• JAXB, downcast an unmarshalled class

  - by elgcom

  I define two XML type (base and derived types). <xs:complexType name="ParentType"> ... </xs:complexType> <xs:complexType name="ChildType"> <xs:complexContent> <xs:extension base="ParentType"> ... </xs:complexContent> </xs:complexType> Now, I have an XML instance of ChildType. The question, If I once unmarshall the XML into ParentType java object, can I downcast the java object to its subclass of ChildType? Is that possible to that? thanks

• Benchmark for a .NET WinPcap wrapper

  - by brickner

  I'm developing a .NET wrapper for WinPcap called Pcap.Net. I'm trying to make sure this wrapper has high performance and I want to compare it to WinPcap and to other .net wrappers for WinPcap. The features I want to profile are: WinPcap native features (sending packets in different ways, receiving packets in different ways...) Interpreting packets that Pcap.Net knows how to interpret (like Etherent, IPv4, UDP, TCP, ICMP, ...) Building packet that Pcap.Net knows how to build (the same types it knows how to interpret). I also want to be able to profile the benchmark using Visual Studio 2010 Ultimate profiling tools. My question is: What should my benchmark exactly do to cover these issues and how would you suggest to build it?

• Java getMethod with superclass parameters in method

  - by Jonathon

  Given: class A { public void m(List l) { ... } } Let's say I want to invoke method m with reflection, passing an ArrayList as the parameter to m: List myList = new ArrayList(); A a = new A(); Method method = A.class.getMethod("m", new Class[] { myList.getClass() }); method.invoke(a, Object[] { myList }); The getMethod on line 3 will throw NoSuchMethodException because the runtime type of myList is ArrayList, not List. Is there a good generic way around this that doesn't require knowledge of class A's parameter types?

• Overload assignment operator for assigning sql::ResultSet to struct tm

  - by Luke Mcneice

  Are there exceptions for types which can't have thier assignment operator overloaded? Specifically, I'm wanting to overload the assignment operator of a struct tm (from time.h) so I can assign a sql::ResultSet to it. I already have the conversion logic: sscanf(sqlresult->getString("StoredAt").c_str(), "%d-%d-%d %d:%d:%d", &TempTimeStruct->tm_year, &TempTimeStruct->tm_mon, &TempTimeStruct->tm_mday, &TempTimeStruct->tm_hour, &TempTimeStruct->tm_min, &TempTimeStruct->tm_sec); I tried the overload with this: tm& tm::operator=(sql::ResultSet & results) { /*CODE*/ return *this; } However VS08 reports: error C2511: 'tm &tm::operator =(sql::ResultSet &)' : overloaded member function not found in 'tm'

• C# settings using ApplicationSettingsBase - roaming and common

  - by Mark Pim

  I'm using the Windows Forms Application settings architecture (or however you're supposed to refer to it) and am successfully saving user settings to AppData. What I want to do is have some settings common to all users of a particular machine and some settings which roam with users across machines. For example I have some settings relating to a peripheral attached to the computer (model, settings etc.) and some user preferences like user interface colours. The colours preferences should roam with the user, but the peripheral settings should stay on the local computer no matter who's logged on. How can I mark these types of settings so that some get stored in /AppData/... and some in /AppData? Note that I don't want Application level settings - each computer the app will be installed on will have different settings. I'm targetting .Net 3.0 if that makes a difference.

• Good websites and/or books to learn game algorithms?

  - by Moshe

  I'm interested in learning video game algorithms. (For iPhone particularly, but generally as well. I assume certain concepts are the same.) I am best off (personally) learning from a book but websites are useful too. What has helped you learn game programming algorithms and concepts? EDIT: As per request, I'll clarify the types of algorithms... I was looking for any algorithms really, but I guess I was interested in (top-down view) platformer algorithms, but, now that you mention it, Seth, I do wonder about chess...

• Should I Make These Vectors Classes or Structs in C#

  - by dewald

  I am creating a geometry library in C# and I will need the following immutable types: Vector2f (2 floats - 8 bytes) Vector2d (2 doubles - 16 bytes) Vector3f (3 floats - 12 bytes) Vector3d (3 doubles - 24 bytes) Vector4f (4 floats - 16 bytes) Vector4d (4 doubles - 32 bytes) I am trying to determine whether to make them structs or classes. MSDN suggests only using a struct if the size if going to be no greater than 16 bytes. That reference seems to be from 2005. Is 16 bytes still the max suggested size? I am sure that using structs for the float vectors would be more efficient than using a class, but what should I do about the double vectors? Should I make them structs also to be consistent, or should I make them classes?

• Best practice for submits redirecting to another page in MVC2?

  - by blesh

  I have a situation with my MVC2 app where I have multiple pages that need to submit different information, but all need to end up at the same page. In my old Web Forms app, I'd have just accomplished this in my btnSave_Click delegate with a Redirect. There are three different types of products, each of which need to be saved to the cart in a completely different manner from their completely different product pages. I'm not going to get into why or how they're different, just suffice to say, they're totally different. After they're saved to the cart, I need to "redirect" to the Checkout view. But it should be noted, that you can also just browse straight to the Checkout view without having to submit any products to add to the cart. Here's a diagram of what I'm trying to accomplish, and how I think I need to handle it: Is this correct? It seems like a common scenario, but I haven't seen any examples of how I should handle this. Thank you all in advance.

• Using CSS Classes for indivdual effects - opinions?

  - by Cool Hand Luke UK

  Hey, Just trying to canvas some opinions here. I was wondering how people go about adding individual effects to html elements. Take this example: you have three types of h1 titles all the same size but some are black some are gold and some are white. Some have a text-shadow etc. Would you create separate CSS classes and add them do the h1 tag or would you create a new single class for each different h1 title type (with grouped CSS elements)? With singular class for each effect you can build up combos of classes in html class="gold shadow" but also how would you name them. For example its bad practice to give classes and id names associated to colours, because it doesn't define what it does well. However is this ok with textual CSS classes? Just wondering what others do, I know there are no hard and fast rules. Cheers.

• What does the EC2 command line say when a machine won't start?

  - by OneSolitaryNoob

  When starting an instance on Amazon EC2, how would I detect a failure, for instance, if there's no machine available to fulfill my request? I'm using one of the less-common machine types and am concerned it won't start up, but am having trouble finding out what message to look for to detect this. I'm using the EC2 commandline tools to do this. I know I can look for 'running' when I do ec2-describe-instance to see if the machine is up, but don't know what to look for to see if the startup failed. Thanks!

• Manual testing Vs Automated testing

  - by mgj

  Respected all, As many know testing can be mainly classified into manual and automated testing. With regard to this certain questions come to mind. Hope you can help... They include: What is the basic difference between the two types of testing? What are the elements of challenges involved in both manual and automated testing? What are the different skill sets required by a software tester for manual and automated testing respectively? What are the different job prospects and growth opportunities among software testers who do manual testing automated testing respectively? Is manual testing under rated to automated testing in anyway(s)? If yes, kindly specify the way. How differently are the manual testers treated in comparison to automated testers in the corporate world?( If they truly are differentiated in any terms as such ) I hope you can share your knowledge in answering these questions.. Thank you for your time..:)

• Review my ASP.NET Authentication code.

  - by Niels Bosma

  I have had some problems with authentication in ASP.NET. I'm not used most of the built in authentication in .NET. I gotten some complaints from users using Internet Explorer (any version - may affect other browsers as well) that the login process proceeds but when redirected they aren't authenticated and are bounced back to loginpage (pages that require authentication check if logged in and if not redirect back to loginpage). Can this be a cookie problem? Do I need to check if cookies are enabled by the user? What's the best way to build authentication if you have a custom member table and don't want to use ASP.NET login controls? Here my current code: using System; using System.Linq; using MyCompany; using System.Web; using System.Web.Security; using MyCompany.DAL; using MyCompany.Globalization; using MyCompany.DAL.Logs; using MyCompany.Logging; namespace MyCompany { public class Auth { public class AuthException : Exception { public int StatusCode = 0; public AuthException(string message, int statusCode) : base(message) { StatusCode = statusCode; } } public class EmptyEmailException : AuthException { public EmptyEmailException() : base(Language.RES_ERROR_LOGIN_CLIENT_EMPTY_EMAIL, 6) { } } public class EmptyPasswordException : AuthException { public EmptyPasswordException() : base(Language.RES_ERROR_LOGIN_CLIENT_EMPTY_PASSWORD, 7) { } } public class WrongEmailException : AuthException { public WrongEmailException() : base(Language.RES_ERROR_LOGIN_CLIENT_WRONG_EMAIL, 2) { } } public class WrongPasswordException : AuthException { public WrongPasswordException() : base(Language.RES_ERROR_LOGIN_CLIENT_WRONG_PASSWORD, 3) { } } public class InactiveAccountException : AuthException { public InactiveAccountException() : base(Language.RES_ERROR_LOGIN_CLIENT_INACTIVE_ACCOUNT, 5) { } } public class EmailNotValidatedException : AuthException { public EmailNotValidatedException() : base(Language.RES_ERROR_LOGIN_CLIENT_EMAIL_NOT_VALIDATED, 4) { } } private readonly string CLIENT_KEY = "9A751E0D-816F-4A92-9185-559D38661F77"; private readonly string CLIENT_USER_KEY = "0CE2F700-1375-4B0F-8400-06A01CED2658"; public Client Client { get { if(!IsAuthenticated) return null; if(HttpContext.Current.Items[CLIENT_KEY]==null) { HttpContext.Current.Items[CLIENT_KEY] = ClientMethods.Get<Client>((Guid)ClientId); } return (Client)HttpContext.Current.Items[CLIENT_KEY]; } } public ClientUser ClientUser { get { if (!IsAuthenticated) return null; if (HttpContext.Current.Items[CLIENT_USER_KEY] == null) { HttpContext.Current.Items[CLIENT_USER_KEY] = ClientUserMethods.GetByClientId((Guid)ClientId); } return (ClientUser)HttpContext.Current.Items[CLIENT_USER_KEY]; } } public Boolean IsAuthenticated { get; set; } public Guid?

• Storing Interface type in ASP.NET Profile

  - by NathanD

  In my ASP.NET website all calls into the data layer return entities as interfaces and the website does not need to know what the concrete type is. This works fine, but I have run into a problem when trying to store one of those types into the user Profile. My interface implements ISerializable, like the following: public interface IInsured : IPerson, IEntity, ISerializable and the concrete type in the datalayer does implement ISerializable. My Profile property in web.config is: <add name="ActiveInsured" type="FacadeInterfaces.IInsured" serializeAs="Binary" defaultValue="[null]"/> It compiles just fine, but I get a runtime error on Profile.Save() saying that the interface cannot be serialized. I have also tried it with serializeAs="Xml". I thought that if my interface implemented ISerializable it would work. Anybody had this problem before or know of a workaround?

• Using SCons as a build engine for distutils

  - by pygabriel

  I have a python package with some C code needed to build an extension (with some non-trivial building needs). I have used SCons as my build system because it's really good and flexible. I'm looking for a way to compile my python extensions with SCons ready to be distributed with distutils. I want that the user simply types setup.py install and get the extension compiled with SCons instead of the default distutils build engine. An idea that comes to mind is to redefine build_ext command in distutils, but I can't find extensive documentation for it. Any suggestion?

• Eclipse + PDT hides files extensions

  - by pzearfoss

  Eclipse is now hiding file extensions in PDT, in the PHP Explorer. They show up on tabs when the file is opened. This applies to files of all types. While annoying, it didn't become problematic until I started including the .htaccess files in the list. They now show up with no filename at all. I've scoured the prefs and the web looking for a resolution. Anyone had this happen or have an idea of how to fix it? Running Eclipse 3.5.2 PDT 2.1 on MacOS 10.5

• Convert From Custom List to List of String

  - by Paul Johnson

  Hi all I have the following code: Public Shared Function ConvertToString(ByVal list As IList) As String Dim strBuilder = New System.Text.StringBuilder() Dim item As Object For Each item In list strBuilder.Append(obj.ToString()) strBuilder.Append(",") Next Return strBuilder.ToString(strBuilder.Length - 1) End Function The intention is to convert an IList of custom objects to a string equivalent comprising each element in the Ilist. Unfortunately I can't seem to find a way to get the underlying data of the custom object, and of course as in the above example, using object simply gives me a string of types definitions, rather than access to the underlying data. Any assistance much appreciated. Paul.

• C# Winforms ADO.NET - DataGridView INSERT starting with null data

  - by Geo Ego

  I have a C# Winforms app that is connecting to a SQL Server 2005 database. The form I am currently working on allows a user to enter a large amount of different types of data into various textboxes, comboboxes, and a DataGridView to insert into the database. It all represents one particular type of machine, and the data is spread out over about nine tables. The problem I have is that my DataGridView represents a type of data that may or may not be added to the database. Thus, when the DataGridView is created, it is empty and not databound, and so data cannot be entered. My question is, should I create the table with hard-coded field names representing the way that the data looks in the database, or is there a way to simply have the column names populate with no data so that the user can enter it if they like? I don't like the idea of hard-coding them in case there is a change in the database schema, but I'm not sure how else to deal with this problem.

• iPhone modalView unwanted offset

  - by Chonch

  Hey, I have a UITabBarController with three view controllers (from three different types). On one of the view controllers, I want to display a modalViewController. Once a UIButton on the screen is pressed, I perform this action: AboutViewController *modalViewController = [[AboutViewController alloc] initWithNibName:@"AboutScreen" bundle:nil]; [self presentModalViewController:modalViewController animated:YES]; like I always do in order to display a modal view... The problem is, that while the modal view is being displayed (while it is moving from the bottom of the screen), a 20 pixels grey strip is showing on the bottom of the screen (the same size as the status bar on the top). Once the modal view reaches its final location, the strip disappears. Needless to say this doesn't look good (to say the least). Does anybody know why this may happen? Thanks,

• Parsing plain Win32 PE File (Exe/DLL) in C#.NET

  - by Usman

  Hello, I need to parse plain Win32 DLL/Exe and need to get all imports and exports from it and to show it on console or GUI(say Win Forms). Is it possible to parse Win32 DLL/Exe in C#.NET, read its export table,import table and get managed types from it. As its unmanaged PE(.NET doesn't allows you to convert unmanaged PE files to managed .NET assemblies, only it generates COM managed assemblies). So how to parse export and import tables of PE files and take all methods(signatures from it) in managed form.(e.g if char* as argument, it should display as IntPtr) Regards Usman

• Table image not showing, "Pop an autorelease pool" error

  - by Graeme

  hi, I have a UITableView which uses the following code to display an image in a Table View cell: cell.imageView.layer.masksToBounds = YES; cell.imageView.layer.cornerRadius = 5.0; UIImage *image = [UIImage imageNamed:[[color types] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]]; if ( image ) { cell.imageView.image = [image imageScaledToSize:CGSizeMake(50, 50)]; } It works fine on the iPhone simulator, but when I try it on a real iPhone the iPhone doesn't show. Instead in the console in debugging mode, I get this error: attempt to pop an unknown autorelease pool (0x851e00) Any help would be great, thanks.

• Is there a J2SE sensor API?

  - by Martin Strandbygaard

  Does anyone know of a "standardized" Java API for working with sensors, and which is closely tied to J2ME as is the case with JSR 256? I'm writing a Java library for interfacing with a sensor network consisting of several different types of sensors (mostly simple stuff such as temperature, humidity, GPS, etc.). So far I've rolled my own interface, and users have to write apps against this. I would like to change this approach and implement a "standard" API so that implementations aren't that closely tied to my library. I've looked at JSR 256, but that really isn't a great solution as it's for J2ME, and my library is mostly used by Android devices or laptops running the full J2SE.

• UITableViewCellStyleDefault image size

  - by Rob Bonner

  Hello all, I am getting some odd behavior from stock table cells, or maybe not odd, maybe I am making some assumptions. I create the cells as follows: cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; Then I assign an image to the default imageView property. My image usually comes in from a user, so it might be larger than the default size. To take care of this I: [cell.imageView setContentMode:UIViewContentModeScaleAspectFit]; which I expected to scale the image for me within the control, but in reality, the images are all over the map. So, is there a proper way to constrain the image in stock cell types? Thanks in advance!
