self != nil) { buttons = [[NSMutableArray alloc] init]; } return self; } ... -(void)addButtonWithImage:(Image*)image { Image *button = image; [buttons addObject:button]; [button release]; } ... -(void)replaceButtonAt:(int)num with:(Image*)image { Image *button = image; [buttons replaceObjectAtIndex:num withObject:button]; <<===EXC_BAD_ACCESS [button release]; } But when I use this: -(void)renderButton:(int)num atPoint:(CGPoint)point center:(BOOL)center{ Image *button = [buttons objectAtIndex:num]; [button renderAtPoint:point centerOfImage:center]; } It works

  • How to fix "BASIC runtime error 1; Type: com.sun.star.uno.Runtime Exception, Message: Toolbar do not exist " error in Libreoffice calc, Ubuntu 12.04

    - by PDeb
    I get the following error while openning a .xls file in Libreoffice Calc, Ubuntu 12.04 [LibreOffice 3.5.5.2; Build ID: 350m 1 (Build:2)] To overcome this I checked the LibreOffice Security Level to Low under Macro Security (from Tools---- Options--- Security tab. Then I went ahead intalling java by running the following commands from the terminal window (with some tips from various forums) sudo add-apt-repository ppa:libreoffice/ppa sudo apt-get update sudo apt-get install libreoffice libreoffice-java-common libreoffice-math libreoffice-gnome libreoffice-java-common Still I got the BASIC runtime error (as in the title), even after clicking Tools---- Options ---- Java and checking the 'Use a Java runtime environment option' and then clicking on 'Sun Microsystems Inc' under listed JRE environments installed. Even I ran the following commands to install latest Java run time environments from terminal window sudo apt-get install openjdk-7-jre icedtea-7-plugin But still I get the same Basicruntime error (details as in the title bar). This particular file opens perfectly in Microsoft Excel 2007, in Win XP Professional.

  • Failure connecting to Dell MD3200i from XenServer 6.2 pool

    - by Tom Sparrow
    This question also asked at Citrix Forums http://forums.citrix.com/thread.jspa?threadID=332289 I have a MD3200i that is currently working fine with my Xen5.6 pool, but I cannot get a connection to the new 6.2 pool to work. I previously had a problem with a 6.0 upgrade (which is why the old pool is still on 5.6), but rolled back rather than fix it as it wasn't urgent at the time. This install is on new machines - I tried 6.1 first (which had the same problems) then 6.2 was released the second day after installation so I switched to that. I've not installed anything from the Dell resource DVD at this point - I can't find anything saying I should, and everything I have read suggests it shouldn't be necessary. I can ping all 8 ip addresses from both servers in the pool, iscsiadm -m discovery works fine, I can login to the nodes and iscsiadm reports the sessions active correctly. I've added the required sections to multipath.conf, but multipath -ll reports DM multipath kernel driver not loaded immediately after boot. The following is a log of a test session immediately after boot. root@xen3 ~]# iscsiadm -m node --loginall=all Logging in to [iface: default, target:

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

    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?
