• How to get right values from Views touch event

  - by Pinker

  I have a problem with implementing touch events on GLSurfaceView. Views size is 1280x696, because of android (tablet) status bar at bottom with soft keys, time etc.., (screen resolution is 1280x800), but OnTouchListener is receiving touch events with coords [646.0,739.0], and thus my gluunproject method fails to return correct values is there any way to return events that respect these boundaries? or how should I recalculate the position?

• class vs structure c#

  - by Enriquev

  I'm doing course 3354 (Implementing System Types and Interfaces in the .NET Framework 2.0) and it is said that for simple classes, with members variables and functions, it is better to use a struct than a class because of overhead. I have never heard of such a thing, what is the validity of this claim?

• NamespaceContext and using namespaces with XPath

  - by Jherico

  Resolving an xpath that includes namepsaces in Java appears to require the use of a NamespaceContext object, mapping prefixes to namespace urls and vice versa. But I can find no mechanism for getting a NamespaceContext other than implementing it myself. This seems counter-intuitive. Is there any easy way to acquire a NamespaceContext from a document, or to create one, or failing that, to forgo prefixes altogether and specify the xpath with fully qualified names?

• What standards and best practices should I follow to write interoperable portlets or web gadgets?

  - by Adam

  I am trying to design the standards and patterns for implementing portlets/web gadgets with the main goal of maximizing interoperability if those components were hosted in a Java app server framework or within an existing ASP.NET technology (SharePoint webparts), or a client side-only framework. Is there any guidance anywhere of the parts of different portlet standards that are shared between most portal frameworks? Is the best I can hope for is to adhere to the JSR 168 and 286 standards and hitch my wagon to Java?

• Xcode C++ debugging

  - by mousebird

  I'm looking for a way to have the Xcode IDE pick up on the contents of my weird Boost template classes. Basically, classes complex enough that Xcode can't display their contents correctly. Is there something like the Objective C -description method or toString() in Java that Xcode will look for? At the moment I'm just implementing print() methods and invoking them in gdb, but that's likely to confuse other developers.

• Disposing the members that implement IDisposable.

  - by Amby

  In my Dispose methods (like the one below), everytime i want to call someObj.Dispose() i also have a check for someObj!=null. Is that because of bad design on my part? Is their a cleaner way to ascertain that Dispose of all the members (implementing IDisposable) being used in an object is called without having a risk of NullReference exception ? protected void Dispose(bool disposing) { if (disposing) { if (_splitTradePopupManager != null) { _splitTradePopupManager.Dispose(); } } } Thanks for your interest.

• Would ViewModels fit in the Model View Presenter pattern?

  - by Jonn

  Having used ViewModels in MVC, I was wondering if applying the same to the MVP pattern is practical. I only have a few considerations, one being that MVP is already fairly hard to implement (with all the additional coding, not much on the seeming complexity) or that ViewModels already have a slightly similar way of modeling data or entities. Would adding another layer in the form of ViewModels be redundant or is it a logical abstraction that I, as one implementing the MVP pattern, should adhere to?

• Android as SIP to GSM gateway

  - by user346034

  Soon I could use a SIP to GSM gateway, because I'll need to make phone calls from Germany to a mobile phone in Czech Republik. Hence, I thought about implementing one. Now, the questions are: Does such a solution already exist (for a reasonable price)? Is it possible to redirect a (voice) stream to a GSM connection with the available Android APIs (SDK or NDK)? Ideas, suggestions, comments are highly welcome.

• Pass value from one ASP.NET app to another via HTTP Header

  - by Whiskey-Tango-Foxtrot

  We are implementing a single sign on mechanism in an enterprise environment, where the token is shared between applications using HTTP header. Now, in order to do the integration test, I need to write an application to simulate this. Is there any way in ASP.NET where I can redirect to another web-page and pass a custom HTTP header in the process? Thanks

• Which is more robust and scalable method?

  - by Dhruv Arya

  I am implementing a distributed chat system, in this system we have the following options : Make the client and server running at each node run as separate threads. The server acting as the receiver will be running as the daemon thread and the client taking the user input as a normal thread. Fork two processes one for the client and one for the server. I am not able to reason out with which one to proceed. Any insight would be great !

• IO Exception: directory name is invalid C#

  - by Bi

  My C# application throws a System.IO.IOExcepton (The directory name is invalid) for the following code for implementing a filewatcher: public void OnChanged(object source, FileSystemEventArgs e) { DirectoryInfo dList = new DirectoryInfo(e.FullPath); FileInfo[] TxtFiles = dList.GetFiles("*.TXT"); } e.FullPath is "C:/Documents and Settings/Bi/Application Data/TestApp/Reports\\0MA01P62240_000005798_TRI_4947712701738551.TXT". If you notice it seems to append a "\\" to the path when it tracks the file. Any idea what the problem may be? Thanks

• Design pattern for adding / removing elements

  - by de3

  Wikipedia's definition for Iterator pattern design: the Iterator pattern is a design pattern in which iterators are used to access the elements of an aggregate object sequentially without exposing its underlying implementation. Iterator interface in java provides the following methods hasNext() next() remove() Is there a pattern design, or a java interface for inserting / deleting elements, and getting length of the aggregate object, in addition to iterating them? I know remove() is an optional method that can be used once per call to next(), but I am implementing a circular FIFO array and need a method delete() independent of iterator's next().

• Database Schema for Machine Tags?

  - by Gabriel

  Machine tags are more precise tags: http://www.flickr.com/groups/api/discuss/72157594497877875. They allow a user to basically tag anything as an object in the format object:property=value Any tips on a rdbms schema that implements this? Just wondering if anyone has already dabbled with this. I imagine the schema is quite similar to implementing rdf triples in a rdbms

I've gotten the impression that Python is good for this kind of stuff. but is this feasible to do? how would one go about implementing something like this? also, assume that the site does not let you visit something like www.mysampleurl.com/files/
