  • JavaApplicationStub with CFBundleDocumentTypes

    - by mystro
    I'm trying to use CFBundleDocumentTypes to associate a custom file extension with my application. As far as I can tell, this seems to "work" -- JavaApplicationStub launches my application when I double click the file. However, no callback is registered through the ApplicationListener events I setup in java. I used the code listed in http://stackoverflow.com/questions/1460193/set-default-file-association-mac-os-x-java-package-maker-installer to do the file association, and the file association itself appears fine, but it seems as if it is the application stub trying to launch the file, and thus fails. I added the Apple ApplicatinListener code to my java application at (similar to http://developer.apple.com/mac/library/documentation/Java/Reference/1.5.0/appledoc/api/index.html?com/apple/eawt/Application.html) but it doesn't seem like my application ever gets a call back. the code is similar to Application.getApplicatin().addApplicationListener( new ApplicationAdapter() { public void handleOpenFile(ApplicationEvent evt) { //some logging message here that I never get} }); I should perhaps mention that I'm also using SWT... Any help would be appreciated

  • Is there a way to reduce the verbosity of using String.Format(...., p1, p2, p3)?

    - by Edward Tanguay
    I often use String.Format() because it makes the building of strings more readable and manageable. Is there anyway to reduce its syntactical verbosity, e.g. with an extension method, etc.? Logger.LogEntry(String.Format("text '{0}' registered", pair.IdCode)); public static void LogEntry(string message) { ... } e.g. I would like to use all my and other methods that receive a string the way I use Console.Write(), e.g.: Logger.LogEntry("text '{0}' registered", pair.IdCode);

  • recv receiving not whole data sometime

    - by milo
    hi all, i have following issue: here is the chunk of code: void get_all_buf(int sock, std::string & inStr) { int n = 1; char c; char temp[1024*1024]; bzero(temp, sizeof(temp)); n = recv(sock, temp, sizeof(temp), 0); inStr = temp; }; but sometimes recv returning not whole data (data length always less then sizeof(temp)), only it's part. write side always sends me whole data (i got it with sniffer). what matter? thx. P.S. i know, good manner suggests me to check n (if (n < 0) perror ("error while receiving data), but it doesn't matter now - it's not reason of my problem. P.S.2 i've forgot - it's blocking socket.

  • Combining RequiresSTA and Timeout attributes on a test fails

    - by Peter Lillevold
    I have a test that opens and closes a WPF Window and thus requires the STA threading apartment. To safeguard the test against the window staying open (and thus hang the test indefinitely) I wanted to use the Timeout attribute. The problem is that applying the Timeout attribute causes the test to fail on timeout regardless of whether the test works or not. Without the attribute everything works fine. My theory is that Timeout causes the test to be executed on a new thread that does not inherit the STA apartment. Is there another way to have both STA and the timeout safeguard in NUnit? My test looks something like this: [Test, RequiresSTA, Timeout(300)] public void Construct() { var window = new WindowView(); window.Loaded += (sender, args) => window.Close(); var app = new Application(); app.Run(window); try { // ...run system under test } finally { app.Shutdown(); } }

  • Passing Global Variable value to Facebook - Gets NULL only

    - by Viral
    hi all friends, I am making a game application in that I want to pass my score on wall of face book. I've completed all the things (the log in and message passing part) but when I passes the score via global variable, I am getting only null as a value and not the score that I want. Is there any way to pass data or string to Face book and write on a wall? My code is (void)viewDidLoad { static NSString* kApiKey = @"be60415be308e2b44c0ac1db83fe486b"; static NSString* kApiSecret = @"4f880c7e100321f808c41b1d3c813dfa"; _session = [[FBSession sessionForApplication:kApiKey secret:kApiSecret delegate:self] retain]; score = [NSString stringWithFormat:@"%@",appDelegate.myTextView]; [_session resume]; [super viewDidLoad]; } whre score is NSString and myTextView is NSString in other viewcontrollerfile, And appDelegate is global variable. Any help?? thanks in advance.

  • Generics limitation, or lack of skillz ?

    - by Two Shoes
    I want to define the following class as such: public class CollectionAttribute<E extends Collection<T>> { private String name; private E value; public CollectionAttribute(String name, E value) { this.name = name; this.value = value; } public E getValue() { return value; } public void addValue(T value) { value.add(T); } } This won't compile (cannot resolve symbol T). If I replace the class declaration with the following: public class CollectionAttribute<E extends Collection<?>> Then I can't reference the parametrized type of the collection. Am I missing something or have I reached a limitation with generics in Java ?

  • Re-ordering a collection of UIView's based on their CGPoint

    - by Chris
    Hi all, I have a NSMutableArray that holds a collection of UIViewControllers Amongst other properties and methods an instance of each of the viewControllers are placed in a parent view The user will place these objects individually when desired to. So essentially I use - (void)addSubview:(UIView *)view when a new view is added to the parent view controller. Because the UI is isometric it's made things a tad more complicated What I am trying to do is re-order the views based on their co-ordinate position, so items higher up the parent UIView frame is indexed lower then views lower in the parent UIview frame. And items that are on the left side of the view are positioned at a higher index to those on the right I think the solution may have to do with re-ordering the NSMutableArray but how can I compare the CGpoints? Do I need to compare the x and y separately?

  • Get first character of each word and its position in a sentence/paragraph

    - by Radhika
    I am trying to create a map by taking the first character of each word and it's position in a sentence/paragraph. I am using regex pattern to achieve this. Regex is a costly operation. Are there are any ways to achieve this? Regex way: public static void getFirstChar(String paragraph) { Pattern pattern = Pattern.compile("(?<=\\b)[a-zA-Z]"); Map newMap = new HashMap(); Matcher fit = pattern.matcher(paragraph); while (fit.find()) { newMap.put((fit.group().toString().charAt(0)), fit.start()); } }

  • How can I modify an Android bitmap in C++ (JNI/NDK) so that I can use on the Java side?

    - by HardCoder
    I call a C++ function over JNI and pass a RGBA_8888 bitmap, lock it, change the values, unlock it, return and then display it in Java with this C++ code: AndroidBitmap_getInfo(env, map, &info) < 0); AndroidBitmap_lockPixels(env, map, (void**)&pixel); for(i=info.width*info.height-1;i>=0;i--) { pixel[i] = 0xf1f1f1f1; } AndroidBitmap_unlockPixels(env, map); The problem I have is that the bitmaps looks not as I expect it and the pixel values (verified with getPixel) are not the same when I check them in Java from what I set them in C++. When I set the bitmap values to 0xffffffff I get the correct value in Java, but for many others I don't. 0xf1f1f1f1 for example turns into 0xF1FFFFFF. What do I have to do to make it work ? PS: I am using Android 2.3.4

  • Wrapping pre-made elements using GWT?

    - by user246114
    Hi, I've been working with GWT for awhile, I can't find a way to integrate it with a preexisting website which is a real downer. My page content is already generated for me using jsp, like: <div id='A'></div> <div id='B'></div> etc. there is no way for me to do something like this though: public void onModuleLoad() { SimplePanel spA = new SimplePanel( Document.getElementById("A")); spA.add(new Label("hello")); SimplePanel spB = new SimplePanel( Document.getElementById("B")); spB.setWidth("200px"); etc .. } seems like there's no way to just wrap a pre-existing element. Is this true, or am I missing how to do this? I need be able to wrap a bunch of elements like this, to manipulate them later on. I see TextBox, Button, a few other classes have wrap() methods, however nothing like that exists for elements, Thanks

  • c# passing method names as the argument in a method

    - by Alan Bennett
    hi guys, I have a recuring method which shows up many times in my code its basically checking to make sure that the connection to the odbc is ok and then connects but each time this method is called it calls another method and each instance of the main method this one is different, as each method is about 8 lines of code having it 8 times in the code isnt ideal. so basically i would like to have just one method which i can call passing the name of the new method as an arguement. so basically like: private void doSomething(methodToBeCalled) { if(somthingistrue) { methodToBeCalled(someArgument) } } is this possible? thanks in advance

  • Help with IE bugs when writing JSON via an ASPX response

    - by Jereme
    I have an ASPX page that I am using to write JSON. It works great in Firefox and Chrome, but when I try and use it in IE 8 it gives me an "The XML page cannot be displayed" error instead of allowing jQuery to load the JSON being written by the response. Any ideas? Here is what my code looks like: protected override void OnLoad(EventArgs e) { Response.Clear(); Response.ClearHeaders(); Response.ContentType = "application/json"; Response.Cache.SetCacheability(HttpCacheability.NoCache); Response.Write(string.Format("[ {{ \"Foo\": \"{0}\", \"bar\": \"{1}\" }} ]", "Foo Content", "Bar Content")); Response.End(); }

  • C# Events and Lambdas, alternative to null check?

    - by Eugarps
    Does anybody see any drawbacks? It should be noted that you can't remove anonymous methods from an event delegate list, I'm aware of that (actually that was the conceptual motivation for this). The goal here is an alternative to: if (onFoo != null) onFoo.Invoke(this, null); And the code: public delegate void FooDelegate(object sender, EventArgs e); public class EventTest { public EventTest() { onFoo += (p,q) => { }; } public FireFoo() { onFoo.Invoke(this, null); } public event FooDelegate onFoo; }

  • StreamTokenizer Iterator Adapter help

    - by alpdog14
    I have this StreamTokenizer Iterator Adapter that is suppose to create a Tokenizer Iterator Index Builder then build the index from a STIA wrapped around a StreamTokenizer. I am having trouble implementing the hasNext and Next for my STIA, can anyone help me, here is my class: public class StreamTokenizerIteratorAdapter implements Iterator<Token> { DefaultIndexImpl index; StreamTokenizer source; public StreamTokenizerIteratorAdapter(final StreamTokenizer source) { if (source == null) throw new IllegalArgumentException("source == null"); } @Override public boolean hasNext() { return !index.isEmpty(); } public Token next() { if(!index.isEmpty()) return next(); else return null; } @Override public void remove() { throw new UnsupportedOperationException(); } } Should I be using the source element in the hasNext() and next()?

  • Structuremap Configuration with generics

    I have IRepository interface with which i want to use NHibernateRepository. How do i configure it with structure map? protected void ConfigureDependencies() { ObjectFactory.Initialize( x => { x.For<ILogger>().Use<Logger>(); x.For<IRepository<T>>().Use<NHibernateRepository<T>>(); } ); } I m getting an error on T. Another question I have is if it s OK to make an ApplicationContext static class, configure it with structure map and provide instances with it? I have read that static classes are bad, but I dont want to initialize the ApplicationContext class that I have the injections everywhere. What s the best practice for this? Thanks.

  • Floating point precision nuances.

    Hi, I found this code in NVIDIA's cuda SDK samples. void computeGold( float* reference, float* idata, const unsigned int len) { reference[0] = 0; double total_sum = 0; unsigned int i; for( i = 1; i < len; ++i) { total_sum += idata[i-1]; reference[i] = idata[i-1] + reference[i-1]; } // Here it should be okay to use != because we have integer values // in a range where float can be exactly represented if (total_sum != reference[i-1]) printf("Warning: exceeding single-precision accuracy. Scan will be inaccurate.\n"); } (C) Nvidia Corp Can somebody please tell me a case where the warning would be printed, and most importantly, why. Thank you very much.

  • ASP.NET web services leak memory when (de)serializing disposable objects?

    - by Serilla
    In the following two cases, if Customer is disposable (implementing IDisposable), I believe it will not be disposed by ASP.NET, potentially being the cause of a memory leak: [WebMethod] public Customer FetchCustomer(int id) { return new Customer(id); } [WebMethod] public void SaveCustomer(Customer value) { // save it } This flaw applies to any IDisposable object. So returning a DataSet from a ASP.NET web service, for example, will also result in a memory leak - the DataSet will not be disposed. In my case, Customer opened a database connection which was cleaned up in Dispose - except Dispose was never called resulting in loads of unclosed database connections. I realise there a whole bunch of bad practices being followed here (its only an example anyway), but the point is that ASP.NET - the (de)serializer - is responsible for disposing these objects, so why doesn't it? This is an issue I was aware of for a while, but never got to the bottom of. I'm hoping somebody can confirm what I have found, and perhaps explain if there is a way of dealing with it.

  • How to pass around event as parameter in c#

    - by Jerry Liu
    Am writing unit test for a multi-threading application, where I need to wait until a specific event triggered so that I know the asyn operation is done. E.g. When I call repository.add(something), I wait for event AfterChange before doing any assertion. So I write a util function to do that. public static void SyncAction(EventHandler event_, Action action_) { var signal = new object(); EventHandler callback = null; callback = new EventHandler((s, e) => { lock (signal) { Monitor.Pulse(signal); } event_ -= callback; }); event_ += callback; lock (signal) { action_(); Assert.IsTrue(Monitor.Wait(signal, 10000)); } } However, the compiler prevents from passing event out of the class. Is there a way to achieve that?

  • How to scroll the content without scrolling the image in the background using UIScrollView ?

    - by Raymond Choong
    I am trying to scroll the content without scrolling the image in the background using UIScrollView. I am using IB and setting the FileOwner View to point to the Scroll View (Image View is a child of the Scroll view). I have made the image height to be 960 pixels. I have also set scrolling content size in the vierController that owns this UIView (void)viewDidLoad { UIScrollView *tempScrollView = (UIScrollView *)self.view; tempScrollView.contentSize=CGSizeMake(320, 960); } My problem is that the Image only appears moves along with the content. I have tried taking out the settings in viewDidLoad, but the scrolling cease to function. I have also tried changing the location of the image and have it placed under VIEW instead of Scoll View (by the way Scroll View is a child of VIEW), but that resulted in the app breaking (termination error). Any advice would be appreciated.
