  • Name the pattern - Create, Set, Execute, Destroy?

    - by Seb Nilsson
    I somewhere heard that the .NET Framework was built around specific pattern, which they tried to uphold as much as possible. var rsa = new RSACryptoServiceProvider(); // Create rsa.ImportParameters(GetParameters()); // Set byte[] encrypted = rsa.Encrypt(data, true); // Execute // Destroyed by garbage-collector Are there any variants of this? What are the general pros and cons?

  • strange characters at beginning of file

    - by luca
    there are strange characters at the beginning of a file I'm editing (using textmate..) I don't know when they appeared, they're invisible in textmate but my script that reads the file goes crazy.. this is the first few chars in the file (as seen with od command): 0000000 177377 000120 000105 000117 000120 000114 000105 000072 the first 2 shouldn't be there I think.. maybe they were caused by some strange dropbox sync? Or something else.. but they tend to reappear (I don't yet know when..) My question: what is that 177377 and a simple way to remove it in my ruby script? thanks

  • Good books and resources on user interface testing

    - by josefx
    I am looking for good books and articles on user-interface testing. What they should contain (one or more of): different test methods/strategies examples, use cases naming pros and cons for different methods something important I might have forgotten :-) What they should not be: Only about general tests and not gui tests describing a test framework limited to a single language What are the best resources you know of? (preferably language agnostic)

  • Visual Studio 2010 : Cant change target. Gives TargetFrameworkMoniker Error.

    - by maxima120
    I have a console application which has target .NET 2.0 It is very short but full of unsafe code. I converted it to VS 2010. I run it OK. When I try to change "target framework" in properties to 3.5 or 4.0 it shows message box: TargetFrameworkMoniker: Error parsing application configuration file at line 0. XML document must have a top level element. the target then stays 2.0 anyway... Any thoughts?

  • J2SE Client Server App: Client calls RMI method. Server handles RMI method and returns, but Client

    - by Mike
    J2SE Client Server App: Client calls RMI message. Server handles RMI method and returns, but Client never receives it. Any ideas how this could happen? Our attempted solution is to set client read timeouts and come up with a framework for resending requests or otherwise handling those failures gracefully. But really, I'd like to know any root causes for how this might happen rather than addressing the symptoms.

  • What do you use Sinatra for?

    - by Victor P
    Im confused about Sinatra (the ruby framework). Is it a lightweight Rails replacement or you can have them running side by side? Can you do a web application (as in Rails)? For example a twitter clone?

  • Including external C++ libraries in version control

    - by m0tive
    I'm currently starting a project which is going to be developed on a few different computer and I'm keeping in sync with bzr. In the project I'm using a couple of 3rd party libraries, like SDL. In the past I've just pushed a copy of the compiled library to my version control, but that usually seems to massively inflate the size of the branch and generally seem like a bad idea. Is that the normal practice, just pushing the required libraries, or is there a better way of added libraries to distributed version control like bzr or git? (I know on svn you can use svn:external to do something similar to this)

  • How many bits can be transfered through Ethernet at each time?

    - by Bobb
    I am writing a networking application. It has some unxpected lags. I need to calculate some figures but I cant find an information - how many bits can be transferes through Ethernet connection at each tick. I know that the resulting transfer rate is 100Mbps/1Gbps. But ethernet should use hardware ticks to sync both ends I suppose. So it moves data in ticks. So the question is how many ticks per second or how many bits per one tick used in ethernet. The actual connection is 100 Mbps full-duplex.

  • What are the elements of a team development suite?

    - by mhempey
    For small-to-large teams developing software together, what tools are used to form a comprehensive team development framework? Specifically, I'm looking for a comprehensive list of all the individual functions involved (e.g. source control, bug management, testing tools, project management), not specific product recommendations. I'm also not restricting the list to a particular methodology (e.g. Scrum).

    I'm trying to use System.Drawing.RotateFlipType in my settings file. This screenshot summarizes my problem: Each of RotateFlipType values is doubled, and some are missing.

  • Working with the IE cache from C# & WPF

    - by Eric
    I'm writing a program in C# using the WPF framework. I need to display images, and I'd like to cache them to avoid downloading them constantly. I can code my own cache, however, IE already has a caching system. I can find code to read entries out of the IE cache, however I've found nothing dealing with the issue of adding items to the cache. Is there a good way to do it, or should I just implement a separate cache?

  • Natural Language date and time parser for java

    - by Pranav
    Hey guys, I am working on a Natural Language parser which examines a sentence in english and extracts some information like name, date etc. for example: "Lets meet next tuesday at 5 PM at the beach." So the output will be something like : "Lets meet 15/09/2009 at 1700 hr at the beach" So basically, what i want to know is that is there any framework or library available for JAVA to do these kind of operations like parsing dates from a sentence and give a output with some specified format. Regards, Pranav

  • Action T synchronous and asynchronous

    - by raffaeu
    Hi everybody I have a contextmenustrip control that allows you to execute an action is two different flawours. Sync and Async. I am trying to covert everything using Generics so I did this: public class BaseContextMenu<T> : IContextMenu { private T executor ... public void Exec(Action<T> action){ action.Invoke(this.executor); } public void ExecAsync(Action<T> asyncAction){ ... } How I can write the async method in order to execute the generic action and 'do something' with the menu in the meanwhile? I saw that the signature of BeginInvoke is something like: asyncAction.BeginInvoke(thi.executor, IAsyncCallback, object);
