  • Qmake does not specify a valid qt

    - by Comptrol
    After installing Qt SDK for Open Source C++ development on Mac OS by following the respective steps Note for the binary package: If you have the binary package, simply double-click on the Qt.mpkg and follow the instructions to install Qt. . Yes, that is all I have done to install Qt on MacOsX. Everything was going fine, until I run a sample application, of which compile output resulted in: No valid Qt version set. Set one in Preferences Error while building project qtilk When executing build step 'QMake' Canceled build. Then I tried to change the respective Qt version in Preferences and I hovered over the Path, I realized my mkspec isn't set: Then I tried querying qmake by qmake -query : QT_INSTALL_PREFIX:/ QT_INSTALL_DATA:/usr/local/Qt4.6 QT_INSTALL_DOCS:/Developer/Documentation/Qt QT_INSTALL_HEADERS:/usr/include QT_INSTALL_LIBS:/Library/Frameworks QT_INSTALL_BINS:/Developer/Tools/Qt QT_INSTALL_PLUGINS:/Developer/Applications/Qt/plugins QT_INSTALL_TRANSLATIONS:/Developer/Applications/Qt/translations QT_INSTALL_CONFIGURATION:/Library/Preferences/Qt QT_INSTALL_EXAMPLES:/Developer/Examples/Qt/ QT_INSTALL_DEMOS:/Developer/Examples/Qt/Demos QMAKE_MKSPECS:/usr/local/Qt4.6/mkspecs QMAKE_VERSION:2.01a QT_VERSION:4.6.2 QMAKE_MKSPECS seems to be set here?? Will setting my mkspec solve my building problem? I tried setting by typing export mkspec=macx-g++. Still, mkspec seems not to be set to anything. I am all ears waiting for your answers. Thanks in advance.

  • Problem with DataTrigger binding - setters are not being called

    - by aoven
    I have a Command bound to a Button in XAML. When executed, the command changes a property value on the underlying DataContext. I would like the button's Content to reflect the new value of the property. This works*: <Button Command="{x:Static Member=local:MyCommands.TestCommand}" Content="{Binding Path=TestProperty, Mode=OneWay}" /> But this doesn't: <Button Command="{x:Static Member=local:MyCommands.TestCommand}"> <Button.Style> <Style TargetType="{x:Type Button}"> <Style.Triggers> <DataTrigger Binding="{Binding Path=TestProperty, Mode=OneWay}" Value="True"> <DataTrigger.Setters> <Setter Property="Content" Value="Yes"/> </DataTrigger.Setters> </DataTrigger> <DataTrigger Binding="{Binding Path=TestProperty, Mode=OneWay}" Value="False"> <DataTrigger.Setters> <Setter Property="Content" Value="No"/> </DataTrigger.Setters> </DataTrigger> </Style.Triggers> </Style> </Button.Style> </Button> Why is that? * By "works" I mean the Content gets updated whenever I click the button. TIA

  • Why isn't my new object being seen? C#

    - by Dan
    I am getting ready to take a class at a college on C#. I have been reading up on it a lot and decided to start a fun project. Here is what my project consists of: Main Control Form Configuration Form Arduino Program.cs calls Configuration.cs at start. This is where pin modes for the Arduino are set and where a timer is set. When I set these values, they get sent to MainControl.cs. When I hit the "Save" button in Configuration.cs, a MainControl.cs object is created [[I am correct in that?]] All of those values that were sent by Configuration.cs had corresponding setters that set private static variables in MainControl.cs [[ I don't really know if that is the preferred way, I am most definetly open to any suggestion anyone has]] MainControl.cs uses its default constructor, and this constructor calls a method that creates an arduino object from one of the private variables (serialPort) [[ Using this Arduino class Firmata.NET ]] When the arduino object is created, I know (I guess I do) because the form takes a few seconds to come up (As opposed to not using serial port) My problem is this: I do not understand why nothing can see the object I have been very wordy, I apologize if I wasn't concise. Here is the code: public partial class CMainControl : Form { private static string serialPort; public CMainControl() { InitializeComponent(); createArduino(); updateConfig(); // Change label values to values set in configuration } private void createArduino() { Arduino arduino = new Arduino(serialPort); } In Configuration.cs, when I set the serial port through a combobox, the value is sent to MainControl.cs just fine. Here is the error I get: Error 1 The name 'arduino' does not exist in the current context C:\Programming\Visual Studio\Workhead Demo\Workhead Demo\CMainControl.cs 94 13 Workhead Demo Please let me know if anyone can help and/or offer pointers, and please let me know if I didn't post or format anything correctly. Thank you very much :)

  • Should I use a collection here?

    - by Eva
    So I have code set up like this: public interface IInterface { public void setField(Object field); } public abstract class AbstractClass extends JPanel implements IInterface { private Object field_; public void setField(Object field) { field_ = field; } } public class ClassA extends AbstractClass { public ClassA() { // unique ClassA constructor stuff } public Dimension getPreferredSize() { return new Dimension(1, 1); } } public class ClassB extends AbstractClass { public ClassB() { // unique ClassB constructor stuff } public Dimension getPreferredSize() { return new Dimension(42, 42); } } public class ConsumerA { public ConsumerA(Collection<AbstractClass> collection) { for (AbstractClass abstractClass : collection) { abstractClass.setField(this); abstractClass.repaint(); } } } All hunky-dory so far, until public class ConsumerB { // Option 1 public ConsumerB(ClassA a, ClassB b) { methodThatOnlyTakesA(a); methodThatOnlyTakesB(b); } // Option 2 public ConsumerB(Collection<AbstractClass> collection) { for (IInterface i : collection) { if (i instanceof ClassA) { methodThatOnlyTakesA((ClassA) i); else if (i instanceof ClassB) { methodThatOnlyTakesB((ClassB) i); } } } } public class UsingOption1 { public static void main(String[] args) { ClassA a = new ClassA(); ClassB b = new ClassB(); Collection<AbstractClass> collection = Arrays.asList(a, b); ConsumerA consumerA = new ConsumerA(collection); ConsumerB consumerB = new ConsumerB(a, b); } } public class UsingOption2 { public static void main(String[] args) { Collection<AbstractClass> collection = Arrays.asList(new ClassA(), new ClassB()); ConsumerA = new ConsumerA(collection); ConsumerB = new ConsumerB(collection); } } With a lot more classes extending AbstractClass, both options get unwieldly. Option1 would make the constructor of ConsumerB really long. Also UsingOption1 would get long too. Option2 would have way more if statements than I feel comfortable with. Is there a viable Option3? If it helps, ClassA and ClassB have all the same methods, they're just implemented differently. Thanks for slogging through my code!

  • Excel Automation From .NET - creating a new worksheet

    - by Andrew Shepherd
    I am attempting what seems like a simple task: using C# to create a new Excel document containing new worksheets. For some reason, I am getting a strange COM error (0x800A03EC) Has anyone managed to get this to work? Does anyone have suggestions as to how to troubleshoot this? I've isolated this into the minimum amount of code: using Microsoft.Office.Interop.Excel; using System.Diagnostics; namespace ExcelAutomation { public static class ExcelTests { public static void CreateWorksheet() { try { var app = new Microsoft.Office.Interop.Excel.Application(); app.Visible = true; var workBooks = app.Workbooks; var newWorkbook = app.Workbooks.Add(XlWBATemplate.xlWBATWorksheet); Worksheet existingWorksheet = (Worksheet)newWorkbook.Sheets[1]; Worksheet workSheet = (Worksheet)newWorkbook.Sheets.Add ( null, // before existingWorksheet, null, // 1, null //XlSheetType.xlWorksheet ); } catch (System.Runtime.InteropServices.COMException ex) { Trace.WriteLine(string.Format("Caught COMException. Message: \"{0}\"", ex.Message)); } } } } The output window now says: Caught COMException. Message: "Exception from HRESULT: 0x800A03EC"

  • How to serialize object containing NSData?

  • Best approach to storing image pixels in bottom-up order in Java

    - by finnw
    I have an array of bytes representing an image in Windows BMP format and I would like my library to present it to the Java application as a BufferedImage, without copying the pixel data. The main problem is that all implementations of Raster in the JDK store image pixels in top-down, left-to-right order whereas BMP pixel data is stored bottom-up, left-to-right. If this is not compensated for, the resulting image will be flipped vertically. The most obvious "solution" is to set the SampleModel's scanlineStride property to a negative value and change the band offsets (or the DataBuffer's array offset) to point to the top-left pixel, i.e. the first pixel of the last line in the array. Unfortunately this does not work because all of the SampleModel constructors throw an exception if given a negative scanlineStride argument. I am currently working around it by forcing the scanlineStride field to a negative value using reflection, but I would like to do it in a cleaner and more portable way if possible. e.g. is there another way to fool the Raster or SampleModel into arranging the pixels in bottom-up order but without breaking encapsulation? Or is there a library somewhere that will wrap the Raster and SampleModel, presenting the pixel rows in reverse order? I would prefer to avoid the following approaches: Copying the whole image (for performance reasons. The code must process hundreds of large (= 1Mpixels) images per second and although the whole image must be available to the application, it will normally access only a tiny (but hard-to-predict) portion of the image.) Modifying the DataBuffer to perform coordinate transformation (this actually works but is another "dirty" solution because the buffer should not need to know about the scanline/pixel layout.) Re-implementing the Raster and/or SampleModel interfaces from scratch (but I have a hunch that I will be unable to avoid this.)

  • Java - abstract class, equals(), and two subclasses

    - by msr
    Hello, I have an abstract class named Xpto and two subclasses that extend it named Person and Car. I have also a class named Test with main() and a method foo() that verifies if two persons or cars (or any object of a class that extends Xpto) are equals. Thus, I redefined equals() in both Person and Car classes. Two persons are equal when they have the same name and two cars are equal when they have the same registration. However, when I call foo() in the Test class I always get "false". I understand why: the equals() is not redefined in Xpto abstract class. So... how can I compare two persons or cars (or any object of a class that extends Xpto) in that foo() method? In summary, this is the code I have: public abstract class Xpto { } public class Person extends Xpto{ protected String name; public Person(String name){ this.name = name; } public boolean equals(Person p){ System.out.println("Person equals()?"); return this.name.compareTo(p.name) == 0 ? true : false; } } public class Car extends Xpto{ protected String registration; public Car(String registration){ this.registration = registration; } public boolean equals(Car car){ System.out.println("Car equals()?"); return this.registration.compareTo(car.registration) == 0 ? true : false; } } public class Teste { public static void foo(Xpto xpto1, Xpto xpto2){ if(xpto1.equals(xpto2)) System.out.println("xpto1.equals(xpto2) -> true"); else System.out.println("xpto1.equals(xpto2) -> false"); } public static void main(String argv[]){ Car c1 = new Car("ABC"); Car c2 = new Car("DEF"); Person p1 = new Person("Manel"); Person p2 = new Person("Manel"); foo(p1,p2); } }

  • C# Thread-safe Extension Method

    - by Wonko the Sane
    Hello All, I may be waaaay off, or else really close. Either way, I'm currently SOL. :) I want to be able to use an extension method to set properties on a class, but that class may (or may not) be updated on a non-UI thread, and derives from a class the enforces updates to be on the UI thread (which implements INotifyPropertyChanged, etc). I have a class defined something like this: public class ClassToUpdate : UIObservableItem { private readonly Dispatcher mDispatcher = Dispatcher.CurrentDispatcher; private Boolean mPropertyToUpdate = false; public ClassToUpdate() : base() { } public Dispatcher Dispatcher { get { return mDispatcher; } } public Boolean PropertyToUpdate { get { return mPropertyToUpdate; } set { SetValue("PropertyToUpdate", ref mPropertyToUpdate, value; } } } I have an extension method class defined something like this: static class ExtensionMethods { public static IEnumerable<T> SetMyProperty<T>(this IEnumerable<T> sourceList, Boolean newValue) { ClassToUpdate firstClass = sourceList.FirstOrDefault() as ClassToUpdate; if (firstClass.Dispatcher.Thread.ManagedThreadId != System.Threading.Thread.CurrentThread.ManagedThreadId) { // WHAT GOES HERE? } else { foreach (var classToUpdate in sourceList) { (classToUpdate as ClassToUpdate ).PropertyToUpdate = newValue; yield return classToUpdate; } } } } Obviously, I'm looking for the "WHAT GOES HERE" in the extension method. Thanks, wTs

  • Groovy on Grails: GORM and BitSets?

    I don't see anything in the official documentation about unsupported persistence data types, so I'm working under the assumption that types available in the Groovy language should be handled.

  • making java SingleFrameApplication to appear second

    - by Karel Bílek
    Sorry if this question will sound too chaotic, feel free to edit it. I have an application made entirely in netbeans, which uses SingleFrameApplication and auto-generated the GUI code, named "MyApp", and FrameView, named "MyView". Now, the MyApp somehow has the main() function, but the MyView has all the graphic elements.. I don't entirely understand how that happens, so used it as black box (it somehow created the window, I didn't have to care why). But now, I need the window to be only a window, opened by another JFrame. I don't know, how to accomplish that. MyApp, which is extending SingleFrameApplication, have these methods: public class MyApp extends SingleFrameApplication { @Override protected void startup() { show(new MyView(this)); } @Override protected void configureWindow(java.awt.Window root) { } public static MyApp getApplication() { return Application.getInstance(MyApp.class); } public static void main(String[] args) { launch(MyApp.class, args); } } MyView has these methods: public class MyView extends FrameView { public MyView(SingleFrameApplication app) { super(app); initComponents(); } private void initComponents() { //all the GUI stuff is somehow defined here } } Now, I have no clue how the two classes work, I just want this window, defined in MyView, to appear after another window, "ordinary" JFrame. How can I call this MyApp/MyView?

  • Why Finalize method not allowed to override

    - by somaraj
    I am new to .net ..and i am confused with the destructor mechanism in C# ..please clarify In C# destructors are converted to finalize method by CLR. If we try to override it (not using destructor ) , will get an error Error 2 Do not override object.Finalize. Instead, provide a destructor. But it seems that the Object calss implementation in mscorlib.dll has finalize defined as protected override void Finalize(){} , then why cant we override it , that what virtual function for . Why is the design like that , is it to be consistent with c++ destructor concept. Also when we go to the definition of the object class , there is no mention of the finalize method , then how does the hmscorlib.dll definition shows the finalize funtion . Does it mean that the default destructor is converted to finalize method. public class Object { public Object(); public virtual bool Equals(object obj); public static bool Equals(object objA, object objB); public virtual int GetHashCode(); public Type GetType(); protected object MemberwiseClone(); public static bool ReferenceEquals(object objA, object objB); public virtual string ToString(); }

  • How can I make this work with deep properties

    Given the following code... class Program { static void Main(string[] args) { Foo foo = new Foo { Bar = new Bar { Name = "Martin" }, Name = "Martin" }; DoLambdaStuff(foo, f => f.Name); DoLambdaStuff(foo, f => f.Bar.Name); } static void DoLambdaStuff<TObject, TValue>(TObject obj, Expression<Func<TObject, TValue>> expression) { // Set up and test "getter"...

Can anybody please help me to modify this so that I can create the setValueExpression for deep properties as well as shallow? Thanks.

  • Weird Issues with WPMU I Can't Figure Out

    - by HollerTrain
    I know I should post this on the WPMU forum, but no one writes me back and I'm just trying to find a larger audience hoping you have run into this issue as well. I have built a WPMU site for a client, and I am able to upload media into the Media Library and within a Post or Page perfectly. I thought my job was finished, yet the client can't upload any media at all. I'm located in Kentucky, they are located in New England (if that even matters). I had the client record their process of uploading as I thought they were simply not following my instructions for uploading, yet they are doing everything correctly. When uploading a file it goes through the process of allowing them to select a file and it says it uploads it, yet when it is finished uploading nothing is in the Media Library or in the Post. Video of the client trying to upload in Media Manager (http://www.screencast.com/users/CatherineWeber/folders/Jing/media/945d33fa-a752-45fd-9bc1-f76fc5a1814a) Video of the client trying to upload within a Post (http://www.screencast.com/users/CatherineWeber/folders/Jing/media/b5c60e25-f0b5-40c0-a820-c2fc9eb00906) Asking the client to disable Flash Uploader didn't work :( Yet, I can login to the WPMU site, access their blog's backend and can easily upload a ton of files. I am so lost at to what the issue is here. I am running version 2.8.4a, and will try to upgrade to latest release hoping this will fix things.

  • Strange \n in base64 encoded string in Ruby

    - by intellidiot
    The inbuilt Base64 library in Ruby is adding some '\n's. I'm unable to find out the reason. For this special example: irb(main):001:0> require 'rubygems' => true irb(main):002:0> require 'base64' => true irb(main):003:0> str = "1110--ad6ca0b06e1fbeb7e6518a0418a73a6e04a67054" => "1110--ad6ca0b06e1fbeb7e6518a0418a73a6e04a67054" irb(main):004:0> Base64.encode64(str) => "MTExMC0tYWQ2Y2EwYjA2ZTFmYmViN2U2NTE4YTA0MThhNzNhNmUwNGE2NzA1\nNA==\n" The \n's are at the last and 6th position from end. The decoder (Base64.decode64) returns back the old string perfectly. Strange thing is, these \n's don't add any value to the encoded string. When I remove the newlines from the output string, the decoder decodes it again perfectly. irb(main):005:0> Base64.decode64(Base64.encode64(str).gsub("\n", '')) == str => true More of this, I used an another JS library to produce the base64 encoded output of the same input string, the output comes without the \n's. Is this a bug or anything else? Has anybody faced this issue before? FYI, $ ruby -v ruby 1.8.7 (2008-08-11 patchlevel 72) [i486-linux]

  • Exam Questions that use .Demand or .LinkDemand COULD NOT BE ANY MORE CONFUSING OR AMBIGIOUS ????

    - by IbrarMumtaz
    I am 110% sure this is WRONG !!!! Q.12) You develop a library, and want to ensure that the functions in the library cannot be either directly or indirectly invoked by applications that are not running on the local intranet. What attribute would you add to each method? A. [UrlIdentityPermission(SecurityAction.RequestRefuse, Url="http://myintranet")] B. [UrlIdentityPermission(SecurityAction.LinkDemand, Url="http://myintranet")] (correct answer) C. [UrlIdentityPermission(SecurityAction.Demand, Url="http://myintranet")] D. [UrlIdentityPermission(SecurityAction.Assert, Url="http://myintranet")] Explanation Link-Demand should be used as it ensures that all callers in the call stack have the necessary permission. In this case it ensures that all callers in the call stack are on the local intranet. There is an indentical question on Transencer so I already had a clue what was goin but Transcender was much more informative that this drivel as it mentioned class level and not assembly level. It also mentioned that some callers maybe coming externally from the company intranet via authroised and authenticated credentials. With information is easy to see why .Demand on would be wong option to go for? So Transcender was right .... so I thgt fine, that makes sense. With think information still fresh in my brain I had a good idea was was going on in the question. To my surprise .Demand was wrong agin !!!! WHAT? I am really starting to hate this setting now? I cannot be any more p*ssed right now!!! :@ Thanks For Reading, Ibrar

  • Java: dangerous self-returning-recursive function by IOException?

    - by HH
    I had very errorsome Exception handling with if-clauses. An exception occurs if not found path. An exception returns the function again. The function is recursive. Safe? $ javac SubDirs.java $ java SubDirs Give me an path. . HELLO com TOASHEOU google common annotations base collect internal Give me an path. IT WON'T FIND ME, SO IT RETURNS ITSELF due to Exception caught Give me an path. $ cat SubDirs.java import java.io.*; import java.util.*; public class SubDirs { private List<File> getSubdirs(File file) throws IOException { List<File> subdirs = Arrays.asList(file.listFiles(new FileFilter() { public boolean accept(File f) { return f.isDirectory(); } })); subdirs = new ArrayList<File>(subdirs); List<File> deepSubdirs = new ArrayList<File>(); for(File subdir : subdirs) { deepSubdirs.addAll(getSubdirs(subdir)); } subdirs.addAll(deepSubdirs); return subdirs; } public static void search() { try{ BufferedReader in = new BufferedReader(new InputStreamReader(System.in)); String s; System.out.println("Give me an path."); while ((s = in.readLine()) != null && s.length() != 0){ SubDirs dirs = new SubDirs(); List<File> subDirs = dirs.getSubdirs(new File(s)); for ( File f : subDirs ) { System.out.println(f.getName()); } System.out.println("Give me an path."); } }catch(Exception e){ // Simple but is it safe? search(); } } public static void main(String[] args) throws IOException { search(); } }

  • Force compile-time linking of all classes in a SWC

    - by aaaidan
    Using Flash CS4, I am making a game that has a dozen or so sounds and a couple of music tracks. To cut down on publish/compile time, I have moved the sounds and music into an (external) SWC, which is located in a "Library Path" for the project. This works, but with a caveat... Until before I externalised the assets, I had been dynamically instantiating the Sound objects of the embedded sound by getting their classes with getDefinitionByName. // something like... var soundSubClass:Class = Class(getDefinitionByName(soundClassName)); var mySound:Sound = new soundSubClass(); But now that they're located in an external SWC, I need to have "concrete" references to the classes in order to load them like this, otherwise they are not included in the published SWF, and there is a runtime error when getDefinitionByName tries to get a class that doesn't exist. So, my question: in Flash Professional CS4, is there any way to force a library's assets to be included, regardless of whether they are statically linked? FlashDevelop has a compiler option "SWC Include Libraries", which is exactly what I want, and is distinct from the "SWC Libraries" option. The description of the "SWC Include Libraries" option is "Links all classes inside a SWC file to the resulting application SWF file, regardless of whether or not they are used." (Also, it's important to me that all the assets are contained within the one compiled SWF. Linking at runtime isn't what I'm after.)

  • Jquery UI Datepicker not displaying

    - by scott
    UPDATE I have reverted back to Jquery 1.3.2 and everything is working, not sure what the problem is/was as I have not changed anything else apart of the jquery and ui library versions. UPDATE END I having an issue with the JQuery UI datepicker. The datepicker is being attached to a class and that part is working but the datepicker is not being displayed. Here is the datepicker code I am using and the inline style that is being generated when I click in the input box that has the class ".datepicker". $('.datepicker').datepicker({dateFormat:'dd/mm/yy'}); display:none; left:418px; position:absolute; top:296px; z-index:1; If I change the display:none to display:block the datepicker works fine except it dosen't close when I select a date. Jquery libraries in use: jQuery JavaScript Library v1.4.2 jQuery UI 1.8 jQuery UI Widget 1.8 jQuery UI Mouse 1.8 jQuery UI Position 1.8 jQuery UI Draggable 1.8 jQuery UI Droppable 1.8 jQuery UI Datepicker 1.8
