  • PCRE multi line matche problem

    - by Simone Margaritelli
    Hi guys, i have this C++ program (actually it's just a snippet) : #include <iostream> #include <pcre.h> #include <string> using namespace std; int main(){ string pattern = "<a\\s+href\\s*=\\s*\"([^\"]+)\"", html = "<html>\n" "<body>\n" "<a href=\"example_link_1\"/>\n" "<a href=\"example_link_2\"/>\n" "<a href=\"example_link_3\"/>\n" "</body>\n" "</html>"; int i, ccount, rc, *offsets, eoffset; const char *error; pcre *compiled; compiled = pcre_compile( pattern.c_str(), PCRE_CASELESS | PCRE_MULTILINE, &error, &eoffset, 0 ); if( !compiled ){ cerr << "Error compiling the regexp!!" << endl; return 0; } rc = pcre_fullinfo( compiled, 0, PCRE_INFO_CAPTURECOUNT, &ccount ); offsets = new int[ 3 * (ccount + 1) ]; rc = pcre_exec( compiled, 0, html.c_str(), html.length(), 0, 0, offsets, 3 * (ccount + 1) ); if( rc >= 0 ){ for( i = 1; i < rc; ++i ){ cout << "Match : " << html.substr( offsets[2*i], offsets[2*i+1] - offsets[2*i] ) << endl; } } else{ cout << "Sorry, no matches!" << endl; } delete [] offsets; return 0; } As you can see, i'm trying to match html links inside a buffer with the given regular expression (the \\s is \s escaped for C/C++ strings). But, even if in the buffer there are 3 links and the regexp is compiled with the PCRE_CASELESS and PCRE_MULTILINE flags, i match only one element : Match : example_link_1 Note: I start the loop fro index 1 because the pcre library returns the string that matched (not the match itself) as the first element, and the matches follows. What's wrong with this code? The regexp itself i think it's correct (tried in PHP for instance).

  • WEBrick::HTTPStatus::LengthRequired error when accessing create method in controller

    - by Chris Bisignani
    I have a very simple controller set up: class LibrariesController < ApplicationController ... def create @user.libraries << Library.new(params) @user.save render :json => "success!" end ... end Basically, whenever I try to access the create method of LibrariesController using HTTParty.post I get a WEBrick::HTTPStatus::LengthRequired error on the server. The method is not even being accessed!

  • ASP.Net MVC Exception Logging combined with Error Handling

    - by Saajid Ismail
    Hi. I am looking for a simple solution to do Exception Logging combined with Error Handling in my ASP.Net MVC 1.0 application. I've read lots of articles, including Questions posted here on StackOverflow, which all provide varying solutions for different situations. I am still unable to come up with a solution that suits my needs. Here are my requirements: To be able to use the [HandleError] attribute (or something equivalent) on my Controller, to handle all exceptions that could be thrown from any of the Actions or Views. This should handle all exceptions that were not handled specifically on any of the Actions (as described in point 2). I would like to be able to specify which View a user must be redirected to in error cases, for all actions in the Controller. I want to be able to specify the [HandleError] attribute (or something equivalent) at the top of specific Actions to catch specific exceptions and redirect users to a View appropriate to the exception. All other exceptions must still be handled by the [HandleError] attribute on the Controller. In both cases above, I want the exceptions to be logged using log4net (or any other logging library). How do I go about achieving the above? I've read about making all my Controllers inherit from a base controller which overrides the OnException method, and wherein I do my logging. However this will mess around with redirecting users to the appropriate Views, or make it messy. I've read about writing my own Filter Action which implements IExceptionFilter to handle this, but this will conflict with the [HandleError] attribute. So far, my thoughts are that the best solution is to write my own attribute that inherits from HandleErrorAttribute. That way I get all the functionality of [HandleError], and can add my own log4net logging. The solution is as follows: public class HandleErrorsAttribute: HandleErrorAttribute { private log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType); public override void OnException(ExceptionContext filterContext) { if (filterContext.Exception != null) { log.Error("Error in Controller", filterContext.Exception); } base.OnException(filterContext); } } Will the above code work for my requirements? If not, what solution does fulfill my requirements?

  • Unity The parameter host could not be resolved when attempting to call constructor

    - by Terrance
    When I attempt to instantiate my instance of the base class I get the error: a ResolutionFailedException with roughly the following error "The parameter host could not be resolved when attempting to call constructor" I'm currently not using an Interface for the base type and my instance of the class is inheriting the base type class. I'm new to Unity and DI so I'm thinking its something I forgot possibly. ExeConfigurationFileMap map = new ExeConfigurationFileMap(); map.ExeConfigFilename = "Unity.Config"; Configuration config = ConfigurationManager.OpenMappedExeConfiguration(map, ConfigurationUserLevel.None); UnityConfigurationSection section = (UnityConfigurationSection)config.GetSection("unity"); IUnityContainer container = new UnityContainer(); section.Containers.Default.Configure(container); //Throws exception here on this BaseCalculatorServer server = container.Resolve<BaseCalculatorServer>(); and the Unity.Config file <container> <types> <type name ="CalculatorServer" type="Calculator.Logic.BaseCalculatorServer, Calculator.Logic" mapTo="Calculator.Logic.CalculateApi, Calculator.Logic"/> </types> </container> </containers> The Base class using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Runtime.Serialization; using System.ServiceModel; using System.ServiceModel.Transactions; using Microsoft.Practices.Unity; using Calculator.Logic; namespace Calculator.Logic { public class BaseCalculatorServer : IDisposable { public BaseCalculatorServer(){} public CalculateDelegate Calculate { get; set; } public CalculationHistoryDelegate CalculationHistory { get; set; } /// <summary> /// Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. /// </summary> public void Dispose() { this.Dispose(); } } } The Implementation using System; using System.Collections.Generic; using System.Linq; using System.Text; using Calculator.Logic; using System.ServiceModel; using System.ServiceModel.Configuration; using Microsoft.Practices.Unity; namespace Calculator.Logic { public class CalculateApi:BaseCalculatorServer { public CalculateApi(ServiceHost host) { host.Open(); Console.WriteLine("Press Enter To Exit"); Console.ReadLine(); host.Close(); } public CalculateDelegate Calculate { get; set; } public CalculationHistoryDelegate CalculationHistory { get; set; } } } Yes both base class and implementation are in the same Namespace and thats something design wise that will change once I get this working. Oh and a more detailed error Resolution of the dependency failed, type = "Calculator.Logic.BaseCalculatorServer", name = "". Exception message is: The current build operation (build key Build Key[Calculator.Logic.BaseCalculatorServer, null]) failed: The value for the property "Calculate" could not be resolved. (Strategy type BuildPlanStrategy, index 3)

  • Safe, standard way to load images in ListView on a different thread?

    - by Po
    Before making this question, I have searched and read these ones: http://stackoverflow.com/questions/541966/android-how-do-i-do-a-lazy-load-of-images-in-listview http://stackoverflow.com/questions/1409623/android-issue-with-lazy-loading-images-into-a-listview My problem is I have a ListView, where: Each row contains an ImageView, whose content is to be loaded from the internet Each row's view is recycled as in ApiDemo's List14 What I want ultimately: Load images lazily, only when the user scrolls to them Load images on different thread(s) to maintain responsiveness My current approach: In the adapter's getView() method, apart from setting up other child views, I launch a new thread that loads the Bitmap from the internet. When that loading thread finishes, it returns the Bitmap to be set on the ImageView (I do this using AsyncTask or Handler). Because I recycle ImageViews, it may be the case that I first want to set a view with Bitmap#1, then later want to set it to Bitmap#2 when the user scrolls down. Bitmap#1 may happen to take longer than Bitmap#2 to load, so it may end up overwriting Bitmap#2 on the view. I solve this by maintaining a WeakHashMap that remembers the last Bitmap I want to set for that view. Below is somewhat a pseudocode for my current approach. I've ommitted other details like caching, just to keep the thing clear. public class ImageLoader { // keeps track of the last Bitmap we want to set for this ImageView private static final WeakHashMap<ImageView, AsyncTask> assignments = new WeakHashMap<ImageView, AsyncTask>(); /** Asynchronously sets an ImageView to some Bitmap loaded from the internet */ public static void setImageAsync(final ImageView imageView, final String imageUrl) { // cancel whatever previous task AsyncTask oldTask = assignments.get(imageView); if (oldTask != null) { oldTask.cancel(true); } // prepare to launch a new task to load this new image AsyncTask<String, Integer, Bitmap> newTask = new AsyncTask<String, Integer, Bitmap>() { protected void onPreExecute() { // set ImageView to some "loading..." image } protected Bitmap doInBackground(String... urls) { return loadFromInternet(imageUrl); } protected void onPostExecute(Bitmap bitmap) { // set Bitmap if successfully loaded, or an "error" image if (bitmap != null) { imageView.setImageBitmap(bitmap); } else { imageView.setImageResource(R.drawable.error); } } }; newTask.execute(); // mark this as the latest Bitmap we want to set for this ImageView assignments.put(imageView, newTask); } /** returns (Bitmap on success | null on error) */ private Bitmap loadFromInternet(String imageUrl) {} } Problem I still have: what if the Activity gets destroyed while some images are still loading? Is there any risk when the loading thread calls back to the ImageView later, when the Activity is already destroyed? Moreover, AsyncTask has some global thread-pool underneath, so if lengthy tasks are not canceled when they're not needed anymore, I may end up wasting time loading things users don't see. My current design of keeping this thing globally is too ugly, and may eventually cause some leaks that are beyond my understanding. Instead of making ImageLoader a singleton like this, I'm thinking of actually creating separate ImageLoader objects for different Activities, then when an Activity gets destroyed, all its AsyncTask will be canceled. Is this too awkward? Anyway, I wonder if there is a safe and standard way of doing this in Android. In addition, I don't know iPhone but is there a similar problem there and do they have a standard way to do this kind of task? Many thanks.

  • Asynchronous readback from opengl front buffer using multiple PBO's

    - by KillianDS
    I am developing an application that needs to read back the whole frame from the front buffer of an openGL application. I can hijack the application's opengl library and insert my code on swapbuffers. At the moment I am successfully using a simple but excruciating slow glReadPixels command without PBO's. Now I read about using multiple PBO's to speed things up. While I think I've found enough resources to actually program that (isn't that hard), I have some operational questions left. I would do something like this: create a series (e.g. 3) of PBO's use glReadPixels in my swapBuffers override to read data from front buffer to a PBO (should be fast and non-blocking, right?) Create a seperate thread to call glMapBufferARB, once per PBO after a glReadPixels, because this will block until the pixels are in client memory. Process the data from step 3. Now my main concern is of course in steps 2 and 3. I read about glReadPixels used on PBO's being non-blocking, will this be an issue if I issue new opengl commands after that very fast? Will those opengl commands block? Or will they continue (my guess), and if so, I guess only swapbuffers can be a problem, will this one stall or will glReadPixels from front buffer be many times faster than swapping (about each 15-30ms) or, worst case scenario, will swapbuffers be executed while glReadPixels is still reading data to the PBO? My current guess is this logic will do something like this: copy FRONT_BUFFER - generic place in VRAM, copy VRAM-RAM. But I have no idea which of those 2 is the real bottleneck and more, what the influence on the normal opengl command stream is. Then in step 3. Is it wise to do this asynchronously in a thread separated from normal opengl logic? At the moment I think not, It seems you have to restore buffer operations to normal after doing this and I can't install synchronization objects in the original code to temporarily block those. So I think my best option is to define a certain swapbuffer delay before reading them out, so e.g. calling glReadPixels on PBO i%3 and glMapBufferARB on PBO (i+2)%3 in the same thread, resulting in a delay of 2 frames. Also, when I call glMapBufferARB to use data in client memory, will this be the bottleneck or will glReadPixels (asynchronously) be the bottleneck? And finally, if you have some better ideas to speed up frame readback from GPU in opengl, please tell me, because this is a painful bottleneck in my current system. I hope my question is clear enough, I know the answer will probably also be somewhere on the internet but I mostly came up with results that used PBO's to keep buffers in video memory and do processing there. I really need to read back the front buffer to RAM and I do not find any clear explanations about performance in that case (which I need, I cannot rely on "it's faster", I need to explain why it's faster). Thank you

  • Why aren't the :locals hash variables being passed in to a partial, when called from inside my rake

    - by marshally
    I need to render a bunch of painfully long running partials using a rake task. When I try to pull the partial from a rake task, I get the dreaded "Called id for nil, which would mistakenly be 4" error, which usually means that my locals hash has not been properly set into the partial. Here's the rake task (some variable names have been changed to protect the innocent): namespace :precache do desc "Precache stuff" task :precache => :environment do av = ActionView::Base.new(Rails::Configuration.new.view_path, {}) av.class_eval do include ApplicationHelper end @user = User.find(21) @rank = Rank.find(2) data = av.render(:partial => "reports/listing", :locals => {:user => @user, :rank => @rank}) end end And this is the error that I am getting: ** Execute precache:precache rake aborted!

  • xamlparser error after clickonce deployment.Application crashing after installation

    Hello Good People, I've built an WPF application with visual studio 2008 and created an installer for it.Works fine so far.I realized it lacks the automatic updates feature, and after trying several solutions, i decided to give a try to clickonce deployment.After a successful deployment on a network server, i 've noticed that the application crashes after installation of the downloaded app.It complains about this: Cannot create instance of 'Login' defined in assembly 'MyApplication, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

Question 1 : Does any one have a similar issue, or is that a known issue? Question 2 : If it's a known issue then what are alternative.I might give up on the clickonce but then i my automatic update feature will be lost (as in there is none which is not ovekill or seriously outdated that i can find right now). thanks for reading this and for pointing me to the right direction.

  • Reproduce PIPE functionality in IronPython

    - by Muppet Geoff
    Hi, I am hoping some genious out there can help me out with this... I am using sox to merge and resample a group of WAV files, and pipe the output directly to the input of NeroAACEnc for encoding to AAC format. I originally ran the process in a script, which included: sox.exe d:\audio\1.wav d:\audio\2.wav d:\audio\3.wav -c 1 -r 22050 -t wav - | neroAacEnc.exe -q 0.5 -if - -of test.m4a This worked as expected. The '-' in the comand line translates as 'Pipe/redirect input/output (stdin/stdout)' - So Sox pipes to stdout, and NeroAACEnc reads from stdin, the | joins them together. I then migrated the whole solution to Python, and the equivalent command became: from subprocess import call, Popen, PIPE runwav = Popen(['sox.exe', 'd:\audio\1.wav', 'd:\audio\2.wav', 'd:\audio\3.wav', '-c', '1', '-r', '22050', '-t', 'wav', '-'], shell=False, stdout=PIPE) runm4b = call(['neroAacEnc.exe', '-q', '0.5', '-if', '-', '-of', 'test.m4a'], shell=False, stdin=runwav.stdout) This also worked like a charm, exactly as expected. Slightly more convoluted, but hey :) Well now I have to move it to IronPython, and the Subprocess module isn't available (the partial implementation that is, doesn't have Popen/PIPE support - plus it seems silly to add a custom library when there is probably a native alternative). I should mention here, that I opted for IronPython over C#, because I am comfortable with Python now - however, there is a chance of moving it again later to C# native, and I am using IronPython to ease myself into it :) I have no C# or .net experience. So far I have the following equivalent, that sets up the 2 processes: from System.Diagnostics import Process wav = Process() wav.StartInfo.UseShellExecute = False wav.StartInfo.RedirectStandardOutput = True wav.StartInfo.FileName = 'sox.exe' wav.StartInfo.Arguments = 'd:\audio\1.wav d:\audio\2.wav d:\audio\3.wav -c 1 -r 22050 -t wav -' wav.Start() m4b = Process() m4b.StartInfo.UseShellExecute = False m4b.StartInfo.RedirectStandardInput = True m4b.StartInfo.FileName = 'neroAacEnc.exe' m4b.StartInfo.Arguments = '-q 0.5 -if - -of test.m4a' m4b.Start() I know that these 2 processes start (I can see Nero and Sox in the task manager) but what I can't figure out (for the life of me) is how to string the two output/input streams together, as with the previous two solutions. I have searched and searched, so I thought I'd ask! If anyone knows either: How to join the two streams with the same net result as the Python and Commandline versions; or A better way to acheive what I am trying to do. I would be extremely grateful! Many thanks in advance, Geoff P.S. A code sample based off the above would be awesome :) or a specific code example of a similar process that I can easily translate... this has broked my brayne.

  • Error in loading component property (Swing GUI Forms)

    - by Christo Du Preez
    For no apparent reason all my Swing GUI forms using components linked to org.jdesktop.beansbinding.Converter started generating errors when trying to open the Design View: Error Error in loading component property: [JPanel]-filterTextField-converter. Cannot load property type class org.jdesktop.beansbinding.Converter. The property cannot be loaded. Errors occurred in loading... I'm currently using Netbeans 6.8. I opened my project in Netbeans 6.7.1 and all was fine but after a while the same thing happened. Looking at the .form and .java files and comparing it to previous backups, everything looks fine. Even my Netbeans tutorial project no longer works. What can cause this. Any suggestions would greatly be appreciated. After further investigation this is taken from my IDE's log : INFO: msg org.openide.ErrorManager$AnnException: msg at org.openide.ErrorManager$AnnException.findOrCreate(ErrorManager.java:867) at org.openide.ErrorManager$DelegatingErrorManager.annotate(ErrorManager.java:650) at org.netbeans.modules.form.GandalfPersistenceManager.annotateException(GandalfPersistenceManager.java:230) at org.netbeans.modules.form.GandalfPersistenceManager.annotateException(GandalfPersistenceManager.java:240) at org.netbeans.modules.form.GandalfPersistenceManager.getPropertyType(GandalfPersistenceManager.java:2362) at org.netbeans.modules.form.GandalfPersistenceManager.loadProperty(GandalfPersistenceManager.java:2041) at org.netbeans.modules.form.GandalfPersistenceManager.loadBindingProperties(GandalfPersistenceManager.java:2627) at org.netbeans.modules.form.GandalfPersistenceManager.loadComponent(GandalfPersistenceManager.java:900) at org.netbeans.modules.form.GandalfPersistenceManager.restoreComponent(GandalfPersistenceManager.java:845) at org.netbeans.modules.form.GandalfPersistenceManager.loadComponent(GandalfPersistenceManager.java:979) at org.netbeans.modules.form.GandalfPersistenceManager.restoreComponent(GandalfPersistenceManager.java:845) at org.netbeans.modules.form.GandalfPersistenceManager.loadNonVisuals(GandalfPersistenceManager.java:695) at org.netbeans.modules.form.GandalfPersistenceManager.loadForm(GandalfPersistenceManager.java:529) at org.netbeans.modules.form.GandalfPersistenceManager.loadForm(GandalfPersistenceManager.java:290) at org.netbeans.modules.form.FormEditor$3.run(FormEditor.java:339) at org.netbeans.modules.form.FormLAF$2.run(FormLAF.java:287) at org.openide.util.Mutex.doEventAccess(Mutex.java:1355) at org.openide.util.Mutex.readAccess(Mutex.java:317) at org.netbeans.modules.form.FormLAF.executeWithLookAndFeel(FormLAF.java:272) at org.netbeans.modules.form.FormEditor.loadFormData(FormEditor.java:337) at org.netbeans.modules.form.FormEditor.loadForm(FormEditor.java:266) at org.netbeans.modules.form.FormEditorSupport.loadForm(FormEditorSupport.java:306) at org.netbeans.modules.form.FormEditorSupport$3.run(FormEditorSupport.java:457) at java.awt.event.InvocationEvent.dispatch(InvocationEvent.java:209) at java.awt.EventQueue.dispatchEvent(EventQueue.java:597) at org.netbeans.core.TimableEventQueue.dispatchEvent(TimableEventQueue.java:125) at java.awt.EventDispatchThread.pumpOneEventForFilters(EventDispatchThread.java:269) at java.awt.EventDispatchThread.pumpEventsForFilter(EventDispatchThread.java:184) at java.awt.EventDispatchThread.pumpEventsForHierarchy(EventDispatchThread.java:174) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:169) at java.awt.EventDispatchThread.pumpEvents(EventDispatchThread.java:161) at java.awt.EventDispatchThread.run(EventDispatchThread.java:122) Caused by: java.lang.ClassNotFoundException: Will not load class org.jdesktop.beansbinding.Converter arbitrarily from one of ModuleCL@738d08[org.jdesktop.beansbinding] and ModuleCL@167e3a5[javax.beans.binding] starting from SystemClassLoader[556 modules]; see http://wiki.netbeans.org/DevFaqModuleCCE at org.netbeans.ProxyClassLoader.loadClass(ProxyClassLoader.java:241) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at org.netbeans.modules.form.project.FormClassLoader.findClass(FormClassLoader.java:83) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:247) at org.netbeans.modules.form.project.ClassPathUtils.loadClass(ClassPathUtils.java:95) at org.netbeans.modules.form.FormUtils.loadClass(FormUtils.java:1445) at org.netbeans.modules.form.PersistenceObjectRegistry.loadClass(PersistenceObjectRegistry.java:95) at org.netbeans.modules.form.GandalfPersistenceManager.getClassFromString(GandalfPersistenceManager.java:5516) at org.netbeans.modules.form.GandalfPersistenceManager.getPropertyType(GandalfPersistenceManager.java:2348) ... 27 more msg Error in loading component property: Other Components-mainPanel-jTextField1-converter Cannot load property type class org.jdesktop.beansbinding.Converter.

  • XML: Process large data

    - by Atmocreations
    Hello What XML-parser do you recommend for the following purpose: The XML-file (formatted, containing whitespaces) is around 800 MB. It mostly contains three types of tag (let's call them n, w and r). They have an attribute called id which i'd have to search for, as fast as possible. Removing attributes I don't need could save around 30%, maybe a bit more. First part for optimizing the second part: Is there any good tool (command line linux and windows if possible) to easily remove unused attributes in certain tags? I know that XSLT could be used. Or are there any easy alternatives? Also, I could split it into three files, one for each tag to gain speed for later parsing... Speed is not too important for this preparation of the data, of course it would be nice when it took rather minutes than hours. Second part: Once I have the data prepared, be it shortened or not, I should be able to search for the ID-attribute I was mentioning, this being time-critical. Estimations using wc -l tell me that there are around 3M N-tags and around 418K W-tags. The latter ones can contain up to approximately 20 subtags each. W-Tags also contain some, but they would be stripped away. "All I have to do" is navigating between tags containing certain id-attributes. Some tags have references to other id's, therefore giving me a tree, maybe even a graph. The original data is big (as mentioned), but the resultset shouldn't be too big as I only have to pick out certain elements. Now the question: What XML parsing library should I use for this kind of processing? I would use Java 6 in a first instance, with having in mind to be porting it to BlackBerry. Might it be useful to just create a flat file indexing the id's and pointing to an offset in the file? Is it even necessary to do the optimizations mentioned in the upper part? Or are there parser known to be quite as fast with the original data? Little note: To test, I took the id being on the very last line on the file and searching for the id using grep. This took around a minute on a Core 2 Duo. What happens if the file grows even bigger, let's say 5 GB? I appreciate any notice or recommendation. Thank you all very much in advance and regards

  • Memory Troubles with UIImagePicker

    - by Dan Ray
    I'm building an app that has several different sections to it, all of which are pretty image-heavy. It ties in with my client's website and they're a "high-design" type outfit. One piece of the app is images uploaded from the camera or the library, and a tableview that shows a grid of thumbnails. Pretty reliably, when I'm dealing with the camera version of UIImagePickerControl, I get hit for low memory. If I bounce around that part of the app for a while, I occasionally and non-repeatably crash with "status:10 (SIGBUS)" in the debugger. On low memory warning, my root view controller for that aspect of the app goes to my data management singleton, cruises through the arrays of cached data, and kills the biggest piece, the image associated with each entry. Thusly: - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview. [super didReceiveMemoryWarning]; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Low Memory Warning" message:@"Cleaning out events data" delegate:nil cancelButtonTitle:@"All right then." otherButtonTitles:nil]; [alert show]; [alert release]; NSInteger spaceSaved; DataManager *data = [DataManager sharedDataManager]; for (Event *event in data.eventList) { spaceSaved += [(NSData *)UIImagePNGRepresentation(event.image) length]; event.image = nil; spaceSaved -= [(NSData *)UIImagePNGRepresentation(event.image) length]; } NSString *titleString = [NSString stringWithFormat:@"Saved %d on event images", spaceSaved]; for (WondrMark *mark in data.wondrMarks) { spaceSaved += [(NSData *)UIImagePNGRepresentation(mark.image) length]; mark.image = nil; spaceSaved -= [(NSData *)UIImagePNGRepresentation(mark.image) length]; } NSString *messageString = [NSString stringWithFormat:@"And total %d on event and mark images", spaceSaved]; NSLog(@"%@ - %@", titleString, messageString); // Relinquish ownership any cached data, images, etc that aren't in use. } As you can see, I'm making a (poor) attempt to eyeball the memory space I'm freeing up. I know it's not telling me about the actual memory footprint of the UIImages themselves, but it gives me SOME numbers at least, so I can see that SOMETHING'S happening. (Sorry for the hamfisted way I build that NSLog message too--I was going to fire another UIAlertView, but realized it'd be more useful to log it.) Pretty reliably, after toodling around in the image portion of the app for a while, I'll pull up the camera interface and get the low memory UIAlertView like three or four times in quick succession. Here's the NSLog output from the last time I saw it: 2010-05-27 08:55:02.659 EverWondr[7974:207] Saved 109591 on event images - And total 1419756 on event and mark images wait_fences: failed to receive reply: 10004003 2010-05-27 08:55:08.759 EverWondr[7974:207] Saved 4 on event images - And total 392695 on event and mark images 2010-05-27 08:55:14.865 EverWondr[7974:207] Saved 4 on event images - And total 873419 on event and mark images 2010-05-27 08:55:14.969 EverWondr[7974:207] Saved 4 on event images - And total 4 on event and mark images 2010-05-27 08:55:15.064 EverWondr[7974:207] Saved 4 on event images - And total 4 on event and mark images And then pretty soon after that we get our SIGBUS exit. So that's the situation. Now my specific questions: THE time I see this happening is when the UIPickerView's camera iris shuts. I click the button to take the picture, it does the "click" animation, and Instruments shows my memory footprint going from about 10mb to about 25mb, and sitting there until the image is delivered to my UIViewController, where usage drops back to 10 or 11mb again. If we make it through that without a memory warning, we're golden, but most likely we don't. Anything I can do to make that not be so expensive? Second, I have NSZombies enabled. Am I understanding correctly that that's actually preventing memory from being freed? Am I subjecting my app to an unfair test environment? Third, is there some way to programmatically get my memory usage? Or at least the usage for a UIImage object? I've scoured the docs and don't see anything about that.

  • Connecting to a WSE 3.0 Web Service From a WCF Client

    - by Dave
    I'm having difficulty connecting to a 3rd party WSE 3.0 web service from a WCF client. I have implemented the custom binding class as indicated in this KB article: http://msdn.microsoft.com/en-us/library/ms734745.aspx The problem seems to have to do with the security assertion used by the web service - UsernameOverTransport. When I attempt to call a method, I get the following exception: System.InvalidOperationException: The 'WseHttpBinding'.'[namespace]' binding for the 'MyWebServiceSoap'.'[namespace]' contract is configured with an authentication mode that requires transport level integrity and confidentiality. However the transport cannot provide integrity and confidentiality.. It is expecting a username, password, and CN number. In the example code supplied to us by the vendor, these credentials are bundled in a Microsoft.Web.Services3.Security.Tokens.UsernameToken. Here's the example supplied by the vendor: MyWebServiceWse proxy = new MyWebServiceWse(); UsernameToken token = new UsernameToken("Username", "password", PasswordOption.SendPlainText); token.Id = "<supplied CN Number>"; proxy.SetClientCredential(token); proxy.SetPolicy(new Policy(new UsernameOverTransportAssertion(), new RequireActionHeaderAssertion())); MyObject mo = proxy.MyMethod(); This works fine from a 2.0 app w/ WSE 3.0 installed. Here is a snippet of the code from my WCF client: EndpointAddress address = new EndpointAddress(new Uri("<web service uri here>")); WseHttpBinding binding = new WseHttpBinding(); // This is the custom binding I created per the MS KB article binding.SecurityAssertion = WseSecurityAssertion.UsernameOverTransport; binding.EstablishSecurityContext = false; // Not sure about the value of either of these next two binding.RequireDerivedKeys = true; binding.MessageProtectionOrder = MessageProtectionOrder.SignBeforeEncrypt; MembershipServiceSoapClient proxy = new MembershipServiceSoapClient(binding, address); // This is where I believe the problem lies – I can’t seem to properly setup the security credentials the web service is expecting proxy.ClientCredentials.UserName.UserName = "username"; proxy.ClientCredentials.UserName.Password = "pwd"; // How do I supply the CN number? MyObject mo = proxy.MyMethod(); // this throws the exception I've scoured the web looking for an answer to this question. Some sources get me close (like the MS KB article), but I can't seem to get over the hump. Can someone help me out?

  • How can I close a Window using the OS-X ScriptingBridge framework, from Perl?

    - by Gavin Brock
    Problem... Since MacPerl is no longer supported on 64bit perl, I am trying alternative frameworks to control Terminal.app. I am trying the ScriptingBridge, but have run into a problem passing an enumerated string to the closeSaving method using the PerlObjCBridge. I want to call: typedef enum { TerminalSaveOptionsYes = 'yes ' /* Save the file. */, TerminalSaveOptionsNo = 'no ' /* Do not save the file. */, TerminalSaveOptionsAsk = 'ask ' /* Ask the user whether or not to save the file. */ } TerminalSaveOptions; - (void) closeSaving:(TerminalSaveOptions)saving savingIn:(NSURL *)savingIn; // Close a document. Attempted Solution... I have tried: #!/usr/bin/perl use strict; use warnings; use Foundation; # Load the ScriptingBridge framework NSBundle->bundleWithPath_('/System/Library/Frameworks/ScriptingBridge.framework')->load; @SBApplication::ISA = qw(PerlObjCBridge); # Set up scripting bridge for Terminal.app my $terminal = SBApplication->applicationWithBundleIdentifier_("com.apple.terminal"); # Open a new window, get back the tab my $tab = $terminal->doScript_in_('exec sleep 60', undef); warn "Opened tty: ".$tab->tty->UTF8String; # Yes, it is a tab # Now try to close it # Simple idea eval { $tab->closeSaving_savingIn_('no ', undef) }; warn $@ if $@; # Try passing a string ref my $no = 'no '; eval { $tab->closeSaving_savingIn_(\$no, undef) }; warn $@ if $@; # Ok - get a pointer to the string my $pointer = pack("P4", $no); eval { $tab->closeSaving_savingIn_($pointer, undef) }; warn $@ if $@; eval { $tab->closeSaving_savingIn_(\$pointer, undef) }; warn $@ if $@; # Try a pointer decodes as an int, like PerlObjCBridge uses my $int_pointer = unpack("L!", $pointer); eval { $tab->closeSaving_savingIn_($int_pointer, undef) }; warn $@ if $@; eval { $tab->closeSaving_savingIn_(\$int_pointer, undef) }; warn $@ if $@; # Aaarrgghhhh.... As you can see, all my guesses at how to pass the enumerated string fail. Before you flame me... I know that I could use another language (ruby, python, cocoa) to do this but that would require translating the rest of the code. I might be able to use CamelBones, but I don't want to assume my users have it installed. I could also use the NSAppleScript framework (assuming I went to the trouble of finding the Tab and Window IDs) but it seems odd to have to resort to it for just this one call.

  • How to read the 3D chart data with directX?

    - by MemoryLeak
    I am reading a open source project, and I found there is a function which read 3D data(let's say a character) from obj file, and draw it . the source code: List<Vertex3f> verts=new List<Vertex3f>(); List<Vertex3f> norms=new List<Vertex3f>(); Groups=new List<ToothGroup>(); //ArrayList ALf=new ArrayList();//faces always part of a group List<Face> faces=new List<Face>(); MemoryStream stream=new MemoryStream(buffer); using(StreamReader sr = new StreamReader(stream)){ String line; Vertex3f vertex; string[] items; string[] subitems; Face face; ToothGroup group=null; while((line = sr.ReadLine()) != null) { if(line.StartsWith("#")//comment || line.StartsWith("mtllib")//material library. We build our own. || line.StartsWith("usemtl")//use material || line.StartsWith("o")) {//object. There's only one object continue; } if(line.StartsWith("v ")) {//vertex items=line.Split(new char[] { ' ' }); vertex=new Vertex3f();//float[3]; if(flipHorizontally) { vertex.X=-Convert.ToSingle(items[1],CultureInfo.InvariantCulture); } else { vertex.X=Convert.ToSingle(items[1],CultureInfo.InvariantCulture); } vertex.Y=Convert.ToSingle(items[2],CultureInfo.InvariantCulture); vertex.Z=Convert.ToSingle(items[3],CultureInfo.InvariantCulture); verts.Add(vertex); continue; } And why it need to read the data manually in directX? As far as I know, in XDA programming, we just need to call a function a load the resource. Is this because it is in DirectX, there is no function to read resource? If yes, then how to prepare the 3D resource ? in XDA we just need to use other software draw the 3D picture and then export. but what should I do in DirectX?

  • Project References DLL version hell

    - by Mr Shoubs
    We're having problems getting visual studio to pick up the latest version of a DLL from one of our projects. We have multiple class library projects (e.g. BusinessLogic, ReportData) and a number of web services, each has a reference to a Connectivity DLL we've written (this ref to the connectivity DLL is the problem). We always point references to the DLL in the bin/debug folder, (which is where we always build to for any given project) and all custom DLL references have CopyLocal = True and SpecificVersion = False ReportData has a reference to business logic (which also has a reference to connectivity - I don't see why this should cause a problem, but thought it is worth mentioning) The weird thing is, when you click "Add Reference" and browse to Connectivity/bin/debug - you hover the mouse over the DLL file, the correct (latest) version is shown (version and file version are always incremented together), but when you click ok, a previous version number is pulled though. Even when I look in the current projects debug folder (where copy local would put the DLL after compiling) that shows the latest version number. - NO WHERE does can I find the previous version of the DLL outside of visual studio, but in that project references it has the old version - even though the path is correct. I'm at a loss as to where it might be getting the old versions from. Or even why it wants that one. This is possibly the most frustraighting problem I have ever come across. Does anyone know how to ensure the latest version is pulled through (preferably automatically or on compile). EDIT: Although not exactly the scenario I'm dealing with I was reading this article and somewhere it mentions about CLR ignoring revision numbers. Understandable (even though this hasn't been a problem before - we're on revision 39), so I thought I would update the build number, still didn't work. In a vain attempt I though I would update the minor version number and see if that made any difference. I'm not saying this is the answer as I have to check quite a few things first, but on the face of it, this seems to have solved my problem... Further edit: In other class libraries this seems to have solved the problem, however in a test windows application it still pulls a previous version through :( If I increment the minor version number again, the same problem come back and I am left with the wrong version being pulled though. Further Edit - I created an entirly new project, added a reference and still had the exact same problem. This suggests the problem is restriced to the project I am referencing. Wish I knew why! Anyone had this problem before and know how to get around it? HELP!

  • flickr phpflickr api

    - by sea_1987
    Overview I am trying to get a photo feed on to my site using Flickr's api and the phpflickr library. I can successfully get the photoset on to my site, but it shows all the photos from every photoset, what I was hoping to achieve was to show the primary photo from each photoset, and then if the user clicked on the image it would show the full photoset in a lightbox/shadowbox. My Code <div id="images" class="tabnav"> <ul class="items"> <?php $count = 1; ?> <?php foreach ($photosets['photoset'] as $ph_set): ?> <?php $parentID = $ph_set['parent']; ?> <?php $photoset_id = $ph_set['id']; $photos = $f->photosets_getPhotos($photoset_id); foreach ($photos['photoset']['photo'] as $photo): ?> <li> <a rel="shadowbox['<?=$count;?>']" href="<?= $f->buildPhotoURL($photo, 'medium') ?>" title="<?= $photo['title'] ?>"> <img src="<?= $f->buildPhotoURL($photo, 'rectangle') ?>" alt="<?= $photo['title'] ?>" width="210" height="160" title="<?= $photo['title'] ?>" /> <h3><?=$ph_set['title']?></h3> <p><?=$ph_set['description'];?></p> </a> </li> <?php endforeach; ?> <?php $count++; ?> <?php endforeach; ?> </ul> </div> Another Attempt I have also tried calling the getPhotos function differently, instead of sending it without any parameters I sent it with parameters $photos = $f->photosets_getPhotos($photoset_id, NULL, NULL, 1, NULL); The above code stopped the showing all the photos from each photoset and started showing just the primary image, but it also stopped making the rest of the photos accesible to me. Is there something I can do to make this work? I am totally out iof ideas. Regards and thanks

  • Does anyone have database, programming language/framework suggestions for a GUI point of sale system

    - by Jason Down
    Our company has a point of sale system with many extras, such as ordering and receiving functionality, sales and order history etc. Our main issue is that the system was not designed properly from the ground up, so it takes too long to make fixes and handle requests from our customers. Also, the current technology we are using (Progress database, Progress 4GL for the language) incurs quite a bit of licensing expenses on our customers due to mutli-user license fees for database connections etc. After a lot of discussion it is looking like we will probably start over from scratch (while maintaining the current product at least for the time being). We are looking for a couple of things: Create the system with a nice GUI front end (it is currently CHUI and the application was not built in a way that allows us to redesign the front end... no layering or separation of business logic and gui...shudder). Create the system with the ability to modularize different functionality so the product doesn't have to include all features. This would keep the cost down for our current customers that want basic functionality and a lower price tag. The bells and whistles would be available for those that would want them. Use proper design patterns to make the product easy to add or change any part at any time (i.e. change the database or change the front end without needing to rewrite the application or most of it). This is a problem today because the Progress 4GL code is directly compiled against the database. Small changes in the database requires lots of code recompiling. Our new system will be Linux based, with a possibility of a client application providing functionality from one or more windows boxes. So what I'm looking for is any suggestions on which database and/or framework or programming language(s) someone might recommend for this sort of product. Anyone that has experience in this field might be able to point us in the right direction or even have some ideas of what to avoid. We have considered .NET and SQL Express (we don't need an enterprise level DB), but that would limit us to windows (as far as I know anyway). I have heard of Mono for writing .NET code in a Linux environment, but I don't know much about it yet. We've also considered a Java and MySql based implementation. To summarize we are looking to do the following: Keep licensing costs down on the technology we will use to develop the product (Oracle, yikes! MySQL, nice.) Deliver a solution that is easily maintainable and supportable. A solution that has a component capable of running on "old" hardware through a CHUI front end. (some of our customers have 40+ terminals which would be a ton of cash in order to convert over to a PC). Suggestions would be appreciated. Thanks [UPDATE] I should note that we are currently performing a total cost analysis. This question is intended to give us a couple of "educated" options to look into to include in or analysis. Anyone who could share experiences/suggestions about client/server setups would be appreciated (not just those who have experience with point of sale systems... that would just be a bonus).

  • Beginner - C# iteration through directory to produce a file list

    - by dassouki
    The end goal is to have some form of a data structure that stores a hierarchal structure of a directory to be stored in a txt file. I'm using the following code and so far, and I'm struggling with combining dirs, subdirs, and files. /// <summary> /// code based on http://msdn.microsoft.com/en-us/library/bb513869.aspx /// </summary> /// <param name="strFolder"></param> public static void TraverseTree ( string strFolder ) { // Data structure to hold names of subfolders to be // examined for files. Stack<string> dirs = new Stack<string>( 20 ); if ( !System.IO.Directory.Exists( strFolder ) ) { throw new ArgumentException(); } dirs.Push( strFolder ); while ( dirs.Count > 0 ) { string currentDir = dirs.Pop(); string[] subDirs; try { subDirs = System.IO.Directory.GetDirectories( currentDir ); } catch ( UnauthorizedAccessException e ) { MessageBox.Show( "Error: " + e.Message ); continue; } catch ( System.IO.DirectoryNotFoundException e ) { MessageBox.Show( "Error: " + e.Message ); continue; } string[] files = null; try { files = System.IO.Directory.GetFiles( currentDir ); } catch ( UnauthorizedAccessException e ) { MessageBox.Show( "Error: " + e.Message ); continue; } catch ( System.IO.DirectoryNotFoundException e ) { MessageBox.Show( "Error: " + e.Message ); continue; } // Perform the required action on each file here. // Modify this block to perform your required task. /* foreach ( string file in files ) { try { // Perform whatever action is required in your scenario. System.IO.FileInfo fi = new System.IO.FileInfo( file ); Console.WriteLine( "{0}: {1}, {2}", fi.Name, fi.Length, fi.CreationTime ); } catch ( System.IO.FileNotFoundException e ) { // If file was deleted by a separate application // or thread since the call to TraverseTree() // then just continue. MessageBox.Show( "Error: " + e.Message ); continue; } } */ // Push the subdirectories onto the stack for traversal. // This could also be done before handing the files. foreach ( string str in subDirs ) dirs.Push( str ); foreach ( string str in files ) MessageBox.Show( str ); }

  • Automatically generate table of function pointers in C.

    - by jeremytrimble
    I'm looking for a way to automatically (as part of the compilation/build process) generate a "table" of function pointers in C. Specifically, I want to generate an array of structures something like: typedef struct { void (*p_func)(void); char * funcName; } funcRecord; /* Automatically generate the lines below: */ extern void func1(void); extern void func2(void); /* ... */ funcRecord funcTable[] = { { .p_func = &func1, .funcName = "func1" }, { .p_func = &func2, .funcName = "func2" } /* ... */ }; /* End automatically-generated code. */ ...where func1 and func2 are defined in other source files. So, given a set of source files, each of which which contain a single function that takes no arguments and returns void, how would one automatically (as part of the build process) generate an array like the one above that contains each of the functions from the files? I'd like to be able to add new files and have them automatically inserted into the table when I re-compile. I realize that this probably isn't achievable using the C language or preprocessor alone, so consider any common *nix-style tools fair game (e.g. make, perl, shell scripts (if you have to)). But Why? You're probably wondering why anyone would want to do this. I'm creating a small test framework for a library of common mathematical routines. Under this framework, there will be many small "test cases," each of which has only a few lines of code that will exercise each math function. I'd like each test case to live in its own source file as a short function. All of the test cases will get built into a single executable, and the test case(s) to be run can be specified on the command line when invoking the executable. The main() function will search through the table and, if it finds a match, jump to the test case function. Automating the process of building up the "catalog" of test cases ensures that test cases don't get left out (for instance, because someone forgets to add it to the table) and makes it very simple for maintainers to add new test cases in the future (just create a new source file in the correct directory, for instance). Hopefully someone out there has done something like this before. Thanks, StackOverflow community!

  • Custom validator not invoked when using Validation Application Block through configuration

    - by Chris
    I have set up a ruleset in my configuration file which has two validators, one of which is a built-in NotNullValidator, the other of which is a custom validator. The problem is that I see the NotNullValidator hit, but not my custom validator. The custom validator is being used to validate an Entity Framework entity object. I have used the debugger to confirm the NotNull is hit (I forced a failure condition so I saw it set an invalid result), but it never steps into the custom one. I am using MVC as the web app, so I defined the ruleset in a config file at that layer, but my custom validator is defined in another project. However, I wouldn't have thought that to be a problem because when I use the Enterprise Library Configuration tool inside Visual Studio 2008 it is able to set the type properly for the custom validator. As well, I believe the custom validator is fine as it builds ok, and the config tool can reference it properly. Does anybody have any ideas what the problem could be, or even what to do/try to debug further? Here is a stripped down version of my custom validator: [ConfigurationElementType(typeof(CustomValidatorData))] public sealed class UserAccountValidator : Validator { public UserAccountValidator(NameValueCollection attributes) : base(string.Empty, "User Account") { } protected override string DefaultMessageTemplate { get { throw new NotImplementedException(); } } protected override void DoValidate(object objectToValidate, object currentTarget, string key, ValidationResults results) { if (!currentTarget.GetType().Equals(typeof(UserAccount))) { throw new Exception(); } UserAccount userAccountToValidate = (UserAccount)currentTarget; // snipped code ... this.LogValidationResult(results, "The User Account is invalid", currentTarget, key); } } Here is the XML of my ruleset in Validation.config (the NotNull rule is only there to force a failure so I could see it getting hit, and it does): <validation> <type defaultRuleset="default" assemblyName="MyProj.Entities, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" name="MyProj.Entities.UserAccount"> <ruleset name="default"> <properties> <property name="HashedPassword"> <validator negated="true" messageTemplate="" messageTemplateResourceName="" messageTemplateResourceType="" tag="" type="Microsoft.Practices.EnterpriseLibrary.Validation.Validators.NotNullValidator, Microsoft.Practices.EnterpriseLibrary.Validation, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="Not Null Validator" /> </property> <property name="Property"> <validator messageTemplate="" messageTemplateResourceName="" messageTemplateResourceType="" tag="" type="MyProj.Entities.UserAccountValidator, MyProj.Entities, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" name="Custom Validator" /> </property> </properties> </ruleset> </type> </validation> And here is the stripped down version of the way I invoke the validation: var type = entity.GetType() var validator = ValidationFactory.CreateValidator(type, "default", new FileConfigurationSource("Validation.config")) var results = validator.Validate(entity) Any advice would be much appreciated! Thanks, Chris

  • Succinct introduction to C++/CLI for C#/Haskell/F#/JS/C++/... programmer

    - by Henrik
    Hello everybody, I'm trying to write integrations with the operating system and with things like active directory and Ocropus. I know a bunch of programming languages, including those listed in the title. I'm trying to learn exactly how C++/CLI works, but can't find succinct, exact and accurate descriptions online from the searching that I have done. So I ask here. Could you tell me the pitfalls and features of C++/CLI? Assume I know all of C# and start from there. I'm not an expert in C++, so some of my questions' answers might be "just like C++", but could say that I am at C#. I would like to know things like: Converting C++ pointers to CLI pointers, Any differences in passing by value/doubly indirect pointers/CLI pointers from C#/C++ and what is 'recommended'. How do gcnew, __gc, __nogc work with Polymorphism Structs Inner classes Interfaces The "fixed" keyword; does that exist? Compiling DLLs loaded into the kernel with C++/CLI possible? Loaded as device drivers? Invoked by the kernel? What does this mean anyway (i.e. to load something into the kernel exactly; how do I know if it is?)? L"my string" versus "my string"? wchar_t? How many types of chars are there? Are we safe in treating chars as uint32s or what should one treat them as to guarantee language indifference in code? Finalizers (~ClassName() {}) are discouraged in C# because there are no garantuees they will run deterministically, but since in C++ I have to use "delete" or use copy-c'tors as to stack allocate memory, what are the recommendations between C#/C++ interactions? What are the pitfalls when using reflection in C++/CLI? How well does C++/CLI work with the IDisposable pattern and with SafeHandle, SafeHandleZeroOrMinusOneIsInvalid? I've read briefly about asynchronous exceptions when doing DMA-operations, what are these? Are there limitations you impose upon yourself when using C++ with CLI integration rather than just doing plain C++? Attributes in C++ similar to Attributes in C#? Can I use the full meta-programming patterns available in C++ through templates now and still have it compile like ordinary C++? Have you tried writing C++/CLI with boost? What are the optimal ways of interfacing the boost library with C++/CLI; can you give me an example of passing a lambda expression to an iterator/foldr function? What is the preferred way of exception handling? Can C++/CLI catch managed exceptions now? How well does dynamic IL generation work with C++/CLI? Does it run on Mono? Any other things I ought to know about?
