  • Was delegates static by default?

    - by Sri Kumar
    Hello All, I was just trying to understand delegates using the following code. public class delegatesEx { public delegate int Mydelegate(int first, int second); public int add(int first, int second) { return first + second; } public int sub(int first, int second) { return first - second; } } Here is my main method Console.WriteLine("******** Delegates ************"); delegatesEx.Mydelegate myAddDelegates = new delegatesEx.Mydelegate(new delegatesEx().add); int addRes = myAddDelegates(3, 2); Console.WriteLine("Add :" + addRes); delegatesEx.Mydelegate mySubDelegates = new delegatesEx.Mydelegate(new delegatesEx().sub); int subRes = mySubDelegates(3, 2); Console.WriteLine("Sub :" + subRes); I didn't declare delegate to be static but i was able to access it using the Class name. How is it possible?

  • Determine when a NSOpenPanel will close

    - by Martin
    I'm trying to determine when an NSOpenPanel is closing before it actually closes. I need to do this so I can overlay another window with a screenshot of the open panel on top of it to be animated. Unfortunately, all the notifications that you seem to be able to access seem to fire AFTER the window's already been closed. This leads to a jarring stutter before you start your transition. I've tried: - using NSWindow delegate methods on the open panel (apparently, none of the NSWindow delegate methods work) - monitoring panel:userEnteredFilename:confirmed: (not called) - showing the dialog with a callback (callback happens AFTER the panel disappears)

  • How to get cell text based on indexPath?

    - by Sheehan Alam
    I have a UITabBarController with more than 5 UITabBarItems so the moreNavigationController is available. In my UITabBarController Delegate I do the following: - (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController { //do some stuff //... UITableView *moreView = (UITableView *)self.tabBarController.moreNavigationController.topViewController.view; moreView.delegate = self; } I want to implement a UITableViewDelegate so I can capture the row that was selected, set a custom view property and then push the view controller: - (void)tableView:(UITableView *)tblView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { //how can I get the text of the cell here? } I need to get the text of a cell when the user taps on a row. How can I accomplish this?

    I am sending a Post with object loader and getting this error in output window. FYI, My didFailWithError: delegate never got hit. Not sure why. `objectLoader:didFailWithError:]:` unrecognized selector `sent to class 0x123608` How did i find out what is 0x123608? I set the router in AppDelegate class and Mapping in AppDelegate too. here is a method in my class which inherit RKObjectLoaderDelegate. I am using shared singleton.

  • Can an asynchronously fired event run synchronously on a form?

    - by cyclotis04
    [VS 2010 Beta with .Net Framework 3.5] I've written a C# component to asynchronously monitor a socket and raise events when data is received. I set the VB form to show message boxes when the event is raised. What I've noticed is that when the component raises the event synchronously, the message box blocks the component code and locks the form until the user closes the message. When it's raised asynchronously, it neither blocks the code, nor locks the form. What I want is a way to raise an event in such a way that it does not block the code, but is called on the same thread as the form (so that it locks the form until the user selects an option.) Can you help me out? Thanks. [Component] using System; using System.Threading; using System.ComponentModel; namespace mySpace { public delegate void SyncEventHandler(object sender, SyncEventArgs e); public delegate void AsyncEventHandler(object sender, AsyncEventArgs e); public class myClass { readonly object syncEventLock = new object(); readonly object asyncEventLock = new object(); SyncEventHandler syncEvent; AsyncEventHandler asyncEvent; private delegate void WorkerDelegate(string strParam, int intParam); public void DoWork(string strParam, int intParam) { OnSyncEvent(new SyncEventArgs()); AsyncOperation asyncOp = AsyncOperationManager.CreateOperation(null); WorkerDelegate delWorker = new WorkerDelegate(ClientWorker); IAsyncResult result = delWorker.BeginInvoke(strParam, intParam, null, null); } private void ClientWorker(string strParam, int intParam) { Thread.Sleep(2000); OnAsyncEvent(new AsyncEventArgs()); OnAsyncEvent(new AsyncEventArgs()); } public event SyncEventHandler SyncEvent { add { lock (syncEventLock) syncEvent += value; } remove { lock (syncEventLock) syncEvent -= value; } } public event AsyncEventHandler AsyncEvent { add { lock (asyncEventLock) asyncEvent += value; } remove { lock (asyncEventLock) asyncEvent -= value; } } protected void OnSyncEvent(SyncEventArgs e) { SyncEventHandler handler; lock (syncEventLock) handler = syncEvent; if (handler != null) handler(this, e, null, null); // Blocks and locks //if (handler != null) handler.BeginInvoke(this, e, null, null); // Neither blocks nor locks } protected void OnAsyncEvent(AsyncEventArgs e) { AsyncEventHandler handler; lock (asyncEventLock) handler = asyncEvent; //if (handler != null) handler(this, e, null, null); // Blocks and locks if (handler != null) handler.BeginInvoke(this, e, null, null); // Neither blocks nor locks } } } [Form] Imports mySpace Public Class Form1 Public WithEvents component As New mySpace.myClass() Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click component.DoWork("String", 1) End Sub Private Sub component_SyncEvent(ByVal sender As Object, ByVal e As pbxapi.SyncEventArgs) Handles component.SyncEvent MessageBox.Show("Synchronous event", "Raised:", MessageBoxButtons.OK) End Sub Private Sub component_AsyncEvent(ByVal sender As Object, ByVal e As pbxapi.AsyncEventArgs) Handles component.AsyncEvent MessageBox.Show("Asynchronous event", "Raised:", MessageBoxButtons.OK) End Sub End Class

  • Objective-C - Unloading loaded view when it is swapped

    - by teepusink
    Hi, What is the best way to do view management in a multiview application? Right now I have this ViewSwitcher method/function that comes from a custom delegate I created. The code is a whole bunch of if else like this MyViewController *c = [[MyViewController alloc] initWithNibName:@"MyViewController" bundle:nil]; c.delegate = self; self.myViewController = c; [self.viewHolder insertSubview:c.view atIndex:0]; [c release]; That works fine, but when I visited the function a second time, is there going to be 2 instances of MyViewController now or just 1? How do I unload MyViewController when I switch to another view? Or is there a better way to manage my views? Thanks, Tee

  • Error message when trying to insert method into touchesBegan

    - by Rob
    I am trying to create a new method within my TapDetectingImageView file and it's giving me a warning that it cannot find the method even though I have it declared in the .h file. The specific three warnings all point to the @end line in the .m file when I build it and they say: "Incomplete implementation of class 'TapDetectingImageView' ; 'Method definition for '-functionA:' not found" ; "Method definition for '-functionB:' not found" What am I missing? Am I not allowed to do this in a protocol file like TapDetectingImageView? In my .h file is: @interface TapDetectingImageView : UIImageView <AVAudioPlayerDelegate> { id <TapDetectingImageViewDelegate> delegate; } @property (nonatomic, assign) id <TapDetectingImageViewDelegate> delegate; -(void) functionA:(NSString*)aVariable; -(void) functionB:(NSString*)aVariable; @end In my .m file is: -(void)functionA:(NSString*)aVariable { // do stuff in this function with aVariable } -(void)functionB:(NSString*)aVariable { // do stuff in this function with aVariable }

  • Race condition for thread startup

    - by Ozzah
    A similar question was asked here, but the answers generally all seem to relate to the lambda notation. I get a similar result without the lambda so I thought I'd ask for some clarification: Say I have something like this: for (int i = 0; i < 5; i++) (new Thread(new ThreadStart(delegate() { Console.WriteLine("Thread " + i); }))).Start(); One would expect the following output: Thread 0 Thread 1 Thread 2 Thread 3 Thread 4 Now I realise that the threads aren't started in any particular order, so let's just assume that the above lines can come out in any order. But that is not what happens. What instead happens: Thread 3 Thread 4 Thread 4 Thread 4 Thread 4 or something similar, which leads me to believe that rather than passing the value if i, it is passing the reference. (Which is weird, since an int is a value type). Doing something like this: for (int i = 0; i < 5; i++) (new Thread(new ThreadStart(delegate() { int j = i; Console.WriteLine("Thread " + j); }))).Start(); does not help either, even though we have made a copy of i. I am assuming the reason is that it hasn't made a copy of i in time. Doing something like this: for (int i = 0; i < 5; i++) { (new Thread(new ThreadStart(delegate() { Console.WriteLine("Thread " + i); }))).Start(); Thread.Sleep(50); } seems to fix the problem, however it is extremely undesirable as we're wasting 50ms on each iteration, not to mention the fact that if the computer is heavily loaded then maybe 50ms may not be enough. Here is a sample with my current, specific problem: Thread t = new Thread(new ThreadStart(delgate() { threadLogic(param1, param2, param3, param4); })); t.Start(); param1 = param2 = param3 = param4 = null; with: void threadLogic(object param1, object param2, object param3, object param4) { // Do some stuff here... } I want threadLogic() to run in its own thread, however the above code gives a null reference exception. I assume this is because the values are set to null before the thread has had a chance to start. Again, putting a Thread.Sleep(100) works, but it is an awful solution from every aspect. What do you guys recommend for this particular type of race condition?

  • Need help understanding .net ThreadPool

    - by Meredith
    I am trying to understand what ThreadPool does, I have this .NET example: class Program { static void Main() { int c = 2; // Use AutoResetEvent for thread management AutoResetEvent[] arr = new AutoResetEvent[50]; for (int i = 0; i < arr.Length; ++i) { arr[i] = new AutoResetEvent(false); } // Set the number of minimum threads ThreadPool.SetMinThreads(c, 4); // Enqueue 50 work items that run the code in this delegate function for (int i = 0; i < arr.Length; i++) { ThreadPool.QueueUserWorkItem(delegate(object o) { Thread.Sleep(100); arr[(int)o].Set(); // Signals completion }, i); } // Wait for all tasks to complete WaitHandle.WaitAll(arr); } } Does this run 50 "tasks", in groups of 2 (int c) until they all finish? Or I am not understanding what it really does.

  • Why do we need the "event" keyword while defining events ?

    - by Puneet Dudeja
    I don't understand why do we need the "event" keyword while defining events, when we can do the same thing without using "event" keyword, just by using the delegates. e.g. public delegate void CustomEventHandler(int a, string b); public event CustomEventHandler customEvent; customEvent += new CustomEventHandler(customEventHandler); customEvent(1,"a"); // Raising the event Here if I remove the "event" keyword from the second line, then also I can raise the event by invoking the delegate. Can anybody please tell me why is this event keyword needed ?

  • Using ManualResetEvent to wait for multiple Image.ImageOpened events

    - by umlgorithm
    Dictionary<Image, ManualResetEvent> waitHandleMap = new Dictionary<Image, ManualResetEvent>(); List<Image> images = GetImagesWhichAreAlreadyInVisualTree(); foreach (var image in images) { image.Source = new BitmapImage(new Uri("some_valid_image_url")); waitHandleMap.Add(image, new ManualResetEvent(false)); image.ImageOpened += delegate { waitHandleMap[image].Set(); }; image.ImageFailed += delegate { waitHandleMap[image].Set(); }; } WaitHandle.WaitAll(waitHandleMap.Values.ToArray()); WaitHandle.WaitAll blocks the current UI thread, so ImageOpened/ImageFailed events would never get fired. Could you suggest me an easy workaround to wait for the multiple ui events?

  • Call AppDelegate Method from Class

    - by golfromeo
    Basically, I need to call a method in my AppDelegate from one of my view controller classes. Currently, I'm doing the following: myAppDelegate *appDelegate = (myAppDelegate *)[[UIApplication sharedApplication] delegate]; [appDelegate doMethod]; And including the myAppDelegate.h at the top of the .m file of the class: #import "myAppDelegate.h" When I run it, everything works... But I get the following warning: warning 'myAppDelegate' may not respond to '-doMethod' Is there another way that I should reference the app delegate? Thanks for any help in advance.

  • My UITabBarController isn't appearing, but its first view is?

    - by E-Madd
    I've done some reorganizing of my project recently and now I'm not seeing my tab bar controller, but its first view controller's view is appearing. Here's a breakdown of everything that happens prior to the problem. App Delegate loads FirstViewController with nib. FirstViewController loads the application data from my server and then presents MainViewController with a modal transition. MainViewController is where the UITabBarController is supposed to be appearing. It's a very simple class. The .h @interface MainViewController : UIViewController <UITabBarControllerDelegate> { IBOutlet UITabBarController *tabBarController; } @property (nonatomic, retain) UITabBarController *tabBarController; @end The .m @implementation MainViewController @synthesize tabBarController; - (void)viewDidLoad { NSLog(@"MainViewController viewDidLoad"); //set tab bar controller delegate to self tabBarController.delegate = self; // home view HomeViewController *home = [[HomeViewController alloc] initWithTab]; // menu view MenuViewController *menu = [[MenuViewController alloc] initWithTab]; // special offers view SpecialOffersViewController *so = [[SpecialOffersViewController alloc] initWithTab]; // events view EventsViewController *events = [[EventsViewController alloc] initWithTab]; // info view InfoViewController *info = [[InfoViewController alloc] initWithTab]; //populate the tab bar controller with view controllers NSArray *controllers = [NSArray arrayWithObjects:home, menu, so, events, info, nil]; tabBarController.viewControllers = controllers; //release view controllers [home release]; [menu release]; [so release]; [events release]; [info release]; [controllers release]; //add tab bar controller to view [self.view addSubview:tabBarController.view]; [super viewDidLoad]; } and here's the bit from FirstViewController that modally presents the MainViewController... MainViewController *controller = [[MainViewController alloc] initWithNibName:@"MainViewController" bundle:nil]; controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:controller animated:YES]; [controller release]; I'm not getting any compiler errors or warnings and the app runs swell... no crashing. It just isn't showing the darned TabBar, and it used to when I was creating it on my AppDelegate. I checked everything in my NIB and my outlets seem to be hooked up ok. I have no idea what's happened. Help!

  • Core Plot: x-axis labels not plotted when using scaleToFitPlots

    - by AlexR
    Problem: I can't get Core Plot (1.1) to plot automatic labels for my x-axis when using autoscaling ([plotSpace scaleToFitPlots:[graph allPlots]). What I have tried: I changed the values for the offsets and paddings, but this did not change the result. However, when turning autoscale off (not using [plotSpace scaleToFitPlots:[graph allPlots]]and setting the y scale automatically, the automatic labeling of the x-axis works. Question: Is there a bug in Core Plot or what did I do wrong? I would appreciate any help! Thank you! This is how I have set up my chart: CPTBarPlot *barPlot = [CPTBarPlot tubularBarPlotWithColor:[CPTColor blueColor] horizontalBars:NO]; barPlot.baseValue = CPTDecimalFromInt(0); barPlot.barOffset = CPTDecimalFromFloat(0.0f); // CPTDecimalFromFloat(0.5f); barPlot.barWidth = CPTDecimalFromFloat(0.4f); barPlot.barCornerRadius = 4; barPlot.labelOffset = 5; barPlot.dataSource = self; barPlot.delegate = self; graph = [[CPTXYGraph alloc]initWithFrame:self.view.bounds]; self.hostView.hostedGraph = graph; graph.paddingLeft = 40.0f; graph.paddingTop = 30.0f; graph.paddingRight = 30.0f; graph.paddingBottom = 50.0f; [graph addPlot:barPlot]; graph.plotAreaFrame.masksToBorder = NO; graph.plotAreaFrame.cornerRadius = 0.0f; graph.plotAreaFrame.borderLineStyle = borderLineStyle; double xAxisStart = 0; CPTXYAxisSet *xyAxisSet = (CPTXYAxisSet *)graph.axisSet; CPTXYAxis *xAxis = xyAxisSet.xAxis; CPTMutableLineStyle *lineStyle = [xAxis.axisLineStyle mutableCopy]; lineStyle.lineCap = kCGLineCapButt; xAxis.axisLineStyle = lineStyle; xAxis.majorTickLength = 10; xAxis.orthogonalCoordinateDecimal = CPTDecimalFromDouble(yAxisStart); xAxis.paddingBottom = 5; xyAxisSet.delegate = self; xAxis.delegate = self; xAxis.labelOffset = 0; xAxis.labelingPolicy = CPTAxisLabelingPolicyAutomatic; [plotSpace scaleToFitPlots:[graph allPlots]]; CPTMutablePlotRange *yRange = plotSpace.yRange.mutableCopy; [yRange expandRangeByFactor:CPTDecimalFromDouble(1.3)]; plotSpace.yRange = yRange; NSInteger xLength = CPTDecimalIntegerValue(plotSpace.xRange.length) + 1; plotSpace.xRange = [CPTPlotRange plotRangeWithLocation:CPTDecimalFromDouble(xAxisStart) length:CPTDecimalFromDouble(xLength)] ;

  • Custom business object comparer

    - by gruber
    Hello, I need to implement mechanism that compares two business objects and return the list of differences (past value, new value, isDifferenceBetter). Because not all fields of class has to be compared and one fields need to be compared with different function then the other (sometimes < is better sometimes is better ... ) I figured out that I need to implelemnt custom attribute and give it to each field that has to be compared in this object. This attribute must have: - name - delegate or sth to point to the function which would be applied for comparision (dont know how to do it so far) So could anyone suggest me if its a good idea? Maybe any other ideas. Using attributes I would be able to use refflection to iterate through each field with attribute and invoke needed delegate. thanks for help bye

  • 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; }

  • How to call a function though Control.BeginInvoke in a signal-slot-like fashion?

    - by Dimitri C.
    I'd like a delegate that calls a function in a different thread when it is invoked. Currently, I'm using the following implementation: delegate void someFunctionDelegate(); //... someFunctionDelegate callBackFunction = someForm.SomeFunction; someForm.Invoke(someFunctionDelegate); However, I'd like a more compact form, combining both the someForm instance and the SomeForm.SomeFunction member function. I'm thinking of something like this: var callBackFunction = new AsynchronousCrossThreadDelegate(someForm, SomeForm.SomeFunction); callBackFunction(); // Should call someForm.BeginInvoke(SomeForm.SomeFunction); Is there a way to do so in C#/.NET? Update I'm looking for a solution that will work for functions with 0 or more parameters.

  • cocoa - referencing a method on the parent

    - by Mike
    I had a method on my main view controller named "calculateThis". This method was run, obviously, as int newValue = [self calculateThis:myVariable]; when I run it from inside the view controller. Then I created a static class and I need to run this method from there. How do I reference this method from that class using just relative references, as super, superview, delegate, etc. I cannot use the class name defined on the delegate because this static class is used in several apps of mine.

  • UITableViewController setting delegates and datasource

    - by the_great_monkey
    Hi iOS gurus, I'm a little bit confused about UITableViewController... As far as I concern they are typically the delegate and datasource of the UITableView (although it can be made such that they are different). However in some cases, like when embedding a UITableViewController in a UITabBarViewController in Interface Builder, we initiate our table view controller in IB. Therefore in my understanding, the default initialiser is being called. But in this case, I have this piece of code: @interface Settings : UITableViewController { } And in the IB I see that the delegate and datasource of the UITableView is hooked up to this class. My question is, why is it that we don't need to explicitly say that it is following: @interface Settings : UITableViewController <UITableViewDelegate, UITableViewDataSource> { } And in the .m file: - (void)viewDidLoad { [super viewDidLoad]; [tableView setDelegate:self]; [tableView setDataSource:self]; } I have indeed stumbled upon some cases where I have to explicitly code the above a few times to make something work. Although it is still a mystery for me as of why it is needed...

  • Creating Delegates With Lambda Expressions in F#

    Why does... type IntDelegate = delegate of int -> unit type ListHelper = static member ApplyDelegate (l : int list) (d : IntDelegate) = l |> List.iter (fun x -> d.Invoke x) ListHelper.ApplyDelegate [1..10] (fun x -> printfn "%d" x) not compile, when: type IntDelegate = delegate of int -> unit type ListHelper = static member ApplyDelegate (l : int list, d : IntDelegate) = l |> List.iter (fun x -> d.Invoke x) ListHelper.ApplyDelegate ([1..10], (fun x -> printfn "%d" x)) does? The only difference that is that in the second one, ApplyDelegate takes its parameters as a tuple. Error 1 This function takes too many arguments, or is used in a context where a function is not expected

  • Registering a piece of script across all the SharePoint Pages

    - by NLV
    Hello all I've a business requirement in which i need to create a SharePoint feature which registers a JavaScript across all the SharePoint pages. The only way i figured out to achieve it is that adding the script in (all) the SharePoint Master Pages or any other custom master pages present in the Site/Site Collection/Web Application while activating the feature. But i found that editing the master pages to add a Javascript snippet is not feasible. Finally i found that i could register my custom controls in the "Delegate Controls" and the custom user control i created can in turn register my script in the page. But my question is how can i handle it if the master page does not have a delegate control? Or is there any other possible solution to register a script across all the SharePoint pages?
