  • Only the last node moves when multiple nodes are called for action

    - by Kriem
    Of the three parts I want to move, only the last one actually moves. I can't seem to "recycle" the ease action I created. How is this done the correct way? - init { // initial setup [self moveParts]; } - (void)moveParts { id action = [CCMoveBy actionWithDuration:1 position:ccp(0,160)]; id ease = [CCEaseInOut actionWithAction:action]; [part1 runAction:ease]; [part2 runAction:ease]; [part3 runAction:ease]; }

  • Is it possible to have a variadic function in C with no non-variadic parameter?

    - by Tim
    I have the following function: void doStuff(int unusedParameter, ...) { va_list params; va_start(params, unusedParameter); /* ... */ va_end(params); } As part of a refactor, I'd like to remove the unused parameter without otherwise changing the implementation of the function. As far as I can tell, it's impossible to use va_start when you don't have a last non-variadic parameter to refer to. Is there any way around this? Background: It is in fact a C++ program, so I could use some operator-overloading magic as suggested here, but I was hoping not to have to change the interface at this point. The existing function does its work by requiring that the variable argument list be null-terminated, and scanning for the NULL, therefore it doesn't need a leading argument to tell it how many arguments it has.

  • Function argument treated as undeclared

    - by Mikulas Dite
    I've prepared this simple example which is not working for me #include <stdio.h> #include <stdlib.h> FILE *fp; char filename[] = "damy.txt"; void echo (char[] text) { fp = fopen(filename, "a"); fwrite(text, 1, strlen(text), fp); fclose(fp); printf(text); } int main () { echo("foo bar"); return 0; } It's supposed to write both to command window and to file. However, this gives compilation error - the text used in echo() is not declared. Does c need another declaration of the variable?

    I had to do an update in my WebView from the Appdelegate.m I try it like this: [self performSelectorOnMainThread:@selector(loadWebViewWithContent:) withObject:requestObj waitUntilDone:NO]; The loadWebViewWithContent Method works great from ViewController.m, but not from the Appdelegate. I allready wrote this in my Appdelegate.h: -(void)loadWebViewWithContent:(NSURLRequest *)requestObj; Whats wrong? Please help me. I´m still a big Noob in IOS.

  • Generate a Constant expression from a function

    - by Lee
    For my Google Wave robot, on the onDocumentChanged event I want to apply a filter as follows: @Capability(filter = FILTER) @Override public void onDocumentChanged(DocumentChangedEvent event) { ... } I want the filter to be generated the first time the robot is run, which I'm trying to do as follows: private static final String FILTER = generateFilter(); private static final String generateFilter(){ ... } However, it complains FILTER isn't a constant expression when used within @Capability. generateFilter() will return the same string every time it is called, I'm only using it to create the string so that when I make changes, I don't need to worry about updating the filter. Now I could be going about this all wrong, so wondered if anyone knew what I'm doing wrong, or knew a better way in which I could generate a constant expression from the function.

  • databinding to self without code

    - by jcollum
    I'm building a UserControl in WPF. The control has two properties, Title and Description, that I'd like to bind to two textblocks. Seems real straightforward, and I got it working, but I'm curious about something. To get it to work I had to add this code: void CommandBlock_Loaded(object sender, RoutedEventArgs e) { this.DataContext = this; } My bindings look like this: <TextBlock Text="{Binding Title}" Width="100" ... /> <TextBlock Text="{Binding Description}" Width="100" ... /> What I'm wondering is how come I couldn't get it to work without the this.DataContext = this; and instead use DataContext="{Binding RelativeSource={RelativeSource Self}}" (in the UserControl element of the markup)? I'm sure I'm missing something about DataContexts but don't know what.

  • Background audio not working in windows 8 store / metro app

    - by roryok
    I've tried setting background audio through both a mediaElement in XAML <MediaElement x:Name="MyAudio" Source="Assets/Sound.mp3" AudioCategory="BackgroundCapableMedia" AutoPlay="False" /> And programmatically async void setUpAudio() { var package = Windows.ApplicationModel.Package.Current; var installedLocation = package.InstalledLocation; var storageFile = await installedLocation.GetFileAsync("Assets\\Sound.mp3"); if (storageFile != null) { var stream = await storageFile.OpenAsync(Windows.Storage.FileAccessMode.Read); _soundEffect = new MediaElement(); _soundEffect.AudioCategory = AudioCategory.BackgroundCapableMedia; _soundEffect.AutoPlay = false; _soundEffect.SetSource(stream, storageFile.ContentType); } } // and later... _soundEffect.Play(); But neither works for me. As soon as I minimise the app the music fades out

  • An Exception occur in Tablayout.

    I wanna add three layout in a TabActivity, but it was force closed when I ran it. Here is the code: import android.app.TabActivity; import android.content.res.Resources; import android.os.Bundle; import android.widget.TabHost; public class Test1 extends TabActivity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Resources res = getResources(); TabHost tabHost = getTabHost(); tabHost.addTab(tabHost.newTabSpec("egcquery").setIndicator("EGCQuery").setContent(R.layout.main1)); tabHost.addTab(tabHost.newTabSpec("PatientInfo").setIndicator("PatientInfo").setContent(R.layout.main2)); tabHost.addTab(tabHost.newTabSpec("Comp_Interp").setIndicator("Comp_Interp").setContent(R.layout.main3)); } }

  • Forward declaring an enum in c++

    - by szevvy
    Hi guys, I'm trying to do something like the following: enum E; void Foo(E e); enum E {A, B, C}; which the compiler rejects. I've had a quick look on Google and the consensus seems to be "you can't do it", but I can't understand why. Can anyone explain? Many thanks. Clarification 2: I'm doing this as I have private methods in a class that take said enum, and I do not want the enum's values exposed - so, for example, I do not want anyone to know that E is defined as enum E { FUNCTIONALITY_NORMAL, FUNCTIONALITY_RESTRICTED, FUNCTIONALITY_FOR_PROJECT_X } as project X is not something I want my users to know about. So, I wanted to forward declare the enum so I could put the private methods in the header file, declare the enum internally in the cpp, and distribute the built library file and header to people. As for the compiler - it's GCC.

  • boost::this_thread::disable_interruption usage confusion

    - by Evgenii
    boost/thread/pthread/shared_mutex.hpp contains this code: ... #include <boost/thread/detail/thread_interruption.hpp> ... class shared_mutex { ... void lock_shared() { boost::this_thread::disable_interruption do_not_disturb; boost::mutex::scoped_lock lk(state_change); while(state.exclusive || state.exclusive_waiting_blocked) { shared_cond.wait(lk); } ++state.shared_count; } ... }; but boost/thread/detail/thread_interruption.hpp does not contain implementation of disable_interruption, only the prototype. in boost_1_42_0/libs/thread/src/pthread we don't have the implementation too how does it work!???

  • c# 4.0 - best way to refactor a block of "If (something is Type) {}" statements?

    - by Andrew Johns
    I've got some code that looks like this, public void ResetControls(Control controlOnPage) { if (controlOnPage is TextBox) { ResetTextBoxControl(controlOnPage); } if (controlOnPage is MediaPicker) { ((MediaPicker)controlOnPage).Media = null; } if (controlOnPage is RelatedContentPicker) { ((RelatedContentPicker)controlOnPage).RelatedContentCollection = null; } ... ... foreach (Control child in controlOnPage.Controls) { ResetControls(child); } } The idea behind it is that I can pass a page to the method and it'll recursively reset all the controls on it to their default states - in the case of MediaPicker and RelatedContentPicker, these are user controls that I've created. FXCop warns me "Do Not Cast Unnecessarily" for this code - but I'm unsure how to rewrite it to make it better. Any ideas?

  • Display selectedAnnotation info

    When I use this: - (void)mapView:(MKMapView *)myMapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control { NSLog(@"SelectedAnnotations is %@", myMapView.selectedAnnotations); } It Displays this in the log. "<Annotation: 0x586cdb0>" Now this is a weird question, but how do I get the info from this Annotation? I have lost my mind. This is what is in the annotation. myAnnotation = [[Annotation alloc] init]; myAnnotation.dealName=[NSString stringWithFormat:@"%@",[tempValue objectForKey:@"name"]]; myAnnotation.subName=[NSString stringWithFormat:@"Price: $%@",[tempValue objectForKey:@"price"]]; myAnnotation.latitude = [NSNumber numberWithDouble:[[tempValue objectForKey:@"dealLatitude"] doubleValue]]; myAnnotation.longitude = [NSNumber numberWithDouble:[[tempValue objectForKey:@"dealLongitude"] doubleValue]]; myAnnotation.dealId = [NSNumber numberWithInt:[ [tempValue objectForKey:@"dId"] intValue ]]; Thanks for your help.

  • How to perform a cell deselection when a user returns to a table view?

    - by Panagiotis Korros
    I am using a UITableView to display a list of cells, when the user selects a cell then a new view appears by using the following code: - (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [self.navigationController pushViewController: detailsViewController animated: TRUE]; } By using the code above, the view is displayed correctly, but when I return back to the root table view, then the cell is still selected. I noticed, in many sdk examples, that the cell is deselected (with a nice animation) when the root view is poped pack, but I could not find the code that implemented this feature in any of the examples. I know that I can use: [tableView deselectRowAtIndexPath:indexPath animated: YES]; to implement this, but I am very curious on how these examples do it without using any code. Any ideas?

  • How to check for C++ copy ellision

    - by Steve
    I ran across this article on copy ellision in C++ and I've seen comments about it in the boost library. This is appealing, as I prefer my functions to look like verylargereturntype DoSomething(...) rather than void DoSomething(..., verylargereturntype& retval) So, I have two questions about this Google has virtually no documentation on this at all, how real is this? How can I check that this optimization is actually occuring? I assume it involves looking at the assembly, but lets just say that isn't my strong suit. If anyone can give a very basic example as to what successful ellision looks like, that would be very useful I won't be using copy ellision just to prettify things, but if I can be guaranteed that it works, it sounds pretty useful.

  • typedef fixed length array

    - by Rajorshi
    Hi, I have to define a 24-bit data type.I am using char[3] to represent the type. Can I typedef char[3] to type24? I tried it in a code sample. I put typedef char[3] type42; in my header file. The compiler did not complain about it. But when I defined a function void foo(type24 val) {} in my C file, it did complain. I would like to be able to define functions like type24_to_int32(type24 val) instead of type24_to_int32(char value[3]).

  • how do i close a frame yet open a new frame?(revisited)

    - by altvali
    I'm new at Java and I'm trying to do what the title says, my application has page A, a jpanel with some controls and a specific button, and when the user clicks the button i want page A to disappear and page B to appear (page B has controls that depend on the choices that are made by the user on page A). This has been asked before but there was no satisfactory answer. In the ActionListener implementation, namely public void ActionPerformed(ActionEvent e) from my jpanelForPageA class i can comfortably write this.setVisible(false), but how can i set page B to a visible state?

  • Session State ArrayList in Shopping Cart ASP.NET

    - by user330342
    Hi guys, I'm creating a shopping cart application and I'm having some issues with implementing a session state for my arraylist. in my page load i declared if (Session["Cart"] == null) { Session["Cart"] = new ArrayList(); } else { ArrayList cart = (ArrayList)Session["Cart"]; } to create the session if it doesn't exist yet. then i have an event handler for a button to add items to the arraylist protected void onClick_AddBooking(object sender, EventArgs e) { int ClassID = Convert.ToInt32(Request.QueryString.Get("Class_Id")); ArrayList cart1 = new ArrayList(); cart1 = Session["Cart"]; cart1.Add(ClassID); i'm guessing i just don't know how to handle session states yet, thus the confusion. I'm essentially storing the class_ID then when the student confirms i'll store that to the DB and associate that ID with the Class Details. Thanks in advance guys!

  • Polymorphic behavior not being implemented

    The last two lines of this code illustrate the problem: the compiler works when I use the reference to the object, but not when I assign the reference to an array element. The rest of the code is in the same package in separate files. BioStudent and ChemStudent are separate classes, as well as Student. package pkgPoly; public class Poly { public static void main(String[] arg) { Student[] stud = new Student[3]; // create a biology student BioStudent s1 = new BioStudent("Tom"); // create a chemistry student ChemStudent s2 = new ChemStudent("Dick"); // fill the student body with studs stud[0] = s0; stud[1] = s1; // compiler complains that it can't find symbol getMajor on next line System.out.println("major: " + stud[0].getMajor() ); // doesn't compile; System.out.println("major: " + s0.getMajor() ); // works: compiles and runs correctly } }
