  • UIPageControl in a ITableViewCell gets shoved to the top left corner

    - by Danny Tuppeny
    I'm trying to put a UIPageControl inside a cell (there's nothing else in the cell), but I have two problems: The dots are aligned at the top-left of the cell, so you only see the bottom-right quarter of the first dot, and the bottom half of the other dots (like the first dots center is 0, 0). Unless you tab the cell to select it (goes blue), you can't see the dots at all. Other controls I've put into a cell have filled the whole area as wanted. How do I tell the UIPageControl to fill the whole cell (and align in the middle) How do I change the colours so the dots can be seen? I tried calling [pageControl setBackgroundColor] but it didn't seem to do anything. Here's the code I'm using: // Create a page control UIPageControl *pageControl = [[[UIPageControl alloc] init] autorelease]; // Set the number of pages to match the images [pageControl setNumberOfPages:[imageFilenames count]]; [pageControl setCurrentPage:1]; // Create the cell and add the paging control UITableViewCell *cell = [self getCell:tableView withIdentifier:@"ImagePager"]; [cell addSubview:pageControl]; //[[cell textLabel] setText:@"ADD PAGING CONTROL"]; return cell;

  • WPF Memory Leak on XP (CMilChannel, HWND)

    - by vanja.
    My WPF application leaks memory at about 4kb/s. The memory usage in Task Manager climbs constantly until the application crashes with an "Out of Memory" exception. By doing my own research I have found that the problem is discussed here: http://stackoverflow.com/questions/801589/track-down-memory-leak-in-wpf and #8 here: http://blogs.msdn.com/jgoldb/archive/2008/02/04/finding-memory-leaks-in-wpf-based-applications.aspx The problem described is: This is a leak in WPF present in versions of the framework up to and including .NET 3.5 SP1. This occurs because of the way WPF selects which HWND to use to send messages from the render thread to the UI thread. This sample destroys the first HWND created and starts an animation in a new Window. This causes messages sent from the render thread to pile up without being processed, effectively leaking memory. The solution offered is: The workaround is to create a new HwndSource first thing in your App class constructor. This MUST be created before any other HWND is created by WPF. Simply by creating this HwndSource, WPF will use this to send messages from the render thread to the UI thread. This assures all messages will be processed, and that none will leak. But I don't understand the solution! I have a subclass of Application that I am using and I have tried creating a window in that constructor but that has not solved the problem. Following the instructions given literally, it looks like I just need to add this to my Application constructor: new HwndSource(new HwndSourceParameters("MyApplication"));

  • Imagemagick PDF to JPG conversion failing

  • How can I use removeFromSuperView and dismissModalViewControllerAnimated at same time ?

    - by srikanth rongali
    I have a UIViewController *view1 and another UIViewController *view2; I used presentModelViewController to navigate from view1 to view2. -(void)function:(id)sender { NSLog(@"The libraryFunction entered"); LibraryController *libraryController = [[LibraryController alloc]init]; [self presentModalViewController:libraryController animated:YES]; } I have another view UITableViewController *tableView; I added it to view2 as a subView. -(void)viewDidLoad { RootViewController *rootViewController = [[RootViewController alloc] initWithStyle:UITableViewStylePlain]; UINavigationController *aNavigationController = [[UINavigationController alloc] initWithRootViewController:rootViewController]; self.navController = aNavigationController; [aNavigationController release]; [rootViewController release]; navController.view.frame = CGRectMake(0, 0, 320, 460); [self.view addSubview:navController.view]; } In RootViewController.m I have - (void)viewDidLoad { [super viewDidLoad]; self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Close" style:UIBarButtonItemStyleBordered target:self action:@selector(close:)]; } -(void)close:(id)sender { [self.view removeFromSuperview]; [self dismissModalViewControllerAnimated:YES]; } WhenI touch close button I need to return the view1. So, I removed the tableView by using removeFromSuperView. But, I am not able to get to the first view. I do not get where to use - (void)dismissModalViewControllerAnimated:(BOOL)animated; to navigate to first view1 where I have started ? How can I do this ? Thank You.

  • WPF custom BalloonTips problem with multithreading

    - by Erika
    Hi, I have read other related question but i cant really get them to relate to this so I thought it were best to ask, Im pretty new to WPF and so on so please bear with me. I am using this http://www.codeproject.com/KB/WPF/wpf_notifyicon.aspx api to work with custom WPF Windows (in particular FancyBalloon). However, i'm coming across the following problem, I seem unable to start off BalloonTips in a separate thread ( i need this because i'm parsing emails and hence if there are 3 emails for instance, it displays the first email (that works fine), but when it comes to the second email it crashes with a TargetInvocationException , {"Specified element is already the logical child of another element. Disconnect it first."}. Thing is, im supposedly working with the same instance and i have attempted calling it to close it before, disposing it etc but to no avail. (then again if i dispose it, i cant create another instance as apparently WPF UI components must be called from a static thread so throughout the looping of emails + displaying balloon, i am trying to use the same BalloonTip. Any suggestions please? I am really at a loss here and i've been on it for quite a while now :/ I was wondering if there was anyone

  • Multiple overlay items in android

    - by Bostjan
    I seem to be having a problem with using ItemizedOverlay and OveralyItems in it. I can get the first overlayItem to appear on the map but not any items after that. Code sample is on: http://www.anddev.org/multiple_overlay_items-t12171.html Quick overview here: public class Markers extends ItemizedOverlay { private Context ctx; private ArrayList<OverlayItem> mOverlays = new ArrayList<OverlayItem>(); public Markers(Drawable defaultMarker, Context cont) { super(boundCenterBottom(defaultMarker)); this.ctx = cont; // TODO Auto-generated constructor stub } @Override protected OverlayItem createItem(int i) { // TODO Auto-generated method stub return mOverlays.get(i); } @Override public boolean onTap(GeoPoint p, MapView mapView) { // TODO Auto-generated method stub return super.onTap(p, mapView); } @Override protected boolean onTap(int index) { // TODO Auto-generated method stub Toast.makeText(this.ctx, mOverlays.get(index).getTitle().toString()+", Latitude: "+mOverlays.get(index).getPoint().getLatitudeE6(), Toast.LENGTH_SHORT).show(); return super.onTap(index); } @Override public int size() { // TODO Auto-generated method stub return mOverlays.size(); } public void addOverlay(OverlayItem item) { mOverlays.add(item); setLastFocusedIndex(-1); populate(); } public void clear() { mOverlays.clear(); setLastFocusedIndex(-1); populate(); }} Markers usersMarker = new Markers(user,overview.this); GeoPoint p = new GeoPoint((int) (lat * 1E6),(int) (lon * 1E6)); OverlayItem item = new OverlayItem(p,userData[0],userData[3]); item.setMarker(this.user); usersMarker.addOverlay(item); The lines after the class are just samples of how it's used the first marker shows up on the map but if I add any more they don't show up? Is there a problem with the populate() method? I tried calling it manually after adding all markers but it still didn't help. Please, if you have any idea what could be wrong, say so.

  • Cast then check or check then cast?

    - by jamesrom
    Which method is regarded as best practice? Cast first? public string Describe(ICola cola) { var coke = cola as CocaCola; if (coke != null) { string result; // some unique coca-cola only code here. return result; } var pepsi = cola as Pepsi; if (pepsi != null) { string result; // some unique pepsi only code here. return result; } } Or should I check first, cast later? public string Describe(ICola cola) { if (cola is CocaCola) { coke = (CocaCola) cola; string result; // some unique coca-cola only code here. return result; } if (cola is Pepsi) { pepsi = (Pepsi) cola; string result; // some unique pepsi only code here. return result; } } Can you see any other way to do this?

  • Objective-C : Fowler–Noll–Vo (FNV) Hash implementation

    - by Dough
    Hi ! I have a HTTP connector in my iPhone project and queries must have a parameter set from the username using the Fowler–Noll–Vo (FNV) Hash. I have a Java implementation working at this time, this is the code : long fnv_prime = 0x811C9DC5; long hash = 0; for(int i = 0; i < str.length(); i++) { hash *= fnv_prime; hash ^= str.charAt(i); } Now on the iPhone side, I did this : int64_t fnv_prime = 0x811C9DC5; int64_T hash = 0; for (int i=0; i < [myString length]; i++) { hash *= fnv_prime; hash ^= [myString characterAtIndex:i]; } This script doesn't give me the same result has the Java one. In first loop, I get this : hash = 0 hash = 100 (first letter is "d") hash = 1865261300 (for hash = 100 and fnv_prime = -2128831035 like in Java) Do someone see something I'm missing ? Thanks in advance for the help !

  • Mercurial Tagging/Branching Strategy

    - by Tony Trozzo
    My current project is broken down into 3 parts: Website, Desktop Client, and a Plug-in for a third party program. We had started out originally with Subversion for our source control but decided to try Mercurial after reading Joel Spolsky's final post. Considering we haven't really used the majority of svn's potential before, we figured starting fresh with some basic ideas of how source control worked would make this transition easy. However, after setting up our initial repository, we're lost as to how tagging and branching should work on a project like this. Essentially, we're working on all 3 of these parts at the same time. We want a release to be a combination of the 3 parts. Currently we're working in one repository. For the Plug-in part, we have the first iteration finished which we've been referring to as Plug-In v0.1. For the first official build of the other two parts, we'd also like to refer to them as Website v0.1 and Desktop Client v0.1. When all three parts are at v0.1, we'd like to have a Full Project v0.1. Our problem is we're not sure how to manage all of this in the Hg repository. Would the best way to handle this be to create 3 separate repositories for the 3 stable versions and then 3 more repositories for the current developments? Currently we have this all in one repository. Should we do this in branches (are branches any different from cloning repositories?) and tags? Any help is greatly appreciated.

  • Delphi SAPI Text-To-Speech

    - by Andreas Rejbrand
    First of all: this is not a duplicate of http://stackoverflow.com/questions/1021490/delphi-and-sapi. I have a specific problem with the "SAPI in Delphi" subject. I have used the excellent Import Type-Library guide in Delphi 2009 to get a TSpVoice component in the component palette. This works great. With var SpVoice: TSpVoice; I can write SpVoice.Speak('This is an example.', 1); to get asynchronous audio output. First question According to the documentation, I would be able to write SpVoice.Speak('This is an example.', 0); to get synchronous audio output, but instead I get an EZeroDivide exception. Why's that? Second question But more importantly, I would like to be able to create the SpVoice object dynamically (I think this is called to "late-bound" the SpVoice object), partly because only a very small fraction of all sessions of my app will use it, and partly because I do not want to assume the existance of the SAPI server on the end-user's system. To this end, I tried procedure TForm1.FormClick(Sender: TObject); var SpVoice: Variant; begin SpVoice := CreateOleObject('SAPI.SpVoice'); SpVoice.Speak('this is a test', 0); end; which apparently does nothing at all! (Replacing the 0 with 1 gives me the EZeroDivide exception.) Disclaimer I am rather new to COM/OLE automation. I am sorry for any ignorance or stupidity shown by me in this post...

  • How do I save an Android application's state?

    - by Bernard
    I've been playing around with the Android SDK, and I am a little unclear on saving an applications state. So given this minor re-tooling of the 'Hello, Android' example: package com.android.hello; import android.app.Activity; import android.os.Bundle; import android.widget.TextView; public class HelloAndroid extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mTextView = new TextView(this); if (savedInstanceState == null) { mTextView.setText("Welcome to HelloAndroid!"); } else { mTextView.setText("Welcome back."); } setContentView(mTextView); } private TextView mTextView = null; } I thought that might be all one needed to do for the simplest case, but it always gives me the first message, no matter how I navigate away from the app. I'm sure it's probably something simple like overriding onPause or something like that, but I've been poking away in the docs for 30 minutes or so and haven't found anything obvious, so would appreciate any help. Cue me looking a fool in three, two, one... Thanks.

  • Tricky SQL query involving consecutive values

    - by Gabriel
    I need to perform a relatively easy to explain but (given my somewhat limited skills) hard to write SQL query. Assume we have a table similar to this one: exam_no | name | surname | result | date ---------+------+---------+--------+------------ 1 | John | Doe | PASS | 2012-01-01 1 | Ryan | Smith | FAIL | 2012-01-02 <-- 1 | Ann | Evans | PASS | 2012-01-03 1 | Mary | Lee | FAIL | 2012-01-04 ... | ... | ... | ... | ... 2 | John | Doe | FAIL | 2012-02-01 <-- 2 | Ryan | Smith | FAIL | 2012-02-02 2 | Ann | Evans | FAIL | 2012-02-03 2 | Mary | Lee | PASS | 2012-02-04 ... | ... | ... | ... | ... 3 | John | Doe | FAIL | 2012-03-01 3 | Ryan | Smith | FAIL | 2012-03-02 3 | Ann | Evans | PASS | 2012-03-03 3 | Mary | Lee | FAIL | 2012-03-04 <-- Note that exam_no and date aren't necessarily related as one might expect from the kind of example I chose. Now, the query that I need to do is as follows: From the latest exam (exam_no = 3) find all the students that have failed (John Doe, Ryan Smith and Mary Lee). For each of these students find the date of the first of the batch of consecutively failing exams. Another way to put it would be: for each of these students find the date of the first failing exam that comes after their last passing exam. (Look at the arrows in the table). The resulting table should be something like this: name | surname | date_since_failing ------+---------+-------------------- John | Doe | 2012-02-01 Ryan | Smith | 2012-01-02 Mary | Lee | 2012-01-04 Ann | Evans | 2012-02-03 How can I perform such a query? Thank you for your time.

  • jQuery datepicker validation message issue

    - by Abhishek
    Hi, I'm using the jquery datepicker plugin at http://plugins.jquery.com/project/datepick with the datepicker validation plugin. <script id="frmValidation" type="text/javascript"> $(document).ready(function(){ var validator = $("#frmTest").validate({ rules:{ fname: "required", dobPicker: "required" }, messages:{ fname: "Please enter a name", dobPicker: "Select a date" }, }); $('#dobPicker').datepick(); $.datepick.setDefaults({showOn: 'both', dateFormat: 'dd-mm-yy', yearRange:'1900:2010'}); }); </script> And the body of the document is as follows : <form id="frmTest" action="" method="post"> <div id="error-list"></div> <div class="form-row"> <span class="label"><label for="fname">Name</label></span> <input type="text" name="fname" /> </div> <div class="form-row"> <span class="label"><label for="dobPicker">DOB</label></span> <input type="text" id="dobPicker" name="dobPicker" style="margin-left: 4px;"/> </div> <div class="form-row"> <input type="submit" name="submit" value="submit"/> </div> </form> The form validates the first time but the error message for the datepicker does not disappear immediately a date is selected.. however it goes away if the date is selected the second time. Any help to make it go the first time a date is selected will be appreciated

  • Flex, Ant, mxmlc and conditional compilation

    - by Rezmason
    My ActionScript project builds with several compile-time specified constants. They are all Booleans, and only one of them is true at any given time. The rest must be false. When I represented my build process in a bash script, I could loop through the names of all these constants, set one of them to be true and the rest to be false, then concatenate them onto a string to be inserted as a set of arguments passed to mxmlc. In Ant, looping is more complicated. I've tried the ant-contrib for tag: <mxmlc file='blah' output='blah'> <!- ... -> <for list='${commaSeparatedListOfConstNames}' param='constName'> <sequential> <define> <name>${constName}</name> <value>${constName} == ${theTrueConst}</value> <!-- (mxmlc's define arguments can be strings that are evaluated at compile time) --> </define> </sequential> </for> </mxmlc> Long story short, ant-contrib tags like the for tag can't go in the mxmlc task. So now I'm using Ant's propertyregex to take my list of arguments and format them into a set of define args, like my old bash script: <propertyregex property='defLine.first' override='false' input='${commaSeparatedListOfConstNames}' regexp='([^\|]+)\,' replace='\1,false ' /> <propertyregex property='defLine.final' input='${defLine.first}' regexp='(@{theTrueConst}\,)false' replace='\1true' /> <!-- result: -define+=CONST_ONE,false -define+=CONST_TWO,false -define+=TRUE_CONST,true --> Now my problem is, what can I do with this mxmlc argument and the mxmlc task? Apparently arg tags can go inside the mxmlc task without it throwing an error, but they don't seem to have any effect. What am I supposed to do? How do I make this work with the mxmlc task?

  • Android: Dialog themed activity not visible

    - by Vincent
    I have an activity which, when started, needs to check if the user is authenticated. If not, I need to display an interface to authenticate. I do this with another activity, which has a dialog theme, and I start it in onResume() with flags NO_HISTORY and EXCLUDE_FROM_RECENTS. Everything works fine when starting the application for the first time. But I have a feature that resets login after some time, if the user is not in an activity. When I test this, I start the applicatio, enter the password, then move back to home. Then when I enter the application again, the background darkens as if the dialog would show, but it doesn't. At this point, if I press the back button, the darkening from the background activity disappears for a second, then the dialog finally appears. I used logcat to investigate the case, and the activity lifecycle functions get called properly: //For the first start: onCreate background activity onStart background activity onResume background activity onPause background activity onCreate dialog onStart dialog onResume dialog //Enter password onPause dialog onResume background activity onStop dialog onDestroy dialog //navigating to homescreen onPause background activity onStop background activity //starting again onRestart background activity onStart background activity onResume background activity onPause background activity onCreate dialog onStart dialog onResume dialog //no dialog shown, only darkened background activity recieving no input //pressing back button onPause dialog onResume background activity onPause background activity onCreate NEW dialog onStart NEW dialog onResume NEW dialog onStop OLD dialog onDestroy OLD dialog //now the dialog is properly shown //entering password onPause NEW dialog onResume background activity onStop NEW dialog onDestroy NEW dialog Using the SINGLE_TOP flag makes no change. However, if I remove the dialog theme from the dialog activity, it IS shown after the restart. So far I didn't want to use a Dialog instead of an Activity, because I consider them problematic sometimes and less encapsulated and this part has to be quite secure. You may be able to convince me though.. Thank you in advance!

  • How to extend an 'unloadable' Rails plugin?

    - by Vitaly Kushner
    I'm trying to write a plugin that will extend InheritedResources. Specifically I want to rewrite some default helpers. And I'd like it to "just work" once installed, w/o any changes to application code. The functionality is provided in a module which needs to be included in a right place. The question is where? :) The first attempt was to do it in my plugin's init.rb: InheritedResources::Base.send :include, MyModule It works in production, but fails miserably in development since InheritedResource::Base declared as unloadable and so its code is reloaded on each request. So my module is there for the first request, and then its gone. InheritedResource::Base is 'pulled' in again by any controller that uses it: Class SomeController < InheritedResource::Base But no code is 'pulling in' my extension module since it is not referenced anywhere except init.rb which is not re-loaded on each request So right now I'm just including the module manually in every controller that needs it which sucks. I can't even include it once in ApplicationController because InheritedResources inherites from it and so it will override any changes back. update I'm not looking for advice on how to 'monkey patch'. The extension is working in production just great. my problem is how to catch moment exactly after InheritedResources loaded to stick my extension into it :) update2 another attempt at clarification: the sequence of events is a) rails loads plugins. my plugin loads after inherited_resources and patches it. b) a development mode request is served and works c) rails unloads all the 'unloadable' code which includes all application code and also inherited_resources d) another request comes in e) rails loads controller, which inherites from inherited resources f) rails loads inherited resources which inherit from application_controller g) rails loads application_contrller (or may be its already loaded at this stage, not sure) g) request fails as no-one loaded my plugin to patch inherited_resources. plugin init.rb files are not reloaded I need to catch the point in time between g and h

  • UINavigationController crash because of pushing and poping UIViewControllers

    - by Wayne Lo
    My question is related to my discovery of a reason for UINavigationController to crash. So I will tell you about the discovery first. Please bare with me. The issue: I have a UINavigationController as as subview of UIWindow, a rootViewController class and a custom MyViewController class. The following steps will get a Exc_Bad_Access, 100% reproducible.: [myNaviationController pushViewController:myViewController_1stInstance animated:YES]; [myNaviationController pushViewController:myViewController_2ndInstance animated:YES]; Hit the left back tapBarItem twice (pop out two of the myViewController instances) to show the rootViewController. After a painful 1/2 day of try and error, I finally figure out the answer but also raise a question. The Solutio: I declared many objects in the .m file as a lazy way of declaring private variables to avoid cluttering the .h file. For instance, #impoart "MyViewController.h" NSMutableString*variable1; @implement ... -(id)init { ... varialbe1=[[NSMutableString alloc] init]; ... } -(void)dealloc { [variable1 release]; } For some reasons, the iphone OS may loose track of these "lazy private" variables memory allocation when myViewController_1stInstance's view is unloaded (but still in the navigation controller's stacks) after loading the view of myViewController_2ndInstance. The first time to tap the back tapBarItem is ok since myViewController_2ndInstance'view is still loaded. But the 2nd tap on the back tapBarItem gave me hell because it tried to dealloc the 2nd instance. Executing [variable release] resulted in Exc_Bad_Access because it pointed randomly (loose pointer). To fix this problem is simple, declare variable1 as a @private in the .h file. Here is my Question: I have been using the "lazy private" variables for quite some time without any issues until they are involved in UINavigationController. Is this a bug in iPhone OS? Or there is a fundamental misunderstanding on my part about Objective C? Please help.

  • Complex regex question, data may or may not be in brackets

    - by martinpetts
    I need to extract data from a source that presents it in one of two ways. The data could be formatted like this: Francis (Lab) 18,077 (60.05%); Waller (LD) 4,140 (13.75%); Evans (PC) 3,545 (11.78%); Rees-Mogg (C) 3,064 (10.18%); Wright (Veritas) 768 (2.55%); La Vey (Green) 510 (1.69%) Or like this: Lab 8,994 (33.00%); C 7,924 (29.07%); LD 5,197 (19.07%); PC 3,818 (14.01%); Others 517 (1.90%); Green 512 (1.88%); UKIP 296 (1.09%) The data I need to extract is the percentage and the party (these are election results), which is either in brackets (first example) or is the only non-numeric text. So far I have this: preg_match('/(.*)\(([^)]*)%\)/', $value, $match); Which is giving me the following matches (for first example): Array ( [0] => Francis (Lab) 18,077 (60.05%) [1] => Francis (Lab) 18,077 [2] => 60.05 ) So I have the percentage, but I also need the party label, which may or may not be in brackets and may or may not be the only text. Can anyone help?

  • How can I effectively test a scripting engine?

    - by ChaosPandion
    I have been working on an ECMAScript implementation and I am currently working on polishing up the project. As a part of this, I have been writing tests like the following: [TestMethod] public void ArrayReduceTest() { var engine = new Engine(); var request = new ExecScriptRequest(@" var a = [1, 2, 3, 4, 5]; a.reduce(function(p, c, i, o) { return p + c; }); "); var response = (ExecScriptResponse)engine.PostWithReply(request); Assert.AreEqual((double)response.Data, 15D); } The problem is that there are so many points of failure in this test and similar tests that it almost doesn't seem worth it. It almost seems like my effort would be better spent reducing coupling between modules. To write a true unit test I would have to assume something like this: [TestMethod] public void CommentTest() { const string toParse = "/*First Line\r\nSecond Line*/"; var analyzer = new LexicalAnalyzer(toParse); { Assert.IsInstanceOfType(analyzer.Next(), typeof(MultiLineComment)); Assert.AreEqual(analyzer.Current.Value, "First Line\r\nSecond Line"); } } Doing this would require me to write thousands of tests which once again does not seem worth it.

  • On Windows, how does console window ownership work?

    - by shroudednight
    When a console application is started from another console application, how does console ownership work? I see four possibilities: The second application inherits the console from the first application for its lifetime, with the console returning to the original owner on exit. Each application has its own console. Windows then somehow merges the content of the two into what the "console" visible to the user The second application get a handle to the console that belongs to the first application. The console is placed into shared memory and both applications have equal "ownership" It's quite possible that I missed something and none of these four options adequately describe what Windows does with its consoles. If the answer is close to option 4. My follow-up question is which of the two processes is responsible for managing the window? (Handling graphical updates when the screen needs to be refreshed / redrawn, etc) A concrete example: Run CMD. Then, using CMD, run [console application]. The [console application] will write to what appears to be the same console window that CMD was using.

  • Is it possible to mix MEF and Unity within a MEF-based plugin?

    - by Dave
    I'm finally diving into Unity head first, and have run into my first real problem. I've been gradually changing some things in my app from being MEF-resolved to Unity-resolved. Everything went fine on the application side, but then I realized that my plugins were not being loaded. I started to look into this issue, and I believe it's a case where MEF and Unity don't mix. Plugins are loaded by MEF, but each plugin needs to get access to the shared libraries in my application, like app preferences, logging, etc. Initially, my plugin constructor had the ImportingConstructor attribute. I then replaced it with InjectionConstructor so that Unity could resolve its shared library dependencies. But because I did that, MEF no longer loaded it! Then I used both attributes, which compiled, but then I got a composition error (MEF). I figured that this was because the constructor takes a parameter that was once resolved by a MEF Import, so I removed all parameters. As expected, now MEF was able to load my plugin, but because the constructor needs to call into the interface that was once passed in, construction fails. So now I'm at a point where I can get MEF to start to load my plugin, but can't do anything with it because the plugin relies on shared libraries that are registered with Unity. For those of you that have successfully mixed MEF and Unity, how do you go about resolving the references to the shared libraries with Unity?

  • Polynomial operations using operator overloading

    - by Vlad
    I'm trying to use operator overloading to define the basic operations (+,-,*,/) for my polynomial class but when i run the program it crashes and my computer frozes. Update3 Ok i successfully done the first two operations(+,-). Now at multiplication, after multiplying each term of the first polynomial with each of the second i want to sort the poly list descending and then if there are more than one term with the same power to merge them in only one term, but for some reason it doesn't compile because of the sort function which doesn't work. Here's what I got: polinom operator*(const polinom& P) const { polinom Result; constIter i, j, lastItem = Result.poly.end(); Iter it1, it2; int nr_matches; for (i = poly.begin() ; i != poly.end(); i++) { for (j = P.poly.begin(); j != P.poly.end(); j++) Result.insert(i->coef * j->coef, i->pow + j->pow); } sort(Result.poly.begin(), Result.poly.end(), SortDescending()); lastItem--; while (true) { nr_matches = 0; for (it1 = Result.poly.begin(); it < lastItem; it1++) { for (it2 = it1 + 1;; it2 <= lastItem; it2++){ if (it2->pow == it1->pow) { it1->coef += it2->coef; nr_matches++; } } Result.poly.erase(it1 + 1, it1 + (nr_matches + 1)); } return Result; } Also here's SortDescending: struct SortDescending { bool operator()(const term& t1, const term& t2) { return t2.pow < t1.pow; } }; What did i do wrong? Thanks!

  • jQuery Drag/Drop problem: mousemove Event not binding for some elements

    - by saturdayplace
    Using the latest jQuery/UI that are hosted at Google. I've got the following markup: <ul id="tree"> <li><a href="1/">One</a></li> <li><a href="2/">Two</a></li> </ul> And the following javascript: $(document).ready(function(){ // Droppable callbacks function dragOver(overEvent, ui_object) { $(this).mousemove(function(moveEvent){ console.log("moved over", this); }); } function drop_deactivate() { $(this).unbind(); } function drag_out() { $(this).unbind(); } // Actual dragging $("#treeContainer li").draggable({ revert: true, revertDuration: 0 }); // Actuall dropping $("a").droppable({ tolerance: "pointer", over: dragOver, deactivate: drop_deactivate, out: drag_out }); }); If I drag the first li down over the second, the mousemove function fires (and firebug logs the output). But if I drag the second li up over the first, the mousemove function doesn't fire. You can see this live at http://jsbin.com/ivala. Is there a reason for this? Should I be trapping the mousemove event in some other way? Edit: It appears as thought the mousemove() event isn't binding for earlier elements than the one currently being dragged (should be bound upon their mouseover).

  • NSMutableURLRequest wont try to use 3G when 3G is not 'connected' in Reachability enumeration

    - by Kyle
    I won't bother posting any code because my code works fine when I launch Safari or something that turns on the 3G connection first. When I put it Airport mode, then put back OFF, I will get the behavior of a connection error saying No internet connection with NSMutableURLRequest. I've personally mailed apple about how the Ant gets turned on and off, and they said anything that uses their base CFSocketStream object will turn on the Ant, and I quote: "such as NSURLRequest".. BSD Sockets do not, just so everyone knows.. However, I assumed NSMutableURLRequest would fall into the category of 'Does', but it seems like it doesnt. It never succeeds for me when I cycle Airport or have the phone idle for a long time. It will ALWAYS succeed when I open any other network app first to turn the Ant on. Shall I be forced to do a dummy NSURLRequest call to turn this on; or has anyone been able to get this class working just fine? Remember this is just an implementation of NSMutableURLRequest to upload a file Async, and no other Network operations are performed anywhere; no ads, no version checks, no nothing.

  • Cocoa NSStream works with SSL, with socks5, but not at the same time

    - by Evan D
    Upon connecting (to an FTP, at first without SSL) I run: NSArray *objects = [NSArray arrayWithObjects:@"proxy.ip", [NSNumber numberWithInt:1080], NSStreamSOCKSProxyVersion5, @"user", @"pass", nil]; NSArray *keys = [NSArray arrayWithObjects:NSStreamSOCKSProxyHostKey, NSStreamSOCKSProxyPortKey, NSStreamSOCKSProxyVersionKey, NSStreamSOCKSProxyUserKey, NSStreamSOCKSProxyPasswordKey, nil]; NSDictionary *proxyDictionary = [NSDictionary dictionaryWithObjects:objects forKeys:keys]; [iStream retain]; [iStream setDelegate:self]; [iStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; [iStream setProperty:proxyDictionary forKey:NSStreamSOCKSProxyConfigurationKey]; [iStream open]; same for iStream. This allows me to connect succesfully through a socks5 proxy. If I continue without setProperty:proxyDictionary... (socks5 disabled) I would tell the server to switch to SSL, and then successfully apply these settings to the in/output streams, thus giving me a SSL connection: NSMutableDictionary *settings = [NSMutableDictionary dictionaryWithCapacity:1]; [settings setObject:(NSString *)NSStreamSocketSecurityLevelTLSv1 forKey:(NSString *)kCFStreamSSLLevel]; // to allow selfsigned certificates: [settings setObject:[NSNumber numberWithBool:YES] forKey:(NSString *)kCFStreamSSLAllowsAnyRoot]; [iStream retain]; [iStream setDelegate:self]; [iStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode]; CFReadStreamSetProperty((CFReadStreamRef)iStream, kCFStreamPropertySSLSettings, (CFTypeRef)settings); [iStream setProperty:NSStreamSocketSecurityLevelTLSv1 forKey:NSStreamSocketSecurityLevelKey]; same for oStream. All of which works fine if I disable socks5. If I turn it on (line 7 in the first snippit) I lose contact when applying the SSL settings. If I had to guess, I'd think it's losing some properties when applying (ssl) "settings"? Please help :) Evan
