  • Can a telephony.Phone object be instantiated through the sdk?

    - by Tyler
    I am trying to get a phone object so that I can call and conference two numbers from within my application. I have tried using the static PhoneFactory.makeDefaultPhones((Context)this) but have not had any luck. String phoneFactoryName = "com.android.internal.telephony.PhoneFactory"; String phoneName = "com.android.internal.telephony.Phone"; Class phoneFactoryClass = Class.forName(phoneFactoryName); Class phoneClass = Class.forName(phoneName); Method getDefaultPhone = phoneFactoryClass.getMethod("getDefaultPhone"); Object phoneObject = getDefaultPhone.invoke(null); Error - Caused by java.lang.RuntimeException: PhoneFactory.getDefaultPhone must be called from Looper thread

  • How should I pass an object wrapping an API to a class using that API?

    - by Billy ONeal
    Hello everyone :) This is a revised/better written version of the question I asked earlier today -- that question is deleted now. I have a project where I'm getting started with Google Mock. I have created a class, and that class calls functions whithin the Windows API. I've also created a wrapper class with virtual functions wrapping the Windows API, as described in the Google Mock CheatSheet. I'm confused however at how I should pass the wrapper into my class that uses that object. Obviously that object needs to be polymorphic, so I can't pass it by value, forcing me to pass a pointer. That in and of itself is not a problem, but I'm confused as to who should own the pointer to the class wrapping the API. So... how should I pass the wrapper class into the real class to facilitate mocking?

  • How to access the Principal from a Java service object without using FlexContext?

    - by Marplesoft
    We're building some Java objects that are exposed via BlazeDS to our flex client application. So basically the BlazeDS messagebroker servlet instantiates and invokes methods on these objects in response to client requests. Works great. We're using app server-based authentication and have set up a security constraint on the <destination> elements in the remoting-config.xml file element to prevent unauthenticated clients from being able to access these remote java objects. Again, works fine. However, there are several places within the implementation of these java objects where we want to get the currently logged on user's username. Right now we are doing this via FlexContext.getUserPrincipal(), which gives access to this but we have a nagging concern that we don't like the idea that the implementation of these objects (the service layer) has a hard dependency on a BlazeDS class. But we're not sure how else to get access to this. The same applies to accessing the ServletContext and such. Any ideas?

  • How can I stop Silverlight DataForm immediately saving changes back to underlying object?

    - by Simon_Weaver
    I have a Silverlight master-details DataForm where the DataForm represents a street address. When I edit the Address1 textbox, the value gets automatically committed to the bound Address object once focus leaves the textbox. If I hit the Cancel button, then any changes are undone because Address implements IEditableObject and saves its state. The problem is that since any change is immediately propagated to the underlying object it will be shown in the master grid before the user has actually hit Save. I also have other locations where this data is shown. This is not a very good user experience. I've tried OneWay binding but then I can't commit back without manually copying all the fields over. The only thing I can think of doing is to create a copy of the data first or using OneWay binding, but they both seem a little clumsy. Does DataForm support this way of working?

  • WPF binding and pointers

    - by Eran
    hey guys, I have a WPF application that contains windows with few user controls and Coordinator object. the window and all its user controls pointing to an object, which instace is in the Coordinator, by thier DataContext. the problem is that I want to change this object (e.g. create new object()) in the Coordinator but I want all the dataContexts to point to the new object. I tried to send the object by ref to the window constructor but it didn't help. any idea about how can I rewrite the memory location that all pointers are pointing to? (I don't want to repalce the properties in object since its a lot of work nor to use a middle object that points to the replaced object) Thanks Eran

  • How do I manage disposing an object when I use IoC?

    - by Aval
    How do I manage disposing an object when I use IoC? My case it is Ninject. // normal explicit dispose using (var dc = new EFContext) { } But sometimes I need to keep the context longer or between function calls. So I want to control this behavior through IoC scope. // if i use this way. how do i make sure object is disposed. var dc = ninject.Get<IContext>() // i cannot use this since the scope can change to singleton. right ?? using (var dc = ninject.Get<IContext>()) { } Sample scopes Container.Bind<IContext>().To<EFContext>().InSingletonScope(); Container.Bind<IContext>().To<EFContext>().InRequestScope();

  • Does binarywriter.flush() also flush the underlying filestream object?

    - by jacob sebastian
    I have got a code snippet as follows: Dim fstream = new filestream(some file here) dim bwriter = new binarywriter(fstream) while not end of file read from source file bwriter.write() bwriter.flush() end while The question I have is the following. When I call bwriter.flush() does it also flush the fstream object? Or should I have to explicitly call fstream.flush() such as given in the following example: while not end of file read from source file bwriter.write() bwriter.flush() fstream.flush() end while A few people suggested that I need to call fstream.flush() explicitly to make sure that the data is written to the disk (or the device). However, my testing shows that the data is written to the disk as soon as I call flush() method on the bwriter object. Can some one confirm this?

  • How to use Page Object pattern with Cucumber and Webrat / Selenium?

    - by Will Sargent
    I'm looking at a cucumber test suite that is somewhat brittle right now; many small steps, and no knowledge of the page itself. I'd like to factor out the logic involved in the step definitions inside a series of Selenium PageObjects. As seen here. However, because I'm using Webrat and not Selenium, everything has to go through the Webrat model. So I cannot do class MyPage < Selenium::WebPage end because that adds a direct dependency. So I have to route everything through Webrat while still maintaining the Selenium Page object goodness. No documentation on this that I can see: if someone has anything on Webrat + PageModel I'd love to see it.

  • Extending User object in Django: User model inheritance or use UserProfile?

    - by Chris
    To extend the User object with custom fields, the Django docs recommend using UserProfiles. However, according to this answer to a question about this from a year or so back: extending django.contrib.auth.models.User also works better now -- ever since the refactoring of Django's inheritance code in the models API. And articles such as this lay out how to extend the User model with custom fields, together with the advantages (retrieving properties directly from the user object, rather than through the .get_profile()). So I was wondering whether there is any consensus on this issue, or reasons to use one or the other. Or even what the Django team currently think?

  • How can the DataView object reference not be set?

    - by dboarman-FissureStudios
    I have the following sample where the SourceData class would represent a DataView resulting from an Sql query: class MainClass { private static SourceData Source; private static DataView View; private static DataView Destination; public static void Main (string[] args) { Source = new SourceData(); View = new DataView(Source.Table); Destination = new DataView(); Source.AddRowData("Table1", 100); Source.AddRowData("Table2", 1500); Source.AddRowData("Table3", 1300324); Source.AddRowData("Table4", 1122494); Source.AddRowData("Table5", 132545); Console.WriteLine(String.Format("Data View Records: {0}", View.Count)); foreach(DataRowView drvRow in View) { Console.WriteLine(String.Format("Source {0} has {1} records.", drvRow["table"], drvRow["records"])); DataRowView newRow = Destination.AddNew(); newRow["table"] = drvRow["table"]; newRow["records"] = drvRow["records"]; } Console.WriteLine(); Console.WriteLine(String.Format("Destination View Records: {0}", Destination.Count)); foreach(DataRowView drvRow in Destination) { Console.WriteLine(String.Format("Destination {0} has {1} records.", drvRow["table"], drvRow["records"])); } } } class SourceData { public DataTable Table { get{return dataTable;} } private DataTable dataTable; public SourceData() { dataTable = new DataTable("TestTable"); dataTable.Columns.Add("table", typeof(string)); dataTable.Columns.Add("records", typeof(int)); } public void AddRowData(string tableName, int tableRows) { dataTable.Rows.Add(tableName, tableRows); } } My output is: Data View Records: 5 Source Table1 has 100 records.

  • Why eGet() in EMF returns Object rather than EObject?

    - by Gabriel Šcerbák
    I am working on some code using the EMF framework in Java, but it is really hard to use, e.g. I cannot implement OCL-like query API on top of EMF which would be type-safe. One of the reasons is that eGet() for a EStructuralFeature return just an Object, not EObject. So anything I would write must use much of null checking, type checking and type casting which is unsafe, not performant and cannot be generalized in a reusable way. Why doesn't EMF generate dummy implementations with EObject wrappers for arbitrary Object value? Implementing the EObject and hence the EClass interfaces even with simple throw UnsupportedOperationException is really a pain (the APIs are too big). The same holds for the eContainer() method which makes navigatinng the model upwards painful.

  • Dynamic Linq help, different errors depending on object passed as parameter?

    - by sah302
    I have an entityDao that is inherbited by everyone of my objectDaos. I am using Dynamic Linq and trying to get some generic queries to work. I have the following code in my generic method in my EntityDao : public abstract class EntityDao<ImplementationType> where ImplementationType : Entity { public ImplementationType getOneByValueOfProperty(string getProperty, object getValue){ ImplementationType entity = null; if (getProperty != null && getValue != null) { LCFDataContext lcfdatacontext = new LCFDataContext(); //Generic LINQ Query Here entity = lcfdatacontext.GetTable<ImplementationType>().Where(getProperty + " =@0", getValue).FirstOrDefault(); //.Where(getProperty & "==" & CStr(getValue)) } //lcfdatacontext.SubmitChanges() //lcfdatacontext.Dispose() return entity; } }         Then I do the following method call in a unit test (all my objectDaos inherit entityDao): [Test] public void getOneByValueOfProperty() { Accomplishment result = accomplishmentDao.getOneByValueOfProperty("AccomplishmentType.Name", "Publication"); Assert.IsNotNull(result); } The above passes (AccomplishmentType has a relationship to accomplishment) Accomplishment result = accomplishmentDao.getOneByValueOfProperty("Description", "Can you hear me now?"); Accomplishment result = accomplishmentDao.getOneByValueOfProperty("LocalId", 4); Both of the above work Accomplishment result = accomplishmentDao.getOneByValueOfProperty("Id", New Guid("95457751-97d9-44b5-8f80-59fc2d170a4c"))       Does not work and says the following: Operator '=' incompatible with operand types 'Guid' and 'Guid Why is this happening? Guid's can't be compared? I tried == as well but same error. What's even moreso confusing is that every example of Dynamic Linq I have seen simply usings strings whether using the parameterized where predicate or this one I have commented out: //.Where(getProperty & "==" & CStr(getValue)) With or without the Cstr, many datatypes don't work with this format. I tried setting the getValue to a string instead of an object as well, but then I just get different errors (such as a multiword string would stop comparison after the first word). What am I missing to make this work with GUIDs and/or any data type? Ideally I would like to be able to just pass in a string for getValue (as I have seen for every other dynamic LINQ example) instead of the object and have it work regardless of the data Type of the column.

  • Is it possible to connect slots of a model object to the GUI in QT4 -Designer?

    - by Robert0
    So I try to build a Model-View window using QTDesigner and C++. For that reason I created a QOBject derived class as my model. It provides slots and signals to access it like: setFileName(QString) or fileNameChanged(QString). I got a little into using signal drag and drop in QTDesigner and found it quite VA-Smalltalk-Like nice. After a while I was wondering if I could also connect my model to this. So is it possible to somehow introduce my model object into the Window/GUI and let QTDesigner connect signals and slots from the model object to the GUI. In essence: Write for me: connect( model, SIGNAL(fileNameChanged(QString)), ui->labelFn, SLOT(setText(QString))) connect( ui-textEdit2, SIGNAL(textChanged(QString)), model, SLOT(setFileName(QString))) Thanks for explaining

  • Can Automapper populate a strongly typed object from the data in a NameValueCollection?

    - by Seth Petry-Johnson
    Can Automapper map values from a NameValueCollection onto an object, where target.Foo receives the value stored in the collection under the "Foo" key? I have a business object that stores some data in named properties and other data in a property bag. Different views make different assumptions about the data in the property bag, which I capture in page-specific view models. I want to use AutoMapper to map both the "inherent" attributes (the ones that always exist) as well as the "dynamic" attributes (the ones that vary per view and may or may not exist).

  • What is the equivalent to Java's canvas object in C#?

    - by Winston
    I'm working on creating a basic application that will let a user draw (using a series of points) and I plan to do something with these points. If this were Java, I think I would probably use a canvas object and some Java2D calls to draw what I want. All the tutorials I've read on C#/Drawing involve writing your own paint method and adding it to the paint event for the form. However, I'm interested in having some traditional Form controls as well and I don't want to be drawing over them. So, is there a "Canvas" object where I can constrain what I'm drawing on? Also, is WinForms a poor choice given this use case? Would WPF have more features that would help enable me to do what I want? Or Silverlight?

  • How to I serialize a large graph of .NET object into a SQL Server BLOB without creating a large bu

    - by Ian Ringrose
    We have code like: ms = New IO.MemoryStream bin = New System.Runtime.Serialization.Formatters.Binary.BinaryFormatter bin.Serialize(ms, largeGraphOfObjects) dataToSaveToDatabase = ms.ToArray() // put dataToSaveToDatabase in a Sql server BLOB But the memory steam allocates a large buffer from the large memory heap that is giving us problems. So how can we stream the data without needing enough free memory to hold the serialized objects. I am looking for a way to get a Stream from SQL server that can then be passed to bin.Serialize() so avoiding keeping all the data in my processes memory. Likewise for reading the data back... Some more background. This is part of a complex numerical processing system that processes data in near real time looking for equipment problems etc, the serialization is done to allow a restart when there is a problem with data quality from a data feed etc. (We store the data feeds and can rerun them after the operator has edited out bad values.) Therefore we serialize the object a lot more often then we de-serialize them. The objects we are serializing include very large arrays mostly of doubles as well as a lot of small “more normal” objects. We are pushing the memory limit on a 32 bit system and make the garage collector work very hard. (Effects are being made elsewhere in the system to improve this, e.g. reusing large arrays rather then create new arrays.) Often the serialization of the state is the last straw that courses an out of memory exception; our peak memory usage is while this serialization is being done. I think we get large memory pool fragmentation when we de-serialize the object, I expect there are also other problem with large memory pool fragmentation given the size of the arrays. (This has not yet been investigated, as the person that first looked at this is a numerical processing expert, not a memory management expert.) Are customers use a mix of Sql Server 2000, 2005 and 2008 and we would rather not have different code paths for each version of Sql Server if possible. We can have many active models at a time (in different process, across many machines), each model can have many saved states. Hence the saved state is stored in a database blob rather then a file. As the spread of saving the state is important, I would rather not serialize the object to a file, and then put the file in a BLOB one block at a time. Other related questions I have asked How to Stream data from/to SQL Server BLOB fields? Is there a SqlFileStream like class that works with Sql Server 2005?

  • Is there a better way to create an object-oriented class with jquery?

    - by Devon
    I use the jquery extend function to extend a class prototype. For example: MyWidget = function(name_var) { this.init(name_var); } $.extend(MyWidget.prototype, { // object variables widget_name: '', init: function(widget_name) { // do initialization here this.widget_name = widget_name; }, doSomething: function() { // an example object method alert('my name is '+this.widget_name); } }); // example of using the class built above var widget1 = new MyWidget('widget one'); widget1.doSomething(); Is there a better way to do this? Is there a cleaner way to create the class above with only one statement instead of two?

  • How to handle optional variables of an object in Java?

    - by Arvanem
    Hi folks, For my trading program, I have a Merchant class. A given Merchant object may or may not have a particular special quality or bundle of special qualities. For example, one Merchant object may have the Stockbroker quality, another Merchant may have the Financial Services and Stockbroker qualities, and another Merchant may have no special qualities at all. My initial thought was to create a HashMap and a Qualities class as follows: Map<Qualities, Boolean> merchantQualities = new HashMap<Qualities, Boolean>(); The only problem is, there are at least 50 possible special qualities for Merchants, such that it would be extremely tiresome to subclass all the qualities from the Quality class. Is there a better way of coding for these optional special qualities and representing them in the Merchants class than a HashMap and subclassing a Qualities class?

  • How to convert an arbitrary object to String with JSTL? (calling toString())

    - by hstoerr
    Is there any way to call toString() on an object with the JSTL? (I need the String representation of an enum as index in a map in a JSP EL expression.) I hoped something like ${''+object} would work like in java, but JSTL isn't that nice, and there does not seem to be any function that does it. Clarification: I have a variable somemap that maps Strings to Strings, and I have a variable someenum that is an enumeration. I'd like to do something like ${somemap[someenum.toString()]}. (Of course .toString() does not work, but what does?)

  • Changing property type in class that implements interface with object type property.

    - by used2could
    I know the title is a bit confusing but bare with me. (I'm up for suggestions on a new title lol) I'm writing a TemplateEngine that will allow me to use my own markup in text based files. I'm wanting to add controls as plugins as the application matures. Currently i've got a structure like the following: interface IControl string Id object Value class Label : IControl string Id string Value class Repeater : IControl string Id List<IControl> Value Now you'll see the strange part right away in the Repeater class with the Value property. I was hoping that having the Value type as object in the interface would allow me the flexibility to expand the controls as i go along. The compiler doesn't like this and for good reason i guess. Does anyone have any suggestions how to accomplish this? Note: Please don't go into suggesting things like use Spark View Engine for templating. There is a reason i'm creating extra work for myself.
